Description

Technical Field

[0001] This utility model relates to the field of high-altitude descent devices, specifically to a portable high-altitude descent device. Background Technology

[0002] A descent device is a high-rise escape safety device consisting of hooks (or rings), straps, ropes, and a speed control mechanism. It is primarily used for the slow descent of people from the outside of a building in emergencies such as fires. Installation must be performed by professionals and must pass mandatory national certification; it is particularly suitable for residents of buildings with 10 or more floors. When using it, the device must be secured, a safety harness must be worn, and the procedure must be followed. Obstacles must be avoided during the descent, and it should only be used when conventional escape methods are ineffective.

[0003] In existing technologies, portable descent devices mainly achieve the effect of slow descent through friction. As the descent speed increases, the resistance of centrifugal descent increases until the resistance is equal to the user's weight. However, for heavier users, the descent speed is still relatively fast, posing a safety hazard.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide a portable high-altitude descent device that can effectively solve the above-mentioned technical problems.

[0006] To achieve the purpose of this utility model, the following technical solution is adopted: a portable high-altitude descent device, comprising: a housing and an adjustable descent mechanism;

[0007] The descent mechanism includes: a rotating shaft with two rope reels mounted on it; a descent device is mounted on one end of each rope reel, and a descent disc is fixedly mounted on the other end of each rope reel; the sides of the two descent discs are in contact with each other; a rope is wound around the rope reel, the rope passes through a groove, and the rope is wound around and passes through a fixed rod.

[0008] Furthermore, a handle is fixedly installed on the housing.

[0009] Furthermore, the descent device consists of a limiting rod, a sliding block, and a fixed cylinder.

[0010] Furthermore, the fixed cylinder is fixedly installed on the inner wall of the housing, the sliding block is in contact with the inner wall of the fixed cylinder, and the sliding block is slidably installed on the limiting rod, and the limiting rod is fixedly installed on one end of the winding wheel.

[0011] Furthermore, the ropes on the two reels are wound in opposite directions.

[0012] Furthermore, the fixing rod is cylindrical.

[0013] Compared with the prior art, the present invention has the following advantages: The present invention is a portable high-altitude descent device, which changes the resistance encountered by the rope sliding on the fixed pole by adjusting the number of turns of the rope around the fixed pole, so that the device can be used by heavier users.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0020] like Figures 1 to 2 As shown, this utility model discloses a portable high-altitude descent device, comprising: a housing 1, an adjustable descent mechanism; a hanging ring 2 is fixedly installed on the housing 1, and a handle 4 is fixedly installed on the side of the housing 1 to facilitate carrying the device. The housing 1 is suspended and fixed by the hanging ring 2, and the descent mechanism makes the device suitable for heavier users, preventing them from falling too quickly when using the high-altitude descent device and preventing safety issues.

[0021] The deceleration mechanism includes: a rotating shaft 31, with both ends of the rotating shaft 31 fixedly mounted on the inner wall of the housing 1; two rope winding wheels 32 rotatably mounted on the rotating shaft 31, symmetrically distributed on the rotating shaft 31; and a deceleration component 33 mounted at the end of the rope winding wheel 32 near the inner wall of the housing 1. The deceleration component 33 consists of a limiting rod, a sliding block, and a fixed cylinder. The fixed cylinder is fixedly mounted on the inner wall of the housing 1, and the sliding block contacts the inner wall of the fixed cylinder. The sliding block is slidably mounted on the limiting rod, which is fixedly mounted on one end of the rope winding wheel 32. During the rotation of the rope winding wheel 32, the rope winding wheel 32 drives the limiting rod to rotate, which in turn drives the sliding block to rotate. The centrifugal force generated by the rotation of the sliding block causes the sliding block to decelerate. The moving block slides and contacts the inner wall of the fixed cylinder, generating frictional resistance between the fixed cylinder and the sliding block. As the rotational speed of the rope reel 32 increases, the centrifugal force increases, further increasing the frictional resistance and achieving a slow descent effect. A slow descent disc 34 is fixedly installed at the other end of the rope reel 32, with the sides of the two slow descent discs 34 in contact. A rope 35 is wound around the rope reel 32, and one end of the rope 35 is fixedly connected to the rope reel 32. The rope 35 passes through a groove 36, and two grooves 36 are symmetrically arranged at the bottom of the housing 1. The grooves 36 are aligned with the rope reel 32, and the rope 35 is wound around and passes through a fixed rod 37. Both ends of the fixed rod 37 are fixedly connected to the housing 1, while the other end of the rope 35 is connected to the safety belt.

[0022] Furthermore, the ropes 35 on the two rope reels 32 are wound in opposite directions. When the user uses the device, the user's weight causes one end of the rope 35 to descend. After the rope 35 is pulled, it drives the rope reels 32 to rotate. The two rope reels 32 rotate in opposite directions, which in turn drives the descent discs 34 to rotate, causing the two descent discs 34 to rotate in opposite directions. The two descent discs 34 also rub against each other, which reduces the initial acceleration of the user's descent when using the device, further reducing the speed during the descent and preventing the user from being injured when contacting the ground.

[0023] It should be added that the fixing rod 37 is broken into two sections, and the gap between the two sections of the fixing rod 37 is wider than the diameter of the rope 35; when using it, heavier users can increase or decrease the number of turns of the rope 35 by passing it through the gap between the two sections of the fixing rod 37.

[0024] Furthermore, the fixing rod 37 is cylindrical, and the rope 35 is preferably made of wear-resistant steel cable. After the rope 35 is wrapped around the fixing rod 37, the frictional resistance between the fixing rod 37 and the rope 35 is relatively large, which is suitable for users with larger weight. Depending on the user's weight, the device can be adapted to the user's weight by increasing or decreasing the number of wrapping turns, so that some users whose weight exceeds the normal range can escape in an emergency.

[0025] Working principle:

[0026] An additional descent structure is added to the existing braking mechanism. After the rope 35 is wrapped around the fixed rod 37, the user's weight increases the frictional resistance between the rope 35 and the fixed rod 37, reducing the time it takes for overweight users to reach a constant speed during descent, and also reducing the magnitude of the constant speed achieved by the user, thus ensuring safety. Furthermore, the number of turns of the rope 35 around the fixed rod 37 can be increased or decreased according to the user's weight and the distance between the user and the ground, making the device meet the actual requirements. The descent structure is simple and has a low cost.
