Description
Technical Field
[0001] The utility model relates to the technical field of locks, in particular to a quick disassembly and assembly structure for locks. Background Art
[0002] Locks such as door locks generally include an outer ring cover and an inner lining block. The two are fixedly combined to form the outer shell of the lock, and components such as a lock core are installed inside the lining block.
[0003] Among them, the connection between the ring cover and the lining block is usually a threaded connection, that is, an internal thread is opened on the inner side of the ring cover, an external thread is opened on the outer side of the lining block, and then the lining block is screwed into the ring cover to make the internal thread mesh with the external thread, realizing the connection between the ring cover and the lining block.
[0004] However, the above-mentioned threaded connection method between the ring cover and the lining block has the following defects. During production, it is necessary to open an internal thread on the inner side of the ring cover and an external thread on the outer side of the lining block, resulting in high processing costs and low processing efficiency; during assembly, it is also necessary to gradually screw the lining block into the ring cover, with a slow assembly speed and high labor costs. Summary of the Invention
[0005] Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to propose a quick disassembly and assembly structure for locks, which is used to solve problems such as high processing costs and assembly costs of the lining block and the ring cover in the existing locks.
[0006] The technical solution adopted by the utility model to solve its technical problems is a quick disassembly and assembly structure for locks, including:
[0007] A ring cover and a lining block inside the ring cover, with a plurality of protrusions provided on either of the two, and a plurality of installation grooves provided on the other of the two;
[0008] Among them, the installation groove includes a first groove section and a second groove section that communicate with each other. The protrusion can slide from the first groove section into the second groove section. The length direction of the first groove section is arranged along the axial direction of the ring cover / the lining block, and the length direction of the second groove section is arranged along the circumferential direction of the ring cover / the lining block.
[0009] Further, a plurality of the protrusions are provided on the inner side wall of the ring cover, and a plurality of the installation grooves are opened on the outer side wall of the lining block.
[0010] Further, a plurality of the installation grooves are opened on the inner side wall of the ring cover, and a plurality of the protrusions are provided on the outer side wall of the lining block.
[0011] Further, a plurality of elastic members are provided between the ring cover and the lining block. The elastic members are simultaneously connected to a first connecting portion on the ring cover and a second connecting portion on the lining block, and the elastic members are used to provide a pre-tightening force for making the first connecting portion and the second connecting portion approach or move away from each other.
[0012] Further, the elastic member is a spring, and one end of the spring abuts against the inner side wall of the ring cover, and the other end abuts against the outer side wall of the lining block.
[0013] Further, the elastic member is an elastic sheet, and an abutting portion is provided in the middle of the elastic sheet;
[0014] The outer side wall of the lining block is recessed inward to form a plurality of installation notches. The elastic sheet is placed in the installation notches, and the abutting portion can abut against the inner side wall of the ring cover.
[0015] Further, the depth of the second groove section gradually decreases in a direction away from the first groove section, so that at least part of the second groove section can be in interference fit with the protrusion.
[0016] Further, the lining block has a first end and a second end that are opposite ends. One end of the first groove section away from the second groove section is connected to the first end, and the protrusion can slide into the first groove section from the first end.
[0017] Further, the second groove section is connected to the second end, and the surface of the protrusion is flush with the end surface of the second end.
[0018] Compared with the prior art, the present utility model has at least the following beneficial effects:
[0019] A protrusion is provided on either the lining block or the ring cover, and an installation groove is provided on the other. Since the first groove section is arranged axially, when the lining block moves axially relative to the ring cover, the protrusion can slide axially into the first groove section; since the second groove section is arranged circumferentially, when the lining block rotates relative to the ring cover, the protrusion can be driven to slide into the second groove section. At this time, the protrusion and the second groove section cooperate with each other to realize the rapid installation of the lining block and the ring cover. In this way, the original scheme of connecting by threads is replaced, the processing cost and the assembly cost are reduced, and the production efficiency is improved. Description of the Drawings

[0028] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0029] Please refer to Figures 1-4 , the present invention discloses a quick disassembly and assembly structure for a lock, including:
[0030] A ring cover 100 and a lining block 200 inside the ring cover 100, and a plurality of protrusions 110 are provided on any one of the two, and a plurality of installation grooves 210 are provided on the other of the two;
[0031] Wherein, the installation groove 210 includes a first groove section 211 and a second groove section 212 that communicate with each other, the protrusion 110 can slide from the first groove section 211 into the second groove section 212, the length direction of the first groove section 211 is arranged along the axial direction of the ring cover 100 / the lining block 200, and the length direction of the second groove section 212 is arranged along the circumferential direction of the ring cover 100 / the lining block 200.
[0032] Specifically, in this application, protrusions 110 are provided on any one of the lining block 200 and the ring cover 100, and installation grooves 210 are provided on the other. Since the first groove section 211 is arranged axially, when the lining block 200 moves axially relative to the ring cover 100, the protrusion 110 can slide axially into the first groove section 211; since the second groove section 212 is arranged circumferentially, when the lining block 200 rotates relative to the ring cover 100, the protrusion 110 can be driven to slide into the second groove section 212. At this time, the protrusion 110 cooperates with the second groove section 212 to realize the quick installation of the lining block 200 and the ring cover 100. In this way, the original scheme of connecting by threads is replaced, reducing the processing cost and assembly cost and improving the production efficiency.
