Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.

See Fig. 1 ~ Fig. 4, a kind of handle rod, can be applied in go-cart, as the shopping cart, sandy beach go-cart etc. in supermarket, handle rod comprises handle rod 1, lower handle rod 2, handle 3, Telescopic positioning device 4 and handle attaching parts 5, and the top of upper handle rod 1 connects above-mentioned handle 3, in the present embodiment, upper handle rod 13 to be connected by rivet 31 with handle, and handle 3 can in the form of a ring, so that user grips.

Upper handle rod 1 and lower handle rod 2 parallel to each other, and connected by Telescopic positioning device 4 between the two, Telescopic positioning device 4 comprises the below that the first sliding sleeve 41 and the second sliding sleeve 42, first sliding sleeve 41 are positioned at the second sliding sleeve 42.First sliding sleeve 41 is set in the bottom periphery of handle rod 1, and horizontally pass by thread-forming screw 411 between the first sliding sleeve 41 and upper handle rod 1 and connect, the first longitudinal through hole 412 is also offered in first sliding sleeve 41, first sliding sleeve 41 is set in the periphery of lower handle rod 2 by the first through hole 412, and the first sliding sleeve 41 and lower handle rod 2 can relative slidings.

Second sliding sleeve 42 is set in the top periphery of lower handle rod 2, is connected between the two by sliding tube 43, and sliding tube 43 on even keel passes from lower handle rod 2, and two ends extend in the madial wall of the second sliding sleeve 42, realizes thus connecting.Also offer the second longitudinal through hole 421, second sliding sleeve 42 is set in upper handle rod 1 periphery by the second through hole 421 in second sliding sleeve 42, and the second sliding sleeve 42 and upper handle rod 1 can relative slidings.

Sliding tube 43 is in hollow, its inside is provided with locating dowel pin 44 and the spring 45 of level, locating dowel pin 44 extends the second sliding sleeve 42 away from one end of upper handle rod 1, this end is equiped with the draw ring 46 that can pull, after pulling draw ring 46, locating dowel pin 44 can be made to slide along the bearing of trend of sliding tube 43.Upper handle rod 1 offers longitudinally upper spaced apart multiple knock hole 11 on the sidewall of locating dowel pin 44, can insert for the corresponding end of locating dowel pin 44 (end near upper handle rod 1), thus the relative position of handle rod 1 and the second sliding sleeve 42 can be made to fix, also namely make the relative position of pull-up hand lever 1 and lower handle rod 2 fix, thus realize expansion and the contraction of handle rod entirety.

One end of spring 45 abuts with the one end away from upper handle rod 1 in sliding tube 43, the other end then abuts with locating dowel pin 44 one end near upper handle rod 1, make locating dowel pin 44 remain the trend be inserted in the knock hole 11 of handle rod 1 thus, thus make stable connection, integral structure is reliable.

The bottom of lower handle rod 2 connects above-mentioned handle attaching parts 5, and in the present embodiment, lower handle rod 2 is connected with handle attaching parts 5 with nut 52 by screw 51, then is connected with cart body vehicle frame 6 by handle attaching parts 5.

When go-cart uses, handle rod 1 and lower handle rod 2 relative sliding (sliding in corresponding sliding sleeve) can be made as required, thus the knock hole 11 being positioned at bottom (or comparatively below) locating dowel pin 44 inserted on upper handle rod 1, so that handle rod entirety has certain height after launching, be convenient to user and promote go-cart, see Fig. 2 and Fig. 3; When go-cart folding storage, pull draw ring 46 by locating dowel pin 44 from pull-out in knock hole 11, make handle rod 1 and lower handle rod 2 relative sliding again, thus the knock hole 11 being positioned at the top (or comparatively top) locating dowel pin 44 inserted on upper handle rod 1, there is less volume after handle rod overall shrinkage, so that the storage of go-cart entirety, see Fig. 5 and Fig. 6.
