The state of the turntable 3 can be controlled by sliding the first flap 24 and the second flap 25 in the sliding direction as described above.

Specifically, the first movable plate 24 and the second movable plate 25 are each provided with a first guide groove 242 and a second guide groove 243 extending in the sliding direction, and the first guide groove 242 on one movable plate corresponds to the second guide groove 243 on the other movable plate in the up-down direction, the guide 26 is connected to the fixed plate so that the guide 26 is fixed to the position of the fixed plate, the guide 26 passes through the first guide groove 242 and the second guide groove 243 which are opposite to each other, and then the reset member 27 is provided in the first guide groove 242, the reset member 27 may be an elastic member having a deformation capability and capable of applying a force to the outside, such as an elastic sheet or a spring, and the like, one end of the reset member 27 abuts against the guide 26 and the other end abuts against the first guide groove 242, the reset member 27 is telescopically deformed, and the reset member 27 continuously applies a first pushing force (a reset acting force) to the movable plates, the direction of which is the same as the direction from the second position to the first position, so as to push the movable plates to the first position so that the locking member 21 can be engaged with the groove 31 and prevent the locking member 21 from being moved to the first position in the first position artificially.

Referring to fig. 7, taking the reset element 27 as an example of a spring, the first guide slot 242 has a first end 2421 and a second end 2422 opposite to each other, a direction from the first end 2421 to the second end 2422 is consistent with a direction from the first position to the second position, the guide element 26 extends into the first guide slot 242 with a space left therebetween, preferably, the guide element 26 extends into the second end 2422, the spring is disposed in the first guide slot 242, one end of the spring abuts against the first end 2421, and the other end of the spring abuts against the guide element 26, so that the spring can apply a first pushing force directed from the second end 2422 to the first end 2421 through the guide element 26, thereby enabling the movable plate to be in the first position.

The first guide grooves 242 are formed in the first movable plate 24 and the second movable plate 25, and the restoring member 27 is disposed in each of the first guide grooves 242, that is, both the first movable plate and the second movable plate are pushed by the first pushing force, so that the first locking member 211 and the second locking member 212 can be pressed toward the rotary plate 3 to lock the rotary plate 3.

The second guide groove 243 is provided to facilitate the passage of the guide 26 so that the guide 26 can reach the first guide groove 242; in addition, the second guide groove 243 also has a certain length in the sliding direction to satisfy the sliding of the corresponding sliding plate in the sliding direction.

The first locking member 211 and the second locking member 212 are both attached to the same side of the sliding direction of the corresponding movable plate (rotary plate 3); the driving assembly 6 is disposed at the other side of the sliding direction of the turntable 3, and the driving assembly 6 and the locking member 21 are disposed at two sides of the movable plate in the sliding direction, that is, the direction from the driving assembly 6 to the movable plate is the direction from the first position to the second position, so that the driving assembly 6 can apply a second thrust (opposite to the direction of the first thrust) to the movable plate, so that the movable plate moves to the second position to unlock the turntable 3.

Therefore, when the suspension member needs to be rotated, the first movable plate 24 and the second movable plate 25 can be pushed to the second position by the driving assembly 6, so that the rotary plate 3 is in the unlocking state, at this time, the rotary plate 3 can be rotated according to the required rotation angle, so that the suspension member rotates by the required angle, then the driving assembly 6 is withdrawn, the first movable plate 24 and the second movable plate 25 slide to the first position under the action of the first pushing force of the resetting member 27, so that the rotary plate 3 is in the locking state again, and the suspension member is in the rotated angle unchanged.

In one embodiment, the turntable 3 is rotatably connected to the mounting base 1 via a rotating shaft 4, and the turntable 3 is connected to the rotating shaft 4 (e.g., welded or keyed) so that the rotating shaft 4 and the turntable 3 can rotate synchronously. The upper part of the rotating shaft 4 is rotatably connected with the mounting seat 1, the lower part of the rotating shaft 4 can be connected with a hanging piece, and the rotating disc 3 is positioned in the middle area of the rotating shaft 4.

