Description

Portable stretcher

This utility model relates to a kind of portable stretcher, belongs to the rescue utensil.

At present, the stretcher that is used for hospital or other rescue place mainly contains two kinds, promptly common stretcher and collapsible stretcher.Common stretcher is about 2.3 meters crossbeam, two connecting rod racks and four foot rests by two to be formed, and Folding stretcher is by being about 2 meters, and wide about 0.5 meter aluminum alloy frame is formed, and there is a folding centre, can its doubling is long into about 1 meter, and 0.5 meter wide Folding stretcher.Both common shortcomings are that volume is big, heaviness, and inconvenience is carried.

The purpose of this utility model is that a kind of volume is little, and is in light weight, portable portable stretcher.

The purpose of this utility model is achieved in that accompanying drawings is as follows: Fig. 1 is the structural representation after this utility model folds.Portable stretcher is made up of support and foot rest between two beams and the beam, every beam is respectively by two straight tubes 3,3 ' by articulated slab 4,4 ' connection, trombone slide 1,1 ' respectively by sleeve pipe 2,2 ' insertion straight tube 3,3 ' in, and it is spacing by position-limit mechanism, between two straight tubes 3 and two direct 3 ' between be equipped with respectively Collapsible rack 5,5 ', foot rest be located at respectively straight tube 3,3 ' on Collapsible rack 5,5 ' locate, foot rest on the straight tube 3 be equipped with the wheel 7, straight tube 3 ' on foot rest be rear leg 6.

The technical scheme that this utility model provides mainly designs from following three aspects, the one, whole beam is divided into two parts, promptly adopt two straight tubes hinged, can make whole stretcher doubling so together, can make its length approximately shorten near half; Two is to adopt Collapsible rack to connect between two beams, and two beams are stitched together, and the width of stretcher is obviously reduced; The 3rd, beam adopts sleeve structure, and trombone slide can be pulled out or indentation in straight tube, and the length of stretcher is further shortened on the basis of shortening half.

This utility model is compared with collapsible stretcher with existing common stretcher and had the following advantages: 1, volume is little, and is in light weight, is easy to carry; 2, open, fold rapidly, easy to use, reliable, be specially adapted to the open-air rescue of army and hospital's eruption first aid; 3, can utilize the space in the trombone slide to adorn some first-aid medicines and utensil, and can in the paving of stretcher, dispose first-aid kit, make its rescue function more perfect.

Further specify particular content of the present utility model below in conjunction with embodiment shown in the drawings.

Fig. 1 is the structural representation of this utility model after folding, and Fig. 2 is Fig. 1 along the view of articulated slab 4,4 ' after opening, and Fig. 3 is the vertical view after Fig. 2 opens Collapsible rack 5, and Fig. 4 is a position-limit mechanism cutaway view of the present utility model, and Fig. 5 is the side view of Fig. 4.

Consult Fig. 1: 1,1 ' be trombone slide, 2,2 ' be sleeve pipe, 3,3 ' be straight tube, 4,4 ' be articulated slab, 5,5 ' be Collapsible rack, the 6th, rear leg, the 7th, wheel.Trombone slide 1,1 ', sleeve pipe 2,2 ', two beams of straight tube 3,3 ' formation portable stretcher.Its connection can be consulted Fig. 1, Fig. 2, Fig. 3: trombone slide 1,1 ' for the multidiameter shape, sleeve pipe 2,2 ' endoporus be shoulder hole, trombone slide 1, the 1

' sleeve pipe

2,2 of packing into ' in, sleeve pipe 2,2 ' be sleeved on straight tube 3,3 ' go up and fix with it.Trombone slide 1,1 ' and sleeve pipe 2,2 ' and straight tube 3,3 ' between be slidingly matched.Said structure can guarantee trombone slide 1,1 ' cover 2,2 ' and straight tube 3,3 ' interior freely pulling out and indentation.Straight tube 3,3 ' by articulated slab 4,4 ' connection.Collapsible rack 5,5 ' be to form by two parts are hinged, its outer end is contained on carriage 9 and the foot rest by bearing pin 10, and can rotate along the lower surface of carriage 9.It is the width of stretcher that Collapsible rack launches the back, and after folding, two beams are put together.Rear leg 6 and wheel 9 are fixed on sleeve pipe 2,2 ' locate.

After stretcher is opened, trombone slide 1,1 ' from sleeve pipe 2,2 ' and straight tube 3,3 ' in pull out back location, at two sleeve pipes 2 and two sleeve pipes 2 ' locate to be provided with position-limit mechanism, its structure is consulted Fig. 4: this mechanism is by key 8 and steel ball 12, supporting plate 9 and shifting block 11 are formed, key 8 is contained in trombone slide 1, on the outer wall of 1 ' the inner, sleeve pipe 2,2 ' inwall be provided with keyway, sleeve pipe 2,2 ' lower wall on fix a supporting plate 9, at each sleeve pipe 2,2 ' lower wall on, trombone slide 1,1 ' wall on and supporting plate 9 on the corresponding position perforate, steel ball 12 places sleeve pipe 2,2 ' and the hole of supporting plate 9 in, sleeve pipe 2, aperture on 2 ' lower wall is greater than trombone slide 1,1 ' the aperture, aperture on the supporting plate 9 is slightly less than the diameter of steel ball 12 and guarantees that the part of steel ball exposes the lower surface of supporting plate, pulling block (11) is contained in Collapsible rack (5), on (5 '), it can be with Collapsible rack (5), folding or the expansion of (5 ') is moved along the lower surface of supporting plate 9.This mechanism's work process is: when stretcher around articulated slab 4,4 ' after opening, before Collapsible rack does not launch as yet fully, with trombone slide 1,1 ' be pulled outwardly and rotate, key 8 is entered in the keyway, this moment be positioned at sleeve pipe 2 ' steel ball 12 face trombone slide 1, hole on 1 ' wall, because open on lower wall in this hole, steel ball 8 is being held in the palm by the hole on the supporting plate 9 and a part of lower surface that exposes supporting plate 9, when Collapsible rack 5,5 ' when continuing to launch, the pulling block 11 of its end moves to the place, hole with steel ball 12 picking-ups along the lower surface of supporting plate 9, make its top enter trombone slide 1, in 1 ' hole, thereby define trombone slide 1,1 ' axial float, simultaneously also define axial rotation with key 8, realized the position-limiting action of trombone slide.

Laterally folded for stretcher is realized, the support Design that is contained between two beams becomes folding structure.Concrete structure is a Collapsible rack 5,5 ' be respectively two poles, and its inner is hinged, and the outer end is contained on supporting plate 9 and the foot rest by bearing pin 10, and can rotate around the lower surface of bearing pin 10 along supporting plate 9, Collapsible rack 5,5 ' the outer end be provided with pulling block 11.After guaranteeing that Collapsible rack launches, the width of stretcher is collapsible, and support adopts unidirectional-folding, inwardly adopts in the present embodiment to fold, and can add position-limited edge in the outside of support overlapping.

Dress wheel 7 on this utility model pro-foot rest is convenient to single push-and-pull operation.
