Problems solved by technology

[0002] At present, most of the suction arms on the market are built-in brackets. Since the joints and brackets are in the ventilation duct, the ventilation resistance is relatively large, and the built-in joints and brackets are polluted by dust and soot, resulting in cumbersome operation and limited service life.
[0003] However, the vertical rotation structure of the suction arm of the traditional external support has defects. When the vertical rotation center of the suction arm deviates from the vertical position, it will swing due to gravity, which will affect normal use.
In addition, the traditional external support suction arm does not have a set of reasonable balance and friction damping mechanism. It cannot be easily operated while ensuring reliable hovering at any position during use. Frequent adjustments are required, which greatly affects the work. efficiency

Abstract

The invention discloses a universal air suction arm with an external support. The universal air suction arm comprises a fixing structure, a shoulder cross arm, an upper arm support and a forearm support, wherein the upper arm support is fixed to the fixing structure through a shoulder joint and the shoulder cross arm; an upper arm hard pipe is installed above the upper arm support; the left end of the upper arm hard pipe is connected with a shoulder hose; the forearm support is connected to the right side of the upper arm support through an elbow joint; a forearm hard pipe is installed above the forearm support; the forearm hard pipe and the upper arm hard pipe are connected through an elbow hose; and the right side of the forearm hard pipe is sequentially connected with a wrist hose and a fan cover through a wrist joint and a handle. A working range adjusting device is arranged at the shoulder joint, so that the working range can be rotated downwards or upwards by a certain angle to meet the requirements of different use occasions; and the wrist joint is a universal connecting piece and is provided with a simple and practical adjustable friction damping device, so that stable performance can be ensured for a long time, and the fan cover is convenient in direction adjustment and stable in hovering.

Description

Technical field [0001] The present invention relates to the field of environmentally friendly, and is specifically an external stent universal suction arm. Background technique [0002] At present, there is a suction arm in the market, most of which are built-in brackets. Due to joint and brackets in the ventilation pipeline, the ventilation resistance is large, the dust hood is contaminated in the inner joint and brackets, resulting in a cumbersome operation, limited service life. [0003] The vertical rotation structure of the traditional external stent suction arm is defective, and the oscillating phenomenon is generated due to gravity when the intake arm vertically rotates from the vertical position, affecting normal use. In addition, traditional external stent suction arms, there is no reasonable balance and friction damping mechanism, which cannot be operated during use, while ensuring that it is reliable in any position, it requires frequent adjustment, great impact effici...
