Description

Bolt

Technical Field

The utility model belongs to the technical field of the metal product technique and specifically relates to a bolt.

Background

A bolt is a mechanical part, and a cylindrical threaded fastener matched with a nut. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. Because some large-scale machines of present use more, and the size is all inequality, when these large-scale machines need to be maintained, dismantle these bolts that differ in size and need carry the bolt spanner of multiple equidimension, if in case forget to carry bolt spanner or just can not dismantle or installation work to the bolt in the case of the size difference to make the staff of maintenance machine bring unnecessary trouble in the maintenance process.

SUMMERY OF THE UTILITY MODEL

To the not enough in the background art, the utility model provides a bolt to overcome above defect.

The utility model provides a technical scheme that its technical problem adopted is:

a bolt comprises a screw and a nut which are integrally arranged, wherein a rod groove communicated with the inside of the screw is formed in the upper surface of the nut, a torsion bar is arranged in the rod groove, a limit block is symmetrically distributed at one end, away from the screw, of the nut and surrounds the rod groove, a stroke gap is formed at one end, close to the nut, of the limit block, an adjusting gap is formed in one side, close to the torsion bar, of the limit block, a clamping block is arranged in the stroke gap, a pressure spring is arranged between one end, away from the torsion bar, of the clamping block and the stroke gap, and a stirring lug matched with the adjusting gap and with one end extending out of the limit block is integrally;

one end of the torsion bar extends out of the nut and is provided with an auxiliary through hole, the two sides of the torsion bar are respectively provided with a clamping through groove which is arranged diagonally and matched with the clamping block, one side of the torsion bar is provided with a placing groove, a torsion bar is arranged in the placing groove, and one end of the placing groove, which is close to the auxiliary through hole, is provided with a rubber elastic belt at the opening of the placing groove.

The cross-section of the screw is square and is attached to the inner wall of the rod groove.

The two sides of one end of the torsion bar, which is far away from the nut, are provided with assistant pulling lugs.

The opening of the adjusting gap is smaller than the opening of the stroke gap.

Owing to adopted above-mentioned technical scheme, a bolt is through setting up the pole groove and set up the screw rod wherein and avoided the trouble of carrying the instrument when dismantling or installing the bolt, and the cooperation through setting up stopper and card and putting piece and compression spring realizes the card of screw rod and puts simultaneously, avoids it to break away from the pole groove, the utility model discloses the mechanism is simple, simple to operate for the bolt is even if also can normally be installed or dismantle under the condition that does not carry bolt spanner.

Detailed Description

The present invention will be described in more detail with reference to the following examples, which are illustrated in the accompanying drawings. This example is merely a description of the best mode of carrying out the invention and is not intended to limit the scope of the invention in any way.

As shown in fig. 1 to 2, a bolt comprises a screw and a nut which are integrally arranged, wherein a rod groove communicated with the inside of the screw is formed in the upper surface of the nut, a torsion bar is arranged in the rod groove, limiting blocks which are symmetrically distributed are arranged at one end, away from the screw, of the nut around the rod groove, a stroke gap is formed at one end, close to the nut, of each limiting block, an adjusting gap is formed at one side, close to the torsion bar, of each limiting block, a clamping block is arranged in each stroke gap, a pressure spring is arranged between one end, away from the torsion bar, of each clamping block and each stroke gap, and a toggle bump which is matched with each adjusting gap and one end of which extends out of;

The two sides of one end of the torsion bar, which is far away from the nut, are provided with assistant pulling lugs. The part of the pulling-assisting convex block, which is close to one end of the nut and connected with the torsion bar, is arc-shaped, so that a force assisting point is provided, and the torsion bar can be conveniently pulled out from the bar groove by the force applied by hands.

The opening of the adjusting gap is smaller than the opening of the stroke gap.

The specific working principle is as follows: when the bolt needs to be screwed out or installed, firstly, the clamping block clamped in the clamping through groove moves towards the direction of the pressure spring through the poking lug on one side of the screw rod, so that the screw rod is separated from the clamping position, and the position of the clamping through groove is close to the auxiliary through hole and is matched with the clamping block to clamp and fix the screw rod;

further, the screw rod is pulled out by pinching the pull-assisting convex block at one end of the screw rod, which extends out of the screw cap, until the clamping block at the other side of the screw rod is clamped into the clamping through groove under the action of the pressure spring, and at the moment, the rest part of one end of the screw rod, which is far away from the auxiliary through hole, is in the rod groove; the clamping through groove is positioned at the other side of the screw rod and is far away from the auxiliary through hole, and the whole placing groove is separated from the rod groove; the limit of the rubber elastic band losing the rod groove is reset, and one end of the torsion bar is ejected out of the rod groove;

furthermore, the torsion bar is taken out, one end of the torsion bar is inserted into the auxiliary through hole, the screw rod is rotated through the torsion bar, the screw rod drives the bolt to rotate through the matching with the rod groove, force application is facilitated, and an installation tool is not needed.

It is to be understood that the above examples are merely illustrative for clarity of description and are not limiting on the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the invention.
