The utility model has the advantage of reasonable structure, its installation atress more strengthens, whole exploding can not appear and open the phenomenon, job stabilization in addition, convenient operation, long service life.

Description

Connection fastener

Technical field

The utility model relates to connection fastener, specifically a kind of connection fastener for connecting between aluminium alloy frame.

Background technology

With the needs of market development, the connection between aluminium alloy frame no longer adopts screw fashion, but majority is adopted Clamping, elastic connection, connect etc. mode, because this kind of connection makes installation more flexible without the need for the reserved screwed hole on aluminium, and And there is no the phenomenon of damaged screw when dismounting, but traditional connection fastener when mounted stress cross conference integrally pop or Because of positioning element of the afterbody without fixing tooth etc, when stress is big, latch hook can open toward left and right, so as to squeeze lock housing, these shortcomings Installing for aluminium alloy frame makes troubles.

Utility model content

The purpose of this utility model is to provide connection fastener, and its stress is excessive to be entered also will not integrally pop, and inside the shell Projection has latch hook limiting tooth, and shell ejection, and long service life will not be squeezed in latch hook stress, easy for installation.

Technical solution of the present utility model is the cap in shell, and latch hook, cam on the basis of spring, is characterized in Described latch hook, spring, cam is from top to bottom sequentially arranged inside the shell, and the rear of latch hook is provided with through hole, and front end is three Stretch bar, the through hole of latch hook rear to pack into the wheel of cam, that stretching, extension bar interlude in the middle of latch hook front end is bent downwardly Projection, latch hook tail end middle is provided with bayonet socket, stretch in the middle of shell Inner Front End and latch hook front end the corresponding position of bar to Internal projection has jacking block, and jacking block can stretch bar when latch hook is moved forward in the middle of jack-up latch hook, in inside the shell tail end and latch hook tail end Inwardly protruding on the corresponding position of bayonet socket to have fixture block, fixture block can be inserted in the bayonet socket of latch hook tail end.

Operation principle of the present utility model is that have jacking block because shell Inner Front End and tail end are convex respectively when aluminium alloy frame connects And fixture block, force latch hook to move forward when cam rotates, bar is stretched in the middle of latch hook tight so as to sting by jack-up off center line In the mounting bar hole of aluminium alloy frame, when latch hook is by cam thrust force because the bayonet socket of latch hook afterbody and the fixture block of inside the shell sting tightly, from And make the displacement of latch hook more steady, be not in the phenomenon of shell over extruding.

The utility model has the advantages that rational in infrastructure, its installation stress is more increased, and is not in the overall phenomenon that pops, and And working stability, easy to operate, long service life.

Specific embodiment

According to Fig. 1, Fig. 2, Fig. 3, the utility model is on shell 1, cap 2, latch hook 5, cam 4, the basis of spring 3 On, it is characterized in that described latch hook 5, spring 3, cam 4 are from top to bottom sequentially arranged in shell 1, the rear of latch hook 5 is provided with Through hole, front end is that three stretching, extension bars, the through holes of the rear of latch hook 5 are packed into the wheel of cam 4, and that in the middle of the front end of latch hook 5 is stretched Exhibition bar interlude is bent downwardly projection, and the tail end middle of latch hook 5 is provided with bayonet socket, in the middle of the Inner Front End of shell 1 and the front end of latch hook 5 The corresponding position of stretching, extension bar is inwardly protruding jacking block 6, and jacking block 6 can stretch bar when latch hook 5 is moved forward in the middle of jack-up latch hook, Inwardly protruding on the tail end position corresponding with the tail end bayonet socket of latch hook 5 in the shell 1 to have fixture block 7, fixture block 7 can be inserted into latch hook 5 Bayonet socket in.

Claims

1. connection fastener, it includes shell, cap, latch hook, cam, spring, it is characterized in that described latch hook, spring, cam by Inside the shell is up to sequentially arranged at down, and the rear of latch hook is provided with through hole, and front end is three and stretches bar, the through hole set of latch hook rear Enter with the wheel of cam, that stretching, extension bar interlude in the middle of latch hook front end is bent downwardly projection, and latch hook tail end middle is arranged There is bayonet socket, the corresponding position of stretching, extension bar is inwardly protruding in the middle of shell Inner Front End and latch hook front end jacking block, and jacking block can be in lock Bar is stretched when hook is moved forward in the middle of jack-up latch hook, to convex on the inside the shell tail end position corresponding with latch hook tail end bayonet socket Rising has fixture block, and fixture block can be inserted in the bayonet socket of latch hook tail end.
