Abstract

The utility model discloses a handle connection device of small handcraft. Wherein, a locking sleeve tube is fixed on the handcraft frame, and the axes of the sleeve tube is perpendicular to the forward direction of the handcraft; the inserted rod is inserted in the sleeve tube, and the inserted rod and the handle body form a angle. The handle connective device of the small handcraft has the handle in the inserted tube, and the inserted hole is perpendicular to the forward direction of the small handcraft, moreover, the inserted rod can rotate in the sleeve tube and the handle body rotates after the inserted rod; because the angle between the inserted rod and the handle body, the height of the handle body can be adjusted, and the height can be definite after locking sleeve tube, cramping the inserted rod, and fixing the handle; the small handcraft occupies small space if rotating and folding the handle on the small handcraft.

Description

A kind of handle connecting device of waggon

Technical field:

The utility model relates to the handle connecting device of waggon (or towing dolly)

Background technology:

Except that the drawing handle of collapsible parcel car or baggage container is scalable, the handle of general waggon is all fixed, the height of handle is non-adjustable, the same waggon of people's push-and-pull that height is different may someone will feel under the weather, in addition, when waggon did not use, handle was outwards upheld, and took parking space.

The utility model content:

The purpose of this utility model is to provide a kind of hand barrow handle height of adjusting can make the folding waggon handle connecting device of handle again.

Waggon handle connecting device described in the utility model, but the locking sleeve that a pressurized changes internal diameter on vehicle frame, fixed, the axis normal of sleeve pipe is in the working direction of dolly, and the inserted link of handle is inserted in the sleeve pipe, and the inserted link kink constitutes handle.

Waggon handle connecting device described in the utility model, handle is inserted in the sleeve pipe, and jack is perpendicular to the working direction of dolly, inserted link can rotate in sleeve pipe, handle main body is rotated thereupon, because the inserted link kink constitutes handle, so the handle main body adjustable height.After the handle height adjustment was suitable, locking sleeve clamped inserted link, fixed handle, and this can determine that highly when waggon did not use, turning handle made it to close up on dolly, it is little to take parking space.

Description of drawings:

Fig. 1 is a scheme drawing of the present utility model.

The specific embodiment:

As shown in Figure 1, locking sleeve 2 is fixed on the support board 1 (or vehicle frame) of dolly, the axis of sleeve pipe 2 is vertical with the dolly working direction.The inserted link 4 of handle 3 is inserted in the sleeve pipe 2, and inserted link 4 is bent to form handle 3.The handle main body 3 of present embodiment is vertical with inserted link 4, and grip portions 5 is parallel with inserted link.

Locking sleeve is a prior art, there is multiple locking mode available, so preferable mode is to use eccentric handle mechanism, pull bar 6 one ends of this mechanism have boss 7, block an earclip 8 of sleeve pipe, and the other end has eccentric handle 9 to prop up another earclip 10, turning handle, affect pull bar 6, grip sleeve 2 makes it to clamp tightly handle inserted link 4.

Owing to only depend on the rotation of the Clamping force restriction handle of sleeve pipe, less reliable is opened a plurality of grooves 11 at sleeve pipe one end, and the inserted link 4 of handle stretches out sleeve pipe, and there is radial peg 12 can snap in the groove on the external part, when clamping device loosened, handle inserted link 4 can move axially along sleeve pipe, and radial peg 12 snaps in thereupon or withdraw from groove 11, after radial peg 12 withdraws from groove 11, inserted link 4 rotates suitable angle and inserts in another groove again, can adjust the handle height, or with under the folding plant of the handle vehicle frame.
