Various locknut fasteners and other fasteners circulated in the market at present cannot achieve the stability of a tightening structure and the permanent function of no loosening in the environment, so that the practicability of the equipment in the use process is restricted.
Disclosure of Invention
In order to solve the problems, the utility model discloses a novel anti-loosening fastener, wherein a first locking piece and a second locking piece which act on a screw rod are inserted into a conical hole through a conical table, so that friction force is further increased, and locking stability is ensured.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a novel anti-loosening fastener comprises a screw rod, a first locking piece and a second locking piece;
the middle part of the first locking piece is provided with a first threaded hole and a conical hole which are communicated, and the outer side of the first locking piece is provided with a first screwing part;
the middle part of the second locking piece is provided with a second threaded hole, the outer side of the second locking piece is provided with a conical table and a second screwing part, and the conical table is matched with the contour of the conical hole;
the first locking piece is connected with the screw rod through a first threaded hole, the second locking piece is connected with the screw rod through a second threaded hole, and the conical table is inserted into the conical hole.
Preferably, the conical table is provided with a locking notch along the axis of the conical structure of the conical table.
Preferably, the first screw portion and the second screw portion have the same structure.
Preferably, the first screwing part is of an outer hexagonal structure.
Preferably, the inner side wall of the conical hole is of a smooth structure.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the first locking piece and the second locking piece are inserted into the tapered hole through the tapered table under the action of the screw rod, the diameter of the tapered table is gradually reduced under the pressure of the tapered hole, and the tightening allowance is released through the locking notch, so that the first locking piece and the second locking piece are tightly matched with the screw rod, the anti-loosening and anti-blocking friction force is improved, and the practicability is enhanced.

Detailed Description
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
In order to better understand the embodiments of the present application, the following description will clearly and completely describe the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
1-5, the novel anti-loosening fastener comprises a screw 1, a first locking piece 2 and a second locking piece 3;
the middle part of the first locking piece 2 is provided with a first threaded hole 21 and a conical hole 22 which are communicated, and the outer side of the first locking piece 2 is provided with a first screwing part 23;
a second threaded hole 31 is formed in the middle of the second locking member 3, a conical table 32 and a second screwing part 33 are arranged on the outer side of the second locking member 3, and the conical table 32 is matched with the contour of the conical hole 22;
the first locking member 2 is connected with the screw 1 through a first threaded hole 21, the second locking member 3 is connected with the screw 1 through a second threaded hole 31, and the conical table 32 is inserted into the conical hole 22.
The conical table 32 is provided with locking notches 34 along the axis of the conical structure, and the number of the locking notches 34 is determined according to the diameter of the screw 1, and is generally four.
The first screw 23 and the second screw 33 have the same structure.
The first screwing part 23 has an outer hexagonal structure.
The inner side wall of the tapered hole 22 is of a smooth structure (not shown), and the tapered table 32 is inserted into the tapered hole 22 to generate diameter reduction deformation when being pushed by the torque of the screw.
The traditional nuts (or other fasteners) are tightly locked by single locking or multiple nuts, namely, radial surfaces which are not contracted on the transverse surfaces or partial surfaces of the screw 1 wire openings are tightly jointed, the stressed friction surfaces are small, and the generated counter resistance is also small; and realize through first retaining member 2 and second retaining member 3 mutually supporting in the device of this application, toper platform 32 and bell mouth 22 realize interference fit under screw rod 1's effect, and the frictional resistance face that produces is greater than traditional all kinds of lock nut and other fasteners far away to need not to install the spring pad additional, the functional strong.
