Abstract

The utility model discloses an aircraft protection ring. The aircraft protection ring comprises a large ring body and a small ring body. The small ring body and the large ring body are concentrically arranged. The small ring body is disposed under the large ring body. The outer wall of the small ring body is provided with radial connecting rods. Extending ends of the radial connecting rods horizontally extend and then are bent upwardly to be connected at the large ring body. The aircraft protection ring has following beneficial effects: the aircraft protection ring has ingenious and reasonable structural design in that a protection structure is formed in such a manner that a propeller is completely covered by the large ring body because the small ring body and the propeller of the aircraft are concentrically arranged; the propeller rotating at high speed is effectively prevented from being damaged when a toy aircraft flies by remote control and people or objects are protected from being hurt by the propeller so that high safety performance is obtained; players do not need to worry that the propeller may be damaged and people or objects may get hurt; playing methods are greatly enriched; much more enjoyment is provided for players; interest and playability are remarkably enhanced; and the aircraft protection ring is advantaged by being simple and compact in integral structure, simple and convenient in assembly, easy in realization and low in cost and is favorable to wide popularization.

Description

Aircraft guard circle

Technical field

The utility model relates to toy technique field, is specifically related to a kind of aircraft guard circle.

Background technology

Toy aircraft is a kind of toy that children and numerous airplane hobbyists like, by wireless control system, aircraft is sent to instruction to realize the landing of aircraft, acceleration and deceleration and direction control etc.

At present, in many toy aircraft, due to the setting of safety guard, make the screw of toy aircraft High Rotation Speed in the time shaking control flight often hurt people; also damage screw; when serious, even cause casualty accident, cause it recreational low, also lack corresponding enjoyment.

Utility model content

For above-mentioned deficiency, the purpose of this utility model is, provides a kind of structural design ingenious, reasonable, can effectively not protect screw damaged and avoid occurring that screw hurts the aircraft guard circle of people or thing.

For achieving the above object, technical scheme provided by the utility model is:

A kind of aircraft guard circle; it comprises large circle body and little circle body; this little circle body and described large circle body concentric arrange; and be positioned at this large circle body under position; the outer wall of this little circle body is evenly provided with multiple radially connecting rods that extend along its radial direction; this radially the elongated end of connecting rod extend horizontally to the lower position of nearly described large circle body, then upwards bending is connected on this large circle body.

As a kind of improvement of the present utility model, the quantity of described radially connecting rod is three, and it is the center of circle and is arranged on symmetrically and evenly on described little circle body.

As a kind of improvement of the present utility model, described little circle body is provided with an opening.

As a kind of improvement of the present utility model, on described little circle body, be at least provided with an installing hole, on the inner ring position of this little circle body, be at least provided with locating notch.

As a kind of improvement of the present utility model, the angle that described radially connecting rod upwards bends is 128～135 degree.

As a kind of improvement of the present utility model, the bottom surface periphery of described large circle body bends inwards and forms one and be used for the bending joint portion being connected with described radially connecting rod.

The beneficial effects of the utility model are: the utility model structural design is ingenious, rationally, screw concentric by little circle body and aircraft arranges, great circle physical efficiency is covered screw completely, form safeguard structure, can effectively make toy aircraft not damaged and avoid occurring that screw hurts the phenomenon of people or thing at the screw that shakes when flight control High Rotation Speed, security performance is high, allow player damage screw and to hurt people or thing without considering, greatly enrich playing method, for player provides more enjoyment, interest and playability are greatly strengthened, avoid player to produce sensation dry as dust, overall structure is simple in addition, compact, parts are few, make assembling more simple and convenient, be easy to realize, production cost is low, be beneficial to extensive popularization.

Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.

Accompanying drawing explanation

Fig. 1 is perspective view of the present utility model.

Fig. 2 is the side-looking structural representation of Fig. 1.

Structural representation when Fig. 3 is the utility model use.

The specific embodiment

Referring to Fig. 1 to Fig. 3; a kind of aircraft guard circle that the present embodiment provides; it comprises large circle body 1 and ringlet body 2; this ringlet body 2 and described large circle body 1 concentric setting; and be positioned at this large circle body 1 under position; the outer wall of this ringlet body 2 is evenly provided with multiple radially connecting rods 3 that extend along its radial direction, this radially the elongated end of connecting rod 3 extend horizontally to the lower position of nearly described large circle body 1, then upwards bending is connected on this large circle body 1.The angle that described radially connecting rod 3 upwards bends is preferably 128～135 degree.

Described ringlet body 2 is provided with an opening 21.Fast and easy and aircraft 4 are suitable, just can install without dismounting screw 41, easy for installation, quick.

In the present embodiment, the quantity of described radially connecting rod 3 is three, and it is the center of circle and is arranged on symmetrically and evenly on described ringlet body 2.In other embodiment, can carry out the corresponding radially quantity of connecting rod 3 of establishing according to required protection intensity effect or modeling effect, as four, five, eight etc.

In the present embodiment, on described ringlet body 2, be at least provided with an installing hole 22, on the inner ring position of this ringlet body 2, be at least provided with locating notch 23.Coordinate stable, firm, in other embodiment, also can adopt buckle or connected mode is assembled with glue is bonding etc., can also on ringlet body 2, be provided with two installing holes 22, and without be provided with again locating notch 23 on the inner ring position of this ringlet body 2, can certainly be provided with locating notch 23, fast and easy location like this, and then promote efficiency of assembling.

The bottom surface periphery of described large circle body 1 bends inwards and forms one and be used for the bending joint portion 11 being connected with described radially connecting rod 3.Be connected firmly, structural stability is good, effectively promotes impact resistance.

When assembling, first, by the just rotating shaft to screw 41 of the opening on ringlet body 2 21, then align assembling, make ringlet body 2 and screw 41 concentric settings, then locate on the housing that is fixed on aircraft 4 by screw.At this moment, the large circle body 1 that is positioned at ringlet body 2 tops can cover screw 41 completely, form safeguard structure, can effectively make aircraft 4 not damaged and avoid occurring that screw 41 hurts the phenomenon of people or thing at the screw 41 that shakes when flight control High Rotation Speed, security performance is high, allow player damage screw 41 and to hurt people or thing without considering, greatly enrich playing method, for player provides more enjoyment, greatly strengthen interest and playability, avoided player to produce sensation dry as dust.

In addition, when player is played certain familiarity, also aircraft guard circle can be pulled down, there is detachable function, meet the different demands of playing.

As described in the utility model above-described embodiment, adopt structure same or analogous with it and the guard circle of other toy of obtaining, all in the utility model protection domain.
