Description

Technical Field

[0001] This invention relates to the field of lock structure technology, and in particular to a lock and a lock assembly method. Background Technology

[0002] Locks, as important security devices, are widely used in various situations. The applicant found that traditional locks have certain limitations in structure and function, such as the inflexible adjustment of the extension length of the locking components and the relatively complex assembly process. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides a lock comprising a sharpener assembly, a locking assembly, a dial assembly, and an intermediate sleeve. The locking assembly is slidably inserted into the front end of the sharpener assembly. The dial assembly is rotatably disposed at the rear end of the sharpener assembly and is drivenly connected to the locking assembly. The intermediate sleeve is sleeved on the sharpener assembly, and one end of it is fixedly connected to a deadbolt panel. An elastic protrusion is provided on the outer side of the sharpener assembly. A semi-spiral guide groove is formed on the side of the intermediate sleeve. The elastic protrusion is placed in the guide groove. When the intermediate sleeve rotates relative to the sharpener assembly, the elastic protrusion moves relative to the guide groove, so that the intermediate sleeve retracts into the sharpener assembly or extends out of the sharpener assembly and partially covers the locking assembly, thereby adjusting the length of one end of the locking assembly extending from the deadbolt panel.

[0004] In some possible embodiments, both ends of the guide groove extend horizontally along the circumference of the intermediate sleeve to form locking sections. The two locking sections are respectively located on two symmetrical sides of the intermediate sleeve, and the distances between the two locking sections and the ends of the intermediate sleeve are not equal.

[0005] In some possible embodiments, the sharpening assembly includes two mirror-mounted and capped semi-cylinders, the elastic protrusion being formed on the outer side of one of the semi-cylinders, a side plate integrally formed at one end of the semi-cylinder, the sharpening locking assembly being slidably inserted between the two semi-cylinders, and the dial assembly being rotatably mounted between the two side plates.

[0006] In some possible embodiments, the barrel assembly further includes a clamping sleeve, one end of which is provided with a riveting claw. A riveting through hole is provided at the connection between the half-cylinder and the side plate. The clamping sleeve is fitted onto the half-cylinder and the riveting claw is bent and riveted into the riveting through hole to fix the two half-cylinders together.

[0007] In some possible embodiments, the side of the clamp is provided with an elastic inner protrusion, which is integrally formed with the clamp. The outer side of the intermediate sleeve is provided with two positioning pin holes, and the elastic inner protrusion can be inserted into the positioning pin holes.

[0008] In some possible embodiments, a linear spring is provided on the sharpening cartridge assembly at the lower end of the dial assembly. Rotating the dial assembly can drive the locking assembly to retract into the sharpening cartridge assembly, while the lower end of the dial assembly presses against the linear spring.

[0009] The present invention also provides a lock assembly method, which is capable of assembling locks as described in the above embodiments, and the lock assembly method includes the following steps:

[0010] Step S100: Connect the two half-cylinders together, insert the clamp into one end of the side plate, insert the clamp into the connection between the side plate and the half-cylinder, then rivet the rivet claw at the end of the clamp and insert it into the rivet through hole on the side wall of the half-cylinder to connect and fix the two half-cylinders to obtain the cylindrical assembly.

[0011] Step S200: Insert the intermediate sleeve into the front end of the sharpening cylinder assembly, and place the elastic protrusion on the half-cylinder into the guide groove on the intermediate sleeve, driving the intermediate sleeve to rotate relative to the sharpening cylinder assembly to adjust the depth of the intermediate sleeve inserted into the sharpening cylinder assembly.

[0012] Step S300: Insert the sharpening component into the front end of the sharpening cylinder assembly, so that the sharpening component can be slidably placed in the two half-cylinders;

[0013] Step S400: Install the baffle and the deadbolt panel in sequence at one end of the intermediate sleeve, and rivet the intermediate sleeve and the deadbolt panel together.

[0014] Step S500: Install the dial assembly between the two side plates, so that the dial assembly is rotatably placed inside the side plates, and one end of the dial assembly is driven to be connected to one end of the locking assembly. When the dial assembly is rotated, the locking assembly can be driven to retract into the semi-cylinder.

[0015] In step S600, a linear spring is fitted inside the two side plates at the lower end of the dial assembly. The linear spring is arranged horizontally and always abuts against the lower end of the dial assembly.

[0016] In some possible embodiments, in step S200, the intermediate sleeve is rotated 180° until the elastic inner protrusion on the sleeve assembly engages with the positioning pin hole on the side wall of the intermediate sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The structure is reasonably designed, and the extension length of the locking component is flexibly adjustable to meet the needs of different usage scenarios;

[0019] 2. The assembly process is simple and convenient, improving assembly efficiency and product quality;

[0020] 3. The connections between all components are firm and reliable, ensuring the stability and safety of the lock during use;

[0021] 4. The design of the elastic protrusion and the guide groove enables the intermediate sleeve to achieve a self-locking function, preventing accidental rotation and improving the safety of the lock. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0030] Reference Figures 1 to 3 The lock shown includes a sharpener assembly 1, a locking assembly 2, a dial assembly 3, and an intermediate sleeve 4. The sharpener assembly 1 is formed by two mirror-shaped semi-cylindrical bodies 11, which are closed and fixed together. One of the semi-cylindrical bodies 11 has an elastic protrusion 12 on its outer surface. A side plate 13 is integrally formed at one end of the semi-cylindrical body 11. The locking assembly 2 is slidably inserted between the two semi-cylindrical bodies 11. The dial assembly 3 is rotatably mounted between the two side plates 13. The dial assembly 3 is drivenly connected to the locking assembly 2, that is, rotating the dial assembly 3 can drive the locking assembly 2 to retract into the sharpener assembly. Inside component 1, the intermediate sleeve 4 is sleeved on the sharpening assembly 1 and one end of it can be fixedly connected to the locking panel 6. The side of the intermediate sleeve 4 is provided with a semi-spiral guide groove 41. The elastic protrusion 12 is placed in the guide groove 41. When the intermediate sleeve 4 rotates relative to the sharpening assembly 1, the elastic protrusion 12 moves in the guide groove 41, so that the intermediate sleeve 4 can move axially relative to the sharpening assembly 1 and retract into the sharpening assembly 1 or extend out of the sharpening assembly 1 and partially cover the locking assembly 2, thereby adjusting the length of one end of the locking assembly 2 extending out of the locking panel 6.

[0031] In some possible embodiments, both ends of the guide groove 41 extend horizontally along the circumference of the intermediate sleeve 4 to form locking sections 42. The two locking sections 42 are respectively located on two symmetrical sides of the intermediate sleeve 4, and the distances between the two locking sections 42 and the ends of the intermediate sleeve 4 are not equal. This design enables the intermediate sleeve 4 to achieve a self-locking function after rotation. That is, during adjustment, the intermediate sleeve 4 can be rotated to move the elastic protrusion 12 from one locking section 42 to the other locking section 42, preventing the intermediate sleeve 4 from rotating accidentally in the non-adjusted state, thereby ensuring the stability of the extension length of the locking assembly 2.

[0032] In some possible embodiments, the sharpening cylinder assembly 1 further includes a clamping cylinder 14, one end of which is provided with a riveting claw 141. A riveting through hole 111 is provided at the connection between the half-cylinder 11 and the side plate 13. The clamping cylinder 14 is inserted into the half-cylinder 11 from one end of the side plate 13, and the riveting claw 141 is bent and riveted into the riveting through hole 111 to fix the two half-cylinders 11. The sharpening cylinder assembly 1 of the present invention integrates the side plate 13 and the half-cylinder 11 into one piece, which effectively improves the structural strength between the half-cylinder 11 and the side plate 13 and avoids the problem of bending or even breaking between the side plate 13 and the half-cylinder 11 when subjected to external force. The two half-cylinders 11 are then riveted and fixed by the clamping cylinder 14, which solves the problems of insufficient connection strength and low assembly efficiency in the prior art. It has the advantages of simple structure, stable connection and convenient assembly.

[0033] In some possible embodiments, the side of the clamping sleeve 14 is provided with an elastic inner protrusion 15, and the outer side of the intermediate sleeve 4 is provided with two positioning pin holes 43. The elastic inner protrusion 15 can be inserted into the positioning pin holes 43. While the intermediate sleeve 4 rotates relative to the sharpening sleeve assembly 1 to adjust its extension length to the correct position, the elastic inner protrusion 15 is inserted into the positioning pin holes 43 to prevent the intermediate sleeve 4 from rotating accidentally in the non-adjusted state, thereby ensuring the stability of the extension length of the sharpening assembly 2.

[0034] In some possible embodiments, a linear spring 5 is provided on the lower end of the lever assembly 3 on the sharpener assembly 1. Rotating the lever assembly 3 drives the locking sharpener assembly 2 to retract into the sharpener assembly 1, while the lower end of the lever assembly 3 presses against the linear spring 5. The linear spring 5 allows the locking sharpener assembly 2 to generate a certain elastic restoring force when retracting into the sharpener assembly 1. Thus, when the external force on the lever assembly 3 is removed, it can quickly reset through the elastic restoring force of the linear spring 5, improving the ease of use of the lock.

[0035] Reference Figure 4 The method for assembling a lock, as shown, includes the following steps:

[0036] In step S100, the two semi-cylinders 11 are closed and connected. A clamping sleeve 14 is inserted from the rear end of the side plate 13, fitting the clamping sleeve 14 to the connection between the side plate 13 and the semi-cylinders 11. The riveting claws at the end of the clamping sleeve 14 are then riveted, bent, and inserted into the riveting through-holes on the side wall of the semi-cylinders 11, thus connecting and fixing the two semi-cylinders 11 to obtain the sharpening assembly 1. In this step, by closing and connecting the two semi-cylinders 11 and fixing them using the clamping sleeve 14, the basic structure of the sharpening assembly 1 is formed. The riveting claws of the clamping sleeve 14, bent and inserted into the riveting through-holes on the side wall of the semi-cylinders 11, ensure a tight connection between the two semi-cylinders 11.

[0037] In step S200, the intermediate sleeve 4 is inserted onto the front end of the sharpening assembly 1, and the elastic protrusion 12 on the half-cylinder 11 is placed in the guide groove 41 on the intermediate sleeve 4. This causes the intermediate sleeve 4 to rotate relative to the sharpening assembly 1 to adjust the depth of the intermediate sleeve 4 inside the sharpening assembly 1. In this step, the intermediate sleeve 4 is inserted into the front end of the sharpening assembly 1, and the relative rotation between the intermediate sleeve 4 and the sharpening assembly 1 is achieved through the cooperation of the elastic protrusion 12 and the guide groove 41. By rotating the intermediate sleeve 4, the depth of the intermediate sleeve 4 inside the sharpening assembly 1 can be adjusted, thereby providing suitable space for the subsequent installation of the locking assembly 2. Further, in this step, the intermediate sleeve 4 is rotated half a turn until the elastic inner protrusion 15 on the sharpening assembly 1 rotates from the positioning pin hole 43 on the side wall of the intermediate sleeve 4 and engages with another positioning pin hole 43 on the side wall of the intermediate sleeve 4, thereby achieving the positioning and fixation between the intermediate sleeve 4 and the sharpening assembly 1. This design allows the intermediate sleeve 4 to be accurately positioned during adjustment, improving the assembly precision of the lock.

[0038] In step S300, the sharpening component 2 is inserted into the front end of the sharpening cylinder assembly 1, so that the sharpening component 2 is slidably placed within the two semi-cylinders 11. In this step, the sharpening component 2 is inserted into the front end of the sharpening cylinder assembly 1 and can slide between the two semi-cylinders 11. The sliding performance of the sharpening component 2 allows it to extend or retract as needed during use, thereby realizing the locking and unlocking functions of the lock.

[0039] In step S400, the baffle 61 and the deadbolt panel 6 are sequentially installed at one end of the intermediate sleeve 4, and then riveted together to secure them. In this step, the baffle 61 and the deadbolt panel 6 are sequentially installed at one end of the intermediate sleeve 4 and secured by riveting. The installation of the baffle 61 and the deadbolt panel 6 allows the lock to connect to an external structure, improving the ease of use of the lock.

[0040] In step S500, the dial assembly 3 is installed between the two side plates 13, so that the dial assembly 3 is rotatably placed inside the side plates 13, and one end of the dial assembly 3 is drivenly connected to one end of the locking assembly 2. Rotating the dial assembly 3 can drive the locking assembly 2 back into the semi-cylinder 11. In this step, the dial assembly 3 is installed between the two side plates 13 and drivenly connected to the locking assembly 2. By rotating the dial assembly 3, the locking assembly 2 can be driven back into the semi-cylinder 11, thereby realizing the opening operation of the lock.

[0041] In step S600, a linear spring 5 is fitted onto the lower end of the dial assembly 3 within the two side plates 13. The linear spring 5 is horizontally arranged and always abuts against the lower end of the dial assembly 3. In this step, the linear spring 5 is fitted onto the lower end of the dial assembly 3 and is arranged horizontally. The linear spring 5 allows the locking assembly 2 to generate a certain elastic restoring force when retracted into the locking sleeve assembly 1, thereby enabling it to quickly extend when needed, improving the ease of use of the lock.
