Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to an anti-sway wheel assembly. Background Art

[0002] An airtight window is a window that moves horizontally when closed, so that the window sash is closer to the window frame, which reduces the gap and increases the sealing effect. Its main accessories for realizing the function include a base, a slider that slides horizontally on the base, and a pull rod that slides on the fixed frame, and the wheel set is installed on the slider; a Z-shaped or inclined guide groove is opened at the bottom of the slider, and a guide column is installed on the pull rod, which is slidably set in the guide groove. Through the relative sliding between the pull rod and the base in the longitudinal direction, the slider can realize horizontal movement under the guidance of the guide column and the guide groove.

[0003] However, due to the difference in the width of the slots for the pull rod to slide in different fixed frames, there is a gap between the two sides of the pull rod and the inner wall of the slot of the fixed frame, which causes the pull rod to be offset in the lateral direction, thereby affecting the displacement stroke of the slider in the lateral direction. Utility Model Content

[0004] The utility model aims to provide an anti-sway wheel assembly to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: an anti-sway wheel assembly, comprising: a base plate, which is provided with a slot hole, and a positioning column is installed on the base plate; a pull rod, which is arranged on one side of the base plate, and the pull rod is provided with a guide column, and the pull rod is provided with a positioning groove for the positioning column to slide, and the length direction of the positioning groove is the same as the length direction of the slot hole; a sliding block, which is slidably arranged on the side of the base plate away from the pull rod, and the sliding block is provided with a pulley, and the sliding block is provided with a guide groove, the guide column passes through the slot hole and slides in the guide groove, and the guide groove has a portion extending obliquely along the width direction of the slot hole, so that when the pull rod slides longitudinally relative to the base plate, the sliding block slides laterally relative to the base plate.

[0006] This technical solution has at least the following beneficial effects: when the pull rod and the base plate slide relative to each other, in addition to being restricted by the grooves of the fixed frame, they are also restricted by the positioning columns on the base plate, thereby achieving self-guidance between the pull rod and the base plate, and making the relative sliding direction between the pull rod and the base plate more precise, thereby reducing the loss of lateral translation of the sliding block due to the inaccurate restriction of the fixed frame profile on the pull rod, and making the airtight effect that can be achieved by doors and windows more stable.

[0007] As a further improvement of the above technical solution, the outer circumferences of the guide column and the positioning column are both rotatably provided with guide sleeves. The relative rotation between the guide sleeve and the positioning column and between the guide sleeve and the guide column can reduce the friction between the corresponding positioning groove and the side wall of the guide groove, making the sliding between the pull rod and the bottom plate and the sliding between the sliding block and the bottom plate smoother and more stable.

[0008] As a further improvement of the above technical solution, two positioning posts are provided, and the two positioning posts are respectively located near the two ends of the slot, and the pull rod is provided with two corresponding positioning grooves. The relative sliding direction between the pull rod and the bottom plate is positioned and restricted by the action points on both sides, so as to better ensure the accuracy of the relative sliding direction between the pull rod and the bottom plate.

[0009] As a further improvement of the above technical solution, a side guard is provided on the bottom plate near the sliding block. When the guide post slides to the end of the guide groove, the sliding block is clamped between the side guard and the guide post. In order to ensure that the guide post slides smoothly in the guide groove to drive the sliding block to move, there is often a gap between the guide post and the side wall of the guide groove. When the guide post slides to the end of the guide groove, the sliding block will have a small amount of lateral movement relative to the bottom plate, making the doors and windows easy to shake. After the side guard is provided, the sliding block can be clamped between the guide post and the side guard, thereby reducing the lateral movement of the sliding block, thereby reducing the shaking of the doors and windows, and better ensuring the stability of the use of the doors and windows.

[0010] As a further improvement of the above technical solution, a limit pin is installed on the bottom plate near the sliding block, and the sliding block is provided with a limit slot for the limit pin to slide in. The limit slot restricts the limit pin, so that the sliding block can slide within a certain range and will not fall out.

[0011] As a further improvement of the above technical solution, a slider is provided on the side of the sliding block close to the bottom plate, and a slide groove is provided on the side of the bottom plate close to the sliding block for the slider to slide in a limited position, and the slider can only slide out from the end of the slide groove. The inner wall of the slide groove restricts the slider from escaping from the slide groove opening, that is, the slider cannot be directly taken out from the middle of the slide groove, but can only slide out of the slide groove range from the end of the slide groove, so that the slider will not separate from the bottom plate when it is within the slide groove range. The structure in which the slider and the slide groove cooperate with each other and do not separate from each other limits the lateral sliding direction of the sliding block, thereby ensuring the lateral sliding stability of the sliding block.

[0012] As a further improvement of the above technical solution, pressure plates are installed on both sides of the bottom plate, and the sliding block is clamped between the pressure plates and the bottom plate. The sliding block is restricted by the pressure plates to prevent the sliding block from falling out.