The first fixing plate 22 and the second fixing plate 23 are provided with first through holes 221, the first through holes 221 are circular holes for the rotation shaft 4 to pass through, the first movable plate 24 and the second movable plate 25 are provided with second through holes 241, the second through holes 241 (kidney-shaped holes) extend in the sliding direction and are larger than the sliding stroke of the two movable plates, the second through holes 241 also allow the rotation shaft 4 to pass through, and the two movable plates are prevented from interfering with the rotation shaft 4 when sliding.

First retaining member 211 and second retaining member 212 are the cylinder structure, and the gullet of spacing recess 31 is the arc wall, the radius of arc wall and retaining member 21's radius phase-match, or, the radius of arc wall slightly is greater than the radius of retaining member 21 for under the primary importance, the cylinder of retaining member 21 can laminate with the arc wall, makes retaining member 21 can oppress spacing recess 31, promotes retaining member 21 to the spacing effect of antiport 3.

Spacing recess 31 still includes two spigot surfaces of being connected with the arc wall, and in the week of carousel 3, two spigot surfaces set up relatively, and in the footpath of carousel 3, from the extroversion, the distance between two spigot surfaces diminishes gradually to make spacing recess 31 (from the extroversion in) uncovered diminishing gradually, make things convenient for retaining member 21 to cooperate through spacing recess 31's uncovered and spacing recess 31.

Of course, the guide surface is preferably a curved surface, but may also be a flat surface.

Since the first movable plate 24 and the second movable plate 25 can independently slide relative to the fixed plate, so that the first locking member 211 and the second locking member 212 can also independently slide relative to the fixed plate, a protrusion is formed between adjacent limiting grooves 31 of the rotary table 3, while the angle of the rotary table 3 during rotation is uncertain, in some cases, when the first locking member 211 and the second locking member 212 move towards the first position, the locking member 21 may just abut against the protrusion, so that the locking member 21 cannot be matched with the limiting grooves 31, thereby affecting the locking of the rotary table 3.

In this application, first retaining member 211 misplaces with second retaining member 212 in carousel 3's circumference, and circular angle between the axle center of relative carousel 3 is the integral multiple of non-tooth pitch angle, this just makes if first retaining member 211 just in time offsets with the arch of carousel 3, second retaining member 212 then can not offset with the arch, and can cooperate with spacing recess 31 smoothly, thereby make anyhow, can make at least one spacing post can with spacing recess 31 spacing cooperation, so that carousel 3 is in locking condition.

In the locking state, the locking member 21 of one of the two movable plates is in limit fit with the limit groove 31, and the locking member 21 of the other movable plate abuts against the protrusion formed by the two adjacent limit grooves 31.

The central angle between the second locking member 212 and the first locking member 211 is N +0.5 times (e.g. 1.5 times as shown in fig. 9) the pitch angle, where N is a natural number, so that when the two movable plates move from the second position to the first position, even if some of the locking members 21 are just against the protrusions of the rotary plate 3, another part of the locking members 21 can just correspond to the limiting recesses 31, thereby ensuring that at least one of the locking members 21 can be inserted into the limiting recesses 31 in any case in the first position.

With such an arrangement, only one locking member 21 between the first locking member 211 and the second locking member 212 can be engaged with the retaining groove 31, and the other locking member 21 can only abut against the protrusion.

Of course, the central angle between first locking member 211 and second locking member 212 may be an integer multiple of the pitch angle such that, in the first position, first locking member 211 and second locking member 212 will simultaneously mate with their respective mating recesses.

The first locking member 211 is provided in two; the second locker 212 is provided with one, and two first lockers 211 are respectively positioned at both sides of the second locker 212 along the circumference of the turntable 3.

