[0023] See also Figures 1-7 , which are schematic diagrams of the structure of the window sash anti-falling assembly of the utility model and its application scenarios and working effects.
[0024] As shown in the figure, an embodiment of the utility model provides a window sash anti-falling component, whose overall structure includes a steel groove 10, a slider 9, a steel rope 7, a steel rope lock 3 and an elastic device, wherein the elastic device includes a spring seat 6 and a spring 5, wherein the spring seat 6 is fixedly mounted on the sash edge, and one end of the spring 5 abuts against the inner side of the spring seat 6, wherein the slider 9 is arranged in the slide groove of the steel groove 10 and can slide relatively, and the steel groove 10 is mounted on the inner groove of the window frame, one end of the steel rope 7 is fixedly connected to the slider 9, and the other end is straightened and extended and passes through the spring seat 6 and the spring 5, and the steel rope lock 3 at the other end of the steel rope 7 abuts against the other end of the spring 5, and the steel rope lock 3 and the elastic device are limited in the sash edge, and during the opening process of the window sash, the steel rope 7 and the slider 9 move with the opening of the window sash, thereby pulling the compression spring 5, and lifting the window sash under the reverse force of the spring 5.
[0025] Among them, in a possible implementation, the window sash anti-falling assembly also includes a through tube 13, which is fixedly installed in the profile of the sash edge, and the elastic device and the steel rope lock 3 are both limited in the through tube 13.
[0026] In a possible implementation, the elastic device further includes an elastic force stopping block 2 , which is disposed at the outer end of the steel rope lock head 3 and fixedly installed in the through tube 13 .
[0027] In a possible implementation, the elastic force stopping block 2 is locked and fixed in the through tube 13 by the elastic force stopping screw 12 passing through the elastic force stopping block 2 .
[0028] In a possible implementation, a pipe plug 1 is further provided on the end of the through pipe 13 away from the spring seat 6 .
[0029] Among them, in a possible implementation, an adapter seat 4 is also sleeved on the wire rope lock head 3.
[0030] Among them, in a possible implementation, one end of the wire rope 7 is riveted to the slider 9 through a wire rope rivet 8.
[0031] Among them, in a possible implementation, the steel groove 10 is fixedly installed on the inner groove of the window frame through self-tapping screws 11.
[0032] Based on the structural composition of the window sash anti-falling component of the present utility model, the installation of the product will be further introduced in combination with this structure:
[0033] Frame side installation: Place the slider 9 into the steel groove 10, and use self-tapping screws 11 to fix the steel groove 10 at the inner groove of the frame side.
[0034] Sash side installation: Open the window sash, straighten the wire rope, install the through-hole pipe on the sash side of the window sash, and use self-tapping screws 11 to fix the spring seat 6 and the pipe plug 1 respectively, so as to completely fix the through-hole pipe 13 including the internal structure in the window sash slot. As Figure 5 shown.
[0035] After the installation is completed, screw out the elastic stop screw 12. At this time, the elastic stop block 2 is in a free state and can slide. Therefore, after the elastic stop screw 12 is taken out, the spring 5 is in a state of releasing elastic force, and the direction of the elastic force is as shown by the arrow direction in Figure 5 the figure. The wire rope 7 is riveted to the wire rope lock head 3 and the wire rope rivet 8. On the side of the wire rope lock head 3, the wire rope 7 is in a stressed state under the action of the spring 5, and the wire rope rivet 8 is riveted to the slider 9. The slider 9 is installed in the steel groove 10, and the steel groove 10 is fixed on the window frame. Therefore, the wire rope 7 is in a taut and stressed state.
[0036] Since the spring 5 inside the through-hole pipe has released elastic force, under the action of action and reaction, the window sash is pulled by the wire rope 7, and the window sash is lifted to play a role in preventing sagging; the stressed state of the components during operation can pull the window sash, and under the action of the components, the window will not be damaged by the wind pressure blowing the hinge hardware to damage the window sash, because it plays a buffering role under the action of the spring 5 inside the device; even if the hinge hardware of the window sash breaks or the window sash is on the verge of falling in extremely bad weather, under the action of this device, it can protect the window sash from falling and play the anti-falling function effect.
[0037] Many load-bearing components of casement windows are hinges (sliding supports). The window sash has a certain opening stroke. Once the opening stroke of the hinge (sliding support) is too large and greater than the compression stroke of the spring, the spring cannot play a role and instead limits the opening angle of the window sash.
[0038] Based on the structural design of the anti-falling component of the present utility model, it can move along the hinge track. No matter how large the opening angle is, the slider 9 will move in the steel groove 10 along with the hinge movement track.
[0039] During the opening process of the window sash, the opening stroke of the hinge (sliding brace) is getting larger and larger. The through-tube is fixed on the window sash, and all the parts inside the through-tube move along with the opening of the window sash, that is, the steel rope also moves accordingly. Thus, the steel rope pulls the slider, and the slider slides in the steel groove, that is, the component moves along with the hinge track. Under the action of the spring, at any moment, it acts on the window sash, lifts the window sash, and reduces the load-bearing of the hinge (sliding brace). See Figure 7 (Window sash half-opened) to Figure 6 (Window sash fully opened) process.
[0040] During the closing process of the window sash, the closing stroke of the hinge (sliding brace) is getting smaller and smaller. The through-tube is fixed on the window sash, and all the parts inside the through-tube move along with the opening of the window sash, that is, the steel rope also moves accordingly. Thus, the steel rope pulls the slider, and the slider slides in the steel groove, that is, the component moves along with the hinge track. Under the action of the spring, at any moment, it acts on the window sash, lifts the window sash, and reduces the load-bearing of the hinge (sliding brace). See Figure 6 (Window sash fully opened) to Figure 7 (Window sash half-opened) process.
[0041] Based on the above detailed description of the window sash anti-falling component in combination with the drawings of the present utility model, it can be understood that the window sash anti-falling component of the present utility model includes a steel groove, a slider, a steel rope, a steel rope lock head, and an elastic device. The elastic device includes a spring seat and a spring. The spring seat is installed on the sash edge. One end of the spring abuts against the inner side of the spring seat. The slider is arranged in the chute of the steel groove and can slide relatively. The steel groove is installed on the inner groove of the window frame. One end of the steel rope is riveted on the slider, and the other end is straightened and extends through the spring seat and the spring. And the steel rope lock head at the other end of the steel rope abuts against the other end of the spring. During the opening process of the window sash, the steel rope and the slider move along with the opening of the window sash, thus pulling and compressing the spring. Under the reverse acting force of the spring, the window sash is lifted, and the load-bearing of the hinge is reduced. The built-in spring plays a buffering and force-resistant role, consumes the fatigue of the hinge structure, resists the weight of the window sash and the wind pressure, and prevents the window sash from sagging. When opening and closing, the window sash is smooth and has no resistance.
[0042] Even if the hinge is damaged or the installation screw comes off, causing the window sash to fall, the tensile force of the steel rope can prevent the window sash from falling and reduce the accident risk.
[0043] Since some components of the component can move along with the hinge track, it ensures that hinges with large opening stroke dimensions can also be used, acting on the window sash and lifting the window sash at all times, and reducing the load-bearing of the hinge.
[0044] Moreover, the components of the present utility model are conveniently installed without damaging the window body, and installation without milling slots is facilitated, which is conducive to replacement and maintenance. In addition, this component can be installed on both new and old window sashes, which belongs to post-installation and does not require window removal.
[0045] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
