Embodiment 1

[0027] Embodiment one, such as Figure 1-3 The shown fixing part is a bolt 5 , which passes through the through hole on the cap 2 and is directly screwed on the threaded post 12 . The outstretched bolt head buckles the step surface on the through hole of the cap 2 so that the rotating cap cannot be unscrewed, so as to lock the cap 2 on the slider body 1 .

Embodiment 2

[0028] Embodiment two, such as Figure 7 As shown, the fixing member can also be a rivet 5 , which passes through the through hole on the cap 2 and is directly embedded in the threaded post 12 . The outstretched rivet head buckles the step surface on the through hole of the cap 2 so that the rotating cap cannot be unscrewed, so as to lock the cap 2 on the slider body 1 .

[0029] 2. The method of direct fixing with threaded column:

Embodiment 3

[0030] Embodiment three, such as Figure 4-6 As shown, the present invention can also directly form a rivet head 121 that restricts the cap 2 from coming out on the top of the threaded column 12 that is screwed onto the cap 2 . The outstretched rivet head buckles the stepped surface on the through hole of the cap 2 so that the rotating cap cannot be unscrewed to lock the cap 2 on the slider body 1 .

[0031] Because the spring 4 is squeezed by the upright horse hook 3, there is always an upward force, combined with the working principle of the thread, the upward or downward rotation of the rotating cap 2 can make the upright horse hook 3 move up and down, realizing unlocking and self-locking.

Abstract

The invention discloses a rotary self-lock pull head, which comprises a pull head body, a cap and a hook; the hook resists into the cap and moves upward and downward in an opening arranged on the pull head body according to a spring sleeved outside the hook; and the cap is fixedly arranged on the pull head body in a rotation manner. The action of the pull head body is realized by pulling the cap. The pull head is a novel self-lock pull head via the rotation in a threading way to realize the self-lock and the unlocking. By the utilization of the principle of working in the threading way, according to the rotation of the cap, the pull head is enabled to move upward and downward in the rotation manner, an upright hook arranged in the cap in an elasticity way is enabled to move upward and downward, and the unlocking and the self-lock are realized. The cap can be used as a pull sheet, and the number of combining parts is reduced. According to the self-lock pull head, the self-lock and unlocking of the pull head can not be realized unless removing the locking of a fixing piece, thus the self-lock pull head can be applied in clothing, a case and a tent which are self-locked or without a lock in a long term, and the self-lock pull head is provided with a certain anti-theft function.

Description

technical field [0001] The invention relates to a zipper, in particular to a rotary self-locking and unlocking zipper slider. Background technique [0002] At present, the widely used self-locking zipper slider is composed of a zipper slider body, a horse hook, a cap and a pull piece. Can refer to Chinese patent document No. CN201160563 " a kind of slide fastener puller " (patent number: CN200720058045.X) of invention patent disclosed on December 10, 2008. The slider of this patent is a split structure, which is formed by tightening and fixing the upper and lower sliders with a nut. Although the slider can prevent others from easily opening the zipper, it cannot realize the self-locking function and is extremely inconvenient to use. There are also zippers with anti-theft and self-locking functions, but most of them adopt an external structure. You can refer to the Chinese invention patent No. CN202425725U "a kind of anti-theft zipper lock device" published on September 12,...
