Description

TECHNICAL FIELD

[0001] The utility model belongs to rubber pipe technical field, especially relate to the flame -retardant rubber pipe. BACKGROUND

[0002] The rubber pipe is a tubular product made of rubber as the main material, and the rubber pipe can restore to the original shape after being stressed, which makes it perform well in various applications requiring bending, stretching or compression. The rubber material can effectively prevent the leakage of gas or liquid, so the rubber pipe is often used in occasions requiring sealing.

[0003] For example, the Chinese patent with the announcement number CN215981169U discloses a high-strength rubber pipe, which comprises a pipe body and a base. A fixing belt is arranged on the base, and the pipe body is arranged in the fixing belt. A groove is arranged on the top surface of the base and matches the pipe body. A flat plate is arranged at the bottom of the base. A male buckle is arranged on one side wall of the flat plate, and a female buckle is arranged on the other side wall of the flat plate. A first through hole is arranged on the male buckle, and a second through hole is arranged on the female buckle. A bolt is arranged in the first through hole and the second through hole. The high-strength rubber pipe can effectively prevent the pipe body from being damaged due to friction with the ground and can effectively prevent the pipe body from moving randomly. In addition, the high-strength rubber pipe can effectively prevent the collision between adjacent two pipe bodies through the setting mode of the male and female buckles, which greatly improves the service life of the rubber pipe.

[0004] The above-mentioned patent has the following problems:

[0005] The patent has some shortcomings when in use, such as: when the rubber pipe is used to transport flammable liquid, adjacent two rubber pipes may collide, and the pipe body may be damaged due to friction with the ground. The above-mentioned device uses a fixing belt to fix the position of the rubber pipe. When the rubber pipe is installed, the personnel need to wrap two fixing belts on the rubber pipe in turn, and then pull tightly. If the fixing belt is not pulled tightly, the rubber pipe may not be fixed firmly, which affects the fixing effect of the rubber pipe. At the same time, the above-mentioned device uses a male and female buckle to fix the position of multiple rubber pipes. In a vibrating or impacting environment, the male and female buckles may be loose or fall off, which may cause the connection to fail. In view of this, we propose the flame-retardant rubber pipe.
