Description

Technical Field

[0001] This utility model relates to the field of door and window hardware technology, and in particular to a side-pressure translation pulley. Background Technology

[0002] With the development of interior partition design, side-pressure sliding doors and windows have gradually become the mainstream choice for interior partitions due to their large opening area and side-pressure sealing design. The sliding dynamic stability of these doors and windows is highly dependent on the structural design of the matching hardware, especially the sliding pulley assembly that bears the load and guides the movement.

[0003] Traditional side-pressure sliding pulleys typically use fixed rollers and rigid guide structures. The contact surfaces between the rollers and the guide rails are prone to wear due to frictional resistance during long-term use, which can cause jamming during the sliding of doors and windows.

[0004] However, the problem of uneven movement of existing translation pulley assemblies often creates a vicious cycle with guide rail deformation. When the guide rail is locally deformed due to installation errors or external forces, the rigidly connected rollers cannot adaptively compensate for the guide rail deformation. Instead, they exacerbate the abnormal wear of the contact surface, causing sliding jamming. This not only accelerates the wear of hardware but also significantly reduces the overall stability of the door and window system.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a side-pressure translation pulley to solve the technical problems of motion jamming and poor guide rail adaptability of the side-pressure translation pulley in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A side-pressure translation pulley, comprising:

[0009] Mounting bracket for mounting on a movable sector frame;

[0010] A sliding seat, which is slidably disposed within a fixed seat;

[0011] The driving component, located between the sector frame and the fixed base, is used to drive the sliding base to move relative to the fixed base;

[0012] The mounting base is rotatably connected to the sliding base. Several rollers are rotatably connected inside the mounting base, and there is a gap between the top of the mounting base and the inner top of the sliding base.

[0013] Furthermore, a guide wheel is rotatably connected inside the mounting base, and the axis of the guide wheel is perpendicular to the axis of the roller; and on the vertical projection plane, the width of the guide wheel is greater than the width of the roller.

[0014] Furthermore, the guide wheel is located below the rotation center of the mounting base and the sliding base.

[0015] Furthermore, the sliding seat has a clearance hole located above the roller.

[0016] Furthermore, the mounting base includes two parallel side plates and a connecting plate connecting the bottom of the two side plates, a number of rollers located between the two side plates and rotatably connected to the side plates, and guide wheels rotatably connected to the connecting plate.

[0017] Furthermore, the driving component includes a transmission rod and a short transmission shaft fixed at the bottom of the transmission rod. The transmission rod is located between the sector frame and the fixed seat. A translation guide groove is opened on the sliding seat, and the short transmission shaft is slidably connected to the translation guide groove.

[0018] Furthermore, guide sleeves are symmetrically arranged on the sliding seat, and two guide rods are provided on the fixed seat, with each guide rod correspondingly inserted into a guide sleeve.

[0019] Furthermore, the guide rod is screwed with a locking screw after passing through the fixed seat; one end of the guide rod is provided with a first nut that abuts against one side of the fixed seat, and one end of the locking screw is provided with a second nut that abuts against the other side of the fixed seat.

Detailed Implementation

[0029] This utility model provides a side-pressure translational pulley. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," and "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0031] This utility model utilizes a side-pressure sliding hardware system in its side-pressure sliding doors and windows to achieve a sliding connection between the sash frame and the guide rail. This system includes a handle, a linkage assembly, and a side-pressure sliding pulley. During operation, the side-pressure sliding pulley moves with the sash frame, and the handle controls the linkage, which in turn drives the pulley to change its motion. When the sash frame is in a side-pushing position, the pulley moves along the extension direction of the guide rail, opening and closing the door / window. In the closed state, controlling the handle causes the linkage assembly to drive the pulley to move perpendicular to the guide rail, ensuring the sash frame is tightly pressed against the guide rail and guaranteeing a seal between them.

[0032] It should be noted that the handle, linkage assembly, guide rail, and fan frame in this utility model are not shown in the accompanying drawings.

[0033] Please see Figures 1 to 5 As shown, this utility model provides a side-pressure translational pulley, including: a fixed base 1, a sliding base 2, a driving component 3, and a mounting base 4; the fixed base 1 is used to be mounted on a movable fan frame; the sliding base 2 is slidably disposed within the fixed base 1; the driving component 3 is disposed between the fan frame and the fixed base 1, and is used to drive the sliding base 2 to move relative to the fixed base 1; the mounting base 4 is rotatably connected to the sliding base 2, and a plurality of rollers 5 are rotatably connected within the mounting base 4, and there is a gap between the top of the mounting base 4 and the inner top of the sliding base 2.

