It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0056] The present invention is a fixing device that can be installed on an electronic device to assist in fixing the electronic device on a guide rail in a chassis. Please refer to Figure 1 and Figure 2 to illustrate the structure of the fixing device 1. The fixing device 1 includes a base 10, a movable hook seat 20, a driving module 30, and an elastic member 40. The movable hook seat 20 is disposed on the base 10, and the driving module 30 is connected to the movable hook seat 20 to drive the movable hook seat 20 to move relative to the base 10 along the first direction D1. When the driving module 30 does not apply force to the movable hook seat 20, the elastic force of the elastic member 40 can be used to reset the movable hook seat 20.

[0057] Please continue to refer to Figure 1 and Figure 2 to illustrate in detail the structure of the fixing device 1. The structure of the base 10 includes a first plate body 12, two first hooks 14, 14', and a first fixing plate 16. A chute 122 is provided near the top of the center of the first plate body 12, and the chute 122 extends along the first direction D1. The first plate body 12 further includes a plurality of fixing portions 124. The fixing portions 124 are through holes, and locking components, such as screws and other components, can be provided to pass through the first plate body 12 along the third direction D3 to fix the first plate body 12 on the electronic device. The two first hooks 14, 14' are respectively disposed on both sides of the first plate body 12 along the second direction D2, and the two first hooks 14, 14' are perpendicular to the first plate body 12 and extend along the third direction D3. The first direction D1 is perpendicular to the second direction D2, and the third direction is perpendicular to the first direction D1. The first fixing plate 16 is disposed on the first plate body 12 and between the two first hooks 14, 14'. The first fixing plate 16 is perpendicular to the first plate body 12 and extends along the third direction D3.

[0058] The movable hook seat 20 is disposed on the base 10 and located between the two first hooks 14, 14'. The structure of the movable hook seat 20 includes a second plate body 22, a second fixing plate 24, and two second hooks 26, 26'. An opening groove 222 extending along the first direction D1 is provided on the second plate body 22. When the movable hook seat 20 is disposed on the base 10, the first fixing plate 16 vertically disposed on the first plate body 12 can pass through the opening groove 222 in the third direction D3. The second fixing plate 24 is vertically disposed on the second plate body 22 and extends along the third direction D3. The second fixing plate 24 is adjacent to the opening groove 222 in the first direction D1, and the second fixing plate 24 corresponds to the first fixing plate 16 passing through the opening groove 222 in the first direction D1. The two second hooks 26, 26' are respectively disposed on both sides of the second plate body 22 in the second direction D2 and are perpendicular to the second plate body 22 and extend along the third direction D3. In this embodiment, the hook concave portions 140, 140' of the first hooks 14, 14' are disposed opposite to the hook concave portions 260, 260' of the second hooks 26, 26' in the first direction D1. Through the relative arrangement of the hook concave portions 140, 140' of the opposite first hooks 14, 14' and the hook concave portions 260, 260' of the second hooks 26, 26', a clamping portion can be formed to clamp on the guide rail, thereby mounting the electronic device on the guide rail.

[0059] The driving module 30 is connected to the movable hook seat 20 to drive the movable hook seat 20 to move relative to the base 10 along the first direction D1, thereby pulling apart the distances between the first hooks 14, 14' and the second hooks 26, 26', so as to facilitate the operation of clamping the fixing device 1 onto the guide rail. In this embodiment, the structure of the driving module 30 includes a first connecting rod 32, a second connecting rod 34, a first shaft core 36, a second shaft core 38, and a third shaft core 39. The first connecting rod 32 includes a first end 320 and a second end 322. The second connecting rod 34 includes a connecting portion 340, a handle portion 342, and an axis portion 344. The axis portion 344 connects the connecting portion 340 and the handle portion 342, and the connecting portion 340 is arranged to extend obliquely relative to the handle portion 342, forming a shape similar to a V. The first shaft core 36 penetrates the first end 320 of the first connecting rod 32, the second plate body 22, and the sliding groove 122 along the third direction D3, and a limiting member 360 is provided at one end of the first shaft core 36 passing out of the sliding groove 122 to limit the movement of the first shaft core 36 in the sliding groove 122. Specifically, the diameter of the first shaft core 36 is smaller than the width of the sliding groove 122, and the diameter of the limiting member 360 is a circular plate body larger than the width of the sliding groove 122. Therefore, the first shaft core 36 can move in the sliding groove 122, and the setting of the limiting member 360 can limit the range of the first shaft core 36 leaving the sliding groove 122 to prevent the first shaft core 36 from detaching from the sliding groove 122. The second shaft core 38 is fixed at a position near the side of the first plate body 12 along the third direction D3 and penetrates the second end 322 of the first connecting rod 32 and the connecting portion 340. The third shaft core 39 is fixed at a position near the bottom of the first plate body 12 along the third direction D3 and penetrates the axis portion 344.

[0060] The elastic member 40 is arranged between the first fixing plate 16 and the second fixing plate 24 along the first direction D1. In this embodiment, the elastic member 40 is a spring. The elastic member 40 provides elastic force to reset the movable hook seat 20. A first fixing protrusion 160 is provided on one side of the first fixing plate 16 corresponding to the second fixing plate 24 along the first direction D1, and the first fixing protrusion 160 protrudes towards the second fixing plate 24 along the first direction D1. A second fixing protrusion 240 is provided on one side of the second fixing plate 24 corresponding to the first fixing plate 16 along the first direction D1, and the second fixing protrusion 240 protrudes towards the first fixing plate 16 along the first direction D1. One end of the elastic member 40 is fixed by the first fixing protrusion 160, and the other end of the elastic member 40 is fixed by the second fixing protrusion 240. Through the above structure, the elastic member 40 can be fixed between the first fixing plate 16 and the second fixing plate 24.

[0061] After describing the structure of the fixing device 1 of the present invention, please then refer to Figures 3 to 6 to illustrate the implementation manner of the use of the fixing device 1. First, please refer to Figure 3, a locking component, such as a screw, can be used to pass through the fixing portion 124 of the first plate body 12 to fix the fixing device 1 on the electronic device to be installed on the guide rail. Then, please refer to Figure 4 and Figure 5 , the user operates the handle portion 342 to move, driving the connecting portion 340 to move to drive the first link 32, so that the first link 32 pulls to drive the movable hook seat 20. Since the first link 32 is restricted in the chute 122, and at the same time the first fixing plate 16 is also restricted by the slot 222 to the movable position, the movable hook seat 20 can only move along the first direction D1 relative to the base 10 towards the bottom of the base 10. At the same time, when the movable hook seat 20 moves, the second fixing plate 24 will also squeeze the elastic member 40 together. At the same time, the distances between the first hooks 14, 14' and the second hooks 26, 26' are also pulled apart due to the movement of the movable hook seat 20, so as to facilitate the operation of clamping on the guide rail 50.

[0062] Please refer to Figure 6 , when the user adjusts the electronic device to the desired position, release the handle portion 342. At this time, the elastic force of the elastic member 40 can be used to move the movable hook seat 20 towards the top of the base 10 to complete the reset, shortening the distances between the first hooks 14, 14' and the second hooks 26, 26', so as to achieve the effect of clamping on the guide rail 50.

[0063] In summary, the fixing device of the present invention is simple to operate, convenient for installation and disassembly, and has a good fixing effect.

[0064] In summary, the present invention meets the requirements of an invention patent, and a patent application is filed in accordance with the law. However, the above are only the preferred embodiments of the present invention, and the scope of the present invention is not limited to the described embodiments.
