[0002] In the existing sliding doors and windows, a handle is usually used to drive a lock tongue to achieve the locking of the sliding doors and windows. However, in actual operation, the following technical problems exist: 1. When the sash profile is not fully fitted and touched with the frame profile, the operator turns the handle to lock it. At this time, the sliding doors and windows are not sealed in place, and locking at this time will also cause the lock tongue to be misplaced, and the locking function cannot be achieved. This insufficient fit and touch cannot be directly observed by the operator, and the fit state needs to be confirmed multiple times before locking to ensure the success of the locking; 2. The lock tongue is only locked to the doors and windows by rotating the handle, which is easily unlocked by rotating the handle from the outside, and its anti-theft performance is weak; 3. When the handle is rotated to lock, there is only a lock tongue at the handle. When the sash profile of the door and window is subjected to force, the force will be concentrated on the lock tongue, which is prone to stress fracture.

DETAILED DESCRIPTION

[0017] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0018] See also Figure 1-4The utility model provides a multi-point lock hook lock, the main body of which is a lock box 1, and a mounting panel 2 is provided on the top of the lock box 1. It also includes a movable plate 3, a rotating member 4, a lock core 5, a hook tongue anti-theft insurance 5.2 and a hook tongue anti-misoperation device 6.

[0019] The rotating member 4 is arranged in the lock box 1, and the rotating member 4 is provided with a gear 4.1 structure on the periphery of the rotating member 4. A handle is arranged on one side of the rotating member 4, and the rotating member 4 can be driven to rotate by rotating the handle. A hook tongue is arranged on the rotating member 4, and the movable plate and the mounting panel are provided with corresponding through grooves, so that the hook tongue can extend from the movable plate and the mounting panel after rotation.

[0020] The movable plate 3 is arranged at the bottom of the mounting panel 2. A rack 3.1 is provided at the bottom of the movable plate 3 to cooperate with a gear 4.1 on the peripheral side of the rotating member 4. The rotating member 4 rotates to drive the movable plate 3 to move left and right. The extended sections 3.3 at the left and right ends of the movable plate 3 are provided with one or more locking points 3.2.

[0021] The lock box 1 is also provided with a lock core 5, and a lock core pulsator 5.1 is provided on the outer side of the lock core 5. A hook tongue anti-theft insurance 5.2 is provided on one side of the lock core pulsator 5.1. The hook tongue anti-theft insurance 5.2 is located on one side of the rotating member 4. The lock core pulsator 5.1 can drive the hook tongue anti-theft insurance 5.2 to move up and down, so that after the hook tongue anti-theft insurance 5.2 moves upward, it will get stuck in the rotating member, so that the rotating member cannot rotate. Specifically, a longitudinal through groove is provided on one side of the lock box 1, and a protruding part of the hook tongue anti-theft insurance 5.2 is stuck in the through groove, so that the hook tongue anti-theft insurance 5.2 can move up and down in a limited position in the lock box 1. A first protruding extension section and a second protruding extension section are respectively arranged on the upper and lower sides of the hook tongue anti-theft insurance 5.2 near the lock core wave wheel 5.1. The two extension sections produce a blocking collision with the lock core wave wheel 5.1. When the lock core wave wheel 5.1 collides with the first extension section on the upper side of the hook tongue anti-theft insurance 5.2, the hook tongue anti-theft insurance 5.2 is driven to slide upward along the groove of the lock box 1. When the lock core wave wheel 5.1 collides with the second extension section on the lower side of the hook tongue anti-theft insurance 5.2, the hook tongue anti-theft insurance 5.2 is driven to slide downward along the groove of the lock box 1. A third extension section is provided on the side of the hook tongue anti-theft insurance 5.2 near the rotating member 4, and the third extension section and the gear 4.1 of the rotating member 4 can produce a collision limit. When the hook tongue anti-theft insurance 5.2 is lifted upward along the lock box 1 under the action of the lock core wave wheel 5.1, the third extension section can be stuck in the middle of the tooth groove of the gear 4.1 of the rotating member 4, so that the rotation of the gear 4.1 is limited, that is, the movement of the hook tongue 4.2 is limited, and the locking ability of the lock core 5 is used to achieve the locking of the hook tongue anti-theft insurance 5.2, that is, the limited locking of the hook tongue 4.2. Therefore, through the lock core 5 and the hook tongue anti-theft insurance 5.2, the utility model has the function of locking and anti-theft.

