Abstract
The invention relates to a speed-adjustable descending device with a single handle. The device comprises the speed adjusting handle and a main body bracket, wherein the speed adjusting handle is distributed at the left side of the main body bracket, and the middle of the speed adjusting handle is in rotary connection with the main body bracket through a pin B. According to the device, the handle can be outwards pulled to achieve the purpose of adjusting the speed; the operation is convenient; the speed adjusting range can be determined according to the handle pulling range, and stepless speed adjustment can be achieved. The device is simple in structure, low in cost, convenient to carry on, and suitable for popularization and application, and can be applied to working at heights, rapid descending during mountaineering, escaping at high altitudes, etc.
Description
Technical field
The present invention relates to a kind of monolever adjustable speed drop device, belong to high level quick falling device.
Background technology
Prompt drop device obtains application in increasing occasion, as work high above the ground, mountain-climbing prompt drop, height rescue etc.In prompt drop, what the most often adopt is rope prompt drop.Rope prompt drop utilizes rope that people is dropped to lower from eminence.How to utilize rope by people's safety, lower under stable and become the important content of research mountain-climbing drop device.
Existing prompt drop device utilizes a kind of drop device of rope eyelet mostly, regulates friction rope and drop device by adjustment rope through the number in the hole of drop device.Also have a kind of drop device utilizing mechanical friction, pull handle, utilize the draw-in groove clamping rope of handle end, play the object of reduction of speed.But this drop device can not realize autonomous ACTIVE CONTROL decrease speed, cause decrease speed very fast, have certain danger.Existing drop device is short of to some extent in auto-control speed-regulating, stability and ease-to-operate.
Summary of the invention
The object of the invention is to the defect existed for prior art, provide a kind of monolever adjustable speed drop device for decline process of climbing the mountain.There is good stability, easy and simple to handle, can the advantage such as continuous speed adjustment.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of monolever adjustable speed drop device, comprises speed adjusting lever and main body rack; It is characterized in that: described speed adjusting lever is distributed on the left of main body rack, centre is rotationally connected by second pin and main body rack.
Described speed adjusting lever comprises spring support, regulating spring, friction wheel, handle and lower fixed block, described spring support upper end and handle upper end mobile link, and lower end is taken turns by pin and friction and is rotationally connected; Described regulating spring is enclosed within the middle part of spring support; Be fixedly connected with lower fixed block by screw in the middle part of described handle.
Described main body rack comprises after-poppet, rivet, upper fixed block, first pin, second pin and fore-stock, described after-poppet upper end is fixedly connected with rivet one end, middle and upper part is fixedly connected with upper fixed block by first pin, middle part is by being rotationally connected in the middle part of second pin and fore-stock, and upper end and the middle and upper part of described fore-stock have groove.
The present invention compared with prior art, has following apparent outstanding feature and remarkable technological progress:
The present invention outwards pulls the object that handle just can reach speed governing, easy to operate, and the scope of speed governing can be determined according to the amplitude pulling handle, can realize stepless speed regulation.Structure of the present invention is simple, and cost is low, conveniently carries with, and contributes to applying.Can be applicable to work high above the ground, mountain-climbing prompt drop, high altitude escape etc.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of monolever adjustable speed of the present invention drop device.
Fig. 2 is the band rope schematic diagram of a kind of monolever adjustable speed of the present invention drop device.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in further detail:
As shown in Figure 1, a kind of monolever adjustable speed drop device, comprises speed adjusting lever I and main body rack II; It is characterized in that: described speed adjusting lever I is distributed on the left of main body rack II, centre is rotationally connected by second pin 8 and main body rack II.
As shown in Figure 2, described speed adjusting lever I comprises spring support 1, regulating spring 2, friction wheel 3, handle 9 and lower fixed block 11, described spring support 1 upper end and handle 9 upper end mobile link, and lower end is taken turns 3 by pin and friction and is rotationally connected; Described regulating spring 2 is enclosed within the middle part of spring support 1; Be fixedly connected with lower fixed block 11 by screw in the middle part of described handle 9.
Described main body rack II comprises after-poppet 4, rivet 5, upper fixed block 12, first pin 6, second pin 8 and fore-stock 7, described after-poppet 4 upper end is fixedly connected with rivet 5 one end, middle and upper part is fixedly connected with upper fixed block 12 by first pin 6, middle part is by being rotationally connected in the middle part of second pin 8 and fore-stock 7, and upper end and the middle and upper part of described fore-stock 7 have groove.
The operation principle accompanying drawings of a kind of monolever adjustable speed drop device of the present invention is as follows:
First, fore-stock 7 is opened in rotation, by rope 10 around on upper fixed block 12 and lower fixed block 11, origin-location is being got back in fore-stock 7 rotation, caught on by the end hook of fore-stock 7 on the safety belt tying up to human body waist, in decline process, a hand outwards pulls speed adjusting lever I, friction wheel 3 extruding rope 10, plays the object of deceleration.Extruding degree is determined by hand pull force, and when being wrenched to a certain extent, human body stops gliding.The adjustment of drop device speed relies on hand to be wrenched the degree of speed adjusting lever.
