[0032] Among them, the trough body 1 for protecting cables includes a bottom plate 11 for carrying the clamping unit 2 and protective plates 12 located on both sides of the bottom plate 11 for protecting the clamping unit 2. The bottom plate 11 is symmetrically and horizontally provided with a first receiving groove 13 for accommodating the connecting plate 14. A connecting plate 14 for limiting the protective plate 12 is arranged in the first receiving groove 13, and the connecting plate 14 is fixedly connected to the protective plate 12; the bottom plate 11 is horizontally provided with a first limiting hole 111 for accommodating the corrugated pipe 112 and the first elastic member 113. A corrugated pipe 112 for protecting the first elastic member 113 and a first elastic member 113 located inside the corrugated pipe 112 for driving the connecting plate 14 to displace along the first receiving groove 13 are arranged in the first limiting hole 111. Both ends of the corrugated pipe 112 and both ends of the first elastic member 113 are fixedly connected to the bottom plate 11 and the connecting plate 14 respectively.

[0033] Further, a connection hole 114 for accommodating the second connection block 115 is horizontally formed on one side of the bottom plate 11, and a second connection block 115 for connecting the bottom plate 11 is fixedly connected to the other side of the bottom plate 11. A receiving hole 116 for accommodating the second elastic member 117 and the clamping block 118 is vertically formed at the top of the second connection block 115. A second elastic member 117 for driving the clamping block 118 to displace along the receiving hole 116 and a clamping block 118 for limiting the bottom plate 11 are arranged in the receiving hole 116. One end of the second elastic member 117 is fixedly connected to the second connection block 115, and the other end of the second elastic member 117 is fixedly connected to the clamping block 118. A second limiting hole 119 for accommodating the clamping block 118 is vertically formed on one side of the top of the bottom plate 11, and the second limiting hole 119 communicates with the connection hole 114.

[0034] It should be noted that the first elastic member 113 and the second elastic member 117 are preferably springs, dampers, etc., and only springs are taken as examples in the drawings.

[0035] Operation process: When connecting adjacent bottom plates 11, press the clamping block 118 in the receiving hole 116 vertically formed on the second connection block 115 fixed to one side of the bottom plate 11, so that the second elastic member 117 is elastically deformed under force, thereby driving the clamping block 118 to slide into the receiving hole 116 along the inner wall of the receiving hole 116, moving the second connection block 115 along the inner wall of the connection hole 114 until the second connection block 115 completely enters the connection hole 114. At this time, the second elastic member 117 is released from the force and returns to its original state, pushing the clamping block 118 into the second limiting hole 119, thereby fixing the two bottom plates 11 and enabling adjacent bottom plates 11 to be quickly fixed.

[0036] Further, when replacing the bottom plate 11 or disassembling adjacent bottom plates 11, press the clamping block 118 in the second limiting hole 119, so that the second elastic member 117 is deformed under force, driving the clamping block 118 to move into the receiving hole 116, and then pulling out the second connection block 115 to disassemble, enabling adjacent bottom plates 11 to be quickly disassembled.

[0037] Further, the first elastic member 113 can drive the connecting plate 14 located in the first receiving groove 13 to displace under force, and the connecting plate 14 is fixedly connected to the protection plate 12, so that the protection plate 12 can be adjusted according to the required width of the cable trough, improving the applicable range of the cable trough.

[0038] Embodiment 2:

[0039] Refer to Figure 5 、 Figure 6, Figure 7 , the differences between this embodiment and the first embodiment are as follows: a clamping unit 2 for clamping the cable, a first connecting block 21 for fixing the clamping member 24, a through hole 22 for limiting the cable, a second receiving groove 23 for receiving the clamping member 24, a clamping member 24 for clamping the cable, an adjusting gear 241 for driving the limiting gear 243 to rotate, a limiting rod 242 for fixing the adjusting gear 241, a limiting gear 243 that rotates following the adjusting gear 241, a limiting ring 244 for limiting the adjusting piece 247, a third receiving groove 245 for receiving the connecting rod 246, a connecting rod 246 for driving the adjusting piece 247 to rotate, an adjusting piece 247 for clamping the cable, and a connecting shaft 248 for limiting the adjusting piece 247

[0040] Among them, the clamping unit 2 for clamping the cable is fixed to the top of the bottom plate 11. The clamping unit 2 includes a first connecting block 21 for fixing the clamping member 24. A through hole 22 for limiting the cable is horizontally formed on the first connecting block 21. And a second receiving groove 23 is vertically formed on the top of the first connecting block 21. The through hole 22 communicates with the second receiving groove 23. The clamping member 24 is disposed in the second receiving groove 23. The clamping member 24 includes an adjusting gear 241 located in the second receiving groove 23 for driving the limiting gear 243 to rotate. A limiting rod 242 for fixing the adjusting gear 241 is disposed through the adjusting gear 241. The limiting rod 242 is axially connected to the adjusting gear 241. And the limiting rod 242 is fixedly connected to the first connecting block 21.

