Description

Technical Field

[0001] This application relates to the field of door lock installation technology, and more specifically, to a door lock installation structure. Background Technology

[0002] Locks are crucial devices for protecting property and privacy. They typically consist of a lock body and a lock cylinder, which is turned by a key to open and close the door. Locks are secured to doors with screws and mounting holes. In traditional installations, the main fixing screws are located on the interior panel, but the channels for securing these screws (such as the lock cylinder holes) lead to the exterior. This allows attackers to break and remove the exterior lock cylinder, use a specialized long-handled tool to reach inside from the outside, loosen the interior fixing screws, and thus remove the entire lock from the outside.

[0003] Therefore, a door lock installation structure is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a door lock installation structure, including: an inner panel located indoors and an outer panel located outdoors, a door panel disposed between the inner panel and the outer panel, a lock installed inside the door panel, a lock cylinder installed at the lock, elastic retaining plates fixed at both ends of the inner panel, decorative plates connected to the two elastic retaining plates, a through hole opened in the inner panel, an installation groove opened in the inner panel, and an installation hole opened at the end of the door panel near the door frame for connecting the lock.

[0006] Furthermore, the outer end of the door panel is provided with a lock cylinder cavity and a first opening, the lock cylinder cavity through which the lock cylinder passes. The inner end of the outer panel is fixed with two symmetrical anti-disassembly fixing posts. The lock is provided with two symmetrical insertion holes. An embedded plate is inserted into the outer end of the lock cylinder. An insertion post is fixed into the inner end of the embedded plate. A second opening is provided at the insertion post, extending outward and penetrating the embedded plate. The second opening is engaged with the anti-disassembly fixing posts and the threaded fasteners provided inside and outside. A threaded groove is provided at the inner end of the second opening, and the threaded groove is threadedly connected to the threaded fasteners. Both the first opening and the insertion holes are for the insertion post to pass through. A snap-fit ​​groove is provided on the outer periphery of the insertion post, and the snap-fit ​​groove communicates with the second opening.

[0007] Furthermore, the anti-tamper fixing post includes an insert post welded to the outer panel. The outer end of the insert post has a slot, and the inner end face of the insert post has a push groove. The push groove is connected to the slot. A fixing plate is fixed in the slot. An insert block is slidably fitted on the slot. A push block is slidably fitted on the push groove. A push spring is connected between the insert post and the push block. Two sets of tension springs distributed vertically are connected between the insert block and the fixing plate. Each set of tension springs is symmetrically arranged from left to right. The insert block and the push block have inclined surfaces near their respective ends.

[0008] The beneficial effects of this application are as follows: 1. The threaded fastener is threaded into the insert post, thus securing the inner panel and door panel. The anti-tamper fixing post at the inner end of the outer panel is inserted into the insert post. During the connection process between the threaded fastener and the insert post, the anti-tamper fixing post is connected to the insert post, thereby securing the outer panel and door panel. If an outsider forcibly removes the outer panel, the anti-tamper fixing post breaks off at the insert post, thus restricting disassembly by the outsider. Even if an attacker damages the outdoor lock cylinder or even the entire outdoor panel, only the embedded plate on the lock body and the broken anti-tamper fixing post are exposed, preventing any contact with the fixing points from the outside, increasing the difficulty of disassembly by the outsider.

[0009] 2. The lock is installed inside the inner panel through the mounting groove facing inward, so that the inner panel is installed on the indoor surface. The lock is protected by the outer panel and the door panel, which increases the difficulty of disassembly from the outside. The threaded fastener is protected by the decorative panel, which further increases the difficulty of disassembly by people outside. Attached Figure Description

[0021] Reference Figure 1-5 A door lock installation structure includes: an inner panel 10 located indoors and an outer panel 12 located outdoors; a door panel 11 is disposed between the inner panel 10 and the outer panel 12; a lock 13 is installed inside the door panel 11; a lock cylinder 14 is installed at the lock 13; elastic retaining plates 15 are fixed at both ends of the inner panel 10; the two elastic retaining plates 15 have snap-fit ​​grooves at their adjacent ends; decorative panels 16 are elastically snap-fitted onto the two elastic retaining plates 15; a decorative groove 17 is opened on the inner panel 10; the decorative panel 16 is inserted into the decorative groove 17; a through hole is opened on the inner panel 10; a threaded fastener 18 is inserted into the through hole; an installation groove 19 is opened in the inner panel 10; the opening of the installation groove 19 is located near the door frame end and near the inner panel 10 end (e.g., ...). Figure 3As indicated by the two mounting slots 19 in the diagram, the door panel 11 has mounting holes 20 near the door frame end. The mounting holes 20 are used to connect the lock 13, which includes a lock body disposed within the door panel 11 and a fixing plate (such as...) attached to the side of the lock body. Figure 5 As indicated by the two locks 13, the fixing plate and the lock body are fixedly connected by threaded parts. The fixing plate has an opening corresponding to the mounting hole 20, and a threaded part is inserted into the opening and threadedly connected to the mounting hole 20. In the initial state, there is a door panel 11 connected to the door frame. The lock body of the lock 13 part is inserted into the opening of the mounting groove 19 near the end of the inner panel 10, and the fixing plate of the lock 13 part is inserted into the mounting groove 19 near the end of the door frame. After the lock body and the fixing plate are fitted together, the threaded parts are used to fix the lock 13 in place. Then, the inner and outer end faces of the door panel 11 are fitted together. The inner panel 10 and the outer panel 12 are connected by a threaded fastener 18. The inner panel 10 and the outer panel 12 are fixed on the door panel 11. Then, the decorative panel 16 is placed in the decorative groove 17 in the inner panel 10, so that the two elastic plates 15 return to their original position after elastic deformation. The locking groove on the elastic plate 15 abuts against the decorative groove 17 to achieve positioning. Thus, the decorative panel 16 blocks the threaded fastener 18, increasing the difficulty for intruders to unlock the door, thereby maintaining the overall protection effect. The inner panel 10 and the outer panel 12 are made of steel plates with a thickness of 2.0mm or more for protection. The threaded fastener 18 can be fixed with a one-way screw.

