Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safety devices and relates to a descending device, in particular to a descending device that prevents accidental touch. Background Art
[0002] A descender is a safety rescue device that allows a person to slowly descend along a rope. This device is commonly used for high-rise escapes. It works by using the descending rope to drive the planetary gear reduction mechanism within the main unit, creating friction with the friction blocks within the friction wheel hub, ensuring a safe and slow descent to the ground.
[0003] The control handle of the common descender on the market controls the cam to achieve control of the friction between the cam and the rope. The handle is a lever structure, which makes the control of the cam more labor-saving. However, the longer control handle protrudes from the main body of the descender, which can easily lead to accidental touch and slip during use. Summary of the Invention
[0004] The purpose of the utility model is to solve the above problems existing in the prior art and provide an anti-mistaken touch descending device with wide adaptability and simple operation.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a descent control device that prevents accidental touch, characterized in that it includes a descent control device body with a locking cam provided inside, and a control handle connected to the locking cam is provided on the descent control device body, characterized in that a rotatable locking wrench is provided on the control handle, and a transfer shaft is provided between the locking wrench and the control handle, a pressing part is provided at one end of the locking wrench, and a locking part is provided at the other end of the locking wrench, a limiting boss of a limiting locking part is provided on the descent control device body, a support spring is provided between the locking wrench and the control handle, and a chip removal through hole is provided on the side wall of the descent control device body.
[0006] In the above-mentioned anti-accidental-touch descending device, a connecting shaft is provided between the locking wrench and the control handle.
[0007] In the above-mentioned anti-accidental-touch descending device, spring mounting holes are provided on the pressing portion and the side wall of the control handle, and the spring mounting holes are arranged opposite to each other.
[0008] In the above-mentioned anti-accidental-touch descending device, a weight-reducing cavity is provided at the center of the control handle, and a through groove for installing a locking wrench is provided on the side wall of the weight-reducing cavity.
[0009] Compared with the existing technology, this anti-accidental-touch descender increases safety during use by adding a locking wrench to the control handle to prevent the control handle from slipping due to accidental touch when locked. The locking button on the control handle comes into contact with the operator's palm during descent, reducing the operating process and making it easier to use. The chip removal holes on the side wall of the descender body allow foreign matter to accumulate inside, preventing foreign matter from reducing the friction of the rope, making the descender adaptable to more usage scenarios. The weight-reducing groove at the beginning of the control handle can also accommodate the locking wrench when pressed, reducing protrusions and improving comfort. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0017] like Figure 1As shown, the present invention is characterized in that it comprises a descender body 5 with a locking cam 4 provided inside, a control handle 1 connected to the locking cam 4 is provided on the descender body 5, a movable and rotatable locking wrench 2 is provided on the control handle 1, a rotation shaft is provided between the locking wrench 2 and the control handle 1, a pressing portion 13 is provided at one end of the locking wrench 2, and a locking portion 9 is provided at the other end of the locking wrench 2, a limiting boss 10 for limiting the locking portion 9 is provided on the descender body 5, and a locking wrench 2 is provided between the locking wrench 2 and the control handle 1. There is a support spring 7, and a chip removal hole 3 is opened on the side wall of the descender body 5. When descent is required, the operator holds the control handle 1 with his hand, and the pressing part 13 is set in the palm. When driving the control handle 1, the palm presses the pressing part 13 at the same time to unlock it, reducing the operation process. After the rope is in contact and squeezed with the descender body 5, foreign matter attached and stretched will fall off, and the chip removal hole will discharge foreign matter to reduce the slippage of the rope caused by the accumulation of foreign matter. At the same time, it can also accelerate heat dissipation and prevent the reduction of friction caused by rapid friction.
[0018] Preferably, a connecting shaft 12 is provided between the locking wrench 2 and the control handle 1 .
[0019] Preferably, spring mounting holes 8 are provided on the pressing portion 13 and the side wall of the control handle 1 , and the spring mounting holes 8 are arranged opposite to each other.
[0020] Preferably, a weight-reducing cavity 11 is provided at the center of the control handle 1 , and a through groove 6 for installing the locking wrench 2 is provided on the side wall of the weight-reducing cavity 11 .
[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
[0022] Although this document frequently uses terms such as control handle 1, locking wrench 2, chip removal hole 3, locking cam 4, descending device body 5, through-groove 6, support spring 7, spring mounting hole 8, locking portion 9, limiting boss 10, weight-reducing cavity 11, connecting shaft 12, and pressing portion 13, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
