Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
With reference to Fig. 1~Fig. 5, a kind of Undercarriage structure for hand buggy is described including the undersetting 19 being mounted on vehicle frame
Undercarriage structure includes preceding bottom girder and rear bottom girder, and the rear end of the preceding bottom girder and the front end of bottom girder afterwards may be reversed 90 degree and be hinged；
The preceding bottom girder and rear bottom girder are respectively U-shaped, and overturning seat 18 is respectively equipped on the rear end of the preceding bottom girder and the front end of rear bottom girder,
Two overturning seats 18 are hinged by articulated shaft；The front end of the preceding bottom girder is hinged with the undersetting on vehicle frame side arm, the rear bottom
The rear end of beam is hinged with the undersetting on vehicle frame after-frame.
Further, the undersetting 19 is equipped with the side frame connecting portion that is connected with side frame and is connected with vehicle frame side arm or after-frame
Front and rear frame connecting portion, the front end of the preceding bottom girder are located at the side frame connecting portion of the undersetting on vehicle frame side arm and front and rear frame connecting portion
Between and be hinged on the side frame connecting portion of corresponding undersetting, it is described after the rear end of bottom girder be located at undersetting on vehicle frame after-frame
Side frame connecting portion and front and rear frame connecting portion between and be hinged on the side frame connecting portion of corresponding undersetting.
In the present embodiment, bottom girder 17 includes preceding bottom girder and rear bottom girder.
The course of work of the utility model is：Chassis will be fixed on respectively by two bottom girders 17 head to head by articulated shaft
Two overturning seats 18 thereon connect；Simultaneously two foundation beams 17 four angles respectively with rivet fix on undersetting 19.
During folding, lift overturning seat 18 vertically upwards, collapse articulated shaft axle center rotation of the bottom girder 17 on overturning seat 18, drive simultaneously
The folding together of undersetting 19, until two undersettings 19 with side are put off till together.During opening, it is pressed downward, by overturning seat 18, making two
A bottom girder 17 is strutted to both sides, until rear /V is arrived on two overturning seats 18 mutually top.When chassis is pressurized, due to two overturning seats 18
Mutually spacing top is after death linked to be entirety downwards, while four angles of two bottom girders 17 are riveted on the side frame of four lower carriages 19 respectively
Between connecting portion and front and rear frame connecting portion, so as to further improve the bearing capacity of chassis.
