Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a lock that is easy to disassemble. Background Technology

[0002] Locks are devices that serve a sealing function, including locks, keys, and their accessories. Generally, they are defined as "sealing devices that can only be opened with a key." Besides keys, locks can also be opened using light, electricity, magnetism, sound, and fingerprint signals. Locks are integral to people's daily lives; every household needs different types. Locks are not only used on residential doors but also on the doors of some tricycles or work vehicles.

[0003] Locks on the doors of tricycles or work vehicles are prone to damage due to frequent use and harsh environments. Current tricycle door locks require an external mounting shell for installation, necessitating precise positioning of the shell and alignment of the latch plate with the unlocking mechanism on the outer door. This cumbersome installation process fails to meet the need for quick lock replacement. Therefore, further improvements to the existing lock structure are necessary. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a lock that is easy to disassemble, which can effectively solve the problems of the cumbersome installation process and inability to meet the needs of quick replacement of existing locks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lock that is easy to disassemble includes a mounting base, a first elastic element, a tongue plate, a lock shell, a lock cylinder, and a locking plate. The mounting base is movably disposed in an external mounting position and is cylindrical. The first elastic element is sleeved on the outer wall of the mounting base, with its two ends abutting against the mounting base and the external mounting position, respectively, causing the mounting base to move outward. The tongue plate is detachably disposed at the inner end of the mounting base and moves back and forth with the mounting base. Under the action of the first elastic element, the tongue plate adheres to the side wall of the external mounting position. The lock shell is disposed at the outer end of the mounting base and has a pressing surface at its outer end. The lock shell has a mounting cavity inside. The lock cylinder is rotatably disposed in the mounting cavity, with its inner end extending inward into the mounting base and having a lock hole with an open outer end. The locking plate is disposed at the inner end of the lock cylinder and extends outward from the outer wall of the mounting base as the lock cylinder rotates, engaging and locking with the external mounting position.

[0007] As a preferred embodiment, the inner end face of the mounting base is provided with a first mounting hole, and the tongue plate is provided with a second mounting hole that mates with the first mounting hole. A fixing bolt passes through the second fixing hole and the first fixing hole in sequence to detachably mount the tongue plate onto the mounting base.

[0008] As a preferred embodiment, the lock housing has a first mounting groove that extends radially and communicates with the mounting cavity. The first mounting groove penetrates the outer side wall of the lock housing, and there are multiple first mounting grooves arranged at intervals along the extension direction of the mounting cavity. The lock cylinder has multiple second mounting grooves that mate with the lock hole and communicate with the first mounting grooves. The multiple first mounting grooves and the multiple second mounting grooves communicate to form multiple radially extending movable grooves. Each movable groove is provided with a plate-laying assembly. The inner end of the plate-laying assembly extends inward into the lock hole, and the outer end of the plate-laying assembly is connected to the lock housing by a second elastic element.

[0009] As a preferred embodiment, a sleeve is fitted onto the outer wall of the lock housing, and the two ends of the second elastic element abut against the inner wall of the sleeve and the outer end of the plate assembly, respectively.

[0010] As a preferred embodiment, the tray assembly includes a first tray and a second tray that are separately arranged. The first tray is located in a first mounting groove, and the second tray is located in a second mounting groove. The lower end of the second tray extends downward into the lock hole, and the upper end of the first tray contacts a second elastic element and, under the action of the second elastic element, drives the second tray to move toward the lock hole.

[0011] As a preferred embodiment, the mounting base is provided with a radially extending movable cavity, the inner end of the lock cylinder extends inward into the movable cavity, and the locking plate is located in the movable cavity and moves back and forth along the movable cavity under the drive of the lock cylinder.

[0012] As a preferred embodiment, the inner end of the lock cylinder extends outward with an eccentrically positioned connecting post, and the locking plate has a sliding groove perpendicular to the direction of movement of the locking plate, with the connecting post extending inward into the sliding groove.

[0013] As a preferred embodiment, the sidewall of the movable cavity is provided with a limiting groove in the same direction as the extension of the movable cavity, and the two sidewalls of the locking plate extend inward into the corresponding limiting grooves.

[0033] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a mounting base 10, a first elastic element 20, a tongue plate 30, a lock housing 40, a lock cylinder 50, and a locking plate 6.

[0034] The mounting base 10 is movably disposed in an external mounting position, and the mounting base 10 is cylindrical. In this embodiment, a first mounting hole 101 is provided on the inner end face of the mounting base 10. A radially extending movable cavity 102 is provided inside the mounting base 10. A limiting groove 103 with the same extension direction as the movable cavity 102 is provided on the side wall of the movable cavity 102.

[0035] The first elastic element 20 is sleeved on the outer wall of the mounting base 10. The two ends of the first elastic element 10 abut against the mounting base 10 and the external mounting position respectively, causing the mounting base 10 to move outward. In this embodiment, the first elastic element 20 is a spring.

[0036] The tongue plate 30 is detachably mounted on the inner end of the mounting base 10 and moves back and forth with the mounting base 10. At the same time, the installation angle of the tongue plate 30 can be adjusted through the detachable installation process of the tongue plate 30, so as to facilitate cooperation with the outside. The tongue plate 30 is attached to the side wall of the external mounting position under the action of the first elastic member 20. In this embodiment, the tongue plate 30 is provided with a second mounting hole 301 that cooperates with the first mounting hole 101. A fixing bolt 31 passes through the second fixing hole 301 and the first fixing hole 101 in sequence to detachably mount the tongue plate 30 on the mounting base 10.

