[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: a circuit board with an anti-static structure, comprising a circuit board body 1, on which a high temperature resistant board 2 is arranged. By arranging the high temperature resistant board 2, when the circuit board body 1 is used, the high temperature resistant board 2 increases the high temperature resistance of the circuit board body 1, thereby improving the heat resistance efficiency of the circuit board body 1;

[0019] An antistatic component 3 is provided on the high temperature resistant plate 2, and the antistatic component 3 includes a lower plate 31, the lower plate 31 is provided on the high temperature resistant plate 2, a fixing plate 32 is provided on the lower plate 31, a plurality of aluminum foil tubes 33 are provided in the fixing plate 32, and an upper plate 34 is provided on the fixing plate 32. By providing the fixing plate 32 and the aluminum foil tube 33, the fixing plate 32 supports and limits the aluminum foil tube 33, thereby ensuring that the aluminum foil tube 33 does not shake randomly in the fixing plate 32;

[0020] A voltage-resistant component 5 is provided on the anti-static component 3. The voltage-resistant component 5 includes a voltage-resistant plate 51. The voltage-resistant plate 51 is provided on the upper plate 34. A plurality of placement grooves 52 are provided on the voltage-resistant plate 51. Reinforcement strips 53 are provided in the placement grooves 52. By providing the voltage-resistant plate 51 and the reinforcement strips 53, with the cooperation of the voltage-resistant plate 51 and the reinforcement strips 53, the support stability of the circuit board body 1 during use is increased, the voltage-resistant area of ​​the circuit board body 1 is increased, the circuit board body 1 is prevented from breaking, and the load-bearing capacity of the circuit board body 1 is increased. The voltage-resistant plate 51 is connected to the electromagnetic shielding layer plate 4. An electromagnetic shielding layer plate 4 is provided on the voltage-resistant component 5. By providing the electromagnetic shielding layer plate 4, the electromagnetic shielding layer plate 4 can ensure that the stability of the circuit board body 1 is not disturbed.

[0021] Two guide sleeves 6 are provided on both sides of the circuit board body 1, and a guide rod 7 is slidably connected in the guide sleeve 6. By setting the guide rod 7 and the guide sleeve 6, the guide sleeve 6 supports and limits the guide rod 7, so that the guide rod 7 can slide up and down smoothly in the guide sleeve 6. A limit block 8 is provided at the top end of the guide rod 7, and a connecting block 10 is provided at the bottom end of the guide rod 7. A spring 9 is provided on the connecting block 10.

The other end of the spring 9 is connected to the guide sleeve 6.

[0022] The working principle of the utility model is:

[0023] When the circuit board body 1 is in use, the high temperature resistant board 2 on the circuit board body 1 increases the high temperature resistance of the circuit board body 1. The aluminum foil tube 33 has an anti-static function. The aluminum foil tube 33 arranged in a large area greatly increases the anti-static area, which not only improves the anti-static comprehensiveness of the circuit board body 1, but also increases the support stability of the circuit board body 1 during use and improves the pressure resistance area of ​​the circuit board body 1.

[0024] The electromagnetic shielding layer 4 can ensure that the stability of the circuit board is not disturbed. Through the cooperation of the guide sleeve 6, the guide rod 7, the spring 9 and the limit block 8, it can not only guide the circuit board body 1, but also provide buffering protection for the circuit board body 1 against impact force.
