The connecting body includes a circular upper clamping plate and a circular lower clamping plate. An alloy conductive layer is covered on the opposite surface of the upper clamping plate and the lower clamping plate. The locking mechanism includes an anti-loosening bolt and nuts at both ends of the anti-loosening bolt. Corresponding through holes are provided on the upper clamping plate and the lower clamping plate. The anti-loosening bolt passes through the through hole and the nuts are tightened to lock the flat steel located between the upper clamping plate and the lower clamping plate.

[0006] In a preferred embodiment, through holes are located at the center of the upper and lower clamping plates and at the edges of the plates in a uniformly distributed radial direction.
[0007] In a preferred embodiment, an elastic washer is provided between the upper clamping plate and / or the lower clamping plate and between the nut.

[0018] Example 1
[0019] Please see Figure 1-4 As shown, this application provides a technical solution: a weld-free grounding flat steel connection device, including a connection body and a locking mechanism; the connection body is used to clamp the flat steel, and the locking mechanism is used to fix the clamping position of the connection body. The connection body includes a circular upper clamping plate 11 and a circular lower clamping plate 12. An alloy conductive layer is coated on the opposite surface of the upper clamping plate 11 and the lower clamping plate 12. The locking mechanism includes an anti-loosening bolt 21 and nuts 22 at both ends of the anti-loosening bolt 21. Corresponding through holes are provided on the upper clamping plate 11 and the lower clamping plate 12. The anti-loosening bolt 21 passes through the through hole and tightens the nut 22 to lock the flat steel between the upper clamping plate 11 and the lower clamping plate 12.
[0020] The alloy conductive layer is a conductive layer made of alloy material. The first serration 13 is set to increase the friction between the upper clamping plate 11 and the lower clamping plate 12 and the flat steel. The purpose of setting the circular upper clamping plate 11 and the circular lower clamping plate 12 is to facilitate the insertion of the flat steel between the upper clamping plate 11 and the lower clamping plate 12 from all directions. There is no strict requirement on the insertion angle of the flat steel.
[0021] When the flat steel is inserted between the upper clamping plate 11 and the lower clamping plate 12, the locking mechanism is fixed, and a connecting passage can be formed between the two flat steels through the alloy conductive layer on the upper clamping plate 11 and the lower clamping plate 12.
[0022] In a preferred embodiment, a first serrated pattern 13 is provided on the surface of the opposite side of the upper clamping plate 11 and the lower clamping plate 12, and an alloy conductive layer is also covered on the surface of the first serrated pattern 13.
[0023] The purpose of setting the first serration 13 is to increase the friction between the flat steel and the upper clamping plate 11 and the lower clamping plate 12, so that the flat steel is not easy to fall off.
[0024] In a preferred embodiment, through holes are located at the center of the upper clamping plate 11 and the lower clamping plate 12, and at the edges of the plates in a uniform radial direction. Four through holes can be provided, and four corresponding anti-loosening bolts 21 are also provided.
[0025] The purpose of this design is to increase the overall stability of the locking mechanism in the future.
[0026] In a preferred embodiment, an elastic washer 23 is provided between the upper clamping plate 11 and / or the lower clamping plate 12 and between the nut 22.
[0027] The elastic pad 23 can serve a relaxing purpose.
[0028] In a preferred embodiment, the upper clamping plate 11 and the lower clamping plate 12 are made of galvanized cast steel.
[0029] Example 2.
[0030] Further explanation in conjunction with Example 1;
[0031] In a preferred embodiment, a floating mechanism is provided below the upper clamping plate 11. The floating mechanism includes a mounting plate 31 provided below the upper clamping plate 11, a vertical plate 32 provided on the mounting plate 31, a ball 33 provided on the vertical plate 32, and a pressure plate 34 that contacts and cooperates with the ball 33. The pressure plate 34 has a groove that matches the ball 33, and the groove covers more than half of the surface area of the ball 33.
[0032] The purpose of setting up the floating mechanism is to allow the pressure plate 34 to fully contact the surface of the flat steel when the surface of the flat steel is uneven, thereby increasing the overall friction and making it less likely for the flat steel to fall off.
[0033] The first serration 13 and the second serration 35 can be made of a material harder than the flat steel, such as quenched steel, so that they can be pressed into the surface of the flat steel, making it less likely for the flat steel to come off.
[0034] When the groove covers more than half of the surface area of the sphere 33, the pressure plate 34 cannot detach from the sphere 33, and the pressure plate 34 can swing freely on the surface of the sphere 33.
[0035] In a preferred embodiment, a second serrated pattern 35 is provided below the pressure plate 34, and an alloy conductive layer covers the surfaces of the second serrated pattern 35, the pressure plate 34, the sphere 33, the upright plate 32, and the mounting plate 31.
[0036] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
