Abstract

The invention relates to a connection device for a tail rotor of a helicopter model. The connection device for the tail rotor of the helicopter model comprises a rotor main body, a rotary device is arranged at the lower end of the rotor main body, a rotary shaft is actively connected to the rotary device, the upper end of the rotary shaft is fixedly connected with the rotor main body, a connection device is sleeved outside the rotary device, a notch is formed at the opening end at the upper end of the connection device, and the connection device and the rotary device can be conveniently connected through the notch, the side wall of the connection device is fixedly connected with a connection cylinder being corresponding to the tail girder of the helicopter, the outer side wall of the connection cylinder is opened with a through hole used for fixing the tail girder in the connection cylinder through the bolt. The connection device for the tail rotor of the helicopter model has split type connection to the tail girder for preventing abrasion of the tail girder for rotary of the rotor, the later period maintenance cost can be reduced and the service life of the tail girder can be greatly prolonged.

Description

A kind of attachment means for helicopter model tail undercarriage
Technical field
The present invention relates to a kind of attachment means for helicopter model tail undercarriage.
Background technology
Common helicopter model tail undercarriage is connected directly between on tail boom more, not only dismantles trouble, and for a long time It is easy to after use tail boom is worn and torn, causes whole tail boom to damage, thus cause whole model to be scrapped, maintenance and replacement cost The highest.
Summary of the invention
The technical problem to be solved in the present invention is: for the problem solving above-mentioned existence, it is provided that a kind of for helicopter model The attachment means of tail undercarriage, solves pure helicopter tail undercarriage dismounting trouble and the problem of the tail boom that easily weares and teares.
The technical solution adopted for the present invention to solve the technical problems is: a kind of for helicopter model tail undercarriage Attachment means, including propeller body, propeller body lower end is provided with rotary apparatus, rotary apparatus is connected with and turns Axle, rotating shaft upper end is fixing with propeller body to be connected, and rotary apparatus is cased with attachment means, and attachment means upper end open end is arranged Have the gap for facilitating rotary apparatus to be connected with attachment means, attachment means sidewall is fixedly connected with for go straight up to tail The connecting cylinder that beam is corresponding, connecting cylinder lateral wall offers for tail boom is bolted to the through hole within connecting cylinder.
Further, attachment means outer surface has three reinforcements.
Further, attachment means is internally provided with skid resistant course.
The invention has the beneficial effects as follows, the present invention for helicopter model tail undercarriage attachment means by with tail The split type connection of beam, thus prevent propeller from rotating abrasion tail boom, reduce later maintenance cost and be greatly prolonged the use of tail boom Life-span.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the decomposition texture schematic diagram of the present invention.
Fig. 2 is the structural representation of the present invention.
1. propeller body, 2. rotary apparatus, 3. rotating shaft, 4. attachment means, 5. gap, 6. connecting cylinder, 7. through hole in figure, 8. reinforcement.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only with The basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
A kind of attachment means for helicopter model tail undercarriage as depicted in figs. 1 and 2, including propeller body 1, propeller body 1 lower end is provided with rotary apparatus 2, and rotary apparatus 2 is connected with rotating shaft 3, rotating shaft 3 upper end and propeller Body 1 is fixing to be connected, and rotary apparatus 2 is cased with attachment means 4, and attachment means 4 upper end open end is provided with and rotates for convenient The gap 5 that device 2 is connected with attachment means 4, attachment means 4 sidewall is fixedly connected with for the company corresponding with tail boom Connecing cylinder 6, connecting cylinder 6 lateral wall offering for tail boom being bolted to the through hole 7 within connecting cylinder 6, further, even Connection device 4 outer surface has three reinforcements 8, and further, attachment means 4 is internally provided with skid resistant course, and the present invention is used for The attachment means of helicopter model tail undercarriage is connected by split type with tail boom, thus prevents propeller from rotating abrasion tail Beam, reduces later maintenance cost and is greatly prolonged the service life of tail boom.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff is complete Entirely can carry out various change and amendment in the range of without departing from this invention technological thought.The technology of this invention The content that property scope is not limited in description, it is necessary to determine its technical scope according to right.
