Description

Technical Field

[0001] This application relates to the field of emergency rescue, and in particular to a protective device for rescue personnel. Background Technology

[0002] During emergency rescue operations for malfunctioning elevators, in order to protect the rescuers and prevent them from falling into the elevator shaft, rescuers typically use safety ropes to ensure their safety. The safety ropes usually require a reliable binding point. In order to quickly launch an emergency rescue, rescuers usually use protective devices to temporarily create a reliable binding point so that the emergency rescue can proceed quickly.

[0003] Existing protective devices generally include a fixed suction cup. In an emergency rescue, the fixed suction cup is attached to the wall next to the elevator door to create a temporary binding position. Then, the safety rope is tied to the fixed suction cup to complete the connection of the safety rope, so that rescuers can quickly carry out emergency rescue.

[0004] Regarding the aforementioned technologies, existing protective devices are greatly limited by the environment. For example, when the suction cup is used for adsorption and fixation, it needs to be attached to a smooth and clean wall surface to provide sufficient adsorption force. When the wall surface at the elevator door is relatively rough or damaged, the suction cup is not easy to provide strong adsorption force, making it difficult for existing protective devices to quickly create a reliable binding position. Summary of the Invention

[0005] In order to enable the protective device to quickly create a reliable binding position in various emergency rescue environments, this application provides a protective device for rescue personnel.

[0006] The rescuer protection device provided in this application adopts the following technical solution:

[0007] A rescuer protection device includes a connecting rod and two fixing mechanisms. The two fixing mechanisms are respectively disposed at both ends of the connecting rod. Each fixing mechanism includes a fixing seat and a fixing suction cup. The two fixing seats are respectively connected to both ends of the connecting rod, and the two fixing suction cups are respectively fixedly disposed on the two fixing seats. When the protection device is in use, the two fixing suction cups are adsorbed and fixed to the two side walls, and the safety rope is tied and fixed to the connecting rod.

[0008] By adopting the above technical solution, when rescuers need to quickly carry out emergency rescue, the two fixed seats are respectively positioned opposite the two walls on either side of the elevator door. Then, the two fixed suction cups are respectively attached to the walls on both sides of the elevator door to create a temporary binding position. The safety rope is then tied to the connecting rod to complete the connection of the safety rope, enabling rescuers to quickly carry out emergency rescue. The two fixed suction cups simultaneously provide suction and fixing force, allowing the protective device to quickly create a reliable binding position in various emergency rescue environments. Furthermore, the two fixed suction cups are connected by the connecting rod, further improving the safety of the protective device. This addresses the problem that existing protective devices are greatly restricted by the environment. For example, when the fixed suction cups are attached, they need to be attached to a smooth and clean wall surface to provide sufficient suction force. When the wall surface at the elevator door is relatively rough or damaged, the fixed suction cups are not easy to provide strong suction force, making it difficult for existing protective devices to quickly create a reliable binding position.

[0009] Optionally, both of the fixing seats include a first fixing part and a second fixing part, the first fixing part and the second fixing part are fixedly connected, and the first fixing part and the second fixing part are perpendicular to each other. The two ends of the connecting rod are respectively connected to the two first fixing parts, and the two first fixing parts are arranged facing each other.

[0010] Optionally, the two fixed suction cups are respectively fixedly disposed on the two second fixing parts.

[0011] Optionally, the fixing mechanism further includes an auxiliary suction cup, which is fixedly disposed on the first fixing part such that the adsorption surface of the auxiliary suction cup and the adsorption surface of the fixed suction cup are perpendicular to each other.

[0012] Optionally, the fixed suction cup includes a housing part, a suction cup part, and a pressing part. The suction cup part is disposed on one side of the housing part, and the pressing part is rotatably connected to the suction cup part and located on the other side of the housing part. The pressing part abuts against the other side of the housing part, and the pressing part rotates toward the housing part to drive the suction cup part to adsorb.

