Abstract
The invention discloses a telescopic stretcher, which comprises two longitudinal bars and multiple connecting cross bars connecting the two longitudinal bars, wherein each longitudinal bar consists of an outer hollow pipe and an inner hollow pipe which are nested together; the inner hollow pipes of the two longitudinal bars are symmetrically arranged on the same end of the stretcher; each inner hollow pipe is provided with troughs matched with the end parts of the connecting cross bars along the axial direction of the inner hollow pipe; a compression spring is arranged in each trough; two adjacent connecting cross bars in the trough are connected by a compression spring; the middle of each connecting cross bar is provided with a horizontal section; two ends of the horizontal section are upwards bent and are respectively in matched connection with the corresponding positions of the two longitudinal bars. According to the telescopic stretcher disclosed by the invention, because the inner sides of the inner hollow pipes are provided with the troughs and the compression springs are arranged in the inner hollow pipes, the connecting cross bars can backwards retract along with the compression of the compression springs when the inner hollow pipes of the stretcher are retracted into the outer hollow pipes, interference brought by fixing the connecting cross bars is avoided, and finally, the purpose of enabling the stretcher to stretch under the condition that the connecting cross bars are not reduced is realized.
Description
Technical field
The present invention relates to a kind of medical stretcher, especially a kind of scalable stretcher.
Background technology
Along with social development, high-rise building is more and more, but because elevator cab narrow space, when from high level, down transporting the patient who lies low, will be very inconvenient, in order to address this problem, medical stretcher of the prior art roughly can be divided into and have two kinds, a kind of is Foldable type, and a kind of is telescopic.In the stretcher of telescopic, generally by increasing or dwindling non-supporting and space and realize stretching.Use such stretcher, when running into the patient that body weight is larger, the intensity of stretcher will be inadequate, thereby the potential safety hazard of causing even there will be accident, to patient, brings extra injury.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides scalable stretcher a kind of simple in structure, easy to use.
The technical scheme that the present invention adopts in order to solve the problems of the technologies described above is: a kind of scalable stretcher, comprise that two vertical poles connect cross bar with the complex root that is connected two vertical poles, described vertical pole is comprised of the hollow outer tube nested together and interior hollow pipe, the interior hollow pipe of two vertical poles is symmetricly set on the same end of described stretcher, on described interior hollow pipe, along it, be axially arranged with and the groove that is connected the crossbar end cooperation, be provided with Compress Spring in groove, be positioned at groove, and connected by Compress Spring between two adjacent connection cross bars; Be respectively equipped with spherical spring button and the hole of matching on interior hollow pipe and hollow outer tube, described hole is spaced a plurality of, and described spherical spring button is fixedly connected with the vertical Compress Spring II be located in interior hollow pipe.
The middle part of described connection cross bar is provided with a horizontal segment, and the two ends of horizontal segment are bending upwards, and with the corresponding site of two vertical poles, is connected respectively.
The side contacted with ground at scalable stretcher is arranged with 6 pads.
Beneficial effect:
According to the present invention, because the inboard at interior hollow pipe arranges groove and in interior hollow pipe, Compress Spring is set, when thereby in stretcher, hollow pipe is to the hollow outer tube indentation, connect cross bar also can along with Compress Spring compression and shrink back backward, and avoided being fixedly connected with the interference that cross bar brings, finally can realize the purpose that stretcher is flexible in the situation that do not reduce the connection cross bar.
The accompanying drawing explanation
Fig. 1 is front view of the present invention.
The top view that Fig. 2 is Fig. 1.
The A-A view that Fig. 3 is Fig. 2.
Fig. 4 is the B-B zoomed-in view of Fig. 2.
In figure, 1, interior hollow pipe, 101, groove, 2, connect cross bar, 3, hollow outer tube, 4, the Compress Spring I, 5, a pad, 6, spherical spring button, 7, hole, 8, the Compress Spring II.
The specific embodiment
As shown in the figure, a kind of scalable stretcher, comprise that two vertical poles connect cross bar 2 with the complex root that is connected two vertical poles, described vertical pole is comprised of the hollow outer tube 3 nested together and interior hollow pipe 1, the interior hollow pipe 1 of two vertical poles is symmetricly set on the same end of described stretcher, on described interior hollow pipe 1, along it, be axially arranged with and the groove 101 that is connected cross bar 2 ends cooperations, be provided with Compress Spring I 4 in groove 101, be positioned at groove 101, and connected by Compress Spring I 4 between two adjacent connection cross bars 2; Be respectively equipped with spherical spring button 6 and the hole 7 of matching on interior hollow pipe 1 and hollow outer tube 3, described hole 7 is spaced a plurality of, and described spherical spring button 6 is fixedly connected with the vertical Compress Spring II 8 be located in interior hollow pipe 1.
In order to allow patient can lie more comfortablely on scalable stretcher, safer, the middle part of described connection cross bar 2 is provided with a horizontal segment, and the two ends of horizontal segment are bending upwards, and with the corresponding site of two vertical poles, is connected respectively.
The side contacted with ground at scalable stretcher is arranged with 6 pads 5, and in order to lay scalable stretcher, as shown in Figure 1, a pad 5 is arranged on and connects the side that cross bar 2 contacts with ground this specific embodiment.
When in order to save the space that takies elevator cab, when the present invention need to shrink, firmly in pushing, hollow pipe 1 advances to hollow outer tube 3, when interior hollow pipe 1 advances to the connection railing 2 on it, connect railing 2 along groove 101 along with the compression of Compress Spring I 4 is shunk back backward, after contraction puts in place, spherical spring button 6 matches and fixes with the hole 7 on hollow outer tube 3.When space is open, when patient can stretch both legs, inner tube is outwards stretched to fix to be got final product.
Claims (3)
1. a scalable stretcher, comprise that two vertical poles connect cross bar (2) with the complex root that is connected two vertical poles, it is characterized in that: described vertical pole is comprised of the hollow outer tube nested together (3) and interior hollow pipe (1), the interior hollow pipe (1) of two vertical poles is symmetricly set on the same end of described stretcher, above along it, be axially arranged with and be connected the groove (101) of cross bar (2) end cooperation at described interior hollow pipe (1), be provided with Compress Spring I (4) in groove (101), be positioned at groove (101), and by Compress Spring I (4), connected between adjacent two connection cross bars (2), be respectively equipped with spherical spring button (6) and hole (7) of matching on interior hollow pipe (1) and hollow outer tube (3), described hole (7) is spaced a plurality of, and described spherical spring button (6) is fixedly connected with the vertical Compress Spring II (8) be located in interior hollow pipe (1).
