Abstract

This invention relates to a sliding structure and a sliding window including the sliding structure, belonging to the field of building door and window technology. It includes: a fixed groove, a movable groove, and a driving rack. A rotating shaft is rotatably connected to the bottom of the fixed groove. The top and bottom ends of the rotating shaft extend into and out of the fixed groove, respectively, and are fixed with an upper gear and a lower gear. The movable groove is placed inside the fixed groove, and a driven rack is fixed to its bottom surface, meshing with the upper gear. The driving rack meshes with the lower gear.

Furthermore, the meshing connection between the driven gear and the upper gear allows the movable groove to reciprocate along the width direction of the fixed groove, thereby pressing against or moving away from the fixed groove without moving along its length, improving the convenience and tightness of the movable groove pressing against the fixed groove.

Description

Technical Field

[0001] This invention relates to the field of building door and window technology, and particularly to a sliding structure and a sliding window including the sliding structure. Background Technology

[0002] Sliding windows and casement windows each have their advantages and disadvantages. Casement windows, due to their squeeze-to-close mechanism, offer better sealing compared to sliding windows. However, they occupy indoor and outdoor space, have a smaller opening, and suffer from poor ventilation. They are also less likely to cause head injuries to playful children, are not ideal for curtains, and pose a risk of being blown off by strong winds. On the other hand, sliding windows offer good ventilation, do not occupy any indoor or outdoor space, and are safer than casement windows, eliminating the risk of window sashes being blown off by strong winds. They have greater market application potential than casement windows, but their disadvantages include poorer sealing, sound insulation, and heat insulation compared to casement windows.

[0003] To improve the sealing performance of sliding windows, several sliding window technologies with inward and outward sliding pulley structures have been introduced to enhance their sealing. Existing sliding window technologies fall into two categories. One type uses sliding pulleys for positioning, with the window sliding and closing via a zigzag or oblique straight groove guide block moving left and right. The disadvantages of this type are low precision during sliding, hard friction between the guide rivets and guide blocks, and generally poor handle feel. Furthermore, it can only slide a certain distance, making it difficult to adjust the sliding distance easily. Long-term sliding and pressing cause wear on the sliding pulleys. Since only the sliding pulleys serve as positioning points for sliding and pressing to close the window, the non-perpendicular gap between the main body and the sliding body can significantly affect the handle feel, especially with heavy glass, resulting in a generally heavy feel. Sliding windows using this technology typically slide a maximum distance of 5-6 millimeters during sliding, but this distance is significantly reduced to less than 5-6 millimeters after wear and tear on the guide blocks and guide rivets, thus negating the purpose of the sliding effect.

[0004] The second method uses window sash locking rods and latches to achieve overall sliding and track changing of the door and window sashes. This technology has very obvious drawbacks. It relies entirely on the hard friction between the locking points and locking rods to slide and squeeze the window to close. Moreover, the locking rods cannot fit tightly in the groove of the window sash, which will create gaps and greatly reduce the sliding distance. Long-term use of hard friction between the locking rods and latches will cause wear on the locking rods and latches, which will create certain gaps and lose the sealing effect. It also requires very high precision in installing the locking points, and multiple locking points are needed to achieve the sliding effect. The central column locking point is costly and the effect is not ideal.

[0005] Therefore, how to design a simple, well-sealed, frictionless, unrestricted, and highly precise translational sliding structure is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] This invention provides a translational sliding structure that solves the problems of hard friction, poor grip feel, and short translational distance in existing translational sliding structures. The technical solution of this invention to solve the above-mentioned technical problems is as follows: a translational sliding structure, comprising:

[0007] A fixed groove body is provided with a through hole at the bottom of the groove body. A rotating shaft is rotatably connected to the through hole and its rotation axis is parallel to the height direction of the fixed groove body. The top end of the rotating shaft extends into the fixed groove body and is fitted with an upper gear, and its bottom end extends out of the fixed groove body and is fitted with a lower gear.

