It is also easy to introduce external dust into the housing and cause unfavorable effects on the circuit board. Moreover, the installation structure designed inside the existing circuit board housing generally requires screws to complete the fixing of the circuit board, which will cause the problem of inconvenience in disassembly and assembly between the circuit board and the housing.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1, reference Figure 1-5 A circuit board housing includes a housing 1, a circuit board body 3 is installed in the housing 1 through an installation mechanism, and the installation mechanism includes:

[0027] A slide groove 5 and a bidirectional screw 6. The slide groove 5 is provided on the bottom inner wall of the housing 1. The bidirectional screw 6 is rotatably installed in the slide groove 5. An anti-slip knob 9 is fixedly connected to the outer wall of one end of the bidirectional screw 6.

[0028] Two centering blocks 7 and two positioning clamping rods 8. The two centering blocks 7 are symmetrically screwed to two opposite threaded ends of the bidirectional screw 6. The outer walls of the two centering blocks 7 are slidably connected to the inner wall of the slide groove 5. The two positioning clamping rods 8 are symmetrically fixed to the top outer walls of the two centering blocks 7.

[0029] Furthermore, four No. 1 positioning posts 10 are fixed to the bottom inner wall of the housing 1, and No. 1 positioning holes are provided at the four corners of the circuit board body 3, and the four No. 1 positioning holes are respectively matched with the four No. 1 positioning posts 10;

[0030] In the specific implementation of this embodiment: during installation: the circuit board body 3 is placed in the housing 1 facing the four No. 1 positioning columns 10 to complete the preliminary positioning, and then the anti-slip knob 9 drives the bidirectional screw 6 to rotate forward, and then under the limit of the slide 5, the two centering blocks 7 threadedly connected to the bidirectional screw 6 will drive the two positioning clamping rods 8 to center and close together to clamp the circuit board body 3, so that the installation of the circuit board body 3 can be achieved;

[0031] When disassembling, the anti-slip knob 9 is used to drive the bidirectional screw 6 to rotate in the opposite direction, and then under the limit of the slide slot 5, the two centering blocks 7 threadedly connected to the bidirectional screw 6 will drive the two positioning clamping rods 8 to move away from each other, and the circuit board body 3 can be removed at this time;

[0032] In summary, the entire installation and removal process of the circuit board body 3 with the housing 1 does not require any tools, and the operation is simple and convenient, thereby improving the efficiency of installation and removal.

[0033] Example 2, reference Figure 1-6 , this embodiment is optimized on the basis of embodiment 1, specifically: a circuit board housing, further comprising an inspection cover 2 adapted to the housing 1, the inspection cover 2 being connected to the outside of the housing 1 through four buckle assemblies 11;

[0034] Furthermore, the four buckle assemblies 11 are distributed in a rectangular array, and the buckle assemblies 11 include an elastic band 12 fixedly connected to the outer wall of the inspection cover 2, a buckle male end 13 fixedly connected to the elastic band 12, and a buckle female end 14 fixedly connected to the outer wall of one side of the housing 1 and adapted to the buckle male end 13;

[0035] Furthermore, the outer walls at the four corners of the top of the housing 1 are all fixed with No. 2 positioning columns 15, and the four corners of the inspection cover 2 are all provided with No. 2 positioning holes, and the four No. 2 positioning holes are respectively matched with the four No. 2 positioning columns 15;

[0036] When installing the inspection cover 2: place the inspection cover 2 on the top of the housing 1 along the four No. 2 positioning columns 15, then pull the elastic band 12 and insert the male buckle end 13 into the corresponding female buckle end 14, and insert the four male buckle ends 13 into the corresponding four female buckle ends 14 in turn according to this operation method to complete the fixed installation of the inspection cover 2;

[0037] When disassembling the inspection cover 2, the four male buckle ends 13 are sequentially unfastened from the corresponding four female buckle ends 14, and then the inspection cover 2 can be taken out from the four No. 2 positioning columns 15 to complete the disassembly. In this way, the entire installation and disassembly process does not require any tools, and the operation is simple and convenient, which improves the efficiency of assembly and disassembly.

[0038] Furthermore, a cooling fan 4 is fixedly installed on one side outer wall of the housing 1, a ventilation port adapted to the position of the cooling fan 4 is opened on one side of the housing 1, a first dust filter 16 is fixedly connected in the ventilation port, a mounting port is opened at the bottom of the inspection cover 2, a second dust filter 18 is fixedly connected in the mounting port, and a heat dissipation port 17 which is equidistantly distributed and communicates with the mounting port is opened on the top of the inspection cover 2;

In the process of heat dissipation, the dust-proof effect of the No. 1 dust filter 16 and the No. 2 dust filter 18 can effectively prevent external dust from being brought into the shell 1 and causing adverse effects on the circuit board body 3.
