Reversible lock body

Abstract

The invention relates to a reversible lock body comprising a lock body shell which is internally equipped with a containing cavity, and an inclined tongue and a square tongue which stretch out from one side of the lock body shell, wherein an unlocking shifting block capable of being driven by a key is arranged in the containing cavity; a rotary shifting block for driving the inclined tongue is arranged by means of being connected with the unlocking shifting block; a driving deflector rod is further arranged by means of being connected with the unlocking shifting block; a transmission bar which does a linear movement with the swinging of the driving deflector rod is arranged by means of being connected with the driving deflector rod; and one end of the transmission bar is connected with a first locking bar, and the other end of the transmission bar is connected with a second locking bar through a reversing gear assembly capable of changing the transmission direction of the transmissionbar. According to the reversible lock body, no extra reserving structure is added, and simultaneously, reverse driving of the first locking bar and the second locking bar is realized so that a door lock is locked in a vertical direction. Therefore, the cost is saved, and the reversible lock body is more convenient and fast to install and maintain and is a mechanical lock body with compact structure and good practicability.

Description

technical field [0001] The present invention relates to a mechanical lock, in particular to a reversible lock body. Background technique [0002] In the prior art, the mechanical lock installed on the door can lock the door by controlling the expansion and contraction of the oblique tongue and the square tongue. The oblique tongue and the square tongue move back and forth in the horizontal direction. In the door, the door lock not only needs to lock and cooperate with the door frame at the end face where the oblique tongue and square tongue are located, but also needs to be locked with the door frame at the top and bottom of the door, so as to achieve the effect of three-sided protection. In the prior art, the lock bar is generally driven by the transmission bar connected to the unlocking module, and finally the lock bar is inserted into the upper and lower parts of the door frame to lock the door in the vertical direction. In the above process, the lock bars inserted into ...

Problems solved by technology

In the prior art, the lock bar is generally driven by the transmission bar connected to the unlocking module, and finally the lock bar is inserted into the upper and lower parts of the door frame to lock the door in the vertical direction. In the above process, the lock bars inserted into the upper and lower parts of the door frame move in opposite directions, but in the current mechanical lock body, the drive bar drives the lock bar in only one direction, that is, the drive bar moves in a certain direction, and the lock bar also moves in the corresponding direction. Direction movement, in order to achieve the effect of different lock bars moving in opposite directions at the same time, people usually add a reversing mechanism outside the lock body, but adding a reversing structure not only increases the overall cost, but also needs to reserve additional space on the door body. space, extremely inconvenient during use