[0034] Specifically, the fixed base 1 is installed at the bottom of the fan frame with screws. During the push-pull process, the roller 5 slides along the length of the guide rail 10. Since the mounting base 4 for mounting the roller 5 is rotatably connected to the sliding base 2, that is, the mounting base 4 can swing around the rotation center, when sliding on the guide rail 10 with bending deformation, the mounting base 4 can swing adaptively according to the shape of the guide rail 10, so that the roller 5 located on the mounting base 4 always fits the surface of the guide rail 10. Through the above settings, the jamming problem of traditional rigid structures on the bending deformation guide rail 10 is effectively overcome, ensuring that the fan frame slides smoothly and steadily.

[0035] When the doors and windows are closed and require lateral pressure sealing, the drive unit 3 pushes the sliding seat 2 to move laterally relative to the fixed seat 1. Since the roller 5 is constrained by the guide rail 10, the fixed seat 1 is forced to move laterally to the guide rail 10, causing the sash frame to press laterally against the guide rail 10 to ensure the sealing between the sash frame and the guide rail 10.

[0036] In a preferred embodiment, see [reference] Figure 2 , 3 5. A guide wheel 6 is rotatably connected inside the mounting base 4. The axis of the guide wheel 6 is perpendicular to the axis of the roller 5. Furthermore, on the vertical projection plane, the width of the guide wheel 6 is greater than the width of the roller 5. The guide wheel 6 rolls along the side wall of the guide rail 10. By setting the guide wheel 6, the movement of the roller 5 is guided during the movement of the fan frame, preventing the roller 5 from deviating from the track. Simultaneously, when the roller 5 is subjected to lateral force that may press against the guide rail 10, the guide wheel 6 preferentially contacts the edge of the guide rail 10 and bears the lateral pressure, avoiding direct compression of the guide rail 10 by the side of the roller 5, thus ensuring the structural integrity and sliding stability of the roller 5.

[0037] Furthermore, the guide wheel 6 is located below the rotation center of the mounting base 4 and the sliding base 2. This arrangement ensures that the guide wheel 6 always rolls along the side wall of the guide rail 10 during the movement of the fan frame, and the movement trajectory is on the same plane, unaffected by the swing of the mounting base 4.

[0038] In the above description, there is a gap between the top of the mounting base 4 and the inner top of the sliding base 2. Specifically, a first round rod 24 is riveted to the sliding base 2, and the mounting base 4 is rotatably connected to the first round rod 24, that is, the mounting base 4 has a swinging degree of freedom around the axis of the first round rod 24. The aforementioned gap provides sufficient swinging space for the mounting base 4 to rotate around the axis of the first round rod 24, so that the mounting base 4 can make adaptive swinging.

[0039] In a preferred embodiment, see [reference] Figure 3 , 4 The sliding seat 2 has a clearance hole 21 located above the roller 5. When the roller 5 swings upward with the mounting base 4 around the axis of the first round rod 24, the clearance hole 21 prevents positional interference between the sliding seat 2 and the roller 5. In addition, the above arrangement can effectively reduce the overall height of the lateral pressure translation pulley.

[0040] Furthermore, the mounting base 4 includes two parallel side plates 41 and a connecting plate 42 connecting the bottoms of the two side plates 41, making the cross-section of the mounting base 4 U-shaped. The mounting base 4 is manufactured using an integral stamping process. Several rollers 5 are located between the two side plates 41 and are rotatably connected to the side plates 41, and guide wheels 6 are rotatably connected to the connecting plate 42. In this embodiment, there are four rollers 5. Second round rods 51 are riveted to both ends of the side plates 41, two rollers 5 are arranged side by side and rotatably connected to a second round rod 51, and a third round rod 61 is vertically riveted to the connecting plate 42. The third round rod 61 is rotatably connected to the guide wheel 6. Through the above arrangement, both the rollers 5 and the guide wheels 6 are fixed on the mounting base 4, ensuring that the rollers 5 and the guide wheels 6 slide as a whole and permanently maintain their relative positional relationship. When the guide rail 10 deforms, the mounting base 4 swings adaptively around the axis of the first round rod 24 to maintain the movement of each roller 5 along the guide rail 10. At the same time, the offset amplitude is constrained by the guide wheel 6, thus ensuring the smoothness of the door movement.

