Description

Technical Field

[0001] The present application relates to the field of descenders, and in particular to a lightweight escape descender with lighting. Background Art

[0002] A descender is a safety device designed specifically for use in high-altitude falls. Its operating principle is to utilize the speed difference of a falling object for self-control. A descender primarily consists of a lifting ring, a housing 100, and a safety rope. During use, the lifting ring at one end of the housing 100 is hung on a structure, while one end of the safety rope is connected to the operator. However, existing descenders typically lack lighting, making it difficult to indicate the operator's position. Furthermore, in dark environments, it is difficult to observe the landing point during descent, which can easily lead to danger.

[0003] Therefore, a lightweight escape descender with lighting is needed. Utility Model Content

[0028] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] Reference Figure 1-3The lightweight escape descender with lighting comprises: a housing 100, side panels 101, a rotating drum 102, a rotating shaft 103, a friction member 104, a first gear 105, a second gear 106, an inner ring gear 107, and a lighting member 109. Two side panels 101 are provided and symmetrically fixed within the housing 100. The rotating drum 102 is rotatably arranged between the two side panels 101, and a rope is wound around the rotating drum. An opening is provided at the upper end of the housing 100, and one end of the rope passes through the opening and is fixed at a predetermined position. A flexible sponge pad 110 is fixedly connected to the side of the housing 100 close to the body, and a strap is provided on the housing 100 for fixing the housing 100 to the human body. At the same time, a lighting assembly is fixed to the bottom end of the housing 100. When in use, the housing 100 is fixed to the body with the strap, and one end of the rope is fixed at a predetermined position. The lighting member 109 can be configured as a light to illuminate the landing position.

[0030] The rotating cylinder 102 includes two annular plate portions 111 and a cylindrical portion 112 for connecting the two annular plate portions 111. The annular plate portions 111 are fixed at both ends of the cylindrical portion 112 and have flanges formed on both ends to limit the position of the rope. Support plates 113 are fixedly connected to both ends of the cylindrical portion 112, and the support plates 113 are fixed to the inner side of the cylindrical portion 112. The rotating shaft 103 rotates coaxially within the rotating cylinder 102, and its two ends are rotatably mounted on the support plates 113. The support plates 113 support the rotating shaft 103. In one embodiment, one end of the rotating shaft 103 passes through the support plate 113 and is fixedly connected to the first gear 105. At the same time, a second gear 106 is rotatably connected to one of the side plates 101. In one embodiment, three second gears 106 are circumferentially distributed around the axis of the rotating shaft 103, and all three second gears 106 are meshed with the first gear 105. At the same time, an inner ring gear 107 is fixedly connected to the inner wall of one end of the rotating drum 102, and the inner ring gear 107 meshes with the second gear 106. When unwinding, the rotating drum 102 rotates, and the inner ring gear 107 drives the second gear 106 to rotate, which in turn drives the first gear 105 to rotate through the second gear 106, and then drives the rotating shaft 103 to rotate.

[0031] The friction member 104 includes a fixed block 116 fixedly connected to the rotating shaft 103 and positioned between two support plates 113. A guide post 117 is fixedly connected to the fixed block 116. The guide post 117 passes through a friction block 118 and is slidably connected to the friction block 118. A spring 120 is sleeved on the guide post 117, with its ends respectively abutting against the friction block 118 and the fixed block 116. An annular groove 119 is defined on the inner wall of the cylindrical portion 112, into which the friction block 118 is inserted.

[0032] In one embodiment, three guide posts 117 are provided circumferentially. Friction blocks 118 are embedded in annular grooves 119 under the action of springs 120, and friction blocks 118 abut and rub against the inner wall of annular grooves 119. When rotating drum 102 rotates, rotating shaft 103 rotates in the opposite direction. Rotating shaft 103 rotates, driving friction blocks 118 to move. Under the action of springs 120 and centrifugal force, friction blocks 118 abut against the inner wall of annular grooves 119, thereby reducing speed.

[0033] A limiting roller 121 is fixedly connected between the two side plates 101 and is circumferentially arranged outside the annular plate portion 111. The limiting roller 121 limits the position of the rope to prevent the rope from escaping from the cylindrical portion 112.

[0034] A guide frame 122 is fixed in the housing 100 at the lower side of the opening. Two first guide rollers 108 are rotatably connected to the guide frame 122 . Two second guide rollers 115 located at the lower side of the guide frame 122 are rotatably connected between the two side plates 101 .

[0035] In one embodiment, the horizontal projections of the axis of the first guide roller 108 and the axis of the second guide roller 115 are perpendicular to each other. The first guide roller 108 and the second guide roller 115 clamp and guide the rope to ensure the direction of the rope unwinding.

[0036] The opening is fixedly connected with a cover 114, and a through hole for the rope to pass through is provided on the cover 114. A flexible sponge pad 110 is fixedly connected to the side of the housing 100 close to the body.
