Liquid adding pipe assembly

Abstract

The utility model provides a liquid adding pipe assembly, and belongs to the technical field of liquid adding pipe fittings. The problem that the joint of an existing liquid adding pipe and a connector is prone to assembly deformation is solved. The liquid adding pipe assembly comprises a liquid adding pipe body and a connector body connected with the liquid adding pipe body, and a sunken groove which is sunken inwards in the axial direction and is of a polygonal structure is formed in the end face, located at the end connected with the connector body, of the liquid adding pipe body. The liquid adding pipe body is located in the concave groove and is provided with a shape-preventing unit which is in sliding fit with the concave groove and used for improving the deformation-preventing capacity. The anti-deformation structure has the advantage of improving the anti-deformation effect.

Description

Technical Field

[0001] This utility model belongs to the technical field of liquid filling pipe fittings, and relates to a liquid filling pipe assembly. Background Technology

[0002] Liquid filling pipes are commonly used to transport liquids and gases, and therefore have a relatively wide range of applications. The connector is an important component of the liquid filling pipe. When connecting the two, if excessive force is applied, it can easily cause deformation at the connection point, which may create gaps and result in an untight connection. This affects the sealing performance of the connection. Once leakage occurs, it can easily lead to unstable pressure inside the pipe, causing the pipe to crack and affecting subsequent use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a liquid filling tube assembly that reduces deformation.

[0004] The purpose of this utility model can be achieved through the following technical solution: a liquid filling tube assembly, including a liquid filling tube body and a connector body connected to the liquid filling tube body, characterized in that the liquid filling tube body has an axially inwardly recessed groove with a polygonal structure on the end face of the end connected to the connector body, and the liquid filling tube body is provided with a deformation-resistant unit in the recessed groove for sliding cooperation and for improving the deformation resistance.

[0005] In the above-mentioned liquid filling tube assembly, the anti-deformation unit includes an assembly column and several inserts. The assembly column is also arranged in a polygonal structure. The side wall of the assembly column is provided with an installation groove for installing the corresponding insert. The inserts abut against the groove wall corresponding to the recessed groove through the assembly column.

[0006] Compared with existing technologies, this liquid filling pipe assembly improves its deformation resistance by creating recessed grooves and setting anti-deformation units in the recessed grooves. Attached Figure Description

[0007] Figure 1 This is a cross-sectional view of the liquid filling tube assembly.

[0008] In the diagram, 1 is the main body of the liquid filling tube; 2 is the assembly column; and 3 is the insert. Detailed Implementation

[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] like Figure 1As shown, this liquid filling tube assembly includes a liquid filling tube body 1 and a connector body connected to the liquid filling tube body 1. The end face of the liquid filling tube body 1 connected to the connector body has an axially inwardly recessed, polygonal groove. The liquid filling tube body 1 has a deformation-resistant unit that slides within the recessed groove and is used to improve deformation resistance. The deformation-resistant unit includes an assembly post 2 and several inserts 3. Several through holes are spaced along the length of the inserts 3. The inserts 3 can be made of elastic material. The assembly post 2 also has a polygonal structure. Each side wall of the assembly post 2 has an installation groove for installing the corresponding insert 3. The inserts 3 abut against the corresponding groove wall of the recessed groove through the assembly post 2. The length of the installation groove can be less than the length of the assembly post 2, and the installation groove is located at the inner end of the assembly post 2. The liquid filling tube body 1 has a polygonal ring at the outer end of the recessed groove that is connected to and matches the recessed groove. After assembly, the polygonal ring abuts against the inserts 3.

[0011] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0012] Although this document uses terms such as "etc." extensively, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
