Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a special U type bolt of water purification car, includes bolt body 1, backing plate 2 and mount pad 3, the upper end of bolt body 1 is equipped with the fastening screw thread 4 of dextrorotation, mount pad 3 is located the top of bolt body 1 and is connected with 1 grafting of bolt body, the top of bolt body 1 still is equipped with lock nut 5, the upper surface of backing plate 2 is planar and the lower surface has seted up arc wall 6, backing plate 2 is located the surface of bolt body 1 and can dismantle with bolt body 1 and be connected, the opening width of arc wall 6 is greater than the diameter of bolt body 1, bolt body 1 is connected with 6 locks of arc wall.

Further improved ground, the terminal surface of backing plate 2 is trapezoidal shape and upper end width is greater than the lower extreme width, through adopting the terminal surface to be trapezoidal backing plate 2, improves backing plate 2 to the stability that the chassis longeron supported.
