Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a two-color HDPE pipe with life indication and anti-loosening functions. Background Art

[0002] In industrial production, pipes are widely used. However, existing pipes have some problems during use. On the one hand, it is difficult to accurately judge the service life of the pipe, and it is often necessary to rely on experience or regular inspections, which may lead to untimely maintenance, causing safety hazards and equipment damage. On the other hand, when HDPE pipes are matched with roller bearing seats, loose rotation is prone to occur, affecting the normal operation of the equipment. Therefore, a two-color HDPE pipe with life indication and anti-loosening function is proposed to solve this problem of roller use. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a two-color HDPE pipe with life indication and anti-loosening function, which is intended to assist in judging the use loss of the pipe.

[0004] To achieve the above-mentioned purpose, the present utility model provides the following technical solution: a two-color HDPE pipe with life indication and anti-loosening function, including a pipe body, characterized in that: the pipe body is divided into an outer layer and an inner layer, the outer layer and the inner layer are integrally formed, and the thickness of the outer layer is greater than the thickness of the inner layer, and the inner wall of the inner layer is provided with ribs.

[0005] Preferably, the outer layer and the inner layer are both made of HDPE material, and the outer layer and the inner layer are divided into two colors, and the outer layer adopts dark colors, such as blue, brown and black, and the inner layer adopts bright colors, such as red, yellow, etc. The setting of the bright color of the inner layer serves as an intuitive warning for wear.

[0006] The utility model has the following beneficial effects:

[0007] 1. In this utility model, the pipe body adopts an integrally molded two-color layered design. The difference in color between the inner and outer layers can be used to intuitively judge the service life of the pipe, making it convenient for maintenance personnel to find problems in time and replace them, avoiding safety hazards and equipment damage caused by inadequate maintenance.

[0008] 2. In the present invention, the protruding ribs on the inner wall of the tube body can fit tightly with the roller bearing seat, effectively preventing the bearing seat and the tube from loosening and rotating, thereby improving the stability and reliability of the equipment.

[0009] 3. The pipe body does not need to be tested and analyzed in a complicated manner to quickly determine whether the pipe needs to be replaced. At the same time, it reduces the maintenance work due to loose rotation and improves the efficiency of inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] Reference Figure 1 The utility model provides an embodiment: comprising a tube body 1, the tube body 1 is divided into an outer layer 2 and an inner layer 3, the outer layer 2 and the inner layer 3 are integrally formed, and the thickness of the outer layer 2 is greater than the thickness of the inner layer 3, and the inner wall of the inner layer 3 is provided with ribs 4.

[0015] Specifically, the outer layer 2 and the inner layer 3 are both made of HDPE material. The outer layer 2 and the inner layer 3 are divided into two colors, and the outer layer 2 adopts dark colors, such as blue, brown and black, while the inner layer 3 adopts bright colors, such as red, yellow, etc. The setting of the bright color of the inner layer serves as an intuitive warning for wear.

[0016] Working principle: Install the two-color HDPE pipe body 1 on the roller so that the rib 4 fits tightly with the bearing seat. During use, regularly check the appearance of the pipe to see if the inner wall color is visible. When the pipe is found to be worn to the point where the color of the inner layer 3 is visible, replace it with a new one in time.

[0017] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
