Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a split door lock. Background Art

[0002] In the general door lock structure, the lock head and the lock core are directly connected, that is, the lock core is directly driven by the components on the lock head, so there cannot be a certain distance between the two. If a door lock adopts this method, if it is applied to a rolling door, it is necessary to set a lock head and lock core at the bottom of the rolling door, and set a lock buckle on the ground to cooperate with the lock head and lock core. On the one hand, the lock buckle on the ground is exposed to the outside, which is unsafe, unsightly, or easy to damage. On the other hand, it can only apply the locking effect to one point on the rolling door, which may also cause unstable locking.

[0003] Based on the above example, a split structure in which the lock head is set in the middle of the door body and locked on one side of the lock head or on two opposite sides of the door body is more applicable, that is, locking is achieved on two opposite sides of the rolling door to avoid the appearance of the lock buckle on the ground. Therefore, it is necessary to design a door lock structure in which the lock head and the lock core can be locked on the basis of being set at a certain distance. Utility Model Content

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 4 As shown, a split door lock includes a lock head 1, a pull rope assembly 2, a lock core 3 and a buckle box 4. The lock head 1 is arranged on a door body (not shown). The lock head 1 includes a first shell 11, a rotating body 12 and a pull plate 13. The first shell 11 is arranged on the door body. The rotating body 12 is rotatably arranged on the first shell 11, and a pull plate 13 is arranged at one end of the door body. In the utility model, there are two lock cores 3. The two lock cores 3 are symmetrically arranged on opposite sides of the lock head 1 on the door body, and have a certain distance from the lock head 1, and are arranged on the same side as the pull plate 13. The lock core 3 includes a second shell 31, a hook plate 33 and a push plate 34. The second shell 3 1 is arranged on the door body, and the hook plate 33 is hinged on the rotating column 32 arranged on the second shell 31, that is, the hook plate 33 can rotate around the rotating column 32 to swing the hook head at its end, and a push plate 34 is hinged on the hook plate 33 at its non-hinged position, and the other end of the push plate 34 elastically abuts on the second shell 31. There are also two pull rope assemblies 2, one end of each pull rope assembly 2 is connected to the pull plate 13, and the other end is connected to a hook plate 33 of a lock cylinder 3, and the pull rope assembly 2 is driven by the pull plate 13 to rotate and drive the hook plate 33 to rotate, and the buckle box 4 is arranged on the door frame and has a socket 40 for accommodating the hook head at the front end of the hook plate 33.

[0027] In the present invention, after the operating rotating body 12 is rotated, it drives the pull plate 13 to rotate. The rotation of the pull plate 13 will drive the pull rope assembly 2 to tighten, and the hook plate 33 connected to the other end of the pull rope assembly 2 will be pulled up, and the hook head at the end of the hook plate 33 will be disengaged from the socket 40 on the buckle box 4, thereby realizing the unlocking function; when the operating rotating body 12 is rotated and reset, the force acting on the pull rope assembly 2 after the pull plate 13 rotates disappears, and the pull rope assembly 2 is reset. At this time, the force applied to the hook plate 33 by the pull rope assembly 2 disappears, and the push plate 34 elastically abutting against the second shell 31 applies a thrust to push the hook plate 33 to rotate around the rotating column 32 and reset it so that the hook head at the front end of the hook plate 33 is re-embedded in the socket 40 on the buckle box 4, thereby realizing the locking function.

[0028] The specific application scenarios of the utility model can be applied to rolling shutter doors, or other scenarios where locking is not performed at the lock head (locking needs to be performed at a certain distance on both sides of the lock head). Taking the rolling shutter door as an example, the lock head 1 can be set in the middle of the non-curled part of the door body, and a pair of lock cores 3 are set on opposite sides of the lock head 1 to form a split design. The pull rope assembly 2 is used to connect the lock head 1 and the lock core 3. After the buckle box 4 is set on the door frame, the door body and the door frame can be opened or locked. Therefore, it can be avoided to lock the rolling shutter door to the ground after the lock buckle and other components are set on the ground.

