Description

Technical field:

[0001] The utility model relates to the field of lock bodies, in particular to a novel door and window lock body. Background technology:

[0002] In order to increase the beauty of interior decoration and reduce space occupancy, more families choose to install sliding metal glass doors when decorating their balconies. Existing sliding metal glass doors are generally installed with double hook locks. The two hook locks of the double hook lock can enhance the locking effect. However, in related technologies, the two hook locks of the double hook lock are individually controlled to open or close by different components. During the unlocking process, different components need to be operated to open the two hook locks separately, and the door opening operation process is relatively complicated.

[0003] In order to solve this problem, patent document CN216690680U discloses a double-hook lock. During the unlocking process, the paddle of the lock core rotates clockwise to push the linked push rod, the linked push rod drives the second connecting rod to move, the second connecting rod drives the second support rod to move, thereby driving the screwing glove to rotate to retract the first lock hook into the lock shell; the paddle of the lock core rotates counterclockwise to drive the second driving member to rotate and retract the second lock hook into the lock shell. By controlling the rotation of the lock core, the first lock hook and the second lock hook can be retracted, thereby achieving the purpose of unlocking, and the unlocking operation is convenient.

[0004] However, the first and second hooks of the double-hook lock structure are synchronized by a linkage mechanism, which is complex and unstable. In addition, since the opening and closing of the first and second hooks are controlled by a lock cylinder, the user needs a key to lock the sliding door, which is inconvenient. Utility model content:

[0026] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0027] like Figures 1 to 6 As shown, this embodiment provides a new door and window lock body, including a lock shell 1, a lock nail 2 is fixed in the lock shell 1, and a rotatable lock hook 3 is sleeved on the lock nail 2. The lock hook 3 rotates on the lock nail 2 and rotates from the lock shell 1 to the outside of the lock shell 1 to hook the door frame or the corresponding glass door. A push piece 4 is provided on the surface of the lock hook 3 in the lock shell 1, and a push rod 31 is fixed on the lock hook 3. A sliding groove 41 is reserved on the push piece 4 for matching with the push rod 31. When the push piece 4 moves up and down, the push rod 31 moves in the sliding groove 41 to push the lock hook 3 to rotate. The lock hook 3 is rotated by the up and down movement of the push piece 4, thereby playing the role of a switch. This new door and window lock body has the advantages of simple structure, easy use, safety and reliability.

[0028] Preferably, two locking hooks 3 are provided, which are placed symmetrically and hooked in relative directions. At the upper locking hook 3, the pushing rod 31 is located in the lower rear direction of the locking hook 3, and it is easier to be pushed by the pushing piece 4 in this direction. At the lower locking hook 3, the pushing rod 31 is located in the lower front direction of the locking hook 3, and it is easier to be pushed by the pushing piece 4 in this direction. The structure of the pushing piece 4 can solve the problem of the overall space being too large. Because of its small volume, it greatly saves the volume occupied during installation and greatly saves the cost of production raw materials.

[0029] Preferably, the sliding groove 41 includes a longitudinal groove 410 and a transverse groove 411, and the intersection of the longitudinal groove 410 and the transverse groove 411 is set as a chamfered structure 412. The transverse groove 411 of the upper sliding groove 41 extends toward the rear side, and the transverse groove 411 of the lower sliding groove 41 extends toward the front side. The push rod 31 is guided in the longitudinal groove 410 to the chamfered structure 412 and moves toward the transverse groove 411. This method has a simple structure, the push piece 4 moves up and down more smoothly, and the lock hook 3 rotates more flexibly to avoid jamming.

[0030] Preferably, two first spring columns 11 are provided in the lock housing 1, the push piece 4 is located on one side of the first spring column 11, a second spring column 42 is fixed on the push piece 4, and a spring is provided between the first spring column 11 and the second spring column 42. The spring can allow the push piece 4 to maintain its position at one end and not slide easily.

[0031] Preferably, a pushing block 43 is provided at one end of the pushing piece 4, a lock head is provided on the lock shell 1, and a swinging part 5 is provided on the lock head. The swinging part 5 rotates to push the pushing block 43 to move the pushing piece 4 up and down. The pushing block 43 is used to be pushed by the swinging part 5 to move the pushing piece 4 up and down.

[0032] Preferably, a lining plate 6 is provided on the side of the lock housing 1 , and a first through hole 61 is provided on the lining plate 6 through which the lock hook 3 extends.

[0033] Preferably, the surface of the lock shell 1 is provided with a panel 7, which is used to be installed on the frame of the glass door. A panel switch 71 that slides up and down is installed on the panel 7. A middle rod 72 is provided at the bottom of the panel switch 71, which is used to pull the panel switch 71 so that the middle rod 72 pushes the push piece 4 to rotate the lock hook 3. The lock shell 1 and the push piece 4 are provided with a second through hole 12, and the middle rod 72 is inserted into the second through hole 12 to push the push piece 4 to move up and down.

[0034] In the prior art, a certain thrust is generated in the process of pushing the push block 43 to push the lock shell 1, which is easy to damage the lock shell 1. Therefore, a buffer block 8 is provided at the end position of the lock shell 1. The buffer block 8 is provided at both ends of the lock shell 1 to reduce the thrust and improve the service life.

[0035] Preferably, the lock housing 1 includes an upper lock housing 13 and a lower lock housing 14 , and the upper lock housing 13 covers the lower lock housing 14 .

[0036] In the prior art, the first and second hooks of a double-hook lock are synchronized by a connecting rod mechanism, resulting in a complex structure and poor stability. Furthermore, since the double-hook lock controls the opening and closing of the first and second hooks via a lock cylinder, a user needs a key to lock the sliding door, which is inconvenient. Therefore, a novel door and window lock body is provided, wherein a push piece 4 is provided on the surface of the hook 3 within the lock housing 1, a push rod 31 is fixedly provided on the hook 3, and a sliding groove 41 is provided on the push piece 4 for the push rod 31 to cooperate with. When the push piece 4 moves up and down, the push rod 31 moves within the sliding groove 41, thereby pushing the hook 3 to rotate. The upward and downward movement of the push piece 4 causes the hook 3 to rotate, thereby acting as a switch. This novel door and window lock body has the advantages of simple structure, ease of use, safety, and reliability.

[0037] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention are equivalent replacement methods and are included in the scope of protection of the present invention.
