Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock body technology, specifically a split door lock panel. Background Technology
[0002] A split-panel lock typically refers to a lock design where the outer and inner panels can be independently removed or adjusted, commonly found in smart locks, lever handle locks, or mortise locks. This design facilitates installation, maintenance, or adjustment of the opening direction.
[0003] The existing lock body is installed on the door panel by screws. The door panel needs to be drilled with holes corresponding to the lock, which makes it easy for the separate lock plate to become mismatched during use. This leads to difficulties in the installation process, making it difficult to adapt the lock to door panels of different sizes. As a result, the lock's applicability is limited, installation efficiency is affected, and the practicality of the lock is reduced. This needs to be optimized and improved. Utility Model Content

Detailed Implementation
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0024] like Figure 1 - Figure 4 As shown, this application provides a split lock door panel, including: a bonding plate 1, a positioning plate 2 is provided on the outer side of the bonding plate 1, and a lock cylinder through hole 3 is connected to the inner side of the positioning plate 2. The lock cylinder through hole 3 is used for positioning in the middle and for center alignment of the door lock installation.
[0025] Specifically, such as Figure 1 As shown, both ends of the inner side of the positioning plate 2 are provided with external positioning holes 4. The external positioning holes 4 are used for installation positioning on the outside of the door panel. The inner side of the positioning plate 2 is fixedly connected with a limit block 5. The limit block 5 is used for limiting and locking the positioning plate 2 during installation.
[0026] The positioning plate 2 is provided with a positioning adjustment component on its inner side. The positioning adjustment component includes an internal mounting block 10. The bottom end of the internal mounting block 10 is connected to an internal positioning screw hole 14, and the top end of the internal mounting block 10 is rotatably connected to a rotating connecting block 12. The positioning adjustment component is used for adjustment when installing the split lock door panel.
[0027] Specifically, such as Figure 2 As shown, the built-in mounting block 10 is fixedly connected to the bottom of the positioning plate 2. There are four built-in mounting blocks 10. The installation is improved by connecting the four built-in mounting blocks 10.
[0028] Specifically, such as Figure 4 As shown, an adjusting slider 13 is slidably connected to the inner side of the built-in mounting block 10. The inside of the built-in mounting block 10 is provided with a sliding groove 11 that is slidably connected to the adjusting slider 13. The adjusting slider 13 slides inside the sliding groove 11 for adjusting the installation position.
[0029] Specifically, such as Figure 4 As shown, the inner positioning screw hole 14 is located inside the adjusting slider 13, and the bottom end of the adjusting slider 13 is connected to a rubber pad 15. The adjustment of the adjusting slider 13 is used for installation and positioning of the inner positioning screw hole 14. The rubber pad 15 on the inner side is to improve the elastic compression of the adjusting slider 13 after sliding, so as to achieve a certain positional static effect.
[0030] The outer side of the bonding plate 1 is provided with a pressure-resistant mounting component, which includes an arc-shaped edge 6 and an arc-shaped edge 8 at the top of the arc-shaped edge 6. The pressure-resistant mounting component is used for locking when the split lock door panel is installed.
[0031] Specifically, such as Figure 3 As shown, the arc-shaped edge 6 is fixedly connected to the outside of the bonding plate 1, and the top of the arc-shaped edge 6 is integrally connected to the prism edge 7. The arc-shaped edge 6 is set in the middle of the bonding plate 1 and the prism edge 7 for support connection, which facilitates the bonding and diffusion of pressure when pressing.
[0032] Specifically, such as Figure 3 As shown, the second arc edge 8 is connected to the top of the first prism edge 7, and the top of the second arc edge 8 is integrally connected to the second prism edge 9. The first prism edge 7 and the positioning plate 2 are supported by the second arc edge 8. The arc design prevents the pressure from concentrating at one point during compression, thus improving the installation buffer protection effect.
[0033] In this embodiment: during the installation of the split lock door panel, an outer positioning hole 4 is provided on the outer side for connection and installation, and then four rotatable and adjustable built-in mounting blocks 10 are provided on the inner side for orientation adjustment. Then, an adjustable slider 13 with slidable position adjustment is provided on the inner side of the built-in mounting block 10 to adapt to the installation of different doors. A certain gap is provided between the bonding plate 1 and the positioning plate 2. Then, an arc-shaped edge 6, a rhombus-shaped edge 7, an arc-shaped edge 8, and a rhombus-shaped edge 9 are provided on the outer side to form an arc-shaped surface and a right-angle surface, so that the door panel can pass through multiple stepped outer protections during installation, thereby improving the stability of the installation.
[0034] The specific solution is as follows: When installing the split lock door panel, first, two inner and outer bonding plates 1 are fitted to the door and aligned. Then, they can be connected and installed through the outer positioning hole 4 on the outside. Alternatively, internal installation adjustments can be made by adjusting the rotation position through the built-in mounting block 10 connected to the bottom rotating connecting block 12. Then, the slider 13 is adjusted to slide in the groove 11 on the inner side of the built-in mounting block 10, so that the position of the inner positioning screw hole 14 can be adjusted and installed within a certain range. Then, the lock cylinder is passed through the lock cylinder through hole 3 to install the entire lock body. Between the bonding plate 1 and the positioning plate 2, arc-shaped edge 1 6, rhombus-shaped edge 1 7, arc-shaped edge 2 8, and rhombus-shaped edge 2 9 are set, with arc-shaped edges and right-angle edges alternately set. This not only increases the appearance of the door panel but also increases the external pressure resistance during installation. The arc-shaped edges can distribute pressure in layers, allowing the door panel to pass through multiple stepped external protections during installation, improving the stability of the installation.
[0035] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
[0036] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