[0041] In a preferred embodiment, see [reference] Figure 1 , 2 The driving component 3 includes a transmission rod 31 and a short transmission shaft 32 fixed to the bottom of the transmission rod 31. The transmission rod 31 is located between the fan frame and the fixed seat 1. The transmission rod 31 is driven to translate by the linkage assembly in the side-pressure translation hardware system, so that the transmission rod 31 translates a distance relative to the fan frame. The sliding seat 2 has a translation guide groove 25. The short transmission shaft 32 is slidably connected to the translation guide groove 25. On the horizontal plane, the translation guide groove 25 is inclined. The short transmission shaft 32 translates a distance with the transmission rod 31. At the same time, the short transmission shaft 32 moves along the translation guide groove 25. Since the roller 5 is constrained by the guide rail 10, the fixed seat 1 is forced to translate laterally toward the side wall of the guide rail 10, thereby realizing the lateral pressing of the fan frame against the guide rail 10.

[0042] As described above, because the cross-section of the mounting base 4 is U-shaped, meaning the top of the mounting base 4 is an open design, the short transmission shaft 32 extends through the translation guide groove 25 into the mounting base 4, and remains in a non-contact state with the mounting base 4 during movement. This further effectively reduces the overall height of the side-pressure translation pulley.

[0043] See Figure 3 The gap between the mounting base 4 and the sliding base 2 provides sufficient swing space for the mounting base 4 to swing; the clearance hole 21 on the top of the sliding base 2 eliminates the motion interference when the roller 5 swings around the first round rod 24; and combined with the open design of the mounting base 4, the overall height of the side pressure translation pulley in the vertical direction is minimized while ensuring the adaptive swing function of the mounting base 4, thus achieving a compact overall height design.

[0044] In a preferred embodiment, see [reference] Figure 5 The sliding seat 2 is symmetrically provided with guide sleeves 22, and the fixed seat 1 is provided with two guide rods 7, each of which is inserted into a guide sleeve 22. Specifically, the guide sleeves 22 are fixed to the sliding seat 2 by riveting or welding. The guide sleeves 22 and the guide rods 7 cooperate to form a precise sliding pair, which guides the movement of the fixed seat 1 along the axis of the guide rods 7. Furthermore, the large contact area between the guide sleeves 22 and the guide rods 7 significantly improves the stability of the axial translation of the fixed seat 1.

[0045] Furthermore, the guide rod 7 passes through the fixed seat 1 and is screwed with a locking screw 8. One end of the guide rod 7 is provided with a first nut 71 that abuts against one side of the fixed seat 1, and one end of the locking screw 8 is provided with a second nut 81 that abuts against the other side of the fixed seat 1. The first nut 71 and the second nut 81 respectively form an axial positioning of the guide rod 7 with the two sides of the fixed seat 1. Compared with the riveting process in the prior art, the screwed connection structure of the guide rod 7 and the locking screw 8 eliminates the coaxiality deviation and circular runout error caused by the expansion or bending of the rivet during riveting, ensuring the stability of the axial translation of the fixed seat 1. At the same time, the detachable screwed connection design, while ensuring the rigid locking of the guide rod 7 and the fixed seat 1, facilitates the modular replacement of related components such as the guide sleeve 22 or the sliding seat 2, significantly improving maintenance efficiency and the maintainability of the side-pressure translation pulley.

[0046] In a preferred embodiment, see [reference] Figure 2 , 5The fixed seat 1 has several sets of rolling elements 9 between its top and the top of the sliding seat 2. The top of the sliding seat 2 has several grooves 23, the length of which is parallel to the sliding direction of the sliding seat 2. Each set of rolling elements 9 is accommodated in one groove 23. In this embodiment, there are two grooves 23, symmetrically located at both ends of the sliding seat 2. The fixed seat 1 bears the weight of the door and window. The rolling elements 9 are accommodated in the grooves 23. Under the sliding fit constraint of the guide rod 7 and the guide sleeve 22, the sliding friction between the fixed seat 1 and the sliding seat 2 is transformed into rolling friction, greatly reducing the friction between the fixed seat 1 and the sliding seat 2, thereby further improving the smoothness of the door and window when sliding.

[0047] In this embodiment, the rolling element 9 is a plurality of steel balls. The steel balls are housed in a groove 23, and their installation positions are locked by the sliding engagement of the guide rod 7 and the guide sleeve 22 to prevent them from dislodging from the groove 23 during movement, thus ensuring the long-term reliability of the steel balls. Furthermore, the guide rod 7 is detachable; removing the guide rod 7 directly exposes the steel balls within the groove 23, facilitating maintenance and replacement of the steel balls.
