Abstract
The hand cart is characterized in that the wheel frame is hinged with a swing link, the wheel is arranged at one end of the swing link, and a spring is linked between the swing link and the wheel frame or between the swing link and the cart body. The hand cart is characterized in that the wheel frame is hinged with a swing link, and the wheel is arranged at one end of the swing link; a spring is linked between the swing link and the wheel frame or between the swing link and the cart body, and the moment direction caused by the spring force to the swing link is the opposite to the moment direction which is caused by the floor counteracting force to the swing link and is received by the floor. The swing link and the spring of the structure is composed of a shock absorbing apparatus, effectively reducing the noises of the hand cart. The utility model is particularly suitable to use in hospitals, maintaining the quiet environment of the hospitals, and making patients obtain better rest.
Description
Technical field
The utility model relates to hand barrow, the hand barrow that is used to transport article that particularly uses in hospital.
Background technology
The known hand barrow that is used to transport article in hospital does not all have at the wheel place shock absorbing apparatus to be set at present.Hand barrow sends very big noise when walking, especially under indoor environment, noise is more ear-piercing, seriously disturbs patient's rest.
Summary of the invention
The purpose of this utility model provides a kind of hand barrow that can effectively reduce noise.
The technical solution of the utility model is: hand barrow comprises vehicle wheel frame and the wheel that is installed on the car body, especially, on vehicle wheel frame, be hinged with fork, wheel is arranged on an end of fork, between fork and vehicle wheel frame, perhaps be connected with spring between fork and the car body, the moment direction that spring force produces fork, the ground reaction force that is subjected to wheel is opposite to the moment direction that fork produces.Above-mentioned fork, spring constitute a kind of shock absorbing apparatus, and the impulsive force that wheel is subjected to can not act directly on the vehicle wheel frame, thereby have reduced the vibrations of car body, have reduced the noise of hand barrow effectively.
The utility model has the advantages that noise is little, help keeping the quiet environment of hospital, patient is better had a rest.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Fig. 3 is the structural representation of embodiment 3.
The specific embodiment
Referring to Fig. 1, hand barrow comprises vehicle wheel frame 2 and the wheel 3 that is installed on the car body 1.Characteristics of the present utility model are to be hinged with fork 4 on vehicle wheel frame 2, fork 45 swings around the shaft, and wheel 3 is arranged on an end of fork 4.Present embodiment connects spring 6 between fork 4 and vehicle wheel frame 2, its concrete structure be on vehicle wheel frame 2, be provided with one with the solid all-in-one-piece capsule body 7 of vehicle wheel frame, box plate has through hole 8; The other end relative with wheel 3 on fork 4 is connected with a barred body 9, and barred body 9 both can be affixed with fork 4, also can be hinged by jointed shaft 12 and fork 4; The through hole 8 that barred body 9 passes box plate stretches in the box body 7; Spring 6 is a pressure spring, is positioned at box body 7 and is enclosed within on the barred body 9, and the base plate of the lower end of spring 6 and box body 7 contacts, and upper end and a baffle plate 10 that is fixed on the barred body 9 contact.When wheel 3 is subjected to ground shock power, fork 4 clockwise rotates, and fork 4 makes spring 6 compressions by barred body 9, baffle plate 10, thereby plays the buffering and shock preventing effect, the impulsive force that makes vehicle wheel frame 2 and car body 1 be subjected to greatly reduces, and has reduced the noise of hand barrow effectively.Present embodiment is placed on spring 6 in the box body 7; and box body 7 is integral admittedly with vehicle wheel frame 2; the advantage of this structure is to avoid ground foreign matter bump spring; play the effect of protection spring; and, be applicable to that therefore the sort of vehicle wheel frame 2 rotates the cardan wheel structure that connects with car body 1 by pressure bearing 11 because box body 7 can rotate with vehicle wheel frame 2.
Referring to Fig. 2, the difference of present embodiment and Fig. 1 is that box body 7 is fixed on the bottom of car body 1, and its effect is equivalent to spring 6 and is connected between fork 4 and the car body 1.Vehicle wheel frame 2 is fixed on the car body 1 and can not rotates.Other structure is identical with embodiment 1.
More than two kinds of embodiments, the moment direction that 6 pairs of forks of spring 4 produce, all opposite to the moment direction of fork 4 with the ground reaction force that wheel 3 is subjected to.
Claims (4)
1, a kind of hand barrow, comprise the vehicle wheel frame and the wheel that are installed on the car body, it is characterized in that: on vehicle wheel frame, be hinged with fork, wheel is arranged on an end of fork, between fork and vehicle wheel frame, perhaps be connected with spring between fork and the car body, the moment direction that spring force produces fork, the ground reaction force that is subjected to wheel is opposite to the moment direction that fork produces.
2, hand barrow as claimed in claim 1, it is characterized in that: on vehicle wheel frame, be provided with one and the solid little box body of all-in-one-piece of vehicle wheel frame, box plate has through hole, the other end relative with wheel is connected with a barred body on fork, the through hole that barred body passes box plate stretches in the box body, and described spring is a pressure spring, is positioned at box body and is enclosed within on the barred body, the lower end and the box plate of spring contact, and upper end and a baffle plate that is fixed on the barred body contact.
3, hand barrow as claimed in claim 2 is characterized in that: described barred body and fork are affixed.
4, hand barrow as claimed in claim 2 is characterized in that:, described barred body is hinged by jointed shaft and fork.
