Abstract
The utility model discloses a bucket type telescopic stretcher, comprising a stretcher body and a stretcher telescopic part, wherein two telescopic rods are arranged on two sides of the inner end part of the stretcher telescopic part; a plurality of position holes are uniformly formed in the telescopic rods; two sleeves are correspondingly arranged on the stretcher body; positioning locks are arranged on the mouths of the sleeves at the stretcher body; the telescopic rods are sleeved in the sleeves; lock pins of the positioning locks correspond to the positions of the position holes of the telescopic rods. The bucket type telescopic stretcher is characterized in that the cross sections of the telescopic rods on the stretcher telescopic part are polygonal, and the cross sections of the sleeves on the stretcher body are identical to the cross sections of the telescopic rods in shapes and are adaptive to the cross sections of the telescopic rods in sizes. The bucket type telescopic stretcher is simple in structure, convenient, reliable, and capable of effectively preventing the horizontal rotation of the telescopic rods in the sleeves, ensuring the corresponding positions of the position holes and the lock pins, facilitating the smooth entrance of the lock pins into the position holes, and enabling the stretcher to conveniently and freely stretch.
Description
Technical field
This utility model relates to a kind of retractable litter, especially relates to a kind of shovel retractable litter.
Background technology
Existing shovel retractable litter consists of stretcher main body and pars contractilis, the inner end both sides of pars contractilis are provided with two expansion links, on expansion link, evenly offer some gears hole, in stretcher main body, be correspondingly provided with two sleeve pipes, stretcher main body is provided with positioning lock at sleeve opening place, expansion link is inserted in sleeve pipe, and the lock pin of positioning lock is inserted in the gear hole of expansion link, and stretcher length is locked.When stretcher need to stretch, pull open lock pin, lock pin is extracted out from gear hole, pulls the pars contractilis of stretcher to appropriate location, then turns back lock pin, again pulls stretcher pars contractilis, and lock pin falls into gear hole in the elastic force effect of spring, and stretcher length is locked.
But the expansion link of existing shovel retractable litter and sleeve pipe, be circular pin or pipe, section is circle.Because stretcher has distortion, therefore can cause expansion link lateral rotation in sleeve pipe, make gear hole not corresponding with the position of lock pin, lock pin cannot insert gear hole.
Utility model content
Problem to be solved in the utility model, is to overcome the defect that prior art exists, and has proposed a kind of shovel retractable litter, can effectively prevent expansion link lateral rotation in sleeve pipe, has guaranteed the relative position of gear hole and lock pin.
This utility model shovel retractable litter, comprise stretcher main body and stretcher pars contractilis, the inner end of stretcher pars contractilis (stretcher main body one end relative with stretcher pars contractilis is the inner) both sides are provided with two expansion links, on expansion link, evenly offer some gears hole, in stretcher main body, be correspondingly provided with two sleeve pipes, stretcher main body is provided with positioning lock at sleeve opening place, and expansion link is inserted in sleeve pipe, and the lock pin of positioning lock is corresponding with the gear hole site of expansion link; It is characterized in that: the cross section of the expansion link on described stretcher pars contractilis is polygon, the cross section of the sleeve pipe in stretcher main body is identical with the shape of cross section of expansion link and size is adaptive.
This utility model, simple in structure, convenient and reliable.Can effectively prevent expansion link lateral rotation in sleeve pipe, guarantee the relative position of gear hole and lock pin, be convenient to lock pin and enter smoothly in gear hole, make stretcher convenience capable of expansion and contraction.

Fig. 2 is I position partial enlarged drawing in Fig. 1.
Fig. 3 is expansion link and positioning lock assembly relation schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further details.
This utility model shovel retractable litter, comprise stretcher main body 1 and stretcher pars contractilis 2, the inner end of stretcher pars contractilis (stretcher main body one end relative with stretcher pars contractilis is the inner) both sides are provided with two expansion links 3, on expansion link, evenly offer some gears hole 4, (two sleeve pipes are positioned at inside, stretcher main body both sides in stretcher main body, to be correspondingly provided with two sleeve pipes, do not draw in the accompanying drawings), stretcher main body is provided with positioning lock 5 at sleeve opening place, expansion link is inserted in sleeve pipe, the lock pin 6 of positioning lock is corresponding with 4 positions, gear hole of expansion link, that is to say, evenly lay along straight line on expansion link in gear hole on expansion link, 6 pairs of the lock pins of positioning lock are on the straight line at place, gear hole.Expansion link on described stretcher pars contractilis is selected metal tube, and its cross section is regular polygon, as regular pentagon, regular hexagon etc.The cross section of the sleeve pipe in stretcher main body is selected the shape identical with the cross section of expansion link, and size is adaptive, and the internal diameter of sleeve pipe is slightly larger than the external diameter of expansion link.