[0037] The lock housing 40 is disposed at the outer end of the mounting base 10, and the outer end of the lock housing 40 has a pressing surface 41. The lock housing 40 has a mounting cavity 401. When unlocking the car door, it is only necessary to press the pressing surface 41 of the lock housing 40, and then the mounting base 10 drives the tongue plate 30 to move inward, thereby realizing the unlocking process through the cooperation of the tongue plate 30 with the corresponding external locking structure. In this embodiment, the lock housing 40 is provided with a first mounting groove 402 that extends radially and communicates with the mounting cavity 401. The first mounting groove 402 penetrates the outer side wall of the lock housing 40, and there are multiple first mounting grooves 402 arranged at intervals along the extension direction of the mounting cavity 401.

[0038] The lock cylinder 50 is rotatably disposed in the mounting cavity 401. The inner end of the lock cylinder 50 extends inward into the mounting base 10. The lock cylinder 50 has a lock hole 501 with an outer opening. In this embodiment, the lock cylinder 50 is provided with a plurality of second mounting grooves 502 that cooperate with the lock hole 501 and communicate with the first mounting groove 402. The plurality of first mounting grooves 402 and the plurality of second mounting grooves 502 communicate to form a plurality of radially extending movable grooves 503. Each movable groove 503 is provided with a plate-arranging assembly 51. The inner end of the plate-arranging assembly 51 extends inward into the lock hole 501. The outer end of the plate-arranging assembly 51 is connected to the lock housing 40 through a second elastic element (not shown in the figure). A sleeve 42 is fitted onto the outer wall of the lock housing 40. The two ends of the second elastic element (not shown) abut against the inner wall of the sleeve 42 and the outer end of the plate assembly 51, respectively. Since the first mounting groove 402 and multiple sets of the second elastic elements (not shown) are arranged at equal angles in most cases, the sleeve 42 can simultaneously limit and fix the outer end of the second elastic element (not shown), further facilitating the internal assembly process of the lock. The inner end of the lock cylinder 50 extends inward into the movable cavity 102. An eccentrically positioned connecting post 52 extends outward from the inner end of the lock cylinder 50.

[0039] The plate arrangement assembly 51 includes a first plate arrangement 511 and a second plate arrangement 512, which are separately arranged. The first plate arrangement 511 is located in a first mounting groove 402, and the second plate arrangement 512 is located in a second mounting groove 502. The lower end of the second plate arrangement 512 extends downward into the lock hole 501. The upper end of the first plate arrangement 511 contacts a second elastic element (not shown) and, under the action of the second elastic element (not shown), drives the second plate arrangement 512 to move towards the lock hole 501. When unlocking the lock cylinder 50, an external key is inserted, which then sequentially drives the lower end of the second plate arrangement 512 to move upward, so that the contact surfaces of the first plate arrangement 511 and the second plate arrangement 512 in each plate arrangement assembly 51 are flush with the contact surfaces of the lock cylinder 50 and the lock shell 40, thereby realizing the unlocking rotation process of the lock cylinder 50.

[0040] The locking plate 60 is located at the inner end of the lock cylinder 50. As the lock cylinder 50 rotates, the locking plate 60 extends outward from the outer wall of the mounting base 10 and engages with the external mounting position for locking. When the locking plate 60 is locked to the outside, the lock cylinder 50 and the lock housing 40 are locked together front and back, making it impossible to unlock the external position by pressing the pressing surface 41 of the lock housing 40. Unlocking can only be achieved by rotating the lock cylinder 50 to retract the locking plate 60 into the mounting base 10. In this embodiment, the locking plate 60 is located in the movable cavity 102 and moves back and forth along the movable cavity 102 under the drive of the lock cylinder 50. A sliding groove 601 perpendicular to the direction of movement of the locking plate 60 is provided inside the locking plate 60, and the connecting post 52 extends inward into the sliding groove 601. The two side walls of the locking plate 60 extend inward into the corresponding limiting grooves 103. Through the cooperation between the locking plate 60 and the limiting grooves 103, the movement of the locking plate 60 is limited, preventing the locking plate 60 from shifting and ensuring the stability of the unlocking process.

[0041] The key design feature of this invention is that the two ends of the first elastic element abut against the mounting base and the external mounting position respectively, causing the mounting base to move outward; and the tongue plate is detachably set at the inner end of the mounting base and moves back and forth with the mounting base. Under the action of the first elastic element, the tongue plate adheres to the side wall of the external mounting position. Therefore, during installation, it is only necessary to first remove the tongue plate, then extend the mounting base inward into the external mounting position, and then install the tongue plate at the inner end of the mounting base. Under the action of the first elastic element, the tongue plate is pressed and fixed together with the side wall of the mounting position, thus completing the installation process of the lock. During disassembly, it is only necessary to remove the tongue plate and then remove the mounting base. The overall installation and disassembly process is more convenient and can meet the user's need for quick lock replacement.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
