referring to fig. 7 and 8, the lock device 60 includes: the device comprises a lifting movable base 100, a deflection adjusting mechanism 200, an unlocking mechanism 300 and a locking pin mechanism 400.
The movable lifting base 100 is movably mounted on the door panel 50. The movable base 100 is installed on the door 50 to be movable up and down, and will be described in more detail below.
As shown in fig. 8, the yaw adjustment mechanism 200 includes a rotary disk 210 and a yaw knob 220. The rotary disk 210 is rotatably disposed on the lifting movable base 100, the rotary disk 210 is a circular ring structure, the rotary disk 210 has an inner ring gear 211 and an outer ring gear 222 (as shown in fig. 9), and the yaw knob 220 is engaged with the outer ring gear 222 of the rotary disk 210 through an outer gear 230.
As shown in fig. 8 and 10, the unlocking mechanism 300 includes: a reciprocating rod 310, a manual rocker 320, and an inner gear 330. The reciprocating rod 310 is disposed on the movable base 100 in a manner capable of reciprocating along a horizontal direction, the reciprocating rod 310 has a guide rail 311, and a slider 340 is slidably disposed in the guide rail 311. The manual rocker 320 is rotatably disposed on the lifting movable base 100, the internal gear 330 is engaged with the internal gear 211 of the rotary wheel 210, the manual rocker 320 is connected with the internal gear 330 through the first connecting rod 350, and the internal gear 330 is connected with the slider 340 through the second connecting rod 360.
As shown in fig. 8, the latch mechanism 400 includes a latch body 410 and a return spring 420. The lock pin body 410 is disposed on the door panel 50 to be capable of sliding back and forth in a horizontal direction, the protection frame 40 is formed with a locking groove (not shown) engaged with the lock pin body 410, and the return spring 420 is used for providing an elastic restoring force to the lock pin body 410 so that one end of the lock pin body 410 enters the locking groove.
The reciprocating rod 310 is provided with a one-way toggle member 500 (as shown in fig. 7), the lifting movable base 100 is provided with a one-way limiting member 600 (as shown in fig. 7), and the lock pin body 410 is provided with a one-way ratchet 411 (as shown in fig. 7) engaged with the one-way toggle member 500 and the one-way limiting member 600. Specifically, the one-way toggle 500 includes a one-way toggle wedge 510 and a first return spring 520 for providing an elastic restoring force to the one-way toggle wedge 510; the one-way limiting member 600 includes a one-way limiting wedge 610 and a second return spring 620 for providing elastic restoring force to the one-way limiting wedge 610; the one-way ratchet 411 has a straight tooth arrangement structure.
Before explaining the operation principle of the lock body device 60, the movement traces of the main components of the lock body device 60 are explained:
the adjustment of the reciprocating rod 310 can be realized by the yaw adjusting mechanism 200, so that the reciprocating rod 310 can slide on the lifting movable base 100 in a reciprocating manner along the horizontal direction, and further, the guide rail 311 on the reciprocating rod 310 is just positioned at the center position of the rotating wheel disc 210 (as shown in fig. 11), or the guide rail 311 on the reciprocating rod 310 is positioned at the non-center position of the rotating wheel disc 210 (as shown in fig. 12); for example, the swing knob 220 is screwed, the swing knob 220 drives the rotating wheel disc 210 to rotate through the matching of the external gear 230 and the external gear ring 222, the rotating wheel disc 210 further drives the internal gear 330 to rotate through the internal gear ring 211 (it is noted that, by screwing the swing knob 220, the internal gear 330 simply rotates, but does not revolve around the rotating wheel disc 210), the internal gear 330 further drives the slider 340 to slide along the guide rail 311 through the second link 360, and during the sliding process of the slider 340 along the guide rail 311, the second link 360 drives the reciprocating rod 310 to slide on the lifting movable base 100 through the slider 340, so that the reciprocating rod 310 can be adjusted to the central position (as shown in fig. 11) or the non-central position (as shown in fig. 12) of the rotating wheel disc 210;
as shown in fig. 13, when the reciprocating rod 310 is located at the center of the rotating wheel 210, the manual rocker 320 is rotated, the manual rocker 320 drives the internal gear 330 to roll around the internal gear 211 of the rotating wheel 210 through the first connecting rod 350, the internal gear 330 rolling around the internal gear 211 drives the slider 340 to slide along the guide rail 311 in a reciprocating manner through the second connecting rod 360, because the guide rail 311 on the reciprocating rod 310 is located at the center of the rotating wheel 210 (i.e. the guide rail 311 at this time is located right through the central axis of the rotating wheel 210), the second connecting rod 360 cannot drive the reciprocating rod 310 to slide on the lifting movable base 100 in a reciprocating manner through the slider 340, and the reciprocating rod 310 at this time is in a stationary state;
as shown in fig. 14, when the reciprocating rod 310 is located at a non-central position of the rotating wheel 210 (it should be particularly noted that, due to the matching relationship between the one-way toggle 500 and the one-way ratchet 411, the one-way toggle 500 can only drive the lock pin body 410 to move in one direction, so that when the reciprocating rod 310 moves a certain distance to one side, the one-way toggle 500 on the reciprocating rod 310 does not drive the lock pin body 410 to move), and then, the manual rocker 320 rotates, the manual rocker 320 drives the inner gear 330 to roll around the inner gear 211 of the rotating wheel 210 through the first connecting rod 350, the inner gear 330 rolling around the inner gear 211 drives the slider 340 to slide back and forth along the guide rail 311 through the second connecting rod 360, because the guide rail 311 on the reciprocating rod 310 is located at a non-central position of the rotating wheel 210 (i.e. the reciprocating rod 310 swings to one side, the guide rail 311 does not pass through a central axis of the rotating wheel 210, the reciprocating rod 310 has a condition of reciprocating sliding), therefore, the second connecting rod 360 drives the reciprocating rod 310 to slide on the movable lifting base 100 through the sliding block 340, and the reciprocating rod 310 is in a reciprocating state at this time;
it should be particularly noted that the rotating wheel 210 can be finally driven to rotate only by screwing the swing knob 220; while the inner gear 330 does not rotate the rotary disk 210 while rolling around the inner gear 211 of the rotary disk 210.
