Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically to a multi-row push-pull side-pressure pulley assembly and door and window system. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Doors and windows can be categorized into sliding, casement, and lift-type opening and closing mechanisms. Sliding doors and windows, due to their inherent sliding structure, often suffer from poor sealing, making them unsuitable for environments with high requirements. To address this, some sliding doors and windows with side-pressure sealing have emerged on the market. After sliding closed, these doors and windows can be gradually moved laterally towards the door frame by rotating the handle, and the sealing strip on the door or window presses firmly against the frame, thus improving the sealing performance when closed.

[0004] To achieve the sliding and lateral pressure of the door and window body, a sliding and lateral pressure pulley assembly needs to be installed at the bottom of the door and window body. Existing sliding and lateral pressure pulley assemblies typically use a single-row structure for the guide pulleys that slide on the lower track of the door frame; that is, multiple guide pulleys are arranged in pairs in a straight line on the left and right sides of the lateral sliding pulley assembly. Because this guide pulley assembly only has a single row of load-bearing surfaces, when the sliding door and window are large in size and weight, instability can easily occur during sliding and load-bearing processes, causing wear on the pulley assembly and significantly shortening its service life. Utility Model Content

[0005] In order to overcome the defects mentioned above in the prior art, this utility model provides a multi-row push-pull side-pressure pulley assembly and a door and window system to solve the problem of instability of single-row pulley groups during sliding and load-bearing processes mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A multi-row push-pull side-pressure pulley assembly includes:

[0008] Side-shifting pulley assembly, which is installed at the bottom of the door / window body to achieve lateral movement of the door / window body;

[0009] Pulley plates are arranged in pairs at intervals on the front and rear sides of the lateral pulley assembly;

[0010] A guide pulley assembly is clamped and movably connected between the two pulley plates and arranged in pairs at intervals on the left and right sides of the lateral pulley assembly; the guide pulley assembly includes at least two first guide pulleys arranged side by side in the front-back direction; the first guide pulleys are used to slide on the lower track of the door frame;

[0011] An elastic component, corresponding in number to the guide pulley assembly, includes a mounting base clamped and fixedly connected between two pulley plates, a shock-absorbing frame connected to the guide pulley assembly and rotatably sleeved on the outer side of the two pulley plates, and an elastic element connected to the mounting base and the shock-absorbing frame respectively; when the pressure applied by the door / window body to the guide pulley assembly is greater than the initial tension of the elastic element, the elastic element deforms and the guide pulley assembly moves up and down relative to the pulley plates to achieve balance.

[0012] Furthermore, it also includes a fixing pin that passes through the guide pulley assembly, and a positioning hole is provided on the pulley plate. The two ends of the fixing pin pass through the two positioning holes respectively to be movably connected to the pulley plate; the shock absorber is connected to the two ends of the fixing pin to realize the connection with the guide pulley assembly.

[0013] Furthermore, the positioning hole is a vertically arranged, elongated, waist-shaped hole.

[0014] Furthermore, the shock absorber frame has a locking hole, and the pulley plate has a locking block. The shock absorber frame is fitted onto the locking block through the locking hole to achieve a rotatable connection.

[0015] Furthermore, the elastic element is a return spring.

[0016] Furthermore, the side-moving pulley assembly includes a sliding seat installed at the bottom of the door / window body, a pulley frame that slidably engages with the sliding seat, and a slider that slidably passes through the sliding seat and is drivenly engaged with the pulley frame. The slider is used to drively connect with a transmission bar. The pulley frame is provided with a second guide pulley, the central axis of the second guide pulley being perpendicular to the central axis of the first guide pulley. The pulley plates are arranged in pairs at intervals on the front and rear sides of the pulley frame, and the guide pulleys are arranged in pairs at intervals on the left and right sides of the pulley frame.

[0017] When the transmission bar is slid to drive the slider to slide on the sliding seat, it can drive the sliding seat to move laterally relative to the pulley frame through its transmission cooperation with the pulley frame, thereby driving the door and window body to move laterally and press the second guide pulley.

[0018] Furthermore, it also includes a drive shaft passing through the slider, and the pulley frame has a curved groove, wherein:

[0019] One end of the drive shaft is connected to the transmission bar, and the other end of the drive shaft extends into the curved groove and engages with it in a sliding fit.

[0020] When the transmission bar is slidable and the slider is moved on the sliding seat by the drive shaft, the sliding seat can be moved laterally relative to the pulley frame by the snap-fit ​​and sliding engagement of the drive shaft and the curved groove, thereby realizing the lateral movement of the door and window body.

[0021] Furthermore, the pulley frame includes a pulley frame body and a cover plate covering the pulley frame body. The cover plate has a guide hole, and the pulley frame body has an arc-shaped groove that connects to the guide hole and is adapted to its shape. The guide hole and the arc-shaped groove are interconnected to form the curved groove.

[0022] Furthermore, the sliding seat is provided with a groove for the slider to slide.

