Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a corner anti-sway wheel for a sliding airtight window. Background Technology

[0002] In the structure of sliding airtight windows, an anti-sway wheel assembly is installed to achieve lateral pressure sealing. The principle is that the drive column on the pull rod slides on the inclined guide groove of the anti-sway wheel, allowing the door / window to move laterally relative to the anti-sway wheel, thereby achieving lateral pressure sealing and improving the airtightness of the door / window. However, the pull rod generally needs to be driven by a corner mechanism to slide via the handle or other operating components. After the transmission plate of the corner mechanism is connected to the pull rod, the transmission between the transmission plate and the pull rod is prone to instability due to a mismatch between the installation position of the corner mechanism and the installation position of the anti-sway wheel assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a corner anti-sway wheel for a push-pull airtight window, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a corner anti-sway wheel for a push-pull airtight window, comprising: a corner block with a slidably mounted transmission plate, the sliding directions of the two ends of the transmission plate being perpendicular to each other; a base plate connected to the corner block, the base plate having a guide groove; a slider slidably mounted on the base plate along the length direction perpendicular to the guide groove, the slider having an inclined side pressure groove on one side facing the base plate, and a roller mounted on the side of the slider away from the base plate; and a pull rod disposed on the side of the base plate away from the slider, the pull rod having a sliding sleeve mounted thereon, the sliding sleeve passing through the guide groove and extending into the side pressure groove.

[0005] This technical solution offers at least the following advantages: The connection between the corner block and the base plate ensures accurate and coordinated relative installation positions, thereby guaranteeing stable and reliable transmission between the transmission plate and the tie rod. Furthermore, the smaller distance between the rollers and the corner position allows for better spacing between the two sets of rollers, resulting in more stable sash frame sliding for the same sash width. Additionally, it expands the range of usable door and window sizes.

[0006] As a further improvement to the above technical solution, the base plate is riveted to the corner block. This creates a stable integral structure between the corner block and the base plate, further ensuring the transmission stability between the transmission plate and the tie rod. It also improves the installation efficiency of door and window hardware.

[0007] As a further improvement to the above technical solution, the base plate is equipped with a pressure plate, and both the pressure plate and the corner block are respectively provided with limit grooves. The two ends of the slider are slidably disposed in the limit grooves, and the side walls of the limit grooves serve as retaining edges to limit the sliding range of the slider. By using the corner block and the pressure plate to restrict the slider, the sliding installation of the slider can be facilitated.

[0008] As a further improvement to the above technical solution, one side of the slider abuts against the sidewall of the limiting groove, and the other side abuts against the base plate. Utilizing the gap between the pressure plate and the base plate, as well as the gap between the corner block and the base plate, provides sliding installation space for the slider, which can reduce the overall thickness of the corner block, pressure plate, base plate, and slider, thus facilitating a more compact overall structure design.

[0009] As a further improvement to the above technical solution, when the sliding sleeve slides to one or both ends of the side pressure groove, both the side wall of the limiting groove and the sliding sleeve clamp the slider. It can be understood that when the sliding sleeve slides to one end of the side pressure groove, i.e., when side pressure is applied, the side wall of the limiting groove and the sliding sleeve clamp the slider, keeping it relatively fixed, thereby maintaining and improving the problem of door / window swaying. When the sliding sleeve slides to the other end of the side pressure groove, i.e., when side pressure is released, the other side wall of the limiting groove and the sliding sleeve clamp the slider, keeping it relatively fixed, thereby improving the stability of the door / window during sliding and improving the swaying problem of the door / window in the non-side pressure state.

[0010] As a further improvement to the above technical solution, the base plate is provided with a limiting rivet, the limiting rivet is fitted with a limiting sleeve, and the pull rod is provided with a sliding groove into which the limiting sleeve slides. This restricts the sliding of the pull rod relative to the base plate, ensuring the sliding stability and accuracy of the pull rod.