[0022] Reference Figure 3-6 The outer end of the door panel 11 (the end closer to the outer panel 12 is the outer end, and the end closer to the inner panel 10 is the inner end) is provided with a lock cylinder cavity 21 and a first opening 22. The lock cylinder cavity 21 is for the lock cylinder 14 to pass through. The inner end of the outer panel 12 is fixed with two symmetrical anti-disassembly fixing posts 23. The lock 13 is provided with two symmetrical insertion holes 24. The outer end of the lock cylinder 14 is inserted into an embedded plate 25. The inner end of the embedded plate 25 is fixed with a post 30. The post 30 is provided with a second opening 32 that is open inside and out. The second opening 32 extends outward and passes through the embedded plate 25. The second opening 32 is inserted and engaged with the anti-disassembly fixing posts 23 and the threaded fastener 18. The inner end of the second opening 32 is provided with a threaded groove, which is threadedly connected to the threaded fastener 18. The first opening 22 and the insertion hole 24 are both for the post 30 to pass through. The outer periphery of the post 30 is provided with a snap-fit ​​groove 31, which is connected to the second opening 32. After the lock 13 is fixedly connected to the inner panel 10, the lock 13 is inserted into the door panel 11 through the lock cylinder cavity 21. The middle part of the lock 13 is located inside the lock 13 to control the operation of the internal components of the lock 13, thereby realizing the movement of the side limit post of the lock 13 and realizing the locking and unlocking function. The embedded plate 25 is inserted into the cylinder of the lock cylinder 14, so that the insertion post 30 fixedly connected to the rear end of the embedded plate 25 is inserted into the inner panel 10 through the insertion hole 24 and passes through the first opening 22. Then, the inner panel 10 and the outer panel 12 are abutted against the inner end face of the door panel 11. The plate 10 is initially positioned by the insertion of the through hole and the insertion post 30. The outer panel 12 is initially positioned by inserting the anti-disassembly fixing post 23 welded to the inner end into the insertion post 30. Then, the threaded fastener 18 is inserted through the through hole of the inner panel 10. The threaded fastener 18 is screwed into the second opening 32 by a tool, so that the threaded fastener 18 is connected with the thread groove of the second opening 32. As the threaded fastener 18 is screwed in, the nut of the threaded fastener 18 abuts against the inner panel 10, thereby pushing the inner panel 10 closer to the door panel 11, thus fixing the inner panel 10 to the door panel 11. When an intruder forcibly removes the outer panel 12, the welding mechanism can cause the anti-tamper fixing post 23 to break inside the insert post 30 after the outer panel 12 is shattered and removed, thereby dividing the outer end opening of the second opening 32 and forming a blind hole at the second opening 32. This prevents the intruder from finding or contacting the head of the threaded fastener 18 from the outside, and therefore prevents them from loosening the screws. The welding strength between the outer panel 12 and the anti-tamper fixing post 23 is lower than the abutment structure strength between the insert block 41, the insert post 30 and the insert post 40.

[0023] Reference Figure 7-10 The anti-disassembly fixing post 23 includes an insertion post 40 welded to the outer panel 12. A slot 46 is provided on the outer end of the insertion post 40, and a push groove 45 is provided on the inner end face of the insertion post 40. The push groove 45 is connected to the slot 46. A fixing plate 47 is fixedly installed in the slot 46. An insertion block 41 is slidably fitted on the slot 46, and a push block 42 is slidably fitted on the push groove 45. A push spring 43 is connected between the insertion post 40 and the push block 42. Two sets of tension springs 44 are distributed vertically between the insertion block 41 and the fixing plate 47. Each set of tension springs 44 is symmetrically arranged from left to right. An inclined surface is provided near the end of both the insertion block 41 and the push block 42. As the threaded fastener 18 is screwed into the second opening 32, it abuts against the push block 42 (during which the outer panel 12 is manually pushed towards the door panel 11 to align the opening of the slot 46 with the opening of the snap-fit ​​groove 31). In the subsequent process, the push block 42 is pushed outward, causing the inclined surface on the push block 42 to abut against the inclined surfaces on the two insert blocks 41. This pushes the two insert blocks 41 outward against the spring force of the tension spring 44, causing the insert blocks 41 to extend outward from the inner end of the slot 46 and thus insert into the side wall of the snap-fit ​​groove 31. Figure 8 As shown, after the inner panel 10 is tightly attached to the door panel 11, a reverse force is applied to the outer panel 12 (a tension force is applied to the outer panel 12, and the tension force is provided by the threaded fastener 18 to the insert post 30, and the insert post 30 is provided to the insert post 40 through the insert block 41), thereby fixing the outer panel 12 and the door panel 11 together.
