Description

Technical Field

[0001] This utility model relates to the field of limiting structure technology, and in particular to a door and window opening and closing limiting structure. Background Technology

[0002] Doors and windows, depending on their location, are classified as either enclosure components or partition components, and are an important part of the building envelope system. Glass doors and windows have high light transmittance, significantly improving indoor lighting and making spaces brighter and more open. Double-glazed windows can further reduce heat loss, resulting in significant energy savings; glass doors can enhance the aesthetics of a space through textures, patterns, and shapes; and sound insulation and noise reduction designs, such as double-glazed windows, can reduce the transmission of indoor and outdoor noise.

[0003] Doors and windows are essential components of buildings and are widely used in daily life. Regular ventilation is necessary in homes to ensure air circulation. However, children, lacking safety awareness, are prone to climbing to window frames, posing a risk of falling. Therefore, many families use window locking mechanisms to limit the opening size of windows, ensuring ventilation while preventing children from climbing out. Common window and door locking mechanisms often use screws, which are screwed directly into the window frame to restrict the opening size. However, using screws not only damages the window frame structure but also makes it difficult to change their position and disassemble them, thus hindering household needs. Utility Model Content

[0004] The purpose of this application is to provide a door and window opening and closing limiting structure to solve the problem that the common door and window opening and closing limiting structures mentioned in the background art are mostly screws, which are directly screwed into the window frame to limit the opening and closing size of the door and window. However, using screws for limiting not only damages the window frame structure, but also makes it difficult to change its position as needed and disassembly is very troublesome. Therefore, it is not conducive to the needs of household use.

[0005] To achieve the above objectives, this application provides the following technical solution: a door and window opening and closing limiting structure, including a front side plate, a rear side plate, a top plate, and three fasteners. A limiting post is fixed on the side of the front side plate near the rear side plate, and a carrier tube and two fixing tubes are fixed on the side of the rear side plate near the front side plate. The limiting post slides with the inner wall of the carrier tube. A plurality of first through holes are provided on the top plate in a linear arrangement. One of the fasteners is used to fix the front side plate and the top plate, and the other two fasteners are used to fix the front side plate and the rear side plate. The two fasteners are threadedly connected to the two fixing tubes respectively.

[0006] Furthermore, the carrier tube and the two fixed tubes are arranged in a triangular configuration.

[0007] Furthermore, the front panel includes a U-shaped plate, a first vertical plate is fixed to the top of the U-shaped plate, a second vertical plate is fixed to the bottom of the U-shaped plate, and a second through hole is provided on the U-shaped plate for fasteners to pass through, with the two second through holes corresponding to two fixing tubes respectively.

[0008] Furthermore, the top of the U-shaped plate is provided with a threaded hole, and the fastener passes through the corresponding first through hole and is threadedly connected to the threaded hole.

[0009] Furthermore, the fastener consists of a knob and a stud, with one end of the stud fixedly mounted on the knob.

[0010] Furthermore, a magnet is fixed inside the carrier tube, and an iron block is fixed at the other end of the limiting post. A guide groove is opened at the other end of the iron block, and the magnet is used to magnetically attract the iron block.

[0011] In summary, the technical effects and advantages of this utility model are as follows: In this invention, two fasteners are used to fix the front side plate and the rear side plate, so that the front side plate and the rear side plate are respectively stuck on both sides of the door and window sliding track. The limiting post on the front side plate can be inserted into the carrier tube on the rear side plate after passing through the drainage hole opened in the door and window sliding track. The limiting post and the carrier tube can be stuck inside the drainage hole of the sliding track. In this way, the opening and closing of the door and window can be limited. It is not only convenient to install and remove, but also will not cause irreversible damage to the door and window structure.

