Description

Technical Field

[0001] This utility model relates to the field of window lock technology, specifically an automatic locking window lock. Background Technology

[0002] A window lock is a device used to secure windows, primarily installed on the edge of the window to prevent it from being opened or damaged. Window locks come in a variety of designs and functions and are suitable for different types of windows, such as sliding windows and casement windows.

[0003] Traditional window locking devices mostly rely on manual operation, such as rotary handles, latches, or bolt structures. Users need to actively complete the locking action. Manual locking requires users to apply additional force and accurately remember the locking steps. In a hurry or if they are careless, the lock may be missed, leaving the window in an unsafe state. At the same time, frequent operation can cause wear and tear on mechanical parts (such as threads and hinges), reducing their service life. In addition, some existing automatic window locks use electromagnetic drives or electronic sensors. Although they can achieve self-locking upon closure, they have problems such as complex structure, dependence on external power supply, and high maintenance costs. Furthermore, the circuit system is prone to failure in humid environments, limiting the applicable scenarios. Therefore, an automatic locking window lock is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatically locking window lock to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatically locking window lock, including a panel,

[0006] The upper end of the panel is provided with a movable groove, the bottom end of the movable groove is provided with a plurality of first rectangular sliding grooves, the upper left end of the movable groove is fixedly connected to a limiting plate, and a locking box is provided at one horizontal end of the panel.

[0007] Furthermore, a handle is slidably connected to the middle of the movable groove, and an L-shaped limiting rod is fixedly connected to the lower front and rear ends of the handle. The L-shaped limiting rod passes through the first rectangular sliding groove.

[0008] Furthermore, a first limiting rod is welded to the lower end of the handle. The first limiting rod passes through the first rectangular slide groove, and the handle, the L-shaped limiting rod, and the first limiting rod are all slidably connected to the first rectangular slide groove from left to right.

[0009] Furthermore, a lock box is provided on the left side of the panel, and a lock tongue is slidably connected to the middle of the lock box.

[0010] Furthermore, a first return spring is fixedly connected to the bottom end of the latch, and one end of the first return spring is fixedly connected to the inner wall of the lock box.

[0011] Furthermore, a second limiting rod is provided at the middle of the left end of the first reset spring, and one end of the second limiting rod is fixedly connected to the inner wall of the lock box.

[0012] Furthermore, the top of the locking tongue is provided with several slots, and the first limiting rod passes through the slots.

[0013] Furthermore, the bottom of the lock box is provided with several second rectangular sliding grooves, and several third limiting rods are slidably connected in the middle of the second rectangular sliding grooves. One end of each third limiting rod is fixedly connected to the lock tongue.

[0014] Furthermore, a limiting pad is welded to the rear end of the inner wall of the lock box, an elastic lever is fixedly connected to the rear end of the inner wall of the lock box, and a locking block is fixedly connected to the bottom end of the lock tongue. The locking block and the limiting pad are engaged.

[0015] Furthermore, a second return spring is fixedly connected to the left end of the inner wall of the lock box, and a moving rod is fixedly connected to one end of the second return spring. The moving rod passes through the lock tongue and is slidably connected to the lock tongue from left to right.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting up a handle, a first limiting rod, an elastic lever, and a locking block, pushing the handle to the left moves the locking block at the lower end of the latch to the left end of the elastic lever. The elastic lever engages with the locking block, which helps to fix the latch. This, in turn, drives the latch to reset, enabling the window to unlock quickly. This simplifies the complex operation steps of traditional window locks and significantly improves the efficiency of opening and closing windows. By setting up a first reset spring, latch, locking block, and limiting pad, the latch automatically moves to the right due to the elastic force of the first reset spring. With the engagement of the locking block and the limiting pad, the window locks itself automatically locks itself the moment it closes. This design eliminates the need for manual intervention in the locking action, effectively preventing security risks caused by forgetting to lock the window. The flexible lever and moving rod work together to create a double safety mechanism: when the window is closed and the moving rod is triggered, the flexible lever is pressed and releases the locking block, ensuring the bolt only pops out when fully closed. This design effectively prevents accidental unlocking caused by external impacts or vibrations. The L-shaped limit rod and the first rectangular groove ensure precise handle movement, preventing mechanical jamming caused by deviation. The second limit rod maintains consistent spring return direction, improving bolt movement reliability. The third limit rod and the rectangular groove enhance bolt sliding smoothness and extend service life. This multi-level limit system works synergistically to significantly reduce component wear risks. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides an automatic locking window lock solution: An automatic locking window lock includes a panel 1. The upper end of the panel 1 has a moving groove 2, and the bottom end of the moving groove 2 has several first rectangular sliding grooves 3. A limiting plate 4 is fixedly connected to the upper left end of the moving groove 2. A latch box 20 is provided at one horizontally corresponding end of the panel 1. A handle 5 is slidably connected to the middle of the moving groove 2. By setting the handle 5, first limiting rod 7, elastic lever 16, and locking block 17, pushing the handle 5 to the left moves the locking block 17 at the lower end of the latch 9 to the left end of the elastic lever 16. The elastic lever 16 engages with the locking block 17, facilitating the fixing of the latch 9. This, in turn, drives the latch 9 to reset, enabling rapid window unlocking. This simplifies the complex operation steps of traditional window locks and significantly improves the efficiency of opening and closing windows. The handle 5... L-shaped limiting rods 6 are fixedly connected to the lower front and rear ends. By setting the L-shaped limiting rods 6 and the first rectangular slide groove 3, the movement trajectory of the handle 5 is ensured to be accurate, avoiding mechanical jamming caused by deviation. The L-shaped limiting rods 6 pass through the first rectangular slide groove 3. The lower end of the handle 5 is welded with a first limiting rod 7, which also passes through the first rectangular slide groove 3. The handle 5, L-shaped limiting rods 6 and first limiting rods 7 are all slidably connected to the first rectangular slide groove 3. A lock box 8 is opened on the left side of the panel 1. A lock tongue 9 is slidably connected in the middle of the lock box 8. A first return spring 10 is fixedly connected to the bottom end of the lock tongue 9. By setting the first return spring 10, lock tongue 9, locking block 17 and limiting pad 15, the lock tongue 9 automatically moves to the right by the elastic force of the first return spring 10. With the locking of the locking block 17 and the limiting pad 15, the self-locking is completed at the moment the window is closed. This design eliminates the need for manual intervention in the locking action, effectively preventing security risks caused by forgetting to lock the device. One end of the first return spring 10 is fixedly connected to the inner wall of the lock box 8.

