Problems solved by technology
Although the oblique bolt with this structure solves the practicability problem of the oblique bolt relatively well, the top wall of the rod body of the oblique bolt is plate-shaped, and the stability of the action deviates and it has been used for 100,000 times. After the above, there will be deformation, which is not suitable for long-term use

[0021] Such as figure 1 As shown, there is a lock body 1 with an improved deadbolt connecting rod. The lock body 1 includes a lock housing 11, and a deadbolt 2, a deadbolt connecting rod 3, and a driving bolt are arranged in the lock housing 11. The spring 12 that the connecting rod 3 moves up, the dial 14 that can drive the retraction of the deadbolt connecting rod 3 , and the handle square iron connecting block 13 that can drive the rotation of the dial 14 . Wherein the front wall of the lock housing 11 is provided with an opening capable of extending or retracting the lock tongue 2 . For this reason, the deadbolt link 3 can drag the deadbolt 2 to extend and retract in the opening.
[0022] Such as figure 2 , image 3 , Figure 4 and Figure 5 As shown, the deadbolt connecting rod 3 includes a cross arm portion 302 and a vertical arm portion 301 substantially perpendicular to the cross arm portion 302, and a positioning boss 30 is provided at the tail end of the dead b...

The invention relates to a lock body with an improved lock tongue connecting rod. The lock body comprises a lock shell body, a lock tongue capable of stretching out and drawing back in an opening portion of one side of the lock shell body, and the lock tongue connecting rod capable of dragging the lock tongue to move, wherein the lock tongue connecting rod is located in the lock shell body. The lock tongue connecting rod comprises a transverse arm and a vertical arm roughly perpendicular to the transverse arm, and the lock tongue is connected to the transverse arm. The lock body is characterized in that the lock tongue connecting rod comprises a first connecting rod body and a second connecting rod body formed in a molding mode and capable of being horizontally spliced together; the first connecting rod body is provided with a first transverse arm body and a first vertical arm body, and the second connecting rod body is provided with a second transverse arm body and a second vertical arm body; the first transverse arm body and the second transverse arm body are horizontally spliced together to form the transverse arm, and the first vertical arm body and the second vertical arm body are horizontally spliced together to form the vertical arm. Due to the fact that the lock body has the characteristics and advantages, the lock body can be applied to lock body products of mortice door locks.
Description
technical field [0001] The invention relates to a mortice door lock, in particular to a lock body of a mortice door lock with an improved deadbolt link structure. Background technique [0002] The structure of the lock tongue, the most common structure is that the lock tongue and the rod-shaped lock tongue connecting rod are thermally extruded and connected together, that is, the central part of the lock tongue is provided to allow the lock to The top end of the tongue connecting rod is inserted into the hole, and the top end of the dead bolt connecting rod is thermally extruded into the hole so as to be reliably connected. The biggest problem with this structure is that the deadbolt connecting rod is located on the central axis of the deadbolt head, and since the diameter of the deadbolt connecting rod is relatively large, it needs to occupy more space in the lock housing. exercise space. But for the lock body that needs to utilize the space behind the dead bolt, this str...
