Description

Technical Field

[0001] This utility model relates to the field of anti-fall-off safety lock devices, and in particular to an anti-fall-off safety lock device for aluminum alloy doors and windows. Background Technology

[0002] Aluminum alloy doors and windows have become the mainstream choice for doors and windows in modern buildings due to their lightweight, high strength, corrosion resistance, and good aesthetics. They are widely used in residential and commercial buildings. However, with the increase in service life and the influence of the external environment, the safety hazards of aluminum alloy doors and windows have gradually become prominent. As the core component for opening, closing, and fixing doors and windows, the performance defects of the locking device are one of the key factors leading to this problem.

[0003] Chinese patent document CN2331743Y discloses a lower support device for aluminum alloy doors and windows, including a button, a self-locking rod, corner buckles, and latches. The self-locking rod is located at the lower end of the button and is inserted into it. Corner buckles are located on both sides of the lower end of the self-locking rod and are welded to it. A spring is located at the lower end of the self-locking rod and passes through the portion of the self-locking rod below the corner buckles. The corner buckles are inserted into the latches. In this patent document, by setting up a self-locking rod, corner buckles, springs, and latches, the self-locking rod can be fixed simply by pressing it downwards, which is convenient, quick, and highly secure. By setting up a telescopic support rod, the opening angle of the doors and windows can be increased, resulting in better ventilation and improving the practicality of the device.

[0004] The aforementioned patent documents still have the following defects in practice:

[0005] In actual use, the welded structure of the self-locking rod and the corner buckle is prone to fatigue cracking of the weld points after long-term stress, which leads to failure of the self-locking function and loss of fixing effect; the spring is exposed to the external environment for a long time and is easily corroded by rainwater, which reduces its elasticity and causes jamming or loosening of the fixation; when the door and window are opened to the maximum angle, the connection point between the support rod and the window frame is subjected to concentrated force.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1, as Figure 1 and Figure 2 As shown, an aluminum alloy door and window anti-fall safety lock device includes a transmission link assembly 2, a fixed plate assembly 1 is provided at the bottom left of the transmission link assembly 2, a slide rod 3 is provided at the bottom right of the transmission link assembly 2, a connecting shaft assembly 4 is provided at the bottom right of the slide rod 3, a second mounting base 5 is provided at the bottom of the connecting shaft assembly 4, a moving component 6 is provided at the top center of the second mounting base 5, and a constraint component 7 is fixedly connected to the top right of the second mounting base 5.

[0029] In this implementation case, tools such as a spirit level and an electric drill were prepared. The model of the electric drill was MakitaXPH07T. Several screws and a 4mm Allen wrench were also prepared.

[0030] Preparation:

[0031] First, check the appearance and condition of moving parts, and clean the track of debris; then, mark the installation position on the side of the frame and install it. Use an electric drill to install the fixing plate assembly 1 at the bottom of the window to be installed, and install the mounting base 2 5 on the window frame base. Fix it with several screws, and tighten the screws with an Allen wrench.

[0032] In this implementation case, when the window is pushed outward to open, the thrust acts on the window sash to open it. The window sash drives the fixed plate assembly 1, which is fixedly connected to it, to move. The fixed plate assembly 1 pulls the transmission linkage assembly 2, causing the transmission linkage assembly 2 to move, which in turn pushes the slide rod 3. The slide rod 3 drives the connecting shaft assembly 4 to slide on the mounting base 5. Due to the limiting effect of the moving assembly 6, the movement range of the connecting shaft assembly 4 is limited, which results in a smaller opening range of the window.

[0033] When a large opening angle is required, press and hold the moving component 6 and drag it into the inner cavity of the constraint component 7 to lock it in place. Close the window and open it again. The connecting shaft component 4 can then disengage from the mounting base 2 5 along the guide. When a small opening is required, manually move the connecting shaft component 4 towards the mounting base 2 5 to close the window. This allows the connecting shaft component 4 to return to its initial position along the guide. Open the window slightly and press the constraint component 7. The moving component 6 will return to its original position and continue to limit the connecting shaft component 4. During this process, the window sash can be opened and adjusted smoothly, and the cooperation of each component ensures a stable opening process.

[0034] Specifically, in order to achieve the purpose of guiding the installation and transmission of door and window sashes, such as Figure 2 As shown, in this embodiment, the fixing plate assembly 1 includes a mounting base 11, and mounting holes 12 are provided on both the front and rear sides of the top end of the mounting base 11. A slide rail 13 is fixedly connected to the middle of the top end of the mounting base 11.

[0035] In this implementation case, the mounting base 11 is first fixed to the pre-set installation area at the bottom of the door and window sash through the mounting hole 12 and with the help of tools and matching screws. The slide rail 13 fixedly connected to the top center of the mounting base 11 provides a sliding track for the transmission linkage assembly 2, so that the linkage can slide smoothly along the slide rail 13, which provides the foundation for the force transmission and anti-fall-off locking function when the door and window are opened and closed.

