Abstract

Fixing apparatus includes a pressing cover, a base facing to the pressing cover, a movable arm coupled between the pressing cover and the base, a chassis, an elastic element located between the pressing cover and the base, and a positioning shaft extending through the chassis, the base, and the elastic element to insert to the pressing cover. The positioning shaft forms a supporting portion away from the pressing cover. The chassis defines a first slot. When the chassis moves towards the pressing cover, the movable arm is pressed to open outwardly, the elastic element is compressed to press the chassis away from the pressing cover, the positioning portion moves towards the first slot until locks in the first slot. The fixing apparatus can press the device to the plank to fix the device on the plank.

First claim

What is claimed is:

1. A fixing apparatus, comprising:
a pressing cover;
a base facing the pressing cover;
a movable arm connecting between the pressing cover and the base;
a chassis connecting with base and defining a first slot and an adjacent slot;
an elastic element located between the pressing cover and the chassis; and
a supporting shaft extending through the chassis, the base and the elastic element to fix to the pressing cover, the supporting shaft comprising a positioning portion located one end of the supporting shaft; wherein the positioning portion of the supporting shaft moves toward the first slot to insert into the first slot when the chassis moves toward the pressing cover to position the chassis on the pressing cover, the elastic element is pressed to provide an elastic force for pushing the chassis away from the pressing cover, when the positioning portion is switched to be received in the second slot, the movable arm closes with force of the elastic element, the chassis and the pressing cover are spaced apart.

2. The fixing apparatus of the claim 1 , wherein the chassis is configured to move toward the pressing cover, the base and the supporting shaft is configured to rotate relative to the chassis.

3. The fixing apparatus of the claim 2 , wherein the second slot is with a depth less than the depth of the first slot.

4. The fixing apparatus of the claim 3 , wherein the first slot and the second slot are connected by a first sloped surface, the positioning portion of the supporting shaft defines a second sloped surface, the cooperating between the second sloped surface and the first sloped surface helps the supporting shaft rotate relative to the chassis after the positioning portion moves out of the second slot.

5. The fixing apparatus of the claim 4 , wherein the pressing cover comprises a first guiding portion, the chassis comprises a second guiding portion facing to the first guiding portion, the second guiding portion and the first guiding portion resist to each other to make the pressing cover rotate relative to the chassis when the chassis moves toward the pressing cover.

6. The fixing apparatus of the claim 5 , wherein the chassis comprises a supporting board and an empty pillar formed on the supporting board, the first guiding portion and the first slot are located on two ends of the empty pillar, respectively.

7. The fixing apparatus of the claim 5 , wherein the first guiding portion comprises a plurality of first teeth and a plurality of the first grooves located between each two adjacent first teeth, the second guiding portion comprises a plurality of second teeth and a plurality of the second grooves located between each two adjacent second teeth, wherein the second tooth is misaligned with the first groove.

8. The fixing apparatus of the claim 7 , wherein the first teeth has a biasing force to second teeth to make the pressing cover rotate relative to the chassis.

9. The fixing apparatus of the claim 8 , wherein the first tooth connects with second tooth before the first sloped surface connects with the second sloped surface.

10. The fixing apparatus of the claim 1 , wherein the movable arm comprises a first connecting pole connecting with the pressing cover and a second connecting pole connecting with the base and the first connecting pole, when the chassis moves toward the pressing cover, the second connecting pole closes to the first connecting pole.

11. A module comprising:
a plank, a device positioned on the plank, and a fixing apparatus, the device is mounted on the plank with the fixing apparatus, wherein the fixing apparatus comprising:
a pressing cover;
a base facing the pressing cover;
a movable arm connecting between the pressing cover and the base;
a chassis connecting with base and defining a first slot and an adjacent second slot;
an elastic element located between the pressing cover and the chassis; and
a supporting shaft extending through the chassis, the base and the elastic element to fix to the pressing cover, the supporting shaft comprising a positioning portion located one end of the supporting shaft; wherein the positioning portion of the supporting shaft moves toward the first slot to insert into the first slot when the chassis moves toward the pressing cover to position the chassis on the pressing cover, the elastic element is pressed to provide an elastic force for pushing the chassis away from the pressing cover, the movable arm opens; when the positioning portion is switched to be received in the second slot, the movable arm closes with force of the elastic element, the chassis and the pressing cover are spaced apart.

12. The fixing apparatus of the claim 11 , wherein the chassis is configured to move toward the pressing cover, the base and the supporting shaft is configured to rotate relative to the chassis.

13. The fixing apparatus of the claim 11 , wherein the second slot is with a depth less than the depth of the first slot.

14. The fixing apparatus of the claim 13 , wherein the first slot and the second slot are connected by a first sloped surface, the positioning portion of the supporting shaft defines a second sloped surface, the cooperating between the second sloped surface and the first sloped surface helps the supporting shaft rotate relative to the chassis after the positioning portion moves out of the second slot.

15. The fixing apparatus of the claim 14 , wherein the pressing cover comprises a first guiding portion, the chassis comprises a second guiding portion facing to the first guiding portion, the second guiding portion and the first guiding portion resist to each other to make the pressing cover rotate relative to the chassis when the chassis moves toward the pressing cover.

16. The fixing apparatus of the claim 15 , wherein the chassis comprises a supporting board and an empty pillar formed on the supporting board, the first guiding portion and the first slot are located on two ends of the empty pillar, respectively.

17. The fixing apparatus of the claim 15 , wherein the first guiding portion comprises a plurality of first teeth and a plurality of the first grooves located between each two adjacent first teeth, the second guiding portion comprises a plurality of second teeth and a plurality of the second grooves located between each two adjacent second teeth, wherein the second tooth is misaligned with the first groove.

18. The fixing apparatus of the claim 17 , wherein the first teeth has a biasing force to second teeth to make the pressing cover rotate relative to the chassis.

19. The fixing apparatus of the claim 18 , wherein the first tooth connects with second tooth before the first sloped surface connects with the second sloped surface.

20. The fixing apparatus of the claim 11 , wherein the movable arm comprises a first connecting pole connecting with the pressing cover and a second connecting pole connecting with the base and the first connecting pole, when the chassis moves toward the pressing cover, the second connecting pole closes to the first connecting pole.

21. A fixing apparatus, comprising:
