Shell 150 includes the first shell 161 and second housing 163, and the first shell 161 and second housing 163 are removably
Connection, and be arranged along the axisymmetrical of shaft 110.By the way that shell 150 is divided into two, it is easily installed and dismantles.First shell
161 and second housing 163 lid close formed accommodating cavity, be located at except the second segmentation 113 and sliding block 130.
Preferably, fluted 151 are all provided on the first shell 161 and second housing 163.Boss there are two being set on sliding block 130
131, two boss 131 are also distributed along the axisymmetrical of shaft 110, on the position of one of boss 131 and the first shell 161
Groove 151 position it is corresponding, the position of another boss 131 is opposite with the position of groove 151 on second housing 163
It answers.
Optionally, the first shell 161 and second housing 163 can be fastenedly connected by screw, can also be connected by bolt
Connect, alternatively, using be bonded, weld, snapping connection, hingedly, magnetic attracting connect etc. modes, be not especially limited here.
A kind of tipping arrangement provided in this embodiment, including flip piece and above-mentioned rotation limiting structure 100, flip piece with
Shaft 110 is fixedly connected, and flip piece is able to achieve multipurpose rotary limit.Specifically, it is fixedly connected due to flip piece with shaft 110,
In flip piece rotation process, shaft 110 rotates, and band movable slider 130 is moved along shaft 110, meanwhile, the boss on sliding block 130
131 groove 151 in shell 150 moves.When boss 131 is moved to the end of groove 151, sliding block 130 stops movement, this
When, flip piece can only be rotated backward, shaft 110 is reversely rotated.
Rotation limiting structure 100 and tipping arrangement provided by the utility model, installation process and working principle are as follows:
First sliding block 130 is installed in the second segmentation 113 of shaft 110, sliding block 130 is set in by mounting hole 135 to be turned
On axis 110, it is threadedly engaged the first screw thread and second.The first shell 161 and the lid of second housing 163 are closed again, cover at sliding block
130 and shaft 110 periphery, protrude into the boss 131 on sliding block 130 in the groove 151 of shell 150.Also, shell 150
One end is mounted at positioning step 117, and the other end of shell 150 is mounted in third segmentation 115.Preferably, boss 131 and cunning
Block 130 is integrally formed, and the first shell 161 and second housing 163 are fastenedly connected by screw.
Shaft 110 is rotated clockwise, sliding block 130 moves right along shaft 110, meanwhile, 131 edge of boss on sliding block 130
Groove 151 in shell 150 moves right.When boss 131 is moved to the right end end of groove 151, sliding block 130 stops moving
It is dynamic.At this point, shaft 110 can only be rotated backward, it is rotated in the counterclockwise direction shaft 110, sliding block 130 is along shaft 110 to moving to left
It is dynamic, meanwhile, groove 151 of the boss 131 in shell 150 on sliding block 130 is moved to the left, until boss 131 is moved to groove
When 151 left end end, sliding block 130 stops movement.The moving distance of sliding block 130 is limited by the way that the length of groove 151 is arranged,
Limit the rotation angle of shaft 110.In this manner it is achieved that shaft 110 rotation turn around and one circle more than.
Flip piece is fixedly connected in shaft 110 by tipping arrangement provided in this embodiment, rotates flip piece, i.e. energy band
Movable slider 130 is moved along shaft 110, and the moving distance of sliding block 130 is limited using 151 length of groove being arranged on shell 150,
The rotational angle of shaft 110 is controlled, so as to realize that flip piece carries out multipurpose rotary limit.
In conclusion rotation limiting structure 100 provided by the utility model and tipping arrangement have the following aspects
The utility model has the advantages that
Rotation limiting structure 100 provided by the utility model, including shaft 110, sliding block 130 and shell 150.Sliding block 130
