Technical Field
[0001] This utility model relates to the field of PCB circuit board technology, and specifically to a PCB circuit board structure that is easy to assemble and disassemble. Background Technology
[0002] In modern electronic devices, PCBs play a crucial role as providers of electrical connections for electronic components. However, traditional PCB installation and removal processes present numerous inconveniences. For example, the common installation method often uses screws for fixing. While this method ensures the stability of the PCB installation, in practical use, the disassembly process is quite cumbersome when repair, replacement, or upgrades are needed.
[0003] Therefore, it is necessary to invent a PCB circuit board structure that is easy to assemble and disassemble to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a PCB circuit board structure that is easy to assemble and disassemble, so as to solve the problems in the above-mentioned technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB circuit board structure that is easy to assemble and disassemble, comprising a loading assembly and a circuit board body. The loading assembly consists of a loading frame and a limiting cover plate. The top and front of the loading frame are both open. The circuit board body is placed inside the loading frame. The limiting cover plate is located at the top opening of the loading frame. The circuit board body is sandwiched between the loading frame and the limiting cover plate. One end of the limiting cover plate is hinged to the loading frame. The other end of the limiting cover plate is fixedly connected to a sealing plate. The sealing plate is located at the front opening of the loading frame. A locking fastener is installed on each side of the loading frame near its front opening. A locking movable part is installed at each end of the sealing plate. The two locking movable parts are respectively engaged with the two locking fasteners.
[0006] By designing the loading frame and limiting cover, and using the combination of locking fasteners and locking movable parts, the PCB circuit board can be quickly installed and removed, greatly simplifying the installation and removal process and improving work efficiency.
[0007] Preferably, each of the four bottom corners of the loading frame is fixedly connected to a mounting foot plate, and each mounting foot plate has a mounting groove on its surface.
[0008] Each of the four corners at the bottom of the loading frame is fixedly connected to a mounting foot plate. Each mounting foot plate has a mounting groove on its surface, which facilitates the fixing of the loading components in the designated position with fasteners, providing a stable installation base and enhancing the overall structural stability.
[0009] Preferably, the limiting cover has a window slot in the middle, which facilitates the exposure of electronic components on the surface of the circuit board body.
[0010] The limiting cover has a window slot in the middle, which makes it easy to expose the electronic components on the surface of the circuit board body. This not only facilitates the electrical connection between the circuit board body and the electronic equipment, but also facilitates the heat dissipation of the electronic components on the surface of the circuit board body during operation.
[0011] Preferably, a first rubber washer is fixedly connected to the bottom edge of the loading frame, and a second rubber washer is fixedly connected to the bottom edge of the limiting cover plate. Both the first and second rubber washers are in interference contact with the edge of the circuit board body.
[0012] Both rubber gaskets No. 1 and No. 2 are in interference contact with the edge of the circuit board body, which plays a role in anti-slip and protection, preventing damage to the circuit board body during use and protecting the circuit board safety.
[0013] Preferably, a positioning hole is provided at each of the four corners of the edge of the circuit board body, and a positioning post is fixedly connected to each of the four corners of the bottom surface of the loading frame, and the four positioning posts are respectively inserted into the four positioning holes.
[0014] By interlocking the positioning stakes with the positioning holes, the circuit board body is initially positioned, which further enhances the stability of the circuit board body within the loading assembly and prevents the circuit board body from shaking or shifting.
[0015] Preferably, the positioning stake is installed through the first rubber gasket, and the top of the positioning stake is provided with a rounded chamfer, which can form a guide slope.
[0016] The rounded chamfer design makes it easier for the positioning posts to be smoothly inserted into the positioning holes when installing circuit boards, improving the convenience and accuracy of installation.
[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0018] 1. Through the design of the loading frame and limiting cover, as well as the cooperation of the locking fastener and the locking movable part, the rapid installation and disassembly of the PCB circuit board is realized. Compared with the traditional screw fixing method, this design greatly simplifies the installation and disassembly process and improves work efficiency.
