Photovoltaic power generation is clean, renewable, and environmentally friendly, and is an important renewable energy source. In order to transmit the electricity generated by photovoltaic power generation, people will lay photovoltaic cables. When laying photovoltaic cables, in order to protect the safety of the cables and prevent the cables from being damaged when exposed to the outside, cable sleeves will be sheathed on the outside of the cables. Pipe joints are usually used to connect the cable sleeves used to protect the cables. The cable sleeves spliced ​​and connected by pipe joints can meet the purpose of changing with the length of the cable.

[0031] The driving unit 200 includes a driving component 201 that is sleeved on the middle section of the connecting component 101, a plug-in component 202 that is arranged on both sides of the driving component 201, and a sleeve component 203 that is symmetrically sleeved on the connecting component 101 and whose outer side surface is fixedly connected to the inner side surface of the adjusting component 103. The driving component 201 is rotatably connected to the connecting component 101, and two groups of driving components 201 are plug-in and slidably connected to the driving component 201, and can slide horizontally along the driving component 201, and at the same time, are limited in the circumferential direction of the driving component 201 and can rotate around the connecting component 101 with it.

[0032] During use, the connecting unit 100 is placed as a whole between the two sleeves, the connecting parts 102 at both ends of the connecting unit 100 are respectively inserted into the corresponding sleeves, the plug-in part 202 on the driving part 201 is slidably inserted into the sleeve part 203, and then the driving part 201 is rotated. The driving part 201 will drive the sleeve part 203 to rotate through the plug-in part 202, and the rotating sleeve part 203 will drive the adjusting part 103 to rotate synchronously, and now drive the corresponding limiting part 104 to expand outward in the connecting part 102. The outward expanding limiting part 104 can firmly abut against the inner wall of the sleeve, thereby tightly connecting the device and the sleeve together, and the limiting parts 104 on both sides act synchronously, which can achieve the purpose of connecting and fixing the two pipes through the connecting device.

[0033] Example 2

[0034] Reference Figure 2-Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the fixed connection fixed range can be adjusted accordingly according to the size of the sleeve to be connected, so as to meet the connection work requirements between pipes of different sizes.

[0035] Compared with Example 1, further, the connecting component 101 includes a connecting tube 101a located between the two groups of connecting components 102, and limiting rings 101b symmetrically sleeved on the connecting tube 101a in groups of two, the driving component 201 is sleeved between the limiting rings 101b in groups of two, the adjusting component 103 and the sleeve component 203 are located between the outer limiting ring 101b and the bottom surface of the connecting component 102, the driving component 201, the sleeve component 203 and the adjusting component 103 are all limited by the limiting ring 101b, and can only perform circular rotation on the connecting tube 101a with a constant horizontal position.

[0036] Among them, the connecting component 102 includes a plurality of groups of connecting heads 102a annularly distributed at both ends of the connecting pipe 101a, a limiting groove 102b located between every two groups of connecting heads 102a and a limiting component 104 slidably connected in the limiting groove 102b, and a limiting block 102c arranged on the outer side of the bottom end between every two groups of connecting heads 102a. The limiting component 104 located in the limiting groove 102b is limited from both sides and can only slide horizontally along the limiting groove 102b, while the limiting block 102c will limit the limiting component 104 from above, so that the limiting component 104 cannot be detached from the limiting groove 102b.

[0037] The connecting component 102 is a hollow truncated cone structure as a whole, and the diameter of the truncated cone structure gradually decreases from the end of the connecting pipe 101a to the outside, and the diameter of each section of the truncated cone structure of the connecting component 102 in the horizontal direction is different.

[0038] During use, the structure of the truncated cone is approximately conical, which can facilitate the insertion of the connecting component 102 into the sleeve, and the different diameters at each end of the truncated cone structure can meet the requirements of being inserted into sleeves of different sizes, thereby playing the role of initially connecting sleeves of different sizes with the device, and facilitating the device to carry out the next step of connection.

[0039] Among them, the adjusting component 103 includes an adjusting ring 103a which is sleeved on the connecting pipe 101a, and a spiral rack 103b which is arranged on the outer surface of the adjusting ring 103a and has a spiral structure. The spiral rack 103b is meshed with the bottom surface of the limiting component 104. The spiral rack 103b of the spiral spiral structure has 2 spiral turns, and the position of each section of the spiral structure and the distance to the center of the adjusting ring 103a are different.

[0040] The limiting components 104 are in an L-shaped structure as a whole, six limiting components 104 form a group, and each group of connecting components 102 includes two groups of limiting components 104 .

[0041] Among them, the limiting component 104 includes a fixing rod 104a located in the limiting groove 102b, and the fixing rod 104a is parallel to the bottom surface of the limiting groove 102b, an engaging tooth 104b is provided on the bottom surface of the fixing rod 104a, and the engaging tooth 104b is engaged with the spiral rack 103b, and an abutment rod 104c is vertically arranged at the inner end of the fixing rod 104a, and a barb for increasing friction is arranged on the outer side of the top end of the abutment rod 104c, which can increase the lateral resistance and friction between the abutment rod 104c and the inner wall of the sleeve, and further enhance the connectivity between the device and the sleeve.

