Sealing mechanism of back door and bin body of trash bin

Abstract

The invention belongs to the field of bin body leakage-proof accessories of dust trucks and compression devices and particularly relates to a sealing mechanism of a back door and a bin body of a trash bin. The sealing mechanism is used on a trash compression station and comprises a sealing strip and a base used for connecting the sealing strip and the bin body. The bottom surface of the base and the corresponding matching surface of the bin body form a surface mounted sealing state, the upper portion of the base forms a matching portion used for forming clamping and embedding matching with the lower portion of the sealing strip, and the upper portion of the base and the sealing strip and / or the lower portion of the base and the bin body form detachable matching. By aid of a split detachable structure formed by the sealing strip and the base and / or the base and the bin body, fast and convenient mounting and demounting operation of the sealing mechanism relative to the bin body is achieved. The sealing mechanism is simple in structure and fast and convenient to mount, demount and maintain.

Description

technical field [0001] The invention belongs to the field of anti-leakage fittings for garbage trucks and compression equipment, in particular to a sealing mechanism for the back door of the garbage box on the garbage truck and the box body. Background technique [0002] Because urban garbage often contains a lot of water, when using garbage trucks for transportation, water leakage often occurs due to poor sealing between the back door of the car body and the box body; therefore, most existing garbage trucks use sealing mechanisms to achieve their sealing effect; this It is recorded in detail in the applicant's application for Chongqing Naide Xinminghe Industrial Co., Ltd., which is named "the structure of the back door seal of the rear-mounted compressed garbage truck" (application number: 200920294093.8): the seal includes the installation part and the deformation part, The installation part constitutes a trapezoidal base structure with a small bottom and a large top; a de...

AI Technical Summary

Problems solved by technology

Although the above-mentioned structure can partially realize its sealing properties, however, due to the presence of a large number of sharp and hard objects in the urban waste, whether it is in packing or unloading, it will first cause wear and tear to the sealing strip at the mouth of the box. It is also difficult to avoid the sharp reduction of its service life; therefore, the loading and unloading maintenance operations of the sealing strips are particularly important, and the direct welding design of the beading in the above structure is particularly difficult to disassemble. The bead and the installation part form an integral one-piece clamping structure, and the cooperation between them is very firm and tight. When the sealing strip is worn and needs to be replaced, the maintenance personnel must first rely on external force to forcibly break one side of the bead so that it is in contact with the other side. A gap is formed between the sealing strips so that the sealing strip can be pulled out, and at this time the strip replacement operation can be realized; and after the side of the installation part of the new sealing strip is against the one side of the pressing strip, the other side of the installation part needs to be fixed again. At this time, the overall maintenance operation can be completely realized. Its disassembly is inconvenient, time-consuming and laborious, and the maintenance operation efficiency is low. At the same time, the repeated breaking and welding of the bead on one side will lead to this part of the box. A large number of welding residues appear, which brings difficulties to the reliable welding of the next bead, thus causing great distress to the staff
