A sealed connection structure and assembly and disassembly method of a liquid bag in a carriage

Abstract

The invention provides a carriage liquid bag sealing connection structure and a disassembly and assembly method, and belongs to the field of modern traffic equipment. The carriage liquid bag sealing connection structure and the disassembly and assembly method solve the problems that a liner barrel of a common liquid bag cannot be fixed and the sealing effect is poor in an existing liquid food transport vehicle. The carriage liquid bag sealing connection structure is used for sealing connecting a liner barrel to a charging and discharging barrel; the inner wall of the charging and discharging barrel is provided with a sealing groove; the carriage liquid bag sealing connection structure further comprises a sealing connection device provided with a sealing sleeve, an operating sleeve and a positioning sleeve; the positioning sleeve is arranged on the outer wall of the operating sleeve in a sleeving mode; the sealing sleeve is arranged on the positioning sleeve a sleeving mode; the top endof the sealing sleeve is provided with a sealing ring; the outer wall of the operating sleeve is provided with main sliding grooves; the inner wall of the sealing ring is provided with main sliding blocks; the sleeve wall of the positioning sleeve is provided with positioning holes; connecting grooves are formed in the outer wall of the operating sleeve; auxiliary sliding grooves are formed in the groove walls of the connecting grooves; the structure also comprises connecting pieces arranged in the positioning holes in a penetrating mode; auxiliary sliding blocks are fixed on the connecting pieces; a main sealing ring is arranged at the bottom end of the sealing sleeve; and an auxiliary sealing ring is arranged on the groove wall of the sealing groove. The sealing connection structure issuitable for the common liquid bag, and has a better sealing effect.

Description

technical field [0001] The invention belongs to the technical field of modern transportation equipment, and relates to a sealed connection structure of a fluid bag in a carriage and an assembly and disassembly method. Background technique [0002] Existing food transport vehicles with liquid bags placed in the compartment use the inlet and outlet of the liquid bag to feed in and out, but during transportation, the carriage will vibrate and cause the inlet and outlet to deviate. [0003] The application number is 201610351299.4, which is a Chinese invention patent titled "Quick disassembly structure of liquid bag for liquid food transport vehicle". The sleeve uses the pin groove on the outer sleeve to cooperate with the spring pin on the inlet and outlet barrel to play a fixed role, and it is convenient and quick to disassemble, but it has the following problems: [0004] 1. There must be a gap between the outer sleeve and the inlet and outlet barrels so that the outer sleev...

AI Technical Summary

Problems solved by technology

[0004] 1. There must be a gap between the outer sleeve and the inlet and outlet barrels so that the outer sleeve can be loaded into the inlet and outlet barrels, but liquid food can easily flow into the liquid bag and the compartment from the gap between the outer sleeve and the inlet and outlet barrels , resulting in contamination of the compartment and food contamination in the flexitank;

[0005] 2. In order to adapt to the inlet and outlet barrels with spring pins, an additional outer sleeve must be installed on the liner of each liquid bag, so it is not suitable for liquid bags with ordinary liners, and the versatility is poor
