Abstract

A casing device and an insertion structure thereof are provided. The casing device includes a first casing, a second casing, and an insertion structure. The second casing has an engagement structure. The insertion structure includes a tamperproof element. The tamperproof element has one end extended outward to form two barb-like protruding portions and the other end protrudingly provided with a leaf spring. The leaf spring includes resilient protruding plates protrudingly formed on the outer surface of the tamperproof element. Since the resilient protruding plates and the engagement structure are engaged with each other, the insertion structures can clamp the first casing and the second casing to prevent consumers from dismantling an electronic device enclosed by the casing device but enable the electronic device manufacturers to confirm whether the casing device has been inappropriately dismantled by the consumers, thereby settling disputes over damages liability between a consumer and a manufacturer.

First claim

What is claimed is:

1. An insertion structure, comprising:
a tamperproof element comprising a case sleeve and a penetrating post, wherein the case sleeve comprises an outer surface, an end extended outward to form two barb-like protruding portions and another end protrudingly provided with a leaf spring, wherein the leaf spring comprises a plurality of resilient protruding plates protrudingly formed on the outer surface;
wherein the penetrating post is penetratingly disposed in the case sleeve and abuts against the barb-like protruding portions; and
wherein the penetrating post has a rod portion and a head portion extending from a top of the rod portion, with the rod portion penetratingly disposed in the case sleeve, wherein two slots are disposed laterally at a bottom of the head portion, respectively, allowing the two barb-like protruding portions to engage with the two slots and abut against inner walls of the slots, respectively.

2. The insertion structure of claim 1 , wherein the barb-like protruding portions are made of a metal which exhibits resilience.

3. The insertion structure of claim 1 , wherein the resilient protruding plates are disposed at an outer rim of the case sleeve, arranged spirally in one turn, and spaced apart from each other.

4. The insertion structure of claim 1 , wherein the resilient protruding plates tilt and align with the barb-like protruding portions to extend, with an acute angle defined by and between each said resilient protruding plate and the outer surface.

5. The insertion structure of claim 1 , wherein the case sleeve is formed from a U-shaped metallic strip, and the two barb-like protruding portions form two flaps by extending the two terminal ends of the U-shaped metallic strip outward and bending them reversely, wherein the resilient protruding plates are formed by cutting the U-shaped metallic strip bilaterally along a cutting line and then folding the U-shaped metallic strip outward about the cutting line.

6. A casing device, comprising:
a first casing with a surface having an opening and another surface having a through hole in communication with the opening;
a second casing having a penetrating hole in communication with the through hole, wherein the second casing and the first casing can be closed; and
the insertion structure of claim 1 , wherein the tamperproof element is penetratingly disposed in the through hole and the penetrating hole, with the barb-like protruding portions abutting against a bottom of the opening, wherein the plurality of resilient protruding plates and an engagement structure disposed inside the penetrating hole are engaged with each other such that a portion of the first casing and a portion of the second casing are clamped between the barb-like protruding portions and the plurality of resilient protruding plates.

7. The casing device of claim 6 , wherein the engagement structure comprises an internal thread disposed on an inner wall of the penetrating hole, wherein the plurality of resilient protruding plates and the internal thread are engaged with each other.

8. The casing device of claim 7 , wherein the leaf springs are in a number of plurality and vertically spaced apart, wherein terminal ends of two adjacent ones of the resilient protruding plates vertically spaced apart are separated by a distance which is a multiple of a pitch of the internal thread.

9. The casing device of claim 6 , wherein the engagement structure comprises a stop ring disposed on an inner wall of the penetrating hole, wherein the plurality of resilient protruding plates and the stop ring are engaged with each other.

10. The casing device of claim 6 , further comprising a through pipe with an outer wall abutting against an inner wall of the penetrating hole, wherein the engagement structure comprises a flange disposed on an inner wall of the through pipe, wherein the plurality of resilient protruding plates and the flange are engaged with each other.

11. The casing device of claim 10 , wherein the outer wall of the through pipe extends to form a sandwiched block sandwiched between the first casing and the second casing.

12. The casing device of claim 6 , wherein an area of the opening is larger than an area of the through hole, thereby allowing the first casing to have an annular block formed at an outer rim of the through hole, wherein the annular block is sandwiched between the barb-like protruding portions and the plurality of resilient protruding plates.

13. An insertion structure, comprising:
a tamperproof element comprising a case sleeve and a penetrating post, the case sleeve comprising an outer surface, an end extended outward to form two barb-like protruding portions and another end protrudingly provided with a leaf spring, wherein the leaf spring comprises a plurality of resilient protruding plates protrudingly formed on the outer surface;
wherein the penetrating post is penetratingly disposed in the case sleeve and abuts against the barb-like protruding portions; and
wherein windows are disposed on the case sleeve and correspond in position to the resilient protruding plates, respectively, whereas bumps are protrudingly disposed at the penetrating post and protrudingly exposed from the windows, respectively.

14. A casing device, comprising:
a first casing with a surface having an opening and another surface having a through hole in communication with the opening;
a second casing having a penetrating hole in communication with the through hole, wherein the second casing and the first casing can be closed; and
the insertion structure of claim 13 , wherein the tamperproof element is penetratingly disposed in the through hole and the penetrating hole, with the barb-like protruding portions abutting against a bottom of the opening, wherein the plurality of resilient protruding plates and an engagement structure disposed inside the penetrating hole are engaged with each other such that a portion of the first casing and a portion of the second casing are clamped between the barb-like protruding portions and the plurality of resilient protruding plates.

15. The casing device of claim 14 , wherein the engagement structure comprises an internal thread disposed on an inner wall of the penetrating hole, wherein the plurality of resilient protruding plates and the internal thread are engaged with each other.

16. The casing device of claim 15 , wherein the leaf springs are in a number of plurality and vertically spaced apart, wherein terminal ends of two adjacent ones of the resilient protruding plates vertically spaced apart are separated by a distance which is a multiple of a pitch of the internal thread.

17. The casing device of claim 14 , wherein the engagement structure comprises a stop ring disposed on an inner wall of the penetrating hole, wherein the plurality of resilient protruding plates and the stop ring are engaged with each other.

18. The casing device of claim 14 , further comprising a through pipe with an outer wall abutting against an inner wall of the penetrating hole, wherein the engagement structure comprises a flange disposed on an inner wall of the through pipe, wherein the plurality of resilient protruding plates and the flange are engaged with each other.

19. The casing device of claim 18 , wherein the outer wall of the through pipe extends to form a sandwiched block sandwiched between the first casing and the second casing.

20. The casing device of claim 14 , wherein an area of the opening is larger than an area of the through hole, thereby allowin
