[0001] This utility model relates to the field of sliding door and window technology, and more specifically, to a pulley mechanism for sliding doors and windows. Background Technology

[0002] With the popularization of green building concepts, users have increasingly higher requirements for the versatility of door and window hardware installation. Existing sliding doors and windows on the market use a pulley mechanism assembled between the door / window sash and the track to increase the smoothness of sliding.

[0003] However, existing pulley mechanisms are highly integrated and limited by the sliding surface, which is a fixed size. The door and window sashes may be changed in size depending on different installation requirements, and the track size is not fixed. The phenomenon of mismatch between the track and the pulley mechanism often occurs, which makes the existing pulley mechanism unable to adapt to a variety of different sizes of door and window sashes.

[0004] The above shortcomings need to be improved. Utility Model Content

[0014] Furthermore, the adjusting pad includes a first limiting structure and a connecting portion. The adjusting pad is engaged with the mounting sleeve through the first limiting structure, and the connecting portion is located on the outside of the mounting sleeve.

[0015] Furthermore, each of the adjustment pads includes a connecting portion and a first limiting structure located at both ends of the connecting portion, wherein the extending direction of the first limiting structure is perpendicular to the extending direction of the connecting portion.

[0016] Furthermore, the first limiting structure includes a limiting plate, the lower end of which is provided with a hook portion and the upper end of which is provided with a protrusion.

[0047] To enable sliding doors and windows, a pulley mechanism is installed between the door / window sash and the track. However, the existing pulley mechanisms for sliding doors and windows are limited in their applicability to a single size. Therefore, this invention provides a pulley mechanism for sliding doors and windows that increases the versatility of the pulley mechanism, allowing it to adapt to doors and windows of different widths and corresponding tracks.

[0048] like Figures 1 to 18As shown, the pulley mechanism of this sliding door and window includes a pulley component 10 and mounting sleeves 20 of various widths. The pulley mechanism may also include adjusting pads 30 of various thicknesses. In practical use, the pulley component 10 can be installed alone in the sliding door and window; alternatively, mounting sleeves 20 of different widths can be used in conjunction, with the pulley component 10 mounted on the sliding track of the sliding door and window via the mounting sleeves 20; or, if a mounting sleeve 20 is selected, adjusting pads 30 of different thicknesses can be added. By utilizing different selections, pulley mechanisms of different widths can be formed, thus adapting to different installation occasions.

[0049] In this invention, the pulley component 10 includes an adjusting housing 11 and a pulley assembly 13 located within the adjusting housing 11. The adjusting housing 10 is used to install and fix the entire pulley component 10, and the pulley assembly 13 is used to realize the push-pull sliding function. The pulley component 10 also includes a clamping bracket 12 mounted on the adjusting housing 11 and an adjusting component 14 connected to the adjusting housing 11 and the clamping bracket 12 respectively to adjust the relative position of the adjusting housing 11 and the clamping bracket 12.

[0050] The sliding door and window pulley mechanism of this utility model includes various mounting sleeves 30 of different widths. The mounting sleeves 30 are fitted around the pulley component 10 and are assembled and fixed to it. Specifically, the mounting sleeves 30 are clearance-fitted with the adjusting housing 11 (i.e., the two side walls of each limiting groove 231 on the mounting sleeve 30 press against the adjusting housing 111, see below for details), and are snapped in place. The advantage of this utility model is that different mounting sleeves 30 can be selected according to different door and window sash sizes without changing the specific structure of the pulley component 10. That is, producing one model of pulley component 10 can be applied to different scenarios, increasing the versatility of the pulley component 10.

[0051] In this invention, the mounting sleeve 20 includes a top plate and side walls located on both sides of the top plate. The top plate and the two side walls are connected to form a space for the installation and sliding of the pulley component 10. The end of the mounting sleeve 20 has an opening 22 for assembling the pulley component 10, so that the pulley mechanism of the sliding door / window, assembled from mounting sleeves 20 of various sizes and the pulley component 10, can adapt to door / window sashes of different sizes. Clearly, the appropriate mounting sleeve 20 is selected according to the size of the door / window sash. In other words, the size of the mounting sleeve 20 (or the size of the selected adjusting pad 30) varies depending on the size of the door / window sash, and adaptive adjustment can be achieved without changing the structure of the pulley component 10.

[0052] The top of the adjusting housing 11 is provided with a limiting hole 1111, and the top of the mounting sleeve 20 is provided with a downwardly protruding limiting post 21. The limiting post 21 and the limiting hole 1111 are engaged with each other to achieve the assembly and fixation of the mounting sleeve 20 and the adjusting housing 11. Specifically, the adjusting housing 11 includes a mounting edge 111 extending from one end, and the limiting hole 1111 is provided on the mounting edge 111. When the end of the pulley component 10 away from the adjusting assembly extends from the opening 22 and is assembled into the mounting sleeve 20, the limiting post 21 is assembled into the limiting hole 1111, so that the pulley component 10 can be assembled into mounting sleeves 20 of different sizes and assembled into a pulley mechanism for sliding doors and windows that are adapted to different sizes of door and window sashes.

[0053] To ensure a secure connection between the pulley component 10 and the mounting sleeve 20, two mounting edges 111 extend from both ends of the top plate of the adjusting housing 11, and each mounting edge 111 has two symmetrical limiting holes 1111 about the center line of the width direction of the adjusting housing 11. The mounting sleeve 20 includes two limiting posts 21 located at both ends of the mounting sleeve 20, and each limiting post 21 is installed into the corresponding limiting hole 1111 when the pulley component 10 is installed into the mounting sleeve 20. To further ensure a secure connection between the pulley component 10 and the mounting sleeve 20, the two limiting posts 21 are located on opposite sides of the center line of the width direction of the top plate of the adjusting housing 11.

