The cam component 2 is connected with the base 1 through a torsion spring, namely the torsion spring is sleeved on a rotating shaft 6 of the cam component 2 in a conventional mode, one end of the torsion spring is connected with the cam component 2, and the other end of the torsion spring is connected with the base 1; the torsion spring has a biasing force that keeps the cam assembly 2 rotating in the unlocking direction when the cam assembly 2 is in the locked position.
As shown in fig. 4, a sliding abutment block 10 is slidably and elastically connected in the base 1, the sliding abutment block 10 is connected to the base 1 by a slider elastic member, and the sliding abutment block 10 is horizontally disposed at the rear of the cam assembly 2, i.e., at a side away from the cam assembly 2, for driving the sliding abutment block 10 to move toward the cam assembly 2. The sliding abutment block 10 has, on the side facing the cam module 2, a sliding surface 11 for pushing against the bolt 8 before the rotation of the cam module 2 to the locking position and a vertical surface 12 for blocking the bolt 8 after the rotation of the cam module 2 to the locking position. During the rotation of the cam module 2 towards the locking position driven by the door hook 25, when the cam module 2 is rotated to a predetermined position before the locking position, the stud 8 collides with the sliding surface 11, and the stud 8 passes the sliding surface 11 and reaches the rear of the vertical surface 12, so that it can be caught on the vertical surface 12.
As shown in fig. 5, one end of the lock catch 3 has a locking structure 13, and the other end is connected with a positioning rod 14; one end of the positioning rod 14 is rotatably connected with the base 1, and the other end of the positioning rod is connected with the lock catch 3 through a twisting structure 16; the twist-on structure 16 allows the latch 3 to move back and forth, swing left and right, and swing up and down in the direction of the cam assembly 2.
As shown in fig. 6, an unlocking slide block 15 is slidably disposed in the base 1, one end of the unlocking slide block 15 is connected with an electromagnetic driving device of a door lock, and the other end is connected with the middle part of the lock catch 3; the unlocking slide block 15 is driven by the driving device to push the lock catch 3 to swing in the left-right direction, i.e. the sliding direction of the unlocking slide block 15, towards the direction away from the cam assembly 2.
As shown in fig. 7, a lever 17 is rotatably connected in the base 1, and the lever 17 has an abutment surface 18 for blocking the cam module 2 from rotating in the unlocking direction. The abutment surface 18 is a ramp surface adapted to cooperate with a snap-in surface 19 of the upper catch portion of the cam module 2. The abutment surface 18 is parallel to the snap-in surface 19 and thus abuts below the snap-in surface 19 when the cam module 2 is in the locked position; further, since the abutment surface 18 is a slope, the force of locking the cam module 2 by the lever 17 can be increased, and the cam module 2 is less likely to be turned over when the cam module 2 is locked.
As shown in fig. 8, a spring fixing piece 20 is connected to the base 1 by insertion, a first elastic piece 21 is connected between the spring fixing piece 20 and the positioning rod 14, and the first elastic piece 21 has a biasing force that deflects the positioning rod 14 in a direction away from the cam module 2.
As shown in fig. 9, a protruding block 22 is provided above the spring fixing plate 20, the protruding block 22 is in sliding contact with the bottom of the latch 3, a contact surface in sliding fit with the protruding block 22 is provided at the bottom of the latch 3, and the contact surface is provided with an inclined surface 23; when the latch 3 moves forward toward the cam assembly 2, the protrusion 22 slides along the contact surface of the latch 3 toward the inclined surface 23, thereby lifting the latch 3 upward and tilting the latch 3. In addition, as an alternative embodiment, the projecting block 22 may also be provided on other parts of the base 1.
Application method
As shown in fig. 8, the door hook 25 is not inserted into the push type door lock, and the door lock is in a free state. At this time, the bayonet 7 of the cam component 2 faces downward, namely, the direction of the door hook 25 under the action of the torsion spring; the lever 17 is located on the side of the bayonet opening 7 of the cam module 2 and is intended to engage with the snap-in surface 19 of the upper snap-in part of the cam module 2. The latch 3 is kept horizontal at this time, and the rear end thereof is connected to the positioning rod 14 by a kink structure.
As shown in fig. 10, after the door hook 25 is inserted into the push-type door lock, the door lock is in a locked state, at this time, the door hook 25 is inserted into the bayonet 7 of the cam assembly 2, the cam assembly 2 is driven to rotate upward by the door hook 25, the snap-in surface 19 of the upper snap portion of the cam assembly 2 is brought into contact with the lever 17, and the cam assembly 2 is locked at this position; and above the cam member 2, the latch 3 locks the cam member 2 by the latch structure 13. Behind the latch 3, a positioning rod 14 is connected to the latch 3 by a twist-joint structure 16, and the positioning rod 14 is pushed against a state of pulling the latch 3 rearward by a spring fixing piece 20 and a first elastic piece 21.
As shown in fig. 9, when the door hook 25 is pulled out from the push type door lock, the door lock releases the locking of the door hook 25 by the child lock function, and at this time, the cam assembly 2 is driven to rotate when the door hook 25 is forcibly pulled out, and the lever 17 is pushed by the cam assembly 2 to rotate, and the abutment with the lever 17 is released; on the other hand, above the cam assembly 2, the latch 3 moves forward along with the cam assembly 2 under the cooperation of the locking structure 13, that is, moves laterally toward the rotation direction of the cam assembly 2, and during the forward movement of the latch 3, the inclined surface 23 below the latch 3 slides along the protruding block 22 of the spring fixing piece 20, so that the end of the latch 3 having the locking structure 13 is tilted upward, thereby releasing the locking of the locking structure 13 on the cam assembly 2, and enabling the cam assembly 2 to be unlocked and turned over smoothly.
