Description
Technical Field
[0001] This utility model relates to the field of door and window hook technology, and in particular to a narrow-edge sliding door and window hook mechanism. Background Technology
[0002] The hook and latch mechanism is the core component connecting the movable and fixed sashes in sliding doors and windows. It is mainly located on the vertical side of the movable sash and corresponds to the edge latch of the fixed sash. Its main body is mostly made of aluminum alloy, which combines strength and weather resistance. The side usually has a pre-reserved sealing groove to embed EPDM rubber strips, thereby blocking air and rainwater penetration and improving the sound and heat insulation of the doors and windows. At the same time, the hook and latch mechanism, through precise size design, can ensure that the movable sash slides smoothly without jamming, and can also help position the sash body to avoid deviation. It is not only a guarantee for the opening function of the door and window, but also a key carrier of sealing performance, which directly affects the user experience and durability of sliding doors and windows.
[0003] In the hook and pull structure of sliding doors and windows, the rollers below the hook and pull are the core guiding components that bear the weight of the sash and enable smooth sliding. The precision of their fit with the track directly determines the opening and closing performance of the door and window. Currently, most rollers are fixed in the bottom slot of the hook and pull by snap-on or one-piece injection molding. Although the initial assembly is convenient, in long-term use, the weight of the sash continuously acts on the rollers, which can easily lead to wear of the roller rubber material and deformation of the metal bracket. This reduces the fit between the roller and the track, and significantly increases the friction. With the increase in friction, the rollers are prone to lateral displacement, causing the door and window to slide and pull, making abnormal noises, and even causing the hook and pull to misalign with the sealing strip of the frame, reducing the sound and heat insulation effect of the door and window. More importantly, the existing fixing structure lacks a convenient disassembly design. If it is necessary to adjust the position of the rollers or replace worn parts, the entire hook and pull structure must be disassembled, which is cumbersome and can easily damage the hook and pull body, making it difficult to meet the daily maintenance needs of users.
[0004] Therefore, it is necessary to invent a narrow-edge sliding door and window hook mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a narrow-edge sliding door and window hook mechanism to solve the problem mentioned in the background art. In the sliding door and window hook structure, the roller below the hook is the core guiding component that bears the weight of the sash and enables smooth sliding. The accuracy of its fit with the track directly determines the opening and closing performance of the door and window. Existing rollers are mostly fixed in the bottom groove of the hook by snap-on or one-piece injection molding. Although the initial assembly is convenient, in long-term use, the weight of the sash continuously acts on the roller, which easily leads to wear of the roller's rubber material and deformation of the metal bracket. This reduces the fit between the roller and the track, significantly increases friction, and with the increased friction, the roller is prone to lateral displacement, causing the door and window to slide and make noise, and even causing the hook and frame sealing strip to misalign, reducing the sound and heat insulation effect of the door and window. More importantly, the existing fixing structure lacks a convenient disassembly design. If it is necessary to adjust the position of the roller or replace worn parts, the entire hook structure must be disassembled, which is cumbersome and easily damages the hook body, making it difficult to meet the user's daily maintenance needs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hook mechanism for narrow-edge sliding doors and windows, including a hook mechanism body, a glass panel on the inner side of the hook mechanism body, an outer frame on the outer side of the hook mechanism body, sliders at both the upper and lower ends of the hook mechanism body, a fixing block fixedly connected to one side of the slider, and an adjusting bolt threadedly connected to the inner side of the fixing block. The slider has a groove on its side, and a movable block is slidably connected to the inside of the groove. The movable block is located at the bottom of the fixed block, and the end of the adjusting bolt is rotatably located inside the movable block. A limit plate is fixedly connected to the side of the movable block, and the limit plate is located inside the slider.
[0007] As a preferred embodiment, sound-absorbing cotton is provided on both sides of the slider, a connecting block is fixedly connected to the top of the slider, a limit block is fixedly connected to the top of the connecting block, and the connecting block and the limit block are slidably connected to the inner side of the hook mechanism body.
[0008] As a preferred embodiment, a mounting plate is fixedly connected to the side of the limiting block, and a fastening bolt is provided on the inner side of the mounting plate. The mounting plate is fixedly connected to the side of the hook mechanism body by the fastening bolt.
[0009] As a preferred embodiment, the bottom end of the slider is provided with a roller, the outer side of the roller is provided with a silencing ring, and the top end of the roller is provided with a top plate.
[0010] As a preferred embodiment, side plates are fixedly connected to both sides of the top plate, the silencing ring is rotatably connected between the two side plates, and a limit rod is fixedly connected to the outer side of the side plate.
[0011] As a preferred embodiment, the top and bottom ends of the outer frame are symmetrically provided with side limiting edges, and a sliding groove is provided between the two side limiting edges, with the slider slidably connected to the inner side of the sliding groove.
