Technical Field

[0001] The invention relates to the technical field of cable pay-off equipment, and in particular to a cable pay-off device to prevent cable from falling off. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cables and wires are generally composed of three parts: core wire, insulating sheath and protective sheath. Cables are usually made up of multiple wires bundled together, and the structure is relatively complex. Each core is insulated from each other, and an insulating protective layer is added on the outside. Cables have higher efficiency and stronger anti-interference ability when transmitting electric energy or signals. Cables often use cable reel rollers to reel in and unreel.

[0003] However, when some cable unwinding devices are used to wind up the cable, once there is no traction force, the cable will become loose and detach from the reel. Once the cable is loose, it is easy to cause the cable to be entangled during the subsequent winding or unwinding work, and it needs to be tightened manually. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-13A cable anti-separation pay-out device comprises a bottom plate 03, bearing rotating seats 02 are symmetrically arranged on the upper surface of the bottom plate 03, a cable winding roller 01 is rotatably arranged between the bearing rotating seats 02 on both sides, an anti-separation unit 04 is arranged on the upper surface of the bottom plate 03 below the bearing rotating seat 02, the anti-separation unit 04 comprises a mounting frame 2, a supporting mechanism 1 is symmetrically installed on the bottom end surface of the mounting frame 2, a wire pressing roller 3 is rotatably arranged on the upper part of the mounting frame 2, and the cable winding roller 01 is used for winding up the cable.

[0018] The supporting mechanism 1 includes a telescopic rod 14, the bottom of which is fixed on the upper surface of the base plate 03, and a connecting plate 11 is horizontally fixedly connected to the top surface of the movable telescopic rod body at the top of the telescopic rod 14, and the connecting plate 11 is installed at the bottom of the mounting frame 2. A fixed seat 12 is arranged on the outside of the telescopic rod 14, and the fixed seat 12 is arranged on the upper surface of the base plate 03. A through hole is opened in the middle of the upper surface of the fixed seat 12, and the movable telescopic rod body at the top of the telescopic rod 14 is located at this through hole, and a spring 13 is sleeved on the outside of the movable telescopic rod at the top of the telescopic rod 14, one end of the spring 13 is fixedly connected to the upper surface of the fixed seat 12, and the other end of the spring 13 away from the fixed seat 12 is fixedly connected to the bottom surface of the connecting plate 11, so that the spring 13 is convenient for releasing elastic potential energy to slowly move the telescopic rod 14 upward and eject it.

[0019] In addition, bolt holes 111 are symmetrically opened on the upper surface of the connecting plate 11 , and a fixing component 7 is screwed onto the bolt hole 111 . The bolt hole 111 is convenient for screwing the fixing component 7 into, so that the connecting plate 11 is installed at the bottom of the mounting frame 2 .

[0020] Among them, rotating seats 21 are arranged at the ends of both sides of the mounting frame 2, and a crimping roller 3 is rotatably arranged between the rotating seats 21 on both sides. Mounting plates 22 are symmetrically arranged on the upper surface of the mounting frame 2, and mounting holes 221 are symmetrically opened on the mounting plates 22. The fixing component 7 is installed at the mounting hole 221. A mounting groove 23 is opened at the bottom surface of the mounting frame 2 below the mounting plate 22. The connecting plate 11 is installed in the mounting groove 23, and the threaded hole 111 is aligned with the center of the mounting hole 221. The mounting hole 2 is used for the installation of the fixing component 7.

[0021] Moreover, the wire-crimping roller 3 includes a roller body 31, and the outer wall of the roller body 31 is covered with a silicone sleeve 32. The wire-crimping roller 3 can contact the cable on the cable winding roller 01. The ends of the roller body 31 are fixedly connected with rotating rods 33, and the rotating rods 33 are rotatably set on the fixed seat 12. When the wires and cables of the cable winding roller 01 are pulled out, the wire-crimping roller 3 can always press the cables and rotate with them, thereby achieving the effect of preventing them from detaching.

[0022] In addition, a pulling block 4 is fixedly connected to the middle part of the bottom surface of the mounting frame 2, a limiting mechanism 5 is arranged on the upper surface of the bottom plate 03 below the pulling block 4, a plug column 6 is arranged on one side of the limiting mechanism 5, a connecting rod 41 is arranged on the upper surface of the pulling block 4, the other end of the connecting rod 41 away from the pulling block 4 is fixedly connected to the middle part of the bottom surface of the mounting frame 2, a handle 42 is arranged on the side wall of one side of the pulling block 4, a limiting groove 43 is provided on the side wall of one side of the pulling block 4 below the handle 42, and the pulling block 4 is used to pull the mounting frame 2 downward as a whole.

