Abstract

The invention discloses a dolly with adjustable handles. The dolly comprises a frame. A goods carrier is fixed above the frame. Front wheels and rear wheels are mounted below the frame. Handle mounting tubes are formed on the left and right sides of the rear end of the frame. A threaded hole is formed in the upper end of each handle mounting tube. A bolt is inserted in each threaded hole. Each handle is inserted in the corresponding handle mounting tube. Each handle comprises a gripping end and an inserting end. A plurality of annular grooves are formed in the outer surface of each inserting end. A plurality of circular holes are formed in each annular groove. One end of each bolt is inserted in the corresponding circular hole, and a rotary head is fixed at the other end of each bolt. The dolly with the adjustable handles has the advantages that the structures of the handles and the handle mounting tubes are modified, the handles can be flexibly rotated or lifted according to actual needs, the handles can be rotated inwards and fixed to save space during use or storage, the adjusting positions can be found conveniently during adjustment, and the handles are less prone to loosening after being fixed and firm.

Description

A kind of dolly of adjustable handle-bar

technical field:

The present invention relates to transport trolley technical field, relate in particular to a kind of dolly of adjustable handle-bar.

background technology:

Existing dolly is conventionally all fairly simple, particularly in this structure of cart handle, common and vehicle frame is integral type, and this structure in use has limitation, workman cannot regulate according to the height of oneself and the comfort level of exerting oneself, and go-cart is when entering elevator or other finite spaces, often, because handle protrudes from outside go-cart is interfered, uses or puts and need to waste certain space.

summary of the invention:

Object of the present invention is exactly in order to solve existing issue, and provide a kind of dolly of adjustable handle-bar, realized according to the effect of actual requirement flexible rotating or lifting handle, and handle inwardly can be rotated and fixes and saving space when use or placement, when regulating, can conveniently find and adjust position, after fixing, be difficult for loosening, very firm.

Technology solution of the present invention is as follows:

A dolly for adjustable handle-bar, includes vehicle frame, and vehicle frame top is fixed with goods carriage, vehicle frame below is provided with front-wheel and trailing wheel, the left and right sides, vehicle frame rear end forms handle mounting pipe, and handle mounting pipe upper end has tapped bore, is inserted with bolt in tapped bore, sleeve jug in handle mounting pipe, handle comprises handle end and insertion end, and insertion end outside face has annular groove, has circular hole in annular groove, bolt one end sleeve is in circular hole, and the other end is fixed with rotating head.

As preferably, described annular groove quantity is three, and the circular hole quantity in described annular groove is two, described two circular hole distributions in 90 ° and lay respectively at the lateral surface that handle is rectified below and insertion end, and described Circularhole diameter is greater than the diameter of bolt 1 ~ 2mm.

As preferably, described rotating head is positioned at the tapped bore outside in handle mounting pipe.

As preferably, between the handle mounting pipe of the described left and right sides, be welded with stirrup.

As preferably, described vehicle frame integral body is metal circular tube framework.

Beneficial effect of the present invention is:

The present invention has improved handle and handle mounting pipe structure, realized according to the effect of actual requirement flexible rotating or lifting handle, and handle inwardly can be rotated and fixes and saving space when use or placement, in addition, the annular groove of offering and circular hole can conveniently find when regulating adjusts position, after fixing, be difficult for loosening, very firm.

accompanying drawing explanation:

Fig. 1 is texture edge schematic diagram of the present invention;

Fig. 2 is plan structure schematic diagram of the present invention;

Fig. 3 is the local structure for amplifying schematic diagram of the present invention.

In figure: 1, vehicle frame; 2, goods carriage; 3, front-wheel; 4, trailing wheel; 5, bolt; 6, handle; 7, rotating head; 8, stirrup; 11, handle mounting pipe; 61, handle end; 62, insertion end; 63, annular groove; 64, circular hole.

the specific embodiment:

As Figure 1-3, a kind of dolly of adjustable handle-bar, include vehicle frame 1, vehicle frame 1 top is fixed with goods carriage 2, vehicle frame 1 below is provided with front-wheel 3 and trailing wheel 4, vehicle frame 1 left and right sides, rear end forms handle mounting pipe 11, handle mounting pipe 11 upper ends have tapped bore, in tapped bore, be inserted with bolt 5, the interior sleeve jug 6 of handle mounting pipe 11, handle 6 comprises handle end 61 and insertion end 62, insertion end 62 outside faces have annular groove 63, in annular groove 63, have circular hole 64, bolt 5 one end sleeves are in circular hole 64, and the other end is fixed with rotating head 7.

Particularly, described annular groove 63 quantity are three, circular hole 64 quantity in annular groove 63 are two, described two circular hole 64 distributions in 90 ° and lay respectively under handle end 61 and the lateral surface of insertion end 62, and described circular hole 64 diameters are greater than bolt 5 diameter 1 ~ 2mm.The described circular hole 64 that is positioned at insertion end 62 lateral surfaces is fixed after can realizing handle 6 inwardly being rotated to 90 °.

Particularly, described rotating head 7 is positioned at the tapped bore outside in handle mounting pipe 11.

Particularly, 11 of the handle mounting pipe of the described left and right sides are welded with stirrup 8.

Particularly, described vehicle frame 1 integral body is metal circular tube framework.

Principle of work of the present invention is: when needs lifting or rotating handles 6, rotate rotating head 7, bolt 5 is shifted out in circular hole 64, can carry out lifting or rotating handles 6, after adjusting position is determined, rotate again rotating head 7 bolt 5 is moved in circular hole 64, fix handle 6, this structure can conveniently find when regulating adjusts position, after fixing, difficult becoming flexible, very firm, and handle 6 inwardly can be rotated and fixes and saving space when use or placement.

The foregoing is only preferred embodiment of the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, should belong to the scope of protection of the invention.
