[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0021] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0022] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0023] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0024] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] according to Figures 1 to 3 As shown, the utility model is a cigarette packet turning coupling, which includes a connecting piece 1, a cross shaft and two groups of chain links 2.

[0026] The two ends of the connector 1 are provided with U-shaped openings, a group of ports of the cross shaft is connected to the U-shaped openings, and two groups of chain links 2 are respectively connected to the other group of ports of the cross shaft.

[0027] The end of the chain link 2 away from the cross shaft is provided with a connecting groove 4, and the connecting groove 4 is used to clamp the connecting shaft 9. A semicircular ring 3 is axially extended from the end face of the connecting groove 4, and a semicircular block 6 connected by bolts 8 is provided on the semicircular ring 3 to fix the connecting shaft 9 in the connecting groove 4.

[0028] The utility model changes the connection between the chain link 2 and the connecting shaft 9 into a key connection, and uses the semicircular ring 3 and the semicircular block 6 structure which are easy to disassemble, so that the disassembly and assembly between the coupling and the connecting shaft 9 are more convenient, and the maintenance time and difficulty are greatly reduced.

[0029] Furthermore, the two end faces where the semicircular ring 3 and the semicircular block 6 are in contact with each other are provided with connecting holes 7, and the connecting holes 7 are provided with the bolts 8. In implementation, the diameter of the connecting shaft 9 is larger than the diameter of the connecting groove 4 formed between the semicircular ring 3 and the semicircular block 6, so that the connecting shaft 9 and the connecting groove 4 are interference fit.

[0030] Furthermore, a keyway 5 is provided in the semicircular ring 3, and the semicircular ring 3 is connected to the connecting shaft 9 via a key. In implementation, the keyway 5 and the key make the connection between the connecting shaft 9 and the chain link 2 more stable.

[0031] Furthermore, the length of the keyway 5 is greater than the width of the semicircular ring 3 and extends into the connecting groove 4. By extending the length of the keyway 5, the key forms an integral structure with the semicircular ring 3 and the chain link 2. During the transmission process, the transmission force received by the key through the connecting shaft 9 is distributed to a part of the chain link 2, ensuring that the force between the semicircular ring 3 and the chain link 2 is uniform, and avoiding the problem that the semicircular ring 3 is easily broken due to the transmission between the connecting shaft 9.

[0032] Furthermore, the U-shaped openings at both ends of the connecting member 1 are symmetrically arranged, and the two groups of chain links 2 are symmetrically arranged, so that the disassembly and assembly between the connecting shaft 9 and the chain links 2 are oriented in the same direction, which is convenient for operators to maintain.

[0033] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
