The base 100 in the quick-release bend is fixed to the rack 10, and a first channel is in communication with the mounting channel 11, so that the cable inside the rack 10 can enter the first channel from the mounting channel 11.

[0042] The quick-release elbow includes a base 100 and an elbow assembly 200. The base 100 is provided with a first channel, and the base 100 is used to be connected with the rack 10. The base 100 is provided with a limiting portion 111 and a buckle 120 arranged at intervals with the limiting portion 111. The end of the buckle 120 moves between the clamping position and the avoiding position. The elbow assembly 200 has a second channel inside and communicates with the first channel. Among the base 100 and the elbow assembly 200, one is provided with a sliding block 211, and the other is provided with a sliding groove 130 in sliding cooperation with the sliding block 211. The extension direction of the sliding groove 130 is parallel to the arrangement direction of the limiting portion 111 and the buckle 120. When the end of the buckle 120 is located at the clamping position, the relative sliding of the elbow assembly 200 and the base 100 is limited.

[0043] The above structure is arranged, so that when the buckle 120 is located at the clamping position, the elbow assembly 200 can be limited to the base 100. After pressing the buckle 120, the elbow assembly 200 can be slid out of the base 100, so that the elbow assembly 200 can be separately disassembled, and the disassembly is convenient, and the maintenance efficiency is improved.

The above arrangement makes the base 100 realize the limitation of the elbow seat 210 in three-dimensional direction, and improves the stability of the relative position of the two.

[0047] In order to improve the insertion efficiency, in some embodiments, the buckle 120 is provided with a clamping portion 1211 and an avoiding portion 1212 arranged at intervals with the clamping portion 1211. Figure 3 and Figure 4As shown, the chute 130 is provided with a first avoiding gap 131 away from the sidewall of the base 100, and the elbow seat 210 is provided with a second avoiding gap 212. In the length direction of the chute 130, the length of the first avoiding gap 131 is H011, the length from the upper end of the first avoiding gap 131 to the entrance of the chute 130 is H012, the length of the second avoiding gap 212 is H021, and the length from the lower end of the second avoiding gap 212 to the lower end of the elbow seat 210 is H022; wherein H011 > H022, and H012 < H021. In use, the part from the upper end of the second avoiding gap 212 to the lower end of the elbow seat 210 is first put into the chute 130 from the first avoiding gap 131, and then is slid downward, when the lower end of the elbow seat 210 abuts against the limiting block 110, the buckle 120 is reset to abut against the upper end of the elbow seat 210.

[0048] In some embodiments, in combination Figure 4 As shown, the elbow assembly 200 includes an upper elbow 230 and a lower elbow 240, the upper elbow 230 includes an upper half seat 231 and an upper half pipe 232, the lower elbow 240 includes a lower half seat 241 and a lower half pipe 242, the upper elbow 230 and the lower elbow 240 are abutted, the upper half seat 231 and the lower half seat 241 form the elbow seat 210, and the upper half pipe 232 and the lower half pipe 242 form the elbow piece 220. Wherein the elbow piece 220 includes a horizontal pipe 221 and a vertical pipe 222, and the elbow piece 220 is divided by a horizontal plane passing through the axis of the horizontal pipe 221 to form the upper elbow 230 and the lower elbow 240. The above arrangement makes the elbow assembly 200 easy to open mold and reduces production cost.

[0049] In order to realize the connection of the base 100 and the rack 10, in combination Figure 6 As shown, the base 100 is provided with a second elastic arm 140 extending along the axis direction of the first channel, and the free end of the second elastic arm 140 is provided with a limiting protrusion 141 extending away from the first channel. The above arrangement makes the rack 10 clamped between the back of the base 100 and the limiting protrusion 141. Wherein the second elastic arm 140 has two to improve the stress stability of the base 100.

[0050] In order to facilitate the improvement of the protection range of the cable, in some embodiments, the elbow assembly 200 further includes a pipeline 300, and the pipeline 300 and the outlet of the elbow assembly 200 are inserted and matched. Wherein in combination Figure 5As shown, the pipeline 300 is a corrugated pipe, and the outer periphery of the pipeline 300 is provided with an annular groove, and the inner side wall at the outlet of the elbow assembly 200 is provided with an arc-shaped protrusion 223 which is matched with the annular groove. This kind of arrangement makes the corrugated pipe be able to be smoothly matched with the elbow assembly 200. In order to avoid the depth of the insertion assembly of the corrugated pipe and the elbow assembly 200 being too large, the inner side wall of the elbow assembly 200 is provided with a stop protrusion 224 which is abutted with the end of the pipeline 300. Specifically, the arc-shaped protrusion 223 and the limiting protrusion 141 are both arranged on the vertical pipe 222.