[0013] As a further improvement of the above technical solution, the pressure plate is riveted to the bottom plate, which can better ensure the limiting effect of the pressure plate on the sliding block, effectively reduce the swing amplitude of the sliding block, and improve the sliding stability of the sliding block.

[0014] As a further improvement of the above technical solution, a marble is movably arranged on one side of the sliding block close to the bottom plate, and the part of the marble protruding from the surface of the sliding block contacts the surface of the bottom plate. The sliding block contacts the bottom plate through the marble, which can reduce the friction between the sliding block and the bottom plate during the sliding process, improve the smoothness between the sliding block and the bottom plate, and at the same time, effectively reduce the active gap between the sliding block and the bottom plate, better ensuring the stability of the sliding direction of the sliding block.

[0015] As a further improvement of the above technical solution, the bottom and side of the marble both protrude from the surface of the sliding block and respectively contact two perpendicular surfaces of the bottom plate, thereby reducing the friction and the movable gap between the sliding block and the bottom plate from two directions, further improving the smoothness between the sliding block and the bottom plate, and further ensuring the stability of the sliding direction of the sliding block.

[0028] Reference Figure 1-5, an anti-sway wheel assembly, comprising a base plate 10, a pull rod 20 and a sliding block 30. The sliding block 30 is slidably arranged on one side of the base plate 10, and a guide groove 22 is provided on the side of the sliding block 30 close to the base plate 10. A slot hole 11 corresponding to the guide groove 22 is provided in the middle of the base plate 10, and the position of the slot hole 11 corresponds to the position of the guide groove 22. The guide groove 22 has a portion extending obliquely along the width direction of the slot hole 11, so that the guide groove 22 has a lateral offset. The length direction of the slot hole 11 is perpendicular to the direction in which the sliding block slides relative to the base plate 10. The pull rod 20 is arranged on the side of the base plate 10 away from the sliding block 30, and a guide column 21 is installed in the middle of the pull rod 20, and the guide column 21 passes through the slot hole 11 and is slidably arranged in the guide groove 22. Among them, the guide groove 22 does not penetrate the sliding block 30. In other embodiments, the guide groove 22 can also penetrate the sliding block 30 without affecting the guiding effect of the guide column 21 on the sliding block 30. When the pull rod 20 slides along the length direction of the slot hole 11 relative to the bottom plate 10, i.e. longitudinally, the middle part of the guide column 21 slides in the slot hole 11, and the end of the guide column 21 away from the pull rod 20 slides in the guide groove 22, and under the guidance of the guide groove 22, the sliding block 30 is driven to move in a direction perpendicular to the length direction of the slot hole 11, i.e. transversely. A pulley 31 is installed on the side of the sliding block 30 away from the bottom plate 10. When the sliding block 30 and the pulley 31 move transversely synchronously, the door and window sash as a whole can be driven to move transversely together, thereby reducing the gap between the door and window sash and the fixed frame profile, thereby achieving the effect of improving the air tightness of the door and window.

[0029] Two positioning columns 12 are fixedly installed on one side of the bottom plate 10 near the pull rod 20. The two positioning columns 12 are fixed on the bottom plate 10 by riveting. The two positioning columns 12 are respectively located near the two ends of the slot 11. Positioning grooves 23 are provided on both sides of the pull rod 20. The length direction of the positioning grooves 23 is the same as the length direction of the slot 11. The two positioning columns 12 are respectively slidably arranged in the corresponding positioning grooves 23. Among them, the positioning grooves 23 penetrate the pull rod 20. In other embodiments, the positioning grooves 23 may not penetrate the pull rod 20, which does not affect the sliding of the positioning columns 12 in the positioning grooves 23. When the pull rod 20 and the base plate 10 slide relative to each other, in addition to being restricted by the groove of the fixed frame, the pull rod 20 is also restricted by the positioning column 12, so that the pull rod 20 and the base plate 10 can achieve self-guidance and mutual restriction, and the relative sliding direction between the pull rod 20 and the base plate 10 is more precise, thereby reducing the loss of lateral translation of the sliding block 30 due to the imprecise restriction of the fixed frame profile on the pull rod 20, so that the airtight effect that can be achieved by the doors and windows is more stable.

[0030] The outer circumferences of the guide post 21 and the positioning post 12 are both rotatably sleeved with a guide sleeve 13. After the guide sleeve 13 is disposed on the outer surface of the guide post 21, when the guide post 21 slides in the slot hole 11 and the guide groove 22, the guide sleeve 13 contacts the side walls of the slot hole 11 and the guide groove 22, thereby reducing the friction between the guide post 21 and the side walls of the slot hole 11 and between the guide post 21 and the side walls of the guide groove 22, thereby improving the sliding smoothness of the guide post 21; after the guide sleeve 13 is disposed on the outer surface of the positioning post 12, when the positioning post 12 slides in the positioning groove 23, the guide sleeve 13 contacts the side walls of the positioning groove 23, thereby reducing the friction between the positioning post 12 and the side walls of the positioning groove 23, thereby improving the sliding smoothness of the positioning post 12 in the positioning groove 23.

