The utility model discloses a dual -protection uses safelyr, and the head inserted position of whole bolt is provided with a terminal surface in addition, so the bolt can observe the circumstances about putting in place that has or not after inserting, and the change can be dismantled to the bolt in addition, practices thrift the cost.

Description

A kind of modified form window theft-proof lock

Technical field

The utility model is related to a kind of modified form window theft-proof lock.

Background technology

Pin lock is conventional window locks, and existing latch is when in use, general only one to protect again, that is, after inserting i.e. Can, but due to after latch insertion it is not clear whether insertion in place, therefore many times, latch has only inserted half, needs carefulness People can see whether in place from bottom watcher.And existing latch typically only has one-time positioning, anti-theft effect is universal It is not high.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of double protection, safer, and clearly can see Whether modified form window theft-proof in place is locked to examine latch.

The utility model is achieved through the following technical solutions：A kind of modified form window theft-proof lock, including latch with And latch fixture, just to snibbing position one pin hole of setting, latch is just arranged latch fixture to pin hole, latch bottom One side has an end face, forms a turning point between the end face and upper end latch, rear in latch insertion pin hole to transfer Portion bottom surface and latch fixture top contact, arrange lockhole on latch end face, latch fixture one side arranges lock, lockhole with Lock is arranged at the same face.

As preferred technical scheme, threaded connection section at the top of latch, is provided with, latch is threaded connection section connection The fixed body of upper end.

Used as preferred technical scheme, the lockhole is more than one longitudinally disposed blind hole, and lock adopts more than one For buckling into the stuck point in lockhole, stuck point through latch fixture side wall to pin hole, the outside of stuck point arranges one Fixed cover, connects a spring between fixed cover and salient point outboard end.

Used as preferred technical scheme, the inner side end of stuck point is provided with an arc surface, and the arc surface is arranged at upper end Face, is just arranged to latch.

Used as preferred technical scheme, the bottom of latch is arc convex surface, and the upper end open end of pin hole is in bell mouth shape.

The beneficial effects of the utility model are：The utility model adopts double protection, using safer, and entirely inserts The head insertion position of pin is provided with an end face, therefore i.e. observable whether there is situation in place, and latch after latch insertion It is detachable, it is cost-effective.

Description of the drawings

In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.

Fig. 1 is overall structure diagram of the present utility model.

Specific embodiment

All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive Feature and/or step beyond, can combine by any way.

This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically is chatted State, can be replaced by other equivalent or alternative features with similar purpose.I.e., unless specifically stated otherwise, each feature It is an example in a series of equivalent or similar characteristics.

As shown in figure 1, including latch 11 and latch fixture 8, latch fixture 8 just arranges one to snibbing position and inserts Pin-and-hole 9, latch 11 are just arranged to pin hole 9, and 11 bottom side face of latch has an end face 12, the end face and upper end latch it Between form a turning point 3, in latch insertion pin hole after turning point bottom surface and latch fixture top contact, on latch end face Lockhole 7 is set, and latch fixture one side arranges lock, and lockhole is arranged at the same face with lock.

Threaded connection section 5 is provided with the top of latch, and latch is threaded connection the fixed body 4 that section connects upper end, passes through The lower latch of screw thread dismounting is replaceable new latch, need not change total, prevent later stage latch from getting rusty using inflexible Situation.

In the present embodiment, lockhole 7 be more than one longitudinally disposed blind hole, latch using it is more than one for buckle in Stuck point 6 in lockhole, stuck point 6 pass through the side wall of latch fixture to pin hole, and the outside of stuck point arranges a fixation cover 1, Gu Connect a spring 2 between fixed cover and salient point outboard end.

When latch is inserted, stuck point is pushed out under the action of the spring, and when stuck point is just to lockhole, stuck point buckles into lockhole, complete Into locking, when needing to pull out latch, as long as outside fixed cover is pulled out, you can stuck point is pulled out lockhole, simple side Just.

In the present embodiment, the inner side end of stuck point is provided with an arc surface, and the arc surface is arranged at upper surface, just to inserting Pin is arranged；The bottom of latch is arc convex surface, and the upper end open end of pin hole is in bell mouth shape.

Due to being provided with turning point, as long as therefore latch arrive position see turning point either with or without contact lower end latch fix Part, solves latch and inserts situation not in place.

The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model. Therefore, the protection domain that protection domain of the present utility model should be limited by claims is defined.
