Lifting mechanism

Abstract

The invention discloses a lifting mechanism, and relates to the technical field of conveying devices. The lifting mechanism specifically comprises a fluent strip, a stabilizing pipe assembly and a self-adaptive supporting assembly, a lifting air cylinder is rotationally connected to the middle of the bottom surface of the fluent strip, the stabilizing pipe assembly is arranged on the surface of a stabilizing supporting plate, an embedding groove is formed in a pipe body, absorbent cotton is bonded to the inner wall of the end, close to the vertical central axis of the pipe body, of the embedding groove, a silica gel nozzle is arranged in the other end of the embedding groove, and the self-adaptive supporting assembly is connected to the interior of an upper threaded groove. According to the lifting mechanism, sliding friction force is converted into rolling friction force, the possibility of blockage caused by friction between a guide rod and the pipe body is reduced, the retention time of lubricating oil can be prolonged by absorbing the lubricating oil through the absorbent cotton, and therefore the possibility of blockage is further reduced; and in addition, the lifting mechanism can rotate the fluent strip to adjust the inclination degree when lifting the fluent strip, and can still keep normal lifting of the fluent strip in an inclined state so as to better adapt to the working environment of a workshop.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a lifting mechanism. Background technique [0002] Fluent bar is the abbreviation of aluminum alloy slide rail. Because of its convenient and fast installation, the items placed on the top run smoothly and neatly. As the name implies, it is called a fluent strip. It is mostly used in the production workshop to transport products. It can further cooperate with the lifting mechanism to change the conveying height of the product. Better use of workshop space. [0003] In order to ensure the stability of the lifting mechanism, the existing fluent bar with a lifting mechanism will set a guide rod at the bottom of the fluent bar, and the guide rod will rise and fall in the tube body synchronously with the fluent bar, and the guide bar can only be lifted vertically due to the restriction of the tube body Thereby, the stability is improved, but since the guide rod moves up...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a lifting mechanism, which solves the problem that the existing fluent bar with a lifting mechanism proposed in the above-mentioned background technology is provided with a guide rod at the bottom of the fluent bar in order to ensure stable lifting, and the guide bar The rod moves up and down in the tube body synchronously with the fluent strip. The guide rod can only be lifted vertically due to the restriction of the tube body to improve stability. However, since the guide rod moves up and down inside the tube body, it is easy to cause friction with the inner wall of the tube body. , it is easy to cause the phenomenon of jamming, and thus the problem that the fluent bar cannot be raised and lowered
