Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire duct hangers, in particular to a bus duct hanger. Background Art
[0002] Cable trough, also known as wiring trough, distribution trough, and row cable trough, is an electrical tool used to organize power cables, data cables and other wires in a standardized manner and fix them on the wall or ceiling. Depending on the material, cable troughs are divided into many types, commonly used ones include environmentally friendly PVC cable troughs, halogen-free PPO cable troughs, halogen-free PC / ABS cable troughs, steel and aluminum and other metal cable troughs, etc.
[0003] At present, some existing cable duct hangers require the use of a ladder to climb to the side of the cable duct hanger when wiring, and the cables are manually moved and laid by personnel. However, the range of the personnel's arms is limited, which results in the personnel needing to frequently move the ladder and climb up multiple times when laying cables into the cable duct hanger. The wiring is relatively time-consuming and labor-intensive, and the use is relatively inconvenient. For this reason, we propose a bus duct hanger to solve or improve the above problems. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides a bus duct hanger, which solves the problems mentioned in the above background.
[0005] The utility model provides the following technical solution: it includes a wire trough, a first fixing frame fixed to the inner surface of the wire trough, a fixing plate fixed to the bottom of the first fixing frame, a pulley installed on the surface of the fixing plate through a rotating shaft, a connecting wire is sleeved on the surface of the pulley, a second fixing frame is fixed to the inner surface of the wire trough, a first limiting column is inserted into the inside of the second fixing frame, a buffer plate is fixed to the bottom of the first limiting column, a first spring is sleeved on the surface of the first limiting column, a clamping assembly is arranged on the surface of the connecting wire, and the clamping assembly can clamp the busbar.
[0006] Furthermore, the clamping assembly includes a fixed block fixed to the surface of the connecting line, a second limiting column fixed inside the fixed block, a second spring sleeved on the surface of the second limiting column, and a clamp slidably installed on the surface of the second limiting column.
[0007] Furthermore, connectors are fixed on the surface of the wire trough. Several groups of connectors are symmetrically fixed on the surface of the wire trough. Mounting rods are fixed on the tops of the connectors. The number of the mounting rods is the same as the number of the connectors.
[0008] Furthermore, a limiting plate is fixed on the surface of the first fixing frame, and the limiting plate is located on one side of the pulley.
[0009] Furthermore, a dust cover is placed on the top of the cable duct, and the dust cover is located between the groups of mounting rods.
[0010] Compared with the prior art, the present invention has the following beneficial effects: by arranging pulleys, connecting wires and clamping assemblies, the busbar cable can be laid inside the cable trough by clamping the cable between the fixed block and the clamping plate. At this time, by pulling the connecting wire, the connecting wire can be rotated through the two sets of pulleys and drive the fixed clamping assembly to move, so that the clamping assembly drives one end of the cable to move and move from one end of the cable trough to the other end, thereby passing the cable through the inside of the cable trough. There is no need for personnel to manually lay the cable inside the cable trough, thereby avoiding the problem of personnel having to frequently move the climbing ladder and climb multiple times when laying the cable in the cable trough. The wiring is relatively time-saving and labor-saving, and the use is relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-5, including a wire trough 1, a connecting piece 4 is fixed on the surface of the wire trough 1, and several groups of connecting pieces 4 are symmetrically fixed on the surface of the wire trough 1, a mounting rod 3 is fixed on the top of the connecting piece 4, and the number of mounting rods 3 is the same as the number of connecting pieces 4, a dust cover 2 is placed on the top of the wire trough 1, and the dust cover 2 is located between several groups of mounting rods 3. The dust cover 2 can block the top of the wire trough 1 to prevent dust and debris from entering the interior of the wire trough 1 from the top side of the wire trough 1, a first fixing frame 5 fixed to the inner surface of the wire trough 1, a fixing plate 6 fixed to the bottom of the first fixing frame 5, and two groups of fixing plates 6 are symmetrically fixed at the bottom of a group of first fixing frames 5, and a pulley 8 installed on the surface of the fixing plate 6 is rotated by a rotating shaft, and the first fixing frame 5 The surface of the limit piece 7 is fixed, and the limit piece 7 is located on one side of the pulley 8. The first fixed frame 5, the fixed plate 6, the limit piece 7 and the pulley 8 are symmetrically arranged in two groups inside the line slot 1. The connecting line 9 is sleeved on the surface of the pulley 8, and the connecting line 9 is sleeved on the surface of the two groups of pulleys 8 at the same time. When the pulley 8 rotates, it will drive the connecting line 9 sleeved on the surface to rotate. The limit piece 7 can limit the position of the connecting line 9 to reduce or prevent the limit piece 7 from falling off from the surface of the pulley 8. The clamping assembly is arranged on the surface of the connecting line 9, and the clamping assembly can clamp the busbar. When the connecting line 9 rotates, it will drive the clamping assembly arranged on the surface to move. The buffer assembly is arranged on the inner surface of the line slot 1, and the buffer assembly is located on the top side of the connecting line 9.
