Description

Technical Field

[0001] The utility model belongs to the technical field of hose safety protection, and particularly relates to a limiting device for a carbon dioxide filling hose. Background Technique

[0002] Carbon dioxide is a carbon oxide compound with the chemical formula CO₂. It is a colorless, odorless or colorless and odorless gas with a slightly sour taste in its aqueous solution at normal temperature and pressure. It is also a common greenhouse gas and a component of air. At the same time, if a person inhales too much carbon dioxide, there is a risk of asphyxiation or even death. When our company sells liquid carbon dioxide, it needs to be first filled into a mobile tank truck using a special low-temperature shielding pump, and then transported to the customer's site.

[0003] As shown in the on-site filling Figure 1 At least there are various hoses during filling, and two hoses are randomly laid on the ground. If there is still residual CO₂ liquid in the filling hose, pressure will be generated inside the hose, and the generated pressure will cause the hose to swing randomly, which is likely to hurt the operator and there is a safety hazard. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a limiting device for a carbon dioxide filling hose is proposed. The limiting device is installed at the rear of the mobile tank truck and beside the carbon dioxide tank. The hose is installed on the limiting device to avoid the situation of the hose swinging randomly.

[0005] The technical solution adopted by the utility model is:

[0006] A limiting device for a carbon dioxide filling hose, including a central column. Two horizontal support plates are movably connected to both sides of the central column. A column is arranged at the bottom of each of the two horizontal support plates. A limiting component is arranged above the two horizontal support plates, and the hose passes through the limiting component.

[0007] On the basis of the above technical solution, further, two hinge pieces are arranged on both sides of the central column. One end of the horizontal support plate is located between the two hinge pieces and is hinged to the two hinge pieces, and the column is arranged at the other end of the horizontal support plate.

[0008] On the basis of the above technical solution, furthermore, a pin hole is arranged at the bottom of the other end of the horizontal support plate, and a pin column is arranged at the top of the column, and the pin column is located in the pin hole.

[0009] On the basis of the above technical solution, further, the limiting component includes a U-shaped elastic steel sheet. One end of the U-shaped elastic steel sheet is provided with a hinge seat, and the other end is provided with a barb. The hinge seat is arranged on the horizontal support plate, and a limiting seat is also arranged on the horizontal support plate. A hook groove is arranged on one side of the limiting seat facing the hinge seat, and the barb is located in the hook groove.

[0010] On the basis of the above technical solution, further, the hinge seat is an inverted L-shaped block, and the hook groove is arranged on the horizontal section of the inverted L-shaped block.

[0011] Advantages of the present utility model:

[0012] 1. The carbon dioxide filling hose limiting device designed by the present utility model is composed of a central column, a horizontal support plate, a column and a limiting component. The limiting component is installed on the horizontal support plate, and the assembled limiting device is installed at the rear of the vehicle loading for limiting the hose. The hose can be separated from the human hand. At the same time, due to the limitation of the limiting component, even after the filling is completed, the residual liquid will not fly around with the hose and hurt the operator. In addition, most of the above structures are made of steel, which is simple to process and assembled with a hinge shaft or bolts. The whole assembly process is simple and fast, and it is worthy of full promotion in the factory.

[0013] 2. In the present utility model, the limiting component is composed of a U-shaped elastic steel sheet, a limiting seat and a hinge seat. One end of the U-shaped elastic steel sheet is bent reversely outward along its vertically downward direction to form a barb, and the other end is bent reversely outward along its vertically downward direction to form a cylinder. The cylinder is connected to the hinge seat through a hinge shaft. The U-shaped elastic steel sheet is simple to process and can be obtained. And the U-shaped elastic steel sheet can be deformed by pressing, so as to facilitate taking out its barb from the hook groove. The operator can conveniently open or close the U-shaped elastic steel sheet to install and obtain the hose. Description of the drawings
