[0016] The present invention will be further described in detail below with reference to the accompanying drawings, wherein the same parts are represented by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific part, respectively.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Design concept: Design an auxiliary door lock installation tool with adjustable drilling and keyhole position, suitable for different locks or door panel thicknesses.

[0019] Example: like Figure 1 - Figure 3As shown, this embodiment provides a device for installing a door lock, including a bracket 1, which is an L-shaped bracket 1 composed of a long section 11 and a short section 12. Further, it also includes a large adjusting plate 2 and a small adjusting plate 3. The large adjusting plate 2 is slidably connected along the long section 11, and the small adjusting plate 3 is slidably connected along the short section 12. Both the large adjusting plate 2 and the small adjusting plate 3 are provided with guide holes 4 for installing the door lock, and guide rings 41 are provided around the guide holes 4. Further, the large adjusting plate 2 and the small adjusting plate 3 are rectangular, the guide holes 4 are circular, and the bracket 1, the large adjusting plate 2, and the small adjusting plate 3 are all made of plastic.

[0020] In this embodiment, the bracket 1 is the main structure, serving as the overall support and reference; it is L-shaped, with one side longer (long segment 11) and the other side shorter (short segment 12). Each side has symmetrical screw holes for installing two hexagonal ball set screws 7 for positioning, which are used to adjust the positions of the large adjusting plate 2 and the small adjusting plate 3 respectively.

[0021] To limit the sliding distance of the large adjusting plate 2 and the small adjusting plate 3, a baffle 5 and a screw 6 are also included. The sliding limit ends of the long section 11 and the short section 12 are respectively provided with baffles 5, and are fixed to the bracket 1 by screws 6. The baffle 5 is an auxiliary component of this product, which serves to fix and limit the position of the large adjusting plate 2 and the small adjusting plate 3, and prevent them from falling off when adjusting the position; it is shaped like a cuboid with protrusions and two screw holes.

[0022] In this embodiment, to position the sliding positions of the large adjusting plate 2 and the small adjusting plate 3, the bracket 1 is symmetrically equipped with hexagonal socket head cap screws 7 on both sides. The large adjusting plate 2 and the small adjusting plate 3 are each provided with two corresponding adjustment grooves 8. The hexagonal socket head cap screws 7 position the large adjusting plate 2 and the small adjusting plate 3 through the adjustment grooves 8. More specifically, the hexagonal socket head cap screws 7 function to spring up the steel ball and adjust the position of the recessed holes in the large adjusting plate 2 and the small adjusting plate 3, preventing the large and small adjusting plates 3 from falling off during use. The hexagonal socket head cap screws 7 are cylindrical in shape with protrusions, springs, and threads.

[0023] The large adjustment plate 2 in this embodiment is a key component of the door lock assembly, serving to adjust the position of the main panel and the drilling direction of the guide saw when drilling the lock hole. It is shaped like a cuboid with a raised center and a circular core, and has two concave positioning grooves drilled on each of its two sides to adjust the position of the central circular hole (main positioning hole 14) relative to the bracket 1, thereby achieving drilling positioning for different lock hole positions. The small adjusting plate 3 in this embodiment is also a key component of the door lock assembly, serving to adjust the position of the side panel and the drilling direction of the guide saw when drilling the lock hole. It is shaped like a cuboid with a raised center and a circular core. Two concave positioning grooves are drilled on each of the two sides to adjust the position of the central circular hole (side positioning hole 31) relative to the bracket 1, thereby achieving drilling positioning of the lock hole position for door panels of different thicknesses. The small adjusting plate 3 also has two side positioning holes 31 at a vertical distance of 42mm from the circular hole. These are used to drill two circular holes first during the initial lock hole positioning, and then use door lock screws to fix the entire door lock assembly (bracket 1) to the door panel.

[0024] To save materials and reduce weight, the corner of the bracket 1 is provided with a groove 13.

[0025] For easier fixing and installation, two main positioning holes 14 are symmetrically provided at the long section 11 of the bracket 1, and two side positioning holes 31 are symmetrically provided on the small adjustment plate 3.

[0026] In this embodiment, the bracket 1 is provided with a sliding groove 15 on the inner side, and the large adjustment plate 2 and the small adjustment plate 3 are displaced along the sliding groove 15.

[0027] Explanation of the principle: When installing a door lock, loosen the hexagonal set screw 7, slide the large adjusting plate 2 and the small adjusting plate 3 to the desired position, aligning the guide ring 41 with the preset lock body and bolt holes on the door panel. The hexagonal set screw 7 is then engaged in the adjusting groove 8 for positioning. The device is fixed to the door panel using the bracket 1, with the main positioning hole 14 and the side positioning hole 31 positioning the drilling position. Drilling is then performed using the guide ring 41 as a reference. Because the bracket 1 uses an L-shaped structure and is equipped with adjustable plates, it can adapt to the installation requirements of different lock specifications, especially suitable for various door thicknesses and lock body sizes, improving installation accuracy and efficiency. By adjusting the relative positions of the large adjusting plate 2 and the small adjusting plate 3, the installation distance between the lock body and bolt can be precisely matched, adapting to different door thicknesses and lock specifications, ensuring rapid positioning and stable support in different installation environments. The design of the guide ring 41 effectively guides the drill bit along a preset trajectory, reducing offset errors and improving hole machining accuracy. The entire device is compact and easy to operate, requiring no professional skills to complete the precise installation of the door lock, significantly reducing construction difficulty and time costs.

[0028] Specific practices: Practical application tests by workers show that the device is adaptable to various door panels with thicknesses ranging from 35mm to 60mm, compatible with mainstream lock models on the market, and has good promotional value and practicality. Test data shows that the adjustment accuracy can reach ±0.5mm, and the one-time drilling success rate exceeds 98%. On-site operators reported that a single person can complete the door lock positioning and drilling guidance work, reducing the average installation time to less than 15 minutes, an efficiency improvement of about 70% compared to traditional methods. When the device is reused, there is no significant wear on the components, and the positioning stability is good, meeting the needs of batch construction. Field tests also show that operators only need simple training to master the device adjustment and positioning process, significantly reducing reliance on highly skilled workers.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