[0019] The clamping assembly includes a fixed block 11 fixed to the surface of the connecting line 9. When the connecting line 9 rotates, the fixed fixed block 11 will be driven to move. A second limiting column 18 is fixed inside the fixed block 11. When the fixed block 11 moves, the fixed second limiting column 18 will be driven to move. A second spring 17 is sleeved on the surface of the second limiting column 18. A clamping plate 12 is slidably mounted on the surface of the second limiting column 18. A limiting plate is fixed to the bottom of the second limiting column 18. The limiting plate can prevent the clamping plate 12 from detaching from the bottom side of the second limiting column 18. The second spring One end of 17 is fixed to the inner surface of the fixed block 11, and the other end is fixed to the top of the splint 12. When the splint 12 moves, it will drive one end of the second spring 17 to move, thereby stretching the second spring 17 to cause the second spring 17 to deform. When there is no external force interference, the second spring 17 will pull the splint 12 to move. A limiting rod is fixed to the bottom of the fixed block 11, and one end of the limiting rod passes through the interior of the splint 12 and is slidably connected to the splint 12. The limiting rod can limit the position of the splint 12 to prevent the splint 12 from rotating itself when moving.
[0020] The second fixing frame 13 is fixed to the inner surface of the wire groove 1, and the first limiting column 15 is inserted into the second fixing frame 13. Two groups of first limiting columns 15 are symmetrically inserted in the interior of the second fixing frame 13. A limiting plate is fixed on the top of the first limiting column 15. The limiting plate can limit the position of the first limiting column 15 to prevent the first limiting column 15 from escaping from the interior of the second fixing frame 13 from the bottom side of the second fixing frame 13. The buffer sheet 16 is fixed to the bottom of the first limiting column 15. The bottom of the buffer sheet 16 is provided with a groove. The connecting line 9 passes through the inside of the groove. The first spring 14 is sleeved on the surface of the first limiting column 15. The first spring 1 The number of 4 is the same as the number of the first limiting columns 15. One end of the first spring 14 contacts the bottom of the second fixing frame 13, and the other end contacts the top of the buffer plate 16. When one end of the connecting line 9 is stuck during rotation or when a large force is used to pull the connecting line 9, the other end of the connecting line 9 will be subjected to a large tensile force, causing the other end of the connecting line 9 to be tightened. At this time, the connecting line 9 will squeeze the surface of the buffer plate 16 and make the buffer plate 16 squeeze the first spring 14, thereby buffering the force on the surface of the connecting line 9, avoiding or reducing the breakage of the connecting line 9 after being tightened by a large force, and improving the service life of the connecting line 9.
[0021] When the pulley 8 is rotated or the connecting wire 9 is pulled, the clamping assembly 12 is driven to move, so that the clamping assembly drives one end of the bus cable to move and move from one end of the cable duct 1 to the other end, thereby passing the bus cable through the inside of the cable duct 1, and there is no need for personnel to manually lay the bus cable inside the cable duct 1, thereby avoiding the problem of personnel frequently moving the climbing ladder and climbing multiple times when laying the bus cable into the cable duct 1. The wiring is relatively time-saving and labor-saving, and the use is relatively convenient.
