Detailed Implementation
[0020] Example 1
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a helicopter rotor support device includes a vertically arranged upright 1, a base 2 at the lower end of the upright 1, and a fixing seat 3 at the upper end of the upright 1. Straps 4 are fixed to the fixing seat 3. A protective layer 5 is provided on the upper side of the fixing seat 3. Preferably, in this embodiment, the protective layer 5 is a soft cloth layer; the soft cloth layer can effectively prevent wear between the rotor and the fixing seat 3 during use, providing effective protection for the surface of the rotor. The upright 1 is an adjustable telescopic rod, which facilitates the storage and transportation of the support device, resulting in low transportation costs. The telescopic rod structure is not an innovation of this embodiment; any telescopic rod structure in the prior art can be used in this application, and will not be described in detail here.
[0022] Both ends of the strap 4 are fixed to both ends of the fixing base 3. Specifically, a mounting part 6 is fixed to the lower side of the fixing base 3, and the mounting part 6 is machined with external threads. Both ends of the strap 4 are provided with connecting holes, and the ends of the strap 4 are fixed to the mounting part 6 of the fixing base 3 through the connecting holes 7 and nuts. In this embodiment, preferably, the strap 4 is a flat braided rope.
[0023] In use, first attach the straps 4 of the support device to the helicopter rotor, then adjust the support pole 1 to the appropriate length and place the base on the ground. In strong winds, it can effectively prevent excessive up-and-down vibration of the helicopter rotor, providing effective protection for the wings; it can also prevent damage caused by accidental rotation of the helicopter rotor.
[0024] Example 2
[0025] like Figure 6 , Figure 7 and Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the upright 1 includes an inner rod 8 and an outer rod 9 fitted outside the inner rod 8, and the inner rod 8 can slide within the outer rod 9. A telescopic control unit is provided between the inner rod 8 and the outer rod 9. The telescopic control unit includes a vertically arranged rack 10 and a fixing part 11 fixed to the upper end of the outer rod 9; the upper end of the rack 10 is fixed to the inner rod 8.
[0026] like Figure 6 , Figure 7 and Figure 8 As shown in the figure, in this preferred embodiment, the fixing part 11 is annular and is fitted onto the outer rod 9; the fixing part 11 has a through notch 12 extending vertically, through which the rack 10 passes; a handle 13 is hinged to the fixing part 11 at the corresponding notch 12. The upper end of the handle 13 has a meshing tooth 14 that matches the rack 10. The number of meshing teeth 14 is preferably two to four. In this preferred embodiment, the number of meshing teeth 14 is three.
[0027] Both sides of the handle 13 are provided with limiting grooves 15, and the fixing part 11 is machined with a receiving cavity 16 corresponding to the position of the limiting groove 15; a positioning ball 17 and a compression spring 18 are installed in sequence in the receiving cavity 16. One end of the receiving cavity 16 is provided with a through hole 19, and the other end is provided with a plug 20; the diameter of the through hole 19 is smaller than the diameter of the positioning ball 17. Under the elastic force of the compression spring 18, part of the positioning ball 17 can extend through the through hole 19 into the limiting groove 15 outside the receiving cavity 16 and achieve the limiting of the handle 13.
[0028] When in use, rotating the handle 13 controls whether the rack 10 and the meshing teeth 14 are engaged or disengaged. When the rack 10 and the meshing teeth 14 are disengaged, the inner rod 8 can slide within the outer rod 9, allowing adjustment of the length of the upright 1. When the rack 10 and the meshing teeth 14 are engaged, they are locked together and cannot slide relative to each other, thus locking the length of the upright 1.
[0029] In summary, this utility model provides a helicopter rotor support device that can effectively prevent excessive vertical vibration of the helicopter rotor during strong winds. It also has the advantages of simple structure, easy installation, and effective protection for the helicopter rotor.
[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