[0023] In addition, this utility model also provides a door and window system, including the above-mentioned multi-row push-pull side-pressure pulley assembly, door and window body, and door frame, wherein:

[0024] The side-shifting pulley assembly is installed at the bottom of the door / window body;

[0025] The bottom of the door frame is equipped with a lower track, and the guide pulley group slides on the lower track.

[0026] In summary, the multi-row push-pull side-pressure pulley assembly and door / window system provided by this utility model have the following beneficial effects:

[0027] (1) The guide pulley group is arranged in pairs on the left and right sides of the lateral pulley assembly, and the guide pulley group includes at least two first guide pulleys arranged in parallel along the front and rear direction. Thus, by setting the guide pulley group into a multi-row structure, the force-bearing surface of the guide pulley group is multiplied, thereby greatly increasing the load-bearing capacity of the guide pulley group and ensuring the stability of the door and window body during sliding and lateral movement.

[0028] (2) By setting up an elastic component, when an imbalance of forces occurs, that is, when the load on the multi-row push-pull side pressure pulley assembly of the door and window body is greater than the initial tension of the elastic component, the elastic component can deform. The pressure of the elastic component on the guide pulley group will never exceed its maximum bearing capacity, so it will not cause damage. At the same time, the guide pulley group can move up and down relative to the pulley plate to rebalance the pressure on each pulley, thereby reducing the pressure on a single pulley and preventing the pulley from getting stuck or damaged, thus ensuring the normal use of the door and window system.

[0035] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] Example 1

[0039] See Figure 1-4This utility model provides a multi-row push-pull side-pressure pulley assembly, including a side-moving pulley assembly 1, pulley plates 2, and guide pulley group 3. The side-moving pulley assembly 1 is installed at the bottom of the door / window body to realize the side movement of the door / window body. The pulley plates 2 are arranged in pairs at intervals on the front and rear sides of the side-moving pulley assembly 1. The guide pulley group 3 is clamped and movably connected between the two pulley plates 2 and is arranged in pairs at intervals on the left and right sides of the side-moving pulley assembly 1. The guide pulley group 3 includes two first guide pulleys 31 arranged side by side in the front-rear direction. The first guide pulleys 31 are used to slide on the lower track of the door frame.

[0040] Therefore, by setting the guide pulley group 3 into a multi-row structure, the force-bearing surface of the guide pulley group 3 is multiplied, thereby greatly increasing the load-bearing capacity of the guide pulley group 3 and ensuring the stability of the door and window body during sliding and lateral movement.

[0041] Of course, it should be noted that in other embodiments, the guide pulley group 3 may also be three or more first guide pulleys 31 arranged side by side in the front-back direction. The specific number can be adjusted according to the actual situation, and the number of first guide pulleys 31 is not limited here.

[0042] In addition, the multi-row push-pull side-pressure pulley assembly also includes elastic components 4, the number of which corresponds to the number of guide pulley groups 3. Specifically, the elastic component 4 includes a mounting base 41 clamped and fixedly connected between the two pulley plates 2, a shock absorber 42 connected to the guide pulley group 3 and rotatably sleeved on the outer side of the two pulley plates 2, and elastic elements 43 respectively connected to the mounting base 41 and the shock absorber 42. When the pressure applied by the door / window body to the guide pulley group 3 is greater than the initial tension of the elastic element 43, the elastic element 43 can deform, and several first guide pulleys 31 in the guide pulley group 3 can move up and down relative to the pulley plates 2 to achieve balance. Preferably, the elastic element 43 is a return spring.

[0043] Therefore, by setting the elastic component 4, when an imbalance of forces occurs, that is, when the load on the multi-row push-pull side-pressure pulley assembly of the door and window body is greater than the initial tension of the elastic component 43, the elastic component 43 can deform. The pressure of the elastic component 43 on the guide pulley assembly 3 will never exceed its maximum bearing capacity, so it will not cause damage. At the same time, the guide pulley assembly 3 can move up and down relative to the pulley plate 2 to rebalance the pressure on each pulley, thereby reducing the pressure on a single pulley and preventing the pulley from jamming or being damaged, thus ensuring the normal use of the door and window system.

[0044] See also Figure 1-2It also includes a fixing pin 5 that passes through the guide pulley assembly 3. The pulley plate 2 has a positioning hole 21. The two ends of the fixing pin 5 pass through the two positioning holes 21 respectively to be movably connected to the pulley plate 2. Preferably, the positioning hole 21 is a vertically arranged and elongated waist-shaped hole. The fixing pin 5 can move up and down along the guide of the positioning hole 21 to realize the up and down movement of the first guide pulley 31.

[0045] In this embodiment, the shock absorber 42 has a U-shaped structure and mounting holes 421 are provided on both its front and rear sides. The mounting holes 421 of the shock absorber 42 are connected to the ends of the fixing pins 5 to achieve connection with the guide pulley group 3.

[0046] Furthermore, the shock absorber 42 is provided with locking holes 422 on both the front and rear sides, and the pulley plate 2 is provided with locking blocks 22. The shock absorber 42 is fitted onto the locking blocks 22 through the locking holes 422 to achieve a rotatable connection.

