Description
Technical field
The utility model belongs to fastening screw technical field, specifically, and the utility model is related to a kind of shearing resistance clamp screw
Nail.
Background technology
Holding screw is also known as branch head screw or set screw, is a kind of screw for specializing in fixed member relative position.
In use, holding screw is screwed in the screw of parts to be fixed, on the surface that another parts are pressed on the end of screw,
Even if previous parts are fixed on latter parts.But in the presence of mechanical oscillation or alternate load, trip bolt holds very much
Easily loosen, be easily caused holding screw and cut in the presence of shearing force, cause the damage of plant equipment or cause
Accident.
Utility model content
The utility model provides a kind of shearing resistance holding screw, improve the stability that trip bolt is tightened, it is to avoid in machinery
Occur loosening or cut in the presence of vibration or alternate load.
To achieve these goals, the technical scheme that the utility model is taken is：A kind of shearing resistance holding screw, including tightening
Screw body, the holding screw body is evenly arranged, institute provided with three rectangular openings between the rectangular opening in hexagonal angle
State in holding screw body and tighten sleeve pipe provided with interior hexagonal, and the interior hexagonal is tightened sleeve pipe and fixed with holding screw body and connected
Connect, interior hexagonal lock sleeve is provided with the holding screw body, and the interior hexagonal lock sleeve is rotated with holding screw body and connected
Connect.
It is preferred that, the interior hexagonal lock sleeve is provided with the square on three locking plates, and each locking plate and holding screw body
Shape hole is corresponding.
It is preferred that, the interior hexagonal lock sleeve is located at the outside that interior hexagonal tightens sleeve pipe.
It is preferred that, the locking plate uses spring steel material.
Beneficial effect using above technical scheme is：The shearing resistance holding screw, during use, is enclosed within die nut
Interior hexagonal is tightened on sleeve pipe, is fixedly connected because the interior hexagonal tightens sleeve pipe with holding screw body, by holding screw
Body is screwed into the screw of parts to be fixed, after holding screw body is tightened, and then changes other one die nut set
On interior hexagonal lock sleeve, it is connected because the interior hexagonal lock sleeve is rotated with holding screw body, the interior hexagonal lock sleeve
Provided with three locking plates, and each locking plate is corresponding with the rectangular opening on holding screw body, and hexagonal lock sleeve can band within institute
Locking plate motion, is stretched out from rectangular opening, is then caught in the screw of parts to be fixed in the good annular groove of prior car, prevents
Occur loosening in the presence of mechanical oscillation or alternate load or cut, improve the stability that trip bolt is tightened；Institute
The outside that interior hexagonal lock sleeve tightens sleeve pipe positioned at interior hexagonal is stated, spanner effect is mutually independent of each other；The locking plate uses spring
Steel matter, with certain deformation quantity, it is to avoid holding screw body is produced in the presence of mechanical oscillation or alternate load to be split
Trace.

Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the present utility model is made further in detail
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to it to implement.
As shown in Figure 1 to Figure 2, the utility model is a kind of shearing resistance holding screw, improves the stability that trip bolt is tightened,
Avoid and occur loosening in the presence of mechanical oscillation or alternate load or cut.
Specifically, as shown in Figure 1 to Figure 2, including holding screw body 1, as shown in Figure 1 and Figure 2, the holding screw
Body 1 is evenly arranged, the holding screw body provided with three rectangular opening 1-1 between the rectangular opening 1-1 in hexagonal angle
Sleeve pipe 10 is tightened provided with interior hexagonal in 1, and the interior hexagonal is tightened sleeve pipe 10 and is fixedly connected with holding screw body 1, it is described tight
Determine to be provided with interior hexagonal lock sleeve 11 in screw body 1, and the interior hexagonal lock sleeve 11 is rotated with holding screw body 1 and is connected.
As shown in Fig. 2 the interior hexagonal lock sleeve 11 is provided with three locking plates 12, and each locking plate 12 and holding screw sheet
Rectangular opening 1-1 on body 1 is corresponding.
As shown in Fig. 2 the interior hexagonal lock sleeve 11 is located at the outside that interior hexagonal tightens sleeve pipe 10.
The locking plate 12 uses spring steel material.
Specific works mode is illustrated with specific embodiment below：
The shearing resistance holding screw, during use, is covered with die nut and is tightened in interior hexagonal on sleeve pipe 10, because in described
Hexagonal is tightened sleeve pipe 10 and is fixedly connected with holding screw body 1, so holding screw body 1 to be screwed into the spiral shell of parts to be fixed
Kong Zhong, after holding screw body 1 is tightened, then changes other one and die nut is covered on interior hexagonal lock sleeve 11, because
The interior hexagonal lock sleeve 11 is rotated with holding screw body 1 and is connected, and the interior hexagonal lock sleeve 11 is provided with three locking plates 12,
And each locking plate 12 is corresponding with the rectangular opening 1-1 on holding screw body 1, hexagonal lock sleeve 11 can be with locking plate 12 within institute
Motion, stretches out from rectangular opening 1-1, is then caught in the screw of parts to be fixed in the good annular groove of prior car, it is therefore prevented that
Occur loosening in the presence of mechanical oscillation or alternate load or cut, improve the stability that trip bolt is tightened；It is described
Interior hexagonal lock sleeve 11 is located at the outside that interior hexagonal tightens sleeve pipe 10, spanner effect is mutually independent of each other；The locking plate 12 is used
Spring steel material, with certain deformation quantity, it is to avoid holding screw body 1 is produced in the presence of mechanical oscillation or alternate load
Raw slight crack.
The utility model is exemplarily described above in association with accompanying drawing, it is clear that the utility model is implemented not
Limited by aforesaid way, as long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or it is not improved, above-mentioned design of the present utility model and technical scheme are directly applied into other occasions, at this
Within the protection domain of utility model.
