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 on door, including the first lock body 3 for being installed in door body 1, installation In the chain 8 of the second lock body 4 and connection the first lock body and the second lock body on doorframe 2, wherein；

8 one end of chain is connected on the second lock body 2, is fixed in usually chain 8 and the second lock body 2, the other end of chain 8 is set There are sliding block 6, sliding block 6 to be slidably connected on the first lock body 3；

First lock body 3 is equipped with transverse slipway 5, and 5 bottom of slideway is equipped with the kerve 51 of broadening, and the width of sliding block 6 is less than bottom The width of slot 51, the top width of slideway 5 are less than the width of sliding block 6, such sliding block 6 both can in kerve 51 sliding but also Slideway 5 will not be slipped, is equipped with the socket 52 for inserting or pull out kerve 51 for sliding block 6 among slideway 5, the width of the socket 52 is more than The width of sliding block 6；Sliding block 6 is inserted into kerve 51 by socket 52 and is slided along kerve 51；Sliding block 6 i.e. on chain 8 passes through socket 52 are inserted into slideway 5, and are slided to the left or to the right in kerve 51；

5 both ends of slideway are equipped with spacer pin 7 by close end, and when sliding block 6 slides into 5 end of slideway along kerve 51, spacer pin 7 limits Sliding block 6 processed slides.Spacer pin 7 can be pulled manually, and common bolt may be selected, and bolt crosses sliding route of the slideway 5 by sliding block 6 Blocking can both limit the sliding of sliding block 6, and bolt is pulled when needing releasing to lock and gets through slideway 5, sliding block 6 is i.e. slidably.Due to It slides left and right both ends and is designed with spacer pin 7, so the sliding block 6 on chain 8 may be limited to the left and right company end of slideway 5, When locking, chain 8 is limited in different ends, crack between a door and its frame it is of different sizes.It can prevent from peeping when crack between a door and its frame is small or no gap Equal danger can be observed stranger outdoors or be engaged in the dialogue by crack between a door and its frame, transmit the behaviors such as article, but also can when crack between a door and its frame is big To prevent surprise attack behavior when stranger is a bad actor.Indoor occupant can select 6 glide direction of sliding block as needed.

In the above-mentioned technical solutions, chain 8 is fixed in the first fixing groove 41 of the second lock body 4, and the length of chain 8 is equal to First fixing groove 41 and air line distance of the slideway 5 far from end.When the sliding block 6 on chain 8 is fixed on slideway far from end, chain 8 In tensioned state, crack between a door and its frame smaller can be controlled.

Wherein, 8 end of chain by can tripper be locked in the first fixing groove 41 of the second lock body 4, dress can be unlocked It is set to mechanical lock or electronic lock.Anti-lock device in the present embodiment be mainly used for preventing indoor occupant because the reasons such as body without When method releases anti-lock device, it can be released by the portable key mating with mechanical lock or electronic lock of Migrant women It locks, hence into interior.It is mainly used in hotel, makes when guest accident occurs and needs to be forced into room indoors With.

More preferably, chain 8 is equipped with additional chain 9, and additional 9 one end of chain is connect with chain 8, and the other end is detachably connected In on the second lock body 4.Further increase safety can also be by attached when the connection of chain and the second lock body is destroyed Chain blocking door is added to be opened.

More preferably, the second lock body 4 is equipped with additional slideway 10, adds chain 9 and is equipped with additional sliding block 11, the additional chain Item 9 is slidably connected with the second lock body 4 by additional sliding block 11 and additional slideway 10, and additional slideway 10 is vertically arranged, and adds slideway 10 bottom end is equipped with the additional socket that additional sliding block 11 inserts or pull out additional slideway.Additional installation of slide track is in the first fixing groove 41 Lower part, when chain 8 and the connection of the second lock body 4 are destroyed, door is opened, but additional chain 9 under the effect of external force with 10 upward sliding of additional slideway.The additional chain 9 can choose whether to use as needed.It is urgent at the time of most dangerous It uses, can usually not use.

More preferably, the second lock body 4 is equipped with that Open Side Down and inclines the first lower fixing groove 41, and the chain is inserted into the first fixation Slot 41 and by can tripper lock.When open can tripper when, the end of chain 8 is under gravity automatically from the It is slid in one fixing groove 41.

In conclusion chain one end of the anti-lock device of the utility model is fixed on the second lock body, the other end can be It can be fixed by the spacer pin of setting when horizontally slipping in the transverse slipway on one lock body, and sliding into two ends, this It just prevents criminal by being locked outdoors using magnet movement sliding block and releasing, and is may be selected as needed by chain Sliding block is fixed on left end or right end, controls the size of crack between a door and its frame successively, is equipped with sliding block socket among slideway, certainly convenient for indoor occupant Unlock.

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.
