Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock cover technology, and in particular to a highly adaptable lock cover assembly. Background Technology
[0002] The lock cylinder of a door lock is usually installed directly into the keyhole on the door. In order to ensure that the lock cylinder can be well fixed in the keyhole and to maximize the service life of the lock cylinder, the existing technology uses a lock cover to fix and protect it.
[0003] Existing lock covers consist of a single integrated design, with the lock cylinder cover embedded within the door to secure the lock cylinder, and the protective cover protruding outwards to cover and protect both the lock cylinder and the door cylinder. However, because the lock cylinder cover and protective cover are integrated, they must be made of the same material, making it difficult to match with the door and resulting in an unsightly appearance. Replacement is also inconvenient, requiring the entire cover to be replaced. Furthermore, due to the integrated design, the safety knob can only be installed on the outermost protective cover, causing it to protrude and become susceptible to scratches and damage. Summary of the Invention

The magnetic iron plate is fixedly installed on the second mounting groove by passing through the second connecting through hole with screws and connecting to the second fixing threaded hole.
[0012] As described above, a highly adaptable lock cover assembly includes a safety knob structure that rotates on the lock cylinder cover and a knob groove formed on the protective cover to expose the safety knob.
[0013] As described above, a highly adaptable lock cover assembly has a slot at the outer end of the peripheral sidewall of the lock cylinder cover. After the protective cover is installed and embedded in the slot, the outer surface of the protective cover is flush with the outer end of the peripheral sidewall of the lock cylinder cover.
[0014] As described above, a highly adaptable lock cover assembly is provided with several mounting holes on the lock cylinder cover.
[0015] As described above, a highly adaptable lock cover assembly is provided, wherein the lock cylinder cover is further provided with a lock cylinder hole.

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0024] Please see Figures 1 to 5 As shown, this application embodiment provides a highly adaptable lock cover assembly, including a lock cylinder cover 1 embedded in the door panel, a protective cover 2, and a disassembly and assembly structure 3 and a safety knob structure 4 disposed between the lock cylinder cover 1 and the protective cover 2, wherein the protective cover 2 is installed and embedded in the lock cylinder cover 1 through the disassembly and assembly structure 3.
[0025] By separately setting the lock cylinder cover 1 and the protective cover 2, during installation, the lock cylinder cover 1 is first embedded in the door panel to fix the lock cylinder, and then the appropriate protective cover 2 is selected according to the specific situation of the door (such as a wooden protective cover for wooden doors, a steel protective cover for steel doors, etc.). Then, the protective cover 2 is installed and embedded into the lock cylinder cover 1 through the disassembly and assembly structure 3 to complete the assembly. It is practical and convenient, and can be freely assembled according to the specific situation of the door. It has wide applicability and high adaptability, and also makes the overall assembly of the door and the protective cover assembly more beautiful.
[0026] Furthermore, the disassembly and assembly structure 3 includes a first magnetic attraction part 31 disposed on the lock cylinder cover 1, and a second magnetic attraction part 32 disposed on the protective cover 2 and capable of magnetically attracting the first magnetic attraction part 31.
[0027] Specifically, the first magnetic attraction part 31 includes a plurality of first mounting grooves 311 provided on the lock cylinder cover 1, and a strong magnetic block 312 installed in the first mounting grooves 311.
[0028] The second magnetic suction part 32 includes a second mounting groove 321 provided on the protective cover 2 and a magnetic suction plate 322 installed in the second mounting groove 321.
[0029] During assembly, after the lock cylinder cover 1 is embedded in the door panel to fix the lock cylinder, the selected protective cover 2 is placed in front of the lock cylinder cover 1 and moved towards the lock cylinder cover 1 to fit together. Then, the magnetic attraction between the strong magnetic block 312 and the magnetic iron plate 322 is used to complete the fixation, which is practical and convenient.
[0030] In this embodiment, a first fixing threaded hole 313 is also provided at the bottom of the first mounting groove 311, and a first connecting through hole 314 is provided on the strong magnetic block 312. The strong magnetic block 312 is fixedly installed on the first mounting groove 311 by passing a screw through the first connecting through hole 314 and connecting it to the first fixing threaded hole 313. This facilitates assembly.
[0031] The bottom of the second mounting groove 321 is also provided with a plurality of second fixing threaded holes 323, and the magnetic plate 322 is provided with a second connecting through hole 324. The magnetic plate 322 is fixedly installed on the second mounting groove 321 by screws passing through the second connecting through hole 324 and connecting to the second fixing threaded hole 323. This facilitates assembly.
[0032] Furthermore, the safety knob structure 4 includes a safety knob 41 that is rotatably mounted on the lock cylinder cover 1, and a knob groove 42 that is opened on the protective cover 2 and allows the safety knob 41 to be exposed.
[0033] By placing the safety knob 41 on the lock cylinder cover 1 and then setting the knob groove 42 on the protective cover 2, most of the safety knob 41 can be placed inside the protective cover assembly, greatly reducing the outward protrusion of the protective cover assembly, protecting the safety knob 41, and making the overall appearance more aesthetically pleasing.
[0034] Furthermore, a slot 10 is provided at the outer end of the side wall of the lock cylinder cover 1. After the protective cover 2 is installed and embedded in the slot 10, the outer surface of the protective cover 2 is flush with the outer end of the side wall of the lock cylinder cover 1. This makes the overall appearance neater and more aesthetically pleasing.
[0035] Furthermore, the lock cylinder cover 1 is also provided with several mounting holes 5.
[0036] Furthermore, the lock cylinder cover 1 is also provided with a lock cylinder hole 6.
[0037] In summary, this embodiment of the application separates the lock cylinder cover 1 and the protective cover 2. During installation, the lock cylinder cover 1 is first embedded in the door panel to fix the lock cylinder. Then, a suitable protective cover 2 is selected according to the specific situation of the door (e.g., a wooden protective cover can be selected for wooden doors, and a steel protective cover can be selected for steel doors, etc.). The protective cover 2 is then installed and embedded into the lock cylinder cover 1 through the disassembly and assembly structure 3 to complete the assembly. It is practical and convenient, and can be freely assembled according to the specific situation of the door. It has wide applicability and high adaptability, and also makes the overall assembly of the door and the protective cover assembly more aesthetically pleasing.
[0038] Furthermore, by placing the safety knob 41 on the lock cylinder cover 1 and then setting the knob groove 42 on the protective cover 2, most of the safety knob 41 can be placed inside the protective cover assembly, greatly reducing the outward protrusion of the protective cover assembly, protecting the safety knob 41, and making the overall appearance more aesthetically pleasing.
[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
