Abstract

The utility model discloses a hand transfer cart for patients. The utility model is characterized in that a spring is cushioned between a frame and a bed plate. The spring has the functions of shock absorption and buffering, which increases the comfortableness of the transfer cart and reduces the pain of the patient caused by bumpiness.

Description

Hand push patient carriage

Technical field

This utility model relates to the trolley structure that is used to transport patient.

Background technology

Hand push patient carriage is mainly made the transport disease human in hospital, its structure comprises the vehicle frame of a band wheel, is placed with bed board on the vehicle frame.In prior art, whole vehicle frame does not all have damping, causes that patient's is uncomfortable even painful.

Summary of the invention

The purpose of this utility model provides a kind ofly increases comfortableness, alleviate the hand push patient carriage that patient causes suffering because of jolting.

This utility model is achieved in that hand push patient carriage comprises the vehicle frame of a band wheel, is placed with bed board on the vehicle frame, especially, is lined with spring between vehicle frame and bed board.Because this utility model has been set up spring between vehicle frame and bed board, therefore have the damping, buffering effect, increased comfortableness, alleviated the misery that patient causes because of jolting.

The utility model has the advantages that to make the patient who is transported more comfortable, reduce patient and particularly just finished the wound danger that the patient of operation causes because of jolting, safer, comfortable.

The specific embodiment

But installation site, quantity and the fixed form flexible design of spring on vehicle frame as long as can fix spring, and can play the damping, buffering effect and get final product between bed board and vehicle frame.Referring to Fig. 1, Fig. 2, what present embodiment adopted is helical spring 1 simultaneously, and spring 1 is placed in two

sleeves

2,3 that connect together and can slide mutually, and the sleeve 3 that wherein is positioned at the below is fixed on the vehicle frame, and the sleeve 2 that is positioned at the top is supporting bed board 4.Following square socket 3 both can be fixed on the crossbeam 5 of vehicle frame, also can be fixed on the longeron 6 of vehicle frame both sides.Whole vehicle frame generally should be arranged four spring mounting points at least, so that can support bed board reposefully.For reducing the collision friction noise between bed board and the last square socket, be preferably in fixedly rubber blanket 7 of telescopic top, top.

As further improvement, embodiment shown in Figure 3 is lined with hydraulic pressure shock absorber 8 between spring 1 and last square socket 2.Cushioning effect is played in the hydraulic pressure shock absorber, can avoid the hard collision that excessively causes because of the spring pressurized.The operation principle of hydraulic pressure shock absorber is the same with existing hydraulic pressure shock absorber, can select for use from existing hydraulic pressure shock absorber.

In order to prevent the distortion that radially bends of spring, and prevent that square socket is from coming off in the square socket down, embodiment shown in Figure 3 is also overlapping a limit stick 9 in the threaded hole of spring 1, the bottom of the upper end of limit stick and hydraulic pressure shock absorber 8 is fixed, the lower end passes down the bottom of square socket 3 and is inserted with spacer pin 10, and the top of hydraulic pressure shock absorber 8 and last square socket 2 are fixing.Limit stick 9 plays and prevents that spring 1 from radially bending the effect of distortion; Last square socket 2, hydraulic pressure shock absorber 8, limit stick 9 are fixed together, and play to prevent that square socket 2 is from playing the effect that comes off in the square socket 3 under the restriction of spacer pin 10.

For the ease of for spring filling lubricating oil, also can shown in Fig. 2,3, offer oil filler point 11 on the telescopic up barrel.Add lubricating oil by oil filler point and can make spring 1 remain on wet face state, play and reduce noise and prolong the spring effect in service life.For preventing that lubricating oil from spilling from the bottom of following square socket 3, go back one in infra square socket 3 overcoats among Fig. 3 and contain oil drum 12.Contain below that oil drum both can be fixed on crossbeam 5 and also can be fixed on the outside wall surface of sleeve 3.

In order further to improve the whole damping performance of hand push patient carriage, also spring shock absorption mechanism can be set on the feet of wheel.Referring to Fig. 1, Fig. 4, the feet of wheel has two

section

13,14 that mutual socket also can be slided mutually, in epimere 13, be placed with two sleeves 15,16 that connect together and can slide mutually, be placed with helical spring 17 in two sleeves, between spring 17 and sleeve 15, be lined with hydraulic pressure shock absorber 18, be with a limit stick 19 in the threaded hole of spring, the lower end of limit stick is fixed with following square socket 16, and the hypomere 14 of wheel feet acts on down the bottom of square socket 16.The vibrations of wheel 20 are delivered to the sleeve 16 that is positioned at the below by the hypomere 14 of wheel feet, just are delivered to vehicle frame after shaking force process spring 17 and hydraulic pressure shock absorber 18 bufferings, thereby have improved the whole damping performance of carriage.The effect of hydraulic pressure shock absorber 18 and limit stick 19 is the same with the effect of limit stick 9 with the hydraulic pressure shock absorber 8 among Fig. 3.Sleeve 15 among Fig. 4 acts directly on the longitudinal beam 6, can be the baffle plate of epimere 13 internal fixation at the wheel feet in addition, and sleeve 15 is acted on this baffle plate.