The operation principle of the lock body device 60 will be explained as follows:
when the latch mechanism 400 is in the locked state, one end of the latch body 410 enters the lock slot of the protection frame 40, and at this time, the guide rail 311 on the reciprocating rod 310 is located right at the center of the rotating wheel disc 210 (as shown in fig. 11), and no matter how the manual rocker 320 is rotated, the reciprocating rod 310 does not slide on the movable lifting base 100 in a reciprocating manner (as shown in fig. 13 and 15), and thus the unlocking cannot be smoothly performed;
next, it is necessary to unlock so that one end of the lock pin body 410 is separated from the lock groove of the protection frame 40, and thus the door panel 50 can be opened;
at this time, it is necessary to move the guide rail 311 of the reciprocating rod 310 to a non-central position of the rotary disk 210 (as shown in fig. 12) so that the reciprocating rod 310 has a condition of reciprocating sliding;
as shown in fig. 14, after the guide rail 311 of the reciprocating rod 310 moves to the non-central position of the rotating wheel disc 210, the manual rocker 320 can be rotated, the manual rocker 320 drives the inner gear 330 to roll around the inner gear ring 211 of the rotating wheel disc 210 through the first connecting rod 350, the inner gear 330 rolling around the inner gear ring 211 drives the sliding block 340 to slide along the guide rail 311 in a reciprocating manner through the second connecting rod 360, and the sliding block 340 sliding in a reciprocating manner along the guide rail 311 drives the reciprocating rod 310 to slide in a reciprocating manner;
as shown in fig. 16, during the reciprocating sliding of the reciprocating rod 310, the reciprocating rod 310 drives the lock pin body 410 to move to one side through the cooperation of the one-way toggle piece 500 and the one-way ratchet 411, so that one end of the lock pin body 410 is disengaged from the lock slot, thereby unlocking the lock;
it should be noted that, because the reciprocating rod 310 has the characteristic of reciprocating movement, the one-way toggle 500 is specially designed to cooperate with the one-way ratchet 411, so that the reciprocating rod 310 moving to one side will not drive the lock pin body 410 to move, and the reciprocating rod 310 moving to the opposite direction can drive the lock pin body 410 to move;
referring to fig. 7 and 8, it is further described that a return spring 420 is disposed on the lock pin body 410, the return spring 420 is used for providing an elastic restoring force for the lock pin body 410, and in the process of unlocking the lock pin body 410 by using the reciprocating rod 310, in order to prevent the lock pin body 410 from being reset, a one-way limiting member 600 is particularly disposed on the movable lifting base 100, and each time the lock pin body 410 moves a short distance and stops temporarily, the one-way limiting member 600 falls into the one-way ratchet 411, so as to stably limit the lock pin body 410 and prevent the lock pin body 410 from being reset;
as shown in fig. 17, when the lock needs to be locked again, the door panel 50 is closed, and then the lifting movable base 100 is lifted, the one-way toggle piece 500 and the one-way limiting piece 600 lift together with the lifting movable base 100 to disengage from the one-way ratchet 411, and the lock pin body 410 is no longer bound and is free, so that the lock pin body 410 is reset under the action of the reset spring 420 and enters the lock slot again;
when the door panel 50 is locked again, the lifting movable base 100 is lowered and reset, so that the one-way toggle piece 500 and the one-way limiting piece 600 are clamped on the one-way ratchet 411 again;
in order to prevent the door panel 50 from being easily opened, the swing knob 220 is turned so that the reciprocating lever 310 is re-centered on the rotary disk 210, and thus, even if the manual rocker 320 is turned, the latch body 410 is not separated from the latch groove since the reciprocating lever 310 is not moved.
Further, the lock device 60 further includes a base lifting adjusting member 700 (as shown in fig. 10), and the base lifting adjusting member 700 is drivingly connected to the lifting movable base 100, so that the lifting movable base 100 can move on the door panel 50 in a lifting manner, and the one-way toggle member 500 and the one-way limiting member 600 can move close to or away from the one-way ratchet 411.
Specifically, the base lifting adjusting member 700 is an eccentric rotating rod rotatably disposed on the door plate 50, and the lifting movable base 100 is connected to a non-central axis position of the eccentric rotating rod. Thus, since the movable elevation base 100 is provided at an eccentric position of the eccentric rotary rod, the movable elevation base 100 can be elevated as long as the eccentric rotary rod is rotated.
It should be further noted that, since the swing adjusting mechanism 200 is also provided on the movable lifting base 100, the swing adjusting mechanism 200 will move up and down along with the movable lifting base 100. For this purpose, in particular, an escape groove 51 (as shown in fig. 4) is formed in the door plate 50, the swing knob 220 is connected to the external gear 230 through the escape groove 51 of the door plate 50, and the escape groove 51 allows the swing knob 220 to have a sufficient movement space.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
