[0002] Wire trough connection refers to connecting two sections of wire trough in the wire trough wiring system to form a continuous channel to facilitate the laying of cables or wires. Wire troughs are usually used in interior decoration, electrical wiring, network wiring and other occasions to protect wires from damage, and also serve as beautification and decoration.

[0003] When the wire turns a corner, the required connecting device has a certain angle to perfectly connect the cable duct. In addition, there may be horizontal or vertical differences between adjacent cable ducts during the lifting process, so that they are not in the same direction (there is a height difference between the upper and lower parts). If the connecting device cannot eliminate such height differences, normal connecting operations cannot be performed. Therefore, it is necessary to design a cable duct connecting device that can make a certain angle. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1The utility model provides a technical solution: it includes a wire trough 1 and a connecting piece 2, the connecting piece 2 is fixed to one end of the wire trough 1 and is symmetrically distributed, an outer turntable 3 and an inner turntable 4 are respectively fixed to the adjacent side of the connecting piece 2, the outer turntable 3 is rotatably connected to the outside of the inner turntable 4 through a central rotating shaft 31, a trough cover 6 is fixed to the upper end of the wire trough 1 and the connecting piece 2, a corrugated connecting cover 7 is fixed between the adjacent ends of the trough cover 6, a positioning component is arranged between the outer turntable 3 and the inner turntable 4, an anti-slip pad 5 is fixed to the adjacent side of the outer turntable 3 and the inner turntable 4, a pair of fixing holes 21 are opened on the connecting piece 2, and the fixing holes 21 are long strip structures.

[0019] The positioning assembly includes a fixed block 43 and a fixed groove 37. The fixed block 43 is installed on the outside of the inner rotating head 4 and is equidistantly distributed around the circumference. The fixed groove 37 is arranged on the inside of the outer rotating head 3 and is aligned with one of the fixed blocks 43. The fixed block 43 extends out and is inserted into the fixed groove 37. A telescopic groove 41 is arranged in the inner rotating head 4 at a position corresponding to the fixed groove 37. A telescopic block 42 is slidably connected in the telescopic groove 41. The telescopic block 42 is fixed to one end of the inner side of the fixed block 43. The telescopic block 42 is fixed to the telescopic block 43. An ejection spring 44 is fixed between the inner walls of the groove 41, a pressing groove 32 is opened on the outer side of the outer rotating head 3 and at a position corresponding to the fixed groove 37, a pressing plate 33 is slidably connected in the pressing groove 32, a push rod 36 is fixed at the center position of the pressing plate 33, and the end of the push rod 36 is located in the fixed groove 37, a return spring 34 is fixed between the pressing plate 33 and the inner wall of the pressing groove 32, a positioning block 35 is fixed in the pressing groove 32, and the distance between the positioning block 35 and the bottom of the fixed groove 37 is equal to the length of the push rod 36.

[0020] Working principle: First, press the pressing plate 33, and under the condition of compressing the reset spring 34, push the push rod 36 to move inward, so that the end of the push rod 36 extends into the fixing groove 37, and pushes the end of the fixing block 43 out of the fixing groove 37, releases the fixation between the outer rotating head 3 and the inner rotating head 4, and then rotates the wire groove 1 so that it can be rotated to any angle. In this process, the expansion and contraction of the corrugated connecting cover 7 can ensure that the groove cover 6 is always sealed, so that the internal wire is always in a relatively sealed environment. After rotating to the specified position, the pressing block can be released to make the pressing plate 33 and the push rod 36 are reset, so that the fixing block 43 is reinserted into the corresponding fixing groove 37 to complete the fixing of the specified angle. During the whole process, the positioning block 35 can be used to limit the pressing distance of the push rod 36, so as to ensure that the end of the push rod 36 is located at the connection between the outer rotating head 3 and the inner rotating head 4 without affecting the normal rotation. At the same time, when the fixing block 43 is pushed out from the fixing groove 37, the telescopic block 42 can be driven to be extended and retracted, and the ejection spring 44 can be compressed. Therefore, after the push rod 36 is reset, the ejection spring 44 can be used to reset to drive the fixing block 43 to extend again and insert it into the fixing groove 37.
