Description

Technical Field

[0001] The utility model relates to the technical field of locks, specifically to a flexible locking mechanism for a flat lock. Background Art

[0002] The flexible locking mechanism on traditional locks usually sets a locking component on the lock base body. The locking component includes a movable lock head arranged on the lock base body. The movable lock head is configured with a button, and a lock catch part for locking / unlocking cooperation with the lock head is arranged on the handle. By operating the button, the locking of the movable lock head to the lock catch part can be released. However, for some flat locks, in order to make the lock more compact and beautiful, on the one hand, the size of the tail end part of the lock base body is expected to be more compact, but in order to adapt to the installation and arrangement of the locking component, it is inevitable to increase the size space of the tail end part of the lock base body; on the other hand, there is a button on the surface of the lock base body, making the lock not simple and beautiful. Summary of the Invention

[0003] The invention purpose of the utility model: To overcome the defects existing in the prior art, the utility model provides a flexible locking mechanism for a flat lock with a simple and compact structure, reasonable installation and arrangement, and the advantage of low cost.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A flexible locking mechanism for a flat lock includes a lock base body and a handle. A handle groove is provided on the lock base body. One end of the handle is pivotally installed in the handle groove, and the other end of the handle is a tail end that can be inserted into / sprung out of the handle groove. Its characteristics are: A lock hole is provided at one end of the handle groove corresponding to the tail end of the handle. A slidable lock pin is provided at the end of the tail end of the handle. The lock pin has a locking head for locking / unlocking cooperation with the lock hole. The lock pin is configured with a locking spring. The locking spring drives the lock pin to slide to a locking position where the locking head can be latched with the lock hole. The locking / unlocking of the locking head and the lock hole is realized by operating the handle.

[0006] Preferably, a cooperation block is fixedly installed in the handle groove of the lock base body, and the lock hole is formed on the cooperation block.

[0007] Preferably, a placing table surface is provided in the handle groove. A positioning protrusion is provided on the placing table surface. A screw connection hole is provided on the positioning protrusion. A positioning depression is provided on the cooperation block. The positioning depression has a top plate with a screw hole. The positioning protrusion is inserted into the positioning depression, and the screw hole of the top plate corresponds to the screw connection hole in position. The cooperation block is fixed on the positioning protrusion by screws.

[0008] Preferably, the locking head is spherical.

[0009] By adopting the above technical solution, during the process of inserting the handle into the handle slot, the locking head is pressed. After the handle is inserted into the handle slot in place, the locking head of the lock pin is snapped into the lock hole to achieve temporary locking of the handle; by pulling the handle, the locking head is pressed out of the lock hole to complete the unlocking of the handle, and the operation is simple and convenient; the unlocking and locking of the flexible locking mechanism are achieved by means of the movement of the handle, without the need to specially set operation buttons, and the overall structure is simple and compact, realizing a hidden design, making the overall appearance of the lock clean and beautiful; and the lock pin and the locking spring are arranged on the handle, while the lock hole is arranged on the lock seat body, and the structure layout is reasonable, realizing a compact design of the overall structure of the lock.

[0010] The present invention will be further described below with reference to the accompanying drawings. Description of the Drawings

[0011] Figure 1 It is a schematic structural view of the flexible locking mechanism of the flat lock of the present invention;

[0012] Figure 2 It is an exploded view of the mounting structure of the mating block on the lock seat of the present invention;

[0013] Figure 3 It is a schematic structural view of the mating block of the present invention. Specific Embodiments

[0014] See the attached Figures 1 to 3 As shown, a flexible locking mechanism of a flat lock disclosed by the present invention includes a lock seat body 1 and a handle 2. A handle slot 11 is provided on the lock seat body 1. One end of the handle 2 is pivotally installed in the handle slot 11 through a steel bolt assembly 3. The other end of the handle 2 is a tail end 21 that can be inserted into / sprung out of the handle slot 11. A lock hole 12 is provided at one end of the handle slot 11 corresponding to the tail end 21 of the handle. A slidable lock pin 41 is provided at the end of the tail end 21 of the handle. A positioning hole is provided at the tail end 21 of the handle, and the lock pin 41 is restricted to slide in the positioning hole. The lock pin 41 has a locking head 411 that is locked / unlocked in cooperation with the lock hole 431. The lock pin 41 is configured with a locking spring 42. The locking spring 42 drives the lock pin 41 to slide to a locking position where the locking head 411 can be locked with the lock hole 431. The locking / unlocking of the locking head 411 and the lock hole 431 is achieved by operating the handle 2.

[0015] To facilitate the formation of the lock hole in the handle slot of the lock seat body, a mating block 43 is fixedly installed in the handle slot 11 of the lock seat body 1, and the lock hole 431 is formed on the mating block 43.

[0016] Further, a placement table surface 111 is provided in the handle groove 11. A positioning protrusion 112 is provided on the placement table surface 111. A screw connection hole 1121 is provided on the positioning protrusion 112. A positioning recess 432 is provided on the fitting block 43. The positioning recess 432 has a top plate with a screw hole 4321. The positioning protrusion 112 is inserted into the positioning recess 432, and the screw hole 4321 of the top plate corresponds to the screw connection hole 1121 in position. The fitting block 43 is fixed to the positioning protrusion 112 by screws. The positioning protrusion not only plays a positioning role, provides a position for setting the screw connection hole, realizes the installation and fixation of the fitting block, and realizes the convenient and reliable fixed installation of the fitting block.

[0017] When operating the handle, the locking head can be touched by the side wall of the lock hole. For better implementation, the locking head 411 is spherical; in the frequent operation process of flexible locking, the operation is smooth and wear is reduced.

[0018] After installation, there is no special button design on the outer surface of the lock, and the appearance is more tidy and beautiful; the design of the lock pin and the spring is adopted, which has the advantage of simple structure. The lock pin and the locking spring are arranged on the handle, and the lock hole is arranged on the lock seat body, and the structure is reasonably arranged to realize the compact design of the overall structure of the lock.
