Abstract
This utility model is related to screw technique field, more particularly to a kind of holding screw.A kind of holding screw includes threaded shank, and one end of threaded shank is provided with operating portion, and the other end of threaded shank is provided with a glass tail, and the cup tail includes the side of taper, and side is provided with multiple double wedges for increasing coefficient of friction；The bottom of cup tail is provided with shrinkage pool, and auxiliary location structure is provided with shrinkage pool.This utility model is by arranging auxiliary location structure in shrinkage pool, so that holding screw, is difficult to loosen when in use, it is easy to use.
Description
Technical field
This utility model is related to screw technique field, more particularly to a kind of holding screw.
Background technology
Holding screw is a kind of positioning mounting, in particular for fixing two objects；When fixed, holding screw is passed through
The screw of one of object, enters in the blind hole of another object；In use, as two objects are not using
Unusual synchronization, so as to produce relative vibration, and current holding screw typically merely by threaded connection by two objects
It is attached, without positioning, fastening structure, causes holding screw easily to occur loosening.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, there is provided a kind of holding screw, the holding screw exist
During use, it is difficult to loosen.
The technical scheme that this utility model is adopted for achieving the above object for：
A kind of holding screw, including threaded shank, one end of threaded shank are provided with operating portion, and the other end of threaded shank is provided with cup
Tail, the cup tail include the side of taper, and side is provided with multiple double wedges for increasing coefficient of friction；The bottom of cup tail is provided with recessed
Hole, is provided with auxiliary location structure in shrinkage pool.
Further, auxiliary location structure includes the salient point for being arranged at shrinkage pool side.
Further, auxiliary location structure includes the elastic component being arranged in shrinkage pool.
Further, auxiliary location structure includes stage clip and thimble, and one end of stage clip is connected with shrinkage pool medial surface, stage clip
The other end is connected with thimble.
Further, operating portion includes inner hexagonal hole or cross recess.
The beneficial effects of the utility model are：This utility model by arranging auxiliary location structure in shrinkage pool so that
Obtain holding screw when in use, be difficult to loosen, it is easy to use.
Description of the drawings
Fig. 1 is a kind of partial schematic sectional view of the present utility model.
Schematic diagrams of the Fig. 2 for another visual angle of Fig. 1.
Fig. 3 is another kind of partial schematic sectional view of the present utility model.
Reference is：
1 --- threaded shank；2 --- cup tail；3 --- operating portion；4 --- double wedge；5 --- shrinkage pool；6 --- stage clip；7——
Thimble；51 --- salient point.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is further described.
Embodiment 1：Referring to Fig. 1, Fig. 2.
A kind of holding screw, including threaded shank 1, one end of threaded shank 1 are provided with operating portion 3, and the other end of threaded shank 1 is provided with
Cup tail 2, the cup tail 2 include the side of taper, and side is provided with multiple double wedges 4 for increasing coefficient of friction；The bottom of cup tail 2
Shrinkage pool 5 is provided with, in shrinkage pool 5, auxiliary location structure is provided with.
When in use, in the blind hole into another object, the side of cup tail 2 is abutted cup tail 2 the technical program with which,
And formed and certain compress power.When occur vibration when, due to the resistance of double wedge 4 it is larger, such that it is able to effectively prevent threaded shank 1
Rotation, holding screw loosen.Secondly auxiliary location structure is provided with shrinkage pool 5, it is also possible to further increase locating effect.
Further, auxiliary location structure includes the salient point 51 for being arranged at 5 side of shrinkage pool.
When bottom cooperation of the shrinkage pool 5 with blind hole, salient point 51 can play the effect for increasing frictional force.Preferably, salient point
51 in tip setting.
Referring to Fig. 3, further, used as another kind of form, which includes the elasticity being arranged in shrinkage pool 5 to auxiliary location structure
Part.
When mounted, elastic component is offseted with blind hole, and is deformed upon；Elastic component applies thrust to threaded shank 1,
Further, auxiliary location structure includes stage clip 6 and thimble 7, and one end of stage clip 6 is connected with 5 medial surface of shrinkage pool, pressure
The other end of spring 6 is connected with thimble 7.
After arranging stage clip 6 and thimble 7, when holding screw is installed, thimble 7 is offseted with the bottom surface of blind hole, and stage clip 6 is compressed
And produce certain thrust, so that between the ridge of the ridge of threaded shank 1 and two screws, have larger extruding force,
Threaded shank 1 needs to overcome larger frictional force relative to two screw rotations.Its easy loosening is avoided so as to a progressive step.
Further, operating portion 3 includes inner hexagonal hole or cross recess.
Operating portion 3 is set to into inner hexagonal hole, cross recess form, is easy to operation.Can certainly be flat recess etc..It is preferred that
Ground, operating portion 3 are provided with perforation or blind hole；Pluggable screw driver or other connecting rods, facilitate rotation process portion.
This utility model has been made to explain, it will be understood by those within the art that, can be new to this practicality
The technical scheme of type is modified or equivalent, without deviating from the spirit and scope of technical solutions of the utility model.
