Abstract

A clamping structure includes an object, a clamping component and an elastic component. The object has a hole and a containing space, wherein the containing space is connected to the hole. The clamping component includes a pillar, a bump and a head portion, wherein the bump and the head portion are connected to the pillar, and the pillar is adapted to be inserted into the hole and rotated such that the bump moves to the containing space. When the bump is located in the containing space, the elastic component is compressed between the object and the head portion, and the bump is positioned at the containing space by elastic force of the elastic component, such that the clamping component is fastened to the object.

First claim

What is claimed is:

1. A clamping structure, adapted to an electronic device, the clamping structure comprising:
an object having a hole and a containing space, wherein the containing space is connected to the hole;
a clamping component comprising a pillar, a bump and a head portion, wherein the bump and the head portion are connected to the pillar, and the pillar is adapted to be inserted into the hole and rotated such that the bump moves to the containing space; and
an elastic component, wherein when the bump is located in the containing space, the elastic component is compressed between the object and the head portion, and the bump is positioned at the containing space by elastic force of the elastic component, such that the clamping component is fastened to the object.

2. The clamping structure according to claim 1 , wherein the object has a containing recessed portion, and the elastic component is adapted to be contained in the containing recessed portion.

3. The clamping structure according to claim 2 , wherein the object has a position-limiting protruding portion, the position-limiting protruding portion is located in the containing recessed portion, and the elastic component is position-limited between an inner wall of the containing recessed portion and the position-limiting protruding portion.

4. The clamping structure according to claim 3 , wherein a thickness of the elastic component is greater than a thickness of the position-limiting protruding portion.

5. The clamping structure according to claim 3 , wherein a thickness of the elastic component is smaller than a thickness of the position-limiting protruding portion, the clamping component has a protruding edge, the protruding edge and the pillar are connected to the same side of the head portion, and when the clamping component is fastened to the object, the protruding edge extends between the inner wall of the containing recessed portion and the position-limiting protruding portion and compresses the elastic component.

6. The clamping structure according to claim 1 , wherein the object has an upper surface and a guide groove, the pillar is adapted to be inserted into the hole from the upper surface, the guide groove extends from the upper surface to the containing space, and the bump is adapted to move to the containing space by guidance of the guide groove.

7. The clamping structure according to claim 6 , wherein the guide groove comprises a first section and a second section, the first section is connected between the upper surface and the second section and extends along a direction perpendicular to the upper surface, and the second section is connected between the first section and the containing space and extends along a direction parallel to the upper surface.

8. The clamping structure according to claim 6 , wherein the guide groove extends to the containing space along a direction tilted with respect to the upper surface.

9. The clamping structure according to claim 6 , wherein the bump has at least one inclined surface, and the inclined surface is adapted to move along inner walls of the guide groove.

10. The clamping structure according to claim 1 , wherein the elastic component has a ring shape and surrounds the pillar.

11. The clamping structure according to claim 10 , wherein the pillar has a position-limiting section, an outer diameter of the position-limiting section is smaller than outer diameters of the other sections of the pillar, and the elastic component is position-limited to the position-limiting section.

12. The clamping structure according to claim 1 , wherein the elastic component is a waterproof elastic component.

13. The clamping structure according to claim 1 , wherein the containing space has a protrusion therein, and when the bump is located in the containing space, the protrusion prevents the bump from leaving from the containing space.

14. The clamping structure according to claim 1 , wherein the elastic component is fixed to the pillar, and when the pillar is inserted into the hole, the elastic component moves onto the object with movement of the pillar.

15. The clamping structure according to claim 1 , wherein the elastic component is adapted to be placed on the object, and when the pillar is inserted into the hole, the clamping component compresses the elastic component on the object.

16. The clamping structure according to claim 1 , wherein the clamping component is adapted to be inserted into the hole along a direction parallel to a central axis of the pillar, and rotated around the central axis of the pillar to drive the bump to move to the containing space.

17. The clamping structure according to claim 1 , wherein the object comprises a first component and a second component, the first component has a first assembly hole, the second component has a second assembly hole, the containing space is located at the second component, the first component leans against the second component such that the first assembly hole and the second assembly hole are aligned with each other to form the hole, and when the clamping component is fastened to the object, the elastic component is compressed between the first component and the head portion, and the head portion prevents the first component from being separated from the second component.

18. The clamping structure according to claim 1 , wherein the head portion has a sawtooth structure, and the sawtooth structure is adapted to receive a force to drive the clamping component to rotate.

19. An electronic device, comprising:
a casing having a hole and a containing space, wherein the containing space is connected to the hole;
a clamping component comprising a pillar, a bump and a head portion, wherein the bump and the head portion are connected to the pillar, and the pillar is adapted to be inserted into the hole and rotated such that the bump moves to the containing space; and
an elastic component, wherein when the bump is located in the containing space, the elastic component is compressed between the casing and the head portion, and the bump is positioned at the containing space by elastic force of the elastic component, such that the clamping component is fastened to the casing, wherein the elastic component is a waterproof elastic component.

20. The electronic device according to claim 19 , wherein the elastic component is adapted to be placed on the casing, and when the pillar is inserted into the hole, the clamping component compresses the elastic component on the casing, wherein the casing has a containing recessed portion, and the elastic component is adapted to be contained in the containing recessed portion.

21. The electronic device according to claim 20 , wherein the casing has a position-limiting protruding portion, the position-limiting protruding portion is located in the containing recessed portion, and the elastic component is position-limited between an inner wall of the containing recessed portion and the position-limiting protruding portion.

22. The electronic device according to claim 21 , wherein a thickness of the elastic component is greater than a thickness of the position-limiting protruding portion.