[0036] Specifically, in order to achieve the goal of stable opening and closing of doors and windows, such as Figure 3 As shown, in this embodiment, the transmission link assembly 2 includes a first transmission link 23, a first limiting slider 21 is sleeved on the left end of the first transmission link 23, and a second limiting slider 22 is sleeved on the right end of the first transmission link 23.

[0037] Furthermore, the lower part of the limiting slider 21 is located in the inner cavity of the slide rail 13, and the lower outer part of the limiting slider 22 is fitted with a slide rod 3;

[0038] In this implementation case, since the limiting slider 21 is embedded in the slide rail 13, it ensures that the slider slides smoothly in the slide rail 13 and does not disengage. The transmission link 23 is assembled with the slide rod 3 by sleeved with the limiting slider 22, so that the limiting slider 22 is stably sleeved on the outside of the slide rod 3. This provides structural support for the efficient and stable transmission between the transmission link assembly 2 and the slide rod 3 on the sash side during the subsequent opening and closing of the door and window.

[0039] Specifically, in order to ensure smooth force transmission and controllable motion trajectory, such as Figure 3 As shown, in this embodiment, the connecting shaft assembly 4 includes a guide groove 41, a fixing block 43 is fixedly connected to the left end of the guide groove 41, a sliding joint 44 is provided in the inner cavity of the guide groove 41, a connecting shaft 42 is fixedly connected to the top end of the sliding joint 44, the right part of the slide rod 3 is sleeved on the middle of the outer side of the connecting shaft 42, and two guide blocks 45 are provided at the right end of the guide groove 41.

[0040] In this implementation case, because the fixing block 43 and the guide groove 41 confine the sliding joint 44 within the inner cavity of the mounting base 5, and the right side of the slide rod 3 is sleeved on the middle of the outer side of the connecting shaft 42, when the slide rod 3 drives the connecting shaft 42 and the sliding joint 44 to move along the guide groove 41, it always maintains a stable trajectory; when the sliding joint 44 disengages, the two guide blocks 45 can provide assistance, ensuring the realization of the overall transmission function of the locking device.

[0041] Specifically, in order to facilitate the stable assembly of the mounting base 25 with structures such as window frames, such as Figure 4 As shown, in this embodiment, small holes are provided on both the left and right sides of the top of the mounting base 25;

[0042] This implementation case provides reliable basic support for the device during the implementation process.

[0043] Example 2: Based on Example 1, this example optimizes the movement and locking stability of the locking device;

[0044] Specifically, in order to achieve the above objectives, such as Figure 5 As shown, in this embodiment, the movable component 6 includes a movable housing 61. A positioning post 62 is provided in the middle of the inner cavity of the movable housing 61. The bottom end of the positioning post 62 is fixedly connected to the mounting base 5. Two connecting plates 63 are fixedly connected to both the front and rear sides of the positioning post 62. Neither of the two connecting plates 63 is connected to the bottom end of the inner cavity of the movable housing 61. A fixing block 64 is provided at the right end of the positioning post 62. The bottom end of the fixing block 64 is fixedly connected to the bottom end of the inner cavity of the movable housing 61. A locking tongue limiting block 65 is fixedly connected to the upper side of the right end of the fixing block 64. A spring 66 is provided at the right end of both connecting plates 63. The right ends of both springs 66 are fixedly connected to the right end of the inner cavity of the movable housing 61.

[0045] In this implementation case, the positioning post 62 is first fixed to the mounting base 5, and both connecting plates 63 are fixedly connected to the positioning post 62. When the moving component 6 is pressed and dragged into the inner cavity of the constraint component 7, the locking tongue limit block 65 at the right end of the fixing block 64 is stuck in the inner cavity of the constraint component 7, and the spring 66 is stretched. When the moving component 6 needs to return to its original position, the constraint component 7 is pressed, so that the locking tongue limit block 65 is no longer stuck. At the same time, the spring 66 provides elastic buffer and reset force, causing the moving outer shell 61 to spring back to the initial position.

[0046] Specifically, in order to achieve the purpose of elastically constraining key components of the locking device, such as... Figure 5 As shown, the constraint assembly 7 includes a constraint housing 71, a top post 72 is provided at the top center of the constraint housing 71, a top post base 73 is fixedly connected to the bottom of the top post 72, a side baffle 74 is provided on the left side of the top of the top post base 73, and a spring 75 is provided at the bottom of the top post base 73.

[0047] Furthermore, a groove is provided at the upper end of the side baffle 74;

[0048] In this implementation case, when the movable component 6 is dragged into the inner cavity of the constraint housing 71, the locking tongue limiting block 65 passes through the groove on the upper part of the side baffle 74 and is locked onto the side baffle 74 to fix the movable component 6. When it is necessary to restore the movable component 6 to its original position, the top column 72 is pressed down, thereby the top column base 73 compresses the second spring 75 and drives the side baffle 74 to move synchronously. The groove on the upper part of the side baffle 74 engages with the corresponding component to achieve limiting constraint, while the second spring 75 assists the top column 72 to reset and continuously elastically lock, thereby enhancing the anti-fall-off performance of the locking device and ensuring the safety of door and window use.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
