Specific embodiment
The utility model is further elaborated and illustrated with reference to specific embodiment and Figure of description:
It please refers to Fig.1 and Fig. 2, a kind of frame for baby cart, including main-beam pipe 20, back breeches pipe 10, elastic cushion block 40 and locking member,
The elastic cushion block 40 is silica gel, and described 20 one end of main-beam pipe is equipped with front tube 80, and the other end is equipped with preceding folding joint 31, before described
The one side of folding joint 31 is equipped with the first hinged ear 311, and 31 middle part of preceding folding joint is equipped with the first locking hole 312, and described first
Locking hole 312 is screw hole, and the preceding folding joint 31 is welded to connect on main-beam pipe 20, in being additionally provided on the main-beam pipe 20
Pipe 60, one end of the back breeches pipe 10 are equipped with rear folding joint 32, and the one side of the rear folding joint 32 is equipped with the second hinged ear
321 are equipped with insertion groove with insertion column 322, the back breeches pipe 10, and the insertion column 322 of the rear folding joint 32 is arranged on back breeches pipe
In 10 insertion groove, the middle part of rear folding joint 32 is equipped with the second locking hole, and the rear folding joint 32 is welded to connect in back vent
On pipe 10, the insertion column 322 on rear folding joint 32 can improve back breeches pipe 10 and the bonding strength after the welding of rear folding joint 32,
The first hinged ear 311 on the preceding folding joint 31 is hinged with the second hinged ear 321 on rear folding joint 32 by hinge shaft
Connection, the elastic cushion block 40 are arranged between preceding folding joint 31 and rear folding joint 32, and the locking member is screw 70.
It please refers to Fig.3, the elastic cushion block 40 is equipped with the first binding face and the second binding face, and first binding face is with before
One end end face fitting of folding joint 31, second binding face are bonded with one end end face of rear folding joint 32, and described first
Angle between binding face and the second binding face is 15 ° to 45 °, and the elastic cushion block 40 is equipped with through hole 41, the through hole 41
Through the first binding face and the second binding face, second binding face is equipped with location hole 42, is set on the rear folding joint 32
There is positioning column, the location hole and positioning column correspond to, and the elastic cushion block 40 is rolled over after being fitted in by location hole 42 and positioning column
Splice first 32 one end end face, the screw 70 is through the second locking hole, logical on elastic cushion block 40 on rear folding joint 32
The first locking hole 312 on Kong Yuqian folding joints 31 is locked.
Light-weight due to children, during riding, elastic cushion block 40 can generate certain elastic deformation, have and subtract
The effect of shake, and because the one side of preceding folding joint and the one side of rear folding joint are articulated and connected, amplitude occurs in elastic cushion block 40
During little elastic deformation, riding safety can guarantee.Angle between first binding face and the second binding face is 15 ° to 45 °, is subtracted
Shake effect is good and preceding folding joint is connected reliably with rear folding joint.
In said program, preceding folding joint and rear folding joint can also be locked by bolts and nuts.
It, can be preceding by being equipped with location hole on first binding face to prevent elastic cushion block 40 from shifting in said program
Positioning column is set on folding joint, location hole and positioning column correspond to, before the elastic cushion block is fitted in by location hole and positioning column
One end end face of folding joint.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this reality
With the limitation of novel protected scope, although being explained in detail with reference to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
