Abstract
The utility model discloses a multifunctional rotating vehicle ladder, wherein three surfaces of the vehicle ladder are connected into a whole; the vehicle ladder has simple structure, is novel and unique, is convenient for adjustment and is multifunctional; the rotating and positioning functions of the entire vehicle ladder can be cushily finished by simple operation through a user; and the vehicle ladder can be used as the vehicle ladder of various travel tools, and thoroughly changes the structure and the use mode of the traditional vehicle ladder.
Description
Technical field
The utility model relates to a kind of multifunctional rotary ladder of changing trains or buses, the car ladder that particularly a kind of novelty is unique, simple in structure, easy to adjust, a ladder is used more, its needs user carries out shirtsleeve operation, just can finish the function of whole car ladder positioning of rotating very like a cork, can be used as the car ladder of multiple walking-replacing tool, thoroughly change the structure and the occupation mode of traditional vehicle ladder.
Background technology
The small-wheel bicycle of Xiao Shouing, toy car are not provided with the car ladder basically in the market, individual other is provided with and also mostly is the bicycle ladder, it has simple supporting role, run into the external force effect slightly, be easy to rollover, and little, light, the skilful feature that BMX (Bicycle Motocross) itself has has determined that the car ladder is multi-functional, and higher to its stability requirement, can not fully satisfy the demand of various on the market walking-replacing tools to safe and practical car ladder at all.
Summary of the invention
Technical problem to be solved in the utility model is: the car ladder that a kind of novelty is unique, simple in structure, easy to adjust, a ladder is used more is provided, its needs user carries out shirtsleeve operation, just can finish the function of whole car ladder positioning of rotating very like a cork, can be used as the car ladder of multiple walking-replacing tool, thoroughly change the structure and the occupation mode of traditional vehicle ladder.
The technical scheme that the utility model adopted is: a kind of multifunctional rotary ladder of changing trains or buses, it is three car ladders that connect one.
Described car ladder downside is a cambered surface thin-walled cover plate, and the center of circle of its cambered surface is the axle center of wheel, and radius is greater than the radius of wheel.
The main body frame of described car ladder both sides is the both sides height, and is middle low, makes the car ladder vertically prop up ground, and direct contact ground, both sides is middle unsettled.
Described car ladder pivots to upside, can be used as the mudwing of wheel.
Described biside plate axis hole periphery has knock hole, knock hole is the smaller part circular hole, the face that contacts with car ladder biside plate also has knock hole, stage clip and ball are arranged in it, the application force of stage clip make steel ball constantly and car ladder biside plate medial surface fit, the knock hole of car ladder medial surface and with face that car ladder biside plate contact on stage clip in the hole and the ball angle that can regulate the terraced positioning of rotating of car.
Under initial condition, the car ladder is in wheel top; the cambered surface of thin-walled cover plate is upwards; this moment, user's application of force overcame the effect friction force of steel ball and stage clip, makes the car ladder be rotated down; steel ball is positioned in the knock hole of car ladder just as the mudwing of wheel; this moment, the car ladder was built on stilts wheel, play a supporting role, and thin-walled cover plate direct contact ground not.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein:
1: thin-walled cover plate 2: main body frame
3: axle 4: knock hole
The specific embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify the multifunctional rotary of the present utility model ladder of changing trains or buses.
As shown in the figure, the multifunctional rotary of the present utility model ladder of changing trains or buses, it is three car ladders that connect one.
Described car ladder downside is a cambered surface thin-walled cover plate 1, and the center of circle of its cambered surface is the axle center of wheel, and radius is greater than the radius of wheel.
The main body frame 2 of described car ladder both sides is the both sides height, and is middle low, makes the car ladder vertically prop up ground, and direct contact ground, both sides is middle unsettled.
Described car ladder rotates to upside around axle 3, can be used as the mudwing of wheel.
Described biside plate axis hole periphery has knock hole 4, knock hole is the smaller part circular hole, the face that contacts with car ladder biside plate also has knock hole, stage clip and ball are arranged in it, the application force of stage clip make steel ball constantly and car ladder biside plate medial surface fit, the knock hole of car ladder medial surface and with face that car ladder biside plate contact on stage clip in the hole and the ball angle that can regulate the terraced positioning of rotating of car.
Under initial condition, the car ladder is in wheel top; the cambered surface of thin-walled cover plate 1 is upwards; this moment, user's application of force overcame the effect friction force of steel ball and stage clip, makes the car ladder be rotated down around axle 3; steel ball is positioned in the knock hole 4 of car ladder just as the mudwing of wheel; this moment, the car ladder was built on stilts wheel, play a supporting role, and thin-walled cover plate 1 direct contact ground not.
