Abstract
The utility model discloses a stretcher with wheels, relating to equipment of delivering the patient. The utility model is characterized in that two lateral rods on the front and back sides of the stretcher are connected with the long pole provided with supporting wheels and hooks on the left and right sides via a safety plug. A concave opening on the rod of the supporting wheel is clamped mutually with the corresponding part on a level in the positioning device of the forward part of the rod of the supporting wheel, a lever guiding wheel is linked on the positioning device of a first supporting wheel. The lateral rods can be dismountable in order to make the stretcher become narrow, which is convenient for placing and carrying. The stretcher with the supporting wheels can be pushed on flat ground, or a long pole hung is hung on the rod of the supporting wheel, the stretcher can be lifted for moving; When the stretcher gets on and off an ambulance, the positioning device loosens or clamp, the rod of the supporting wheel can rotate or position, and the stretcher can conveniently enter or go out of the inner part of the cart, which lightens the labor intensity of rescuing persons.
Description
This utility model relates to the equipment that transports patient.
Having suffered from the sick patient of anxious danger often needs to be rushed to hospital immediately, and this uses stretcher to transport patient often, and carries on ambulance.Normally used stretcher is to lift by the people, and relatively effort when particularly carrying on ambulance, is felt inconvenience very much, and patient feels unstable; Have the go-cart of wheel to transport patient convenient, but that car takes up space is too big, inconvenience enters ambulance.
Task of the present utility model is will provide a kind of can transport patient as the go-cart stretcher of the ambulance of coming in and going out easily again.
Task of the present utility model is finished as follows: with two cross bars before and after the stretcher by safety plug with each side be connected with the stock of two support wheels at least, it is that corresponding site blocks mutually on recess and the lever on the support wheel bar that all there is a location device in the place ahead of each support wheel, connect a lever guide wheel on the positioner of first support wheel, in two stock inboards hook is housed, when stock is pressed close in the support wheel backswing, its pike pole is lived.
Front and back of the present utility model two cross bars after pressing safety plug, can break away from stock, therefore, when stretcher does not use, or corridor, when the ambulance place is narrow and small, stretcher are narrowed down.Have and be convenient to the advantage of laying and carrying.Stretcher is the transport disease man-hour on the level land, and support wheel lands, and only need push away or draw row.When stretcher is pushed to ambulance, two lever guide wheels head on platform floor, under the effect of thrust and envelope base plate resistance, this is taken turns upwards and raises, positioner is thrown off, and stock is close in the first support wheel backswing, clashes into the positioner of a back support wheel simultaneously, make the support wheel backswing, stretcher just can successfully roll in the car.When stretcher was drawn out ambulance, support wheel was subjected to gravity fall and location, the stretcher ambulance of can coming in and going out easily.When running into Uneven road or going up downstairs, support wheel can be gone to the stock place also with hooking.Stretcher can lifted easily, can alleviate rescue work personnel's labor intensity widely.
Below with reference to accompanying drawing utility model is described in further detail.
Fig. 1 is the concrete structure sketch map of this utility model embodiment.
Fig. 2 is the positioning device structure sketch map of this utility model embodiment.
Fig. 3 is the another kind of structural representation of the positioner of this utility model embodiment.
With reference to Fig. 1, cross bar 1, left and right sides stock 2, fixed cover 3, safety plug 12, support wheel 5, lever 4, lever guide wheel 6, positioner 14, hook 7, canvas 8 before and after this utility model embodiment comprises.Positioner 14 is made up of lever 4, retainer spring 9, back-moving spring 10, support wheel 5 bars.Cross bar 1 by safety plug 12 with each side have two fixed covers 3 and link to each other with two hook stocks 2 of 7.Support wheel 5 bars link by rotating shaft and fixed cover 3, and 1/4th ratchets that contain three ratchets are at least milled in support wheel 5 bar right sides, and it is matched with the lever 4 that mills into ratchet shape.Retainer spring 10 two ends are hooked in respectively on the respective aperture of fixed cover 3 and lever 4.Back-moving spring 9 two ends are hooked in respectively on the respective aperture of fixed cover 3 and support wheel 5 bars.Lever 4 in the positioner 14 of first support wheel 5 is equipped with lever guide wheel 6.
During use, open stretcher and set level, cross bar 1 pushes away and installs on the stock 2.Patient is carried on stretcher, when pushing ambulance, lever guide wheel 6 is pushed the rising certain altitude and is rolled into platform floor, downward with lever 4 other ends that lever guide wheel 6 fuses, support wheel 5 breaks off relations, after put the lever 4 that clashes into simultaneously to stock 2 places in the positioner 14 of next support wheel 5, make on it and lift, positioner 14 breaks off relations, and is same, support wheel 5 backswing.Stretcher is successfully pasting the ambulance envelope and is rolling in the car.When stretcher is got off, only need be pulled outwardly cross bar 1, four support wheels 5 are because of being subjected to the effect bottom of gravity and back-moving spring 10 retainer springs 9, when support wheel 5 bars and ground are 90 °,, thereby can not swing to the right again because support wheel 5 bar right side ratchet top edge and stock 2 withstand, thereby stretcher also can draw row, simultaneously, the ratchet of lever 4 hooks ratchet at the ratchet that slips under the effect of back-moving spring 10 on support wheel 5 bars, thus the location.During if need carry a stretcher, after ratchet and ratchet disengaging, rotational support is taken turns 5 bars and is adjacent to stock 2, and hooks with hook 7.
With reference to Fig. 3, there are the iron plate of a breach, the ratchet of lever 4 to make the tooth that matches with breach on the ratchet on support wheel 5 bars in the positioner among the embodiment 14 instead.
