[0004] When using the above technology, the following technical problems were found in the existing technology: Although the circuit board clamping device can achieve stable horizontal fixation, its structural design has significant operational limitations. The clamped circuit board cannot be flipped at multiple angles. This defect causes the staff to repeatedly disassemble and assemble the circuit board during the maintenance process, making the operation cumbersome and time-consuming, thereby reducing maintenance efficiency.

[0008] The clamping assembly includes a placement slot. The placement slot is provided on the inner side of the placement frame. Clamping plates a and b are symmetrically arranged on the inner side of the placement slot. Clamping plate a is fixedly connected to the placement frame. A rotating shaft is rotatably connected to the middle of the end of clamping plate b away from clamping plate a.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0027] like Figure 1 - Figure 5As shown, a clamping device for aluminum-based circuit boards of security cameras includes a base 101. A support frame 102 is fixedly connected to the upper end of the base 101, and a support plate 103 is fixedly connected to the upper end of the support frame 102. A placement rack 104 is provided at the end of the support plate 103. A through hole 105 and an equal row of serrated grooves 106 are formed on the inner side of the support plate 103. The through hole 105 and the equal row of serrated grooves 106 are interconnected. The placement rack 104 is located near the end of the support plate 103. A rotating rod 107 is fixedly connected to the middle of the frame. The rotating rod 107 is rotatably connected to the through hole 105. A rotating ring 108 is provided on the outer side of the rotating rod 107. A serrated ring 109 is fixedly connected to the end of the rotating ring 108. The rotating ring 108 is slidably engaged with the serrated groove 106. A limiting component is provided between the rotating ring 108 and the rotating rod 107. A clamping component is provided on the inner side of the placement frame 104. A fixing component is provided at the lower end of the base 101.

[0028] The limiting component includes a limiting block a201. Multiple sets of limiting blocks a201 are fixedly connected to the inner side of the rotating ring 108. Multiple sets of limiting grooves a202 are opened on the inner side of the rotating rod 107. The limiting block a201 is located inside the limiting groove a202 and is slidably connected to the limiting groove a202. A grip block 204 is fixedly connected to one end of the rotating rod 107 away from the placement frame 104. A spring 203 is provided on the outer side of the rotating rod 107 and between the rotating ring 108 and the grip block 204. The two ends of the spring 203 are fixedly connected to the rotating ring 108 and the grip block 204, respectively.

[0029] The two ends of the rotating ring 108 are symmetrically fixedly connected with pull rods 701.

[0030] During operation, the device is fixed to the table using a fixing component, and then the camera's aluminum-based circuit board is clamped using a clamping component. The operator then repairs the circuit board. When the operator needs to rotate the board, pulling the lever 701 moves the rotating ring 108 towards the grip block 204, causing the rotating ring 108 to disengage the serrated ring 109 from the serrated groove 106. Then, rotating the rotating rod 107 causes the placement frame 104 and the circuit board inside it to rotate, thus rotating the circuit board to the appropriate position. The operator slides the serrated ring 109 to the inside of the serrated groove 106, and the elasticity of the spring 203 makes the serrated groove 106 and the serrated ring 109 lock into place stably. Then, the rotation of the rotating rod 107 is restricted by the limiting block a201 and the limiting groove a202. The serrated ring 109 separates from the serrated groove 106, allowing the operator to rotate the placement frame 104 to drive the circuit board to rotate at multiple angles. This eliminates the need for repeated disassembly and reassembly of the circuit board during maintenance, thus improving maintenance efficiency. Example

[0031] like Figure 1 - Figure 4 As shown, the clamping assembly includes a placement groove 301. The placement frame 104 has a placement groove 301 on its inner side. A clamping plate a302 and a clamping plate b303 are symmetrically arranged on the inner side of the placement groove 301. The clamping plate a302 is fixedly connected to the placement frame 104. A rotating shaft 304 is rotatably connected to the middle of the end of the clamping plate b303 away from the clamping plate a302. A threaded rod a305 is fixedly connected to the end of the rotating shaft 304 away from the clamping plate a302. The threaded rod a305 is threadedly connected to the placement frame 104.

[0032] The clamping plate b303 is symmetrically fixedly connected to the two ends of the limiting block b401. The inner side of the placement frame 104 is provided with a limiting groove b402. The limiting block b401 is located inside the limiting groove b402 and is slidably connected to the limiting groove b402.

[0033] Silicone pads a601 and b602 are fixedly connected to the ends of clamping plates a302 and b303 respectively, which increase the friction when the placement groove 301 and clamping plate a302 hold the circuit board.

[0034] During operation, the circuit board is placed between the placement slot 301 and the clamping plate b303. Then, the threaded rod a305 is rotated, and the threaded rod a305 is threadedly connected to the placement frame 104, thereby driving the clamping plate b303 to move laterally, thereby reducing the distance between the clamping plate a302 and the clamping plate b303, so that the device can clamp circuit boards of different sizes. Example

[0035] like Figure 1 - Figure 5 As shown, the fixing assembly includes a clamping plate c501. The lower end of the base 101 is provided with the clamping plate c501. A threaded rod b502 is rotatably connected to the inner side of the base 101. The threaded rod b502 is threadedly connected to the clamping plate c501. A guide rod 503 is symmetrically fixedly connected to the lower end of the base 101. The guide rod 503 is slidably connected to the clamping plate c501. Limiting blocks c504 are fixedly connected to the lower ends of both the threaded rod b502 and the guide rod 503.

[0036] During operation, the base 101 is placed on the edge of the tabletop, so that the tabletop is located between the base 101 and the clamping plate c501. Then, the threaded rod b502 is rotated, and the threaded rod b502 is threadedly connected to the clamping plate c501. The clamping plate c501 is limited by two guide rods 503, thereby shortening the distance between the clamping plate c501 and the base 101, so that the device can clamp tables of different thicknesses.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
