Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to a glass door lock cover. Background Technology

[0002] Currently, glass door locks installed on glass doors typically have a lock cover installed on the outside of the lock body to make the glass door more aesthetically pleasing. In traditional structures, the lock cover consists of a front cover and a rear cover, with the lock body housed inside the lock cover. The portion of the glass door corresponding to the lock is sandwiched between the front and rear covers. The installation structure of the lock cover and lock body can be implemented in two ways:

[0003] 1. One method involves first installing the lock body onto the glass door frame. During installation, two aluminum plates are inserted into their corresponding inner grooves on the door frame. Then, screws are used to tighten the lock body's outer liner, the aluminum plates, and the door frame, connecting the lock body to the door frame. Next, the front and rear covers of the lock cover are placed on the front and rear sides of the lock body, respectively. The lock base is then placed on both sides of the lock cover and connected to the lock body, completing the assembly of the lock cover and lock body. However, this assembly method is very cumbersome, and a large gap will always exist between the lock cover and the door frame, affecting the overall aesthetics.

[0004] 2. Another method is to integrate the front and back covers of the lock cover. The lock cover is hollow with an opening at one end for the lock body to pass through. During installation, the lock cover is simply placed over the lock body and then fastened to the door frame. This installation method solves the problems of the first method. However, it also has new drawbacks. Since the installed glass thickness is fixed (generally 8mm), any changes to the glass thickness require re-manufacturing according to the corresponding glass specifications. Furthermore, this structure is difficult and costly to manufacture.

[0005] Therefore, it is essential to improve the existing glass door lock covers to address the aforementioned issues. Utility Model Content

[0032] 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.

[0033] Example: As attached Figures 1-4 The glass door lock cover shown is installed on the door frame to cover the lock body inside. It includes a front cover 1 and a rear cover 2, with an installation gap 3 formed between the front cover 1 and the rear cover 2 for the glass door to pass through. It also includes at least one set of locking components 4. In this embodiment, two sets of locking components 4 are used. The locking components 4 include a driving member 5 and a follower member 6. The driving member 5 and the follower member 6 are linked together and can move closer to each other or further away from each other. The driving member 5 is disposed on the door frame, and the follower member 6 is connected to the front cover 1 and the rear cover 2. When the driving member 5 drives the follower member 6 to move, the follower member 6 presses the front cover 1 and the rear cover 2 tightly against the door frame. During installation, the front cover 1 and rear cover 2 are wrapped around the lock body. The follower 6 is connected to the front cover 1 and rear cover 2. The drive unit 5, which is located on the door frame, is operated to cause the follower 6 to move the front cover 1 and rear cover 2 towards the door frame until they are pressed tightly against the door frame without any large gaps. This design is not only very convenient to install, but also adaptable to different glass thicknesses. The distance between the front cover 1 and rear cover 2 can be adjusted according to the glass thickness. Furthermore, after installation, it fits snugly against the door frame, ensuring a good aesthetic appearance.

[0034] As attached Figures 1-4 As shown, the driving component 5 includes a screw 7, and the follower component 6 has a threaded hole 8 that mates with the screw 7, meaning the two are connected by a thread. Using the screw 7 as the driving component 5 is convenient because the component is readily available and inexpensive. An opening in the door frame allows the screw shank to pass through, but not the head of the screw 7. The screw 7 mates with the threaded hole 8 on the follower component 6, allowing the screw 7 to rotate and drive the follower component 6 to move linearly. The structure is simple and reliable, facilitating production and assembly.

[0035] As attached Figure 2 As shown, the follower 6 has a protrusion 9 on each side, symmetrically arranged on the front and rear sides of the follower 6. The front cover 1 and the rear cover 2 are respectively provided with grooves 10 for cooperating with the protrusions 9. Similarly, the positions of the protrusions 9 and the grooves 10 can be interchanged. The front cover 1 and the rear cover 2 are connected to the follower 6 through a convex-concave fit, so that the follower 6 can drive the front cover 1 and the rear cover 2 to move together and finally press against the door frame. The connection structure is simple and reliable, and the manufacturing process is very convenient.

