Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a quick-release circuit board fastener. Background Technology

[0002] With the rapid development of electronic technology, the internal structure of electronic devices is becoming increasingly complex. As a core component of electronic devices, circuit boards make circuits miniaturized and more intuitive. They play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Their stability and reliability are crucial to the performance of the equipment.

[0003] Existing electronic devices typically use screws to fix printed circuit boards (PCBs) inside the housing. While screw fixing offers high reliability and positioning accuracy, removing the screws is cumbersome and time-consuming when circuit problems arise requiring repair or replacement, resulting in inefficient PCB repair or replacement. Therefore, a quick-release PCB fastener is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release circuit board fastener to solve the problem that the existing circuit board fasteners use screws for fixing, which makes the disassembly of the circuit board more laborious.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release circuit board fastener, comprising a circuit board and a mounting base, wherein a disassembly and assembly mechanism is provided between the circuit board and the mounting base, and a heat dissipation mechanism is provided on the mounting base; the disassembly and assembly mechanism includes a fixing rod, on which a mounting block is fixedly mounted; a fixing hole adapted to the fixing rod is provided on the circuit board, and an insertion hole corresponding to the fixing hole is provided on the mounting base; the fixing rod passes through the fixing hole and is inserted into the insertion hole; a locking hole is provided on the fixing rod, and a slot corresponding to the locking hole is provided in the insertion hole; a movable cavity is provided in the mounting base, and a sliding plate is slidably connected in the movable cavity; a locking rod is fixedly mounted on one side of the sliding plate, and a connecting rod is fixedly mounted on the other side of the sliding plate; a spring is sleeved on the connecting rod.

[0006] Preferably, the spring is fixedly disposed between the sliding plate and the movable cavity, and the locking rod groove passes through the movable cavity and through the lock hole to engage with the locking groove.

[0007] Preferably, the end of the connecting rod away from the sliding plate slides through the movable cavity and is fixedly connected to the connecting plate. A handle is fixedly provided on one side of the connecting plate. The handle improves the ease of disassembly of the circuit board and makes the circuit board have a quick-release function.

[0008] Preferably, the heat dissipation mechanism includes a mounting slot on the mounting base, a fixed bracket is fixedly installed in the mounting slot, and a cooling fan is fixedly installed on the fixed bracket. By installing the cooling fan, the cooling fan in the mounting slot of the mounting base can dissipate heat from the circuit board when it is working, ensuring the working condition of the circuit board and extending the service life of the circuit board.

[0009] Preferably, both ends of the mounting base are fixedly provided with fasteners. The fasteners facilitate the installation of the mounting base into the device where the circuit board needs to be installed, thereby facilitating the installation of the circuit board.

[0010] Preferably, the mounting base overlaps with the circuit board and is adapted to the size of the circuit board. By docking the mounting base with the circuit board, the tightness of the connection between the mounting base and the circuit board is improved, thereby improving the stability of the circuit board after installation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1) This quick-release circuit board fastener allows the lever to disengage from the slot and retract from the locking hole by pulling the handle outward. Then, the fixing rod can be pulled out of the insertion hole to disconnect the circuit board from the mounting base, thus achieving quick disassembly of the circuit board. At the same time, when the circuit board is working, the heat dissipation fan in the mounting slot of the mounting base can dissipate heat from the circuit board, ensuring the working condition of the circuit board and extending its service life.

[0013] 2) This quick-release circuit board fastener works by pulling the handle outward, causing the connecting rod to move out of the slot and into the movable cavity via the sliding plate. At this time, the clamp is in a compressed state. Then, the fixing rod is inserted into the insertion hole through the fixing hole, and the locking hole on the fixing rod is aligned with the slot in the insertion hole. Finally, the handle is released, and the clamp automatically passes through the locking hole and engages with the slot under the spring's rebound, thus locking and fixing the circuit board and enabling the circuit board to be installed quickly.

[0019] 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.

[0020] Example 1

[0021] Combination Figures 1-4 A quick-release circuit board fastener includes a circuit board 1 and a mounting base 2. Both ends of the mounting base 2 are fixedly provided with fasteners 3. The mounting base 2 overlaps with the circuit board 1 and is adapted to the size of the circuit board 1. A disassembly and assembly mechanism 4 is provided between the circuit board 1 and the mounting base 2. A heat dissipation mechanism 5 is provided on the mounting base 2.

