Telescopic arm adjusting mechanism

Abstract

The invention discloses a telescopic arm adjusting mechanism, which comprises a front telescopic arm, a lead screw assembly, a rear telescopic arm and a handle assembly, wherein the front telescopic arm is fixedly connected with the lead screw assembly, the lead screw assembly is composed of a lead screw, a support sliding block, a nut seat, a nut, an intermediate bearing seat and a bearing, the nut seat is fixedly arranged at the front end of the lead screw, the nut is arranged in the nut seat, the lead screw is fixedly connected with the front telescopic arm, the rear telescopic arm is fixedly provided with the intermediate bearing seat, the bearing is installed in the intermediate bearing seat, the handle assembly and the lead screw are connected through the bearing, and the handle assembly is composed of a handle rod and a handle. According to the telescopic arm adjusting mechanism, the nut matched with the lead screw in use is fixed on the front telescopic arm, and the handle is fixedly connected with the rear end of the lead screw, thereby realizing a mechanism for manually adjusting extension and retraction of a telescopic arm, and solving a problem of telescopic arm adjustment which cannot be realized by a hydraulic cylinder under the same temperature and environment.

Description

technical field [0001] The invention relates to the technical field of telescopic arm adjustment mechanisms, in particular to a telescopic arm adjustment mechanism. Background technique [0002] At present, most telescopic arm adjustment mechanisms use hydraulic cylinders to control extension or retraction. Although it saves time and effort, due to the influence of temperature and environment on the hydraulic oil, it cannot be used in specific environments. Some manual telescopic arm adjustment mechanisms are simply wires. The rod and the screw nut are used in conjunction, and parts such as bearings are not installed, so it is inconvenient to operate. Contents of the invention [0003] The object of the present invention is to provide a telescopic arm adjustment mechanism for manually adjusting the extension or retraction of the telescopic arm, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, t...

[0002] At present, most telescopic arm adjustment mechanisms use hydraulic cylinders to control extension or retraction. Although it saves time and effort, due to the influence of temperature and environment on the hydraulic oil, it cannot be used in specific environments. Some manual telescopic arm adjustment mechanisms are simply wires. The combination of the rod and the screw nut is used without installing bearings and other parts, so it is inconvenient to operate