[0031] A retaining edge 32 is provided on the side of the bottom plate 10 close to the sliding block 30, and the retaining edge 32 can prevent the sliding block 30 from sliding on the bottom plate 10. When the guide column 21 slides to the end position of the guide groove 22, the side of the sliding block 30 close to the retaining edge 32 abuts against the retaining edge 32, so that the sliding block 30 is clamped by the retaining edge 32 and the guide column 21, thereby fixing the position of the sliding block 30, limiting the lateral movement of the sliding block 30, and thus reducing the shaking of the doors and windows, and better ensuring the stability of the use of the doors and windows. The retaining edge 32 can be set at both sides of the sliding block 30 to clamp and limit the end positions of the two lateral strokes of the sliding block 30; it can also be set at only one side of the sliding block 30 according to actual needs, and only clamp and limit the end position of one lateral stroke of the sliding block 30.

[0032] In order to limit the lateral sliding range of the sliding block 30, a limit pin 40 is arranged on the base plate 10, and a limit groove 41 is opened on the side of the sliding block close to the base plate 10. The length direction of the limit groove 41 is the same as the lateral sliding direction of the sliding block 30. One end of the limit pin 40 protrudes out of the base plate 10 and can be slidably arranged in the limit groove 41. The limit pin 40 and the base plate 10 are fixed by interference fit.

[0033] In order to further improve the sliding stability of the sliding block 30 on the bottom plate 10, a receiving groove with two ends passing through is opened on one side of the bottom plate 10 close to the sliding block 30, and the sliding block 30 slides horizontally in the receiving groove. A plurality of marble grooves are opened on both side edges of the sliding block 30 close to the side wall of the receiving groove, and the plurality of marble grooves on the same side are arranged in parallel along the edge of the sliding block 30, and each marble groove contains a marble 60, which can rotate freely in the marble groove but cannot move, and the sliding block 30 part protrudes from the bottom and one side of the marble 60 and presses against the bottom wall and side wall of the receiving groove respectively, and the bottom wall and side wall of the receiving groove are two perpendicular surfaces on the bottom plate 10. By replacing the surface restriction between the bottom plate 10 and the sliding block 30 with the rolling restriction of the marble 60, the friction between the sliding block 30 and the bottom plate 10 during the sliding process can be reduced, and the smoothness between the sliding block 30 and the bottom plate 10 can be improved. At the same time, the active gap between the sliding block 30 and the bottom plate 10 can be effectively reduced, and the stability of the sliding direction of the sliding block 30 can be better guaranteed. In addition, reducing the friction and active gap between the sliding block 30 and the bottom plate 10 in two directions can further improve the smoothness between the sliding block 30 and the bottom plate 10 and further ensure the stability of the sliding direction of the sliding block 30.

[0034] A pressure plate 50 is installed on both sides of the bottom plate 10. The pressure plate 50 and the bottom plate 10 are fixedly connected by riveting. One side of the pressure plate 50 presses against the side of the sliding block 30 away from the bottom plate 10, so that the sliding block 30 is clamped between the pressure plate 50 and the bottom plate 10, thereby limiting the position of the sliding block 30 and preventing the sliding block 30 from slipping away from the bottom plate 10. In addition, a guide column with a semicircular cross section is also provided on the side of the sliding block 30 close to the bottom plate 10. The length direction of the guide column is the same as the lateral sliding direction of the sliding block 30. A guide groove is correspondingly provided on the side of the bottom plate 10 close to the sliding block 30. The guide column is slidably arranged in the guide groove, so that the sliding direction of the sliding block 30 can be better positioned and limited, and the stability of the sliding block 30 is improved.

[0035] Reference Figure 6In other embodiments, if it is necessary to install a component composed of multiple rollers 31 on the side of the sliding block 30 away from the bottom plate 10, and it is inconvenient to install a pressure plate 50 on both sides of the bottom plate 10 to restrict the sliding block 30, it is possible to choose not to set the pressure plate 50 structure, but to set a slider 33 on the side of the sliding block 30 close to the bottom plate 10, and the bottom plate 10 is correspondingly provided with a slide groove 34 on the side close to the sliding block 30, and the slider 33 can only slide out from one end or both ends of the slide groove 34. Specifically, the cross section of the slider 33 is a dovetail type, T-shaped or other structure, the inner shape of the slide groove 34 is adapted to the shape of the slider 33, and the slider 33 cannot be disengaged from the middle opening position of the slide groove 34, so that the slider 33 can only slide out from one end or both ends of the slide groove 34, thereby limiting the position of the sliding block 30 and preventing the sliding block 30 from disengaging in the direction away from the bottom plate 10. Of course, if a pressure plate 50 structure is provided, the slider 33 and the slide groove 34 structure can also be provided for combined use, and the two structures do not conflict.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
