Description

Embedded rolling shutter door lock Technical Field The utility model relates to an embedded roller shutter door lock basin. Background The rolling door is widely applied to various places such as commercial shops, warehouses, banks and the like by virtue of the characteristics of high space utilization rate and strong anti-theft property. The rolling door lock is used as a core component for guaranteeing the safety of the rolling door, and the structural rationality, the installation convenience and the operation stability of the rolling door directly influence the use effect of the rolling door. The existing roller shutter door locks mostly adopt structures such as ground hook locks, side-mounted locks and the like, and have a plurality of defects. The ground hook lock needs to be pre-buried in the ground slotting, so that the ground decoration is damaged, sundries are easy to accumulate in the slots, the locking fault is caused by water accumulation, the potential safety hazard of a stumbled pedestrian exists, and the ground hook lock needs to be fixed by extra quick-drying cement during installation, so that the operation is complex. The side-mounted lock is loose in structure and easy to deform due to the fact that the lock body is exposed outside, and the side-mounted lock is required to fix the rolling door body and the wall body in multiple points during installation, so that the assembly efficiency is low. Part of improved locksets try to optimize the structural compactness, but still do not deviate from the traditional installation mode, and the integrated adaptation of the lock body and the rolling shutter door track cannot be realized, so that the overall stability after installation is poor, and the problems of bolt deviation, clamping stagnation and the like are easy to occur after long-term use. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an embedded roller shutter door lock which is simple in structure, convenient and reliable to assemble, strong in structural stability and good in use effect. In order to achieve the above purpose, the utility model provides an embedded roller shutter door lock, which comprises a lock shell, a positioning piece and a lock pin arranged on the roller shutter door, wherein the positioning piece comprises a jointing part, a collision part and a connecting part for positioning a roller shutter door track, which are sequentially connected, the jointing part is collided on one side wall of the lock shell, the collision part is collided on the other side wall of the lock shell, the jointing part is perpendicular to the collision part, the connecting part is perpendicular to the collision part, a connecting hole for fixedly connecting the track is formed in the connecting part, a lock tongue is arranged on the lock shell, a collision inclined plane for being collided by the lock pin and retracting into the lock shell and a limiting surface for being collided on the lock pin side wall to limit the lock pin from sliding are arranged on the lock pin, a push spring for enabling the lock tongue to be kept outside the lock shell is collided between the lock tongue and the lock shell, and a driving mechanism for driving the lock tongue to retract into the lock shell is also arranged in the lock shell. The integrated positioning fixing device has the advantages that the integrated positioning fixing of the lock shell and the rolling shutter door track is realized through the positioning piece, the ground grooving pre-embedding is not needed to be damaged like a ground hook lock, the complex operation of multi-point fixing of the side-mounted lock is avoided, the assembly efficiency is greatly improved, the joint part and the abutting part form bidirectional abutting limit on the lock shell, the accurate positioning and no looseness after the lock shell is mounted are ensured, and the problem of bolt deflection easily occurring in long-term use of a traditional lock is radically solved. The roller shutter door can be stably installed without additional fixing pieces, the material cost and the construction difficulty are reduced, roller shutter door rails with different specifications are adapted, and the universality is higher; the push spring always keeps the extending state of the lock tongue, and cooperates with the driving mechanism to realize unlocking, the whole structure is simple and compact, the embedded installation requirement is adapted, and the defect that the side-mounted lock body is exposed and easy to be impacted and deformed is effectively avoided. As a further arrangement of the utility model, the driving mechanism comprises a driving motor and a swinging piece, the swinging piece is connected to the output end of the driving motor, a swinging arm is arranged on the swinging piece, a driving groove is formed in the side wall of the lock tongue, and the swinging arm is abutted against the side wall of the dri
