Description

Technical Field

[0001] The utility model relates to the technical field of sliding supports, in particular to a flat-opening sliding support structure with stable support. Background Art

[0002] A sliding stay, also known as a stainless steel sliding stay hinge or friction hinge, is a linkage type active link device used to connect window sashes and window frames, allowing the window to be opened and closed smoothly.

[0003] After searching, the patent number CN207228847U discloses a slider support device for casement windows. The device converts the sliding friction between the slider and the side wall of the slide rail into rolling friction by setting four guide wheels. The rolling friction is much smaller than the sliding friction, which improves the smoothness of opening and closing the window. At the same time, the slider is fixed by tightening the positioning screw to complete the positioning of the window sash angle; a sleeve is provided on the hinge screw to improve the smoothness of the rotation of the support rod.

[0004] However, the above structure changes the friction positioning between the original internal slider and the slide rail of the sliding support to a positioning screw that is screwed in and fixed, resulting in a smaller angle range for the window to be opened by the sliding support. At the same time, when the sliding friction is small, the sliding support is prone to cause the window sash and window frame to collide quickly and make a loud noise when it moves back quickly, thereby reducing the effectiveness of the sliding support. Utility Model Content

[0005] In view of the problems existing in the existing stable flat-opening sliding support structure, the present utility model is proposed.

[0006] Therefore, the utility model aims to provide a stable sliding support structure for opening sideways, which solves the problem that the expansion angle of the window sash driven by the sliding support is fixed and effective buffering cannot be performed during rapid return movement.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A plurality of positioning holes arranged at intervals are provided inside the supporting cantilever, and a positioning rod is provided on the outer wall of the extending cantilever via a rotating mechanism, and the end of the positioning rod is inserted into the positioning hole.

[0010] Preferably, the sliding buffer mechanism comprises a slider, the slider is slidably disposed in the guide hole, and an end portion is fixedly connected to the first connecting rod, and a buffer spring is fixedly disposed between the slider and the inner wall of the guide hole.

[0011] Preferably, the rotating mechanism includes a fixed rod, which is fixedly mounted on the outer wall of the extended cantilever, and a rotating shell is rotatably sleeved on the rod wall, a cross rod is fixedly mounted on the inner wall of the rotating shell, and the positioning rod is rotatably sleeved on the outer side of the cross rod, both ends of the cross rod are sleeved with torsion springs, and the two ends of the torsion spring are respectively fixedly connected to the rotating shell and the positioning rod.

[0012] Preferably, the outer wall of the support plate is sleeved with a corrugated limiting tube, and two ends of the corrugated limiting tube are respectively fixedly connected to the slider and the support plate.

[0013] Furthermore, the cross section of the sliding block is arranged in an "I" shape.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a horizontally-opened sliding support structure with stable support.

[0026] Example 1

[0027] The utility model provides Figure 1-3 A stable supporting flat-opening sliding support structure shown includes a slide rail plate 1 and a slide rail groove opened on the surface of the slide rail plate 1, a support rod 2 is fixedly provided on the inner wall of the slide rail groove, a protruding cantilever 3 is rotatably sleeved on the rod wall of the support rod 2, a support plate 4 is fixedly provided on the end of the inner wall of the slide rail groove away from the support rod 2, a guide hole is opened on the upper end of the support plate 4, a first connecting rod 5 is provided inside the guide hole through a sliding buffer mechanism, a second connecting rod 6 is fixedly penetrated inside the protruding cantilever 3, a support cantilever 7 is rotatably sleeved between the first connecting rod 5 and the second connecting rod 6, the sliding buffer mechanism includes a slider 10, the cross-section of the slider 10 is arranged in an "I" shape, the slider 10 is slidably arranged in the guide hole, and the end portion is fixedly connected to the first connecting rod 5, and a buffer spring 11 is fixed between the slider 10 and the inner wall of the guide hole.

[0028] When the sliding support is in use, the extended cantilever 3 can be extended from the slide rail groove through the support of the support rod 2. At this time, under the support of the first connecting rod 5 and the second connecting rod 6, the supporting cantilever 7 can be unfolded, and the slider 10 can slide in the guide hole of the support plate 4. At this time, the buffer spring 11 is stretched, and the sliding cooperation between the slider 10 and the guide hole can make the sliding support drive the window sash to be easily unfolded. When the sliding support is closed and drives the window sash and the window frame to close, the slider 10 moves back and squeezes the buffer spring 11. Under the buffering action of the buffer spring 11, the impact caused by the rapid return movement can be offset, and the window sash can be avoided from hitting the window frame with a loud sound as much as possible, thereby improving the versatility of the sliding support.

[0029] Example 2

[0030] Embodiment 2 is based on embodiment 1. In order to extend the cantilever 3 and support the cantilever 7 after it is unfolded, the support position of the extended cantilever 3 can be fixed, such as Figure 1-3 As shown, a plurality of positioning holes 8 arranged at intervals are opened inside the supporting cantilever 7, and a positioning rod 9 is provided on the outer wall of the extended cantilever 3 through a rotating mechanism, and the end of the positioning rod 9 is inserted into the positioning hole 8. The rotating mechanism includes a fixing rod 12, and the fixing rod 12 is fixedly arranged on the outer wall of the extended cantilever 3, and a rotating shell 13 is rotatably sleeved on the rod wall, and a cross bar 14 is fixedly arranged on the inner wall of the rotating shell 13, and the positioning rod 9 is rotatably sleeved on the outer side of the cross bar 14, and torsion springs 15 are sleeved on both ends of the cross bar 14, and the two ends of the torsion spring 15 are respectively fixedly connected to the rotating shell 13 and the positioning rod 9, and the support plate 4 and the positioning rod 9 are respectively an L-shaped support plate and an L-shaped positioning rod.

[0031] Before the extended cantilever 7 is extended, the positioning rod 9 can be lifted so that the positioning rod 9 rotates around the cross bar 14 and twists the torsion spring 15. After the extended cantilever 3 drives the supporting cantilever 7 to unfold, the positioning rod 9 is rotated to the positioning hole 8 at the corresponding position through the relative rotation of the rotating shell 13 and the fixing rod 12, and the positioning rod 9 is released. Under the torsion recovery of the torsion spring 15, the positioning rod 9 can rebound and be inserted into the positioning hole 8. At this time, in the stable triangular state formed by the positioning rod 9, the extended cantilever 3 and the supporting cantilever 7, the supporting position of the extended cantilever 3 can be fixed to ensure stable support for the window sash.

[0032] Example 3

[0033] Embodiment 3 is based on Embodiment 1 to fix the buffer position of the buffer spring 11. Figure 1 As shown, the outer wall of the support plate 4 is sleeved with a corrugated limit tube 16 , and both ends of the corrugated limit tube 16 are fixedly connected to the slider 10 and the support plate 4 respectively.

[0034] The corrugated limit tube 16 wraps the support plate 4, which can prevent the buffer spring 11 from bending and passing through the guide hole when the slider 10 squeezes the buffer spring 11, limit the position of the buffer spring 11, and also effectively offset the impact of the rapid return of the sliding support.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
