Abstract
The invention relates to a latch lock and comprises a bolt that is disposed in a door body and can be inserted into the doorframe. The bolt is connected with a connecting rod mechanism (3) which can drive the bolt to move upwards and downwards. The invention further includes a poking rod (4) that can drive the connecting rod mechanism (2) to rotate. Since the linkage mechanism for the latch lock of the invention is concealed in the doorframe, the door body can be pushed open from the inside and can only be opened with a key from the outside, thus ensuring safety and facilitating usage; the latch lock of the invention is simple in structure, highly reliable, and easy to manufacture and spread for wide application, and uses return spring to enable the bolt to stick into a groove on the doorframe in order to lock the door body.
Description
Technical field
The present invention relates to the tripper in the sliding door, in the escape that more particularly are applied to use under the case of emergency of communal facilitys such as subway platform safety door, shield door.
Background technology
On the escape that the push rod lock of prior art is widely used in using under the case of emergency of public places such as subway, cinema, owing to need push rod lock preferably can open easily without key in inside, be convenient to personnel and withdraw, externally use key operatedly, prevent that unrelated person from entering.
Summary of the invention
The technical problem to be solved in the present invention is that the above-mentioned defective at prior art provides a kind of push rod lock.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of push rod lock, the push rod that comprises the inserted doorframe that is arranged on Men Tizhong, described push rod with can drive the linkage that described push rod moves up and down and link to each other, also comprise driving the dead man that described linkage rotates.
In push rod lock of the present invention, described push rod comprises the upper push-rod that inserts upper door frame respectively and inserts the lower push-rod of lower door frame, between described upper push-rod and the lower push-rod by can drive described upper push-rod and lower push-rod in opposite directions or the linkage of motion dorsad link to each other.
In push rod lock of the present invention, also be included in door opening state and be used for resetting-mechanism that described lower push-rod jack-up is not fallen.
In push rod lock of the present invention, described resetting-mechanism comprises the latch that is fixed on the described lower push-rod, be enclosed within the guide strip on the described push rod, described latch stretches out described guide strip, described guide strip is provided with the clamp of " fore-telling " font that comprises cross bar and montant, the cross bar of described clamp links to each other with described guide strip, described clamp can link to each other around the connecting portion that links to each other with described guide strip, the lower end of the montant of described clamp links to each other with described guide strip by spring, and the close described guide strip in the montant of described clamp upper end under the thrust of described spring is with described latch jack-up.
Implement push rod lock of the present invention, have following beneficial effect: because push rod lock link gear of the present invention is hidden in the doorframe, inner once pushing away out, the outside need use key just can open, and can guarantee safety, can conveniently use again; Push rod lock overall structure of the present invention is simple, and the reliability height is processed easyly, is easy to promote; Push rod lock of the present invention uses spring reset, as long as the door pushed home, dead bolt promptly inserts in the frame hole automatically, and the door body is pinned.
