Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to an LED circuit board fixing mechanism. Background Technology

[0002] In the assembly and maintenance of electronic equipment, communication cabinets, and industrial control systems, circuit boards are often core modules that require frequent installation, replacement, or debugging. Traditional fixing methods generally use screws to fasten the circuit board, which involves attaching the circuit board to the mounting posts of the chassis or backplate using multiple screws. When the circuit board experiences a short circuit or requires maintenance, the screws need to be removed with a screwdriver. If the removed screws are not properly stored and are lost, it will be impossible to re-fix the circuit board. Therefore, this solution proposes an LED circuit board fixing mechanism to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an LED circuit board fixing mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an LED circuit board fixing mechanism, applied to the circuit board body, comprising: A fixing frame is fitted onto the outer wall of the circuit board body, and fixing bolts are provided at all four corners of the fixing frame; A pressing plate is disposed on the top of the fixed frame and is used to prevent the circuit board body from moving. A limiting component is disposed at the connection between the fixed frame and the pressing plate; A locking component is disposed on the top of the pressing plate and is used to fix the position of the pressing plate.

[0005] Preferably, the limiting component includes a fixing block fixedly connected to the top of the fixing frame, the bottom of the fixing block having a limiting groove, and the pressing plate being inserted into the limiting groove.

[0006] Preferably, a limiting groove is formed on the inner wall of the bottom end of the limiting groove, and a limiting rod is fixedly connected to the bottom end of the pressing plate, the limiting rod being inserted into the inside of the limiting groove.

[0007] Preferably, the locking component includes a positioning slot on the top of the pressing plate, a storage slot on the inner wall of the top of the limiting slot, and a positioning block interlaced between the storage slot and the positioning slot.

[0008] Preferably, the top of the positioning block is provided with a threaded rod, and a rotating block is fixedly connected to the top end of the threaded rod.

[0009] Preferably, the inner wall of the top of the storage slot is provided with a threaded hole, and the threaded rod is inserted into the inside of the threaded hole.

[0010] Preferably, a fixed bearing is inserted and connected to the top of the positioning block, and the fixed bearing is sleeved on the bottom of the threaded rod.

[0011] The technical effects and advantages of this utility model are as follows: This invention utilizes a design incorporating a fixed frame, a pressing plate, a limiting component, and a locking component. During use, the fixed frame is first secured in the desired position. When the circuit board body needs to be fixed, the pressing plate is rotated to the top of the circuit board body. Finally, the locking component secures the pressing plate. The pressing of the pressing plate fixes the circuit board body in place. This allows for easy disassembly and installation of the circuit board body during maintenance by simply rotating the pressing plate, preventing situations where components used to fix the circuit board body may be lost and prevent proper fixation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-4Shown: Example 1: An LED circuit board fixing mechanism, applied to the circuit board body 1, includes: Fixing frame 2 is fitted onto the outer wall of circuit board body 1, and fixing bolts 3 are provided at the four corners of fixing frame 2; Press plate 4 is set on the top of the fixed frame 2 and is used to block the movement of the circuit board body 1; Restriction component 5 is located at the connection between the fixed frame 2 and the pressing plate 4; Locking component 6 is located on top of the pressing plate 4 and is used to fix the position of the pressing plate 4.

[0019] It should be noted that the circuit board body 1 is an LED circuit board, which is the core substrate that carries and connects LED beads, and provides them with stable current and signal control through precision wiring to realize the light-emitting function; the fixing frame 2 is fixed in the required position by fixing bolts 3; in use, the fixing frame 2 is fixed in the required position first, and when it is necessary to fix the position of the circuit board body 1, the pressing plate 4 is rotated so that the pressing plate 4 rotates to the top of the circuit board body 1, and finally the position of the pressing plate 4 is fixed by the locking component 6, and the position of the circuit board body 1 is fixed by pressing the pressing plate 4.

[0020] Specifically, the limiting component 5 includes a fixing block 501 fixedly connected to the top of the fixing frame 2. The bottom of the fixing block 501 is provided with a limiting groove 502. The pressing plate 4 is inserted into the inside of the limiting groove 502. The inner wall of the bottom end of the limiting groove 502 is provided with a limiting groove 504. The bottom end of the pressing plate 4 is fixedly connected with a limiting rod 503, which is inserted into the inside of the limiting groove 504.

[0021] It should be noted that the fixed block 501 and the fixed frame 2 are integrally manufactured. The limiting groove 502 is adapted to the pressing plate 4, allowing the pressing plate 4 to move inside the limiting groove 502. The limiting groove 504 is adapted to the limiting rod 503. Both the limiting rod 503 and the limiting groove 504 are cylindrical, allowing the limiting rod 503 to rotate inside the limiting groove 504. Through the obstruction of the limiting groove 504 and the limiting rod 503, the pressing plate 4 cannot move out of the limiting groove 502. In use, the pressing plate 4 can rotate inside the limiting groove 502 with the limiting rod 503 as the center.

[0022] Example 2: Locking component 6, applied to the fixing mechanism in Example 1; Specifically, the locking component 6 includes a positioning square groove 601 formed on the top of the pressing plate 4, a storage groove 604 formed on the inner wall of the top of the limiting groove 502, a positioning block 602 inserted into the storage groove 604 and the positioning square groove 601, a threaded rod 605 formed on the top of the positioning block 602, a rotating block 607 fixedly connected to the top of the threaded rod 605, a threaded hole 606 formed on the inner wall of the top of the storage groove 604, the threaded rod 605 inserted into the inside of the threaded hole 606, a fixed bearing 603 inserted into the top of the positioning block 602, and the fixed bearing 603 sleeved on the bottom of the threaded rod 605.

[0023] It should be noted that the positioning slots 601 and 604 are adapted to the positioning blocks 602. Both the positioning slots 601 and 604, and the positioning blocks 602, are cubical, preventing the positioning blocks 602, which are interlocked within the positioning slots 601 and 604, from rotating. When adjusting the position of the pressing plate 4, the positioning blocks 602 are first removed. After the pressing plate 4 rotates 90 degrees, the positioning blocks 602 are then inserted into the positioning slots 601. The blocking effect of the positioning blocks 602 prevents the pressing plate 4 from rotating. The fixed bearing 603 is an existing ball bearing, used to connect the positioning block 602 and the threaded rod 605 during use. This allows the threaded rod 605 to be fixed to the top of the positioning block 602 without affecting its rotation. The threaded rod 605 passes through the threaded hole 606 and exits the receiving groove 604. The rotating block 607 is fixedly connected to the top of the threaded rod 605. When the positioning block 602 needs to be moved during use, the rotating block 607 drives the threaded rod 605 to move, which in turn moves the positioning block 602.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
