Abstract

Provided are a rotational joint and a baby carrier. When the protruding portion of the rotational joint is inserted in a first groove, a first end cover and a second end cover can carry out unidirectional rotation, and the rotation range of the first end cover and the second end cover is controlled through a rotation limiting mechanism. In a unidirectional rotating process, under the action of an elastic piece, a rotating sliding block rotates together along with the first end cover. When the unidirectional rotation is carried out and the rotation limiting mechanism reaches a limiting position, the first end cover and the second end cover continue to be rotated, the protruding portion is made to be inserted in a second groove, the rotating sliding block slides in the axial direction of a first shaft, therefore, a second fluted disc is driven to slide in the axial direction of the first shaft, a first gear ring and a second gear ring are made to be separated, the first end cover and the second end cover can be turned back, and when the rotating limiting mechanism reaches the limiting position in a turning back process, the first end cover and the second end cover continue to be turned back, the protruding portion is made to be inserted in the first groove, the first gear ring and the second gear ring are meshed with each other again, and an angle can be adjusted in a unidirectional mode, and the rotational joint and the baby carrier are convenient to use.

The specific embodiment
Embodiment one: shown in accompanying drawing 1-accompanying drawing 10, a kind of rotary joint, comprise first end cap 11, with first end cap 11 by first 41 second end cap 21 that is rotationally connected, first end cap 11 is provided with first fluted disc 12, second end cap 21 is provided with second fluted disc 22, first fluted disc 12 is fixed on first end cap 11, and second fluted disc 22 only can be slidingly arranged in along first 41 direction of axis line on second end cap 21.
Shown in accompanying drawing 5-accompanying drawing 10, has first gear ring 13 that is constituted by helical teeth on the sidepiece on first fluted disc 12, has second gear ring 23 that is constituted by helical teeth on one sidepiece of second fluted disc 22, rotary joint also comprises can be around first 41 rotational slide piece 31 that rotates and slide, and rotational slide piece 31 is between first fluted disc 12 and second fluted disc 22.
Offer first groove 32 and second groove 33 on the rotational slide piece 31, first groove 32 is adjacent with second groove 33, and first groove 32 is deeper than second groove 33, has the lug boss 14 that can close with first groove 32 or the 33 phase insertings of second groove on first fluted disc 12, second groove 33 is consistent with respect to the direction of tilt of the tooth on the position distribution of first groove 32 and second gear ring 23, i.e. which inclination of teeth directional on second gear ring 23 is oblique, and second groove 33 namely is positioned at which side of first groove 32.
Rotary joint has latched position and unlocked position, as shown in Figure 9, when lockout mechanism is under the latched position, first gear ring 13 is meshed with second gear ring 23, and lug boss 14 is inserted in first groove 32, as shown in Figure 10, when lockout mechanism is in the unlocked position down, first gear ring 13 and second gear ring 23 are separated, and lug boss 14 inserts in second groove 33
Be provided with the rotating and limiting mechanism of relative first 41 rotational angle range of restriction rotational slide piece 31 between rotational slide tooth piece 31 and second fluted disc 22,
Rotary joint also comprises can make the fluted disc 12 of winning be meshed stable with second fluted disc 22 and simultaneously lug boss 14 and first groove 32 or close stable elastic component 51 with the 33 phase insertings of second groove.
In the present embodiment, elastic component 51 is arranged between second fluted disc 22 and second end cap 21.Elastic component 51 can also be arranged between second fluted disc 22 and first 41.
As shown in Figure 6, about the mounting structure of second fluted disc 22, have length on second end cap 21 and have guiding convex tendon 25 on guide groove 24, the second fluted discs 22 of first 41 direction of axis line extension, guiding convex tendon 25 is inserted in the guide groove 24.
Rotational slide piece 31 is positioned at second gear ring 23.
Rotating and limiting mechanism comprises and is arranged on first on second fluted disc 22 projection, 26 and second projection 27, is arranged on the 3rd projection 34, the three projectioies 34 on first fluted disc 12 between first protruding 26 and second projection 27.As shown in Figure 7, rotary joint is worked as rotating and limiting mechanism to end position when unidirectional rotation, and the 3rd projection 34 and second projection 27 is inconsistent, as shown in Figure 8, works as rotating and limiting mechanism during revolution to end position, and the 3rd projection 34 and first protruding 26 is inconsistent.
Under the state of rotary joint at Fig. 1, as shown in Figure 9, be under the latched position, lug boss 14 is inserted in first groove 32, and first gear ring 13 is meshed with second gear ring 23.First fluted disc 11 is because the unidirectional tooth in inclined-plane can only be pulled rotation according to Fig. 2 direction of arrow.As shown in Figure 2, rotary joint is under latched position, first end cap 11 can only be along relative second end cap of the direction of arrow 21 unidirectional rotation, first gear ring 13 and tooth position of second gear ring, 23 every movements are angle gears, under the elastic force of elastic component 51,22 rotations of first fluted disc, 12 driven rotary sliding shoes, 31 relative second fluted discs are when rotating under Fig. 2, the position shown in Figure 7, the 3rd projection 34 and second projection 27 is inconsistent, and rotational slide piece 31 can not rotate relative to second fluted disc 22 again.As shown in Figure 3, first end cap 11 is continued relative second end cap 21 press the arrow rotation, lug boss 14 on first fluted disc 12 pushes 31 slips of rotational slide piece by the inclined-planes in first groove 32 on the rotational slide piece 31 at this moment, until, as shown in figure 10, lug boss 14 falls into 33 li of second grooves, and this moment, first gear ring separated mutually with second gear ring.First end cap 11 this moments can be as Fig. 4 direction of arrow rotation revolution, and 31 rotations of lug boss 14 rotational slide pieces rotate to as shown in Figure 8 simultaneously, and this moment, the 3rd projection 34 was run into first projection 26, and rotational slide piece 31 can not rotate with respect to second fluted disc 22 again.At this moment, when first end cap 11 continues rotation, thereby the inclined-plane of the lug boss 14 on this moment first end cap 11 by rotational slide piece 31 second grooves 33 pushes and drops in first groove 32.This moment, first end cap 11 was in Fig. 1 state.
Embodiment two, shown in accompanying drawing 11, accompanying drawing 12, embodiment two is with the difference of embodiment one: second fluted disc 22 and second end cap 21 fix together, can not slide, therefore rotary joint is under latched position is converted to unlocked position, second end cap 21 can relative first 41 moves axially, and elastic component 51 is arranged between second fluted disc 22 and first 41, namely is arranged between second end cap 21 and first 41.
A kind of perambulator, adopt above-mentioned rotary joint, be convenient to the user and adjust angle needs between first rod member and second rod member, perambulator comprises first rod member, second rod member, first end cap 11 is fixed in an end of first rod member, and second end cap 21 is fixed in an end of second rod member.
As mentioned above, we are illustrated according to aim of the present utility model fully, but the utility model is not limited to above-described embodiment and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought permission of the present utility model.
