[0039] Reference Figure 1-4 This utility model provides a PCB assembly fixture, including a first limiting component 1, a second limiting component 2, and a connecting component 3. The first limiting component 1 and the second limiting component 2 can both be slidably connected to the connecting component 3. The first limiting component 1 and the second limiting component 2 slide relative to each other, which can clamp the PCB circuit board and place the PCB circuit board into the chassis.

[0040] The connecting component 3 includes a fixing plate 31 and a connecting plate 32. The connecting plate 32 is fixed to the lower side of the fixing plate 31. Limiting grooves 321 are formed on both sides of the connecting plate 32. A protruding structure that cooperates with the limiting grooves 321 can be provided on the external chassis to determine the position of the PCB assembly fixture. The fixing plate 31 can be used to connect the first limiting component 1 and the second limiting component 2. It should be noted that the position of the limiting grooves 321 is not fixed and can be changed according to the position of the protruding structure on the chassis, as long as it can cooperate with the protruding structure to perform a limiting function.

[0041] Two first uprights 311 are fixed to both sides of the upper surface of the fixing plate 31. The two first uprights 311 can cooperate with the first limiting component 1 to guide the sliding of the first limiting component 1. Two second uprights 312 are fixed to the middle of the upper surface of the fixing plate 31. The second uprights 312 can cooperate with the second limiting component 2. A rotating shaft 313 is also fixed to the fixing plate 31, which can be connected to the first limiting component 1 and the second limiting component 2 for adjusting the position of the first limiting component 1 and the second limiting component 2.

[0042] The first limiting component 1 includes a first sliding plate 11 and a first clamping plate 12. The first sliding plate 11 and the first clamping plate 12 are fixed to each other. The surface of the first sliding plate 11 is provided with a plurality of first waist-shaped grooves 111. The first upright 311 is slidably connected in the first waist-shaped grooves 111, so that the first sliding plate 11 is slidably connected above the connecting plate 32.

[0043] The second limiting component 2 includes a second sliding plate 21 and a second clamping plate 22, which are fixed to each other. The second sliding plate 21 is located above the first sliding plate 11. Two grooves 112 are provided on one side of the first sliding plate 11, with one end of each groove extending to one side of the first sliding plate 11. Two connecting strips 212 are fixed to the lower side of the second sliding plate 21 and are inserted into the grooves 112, so that the first limiting component 1 and the second limiting component 2 can cooperate with each other to improve movement stability.

[0044] The connecting strip 212 has a second waist-shaped groove 211, and the second upright 312 is slidably connected to the second waist-shaped groove 211, so that the connecting strip 212 and the second sliding plate 21 can be slidably connected to the fixed plate 31. The first waist-shaped groove 111 and the second waist-shaped groove 211 extend in the same direction, so that the first limiting component 1 and the second limiting component 2 can slide in a direction that moves closer to or further away from each other.

[0045] The first clamping plate 12 and the second clamping plate 22 are located on opposite sides of the connecting plate 32. A plurality of first spring posts 13 are fixed on one side of the first clamping plate 12, and a plurality of second spring posts 23 are fixed on one side of the second clamping plate 22. The first spring posts 13 and the second spring posts 23 are located on the side of the first clamping plate 12 and the second clamping plate 22 that are close to each other.

[0046] During operation, the PCB board can be placed on a workbench or table first. The PCB board assembly fixture of this application is then placed close to the PCB board from top to bottom. The first clamping plate 12 and the second clamping plate 22 are moved away from each other. The PCB board is then placed between the first clamping plate 12 and the second clamping plate 22, close to the first clamping plate 12 and the second clamping plate 22. The first spring post 13 and the second spring post 23 can move closer to each other to press against the PCB board. Alternatively, positioning grooves can be set on the side of the PCB board corresponding to the positions of the first spring post 13 and the second spring post 23. The first spring post 13 and the second spring post 23 are inserted into the positioning grooves, and the PCB board and the PCB board assembly fixture are installed together. The PCB assembly fixture, along with the PCB board, extends into the chassis through the mounting port. A protruding structure pre-installed in the chassis and engaging with the limiting groove 321 positions the PCB assembly fixture within the chassis, thus moving the PCB board to that location. This facilitates subsequent assembly of the PCB board, solving the problem of inconvenient manual access to the chassis for PCB installation and improving PCB installation efficiency. It should be noted that the protruding structure engaging with the limiting groove 321 is a plug-in structure using the existing protrusion-recessed groove 112; its specific structure will not be described further in this application.

