Description

Technical Field

[0001] This utility model belongs to the field of profile door and window technology, specifically relating to a plastic profile door and window with a multi-size opening limit structure. Background Technology

[0002] Plastic profile doors and windows typically refer to doors and windows made of U-PVC plastic profiles, also known as PVC doors and windows. They are made primarily of polyvinyl chloride (PVC) resin, with added stabilizers, modifiers, fillers, UV absorbers, and other additives. The material is extruded into hollow, irregularly shaped profiles, cut, and then lined with reinforcing steel ribs before being welded and assembled into doors and windows. Advantages include energy savings in profile production, reusability of recycled materials, and energy-saving insulation.

[0003] Currently, plastic profile doors and windows are widely used in the construction industry, but horizontally sliding opening styles generally have significant safety design flaws. Due to the lack of standardized limiting structures, users find it difficult to control the opening size in actual use. This not only fails to meet the balance between daily ventilation needs and safety protection, but also creates safety loopholes when the doors and windows are fully opened. The risks of accidents such as children climbing and falling objects increase significantly, and in strong winds, unlimited window sashes may shake violently, posing a risk of falling off. Utility Model Content

[0004] The purpose of this invention is to provide a plastic profile door and window with a multi-size opening limit structure, aiming to address the significant safety design flaws in horizontally sliding opening styles of plastic profile doors and windows, which are widely used in the construction industry. Due to the lack of a standardized limit structure, users find it difficult to control the opening size in actual use. This not only fails to meet the balance between daily ventilation needs and safety protection, but also creates safety loopholes when the doors and windows are fully open. The risks of accidents such as children climbing and falling objects increase significantly, and in strong winds, unlimited window sashes may shake violently, posing a risk of falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic profile door and window with a multi-size opening limit structure, comprising a window sash slidably installed in two sliding grooves of the window frame, a limit tongue being provided on the side of the two window sashes that are far apart from each other, and the other end of the limit tongue being adhered to the outer wall of the moving block.

[0006] A side post is welded to each of the two outer walls of the movable block near the other end. A tail block is welded to the outer wall of the movable block away from the limiting tongue. An adjusting rod is threaded through the center end of the tail block. A positioning block is fixedly connected to the bottom of the adjusting rod. The positioning block is pressed against the inner wall of the sliding groove of the window frame.

[0007] In order to support the bottom of one end of the moving block and improve the stability of the moving block when it moves, as a plastic profile door and window with a multi-size opening limit structure according to this utility model, preferably, a bottom column is fixedly installed near the bottom of the moving block near the end connected with the limit tongue, and a ball is movably embedded in the bottom of the bottom column, and the bottom of the ball is in movable contact with the inner wall of the sliding groove of the window frame.

[0008] In order to concentrate and push the foreign objects in the sliding groove of the window frame to one side when the moving block moves, as a plastic profile door and window with a multi-size opening limit structure of this utility model, preferably, a side block is welded to the bottom of the connecting end of the side column and the tail block, and a scraper is glued to the bottom of the two side blocks.

[0009] The scraper is made of hard rubber, and the bottom of the scraper is in contact with the inner wall of the sliding groove of the window frame.

[0010] In order to keep the moving block's trajectory in the sliding groove of the window frame constant, as a plastic profile door and window with a multi-size opening limit structure of this utility model, preferably, each of the side columns has a transverse through notch on the outer wall away from the moving block, and each notch is movably engaged with a guide strip.

[0011] Two guide strips are symmetrically installed on the inner wall of each groove, and the outer walls of the window sash near the bottom are slidably fitted onto the outer walls of the guide strips.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, adjust the adjusting rod upwards. This will move the positioning block upwards, causing it to disengage from and press against the inner wall of the window frame's sliding groove, thus securing the structure. This allows the window sash to move within the window frame's sliding groove. As the sash moves, the limiting tongue moves the moving block, which in turn moves along the guide rail's path via the side posts. Once the window sash is opened to the desired position, adjust the adjusting rod downwards to press the positioning block into the window frame's sliding groove. This fixes the limiting tongue in its adjusted position, limiting the maximum opening range of the window sash. Furthermore, this design allows for arbitrary adjustment of the adjusting rod's position as needed, enabling the window sash to meet various opening requirements and enhancing safety when the window is open.

[0021] 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.

