Description

Technical Field

[0001] The utility model relates to the field of circuit board installation structures, in particular to a quick-install circuit board with a built-in fixing component. Background Art

[0002] Quick-install circuit boards are usually equipped with special connection structures or fixing devices, which eliminate the need for complex tools and tedious operating steps during the installation process. They can be quickly fixed to the corresponding position of the equipment, greatly saving installation time.

[0003] Some existing quick-detachable circuit boards are directly and quickly connected to the device installation location. There are also quick-detachable circuit boards with built-in fixing components, which can be quickly connected to the device installation location using the fixing components. However, once maintenance work occurs, the circuit board and the fixing components need to be separated. The existing quick-detachable circuit boards with built-in fixing components are mostly connected to the fixing components with bolts to ensure the stability of the combination during carrying and use, but it is also troublesome to separate them when maintenance is required.

[0004] To this end, a quick-install circuit board with built-in fixing components is proposed. Utility Model Content

[0005] In view of the above problems, the present invention provides a quick-install circuit board with a built-in fixing assembly to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] A quick-install circuit board with a built-in fixing assembly includes a circuit board and a fixing assembly, the fixing assembly includes a mounting seat and a pressure plate, the circuit board is located between the mounting seat and the pressure plate, both ends of the mounting seat are connected to anti-slip columns through an elastic mechanism, the outer surfaces of the anti-slip columns are fixedly connected to symmetrical anti-slip bolts, both ends of the pressure plate are fixedly connected to protrusions, the bottom ends of the protrusions are fixedly connected to symmetrical supporting feet, the surfaces of the supporting feet are provided with bayonet slots, the diameter of the bayonet slots is adapted to the diameter of the anti-slip bolts.

[0008] The working principle of the above technical solution is as follows:

[0009] When in use, directly place the circuit board on the surface of the mounting base, and then place the pressure plate on the top surface of the circuit board. The bottom end of the support foot will fit against the top surface of the anti-slip bolt. Then press the two anti-slip columns to make the anti-slip columns move horizontally. During this process, the support foot will change from a state where the bottom end fits against the anti-slip bolt to a state where the bayonet and the anti-slip bolt are opposite. Then release the anti-slip column and let it rebound with the anti-slip bolt stuck on the inner wall of the bayonet to limit the circuit board. When you need to open the fixing assembly to install the circuit board separately, push the anti-slip column again to release the anti-slip bolt, let the pressure plate be lifted from the top surface of the mounting base, and take out the circuit board.

[0010] In a further technical solution, the bottom surface of the pressing plate and the top surface of the mounting seat are both magnetic surfaces.

[0011] Through the above technical solution, the pressing plate can be automatically aligned with the top surface of the mounting seat, so that the circuit board can be fixed in place on the surface of the fixed component conveniently and quickly.

[0012] In a further technical solution, a slot is provided on the top surface of the pressing plate, a pressing sheet is fixedly connected to the inner wall of the top opening of the slot, and the bottom surface of the pressing sheet is tightly fitted to the top surface of the circuit board.

[0013] Through the above technical solution, during installation, the circuit board is placed on the top surface of the mounting seat, and then the bottom surface of the pressing sheet can press down the circuit board through the magnetic effect. After limiting the position, the circuit board is prevented from shaking on the inner wall of the empty slot. At the same time, the opening of the empty slot can facilitate the exposure of the circuit board for connecting the circuits.

[0014] In a further technical solution, the distance between two adjacent supporting legs is consistent with the diameter of the anti-slip column.

[0015] Through the above technical solution, it is convenient to fit the pressure plate and the mounting seat, and then initially clamp the support legs on the outer wall of the anti-slip column to provide stability for installation and use.

[0016] In a further technical solution, a slot is provided on the top surface of the mounting seat, and the magnetic surface of the top surface of the mounting seat is located outside the opening of the slot.

