The utility model discloses a with the elastic ring setting in the auxiliary tank to cooperation adjusting bolt can die the further lock of nut after making bolt group screw up, has prevented the not hard up of bolt group.
Description
[technical field]
This utility model is related to the technical field of securing member, the particularly technical field of bolt group.
[background technology]
Bolt group is a kind of conventional securing member, and it is typically made up of screw bolt and nut, can be applied in many occasions.
If the occasion that bolt group uses can often shake, bolt group is easy to occur to loosen, and influences whether fastening effect.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, and proposition is a kind of to be difficult loosening bolt group, energy
Bolt group is enough made to be not susceptible to loosen.
For achieving the above object, the utility model proposes a kind of be difficult loosening bolt group, including screw rod, the first fixation
Head, the second fixing head, nut, elastic ring, regulating bolt, described screw rod one end is fixed with the first fixing head, and the first fixing head is another
One end is fixed with the second fixing head, and described first fixing head cross section is square, and the second fixing head cross section is rectangle, described
Nut is screwed with screw rod, the close first fixing rostral of nut is fixed with an anti-loosing slice, and anti-loosing slice is provided with self-locking burr, described
Nut inner wall is provided with a ring-type auxiliary tank, is provided with an elastic ring in auxiliary tank, and the bottom land of auxiliary tank is provided with some auxiliary spiral shells
Pit, additional threaded bores run through the side wall of nut, and additional threaded bores are screwed with regulating bolt.
Preferably, the internal diameter of described elastic ring is more than the internal diameter of nut, the length of regulating bolt is more than additional threaded bores
Length.
Preferably, described auxiliary tank is located at the middle part of nut, nut is hex nut, and each side of nut all has
One additional threaded bores.
The beneficial effects of the utility model: this utility model is by being arranged on elastic ring in auxiliary tank, and coordinates regulation
Bolt so that bolt group tighten after can will be further locked for nut it is therefore prevented that bolt group loosen；The setting of self-locking burr can
With effectively that nut is locked, prevent nut from occurring to loosen；The setting of the first fixing head and the second fixing head makes bolt group exist
Unloading process can be able to be completed using common spanner, and is difficult to skid.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[brief description]
Fig. 1 is a kind of front view being difficult loosening bolt group of this utility model.
In figure: 1- screw rod, 2- nut, 11- first fixing head, 12- second fixing head, 21- anti-loosing slice, 22- self-locking burr,
25- auxiliary tank, 26- elastic ring, 27- additional threaded bores, 28- regulating bolt.
[specific embodiment]
Refering to Fig. 1, this utility model is a kind of to be difficult loosening bolt group, solid including screw rod 1, the first fixing head 11, second
Fixed 12, nut 2, elastic ring 26, regulating bolt 28, described screw rod 1 one end is fixed with the first fixing head 11, the first fixing head 11
The other end is fixed with the second fixing head 12, and described first fixing head 11 cross section is square, and the second fixing head 12 cross section is in length
Square, described screw rod 1 is screwed with nut 2, close first fixing head 11 side of nut 2 is fixed with an anti-loosing slice 21, anti-loosing slice 21
It is provided with self-locking burr 22, described nut 2 inwall is provided with a ring-type auxiliary tank 25, is provided with an elastic ring in auxiliary tank 25
26, the bottom land of auxiliary tank 25 is provided with some additional threaded bores 27, and additional threaded bores 27 run through the side wall of nut 2, additional threaded bores
It is screwed with regulating bolt 28, the internal diameter of described elastic ring 26 is more than the internal diameter of nut 2, the length of regulating bolt 28 is more than auxiliary on 27
The length of screwed hole 27, described auxiliary tank 25 is located at the middle part of nut 2, and nut 2 is hex nut 2, on each side of nut 2
All there are additional threaded bores 27.
Utility model works process:
This utility model is a kind of to be difficult loosening bolt group in the course of the work, after bolt group is tightened, each is adjusted
Bolt 28 is tightened so that elastic ring 26 is in close contact with the external screw thread on screw rod 1, will be locked for nut 2 so that bolt group is difficult pine
Dynamic, when needing to unclamp bolt group, regulating bolt 28 is twisted and send so that elastic ring 26 is separated with the external screw thread of screw rod 1, nut
2 is no longer locked, and because the first fixing head 11 cross section is square, the second fixing head 12 cross section is rectangle, in bolt group
Unloading process in can use common wrench standing screw 1, easy to use and be difficult to skid.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
