DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a locking type pull rod structure on a pull rod box, comprising a box body 1, a box cover 2 is provided on one side of the box body 1, a plurality of pulleys 4 are connected under the box cover 2, an auxiliary frame 3 is connected inside the box body 1, a stretching rod 5 is slidably connected inside the auxiliary frame 3, a handle 6 is connected to the stretching rod 5, a convex block 7 is slidably connected inside the handle 6, a positioning rod 8 is provided inside the handle 6, a rotating plate 9 is rotatably connected outside the positioning rod 8, a spring 11 is provided under the convex block 7, and a moving rod 10 is slidably connected inside the handle 6;

[0022] A card slot plate 12 is connected to the auxiliary frame 3, the rotating plate 9 is overlapped in the moving rod 10, the protrusion 7 is connected to the rotating plate 9, and the protrusion 7 is connected to the handle 6 through a spring 11. By setting the spring 11, when the protrusion 7 is pressed, the protrusion 7 slides in the handle 6, which drives the spring 11 to deform, so that the spring 11 plays a certain supporting role for the movement of the protrusion 7. When the protrusion 7 loses resistance, it will be reset by the spring 11;

[0023] A sleeve plate 13 is connected under the stretching rod 5, a guide rod 14 is rotatably connected inside the sleeve plate 13, a clamping plate 15 and a gear 17 are connected outside the guide rod 14, a tooth plate 18 is connected under the moving rod 10, and a fixed sleeve 19 is connected outside the handle 6. By setting the stretching rod 5, when the moving rod 10 is affected by a thrust or a pull, the tooth plate 18 below the moving rod 10 will slide inside the stretching rod 5, so that the stretching rod 5 plays a certain guiding role in the movement of the moving rod 10 and the tooth plate 18, thereby preventing the moving rod 10 and the tooth plate 18 from getting stuck when moving;

[0024] A rotating rod 20 is rotatably connected inside the fixing sleeve 19, and a protective plate 21 is connected outside the rotating rod 20. A mounting block 22 is connected to one side of the protective plate 21, and a bolt 23 is arranged inside the mounting block 22. The protective plate 21 is overlapped on the handle 6, and the mounting block 22 is connected to the handle 6 through the bolt 23. By providing the protective plate 21, when the protective plate 21 is connected above the handle 6, the protective plate 21 can play a certain auxiliary role for the protrusion 7, so as to prevent the protrusion 7 from accidentally hitting and causing the pull rod to become loose;

[0025] A coil spring 16 is connected to the outer sleeve of the guide rod 14, the card plate 15 is clamped with the slot plate 12, the card plate 15 is connected to the sleeve plate 13 through the coil spring 16, the gear 17 is meshed with the tooth plate 18, and the gear 17 is rotatably connected in the sleeve plate 13. By setting the coil spring 16, when the card plate 15 rotates around the guide rod 14, the card plate 15 will drive the coil spring 16 to deform, so that the coil spring 16 plays a certain limiting role in the rotation of the card plate 15. When the card plate 15 is restored, the coil spring 16 will apply thrust to it, thereby improving the stability of the card plate 15 and the slot plate 12 after being clamped.

[0026] The working principle of the utility model is:

[0027] When the pull rod is adjusting the height, pressure can be applied to the protrusion 7. When the protrusion 7 slides in the handle 6, it will drive the rotating plate 9 to rotate around the positioning rod 8, and the protrusion 7 will drive the spring 11 to deform when it is squeezed. When the rotating plate 9 rotates, it will drive the moving rod 10 to move. Since the toothed plate 18 is meshed with the gear 17, the gear 17 will drive the guide rod 14 to rotate when the toothed plate 18 moves, and the card plate 15 will rotate around the guide rod 14. When the card plate 15 rotates, it will drive The coil spring 16 is deformed, and then the stretching rod 5 is pulled through the handle 6. When the height adjustment of the handle 6 is completed, the protrusion 7 is released, the protrusion 7 will be reset by the action of the spring 11, and the clamping plate 15 will be restored by the action of the coil spring 16. The restored clamping plate 15 will be clamped with the corresponding groove point of the clamping plate 12. When the height adjustment is completed, the protective plate 21 is driven to rotate around the rotating rod 20. After the protective plate 21 is overlapped on the top of the handle 6, the mounting block 22 will be connected to the handle 6 through the bolt 23.
