Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1 to 3, the round thread structure with guiding function of this embodiment includes a screw 1 and a nut 2, the screw 1 and the nut 2 are detachably connected, a transition thread 3 with guiding function is provided at an end of the screw 1 opposite to the nut 2, and the transition thread 3 is a thread structure.

The improvement is as follows: as shown in fig. 1 and 2: can dismantle the connection between screw 1 and the nut 2, the one end of screw 1 back to nut 2 is provided with the transition tooth 3 that has the guide effect, and transition tooth 3 is the setting of circle helicitic texture, and the circle screw thread can normally close with treating to close the part soon, therefore can play better guide effect.

On the basis of the above embodiment, one end of the screw 1, which faces away from the transition tooth 3, is provided with the threaded connecting rod 4, the threaded connecting rod 4 and the screw 1 are integrally formed, the nut 2 is provided with the threaded connecting groove 5 which is used for being matched with the threaded connecting rod 4, the part of the threaded connecting rod 4, which is connected with the screw 1, is provided with the empty groove 6, the empty groove 6 is internally used for filling the shockproof piece 7, and the shockproof piece 7 is arranged in an annular structure.

The improvement is as follows: as shown in fig. 3: one end of the screw 1, which is opposite to the transition tooth 3, is provided with a threaded connecting rod 4, the nut 2 is provided with a threaded connecting groove 5 matched with the threaded connecting rod 4, and during production, different dies can be adopted for synchronous production (in the prior art, most of the screw 1 and the nut 2 are integrally formed, the screw 1 is firstly punched in the dies, and then the nut 2 is processed, so that the consumed time in the processing process is long), in the embodiment, the screw 1 and the nut 2 can be detachably arranged, the screw 1 and the nut 2 are separately processed, the processing time and the processing cost can be effectively saved, the screw 1 is provided with the threaded connecting rod 4, the nut 2 is provided with the threaded connecting groove 5, after the screw 1 and the nut are installed and processed, the threaded connecting rod 4 can be screwed into the threaded connecting groove 5, and the connecting part of the threaded connecting rod 4 and the screw 1 is provided with a hollow groove 6, and set up shockproof piece 7 on threaded connection pole 4, shockproof piece 7 with can place in the dead slot 6 inside, through the setting of shockproof piece 7, when can effectually preventing vibrations, threaded connection pole 4 and threaded connection groove 5 can break away from each other.

On the basis of the above embodiment, the shock-proof sheet 7 may be made of a rubber material.

The improvement is as follows: rubber has certain elasticity, installs on threaded connection pole 4, screws into threaded connection groove 5 when screw 1 connecting rod, when the external production vibrations, and certain vibrations power can be fallen in buffering by shockproof piece 7 to prevent that screw 1 is not hard up.

On the basis of the above embodiment, the nut 2 is provided with a receiving groove 8 for receiving the anti-vibration piece 7.

The improvement is as follows: the holding tank 8 can effectually hold the shockproof piece 7, makes the screw 1 and the nut 2 be connected inseparabler.

On the basis of the above embodiment, the transition tooth 3 is a complete round thread with two turns.

The improvement is as follows: the round thread enables the screw 1 to automatically and normally screw in when the screwing-in deviation occurs.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