[0012] The technical effects and advantages of this utility model are as follows: This utility model features symmetrical sliders at both ends of the hook mechanism body, with rollers at the bottom of the sliders. Adjustable bolts, fixing blocks, and moving blocks on the sides of the sliders effectively move the internal limiting plate, thereby changing the roller's operating height. This allows for adjustment and control of the roller's position after prolonged use due to pressure, by adjusting the internal limiting plate. This significantly improves the roller's lifespan. Furthermore, the sliders are easy to disassemble, facilitating roller adjustment or replacement and enhancing usability. This invention features a top plate at the top of the roller, with side plates symmetrically fixed to both sides of the bottom of the top plate, allowing the roller to rotatably connect between the two rollers. A limit rod is fixedly connected to the outer side of the side plate, and a groove corresponding to the top plate and the limit rod is provided on the inner side of the slider, allowing it to move up and down within the groove and effectively limiting the position of the top plate and the limit rod, thus significantly improving the stability of the roller during use.

[0015] 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.
[0016] Please see the appendix Figure 1 - Appendix Figure 4 A hook-and-loop mechanism for narrow-edge sliding doors and windows includes a hook-and-loop mechanism body 1. The hook-and-loop mechanism body 1 is the core connection and sealing component of the sliding door and window, mainly used to connect the movable door leaf with the fixed frame or adjacent movable door leaf. It has a precise hook-and-loop structure, which can make the door leaf stably positioned when it is opened and slid, avoiding displacement. At the same time, it can be used with sealing strips to greatly improve the water tightness and air tightness of the door and window, reduce wind and rain leakage and noise transmission. The material is mostly aluminum alloy and other profiles, which are adapted to the overall structure of the door and window, and directly affect the smoothness of use and sealing performance of the sliding door and window. The hook-and-loop mechanism body 1 is a component well known in this field, and will not be described in detail here. A glass 11 is provided on the inner side of the hook-and-loop mechanism body 1, and an outer frame 2 is provided on the outer side of the hook-and-loop mechanism body 1. A slider 3 is provided at both the upper and lower ends of the hook-and-loop mechanism body 1. A fixing block 38 is fixedly connected to one side of the slider 3, and an adjusting bolt 37 is threadedly connected to the inner side of the fixing block 38. The slider 3 has a groove 36 on its side, and a moving block 39 is slidably connected to the inside of the groove 36. The moving block 39 is located at the bottom of the fixed block 38, and the end of the adjusting bolt 37 is rotatably located inside the moving block 39. A limiting plate is fixedly connected to the side of the moving block 39, and the limiting plate is located inside the slider 3.
[0017] Specifically, by symmetrically arranging sliders 3 at the upper and lower ends of the hook mechanism body 1, and a roller 4 at the bottom of the slider 3, the side of the slider 3, through the setting of adjusting bolts 37, fixing blocks 38, and moving blocks 39, can effectively drive the limiting plate set inside the slider 3 to move, thereby effectively changing the working height of the roller 4. This allows the roller 4 to be adjusted and controlled by adjusting the limiting plate inside the slider 3 after long-term use due to pressure, effectively improving the service life of the roller 4. Simultaneously, the slider 3 is easy to disassemble, facilitating the adjustment or replacement of the roller 4, improving the usage effect. By setting a limiting plate at the end of the moving block 39, and providing a groove corresponding to the limiting plate on the inner side of the slider 3, the limiting plate can be slidably connected to the inner side of the slider 3. By adjusting the position of the moving block 39, the height of the limiting plate in the slider 3 can be adjusted. When the roller 4 shifts under pressure, the position of the moving block 39 can be adjusted to adjust the working height of the roller 4, ensuring that the roller 4 always rolls in a suitable position in the slide groove 22, effectively improving the usage effect.
[0018] Please see the appendix Figure 3 Both sides of the slider 3 are provided with sound-absorbing cotton 31. The top of the slider 3 is fixedly connected to a connecting block 32. The top of the connecting block 32 is fixedly connected to a limiting block 33. The connecting block 32 and the limiting block 33 are slidably connected to the inner side of the hook mechanism body 1.
[0019] Specifically, by providing sound-absorbing cotton 31 on both sides of the slider 3, when the slider 3 slides inside the groove 22, the sound-absorbing cotton 31 contacts the side wall of the groove 22, effectively reducing the noise generated by the slider 3. A connecting block 32 is fixedly connected to the top of the slider 3, and a limiting block 33 is fixedly connected to the top of the connecting block 32. Both the connecting block 32 and the limiting block 33 are slidably connected to the inside of the hook mechanism body 1. The inside of the hook mechanism body 1 is provided with grooves corresponding to the connecting block 32 and the limiting block 33, so that the connecting block 32 and the limiting block 33 can be slidably limited to the inside of the hook mechanism body 1, which facilitates the limiting and locking of the connecting block 32 and the limiting block 33 and improves the stability of the slider 3 in use.