[0029] The utility model realizes the operation of the lock head 1 on the lock core 3 through a pull rope assembly 2 with a certain length. The pull rope assembly 2 is pulled to drive the hook plate 33 to disengage from the buckle box 4 to achieve unlocking, and the push plate 34 pushes the hook plate 33 to return to its original position and then embeds it into the buckle box 4 to achieve locking. Due to the extensibility of the pull rope assembly 2 in distance, the split design of the lock head 1 and the lock core 3 is realized, which is more adaptable to the needs of special locking scenarios.

[0030] More specifically, the push plate 34 includes a plate body 341, a limit plate 342 and a first spring 343. One end of the plate body 341 is hinged to the hook plate 33, and the hinge is located beside the rotating column 32, which can drive the hook plate 33 to rotate around the rotating column 32 so that the hook head at the end can swing. A limit plate 342 is provided on the side of the plate body 341 away from the hook plate 33. The first spring 343 is sleeved on the plate body 341, and the two ends are respectively abutted against the limit plate 342 and the second shell 31. The elastic recovery effect of the first spring 343 can push the plate body 341 to move.

[0031] Furthermore, the second shell 31 includes a guide plate 311 arranged on its main body, and a guide hole 310 is provided on the guide plate 311. One side of the plate body 341 extends into the guide hole 310 so that the two ends of the first spring 343 are respectively abutted against the limit plate 342 and the guide plate 311. The setting of the guide hole 310 can allow the plate body 341 to have space to move forward and backward on the one hand, and on the other hand, the movement of the plate body 341 can be limited by the cooperation with the structure on the plate body 341. For example, it can be limited to only being able to achieve translation relative to the through hole 310.

[0032] Based on the elastic pushing action of the push plate 34 and the setting of the guide hole 310, a limiting column 35 can be set on the second shell 31, and a card slot 330 can be set on the hook plate 33. After the card slot 330 abuts against the limiting column 35, the push plate 34 can be prevented from disengaging from the guide hole 310.

[0033] Combination Figure 2 and 3 As shown, the pull rope assembly 2 includes a pull rope 21 and a pull head 22. One end of the pull rope is arranged in the mounting hole 130 on the pull plate 13, and the other end is connected to the pull head 22. The pull head 22 is arranged on the hook plate 33. Specifically, an auxiliary plate 331 is provided on one side of the hook plate 33. One end of the pull head 22 passes through the auxiliary plate 331 to form a blocking end. The pull head 22 can move relative to the auxiliary plate 331. When the pull plate 13 rotates to a specific side (such as Figure 2 When the pull plate 13 rotates clockwise in the middle), the blocking end of the pull head 22 can be driven to abut against the auxiliary plate 331 through the pulling action of the pull rope 21 and drive the hook plate 33 to rotate so that the hook head at its end is separated from the buckle box 4 to complete the unlocking. Furthermore, a second spring 14 can be arranged between the pull plate 13 and the first shell 11, one end of the second spring 14 is hung in another mounting hole 130 on the pull plate 13, and the other end is hung in the hole on the first shell 11, so that after the pull plate 13 rotates to a specific side to complete the unlocking action, the second spring 14 and the first spring 343 cooperate to complete the reset of the pull rope 21, the hook plate 33 and other components.

[0034] In addition, a first guide member 15 and a second guide member 36 for guiding or steering the pull rope 21 are respectively provided on the first shell 11 and the second shell 31 , and a protective cover 23 can be provided on the outside of the pull rope 21 between the first guide member 15 and the second guide member 36 .

[0035] In the present invention, the pull plate 13 is a Z-shaped structure, which can extend to a certain depth in the door body and the first shell 11, and can pull the pull rope assembly 2 and the second spring 14 when it is driven to rotate.

[0036] The rotating body 12 can be in the form of an electronic lock, that is, it can be unlocked by fingerprint, password or face recognition and then driven to rotate, or it can be in the form of a mechanical lock, that is, the rotating body 12 is driven to rotate by inserting a key therein; of course, it can also be a simple cylinder, and the pull plate 13 is driven to rotate by the rotation of the cylinder.

[0037] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