In the first position, the direction between the second locking member 212 and the center of the rotary table 3 is the same as the sliding direction. That is to say, when the second locking member 212 is used to lock the turntable 3, the second locking member 212 is engaged with the limiting groove 31 and presses the turntable 3 towards the center of the turntable 3, so that the first pushing force of the second locking member 212 does not drive the turntable 3 to rotate and the purpose of locking the turntable 3 is achieved, and when the two first locking members 211 are respectively engaged with the limiting groove 31, the two first locking members 211 are respectively located at two sides of the sliding direction passing through the center of the turntable 3, and the resultant force formed by the first pushing force of the first locking members 211 also points to the center of the turntable 3, so that the turntable 3 is not driven to rotate, thereby ensuring that the turntable 3 cannot rotate in the first position.

Specifically, the central angle of the two first locking members 211 is an integral multiple of the pitch angle (e.g., 3 times as shown in fig. 9), so that the two second locking members 212 on the first movable plate 24 can be inserted into the corresponding limiting recesses 31 at the same time, and the central angle between the second locking member 212 and any one of the first locking members 211 is N +0.5 times (e.g., 1.5 times as shown in fig. 10), where N is a natural number, so that when the two movable plates move from the second position to the first position, even if some of the locking members 21 are just against the protrusions of the turntable 3, another part of the locking members 21 can be smoothly inserted into the limiting recesses 31, thereby ensuring that at least one of the locking members 21 can be inserted into the limiting recesses 31 in any first position.

In the embodiment shown in fig. 9, two first locking members 211 are inserted into the engagement grooves, and the second locking members 212 are abutted against the protrusions of the turntable 331; in the embodiment shown in fig. 10, the second locking member 212 is inserted into the engagement recess, and the two first locking members 211 abut against the protrusions of the turntable 3.

Of course, in another embodiment, the number of the first locking members 211 may be one, and the number of the second locking members 212 may be two.

The first locking member 211 and the second locking member 212 are located on the same side of the two movable plates along the extending direction (sliding direction) of the first guide groove 242, and the sides of the two movable plates away from the first locking member 211 are arranged to abut against a pushing plane; the driving assembly 6 includes a push plate 61, the push plate 61 is disposed in a sliding manner along the extending direction (sliding direction) relative to the two fixing plates, and the plate surface of the push plate can be abutted to the two abutting planes.

The movable plate protrudes from the fixed plate at an end facing the driving assembly 6 such that the push plate 61 abuts the protruding end of the movable plate and pushes the protruding end to slide into overlapping with the fixed plate until the push plate 61 abuts the fixed plate, at which time the locking member 21 reaches the second position. The push plate 61 can only move to a position abutting against the fixed plate at most, so that the moving stroke of the push plate 61 is limited, the overlarge stroke between the first position and the second position is avoided, and the movable plate is also prevented from being subjected to overlarge second thrust.

As for the driving assembly 6, the driving assembly 6 comprises a pushing member comprising a pushing plate 61 and a connecting plate 62 connected with each other, the connecting plate 62 is slidably connected in a preset position along a sliding direction, and the pushing plate 61 is opposite to the two movable plates.

The connecting plate 62 is horizontally disposed, the push plate 61 is connected to one end of the connecting plate 62, and when the mounting base 1 moves to the preset position, the push plate 61 faces the movable plates, so that when the connecting plate 62 moves towards the movable plates in the sliding direction, the push plate 61 moves towards the movable plates and pushes the two movable plates to slide to the second position to unlock the turntable 3.

Referring to fig. 1, the power device of the connecting plate 62 may be an air cylinder 63, and the air cylinder 63 pushes the connecting plate 62 to slide in the sliding direction, but of course, the power device of the connecting plate 62 may also be a linear motor or the like.

Referring to fig. 6, 7 and 11, the guide member 26 includes a guide portion 261 and a stopper portion 262, both of which are bar-shaped, the guide portion 261 extends in the thickness direction of the first fixing plate 22 and is slidably inserted into the corresponding first guide groove 242 and second guide groove 243; one end of the limiting portion 262 is connected to the guiding portion 261, and the other end extends in a direction away from the guiding portion 261, and the limiting portion 262 is located in the first guiding groove 242, and the length thereof is smaller than that of the first guiding groove 242.
