It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The embodiment of the utility model provides a damping rotating-structure 100, wherein, this damping rotating-structure 100 can be used in any structure that needs rotate to connect, in this embodiment, it mainly is applied to the cloud platform, from shooting auxiliary device 1000 such as rapping bar.

As shown in fig. 1 and fig. 2, the damping rotation structure 100 includes a first connecting member 1, a second connecting member 2, a damping kit 3 and a rotation shaft assembly 4, wherein the first connecting member 1 and the second connecting member 2 are connected in a relative rotation manner, and both the first connecting member 1 and the second connecting member 2 are connecting members capable of playing a connecting role, which can be telescopic rods with adjustable length, and also can be connecting rods 1, connecting seats 11, connecting sheets and the like with fixed length, and which connecting members are specifically adopted can be determined according to actual conditions.

In the embodiment, the connection end of the first connecting member 1 is rotatably connected to the second connecting member 2 by using the connection seat 11. In order to realize the rotational connection between the first connecting member 1 and the second connecting member 2, as shown in fig. 1 to 3, a connecting end (specifically, a connecting seat 11) of the first connecting member 1 is provided with a mounting groove 12, and a connecting end of the second connecting member 2 is inserted into the mounting groove 12. In order to facilitate the installation of the damping sleeve 3 and the rotating shaft assembly 4, as shown in fig. 2, the connecting end of the second connecting member 2 is provided with a transverse (specifically, axial) mounting hole 21. As shown in fig. 2 to 6, the damping sleeve 3 is installed in the installation hole 21 in the depth direction of the installation hole 21, and a damping insertion hole 32 (see fig. 4) is formed, and it can be understood that the damping sleeve 3 has a hollow cylindrical structure.

In order to ensure that the first connecting piece 1 and the second connecting piece 2 can rotate only by overcoming the damping force when rotating relatively, the middle part of the rotating shaft component 4 is inserted into the damping jack 32 in an interference manner, and two ends of the rotating shaft component 4 are fixedly connected to the connecting ends of the first connecting piece 1 at two sides of the mounting groove 12 respectively.

As shown in fig. 2 to 4 and 6, in order to realize the interference fit between the rotating shaft assembly 4 and the damping insertion hole 32, at least one flange 311 is convexly provided on the inner circumferential wall of the damping sleeve 3 in the damping insertion hole 32. That is, the flange 311 is protruded from the inner peripheral wall of the damper kit 3 toward the inner diameter direction of the mounting hole 21 (i.e., the direction toward the rotary shaft assembly 4). It is understood that the flange 311 is a circumferential flange 311, and is closely attached to the outer circumferential wall of the rotary shaft assembly 4.

Thus, when the first link 1 and the second link 2 relatively rotate, the first link 1 and the second link 2 can realize the damped rotation by the pressing of the outer peripheral wall of the rotary shaft assembly 4 and the flange 311. Specifically, in this embodiment, the rotating shaft assembly 4 and the first connecting member 1 are fixed, and the peripheral wall of the damping sleeve 3 is fixedly disposed in the mounting hole 21, so as to ensure that the damping sleeve 3 and the second connecting member 2 are fixedly connected, so that when the second connecting member 2 rotates relative to the first connecting member 1, the damping sleeve 3 and the second connecting member 2 can rotate together, but because the flange 311 of the damping sleeve 3 is in interference fit with the peripheral wall of the rotating shaft assembly 4, when the second connecting member 2 drives the damping sleeve 3 to rotate around the rotating shaft assembly 4, the friction force generated by the extrusion between the flange 311 of the damping sleeve 3 and the peripheral wall of the rotating shaft assembly 4 must be overcome. That is, the damping force of the first link 1 and the second link 2 in the rotation damping structure 100 in relative rotation damping can be achieved by the friction between the flange 311 of the damping sleeve 3 and the outer peripheral wall of the rotating shaft assembly 4.

