Furthermore, the inner side wall of the gasket is fixedly provided with four sliding pins, the rod body is provided with a sliding groove located in the threaded section, and the sliding pins are connected to the sliding groove in a sliding mode.

By adopting the technical scheme, the sliding track of the gasket can be limited through the sliding connection between the sliding pin and the sliding groove, and the sliding stability of the gasket is ensured.

Furthermore, the two ends of the rod body are provided with grooves, fixing rods are fixedly installed between the inner walls of the two sides of each groove, and the outside of each fixing rod is rotatably provided with a butt joint plate.

Through adopting above-mentioned technical scheme for the screw thread connecting rod can apply the clamp force to extending to the other end of connecting part to closing the connecting part, reduces screw thread connecting rod screw thread atress, improves life.

Further, the groove is rectangular and extends from the end surface of the shaft toward the middle of the shaft.

Through adopting above-mentioned technical scheme for the relative angle of rotation adjustment and screw thread section that the board can be nimble to the fender that is located recess inside.

Further, one end of the abutting plate extends to the outside of the groove.

Through adopting above-mentioned technical scheme, make the board of keeping to can rotate down the perpendicular to the pole body, and with form T shape shaft-like between the pole body, accomplish the butt of keeping away from a side of gasket locking to the connecting part.

Further, the fixing rod is positioned inside the groove at a position close to the end of the rod body.

Through adopting above-mentioned technical scheme, make the butt plywood can satisfy both ends length the same, guarantees the butt plywood extends to close the stress surface that contacts the same.

This threaded connecting rod carries out the screw pretension to threaded connecting rod and connecting part's port through setting up gasket and nut, accomplishes the locking to improve the stability behind the threaded connection, set up the dead lever in addition and come the two-way locking to connecting part to the butt plate, realize improving the locking effect, and block the protection to threaded connecting rod junction through the gasket, can reduce threaded connecting rod connection tip and expose rusty phenomenon, improve threaded connection's stability and life.

Detailed Description

Referring to fig. 1, the threaded connecting rod in this embodiment includes a rod body 1, wherein thread segments 2 are formed on two ends of the rod body 1 through a high-precision thread rolling process, and the threaded connecting rod can complete threaded connection between two mechanical parts through the thread segments 2 formed on the two ends of the rod body 1.

Referring to fig. 2, in the present embodiment, a gasket 3 is slidably mounted on an outer portion of the rod body 1, four sliding pins 4 are fixedly mounted on an inner side wall of the gasket 3, a sliding groove 5 located in the threaded section 2 is formed in the rod body 1, and the sliding pins 4 are slidably connected to the sliding groove 5, so that a sliding track of the gasket 3 can be limited through sliding connection between the sliding pins 4 and the sliding groove 5, and stability of sliding of the gasket 3 is ensured.

Through gasket 3 along 1 horizontal slip of pole body, can stop threaded section 2 of junction when gasket 3 is accomplished to laminate in the connecting part surface, reduce the rusty possibility of threaded connection in threaded section 2 of connecting part department, reduce the problem that threaded section 2 permanent locking can't be taken apart.

In order to complete the locking of the rod body 1 and the connecting part, a nut 6 which is in threaded connection with the threaded section 2 is slidably mounted on the outer portion of the rod body 1, the nut 6 can move along the outer portion of the threaded section 2 under rotation, and when the nut is attached to the gasket 3, the locking of the threaded section 2 relative to the connecting part is completed.

The both ends of the pole body 1 in this embodiment are provided with grooves 7, the grooves 7 are rectangular and extend from the end surface of the pole body 1 to the middle of the pole body 1, fixing rods 8 are fixedly arranged between the inner walls of the two sides of the grooves 7, and the outside of the fixing rods 8 is rotatably provided with a butt joint plate 9.

Wherein, the one end of the board 9 that supports extends to the outside of recess 7 for the board 9 that supports can be perpendicular to pole body 1 under rotating, and form the T shape between the pole body 1 and be shaft-like, accomplish the butt joint locking of connecting element keeping away from 3 a side of gasket.

It is supplementary to explain that dead lever 8 is located the position that recess 7 is inside to be close to the tip of pole body 1 for it is the same that the length of both ends can be satisfied to the board 9 that supports, guarantees that the board 9 that supports extends to close the stress surface that contacts is the same.

The working principle of the above embodiment is as follows:

when using, through the threaded section 2 with the 1 both ends of pole body and the mutual threaded connection of screw hole of connecting part, simultaneously will run through to the 2 interior butt plate 9 rotations of screw section of connecting part opposite side and expand, backspace screw section 2 to butt plate 9 butt joint part, pass through sliding gasket 3 this moment, make gasket 3 pass through the relative sliding direction between sliding pin 4 and spout 5, accomplish and laminate in the connecting part surface, the slip is located 1 outside nut 6 to the screw section 2 of pole body, through rotating nut 6, make nut 6 extrude under 2 threaded connection with the screw section and support and close in gasket 3, accomplish the locking to the threaded connection rod.
