Description

Technical Field

[0001] This utility model relates to the field of high-altitude rescue equipment technology, specifically an emergency high-altitude rescue device. Background Technology

[0002] Chinese utility model patent CN109464759A discloses a rapid rescue device for high-altitude buildings, including an external rescue net, external support rods, external wall support rods, horizontal supports, internal upper supports, ceiling support rods, handles, control panels, operating rods, hydraulic cylinders, horizontal opening springs, net-tensioning springs, and three-degree-of-freedom joints. The external rescue net and external support rods result in a simple structure, easy disassembly and storage, and minimal space occupation, facilitating rapid deployment by rescuers. Because it can be deployed a short distance below a person contemplating suicide, it reduces secondary injury. However, in this prior art, the high-altitude building rapid rescue device utilizes two sets of external support rods opened in a V-shape with an external rescue net. However, the V-shaped external rescue net near the external wall is narrow, and the width of the net varies from front to back, resulting in poor rescue effectiveness.

[0003] Therefore, this utility model provides an emergency high-altitude rescue device to solve the above problems. Utility Model Content

[0004] This utility model provides an emergency high-altitude rescue device, which aims to solve the problems mentioned in the background art, such as the existing high-altitude building rapid rescue device using two sets of external window support rods opened in a V shape and equipped with an external rescue net, but the V-shaped external rescue net near the external wall is narrow and the width of the external rescue net is uneven, resulting in poor rescue effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency high-altitude rescue device, including a life-saving net structure installed on a windowsill;

[0006] The rescue net structure includes a placement plate set on the end face of the windowsill. Support rods are symmetrically installed on the end face of the placement plate. Rescue net pockets are installed on the corresponding side walls of the two sets of support rods. An exterior wall panel is installed on the back of the placement plate, and an L-shaped frame is set on the front of the placement plate. A threaded rod is installed on the L-shaped frame through threaded holes. A pressure plate is rotatably installed on the end of the threaded rod near the exterior wall panel. A lifting rod is installed on the side wall of the support rod away from the rescue net pocket. By setting up the rescue net structure with a rescue net pocket between the two sets of support rods, the front and back width of the rescue net pocket is consistent. This avoids the problem in existing high-altitude building rapid rescue devices where the V-shaped rescue net near the exterior wall is narrow and the front and back widths are inconsistent. This results in a larger coverage area for the rescue net pocket and better rescue effectiveness.

[0007] Preferably, an installation plate is installed on the side wall of the support rod away from the life-saving net, a fixed shaft is installed on the side wall of the installation plate, a connecting sleeve rotatably connected to the fixed shaft and a limiting cylinder are installed on the lifting rod, and a locking structure is installed on the end face of the support rod corresponding to the limiting cylinder;

[0008] The locking structure includes a mounting cylinder installed on the end face of the support rod. A plug rod is slidably mounted on the mounting cylinder through a connecting hole. A connecting ring is installed on the outer wall of the plug rod, and a spring is installed on the connecting ring and on the outer wall of the plug rod.

[0009] Preferably, the lifting rod includes a supporting housing mounted on the side wall of the connecting sleeve, a lead screw rotatably mounted on the supporting housing via a bearing, an inner rod being threaded onto the lead screw, and a throttle handle disposed at the lower end of the lead screw.

[0010] Preferably, a shaft retainer is installed at the bottom of the support housing and outside the lead screw, the inner cavity of the support housing is slidably connected to the inner rod, a limit groove is formed on the side wall of the inner cavity of the support housing, and a stop block is installed on the side wall of the inner rod that is slidably connected to the limit groove.

[0011] Preferably, a knob is installed at the other end of the threaded rod, the pressure plate is slidably connected to the inner end face of the L-shaped frame, a reinforcing rod is installed on the side wall of the outer wall panel, and the other end of the reinforcing rod is connected to the bottom of the support rod.

[0012] Preferably, the inner wall of the mounting cylinder is rotatably connected to the outer wall of the connecting ring, and the inner cavity of the mounting cylinder is connected to the other end of the spring.

[0013] Beneficial effects: By setting up a rescue net structure and using a combination of placement board, support rods, rescue net bag, and pressure plate, a rescue net bag is placed between two sets of support rods, ensuring that the front and back width of the rescue net bag is consistent. This avoids the problem in existing high-altitude building rapid rescue devices that use two sets of external support rods to open in a V-shape and set up an external rescue net, where the V-shaped external rescue net near the external wall is narrow and the front and back width of the external rescue net is inconsistent. This results in a larger coverage area for the rescue net bag and a better rescue effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] This embodiment provides an emergency high-altitude rescue device, such as... Figure 1-6 As shown, the high-altitude rescue device includes a life-saving net structure 2 installed on the windowsill 1;

[0024] The life-saving net structure 2 includes a placement plate 21 set on the end face of the windowsill 1. Support rods 22 are symmetrically installed on the end face of the placement plate 21. Life-saving net bags 23 are installed on the corresponding side walls of the two sets of support rods 22. An outer wall plate 24 is installed on the back of the placement plate 21 and an L-shaped frame 25 is set on the front of the placement plate 21. A threaded rod 26 is installed on the L-shaped frame 25 through a threaded hole. A pressure plate 27 is rotatably installed on the end of the threaded rod 26 near the outer wall plate 24. A lifting rod 28 is installed on the side wall of the support rod 22 away from the life-saving net bag 23.

