Description
Technical field
The utility model relates to a kind of single foot-operated Full-brake castor.
Background technology
After people have invented wheel, just become relatively simple when mobile large-sized object, but the defect of early stage wheel is particularly evident, namely can only maybe cannot brake by straight line moving, safety when limiting alerting ability when object moves and stop, people had just invented the wheel with complete freedom and brake structure afterwards, namely we present alleged by castor or cardan wheel.Along with the development of science and technology, increasing equipment needs to carry out handling official business and operation in movement, and take into account the multifunctionality of equipment, safety and high usage, castor must become indispensable parts.Although the efficiency revolution in carrying particularly bringing of mobile object epoch of people is given in the appearance of castor, but along with the deep cognition of client to castor performance and the increase of user demand, traditional castor is proposed to the requirement of higher standard, i.e. the hommization operation of castor.
For the mobile device used in different industries, the function of castor and kind are also constantly changing, and such as: the industrial castor being used in the equipment of load duty, or are used in the medical caster etc. in the medical health equipment of special protection.But in the process of the use of castor, the drawback that traditional Castor structure exists also displays gradually, tradition castor has carried out full brake by trampling stretcher downwards and upwards dialled two kinds of braking modes that stretcher completes un-brake action, along with development, the raising year by year that people require Humanization Design of Products, upwards dial pedal and do not meet epoch and people's require that product hommization to complete un-brake pattern, this just needs to improve traditional Castor structure, and Full-brake castor ridden by the list developing a practical hommization type.
Summary of the invention
The purpose of this utility model is to provide a kind of single foot-operated Full-brake castor, this single foot-operated Full-brake castor structure is simple, reasonable in design, only need trample the different directions of stretcher, just can complete the operation of the freely complete and full brake of castor, more compose hommization and practicality.
The technical solution of the utility model is:
Full-brake castor ridden by the utility model list, comprise castor body frame, described body frame both sides are disposed with the wheel sheet and side cover with internally toothed annulus respectively, cross bar is provided with in the axis hole of described body frame and the axis hole of wheel sheet, it is characterized in that: described body frame is also provided with and can makes the brake pedal of crankmotion by the knock hole on body frame, described brake pedal lower surface is provided with two protuberances for pushing tow lever plectrum tilting forward or downwards, the first retracing spring is provided with between described lever plectrum and body frame inner chamber, be positioned at body frame inner chamber and guide channel is set for bearing the brake facing pumped, described brake facing two side arranges the braking lug for brake wheel sheet internally toothed annulus respectively.
Further, above-mentioned body frame is also provided with longitudinal main shaft, described longitudinal main shaft is provided with dust-proof mainshaft cap, and the lower surface of described dust-proof mainshaft cap is evenly equipped with several pin-and-holes.
Further, be provided with spline latch for spacing longitudinal main axis and the 3rd retracing spring at lever plectrum leading section, described spline latch upper end coordinates with the pin-and-hole of dust-proof mainshaft cap lower end, and described 3rd retracing spring is nested with on the peripheral part of spline latch.
Principle of work of the present utility model: brake pedal is hinged in the knock hole on body frame, lever plectrum is hinged in elongated hole fulcrum, be positioned at body frame inner chamber and guide channel is set for bearing the brake facing pumped, described brake facing two side arranges the braking lug for brake wheel sheet respectively, thus when jamming on rear side of brake pedal top, protuberance presses lever plectrum rear lateral portion moves down, thus drive brake facing and braking lug clamping stagnation to be positioned at the external toothing of body frame two side wheel sheet, achieve the braking of castor, and when trampling on front side of brake pedal top, protuberance presses lever plectrum front side portion moves down, thus tilt the front side portion of lever plectrum, brake facing and braking lug is driven to depart from the external toothing being positioned at body frame two side wheel sheet, achieve the complete of castor freely to rotate.
The utility model has the advantage of: this castor adopts the difunctional design of single pedal plate, the different directions only need trampling stretcher just can complete brake, un-brake operation, without the need to completing un-brake operation with upwards dialling stretcher, this design meets human motion structure feature, convenient operation, has hommization.
