[0002] With the widespread use of sliding doors in homes, offices, and public spaces, the security and ease of use of their matching locks have become key requirements. Traditional sliding door locks mostly adopt a single groove lock structure, which only cooperates with the door frame latch through a single groove. Some single groove lock handle designs are not fully ergonomic, requiring adjustment of grip posture or application of greater pushing force during operation, which is not user-friendly, especially for the elderly and children. Against this background, double groove lock handles have emerged, becoming an important upgrade direction for sliding door locks.

Detailed Implementation

[0022] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] The embodiments provided by this utility model are as follows: Figures 1-6 As shown, a double-groove lock handle for a sliding door with a deadbolt function includes a base 10, a limiting groove 20 on the base 10, a transmission rod 30 on the base 10, the transmission rod 30 being slidably connected to the limiting groove 20, a rack 40 fixedly mounted vertically on the side of the transmission rod 30, the rack 40 being positioned at the front end of the limiting groove 20, a cylindrical rod 50 threadedly connected to the center of the base 10, and an actuating component 60 sleeved on the cylindrical rod 50, the actuating end of the actuating component 60 engaging with the rack 40. A dial 70 is fixedly installed at the front end of the column 50, and a lock cylinder 80 is fixedly installed on the dial 70. A deadbolt assembly 90 is installed on the base 10. The deadbolt assembly 90 is used to restrict the rotation of the actuation assembly 60 and the dial 70. A lock hook 110 is mirror-mounted on the base 10 along the horizontal center position. The lock hook 110 rotates around its own axis. A convex shaft 120 is fixedly installed at both ends of the transmission rod 30. A slanted groove 130 matching the convex shaft 120 is opened on the lock hook 110. The convex shaft 120 is inserted into the slanted groove 130.

[0024] When the door is opened, the user pushes the upward component 60. The component 60 drives the rack 40 to slide through the meshing mechanism, which in turn drives the transmission rod 30 to move downward. The convex shafts 120 at both ends of the bottom of the transmission rod 30 cooperate with the inclined grooves 130 on the lock hook 110. The downward movement of the transmission rod 30 causes the lock hook 110 to retract and unlock, allowing the user to open the door.

[0025] When closing the door, the user pushes the door lock to the left to close the sliding door. The user then moves the actuating component 60 downwards. The actuating component 60 drives the rack 40 to slide through engagement, which in turn drives the transmission rod 30 to move upwards. The convex shafts 120 at both ends of the bottom of the transmission rod 30 cooperate with the inclined grooves 130 on the lock hook 110. The upward movement of the transmission rod 30 causes the lock hook 110 to rotate and extend, realizing the door closing and locking function.

[0026] After the door lock is closed, the user turns the lock cylinder 80 with the key. The lock cylinder 80 drives the dial 70 to rotate, and the deadbolt component 90 disengages from the dial 70. The deadbolt component 90 restricts the rotation of the dial component 60, thus realizing the deadbolt function. At this time, only by resetting the lock cylinder 80, disengaging the deadbolt component 90 from the dial component 60, and restricting the rotation of the dial 70 again, can the door be unlocked freely.

[0027] Preferably, the actuating assembly 60 includes a gear plate 61, which is sleeved on the cylindrical rod 50. The gear end of the gear plate 61 meshes with the rack 40, and a lever 62 is fixedly disposed on the non-gear end of the gear plate 61.

[0028] Preferably, a lever 62 is fixedly provided with a lever 63 at the end away from the gear plate 61.

[0029] Preferably, the anti-locking assembly 90 includes a spring 91, which is fixedly mounted on the base 10. A stop block 92 is fixedly connected to the end of the spring 91 away from the base 10. An arc-shaped block 93 is integrally formed on the top front end of the stop block 92. A square groove 94 matching the stop block 92 is provided on the gear plate 61, and an arc-shaped groove 95 matching the arc-shaped block 93 is provided on the dial 70.

[0030] Preferably, the transmission rod 30 includes a concave rod 31 and two push rods 32. The two push rods 32 are respectively fixedly disposed at the upper and lower ends of the concave rod 31. The concave rod 31 is partially disposed in the limiting groove 20 and is slidably connected with the limiting groove 20. The rack 40 is fixedly disposed on the side wall of the concave rod 31. The two convex shafts 120 are respectively fixedly disposed at the rear ends of the two push rods 32.

[0031] Preferably, the top rod 32 has a sliding hole 140, and the two locking hooks 110 are slidably connected to the two sliding holes 140 respectively.

[0032] Preferably, a housing 150 is fixedly provided on the top of the base 10, the housing 150 covers the base 10 and the components on the base 10, the locking hook 110 can extend to the outside of the housing 150, the toggle assembly 60 is partially provided on the outside of the housing 150, and a handle 160 is fixedly provided on the housing 150.

[0033] The working principle of this embodiment, and its more specific process, are as follows:

[0034] When opening the door, the user moves the lever 63 upwards, and the gear 61 meshes with the rack 40 on the transmission rod 30. The transmission rod 30 moves downwards, and the convex shafts 120 at both ends of the bottom of the transmission rod 30 cooperate with the inclined grooves 130 on the lock hook 110. The downward movement of the transmission rod 30 causes the lock hook 110 to retract and unlock. The user can then pull the handle 160 to the right to open the door.

[0035] When closing the door, the user pushes the handle 160 to the left to close the sliding door. The user then moves the lever 63 downward, and the gear plate 61 meshes with the rack 40 on the transmission rod 30. The transmission rod 30 moves upward, and the convex shafts 120 at both ends of the bottom of the transmission rod 30 cooperate with the inclined grooves 130 on the lock hook 110. The upward movement of the transmission rod 30 causes the lock hook 110 to rotate and extend, realizing the door closing and locking function.

[0036] After the door lock is closed, the user turns the lock cylinder 80 with the key. The lock cylinder 80 drives the dial 70 to rotate. The arc-shaped block 93 on the stop 92 disengages from the arc-shaped groove 95 on the dial 70, and the spring 91 is compressed. The compressed spring 91 pushes the stop 92 to move. The stop 92 is embedded in the square groove 94 on the gear plate 61. The stop 92 restricts the rotation of the actuating component 60, realizing the anti-locking function. At this time, only by turning and resetting the lock cylinder 80 again, so that the arc-shaped block 93 on the stop 92 is re-embedded in the arc-shaped groove 95 on the dial 70, and the stop 92 is disengaged from the square groove 94 on the gear plate 61, can the actuating component 60 be rotated freely and the lock be unlocked.

[0037] This utility model discloses a sliding door double-groove lock handle with a deadbolt function. A limiting groove 20 is provided on the base 10, a transmission rod 30 is provided on the base 10, a rack 40 is fixedly provided vertically on the side of the transmission rod 30, a cylindrical rod 50 is threadedly connected to the center of the base 10, a toggle assembly 60 is sleeved on the cylindrical rod 50, the toggle end of the toggle assembly 60 meshes with the rack 40, a dial 70 is fixedly provided on the top of the cylindrical rod 50, a lock cylinder 80 is fixedly provided on the dial 70, a deadbolt assembly 90 is provided on the base 10, and a lock hook 110 is mirrored along the horizontal center of the base 10. This design enables the sliding door double-groove lock handle with a deadbolt function to have a limiting deadbolt function, a compact structure, is not easily damaged, has high security, and provides a good user experience.
