Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door and window accessories, in particular to a guide anti-sway wheel. Background Art
[0002] An airtight door and window accessory includes a base, a slider slidably arranged on the base, and a pull rod slidably installed on a fixed frame, and a 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, and the guide column is slidably arranged in the guide groove, and the slider is moved horizontally by the relative sliding between the pull rod and the base in the longitudinal direction under the guidance of the guide column and the guide groove. When the door and window sash is closed, the door and window sash is moved closer to the door and window frame through lateral movement, which plays a role in reducing the gap and increasing the sealing effect.
[0003] The wheel set includes rolling wheels and auxiliary wheels. In order to install the auxiliary wheels in the guide slide groove, there is a gap between the auxiliary wheels and the side walls of the guide slide groove, and the door and window sashes are prone to shaking due to force. If the door and window sashes are in a closed state at this time, the door and window sashes are closer to the door and window frames, and the door and window sashes are more likely to hit the doors and windows when shaking, causing the doors and windows to be easily damaged. Utility Model Content
[0004] The utility model aims to provide a guide anti-balance wheel 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 technical problems is as follows: a guide anti-sway wheel includes: a base plate, which is provided with a slot; a pull rod, which is arranged on one side of the base plate, and the pull rod is equipped with a guide column; 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 guide groove, and the guide column passes through the slot and slides in the guide groove, and the guide groove has a portion that extends obliquely along the width direction of the slot, so that when the pull rod slides longitudinally relative to the base plate, the sliding block slides transversely relative to the base plate, and at least two auxiliary pulleys are installed on the side of the sliding block away from the base plate, and the line connecting the axes of the two auxiliary pulleys is not parallel to the length direction of the slot.
[0006] This technical solution has at least the following beneficial effects: when the pull rod slides longitudinally along the length direction of the slot relative to the bottom plate, the guide column slides in the slot and the guide groove, and under the guiding action of the guide groove, the sliding block is driven to move horizontally relative to the bottom plate, so that when the door and window are closed, the door and window sash can be closer to the door and window frame, reducing the interval, improving the sealing effect, and reducing the shaking, ensuring the stability of the door and window sash. When installing two auxiliary pulleys with mutually offset axes in the corresponding installation grooves, the anti-sway wheel can be deflected as a whole to a position where the axis connection direction of the two auxiliary pulleys is parallel to the length direction of the installation groove. After the two auxiliary pulleys are embedded in the installation groove, the position of the anti-sway wheel as a whole is reversely deflected so that the length direction of the slot is parallel to the length direction of the installation groove. At this time, the axis connection line of the two auxiliary pulleys is not parallel to the length direction of the installation groove, so that the two auxiliary pulleys are in a state where one side of one of them conflicts with the side wall of the guide slide groove and the other side has a gap with the side wall of the guide slide groove, and the two auxiliary pulleys conflict with the two side walls of the guide slide groove at different side positions. Both sides of the anti-swing wheel are in contact with the side walls of the installation groove without any gap, so as to ensure the stability of the anti-swing wheel when sliding along the length direction of the installation groove, thereby driving the stable movement of the door and window sashes, and further reducing the shaking of the door and window sashes. When the doors and windows are closed, even if the door and window sashes are closer to the door and window frames, they are not easy to hit the door and window frames due to shaking, which better ensures the quality of the doors and windows after long-term use. At the same time, it can always ensure that any auxiliary pulley only contacts one side of the guide groove, so that the auxiliary pulley slides more smoothly, avoiding the phenomenon that a single auxiliary pulley contacts both sides of the guide groove at the same time when moving, thereby causing friction between the auxiliary pulley and the side of the guide groove.
[0007] As a further improvement of the above technical solution, the bottom plate is installed with a positioning 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. When the pull rod slides relative to the bottom plate, in addition to being restricted by the notch of the fixed frame, it is also restricted by the positioning column on the bottom plate, so that the self-guiding between the pull rod and the bottom plate can be achieved, and the relative sliding direction between the pull rod and the bottom plate can be made more accurate, thereby reducing the loss of the lateral translation amount of the sliding block due to the inaccurate restriction of the fixed frame profile on the pull rod, so that the airtight effect that can be achieved by the door and window is more stable.
