Abstract
The utility model discloses a toy helicopter which comprises a fuselage body and a propeller group that consists of two dismountable blades, wherein, one blade is provided with a fastener while the other blade is provided with a bolt that can be cuttage-grafted and jammed with the fastener. The propeller group of the toy helicopter of the utility model is formed by cuttage grafting the two dismountable blades, and the blades can be replaced when being broken, and only the blades are needed to be replaced to recover the playing value when other parts of the fuselage are not damaged, and no waste can be caused; a main axis and the blades of the propeller can be manufactured and assembled respectively, and the manufacture difficulty and the production cost can be reduced greatly.
Description
Technical field
The utility model relates to a kind of toy, particularly a kind of electronic toy helicopter.
Background technology
Along with expanding economy, the kind of toy is more and more, and more and more professional, especially toy helicopter, by adopting the mode of two groups of screws, improve its flight stability greatly, flying distance is also more and more far away, and also available remote controller is controlled the flying speed and the heading of aircraft, increase the entertaining of playing, be subjected to liking of child deeply, open as on December 20th, 2006, publication number is the Chinese utility model patent of CN 2748313Y.But the left and right sides blade of existing every group of screw of toy helicopter all is fixedly connected being integral, and rotor shaft is fixed in the perforation that left and right sides blade pass is crossed middle interconnecting piece, and with the integrated spindle axis moulding, can't separate.Because the blade of screw is generally made by frivolous plastic sheet, in fast rotational, fracture easily, and the left and right sides blade and the integrated spindle axis moulding of existing screw, can't change separately behind the blade broken, even miscellaneous part is intact, helicopter also can't fly owing to lack blade, lose the meaning of playing, cause the waste of other parts, and blade and integrated spindle axis moulding make that also manufacture difficulty is big, loss is big in production cost height and the transportation.
Summary of the invention
At above-mentioned defective, the utility model provides a kind of left and right sides blade of screw group detachable, the toy helicopter that manufacture difficulty and production cost are low.
A kind of toy helicopter of the present utility model comprises fuselage body and screw group thereof, it is characterized in that: described every group of screw is made of two detachable blades, and wherein a blade is provided with fastener, and the plug of fastener can be pegged graft and block to another blade setting.
Described fastener is the through hole of being located on the blade inserted terminal, and this through hole has for the inlet of plug insertion and the outlet of jam plug.
Described plug is made of the two parallel grafting thin slices that axially stretch out along the blade inserted terminal, and described grafting thin slice end is protruding for the inclination card that can run through and block the fastener outlet.
The inserted terminal of described each blade is provided with fastener and plug simultaneously.
The inserted terminal of described two blades is respectively equipped with and is socketed on the sleeve joint hole of rotor shaft with fixed blade.
Toy helicopter of the present utility model, its screw group is pegged graft by two blades about detachable and is formed, be at play or transportation in can change separately behind the blade broken, following of the situation of not damaging to need to change blade at other parts of fuselage body so just can recover play value, can not cause the waste of other parts; Assemble again after also making its rotor shaft and blade can make moulding respectively, reduce manufacture difficulty and production cost greatly.

The specific embodiment
As shown in Figure 1, the utility model comprises fuselage body and is located at screw group 1 on the fuselage body, and screw group 1 is made of two detachable blades 11, and wherein a blade is provided with fastener 2, and the plug 3 of fastener 2 can be pegged graft and block to another blade setting.Fastener 2 is for being located at the through hole on blade 11 inserted terminals 4, and this through hole is provided with for the inlet 21 of plug 3 insertions and the outlet 22 of jam plug.Plug 3 is made of the two parallel grafting thin slices 31 that axially stretch out along blade inserted terminal 4, and grafting thin slice 31 is made by flexiplast, and during insertion, the constraint of fastener 2 is drawn close and entered easily to the centre.Grafting thin slice 31 ends be provided with the inclination that after running through fastener outlet 22, can block outlet 22 block protruding 32, tilt card protruding 32 with export 22 cooperate can with about two blades fastening.
More fastening for two blades grafting about making, the inserted terminal 4 of two blades 11 all is provided with fastener and plug simultaneously, and in this enforcement, every blade is equipped with a fastener and a plug.
Corresponding every group of screw is provided with two projectioies on the rotor shaft of the present utility model, and inserted terminal 4 correspondences of blade 11 are provided with and are socketed on this projection with the sleeve joint hole 5 of vanes fixed on main shaft.During assembling, with sleeve joint hole 5 alignment bumps, plug 3 aim at fasteners 2 insert just can, simple and convenient.
Claims (5)
