Abstract
The utility model discloses a kind of self threading pins of damping, including the head of a nail, screw rod, ailhead, damping spring, the first gasket, head of a nail lower end connecting screw, the screw rod lower end is equipped with ailhead, the first gasket is additionally provided between the head of a nail and screw rod, the lower end of first gasket is connected with damping spring.A kind of self threading pin of damping of the utility model; solve the problems, such as that existing self threading pin shakes strong, easily shaking when being screwed into; damping spring is equipped in the outside of screw rod; damping spring is absorbable, weakens the vibration that self threading pin is generated when self tapping is screwed into; the problem of fracture, fragmentation will not occur for protection self threading pin rivet nut, prolongs the service life.
Description
[technical field]
The utility model relates to a kind of technical field of hardware component, the technology of especially a kind of self threading pin of damping is led
Domain.
[background technique]
Self-tapping screw is voluntarily to attack the one kind for drilling out negative thread joined together in the prebored hole of metal or nonmetallic materials to have
Threaded fasteners.Due to its voluntarily form or can tapping cooperate its screw thread, closing in group has high anti-loose ability, and can be with
Handling.Its size on small shape screw, screw type, head dummy attack and bore performance high-tensile strength on engineering purposes, single-piece, and unilateral group
It is promising to close characteristic.Door and window is generally used for, on iron sheet.On the market common some self threading pins when self tapping is screwed into be easy because
Shaking causes to connect untight problem, or even because shaking the too strong structure for having damaged screw itself, to cause safety accident.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of self threading pin of damping, has and subtracts
Weak shock moves, prevents the effect loosened.
To achieve the above object, the utility model proposes a kind of self threading pin of damping, including the head of a nail, screw rod, ailhead, subtract
Spring, the first gasket are shaken, head of a nail lower end connecting screw, the screw rod lower end is equipped with ailhead, between the head of a nail and screw rod
It is additionally provided with the first gasket, the lower end of first gasket is connected with damping spring.
Preferably, the screw rod includes first body of rod and second body of rod, second body of rod is located at the outer of first body of rod
End, first body of rod and second body of rod are an integral structure, and second body of rod lateral surface is equipped with screw thread, the damping bullet
Spring is located at the outside of first body of rod.
Preferably, the lateral surface of the damping spring is equipped with the second gasket, second gasket is cirque structure,
The bottom end of second gasket is located at the junction of first body of rod and second body of rod.
Preferably, the tapered structure of ailhead.
The utility model has the beneficial effects that a kind of self threading pin of damping of the utility model, solves existing self threading pin and exists
Strong, easy the problem of shaking is shaken when being screwed into, and is equipped with damping spring in the outside of screw rod, damping spring is absorbable, weakens self threading pin
The problem of vibration generated when self tapping is screwed into, fracture, fragmentation will not occur for protection self threading pin rivet nut, prolong the service life.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of the self threading pin of damping of the utility model.
In figure: the 1- head of a nail, 2- screw rod, 3- ailhead, 4- damping spring, the first gasket of 5-, first body of rod of 21-, the second bar of 22-
Body, the second gasket of 40-, 220- screw thread.
[specific embodiment]
Refering to fig. 1, a kind of self threading pin of damping of the utility model, including the head of a nail 1, screw rod 2, ailhead 3, damping spring 4,
One gasket 5, the 1 lower end connecting screw 2 of the head of a nail, 2 lower end of screw rod are equipped with ailhead 3, between the head of a nail 1 and screw rod 2 also
Equipped with the first gasket 5, the lower end of first gasket 5 is connected with damping spring 4, and the screw rod 2 includes first body of rod 21 and the
Bipole body 22, second body of rod 22 are located at the outer end of first body of rod 21, and first body of rod 21 and second body of rod 22 are integrated
Formula structure, second body of rod, 22 lateral surface are equipped with screw thread 220, and the damping spring 4 is located at the outside of first body of rod 21, institute
The lateral surface for stating damping spring 4 is equipped with the second gasket 40, and second gasket 40 is cirque structure, second gasket 40
Bottom end be located at the junction of first body of rod 21 and second body of rod 22, the tapered structure of the ailhead 3.
Utility model works process:
A kind of self threading pin of damping of the utility model is inserted into 1 top of the head of a nail during the work time, using corresponding screw gun,
It inserts screws into material, will be fixed to each other between material；The first gasket 5 is equipped between the head of a nail 1 and screw rod 2, the first gasket 5
Lower end is connected with damping spring 4, and when being screwed into screw, the second gasket 40 of the bottom of damping spring 4 is in contact with material face, makes
Screw is more firm when being screwed into, and plays the role of weakening the shaking and vibration generated when being screwed into.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
