Along with the development of economy, the automobile becomes the vehicle of most people's trip, and current automobile when carrying out the dismantlement of tire, often the producer requires to carry out the dismantlement of wheel hub bolt with torque wrench, but current maintenance shop often operates in violation of rules and regulations, does not use torque wrench, leads to the wheel hub bolt to be twisted off for it is troublesome to have caused the car owner.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems and provide a breakage-proof durable bolt.
The utility model achieves the purpose through the following technical scheme, and the breakage-proof durable bolt comprises a bolt body, wherein the bolt body comprises a threaded part and an operating part, a transmission protrusion is arranged at one end, away from the threaded part, of the threaded part, a transmission groove is formed in the operating part, the transmission groove is matched with the transmission protrusion, and a torque assembly for keeping the transmission groove and the transmission protrusion attached is arranged at one end, away from the threaded part, of the operating part.
Through adopting above-mentioned technical scheme, rotate the operation portion during the use for the transmission groove of operation portion supports presses the transmission protruding, thereby twists screw portion into the screw, after screw portion twists targets in place, when the transmission groove supported and presses the transmission protruding, makes transmission groove and transmission protruding production relative slip, can make the operation portion by reverse jack-up, thereby through the torsion subassembly, makes the operation portion can't transmit torsion to screw portion, thereby protection screw portion can not be twisted off.
Preferably, the moment assembly comprises a fixing piece and an elastic piece, one end of the fixing piece is fixedly connected with the threaded portion, and the other end of the fixing piece is mutually abutted against the operating portion through the elastic piece.
By adopting the technical scheme, the fixing piece fixes the operating part on the threaded part through the elastic piece, and the elastic piece enables the operating part and the threaded part to generate relative movement by compressing the elastic piece after the threaded part reaches the screwing part, so that the operating part cannot transmit power to the threaded part, and the threaded part is protected from being unscrewed.
Preferably, the transmission protrusion is in the shape of ratchet teeth.
Through adopting above-mentioned technical scheme, the transmission of ratchet form is protruding for when screwing up, can make operating portion and screw thread portion produce through the ratchet inclined plane and slide, and prevent that screw thread portion from being twisted off, and when unscrewing, can press each other through the protruding face of ratchet, thereby better unscrew screw thread portion.
Preferably, a shock absorbing pad is arranged at one end of the operating part close to the threaded part.
Through adopting above-mentioned technical scheme, the operating portion passes through the shock pad and the contact of wheel hub for the operating portion is difficult to be damaged by the vibration when daily use.
Compared with the prior art, the utility model has the beneficial effects that: support through the elastic component and press the operation portion for transmission groove and transmission are protruding to support each other and press, make the operation portion can be through supporting pressing screw portion, thereby drive screw portion and twist into the screw, and after screw portion was screwed up, the unable screw portion that drives when the transmission groove supported pressing the transmission is protruding, makes transmission groove and transmission protruding production slip, makes the operation portion by jack-up, thereby makes the operation portion unable with power transmission to screw portion.

Detailed Description
In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the designated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the anti-breaking durable bolt comprises a bolt body, the bolt body comprises a thread portion 1 and an operating portion 2, one end, far away from the thread, of the thread portion 1 is provided with a transmission protrusion 3, the transmission protrusion 3 is in a ratchet shape, a transmission groove 4 is formed in the operating portion 2, the transmission groove 4 is matched with the transmission protrusion 3, one end, far away from the thread portion 1, of the operating portion 2 is provided with a moment assembly for keeping the transmission groove 4 and the transmission protrusion 3 attached, the moment assembly comprises a fixing member 5 and an elastic member 6, one end of the fixing member 5 is fixedly connected with the thread portion 1, and the other end of the fixing member is abutted against the operating portion 2 through the elastic member 6.
When the adjustable torsion wrench is used, the fixing part 5 is firstly adjusted, so that the compression degree of the elastic part 6 is adjusted, so that the abutting pressure between the transmission protrusion 3 and the transmission groove 4 is changed, so that the size of the torsion is preset, when the thread part 1 is screwed into a screw hole through the operation part 2, the operation part 2 can transmit the rotation force to the transmission protrusion 3 through the transmission groove 4, so that the transmission protrusion 3 rotates, so that the thread part 1 rotates, when the thread part 1 is screwed into a screwing state, the resistance of the thread part 1 is increased, so that when the transmission groove 4 transmits the rotation force to the transmission protrusion 3, because of the resistance blockage, the transmission groove 4 cannot transmit the rotation force, so that the transmission groove 4 and the transmission protrusion 3 slip, so that the transmission groove 4 is lifted upwards along the inclined plane of the transmission protrusion 3, so as to compress the elastic part 6, so that the operation part 2 cannot transmit the rotation force to the thread part 1, thereby avoiding the screw part 1 from being twisted off. And when needs are twisted out with screw thread portion 1, reverse twist moves operation portion 2 for transmission groove 4 supports presses the vertical face of ratchet, through the support of vertical face, makes the condition that the transmission groove 4 can not appear skidding with transmission arch 3, thereby better lets screw thread portion 1 twist out the screw. The end of the operating part 2 close to the thread part 1 is provided with a shock absorption pad 7, and the shock absorption pad 7 reduces the vibration of the operating part 2, thereby prolonging the service life of the utility model.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
