Technical Field
[0001] The utility model relates to the technical field of door and window accessories, in particular to an anti-falling rope for doors and windows. Background Art
[0002] Doors and windows are divided into enclosing components or partition components according to their location. They have different design requirements and must have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fire prevention. In order to increase the risk of windows falling, anti-fall ropes will be installed on doors and windows.
[0003] After searching the patent number CN218542093U, it is specifically a new type of anti-fall rope used for doors and windows. The structure is simple, the production cost is low, and it is easy to mass produce. When the window is closed, the wire rope will move directly downward along the original trajectory, so that the end will no longer be clamped by the window. It also has better safety performance and can withstand greater tension than a single screw fixing method.
[0004] Although the above patent can prevent the end from being clamped by the window, and the U-shaped plate can improve the pulling force and safety, it is inconvenient to install by drilling holes in the window frame and the inner cavity of the window sash and installing it with screws. Secondly, a single screw may become loose after installation. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides an anti-fall rope for doors and windows, which solves the problem of drilling holes in the inner cavity of window frames and window sashes and installing them with screws during installation, which is inconvenient to install. Secondly, a single screw may become loose after installation.
[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: an anti-fall rope for doors and windows, comprising a window frame and a window sash, wherein an anti-fall rope is arranged between the window frame and the window sash.
[0007] The anti-fall rope includes a steel wire rope, and the upper and lower ends of the steel wire rope are respectively slidably sleeved with a lower connecting block and an upper connecting block, the upper connecting block is fixedly installed with a hook by screws, and a small connecting block is fixedly installed on the surface of the hook by screws, one end of the steel wire rope is movably sleeved with a spring, the two ends of the steel wire rope are larger than the inner cavity diameters of the upper connecting block and the lower connecting block, and the lower connecting block is fixedly installed with a limit block by screws.
[0008] Preferably, the inner cavities of the upper connecting block and the lower connecting block are countersunk holes, and the spring is located in the inner cavity of the lower connecting block.
[0009] Preferably, the hook is L-shaped and is snap-fitted into the inner cavity of the window frame.
[0010] Preferably, the small connecting block and the upper connecting block are in contact with each other and are flush with each other.
[0011] Preferably, the clamping angle and the limiting block of the lower connecting block are slidably sleeved in the inner cavity of the window sash.
[0012] Preferably, the window frame and the window sash are assembled with each other. Beneficial Effects
[0013] The utility model provides an anti-falling rope for doors and windows. Compared with the prior art, it has the following beneficial effects:
[0014] The anti-fall rope for doors and windows is hooked and clamped at the corner of the inner cavity of the window frame, and then the clamping corners of the small connecting block and the upper connecting block can also slide in the inner cavity of the window frame, and then the hook is fixed by screws. The two fixations of the hook clamping and the screw make the connection more stable and prevent loosening. Then the clamping corner of the lower connecting block and the limit block are slidably sleeved into the inner cavity of the window sash to complete the assembly. Therefore, the lower end does not need to be installed through opening holes and screws, and the clamping of the hook makes the installation convenient.
[0015] 2. The anti-fall rope for doors and windows can also be telescopically slid in the inner cavity of the window sash according to the opening and closing angle of the window sash through the lower connecting block and the limit block, thereby not affecting the opening and closing angle of the window sash.

[0025] 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.
[0026] See also Figure 1-4 The utility model provides a technical solution: an anti-fall rope for doors and windows, comprising a window frame 1 and a window sash 2, an anti-fall rope 3 is arranged between the window frame 1 and the window sash 2, the window frame 1 and the window sash 2 are assembled with each other, wherein the window frame 1 is installed on the window, and then the window sash 2 is rotatably connected to the window frame 1, and the anti-fall rope 3 is connected to the window frame 1 and the window sash 2, and finally the window is installed on the window sash 2.
[0027] See also Figure 5-8 ,
[0028] The anti-fall rope 3 includes a steel wire rope 31, and the upper and lower ends of the steel wire rope 31 are slidably sleeved with a lower connecting block 32 and an upper connecting block 36 respectively. The upper connecting block 36 is fixedly installed with a hook 34 by screws, and a small connecting block 33 is fixedly installed on the surface of the hook 34 by screws. One end of the steel wire rope 31 is movably sleeved with a spring 37, and the spring 37 can play a buffering role. The two ends of the steel wire rope 31 are larger than the inner cavity diameters of the upper connecting block 36 and the lower connecting block 32, so that the steel wire rope 31 can be prevented from falling off from the inner cavities of the lower connecting block 32 and the small connecting block 33.
[0029] The lower connecting block 32 is fixed with the limit block 35 by screws, and one end of the lower connecting block 32, the upper connecting block 36 and the small connecting block 33 are extended with a clamping angle. Since the clamping angle of the lower connecting block 32 and the limit block 35 form the left and right sides, they can be slidably connected to the inner cavity of the window sash 2, and the clamping angles of the upper connecting block 36 and the small connecting block 33 can also slide in the inner cavity of the window frame 1.
[0030] The hook 34 is L-shaped and is snap-fitted into the inner cavity of the window frame 1 . The L-shaped hook 34 can be snap-fitted into the corner of the inner cavity of the window frame 1 .
[0031] When in use, after the hook 34 is snap-fitted into the corner of the inner cavity of the window frame 1, the corners of the small connecting block 33 and the upper connecting block 36 can also be slid in the inner cavity of the window frame 1, and then the hook 34 is fixed by screws. The two fixations of the hook 34 and the screws make the connection more stable and prevent loosening.
[0032] Then, the lower connecting block 32 is slidably sleeved into the inner cavity of the window sash 2 through the clamping angle and the limit block 35 to complete the assembly, and the lower end does not need to be installed through the opening and screws, and the installation is convenient during installation through the clamping of the hook 34. Then, the window sash 2 is assembled with the window frame 1. When the window sash 2 is opened and rotated on the window frame 1, the wire rope 31 will be pulled out from the inner cavity of the window frame 1 and the window sash 2 to form an inclined line. At the same time, when the wire rope 31 is pulled, its spring 37 can play a buffering role.
[0033] Secondly, the lower connecting block 32 and the limiting block 35 can also telescope and slide in the inner cavity of the window sash 2 according to the opening and closing angle of the window sash 2, so as not to affect the opening and closing angle of the window sash 2.
[0034] The steel wire rope 31 can withstand greater tension through the lower connecting block 32, the upper connecting block 36 and the small connecting block 33, thereby reducing the risk of the window falling.