[0020] Please see the appendix Figure 3 The side of the limiting block 33 is fixedly connected to the mounting plate 34, and the inner side of the mounting plate 34 is provided with fastening bolts 35. The mounting plate 34 is fixedly connected to the side of the hook mechanism body 1 by the fastening bolts 35.
[0021] Specifically, an mounting plate 34 is fixedly connected to the side of the limiting block 33, and a fastening bolt 35 is provided on the inner side of the mounting plate 34. The mounting plate 34 is fixedly connected to the side of the hook mechanism body 1 by the fastening bolt 35. After the connecting block 32 and the limiting block 33 are slidably limited to the inner side of the hook mechanism body 1, the mounting plate 34 can be set on the side of the hook mechanism body 1. The mounting plate 34 is fixedly connected to the outer side of the hook mechanism body 1 by the fastening bolt 35. At the same time, the connecting block 32 and the limiting block 33 are fixedly connected to the inner side of the hook mechanism body 1. This facilitates the disassembly of the mounting plate 34, the sliding of the limiting block 33 and the connecting block 32 from the inner side of the hook mechanism body 1, and the removal of the slider 3 for maintenance or replacement of the roller 4.
[0022] Please see the appendix Figure 3 and Figure 4 The bottom of the slider 3 is provided with a roller 4, the outer side of the roller 4 is provided with a silent ring 41, the top of the roller 4 is provided with a top plate 43, and the two sides of the top plate 43 are fixedly connected with side plates 42. The silent ring 41 is rotatably connected between the two side plates 42, and the outer side of the side plate 42 is fixedly connected with a limit rod 44.
[0023] Specifically, by providing a roller 4 at the bottom of the slider 3, and a silent ring 41 on the outer side of the roller 4, the roller 4 can roll on the inner side of the slide groove 22, making the movement of the hook mechanism body 1 more convenient. At the same time, the silent ring 41 can effectively reduce the generation of noise. A top plate 43 is provided at the top of the roller 4, and side plates 42 are fixedly connected to both sides of the top plate 43. The silent ring 41 is rotatably connected between the two side plates 42. A limit rod 44 is fixedly connected to the outer side of the side plate 42. A groove corresponding to the top plate 43 and the limit rod 44 is opened on the inner side of the bottom of the slider 3, so that the top plate 43 and the limit rod 44 can slide and be connected to the inner side of the slider 3, and are limited to the inner side of the slider 3, which improves the stability of the roller 4.
[0024] Please see the appendix Figure 4 The top and bottom of the outer frame 2 are symmetrically provided with side limiting edges 21, and a sliding groove 22 is provided between the two side limiting edges 21. The slider 3 is slidably connected to the inner side of the sliding groove 22.
[0025] Specifically, side limiting edges 21 are symmetrically provided at the top and bottom of the outer frame 2, and a sliding groove 22 is provided between the two side limiting edges 21. The slider 3 is slidably connected to the inner side of the sliding groove 22, thereby allowing the slider 3 to be slidably connected to the inner side of the sliding groove 22, effectively limiting the movement of the slider 3.
[0026] The working principle of this utility model is as follows: In specific use, a slider 3 is set, which can be slidably connected to the inner side of the slide groove 22. By setting sound-absorbing cotton 31 on both sides of the slider 3, when the slider 3 slides on the inner side of the slide groove 22, the sound-absorbing cotton 31 contacts the side wall of the slide groove 22, effectively reducing the noise generated by the slider 3. By setting a roller 4 at the bottom of the slider 3, and setting a silent ring 41 on the outer side of the roller 4, the roller 4 can roll on the inner side of the slide groove 22, making the movement of the hook mechanism body 1 more convenient. At the same time, setting the silent ring 41 can effectively reduce the generation of noise. When roller 4 shifts, the fastening bolt 35 can be unscrewed, and the limiting block 33 and connecting block 32 can be pulled out from the inside of the hook mechanism body 1. Then, the adjusting bolt 37 can be rotated to move the moving block 39, thereby moving the limiting plate. The limiting plate is correspondingly set with the top plate 43. The movement of the limiting plate can effectively push the top plate 43 to move, thereby effectively adjusting the working height of roller 4 so that it can match the depth of the slide groove 22. After the adjustment is completed, the connecting block 32 and the limiting block 33 can be slid into the inside of the hook mechanism body 1 and fixed again. When roller 4 is damaged, roller 4 can be slid out from the bottom of the slider 3 and a new roller 4 can be replaced.
[0027] 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.