[0011] As a further improvement to the above technical solution, the base plate and the pressure plate are riveted together by the limiting rivets. The limiting rivets can rivet the base plate and the pressure plate simultaneously with the installation of the limiting roller sleeve, thereby simplifying the installation process and improving installation efficiency.

[0012] As a further improvement to the above technical solution, two rollers are provided, and the rotation center lines of the two rollers are perpendicular to the slider. When the connecting line between the rotation center points of the two rollers is projected onto the base plate, the direction of the connecting line forms a positive angle with the length direction of the guide groove. The opposite sides of the two rollers respectively abut against the track, which can ensure the lateral stability of the sliding. Furthermore, a small gap is formed between the opposite sides of the two rollers and the sidewall of the track, allowing each roller to run smoothly.

[0013] As a further improvement to the above technical solution, a first connector is provided between the transmission plate and the pull rod. The top of the first connector is connected to the transmission plate, and the bottom is connected to the pull rod. The first connector enables the connection between the transmission plate and the pull rod on different planes, ensuring stable transmission between them and further coordinating the connection positions between the corner block and the base plate.

[0014] As a further improvement to the above technical solution, the corner block is provided with a clearance through hole for connecting the transmission plate and the pull rod. This facilitates the connection between the transmission plate and the pull rod. Attached Figure Description

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figure 1-10 The corner anti-sway wheel of the sliding airtight window includes a corner block 100, a base plate 200, a slider 300, and a pull rod 400.

[0034] The corner block 100 has two ends that are perpendicular to each other. An inner groove is provided inside the corner block 100, with the middle of the groove curved and the length directions of both ends perpendicular to each other. A transmission plate 110 is slidably disposed in the inner groove, allowing the two ends of the transmission plate 110 to slide perpendicularly to each other at the two ends of the corner block 100, thus achieving a change in the transmission direction between the two ends of the transmission plate 110. The transmission plate 110 is made of a soft, elastic material, such as a steel sheet. In this embodiment, the transmission plate 110 is composed of three steel sheets stacked together. In other embodiments, the transmission plate 110 may also consist of one steel sheet or be composed of two or more steel sheets stacked together.

[0035] One side of the base plate 200 is riveted to one end of the corner block 100. The base plate 200 has a groove 220 on this side, and one end of the corner block 100 has a protrusion 230. The width of the protrusion 230 is the same as the width of the groove 220, allowing the protrusion 230 to embed into the groove 220. This relatively restricts the position of the corner block 100 and the base plate 200, facilitating riveting and improving the tightness of the connection between them. A guide groove 210 is provided in the middle of the base plate 200. In other embodiments, the base plate and the corner block 100 can also be integrally formed, welded, or bolted together.

[0036] A pressure plate 500 is installed at the end of the base plate 200 away from the corner block 100. Both the pressure plate 500 and the corner block 100 are mounted on the same side of the base plate 200. Limiting grooves 510 of the same size are formed at the ends of the corner block 100 and the pressure plate 500 that are close to each other. The two ends of the slider 300 slide within the limiting grooves 510 of the corner block 100 and the pressure plate 500, respectively, and the sliding direction of the slider 300 relative to the base plate 200 is perpendicular to the length direction of the guide groove 210. The two side walls of the limiting groove 510 form retaining edges 511. The width of the limiting groove 510, i.e., the distance between the two retaining edges 511, is greater than the width of the slider 300, thereby allowing the slider 300 to slide within the preset range between the two retaining edges 511.

[0037] One side of the limiting groove 510 extends through the side near the base plate 200, placing one end of the slider 300 between the corner block 100 and the base plate 200, and the other end between the pressure plate 500 and the base plate 200. This makes the assembly of the corner block 100, pressure plate 500, slider 300, and base plate 200 relatively thin, which is beneficial for the overall compactness of the structure. In addition, the thickness at both ends of the slider 300 is less than the thickness in the middle, forming a stepped structure on both sides of the top of the slider 300. Each side of the stepped structure abuts against the pressure plate 500 or corner block 100 on the corresponding side, thereby increasing the sliding restriction area of ​​the slider 300 and improving the sliding stability of the slider 300.

