[0023] The reciprocating autonomous connector of the present invention is as follows: Figure 1-4 As shown, it includes a rotary connection mechanism and a push-pull connection structure. The rotary connection mechanism includes a connecting sleeve 1, and a reciprocating rotating connecting body that can rotate is provided in the connecting sleeve 1. A push-pull connection structure is arranged between the reciprocating rotating connecting body and the connecting sleeve 1. The reciprocating rotating connecting body is axially locked relative to the connecting sleeve 1, wherein one end face of the connecting sleeve 1 is fixed on the device to be connected, and the reciprocating rotating connecting body can be positioned and installed in the connecting sleeve 1 by a bearing assembly or a rotating sleeve with ridges to realize its own rotation performance.

[0024] The telescopic movement of the push-pull connection structure in the connection sleeve 1 can realize the rotation drive of the reciprocating rotation connection body, such as Figure 6 As shown, the push-pull connection structure includes a connection plate 14, on which at least two connection rods 15 arranged circumferentially are provided, and at the ends of the connection rods 15 are provided with movable columns 16, and the connection plate 14 is fixedly mounted on another device to be connected.

[0025] like Figure 5 As shown, the reciprocating rotating connector includes a cylindrical body 4, with a first convex ring 2 and a second convex ring 3 respectively provided at both ends of the cylindrical body 4. The first convex ring 2 and the second convex ring 3 can realize synchronous rotation in the connecting sleeve 1.

[0026] like Figure 16 As shown, a plurality of first guide grooves arranged circumferentially are provided on the side of the first convex ring 2 close to the second convex ring 3, and each first guide groove includes a first inclined surface 5 and a first straight surface 7. Figure 17As shown, a plurality of second guide grooves arranged circumferentially are provided on the side surface of the second convex ring 3 close to the first convex ring 2, and each second guide groove includes a second inclined surface 8 and a second straight surface 10. A plurality of removal grooves 12 connected to the second guide grooves are also provided on the second convex ring 3, and the removal grooves 12 are arranged at intervals between the second guide grooves.

[0027] The moving-out through groove 12 corresponds to the first inclined surface 5, the first straight surface 7 corresponds to the second inclined surface 8, and the second inclined surface 8 corresponds to the first inclined surface 5. The number of the moving-out through grooves 12 is an integer multiple of the connecting rod 15, and the number of the first guide groove and the second guide groove is the same and both are twice the number of the moving-out through grooves 12, that is, there is a deflection angle along the axis between the first guide groove and the second guide groove.

[0028] Each connecting rod 15 is located between the connecting sleeve 1 and the convex ring. The movable column 16 at the end of the connecting rod 15 cooperates with the movable groove 12. The movable column 16 moved out of the movable groove 12 can enter the second guide groove through the guidance of the first guide groove, thereby realizing the axial connection between the push-pull connection structure and the reciprocating rotating connection body.

[0029] Furthermore, a first curved surface 6 is provided between the first inclined surface 5 and the first straight surface 7. The first curved surface 6 corresponds to the second inclined surface 8. A second curved surface 9 is provided between the second inclined surface 8 and the second straight surface 10, spaced apart from the removal slot 12. The second curved surface 9 corresponds to the first inclined surface 5. The second guide groove connected to the removal slot 12 includes a third inclined surface 11 and a third straight surface 13. The third inclined surface 11 corresponds to the first curved surface 6, and the third straight surface 13 corresponds to the first inclined surface 5. The movable post 16 also cooperates with the first curved surface 6 and the second curved surface 9.

[0030] The movable column 16 that moves out of the through groove 12 can enter the second guide groove through the guidance of the first guide groove, thereby realizing the axial connection between the push-pull connection structure and the reciprocating rotation connection body. Figure 7-15 The figure shows an example to illustrate the assembly and disassembly operation of the reciprocating autonomous connector, wherein the connecting sleeve 1 and the connecting plate 14 are respectively fixed on two devices to be connected, and the connecting sleeve 1 and the connecting plate 14 can move relative to each other in the axial direction.

