For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication between two devices, elements or components.

[0026] For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] With regard to the drawings of the present application, it should be clearly understood that the drawings are only for illustrative and descriptive purposes, and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0028] As Figures 1 to 6 shown, a simple adjustable door buckle plate is provided in the present specification, comprising a fixed support 1, a face cover plate 2, a rotating adjusting part 3 and an adjusting cam 4, the fixed support 1 is used to be fixed with the door frame, the fixed support 1 is provided with an adjusting hole 100, the face cover plate 2 is provided with a lock hole 200, the side of the fixed support 1 away from the face cover plate 2 is provided with an adjusting groove 101, the rotating adjusting part 3 is rotationally arranged on the face cover plate 2, one end thereof passes through the adjusting hole 100 and is slidingly matched therewith, and is connected with the adjusting cam 4, that is, the adjusting cam 4 is eccentrically connected with the rotating adjusting part 3, the adjusting cam 4 rotates synchronously with the rotating adjusting part 3, and the outer wall thereof is linked with the left and right side walls of the adjusting groove 101, when the rotating adjusting part 3 is rotated, the adjusting cam 4 rotates synchronously, driving the face cover plate 2 to move left and right, so that the lock hole on the door buckle plate can be adjusted horizontally, solving the problem that the traditional door buckle plate cannot adjust the position, effectively adapting to the deformation, position deviation and the like of the door body or the door frame or the lock due to installation error or long-term use, and ensuring the stability and reliable closure of the door lock system.

[0029] Secondly, the traditional fixed door buckle plate needs to be individually customized according to the thickness, material and specific requirements of the lock of the door body, resulting in increased production cost and complexity. However, the simple adjustable door buckle plate in the present technical solution can adapt to different specifications of the door body and the lock through the linkage adjusting function of the adjusting cam 4, without the need for additional customization, significantly reducing the production cost and improving the universality of the product. This has important advantages for mass production and different scene applications.

[0030] Among them, the adjusting end of the rotating adjusting part 3 is set to a shape suitable for common tools, such as a cross-shaped groove, a straight-shaped groove, a plum blossom-shaped groove, a hexagonal protrusion, etc., so that the simple adjusting function not only reduces the difficulty of the installation process, but also improves the convenience of use, which is suitable for ordinary users to install and adjust by themselves in daily environment.

[0031] In some embodiments, at least two long strip-shaped positioning holes 201 are provided on the face cover plate 2 and are respectively located on the upper and lower sides of the rotating adjusting part 3, and are connected with the door frame by a fastener passing through the positioning hole 201. It can be understood that the long strip-shaped positioning hole 201 is arranged along the moving direction of the face cover plate 2, so that when adjustment is needed, the fastener is loosened, the rotating adjusting part 3 is rotated, and the face cover plate 2 can be moved left and right for adjustment, and the sliding cooperation of the fastener and the positioning hole 201 improves the stability of the face cover plate 2 when moving.

[0032] In some embodiments, a pad plate 5 is arranged on the back of the face cover plate 2, and a limiting hole 500 is arranged on the pad plate 5. A limiting block 102 is arranged on the fixing support 1, and the limiting block 102 extends into the limiting hole 500 and is in sliding cooperation with the limiting hole 500, so that a mechanical constraint is formed, and the connection stability between the face cover plate 2 and the fixing support 1 is enhanced. Through the cooperation of the limiting block 102 and the limiting hole 500, the transverse displacement of the face cover plate 2 out of range and the longitudinal displacement of the face cover plate 2 can be effectively prevented when the face cover plate 2 is subjected to external force, so as to ensure the firmness and stability of the entire door buckle plate system.

[0033] Preferably, the limiting block 102 comprises an upper limiting block 1020 and a lower limiting block 1021. The upper limiting block 1020 is in contact with the upper wall of the limiting hole 500, and the lower limiting block 1021 is in contact with the lower wall of the limiting hole 500. The length of the limiting hole 500 is greater than the length of the upper limiting block 1020 and the lower limiting block 1021, so as to form a double limiting structure.

[0034] Further, an opening 103 is arranged between the upper limiting block 1020 and the lower limiting block 1021, and the opening 103 corresponds to the positioning hole 201. The fastener passes through the positioning hole 201 and the opening 103 and is connected with the door frame, so that the installation of the fastener becomes more convenient. The installer can quickly position the fastener, which reduces the installation time and also reduces the installation difficulty.

[0035] In some embodiments, the pad plate 5 and the face cover plate 2 are arranged in one body or in two bodies. Preferably, the pad plate 5 and the face cover plate 2 are two independent parts.

[0036] In some embodiments, the two symmetrical lock holes 200 are arranged on the upper and lower sides of the face cover plate 2 relative to the rotary adjusting member 3. The lock hole 200 can be a rectangular through hole, and the positioning hole 201 is arranged on the side of the lock hole 200 away from the rotary adjusting member 3. The fixing support 1 is located between the two lock holes 200. In this way, the structure of the entire door buckle plate is symmetrical and balanced, and the stress distribution of the face cover plate during installation and use is more uniform, which reduces the structural deformation or wear caused by imbalance.

[0037] Further, the positioning hole 201 is arranged between the lower lock hole 200 and the rotary adjusting member 3, which enhances the stability of the connection between the face cover plate 2 and the door frame.

[0038] In some embodiments, a limiting plate 202 is arranged on the back of the face cover plate 2 on the movement path of the face cover plate 2, so as to form effective limiting, avoid the transverse displacement of the face cover plate 2 out of range, and cooperate with the double limiting structure composed of the limiting block 102 and the limiting hole 500.

[0039] Preferably, the limiting plate 202 is formed by protrusions on the back of the face cover plate 2, and the height of the limiting plate 202 is greater than the thickness of the cushion plate 5. The limiting plate 202 can be formed by bending or milling, and the overall structure is simple.
