[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0045] Example:
[0046] First embodiment:
[0047] like Figure 1-7 As shown, in this embodiment, a window is provided, which has an anti-falling mechanism, and the anti-falling mechanism includes a first fixing block 1, a second fixing block 2, an anti-falling rope 3 and a height adjustment device;
[0048] One end of the anti-fall rope 3 is connected to the first fixing block 1, and the other end is connected to the height adjustment device
[0049] The height adjustment device is connected to the second fixing block 2 , and has an adjustment end capable of adjusting the relative position between the other end of the anti-fall rope 3 and the second fixing block 2 .
[0050] In this embodiment, see Figure 5 and Figure 7 The first fixed block 1 is connected to the window frame 6 of the window, and the second fixed block 2 is connected to the window sash 5 of the window. The anti-falling mechanism has both anti-falling function and height adjustment function. The relative position between the other end of the anti-falling rope 3 and the second fixed block 2 is adjusted by the adjusting end of the height adjustment device to adjust the length of the anti-falling rope 3 between the first fixed block 1 and the second fixed block 2, so that the height of the window sash 5 relative to the window frame 6 can be adjusted.
[0051] In this embodiment, the specific structure of the height adjustment device is as follows
[0052] Specifically, it is an adjusting sleeve 7, the outer wall of the adjusting sleeve 7 is provided with a threaded portion, and the threaded portion is arranged at the front end position of the outer wall of the adjusting sleeve 7. The threaded portion is the adjusting end of the height adjustment device, and the second fixed block 2 is provided with a threaded hole 201 that matches the thread of the adjusting sleeve 7.
[0053] The principle of the specific adjustment structure is: by adjusting the threaded matching structure between the sleeve 7 and the threaded hole 201, the relative position of the sleeve 7 and the second fixed block 2 can be adjusted, and the height of the sash can be adjusted up and down by adjusting the length of the anti-fall rope 3 between the first fixed block 1 and the second fixed block 2; when the length of the anti-fall rope 3 becomes shorter, the sash 5 will be adjusted upward relatively; when the length of the anti-fall rope 3 becomes longer, the sash 5 will be adjusted downward relatively. The above adjustment structure adopts a threaded adjustment structure. While ensuring convenient adjustment, the threaded matching has a stable connection structure to ensure the stability of the positions of each component after the adjustment is completed.
[0054] In this embodiment, see Figure 3 and Figure 4 The connection structure between the anti-fall rope 3 and the first fixing block 1 and the second fixing block 2 is as follows:
[0055] Specifically, the first fixed block 1 is provided with a first step channel 101 for one end of the anti-falling rope 3 to pass through, and one end of the anti-falling rope 3 is provided with a first end cover 301, and the cross-sectional diameter of the first end cover 301 is larger than the small step channel diameter of the first step channel 101;
[0056] The adjusting sleeve 7 is provided with a second step hole 701 for the other end of the anti-fall rope 3 to pass through, and the other end of the anti-fall rope 3 is provided with a second end cap 302, the cross-sectional diameter of the second end cap 302 is larger than the small step hole diameter of the second step hole 701, and a rivet 702 is provided at the large step hole of the second step hole 701. The rivet 702 provided above plays the role of closing the mouth, and the rivet 702 is provided with a hexagon socket. Because the rivet 702 is connected to the adjusting sleeve 7, the hexagonal wrench can be used to act on the rivet 702 to drive the adjustment of the adjusting sleeve 7 relative to the second fixed position.
[0057] The anti-fall mechanism of this embodiment also has a buffer structure. Specifically, an elastic member sleeved on the anti-fall rope 3 is provided in the second step channel 701, one end of the elastic member abuts against the second end cover 302, and the other end abuts against the inner wall surface of the second step channel 701. The elastic member of this embodiment is a compression spring member 8.
