Abstract
The utility model provides a plastic caster wheel, a wheel is pivoted on a down end of a support, an upper end of the support is sleeved outside a bearing outer ring, a bearing inner ring is equipped with a shaft lever, a braking handle is hinged to one side of the support. A brake pad is fixed to an inner side of the support by a pin, one end of the brake pad locates below the bearing, the other end of the brake pad locates below the braking handle. The plastic caster wheel has characteristics that: an upper gear ring is arranged below the bearing, and the upper gear ring is fixed to an inner ring of the bearing. One end of the brake pad located below the bearing is a back end of the brake pad, the back end of the brake pad has a down gear ring. The upper and down gear rings are opened with gear teeth which are arranged in periphery of the gear ring, the upper gear ring is engaged with the down gear ring. An upper surface of the front end of the brake pad has one or two flutes. A down surface of the front end of the brake pad has bulged. Producing the plastic caster wheel has few working procedures, the upper gear ring and the down gear ring are opened with gear teeth in periphery evenly, which does not accurate locating, only needs the upper gear ring and the down gear ring staggered one gear difference to brake the caster wheel by stepping on the braking handle.
Description
Technical field
The utility model relates to a kind of castor, particularly a kind of plastics castor.
Background technology
Existing domestic use caster wheel mostly is iron, and its support and part are iron.It is more that the plastics castor uses abroad, is plastics and makes except that bearing and footstalk.Plastics castor good looking appearance, and be difficult for getting rusty.Because the difference of material structurally there are differences plastics castor and iron castor, and the general part of iron castor Fabrication procedure wants about 20 roads, and a part just needs several procedures, and production process is various, the flowing water line length, then production process is few to adopt the plastic stent caster wheel.Existing plastics castor since brake structure, just can step on brake handle when needing the longitudinal axis of the working direction of wheel and brake facing consistent wheel is fixed, the precision that requirement aligns is very high.
Summary of the invention
The utility model provides a kind of plastics castor, and purpose is to solve the prior art problem, and providing a kind of does not need accurately to position when brake, can step on brake handle castor is checked caster wheel.
The utility model technical scheme that adopts of dealing with problems is:
The plastics castor, the support lower ending pivot is provided with wheel, and the support upper end is set in outside the outside race, is arranged with axostylus axostyle in the bearing inner ring, and brake handle is hinged on support one side.Brake facing is fixed on the support inboard by bearing pin, and its brake facing one end is positioned at the bearing below, and the other end is positioned at the brake handle below.Bearing below is provided with upper ring gear, and upper ring gear is fixed together with the bearing inner ring, and upper ring gear has downward teeth, and described teeth evenly are opened in one week of upper ring gear.The end that brake facing is positioned at bearing below is the brake facing rear end, and the brake facing rear end has lower ring gear, and lower ring gear has teeth upwards, and described teeth evenly are opened in one week of lower ring gear, and upper ring gear and lower ring gear can be meshing with each other.Brake facing front end upper surface has groove.
Brake facing front end upper surface has one or two groove.
The lower surface of brake facing front end has several projectioies.
The beneficial effects of the utility model: plastic foot wheel production process is few, and the upper ring gear of this castor and lower ring gear all evenly have teeth in one week, when brake, do not need accurately to position, castor is checked as long as the tooth difference that upward staggers between the lower ring gear can be stepped on brake handle.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the plastics castor, support 1 lower ending pivot is provided with wheel 2, and support 1 upper end is set in outside bearing 3 outer rings, is arranged with axostylus axostyle 4 in bearing 3 inner rings, and brake handle 8 is hinged on support 1 one sides.Brake facing 7 is fixed on support 1 inboard by bearing pin, and its brake facing 7 one ends are positioned at bearing 3 belows, and the other end is positioned at brake handle 8 belows.The end that brake facing 7 is positioned at bearing 3 belows is brake facing 7 rear ends, and brake facing 7 rear ends have lower ring gear 6, and lower ring gear 6 has teeth 61 upwards, and described teeth 61 evenly are opened in 6 one weeks of lower ring gear.Bearing 3 belows are provided with upper ring gear 5, and upper ring gear 5 is fixed together with bearing 3 inner rings, and upper ring gear 5 has downward teeth 51, and described teeth 51 evenly are opened in 5 one weeks of upper ring gear, and upper ring gear 5 and lower ring gear 6 can be meshing with each other.Brake facing 7 front end upper surfaces have a groove 71, and when castor was in braking state, brake handle 8 was stuck in this groove 71, and brake handle 8 is fixed.The lower surface 70 of brake facing 7 front ends has several projectioies 73.
As shown in Figure 5, when brake, depress brake handle 8, brake handle 8 cws rotate.Brake facing 7 front ends also were pressed downward when brake handle 8 pressed down, brake facing 7 clockwise rotates around bearing pin, tilt upward in its rear end, lower ring gear 6 on brake facing 7 rear ends is meshed together with the upper ring gear 5 that is fixed on bearing 3, and the tooth that need stagger mutually when upper ring gear 5 and lower ring gear 6 engagements is poor.Brake handle 8 is stuck on the groove 71 of brake facing 7 front ends, this moment, the lower surface 70 of brake facing 7 front ends was pressed against on the wheel 2, with wheel 2 fixing can not moving ahead, owing to being meshing with each other with lower ring gear 6, upper ring gear 5 is in the same place simultaneously, support 1 can not be rotated around bearing axis, so the direction of wheel 2 also is fixed.The lower surface 70 of brake facing 7 front ends has several projectioies 73, and the resistance when this projection 73 has increased brake can better be checked castor, the safety when having improved its use.
Structural representation as shown in Figure 6, in this third gear castor the caster wheel structure except that brake facing 7 ' structure with different among the embodiment 1, other structure is with all identical.Brake facing 7 ' structure among the embodiment 2 as shown in Figure 7, brake facing 7 ' front end have two grooves 71 ', 72 ', when 71 ' time of brake handle 8 ' be stuck in groove, since this moment brake facing 7 ' front end lower surface 70 ' be not pressed against wheel 2 ' on, wheel 2 ' can continue to move ahead, but because upper ring gear 5 ' is meshing with each other with lower ring gear 6 ' and is in the same place, support 1 ' can not be rotated around bearing axis, therefore at this moment castor be in can only be along straightaway braking state.Continue to depress brake handle 8 ', 72 ' time of brake handle 8 ' be stuck in groove, this moment brake facing 7 ' front end lower surface 70 ' be pressed against wheel 2 ' on, with wheel 2 ' check and to move ahead, owing to being meshing with each other with lower ring gear 6 ', upper ring gear 5 ' is in the same place simultaneously, support 1 ' can not be rotated around bearing axis, so wheel 2 ' direction also be fixed, this moment, castor was in direction and wheel 2 ' motionless braking state all is fixed.
Plastic foot wheel production process is few, and the upper ring gear of this castor and lower ring gear all evenly have teeth in one week, does not need accurately to position when brake, can step on brake handle castor is checked as long as go up the tooth difference that staggers between the lower ring gear.
