Specific embodiment
For that can further appreciate that the feature of the utility model, technological means and the specific purposes reached, function, below
The utility model is described in further detail with specific embodiment with reference to attached drawing.
Referring to figs. 1 to Fig. 4.
The utility model embodiment discloses a kind of universal wheel, including bottom plate 1, stent 2, idler wheel 3, stent 2 be rotatably connected in
1 lower section of bottom plate, idler wheel 3 are rotatably dispose on stent 2, and 1 top of bottom plate is provided with brake assemblies 4, and brake assemblies 4 are included the bottom of through
Plate 1 and be slidably connected with bottom plate 1 brake lever 41, be fixedly connected on the position plate 42 of 41 one side of brake lever, be fixedly connected on branch
The snap-gauge 43 of 2 one side of frame is fixedly connected with several orientation blocks 421 on position plate 42, is provided through on snap-gauge 43 and orientation block
421 matched spacing breach 431；Reset assembly 5 is provided in brake lever 41, reset assembly 5 includes being fixedly connected on brake
The top plate 51 of 41 one side of bar, the reset cylinder 52 for being sleeved in brake lever 41 and being fixedly connected with 1 top of bottom plate are fixedly connected on brake
41 one side fixture block 53 of bar resets and card hole 521 with 53 form fit of fixture block is provided through on cylinder 52, in brake lever 41 and is located at
53 opposite side of fixture block is fixedly connected with the spring A54 to offset with resetting cylinder 52, and fixture block 53 is stretched under the elastic force effect of spring A54
Go out card hole 521,1 top of bottom plate is provided with the spring B 55 to offset with 51 bottom of top plate.
Concrete operations principle is, when needing brake orientation, depresses brake lever 41, brake lever 41 is transported downwards along bottom plate 1
It is dynamic, in 41 motion process of brake lever fixture block 53, spring A54 will be driven to be moved down along 52 inner wall of cylinder is resetted.When fixture block 53 moves
When moving 521 position of card hole, fixture block 53 will be combined by the thrust of spring A54 with card hole 521, and final fixture block 53 stretches out card hole 521
And 41 position of brake lever is fixed.At this point, position plate 42 is in contact with snap-gauge 43, orientation block 421 and spacing breach are realized
431 combination, the rotation of stent 2 will be restricted, and at the same time, 41 bottom of brake lever is contacted with 3 surface of idler wheel, idler wheel 3
By stop under the action of frictional force.The pushing of brake lever 41 realizes the brake to idler wheel 3 and the steering locking to stent 2,
Convenience greatly improves.When needing to discharge brake and release direction-locking, press fixture block 53 and retract in reset cylinder 52, brake
Bar 41 will move upwards under the elastic force effect of spring B 55, and brake lever 41 will drive fixture block 53 and spring A54 to moving up at this time
It is dynamic, and finally resetted under the elastic force effect of spring B 55.At this point, 3 surface of idler wheel is left in 41 bottom of brake lever, brake is released,
Position plate 42 is separated with snap-gauge 43 simultaneously, and the direction-locking of stent 2 is released from.
In order to realize comprehensive orientating function, based on above-described embodiment, position plate 42 is plectane, orientation block 421 for etc.
Divide the square plate being vertically arranged on position plate 42,43 one side of snap-gauge is arranged to and 42 matched circular arc of position plate, spacing breach
431 are arranged to the square breach coordinated with orientation block 421.Position plate 42 is arranged to plectane, and decile is set vertically on plectane
Put square orientation block 421, by 43 one side of snap-gauge be arranged to 42 matched circular arc of position plate, no matter stent 2 turns to arbitrarily
Angle, when pushing brake lever 41, position plate 42 can be contacted with snap-gauge 43, realize orientation block 421 and spacing breach 431
Combination, so as to fulfill the direction-locking to stent 2.
In order to promote braking effect, based on above-described embodiment, 41 bottom of brake lever is spheroidal.41 bottom of brake lever is set
It is set to spheroidal, when brake, 41 bottom down-pressure roller 3 of brake lever, 41 bottom of brake lever of spheroidal, which will sink into, to be become
3 surface of idler wheel of shape forms the brake weight of bigger, promotes braking effect.
Based on above-described embodiment, bottom plate 1 is provided through several mounting holes 11.The mounting hole 11 being arranged on bottom plate 1, side
Just this universal wheel is assembled.
Based on above-described embodiment, brake lever 41, which is stretched out, resets 52 top of cylinder, and 41 top of brake lever, which is fixedly connected with, cuts somebody's hair
411.Be arranged on 41 top of brake lever cuts somebody's hair 411, improves the convenience for pushing brake lever 41, while can prevent brake lever 41
It pushes excessively, causes the damage of brake lever 41.
Above example only expresses a kind of embodiment of the utility model, and description is more specific and detailed, but not
Can the limitation to the utility model patent scope therefore be interpreted as.It should be pointed out that the ordinary skill people for this field
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With new protection domain.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
