When the handle 2 needs to be used, the handle 2 is pulled to turn along the hinge point thereof towards the direction departing from the door lock main body 1, and the handle 2 is separated from the abdicating groove 3. At the same time, the supporting block 4 is also separated from the grip 2, thereby realizing the taking of the grip 2.

When the handle 2 needs to be stored, the handle 2 is pushed to turn over along the direction of the hinge point of the handle towards the door lock main body 1, and the handle 2 is embedded into the abdicating groove 3. Meanwhile, the three side walls of the supporting block 4 abut against the three side inner walls of the grip 2, thereby accommodating the grip 2.

Referring to fig. 1 and 2, a locking mechanism 5 for fixing the handle 2 is fixedly connected to the door lock main body 1, and the locking mechanism 5 includes a mounting bracket 51 fixedly connected to the inside of the door lock main body 1 and a locking hook 52 rotatably connected to the mounting bracket 51.

Referring to fig. 1 and 2, the mounting bracket 51 includes a mounting plate 511 fixedly connected to an inner wall of the door lock body 1 on a side close to the grip 2, and both end portions of the mounting plate 511 are bent toward a direction away from the grip 2 and form hinge lugs 512. A hinge post 513 is rotatably connected between the two hinge lugs 512.

Referring to fig. 1 and 2, a mounting hole 6 is penetrated through a surface of the mounting plate 511, and a through-hole 7 aligned with the mounting hole 6 is penetrated through an inner wall of the door lock body 1. The hooking end of the locking hook 52 passes through the mounting hole 6 and the through hole 7 and then extends to the outside of the door lock body 1, and the other end is fixedly connected with the side wall of the hinge post 513.

Referring to fig. 2 and 3, a locking portion for hooking the locking hook 52 is fixedly connected to the handle 2, and the locking portion is a locking rod 8 horizontally and fixedly connected between the inner walls of the two sides of the handle 2. The door lock main body 1 is fixedly connected with a driving mechanism 9 for driving the locking hook 52 to overturn.

When the handle 2 needs to be unlocked, the driving mechanism 9 drives the locking hook 52 and the hinge column 513 to turn downwards, and the locking hook 52 is separated from the locking rod 8, so that the handle 2 is unlocked.

When the handle 2 needs to be locked, the driving mechanism 9 drives the locking hook 52 and the hinge column 513 to turn upwards, and the locking hook 52 is enabled to hook the locking rod 8, so that the handle 2 is locked.

Referring to fig. 1 and 2, a circular hole 10 penetrates through the outer wall of the door lock body 1 below the avoiding groove 3, and the driving mechanism 9 includes a lock cylinder 91 horizontally slidably connected with the circular hole 10. The inner wall of the door lock body 1 close to the grip 2 is horizontally and fixedly connected with a mounting pipe 11 which covers the round hole 10 and allows the lock cylinder 91 to slide.

Referring to fig. 2, an installation block 92 is fixedly connected to an upper end surface of the lock cylinder 91, and a limit groove 12 for slidably inserting the installation block 92 is formed in a side wall of an upper end of the installation tube 11.

When the handle 2 needs to be locked, the handle 2 is pushed to turn towards the door lock main body 1, and the locking rod 8 is enabled to collide with the locking hook 52. At this time, the latch hook 52 is turned downward by the interference of the lock lever 8, and the first spring 13 is placed in a stretched state.

When the hooking end of the locking hook 52 is aligned with the locking lever 8, the locking hook 52 is flipped upward by the elastic force of the first spring 13, and the locking hook 52 hooks the locking lever 8, thereby locking the grip 2.

When the handle 2 needs to be unlocked, the lock cylinder 91 is pressed to slide along the mounting tube 11, the mounting block 92 drives the hinge post 513 and the locking hook 52 to turn downwards under the driving of the lock cylinder 91, and then the locking hook 52 is separated from the locking rod 8, so that the handle 2 is unlocked.

Then the handle 2 is pulled to turn towards the direction away from the door lock body 1, and the latch hook 52 drives the hinge post 513 and the mounting block 92 to turn upwards under the elastic force of the first spring 13. At this time, the driving block 93 drives the lock cylinder 91 to slide along the mounting tube 11 under the interference of the mounting block 92.

Then, the mounting block 92 is driven by the lock cylinder 91 to be embedded into the limiting groove 12 until the side wall of the mounting block 92 is abutted against the inner wall of the limiting groove 12, so that the lock cylinder 91 and the mounting block 92 are reset.

Referring to fig. 1 and 4, a positioning block 14 is vertically and fixedly connected to a side wall of a lower end of the lock cylinder 91, and a positioning groove 15 for horizontally sliding the positioning block 14 is formed in an inner wall of the door lock main body 1 close to the grip 2.

Referring to fig. 1 and 4, a stopper 16 covering the positioning groove 15 is fixedly connected to an inner wall of the door lock body 1 on a side close to the grip 2, and a second spring 17 is horizontally and fixedly connected between the positioning block 14 and the stopper 16.

When the handle 2 is unlocked, the lock cylinder 91 slides along the installation tube 11, the positioning block 14 slides along the positioning slot 15 under the driving of the lock cylinder 91, and the second spring 17 is in a compressed state.

When the handle 2 is unlocked, the positioning block 14 slides along the positioning groove 15 under the elastic action of the second spring 17, and the positioning block 14 drives the lock cylinder 91 to slide along the mounting block 92, so that the lock cylinder 91 is quickly reset.

Referring to fig. 4, the key cylinder 91 includes a lock case 911 and a core 912 disposed in the lock case 911, the lock case 911 is horizontally slidably coupled to the mounting pipe 11, and the core 912 is horizontally rotatably coupled to the lock case 911.

Referring to fig. 4 and 5, a stopper 18 aligned with the port of the mounting pipe 11 is integrally formed on the upper end surface of the stopper 16, and a stopper hole 19 aligned with the lock cylinder 91 is formed through the sidewall of the stopper 18. The limiting hole 19 is bent inwards from the end opening at the side far away from the mounting tube 11 and forms a flange 20 against which a limiting plate 22 abuts.

Referring to fig. 4 and 5, a positioning plate 21 is vertically and fixedly connected to an end surface of the core 912 close to the mounting block 92, a limiting plate 22 is integrally formed at an upper end of the positioning plate 21, and the end surfaces of the limiting plate 22 and the limiting block 18 close to each other are abutted.

Referring to fig. 4 and 5, a notch 23 communicated with the limiting hole 19 is formed through the outer wall of the limiting block 18, and the notch 23 is used for the limiting plate 22 to be inserted after rotating.

When the lock is unlocked, the core 912 is driven to rotate, the positioning plate 21 and the limiting plate 22 are driven by the core 912 to synchronously rotate, and the limiting plate 22 is aligned with the notch 23. At this time, the lock cylinder 91 can be slidably inserted into the limiting hole 19, so that the driving mechanism 9 is unlocked and the cabinet door lock is unlocked.

When the lock is closed, the core body 912 is driven to rotate reversely, and the positioning plate 21 and the limiting plate 22 rotate synchronously in the same direction under the drive of the core body 912. Until the limit plate 22 and the limit block 18 are against each other, the lock core 91 cannot slide along the installation pipe 11, so that the locking of the driving mechanism 9 and the closing of the cabinet door lock are realized.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