[0022] See Figure 2 and Figure 4 Furthermore, the disassembly and assembly mechanism 4 includes a fixing rod 403, on which a mounting block 405 is fixedly mounted. The circuit board 1 has a fixing hole 401 adapted to the fixing rod 403, and the mounting base 2 has an insertion hole 402 corresponding to the fixing hole 401. The fixing rod 403 passes through the fixing hole 401 and is inserted into the insertion hole 402. The fixing rod 403 has a locking hole 404, and the insertion hole 402 has a slot 406 corresponding to the locking hole 404. The mounting base 2 has a movable cavity 407, in which a sliding component is slidably connected. A plate 408 is provided with a locking rod 409 fixedly installed on one side of the sliding plate 408 and a connecting rod 410 fixedly installed on the other side of the sliding plate 408. A spring 411 is sleeved on the connecting rod 410 and the spring 411 is fixedly installed between the sliding plate 408 and the movable cavity 407. The locking rod 409 slides through the movable cavity 407 and passes through the locking hole 404 to engage with the locking groove 406. The end of the connecting rod 410 away from the sliding plate 408 slides through the movable cavity 407 and is fixedly connected to a connecting plate 412. A handle 413 is fixedly installed on one side of the connecting plate 412.

[0023] Specifically, by pulling the handle 413 outward, the connecting rod 410 moves the locking rod 409 out of the slot 406 and into the movable cavity 407 via the sliding plate 408. At this time, the locking rod 409 is in a compressed state. Then, the fixing rod 403 is inserted into the insertion hole 402 through the fixing hole 401, and the locking hole 404 on the fixing rod 403 is aligned with the slot 406 in the insertion hole 402. Finally, the handle 413 is released, and the locking rod 409 automatically passes through the locking hole 404 and engages with the slot 406 under the rebound action of the spring 411, thereby locking and fixing the circuit board 1, enabling the circuit board 1 to be installed quickly. By pulling the handle 413 outward, the locking rod 409 is disengaged from the slot 406 and the locking hole 404 and moves back. Then, the fixing rod 403 is pulled out of the insertion hole 402 through the mounting block 405, thereby disconnecting the circuit board 1 from the mounting base 2 and enabling the quick disassembly of the circuit board 1.

[0024] See Figure 3 Furthermore, the heat dissipation mechanism 5 includes a mounting groove 501 opened on the mounting base 2, a fixed bracket 502 fixedly installed in the mounting groove 501, and a cooling fan 503 fixedly installed on the fixed bracket 502.

[0025] Specifically, when the circuit board 1 is in operation, the cooling fan 503 in the mounting slot 501 of the mounting base 2 can dissipate heat from the circuit board 1, ensuring the working condition of the circuit board 1 and extending the service life of the circuit board 1.

[0026] In actual operation, the mounting base 2 is fixedly installed in the equipment by the fastener 3. When installing the circuit board 1, the circuit board 1 is placed on the mounting base 2, and the fixing hole 401 on the circuit board 1 is aligned with the insertion hole 402 on the mounting base 2. Then, the pull handle 413 is pulled outward, so that the connecting rod 410 drives the locking rod 409 to disengage from the slot 406 and move into the movable cavity 407 through the sliding plate 408. At this time, the locking rod 409 is in a compressed state. Then, the fixing rod 403 is inserted into the insertion hole 402 through the fixing hole 401, and the locking hole 404 on the fixing rod 403 is aligned with the slot 406 in the insertion hole 402. Finally, the pull handle 413 is released, and the locking rod 409 automatically passes through the locking hole 404 and engages with the slot 406 under the rebound action of the spring 411, thereby locking and fixing the circuit board 1 and completing the quick installation of the circuit board 1.

[0027] When disassembling circuit board 1, simply pull the handle 413 outward to make the lever 409 disengage from the slot 406 and the locking hole 404 and retract. Then, pull the fixing rod 403 out of the insertion hole 402 through the mounting block 405 to disconnect circuit board 1 from mounting base 2 and achieve quick disassembly of circuit board 1.

[0028] When the circuit board 1 is working, the heat dissipation fan 503 in the mounting slot 501 of the mounting base 2 can dissipate heat from the circuit board 1, ensuring the working condition of the circuit board 1 and extending the service life of the circuit board 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
