Abstract
The utility model relates to an anti-loosening torque wrench which comprises a torque barrel, a through connection barrel and a sleeve. The through connection barrel is connected with the torque barrel in a sleeved mode, and the sleeve corresponds to the through connection barrel. A hammer, a spring compressed through pre-compression and a torque adjusting cover are arranged in the torque barrel and the through connection barrel from bottom to top, the torque adjusting cover is connected with the torque barrel through threads, an oblique upper sliding block is fixed to the hammer, an oblique lower sliding block matched with the upper sliding block is fixed in the through connection barrel, and a handle is fixed to the torque barrel. The anti-loosening torque wrench has the advantages of being small in size, light in weight, convenient to carry and suitable for iron tower aloft work.
Description
Technical field
The utility model relates to a kind of locking torque spanner.
Background technology
Steel tower is when mounted due to the randomness of tight power, bolt looseness can occur in running, cause the faults such as bolt falling, steel tower topple, in order to guarantee that bolt meets the requirements of pretightning force, be necessary to use torque spanner, but much heavier torque spanner in the market is, be not suitable for the steel tower work high above the ground, therefore be necessary to design a kind of light and handy torque wrench, reach the requirement of unified moment of torsion.The art of this patent adopts the combination of slide block and spring, has realized the effect of predetermined torque, has also played simultaneously and has impacted the effect of tightening, and keeps to greatest extent pretightning force, plays locking effect.
The utility model content
The purpose of this utility model is to provide a kind of locking torque spanner, and it can realize predetermined torque, and can play and impact the effect of tightening, and keeps to greatest extent pretightning force, plays locking effect.Possess volume little, lightweight, be convenient for carrying, be fit to the steel tower work high above the ground.
The utility model is taked following technical scheme:
A kind of locking torque spanner, it comprises torsion cylinder, switching cylinder with described torsion cylinder socket, and the sleeve corresponding with described switching cylinder, inner tup, the spring after precommpression, the torque adjustment lid of being provided with from bottom to top of described torsion cylinder and described switching cylinder, described torque adjustment lid is connected with described torsion cylinder by screw thread, is fixed with top shoe on described tup, described switching cylinder is inner is fixed with the sliding block supporting with described top shoe, and described torsion cylinder is fixed with handle.
As further improvement of the utility model, be provided with cannelure on described switching cylinder, described torsion cylinder is connected with circular trough on described switching sleeve by set bolt.
As the novel further improvement of this use, wherein mobilizable to be embedded in described switching cylinder inner for tup.
As further improvement of the utility model, described torque adjustment lid center is provided with adjustment hole.
The obtained beneficial effect of the utility model is:
Principle of the present utility model is, in screw connection structure, the first threads carry in screw thread 60% pretightning force, last screw thread is stressed hardly, so the bearing capacity of homogenising screw thread is the effective measures that delay bolt looseness.
On nut, the jacket casing of transferring is in upper cartridge with jacket casing, turning handle, when torsion hour, under the pressure-acting of spring, the relative sliding block of top shoe maintains static, torsion cylinder, switching cylinder, sleeve together rotate fastening nut.When torsion is enough large, the insufficient pressure of spring is to push down tup, top shoe on tup slides with respect to the sliding block on switching sleeve, torsion cylinder relatively rotates with respect to switching sleeve, because top shoe and sliding block mating surface are the inclined-plane, tup is along rising on the inclined-plane, when top shoe slips over sliding block, under the effect of spring, trickle distortion occurs in the downward hammering bolt of tup, the screw thread on bolt under the acting in conjunction of torsion and impulsive force, increased the contact area of flank, thereby slow down the loose of pretightning force, also reached default moment of torsion simultaneously.The torque adjustment lid is rotated down improves default moment of torsion, rotate up the torque adjustment lid and can reduce predetermined torque.To sum up, the utility model can be realized predetermined torque, and can play and impact the effect of tightening, and keeps to greatest extent pretightning force, plays locking effect.Possess volume little, lightweight, be convenient for carrying, be fit to the steel tower work high above the ground.

The specific embodiment
As shown in accompanying drawing 1,2 and 3, it comprises the torsion cylinder 3 that is fixed with handle 5 the utility model, switching cylinder 7 with described torsion cylinder 3 sockets, and the sleeve 10 corresponding with described switching cylinder 7, described torsion cylinder 3 inside are provided with the torque adjustment lid 1 that is threaded connection, described 1 bottom is provided with spring 2, be positioned at the tup 4 of spring 2 bottoms, the top of tup 4 is embedded with described torsion cylinder 3 inside, the bar section of tup 4 is embedded with described switching cylinder 7 inside, be fixed with top shoe 8 on described tup 4, described switching cylinder 7 inside are fixed with sliding block 9.Be provided with cannelure on switching cylinder 7, described torsion cylinder 3 is connected with circular trough on described switching sleeve 7 by set bolt 6.Complete torsion cylinder 3 with respect to the function in relative rotation of switching cylinder 7 by slip.
It can be hexangle type as connecting that the utility model transfer extend neck 7 can be provided with corresponding lines with the contact-making surface of corresponding sleeve 10, can be also that spirality is as above schemed, and can also be five jiaos or four jiaos of types, and the angle is conducive to sleeve more and uses at need in the position.In addition, switching cylinder 7 of the present utility model and sleeve 10 can be regulated according to the concrete condition of bolt, so that tup plays a role just.
The using method of the utility model practicality is as follows:
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
