Abstract
The utility model discloses a self-propelled toy boat. The screw rod on the screw propeller is provided with a sealing sleeve of the screw rod which is connected a whole with the shell; two ports of the sleeve of the screw rod can only contain the rotation of the screw rod; the sealing oil is arranged in the chamber of the sleeve of the screw rod.
Description
The design belongs to toy boat, particularly can self-propelled ship, warship or submarine.
Have screw, the self-propelled toy boat of energy, common a kind of structural shortcoming is to leak at the screw rod of screw propeller and hull connection place.
The design's purpose is to propose a kind of screw rod sealing device, the manufacturing of suitable toy boat simple in structure.
The design's content is to install a screw rod sealing shroud on screw rod additional, and sealing shroud connects with the hull one, in the screw rod cover Seal Oil is arranged.Screw rod passes from screw rod cover, stretches out that hull is outer, the tipping screw.Screw rod cover closing in gap, two ends only holds the screw rod rotation.
The design's embodiment is as shown in drawings:
Fig. 1 is the toy boat outside drawing.
Fig. 2 is the design's sealing shroud structural representation.
Screw rod 1, sealing shroud collar extension 2, Seal Oil 3, sealing shroud internal orifice 4, shell 5.
In conjunction with the embodiments the design is specified, screw rod 1 passes in sealing shroud, and sealing shroud collar extension 2 and internal orifice 3 only have the gap that allows the screw rod rotation, filling Seal Oil 3 in the sealing shroud chamber.Sealing shroud connects with shell 5 one.The Seal Oil that the design selects for use is advisable with the grease with the viscosity of not trickling under normal water temperature.The design's structure is very simple, and being used for the toy boat making does not increase difficulty.The processing cost that increases is not high yet, but can solve the problem that screw rod and shell connection place leak.
Claims (1)
1, a kind of toy marine propeller comprises screw rod and blade, it is characterized in that having on the screw rod sealing screw rod cover, and sealing screw rod cover connects with the hull one, in the sealing screw rod cover chamber Seal Oil is arranged, and screw rod cover gap between two ends only holds the screw rod rotation.