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a plastic profile door and window with a multi-size opening limit structure, including a window sash 2 slidably installed in two sliding grooves of the window frame 1, and a limit tongue 3 is provided on the side of the two window sashes 2 that are far apart from each other, and the other end of the limit tongue 3 is attached to the outer wall of the moving block 4.

[0023] A side post 5 is welded to each of the two outer walls of the movable block 4 near the other end. A tail block 6 is welded to the outer wall of the movable block 4 away from the limiting tongue 3. An adjusting rod 7 is threaded through the center end of the tail block 6. A positioning block 71 is fixedly connected to the bottom of the adjusting rod 7. The positioning block 71 is pressed against the inner wall of the sliding groove of the window frame 1.

[0024] The adjusting rod 7 has an internal hexagonal threaded hole. When in use, the adjusting rod 7 is adjusted by using a matching hexagonal wrench. In this way, the adjusting rod 7 can drive the positioning block 71 to perform corresponding lifting and lowering operations through the threaded structure of the connection part with the tail block 6.

[0025] Preferably, a bottom post 41 is fixedly installed near the bottom of the movable block 4, which is connected to the limiting tongue 3. A ball 42 is movably fitted at the bottom of the bottom post 41, and the bottom of the ball 42 is in contact with the inner wall of the sliding groove of the window frame 1.

[0026] In actual use, when the moving block 4 moves, it will drive the bottom column 41 to move. When the bottom column 41 moves, it will cause the ball 42 to slide along the inner wall of the slide groove of the window frame 1. In this way, the moving block 4 will be more stable when it moves in the slide groove.

[0027] Preferably, a side block 53 is welded to the bottom of the connecting end of the side post 5 and the tail block 6, and a scraper 54 is glued to the bottom of the two side blocks 53.

[0028] The scraper 54 is made of hard rubber, and the bottom of the scraper 54 is in contact with the inner wall of the groove of the window frame 1.

[0029] In actual use, when the moving block 4 moves, it will drive the side block 53 to move. When the side block 53 moves, it will drive the scraper 54 to move. When the scraper 54 moves, it will push the foreign objects in the sliding groove of the window frame 1 to one side, so that the foreign objects in the sliding groove of the window frame 1 can be gathered to one side, thus facilitating later cleaning.

[0030] Preferably, each side post 5 has a transverse through notch 51 on the outer wall of the side away from the moving block 4, and each notch 51 is movably engaged with a guide strip 52;

[0031] Two guide strips 52 are symmetrically installed on the inner wall of each groove, and the outer walls of the window sash 2 near the bottom are respectively slidably fitted onto the outer walls of the guide strips 52.

[0032] In practical use, the adjusting rod 7 is pushed upwards in the vertical direction. When the adjusting rod 7 moves upwards, it drives the positioning block 71 connected to it to move upwards simultaneously. As the positioning block 71 moves upwards, the pressure between the positioning block 71 and the inner wall of the sliding groove of the window frame 1 gradually decreases until it is completely released from the squeezing state, thereby releasing the limiting constraint on the window sash 2.

[0033] At this point, the movement restriction of window sash 2 within the sliding groove of window frame 1 is lifted, and the user can push window sash 2 according to actual needs. A limiting tongue 3 is connected to the side of window sash 2. When window sash 2 moves, the limiting tongue 3 moves synchronously, driving the moving block 4 to move, thus allowing the moving block 4 to slide within the sliding groove. Side posts 5 are symmetrically distributed on both sides of the moving block 4. The side posts 5 can slide smoothly along the trajectory of guide strip 52, ensuring smooth movement of window sash 2.

[0034] Once the window sash 2 is opened to the desired position, the adjusting rod 7 needs to be operated again. Adjusting the adjusting rod 7 downwards causes the positioning block 71 to descend, re-pressing into contact with the inner wall of the sliding groove of the window frame 1. As the positioning block 71 continues to move downwards, a tight friction is formed between the bottom of the positioning block 71 and the inner wall of the sliding groove, once again establishing a stable pressing and fixing structure. At this point, the limiting tongue 3 is fixed in its current position, thereby limiting the movement range of the window sash 2 and precisely limiting the maximum opening range of the window sash 2.

[0035] This adjustment device offers significant flexibility and practicality. Its structure allows users to arbitrarily adjust the position of the adjustment rod 7 according to different usage scenarios and needs. Whether in an office setting requiring micro-ventilation or a residential environment needing large-area ventilation, the opening size of the window sash 2 can be changed by simply operating the adjustment rod 7 to meet diverse ventilation and lighting needs.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
