Embodiment
Shown in Figure 1, revolute joint of the present utility model comprises the first bustle pipe 101 being rotatably connected between inside, the second bustle pipe 102, two bustle pipes are movably connected by a joint shell 17, the left and right, side of joint shell 17 respectively offers a restraining groove 14 and a lock pin qualifying bit groove 16, and coordinate the first lock pin 131 to be connected with 122 with the pivot 121 of two bustle pipes with the 4th lock pin 134 by two pin-and-holes, position limit pin 132 is embedded in described the first restraining groove 14, the lock pin 133 of the second bustle pipe 102 is embedded in lock pin qualifying bit groove 16, by joint shell 17, two bustle pipes are flexibly connected thus.
The first bustle pipe 101 end tube chambers are embedded with and in the tube chamber of the first dead bolt 111, the second bustle pipes 102, the second dead bolt 112, the second dead bolt 112 rear ends are set slidably and are provided with a spring 18 and a traction rope 19.
Locking framework of the present utility model comprise along the first bustle pipe 101 length directions and the first bustle pipe 101 slide mutually arrange the first dead bolt 111, be arranged at the second dead bolt 7 on the second bustle pipe 102, be compared with conventional construction difference, lock pin 133 of the present utility model is not fixedly installed on joint shell 17, this lock pin 133 is arranged in the lock pin qualifying bit groove 16 of joint shell 17, and can in locating slot, rotate with the rotation of bustle pipe 102.In addition, the upper end of lock pin qualifying bit groove 16 of the present utility model is also extended with a horizontal expansion groove 161.
This locking framework has locked, in the time that locking framework is positioned at locked position, in the second bustle pipe 102, the second dead bolt 112 is pressed on lock pin 122, in the first bustle pipe 101, the first dead bolt 111 is pressed on the second dead bolt 112, lock pin 133 is fastened in the horizontal expansion groove 161 of upper end of lock pin qualifying bit groove 16, now whole the first bustle pipe 101 and the second bustle pipe 102 and joint shell 17 form an entirety, as Fig. 2, shown in Fig. 5 (1) and Fig. 5 (2).
In the time that this locking framework is positioned at releasing process, user is the reverse pull-out along link position by the second dead bolt 112, as shown in Fig. 3 (1), cause lock pin 133 from horizontal expansion groove 161, to deviate to slip in lock pin qualifying bit groove 16 and down sliding, now the second bustle pipe 102 and the first bustle pipe 101 depart from level connection joint state, the second bustle pipe 102 upwards lifts, and the first dead bolt 111 separates gradually with the second dead bolt 112, as shown in Fig. 3 (2).When the first dead bolt 111 and the second dead bolt 112 are separated to a certain degree; the second dead bolt 112 moves down and reverts to horizontal position; lock pin 133 slips in the horizontal expansion groove 161 in lock pin qualifying bit groove 16; at this moment the first dead bolt 111 is positioned under the second dead bolt 112; as shown in Fig. 3 (3); can make so can not form seaming state between the first bustle pipe 101 and joint shell 17, therefore protect to cover outer field cloth cover and can not be clipped broken.
Fig. 6 has illustrated the revolute joint schematic diagram of release folded state, be specifically basis please continue to refer to Fig. 3 (3), after the first dead bolt 111 upwards rotates, again the second bustle pipe is outwards stretched and causes lock pin 133 from horizontal expansion groove 161, again to slip in lock pin qualifying bit groove 16, restraining groove 132 and lock pin 133 slip in restraining groove 14 and lock pin qualifying bit groove 16 and to restraining groove end respectively like this, two bustle pipes and joint shell 17 are the position of approximately 90 °, as shown in Figure 6.Fig. 8 has provided and has adopted this revolute joint to rotate the signal of the game bed after folding.
Lock pin qualifying bit groove foregoing describes the structure of revolute joint of the present utility model in detail.Lower mask body is introduced release and the process of locking.
Release:
Owing to make traction rope 19 move backward when external force after, the located lateral groove 161 that drives the second dead bolt 112 and depart from lock pin qualifying bit groove 16 upper ends with pendulum lock pin 133, make the second bustle pipe 102 enter into rotary state, because causing the second dead bolt 112 to lose support the first bustle pipe 101, retreating of the first dead bolt 111 entered into rotary state, because joint shell 17 is provided with two restraining grooves 14, 16, therefore the first bustle pipe 101 and the second bustle pipe 102, cause whole revolute joint to turn to the end, two bustle pipes 101, 102 can not form seaming state with joint shell 17, therefore having protected game bed to cover outer field cloth cover can not be clipped broken.
Locking:
Because the first bustle pipe 101 on joint shell 17 and the second bustle pipe 102 can rotate, therefore the process of locking may the first bustle pipe 101 first turn to top, thereby then the second bustle pipe 102 is caught up with the second dead bolt 112 again to be shifted on lock pin qualifying bit groove 16 onto joint by spring 18 locked.Another kind of possibility the second bustle pipe 102 first turn to top, the first bustle pipe 101 is caught up with again, at this moment the tapered end inclined-plane of the first dead bolt 111 promotes slidably the first dead bolt 111 and draws back, thereby be squeezed into the top, locked thereby the first dead bolt 111 comes back in lock pin qualifying bit groove 16 joint under the effect of spring 18.As shown in Figure 4, the game bed that adopts this joint structural representation in this state as shown in Figure 7 for structure after the final release in joint of the present utility model is folding.
The revolute joint of said structure can be realized the convenient folding in joint, and due to unique latch design, two bustle pipes 101,102 and joint shell 17 can not form seaming state, has therefore protected game bed to cover outer field cloth cover and can not have been clipped broken.
As Fig. 6, shown in 7, the utility model also relates to a kind of game bed, comprises upper frame 20 that can be folding, the many vertical rods 21 that upper end portion connects in upper frame 17, the Foldable bottom rack 22 being connected with the underpart of many vertical rods 21.Four cross bars of upper frame 20 have adopted aforesaid revolute joint structure.Design thus, revolute joint structure of the present utility model can also be applied to foldable baby crib, collapsible outdoor desk-chair, children trolley field.
All embodiments are only for illustration of the utility model above, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or variation, therefore all technological schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
