Abstract
The utility model is a kind of tricycle car body extensible canopy, including outer beam, inner beam is socketed with the longitudinal direction in the outer beam, the Wai Liang is consistent with interior beam length and is in square tube shape, the outer beam is stretched out in one end of the inner beam, the outer beam is respectively equipped with multiple roller bearings on four sides of length direction, and the axle of the roller bearing is fixed on the inwall of the outer beam, and the roller of the roller bearing is rolled on the outer wall of the inner beam.
Description
Technical field
It the utility model is related to tricycle bicycle beam field, more particularly to a kind of tricycle car body extensible canopy.
Background technology
Tricycle is the vehicles that a kind of bicycle transformation forms, and can also be freighted with manned, in the 1930s
It is later very popular, it then progressively instead of the status of rickshaw.
Tricycle is divided into former and later two parts, and there are a wheel that can be turned to, handlebar, bicycle bell, brake, pedal in front portion
And vehicle seat, with the vehicle wheel rotation at chain-driving rear portion.Tricycle rear portion is mainly compartment, and carriage body is wooden semicircle, can be simultaneously
Row takes two people.The awning that can be folded is installed on compartment, spring and two wheels are housed below.It is one below seat
Individual wooden case, it can open, instrument debris of the inside storage driver etc..The cushion that useful cloth and cotton-wool are made on seat, lower section has
Pedal.Two see hook before compartment, can hang rain-proof door curtain, and door curtain is typically made with canvas or oilcloth, and winter then uses cotton door instead
Curtain, keep out the wind and go to a winter resort.
Tricycle seat is increased and shortened, and is typically designed a kind of telescopic component, but traditional telescopic component persistence
Difference, negative G is poor, is easily deformed, flexible ability, therefore, designing a kind of tricycle car body extensible canopy, solves problem above.
The content of the invention
The utility model is overcomes the above insufficient, there is provided a kind of tricycle car body extensible canopy, including outer beam, in the outer beam
Inner beam is socketed with the longitudinal direction, and the Wai Liang is consistent with interior beam length and is in square tube shape, and one end of the inner beam is stretched out
The outer beam, the outer beam are respectively equipped with multiple roller bearings on four sides of length direction, and the roller bearing
Axle is fixed on the inwall of the outer beam, and the roller of the roller bearing is rolled on the outer wall of the inner beam.
Further, the roller bearing is embedded in the side wall of the outer beam.
Preferably, the material of the outer beam and inner beam is steel.
The beneficial effects of the utility model are：
A kind of tricycle car body extensible canopy described in the utility model, easy to use, precision is high, and heavy burden ability is strong, durable
Property is strong, capable of expansion and contraction.
Brief description of the drawings
Fig. 1 is a kind of cross section structure schematic diagram of tricycle car body extensible canopy described in the utility model；
Wherein：1- inner beams；2- roller bearings；The outer beams of 3-.
Embodiment
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
As shown in figure 1, a kind of tricycle car body extensible canopy, including outer beam 3, it is socketed in the longitudinal direction in the outer beam 3
There is inner beam 1, the outer beam 3 is consistent with the length of inner beam 1 and is in square tube shape, and the outer beam 3, institute are stretched out in one end of the inner beam 1
State outer beam 3 and be respectively equipped with multiple roller bearings 2 on four sides of length direction, and the axle of the roller bearing 2 is fixed on
On the inwall of the outer beam 3, and the roller of the roller bearing 2 is set to be rolled on the outer wall of the inner beam 1.
Further, the roller bearing 2 is embedded in the side wall of the outer beam 3.
Preferably, the material of the outer beam 3 and inner beam 1 is steel.
Application method：
In use, a kind of tricycle car body extensible canopy described in Fig. 1 is turned clockwise 90 °, during Fig. 1 states, vehicle seat is solid
It is scheduled on the left side of the inner beam 1, it is possible to achieve upper and lower telescopic adjustment.
Described inner beam 1, outer beam 3 and roller bearing 2 is all steel construction.The inner beam 1 and outer beam 3 of square add heavy burden energy
Power and it is resistance to firmly.
The extensible canopy of tricycle car body is board-like drawing and pulling type, the pattern of drawer-like, heavy burden ability, and its appearance by someone
Fragile, improved tricycle car body extensible canopy uses linear bearing, as the part of rolling, but the material of linear bearing inner sleeve
Matter is mostly plastic material, heavy burden ability, and is extremely easily damaged, and linear bearing is changed after damage, causes the increase of cost,
Inconvenience is brought, but roller bearing 2 is pure steel construction, it is durable and durable.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