[0025] In use, rescuers place the placement board 21 on the end face of the windowsill 1. The placement board 21 drives two sets of support rods 22, extending the life-saving net 23 outside the window. Simultaneously, the placement board 21, along with two sets of outer wall panels 24, adheres to the outer wall. The knob 261 drives the threaded rod 26 to rotate clockwise, which in turn drives the pressure plate 27 to move towards the inner wall of the windowsill 1 until the pressure plate 27 presses against the inner wall, thus securing the placement board 21 to the windowsill 1 with the outer wall panels 24. Then, the handle 284 drives the lead screw 282 to rotate clockwise, which in turn drives the inner rod 283 to move upward, causing the upper end of the inner rod 283 to press against the ceiling. This prevents the person attempting suicide from entering the room. When a person falls onto the rescue net 23, the indoor end of the support rod 22 is held against the ceiling by the lifting rod 28, preventing it from tilting upwards. This makes the installation of the rescue net structure 2 more secure. The rescue net 23 is positioned between the two sets of support rods 22, ensuring that the front and back widths of the rescue net 23 are consistent. The rescue net 23 has a large coverage area, which can better catch the person attempting suicide. This avoids the problem in existing high-altitude building rapid rescue devices where two sets of external support rods are opened in a V-shape and an external rescue net is installed. However, the V-shaped external rescue net near the external wall is narrow, and the front and back widths of the external rescue net are inconsistent. This improves the rescue effect.

[0026] In this embodiment, the lifting rod 28 includes a support housing 281 installed on the side wall of the connecting sleeve 6. A lead screw 282 is rotatably mounted on the support housing 281 via a bearing. An inner rod 283 is threaded onto the lead screw 282, and a handle 284 is provided at the lower end of the lead screw 282. A shaft retainer 285 is installed at the bottom of the support housing 281 and outside the lead screw 282. The inner cavity of the support housing 281 is slidably connected to the inner rod 283. A limit groove 2811 is formed on the side wall of the inner cavity of the support housing 281. A stop block 2831 that is slidably connected to the limit groove 2811 is installed on the side wall of the inner rod 283.

[0027] Among them, by setting the shaft retainer 285, after the lead screw 282 drives the inner rod 283 to rise to a certain height, the shaft retainer 285 locks the lower outer wall of the lead screw 282 to prevent the lead screw 282 from sliding down naturally under the action of gravity; by setting the limiting groove 2811 and the stop block 2831, the rising height of the inner rod 283 is limited to prevent the inner rod 283 from disengaging from the threaded connection of the lead screw 282, thus ensuring the normal operation of the life-saving net structure 2;

[0028] In this embodiment, a knob 261 is installed at the other end of the threaded rod 26, the pressure plate 27 is slidably connected to the inner cavity end face of the L-shaped frame 25, and a reinforcing rod 3 is installed on the side wall of the outer wall plate 24. The other end of the reinforcing rod 3 is connected to the bottom of the support rod 22.

[0029] Among them, the reinforcing rod 3 provides support for the support rod 22, which can increase the load-bearing capacity of the support rod 22 and improve the safety of the rescue net 23.

[0030] Example 2

[0031] Unlike Embodiment 1, the side wall of the support rod 22 away from the life-saving net 23 is equipped with an installation plate 4, the side wall of the installation plate 4 is equipped with a fixed shaft 5, the lifting rod 28 is equipped with a connecting sleeve 6 that is rotatably connected to the fixed shaft 5 and a limiting cylinder 7 set on the lifting rod 28, and a locking structure 8 is installed on the end face of the support rod 22 corresponding to the limiting cylinder 7.

[0032] The locking structure 8 includes a mounting cylinder 81 installed on the end face of the support rod 22. The mounting cylinder 81 is slidably mounted with a plug rod 82 through a connecting hole. A connecting ring 83 is installed on the outer wall of the plug rod 82. A spring 84 is installed on the connecting ring 83 and located on the outer wall of the plug rod 82.

[0033] When in use, after the high-altitude rescue device has completed the rescue, pull the insertion rod 82 away from the installation cylinder 81. The insertion rod 82 moves out of the limiting cylinder 7, so that the support shell 281 loses its position control. The support shell 281 can be rotated and placed parallel to the support rod 22, realizing the folding effect of the lifting rod 28. This can reduce the space occupied by the high-altitude rescue device, thereby facilitating the movement and transportation of the high-altitude rescue device and improving the flexibility of the high-altitude rescue device.

[0034] In this embodiment, the inner wall of the mounting cylinder 81 is rotatably connected to the outer wall of the connecting ring 83, and the inner cavity of the mounting cylinder 81 is connected to the other end of the spring 84.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the scope of protection of this utility model.