In summary, compared with the prior art, the damping rotating structure 100 has at least the following beneficial effects: the damping rotation structure 100 is provided with a transverse mounting hole 21 at a connecting end of a second connecting piece 2, a mounting hole 12 is provided at a connecting end of a first connecting piece 1, a damping jack 32 is formed on a damping sleeve 3, and at least one flange 311 is convexly provided on an inner peripheral wall of the damping sleeve 3, so that the damping sleeve 3 is fixedly mounted in the mounting hole 21 along a depth direction of the mounting hole 21, the connecting end of the second connecting piece 2 with the damping sleeve 3 built therein is inserted into the mounting hole 12 of the first connecting piece 1, and a rotating shaft component 4 is inserted into the damping sleeve hole, so that a middle part of the rotating shaft component 4 is in interference fit with the flange 311 of the damping sleeve 3, and two ends of the rotating shaft component are fixedly connected to the connecting end of the first connecting piece 1 at two sides of the mounting hole 12 respectively, thereby generating a friction force by extrusion between the flange 311 of the damping sleeve 3 and the outer peripheral wall of the rotating shaft component 4, a relative damped rotation with a suitable damping force between the first connecting part 1 and the second connecting part 2 is achieved.

Generally, the damping force of the damping rotating structure 100 does not need to be continuously adjusted, and once the damping force is assembled, a more appropriate damping force can be obtained, so that the assembly process is simple and convenient, and the assembly efficiency is high.

In order to make the technical solution of the present invention better understood, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to fig. 1 to 9.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2 and 4, a boss 421 is protruded from the outer peripheral wall of the rotating shaft assembly 4, and the boss 421 extends in the depth direction of the mounting hole 21 (i.e., the axial direction of the rotating shaft assembly 4). In the present embodiment, at least two flanges 311 are provided, wherein all the flanges 311 are arranged with a gap along the depth direction of the mounting hole 21 (i.e. the length direction of the damping sleeve 3), and the bosses 421 are tightly fitted with the flanges 311.

It can be understood that, due to the tight fit between at least two flanges 311 of the damping sleeve 3 and the boss 421 of the rotating shaft assembly 4, during the relative rotation, the damping rotation with proper damping force between the first connecting member 1 and the second connecting member 2 can be realized by the friction force generated by the pressing between the boss 421 and each flange 311. And because the flange 311 on the inside of damping external member 3 sets up along the length direction clearance of damping external member 3, like this, at the rotation in-process, the boss 421 of pivot subassembly 4 can extrude a plurality of flanges 311 to form a plurality of stress points, do benefit to and improve first connecting piece 1 and the relative damping pivoted reliability and stability of second connecting piece 2.

It should be noted that, in this embodiment, the bosses 421 may be convex strips, wherein one boss 421 corresponds to all the flanges 311 disposed in the gap. Of course, at least two bosses 421 may be provided, and each boss 421 is provided along the axial gap of the rotating shaft assembly 4, and the bosses 421 correspond to the flanges 311 one by one. In addition, when there are at least two bosses 421, they may be arranged in a row, or may be arranged in a staggered manner, and the arrangement may be determined according to the arrangement of the flanges 311. Specifically, in the present embodiment, the number of the bosses 421 is one, and the bosses are convex strips. Correspondingly, the number of the flanges 311 is at least two, and each flange 311 is an annular flange 311.

It should also be noted that the number of the flanges 311 may be one, for example, an annular flange 311 is matched with a strip-shaped boss 421.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, fig. 4 and fig. 7, since the friction between the rotating shaft assembly 4 and the damping sleeve 3 is frequent, in order to reduce the wear between the rotating shaft assembly 4 and the damping sleeve 3, the top surface of the boss 421 is a plane or an arc surface, and the flange 311 is an arc flange 311.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2 to 5 and 7, because the manufacturing process requirement and the manufacturing cost of the rotating shaft are high, and the utilization rate of the rotating shaft in the rotating structure is high, for reducing the manufacturing cost and the use cost, the rotating shaft assembly 4 includes a shaft 41 and a sleeve 42, wherein two ends of the shaft 41 are respectively fixedly connected to the connecting ends of the first connecting member 1 at two sides of the mounting groove 12. The middle portion of the shaft 41 is a sleeve portion 411, the sleeve 42 is fixedly sleeved on the sleeve portion 411 of the shaft 41, and as shown in fig. 8, a boss 421 is convexly arranged on the outer peripheral wall of the sleeve 42.

It is understood that the interference fit of the rotating shaft assembly 4 and the damping sleeve 3 is mainly realized by the fit of the sleeve 42 and the damping sleeve 3, and specifically, by the friction force generated by the pressing between the boss 421 of the sleeve 42 and the flange 311 of the damping sleeve 3.

