Description

Rotary self-lock pull head

Technical field

The present invention relates to a kind of slide fastener, refer to the zipper head of a kind of rotary self-locking and unblock especially.

Background technology

At present, self-locking zipper head is widely used to be made up of slider of zipper fastener body, a horse hook, a cap and a pulling-on piece.Chinese patent literature can be consulted in invention disclosed patent on December 10th, 2008 No. CN201160563 " a kind of slider of zipper fastener " (patent No.: CN200720058045.X).The pull head of this patent is Split type structure, combines with the nut upper and lower pull head that is tightened.Though this pull head can prevent others' opening slide fastener easily, just can not realize auto-lock function, use very inconvenience.There is slide fastener that is antitheft and auto-lock function also have, but mostly adopt outlet structure, Chinese patent literature No. CN202425725Uth, Chinese invention patent " a kind of anti-theft zipper lock buckle device " (patent No.: CN201120483776.5) disclosed on 09 12nd, 2012 can be consulted, its external locker, with left-hand thread tongue, zipper head is directly buckled on locker, not disguised, security is not high.And at present disguised antitheft slider of zipper fastener also has, Chinese patent literature Chinese invention patent No. CN101843390A " a kind of anti-pickpocket zipper puller " (patent No.: CN200910106185.3) disclosed on 09 29th, 2010 can be consulted.This pull head uses a push button switch to realize unlocking by the monodirectional locking shell fragment that a draught line is built in pull head inside, and have concealed anti-theft feature, but its structure is quite complicated, adopts the draught line of rapid wear, security protection is unstable.

Summary of the invention

For prior art Problems existing, the invention provides the simple rotary self-lock pull head of a kind of structure.This pull head can not by the impact of external force, and not fixing rotation is to realize self-locking and unblock, can be used in and be in for a long time on self-locking or the long-term dress ornament without lock, case and bag and tent, possess certain anti-theft feature simultaneously.

For achieving the above object, technical solution of the present invention is:

Rotary self-lock pull head, this pull head comprises a pull head body, a cap and a horse hook; Horse hook is resisted against in cap, and by being sheathed on its outer spring, knee-action in the perforate that pull head body is provided with; Cap rotates and is fixed on pull head body.

Further, pull head body is convexly equipped with threaded post, the cap threaded post that is spirally connected is fixed on pull head body.

Further, the die that the threaded post being spirally connected upper cap is deviate from its top formation restriction cap.

Further, also comprise one and be a tight fit in fixture in threaded post, this fixture locking cap is in threaded post.

Further, the pull head body by pulling cap to come described in action.

Pull head of the present invention is a kind of Novel self-lock pull head using screw thread rotation to realize self-locking and unblock.It uses screw thread operation principle, and make its spinning movement up or down by rotating cap, the upright horse hook that elasticity is arranged in cap moves up and down, realizes unlocking and self-locking.Cap is wider than the cap of prior art thicker, being suitable for hand pulling, can using as the function of pulling-on piece, reduce the combiner of pull head.The present invention adopts fixture to make cap not deviate from pull head body easily, the locking of not removing fixture to realize the self-locking of pull head and unblock, can be used in and be in for a long time on self-locking or the long-term dress ornament without lock, case and bag and tent, possess certain anti-theft feature simultaneously.

Detailed description of the invention

Now in conjunction with the accompanying drawings and embodiments the present invention is described.

Rotary self-lock pull head as shown in figs. 1-7, this pull head comprises pull head body 1, cap 2 and hook 3 of always pulling up a horse.Compared with prior art, cap 2 of the present invention is wider thicker, be suitable for hand hold after, pull head body by pulling cap 2 to come described in action, cap 2 can use as the function of pulling-on piece, decreases the building block of pull head.

Cap 2 of the present invention is built-in with a spring 4 and upright horse hook 3, described spring 4 is sheathed on outside upright horse hook 3,3 one, upright horse hook is resisted against cap 2, other end is by being sheathed on its outer spring 4, knee-action in the perforate 11 that pull head body 1 is provided with, makes pull head body 1 slide on slide fastener, stops.

Pull head body 1 of the present invention is convexly equipped with threaded post 12, and cap 2 of the present invention is secured on pull head body 1 by being screwed onto this threaded post 12.

During assembling, first spring 4 is positioned in the perforate 11 of pull head body 1; Then spring 4 put into by upright horse hook 2, then rotates cap 2 in the threaded post 12 of pull head body 1, and thread-rolling screw post 12 upper end makes cap 2 can not screw out pull head body 1, realizes the assembling of this self-locked draught part.

In order to make cap 2 not deviate from pull head body 1 easily, the present invention locks the fixed form of cap 2 on pull head body 1 to be had:

One, be configured with one and be a tight fit in fixture in threaded post 12, this fixture locking cap 2, in threaded post 12, makes cap 2 not deviate from pull head body 1 easily.

Embodiment one, fixture is as Figure 1-3 a bolt 5, and it is directly screwed onto in threaded post 12 through the through hole on cap 2.The bolt head step surface withheld on cap 2 through hole of abduction makes rotation cap not screw out, to lock cap 2 on pull head body 1.

Embodiment two, as shown in Figure 7, described fixture also can be a rivet 5, and it is directly rabbeted in threaded post 12 through the through hole on cap 2.The manufactured head step surface withheld on cap 2 through hole of abduction makes rotation cap not screw out, to lock cap 2 on pull head body 1.

Two, the mode adopting threaded post directly to fix:

Embodiment three, as Figure 4-Figure 6, the present invention also can on being spirally connected the top of the threaded post 12 of cap 2, directly form the die 121 that restriction cap 2 is deviate from.The manufactured head step surface withheld on cap 2 through hole of abduction makes rotation cap can not screw out to lock cap 2 on pull head body 1.

Because spring 4 is extruded by upright horse hook 3 active force existed all the time upwards, in conjunction with screw thread operation principle, rotation cap 2 rotates up or down and upright horse hook 3 can be made to move up and down, realizes unlocking and self-locking.

Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