[0022] A hook tongue anti-misoperation device 6 is also provided in the lock box 1, and the hook tongue anti-misoperation device 6 comprises: (1) a touch plate 6.1, the touch plate 6.1 extends out of the movable plate 3 and the mounting panel 2, and can drive the touch plate 6.1 to move up and down under the action of an external force; (2) a hook tongue buckle 6.2, one end of which is connected to the lock box 1 through a rotating shaft, and the other end passes through a through hole 6.1.1 of the touch plate 6.1, the hook tongue 6.2 is also provided with a hook tongue protrusion 4.3, and the top of the hook tongue buckle 6.2 is also provided with a groove 6.2.1 that cooperates with the hook tongue protrusion 4.3.

[0023] It is worth noting that: when the fan profile 7 does not touch the window profile 8, the touch plate 6.1 always extends out of the movable plate 3 and the mounting panel, and when the fan profile 7 and the window profile 8 are fully fitted, the touch plate 6.1 will be completely retracted, and the fully retracted touch plate 6.1 is completely hidden in the fan profile 7. The touch plate 6.1 is longitudinally arranged in the lock box 1, and is provided with a plurality of through grooves that match the top protrusions of the hook tongue buckle 6.2. When the touch plate 6.1 moves up and down, the through grooves of the touch plate 6.1 collide with the protrusions of the hook tongue buckle 6.2, so that the up and down movement of the touch plate 6.1 drives the rotation of the hook tongue buckle 6.2.

[0024] A limit block is arranged on the upper end of the hook tongue buckle 6.2 near the hook tongue 4.2, and a groove 6.2.1 is arranged below the limit block to cooperate with the hook tongue protrusion 4.3. When the hook tongue buckle 6.2 rotates to the lower end, the hook tongue 4.2 can rotate freely in the lock box 1 without colliding with the hook tongue anti-misoperation device 6. When the hook tongue buckle 6.2 rotates to the uppermost end, the limit block at the upper end of the hook tongue buckle 6.2 will collide with the hook tongue protrusion 4.3 to limit the position. At this time, the hook tongue 4.2 has two situations: Mode 1, when the hook tongue 4.2 rotates to the lowermost end, the hook tongue protrusion 4.3 is accommodated in the groove 6.2.1, and when the hook tongue 4.2 rotates upward, it will be blocked by the limit block at the upper end of the hook tongue buckle 6.2; Mode 2, when the hook tongue 4.2 rotates to the uppermost end, when the hook tongue 4.2 rotates downward, it will be blocked by the limit block at the upper end of the hook tongue buckle 6.2, so that the hook tongue 4.2 cannot fully rotate downward, and a part of the hook tongue 4.2 is always exposed outside the fan profile 7, so that the fan profile 7 and the frame profile 8 cannot fully fit.

[0025] Therefore, the above technical features together constitute a complete technical solution for the hook tongue anti-misoperation device 6, which prevents the operator from rotating the handle to lock when the sash profile 7 and the frame profile 8 are not fully fitted, resulting in locking failure, thereby improving the locking success rate of the sliding door and window and reducing the possibility of misoperation. Only when the operator fully fits the sash profile 7 and the frame profile 8, the touch plate 6.1 can be fully retracted, the hook tongue buckle 6.2 can be released from the limit, and the hook tongue 4.2 can be freely rotated to achieve locking. This design not only achieves the prevention of misoperation of locking, but also does not increase redundant operating steps, and realizes the activation of the hook tongue anti-misoperation device 6 while pushing and pulling the door and window.

[0026] See also Figure 5 , 6 The multi-point lock hook lock described in this embodiment is installed on the fan profile 7. When the fan profile 7 and the frame profile 8 are fully fitted, the handle can be rotated to drive the hook tongue 4.2 to rotate into the lock buckle 9 and several locking points are locked with the lock buckle 9 under the action of the gear rack. At the same time, by locking the lock core 5, the hook tongue anti-theft insurance 5.2 is stuck in the gear 4.1 of the rotating member 4 to form a locking limit, thereby realizing the locking of the entire sliding door and window.

[0027] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
