[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Embodiment 1, the specific structure of the utility model is as follows:

[0030] Please refer to the attached Figure 1-2 , Figure 1 This is a schematic diagram of the structure of the first quick-release component pre-installed with a PCB board body of the utility model. Figure 2 This is a schematic diagram of the structure of the first quick-release component of the utility model clamping the PCB board body.

[0031] The utility model provides a PCB circuit board with a quick-release structure, comprising a PCB board body 1, and also comprising a quick-release part, wherein the quick-release part is an integrated structure, and comprises a hard area arranged at the bottom and an elastic area 4 connected to the hard area, a cavity 7 is formed between the hard area and the elastic area 4, and a C-shaped card slot 6 is provided at the connection between the hard area and the elastic area;

[0032] A through hole is provided at the center of the hard area, a threaded hole 5 is provided at the center of the elastic area, and the through hole and the threaded hole 5 are coaxial;

[0033] The elastic area is provided with a card cavity 3 for the PCB board body 1 to enter, the threaded hole 5 is provided at the center of the bottom surface of the card cavity 3, and both sides of the card cavity 3 are provided with upwardly protruding hooks 2 and an open structure is formed between the hooks 2 on both sides.

[0034] The PCB circuit board further comprises a screw 8 , the cap diameter of the screw 8 is larger than the diameter of the via hole, and the threaded section of the screw 8 can pass through the via hole and be connected with the threaded hole 5 .

[0035] A preferred technical solution of this embodiment: the hard area is a metal structural part or a hard plastic structural part.

[0036] A preferred technical solution of this embodiment: the elastic area is an elastic plastic structural part.

[0037] A preferred technical solution of this embodiment: both the hard area and the elastic area are strip-shaped structures.

[0038] A preferred technical solution of this embodiment: the notch of the C-shaped slot 6 faces the cavity 7 or the outside of the cavity 7.

[0039] A preferred technical solution of this embodiment: the hook openings of the hook portions 2 on both sides are both facing inwards or outwards.

[0040] A preferred technical solution of this embodiment: the bottom width of the card cavity 3 is equal to the width of the PCB board body 1.

[0041] A preferred technical solution of this embodiment: the bottom width of the card cavity 3 is greater than the width of the PCB board body 1 by 0.1 to 1 mm.

[0042] The quick release part of the utility model has two installation methods, one is that the quick release part and the PCB board body 1 form a whole, and the other is that the quick release part is fixed in the installation shell of the PCB circuit board by screws.

[0043] 1. If a quick-release part is used to form a whole with the PCB board body 1, a raised male buckle is provided in the installation housing for the C-shaped card slot 6 to buckle. The specific installation process is as follows:

[0044] First, take at least 2 quick-release parts, place the long strip of PCB board body 1 into the cavity 3 of the quick-release part, and then pass the screw 8 through the through hole and tighten it with the threaded hole 5. Since the lower area of ​​the quick-release part is a hard area and will not deform, the elastic area 4 will drive the hooks 2 on both sides to clamp the PCB board body 1 inward after being pulled. The C-shaped card slot 6 is the dividing line between the hard area and the elastic area 4, and the C-shaped card slot 6 will open at an angle. If the notch of the C-shaped card slot 6 is set in the cavity 7, the C-shaped card slot 6 will narrow an angle, and then the C-shaped card slot 6 will clamp the male buckle tighter. If the notch of the C-shaped card slot 6 is set outside the cavity 7, the male buckle needs to be larger in design so that the male buckle can cooperate with the C-shaped card slot 6.

[0045] When the PCB body 1 needs to be repaired, the hooks 2 on both sides can be opened or the quick release part can be directly pulled out from the male buckle. After the PCB body 1 is replaced, it can be buckled again, which is convenient to operate.

[0046] Second, if the quick-release parts are fixed to the mounting housing of the PCB circuit board by screws, it is necessary to pre-form a hole at the mounting housing, align the through hole with the pre-formed hole, and then pass the screw 8 through the pre-formed hole and the through hole, and then tighten it with the threaded hole 5, so that the elastic area 4 sinks at an angle, and the hooks 2 on both sides form a clamp. It is only necessary to buckle the PCB board body 1 into the clamp with force. This method does not require the use of the C-shaped buckle groove 6.

[0047] Embodiment 2:

[0048] like Figure 3-4 As shown, Figure 3 This is a schematic diagram of the structure of the second quick-release component pre-installed with the PCB board body of the utility model. Figure 4 This is a schematic diagram of the structure of the second quick-release component of the utility model clamping the PCB board body.

[0049] Figure 3 is Figure 1 On the basis of the first prefabricated groove 9 and the second prefabricated groove 10, because when installing the product, a cover shell is needed, and the second prefabricated groove 10 can be buckled with a corresponding cover shell, so that the function of the quick release part is increased.

[0050] The first prefabricated groove 9 can be buckled with the side parts.

[0051] Embodiment 3:

[0052] The quick release part of the utility model can also be directly locked on the side wall of the installation shell, such as installing two opposite quick release parts on two opposite side walls, that is, the threaded section of the screw passes through the C-shaped slot 6 to lock the quick release part on the side wall, and then the PCB board body 1 is buckled in the clamping opening formed by the hooks 2 on both sides.

[0053] In summary, the PCB circuit board of the utility model is equipped with a quick-release part, through which the PCB circuit board can be quickly replaced, which is convenient for maintenance and improves maintenance efficiency. The quick-release part of the utility model uses a screw to pull the elastic area so that the hooks on both sides of the elastic area are clamped together to clamp the PCB circuit board. When the PCB circuit board needs to be replaced, the PCB circuit board can be disassembled by manually prying open the hooks on both sides, which is extremely convenient to operate.

[0054] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
