[0023] Specifically, the adjustable distance heat dissipation device 2 includes a vertical plate 21, a heat dissipation component 22, a screw rod 23, a movable platform 24 and a rotating block 25. Two vertical plates 21 are installed on the side of the mounting plate 1 close to the two assembly rod components 3, a rotating block 25 is arranged between the two vertical plates 21, and movable platforms 24 are arranged on both sides of the two vertical plates 21.

[0024] By adopting the above technical solution, the staff can adjust the distance between the two assembly rod assemblies 3 and other structures by cooperating with the screw rod 23 and the moving platform 24 when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the heat dissipation assembly 22 includes a ventilation net 221, a connection box 222 and a fan 224. The connection box 222 is installed on the side of the mobile platform 24 close to the assembly rod assembly 3, the fan 224 is installed on the inner side of the connection box 222, and the ventilation net 221 is installed on the top of the connection box 222.

[0026] By adopting the above technical solution, the circuit board can dissipate heat to the board body 8 to a certain extent through the cooperation of structures such as the ventilation net 221 and the fan 224 when needed, thereby reducing the possibility of overheating and damage to the board body 8.

[0027] Specifically, the heat dissipation assembly 22 further includes a filter 223 , and the filter 223 is installed on both sides of the two connection boxes 222 that are away from each other.

[0029] When the present embodiment is used, when it is necessary to use a multilayer printed circuit board, the mounting plate 1 is fixed in the working position by means of screws and mounting holes 5, and then the staff rotates the rotating block 25 between the two vertical plates 21 in the adjustable heat dissipation device 2, thereby driving the two screw rods 23 to rotate. The screw rods 23 are threadedly connected to the movable platform 24, and the movable platform 24 is close to the mounting plate 1, so the two screw rods 23 drive the two movable platforms 24 to move, thereby adjusting the distance between the two assembly rod assemblies 3 and other structures, and then the board body 8 is put on the two assembly rod assemblies 3, and then the two connection assemblies 6 are manipulated to make the two fastening caps 7 cooperate with the two assembly rod assemblies 3 to fix the position of the board body 8, and then the fans 224 in the two heat dissipation assemblies 22 are started. Under the action of the two fans 224, the outside air enters the two connection boxes 222 after being filtered by the two filter screens 223, and then blows from the two ventilation nets 221 to the board body 8, thereby dissipating the heat of the board body 8, and then it can be used.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the buffer lighting device 4 includes an elastic rubber tube 41, a small damper 42 and a transparent shell 44, the transparent shell 44 is installed on the side of the assembly rod assembly 3 and the connecting assembly 6 close to the connecting box 222, the elastic rubber tube 41 is installed between the transparent shell 44 and the connecting box 222, and the small damper 42 is installed between the transparent shell 44 and the connecting box 222 and at a position located on the inner side of the elastic rubber tube 41.

[0032] By adopting the above technical solution, the circuit board can buffer external vibration to a certain extent through the cooperation of the elastic rubber tube 41 and the small damper 42, thereby reducing the possibility of the board body 8 being adversely affected and ensuring normal operation.

[0033] Specifically, the buffer lighting device 4 further includes a lighting lamp 43 , and a plurality of lighting lamps 43 are installed inside the transparent shell 44 .

[0034] By adopting the above technical solution, the circuit board can be provided with a certain amount of auxiliary lighting by the lighting lamp 43 when needed, thereby better meeting the working needs in different situations and ensuring the normal progress of the work.

[0035] When this embodiment is used, during use, the staff can start the various lighting lamps 43 in the transparent shell 44 of the buffer lighting device 4 for auxiliary lighting, and the elastic rubber tube 41 can cooperate with the small damper 42 to buffer external vibration.

[0036] The structure and principle of the assembly rod assembly 3 composed of an assembly rod and a rubber ring, the connecting assembly 6 composed of a fixed rod, a cross bar, a fixed block, a spring and a movable ring, the fastening cap 7, and the plate body 8 and the structure thereon in the utility model have been disclosed in a multilayer printed circuit board disclosed in Chinese patent application No. 202223512975.1, and its working principle is to cover the mounting hole opened on the plate body on the surface of the assembly rod, and when the plate body contacts the surface of the mounting hole, the fastening cap is then pulled upward and the movable ring is driven to squeeze the spring, and the fastening cap is rotated so that the fastening cap is located directly above the assembly rod. At this time, the fastening cap is released, so that the spring pushes the movable ring to move downward, and the movable ring will push the fastening cap downward through the cross bar and get stuck on the surface of the assembly rod to fix the plate body.

[0037] The structure and principle of the small and medium-sized damper 42 of the utility model have been disclosed in a micro-box device for computer network security disclosed in Chinese Patent Application No. 202020567163.9. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and use process of the utility model are as follows: when a multi-layer printed circuit board is needed, the mounting plate 1 is fixed at the working position by screws and mounting holes 5, and then the staff rotates the rotating block 25 between the two vertical plates 21 in the adjustable heat dissipation device 2, thereby driving the two screw rods 23 to rotate, and the screw rods 23 are threadedly connected with the moving platform 24, and the moving platform 24 is close to the mounting plate 1, so the two screw rods 23 drive the two moving platforms 24 to move, thereby adjusting the distance between the two assembly rod components 3 and other structures, and then the plate body 8 is put on the two assembly rod components 3, and then the two connecting components 6 are manipulated. The two fastening caps 7 are made to cooperate with the two assembly rod assemblies 3 to fix the position of the plate body 8, and then the fans 224 in the two heat dissipation assemblies 22 are started. Under the action of the two fans 224, the outside air enters the two connection boxes 222 after being filtered by the two filter screens 223, and then blows onto the plate body 8 from the two ventilation nets 221, so as to dissipate the heat of the plate body 8, so that it can be used; during use, the staff can start the various lighting lamps 43 in the transparent shell 44 of the buffer lighting device 4 for auxiliary lighting, and the elastic rubber tube 41 can cooperate with the small damper 42 to buffer the external vibration.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
