Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a landing gear structure of an aviation helicopter model aircraft, to solve the problem that most of the existing landing gears do not have the function of secondary auxiliary buffering in the process of actual use, and the buffering and shock-absorbing effect is effective. There is room for improvement, and most of them cannot adjust the cushioning and supporting strength according to the hardness of the ground and the weight of the model aircraft itself, resulting in poor applicability

Abstract

The invention provides an undercarriage structure of an aerial helicopter model. The undercarriage structure comprises a spacer ring, double-end locking screws, a main support plate and pulleys; the position of the middle joint of each positioning chute is provided with a solid block, each of left and right sides of the solid block is provided with a rectangular track groove, and left-right arrangement positions of the rectangular track grooves and two X-like arranged support rods are laterally staggered with a certain distance; two slotting holes are formed in the main support plate symmetrically and penetratingly, two sliding support shafts are corresponding inserted in the slotting holes, and each sliding support shaft is sleeved with a buffer spring. By the arrangement of the four pulleys, the pulleys on the supporting rods can slide in a follow-up manner in the four rectangular track grooves formed in the two positioning chutes when the two supporting rods rotate with each other,and the supporting rods can be assured to rotate in the X-like manner and stretch and tighten the springs for normal shock buffering.

Description

technical field [0001] The invention belongs to the technical field of aircraft model landing gear, and more specifically relates to a landing gear structure of an aviation helicopter model aircraft. Background technique [0002] At present, the aeromodelling movement is booming on a large scale, and the aeromodelling technology is becoming more and more mature. However, the research and design of the landing gear of the model airplane helicopter as the parts outside the fuselage of the model airplane helicopter has also been put on the agenda. [0003] After retrieval, for example, the patent No. CN204093041U discloses a model airplane helicopter landing gear, which includes a base for connecting with the fuselage of the airplane model helicopter; a connecting rod group connected with the base, and the connecting rod group is provided with at least three, Each connecting rod group is connected with a shock-absorbing outrigger; and a power generating component is used to ge...
