Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to a component for supporting the suspension of doors and windows. Background Art

[0002] Lifting windows are different from traditional inward opening, outward opening and ordinary push-pull modes. Instead, they are opened by lifting and pulling up and down. They have beautiful lines and wide viewing angles. They do not collide with the human body when opened. The window sash is wrapped in the frame and has no hidden danger of falling outward. They have excellent safety factors and many other advantages. They are widely used in high-rise buildings in North America. Existing lifting windows and folding windows are generally opened or closed by manual or electric control. However, when opened by manual control, the lifting device cannot stop the lifting window or folding window sash at any height, and there is a problem that the lifting balancer cannot stop the lifting window and folding window at any height.

[0003] To this end, a lifting balancer with the announcement number "CN109458081B" includes a slider and a coil spring seat, the slider can slide in the window frame, the coil spring seat is wound with a coil spring, the coil spring seat is connected to the slider through the coil spring, and the coil spring is used to pull the slider to slide in the window frame; a through hole is provided in the middle of the slider, and a rotating block that can rotate in the through hole is provided in the through hole, the shape of the rotating block is elliptical, and the distance between the upper end and the lower end of the rotating block is greater than the distance between the left end and the right end of the rotating block; limiting components are provided on the left and right sides of the slider, and the limiting components can be protruded outward by rotating the rotating block. The lifting balancer of the present invention pulls the slider to slide in the window frame by the coil spring, and the limiting components on the left and right sides of the slider are protruded outward by rotating the slider, and the slider is fixed on the window frame, which solves the problem that the lifter in the prior art cannot stop the lifting window or the up-and-down folding window at any height.

[0004] However, for the above-mentioned lifting balancer, although a coil spring is wound on the coil spring seat and the coil spring seat is fixed on the window frame, the coil spring seat can be stretched or retracted to achieve the sliding of the slider in the window frame through the coil spring. However, there are still the following obvious defects during use: when the coil spring is pulled out quickly, it will expand due to the inertia generated by the pulling out of the coil spring and get stuck on the arc-shaped spacer block provided between the coil springs, thereby causing the coil spring to get stuck and unable to be pulled out through the slider. Summary of the invention

[0005] The purpose of the utility model is to provide a member for supporting door and window suspension to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a member for supporting door and window suspension, comprising:

[0007] A base, wherein four coil spring members movably sleeved by a rotating shaft are equidistantly arranged on the surface of the base, and two positioning blocks are symmetrically arranged between the coil spring members for preventing the coil spring sheets on the coil spring members from getting stuck and for positioning the coil spring members on the upper end surface of the base;

[0008] A fixed block is movably arranged at one end of the base and is provided with a docking slot, a side surface of the fixed block is provided with a coil spring sheet hole connected to the coil spring sheet in the coil spring member at one end of the base, and a rotating block is installed on one side of the upper end surface of the fixed block.

[0009] Preferably, one end of the four coil spring members is provided with a limit clamp, and the four coil spring members are movably connected to each other through the limit clamp, and a circular wear-resistant gasket is provided on one side of the four coil spring members corresponding to the base, so that the coil spring members can protect the base and the inner groove of the window frame through the wear-resistant gasket when being clamped out and retracted, thereby avoiding the problem of serious friction between the coil spring members.

[0010] Preferably, a trapezoidal limiting plate is fixed on one side of the fixed block at one end of the base, and limiting vertical plates are provided on both sides of the lower end surface of the limiting plate, and the limiting plate and the limiting vertical plates are combined to form a limiting plug block, and the base is inserted into the docking slot through the limiting plug block and combined with the fixed block to limit the base, so that the base can be docked and combined with the docking slot on the fixed block through the limiting plug block, and by providing four coil spring members, the elastic retraction force can be increased to accurately allow the window frame to be hovered and positioned when moving.

[0011] Preferably, both surfaces of the positioning block are arc-shaped surfaces, and a semicircular groove is provided on the arc-shaped surface. A ball is movably provided in the semicircular groove, which is beneficial to the smooth retraction and release of the coiled spring piece in the coiled spring component. When the coiled spring piece in the coiled spring component is pulled out, the contact friction with the arc-shaped surface of the positioning block can be reduced, thereby reducing the occurrence of the coiled spring piece getting stuck.

[0012] Preferably, the end of the fixed block is provided with a concave hole position which is a combination of two semicircles, and the rotating block is rotatably set in the concave hole position, and a limiting clamp is installed on one side of the concave hole position, and one end of the limiting clamp is connected with the coil spring sheet hole position, so that the coil spring sheets in the four coil spring members can be interactively connected to each other, and the coil spring sheet in one of the coil spring members can be inserted into the coil spring sheet hole position and fixed by the limiting clamp.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the door and window suspension supporting member is provided with coil spring members arranged at equal intervals on the base through a rotating shaft, and a positioning block with an arc-shaped surface is provided between the four coil spring members, and a ball bearing is movably embedded in the arc-shaped surface, and a coil spring piece in one of the coil spring members is connected to the fixed block, so that when the fixed block uses the movable window frame to pull the coil spring piece in the coil spring member to change the angle and position of the movable window frame to suspend, the coil spring pieces in the four coil spring members are pulled out collectively through the arc-shaped surface in the positioning block, and the coil spring pieces ..., and the coil spring pieces are pulled out collectively through the arc-shaped surface in the positioning block, and the coil spring pieces are pulled out collectively, and the coil spring pieces are pulled out collectively When the spring leaf is pulled out, its surface contacts the ball embedded in the curved surface, thereby preventing the spring leaf from expanding inertia and increasing its diameter when being pulled out and rolled up, causing it to get stuck due to friction with the curved surface in the positioning block. The movably connected fixed block can make the movable window frame hover more smoothly and arbitrarily. By increasing the number and weight of the spring leaves, the lifting balancer is more precise than that of the comparison file, and multiple spring leaves will cause poor window limiting. Now, multiple spring leaves are interconnected without redundant spring leaves, making the window opening and closing hovering more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 The utility model provides a technical solution: a member for supporting door and window suspension, comprising:

