[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-5 As shown, the retractable wire trough snap-in connection device proposed by the present invention includes a retractable connecting square tube 5. The retractable connecting square tube 5 is made of a silver-gray, highly ductile, and corrosion-resistant alloy material. The two ends of the retractable connecting square tube 5 are respectively provided with a connected wire trough A1 and a connected wire trough B6. The retractable part of the retractable connecting square tube 5 can be adjusted according to the height and angle position of the connected wire trough A1 and the connected wire trough B6 at both ends. ，The degree of expansion and contraction and the degree of bending can be freely adjusted to complete the connection of the connected wire trough A1 and the connected wire trough B6. Compared with the connection of traditional connecting pieces, the retractable connecting square tube 5 can realize the connection of adjacent wire troughs that are not in the same horizontal line, which can effectively solve the problem of uneven alignment of adjacent wire troughs, reduce the time spent on adjusting the height, and improve the installation efficiency. The connected wire trough A1 is provided with a wire trough cover A2, and the connected wire trough B6 is provided with a wire trough cover B7. The top and side edges of the wire trough cover A2 and the wire trough cover B7 are both provided with fixed buckle II type 8. A second snap hole is provided at the inner curved portion of the top of A1 and the connected wire trough B6 and at the top edges of the wire trough cover A2 and the wire trough cover B7. The mounting end of the fixed snap type II 8 is installed corresponding to the second snap hole. The connected wire trough A1 and the connected wire trough B6 at both ends of the telescopic connecting square tube 5 and the wire trough cover A2 and the wire trough cover B7 can be fixed through the second snap hole by the fixed snap type II 8. Compared with the traditional bolt and nut fixing of the wire trough and the cover, the setting of the fixed snap type II 8 simplifies the installation process and greatly saves the installation time on the construction site.The top of the wire trough cover A2 of the connected wire trough A1 and the wire trough cover B7 of the connected wire trough B6 are both provided with a fixed buckle type Ⅰ 3. The top of the wire trough cover A2 of the connected wire trough A1 and the wire trough cover B7 of the connected wire trough B6 and the top of the retractable connecting square tube 5 are both provided with a buckle hole 1. The mounting end of the fixed buckle type Ⅰ 3 is installed corresponding to the buckle hole 1. The fixed buckle type Ⅰ 3 is connected to the wire trough cover A2 of the connected wire trough A1 and the wire trough B6 through the buckle hole 1. The slot cover B7 is fixed with the retractable connecting square tube 5 by snapping. Both sides of the connected wire trough A1 and the connected wire trough B6 are provided with fixed snap type Ⅲ 4. The two sides of the connected wire trough A1 and the connected wire trough B6 are provided with snap holes 3 at positions corresponding to the two sides of the retractable connecting square tube 5. The mounting end of the fixed snap type Ⅲ 4 is installed corresponding to the snap hole 3. The setting of the fixed snap type Ⅲ 4 can fix the connected wire trough A1 and the connected wire trough B6 with the retractable connecting square tube 5 through the snap hole 3. Compared with the screw connection commonly used in traditional cable duct connection, the setting of fixed clip type I 3 and fixed clip type III 4 can complete the connection of adjacent cable ducts in a very short time, saving a lot of time and labor costs. At the same time, it can effectively avoid the interference of screws on the wires in the cable duct. The structural form of fixed clip type I 3, fixed clip type III 4 and fixed clip type II 8 is the same. The fixed clip type I 3 and fixed clip type III 4 are the same size. The sizes of the Type I clip 3 and the Type II fixed clip 8 are different. The Type I, Type III, and Type II fixed clips 8 are made of a silver-gray, high-strength, high-toughness alloy. When the retractable connecting square tube 5 is connected to the connected cable ducts A1 and B6 at both ends and the cable duct covers A2 and B7 through the Type I, Type III, and Type II fixed clips 8, the cables in the cable duct are completely sealed, providing corrosion and rust prevention.

[0021] In this embodiment, when the operator needs to connect two adjacent cable troughs, he first adjusts the retractable part in the middle of the retractable connecting square tube 5 to correspond to the height and position of the two groups of cable troughs, and then fixes the connected cable trough A1 and the connected cable trough B6 to the retractable connecting square tube 5 through the fixing buckle type III 4, and then passes the wires of the two groups of cable troughs through the retractable connecting square tube 5 so that the wires are located on the inner side of the connected cable trough A1 and the connected cable trough B6. Then, the operator uses the fixing buckle type II 8 to fix the cable trough cover A2 and the cable trough cover B7 to correspond to each other above the connected cable trough A1 and the connected cable trough B6. Finally, the cable trough cover A2 of the connected cable trough A1 and the cable trough cover B7 of the connected cable trough B6 are fixed to the retractable connecting square tube 5 through the fixing buckle type I 3, so that the cable trough is in a closed state, thereby completing the connection operation of the two adjacent cable troughs.

[0022] The above specific embodiment is only a preferred embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
