Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a safety protection circuit board. Background Technology

[0002] A circuit board, also known as a printed circuit board, is a core component that provides mechanical assembly support and electrical connections for components in various electronic systems, while also carrying out signal transmission, signal reception and power supply for electronic devices.

[0003] However, in the existing technology, if there is a lack of fixing or buffering devices during the transfer of circuit boards, the circuit boards may collide, vibrate or fall due to external forces, resulting in physical damage. This damage may include board cracks, loose or detached electronic components, or even short circuits or open circuits, affecting the normal function of the product. In addition, transferring circuit boards without stable support for a long time may also accelerate the fatigue damage of solder joints due to frequent mechanical impacts and vibrations, reducing the reliability of the product. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the lack of fixing or buffering devices causes circuit boards to collide, vibrate, or fall due to external forces, resulting in physical damage. Therefore, a safety protection circuit board is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety protection circuit board, including a circuit board body, mounting brackets slidably inserted on both sides of the circuit board body, a protective mechanism installed on the top of the two mounting brackets, and a second protective cover fixedly connected to the top of one of the mounting brackets, and a second dustproof net fixedly connected to the inner side of the second protective cover.

[0006] The protective mechanism includes a slide rail and a first protective cover. The bottom of both ends of the first protective cover is provided with a slide groove, which is slidably connected to the slide rail. The top of both sides of the first protective cover is provided with a plug-in groove, and a limit plate is inserted into the plug-in groove. Locking components are installed on the bottom of both sides of the first protective cover. Multiple plug-in holes are provided on the surface of the slide rail, and a first dustproof net is fixedly connected to the top of the slide rail.

[0007] Preferably, the locking component includes a fixing block, which is fixedly connected to the side wall of the first protective cover.

[0008] Preferably, a limit block is slidably connected to the inner side of the fixed block, and a plug rod is fixedly connected to the inner side of the limit block.

[0009] Preferably, one end of the plug rod is plugged into the plug hole.

[0010] Preferably, one end of the limiting block is fixedly connected to a pull rod, and one end of the pull rod is slidably connected to the fixed block.

[0011] Preferably, a spring is fitted onto the outer surface of the pull rod, with one end of the spring abutting against the limiting block.

[0012] Preferably, the top of the mounting bracket is threaded with a threaded rod, and the bottom end of the threaded rod is threadedly connected to the main body of the circuit board.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first protective cover is slidably connected to the slide rail via a slide groove and is precisely positioned by a locking component to ensure stability and prevent loosening or displacement. The limiting plate is fixed by a plug-in slot, and its top width is greater than the width of the plug-in slot to effectively prevent slippage and further enhance the fixing effect. The second protective cover and double-layer dustproof net installed subsequently can effectively cover the circuit board to prevent damage to electronic components from dust, impurities and external impacts, while reducing the impact of vibration, improving the stability and durability of the equipment, and improving the overall safety, reliability and service life of the circuit board.

[0015] 2. In this utility model, the spring elastically pushes the limiting block, causing the plug rod to pass through the through hole of the first protective cover and be inserted into the plug hole in sequence, achieving precise docking and stable locking. The spring rebound force ensures that the plug rod is stably inserted, preventing loosening or falling off, thereby improving the safety and reliability of the connection. During disassembly, pulling the pull rod can drive the limiting block and the plug rod to move backward synchronously, allowing the plug rod to smoothly exit the plug hole and complete the separation under the spring reset action, making the protective cover easy to remove, simplifying the installation and disassembly process, improving maintenance and replacement efficiency, while ensuring that the protective cover is firmly fixed, improving the safety and durability of the overall structure.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a safety protection circuit board, including a circuit board body 1, with mounting brackets 2 slidably inserted on both sides of the circuit board body 1, a protective mechanism 3 installed on the top of the two mounting brackets 2, and a second protective cover 4 fixedly connected to the top of one of the mounting brackets 2, and a second dustproof net 41 fixedly connected to the inner side of the second protective cover 4.

[0024] The protective mechanism 3 includes a slide rail 31 and a first protective cover 32. The bottom of both ends of the first protective cover 32 are provided with slide grooves 37, which are slidably connected to the slide rail 31. The top of both sides of the first protective cover 32 are provided with insertion slots 36, and limit plates 35 are inserted into the insertion slots 36. Locking components 33 are installed on the bottom of both sides of the first protective cover 32. The surface of the slide rail 31 is provided with multiple insertion holes 38, and a first dustproof net 34 is fixedly connected to the top of the slide rail 31.

[0025] The specific settings and functions of this embodiment will be described in detail below. During installation, it is first necessary to ensure that the mounting bracket 2 and the circuit board body 1 can be smoothly slidably inserted to achieve a stable connection. After insertion, the protective mechanism 3 can be further installed to enhance the protective performance of the circuit board body 1. During installation, the bottom of the first protective cover 32 is slidably connected to the slide rail 31 through the slide groove 37, so that it can smoothly complete the initial installation and ensure the stability of the protective cover, preventing loosening or displacement.