[0038] A side pressure groove 310 is formed on the bottom of the slider 300, on the side facing the base plate 200. The side pressure groove 310 is inclined, meaning that the line connecting the two ends of the side pressure groove 310 forms a certain angle with the length direction of the guide groove 210. In this embodiment, the axis of the length direction of the side pressure groove 310 is arc-shaped. Two rollers 320 are installed on the top of the slider 300, on the side away from the base plate 200. The rotation center lines 321 of the two rollers 320 are both perpendicular to the slider 300. Furthermore, the rotation center points of the two rollers 320 are located on the same plane parallel to the base plate 200. The rotation center points of the two rollers 320 are connected to form a connecting line 322. When the connecting line 322 is projected onto the base plate 200, the direction of the connecting line 322 and the length direction 323 of the guide groove form an angle greater than zero, causing the two rollers 320 to deflect laterally. When the two rollers 320 slide in the track, the laterally opposite sides of the two rollers 320 respectively abut against the side of the track, which can ensure the lateral stability of the slide. In addition, a small gap is formed between the laterally opposite sides of the two rollers 320 and the side wall of the track, so that each roller can run smoothly.

[0039] The pull rod 400 is located on the bottom side of the base plate 200, i.e., the side away from the slider 300. A sliding rivet 420 passes through the middle of the pull rod 400, and a sliding sleeve 410 is rotatably mounted on the sliding rivet 420. The sliding sleeve 410 is located on the top side of the pull rod 400 and extends through the guide groove 210 into the side pressure groove 310. A first connector 700 is installed at the end of the transmission plate 110 near the base plate 200, and the first connector 700 is connected to the end of the pull rod 400 near the corner block 100. Specifically, the end of the transmission plate 110 is riveted to the top of the first connector 700 by two rivets, and the end of the pull rod 400 is inserted into the bottom of the first connector 700 by a cylindrical block. This shortens the stroke required for the connection between the pull rod 400 and the transmission plate 110. At the same time, it enables the connection between the transmission plate 110 and the pull rod 400 on different planes, ensuring the transmission stability of the transmission plate 110 and the pull rod 400, and further coordinating the connection positions between the corner block 100 and the base plate 200.

[0040] Limiting rivets 600 are installed at both ends of the guide groove 210 on the base plate 200. Limiting rivets 600 are rotatably mounted with limiting sleeves 610, which are located on the bottom side of the base plate 200, near the tie rod 400. Sliding grooves 620 are formed on both sides of the tie rod 400, and the two limiting sleeves 610 are respectively inserted into the two sliding grooves 620. Thus, the sliding direction of the tie rod 400 can be limited by the sliding of the limiting sleeves 610 in the sliding grooves 620, ensuring the accuracy of the sliding of the tie rod 400 relative to the base plate 200.

[0041] The limiting rivet 600, located on the same side as the pressure plate 500, rivets the base plate 200 to the pressure plate 500, thereby improving installation efficiency. Positioning posts 520 are provided on both sides of the pressure plate 500 near the base plate 200 and at the position of the limiting sleeve 610. Two positioning grooves 530 are provided on the base plate 200 for the two positioning posts 520 to be inserted into. This allows for pre-installation of the pressure plate 500 and the base plate 200 before the limiting rivet 600 is installed, as the positioning action of the two positioning posts 520 corresponding to the two positioning grooves 530 facilitates subsequent riveting and ensures a stable connection between the pressure plate 500 and the base plate 200.

