DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] The pipeline fixing bracket structure can control and adjust the direction and angle of the pipeline, making the pipeline more convenient and efficient during actual installation. At the same time, the pipeline fixing bracket structure has high structural strength, which can effectively ensure the stability and firmness of the pipeline installation.

[0018] Depend on Figures 1 to 5 The utility model includes a main block 1, and mounting plates 2 are fixedly installed on both sides of the main board 1. Bolt holes are opened in the middle of the two mounting plates 2, and are connected to the rail car through external bolts penetrating the bolt holes, so that the main board 1 can be stably and effectively installed on the rail car through the two mounting plates 2, and a rotatable and adjustable first rotating shaft 3 is installed at the bottom of the main board 1, and a connecting block 4 is fixedly connected to the bottom of the first rotating shaft 3, and a rotatable and adjustable second rotating shaft 5 is installed on one side of the connecting block 4, and one end of the second rotating shaft 5 is fixedly connected to a movable sleeve 6 for being sleeved on the surface of the pipeline, and both ends of the movable sleeve 6 are fixedly connected to bell-mouthed pieces 7. Through the setting of the bell-mouthed piece 7, the movable sleeve 6 will not cause damage to the surface of the pipeline when rotating and adjusting.

[0019] A rotation adjustment cavity 8 is provided in the middle of the main block 1 and the connecting block 4, and a worm gear 9 is provided inside the two rotation adjustment cavities 8. One end of the first rotating shaft 3 and the second rotating shaft 5 respectively extends into the two rotation adjustment cavities 8 and is fixedly connected to the worm gear 9. A worm 10 meshing with the worm gear 9 is rotatably connected inside the two rotation adjustment cavities 8. One end of the two worm gears 10 respectively extends to the outside of one side of the main block 1 and the connecting block 4 and is fixedly connected to a rotation nut 11, so that the connecting block 4 and the movable sleeve 6 can be effectively adjusted.

[0020] By rotating the rotating nut 11 on the main block 1, the worm 10 drives the worm wheel 9, so that the first rotating shaft 3 drives the connecting block 4 to rotate, and the rotation of the connecting block 4 drives the movable sleeve 6 to adjust the direction, so that the movable sleeve 6 sleeved on the surface of the pipeline drives the pipeline to adjust the direction;

[0021] By rotating the rotating nut 11 on the connecting block 4, the worm 10 drives the worm wheel 9 so that the second rotating shaft 5 drives the movable sleeve 6 to rotate. The rotation of the movable sleeve 6 drives the pipeline to adjust its angle.

[0022] The surfaces of the two rotating nuts 11 are provided with inverted convex through holes 12, and inverted T-shaped pins 13 are installed inside the inverted convex through holes 12. A rotating plate 14 is fixedly installed on one end of the inverted T-shaped pin 13, and a fixed plug 15 is fixedly installed on the other end of the inverted T-shaped pin 13. The fixed plug 15 is flat. One side of the main block 1 and the connecting block 4 is annularly provided with limit plug holes 16 matching the fixed plug 15 at equal distances, so that the rotating nuts 11 can be effectively limited and fixed. The inverted T-shaped pin 1 The surface at one end of the inverted convex through hole 12 is sleeved with a spring 17, and the surface at the other end of the inverted T-shaped pin 13 is fixedly mounted with a bayonet 18. The other end of the inverted convex through hole 12 is provided with a vertical groove 20 and an arc groove 19. The vertical groove 20 and one end of the arc groove 19 are connected, and the vertical groove 20 and the arc groove 19 are in a vertical state. The bayonet 18 is located inside the vertical groove 20, so that the control adjustment can be effectively performed to make the rotating nut 11 rotate and adjust;

[0023] When the rotating nut 11 needs to be rotated and adjusted, the inverted T-shaped pin 13 needs to be pulled and moved by the rotating plate 14, so that the latch 18 moves from the inside of the vertical slot 20 to the inside of the arc slot 19, and the movement of the inverted T-shaped pin 13 will drive the fixed latch 15 to move out of the inside of the limiting plug hole 16 and compress the spring 17, and then the plate 14 is rotated to make the latch 18 slide and snap into the end of the arc slot 19 away from the vertical slot 20. At this time, the fixed latch 15 will no longer snap into the inside of the limiting plug hole 16, and the rotating nut 11 can be effectively rotated and adjusted;

[0024] After the adjustment is completed, the rotating plate 14 is rotated in the opposite direction to move the latch 18 to the junction of the arc groove 19 and the vertical groove 20. Then, the elastic restoring force of the spring 17 causes the fixing pin 15 to be again inserted into the limiting socket 16 to limit and fix the rotating nut 11.

[0025] The pipeline fixing bracket has a simple structural design, is convenient and easy to use and operate, and is stable and reliable to adjust and fix. Its performance can meet the use requirements of pipeline installation and fixation for rail vehicles.
