At present, the anti-skid assembly is only provided with a butterfly washer on a cross-shaped groove pan head screw, the anti-skid effect is not ideal, the lifting is difficult, and the anti-skid assembly cannot deal with the conditions with high anti-skid requirements, so the improvement is needed.

SUMMERY OF THE UTILITY MODEL

A primary object of the utility model is to provide a cross recessed pan head screw and locking anti-skidding sub-assembly of butterfly washer compresses tightly through the spring and cooperates last butterfly washer, can make sub-assembly antiskid and locking performance more excellent, and the cross recessed on cross recessed pan head screw that moreover can be fine prevents the ash in the transportation to prevent that the dust from getting into wherein to influence the installation of cross recessed pan head screw at the back, can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a cross recess pan head screw and locking anti-skidding sub-assembly of butterfly washer, includes cross recess pan head screw, the pan head bottom of cross recess pan head screw is close to the inside both sides that left side position fixed connection has hollow box and all welds and has the gliding guide rail of confession slider, the welding has the connecting plate that bottom and montant are fixed between the slider, the bottom welding of montant has the top of ring plate and the pan head bottom of cross recess pan head screw to lean on right part fixedly connected with spring, the screw rod position of cross recess pan head screw has inserted butterfly washer.

Furthermore, a circular ring head with threads formed on the outer side wall is welded at the top end of the pan head of the cross-recessed pan head screw.

Further, the outer side wall of the ring head is in threaded connection with the inner side wall of the dustproof cover.

Furthermore, a through groove for the vertical rod to pass through is formed in the bottom end of the hollow box.

Compared with the prior art, the utility model discloses following beneficial effect has: the screw rod part of the cross-recessed pan head screw slowly enters a workpiece, the butterfly washer can upwards extrude the circular ring plate, the circular ring plate drives the vertical rod to upwards move, the vertical rod drives the connecting plate to upwards move, the connecting plate drives the sliding block to upwards move, the sliding block upwards slides along the guide rail, the linear movement of the circular ring plate can be well maintained, meanwhile, the spring is extruded, finally, the connecting plate is attached to the top end inside the hollow box, the spring is just in the best compression state, the spring utilizes the elasticity of the spring, pressure can be well applied to the circular ring plate, the circular ring plate transmits force to the butterfly washer, the workpiece is compressed at the moment, the stability of the installation of the cross-recessed pan head screw can be greatly enhanced, the anti-loosening and anti-skidding performance of the combined part can be better matched with the anti-loosening performance of the butterfly washer, the dustproof cover can be installed on the circular ring head through clockwise rotation in the transportation process, so that the cross-recessed pan head screw is covered, and dust is prevented from entering the cross-recessed pan head screw, and the installation of the cross-recessed pan head screw is prevented from being influenced later.