[0047] Of course, in other implementations, the positions of the card slot 422 and the card block 22 can be interchanged to achieve the same technical effect, and there are no restrictions here.

[0048] See Figure 3-4 The lateral pulley assembly 1 includes a sliding seat 11 installed at the bottom of the door / window body, a pulley frame 14 slidably engaged with the sliding seat 11, and a slider 12 slidably passing through the sliding seat 11 and drivingly engaged with the pulley frame 14. The slider 12 is used for driving connection with the transmission bar. The pulley frame 14 is provided with a second guide pulley 15, the central axis of which is perpendicular to the central axis of the first guide pulley 31 (in this embodiment, the central axis of the second guide pulley 15 is arranged in the vertical direction, and the central axis of the first guide pulley 31 is arranged in the front-back direction). The pulley plates 2 are arranged in pairs at intervals on the front and back sides of the pulley frame 14, and the guide pulley groups 3 are arranged in pairs at intervals on the left and right sides of the pulley frame 14.

[0049] Therefore, when the transmission bar is driven to slide so that the slider 12 slides on the sliding seat 11, it can drive the sliding seat 11 to move laterally relative to the pulley frame 14 through its transmission cooperation with the pulley frame 14, thereby driving the door and window body to move laterally and press the second guide pulley 15.

[0050] In this embodiment, the sliding seat 11 is provided with a sliding groove 111 for the slider 12 to slide and a sliding cavity 112 that slides and engages with the pulley frame 14.

[0051] Furthermore, it also includes a drive shaft 13 passing through the slider 12. The pulley frame 14 has a curved groove. One end of the drive shaft 13 is connected to the transmission bar, and the other end of the drive shaft 13 extends into the curved groove and engages with it in a sliding fit. Thus, when the transmission bar is driven to slide and the slider 12 is driven to slide in the groove 111 on the sliding seat 11 through the drive shaft 13, the sliding seat 11 can be moved laterally relative to the pulley frame 14 through the engagement and sliding fit between the drive shaft 13 and the curved groove, thereby realizing the lateral movement of the door and window body.

[0052] Specifically, the pulley frame 14 includes a pulley frame body 141 and a cover plate 142 covering the pulley frame body 141. The cover plate 142 has a guide hole 1421. The pulley frame body 141 has an arc-shaped groove 1411 that connects to the guide hole 1421 and is adapted to its shape. The guide hole 1421 and the arc-shaped groove 1411 are interconnected to form a curved groove.

[0053] Furthermore, it also includes a limiting clamp 16 detachably mounted on the sliding seat 11. The limiting clamp 16 is used to abut against the pulley frame 14 to prevent the sliding seat 11 from shifting laterally relative to the pulley frame 14. Specifically, the limiting clamp 16 is provided with symmetrically arranged elastic buckles, and the sliding seat 11 is provided with a limiting hole 113. The limiting clamp 16 is detachably engaged in the limiting hole 113 by means of the elastic buckles.

[0054] Therefore, when the side-moving pulley assembly 1 needs to be assembled onto the door and window body, the limiting clamp 16 needs to be installed on the sliding seat 11 to prevent the sliding seat 11 from moving sideways; after the assembly is completed, the limiting clamp 16 can be removed to ensure the normal operation of the side-moving motion.

[0055] Example 2

[0056] In addition, this utility model also provides a door and window system, including the above-mentioned multi-row push-pull side-pressure pulley assembly, door and window body and door frame. The side-sliding pulley assembly 1 is installed at the bottom of the door and window body; a lower track is installed at the bottom of the door frame, and the guide pulley group 3 slides on the lower track.

[0057] In summary, the multi-row push-pull side-pressure pulley assembly and door / window system provided by this utility model have the following beneficial effects:

[0058] (i) The guide pulley group 3 is arranged in pairs at intervals on the left and right sides of the lateral pulley assembly 1, and the guide pulley group 3 includes at least two first guide pulleys 31 arranged in parallel along the front and rear direction. Thus, by setting the guide pulley group 3 into a multi-row structure, the force-bearing surface of the guide pulley group 3 is multiplied, thereby greatly increasing the load-bearing capacity of the guide pulley group 3 and ensuring the stability of the door and window body during sliding and lateral movement.

[0059] (ii) By setting the elastic component 4, when an imbalance of force occurs, that is, when the load on the multi-row push-pull side-pressure pulley assembly of the door and window body is greater than the initial tension of the elastic component 43, the elastic component 43 can deform. The pressure of the elastic component 43 on the guide pulley group 3 will never exceed its maximum bearing capacity, so it will not cause damage. At the same time, the guide pulley group 3 can move up and down relative to the pulley plate 2 to rebalance the pressure on each pulley, thereby reducing the pressure on a single pulley and preventing the pulley from jamming or being damaged, thus ensuring the normal use of the push-pull side-pressure door and window system.

[0060] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0061] It should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