[0042] During use, according to the size of the sleeve to be connected, the connecting component 102 is first inserted into the sleeve, and then the adjusting component 103 is driven to rotate by the driving unit 200. The adjusting component 103 will drive the spiral rack 103b set on the outside thereof to move synchronously, and the moving spiral rack 103b will push the fixing rod 104a to slide along the bottom surface of the limiting groove 102b through the engagement of the meshing teeth 104b, thereby driving the limiting component 104 as a whole to expand outward with the axis of the connecting component 102 as the origin. With continuous movement, the abutment rod 104c will eventually abut against the inner wall of the sleeve, and the multiple sets of limiting components 104 are synchronously driven by the spiral rack 103b to expand. Therefore, the connecting unit 100 can abut against the inner wall of the sleeve from the inside to the outside from multiple directions through the multiple sets of limiting components 104, and is firmly connected to the sleeve under the mutual action of the multiple sets of limiting components 104. By controlling the number of turns of the adjusting component 103, the function of adjusting the expansion amplitude of the limiting component 104 can be realized, thereby meeting the working requirements applied to sleeves of different sizes.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3

[0045] Reference Figure 2-Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the parts where the two ends of the device are connected to the sleeve can be adjusted in size synchronously or individually according to needs, so as to achieve the purpose of meeting the connection requirements between two groups of pipes of different sizes.

[0046] Compared with Example 2, further, the driving component 201 includes a driving ring 201a which is sleeved on the middle section of the connecting pipe 101a and limited by the limiting ring 101b, and a limiting slide groove 201b which is symmetrically opened on the driving ring 201a and has a convex structure in cross section, the lower end width of the limiting slide groove 201b is greater than the upper end width, and the plug-in component 202 is slidably connected in the limiting slide groove 201b.

[0047] Among them, the plug-in component 202 includes a dial plate 202a located in the limiting slide groove 201b, and the dial plate 202a extends outward into the socket component 203, and a limiting push block 202b is arranged at the center position above the dial plate 202a. One end of the dial plate 202a is flush with one end of the limiting push block 202b, and the other end is longer than the limiting push block 202b. By sliding the dial plate 202a in the limiting slide groove 201b, the extension distance of the dial plate 202a can be controlled, thereby controlling the insertion and removal of the dial plate 202a in the push groove 203b.

[0048] Among them, the sleeve component 203 includes a ring 203a sleeved on both sides of the connecting tube 101a, a push groove 203b symmetrically opened in the ring 203a, and the dial plate 202a extends into the push groove 203b, and an abutment block 203c is arranged between the head and tail of the two groups of push grooves 203b. The abutment block 203c separates the two groups of push grooves 203b. When the dial plate 202a slides along the push groove 203b, it will abut against the abutment block 203c.

[0049] During use, by sliding the plug-in component 202 along the limiting sliding groove 201b, one end of the dial plate 202a can be inserted into the pushing groove 203b. The plug-in component 202 is limited by the driving component 201 as a whole. Therefore, when the driving component 201 rotates, it will drive the plug-in component 202 to rotate, and the rotating plug-in component 202 will push the dial plate 202a to slide in the pushing groove 203b. The sliding dial plate 202a will eventually abut against the abutment block 203c, and push the sleeve component 203 to rotate as a whole by abutting against the abutment block 203c, thereby realizing the function of driving the adjusting component 103 to rotate;

[0050] The two sets of plug-in components 202 are both located on the driving component 201. Therefore, when the driving component 201 rotates, the plug-in components 202 on both sides can be driven to synchronously drive the sleeve components 203 on both sides to rotate, thereby achieving the function of synchronously driving the adjusting components 103 on both sides to drive the limiting components 104 to expand;

[0051] The two groups of plug-in components 202 located on the driving component 201 are separately arranged on both sides of the driving component 201. When it is necessary to connect two groups of pipes of different sizes, firstly slide one group of plug-in components 202 along the limiting slide groove 201b and plug it into the corresponding sleeve component 203, and the other group is retracted on the driving ring 201a. At this time, only one side of the driving unit 200 as a whole is connected to the connecting unit 100, and the other side is not connected. Therefore, the limiting component 104 on one side can be adjusted separately; then, the plug-in component 202 inserted into the sleeve component 203 is retracted to disconnect it from the connecting unit 100. Corresponding to the connection of the adjustment component 103, the originally contracted plug-in component 202 is slid out of the limiting slide groove 201b to connect it with the corresponding sleeve component 203, and the adjustment operation of the limiting component 104 on the other side is realized. In summary, by adjusting and inserting different plug-in components 202, the limiting components 104 at both ends of the Unicom unit 100 can be controlled in steps, thereby meeting the need to adjust the corresponding sizes of the two ends of the connecting device separately when connecting two sleeves of different sizes, thereby achieving the function of connecting two pipes of different sizes, and further improving the flexibility of the device.

[0052] The remaining structure is the same as that of Example 2.
