Description
The utility model relates to a kind of castor, relates in particular to the two braking of a kind of single-wheel universal caster wheel.
Castor is a kind of mechanical component commonly used in various fields such as commercial production, scientific research, business management, medical industry and daily life.The castor industry is when the lower bead tile of design castor vertical rotation shaft is fitted to each other part at present, mostly adopt press or the reversing sense nut locking after the technology that presses again, the shortcoming of this mounting structure is: precision is low, parts easily deform, anti-loosening weak effect, and service life is short.Also have, what the brake equipment of single-wheel universal caster wheel adopted in the prior art is the compressing friction type, promptly realize braking by mechanical pressure castor surface, this brake structure has two big shortcomings: the one, and wheel surface and brake equipment direct contact cause the wearing and tearing of wheel surface, thereby have shortened the service life of wheel body; The 2nd, its braking effect is unidirectional, and it can only control the rolling before and after the wheel body, can not prevent the rotation that is subjected to after the external force in the original place.
The purpose of this utility model is exactly in order to overcome the above-mentioned shortcoming of prior art, a kind of technology assembly precision height, anti-loosening effective to be provided, have the bi-directional braking function simultaneously, the two braking of the single-wheel universal caster wheel that the little life-span of wearing and tearing is long.
Below, the accompanying drawings the technical solution of the utility model.

The utility model caster wheel is achieved in that
The basic structure of the utility model single-wheel universal caster wheel comprises rotation screw thread vertical shaft 1, swinging strut 14, central, transverse axis 15 and wheel body 6, and wherein the top of swinging strut 14 links with rotation screw thread vertical shaft 1, swinging strut 14 bottoms and central, transverse axis 15 and the wheel body 6 that can pivot link.The assembling of its top screw thread vertical shaft and structural relation can be referring to Fig. 3: the nut end of rotation screw thread vertical shaft 1 down, thread end passes lower bead tile 5 from bottom to top successively, the top of swinging strut 14, screw in and pass upper bead tile 4, joining sufficient ball simultaneously joins the three together, again from thread end screw in nut 2 with pearl watt 4 back ofs the body tightly on screw thread vertical shaft 1, then will and the annular spaces of upper bead tile 4 and nut 2 be close-fitting shackle 3 and be pressed between this annular spaces, central, transverse axis 15 is passed the axis hole 16 of swinging strut 14 1 sides successively, the axis hole 16 of the opposite side of wheel body 6 and swinging strut 14.
In order to realize two braking functions, the utility model can also comprise the bidirectional braking device that is made of driving parts, wheel body braking component, vertical shaft braking component.Wherein driving parts comprises brake pedal 9 and braking press strip 8, and the wheel body braking component comprises braking fixedly ring gear 10 and braking ratchet 12, and the vertical shaft braking component comprises braking clutch-plate 13, the upright tooth 20 in lower bead tile lower surface.
Above-mentioned two brake equipments can be realized like this, brake pedal 9 and braking press strip 8 and swinging strut 14 are coaxial and passed successively from outside to inside by central, transverse axis 15, the axis hole 16 of the axis hole of brake pedal 9 and swinging strut 14 can serve as the axle motion with central, transverse axis 15 with footpath, brake pedal 9, and the lateral length of braking press strip 8 axis holes equates with shaft hole diameter 16, longitudinal length can be made the up-and-down movement with respect to central, transverse axis 15 greater than internal diameter, the braking press strip 8 of axis hole 16.
There are two to place brake pedal both sides and Shen baffle plate 8a, 8b laterally about in the of 9 respectively on the above-mentioned braking press strip 8, when brake pedal 9 serves as the axle motion with central, transverse axis 15, braking press strip 8 is with being braked baffle plate 8a, the 8b up-and-down movement that pedal 9 is stirred, on braking press strip 8, also have respectively the Shen advance the perforate up and down 17,18 of swinging strut 14 sidewalls, and thereupon up-and-down movement dial bar 19 and braking ratchet 12;
Above-mentioned braking fixedly ring gear 10 is fixed on the wheel body 6 a side near brake equipment, and when braking press strip 8 moved downward, braking ratchet 12 can tightly fasten fixedly ring gear 10.
Above-mentioned braking clutch-plate 13 is that axle mounting is on the top of swinging strut 14, between the outside of the wheel body above central, transverse axis 15 vertical lines and swinging strut inboard with pin 11, one end of braking clutch-plate 13 is close to the bottom of dialling bar 19, and the other end is converted into the between cog of briar tooth 21 Shens to the upright tooth 20 in lower bead tile lower surface.
The two braking of single-wheel of the present utility model universal caster wheel is at the needs glancing impact, as long as one end of brake pedal 9 is stepped on to next with pin, the baffle plate 8a that brake pedal 9 will be stirred braking press strip 8 bottoms makes braking press strip 8 move down, so the braking ratchet 12 that perforate 18 under swinging strut 14 sidewalls is advanced in braking press strip 8 top Shens just tightly is buckled in the fixedly between cog of ring gear 10, reaches the effect that wheel body is rolled and brakes; Meanwhile, Shens advance that the bar 19 of dialling of perforate 17 also moves downward synchronously on swinging strut 14 sidewalls above the braking press strip 8, dialling bar 19 drives braking clutch-plates 13 and presses close to its end and also move downward, and the briar tooth 21 of braking clutch-plate 13 other ends serve as axially to go up between cog that motion, Shen advance the upright tooth 20 in lower bead tile lower surface to form and mesh with pin 11, reaches the effect of double thread vertical shaft rotation brake.When needing brake off, as long as step on to next at the other end of brake pedal 9 with pin, two braking points break away from immediately up and down, and the two braking of single-wheel universal caster wheel recovers the state freely that moves again.
In order to make rotating part of the present utility model have better lubricity, reach the effect of rotating flexibly, increasing the service life, braking of the present utility model is ring gear 10, upper bead tile 4, lower bead tile 5, nut 2, shackle 3 fixedly, and the bearing outside of wheel body can be formed by powder metallurgy pressing.Except lubricity was good, parts geometric accuracy that these powder metallurgy pressing form and row position tolerance were also very high, and this has also played great role for improving whole running accuracy and pressure resistance of the present utility model.
In addition, the utility model wheel body bearing can adopt the needle bearing that has the nylon retainer, and its carrying is big, noise is low, the rotation flexibility and reliability.Wheel hub of the present utility model can adopt the injection mo(u)lding of ABS engineering plastics, and it has the intensity height, bearing capacity is strong.Withstanding corrosion, the characteristics that outward appearance is good.Outer rim of the present utility model can adopt polyurethane elastomer, and its physical and mechanical properties, particularly abrasion test all are better than other rubber greatly.
The utility model can be widely used in various mobile furniture, various mobile office equipment, various mobile industrial equipment, various ambulatory medical device, various mobile research equipments or the like.Because its uniqueness, good loosing prevention, shock resistance, unique, stable bi-directional braking performance, and above-mentioned other premium properties, so the utility model is particularly suitable for configuration in various high-grade medicine equipments and various high-grade scientific research apparatus unwheeling, uses.
