Description

A kind of lock

Technical field

The utility model relates to a kind of lockset, specifically is that a kind of interior outside from door clamps the lock that remains one with two fan door-plates.

Background technology

In the every field of daily life, lockset all is the necessity that ensures property safety, and its safe coefficient is extremely important.The existing glass door generally is with common U-shaped lock, on the two fan glass doors handle is installed all, and the U-shaped lock passes from the handle on the two fan glass doors, is one with two fan glass door locks then.The safety of this lockset is too dependent on the quality of glass door handle, and existing glass door handle intensity is generally not high, suffers violence damage easily, and safety is relatively poor.

In the patent No. is " ZL03273641.X "; Name is called in the patent document of " a kind of glass door lock " and discloses a kind of lockset; It comprises and is held on two lock body and the snap closes split on the glass door respectively; Wherein, Above-mentioned lock body and snap close comprise the interior holder that is set in parallel in the glass door both sides and outer holder, are characterized in being respectively equipped with the arc dead bolt and can driving the driving mechanism that the arc dead bolt is made arcuate movement in the inside and outside holder of above-mentioned lock body, and being provided with of correspondence can supply lockhole that above-mentioned arc dead bolt penetrates and pass and chamber that can ccontaining arc dead bolt on the inside and outside holder of above-mentioned snap close.Though the security performance of this lockset increases, its ability of bearing violence damage is still not enough, because its clamping area to door-plate is less, and there is defective in the mode of installing and fixing, and under the situation that pushes hard the sliding door plate, lockset comes off easily.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that exists in the prior art; A kind of lock of simple and ingenious structure is provided; This lock can clamp two fan door-plates from the interior outside of door and remain one, is difficult to through violent means door-plate destroyed, and is safe.

The technical scheme that provides according to the utility model: a kind of lock; It is characterized in that: comprise inner splint and external splint; On the front surface of inner splint, be fixed with the locking bolt that can pass, on surface behind the external splint, offer the aperture that is used for the locking bolt insertion from the intermediate gap of two fan door-plates; On the said external splint lock body is installed, lock body have sealed with open two states, is connected with said locking bolt when lock body is sealed and fixes, be connected with said locking bolt disengaging when lock body is opened.

As the further improvement of the utility model, the front end of said locking bolt offers fixing hole, and said lock body has a telescopic locking bar; When lock body was sealed, locking bar stretched out and inserts the fixing hole of locking bolt front end; When lock body was opened, locking bar retraction also withdrawed from the fixing hole of locking bolt front end.

As the further improvement of the utility model, said locking bolt middle part is installed with a support bar that plays the rest effect, and the thickness of the length of locking bolt tail end greater than door-plate is arrived in support bar and locking bolt tie point position.

As the further improvement of the utility model, said locking bolt is flat sheet.

As the further improvement of the utility model, the edge at said inner splint and external splint two ends is coated with soft material.

The utility model compared with prior art, advantage is: simple and ingenious structure, can be from the interior outside of door two fan door-plates be clamped and remain one, be difficult to door-plate destroyed through violent means, safe.

The specific embodiment

Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.

As shown in the figure: said lock mainly is made up of inner splint 2 and external splint 5, on the front surface of inner splint 2, is fixed with the locking bolt 3 that can pass from the intermediate gap of two fan door-plates 1, on surface, external splint 5 back, offers to be used for the aperture 6 that locking bolt 3 inserts; On the said external splint 5 lock body 8 is installed, lock body 8 have sealed with open two states, is connected with said locking bolt 3 when lock body 8 is sealed and fixes, be connected with said locking bolt 3 disengagings when lock body 8 is opened.

Like Fig. 1 ~ shown in Figure 3, the front end of said locking bolt 3 offers fixing hole 9, and said lock body 8 has a telescopic locking bar 7; When lock body 8 was sealed, locking bar 7 stretched out and inserts the fixing hole 9 of locking bolt 3 front ends; When lock body 8 was opened, locking bar 7 retraction also withdrawed from the fixing hole 9 of locking bolt 3 front ends.

Like Fig. 1, shown in Figure 2, said locking bolt 3 middle parts are installed with a support bar 4 that plays the rest effect, and support bar 4 arrives the thickness of the length of locking bolt 3 tail ends greater than door-plate 1 with locking bolt 3 tie point positions.In concrete the application, at first inner splint 2 is buckled in wherein on the Yishanmen plate 1, support bar 4 can be supported on the handle of door-plate 1 and can not fall; Inner splint 2 need not hand steered; Load onto external splint 5 then, locking bolt 3 front ends are inserted in the lip-deep aperture 6 in external splint 5 backs, insert key then; Lock body 8 is sealed, thus from the interior outside of door 1 clamping of two fan door-plates is remained one.

In theory, the slit in the middle of the two fan door-plates 1 is narrow more, and this lockset can remain one with it more, and safety is also just high more, and correspondingly, said locking bolt 3 preferably should be set to flat sheet, so that the slit between the two fan door-plates 1 can be done is narrower.

In addition, the edge at said inner splint 2 and external splint 5 two ends is coated with soft material, so that the user grips and play the certain protection effect.
