Abstract
Provided is a medical bed or vehicle with walking wheels and a rapid action brake device comprising a bed or a vehicle body, walking wheels and brake cam shafts, wherein the brake cam shafts are provided with cranks and are connected to the walking wheels. The special improvement of the utility model is that the brake cam shafts of the two walking wheels provided at one end of the bed or the vehicle body are respectively connected with two support arms of an action brake pedal, and coupled bars are respectively hinged between the cranks of the brake cam shafts and the cranks of the brake cam shafts provided on the same lateral of the other end of the bed or the vehicle body. The pedal can simultaneously and synchronously realize trig brake of the four walking wheels, or can simultaneously and synchronously release brake, and thereby the utility model has the advantages of easy and rapid operation and reliability of brake.
Description
This utility model relates to a kind of patient of transporting or makes things convenient for patient's equipment, particularly has the hospital bed or the car of road wheel brake unit, belongs to technical field of medical instruments.
At present, when hospital bed that people use always or vehicle for medical use stop walking and need stationary positioned at need, adopt the single-wheel braking, promptly the brakes of each road wheel is independently, needs braking one by one more.So operation is loaded down with trivial details, time-consuming, effort, user is felt very inconvenience.
This utility model purpose is to overcome above-mentioned shortcoming of the prior art and provides a kind of easy and simple to handle, quick, braking to have the hospital bed or the car of road wheel fast braking device reliably.
The purpose of this utility model is realized by following technical scheme:
A kind of hospital bed or car with road wheel fast braking device, it comprises bed or car body, road wheel and the cam brake axle of the band crank that links to each other with road wheel, its special improvements are that the cam brake axle of said bed or two road wheels of car body one end links to each other with two support arms of brake pedal respectively, and the crank of cam brake axle is hinged with trace respectively and between the crank of the cam brake axle of bed or car body other end homonymy.
Above-mentioned hospital bed or car with road wheel fast braking device, the cam brake axle of said bed or two road wheels of car body one end is fixedlyed connected with two support arms of brake pedal respectively;
Above-mentioned hospital bed or car with road wheel fast braking device, two support arms of said brake pedal are hinged with bed or car body respectively, and supporting arm front end is provided with shift fork, and this shift fork matches with finger on the cam brake axle crank;
Hospital bed or car with road wheel fast braking device provided by the utility model can carry out skidding to four road wheels simultaneously synchronously with a pedal, or discharges braking synchronously simultaneously, thus easy and simple to handle, quick, and braking is reliable.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the axle side sketch map of this utility model embodiment hospital bed;
Fig. 2 is the axle side transmission simplified schematic diagram of a kind of embodiment brake unit of this utility model;
Fig. 3 is the local axle side transmission sketch of the another kind of embodiment brake unit of this utility model;
Fig. 4 is this utility model embodiment road wheel brakes sketch map.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
Referring to Fig. 1--Fig. 4, present embodiment are the hospital bed with road wheel fast braking device, comprise a body 1, road wheel 2,5 during it is formed and the cam brake axle 7,18 of the band crank 10,19 that links to each other with road wheel 2,5; Be installed on the crank 10,19 of cam brake axle 7,18 of two road wheels of bed end 2,5 of a body 1, respectively and 13,14 on the crank of the cam brake axle 12,15 of the road wheel of head end homonymy be hinged with trace 11,16.
Shown in Figure 2, brake pedal 4 two support arm 3,6 that are located at the bed end bottom are hinged with bed body 1 respectively, and the shift fork 17,9 of support arm 3,6 front ends matches with finger 20,8 on the crank 19,10 of cam brake axle 18,7.
Shown in Figure 3, the cam brake axle 7,18 of two road wheels of bed end 2,5 is fixedlyed connected with two support arms 6,3 of brake pedal 4 respectively.
Road wheel brakes shown in Figure 4 is a known technology.Said cam brake axle 7,12,15,18 and cam 23 are fixing.When the brake pedal 4 that steps downwards as shown in Figure 2, cam brake axle 7,12,15,18 rotates and also drives cam 23 and rotate, and presses push rod 24 downwards, makes gear wheel 25 and following gear wheel 22 combinations.So just limited the go to action of road wheel, push rod 24 continues descending, and the road wheel contour line 21 that makes down gear wheel 22 bottoms under the effect of frictional force, can not rotate road wheel with after the road wheel outer rim contacts.Upwards lift brake pedal 4, skidding discharges.