[0019] 2. The positioning holes at the edge of the circuit board body are connected to the positioning posts on the bottom surface of the loading frame, which realizes the initial positioning of the circuit board and further enhances the stability of the circuit board in the loading assembly.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0029] This utility model provides, for example Figure 1-6 The diagram shows a PCB circuit board structure that is easy to assemble and disassemble, including a loading assembly and a circuit board body 1. The loading assembly consists of a loading frame 2 and a limiting cover 3. The top and front of the loading frame 2 are open. The circuit board body 1 is placed inside the loading frame 2. The limiting cover 3 is set at the top opening of the loading frame 2. The circuit board body 1 is sandwiched between the loading frame 2 and the limiting cover 3. One end of the limiting cover 3 is hinged to the loading frame 2, and the other end of the limiting cover 3 is fixedly connected to a sealing plate 4. The sealing plate 4 is located at the front opening of the loading frame 2. A latching fastener 5 is installed on each side of the loading frame 2 near its front opening. A latching movable part 6 is installed at each end of the sealing plate 4. The two latching movable parts 6 are respectively engaged with the two latching fasteners 5.
[0030] In one aspect of this embodiment, a mounting foot plate 7 is fixedly connected to each of the four corners of the bottom of the loading frame 2. Each mounting foot plate 7 has a mounting groove on its surface. A window groove 8 is provided in the middle of the limiting cover plate 3. The window groove 8 facilitates the exposure of electronic components on the surface of the circuit board body 1. A first rubber gasket 9 is fixedly connected to the inner bottom edge of the loading frame 2. A second rubber gasket 10 is fixedly connected to the bottom edge of the limiting cover plate 3. Both the first rubber gasket 9 and the second rubber gasket 10 are in interference contact with the edge of the circuit board body 1. A positioning hole 11 is provided at each of the four corners of the edge of the circuit board body 1. A positioning post 12 is fixedly connected to each of the four corners of the inner bottom surface of the loading frame 2. The four positioning posts 12 are respectively inserted into the four positioning holes 11. The positioning posts 12 are set through the first rubber gasket 9. A round chamfer is provided at the top of the positioning post 12. The round chamfer can form a guide slope.
[0031] The circuit board body 1, the latching fastener 5, and the latching movable part 6 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.
[0032] Since the positioning hole 11 is located at the corner of the edge of the circuit board body 1, it does not damage the electronic components on the surface of the circuit board body 1, and therefore will not affect the normal function of the circuit board body 1.
[0033] Working principle of this utility model:
[0034] Refer to the instruction manual appendix Figure 1-6 When using this utility model, firstly, the loading component is fixedly installed at the designated position using fasteners through the mounting feet 7 fixedly connected to the four corners of the bottom of the loading frame 2 and the mounting grooves opened on the surface of the mounting feet 7;
[0035] Next, open the limiting cover 3. Since one end of the limiting cover 3 is hinged to the loading frame 2, it can be easily opened to expose the opening at the top of the loading frame 2.
[0036] Then, place the circuit board body 1 inside the loading frame 2. During the placement process, pay attention to the positioning holes 11 opened at the four corners of the edge of the circuit board body 1. These holes should correspond to the positioning pins 12 fixedly connected at the four corners of the bottom surface of the loading frame 2. Ensure that the four positioning pins 12 are inserted into the four positioning holes 11 respectively to achieve the initial positioning of the circuit board body 1.
[0037] Subsequently, the limiting cover plate 3 is closed, and the latching movable parts 6 installed at both ends of the sealing plate 4 are fastened to the latching fixing parts 5 installed on both sides of the loading frame 2 near its front opening. With the cooperation of the first rubber washer 9 and the second rubber washer 10, the circuit board body 1 is firmly clamped between the loading frame 2 and the limiting cover plate 3, thus realizing the assembly of the circuit board body 1.
[0038] When it is necessary to disassemble the circuit board body 1, simply unlock the latching movable part 6 and the latching fixed part 5, and then open the limiting cover 3 to easily remove the circuit board body 1 from the loading frame 2, which facilitates subsequent maintenance, replacement or upgrade operations.
