Description
Technical field
The utility model relates to a kind of two pedal control castor.
Background technology
After people have invented wheel, it is simple relatively just to become when mobile large-sized object, but the defective of early stage wheel is particularly evident, namely can only maybe can't brake by straight line moving, alerting ability when having limited movement of objects and the safety when stopping, people had just invented the wheel that has full freedom and brake structure afterwards, just our present alleged castor or cardan wheel.Along with the continuous development of science and technology, more and more equipments need be handled official business in movement and operation, takes into account multifunctionality, safety and the high usage of equipment, and castor must become indispensable parts.Though the carrying that people are given in the appearance of castor particularly mobile object has brought the efficient revolution of changing the epoch, but along with the client to the deep cognition of castor performance and the increase of user demand, the requirement of higher standard has been proposed traditional castor, i.e. the convenience of castor operation.
Use the brake castor of single pedal, in braking with remove when switching between the brake, the force direction that is subjected to that needs the user constantly to change foot is finished operation to castor, needs push down on the pedal when for example braking; Need lift when removing brake and step on.As run into for a long time and the situation of braking repeatedly, can allow the user do not feel like oneself, therefore be necessary to change by trampling/mention the traditional approach that pedal carries out the castor braking by increasing accessory by improving the structure of original castor.
Summary of the invention
The purpose of this utility model is to provide a kind of two pedal control castor, and the brake pedal of this castor and un-brake pedal are arranged on same sidepiece, and braking is subjected to force direction identical when operate with un-brake, uses flexibly, makes things convenient for.
The technical solution of the utility model is to provide a kind of two pedal control castor, comprise the castor body frame, described castor body frame both sides are disposed with wheel sheet and side cover respectively, the described wheel has the braking gear ring on the sheet, the inner chamber of described castor body frame is provided with the brake silpper that can up and down reciprocatingly slide, be provided with second retracing spring be used to the brake silpper that resets between the inner chamber of described brake silpper upper lateral part and castor body frame, the sidepiece of described brake silpper is provided with the fan-shaped braking tooth bar that cooperates for the braking gear ring, described brake silpper is that hollow slide block and its middle part are provided with one for the long slot bore that passes cross bar, it is characterized in that: be positioned on the cross bar of brake silpper inner chamber and be equipped with a brake pedal, described brake pedal is provided with the cam part of upwards sliding for the pushing tow brake silpper; Be positioned at and also be equipped with a un-brake pedal that is used for brake off on the castor body frame of brake pedal top, the drive end of described un-brake pedal can stretch into the slotted eye of brake silpper upper lateral part and cooperate with brake pedal, is provided with first retracing spring be used to the un-brake pedal that resets between the last perforation of described un-brake pedal and castor body frame.In brief, the castor body frame is provided with for brake pedal and two pedals of un-brake pedal, described two pedals place the same side of castor body frame, step on brake pedal downwards, the un-brake pedal is stepped in castor generation full application of brake downwards, castor is removed full application of brake, recover full free state, i.e. two kinds of operations all are to finish the castor braking and remove the control of braking by the stressed of equidirectional, namely adopt the stressed in the same way operation mode that acts on the fulcrum two ends.Drive brake silpper by brake pedal castor is carried out brake operating; Driving brake pedal and brake silpper by the un-brake pedal resets castor is carried out the brake off operation.
Further, the above-mentioned sidewall of going up perforation has for the rail groove of guiding and navigation groove, the extension conduit that described navigation groove is rail groove, and the respective sides of described un-brake pedal is provided with the guide rail column that cooperates with guide groove and the locating dowel pin that cooperates with the navigation groove.In other words, in body frame laterally disposed rail groove is arranged, be used for the brake off pedal is installed, rail groove has limited the sense of motion of pedal, namely can only be downwards with reset, left-right and front-back can not take place to be rocked.Between rail groove and releasing pedal, be provided with first retracing spring, be used for pedal resetting after operation.By a locating dowel pin, pass body frame and the guide rail column of removing pedal, the releasing pedal can only be moved in body frame navigates the groove zone, be used for the stroke of control brake off, avoid removing pedal and cause losing efficacy because interfere with inner miscellaneous part.
Further, above-mentioned fan-shaped braking tooth bar is arranged on the both sides side lower part of brake silpper.Be disposed with universal spragging gear, bearing and mainshaft cap from bottom to top in the versatile spindle bearing of described castor body frame, the upper lateral part of described brake silpper also is provided with for cooperating with spragging gear, in order to the tooth-strip part of its universal rotation of braking.Described brake silpper upper lateral part also is provided with the guide pillar that resets, and described second retracing spring is nested with in the outside that resets guide pillar.Be arranged at intervals be used to the buckle that buckles on the castor body frame the corresponding draw-in groove that is provided with bayonet fitting on the described castor body frame on the described side cover.
The beneficial effects of the utility model are: (1) has changed traditional single step wheel by the operating mode of not stressed in the same way braking and un-brake, the control of use two pedal, make foot be subjected to force direction identical to pedal, step on brake pedal then castor braking can not move, step on remove pedal then castor brake off state can move flexibly, the realization two pedal is controlled in the same way, uses flexible, convenient; (2) use the rolling member of import material to cooperate with high-grade plastic material, allow the more smooth and easy nothing of cooperation between each parts interfere, freely turn to and walking freely.
