Further, speed adjusting mechanism is including locating the driving gear of pivot tip, with the reduction gear of driving gear meshing, wherein:

the rotating shaft horizontally penetrates through the protective shell through the end part of the rotating shaft, and the reduction gear is rotatably connected to the protective shell through a gear shaft;

the handle is connected in the pivot of keeping away from the reduction gear direction through its one end, just the other end of handle extends to the protective housing outside to can rotate relative to the protective housing.

Furthermore, the rotating shaft is provided with check rings at positions close to the two ends of the rotating shaft, and the pull rope is positioned between the two check rings; the rotating shaft is close to the lower end direction of the main body, and the pull rope extends along the vertical direction and penetrates out of the upper end of the main body; the handle is in the shape of an arc rod and extends backwards after penetrating out of the protective shell.

Further, the straps comprise a left strap and a right strap, which cross each other at the upper end; still be equipped with the horizontal connecting band between left side braces and the right braces, the connecting band sets gradually in the direction of height.

Furthermore, the lower ends of the left and right braces are provided with square buckles; the protective shell wraps the main body inside.

Further, the safety lock catch is of a safety lock catch structure for mountaineering.

Compared with the prior art, the invention has the advantages that:

by providing the backpack with the winding mechanism, a user can conveniently realize high-altitude or high-rise landing, the descending process is controllable, and the backpack is high in practicability and safety;

through providing a mechanism with handle to convenience of customers carries out nimble governing descending speed at the in-process that descends, and the functionality is stronger, convenient to use.

Detailed Description

The present invention is described in further detail below with reference to figures 1-3.

A high-altitude slow descent bag comprises a backpack main body, wherein the back of the main body is provided with braces 1, the outer part of the main body is provided with a protective shell 2, and the braces 1 are exposed outside the protective shell 2; a winding mechanism is arranged between the protective shell 2 and the main body, and comprises a rotating shaft 3, a pull rope 5 wound on the rotating shaft 3 and a speed regulating mechanism positioned at the end part of the rotating shaft 3; a speed regulating handle 4 is further arranged on the rotating shaft 3, and the handle 4 extends to the outside of the protective shell 2; one end of the pull rope 5 extends to the outside of the protective shell 2 and is connected with a safety lock catch 6 which can be opened and closed freely.

In-process that utilizes this device to carry out high building whereabouts utilizes safety catch 6 to connect on a relatively fixed structure earlier, then utilizes shoulder 1 to wear to establish this device on the user of waiting to fall, then, manual control handle 4 to release stay cord 5, then make the user descend with the uniform velocity, and after descending to ground, take off this device can, thereby realized assisting the function of its whereabouts.

In order to improve the practicality of this device, set up stay cord 5 into wire rope, set up safety lock 6 into the intensity form that intensity is higher and can bear great weight user to can be applicable to the user of different sizes.

Speed adjusting mechanism is including locating 3 tip of pivot driving gear 7, with the reduction gear 8 of driving gear 7 meshing, wherein:

the rotating shaft 3 horizontally penetrates through the protective shell 2 through the end part of the rotating shaft, and the reduction gear 8 is rotatably connected to the protective shell 2 through a gear shaft 9;
