Specific implementation mode

To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings and have Body embodiment is described in further detail the utility model.

As shown in Figs 1-4, a kind of anti-lock device, including the first lock body 3 for being installed in door body 1, are installed on doorframe 2 The second lock body 4 and connect the chain 5 of the first lock body 3 and the second lock body 4,5 one end of the chain is connected on the second lock body 4, The other end of chain is equipped with sliding block, and sliding block is slidably connected in the slideway 8 being arranged on the first lock body 3, wherein：

Slideway 8 is horizontally placed on the first lock body 3, and the one end of slideway 8 far from doorframe 2 is equipped with the cannelure of vertical slideway 8 7, cannelure 7 forms the insert port of sliding block with 8 end of slideway；

Operation principle：When needing to be locked on the door, first the insertion end on the sliding block on chain is inserted by insert port Enter in slideway, then slides into one end far from insert port, the wherein transverse bar of right-angled intersection and longitudinal rod structure along slideway level At insertion end slided in inside groove, connecting shaft is slided in outer groove, and baffle is placed on the outside of outer groove, is solved when to anti-lock device It needs to be slid into sliding block at insert port with hand when lock, longitudinal rod is made to be directed at cannelure, can be extracted from inserting into the mouth, when outdoors Offender when wanting to open anti-lock device with the device of magnet class, be difficult that longitudinal rod is made to be aligned with cannelure first, Er Qieyi Denier withdraws magnet, and sliding block can block in slide-in hollow receiver space in slot direction along longitudinal direction.So wanting several from anti-lock device is opened outdoors It is impossible.

In the present embodiment, connecting shaft 61 is stripe board, and the length direction of stripe board and transverse bar are in 45 degree of angles, bar shaped The thickness of plate is less than the width of outer groove, and the length of stripe board is more than the width of outer groove.When along slideway sliding slider, need item The connecting shaft of shape plate rotates 45 degree and can be slided along outer groove, that is, when wanting to unlock anti-lock device, is also required to before extracting insertion end 45 degree of rotation can make longitudinal rod be directed at cannelure, further increase unlock difficulty, improve safety.

In the above-mentioned technical solutions, 5 end of chain by can tripper be locked in the fixing groove of the second lock body 4, institute State can tripper be mechanical lock or electronic lock.It, can be with when personnel's something unexpected happened can not unlock anti-lock device within doors By can tripper locked to release.

In the above-mentioned technical solutions, the second lock body 4 is equipped with that Open Side Down and inclines lower fixing groove 41, and chain 5 is inserted into fixation Slot 41 and by can tripper lock.Fixing groove Open Side Down tilt, open can tripper when, chain ends are in gravity Unlock is automatically fallen off under effect, convenient for unlock.

In the above-mentioned technical solutions, 5 middle part of chain is equipped with hook 10, and the doorframe 2 is equipped with and links up with matched extension Part 9.When an emergency happens, it can be matched with pendant by linking up with, so that anti-lock device is continuing with, and can reduce The size of crack between a door and its frame.Such as can tripper damage in the case of, when can not lock the one end that chain is connect with the second lock body, Chain can be made to continue to keep locking state by linking up with pendant.

In conclusion the anti-lock device of the utility model, the sliding block insertion end on chain is cross type, with slideway On the insert port cooperation of right-angled intersection be likely to extract, and the lower end of cannelure is equipped with hollow accommodation space, and sliding block is logical It crosses unlawful means to want to be easy to fall into the accommodation space and block when opening, considerably increase from wanting to beat by unlawful means outdoors The difficulty for opening anti-lock device improves the security performance of anti-lock device.

The explanation of above example is merely used to help understand the core concept of the utility model；Meanwhile for this field Those skilled in the art, according to the thought of the utility model, there will be changes in the specific implementation manner and application range, comprehensive Upper described, the content of the present specification should not be construed as a limitation of the present invention.