[0036] As attached Figure 3 and attached Figure 4 As shown, the follower 6 includes a follower block 11 and a reinforcing block 12. The reinforcing block 12 is mounted on the follower block 11. The follower block 11 has a through hole 13 for the screw 7 to pass through. The screw hole 8 is disposed on the reinforcing block 12, and the screw hole 8 and the through hole 13 are coaxially arranged. In this embodiment, both ends of the reinforcing block 12 also extend into the corresponding groove portion 10. The follower 6 adopts a combination of the follower block 11 and the reinforcing block 12, which has the advantages of convenient processing and high structural strength.

[0037] As a preferred embodiment, in this case, the follower block 11 is made of plastic, and the reinforcing block 12 is made of metal. The plastic follower block 11 allows for the production of different shapes through injection molding, making processing very convenient. Combined with the metal reinforcing block 12, the overall strength of the follower component 6 is ensured, and its service life is improved. Alternatively, the follower block 11 and reinforcing block 12 can also be made of other materials as needed.

[0038] As attached Figure 3 and attached Figure 4 As shown, the follower block 11 has a positioning groove 14 at the end away from the driving component 5, and the reinforcing block 12 is embedded in the positioning groove 14. The reinforcing block 12 is embedded in the positioning groove 14 of the follower block 11, realizing the assembly of the two, and the assembly operation is very convenient.

[0039] As a preferred embodiment, the positioning groove 14 can be configured in a manner that is not specified. Figure 3 and attached Figure 4 As shown: The follower block 11 is provided with multiple positioning blocks 15 that abut against the periphery of the reinforcing block 12. The positioning blocks 15 and the follower block 11 are an integral structure. The reinforcing block 12 is rectangular in shape, and there are four positioning blocks 15 abutting against the four sides of the reinforcing block 12. The area of ​​the follower block 11 corresponding to the four positioning blocks 15 forms the positioning groove 14. Using multiple positioning blocks 15 to position the reinforcing block 12 can reduce the machining accuracy requirements of the reinforcing block 12 and the positioning blocks 15. Even if the size of the reinforcing block 12 is slightly larger than the size of the positioning groove 14, the positioning blocks 15 can be slightly deformed to allow the reinforcing block 12 to be embedded in the positioning groove 14, thus facilitating production.

[0040] As attached Figure 3 and attached Figure 4 As shown, the follower block 11 has at least one positioning protrusion 16 at the end away from the driving member 5, and the reinforcing block 12 has a positioning hole 17 that matches the positioning protrusion 16. This design can further improve the stability of the connection structure between the follower block 11 and the reinforcing block 12.

[0041] As attached Figure 3 and attached Figure 4 As shown, the positioning protrusion 16 includes a plurality of annular protrusions 18 arranged in a circumferential array. The outer diameter of the combined structure of the plurality of annular protrusions 18 is not less than the diameter of the inner diameter of the positioning hole 17. The outer diameter of the annular protrusion 18 is interference-fitted with the inner diameter of the positioning hole 17. The elastic force generated by the deformation of the annular protrusion 18 presses against the inner wall of the positioning hole 17, which facilitates the installation of the reinforcing block 12 and also improves the stability of the connection structure between the reinforcing block 12 and the follower block 11.

[0042] As attached Figure 3 and attached Figure 4 As shown, the follower 6 has a limiting protrusion 19 at one end near the drive member 5 for embedding into the vertical groove of the door frame. The limiting protrusion 19 of the follower 6 is embedded into the vertical groove of the door frame, which is a standard design on existing door frames for embedding glass edges. Limiting the follower 6 not only ensures the installation accuracy of the door lock cover but also improves the stability of the door lock cover installation.
