Abstract
The utility model discloses a snap button type zipper. The snap button type zipper adopts the structure that an arc-shaped spring is arranged on the inner side of a slot of the zipper at the position close to the socket of the slot; the inner diameter of the socket of the slot is smaller than that of the position where the arc-shaped spring is positioned in the slot; the outer diameter of an inwardly depressed arc-shaped waist part of a bolt matched with the slot is smaller than that of the head of the bolt; and the cross sections of both the slot and the bolt adopt annular or elliptical constitution. According to the utility model, the bolt is inserted into the slot for effective locking, which not only facilitates proper dressing of clothes and normal use of the suitcases, but also avoids property loss.
Description
Technical field
The utility model relates to a kind of slide fastener, especially a kind of press button formula slide fastener that strengthens the interlock dynamics.
Background technology
The common defects that exists of the slide fastener of generally selling in the market, be exactly behind the zip up sprocket throw off easily, main cause is that latch inserts in the slot and is not effectively locked.Because sprocket is thrown off, both influenced the normal use of the smartly dressed and case and bag of clothing, also can cause property to lose.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of and strengthen the interlock dynamics, effectively lock the slide fastener of sprocket.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the press button formula slide fastener of slide fastener and chain lock, the slot of slide fastener is provided with " bow " font spring near its socket inboard.
The socket internal diameter of described slot is less than the internal diameter of " bow " font spring present position in the slot.
Described and the curved waist external diameter that caves inward of the matching used latch of slot are less than the plug external diameter of latch.
Rounded or the elliptical configuration in the cross section of described slot and latch.
The utility model has the advantages that: because the slot of slide fastener is provided with " bow " font spring near its socket inboard, the socket internal diameter that is equipped with slot less than the internal diameter of " bow " font spring present position in the slot and with the plug external diameter of the curved waist external diameter that caves inward of the matching used latch of slot less than latch, after latch inserts, slot tightly withstands the curved waist that caves inward of latch near " bow " font spring of its socket inboard, after the slide fastener closure, latch is difficult to throw off voluntarily.Under the pulling force of chain lock, the plug of latch breaks away from " bow " font spring, can open slide fastener easily.This slide fastener interlock dynamics strengthens, latch is effectively locked, and has solved the problem that gets loose of zipper sprocket preferably.Rounded or the elliptical configuration in the cross section of slot and latch then helps latch and passes in and out in slot along sliding.
Description of drawings
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the cross-sectional view that reaches " bow " font spring concrete structure according to the slot that utility model proposes.
Fig. 2 is the vertical section figure according to two mutual interlocks of sprocket of utility model proposition.
(1) is slot among the figure, and (2) are the socket of slot, and (3) are spring, and (4) are latch, and (5) are the waist of latch, and (6) are the plug of latch.
The specific embodiment
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
The press button formula slide fastener that comprises slide fastener and chain lock, the slot of slide fastener (1) is provided with " bow " font spring (3) near its socket (2) inboard; Socket (2) internal diameter of slot (1) is less than the internal diameter of " bow " font spring (3) present position in the slot (1); With plug (6) external diameter of the curved waist that caves inward of the matching used latch of slot (1) (4) (5) external diameter less than latch (4); The rounded structure in cross section of slot (1) and latch (4).
After this press button formula slide fastener was pulled on by chain lock, the tightly locking mutually of two row's sprockets seldom the situation that slide fastener gets loose can occur.
Claims (2)
1. press button formula slide fastener comprises slide fastener and chain lock, and the slot (1) of zipper sprocket that is characterised in that of the present utility model is provided with " bow " font spring (3) near its socket (2) inboard;
Socket (2) internal diameter of described slot (1) is less than the internal diameter of " bow " font spring (3) present position in the slot (1);
Described and the curved waist that caves inward of the matching used latch of slot (1) (4) (5) external diameter are less than plug (6) external diameter of latch (4).
