Description
Technical Field
The invention relates to the field of lock bodies, in particular to a lock body capable of being unlocked in a bidirectional linkage mode.
Background
At present, mortise locks in the market are generally opened by rotating a handle inside or outside a pressing door to unlock a lock tongue. In the process of installing the anti-theft door, two conditions of opening the door left and opening the door right exist; in order to meet the two installation requirements, the lock body is usually set to be suitable for two specifications of a left opening door and a right opening door, or the installation requirement of the door is met by changing the direction on site. Therefore, not only is inconvenience brought to the batch production of a factory, but also the installation process of the lock is complicated.
Therefore, how to design a lock body which can be opened without left and right opening becomes a technical problem to be solved urgently by the technical personnel in the field.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides the lock body capable of being unlocked in a two-way linkage manner, so that the lock body can meet two installation requirements of a left door and a right door simultaneously, and the applicability of the lock body is improved.
The technical scheme adopted by the invention for solving the problems is as follows:
a lock body capable of being unlocked in a two-way linkage mode comprises a lock shell, a poking plate and a rotating block, wherein the poking plate is rotatably connected with the lock shell;
when the rotating block rotates upwards/downwards, the poking plate can be driven to rotate downwards.
Therefore, when the rotating block rotates upwards/downwards, the poking plate can be driven to rotate downwards, and the lock tongue is unlocked. The lock body can meet two installation requirements of a left door and a right door, the applicability of the lock body is improved, and the production cost is reduced.
Furthermore, a flange is convexly arranged on the rotating block, and a convex block is arranged on the poking plate; when the rotating block rotates upwards, the flanges are abutted against the convex blocks and drive the poking plate to rotate downwards;
a first swing arm is arranged on the rotating block; when the rotating block rotates downwards, the first swing arm is abutted to the poking plate and drives the poking plate to rotate downwards.
Further, the unlocking structure further comprises a bolt assembly, a connecting plate, a lateral stop and a lateral stop spring, wherein:
the lateral stop block is arranged on the connecting plate;
the lock bolt assembly comprises a lock bolt and a lock bolt positioning block, and the lateral stop block is abutted against the lock bolt positioning block through the lateral stop block spring to lock the lock bolt;
the spring bolt unlocking device is characterized in that a second swing arm is arranged on the poking plate, an extending plate is arranged on the connecting plate, and when the poking plate rotates downwards, the second swing arm is abutted to the extending plate and drives a lateral stop block on the connecting plate to be separated from the spring bolt positioning block, so that the spring bolt is unlocked.
Further, the lateral stop spring comprises a spring body, a first protruding end and a second protruding end, wherein:
the first extending end and the second extending end are respectively arranged on two sides of the spring body;
the spring body and the second extending end are both connected to the lock shell, and the first extending end is connected to the lateral stop block.
Therefore, when the toggle plate does not rotate, namely the second swing arm is not abutted to the extension plate, the lateral stop block abuts to the abutting groove of the bolt positioning block under the elastic acting force of the lateral stop block spring, and the bolt is locked.
Furthermore, the spring bolt assembly further comprises a first return spring, one end of the first return spring is connected with the spring bolt positioning block, and the other end of the first return spring is connected with the lock shell.
From this, through setting up first reset spring, this spring bolt can stretch out outside the lock shell all the time under first reset spring's elastic force.

the third extending end and the fourth extending end are respectively arranged on two sides of the reset spring body;
the reset spring body and the third extending end are connected to the poking plate;
the lock shell is provided with a second positioning column and a third positioning column, the fourth extending end is abutted against the second positioning column, and the toggle plate is abutted against the third positioning column.
Therefore, when the toggle plate does not rotate, the toggle plate abuts against the third positioning column under the elastic force of the second return spring, the second swing arm on the toggle plate does not abut against the extension plate on the connecting plate, and the lateral stop block abuts against the abutting groove of the bolt positioning block under the elastic force of the lateral stop block spring, so that the locking of the bolt is realized.
Furthermore, a first boss and a second boss are arranged on the poking plate, the reset spring body is sleeved on the first boss, and the third extending end is wound on the second boss.
Furthermore, an arc surface is arranged on the poking plate close to the third positioning column and abuts against the third positioning column.
Therefore, the stability of the poking plate abutting against the third positioning column can be improved by arranging the arc surface.
Furthermore, a mounting groove is formed in the lateral stop block, and a vertical plate capable of being inserted into the mounting groove is arranged on the connecting plate.
Therefore, the vertical plate on the connecting plate is inserted into the mounting groove, and the lateral stop block is mounted on the connecting plate.
Furthermore, a lock hole for inserting the handle mandrel is formed in the rotating block.
In summary, according to the lock body unlocked through bidirectional linkage provided by the invention, when the handle is rotated up/down and pressed down, the spindle on the handle drives the rotating block to rotate up/down; when the rotating block rotates upwards/downwards, the poking plate can be driven to rotate downwards, so that the lateral stop block on the connecting plate is driven to be separated from the abutting groove, and the lock tongue is unlocked. The lock body can meet two installation requirements of a left door and a right door, the applicability of the lock body is improved, and the production cost is reduced.