[0041] Further, a limiting gear 243 that rotates following the adjusting gear 241 is disposed on one side of the adjusting gear 241. The limiting gear 243 meshes with the adjusting gear 241. The limiting gear 243 is hollow. Symmetrically disposed in the limiting gear 243 are limiting rings 244 for limiting the adjusting piece 247. The limiting rings 244 are fixedly connected to the first connecting block 21. Horizontally formed on both sides of the limiting gear 243 and on one side of the limiting ring 244 are a plurality of third receiving grooves 245 for receiving the connecting rod 246. Between the limiting gear 243 and the limiting ring 244 are provided a plurality of connecting rods 246 for driving the adjusting piece 247 to rotate. The connecting rods 246 are located in the third receiving grooves 245. And one end of the connecting rod 246 is axially connected to the limiting gear 243.

[0042] Further, a plurality of adjusting pieces 247 for clamping the cable are arranged inside the limit gear 243. The adjusting pieces 247 are located between the symmetrically arranged limit rings 244. The other end of the connecting rod 246 is pivotally connected to the adjusting piece 247. A plurality of connecting shafts 248 for limiting the adjusting piece 247 are arranged through the limit ring 244. The connecting shaft 248 penetrates through the limit ring 244 and the adjusting piece 247. The connecting shaft 248 is fixedly connected to the limit ring 244 and is pivotally connected to the adjusting piece 247.

[0043] The remaining structure is the same as that of the first embodiment.

[0044] Operation process: Rotate the adjusting gear 241 in the clamping member 24, so that the limit gear 243 in the adjusting gear 241 rotates, driving the connecting rod 246 located in the third receiving groove 245 to move. Since the adjusting piece 247 is pivotally connected to the connecting rod 246 and the connecting shaft 248 is pivotally connected to the adjusting piece 247, when the connecting rod 246 moves, the connecting rod 246 drives the adjusting piece 247 to rotate around the connecting shaft 248 as the center, so that the cable groove can be adjusted according to the thickness of the cable, avoiding the situation that the cable is too thick to be fixed. At the same time, when replacing cables of different models, there is no need to replace the cable groove, which is very convenient.

[0045] Working principle: When connecting adjacent bottom plates 11, press the block 118 in the receiving hole 116 vertically opened on the second connecting block 115 fixed to one side of the bottom plate 11, so that the second elastic member 117 is elastically deformed under force, driving the block 118 to slide into the receiving hole 116 along the inner wall of the receiving hole 116, moving the second connecting block 115 along the inner wall of the connecting hole 114 until the second connecting block 115 completely enters the connecting hole 114. At this time, the second elastic member 117 is released from the force and returns to its original state, pushing the block 118 into the second limiting hole 119, thereby fixing the two bottom plates 11, enabling adjacent bottom plates 11 to be quickly fixed.

[0046] Further, the first elastic member 113 can drive the connecting plate 14 located in the first receiving groove 13 to displace under force, and the connecting plate 14 is fixedly connected to the protection plate 12, so that the protection plate 12 can be adjusted according to the required width of the cable groove, improving the applicable range of the cable groove.

[0047] Further, rotate the adjustment gear 241 in the clamping member 24 to cause the limit gear 243 in the adjustment gear 241 to rotate, driving the connecting rod 246 located in the third receiving groove 245 to move. Since the adjusting piece 247 is pivotally connected to the connecting rod 246 and the connecting shaft 248 is pivotally connected to the adjusting piece 247, when the connecting rod 246 moves, the connecting rod 246 drives the adjusting piece 247 to rotate around the connecting shaft 248 as the center, so that the cable trough can be adjusted according to the thickness of the cable, avoiding the situation where a thicker cable cannot be fixed. At the same time, when replacing cables of different models, there is no need to replace the cable trough, which is very convenient.

[0048] Further, when replacing the bottom plate 11 or disassembling adjacent bottom plates 11, press the block 118 located in the second limiting hole 119 to cause the second elastic member 117 to deform under force, driving the block 118 to move into the receiving hole 116, and then pulling out the second connecting block 115, and it can be disassembled, so that the adjacent bottom plates 11 can be quickly disassembled.