Specifically, in the present embodiment, as shown in fig. 1 to 3, the first connecting member 1 adopts the connecting seat 11 as the connecting end, wherein the middle portion of the connecting seat 11 is provided with an installation groove 12 having an avoiding opening (not shown) along the axial direction thereof, and the connecting seat 11 is provided with a first connecting hole 111 and a second connecting hole 112 communicating with the installation groove 12 at two sides of the installation groove 12. The first connection hole 111 and the second connection hole 112 are detachably covered with a decoration sheet 113.

In addition, as shown in fig. 9, the two ends of the shaft 41 are respectively a head part 412 and a connecting part 413, wherein one end of the socket part 411 of the shaft 41 is connected to the head part 412, and the other end is connected to the connecting part 413. As shown in fig. 2, 3 and 5, the rotating shaft assembly 4 further includes a nut 43, wherein the nut 43 is sleeved on the connecting portion 413 and inserted into the second connecting hole 112. Correspondingly, the head 412 of the shaft 41 is inserted into the first connection hole 111, so as to connect the two ends of the rotating shaft assembly 4 to the connection ends of the first connecting member 1.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2 to fig. 5, fig. 7 and fig. 9, in order to realize the fixed sleeve connection between the shaft 41 and the sleeve 42, the sleeve 42 is prevented from rotating relative to the shaft 41, the sleeve connection portion 411 of the shaft 41 is a special-shaped shaft, wherein the outer peripheral wall surface of the special-shaped shaft 411 includes a first limiting surface 4111, the first limiting surface 4111 extends along the axial direction of the special-shaped shaft 411, and correspondingly, the sleeve 42 is provided with a through hole 422 adapted to the special-shaped shaft 411 along the axial direction thereof. It is understood that the hole shape of the through hole 422 is the same as the shape of the cross section of the profiled shaft element 411.

Specifically, in the present embodiment, the first limiting surface 4111 is a plane, and correspondingly, as shown in fig. 8, a second limiting surface 4221 corresponding to the first limiting surface 4111 is formed on the hole wall of the through hole 422, and when the shaft member 41 and the sleeve 42 are sleeved, the first limiting surface 4111 and the second limiting surface 4221 are disposed opposite to each other, so as to limit the relative rotation between the sleeve 42 and the shaft member 41.

Note that, the shaft member 411 having a different cross-sectional shape is referred to as the shaft member 41 having a different cross-sectional shape, and actually, the shaft member 411 may have a trapezoidal, triangular, or key-shaped cross-sectional shape.

Preferably, the sleeve 42 may be made of a hardware material, and correspondingly, the damping sleeve 3 may also be made of a hardware material. Thus, the friction between the two hardware pieces is beneficial to increasing the damping force of the damping rotating structure 100 and reducing the abrasion, thereby improving the reliability and the stability of the damping rotation and prolonging the service life of the whole product.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 7, the damping sleeve 3 has a gap 33 in its circumferential direction. To ensure that the boss 421 on the rotating assembly can be separated from the flange 311 on the damping sleeve 3 during rotation, rather than maintaining an interference fit at all times, the size of the gap 33 is larger than the size of the boss 421. Specifically, in the present embodiment, when the second connecting member 2 rotates relative to the first connecting member 1 to be parallel to the first connecting member 1 (i.e. when the second connecting member 2 rotates and folds to one side of the first connecting member 1, as shown in fig. 1), as shown in fig. 4 and 7, the notches 33 of the damping sleeve member 3 can be distributed at positions corresponding to the bosses 421 along with the rotation of the damping sleeve member 3.

It can understand, because of the size of breach 33 is greater than the size of boss 421, when breach 33 distributes on the position that boss 421 corresponds, boss 421 can't contact with the flange 311 of breach 33 both sides promptly, thereby can not extrude flange 311, in order to ensure no longer to have damping force between first connecting piece 1 and the second connecting piece 2, or there is minimum damping force, therefore, can hug closely in one side of first connecting piece 1 naturally through the action of gravity of second connecting piece 2 self, do benefit to the one side of folding first connecting piece 1 with second connecting piece 2.

In the present embodiment, two damping fins 31 are disposed on two sides of the positioning table 211. In order to avoid the interference between the positioning table 211 and the boss 421 when the positioning table 211 rotates to the position where the notch 33 is opposite to the boss 421, the positioning table 211 is spaced from the boss 421.
