Detailed description of the invention
Embodiment one: as shown in accompanying drawing 1-accompanying drawing 10, a kind of rotary joint, the second end cap 21 comprising the first end cap 11, be rotationally connected by the first axle 41 with the first end cap 11, first end cap 11 is provided with the first fluted disc 12, second end cap 21 is provided with the second fluted disc 22, first fluted disc 12 is fixed on the first end cap 11, and the second fluted disc 22 only can be slidably arranged on the second end cap 21 along the direction of axis line of the first axle 41.
As shown in accompanying drawing 5-accompanying drawing 10, a sidepiece on first fluted disc 12 has the first gear ring 13 be made up of helical teeth, one sidepiece of the second fluted disc 22 has the second gear ring 23 be made up of helical teeth, rotary joint also comprises can rotate and the rotational slide block 31 slided around the first axle 41, and rotational slide block 31 is between the first fluted disc 12 and the second fluted disc 22.
Rotational slide block 31 offers the first groove 32 and the second groove 33, first groove 32 is adjacent with the second groove 33, and the first groove 32 is deeper than the second groove 33, first fluted disc 12 has the lug boss 14 that can close with the first groove 32 or the second groove 33 phase inserting, second groove 33 is consistent with the direction of tilt of the tooth on the second gear ring 23 relative to the position distribution of the first groove 32, namely which rolls tiltedly the teeth directional on the second gear ring 23, and namely the second groove 33 is positioned at which side of the first groove 32.
Rotary joint has latched position and unlocked position, as shown in Figure 9, under rotary joint is in latched position, first gear ring 13 is meshed with the second gear ring 23, and lug boss 14 is inserted in the first groove 32, as shown in Figure 10, when rotary joint is in the unlocked position down, first gear ring 13 and the second gear ring 23 are separated, and lug boss 14 inserts in the second groove 33
The rotating and limiting mechanism of the rotational angle range limiting relative first axle 41 of rotational slide block 31 is provided with between rotational slide block 31 with the second fluted disc 22,
Rotary joint also comprises the first fluted disc 12 can be made to be meshed with the second fluted disc 22 stable and simultaneously lug boss 14 and the first groove 32 or close stable elastic component 51 with the second groove 33 phase inserting.
In the present embodiment, elastic component 51 is arranged between the second fluted disc 22 and the second end cap 21.Elastic component 51 can also be arranged between the second fluted disc 22 and the first axle 41.
As shown in Figure 6, about the mounting structure of the second fluted disc 22, the second end cap 21 has on guide groove 24, second fluted disc 22 that length extends along the direction of axis line of the first axle 41 and have guiding convex tendon 25, guiding convex tendon 25 is inserted in guide groove 24.
Rotational slide block 31 is positioned at the second gear ring 23.
Rotating and limiting mechanism comprises and is arranged on first on the second fluted disc 22 protruding 26 and the second projection 27, is arranged on the 3rd projection the 34, three projection 34 on the first fluted disc 12 between the first projection 26 and the second projection 27.As shown in Figure 7, rotary joint is when unidirectional rotation when rotating and limiting mechanism is to end position, and the 3rd protruding 34 is protruding 27 inconsistent with second, as shown in Figure 8, when rotating and limiting mechanism is to end position during revolution, the 3rd protruding 34 and first projection 26 inconsistent.
When under the state of rotary joint at Fig. 1, as shown in Figure 9, under being in latched position, lug boss 14 is inserted in the first groove 32, and the first gear ring 13 is meshed with the second gear ring 23.First fluted disc 11 can only pull rotation according to Fig. 2 direction of arrow due to the unidirectional tooth in inclined-plane.As shown in Figure 2, rotary joint is under latched position, first end cap 11 can only along relative second end cap 21 unidirectional rotation of the direction of arrow, first gear ring 13 and the second gear ring 23 often a mobile tooth position are angle gears, under the elastic force of elastic component 51, the first fluted disc 12 driven rotary sliding shoe 31 rotates, under rotating to position shown in Fig. 2, Fig. 7 relative to the second fluted disc 22,3rd protruding 34 is inconsistent with the second projection 27, and rotational slide block 31 can not rotate relative to the second fluted disc 22 again.As shown in Figure 3, first end cap 11 is continued rotate by arrow relative to the second end cap 21, lug boss 14 now on the first fluted disc 12 pushes rotational slide block 31 by the inclined-plane in the first groove 32 on rotational slide block 31 and slides, until, as shown in Figure 10, lug boss 14 falls into the second groove 33 li, and now the first gear ring separates mutually with the second gear ring.First end cap 11 now can rotate revolution as Fig. 4 direction of arrow, and lug boss 14 rotational slide block 31 rotates simultaneously, and rotate to as shown in Figure 8, now the 3rd projection 34 has encountered the first projection 26, and rotational slide block 31 can not rotate relative to the second fluted disc 22 again.Now, when the first end cap 11 continues to rotate, the lug boss 14 now on the first end cap 11 is pushed by the inclined-plane of rotational slide block 31 second groove 33 thus drops in the first groove 32.Now the first end cap 11 is in Fig. 1 state.
Embodiment two, as shown in accompanying drawing 11, accompanying drawing 12, embodiment two is with the difference of embodiment one: together with the second fluted disc 22 fixes with the second end cap 21, can not slide, therefore rotary joint is under latched position is converted to unlocked position, second end cap 21 can move axially by relative first axle 41, and elastic component 51 is arranged between the second fluted disc 22 and the first axle 41, is namely arranged between the second end cap 21 and the first axle 41.
A kind of perambulator, adopt above-mentioned rotary joint, be convenient to user and adjust angle needs between the first rod member and the second rod member, perambulator comprises the first rod member, the second rod member, first end cap 11 is fixed on an end of the first rod member, and the second end cap 21 is fixed on an end of the second rod member.
As mentioned above, we are illustrated according to aim of the present invention completely, but the present invention is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present invention.