[0017] The above technical solution facilitates placing the circuit board on the top surface of the mounting seat, has a preliminary limiting effect, and provides multi-layer stability when used in conjunction with the pressure plate.

[0018] In a further technical solution, the elastic mechanism includes a spring, adjustment grooves are provided at both ends of the mounting seat, the end of the anti-slip column away from the anti-slip bolt is inserted into the inner wall of the adjustment groove, and the two ends of the spring are respectively fixed on the opposite surfaces of the anti-slip column and the adjustment groove.

[0019] Through the above technical solution, when the circuit board is installed on the top surface of the mounting base, pressing the two opposite anti-slip columns can compress the spring. When the anti-slip columns are released, the restoring effect of the spring can be utilized to engage the anti-slip bolt with the bayonet.

[0020] In a further technical solution, a pressure block is fixedly connected to one end of the anti-slip column away from the adjustment groove, and the diameter of the pressure block is larger than the diameters of the anti-slip column and the adjustment groove.

[0021] Through the above technical solution, the anti-slip column is prevented from being fully inserted into the inner wall of the adjustment groove, providing auxiliary protection effect. Once the rebound force is insufficient, the anti-slip bolt can be stuck on the inner wall of the bayonet by pulling the pressure block.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The anti-slip column, anti-slip bolt and the bracket's snap-on action, as well as the elastic action of the spring, ensure the stability of the circuit board during use. At the same time, the pressure piece and the card slot further enhance the fixing effect of the circuit board, preventing the circuit board from shaking between the mounting base and the pressure plate. In addition, by pushing the anti-slip column and releasing the limit of the anti-slip bolt, the pressure plate can be easily opened to take out the circuit board. The detachable structure improves the adaptability of the installation scene and also facilitates the maintenance of the equipment and replacement of the circuit board.

[0034] Example:

[0035] See also Figure 1-5 A quick-install circuit board with a built-in fixing component includes a circuit board 1 and a fixing component 2. The fixing component 2 includes a mounting base 21 and a pressure plate 22. The circuit board 1 is located between the mounting base 21 and the pressure plate 22. Both ends of the mounting base 21 are connected to anti-slip columns 28 through an elastic mechanism. The outer surface of the anti-slip column 28 is fixedly connected to a symmetrical anti-slip bolt 29. Both ends of the pressure plate 22 are fixedly connected to a protrusion 23. The bottom end of the protrusion 23 is fixedly connected to a symmetrical support foot 24. The surface of the support foot 24 is provided with a bayonet 25. The diameter of the bayonet 25 is adapted to the diameter of the anti-slip bolt 29.

[0036] The working principle of the above technical solution is as follows:

[0037] When in use, directly place the circuit board 1 on the surface of the mounting seat 21, and then place the pressing plate 22 on the top surface of the circuit board 1. The bottom end of the support leg 24 will fit on the top surface of the anti-slip bolt 29, and then press the two anti-slip columns 28 to make the anti-slip column 28 move horizontally. During this process, the support leg 24 will change from the state of the bottom end fitting the anti-slip bolt 29 to the state where the bayonet 25 is opposite to the anti-slip bolt 29. Then release the anti-slip column 28 and let the anti-slip column 28 rebound with the anti-slip bolt 29 to be stuck on the inner wall of the bayonet 25 to limit the circuit board 1. When it is necessary to open the fixing component 2 to allow the circuit board 1 to be installed separately, push the anti-slip column 28 again to release the anti-slip bolt 29, so that the pressing plate 22 is lifted from the top surface of the mounting seat 21, and the circuit board 1 can be taken out.

[0038] The bottom surface of the pressing plate 22 and the top surface of the mounting base 21 are both magnetic surfaces.

[0039] The pressing plate 22 can be automatically aligned with the top surface of the mounting seat 21 , so that the circuit board 1 can be fixed on the surface of the fixing component 2 conveniently and quickly.

