[0022] See also Figure 1 and Figure 2 , an embodiment provided by the utility model: a three-wheeled vehicle dump bucket limiting structure;

[0023] It includes a mounting frame 1 and a control switch assembly. A mounting hole 3 is provided at the top of one end of the mounting frame 1. A control switch assembly is installed at the bottom of the mounting frame 1. The control switch assembly is used to cut off the power of the hydraulic cylinder on the tipping bucket of the tricycle. The control switch assembly includes a controller 4. The controller 4 is installed at the bottom of the mounting frame 1, and the top of the controller 4 passes through the top of the mounting frame 1 through the mounting hole 3. A threaded rod 18 is installed at the top of the controller 4. A fixing nut 7 is installed on the outer thread of the threaded rod 18. A control rod 8 is installed at the top of the controller 4, and the bottom end of the control rod 8 passes through the threaded rod 18 and extends to the inside of the controller 4. A fixing hole 2 is provided at the top of the other end of the mounting frame 1. A connecting wire 5 is installed at the bottom of the controller 4, and a wrapping sleeve 6 is installed on the outer side of the connecting wire 5.

[0024] The mounting frame 1 provides a location for installing the controller 4. The controller 4 is installed on the mounting frame 1 so that the controller 4 can be installed on the tricycle for use. The controller 4 fixes the threaded rod 18 at the top through the fixing nut 7 to connect the controller 4 to the mounting frame 1, and then the mounting frame 1 is installed at the location where it is required to be used by using bolts to penetrate the fixing hole 2. The controller 4 is connected to the circuit controlling the hydraulic cylinder through the connecting line 5 so that the controller 4 can control the use of the hydraulic cylinder. The wrapping sleeve 6 is used to limit the connecting line 5. The control rod 8 can move up and down at the top of the controller 4. When the hydraulic cylinder on the tricycle dump box is lifted to a safe use angle, it will touch the control rod 8 to apply pressure to the control rod 8, and the control rod 8 moves toward the inside of the controller 4. The control rod 8 is the switch of the controller 4, so that the hydraulic cylinder automatically stops cutting off the power to avoid damage to the hydraulic cylinder due to untimely cutting off of the power.

[0025] See also Figure 3 , an embodiment provided by the utility model: a three-wheeled vehicle dump bucket limiting structure;

[0026] It includes a mounting groove 9 and a moving rod 10. The bottom end of the control rod 8 is provided with a mounting groove 9. A telescopic spring 13 is installed on the top inner wall of the mounting groove 9. The moving rod 10 is movably installed inside the mounting groove 9. The bottom end of the moving rod 10 is located below the control rod 8. A connecting plate 12 is installed at the top end of the moving rod 10, and the connecting plate 12 is connected to the bottom end of the telescopic spring 13. A contact head 11 is installed at the bottom end of the moving rod 10.

[0027] The mounting groove 9 provides space for the installation of the moving rod 10. The moving rod 10 can move inside the mounting groove 9. When the control rod 8 moves, the contact head 11 will first contact the internal switch of the controller 4. Since the moving rod 10 is connected to the telescopic spring 13 through the connecting plate 12, the moving rod 10 can move elastically in the mounting groove 9, avoiding direct contact with the internal switch of the controller 4 when the control rod 8 moves downward, thereby preventing damage due to excessive impact force or pressure.

[0028] See also Figure 1 and Figure 4 , an embodiment provided by the utility model: a three-wheeled vehicle dump bucket limiting structure;

[0029] The waterproof component 14 is installed on the top of the controller 4. The waterproof component 14 includes a contact plate 15, a protective cover 16 and a fixed chassis 17. The contact plate 15 is installed on the top of the control rod 8. The protective cover 16 is installed on the bottom of the contact plate 15. The protective cover 16 is located on the outside of the control rod 8. The fixed chassis 17 is installed on the bottom of the protective cover 16, and the fixed chassis 17 is fixed on the top of the mounting frame 1.

[0030] The waterproof component 14 plays a waterproof role, and the contact plate 15 provides a position for installing the protective cover 16. The protective cover 16 covers the top of the controller 4, and the bottom is fixed by a fixed chassis 17, so that the protective cover 16 can protect the top of the controller 4 to prevent rainwater from entering the inside of the controller 4 through the top and causing damage to the controller 4. Since the protective cover 16 is a telescopic corrugated shape, it can be extended and retracted along with the control rod 8 and will not affect the use of the control rod 8.

[0031] Working principle: Before using the three-wheeled vehicle dump bucket limiting structure, you should first check whether there are any problems that affect the use of the three-wheeled vehicle dump bucket limiting structure. First, connect the controller 4 to the mounting frame 1, and then fix the controller 4 on the three-wheeled vehicle through the mounting frame 1 for use. When the hydraulic cylinder on the three-wheeled vehicle dump bucket is lifted to a suitable position, pressure will be applied to the control rod 8, so that the controller 4 controls the hydraulic cylinder to automatically stop and cut off the power, and the waterproof component 14 will waterproof the controller 4 to prevent the controller 4 from being damaged by rain when used on the tricycle.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
