Detailed Implementation

[0023] 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.

[0024] The embodiments provided by this utility model are as follows: Figures 1-6 As shown, a double-groove lock handle for sliding doors designed to prevent accidental activation includes a base 10 with a limiting groove 20. A transmission rod 30 is mounted on the base 10 and slidably connected to the limiting groove 20. A rack 40 is fixedly mounted vertically on the transmission rod 30 at the front end of the limiting groove 20. An actuating component 50 is rotatably connected to the center of the base 10, with its actuating end meshing with the rack 40. The actuating component 50 drives the transmission rod 30 to slide vertically. A limiting hole 60 is provided at the rear end of the base 10, and a limiting component 70 is provided on the base 10. The limiting component 70 can be partially inserted into the limiting hole 60. The limiting component 70 is used to limit the transmission rod 30 from sliding in the vertical direction when it is unlocked. The base 10 is symmetrically provided with two locking hooks 80 at the horizontal center position. The two locking hooks 80 rotate around their own axis. The two ends of the transmission rod 30 are fixedly provided with convex shafts 90. The locking hooks 80 are provided with oblique grooves 100 that match the convex shafts 90. The two convex shafts 90 are respectively inserted into the two oblique grooves 100.

[0025] When opening the door, the user moves the actuating component 50 upwards. The actuating component 50 drives the rack 40 to slide through engagement, which in turn drives the transmission rod 30 to move downwards. The convex shafts 90 at both ends of the transmission rod 30 engage with the inclined grooves 100 on the two locking hooks 80 respectively. The downward movement of the transmission rod 30 causes the locking hooks 80 to retract and unlock. The user can then pull the handle 130 to the right to open the door. At this time, the limiting component 70 is partially inserted into the limiting hole 60 on the transmission rod 30, and the transmission rod 30 is fixed and limited. Even if the actuating component 50 is moved, the transmission rod 30 cannot move downwards, and the locking hooks 80 cannot extend. Thus, when opening the door, the actuating component 50 cannot be moved and the locking hooks 80 cannot extend, achieving the function of preventing accidental activation.

[0026] When closing the door, the user pushes the door lock to the left. The limiting component 70 is squeezed by the door frame and moves to the right. The limiting component 70 separates from the limiting hole 60 on the transmission rod 30, and the transmission rod 30 is unlocked. The user then pushes the actuating component 50 downward. The actuating component 50 drives the rack 40 to slide through meshing, which in turn drives the transmission rod 30 to move upward. The convex shafts 90 at both ends of the transmission rod 30 cooperate with the inclined grooves 100 on the lock hook 80. The upward movement of the transmission rod 30 causes the lock hook 80 to rotate and extend, realizing the door closing and locking function.

[0027] Preferably, the limiting component 70 includes a limiting seat 71, on which a spring 72 is fixedly sleeved. A contact rod 73 is fixedly provided at the end of the spring 72 away from the limiting seat 71. The setting direction of the contact rod 73 is perpendicular to the setting direction of the transmission rod 30. The contact rod 73 is partially disposed inside the limiting seat 71. A limiting block 74 is fixedly provided at the top of the contact rod 73. The limiting block 74 can be inserted into the limiting hole 60.

[0028] Preferably, the actuation assembly 50 includes a dial 51 and a paddle 52. The dial 51 is located at the center of the base 10 and the two are threaded together. The paddle 52 is sleeved on the dial 51 and meshes with the rack 40.

[0029] Preferably, the dial 51 includes a cylindrical rod 511 and a baffle 512. The cylindrical rod 511 is located at the center of the base 10 and the two are threaded together. The baffle 512 is fixedly located on the top of the cylindrical rod 511 and completely covers the top surface of the cylindrical rod 511.

[0030] Preferably, the paddle 52 includes a gear plate 521, which is sleeved on the cylindrical rod 511. The gear end of the gear plate 521 meshes with the rack 40. A lever 522 is fixedly provided on the non-gear end of the gear plate 521, and a lever 523 is fixedly provided on the end of the lever 522 away from the gear plate 521.

[0031] 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 limiting hole 60 is fixedly disposed at the rear end of one push rod 32. The two convex shafts 90 are respectively fixedly disposed at the rear ends of the two push rods 32.

[0032] Preferably, each of the two push rods 32 has a sliding hole 110, and the two locking hooks 80 are slidably connected to the matching sliding hole 110.

[0033] Preferably, a housing 120 is fixedly provided on the top of the base 10, the housing 120 covers the base 10 and the components on the base 10, and a handle 130 is fixedly provided on the housing 120.

[0034] The working principle of this embodiment, and its more specific process, are as follows:

[0035] When opening the door, the user moves the lever 523 upwards. The lever 523 drives the gear 521 to rotate around the cylindrical rod 511. The gear 521 drives the rack 40 to slide through meshing, which in turn drives the transmission rod 30 to move downwards. The convex shafts 90 at both ends of the transmission rod 30 respectively engage with the inclined grooves 100 on the two locking hooks 80. The downward movement of the transmission rod 30 causes the locking hooks 80 to retract and unlock. The user can then pull the handle 130 to the right to open the door. At this time, the contact rod 73 extends outwards under the action of the compressed spring 72. The limiting block 74 is partially inserted into the limiting hole 60 on the transmission rod 30, and the transmission rod 30 is fixed and limited. Even if the lever 523 is moved, the transmission rod 30 cannot move downwards, and the locking hooks 80 cannot extend. Therefore, when opening the door, the lever 523 cannot be moved and the locking hooks 80 cannot be extended, thus achieving the function of preventing accidental activation.

[0036] When closing the door, the user pushes the handle 130 to the left, and the contact rod 73 touches the fixed door frame. The contact rod 73 is squeezed by the door frame and moves to the right. At this time, the limiting block 74 on the contact rod 73 separates from the limiting hole 60 on the transmission rod 30, and the transmission rod 30 is unlocked. The user then moves the lever 523 downward, and the gear plate 521 meshes with the rack 40 on the transmission rod 30. The transmission rod 30 moves upward, and the convex shafts 90 at both ends of the transmission rod 30 cooperate with the inclined grooves 100 on the lock hook 80. The upward movement of the transmission rod 30 causes the lock hook 80 to rotate and extend, realizing the door closing and locking function.

[0037] This utility model's anti-accidental-touch sliding door double-groove lock handle features a transmission rod 30 mounted on a base 10, with a rack 40 fixed vertically on the transmission rod 30. A toggle assembly 50 is rotatably connected to the center of the base 10. A limit hole 60 is provided at the rear end of the transmission rod 30, and a limit assembly 70 is provided on the base 10, which can be partially inserted into the limit hole 60. Lock hooks 80 are symmetrically arranged along the horizontal center of the base 10. Protruding shafts 90 are fixedly provided at both ends of the transmission rod 30, and the lock hooks 80 have oblique grooves 100 that match the protruding shafts 90. This design ensures that the anti-accidental-touch sliding door double-groove lock handle automatically limits the transmission rod 30 when the door is open, preventing the lock hooks 80 from being accidentally extended. This provides high safety and a good user experience.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