[0023] Moreover, a limiting hole 61 is opened in the middle of the upper surface of the column 6, and a limiting plug rod 8 is inserted in the limiting hole 61. The limiting plug rod 8 includes a pinch block 81, and a plug rod 82 is vertically fixedly connected to the middle of the bottom surface of the pinch block 81. The plug rod 82 can be inserted into the limiting hole 61, and the plug rod 82 plays a role in limiting the rotation of the limiting plate 52.

[0024] In addition, the limiting mechanism 5 includes a rotating rod 51, on which a limiting plate 52 is rotatably arranged, and the limiting plate 52 can be rotated into the limiting groove 43. One end of the limiting plate 52 is rotatably arranged on the rotating rod 51, and a socket 522 is provided at the other end of the limiting plate 52 away from the rotating rod 51. The aperture of the socket 522 is consistent with the diameter of the plug rod 82, and the socket 522 can be aligned with the center of the limiting socket 61. A pull plate 521 is fixedly connected to the side wall of one side of the plate body of the limiting plate 52 and located on one side of the socket 522. A through hole is provided on the pull plate 521. After the limiting plate 52 is rotated into the limiting groove 43, the pulling block 4 can be stuck, so that the spring 13 remains in a compressed state.

[0025] In this embodiment, when the cable winding roller 01 with the cable wound on it is used for winding and unwinding work, after the cable is pulled out from the cable winding roller 01, the pulling block 4 that is stuck by the limiting mechanism 5 can be released. First, the limiting plug rod 8 is separated from the plug column 6, and the pinching block 81 is pinched so that the plug rod 82 can be separated from the limiting socket 61 and pulled out from the socket 522. Then, the through hole on the pulling plate 521 can be pulled so that the limiting plate 52 rotates on the rotating rod 51, and the limiting plate 52 is rotated out of the limiting groove 43, so that the limiting plate 52 does not get stuck on the pulling block 4.

[0026] When the pulling block 4 is no longer stuck by the limit plate 52, the spring 13 can release its elastic potential energy, and the spring 13 moves upward, thereby cooperating with the connecting plate 11 to move upward, and the telescopic rod 14 ensures that the connecting plate 11 always moves in a straight line, and the connecting plates 11 on both sides drive the upper mounting frame 2 to move upward, so that the wire pressing roller 3 above the mounting frame 2 can move upward, and the wire pressing roller 3 can press the cable on the cable winding roller 01.

[0027] When the crimping roller 3 is pressed on the cable, as the cable is pulled, the crimping roller 3 will rotate in coordination with its movement while pressing, and the silicone sleeve 32 can protect the pulled-out cable from being squeezed and damaged by the crimping roller 3, and after one layer of cable is pulled out and becomes the next layer, the spring 13 continues to release elastic potential energy to ensure that the crimping roller 3 is always pressed on the cable, even when the cable is not pulled out and there is no pulling force on the cable winding roller 01, the cable will not fall off because of the crimping roller 3, thereby preventing the cable from loosening.

[0028] Moreover, the mounting frame 2 can also be disassembled at any time, and it is only necessary to unscrew the fixing component 7 from the bolt hole 111 , separate it from the mounting hole 221 , and separate the connecting plate 11 from the mounting groove 23 .

[0029] When there is no need to use the wire pressing roller 3 to press the cable, it is only necessary to pull the handle 42, and then pull the pulling block 4 downward to lower the height of the mounting frame 2, shrink the telescopic rod 14, and then pull it to a height where the limit plate 52 can be rotated into the limit groove 43. After the limit plate 52 is rotated into the limit groove 43, the insert rod 82 of the limit insert rod 8 is passed through the insertion hole 522 and then enters the insert column 6, so that the limit plate 52 can be prevented from being easily rotated out of the limit groove 43.

[0030] In the present invention, a pair of supporting mechanisms 1 are arranged at the bottom of the cable winding roller 01, and the wire pressing roller 3 of the mounting frame 2 on the supporting mechanism 1 is cooperated so that the wire pressing roller 3 can always press on the cable. Even when the cable is not pulled out and there is no traction force for pulling out the cable on the cable winding roller 01, the cable will not fall off because of the wire pressing roller 3, thereby not causing the cable to loosen. The supporting mechanism 1 can ensure that the wire pressing roller 3 can always press on the cable as the cable is pulled out. In this way, the unwinding device has the function of preventing the cable from falling off from the cable winding roller 01 and causing the overall looseness of the cable.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