[0047] In one embodiment, a first rectangular groove 113 is formed on the surface of the first sliding plate 11, and a first disk 14 is disposed within the first rectangular groove 113. The first disk 14 is fixed to a rotating shaft 313 on the fixed plate 31. Rotation of the rotating shaft 313 can drive the first disk 14 to rotate. The diameter of the first disk 14 is the same as the width of the first rectangular groove 113. The first disk 14 is divided into a first A region 141 and a first B region 142. The first A region 141 is located near the first clamping plate 12, and the first B region 142 is located near the second clamping plate 22. The rotating shaft 313 is fixed to the first A region 141, so that the first disk 14 can eccentrically swing as the first rotating shaft 313 rotates. The rotation of the rotating shaft 313 can cause the first disk 14 to swing, and the first disk 14 swings and contacts the side of the first rectangular groove 113, thereby driving the first sliding plate 11 to slide.

[0048] The surface of the second sliding plate 21 is provided with a second rectangular groove 213, and a second disk 24 is provided in the second rectangular groove 213. The second disk 24 is fixed to the rotating shaft 313. The diameter of the second disk 24 is the same as the width of the second rectangular groove 213. The second disk 24 is divided into a second A area 241 and a second B area 242. The second A area 241 is close to the first clamping plate 12, and the second B area 242 is close to the second clamping plate 22. The rotating shaft 313 is fixed to the second B area 242.

[0049] Since the rotating shaft 313 is fixed in different half of the first disk 14 and the second disk 24, the rotating shaft 313 can drive the first disk 14 and the second disk 24 to swing eccentrically in different directions, thereby causing the first sliding plate 11 and the second sliding plate 21 to slide in different directions, thereby causing the first clamping plate 12 and the second clamping plate 22 to move closer or further away from each other.

[0050] As one embodiment, a turntable 4 is fixed to the upper end of the rotating shaft 313. The turntable 4 and the rotating shaft 313 are coaxially arranged. A handle 41 is fixed to one side of the turntable 4. Rotating the handle 41 can drive the rotating shaft 313, thereby adjusting the positional relationship between the first clamping plate 12 and the second clamping plate 22.

[0051] A locking rod 25 is fixed on the upper side of the second sliding plate 21. The locking rod 25 is located in the middle of the second sliding plate 21 and is set on the side close to the first clamping plate 12. The handle 41 can abut against the locking rod 25, and the locking rod 25 can restrict the position of the handle 41.

[0052] As one embodiment, a circular groove 26 is provided on the second sliding plate 21, and a vertical groove 42 is provided on the handle 41. The vertical groove 42 and the circular groove 26 can be coaxially arranged. A first positioning pin 261 can be inserted into the vertical groove 42 and the circular groove 26 to prevent the handle 41 from rotating and to determine the position of the handle 41 and the second sliding plate 21.

[0053] The surface of the first sliding plate 11 has a through groove 15, and the fixing plate 31 has a slot 314. The slot 314 and the through groove 15 can be coaxially arranged, and a second positioning pin 315 can be inserted into both. The first positioning pin 261 and the second positioning pin 315 can fix the position of the first clamping plate 12 and the second clamping plate 22, preventing them from moving freely. In use, with the first spring post 13 and the second spring post 23 restricting the PCB board, the slot 314 and the through groove 15 are connected, and the vertical groove 42 and the circular groove 26 are connected. At this time, inserting the first positioning pin 261 and the second positioning pin 315 can stably clamp the PCB board.

[0054] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0055] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions that those skilled in the art can make regarding the above details will be included within the scope of the claims of this utility model.
