Description
Technical field
The present invention relates to the synchronous Full-brake castor of a kind of two pedal.
Background technology
After people have invented wheel, when mobile large-sized object, just become relatively simple, but the defect of early stage wheel is particularly evident, can only maybe cannot brake by straight line moving, safety when having limited alerting ability when object moves and having stopped, people had just invented the wheel with complete freedom and brake structure afterwards, namely our present alleged castor or cardan wheel.Along with scientific and technological development, increasing equipment need to be handled official business and operation in movement, takes into account multifunctionality, safety and the high usage of equipment, and castor must become indispensable parts.Although the carrying that people are given in the appearance of castor particularly mobile object has brought the efficiency revolution of changing the epoch, but along with client is to the deep cognition of castor performance and the increase of user demand, traditional castor has been proposed to the requirement of higher standard, i.e. the non-blind area of castor operation.
For the mobile device using in different industries, the function of castor and kind are also constantly changing, for example: be used in the industrial castor of the equipment of heavy duty load, or be used in medical castor in the medical health equipment of special protection etc.But in the process of the use of castor, the drawback that traditional Castor structure exists also displays gradually, castor is to complete complete free, the two kinds of braking modes that brake entirely by single pedal, be installed on while moving on equipment, because 360 ° of equipment freely rotate entirely, can drive the pedal access arrangement belly below of wheel, cause controlling the appearance of blind area, thereby equipment cannot be braked in the time must braking, affecting castor uses and device security, this just need to overthrow traditional Castor structure, develops the synchronous Full-brake castor of a two pedal.
Summary of the invention
The object of the present invention is to provide the synchronous Full-brake castor of a kind of two pedal, this castor adopts the design of the synchronous full application of brake of two pedal, no matter tramples which pedal, can complete the operation of full freedom and full brake.
Technical program of the present invention lies in providing a kind of two pedal synchronous Full-brake castor, comprise castor body frame, it is characterized in that: on the center shaft of castor body frame, be provided with for braking or two pedals of brake off, described two pedals towards the opposite, and between two pedals, be provided with synchronous interaction mechanism, so that two pedals can synchronization action.
Above-mentioned body frame both sides are disposed with respectively wheel sheet and side cover, in the axis hole of the axis hole of described body frame and wheel sheet, be provided with cross bar, on described body frame, be also provided with and can make the synchronous brake slide block up and down reciprocatingly sliding along longitudinal chute of body frame, between described synchronous brake upper end of slide block and body frame inner chamber, be provided with retracing spring, two sides of described synchronous brake slide block are respectively arranged with the fan-shaped braking tooth bar for brake wheel sheet, described synchronous brake slide block is that hollow slide block and its middle part are provided with one for the long slot bore through cross bar, be positioned on the cross bar of synchronous brake slide block inner chamber and be equipped with two synchronous braking pedals towards the opposite, on described two synchronous braking pedals, be provided with the cam part for pushing tow synchronous brake slide block upward sliding, between described two synchronous braking pedals, be provided with synchronous interaction mechanism.
The invention has the advantages that: this castor adopts the design of the synchronous full application of brake of two pedal, the two pedal synchronous braking structure being formed by parts such as guiding traction slide block, sync pulling sheet, synchronous brake slide blocks, when stepping on next pedal, carry out full braking, the action that the synchronous generation of another pedal is stopped entirely downwards; Pedal is mentioned while separating braking, also can there is the upwards action of un-brake in another pedal.Therefore, no matter trample which pedal, can complete the operation of full freedom and full brake.
