AI Technical Summary
When the existing rail transit bend joints are used, there is no splicing structure at both ends of the rail pipe, the bending angle and length cannot be adjusted, and there is no separation structure inside, which causes the cable to be pushed and wound, making it difficult to pull, and affects heat dissipation.
A rail transit bend joint was designed, and the outer splicing ring sleeve was combined with the inner lined seal ring to realize splicing and splitting between the joints, and a three-point bent plate frame was installed in the inner lined seal ring to disperse the cables and avoid wrapping.
By splicing and splitting the structure, the bending angle and length are easily adjusted, and the installation process is simplified; the three-point bending plate frame separates the cables to prevent winding and improves the pull-out and heat dissipation effect of the cables.

The outer splicing ring sleeve 2 cooperates with the inner lining sealing ring 3 so that the rail transit elbow joints can be spliced and split, and the splicing and splitting process is simple and convenient, and can be adjusted according to the bending angle and length of the rail transit elbow joint, which is beneficial to the installation of the rail transit elbow joint. The three-part bending plate frame 4 can disperse the cables in the rail transit elbow joint, separate the cables, and avoid the cables being pushed and entangled together, which is not easy to pull, and the cables will be deformed, which will affect the heat dissipation of the cables.
[0022] The outer splicing circular ring sleeve 2 includes an outer circular ring sleeve body 201 and an internal threaded circular ring 202; the outer circular ring sleeve body 201 is fixedly installed on the rear surface of the track elbow pipe joint body 1, and the internal threaded circular ring 202 is fixedly installed on the inner wall of the outer circular ring sleeve body 201 at the rear end; the lining sealing circular ring 3 includes an inner lining circular ring body 301, an external threaded circular ring 302, a filling sponge circular ring 303 and a sealing rubber circular ring 304; the inner lining circular ring body 301 is fixedly installed on the front surface of the track elbow pipe joint body 1, and the external threaded circular ring 302 is fixedly installed on the front surface of the inner lining circular ring body 301; the filling sponge circular ring 303 is fixedly installed on the outer side of the inner lining circular ring body 301, and the sealing rubber circular ring 304 is fixedly installed on the outer side of the filling sponge circular ring 303; an annular groove is provided on the outer side of the sealing rubber circular ring 304, and two annular grooves are provided on the outer side of the sealing rubber circular ring 304, and the sealing rubber circular rings 304 are evenly distributed on the outer side thereof.
