The utility model discloses a kind of box fastener, particularly relate to a kind of spring self-locking box buckle, comprise box fastener main body (3), Slip Hook (4), steady pin (5), buckle shaft (6), snap fit pin (7) and spring (8), described box fastener main body (3) is arranged on the lateral edges of case lid (1) by steady pin (5), described buckle shaft (6) is fixedly installed in box fastener main body (3), described Slip Hook (4) is installed on box fastener main body (3) by the cooperation of the bar shaped sliding eye on it and buckle shaft (6), the chien shih buckle shaft (6) of below and box fastener main body (3) that described spring (8) withstands on Slip Hook (4) has necessarily stroke distances upwards in described bar shaped sliding eye, described snap fit pin (7) is fixedly mounted on the first-class feature of lateral edges of casing (2).The distortion snap close that the utility model avoids latch part causes easily being opened by external force is improper, because folding of the present utility model there is no wearing and tearing to parts, permanently effectively can use, can not reduce performance.

Description

A kind of spring self-locking box buckle

Technical field

The utility model relates to a kind of box fastener, particularly relates to a kind of spring self-locking box buckle.

Background technology

Existing casing snap close and box fastener, generally all be made up of kinge-joint knot and clip two parts, its locking function mutually extrudes by kinge-joint knot and clip, enter catching groove after distortion to snap together, its folding is all pass through after locking place being out of shape by applying pressure and pulling force, the box fastener of this structure has individual shortcoming, namely its folding only needs applied pressure or pulling force enough can open, such as easily throw off voluntarily when colliding, and after Long-Time Service, snap close easily forms distortion fatigue thus does not reach locking effect, this all comparatively bothers in carrying and storing process.

Utility model content

The purpose of this utility model is to provide a kind of spring self-locking box buckle, solves existing casing snap close without auto-lock function, easily opens because of anon-normal constance forces such as collisions, the problem that after Long-Time Service, locking ability declines.

For solving the problem, technical solution adopted in the utility model is:

A kind of spring self-locking box buckle, comprise box fastener main body, Slip Hook, steady pin, buckle shaft, snap fit pin and spring, described box fastener main body is arranged on the lateral edges of case lid by steady pin, described buckle shaft is fixedly installed in box fastener main body, described Slip Hook is installed in box fastener main body by the cooperation of the bar shaped sliding eye on it and buckle shaft, described spring top has necessarily stroke distances upwards in the chien shih buckle shaft of the below of Slip Hook and box fastener main body in described bar shaped sliding eye, described snap fit pin is fixedly mounted on the lateral edges of casing, the crotch of described Slip Hook upwards fastening snap fit pin from below under the action of the spring, the hook that described buckle shaft stroke distances upwards in described bar shaped sliding eye is greater than described crotch is dark.

Further technical scheme is, described Slip Hook is provided with for the press section of receiving or finger presses downwards, and described box fastener main body is provided with and stretches into for hand or finger the pulling hole pressing described press section.

Further technical scheme is, is provided with the gathering sill slided up and down for described Slip Hook in described box fastener main body.

The beneficial effect adopting technique scheme to produce is: the utility model adopts high yellow self-locking manner, the distortion snap close avoiding latch part causes easily being opened by external force is improper, the mode of opening cannot not opened accurately, and wearing and tearing be there is no to parts due to folding of the present utility model, permanently effectively can use, glad energy can not be reduced.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Fig. 1, Fig. 2 and Fig. 3 shows an embodiment of a kind of spring self-locking box buckle of the utility model: a kind of spring self-locking box buckle, comprise box fastener main body 3, Slip Hook 4, steady pin 5, buckle shaft 6, snap fit pin 7 and spring 8, described box fastener main body 3 is arranged on by steady pin 5 on the lateral edges of case lid 1, described buckle shaft 6 is fixedly installed in box fastener main body 3, described Slip Hook 4 is installed in box fastener main body 3 by the cooperation of the bar shaped sliding eye on it and buckle shaft 6, described spring 8 withstands on the below of Slip Hook 4 and the chien shih buckle shaft 6 of box fastener main body 3 necessarily stroke distances upwards in described bar shaped sliding eye, described snap fit pin 7 is fixedly mounted on the lateral edges of casing 2, the crotch of described Slip Hook 4 upwards fastening snap fit pin 7 from below under the effect of spring 8, the hook that described buckle shaft 6 stroke distances upwards in described bar shaped sliding eye is greater than described crotch is dark.

As shown in Figure 3-Figure 5, when case lid 1 and casing 2 close, Slip Hook 4 in this spring self-locking box buckle under the effect of spring 8 upwardly, cause buckle shaft 6 in described bar shaped sliding eye, have necessarily stroke distances upwards, that is buckle shaft 6 is in the bottom of bar shaped sliding eye, buckle shaft 6 can stressed rear upward sliding or the stressed rear slide downward of Slip Hook 4, and the crotch simultaneously on Slip Hook 4 fastens the mutual locking that snap fit pin 7 realizes case lid 1 and casing 2.When needs open case lid 1 and casing 2, the power that Slip Hook 4 one is downward can be given, namely contrary with the elastic force of spring 8, Slip Hook 4 slide downward after being under pressure, buckle shaft 6 moves to the top of bar shaped sliding eye, and due to described buckle shaft 6 stroke distances upwards in described bar shaped sliding eye, to be greater than the hook of described crotch dark, then when buckle shaft 6 moves to the top of bar shaped sliding eye, crotch and snap fit pin 7 are thrown off mutually, now can open case lid 1 and casing 2.

According to a preferred embodiment of a kind of spring self-locking box buckle of the utility model, described Slip Hook 4 is provided with for the press section of receiving or finger presses downwards, described box fastener main body 3 is provided with and stretches into for hand or finger the pulling hole pressing described press section, this architectural feature person of being easy to use beats pressing Slip Hook 4, convenient and swift, and due to Slip Hook 4 be in box fastener main body 3, its press section is also press after needing hand or finger to stretch into, all not easily touch by foreign object projection and cause improper opening.

According to another preferred embodiment of a kind of spring self-locking box buckle of the utility model, be provided with the gathering sill slided up and down for described Slip Hook 4 in described box fastener main body 3, gathering sill can fix the movement locus of Slip Hook 4.

Although be described the utility model with reference to multiple explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the distortion carried out building block and/or layout and improving, to those skilled in the art, other purposes also will be obvious.