[0058] Through the above buffer structure, during the opening and closing process of the window sash 5, the running trajectory of the anti-fall rope 3 is arc-shaped, and there will be a height difference between the upper and lower parts; the compression spring member 8 at this time makes the running trajectory of the anti-fall rope 3 smooth, thereby ensuring the smoothness of the opening and closing process of the window sash 5.
[0059] At the same time, when the window sash 5 falls downward, the anti-fall rope 3 will pull the window sash 5, thereby preventing the window sash 5 from falling to the ground, and when the anti-fall rope 3 pulls the window sash 5, the second end cover 302 will slide inside the second step channel 701 and squeeze the compression spring component 8, and the compression spring component 8 will be compressed, thereby buffering the pulling force and preventing the anti-fall rope 3 from being broken and damaged due to a large pulling force in a short period of time, thereby improving the use effect of the anti-fall rope 3.
[0060] See also Figure 5 and Figure 6 The specific structure of the connection between the anti-falling mechanism and the window frame 6 of this embodiment is as follows:
[0061] Specifically, a groove 102 is provided on the first fixing block 1, and a tenon block 4 capable of interference fit therewith is provided at the groove 102;
[0062] The matching part of the tenon block 4 and the groove 102 has an upper end 401 and a lower end 402, and a bevel portion 403 matching with the groove 102 is formed between the upper end 401 and the lower end 402 of the tenon block 4, and the cross-sectional size of the upper end 401 of the tenon block 4 is smaller than the cross-sectional size of the lower end 402 of the tenon block 4;
[0063] The first fixing block 1 and the tenon block 4 are provided with self-tapping screws 103 .
[0064] Specifically, a punching screw 202 is provided on the second fixing block 2 .
[0065] The first fixing block 1 and the window frame 6 are fixed in a double manner. In addition to the conventional fixing method of the self-tapping screw 103, a new mortise and tenon structure, namely the tenon block 4, is added. When the self-tapping screw 103 is fixed under force for a long time, the profile hole of the window frame 6 will be deformed, causing the self-tapping screw 103 to loosen, and there is a risk that it cannot be fixed firmly for a long time; the new mortise and tenon structure in this embodiment can effectively solve this problem. The matching part between the tenon block 4 and the groove 102 adopts the wedge structure mentioned above. When the first fixing block 1 is subjected to downward pulling force, the beveled edge 403 of the tenon block 4 can be interference-fitted with the groove 102 of the first fixing block 1, and the force is dispersed to the window frame 6, specifically, the two sides of the C-shaped groove on the window frame 6 that matches the first fixing block 1.
[0066] The anti-falling rope 3 of this embodiment is a steel wire rope.
[0067] The window sash 5 of this embodiment is provided with a C-shaped groove matched with the second fixing block 2. At the same time, the punching screw member 202 on the second fixing block 2 is connected to the window sash 5.
[0068] Second embodiment:
[0069] like Figure 8The difference between the second embodiment and the first embodiment is that in the second embodiment, the outer wall surface of the adjusting sleeve 7 is provided with a threaded portion, and the threaded portion is provided at the tail end position of the outer wall surface of the adjusting sleeve 7, and other structures are the same.
[0070] Third embodiment:
[0071] like Figure 9-10 As shown, the difference between the second embodiment and the third embodiment is that: in the third embodiment, the structure of the hexagonal socket at the large step hole opening of the second step hole 701 has a structural size of the hexagonal socket larger than the size of the large step hole opening, and the rivet structure is eliminated. In addition to playing the role of closing the opening, the above hexagonal socket structure can also drive the adjustment of the adjustment sleeve 7 relative to the second fixed position by using a hexagonal wrench to act on the hexagonal socket structure.
[0072] In summary, the anti-fall mechanism and the window opening thereof in the above embodiments have anti-fall function and height adjustment function. At the same time, the buffer structure provided can ensure the smoothness of the window sash 5 during the opening and closing process and improve the use effect of the anti-fall rope 3. The double fixing method between the anti-fall mechanism and the window frame 6 can also ensure the firmness of the fixation between them.
[0073] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
