a joint connecting device is characterized by comprising: the pipe comprises a nylon pipe body, a bamboo joint, a sleeved pipe and a nylon reinforcing sleeve, wherein the diameter of the outer pipe wall of the nylon pipe body is the same as that of the inner pipe wall of the bamboo joint, the bamboo joint is sleeved on the outer wall of the nylon pipe body, the outer wall of the bamboo joint is provided with a plurality of bamboo joint threads surrounding the outer wall of the bamboo joint, the diameter of the top of each bamboo joint thread is smaller than that of the bottom of each bamboo joint thread, the sleeved pipe comprises a sleeved part and a sleeved pipe body, the diameter of the sleeved part is larger than that of the sleeved pipe body, the diameter of the sleeved part is the same as that of the outer wall of the bamboo joint, the nylon reinforcing sleeve is sleeved on the sleeved part, and the diameter of the inner wall of the nylon reinforcing sleeve is the same as that of the outer wall of the sleeved part.
Preferably, the length of the nylon reinforcing sleeve is 15-25 mm.
Preferably, the sleeved pipe is a nylon pipe.
Preferably, the material of the nylon tube body is nylon 11.
Preferably, the material of the nylon tube body is nylon 12.
Preferably, the material of the nylon reinforcing sleeve is nylon 11.
Preferably, the material of the nylon reinforcing sleeve is nylon 12.
The positive progress effects of the invention are as follows: the bamboo joint connector and the nylon reinforcing sleeve are adopted at the pipeline connector for sealing, so that the pressure resistance of the connector connection part of the automobile pipeline is enhanced.

Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
Examples
A splice connection device comprising: nylon pipe body 1, bamboo joint 2, quilt cover is taken over 3, nylon reinforcement cover 4. The diameter of the outer pipe wall of nylon body 1 is the same with the diameter of the interior pipe wall of bamboo joint 2, and bamboo joint 2 cup joints the outer wall in nylon body 1, and bamboo joint 2's outer wall has a plurality of bamboo joint screw threads 21 that encircle bamboo joint 2 outer wall, and the diameter of bamboo joint screw thread 21 top and bottom is inequality, and the diameter at the top of bamboo joint screw thread 21 is less than the diameter of its bottom. By the muff-coupling pipe 3 including the portion 31 of cup jointing and by the muff-coupling pipe body 32, the diameter of the portion 31 of cup jointing is greater than the diameter of the body 32 of quilt cover-coupling pipe, and the diameter of the portion 31 of cup jointing is the same with the diameter of the outer wall that the bamboo joint connects 2, and nylon reinforcement sleeve 4 cup joints in the portion 31 of cup jointing, and the diameter of the inner wall of nylon reinforcement sleeve 4 is the same with the diameter of the outer wall of the portion 31 of cup jointing. The length of the nylon reinforcement sleeve 4 is 15-25 mm. The sleeved pipe 3 is a nylon pipe. The nylon tube body 1 is made of nylon 11 and nylon 12. The nylon reinforcing sleeve 4 is made of nylon 11 and nylon 12.
During the use, with bamboo joint 2 nestification in the outer wall of nylon tube body 1, in order to play better sealed effect, can paint sealed glue at the inner wall of bamboo joint 2 and the junction position of the outer wall of nylon tube body 1. Then the sleeve joint part 31 of the quilt sleeve joint pipe 3 is sleeved on the outer wall of the bamboo joint connector 2, and the bamboo joint connector thread 21 on the outer wall of the bamboo joint connector 2 forms a barb-like form, so that the quilt sleeve joint pipe 3 can be fixed. And finally, sleeving the nylon reinforcing sleeve 4 at the sleeving part 31 of the sleeved pipe 3, and fixing the nylon reinforcing sleeve 4 by using a special tool to realize a better sealing effect.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
