Abstract
The invention relates to a safety belt buckle of a descent control device.A zipper head mounting shaft is arranged at two ends of a locking buckle main body, and a zipper head is arranged on the zipper head mounting shaft in a sliding manner; a locking block shaft is arranged on one side, away from the zipper head, of the two side surfaces of the locking buckle main body, and a safety belt locking block is rotatably arranged on the locking block shaft; magnets are arranged on two side surfaces of the safety belt buckle main body, the safety belt buckle is pulled to the bottom during escape, the tension of the safety belt is greater than that of the magnet attraction force, the locking block rotates to lock the safety belt, automatic locking of the safety belt is achieved, and the tension of the safety belt and the locking of the locking block are simultaneously enhanced as the escape personnel is far away from the ground; when the first escape personnel arrive ground through reciprocating type descent control device, pull the hasp to the safety belt bottom, use through the cooperation of drawing zipper head and setting the zip fastener in the safety belt both sides, two strands of safety belts become an organic whole, and this safety belt rises when follow-up escape personnel descend, can prevent to catch on window or the outer quick-witted support of air conditioner, has guaranteed the reciprocating use of the high-efficient safety of descent control device under the emergency.
Description
Technical Field
The invention relates to the technical field of high-altitude fire-fighting and life-saving instruments, in particular to a descent control device safety belt buckle with automatic locking and anti-reverse hanging functions.
Background
The slow lowering device consists of a hook (or a hanging ring), a hanging strip, a rope, a speed control (damper) and the like, and is a safety rescue device which can make people slowly descend along (along) the rope (belt). The device is installed at the window of a building, a balcony, a flat top of the building and the like by using a special installation device, and can also be installed on a high-rise fire truck or a rescue helicopter to rescue the person in distress on the fire scene of a high-rise building. When the speed controller works, the damping part in the speed controller is driven by the slow descending rope to generate speed reduction, so that a user is ensured to safely and slowly descend to the ground. The slow descending rope generally adopts an aviation high-grade steel wire rope, and two ends of the slow descending rope are respectively provided with a set of safety belt. The existing safety belt lock catch of the descent control device does not have an automatic locking function and an anti-reverse hanging function, and escape personnel cannot rapidly and correctly lock the safety belt under the condition of confusion, so that life safety is threatened by prolonging the escape time, and a window, an air conditioner outer machine support and the like are easily hooked when the safety belt ascends, so that the reciprocating use of the descent control device is influenced.
Disclosure of Invention
The invention aims to provide a descent control device safety belt buckle with automatic locking and anti-reverse hanging functions, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a descent control device safety belt buckle with automatic locking and anti-reverse hanging functions comprises a locking buckle main body, wherein two ends of the locking buckle main body are provided with zipper head mounting shafts, zipper heads are arranged on the zipper head mounting shafts and can be arranged on the zipper head mounting shafts in a sliding mode;
a locking block shaft is arranged on one side, away from the zipper head, of the two side surfaces of the locking buckle main body, and a locking block is rotatably arranged on the locking block shaft;
the locking buckle is characterized in that magnet mounting holes are formed in two side faces of the locking block and are mounted on the locking buckle main body, magnets are arranged in the magnet mounting holes, and the magnets and the locking block are matched with each other.
Preferably, four sets of magnet mounting holes and magnets are arranged in bilateral symmetry.
Preferably, the locking buckle main body is integrally cast.
Preferably, the locking buckle main body is made of aluminum alloy.
Has the advantages that: compared with the prior art, the invention has the advantages that the automatic locking work of the safety belt buckle is realized by the mutual matching of the tension generated by the safety belt when the safety belt buckle is pulled to the bottom and the locking block; through the cooperation of drawing zipper head and setting at the zip fastener of safety belt both sides and using, after first flee personnel reachd ground, follow-up flee personnel descend with other end safety belt, and this safety belt rises, pulls the safety belt bottom to the hasp like this, and two strands of safety belts become an organic whole, prevent to catch on the outer quick-witted support of window or air conditioner, have guaranteed the high-efficient safe reciprocal use of ware that slowly falls under the emergency.

Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.
Examples
Referring to the attached drawings in the specification, in the embodiment of the invention, a descent control device safety belt buckle with automatic locking and anti-reverse hanging functions comprises a locking buckle main body 1, wherein two ends of the locking buckle main body 1 are provided with zipper head mounting shafts 2, each zipper head mounting shaft 2 is provided with a zipper head 3, and each zipper head 3 is slidably arranged on the corresponding zipper head mounting shaft 2; the zipper head 3 is matched with the zippers arranged on the two side edges of the safety belt;
a locking block shaft 4 is arranged on one side, away from the zipper head 3, of the two side surfaces of the locking buckle main body 1, and a locking block 7 is rotatably arranged on the locking block shaft 4;
the locking buckle is characterized in that magnet mounting holes 5 are formed in two side faces of the locking block 7 and mounted on the locking buckle main body 1, magnets 6 are arranged in the magnet mounting holes 5, and the magnets 6 are matched with the locking block 7.