[0008] As a further improvement of the above technical solution, the feature is that: two positioning posts are provided, the two positioning posts are respectively located near the two ends of the slot, and the pull rod is provided with two positioning grooves corresponding to the positioning posts. 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, it is characterized in that: the outer circumference of the guide column and the positioning column are both rotatably provided with guide sleeves. The outer circumference 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, so that the sliding between the pull rod and the bottom plate and the sliding between the sliding block and the bottom plate are smoother and more stable.
[0010] As a further improvement of the above technical solution, it is characterized in that: a side guard is provided on the bottom plate close to the sliding block, and 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.
[0011] As a further improvement of the above technical solution, the feature is that: a receiving groove is provided on the bottom plate near the sliding block, and the sliding block is slidably arranged in the receiving groove. The sliding direction of the sliding block is limited by the side wall of the receiving groove, so that the relative sliding stability between the sliding block and the bottom plate can be ensured.
[0012] As a further improvement of the above technical solution, a plurality of marbles are installed on both sides of the sliding block, and the side portions of the marbles and the bottom portions close to the bottom plate protrude from the surface of the sliding block and respectively contact the side walls and bottom walls of the receiving groove. The sliding block contacts the bottom plate through the marbles, 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. In addition, the friction and active gap between the sliding block and the bottom plate are reduced 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.
[0013] 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 bottom wall of the receiving groove for the slider to slide in a limited position. The structure in which the slider and the slide groove slide in cooperation with each other further limits the lateral sliding direction of the sliding block, and further ensures the lateral sliding stability of the sliding block.
[0014] 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.
[0015] 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0029] Reference Figure 1-6A guide anti-sway wheel comprises 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. An auxiliary 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 auxiliary pulley 31 move transversely synchronously, the door and window sash can be driven to move transversely as a whole, 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.
[0030] There are two auxiliary pulleys 31, and a preset angle is set between the straight line connecting the axes of the two auxiliary pulleys 31 and the length direction line of the slot hole 11, and the angle is less than or equal to 90 degrees. In the case of a small installation space, the angle is less than 2 degrees, so that the axes of the two auxiliary pulleys 31 are offset from each other. When installing the auxiliary pulley in the corresponding installation groove, the whole can be deflected to a position where the direction of the axis line of the two auxiliary pulleys is parallel to the length direction of the installation groove, which can facilitate the installation of the two auxiliary pulleys in the installation groove, and then the position of the whole is reversely deflected so that the length direction of the slot hole is parallel to the length direction of the installation groove. At this time, the two auxiliary pulleys 31 respectively contact the two side walls of the installation groove, so that there is no gap between the overall structure and the side walls of the installation groove, which better guarantees the stability of the door and window sash when moving and reduces the shaking of the door and window sash.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] In order to further improve the sliding stability of the sliding block 30 on the bottom plate 10, a receiving groove 35 with two ends passing through is provided 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 35. A plurality of marble grooves are provided on both side edges of the sliding block 30 close to the side wall of the receiving groove 35, 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 is pressed against the bottom wall and side wall of the receiving groove 35 respectively, and the bottom wall and side wall of the receiving groove 35 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.
[0036] 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.
[0037] Reference Figure 7In other embodiments, a rolling pulley 36 is installed on the side of the sliding block 30 away from the bottom plate 10. In this case, it is inconvenient to install a pressure plate 50 on both sides of the bottom plate 10 to restrict the sliding block 30. Instead of setting the pressure plate 50 structure, a slider 33 is set on the side of the sliding block 30 close to the bottom plate 10, and a slide groove 34 is correspondingly opened on the side of the bottom plate 10 close to the sliding block 30. 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-shaped, T-shaped or other structure, and the inner shape of the slide groove 34 is adapted to the shape of the slider 33. 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.
[0038] 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.
