Description
Technical field
This utility model relates to a kind of locking device, especially a kind of rotation lock mechanism.
Background technology
Revolute pair is a kind of common kinematic pair, two components in relative rotation, needs in some work process
To rotate along a direction, the most locked.More existing retaining mechanisms can provide a direction to rotate,
The function that opposite direction is locked.But it is disadvantageous in that mechanism itself can not solve in motor process voluntarily
Lock.
Utility model content
This utility model purpose is to provide a kind of rotation lock mechanism, it is possible to realize the reverse lock in rotation process
Extremely, and can unlock voluntarily.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of rotation lock mechanism, including moving block one, poke rod, connecting rod one, latch segment, moving block
Two, ratchet, connecting rod two, spring, ratchet, bearing pin and shifting chute, described moving block one and ratchet are fixing even
Connecing, moving block one and ratchet are flexibly connected with moving block two by bearing pin, and described moving block one is provided with shifting
Dynamic groove, shifting chute is flexibly connected with one end of poke rod by pin, the other end of described poke rod and connecting rod
One is flexibly connected, and one end of described connecting rod one is connected on moving block two by pin, the other end and connecting rod two
One end be flexibly connected, the other end of described connecting rod two is movably connected on ratchet, and described ratchet one end is passed through
Pin is connected to moving block two, and the other end coordinates with ratchet, and the side of described ratchet is fixed with spring, described
The other end of spring is fixed on moving block two, and latch segment is fixed on moving block two.
Preferably, when the position of connecting rod one and connecting rod two is in straight line, latch segment is fitted with connecting rod two.
The beneficial effects of the utility model are:
This utility model promotes poke rod to move by moving block one, and poke rod promotes connecting rod one to move, connecting rod
One promotes connecting rod two to move.Connecting rod two promotes ratchet compression spring to move, when connecting rod one and connecting rod two conllinear,
Ratchet is then fixed on a certain position.And now ratchet cannot coordinate with ratchet, then moving block one and rotation
Block two can opposing move, and is returned to initial position.Complete the unlocking function after locking.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model released state structural representation.
1, moving block one, 2, poke rod, 3, connecting rod one, 4, latch segment, 5, moving block two, 6, spine
Pawl, 7, connecting rod three, 8, spring, 9, ratchet, 10, bearing pin, 11, shifting chute.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model is permissible
The multitude of different ways being defined by the claims and covering is implemented.
As it is shown in figure 1, a kind of rotation lock mechanism include moving block 1, poke rod 2, connecting rod 1,
Latch segment 4, moving block 25, ratchet 6, connecting rod 27, spring 8, ratchet 9, bearing pin 10, shifting chute
11.Moving block 1 and the fixing connection of ratchet 9, moving block 1 and ratchet 9 are by bearing pin and moving block two
5 are flexibly connected.Being provided with shifting chute 11 on moving block 1, shifting chute 11 is by pin and poke rod 2
One end be flexibly connected, the other end of poke rod 2 is flexibly connected with connecting rod 1.One end of connecting rod 1 leads to
Crossing pin to be connected on moving block 25, the other end is flexibly connected with one end of connecting rod 27, connecting rod 27
The other end be movably connected on ratchet 6, ratchet 6 one end is connected to moving block 25 by pin, another
End coordinates with ratchet 9, and the side of ratchet 6 is fixed with spring 8, and the other end of spring 8 is fixed on moving block
On 25.Latch segment 4 is fixed on moving block 25, when the position of connecting rod 1 and connecting rod 27 is in one
During bar straight line, latch segment 4 is fitted with connecting rod 27.
When moving block 1 and ratchet 9 relatively rotate with moving block 25, ratchet 9 and ratchet 6 coordinate,
Ensure moving block, 1 and moving block 25 only along direction relative motion in opposite directions, the opposing direction of motion can not
Rotate, so since, when moving block 1 and moving block 25 opposing direction of motion stress, then can be fixed on
A certain position, mechanism is in locking state.
When move toward one another to the position shown in Fig. 2, moving block 1 promotes poke rod 2 to move, poke rod 2
Promoting connecting rod 1 motion, connecting rod 1 promotes connecting rod 27 motion.Connecting rod 27 promotes ratchet 6 to compress bullet
Spring 8 moves, and when connecting rod 1 and connecting rod 25 conllinear, ratchet 6 is then fixed on a certain position.And
Now ratchet 6 cannot coordinate with ratchet 9, then moving block 1 and moving block 25 can opposing move, and returns
Arrive initial position again.Complete the unlocking function after locking.
When move toward one another to a certain position, moving block 1 drivening rod 1 moves, and connecting rod 1 drives
Connecting rod 27 moves, then connecting rod 1 and connecting rod 27 be not at collinear position.Rely on connecting rod 27 pull and
The restoring force of spring 8, forces ratchet 6 again to coordinate with ratchet 9, completes a locking and release period.
Above-described this utility model embodiment, is not intended that the limit to this utility model protection domain
Fixed, any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all
Within claims of the present utility model should be included in.
