Abstract

A fixing structure for a casing and a method for manufacturing the same are provided. The fixing structure for a casing includes a hollow-core post, a fixing post, and a screwing element. The hollow-core post extends from the casing. The fixing post comprises a fixing segment. The fixing segment is inserted into the hollow-core post and has an inner screw hole. The screwing element is inserted into the casing and screwed to the inner screw hole. Therefore, the fixing structure is conducive to enhancement of the strength of engagement between the hollow-core post and the fixing post.

First claim

What is claimed is:

1. A fixing structure for a casing, comprising:
a hollow-core post protruding from the casing;
a fixing post comprising a fixing segment and a connecting segment, the fixing segment being disposed in the hollow-core post and having an inner screw hole, and the connecting segment extending from the fixing segment and having a through connection hole with an inner thread, wherein the hollow-core post is integrally formed with the casing and wrapped around the fixing segment by injection molding such that the hollow-core post is adhered to the fixing segment with the inner screw hole in communication with a through hole in the casing;
a screwing element inserted into the through hole of the casing and screwed to the inner screw hole; and
a fastening component screwed to inner thread of the through connection hole.

2. The fixing structure for a casing of claim 1 , wherein a plurality of ribs spaced apart from each other protrude from the hollow-core post radially.

3. The fixing structure for a casing of claim 1 , wherein the connecting segment is exposed by the hollow-core post.

4. The fixing structure for a casing of claim 1 , wherein the screwing element comprises an abutting portion abutting against the casing and a screwing segment extended from the abutting portion, inserted into the casing, and screwed to the inner screw hole.

5. The fixing structure for a casing of claim 1 , wherein the through connection hole and the inner screw hole are in communication with each other.

6. The fixing structure for a casing of claim 1 , further comprising an installation component fastened to the through connection hole by a fastening component and thus fixed to the casing.

7. The fixing structure for a casing of claim 1 , wherein the through connection hole and the inner screw hole are not in communication with each other.

8. The fixing structure for a casing of claim 1 , wherein the fixing post does not have an exterior thread.

9. The fixing structure for a casing of claim 1 , wherein the through hole in the casing is formed by the injection molding.

10. A method for manufacturing a casing comprising the fixing structure of claim 1 , comprising the steps of:
a) providing the fixing post and forming the inner screw hole in the fixing post;
b) providing a mold and disposing the fixing post in the mold; and
c) introducing a liquid high-density glass fiber material into the mold and forming integrally the casing and the hollow-core post in the mold, wherein the hollow-core post encloses the fixing segment of the fixing post, and the through hole is formed in the casing in communication with the inner screw hole.

11. The method for manufacturing the casing of claim 10 , further comprising the step of providing the screwing element inserted into the through hole and screwed to the inner screw hole.

12. The method for manufacturing the casing of claim 11 , wherein the screwing element comprises an abutting portion abutting against the casing and a screwing segment extended from the abutting portion, inserted into the through hole, and screwed to the inner screw hole.

13. The method for manufacturing the casing of claim 10 , wherein a plurality of ribs spaced apart from each other protrude from the hollow-core post radially.

14. The method for manufacturing the casing of claim 10 , wherein the inner thread is formed in the through connection hole.
