Detailed Description

The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.

As shown in fig. 1-3, the present invention discloses a composite cross slot locking bolt, comprising: screw rod 1, 1 tops of screw rod are provided with nut 2, and 1 cross-sections of screw rod are the ratchet form, and 1 outer wall of screw rod is provided with locking device 3 through cup jointing, and locking device 3 is used for avoiding producing behind the bolt-up not hard up.

Further, as shown in fig. 2 and fig. 3, the locking device 3 includes a base 31 which is disposed on the outer wall of the screw rod 1 through a thread, a cavity 32 which is opened toward the screw rod 1 is disposed on the inner wall of the base 31, a pawl 33 is disposed in the cavity 32 through a rotating shaft, the other end of the pawl 33 is attached to the outer wall of the screw rod 1, a connecting rod 34 is disposed at one end of the pawl 33 away from the screw rod 1, a shift lever 35 is disposed at the top end of the connecting rod 34, a slide 321 which is communicated with the top end of the base 31 is disposed at the top end of the cavity 32, and the top end of the shift lever 35 passes through the slide 321 and extends to the base 31.

Further, as shown in fig. 3, a stop block 36 is disposed at the counterclockwise opening of the cavity 32, and a pressure spring 37 is disposed between the stop block 36 and the connecting rod 34.

Further, as shown in fig. 1, a rubber gasket 4 is provided at the bottom end of the base 31.

Further, as shown in fig. 4, the bottom end of the rubber gasket 4 is uniformly provided with salient points.

The working principle is as follows: through fixing locking Assembly 3 and junction earlier, again with screw rod 1 for with base 31 clockwise rotation, pawl 33 is undulant along with screw rod 1 outer wall when the bolt is rotatory, until laminating of base 31 top and nut 2 bottom, in the rotation process, pressure spring 37 keeps laminating through connecting rod 34 drive pawl 33 other end and screw rod 1 outer wall throughout, when screw rod 1 produces not hard up, pawl 33 other end withstands ratchet form notch department, produce locking state, make screw rod 1 unable continuation rotation, increase the resistance with the link through rubber packing ring 4 simultaneously, when the screw thread setting of bolt 1 needs to be relieved, stir driving lever 35 along slide 321 anticlockwise, driving lever 35 drives pawl 33 through connecting rod 34 and rotates, until in pawl 33 withdraws cavity 32, it can to relieve bolt thread setting simultaneously.

Compared with the prior art, the cross section of the screw rod is in the shape of the ratchet wheel, and the screw rod is matched with the pawl of the locking device, so that the bolt cannot be loosened after being fastened.