[0026] Subsequently, the locking component 33, in conjunction with the insertion hole 38, achieves precise positioning of the first protective cover 32, further enhancing installation reliability. After insertion into the insertion hole 38, the locking component 33 effectively prevents accidental displacement of the protective cover during subsequent operations, improving the overall structural stability. Based on this, a limiting plate 35 can be installed, secured via an insertion slot 36. Simultaneously, the width of the top of the limiting plate 35 is greater than the width of the insertion slot 36, ensuring that the limiting plate 35 will not slip after insertion, thereby further strengthening the fixation of the first protective cover 32 and improving the overall structural safety and durability.

[0027] After the first protective cover 32 and the limiting plate 35 are installed, a second protective cover 4 and a second dustproof net 41 can be further installed to provide more comprehensive protection. These components can effectively cover the electronic components on the surface of the circuit board body 1, preventing damage to the electronic components from external dust, impurities, and accidental collisions. In addition, the dual protection design of the first dustproof net 34 and the second dustproof net 41 not only reduces the possibility of external contaminants entering the circuit board, but also acts as a buffer during circuit board transfer, reducing the risk of vibration and impact, thereby effectively improving the service life and reliability of the circuit board.

[0028] Example 2: Figure 3 and Figure 4 As shown, the locking assembly 33 includes a fixing block 331, which is fixedly connected to the side wall of the first protective cover 32. A limit block 334 is slidably connected to the inner side of the fixing block 331, and a plug rod 333 is fixedly connected to the inner side of the limit block 334. One end of the plug rod 333 is inserted into the plug hole 38. A pull rod 332 is fixedly connected to one end of the limit block 334, and one end of the pull rod 332 is slidably connected to the fixing block 331. A spring 335 is sleeved on the outer surface of the pull rod 332, and one end of the spring 335 abuts against the limit block 334. A threaded rod 21 is threadedly connected to the top of the mounting bracket 2, and the bottom end of the threaded rod 21 is threadedly connected to the circuit board body 1.

[0029] The overall effect of this embodiment is that, during locking, the elastic force of the spring 335 pushes the limiting block 334 to slide along the interior of the fixing block 331, causing the limiting block 334 to move the plug rod 333 and the pull rod 332 synchronously. As the plug rod 333 advances, it passes through the preset through holes of the first protective cover 32 in sequence and finally inserts into the corresponding plug hole 38, achieving precise docking and stable locking of the first protective cover 32. During this process, the rebound force of the spring 335 ensures that the plug rod 333 can maintain a stable insertion state, preventing loosening or falling off, thereby enhancing the safety and reliability of the connection.

[0030] During disassembly, the operator can manually pull the lever 332. The backward movement of the lever 332 will drive the limiting block 334 and the insertion rod 333 to move backward together, allowing the insertion rod 333 to gradually exit the insertion hole 38. During this process, the spring 335 is compressed and stores a certain amount of elastic potential energy, ensuring that the insertion rod 333 can smoothly disengage. Once the insertion rod 333 has completely disengaged from the insertion hole 38, the first protective cover 32 can be easily removed from the fixing block 331. This design not only simplifies the installation and disassembly process of the protective cover, but also improves the convenience of maintenance and replacement while ensuring structural stability.

[0031] The usage and working principle of this device are as follows: During installation, first slide the mounting bracket 2 into the circuit board body 1, and then install the protective mechanism 3. During installation, first slide the groove 37 at the bottom of the first protective cover 32 into the slide rail 31 to complete the initial installation. Next, use the locking component 33 in conjunction with the insertion hole 38 to further position and lock the first protective cover 32. During locking, the spring force of the spring 335 pushes the limiting block 334 to slide inside the fixing block 331, thereby causing the insertion rod 333 and the pull rod 332 to move together, allowing the insertion rod 333 to pass through the first protective cover 32 and insert into the insertion hole 38, thus fixing the first protective cover 32.

[0032] During disassembly, pulling the lever 332 causes the limiting block 334 and the insertion rod 333 to move together, thereby disengaging the insertion rod 333 from the insertion hole 38 and simultaneously compressing the spring 335, thus unlocking and disassembling the first protective cover 32. Subsequently, the limiting plate 35 is inserted into the insertion slot 36 to complete the installation of the limiting plate 35. Because the top width of the limiting plate 35 is greater than the width of the insertion slot 36, it serves a limiting function.

[0033] Finally, a second protective cover 4 and a second dustproof net 41 are installed to further protect the electronic components on the circuit board body 1. Meanwhile, the first dustproof net 34 and the second dustproof net 41 effectively protect the electronic components from damage during transfer.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
