As shown in fig. 1 and 2, a rotation connection structure according to an embodiment includes a main body 100, a rotating body 200, and a rotating shaft 300, wherein the rotating body 200 is rotatably connected to the main body 100 via the rotating shaft 300.

Referring to fig. 2, 4 and 6, specifically, the rotating shaft 300 is rotatably disposed on the main body 100, and the rotating shaft 300 is inserted into the rotating body 200, so that when the rotating body 200 is rotated, the rotating body 200 can rotate around the axis of the rotating shaft 300 relative to the main body 100.

More specifically, the main body 100 is provided with a mounting groove 104, and the rotating shaft 300 is rotatably inserted into the mounting groove 104.

As shown in fig. 2 and 3, the main body 100 is provided with a plurality of positioning grooves 101, and the plurality of positioning grooves 101 are sequentially arranged around the axis of the rotating shaft 300, that is, the plurality of positioning grooves 101 are arranged along the circumferential direction of the rotating shaft 300.

In the above-mentioned rotation connection structure, the rotation body 200 can rotate around the axis of the rotation shaft 300 relative to the main body 100, and when the rotation action of the rotation body 200 is performed, the rotation body 200 can drive the elastic member 400 to rotate around the axis of the rotation shaft 300, so that the positioning portions 410 of the elastic member 400 penetrate into different positioning grooves 101. Wherein, because the elastic member 400 itself has a certain elasticity, when the rotator 200 rotates, and the positioning portion 410 is switched to enter different positioning grooves 101, the positioning portion 410 can be deformed by the extrusion of the groove wall of the positioning groove 101, so that the elastic potential energy of the elastic member 400 is changed, and the operator can feel the damping effect. In the above-mentioned rotary connection structure, the elastic member 400 is used to cooperate with the positioning groove 101 to generate a damping effect, and the rotary connection structure has a simple structure, a low cost, an easy assembly and a mass production.

As shown in fig. 3, in one embodiment, the main body 100 is provided with an arc wall coaxially disposed with the rotation shaft 300, and a plurality of positioning grooves 101 are formed on the arc wall. So, because the cambered surface wall sets up with pivot 300 is coaxial, through set up a plurality of constant head tanks 101 on the cambered surface wall, can be so that constant head tank 101 arranges around the axis of pivot 300.

Specifically, the main body 100 is a plastic member, and the groove wall of the positioning groove 101 is made of plastic, so that the groove wall of the positioning groove 101 has certain elasticity, and the damping effect generated by the elastic member 400 cooperating with the positioning groove 101 is more obvious.

Further, the rotating body 200 has an inner end portion 210 disposed adjacent to the seating groove 101, and the elastic member 400 is disposed on the inner end portion 210, and the inner end portion 210 is protruded into a concave region formed by the arc-shaped wall.

Specifically, the rotating body 200 includes an inner end 210 close to the positioning groove 101, and an outer end far from the positioning groove 101. The side of the cambered wall close to the inner end 210 is formed with an inner concave area. The inner end 210 extends into the concave area formed by the arc wall, so that the elastic element 400 can be close to the positioning groove 101, and the positioning part 410 can penetrate into different positioning grooves 101.

As shown in fig. 3, in one embodiment, the positioning grooves 101 include a first positioning groove 102 and a second positioning groove 103 respectively located at the head and tail ends of all the positioning grooves 101.

Further, the depth direction of the first slot 201 and the depth direction of the second slot 202 are arranged at an acute angle. Thus, when the first insertion portion 420 and the second insertion portion 430 are inserted into the first insertion groove 201 and the second insertion groove 202, respectively, the first insertion portion 420 and the second insertion portion 430 cooperate to form a structure for clamping the rotating body 200, thereby effectively preventing the elastic body from loosening from the rotating body 200.

The elastic member 400 may be a spring sheet, which may be made of elastic steel or elastic plastic.

Wherein, because the elastic member 400 itself has a certain elasticity, when the rotator 200 rotates, and the positioning portion 410 is switched to enter different positioning grooves 101, the positioning portion 410 can be deformed by the extrusion of the groove wall of the positioning groove 101, so that the elastic potential energy of the elastic member 400 is changed, and the operator can feel the damping effect. In the above-mentioned rotary connection structure, the elastic member 400 is used to cooperate with the positioning groove 101 to generate a damping effect, and the rotary connection structure has a simple structure, a low cost, and is easy to assemble and convenient for mass production.
