Description

Bolt

Technical field

The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of bolt.

Background technique

Bolt, by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, needs and nut screw connection, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.

And when bolt be connected to be given a shock for a long time time, there will be loosening between nuts and bolt, thus cause nut and bolt falling, the nut that prevents that the screw rod that some bolt adopts in the market inserts latch and so near the position of bottom comes off, but this just causes latch easily to be lost, and each installation all needs first to be taken off by latch, extremely bothers.And be designed to plane due to one end of bolt head, therefore some rainwater are easily piled up at bolt head place, thus cause bolt head to get rusty.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bolt preventing nut from dropping.

For achieving the above object, the utility model provides following technological scheme: a kind of bolt, comprise bolt head and screw rod, the top of described screw rod is fixedly connected with bolt head, the side of described screw rod is provided with chute near screw rod bottom, the slide block of thrust spring and slip is provided with in described chute, one end of one end chute relative to slide block of described thrust spring is fixedly connected with, the other end is fixedly connected with the bottom of chute, one end of described slide block protrudes from chute, described chute can accommodate slide block, the seamed edge that described slide block protrudes from the relative screw rod bottom, one end of chute is bevel edge.

Preferably, the bottom of described screw rod is provided with the circular groove communicated with chute, the fixture block of slip is provided with in described circular groove, the sidewall of described fixture block is provided with limiting stopper, be provided with in described screw rod and corresponding with limiting stopper enter block groove, the first annular groove, the second annular groove that coaxially arrange with circular groove is provided with in described screw rod, the first described annular groove, the second annular groove all with enter block groove and communicate, the first described annular groove bottom the second annular groove and screw rod between, described slide block is provided with the draw-in groove corresponding with fixture block.

Preferably, the length of described fixture block is greater than the degree of depth of circular groove.

Preferably, described bolt head is towards laterally inclined by the centre of bolt head back to one end of screw rod.

Compared with prior art, the beneficial effects of the utility model are: when nut dress is slowly screwed into one end of the relative bolt head of screw rod, nut can contact with bevel edge gradually, and slide block can be pushed away in chute along with continuing to turn nut, until slide block is whole be positioned at chute, at this moment thrust spring is in compressive state, after nut and slide block separate, slide block ejects by thrust spring, and when nut loosening time, owing to being plane contact between nut and slide block, therefore slide block cannot push in chute by nut, thus reach the function preventing nut from dropping, in time will backing out nut, push in chute by whole for slide block, nut can be taken out.

Accompanying drawing explanation

Fig. 1 is the slide block of the utility model screw embodiment structural drawing when protruding from chute;

Fig. 2 is the structural drawing that the slide block of the utility model screw embodiment is positioned at chute;

Fig. 3 is the partial enlarged drawing of A in Fig. 2;

Fig. 4 is the structural drawing of the utility model screw embodiment.

Reference character: 1, bolt head; 2, screw rod; 21, circular groove; 22, the second annular groove; 23, the first annular groove; 24, chute; 25, block groove is entered; 3, slide block; 31, bevel edge; 32, draw-in groove; 4, limiting stopper; 5, fixture block; 6, thrust spring.

Embodiment

Referring to figs. 1 through Fig. 4, the utility model screw embodiment is described further.

A kind of bolt, comprise bolt head 1 and screw rod 2, the top of described screw rod 2 is fixedly connected with bolt head 1, the side of described screw rod 2 is provided with chute 24 near screw rod 2 bottom, the slide block 3 being provided with thrust spring 6 in described chute 24 and sliding, one end of one end chute 24 relative to slide block 3 of described thrust spring 6 is fixedly connected with, the other end is fixedly connected with the bottom of chute 24, one end of described slide block 3 protrudes from chute 24, described chute 24 can accommodate slide block 3, the seamed edge that described slide block 3 protrudes from relative screw rod 2 bottom, one end of chute 24 is bevel edge 31.

When one end nut dress being slowly screwed into the relative bolt head 1 of screw rod 2, nut can contact with bevel edge 31 gradually, and slide block 3 can be pushed away in chute 24 along with continuing to turn nut, until slide block 3 is whole be positioned at chute 24, at this moment thrust spring 6 is in compressive state, after nut and slide block 3 separate, slide block 3 ejects by thrust spring 6, and when nut loosening time, owing to being plane contact between nut and slide block 3, therefore slide block 3 cannot push in chute 24 by nut, thus reach the function preventing nut from dropping, in time will backing out nut, push in chute 24 by whole for slide block 3, nut can be taken out.

The bottom of described screw rod 2 is provided with the circular groove 21 communicated with chute 24, the fixture block 5 of slip is provided with in described circular groove 21, the sidewall of described fixture block 5 is provided with limiting stopper 4, be provided with in described screw rod 2 and corresponding with limiting stopper 4 enter block groove 25, coaxial the first annular groove 23 arranged with circular groove 21 is provided with in described screw rod 2, second annular groove 22, the first described annular groove 23, second annular groove 22 all with enter block groove 25 and communicate, the first described annular groove 23 bottom the second annular groove 22 and screw rod 2 between, described slide block 3 is provided with the draw-in groove 32 corresponding with fixture block 5, in time will being screwed into nut, limiting stopper 4 is made to be positioned at the first annular groove 23, fixture block 5 departs from draw-in groove 32, when nut contact chamfering time, slide block 3 can push in chute 24 by nut, in time will pulling down nut, rotate fixture block 5, limiting stopper 4 is made to be positioned at into block groove 25 place, then make that slide block 3 is whole is positioned at chute 24, then fixture block 5 is promoted, fixture block 5 one end is made to be positioned at draw-in groove 32, now limiting stopper 4 is just in time positioned at the second annular groove 22 place, rotate fixture block 5, fixture block 5 is made to be positioned at restraining groove, can make to prevent fixture block 5 from departing from draw-in groove 32, at this moment just nut can be taken off very easily.

The length of fixture block 5 is greater than the degree of depth of circular groove 21, prevents that fixture block 5 is whole to be positioned at circular groove 21 and to cause the fixture block 5 that cannot well rotate or slide.

Bolt head 1 back to one end of screw rod 2 be by the centre of bolt head towards laterally inclined, prevent some rainwater from piling up at bolt head 1 place.
