Specific embodiment
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
As Figure 1-4, the present embodiment provides a kind of rotary apparatuss, including can relatively rotate and turning of being coaxially disposed
Dynamic portion 1 and fixed part 2, the fixed part 2 includes lower half 21 and the first half 22, and the lower half 21 is to be provided with depression
The tabular of chamber, the first half 22 is the ring-type covered on the lower half 21, and the rotation section is installed on the caveli
It is indoor.
Some running rollers 3 are provided between the rotation section 1 and the fixed part 2, the running roller 3 supports the rotation section
1 and when the rotation section 1 relatively rotates with the fixed part 2 running roller 3 can the rotation section 1 effect (rolling
Dynamic friction) under rotation.As shown in Fig. 2 the running roller 3 includes roll shaft 31 and wheel disc 32, the running roller 3 is located at the first half
Between 22 and lower half 21, the top and bottom of the roll shaft 31 are inserted respectively into and be located at respectively the first half 22 and lower half
In 21 axis holes 20.
The first half 22 is fixed with the lower half 21 by lock screw 4, so as to the running roller 3 is held on into the two
Between.
Prolong the groove 11 for circumferentially offering that section is triangle on the periphery wall of the rotation section 1, the wheel disc 31 sets
Being equipped with can enter the groove 11 and the peripheral portion being engaged with the structure of the groove 11, as shown in Figure 2,3, 4, institute
It is substantially in top in shape to state running roller 3.Certainly, the part that the wheel disc 31 is entered in groove can also be spheric or cylinder
Shape, but the above-mentioned optimal way of the present embodiment can provide more preferable support force for spheric, relative to cylinder
For structural strength it is higher, edge not easy fracture.
On the fixed part 2, specifically on the lower half 21, tight lock part 5 is provided with, the tight lock part 5 is by turning
Axle 211 is installed on the fixed part 2.The tight lock part 5 includes the plectane portion 51 with breach 511, and is connected to the circle
Spanner 52 in plate portion, the plectane portion 51 is located at the radial outside of the rotation section 1, sets on the periphery wall of the rotation section 1
It is equipped with some arc slots to make way 12；Make arbitrary slot to make way 12 nearest apart from the plectane portion 51 when the rotation section 1 is rotated
When, can rotate the plectane portion 51 makes the non-gap position in the plectane portion 51 be at least partially into the slot to make way 12, from
And locking the rotation section 1 prevents it from rotating relative to fixed part 2；When rotate the plectane portion 51 make the breach 511 away from
From the rotation section 1 it is nearest when, the rotation section 1 can rotate relative to the fixed part 2.
So that the slot to make way is two and two slots to make way are set at 90 ° intervals as an example, as shown in Figure 5 (for convenience
Show, Fig. 5-8 is the schematic diagram for removing the first half 22 under vertical view state), lock at this first on station, the circle
The non-gap position of plate portion 51 is partly into in a slot to make way 12, and now rotation section 1 cannot rotate.Such as Fig. 6
It is shown, slewing circle plate portion 51 make the breach 511 apart from the rotation section 1 it is nearest when, now the rotation section 1 can be relative to
The fixed part 2 is rotated.As shown in fig. 7, clockwise the rotation section 1 is rotated into 90 °, so as to reach the second locking
On station, now another slot to make way 12 is nearest apart from the plectane portion 51.As shown in figure 8, slewing circle plate portion 51, makes plectane portion
Being partly in the slot to make way 12 for 51 non-gap position, completes again the locking to rotation section 1.
The edge of the breach 511 can be arc.
The lower surface of the rotation section 1 is provided with least one stopper slot 13 opened up along arching trajectory, the arc
The center of circle of shape track is on the axis of the rotation section 1；The lower half 21 is provided with what is be engaged with the stopper slot 13
Limited post 212；The radian of the arching trajectory is 90 °.
Telltale mark 221 is provided with the top surface of the first half 22, on the top surface of the rotation section 1 two are provided with
Individual cue mark 14, when arbitrary cue mark 14 is directed at the telltale mark 221, one of two described slots to make way 13 be located at away from
From the proximal most position of plectane portion 51.
Using above-mentioned technical proposal, the rotary apparatuss of the present invention, it is provided between the rotation section and the fixed part
Some running rollers, when the rotation section rotates against with the fixed part, can be in rotation section by the rotation of some running rollers
Uniform frictional force is provided in circumference, it is ensured that the rotation of rotation section is steady；Can be turned in rotation section by tight lock part specified
Locked during position, and the structure of tight lock part is relatively simple, it is easy to operate.
In order to reach material-saving, mitigate the purpose of weight, can also offer in the lower surface of the rotation section 1 some
Lightening grooves 909, as shown in Figure 9.
Further, as shown in Figure 10, it is additionally provided with the lower half 21 for supporting the multiple of the rotation section 1
Curved support bar 908, multiple curved support bars 908 are concentric to be arranged and is uniformly distributed in the circumferential.By support bar
908 setting, can play a part of support rotating portion 1, while rotation section 1 and the bump contact of lower half 21 are avoided, because
This being capable of less friction.The curved support bar 908 can add glass fiber material to make by nylon, with good wear-resisting effect
Really.
As shown in figure 11, further, the lower surface in the lower half 21 is provided with the attacker 907 of some recess shapes and ties
Structure, is easy to hand-held.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of embodiment.For
For those of ordinary skill in the art, the change or change of other multi-forms can also be made on the basis of the above description
It is dynamic.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or change
Among moving still in the protection domain of the invention.
