Description

Technical Field

[0001] The utility model relates to the technical field of lock accessories, in particular to an armored door lock catch piece adjustment structure. Background Art

[0002] A lock refers to a device that performs a sealing function, which includes locks, keys and their accessories. It is generally interpreted as "a seal that can only be opened with a key." In addition to being opened with a key, a lock can also be opened with commands such as light, electricity, magnetism, sound and fingerprints.

[0003] A lock generally consists of a lock tongue and a lock catch. The lock catch limits the lock tongue and thus plays a locking role. During the actual installation of each door, there will often be deviations in the holes, or the operator will make certain errors when drilling holes in the wall, resulting in the entire door lock body being unable to be installed into the lock catch in the door frame. In this case, either the door lock has to be ground off or replaced, or the lock catch on the door frame has to be cut, which is time-consuming and laborious. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4, including a lock plate 1 and a lock box 2, an adjusting piece 3, installed inside the lock box 2; an adjusting slot 7, opened on the surface of the adjusting piece 3 close to the lock plate 1, and the adjusting slot 7 is a waist-shaped hole structure; an adjusting device, installed inside the adjusting slot 7; and a fixed gear 2 10, fixed on both sides of the inner wall of the adjusting slot 7. The adjusting device includes an adjusting rod 8, a fixed gear 1 9, an eccentric wheel 11, and a paddle 12, wherein the adjusting rod 8 is installed inside the adjusting slot 7, the fixed gear 1 9 is fixed on the outer wall surface of the adjusting rod 8, and the fixed gear 1 9 and the fixed gear 2 10 can mesh with each other, the eccentric wheel 11 is fixed on the side of the adjusting rod 8 away from the lock plate 1, and the outer ring of the eccentric wheel 11 is in contact with the side wall of the adjusting piece 3, the diameter of the eccentric wheel 11 is larger than the diameter of the adjusting slot 7, so that the eccentric wheel 11 cannot pass through the inside of the adjusting slot 7, and the paddle 12 is fixed on the side of the adjusting rod 8 away from the eccentric wheel 11, and when adjusting the position of the adjusting piece 3, the paddle 12 is used to adjust the position of the adjusting piece 3. Pull the adjusting rod 8 upward to stagger the fixed gear teeth 1 9 and the fixed gear teeth 2 10, so that the adjusting rod 8 can drive the eccentric wheel 11 to rotate. When the adjusting rod 8 rotates, due to the change in the center position of the eccentric wheel 11, the eccentric wheel 11 pushes the adjusting piece 3 through the side wall, thereby changing the position of the adjusting piece 3. When the adjusting piece 3 is adjusted, the position of the adjusting rod 8 inside the adjusting groove 7 changes. The adjusting rod 8 is reinserted into the adjusting groove 7 to make the fixed gear teeth 1 9 and the fixed gear teeth 2 10 plug into each other, so that the adjusting rod 8 is fixed in position, and the fixed gear teeth 2 10 is placed to rotate automatically, thereby further fixing the position of the adjusting piece 3.

[0025] When the adjusting rod 8 is located at the side of the adjusting groove 7 away from the adjusting piece 3, the pressure on the compression spring 5 is reduced, and the compression spring 5 moves the adjusting piece 3 in the direction of the adjusting groove 7 by pushing the push plate 6, thereby changing the position of the adjusting piece 3. When the adjusting rod 8 is located at the side of the adjusting groove 7 close to the adjusting piece 3, the side wall of the eccentric wheel 11 is against the outer wall of the adjusting piece 3, and the adjusting piece 3 is pushed by the eccentric wheel 11 to move in the direction of the installing box 4. When the adjusting piece 3 moves, the compression spring 5 is compressed by the push plate 6, so that the push plate 6 moves its position, so that the adjusting piece 3 can change its position.

[0026] An active hole 13 is provided on the surface of the lock plate 1. After the lock plate 1 and the adjustment plate 3 are assembled, the paddle 12 at the end of the adjustment rod 8 is installed inside the active hole 13, and the position of the adjustment rod 8 is limited by the active hole 13. A baffle 14 is movably installed on the top of the active hole 13, and the position of the active hole 13 is closed by the baffle 14, so as to reduce the damage of the adjustment device to the outside world and contribute to the overall beauty of the lock plate 1. When adjusting the adjustment plate 3, the baffle 14 is rotated through the rotating shaft to stagger the baffle 14 and the active hole 13, so as to expose the inside of the active hole 13, so as to operate the adjustment device.

[0027] Working principle: when adjusting the position of the adjusting piece 3, the blocking piece 14 is rotated to one side of the movable hole 13 to expose the paddle 12 inside the movable hole 13, and the paddle 12 is lifted up by the tool to disengage the fixed gear tooth 1 9 on the surface of the adjusting rod 8 from the fixed gear tooth 2 10 inside the adjusting groove 7. At this time, the adjusting piece 3 is pushed by the push plate 6 to move in the direction of one side of the adjusting groove 7. According to the position to be adjusted of the adjusting piece 3, the adjusting rod 8 is rotated to make the side wall of the eccentric wheel 11 push the side wall of the adjusting piece 3 to move, thereby moving the adjusting piece 3 in the direction of the installation box 4. After the adjusting piece 3 reaches the predetermined position, the paddle 12 is pressed in the direction of the lock box 2 to make the fixed gear tooth 1 9 and the fixed gear tooth 2 10 re-engage, thereby fixing the direction and position of the eccentric wheel 11. After the eccentric wheel 11 is fixed, the adjusting piece 3 is also fixed, and the other side of the adjusting piece 3 is against the push plate 6, which also restricts the movement. At this time, the adjusting piece 3 completes the position adjustment.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