[0033] Furthermore, a plurality of the protrusions 110 are provided on the inner side wall of the ring cover 100, and a plurality of the installation grooves 210 are formed on the outer side wall of the lining block 200.
[0034] Further, a plurality of the mounting grooves 210 are formed on the inner sidewall of the ring cover 100, and a plurality of the protrusions 110 are provided on the outer sidewall of the lining block 200.
[0035] Specifically, in this application, a plurality of protrusions 110 can be arranged on the inner side of the ring cover 100, and at the same time, a plurality of mounting grooves 210 can be arranged on the outer side of the lining block 200. Alternatively, a plurality of protrusions 110 can be arranged on the outer side of the lining block 200, and at the same time, a plurality of mounting grooves 210 can be arranged on the inner side of the ring cover 100.
[0036] Further, a plurality of elastic members 300 are provided between the ring cover 100 and the lining block 200. The elastic members 300 are simultaneously connected to a first connecting portion on the ring cover 100 and a second connecting portion on the lining block 200. The elastic members 300 are used to provide a pre-tightening force for making the first connecting portion and the second connecting portion approach or move away from each other.
[0037] Specifically, a plurality of elastic members 300 are simultaneously arranged between the ring cover 100 and the lining block 200, so that the lining block 200 is subjected to extrusion forces or tensile forces from different directions. Thereby, the lining block 200 can be restricted within the ring cover 100, preventing the protrusions 110 from slipping out of the second groove section 212 due to the relative rotation of the lining block 200 with respect to the ring cover 100, and avoiding the separation of the lining block 200 from the ring cover 100. In this way, the bonding strength between the lining block 200 and the ring cover 100 can be improved.
[0038] Further, the elastic member 300 is a spring, and one end of the spring abuts against the inner sidewall of the ring cover 100, and the other end abuts against the outer sidewall of the lining block 200.
[0039] Specifically, setting the elastic member 300 as a helical spring or a torsion spring can also apply an extrusion force or a tensile force to the lining block 200 and the ring cover 100 to enhance the bonding strength between the lining block 200 and the ring cover 100.
[0040] Further, the elastic member 300 is an elastic sheet, and a contact portion 310 is provided in the middle of the elastic sheet;
[0041] The outer sidewall of the lining block 200 is recessed inward to form a plurality of mounting notches. The elastic sheet is placed in the mounting notches, and the contact portion 310 can abut against the inner sidewall of the ring cover 100.
[0042] Specifically, both ends of the elastic sheet extend into the mounting notches at the same time. The contact portion 310 in the middle of the elastic sheet protrudes from the peripheral wall of the lining block 200 and abuts against the inner sidewall of the ring cover 100. In this way, a plurality of elastic sheets simultaneously apply extrusion forces in different directions to the lining block 200 and the ring cover 100, thereby preventing the relative rotation of the lining block 200 and the ring cover 100 and improving the bonding strength between the two.
[0043] Furthermore, the depth of the second groove section 212 gradually decreases in a direction away from the first groove section 211 , so that at least a portion of the second groove section 212 can be interference-fitted with the protrusion 110 .
[0044] Specifically, the present application can also prevent the protrusion 110 from sliding out of the second groove section 212 through the interference fit between the second groove section 212 and the protrusion 110, thereby improving the bonding strength between the lining block 200 and the ring cover 100.
[0045] Among them, as the protrusion 110 gradually slides into the second groove section 212, the protrusion 110 is first separated (clearance fit) or contacts (transition fit) from the bottom of the second groove section 212. As the protrusion 110 further slides into the second groove section 212, the protrusion 110 and the bottom surface of the second groove section 212 are squeezed against each other, and the squeezing force gradually increases with the sliding depth of the protrusion 110, so as to achieve an interference fit between the protrusion 110 and the second groove section 212, thereby ensuring that the protrusion 110 will not unnaturally slip out of the second groove section 212, thereby improving the bonding strength between the liner 200 and the ring cover 100.
[0046] Furthermore, the lining block 200 has a first end and a second end which are opposite to each other, and an end of the first groove section 211 away from the second groove section 212 is connected to the first end, and the protrusion 110 can slide into the first groove section 211 from the first end.
[0047] Specifically, one end of the first slot section 211 away from the second slot section 212 is connected to the first end, so that the protrusion 110 can slide into the first slot section 211 from the first end, which is convenient for assembly.
[0048] Furthermore, the second groove section 212 is connected to the second end, and the surface of the protrusion 110 is flush with the end surface of the second end.
[0049] When the protrusion 110 is in the second groove section 212, the protrusion 110 is flush with the end surface of the second end, so that the shape of the lining block 200 and the ring cover 100 on the second end plane is more regular, which is conducive to fully utilizing the space in the lock and reducing the volume of the lock.
[0050] Specifically, the assembly steps of the liner 200 and the ring cover 100 of the present application are as follows: first, align the protrusion 110 with the first groove section 211, and then gradually place the liner 200 into the ring cover 100 to allow the protrusion 110 to slide in the first groove section 211; when the protrusion 110 slides to the connection between the first groove section 211 and the second groove section 212, rotate the liner 200 to allow the protrusion 110 to slide along the second groove section 212 until the protrusion 110 slides to the end of the second groove section 212, and the assembly is completed.