[0012] In this invention, fasteners can be used to fix the top plate to the front side plate. The top plate has several first through holes arranged in a linear pattern. This allows the fixed position of the top plate on the front side plate to be adjusted as needed, so that the top plate, in conjunction with the front side plate, can adjust the control of the opening and closing size of the doors and windows, thus better meeting the needs of users.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: Reference Figure 1-5 The illustrated door / window opening and closing limiting structure includes a front panel 1, a rear panel 2, a top panel 3, and three fasteners 9. A limiting post 4 is fixed to the side of the front panel 1 closest to the rear panel 2. A carrier tube 5 and two fixing tubes 6 are fixed to the side of the rear panel 2 closest to the front panel 1. The carrier tube 5 and the two fixing tubes 6 are arranged in a triangular configuration. This arrangement makes the overall structure more stable and the force distribution more balanced when the front panel 1 and the rear panel 2 are fixed. The limiting post 4 slides against the inner wall of the carrier tube 5. A linear fastener 9 is provided on the top panel 3. Multiple first through holes 7 are arranged in a row. One fastener 9 is used to fix the front side plate 1 and the top plate 3. The top plate 3 can be fixed to the front side plate 1 by using the fastener 9. Multiple first through holes 7 are arranged in a linear manner on the top plate 3. This allows the fixing position of the top plate 3 on the front side plate 1 to be adjusted as needed, so that the top plate 3 can be adjusted to control the opening and closing size of the door and window in conjunction with the front side plate 1. The other two fasteners 9 are used to fix the front side plate 1 and the rear side plate 2, and the two fasteners 9 are respectively threaded to the two fixing pipes 6. The front side plate 1 and the rear side plate 2 are fixed by two fasteners 9, so that the front side plate 1 and the rear side plate 2 are respectively stuck on both sides of the door and window slide rail. The limiting post 4 on the front side plate 1 can be inserted into the carrier tube 5 on the rear side plate 2 after passing through the drainage hole opened in the door and window slide rail. The limiting post 4 and the carrier tube 5 can be stuck inside the drainage hole of the slide rail. In this way, the opening and closing of the door and window can be limited.

[0018] The front panel 1 includes a U-shaped plate 101. A first vertical plate 102 is fixed to the top of the U-shaped plate 101, and a second vertical plate 103 is fixed to the bottom of the U-shaped plate 101. A second through hole 8 is provided on the U-shaped plate 101 for the fastener 9 to pass through. The two second through holes 8 correspond to two fixing tubes 6 respectively. A threaded hole 10 is provided on the top of the U-shaped plate 101. After the fastener 9 passes through the corresponding first through hole 7, it is threadedly connected to the threaded hole 10. Fastener 9 consists of a knob 901 and a stud 902, with one end of the stud 902 fixedly mounted on the knob 901.

[0019] The carrier tube 5 has a magnet 12 fixed inside, and the other end of the limiting post 4 has an iron block 11 fixed. The other end of the iron block 11 has a guide groove to facilitate the insertion of the iron block 11 into the carrier tube 5. The magnet 12 is used to magnetically attract the iron block 11. With the help of the iron block 11 and the magnet 12, the front side plate 1 and the rear side plate 2 can be temporarily kept in a stable position after they are connected, which facilitates the subsequent installation of the two fasteners 9.

[0020] Working principle of this utility model: In use, remove all components of the device, clip the front side plate 1 onto one side of the window frame slide rail, and clip the rear side plate 2 onto the other side of the slide rail. The limiting post 4 on the front side plate 1 passes through the drainage hole opened in the window frame slide rail and is then inserted into the inside of the carrier tube 5. The magnet 12 magnetically attracts the iron block 11, so that the front side plate 1 and the rear side plate 2 can temporarily maintain their position when clipped onto both sides of the slide rail. Take out the two fasteners 9 and pass them through the two second through holes 8 respectively, so that the fasteners 9 are screwed into the inside of the fixing tube 6. In this way, the two fasteners 9 can fix the front side plate 1 and the rear side plate 2 on the window frame slide rail. At this time, due to the influence of the length of the drainage hole, the front side plate 1 and the rear side plate 2 have a small range of movement on the slide rail. Remove the top plate 3 and place it on the front side plate 1. The user aligns the designated first through hole 7 on the top plate 3 with the threaded hole 10 according to their own needs. Remove the last fastener 9 and fix the front side plate 1 and the top plate 3. The user slides the window to push the top plate 3, thereby pushing the front side plate 1 and the rear side plate 2, so that the limiting post 4 and the carrier pipe 5 are against the farthest end of the drain hole. After that, the window cannot be pushed any further, thus achieving the limitation and control of the window opening size.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
