Referring to fig. 1 in conjunction with fig. 2 and fig. 3, the applicant briefly describes the working principle of the slow descent escape deceleration device: when a person trapped in a high building has an accident and needs to use the slow-descent escape deceleration device for emergency escape, firstly, hooks are placed in the mounting panel hook holes 313 and the positioning panel hook holes 323 on the mounting panel 31 and the positioning panel 32, the trapped person can connect the whole deceleration device with a wall or other fixing parts through the hooks, a safety belt is arranged on a slow-descent rope to bind a human body and suspend the trapped person to descend, the slow-descent rope is drawn when the human body descends slowly, the slow-descent rope penetrates through the slow-descent rope guide grooves 41 of the rope winding disc 4 and drives the rope winding disc 4 to rotate under the guidance of the four pin shafts 336, the rope winding disc 4 further drives the gear transmission component 6 to rotate, the transmission shaft 61 starts to rotate under the transmission of the inside of the gear transmission component 6, the brake disc 62 is further driven to rotate, and in the rotation process of the brake disc 62, the constant friction and impact of movable bulb 71 and brake disc 62 on the movable friction assembly 7, when the speed of stranded escape personnel descent speed is too fast and the rope slowly descends, the rotational speed of brake disc 62 will be correspondingly fast, the contact frequency of a plurality of brake disc friction holes 621 on the circumferential surface and movable bulb 71 is naturally accelerated, the frictional resistance between brake disc 62 and the movable friction assembly 7 will become great, thereby play the deceleration effect to brake disc 6, brake disc 6 further applies the reverse acting force on transmission shaft 61 and gear drive assembly 6, make rope reel 4 and the rope slowly descend slow down the slew velocity, thereby slow down stranded escape personnel's descent speed and reach the purpose of safe and stable escape. Further, when the descending speed of the trapped evacuee is reduced, the rotating speed of the brake disc 62 is also reduced, the contact frequency between the movable ball 71 on the movable friction component 7 and the brake disc 62 is also reduced, so that the friction resistance between the movable ball 71 and the brake disc 62 is also reduced, and the rope winding disc 4 is accelerated to rotate again, so as to perform reciprocating circulation until the trapped evacuee safely falls to the ground.

When a user or a manufacturer installs the safety pin in the shell component 1, the main body connecting column 1 is installed in the connecting column accommodating through hole 332 of the connecting housing 33, the assembling rivet 2 is mutually assembled with the corresponding hole through the process of stamping and riveting and is installed together with the main body connecting column 1, when the user or the manufacturer needs to integrally assemble and disassemble the shell component 1, the head of the outer side of the assembling rivet 2 is larger, the near middle part of the main body connecting column 1 is inwards concavely provided with an information platform 11, and the main body connecting column 1 is easy to break through the stamping and semi-shearing process, after the disassembly of a fastener is realized, relevant operators can realize the integral breaking of the main body connecting column 1 by dragging the installing panel 31 and the positioning panel 32 or through external force impact, and the disassembly of the shell component 3 is realized; through the safety pin that sets up this embodiment and provide in slow descending speed reduction equipment of fleing, the basic information of the buyer corresponding with the producer backstage is supporting to be equipped with on the main part spliced pole 1 of safety pin, after placing for a long time and not using and reach the guarantee period of producer regulation after purchasing, the producer contacts the purchase individual and requests to purchase the individual and send back the producer to the life saving device that its hand was not used for a long time to maintain according to relevant information, the producer can decompose shell subassembly 3 and open and maintain the maintenance to connecting housing 33 internal component after, send back to the purchase individual again, reach the purpose of safe handling. In addition, after the related personnel in the accident use the slow-descent escape deceleration equipment, the slow-descent escape deceleration equipment can be sent back to a manufacturer for corresponding maintenance operation, and then the slow-descent escape deceleration equipment is sent back to ensure subsequent safe use; if the shell component 1 of the slow-descent escape deceleration device is disassembled because a purchaser or some irrelevant persons, and the safety pin in the embodiment belongs to a disposable assembly product, the main body connecting column 1 of the safety pin is disconnected when the shell component 3 is disassembled, after the slow-descent escape deceleration device with the condition is sent to a relevant manufacturer, the safety pin is disconnected because the irrelevant persons disassemble the safety pin at will, the condition is not in the guarantee range of the manufacturer, the manufacturer can carry out corresponding maintenance operation, legal civil rights and interests of the manufacturer can be ensured not to be damaged, and the structure of the safety pin can ensure that the slow-descent escape deceleration device cannot be opened easily after the whole installation is finished, so that the irrelevant persons can not clean and clean internal components at will conveniently or favorably, Lubrication or disassembly operation, the purpose that the industry mandatory safety standard cannot be damaged is achieved, the overall safety guarantee of the slow descent escape speed reducing device is realized, and the final guarantee of safety lifesaving is completed.

In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