[0008] A movable trough is placed inside a fixed trough along its length and the two are provided with a preset moving distance along their width. A driven rack is fixed on its bottom surface. The driven rack meshes with an upper gear and drives the movable trough to reciprocate along the width of the fixed trough as the upper gear rotates. Multiple sliding wheels are rotatably connected at intervals along the length of the movable trough to support the part to be moved. The rotation axes of the multiple sliding wheels are all parallel to the width of the movable trough.

[0009] An active rack is positioned parallel to the bottom of the fixed groove and moves back and forth along the length of the fixed groove. The active rack meshes with the lower gear.

[0010] The beneficial effects of this invention are as follows: Since the active rack, which reciprocates along the length of the fixed groove, meshes with the lower gear, it can simultaneously drive the lower gear, the rotating shaft, and the upper gear to rotate. Furthermore, since the driven gear, fixed to the bottom of the movable groove along the width of the fixed groove, meshes with the upper gear, it can drive the movable groove to reciprocate along the width of the fixed groove. Thus, without moving along the length of the fixed groove, the movable groove is moved closer to or further away from the fixed groove along the width of the fixed groove, replacing the traditional Z-shaped squeezing method of the movable groove approaching or moving away from the fixed groove. This simplifies the mechanical structure of the translational sliding structure and improves the convenience and tightness of the movable groove squeezing the fixed groove.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the bottom of the movable groove is provided with a mounting hole, and the driven rack is fixed on the inner wall of the mounting hole along the width direction of the movable groove.

[0013] The further beneficial effect of adopting the above is that by fixing the driven rack to the inner wall of the mounting hole, it is possible to avoid the upper gear that meshes with the driven rack from colliding with the bottom of the moving groove, thereby improving the smoothness of the movement of the moving groove.

[0014] Furthermore, it also includes a limiting wheel. A strip is fixed to the outer wall of the moving trough in the width direction. The limiting wheel is rotatably connected to the end of the strip away from the moving trough and its rotation axis is parallel to the height direction of the moving trough.

[0015] The further beneficial effect of adopting the above is that the limiting wheel can abut against the side wall of the door frame slide rail after the moving groove and the fixed groove are squeezed together, thereby playing an auxiliary role in the translation of the pulley during the squeezing and translation process, and always ensuring that the moving groove and the fixed groove are in a parallel state to reduce the wear of the pulley.

[0016] Furthermore, it also includes guide posts, which are arranged along the width direction of the fixed groove and whose two ends are respectively fixed on the two opposite inner groove walls of the fixed groove; the two opposite groove walls of the movable groove are provided with guide holes, which are slidably connected to the guide posts along the axis of the guide posts to guide the movement direction of the movable groove.

[0017] The further beneficial effect of adopting the above is that by using the guide hole of the movable groove to slide on the guide post, the moving direction of the movable groove can be guided, thereby improving the compactness of the translational sliding structure and the smoothness of translation.

[0018] Additionally, a sliding window with a sliding structure is provided, comprising: an outer window frame, an inner window frame, a sliding structure, a corner mechanism, and a handle. A slide rail is fixed to the inner top or bottom surface of the outer window frame; the inner window frame is parallel to and located inside the outer window frame; a fixing groove is fixed to the outer top or bottom surface of the inner window frame along its length, and multiple sliding wheels are slidably connected within the slide rail along its length; the corner mechanism is located inside the outer window frame and fixed at the corner of the inner window frame, one end of the corner mechanism is connected to the active rack and pinion and pulls the active rack to reciprocate along the length of the fixing groove; the handle is rotatably connected to the inner window frame and is connected to the other end of the corner mechanism.

[0019] The further beneficial effects of the above are as follows: First, the fixed groove is fixed to the bottom or top surface of the inner window frame, and then the sliding wheel of the movable groove is slidably connected to the slide rail of the outer window frame. When the handle is turned to drive the cornering device, one end of the cornering device will pull the active rack to drive the outer groove wall of the movable groove to squeeze the inner groove wall of the fixed groove, thereby locking the inner window frame in any position of the outer window frame and improving the sealing performance between the inner and outer window frames.