[0042] Reference Figure 11-12The pull rod 400 is slidably mounted on the door and window frame. Specifically, the door and window frame has a guide groove with a notch at one end, allowing the pull rod 400 to slide into the guide groove, thus achieving a sliding connection between the pull rod 400 and the door and window frame. The pressure plate 500, corner block 100, and base plate 200 are fixedly connected to form a fixed structure. Countersunk holes are provided at all four corners of this fixed structure. By inserting screws into the countersunk holes, the fixed structure can be installed in the door and window frame 800, with the corner block 100 corresponding to the corner position of the door and window frame 800. An initial positioning block 900 is installed on the side of the corner block 100 away from the base plate 200 to facilitate the positioning and installation of the corner block 100. A second connector 710 is riveted to the end of the transmission plate 110 away from the pull rod 400. The second connector 710 can be used to connect the transmission rod of the door and window handle.

[0043] When operating the door and window handle, the pull rod 400 can be moved by the transmission rod and transmission plate 110. During the sliding process of the sliding sleeve 410 in the side pressure groove 310, under the inclined guidance of the side pressure groove 310, the slider 300 is driven to move in the sliding direction of the vertical pull rod 400, that is, to move laterally. This allows the base plate 200 and the door and window frame 800 to move laterally relative to the slider 300. Since the slider 300 is restricted to the track at the installation position by the roller 320, the door and window frame 800 moves laterally relative to the track to achieve side pressure, thereby improving the airtightness of the door and window.

[0044] In addition, a third connector 720 is riveted to the end of the pull rod 400 away from the transmission plate 110. The third connector 720 can be used to install a connecting rod, thereby facilitating the connection of two adjacent pull rods 400 on the same side.

[0045] When the sliding sleeve 410 is at one end of the side pressure groove 310, it can be understood that the door and window frame 800 is in the open state, that is, in the non-side pressure state. The side wall of the sliding sleeve 410 abuts against the slider 300, and the slider 300 also abuts against the side edge 511 on the same side of the limiting groove 510 of the pressure plate 500 and the corner block 100. Thus, the side wall of the limiting groove 510, that is, the two side edges 511 on the same side, and the sliding sleeve 410 form three contact limiting positions to clamp the slider 300, so that the slider 300 is relatively fixed. This allows the door and window to maintain a stable restricted state in the non-side pressure state, such as during the sliding process or in the stationary state after sliding, thus improving the problem of door and window shaking.

[0046] When the sliding sleeve 410 slides to the other end of the side pressure groove 310, it can be understood that the door and window frame 800 is in a side-pressure state. The side wall of the sliding sleeve 410 abuts against the slider 300, and the slider 300 also abuts against the retaining edge 511 on the same side of the limiting groove 510 of the pressure plate 500 and the corner block 100. This causes the other side wall of the limiting groove 510, i.e., the other two retaining edges 511 on the same side, to form three contact points with the sliding sleeve 410 to clamp the slider 300, making the slider 300 relatively fixed. This can effectively improve the problem of door and window swaying. In particular, when the door and window frame 800 is in a side-pressure state, the sealing strip between the door and window frame 800 and the installation position can help ensure the stability of the door and window and prevent swaying.

[0047] Therefore, the doors and windows can maintain good stability in all states, comprehensively improving the problem of door and window swaying. In other embodiments, the sliding sleeve 410 can be selected to clamp the slider 300 together with the flange 511 only at one end of the side pressure groove 310.

[0048] A clearance through hole 120 is provided on the side of the corner block 100 away from the door and window frame 800. The clearance through hole 120 provides space for the connection operation, i.e. riveting, between the transmission plate 110 and the first joint 700.

[0049] When assembled into the door and window frame 800, the tie rod 400 forms two separate assembly parts with other components. First, the tie rod 400 is slid into the guide groove of the door and window frame 800. Then, the other components, such as the base plate 200, are fixed to the door and window frame 800 with screws. After the base plate 200 and other components are installed on the door and window frame 800, the first joint 700 is connected to the tie rod 400 through the cylindrical block, thus completing the overall assembly.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
