Abstract
Description
Technical Field
[0001] The utility model relates to the field of decoration, and more specifically, to a door and window anti-falling device. Background Art
[0002] As people's living standards improve, the scope of indoor decoration is gradually expanding, including the decoration of doors and windows. Doors and windows will become loose due to years of use. In strong winds, doors and windows will detach, causing high-altitude falls, and even serious casualties. For this reason, anti-fall ropes are installed between doors and windows and window frames to prevent them from falling.
[0003] Most of the existing anti-fall chains fix the doors and windows by fixing anti-fall buckles on the doors and windows and installing blocks on the rope body. The blocks cannot pass through the buckles, so the doors and windows are fixed. However, this structure has the following disadvantages: 1. The buckles, doors and windows, and door locks are usually fixed with only three screws, which may become loose after long-term use; 2. When the doors and windows fall off, a large pulling force is generated, and the buckles will bend between the buckles and the blocks, causing damage to the equipment, which will still cause the doors and windows to fall. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a door and window anti-falling device, which can enhance the strength of the mounting frame itself and still maintain the stability of the mounting frame itself at the moment the door and window fall off, thereby improving safety.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door and window anti-falling device, comprising a mounting frame, a safety rope and a clamping block, wherein the clamping block is fixedly connected to the safety rope, through holes for the safety rope to pass through are arranged at both upper and lower ends of the mounting frame, the caliber of the clamping block is larger than the caliber of the through hole, a first partition plate and a second partition plate are arranged on one side of the mounting frame, the first partition plate and the second partition plate divide the mounting frame into a first reinforcement chamber, a movable chamber and a second reinforcement chamber, and the safety rope passes through the through hole and the movable chamber in sequence;
[0006] Reinforcement components are disposed in both the first reinforcement cavity and the second reinforcement cavity.
[0007] In summary, the utility model has the following beneficial effects: the inner cavity of the mounting frame is divided into independent chambers by the first partition plate and the second partition plate, so that the movement of the safety rope in the moving cavity is not interfered by the accessories on both sides, thereby ensuring the smooth movement of the safety rope.
[0008] By arranging reinforcement components in the first reinforcement cavity and the second reinforcement cavity, the strength of both sides of the movable cavity is enhanced, and at the same time the overall weight of the mounting frame is reduced. This can not only enhance the strength of the mounting frame itself, but also maintain the stability of the mounting frame itself at the moment when the door or window falls off, thereby improving safety.

It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0014] Reference Figures 1 to 3 As shown, in order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door and window anti-falling device, comprising a mounting frame 1, a safety rope 2 and a clamping block 3, the clamping block 3 is fixedly connected to the safety rope 2, the upper and lower ends of the mounting frame 1 are provided with through holes 11 for the safety rope 2 to pass through, the caliber of the clamping block 3 is larger than the caliber of the through hole 11, a first partition plate 12 and a second partition plate 13 are provided on one side of the mounting frame 1, the first partition plate 12 and the second partition plate 13 divide the mounting frame 1 into a first reinforcement chamber 14, a movable chamber 15, and a second reinforcement chamber 16, the safety rope 2 passes through the through hole 11 and the movable chamber 15 in sequence;
[0015] A reinforcement component 4 is disposed in each of the first reinforcement cavity 14 and the second reinforcement cavity 16 .
[0016] The design of the utility model utilizes the first partition plate 12 and the second partition plate 13 to separate the inner cavity of the mounting frame 1 into independent chambers, so that the movement of the safety rope 2 in the moving cavity 15 is not interfered by the accessories on both sides, thereby ensuring the smooth movement of the safety rope 2.
[0017] By arranging the reinforcing assembly 4 in the first reinforcing cavity 14 and the second reinforcing cavity 16, the strength of both sides of the movable cavity 15 is enhanced, and the overall weight of the mounting frame 1 is reduced. This can not only enhance the strength of the mounting frame 1 itself, but also maintain the stability of the mounting frame 1 itself at the moment when the door or window falls off, thereby improving safety.
[0018] The reinforcing assembly 4 includes a first reinforcing rod 41 and a second reinforcing rod 42 , and the first reinforcing rod 41 and the second reinforcing rod 42 are arranged in a staggered manner.
[0019] The first strengthening cavity 14 and the second strengthening cavity 16 are both arranged in a rectangular structure, and the first strengthening rod 41 and the second strengthening rod 42 are respectively connected to the diagonal parts of the cavity.
[0020] like Figure 2 As shown, the design of the first reinforcing rod 41 and the second reinforcing rod 42 can connect the diagonal vertices of the first reinforcing cavity 14 and the second reinforcing cavity 16 (they can be staggered as one, or the first reinforcing rod 41 and the second reinforcing rod 42 can be relatively misaligned by adjusting the angle). The design of this structure can effectively enhance the strength of the mounting frame 1 and avoid the overall weight of the mounting frame 1 being too high.
[0021] The mounting frame 1 is provided with a connecting hole 17 connected to the first reinforcement cavity 14 and the second reinforcement cavity 16 , and the connecting hole 17 is used for threading a positioning bolt.
[0022] There are four groups of connection holes 17. Figure 2 As shown, four groups of connection holes 17 are respectively arranged on the left and right sides of the moving cavity, and are located on the upper and lower sides of the intersection of the first strengthening rod 41 and the second strengthening rod 42.
[0023] The first reinforcing rod 41 and the second reinforcing rod 42 are provided with escape grooves 43 for escaping the positioning bolts.
[0024] The design of this structure is that when the positioning bolt is screwed onto the mounting frame 1, it passes through the connecting hole 17 and the avoidance groove 43 to connect with the door, window and door frame to form a fixation, which can not only ensure the smooth passage of the positioning bolt, but also enable the positioning bolt to conflict with the first reinforcing rod 41 and the second reinforcing rod 42, thereby enhancing its stability.
[0025] A buffer assembly 5 is arranged in the movable cavity 15 , and a linkage block 21 is arranged on the safety rope 2 . The linkage block 21 is located in the movable cavity 15 .
[0026] The buffer assembly 5 includes two groups of buffer blocks 51 and buffer springs 52 , and a buffer gap 53 is left between the two groups of buffer blocks 51 .
[0027] like Figure 3 As shown, the distance from the linkage block 21 to the lower through hole 11 is equidistant from the clamping block 3 to the upper through hole 11 .
[0028] When the door or window falls off, the linkage block 21 is pulled down quickly by the installation rope. At this time, the linkage block 21 passes through the buffer gap and gradually abuts against the buffer block 51, so that the buffer block 51 compresses the buffer spring 52, so that the kinetic energy is released, until the linkage block 21 abuts against the bottom and the clamping block 3 abuts against the top, which has a buffering effect during the descent.
[0029] like Figure 3 As shown, the first partition plate 12 and the second partition plate 13 are provided with chambers for installing the buffer spring 52 and also for the buffer block 51 to slide.
[0030] The buffer block 51 is arranged in a right triangle or right trapezoidal structure. Figure 3 The right-angle trapezoid is shown, so that the buffer gap gradually increases in the downward direction. The design of this structure can not only ensure that the two sides of the buffer gap are equidistant, but also strengthen the strength of the moving cavity through the buffer block.
[0031] Mounting plates 6 are provided at both upper and lower ends of the mounting frame 1, and positioning holes 61 are provided on the mounting plates 6. The design of the positioning holes 61 is an optional solution, which can be reinforced twice to ensure the stability of the equipment.
[0032] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