[0054] When the adjusting pad 30 is required to be used, the adjusting pad 30 is installed on at least one side of the mounting sleeve 20, and the outer side of the adjusting pad 30 protrudes from the side wall of the mounting sleeve 20. Preferably, in order to ensure the stability of the pulley mechanism 10, at least two adjusting pads 30 are distributed on both sides of the pulley mechanism 10, that is, the number of adjusting pads 30 is at least two, and the two adjusting pads 30 are the same size and are adapted to the size of the mounting sleeve 20.

[0055] To achieve the assembly of the adjusting pad, in this invention, the adjusting pad 30 is snapped into the mounting sleeve 20, thereby allowing the adjusting pad 30 to be used in conjunction with the mounting sleeve 20. In this invention, the adjusting pad 30 includes a first limiting structure 31 and a connecting portion 32, wherein the first limiting structure 31 is used to achieve the connection with the mounting sleeve 20, and the connecting portion 32 is used to be placed on the outside of the mounting sleeve 20 to form a dimensional extension.

[0056] The adjusting pad 30 is engaged with the mounting sleeve 20 via a first limiting structure 31. The side wall of the mounting sleeve 20 is provided with a second limiting structure 23. The first limiting structure 31 and the second limiting structure 23 are engaged to engage the adjusting pad 30 with the mounting sleeve 20. At least one adjusting pad 30 is assembled onto the mounting sleeve 20 in such a manner that the first limiting structure 31 and the corresponding second limiting structure 23 cooperate to clamp between the mounting sleeve 20 and the pulley component 10, thereby allowing the pulley mechanism of the sliding door and window to be assembled between door and window sashes and sliding rails of different sizes.

[0057] In the present utility model, each adjusting pad 30 includes a connecting portion 32 and first limiting structures 31 respectively located at both ends of the connecting portion 32. The extending direction of the first limiting structures 31 is perpendicular to the extending direction of the connecting portion 32. Therefore, through the mutual cooperation of the two first limiting structures 31 and the connecting portion 32, a "卄"-shaped connecting structure is formed. For one first limiting structure 31, it can make the connection between the adjusting pad 30 and the mounting sleeve 20 more stable. Correspondingly, both side portions of the mounting sleeve 20 have two second limiting structures 23 arranged at intervals, and each second limiting structure 23 includes two mounting holes 232 and limiting grooves 231 corresponding to the first limiting structures 31. Therefore, the number of adjusting pads 30 can be four, and the sizes of the four adjusting pads 30 are the same.

[0058] Specifically, the first limiting structure 31 includes a limiting plate 311. A hook portion 313 is provided at the lower end of the limiting plate 311. The limiting plate 311 is snap-connected to the mounting sleeve 20 through the hook portion 313. Correspondingly, the second limiting structure 23 includes a mounting hole 232 penetrating through the side wall of the mounting sleeve 20 and a limiting groove 231 located inside the mounting sleeve 20. The first limiting structure 31 (specifically referring to the limiting plate 311 and the hook portion 313) extends into the interior of the mounting sleeve 20 through the mounting hole 232 and is snap-connected to the limiting groove 231, so that the connecting portion 32 is located outside the mounting sleeve 20, and the limiting plate 311 is snap-connected in the limiting groove 231 to prevent the limiting plate 311 from shaking. In addition, a convex portion 312 is provided at the upper end of the limiting plate 311. The upper surface of the convex portion 312 is flush with the upper surface of the mounting sleeve 20, so that the outer surface of this pulley mechanism is smoother, which is beneficial to the stability of the structure.

[0059] In order to hook the hook portion 313 into the corresponding limiting groove 231, a stop plate 233 is provided between the mounting hole 232 and the lower surface of the mounting sleeve 20, and the length value of the stop plate 233 is less than the length value of the limiting groove 231.

[0060] In a specific embodiment, corresponding to the shape of the mounting hole 1121, the convex portion 1201a can be convex-shaped in the cross-section parallel to the top of the mounting sleeve 11.

[0061] Preferably, the mounting sleeve 20 and the adjusting pad 30 are integrally formed respectively, which increases the structural strength. In a specific embodiment, the materials of the mounting sleeve 30 and the adjusting pad 20 are both preferably nylon materials. Compared with rubber, which has low strength and is easy to age, using nylon materials for the mounting sleeve 20 and the adjusting pad 30 can ensure sufficient toughness and strength, and they are not easy to age, with a high service life.

[0062] Those skilled in the art will understand that by replacing the mounting sleeves 20 and / or adjusting pads 30 of different sizes, the pulley component 10 can be used alone for assembly, or the pulley mechanism of the sliding door and window, which can be assembled from the pulley component 10, the mounting sleeves 20 of different sizes and the adjusting pads 30 of different sizes, can be adapted to various door and window sashes of different sizes.

[0063] It should be noted that the appropriate mounting sleeve 20 and adjusting pad 30 should be selected according to the dimensions of the door / window sash. For example, the number of mounting sleeves 20 can be a single unit; the width of the mounting sleeve 20 can be 29.06 mm or 37.06 mm, and the number of adjusting pads 30 can be four; the thickness of the adjusting pad 30 can be 1 mm, 2 mm, or 3 mm. That is to say, when the width of the mounting sleeve 20 is 29.06 mm, the thickness of the adjusting pad 30 can be 1 mm, 2 mm, or 3 mm; when the width of the mounting sleeve 20 is 37.06 mm, the thickness of the adjusting pad 30 can also be 1 mm, 2 mm, or 3 mm.
