Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a new technical solution: a pantograph insulating hose mounting assembly, including an insulating hose body 1, a mounting head 2 is fixedly installed at the front end of the insulating hose body 1, a fixing head 3 is arranged on the front surface of the mounting head 2, and first mounting plates 4 are fixedly installed at both the left and right ends of the fixing head 3;

[0026] A mounting mechanism is arranged on the first mounting plate 4. The mounting mechanism includes two motors 5 and two connecting rods 6. First mounting grooves 7 are respectively opened inside the two first mounting plates 4. The two motors 5 are respectively fixedly installed inside the two first mounting grooves 7. First circular grooves 8 are respectively opened on the rear surfaces of the two first mounting plates 4. The two connecting rods 6 are respectively slidably installed on the inner walls of the two first circular grooves 8. Second mounting plates 9 are fixedly installed at both the left and right ends of the two mounting heads 2. The rear ends of the two first circular grooves 8 respectively extend into the two second mounting plates 9. The two connecting rods 6 are respectively rotatably connected to the inner walls of the two first circular grooves 8 on the rear second mounting plates 9.

[0027] Further, the installation mechanism further includes two threaded rods 10. Convex grooves 12 are formed on the front inner walls of the two second mounting plates 9, and the front ends of the two convex grooves 12 extend into the two first mounting plates 4. The two threaded rods 10 are respectively fixedly installed on the output ends of the two motors 5. The two threaded rods 10 are respectively threadedly connected to the corresponding connecting rods 6. Second circular grooves 13 are formed on the rear surfaces of the two threaded rods 10. Convex plates 14 are rotatably installed in the two second circular grooves 13. The vertical plates of the convex plates 14 are circular, and the two convex plates 14 are respectively fixedly connected to the corresponding connecting rods 6.

[0028] Further, limiting and fixing plates 11 are fixedly installed on the rear surfaces of the two connecting rods 6. The two limiting and fixing plates 11 are respectively slidably connected to the inner walls of the two convex grooves 12.

[0029] Further, limiting plates 15 are fixedly installed at the rear ends of the inner walls of the two second circular grooves 13.

[0030] Further, the motor 5 drives the connecting rod 6 and the limiting and fixing plate 11 to enter the convex groove 12, and then the connecting rod 6 and the threaded rod 10 are relatively fixed by the limiting plate 15, so that the limiting and fixing plate 11 can rotate inside the convex groove 12, so that the limiting and fixing plate 11 is fixed inside the convex groove 12, reducing the installation time of the insulating hose, thereby reducing the installation difficulty of the insulating hose, improving the working efficiency of the workers, and improving the use efficiency of the pantograph.

[0031] Further, a second installation groove 16 is formed on the inner wall of the installation head 2. An inflatable sealing ring 17 is installed inside the second installation groove 16. An air valve 18 is fixedly installed at the upper end of the inflatable sealing ring 17. The air valve 18 communicates with the inside of the inflatable sealing ring 17, and the inflating end of the air valve 18 extends to the upper surface of the installation head 2.

[0032] Further, the inside of the inflatable sealing ring 17 is inflated through the air valve 18, so that the inflatable sealing ring 17 expands, thereby sealing the connection between the installation head 2 and the fixed head 3. During installation, the inflatable sealing ring 17 has less air inside and does not shrink the inner wall of the installation head 2. When the fixed head 3 is butted with the installation head 2, it is convenient for installation, thereby further reducing the installation difficulty of the insulating hose.

[0033] Further, the same installation head 2 and fixed head 3 are fixedly installed at the rear end of the insulating hose body 1.

[0034] Working principle: When using this installation component, the installation heads 2 at both left and right ends of the insulating hose body 1 can be directly brought into contact with the two fixed heads 3 respectively, and the convex tubes on the two fixed heads 3 are inserted into the interiors of the two installation heads 2. Then, start the motors 5 on the two fixed heads 3. The motors 5 rotate, driving the threaded rods 10 fixedly connected to their output ends to rotate. The rotation of the threaded rods 10 drives the connecting rods 6 threadedly connected thereto to move. The convex plates 14 fixedly installed on the connecting rods 6 move forward inside the second circular grooves 13 as the connecting rods 6 move. At the same time, when the limit fixing plates 11 on the connecting rods 6 reach the vertical grooves of the convex grooves 12, at this time, the rectangular plates on the convex plates 14 are in contact with the limit plates 15 inside the second circular grooves 13, so that the threaded rods 10 and the connecting rods 6 are relatively fixed through the convex plates 14. At this time, continue to rotate the motors 5, so that the threaded rods 10 drive the connecting rods 6 to rotate. The limit fixing plates 11 fixedly installed on the connecting rods 6 rotate inside the convex grooves 12, so that the limit fixing plates 11 and the horizontal grooves of the convex grooves 12 are no longer corresponding. Then, stop the rotation of the motors 5, so that the connecting rods 6, the limit fixing plates 11 and the threaded rods 10 fix the first mounting plate 4 and the second mounting plate 9, thereby fixing the installation heads 2 and the fixed heads 3 to install the insulating hose and reducing the installation difficulty of the insulating hose. Then, inflate the inside of the inflatable sealing ring 17 through the valve nozzle 18, so that the inflatable sealing ring 17 expands, thereby sealing the connection between the installation head 2 and the fixed head 3 and further reducing its installation difficulty.
