Referring to Figs. 1 to 12, in the present embodiment, the rotating connection structure includes a fixed member 11 and a rotating member 12 rotating relative to the fixed member 11 within a predetermined working angle range.
The fixed member 11 is provided with a rotating shaft groove 111, a mounting groove 112 and a limiting groove 113. It should be noted here that the rotating shaft groove 111 and the mounting groove 112 are in communication with each other, and the mounting groove 112 should have a greater radial size than the rotating shaft groove 111; the limiting groove 113 is designed to have an arc shape, and radians spanned by the limiting groove 113 should be not less than the preset working angle range of the rotating member 12. The rotating shaft groove 111 and the mounting groove 112 provided in the fixed member 11 are configured to realize a connection with the rotating member 12, and the limiting groove 113 provided in the fixed member 11 is configured to limit slide and rotation of the rotating member 12.
The rotating member 12 includes a main body 121, a limiting member 122, a rotating shaft 123 connected to the main body 121, and a head 124 connected to the rotating shaft 123. It should be noted here that a rotating axis 123 of the rotating member 12 is located at a central axis of the rotating shaft 123 connected to the main body 121 of the rotating member 12; a center of the head 124 connected to the rotating shaft 123 should coincide with a center of the rotating shaft 123, such that the head 124 and the rotating shaft 123 are uniformly stressed after the rotating connection is realized; a radial size of the head 124 should be less than a radial size of the mounting groove 112 to enable the head 124 to pass through the mounting groove 112, and should be greater than a radial size of the rotating shaft groove 111 to enable the head 124 to be blocked outside the rotating shaft groove 111; a radial size of the rotating shaft 123 should be less than the radial size of the rotating shaft groove 111, such that the rotating shaft 123 may slide in the rotating shaft groove 111; a radial size of the limiting member 122 should be less than the radial size of the limiting groove 113, such that the limiting member 122 may slide in the limiting groove 113; a center distance between the limiting member 122 and the rotating shaft 123 should be within a range of the maximum distance between the limiting groove 113 and the rotating shaft groove 111, such that the limiting member 122 may be limited in the limiting groove 113 before the rotating shaft 123 slides to an end of the rotating shaft groove 111.
The head 124 passes through the mounting groove 112 and makes the rotating shaft 123 slide from the mounting groove 112 into the rotating shaft groove 111, the rotating shaft 123 may rotate in the rotating shaft groove 111, the head 124 is stopped outside the rotating shaft groove 111, and the head 124 and the main body 121 are located on two opposite sides of the fixed member 11; the limiting member 122 is elastically deformed when the rotating shaft 123 slides from the mounting groove 112 towards the rotating shaft groove 111, and recovers from the elastic deformation and is limited in the limiting groove 113 when the rotating shaft 123 slides into the rotating shaft groove 111, and a sliding range of the limiting member 122 in the limiting groove 113 includes the preset working angle range of the rotating member 12.
It should be noted here that, when the rotating member 12 and the fixed member 11 are mounted, referring to Fig. 10 first, the head 124 of the rotating shaft 123 is inserted through the mounting groove 112, and then, the rotating shaft 123 is slid from the mounting groove 112 into the rotating shaft groove 111, such that the head 124 of the rotating shaft 123 and the main body 121 are located on two opposite sides of the fixed member 11 respectively, and when the rotating shaft 123 is slid from the mounting groove 112 towards the rotating shaft groove 111 and the limiting member 122 does not yet reach the limiting groove 113, the limiting member 122 is elastically deformed in a direction away from the fixed member 11; then, referring to Fig. 11, when the rotating shaft 123 is slid from the mounting groove 112 towards the rotating shaft groove 111 and the limiting member 122 reaches the limiting groove 113, the limiting member 122 recovers from the elastic deformation and is limited in the limiting groove 113, and at this point, the rotating member 12 and the fixed member 11 may be mounted; specifically, referring to Fig. 12, the rotating member 12 may rotate around the rotating shaft 123 within a range limited by the limiting groove 113. It should be further noted here that, when the rotating connection structure is required to be disassembled, the limiting member 122 may be pushed out of the limiting groove 113 by elasticity of the limiting member 122 to release a limiting relationship, and then, the head 124 is withdrawn from the mounting groove 112 after the rotating shaft 123 of the rotating member 12 is slid back from the rotating shaft groove 111 to the mounting groove 112, so as to disassemble the rotating connection structure without damaging the rotating connection structure.
In the rotating connection structure according to the embodiment of the present application, the rotating connection is realized by inserting the head 124 of the rotating shaft 123 through the mounting groove 112, then sliding the head 124 into the rotating shaft groove 111 and limiting the limiting member 122 in the limiting groove 113, and the disassembly may be subsequently realized by pushing the limiting member 122 out of the limiting groove 113, sliding the head 124 of the rotating shaft 123 back to the mounting groove 112 and pushing the head 124 out, such that the rotating connection structure is convenient to disassemble and assemble, may be disassembled and assembled repeatedly, and is not prone to damage, thus facilitating subsequent disassembly, assembly and maintenance.
Referring to Fig. 2, in another embodiment of the present application, the rotating shaft groove 111, the mounting groove 112 and the limiting groove 113 are in communication with one another. Specifically, on the basis that the mounting groove 112 and the rotating shaft groove 111 are in communication with each other, the limiting groove 113 is provided close to the mounting groove 112, the limiting groove 113 and the mounting groove 112 are in communication with each other, and an overall radial size of the limiting groove 113 and the mounting groove 112 should be greater than the radial size of the head 124 of the rotating shaft 123, such that the head 124 of the rotating shaft 123 passes through the mounting groove 112; the other side of the limiting groove 113 away from the side in communication with the mounting groove 112 should be disposed in an arc shape, and the radians spanned by the limiting groove 113 should be not less than the preset working angle range of the rotating member 12. Based on this structure, the limiting member 122 and the rotating shaft 123 have a small center distance, and in the mounting process, the limiting member 122 may be limited in the limiting groove 113 only by generating small elastic deformation.
Referring to Fig. 3, in another embodiment of the present application, the rotating shaft groove 111 is in communication with the mounting groove 112, and the limiting groove 113 and the mounting groove 112 are separately disposed independently. Specifically, the rotating shaft groove 111 is in communication with the mounting groove 112, so as to allow the head 124 of the rotating shaft 123 to pass through the mounting groove 112 and then slide into the rotating shaft groove 111, such that the head 124 of the rotating shaft 123 and the main body 121 of the rotating shaft 123 are located on two opposite sides of the fixed member 11 respectively; the limiting groove 113 and the mounting groove 112 are separately disposed independently, and the center distance between the limiting member 122 and the rotating shaft 123 should be within the range of the maximum distance between the limiting groove 113 and the rotating shaft groove 111, such that the limiting member 122 may be limited in the limiting groove 113 before the rotating shaft 123 slides to the end of the rotating shaft groove 111. Based on this structure, the separate and independent arrangement of the mounting groove 112 and the limiting groove 113 facilitates a processing operation and easily guarantees size precision of the mounting groove 112 and the limiting groove 113.
Referring to Figs. 4 to 6, in another embodiment of the present application, the limiting member 122 includes an elastic sheet 1221 and a limiting protrusion 1222, the elastic sheet 1221 has a first end and a second end opposite to the first end, the first end of the elastic sheet 1221 is connected to the main body 121 of the rotating member 12, the second end of the elastic sheet 1221 is configured as a free end, and the limiting protrusion 1222 is provided at the second end and limited in the limiting groove 113.
