Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of backing-up screw group proposed
Part.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of stop screw component is designed, including nail rod and the circular head of a nail, the head of a nail are vertically fixed on one end of nail rod,
The nail rod is equipped with the first screw thread, the first nut of regular pentagon is arranged in the nail rod, first nut is close to nail
The side of bar is equipped with the second screw thread to match with the first nut, and first nut is far from concentric solid on one end of the head of a nail
Surely it is equipped with the protrusion of truncated conical shape, and nail rod, through protrusion setting, the protrusion is set far from fixing sleeve equidistant on the side of nail rod
Have plastic ring, be arranged with the second nut of regular pentagon in the nail rod, and the setting of the first nut the second nut and the head of a nail it
Between, second nut is equipped with the third screw thread to match with the first nut close to the side of nail rod, and second nut leans on
The second groove of truncated conical shape is offered on one end of nearly first nut, and protrusion is inserted into the second groove, the plastic ring
Side far from protrusion is in contact with the second groove.
Preferably, the head of a nail is far from opening up the first groove cruciferous on the side of nail rod, in first groove
It is coated with wearing layer, the wearing layer is made of silica material.
Preferably, engineering plastics, the engineering plastic are coated on first screw thread, the second screw thread and third screw thread
Material is made of polyimide material.
The utility model proposes a kind of stop screw component, beneficial effect is: the first nut and the second nut are mutual
Cooperation is mounted in nail rod, and the engineering plastics on the first screw thread, the second screw thread and third screw thread are capable of increasing between threaded engagement
Frictional force, the second groove on the second nut moves closer to the protrusion on the first nut, the second groove will be to modeling during installation
The case where feed ring generates extruding, increases the frictional force between the first nut and the second nut, prevents loosening.The utility model
It is easy to use, there is good anti-loosing effect.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of stop screw component structural schematic diagram；
Fig. 2 be the utility model proposes a kind of stop screw component Fig. 1 in enlarged drawing at A.
In figure: nail rod 1, the head of a nail 2, the first groove 3, the first screw thread 4, the first nut 5, raised 6, second screw thread 7, the second spiral shell
Female 8, third screw thread 9, the second groove 10, plastic ring 11.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of stop screw component, including nail rod 1 and the circular head of a nail 2, the head of a nail 2 are vertically fixed on nail rod
On 1 one end, the head of a nail 2 opens up the first groove 3 cruciferous on the side far from nail rod 1, is coated in the first groove 3 wear-resisting
Layer, wearing layer are made of silica material, and wearing layer enhances the surface strength of the first groove 3, extend the service life of device.
Nail rod 1 is equipped with the first screw thread 4, the first nut 5 of regular pentagon is arranged in nail rod 1, the first nut 5 is close to nail
The side of bar 1 is equipped with the second screw thread 7 for matching with the first nut 5, concentric on first one end of nut 5 far from the head of a nail 2
It is fixed with the protrusion 6 of truncated conical shape, and nail rod 1 is arranged through protrusion 6, equidistant fixing sleeve on raised 6 sides far from nail rod 1
Equipped with plastic ring 11, plastic ring 11 is made of polyimide material, and rigidity is big, and creep is small, high mechanical strength, heat-resist, electricity
Good insulating.
Be arranged with the second nut 8 of regular pentagon in nail rod 1, and the setting of the first nut 5 the second nut 8 and the head of a nail 2 it
Between, the second nut 8 is equipped with the third screw thread 9 that matches with the first nut 5 close to the side of nail rod 1, and the second nut 8 is close to the
The second groove 10 of truncated conical shape is offered on one end of one nut 5, and protrusion 6 is inserted into the second groove 10, plastic ring 11
