[0019] like Figures 1 to 5As shown, an adjustable lock plate provided in this embodiment includes a panel 1, a rear cover 2, a fixed base 3, and an adjustable movable member 4. The rear cover 2 is fixedly connected to the panel 1, and the rear cover 2 is recessed inward to form a cavity 5 for accommodating the fixed base 3. The panel 1 is provided with one or more through holes 6 for the lock tongue to pass through, and the through holes 6 are connected to the cavity 5. The fixed base 3 is installed in at least one of the through holes 6 and is fixedly connected to the panel 1. The adjustable movable member 4 is installed on the fixed base 3, and the upper end surface of the adjustable movable member 4 is in contact with the bottom surface of the fixed base 3.
[0020] As described above, the fixed base 3 is provided with an irregular circular groove 31. The adjustable movable member 4 is provided with an adjusting screw mounting hole 41, in which an adjusting screw 42 is mounted, and the adjusting screw 42 passes through the adjusting screw mounting hole 41 and is connected with an irregular circular member 43 disposed on the bottom surface of the adjustable movable member 4, and the irregular circular member 43 is accommodated in the irregular circular groove 31. When the adjusting screw 42 is rotated, the irregular circular member 43 moves along the groove wall track of the irregular circular groove 31 and thereby pushes the adjustable movable member 4 to slide on the fixed base 3. Such a structural design makes it very simple and convenient when the door lock tongue clearance needs to be adjusted.
[0021] As described above, the irregular circular groove 31 is arranged on the fixed base plate 32. Such a structural design makes the adjustable moving member 4 more stable when moving on the fixed base 3.
[0022] As described above, the fixed base 3 includes a fixed bottom plate 32, a first vertical plate 33, a second vertical plate 34, and a third vertical plate 35. The first vertical plate 33 and the third vertical plate 35 are respectively located on both sides of the fixed bottom plate 32, and the second vertical plate 34 is located at the front side of the fixed bottom plate 32. Specifically, the adjustable moving member 4 is assembled in a concave cavity 36 surrounded by the fixed bottom plate 32, the first vertical plate 33, the second vertical plate 34, and the third vertical plate 35, and can slide in the concave cavity 36.
[0023] As described above, the adjustable movable member 4 comprises a bottom plate 44, a first side plate 45, a second side plate 46, a third side plate 47, and a guide piece 48, wherein the first side plate 45 and the third side plate 47 are respectively located at both sides of the bottom plate 44, the second side plate 46 is located at the front side of the bottom plate 44, the guide piece 48 is connected to the upper end of the second side plate 46 and extends laterally out of the side of the panel 1, and the end faces of the first side plate 45 and the third side plate 47 are stopped by the panel 1, and the adjustable movable member 4 can be prevented from falling off from the through hole 6. Specifically, the adjustable movable member 4 enclosed by the bottom plate 44, the first side plate 45, the second side plate 46, and the third side plate 47 is accommodated in the concave cavity 36, and the bottom plate 44 is attached to the fixed bottom plate 32, and the first side plate 45, the second side plate 46, and the third side plate 47 are respectively located at the inner sides of the corresponding first vertical plate 33, the second vertical plate 34, and the third vertical plate 35.
[0024] As described above, the fixing base 3 is further provided with a fixing hole 37 , and the panel 1 is provided with a through hole 11 . The fixing base 3 is fixed to the panel 1 by screws passing through the through hole 11 and the fixing hole 37 in sequence.
[0025] As mentioned above, there are four through holes 6 on the panel 1 and they are spaced apart from each other along the length extension direction of the panel 1 .
[0026] In summary, by rotating the adjusting screw 42, the irregular circular member 43 moves along the groove wall track of the irregular circular groove 31, and the adjustable movable member 4 can slide from the front side to the rear side of the fixed bottom plate 44 to reduce the gap of the through hole 6, thereby achieving a state where the through hole 6 is completely compatible with the door lock tongue. By rotating the adjusting screw 42 in the opposite direction, the adjustable movable member 4 can slide from the rear side to the front side of the fixed bottom plate 44 to increase the gap of the through hole 6, thereby achieving a state where the door lock tongue and the through hole 6 are completely compatible. Such a structural design makes it very simple and convenient to adjust the gap of the door lock tongue.
[0027] The above is only a preferred embodiment of the present utility model, and it cannot be used to limit the scope of the present utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the utility model description are still within the scope of the present utility model patent.