[0031] like Figure 7 As shown, the movable column 16 on each connecting rod 15 can enter between the reciprocating rotating connecting body and the connecting sleeve 1 through the corresponding movable groove 12. The movable column 16 continues to move closer to the first convex ring 2, separates from the third inclined surface 11 and the third straight surface 13, and contacts the first inclined surface 5. Figure 8 As shown, if the movable column 16 continues to move inward, it will push the reciprocating rotating connector to rotate until it enters the first arc surface 6, as shown in FIG. Figure 9As shown, the moving column 16 stops moving inward, and then the moving column 16 is pulled outward and enters the second inclined surface 8 under the guidance of the first straight surface 7, as shown in FIG. Figure 10 As shown, continuing to pull out will drive the reciprocating rotating connector to continue rotating, and the moving column 16 will eventually enter the second arc surface 9, as shown in FIG. Figure 11 As shown, the movable column 16 cannot be pulled out, thereby realizing the axial connection between the reciprocating rotating connector and the push-pull connection structure.

[0032] When the reciprocating connector and push-pull connector need to be dismantled, Figure 11 On the basis of the connecting rod 15, the movable column 16 is driven to move telescopically, and when it moves into the connecting sleeve 1, as shown in FIG. Figure 12 As shown, it first separates from the second guide groove and contacts the first inclined surface 5, pushing the reciprocating rotating connector to rotate, as shown in FIG. Figure 13 As shown, it is finally located in the first arc surface 6 and when it is pulled out of the connecting sleeve 1, as shown in FIG. Figure 14 As shown, it contacts the third inclined surface 11, driving the reciprocating rotating connector to rotate, and finally Figure 15 As shown, the separation is achieved by pulling out the through groove 12.

[0033] During the above operation, the connecting sleeve 1 and each connecting rod 15 only perform axial relative movement and no relative rotation occurs. Through the telescopic movement of the connecting rod 15, the rotation of the reciprocating rotating connector inside the connecting sleeve 1 can be realized, thereby completing the axial connection and axial separation of the reciprocating rotating connector and the push-pull connection structure. The connection performance is firm and the disassembly and assembly operations are easy to achieve.

[0034] Furthermore, in order to realize the rotation of the reciprocating connecting body relative to the connecting sleeve 1 and to perform axial locking, a bearing 17 is installed between the first convex ring 2 and the connecting sleeve 1, the outer ring of the bearing 17 is fixedly connected to the connecting sleeve 1, and the inner ring of the bearing 17 is fixedly connected to the first convex ring 2.

[0035] Furthermore, in order to facilitate the insertion of one end of the connecting rod 15 with the movable column 16 between the reciprocating rotating connecting body and the connecting sleeve 1, reduce the matching accuracy requirements during operation, and make it easier to extend the connecting rod 15, a fourth inclined surface 18 is provided on the end of the connecting rod 15 away from the connecting plate 14, and an annular inclined surface 19 is provided on the inner circumference of the connecting sleeve 1 close to the second convex ring 3, which matches the fourth inclined surface 18. The outward-expanded annular inclined surface 19 and the fourth inclined surface 18 at the end of the connecting rod 15 can make it easier for the connecting rod 15 to enter the connecting sleeve 1, so as to facilitate subsequent reciprocating pulling to achieve axial locking and separation.

[0036] Furthermore, in order to improve the strength of the push-pull connection structure and ensure that the push-pull connection structure can drive the reciprocating rotating connection body to realize its own rotation under uniform force when it is extended and retracted, the connecting plate 14 is a circular ring plate, and eight connecting rods 15 arranged circumferentially are provided on the circular ring plate, eight removable grooves 12 and eight second guide grooves are provided on the second convex ring 3, and sixteen first guide grooves arranged circumferentially are provided on the first convex ring 2.

[0037] The reciprocating autonomous connector of the present invention connects and disconnects its two components through the reciprocating combination of the rotary connection mechanism and the push-pull connection structure. The reciprocating autonomous connector can be configured with varying numbers of connecting rods 15 and guide slots, depending on actual needs. During actual use, the two components of the present invention are securely connected to the two objects to be connected and disconnected, respectively, to move the objects to their destination.

[0038] The technical solutions of the present invention are not limited to the scope of the embodiments described in the present invention. The technical contents not described in detail in the present invention are all well-known technologies.
