Sanitation brush with easy replacement of brush filaments

Abstract

The invention discloses a sanitation brush with easy-to-replace brush filaments, which includes a casing, a limiting track is arranged on the inner surface of the casing, and a bottom plate slidably connected with the limiting track is installed inside the casing. The bottom end of the outer surface is movably installed with a limit device that fits with the bottom plate, and a guide post is fixedly installed on the inner top of the housing. The bottom end of the guide post is provided with a slot, and the brush body is snapped into the slot The surface of the guide column is sleeved with a shock absorbing spring, and a spring groove is provided between the inner top of the housing and the top of the bottom plate, and the top of the bottom plate is also connected to a threaded rod through a rolling bearing transmission, and the top of the threaded rod runs through The shell is threadedly connected with a nut, and the top surface of the threaded rod is also threaded with a fastening nut. The device has a simple and reasonable structural design, is convenient to operate, is convenient to disassemble and replace, saves time and effort, reduces manufacturing costs, is safe and stable, has a wide range of applications, and is conducive to promotion and popularization.

Description

technical field [0001] The invention belongs to the technical field of sanitation brushes, in particular to a sanitation brush with easy-to-replace brush filaments. Background technique [0002] The sanitation brush is a brush made by drilling holes at a certain angle on the cut PP disc, and then using the cut flat steel wire or PP brush wire or nylon wire to fold in half and insert them in series. There are many types of sanitation brushes and the scope of application is also very wide. Widely used, disc brushes or steel wire disc brushes installed in municipal sanitation vehicles for cleaning streets are the most representative sanitation brushes. However, most of the existing sanitation brushes are fixed in structure, and the whole sanitation brush cannot be used after the brush filaments are inserted into the disc in a fixed manner to wear or fall off, which increases the manufacturing cost and is installed on the sanitation vehicle at the same time The overall replacem...

Problems solved by technology

However, most of the existing sanitation brushes are fixed in structure, and the whole sanitation brush cannot be used after the brush filaments are inserted into the disc in a fixed manner to wear or fall off, which increases the manufacturing cost and is installed on the sanitation vehicle at the same time The overall replacement of the sanitation brush also needs to be disassembled, which is not only troublesome to operate but also time-consuming and laborious, which is not conducive to extensive promotion and popularization
