Abstract
The utility model belongs to a controllable universal hand cart used for transporting serious patients or small articles in short distance. The hand cart comprises a frame, a universal wheel and an armrest. The utility model is mainly characterized in that a nut, a pressure spring plate, a pressure spring and a screw which are arranged in the circular tubes of right and left armrests at the back end on the upper part of the frame are fixedly connected with each other through a draw rod which is fixed at the overhang end of the pressure spring plate, a guide plate which is supported by a shaft and is arranged at the front lower part of the frame by abutting to the universal wheel and a direction lock device which is composed of a lever and is used for connecting with the left and right pressure spring plates. The utility model has the advantages of steady run and wide adaptability, which can not only control direction arbitrarily, but also can reserve the movable and agile superiority of the universal wheel.
Description
The utility model relates to the hand barrow that heavy patient or small article are transported in a kind short range, particularly a kind of controllable universal go-cart.
Go-cart has very long history, and kind is many, and purposes is wide, even in communications and transportation very flourishing today, still have its effect that can't replace, such as hospital, supermarket, hotel, family etc. higher frequency of utilization is arranged all.But the existing four-wheel go-cart in home market, performance configuration with wheel, be divided into three kinds of forms: one: front and back wheel is directional wheel, the four-wheel go-cart smooth running of this form, but direction is dumb, can not do low-angle turning,, thereby limit its range of use in narrower and small local or mobile on the spot difficulty; Its two: the first two be a directional wheel, and back two be cardan wheel, the four-wheel go-cart smooth running of this form, direction flexibly, can do low-angle turning, but in narrower and small local or mobile on the spot still inconvenience; Three, four wheels is cardan wheel, the four-wheel go-cart smooth running of this form, can move, not be subjected to local size restriction, very flexible to any direction, but yet has a direction of travel heavy handled shortcoming.By the retrieval of existing Chinese patent literature is looked into newly, though these patented technologies improve to some extent, but still there are some above-mentioned shortcoming in three pieces of patent documentation: zL97214749.7, the zL94215190.9, the zL96232351.9 that are found on some structure.
The purpose of this utility model is to provide a kind of and divides front and back with four cardan wheels, and sets up a cover directional locking to control the controllable universal go-cart of two front-wheel directions.
The utility model purpose realizes with following technical proposal: this controllable universal go-cart, comprise vehicle frame, cardan wheel and handrail, in the right and left handrail pipe of rear end, vehicle frame top set nut, pressure spring plate, stage clip, the screw rod pull bar by being fixed on the pressure spring plate overhanging end be located at the directional locking that the preceding bottom of vehicle frame is affixed near the guide plate with the axle supporting of cardan wheel and is connected the joystick composition of left and right sides pressure spring plate.
Said stage clip and pressure spring plate be sleeved on the screw rod and the stage clip front end be fixed on the pressure spring plate, and with the nut relative fixed.Said guide plate forms an angle and is provided with an inclined-plane in its lower end by the cardan wheel side.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a sectional structure scheme drawing of the present utility model.
As shown in the figure: 1-vehicle frame, 2-nut, 3-pressure spring plate, 4-stage clip, 5-screw rod,
6-pull bar, 7-axle, 8-guide plate, 9-cardan wheel, 10-handrail,
The 11-joystick.
With reference to Fig. 1,9 fens front and back of 4 cardan wheels are assembled in vehicle frame 1 bottom; Be provided with an axle 7 that can rotate flexibly apart from preceding cardan wheel 9 suitable positions, each fixes its two end distances cardan wheel, 9 inboard 1-2mm places one and forms certain angle and there is a guide plate 8 in order to the inclined-plane that inserts cardan wheel 9 inboards the lower end; The affixed pull bar 6 in guide plate 8 upper ends, the pressure spring plate 3 of the left and right sides, vehicle frame 1 upper back handrail 10 in overhanging pipe is affixed with being located at; Insert 1 screw rod 5 in the handrail pipe of the left and right sides symmetrically, be set with pressure spring plate 3 and fastening stage clip 4 on it thereon, and with nut 2 relative fixed; Left and right sides handrail 10 links to each other by a cross bar, and its connecting rod is the holding rod of handrail 10; The overhanging pressure spring plate 3 in the left and right sides also links to each other with a cross bar, and its connecting rod is direction lever locked 11, is positioned at before handrail 10 connecting rods.
Its working process is: go-cart when walking, hand is placed on handrail 10 holding rods, palm down, thumb after catch holding rod, all the other 4 are caught direction lever locked 11 before pointing to and hold with a firm grip.Because handrail 10 holding rods are fixed, and direction lever locked 11 is being supported by stage clip 4, after stressed, after shrinking, moves by stage clip 4, move after driving pressure spring plate 3, and then move after driving pull bar 6, moved backward in guide plate 8 upper ends and drive its lower end and shift forward and insert two preceding cardan wheel 9 inboards, blocking cardan wheel 9 can not turn to, and makes it temporarily change into directional wheel.At this moment, utilize after two swinging of cardan wheel 9 can control the direction of travel of go-cart freely.When go-cart enters narrower and small local or need when mobile on the spot, unclamp direction lever locked 11, pressure spring plate 3 resets because of the tension force of stage clip 4, just the motion opposite with above-mentioned direction takes place and breaks away from two preceding cardan wheel 9 inboards in pull bar 6 and guide plate 8, releasing is to the direction restriction of preceding cardan wheel 9, recover its universal function, go-cart can be moved flexibly to any direction.
In sum, the utility model is compared with existing handcart, has smooth running, both can arbitrarily control Direction, kept the advantage of universal wheel maneuverability again, used this technology and can design the hand that is fit to various demands The advantages such as go-cart.
