Preferably, a torsion spring 6 is arranged at the hinged part of the connecting rod 5 and the lock body 1, the connecting rod 5 rotates under the torsion force of the torsion spring 6 to enable the pushing bolt 4 to slide towards the outside of the lock body 1, and the stopping bolt 3 slides into the lock body 1 under the linkage action of the connecting rod 5.
Preferably, the locking tongue 3 includes a sleeve 31 sliding left and right on the lock body 1 and an insert 32 sliding left and right on the sleeve 31, a limit sliding groove 33 is formed on a sliding side surface of the insert 32, a limit boss 34 disposed in the limit sliding groove 33 is disposed on the sleeve 31, a spring 35 disposed on the right side of the insert 32 and contacting with the insert 32 is disposed in the sleeve 31, and the insert 32 slides left under the elastic force of the spring 35, that is, the outer part of the lock body 1 slides to press and contact the limit boss 34 with the right end surface of the limit sliding groove 33.
Preferably, the two ends of the connecting rod 5 are respectively provided with a straight groove 7, the right ends of the stopping bolt 3 and the pushing bolt 4 are respectively provided with a hinged shaft 8, the hinged shafts 8 are arranged in the corresponding straight grooves 7, when the connecting rod 5 rotates, the straight grooves 7 push the hinged shafts 8 to generate displacement in the left-right direction and the hinged shafts 8 slide in the straight grooves 7, so as to compensate the distance change between the stopping bolt 3 and the pushing bolt 4 and the middle part, namely the rotating part, of the connecting rod 5, and thus the linkage effect of the connecting rod 5 is smooth and stable.
Preferably, the right ends of the stopping bolt 3 and the pushing bolt 4 are respectively hinged with a swing rod, the two ends of the connecting rod 5 are respectively hinged with the swing end parts of the two swing rods, when the connecting rod 5 rotates, the stopping bolt 3 and the pushing bolt 4 slide in opposite directions, so that the distance between the stopping bolt 3 and the pushing bolt 4 and the middle part of the connecting rod 5, namely the rotating part, changes, and the swing rods swing on the corresponding stopping bolt 3 and the corresponding pushing bolt 4 to compensate the distance change, so that the linkage effect of the connecting rod 5 is smooth and stable.
When the door lock is used, the lock body 1 is arranged on the door body to be used, and the locking and unlocking operation of the door lock is the same as the operation mode of a conventional door lock.
