The elastic moving part 3 penetrates through the fixed part 2 and can move telescopically relative to the fixed part 2, and when the elastic moving part extends out, the elastic moving part can be in contact with the rotating part 1 and can lock the rotating part 1. Under the action of external force, the rotating part 1 relatively deflects by a certain angle, and the elastic moving part 3 retracts under the extrusion of the elastic moving part because the contact surface is of a curved surface structure, so that the rotating part 1 is released.

In order to lock the rotating member 1 and the fixing member 2 conveniently, the fixing member 2 may be directly fixed to a side wall of the rotating member 1. When the assembly that needs to drive rotation is great, for example when the rotatory bucket ladle 12 of needs drive rotates, can set up lug 11 and ladle 12 fixed connection: when the central axis of the projection 11 coincides with the axis of the rotating shaft of the barrel 12, the projection 11 can drive the barrel 12 to rotate synchronously.

Specifically, a protruding block 11 is disposed at an end of the rotary barrel body 12, and the fixing member 2 is structurally and fixedly connected with the protruding block 11. The protruding block 11 is a rectangular structure, a locking concave point 111 is arranged on the side wall of the protruding block 11, and the elastic moving part 3 is connected with the rotating part 1 through the locking concave point 111.

It should be noted that the volume of the projection 11 is not too large, which would affect the volume of the related equipment and also the disassembly of the rotating member 1.

In addition, a locking concave point 111 is arranged on the side wall of the convex block 11, the locking concave point 111 is a concave curved surface structure, and the elastic moving part 3 can be attached to and connected with the rotating part 1 through the locking concave point 111: the end of the elastic movable member 3 is inserted into the protrusion 11, and when the rotating member 1 is applied with an external force and presses the elastic locking member 31, the elastic locking member 31 can be disengaged from the locking recess 111.

As an alternative embodiment, the fixing member 2 is a snap gear. The meshing gear can rotate under the drive of the driving device and drives the rotating piece 1 to rotate. The driving device is a motor with a gear or rack structure matched with the fixing part 2, and the like.

The engagement gear extends outwards towards one side of the projection 11 to form two oppositely arranged baffles 21, and a groove 22 for accommodating the projection 11 is arranged between the two baffles 21, as shown in fig. 6. At least one baffle plate 21 is provided with an elastic moving member 3, that is, the elastic moving member 3 is located on the baffle plate 21 and can move telescopically relative to the baffle plate 21.

The elastic movable member 3 on the blocking plate 21 can lock and release the rotating member 1, and a blind hole or the like is formed at a corresponding position of the blocking plate 21 to accommodate the elastic movable member 3. It should be noted that the length of the elastic element 32 in the resting state is not less than the length of the second through pillar 313, so as to ensure that the elastic element 32 can be deformed by being compressed by an external force.

In addition, in order to improve the reliability of the device, two baffles 21 arranged oppositely can be fixedly connected, as shown in fig. 6-7, and the groove 22 and the baffles 21 form a structure similar to a Chinese character 'ao'.

In order to ensure the normal use of the elastic movable member 3, specifically, a cavity is present in the baffle plate 21, which can accommodate the elastic member 32 and the locking member 31, wherein the fixing plate 311 and the second through pillar 313 of the locking member 31 and the elastic member 32 are located in the cavity, and the first through pillar 312 protrudes through the baffle plate 21. The chamber may be provided with a snap-fit cover which is connected to the flap 21 by means of snap-fit means, the presence of which also facilitates the mounting of the flexible mobile element 3.

In addition, as an alternative embodiment, a counter bore 211 may be provided on the baffle plate 21, a locking cover 4 is fixedly provided outside the counter bore 211, one end of the elastic moving member 3 is connected to the protrusion 11 through the counter bore 211, and the other end is connected to the locking cover 4, as shown in fig. 7, at this time, the locking cover 4 is fixedly connected to the baffle plate 21 through a bolt.

The locking cover 4 can help limit the elastic movable member 3 and prevent the elastic movable member 3 from falling off the baffle 21.

In addition, when a large gap exists between the rotating member 1 and the pet litter box casing for the movement of the rotating member 1, the movement of the rotating member 1 is not limited by the opening position.

When in use, the rotating member 1 is inserted into the fixed member 2 through the groove 22 according to a certain angle, the first penetrating column 312 in the elastic movable member 3 can be just inserted into the locking concave point 111, at this time, both sides of the protruding block 11 are connected with the elastic movable member 3, and the rotating member 1 is fixedly connected with the fixed member 2. When the fixed member 2 is driven to rotate by the driving means, the rotating member 1 can be rotated in synchronization therewith. When the rotating member 1 needs to be removed, a force moving towards the side direction is applied to the rotating member 1, at this time, the elastic moving member 3 is compressed by the locking concave point 111 to retract into the fixed member 2, and the rotating member 1 is released. Through the structure, the manual disassembly and assembly of the rotating part 1 can be conveniently realized.