[0030] A second limiting rod 11 is provided at the middle of the left end of the first return spring 10. By setting the second limiting rod 11, the spring's rebound direction is kept consistent, improving the reliability of the lock tongue 9's movement. One end of the second limiting rod 11 is fixedly connected to the inner wall of the lock box 8. Several slots 12 are provided at the top of the lock tongue 9, through which the first limiting rod 7 passes. Several second rectangular sliding grooves 13 are provided at the bottom of the lock box 8. Several third limiting rods 14 are slidably connected in the middle of the second rectangular sliding grooves 13. By setting the third limiting rods 14 and the rectangular sliding grooves, the sliding stability of the lock tongue 9 is enhanced, extending its service life. The multi-level limiting system works synergistically, significantly reducing the risk of component wear. One end of the third limiting rod 14 is fixedly connected to the lock tongue 9. A limiting pad 15 is welded to the rear end of the inner wall. An elastic lever 16 is fixedly connected to the rear end of the inner wall of the lock box 8. By setting the elastic lever 16 and the moving rod 19, the linkage mechanism of the elastic lever 16 and the moving rod 19 forms a double insurance: when the window is closed and the moving rod 19 is triggered, the elastic lever 16 is pressed and releases the locking block 17, ensuring that the lock tongue 9 only pops out in the fully closed state. This design effectively prevents accidental unlocking caused by external impact or vibration. The bottom end of the lock tongue 9 is fixedly connected to the locking block 17, which is engaged with the limiting pad 15. The left end of the inner wall of the lock box 8 is fixedly connected to the second return spring 18, and one end of the second return spring 18 is fixedly connected to the moving rod 19. The moving rod 19 passes through the lock tongue 9 and is slidably connected to the lock tongue 9.

[0031] The unlocking operation procedure of this utility model is as follows:

[0032] 1. Manual Unlocking: When the window needs to be opened, the user pushes the handle 5 to the left, causing the first limiting rod 7 welded to its lower end to move to the left along the first rectangular slide groove 3. The first limiting rod 7 synchronously drives the latch 9 to slide to the left against the elastic force of the first return spring 10, so that the latch 9 is completely disengaged from the strike box 20, releasing the locked state.

[0033] Limit protection: When the L-shaped limit rod 6 moves with the handle 5, it precisely limits the movement along the first rectangular slide groove 3 to prevent the handle 5 from deviating; the third limit rod 14 slides within the second rectangular slide groove 13 to ensure the stability of the horizontal movement trajectory of the locking tongue 9 and avoid jamming.

[0034] 2. Automatic locking triggered when the window sash is closed.

[0035] Motion lever triggering mechanism: When the window sash is closed, the motion lever 19 inside the latch box 20 is pressed to the left by the window frame, compressing the second return spring 18. When the motion lever 19 moves to the left limit position, its end presses against the elastic tab 16 and bends downward.

[0036] Locking block release and latch ejection: After the elastic lever 16 is pressed down, the limiting constraint on the locking block 17 at the bottom of the latch 9 is released. Under the elastic force of the first return spring 10, the latch 9 quickly moves to the right and inserts into the corresponding slot of the latch box 20, completing the automatic locking.

[0037] Locking status maintenance: After the bolt 9 moves to the right and reaches its position, the locking block 17 engages with the limiting pad 15 inside the lock box 8, restricting further movement of the bolt 9; the elastic lever 16 resets and presses against the locking block 17, forming a double locking safety to prevent accidental unlocking caused by external vibration.

[0038] 3. Synergistic effect of core components

[0039] Spring system:

[0040] First return spring 10: drives the locking tongue 9 to move to the right to achieve automatic locking;

[0041] Second reset spring 18: pushes the moving rod 19 to reset, storing energy for the next trigger.

[0042] Limiting structure:

[0043] L-shaped limit rod 6 and slide groove: constrain the stroke of handle 5 to ensure operational accuracy;

[0044] The third limiting rod 14 and the second rectangular slide groove 13: maintain the sliding stability of the locking tongue 9;

[0045] Limiting pad 15 and locking block 17: limit the maximum displacement of locking tongue 9 to prevent overload;

[0046] 4. Safety and Durability Design

[0047] Anti-accidental activation mechanism: The elastic lever 16 will only release the locking block 17 when the window sash is fully closed and the lever 19 is pressed to the limit position, ensuring that the locking action is strictly synchronized with the window sash closing state and eliminating the risk of false locking.

[0048] Wear-resistant design: The locking tongue 9 and the locking box 20 use hard alloy contact surfaces to reduce long-term friction wear; all slides 3 and 13 are embedded with lubricating bushings to reduce movement resistance.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