[0040] See also Figure 3 and Figure 4 The top surface of the pressing plate 22 is provided with an empty slot 221 , and the inner wall of the top opening of the empty slot 221 is fixedly connected with a pressing piece 222 , and the bottom surface of the pressing piece 222 is tightly fitted with the top surface of the circuit board 1 .

[0041] During installation, the circuit board 1 is placed on the top surface of the mounting base 21, and then the bottom surface of the pressing piece 222 can press down the circuit board 1 through the magnetic effect. After limiting, the circuit board 1 is prevented from shaking on the inner wall of the slot 221. At the same time, the opening of the slot 221 can conveniently expose the circuit board 1 for connecting the circuits.

[0042] See also Figure 1 and Figure 3 The distance between two adjacent supporting legs 24 is consistent with the diameter of the anti-skid column 28.

[0043] After the pressing plate 22 is fitted onto the mounting base 21 , the legs 24 are initially clamped onto the outer wall of the anti-slip column 28 to provide stability for installation and use.

[0044] See also Figure 2 and Figure 4 A card slot 3 is provided on the top surface of the mounting seat 21 , and the magnetic surface of the top surface of the mounting seat 21 is located outside the opening of the card slot 3 .

[0045] It is convenient to place the circuit board 1 on the top surface of the mounting seat 21, which has a preliminary limiting effect and provides multi-layer stability when used in conjunction with the pressing plate 22.

[0046] See also Figure 1 and Figure 3The elastic mechanism includes a spring 27, and adjustment grooves 26 are opened at both ends of the mounting seat 21. The end of the anti-slip column 28 away from the anti-slip bolt 29 is inserted into the inner wall of the adjustment groove 26, and the two ends of the spring 27 are respectively fixed on the opposite surfaces of the anti-slip column 28 and the adjustment groove 26.

[0047] When the circuit board 1 is mounted on the top surface of the mounting base 21 , the two opposite anti-slip posts 28 are pressed to compress the spring 27 . When the anti-slip posts 28 are released, the restoring effect of the spring 27 can be utilized to engage the anti-slip latch 29 with the bayonet 25 .

[0048] See also Figure 3 and Figure 4 One end of the anti-skid column 28 away from the adjustment groove 26 is fixedly connected to a pressing block 281 , and the diameter of the pressing block 281 is larger than the diameters of the anti-skid column 28 and the adjustment groove 26 .

[0049] To prevent the anti-skid column 28 from being completely inserted into the inner wall of the adjustment groove 26 , an auxiliary protection effect is provided. Once the rebound force is insufficient, the anti-skid latch 29 can be clamped on the inner wall of the bayonet 25 by pulling the pressure block 281 .

[0050] During operation, the circuit board 1 is placed on the surface of the mounting seat 21. At this time, the circuit board 1 is initially limited by the slot 3 opened on the top surface of the mounting seat 21, and then the pressure plate 22 is placed on the top surface of the circuit board 1. At this time, the bottom end of the support leg 24 will be in contact with the top surface of the anti-slip latch 29. Since the bottom surface of the pressure plate 22 and the top surface of the mounting seat 21 are both magnetic surfaces, the pressure plate 22 will automatically align with the top surface of the mounting seat 21, which is convenient for quickly fixing the circuit board 1 on the surface of the fixed component 2. Then press the two anti-slip columns 28 to make the anti-slip columns 28 move horizontally. During this process, the support leg 24 will change from a state in which the bottom end is in contact with the anti-slip latch 29 to a state in which the bayonet 25 is opposite to the anti-slip latch 29. At this time, the end of the anti-slip column 28 away from the anti-slip latch 29 is inserted into the inner wall of the adjustment slot 26, compressing the spring 27, and then releasing the anti-slip column 28 to allow the anti-slip column 28 to be adjusted on the spring 27. If the anti-skid column 28 has insufficient rebound force, the anti-skid latch 29 can be stuck on the inner wall of the bayonet 25 by pulling the pressure block 281.

[0051] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
