[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figure 1 - Figure 3As shown in the figure, the utility model provides an insulating copper protection shell for an intermediate joint, which includes a shell body 1 and a second connecting wire 5. One end of the shell body 1 is fixedly connected with a second rotating block 2. One end of the second rotating block 2 is provided with a driving block 3. The inner side of the driving block 3 is rotatably connected with a first connecting wire 4. The inner cavity of the shell body 1 is provided with a first joint 14. A spring 12 is sleeved on the outer surface of the first joint 14. One end of the first joint 14 is fixedly connected with a first rotating block 15. Two inclined surfaces 16 are arranged at one end of the first rotating block 15. The inner side of the second rotating block 2 is rotatably connected with a driving block 21. The driving block 21 is rotatably connected with the inner wall of the shell body 1. One end of the driving block 21 is fixedly connected with a pushing block 22. One end of the pushing block 22 is located inside the first rotating block 15. A connecting groove 24 is formed at one end of the driving block 21. A plugging block 23 is fixedly connected to the inner cavity of the connecting groove 24.

[0025] Specifically, the specific settings and functions of this embodiment are described below. During the connection operation, rotating the driving block 3 can drive the driving block 21 to rotate synchronously. As the driving block 21 rotates, the pushing block 22 thereon will abut against the inclined surface 16, thereby driving the first rotating block 15 to move. The driving force generated by this rotation enables the first rotating block 15 to drive the first joint 14 to move together until one end of the first joint 14 is pushed out of the inner cavity of the shell body 1. This greatly facilitates the plugging process of the second joint 51 and the first joint 14, and also simplifies the wiring steps of the circuit. After the wiring is completed, just align and connect the plugging ring 61 with the plugging groove 13 to achieve the stable connection of the connecting block 6 and the shell body 1.

[0026] Furthermore, if the driving block 21 continues to rotate, the first rotating block 15 will continue to rotate. During this process, since the first rotating block 15 has compressed the spring 12 when pushing the first joint 14 out of the shell body 1 before, as the first rotating block 15 continues to rotate, under the action of the elastic restoring force of the spring 12, the first rotating block 15 will gradually reset. This reset process will drive the first joint 14 and the second joint 51 to move back into the inner cavity of the shell body 1 together, which not only facilitates the completion of the wiring, but also provides effective insulation protection for the wiring part through the shell body 1, enhancing the safety of use.

[0027] Embodiment 2: As Figure 2 - Figure 4As shown, one end of the driving block 3 is fixedly connected to an adapter block 31, and the other end of the adapter block 31 is fixedly connected to a first connecting wire 4. One end of the adapter block 31 is inserted into the insertion groove 24, and the inner cavity of the adapter block 31 is inserted with an insertion block 23. One end of the housing main body 1 is provided with an insertion slot 13. A connecting block 6 is fixedly connected to the outer surface of the second connecting wire 5, and a plugging ring 61 is fixedly connected to one end of the connecting block 6. The plugging ring 61 is inserted into the insertion slot 13, and a second connector 51 is installed inside the plugging ring 61. One end of the second connector 51 is fixedly connected to the second connecting wire 5, and the other end of the second connector 51 is inserted into the first connector 14. Two sliding tracks 11 are symmetrically and fixedly connected to the inner wall of the housing main body 1. Sliding grooves 17 are respectively formed at the top and bottom of the first rotating block 15. The sliding grooves 17 are slidably connected to the sliding tracks 11, and the inclined surface 16 abuts against the pushing block 22.

[0028] The effect achieved by the entire embodiment is that by inserting one end of the driving block 3 into the inside of the insertion groove 24, the stable insertion of the insertion block 23 and the adapter block 31 can be realized. This not only plays a driving role but also ensures the effective connection of the internal circuit. During the driving process, the rotation of the driving block 3 will drive the adapter block 31 to rotate synchronously. The adapter block 31 then exerts a rotational force on the insertion block 23, causing the active block 21 to start rotating. The active block 21 rotates freely under the guidance of the second rotating block 2, ensuring the stability and smoothness of the rotation.

[0029] At the same time, when the insertion block 23 rotates, it pushes the first rotating block 15 to move through the interaction between the pushing block 22 and the inclined surface 16. During this process, relative sliding occurs between the sliding grooves 17 and the sliding tracks 11, and their coordinated action ensures that the first rotating block 15 only moves linearly, thus maintaining the stability of the overall structure and the accuracy of the movement.

[0030] The usage method and working principle of this device: Insert one end of the driving block 3 accurately into the inside of the insertion groove 24 to achieve seamless insertion between the insertion block 23 and the adapter block 31. When starting the driving process, by rotating the driving block 3, this action is converted into the synchronous rotation of the adapter block 31. As a key component for power transmission, the rotational movement of the adapter block 31 is transmitted to the insertion block 23 through a precise mechanical structure, and then a necessary driving force is applied to the active block 21 to control its start of rotation.

[0031] As the active block 21 rotates, the pushing block 22 thereon begins to come into close contact with the inclined plane 16 and interact with it. The rotational motion is converted into a linear driving force to drive the first rotating block 15 to move along a preset trajectory. During this process, the first rotating block 15 not only moves itself, but also drives the first joint 14 to move together through its structural characteristics until one end of the first joint 14 is successfully pushed out of the inner cavity of the housing body 1. The completion of this step greatly simplifies the plugging process between the second joint 51 and the first joint 14, making the wiring work of the circuit more convenient and efficient.

[0032] When the first joint 14 and the second joint 51 are successfully plugged together, it is easy to align and connect the plugging ring 61 with the plugging groove 13 on the housing body 1. The completion of this step not only ensures the stable connection between the connecting block 6 and the housing body 1, but also further enhances the structural integrity and electrical stability of the entire system.

[0033] It is worth mentioning that after the wiring work is completed, the user can continue to rotate the active block 21. At this time, the first rotating block 15 begins to reset under the elastic restoring force of the spring 12. During the reset process, the first rotating block 15 will drive the first joint 14 and the second joint 51 to move back into the inner cavity of the housing body 1 together. This design not only protects the wiring from interference and damage from the external environment, but also provides additional safety protection for the entire system through the insulation performance of the housing body 1.

[0034] The above description is only a preferred embodiment of the present invention, and is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
