The utility model content
The purpose of this utility model provides a kind of electric vehicle rack wheel, and this rack wheel can make the rider easily battery-driven car be pushed away away after battery-driven car is blown out.
For achieving the above object, the utility model adopts following technical scheme:
The electric vehicle rack wheel that the utility model provides, this rack wheel is fixed on the axletree of battery-driven car, described rack wheel comprises sleeve pipe, be socketed in the loop bar in the sleeve pipe and be arranged on the small wheels of loop bar lower end, and the upper end of described sleeve pipe is connected with the axletree of battery-driven car; The upper and lower of described sleeve pipe offers screw respectively, and the top and the bottom of described loop bar offer and the corresponding screw of sleeve pipe screw, and screw on this sleeve pipe and the screw on the loop bar are fixed together by screw rod.
Further, the upper end of described sleeve pipe has extended to form connecting portion to a side, and this connecting portion offers screw away from an end of sleeve pipe.
Wherein, after the screw on described sleeve pipe top and the screw of loop bar were fixed together by screw rod, the height of described sleeve pipe upper end wheel face to the small wheels was less than the radius of battery-driven car wheel; After the screw of described sleeve pipe bottom and the screw of loop bar were fixed together by screw rod, the height of described sleeve pipe upper end wheel face to the small wheels was greater than the radius of battery-driven car wheel.
The electric vehicle rack wheel that the utility model provides, be installed in the both sides of battery-driven car front and back wheel wheel shaft, when the battery-driven car cruising, the screw on sleeve pipe top captiveed joint with the screw of loop bar, loop bar is contracted in the inside of sleeve pipe, and rack wheel does not influence the operation of battery-driven car; After battery-driven car is blown out, the screw of sleeve pipe bottom to be captiveed joint with the screw of loop bar, loop bar stretches out sleeve pipe, and the small wheels of loop bar lower end supports on the ground, makes things convenient for the rider that battery-driven car is pushed away away.
Description of drawings
Fig. 1 is the structural representation that the utility model two is taken turns the electric vehicle rack wheel;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the stand-by state scheme drawing that the utility model two is taken turns the electric vehicle rack wheel;
Fig. 4 is the working state schematic representation that the utility model two is taken turns the electric vehicle rack wheel.
The specific embodiment
In order to make those skilled in the art person understand the utility model scheme better, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the embodiment of the electric vehicle rack wheel that the utility model provides, during use, this rack wheel 10 is fixed on the axletree of battery-driven car; Described rack wheel 10 comprises sleeve pipe 11, be socketed in the loop bar 12 in the sleeve pipe 11 and be arranged on the small wheels 13 of loop bar 12 lower ends, and the upper end of described sleeve pipe 11 is connected with the axletree of battery-driven car; The upper and lower of described sleeve pipe 11 offers screw 111,112 respectively, the top of described loop bar 12 offers and sleeve pipe 11 screws 111,112 corresponding screws 121, and the screw 111,112 on this sleeve pipe 11 and the screw on the loop bar 12 121 are fixed by screw rod.Sleeve pipe 11 makes rack wheel 10 have standby and two states of work by the connection location of screw 111 and screw 112 and two gears of loop bar 12 formation.
As shown in Figure 3, Figure 4, after the screw 121 of the screw on described sleeve pipe 11 tops 111 and loop bar 12 was fixed together by screw rod, described sleeve pipe 11 upper ends were to the height of 13 times wheel faces of the small wheels radius less than battery-driven car wheel 20; Make rack wheel 10 be in stand-by state, do not influence the cruising of battery-driven car.After the screw 112 of described sleeve pipe 11 bottoms was fixed together by screw rod with the screw 121 of loop bar 12, described sleeve pipe 11 upper ends were to the height of 13 times wheel faces of the small wheels radius greater than battery-driven car wheel 20; Make rack wheel 10 in running order, make things convenient for the rider that battery-driven car is pushed away away.
The upper end of described sleeve pipe 11 has extended to form connecting portion 15 to a side, and this connecting portion 15 offers screw away from an end of sleeve pipe 11, is used for connecting portion 15 spiral shells admittedly at wheel stand, to strengthen the steadiness that rack wheel 10 is installed on battery-driven car.
The electric vehicle rack wheel that the utility model provides, be installed in the both sides of battery-driven car front and back wheel wheel shaft, when the battery-driven car cruising, the screw 111 on sleeve pipe 11 tops is captiveed joint with the screw 121 of loop bar 12, loop bar 12 is contracted in the inside of sleeve pipe 11, and rack wheel does not influence the cruising of battery-driven car; After battery-driven car is blown out, the screw 112 of sleeve pipe 11 bottoms to be captiveed joint with the screw 121 of loop bar 12, loop bar 12 stretches out sleeve pipe 11, and the small wheels 13 of loop bar 12 lower ends supports on the ground, makes things convenient for the rider that battery-driven car is pushed away away.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