[0013] Optionally, the fixing seat has a fixing hole, and when the fixing seat and the connecting rod are connected, the connecting rod passes through the fixing hole.

[0014] Optionally, the fixing seat is threaded with at least one connecting bolt, and when the connecting rod passes through the fixing hole, the connecting bolt and the connecting rod are pressed together and fixed.

[0015] Optionally, the connecting rod includes a rod body and at least one telescopic part, the telescopic part being connected to the rod body and capable of sliding towards or away from the rod body to extend or shorten the length of the connecting rod.

[0016] Optionally, the connecting rod is threaded with at least one fixing bolt, and when the telescopic part and the rod body are in a fixed relative position, the fixing bolt is abutted and fixed to the telescopic part.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When rescuers need to quickly launch an emergency rescue, the two fixed bases are positioned opposite the walls on either side of the elevator entrance. Then, the two suction cups are attached to the walls on either side of the elevator entrance to create a temporary binding position. The safety rope is then tied to the connecting rod to complete the connection, allowing rescuers to quickly launch an emergency rescue. The two suction cups simultaneously provide suction force, enabling the protective device to quickly create a reliable binding position in various emergency rescue environments. Furthermore, the connection between the two suction cups via the connecting rod further enhances the safety of the protective device and addresses the limitations of existing protective devices that are heavily reliant on environmental conditions. Specifically, the suction cups require a smooth, clean wall surface to provide sufficient suction force. When the wall surface at the elevator entrance is rough or damaged, the suction cups cannot provide strong suction, making it difficult for existing protective devices to quickly create a reliable binding position.

[0028] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0029] This application discloses a protective device for rescue personnel. (Refer to...) Figure 1 A rescuer protection device includes a connecting rod 1 and two fixing mechanisms 2. The two fixing mechanisms 2 are respectively disposed at both ends of the connecting rod 1 and are used to fix and connect to the walls on both sides of the elevator door.

[0030] Reference Figure 2 The connecting rod 1 includes a rod body 11 and a telescopic part 12. Both the rod body 11 and the telescopic part 12 are hollow tubes. The inner diameter of the rod body 11 is equal to the outer diameter of the telescopic part 12. The telescopic part 12 passes through and slides inside the rod body 11, so that the telescopic part 12 can slide towards or away from the rod body 11, thereby lengthening or shortening the length of the connecting rod 1. The rod body 11 is threaded with a fixing bolt 111. When the telescopic part 12 and the rod body 11 are in a fixed relative position, the fixing bolt 111 abuts against the telescopic part 12, so that the telescopic rod and the rod body 11 are not easy to continue to slide relative to each other, thereby keeping the length of the connecting rod 1 stable.

[0031] Reference Figure 3 and Figure 4Both fixing mechanisms 2 include a fixing seat 21, and both fixing seats 21 include a first fixing part 211 and a second fixing part 212. The first fixing part 211 and the second fixing part 212 are fixedly connected and perpendicular to each other. The two ends of the connecting rod 1 are respectively connected to the two first fixing parts 211, and the two first fixing parts 211 are arranged facing each other. Each of the two first fixing parts 211 has a fixing hole 2111 on one side facing each other. When the fixing seat 21 and the connecting rod 1 are connected, the connecting rod 1 passes through the fixing hole 2111. The first fixing part 211 is threaded with a connecting... When the connecting rod 1 is inserted into the fixing hole 2111, the connecting bolt 2112 abuts against the outer circumferential surface of the connecting rod 1, thereby achieving a fixed connection between the first fixing part 211 and the connecting rod 1. At the same time, when the first fixing part 211 and the connecting rod 1 need to be disengaged, the connecting bolt 2112 is turned, thereby causing the connecting bolt 2112 to disengage from the outer circumferential surface of the connecting rod 1, so that the connecting rod 1 can be disengaged from the fixing hole 2111, thereby achieving quick disassembly of the first fixing part 211 and the connecting rod 1. In the embodiments of this application, the connecting bolt 2112 are all easy-tightening bolts.