[0023] The base 1 is fixed to the window frame. By stretching or retracting, the base 1 can pull the fixed block 5 to slide in the window frame through the coil spring sheet. The surface of the base 1 is equidistantly provided with four coil spring members 3 movably sleeved by the rotating shaft 2, and the coil spring sheet is wound in the coil spring member 3, and the coil spring sheet is wound through the winding shaft, and the winding shaft is movably sleeved on the rotating shaft 2 set at the end of the base 1. Two positioning blocks 4 for preventing the coil spring sheet on the coil spring member 3 from getting stuck and positioning the coil spring member 3 on the upper end surface of the base 1 are symmetrically provided between the coil spring members 3, which can be used to isolate and limit the coil spring sheets wound in the four coil spring members 3 to avoid the coil spring members 3 being stuck due to large friction. The coil spring sheet is used to pull the fixed block 5 to slide in the window frame;

[0024] A fixed block 5 is movably arranged at one end of the base 1 and is provided with a docking slot 6, so that the fixed block 5 can be accurately docked with one end of the base 1 through the docking slot 6 when it slides in the window frame to return to its initial state. A coil spring hole 7 connected to the coil spring in the coil spring member 3 at one end of the base 1 is provided on one side of the fixed block 5, so that one end of the coil spring in one of the coil spring members 3 can be inserted into the coil spring hole 7. A rotating block 8 is installed on one side of the upper end surface of the fixed block 5. When the fixed block 5 slides in the window frame, the rotating block 8 can be rotated to make the limiting components respectively arranged on the left and right sides of the fixed block 5 protrude outward, thereby realizing opening or closing the window.

[0025] A limiting clamp 9 is provided at one end of the four coil spring members 3, and the four coil spring members 3 are movably connected to each other through the limiting clamp 9, and a strip-shaped movable groove is provided at a position away from the limiting clamp 9, so that the coil spring members 3 have a certain movable buffer, so that the coil spring sheets are neatly overlapped and combined, and a circular wear-resistant gasket 10 is provided on one side of the four coil spring members 3 corresponding to the base 1, so that the coil spring members 3 can reduce friction with the surface of the base 1 while being pulled out and retracted, and a trapezoidal limiting plate 11 is fixed on one side of the fixing block 5 at one end of the base 1, and the limiting plate 11 can be fixed on the fixing block 5 After sliding recovery, it is combined with the base 1 to realize the opening or closing of the window frame. The lower end surface of the limit plate 11 is provided with limit vertical plates 12 on both sides, so that the limit plate 11 can be combined with the docking slot 6 after the fixed block 5 is combined with one end of the base 1 to ensure the stability of the combination, and the limit plate 11 and the limit vertical plate 12 are combined to form a limit plug block, and the base 1 is inserted into the docking slot 6 through the limit plug block and is limitedly combined with the fixed block 5, so that when the window frame is closed, the fixed block 5 slides close to one end of the base 1 in the slot box of the window frame, and the docking slot 6 is used to perform a docking and limiting combination with the limit plate 11.

[0026] The two surfaces of the positioning block 4 are both arc-shaped surfaces, and a semicircular embedding groove 16 is provided on the arc-shaped surface, so that the ball 13 can be movably embedded in the semicircular embedding groove 16, so that the ball 13 can rotate along with the pulling out and winding of the winding spring piece. The movable ball 13 in the semicircular embedding groove 16 is conducive to the smooth retraction and release of the winding spring piece in the winding spring member 3, and the ball 13 can be in contact with one side of the winding spring piece, which is conducive to smoother pulling out and winding of the winding spring piece. The end of the fixed block 5 is provided with a concave hole position 14 composed of two semicircles, which allows the rotating block 8 to rotate in the concave hole position 14 to limit the fixed block 5 in the inner groove of the window frame. The rotating block 8 is rotatably set in the concave hole position 14, and a limiting clamp 15 is installed on one side of the concave hole position 14. One end of the limiting clamp 15 is connected with the winding spring piece hole position 7, which is conducive to the connection between one end of the winding spring piece and the fixed block 5. At the same time, the fixed block 5 can slide in the inner groove of the window frame through the elasticity of the winding spring piece.

[0027] Specifically, when in use, the coil spring piece in the coil spring member 3 pulls the fixed block 5 to slide in the window frame, and the sliding of the fixed block 5 in the inner groove of the window frame drives the coil spring pieces connected to each other in the four coil spring members 3 to be pulled out. When the coil spring pieces are pulled out, the coil spring member 3 rotates on the rotating shaft 2. The wear-resistant gasket 10 provided on the base 1 can reduce the friction between the coil spring piece and the surface of the base 1. Under the action of the continuous pulling of the coil spring member 3, the coil spring piece slides in the arc surface in the positioning block 4, and the coil spring piece slides on the ball 13 By increasing the distance between the positioning block 4 and the winding spring piece, and continuously pulling out and winding up the window frame back and forth to open and close the window frame, the winding spring piece 3 will not be stuck on the positioning block 4 due to the increase in diameter due to the inertia of rotation, thereby causing the winding spring piece 3 to be stuck. By increasing the number and weight of the winding spring piece 3, the lifting balancer is more accurate than the comparison document, and multiple winding spring pieces will cause poor window limiting. Now that multiple winding spring pieces 3 are interconnected without redundant winding spring pieces 3, the window opening and closing suspension is more stable.
