Abstract
The utility model relates to a bolt, in particular to a one-way tightening bolt. The utility model has the technical scheme that the one-way tightening bolt comprises a screw and a nut, wherein a zigzag annular groove is arranged in an inner hole of the nut; and a reverse zigzag annular groove is arranged at the threaded part of the screw and is mutually matched with the zigzag annular groove in the inner hole of the nut. The one-way tightening bolt has the beneficial effects that the structure is simple, the tightening is convenient, and the bolt connection problems in the burglarproof, detaching resistant, replacement resistant and other fields can be effectively solved.
Description
Technical field:
The utility model relates to a kind of bolt, particularly a kind of unidirectional tighting a bolt.
Background technique:
Scyewed joint reach in daily life in the industrial and agricultural production use very general, mainly be applicable to several parts are linked together, or part is fixed on certain position, scyewed joint mainly is to realize by screw rod and nut, the common nut that requires usually commonly used can oppositely disassemble, but can not guarantee oppositely not get loose automatically, in order to solve the problem that gets loose automatically, people have invented some anti-loosing devices, for example adopt that two screw caps are tightened, compression spring compresses, locking fin etc.These loosen the device major part and can not guarantee to get loose anything but oppositely manpower dismounting.
Require nut can not get loose automatically and can not oppositely dismantle by manpower at some production and sphere of life, after promptly requiring disposable fastening nut, nut can not be dismantled, for example the screw thread on the Anti-theft door and window is fixedly connected, the set screw nut of registration number board etc., can only take the special tool(s) brute force to abolish if toll breakdown, therefore just need this special bolt.
Summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of unidirectional tighting a bolt is provided, and can effectively solve the bolt connectivity problem in fields such as antitheft, anti-dismounting, anti-replacing.
Its technological scheme is: comprise screw rod and nut, the endoporus of described nut is provided with the flexuose circular groove, screw flight partly is provided with reverse saw dentation circular groove, and the reverse saw dentation circular groove that described screw flight partly is provided with and the flexuose circular groove of nut inner hole mate mutually.
The beneficial effects of the utility model are: simple in structure, be convenient to tighten, and can effectively solve the bolt connectivity problem in fields such as antitheft, anti-dismounting, anti-replacing.
Description of drawings:
Accompanying drawing 1 is an a kind of embodiment's of the present utility model structural representation;
Accompanying drawing 2 is structural representations of another kind of embodiment of the present utility model;
Accompanying drawing 3 is enlarged views of the local M that cooperates with screw rod flexuose circular groove of nut;
Among the last figure: upper link A, lower link B, screw rod 1, nut 2, flexuose circular groove 3 and reverse saw dentation circular groove 4.
Embodiment:
In conjunction with the accompanying drawings 1-3, the utility model will be further described:
The utility model comprises screw rod 1 and nut 2, the endoporus of described nut 2 is provided with flexuose circular groove 3, the helical thread portion of screw rod 1 is provided with reverse saw dentation circular groove 4, the reverse saw dentation circular groove 4 that described screw rod 1 is provided with mates mutually with the reverse saw dentation circular groove 3 of nut 2 endoporus, specifically with reference to accompanying drawing 3.
When fastening nut 2, two reverse sawtooth can slip over smoothly by resiliently deformable, so that compress coupled, if dismounting nut 2, two reverse saw dentation circular grooves embed just mutually, can't relative movement, so just guaranteed that 2 on nut advances not move back, this reverse flexuose circular groove cooperates can make nut 2 relative screw rods 1 unidirectionally tighten, and can not return, and reaches this bolt and connects purpose locking, anti-dismounting.
As Fig. 1, if upper link A and lower link B thickness are limited, adopt general bolt form commonly used, coupled the bolt of packing into is with the clockwise fastening nut of spanner, because nut is opposite with the sawtooth direction of screw rod, nut will only advance not move back, in case be screwed into, will can not get loose automatically, with non-dismountable yet, therefore that will note installing is disposable, trial assembly repeatedly.
As Fig. 2, if there is a coupling thickness excessive, should adopt stud bolt, be screwed into double threaded screw earlier, with on another coupled screw rod of packing into, fastening again by nut.
Claims (1)
1. unidirectional tighting a bolt, comprise screw rod and nut, it is characterized in that: the endoporus of described nut is provided with the flexuose circular groove, screw flight partly is provided with reverse saw dentation circular groove, and the reverse saw dentation circular groove that described screw flight partly is provided with and the flexuose circular groove of nut inner hole mate mutually.
