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 getting into.
Summary of the invention
The technical problem that the present invention will solve is that the above-mentioned defective to 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; Said push rod with can drive the linkage that said push rod moves up and down and link to each other, also comprise driving the dead man that said linkage rotates; Said push rod comprises the upper push-rod that inserts upper door frame respectively and the lower push-rod that inserts lower door frame, between said upper push-rod and the lower push-rod through can drive said upper push-rod and lower push-rod in opposite directions or the linkage that moves dorsad link to each other.Also be included in door opening state and be used for resetting-mechanism that said lower push-rod jack-up is not fallen; Said resetting-mechanism comprises the latch that is fixed on the said lower push-rod; Be enclosed within the guide strip on the said lower push-rod, said latch stretches out said guide strip, and said guide strip is provided with the clamp of " fore-telling " font that comprises cross bar and montant; The cross bar of said clamp links to each other with said guide strip; Said clamp can rotate around the connecting portion that links to each other with said guide strip, and the lower end of the montant of said clamp links to each other with said guide strip through spring, the montant of said clamp under the thrust of said spring near said guide strip with said latch jack-up.
The push rod lock of embodiment of the present invention has 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 reliability is high, process easyly, is easy to popularization; 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, pins the door body.