[0032] Reference Figure 5 and Figure 6 Both fixing mechanisms 2 also include a fixing suction cup 22, which is respectively disposed on two second fixing parts 212. The fixing suction cup 22 includes a housing part 221, a suction cup part 222, a pressing part 223, and a handle part 224. The housing part 221 is fixedly connected to the second fixing part 212. The suction cup part 222 is disposed on one side of the housing part 221. The pressing part 223 is rotatably connected to the suction cup part 222 and is located on the other side of the housing part 221. The pressing part 223 abuts against the other side of the housing part 221, and the pressing part 223 presses and fixes the second fixing part 212 against the housing part 221, so that the housing part 212 is fixed to the housing part 221. 21 is fixedly connected to the second fixing part 212, and the handle part 224 is fixedly disposed on the housing part 221. When the fixed suction cup 22 is used for adsorption and fixation, the suction cup part 222 and the surface to be adsorbed are brought into contact, and the pressing part 223 rotates toward the housing part 221, thereby causing the suction cup part 222 to contract toward the housing part 221, thereby increasing the volume of the enclosed space between the suction cup part 222 and the surface to be adsorbed, thereby making the air pressure between the suction cup part 222 and the surface to be adsorbed lower than the external air pressure, thereby making the fixed suction cup 22 adsorb and fix to the surface to be adsorbed. In this embodiment, the suction cup part 222 is elastic.

[0033] Reference Figure 3Both fixing mechanisms 2 also include auxiliary suction cups 23. The two auxiliary suction cups 23 are respectively fixedly installed on the side of the two first fixing seats 21 that are far apart from each other, so that the adsorption surface of the auxiliary suction cup 23 and the adsorption surface of the fixed suction cup 22 are perpendicular to each other. This makes the direction of the adsorption fixing force provided by the auxiliary suction cup 23 and the fixed suction cup 22 perpendicular to each other, thus making the direction of the fixing force provided by the fixing mechanism 2 more diverse, thereby further stabilizing the fixed connection between the fixing mechanism 2 and the wall at the elevator door.

[0034] Reference Figure 7 The implementation principle of a rescuer protection device according to an embodiment of this application is as follows: When rescuers need to quickly carry out emergency rescue, the two ends of the connecting rod 1 are respectively inserted into the two fixing holes 2111, and the connecting bolts 2112 are tightened and fixed to the outer circumference of the connecting rod 1. Then, the two fixing suction cups 22 are respectively abutted against the two first side walls 201 of the elevator door 20, directly causing the telescopic part 12 to move away from the main body, thereby extending the length of the connecting rod 1 until the two auxiliary suction cups 23 are respectively attached and fixed to the two second side walls 202 of the elevator door 20. The two pressing parts 223 are directly rotated, so that the two fixing suction cups 22 are respectively attached and fixed to the two first side walls 201 of the elevator door 20, thereby completing the creation of a temporary binding position. Then, the safety rope is tied to the connecting rod 1. The connection of the safety rope allows rescuers to quickly launch emergency rescue operations. The two fixed suction cups 22 simultaneously provide suction and fixation force, enabling the protection device 10 to quickly create a reliable binding position in various emergency rescue environments. Furthermore, the two fixed suction cups 22 are connected by the connecting rod 1, which further improves the safety of the protection device 10 and addresses the problem that the existing protection device 10 is greatly restricted by the environment. Specifically, when the fixed suction cups 22 are used for suction and fixation, they need to be attached to a smooth and clean wall surface to provide sufficient suction force. When the wall surface at the elevator entrance 20 is relatively rough or damaged, the fixed suction cups 22 are not easy to provide strong suction force, making it difficult for the existing protection device 10 to quickly create a reliable binding position.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
