Description

Technical Field

[0001] The invention belongs to the technical field of safety protection and emergency escape, and particularly relates to a one-button start escape descender. Background Art

[0002] A general descender is composed of a hook (or ring), a sling, a rope and a speed control. It is a safety rescue device that allows people to slowly descend along a rope (belt). It can be installed on a building window, balcony or flat roof with a special installation device, or it can be installed on a high-rise fire truck to rescue victims in a high-rise building fire scene; it is suitable for high-rise escape. When working, the planetary gear reduction mechanism in the main engine is driven by the descending rope to produce friction with the friction block in the friction wheel hub to ensure that the user safely descends to the ground.

[0003] However, in case of emergency, how to quickly put on the belt, or how to start the slow-descent device with one button in an emergency and escape in time, the existing slow-descent devices do not have this function, especially the slow-descent devices used for escaping from high-rise buildings, most of which are large in size, complex in structure, high in production cost, and poor in slow-descent effect. The elderly and children cannot react in time and cannot accurately open the escape device. Summary of the invention

[0004] In order to overcome the defects of the prior art, a one-button start escape slow descender with simple operation and convenient use is designed.

[0005] The present invention provides a one-button start escape descent control device, comprising a rope device, a safety belt and an arm fixer, wherein the rope device is welded to the arm fixer and is inserted and connected with the safety belt through an insertion opening on the side of a rope drum; the rope device comprises a one-button launcher, a rope drum, a descent control rope wound around the outside of the rope drum and a hook inserted in the one-button launcher, wherein one end of the descent control rope is tied to the rope drum, and the other end is tied to the hook; the one-button launcher comprises a launch tube and a chamber welded to the launch tube through a connecting pipe, a start button is installed at one end of the launch tube through a locking nut, and a hook rack with a hook inserted at the other end, and a compressed air bottle is installed in the chamber.

[0006] Furthermore, the hook includes a scimitar-shaped hook and a columnar hook frame, and the hook and the hook frame are welded to each other.

[0007] Furthermore, a rope hole for inserting a slow-descent rope is provided at one end of the hook frame close to the hook teeth.

[0008] Furthermore, the start button and the launch tube are welded integrally, and a spring is sleeved between the start button and the launch tube.

[0009] Furthermore, the pressing cylinder is a hollow cylindrical cylinder, and a pore matching the inner diameter of the connecting pipe is provided on the cylinder wall of the pressing cylinder.

[0010] Furthermore, the rope drum comprises an insertion opening for inserting the safety belt, a conical frame for winding the descent rope, and a buckle for hanging the descent rope.

[0011] Furthermore, the safety belt includes a safety seat pocket interlaced with the safety belt, a locking tongue arranged at one end of the safety belt, and a fixing pin arranged at the other end of the safety belt.

[0012] Furthermore, the arm fixer is an arm-shaped structure formed by integral welding, and a finger insertion opening is provided at one end of the fixer.

[0013] Compared with the prior art, the advantages and technical effects of the present invention are as follows: according to the structure of the toy gun and the working principle of compressed air, the energy generated when the compressed air is released is used to launch the hook column installed in the launching tube to reach the hanging position, and the hook is fixed in a specific position by using the scimitar-shaped hook teeth. After the elderly, children or rescuers put on the safety belt, they press the button according to their own position to start the descent rope with one button, so as to achieve the purpose of convenient operation and timely escape. The descent control device has a simple structure and is easy to operate, and is suitable for various emergency escape situations. BRIEF DESCRIPTION OF THE DRAWINGS
