Cable winding drum with adjustable inner diameter

Abstract

The present application relates to the technical field of cable winding drums, and discloses a cable winding drum with adjustable inner diameter, comprising two groups of drum bodies, each of which is rotatably mounted with a rotating rod, each of which is movably mounted with a moving block, each of which is hingedly mounted with four groups of driving plates, each of which is hingedly mounted with a sliding block at the bottom of each of which is hingedly mounted with an arc-shaped gasket. The present application drives another group of rotating rods to rotate by rotating the rotating rod, and then drives two groups of thread grooves to rotate by cooperating with the action of a cross groove and a cross rod. Since the thread directions of the two groups of thread grooves are opposite, the moving block can be driven to move in opposite directions. The moving block drives the sliding block to move through the driving rod, and then drives the arc-shaped gasket to move. Therefore, the inner diameter of the winding drum can be adjusted, thereby improving the adjustment range.

[0002] A cable reel (also called a cable bearing reel, cable drum, cable wheel, etc.) is a device used to store, transport and use cables. It usually consists of a central axis and two reels with edges to hold the cable so that it can be easily rolled, unwound or transported.

[0003] In the Chinese patent application number 202321170524.6, a cable winding reel with adjustable inner diameter is disclosed. By combining an adjustment component and a receiving part, the inner diameter of the winding reel can be adjusted to adapt to the production needs of different types of cables and improve the cable production efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that, in actual use of the above-mentioned device, when winding the cable, the width that can be wound is the spacing between the two discs, and the spacing between the two sets of disc bodies of the above-mentioned device is fixed, resulting in a smaller range of use, and when adjusting the inner diameter, the inner diameter can only be adjusted according to the position of the threaded hole, and the adjustment range is small.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to solve the problem that the interval between the two groups of disc bodies of the above device is fixed, resulting in a small range of use, the present application provides a cable winding disc with an adjustable inner diameter.

[0007] The present application provides a cable winding drum with adjustable inner diameter, which adopts the following technical solution:

[0008] A cable winding drum with adjustable inner diameter comprises two groups of drum bodies, each of which is rotatably mounted with a rotating rod, each of which is movably mounted with a moving block, each of which is hingedly mounted with four groups of driving plates, each of which is hingedly mounted with a sliding block at the bottom, and each of which is fixedly mounted with an arc-shaped gasket.

[0009] Preferably, the rotating rods are respectively provided with thread grooves with the same parameters but opposite directions, and the moving block cooperates with the thread grooves.

[0010] Preferably, four groups of slide grooves are evenly arranged on the disk body, and pulleys cooperating with the slide grooves are movably mounted on the bottom of the sliding block.

[0011] Preferably, the rotating rods are all provided with a cross slot, the rotating rods are movably connected via a cross rod, and both ends of the cross rod are fixedly mounted with a limit plate that matches the cross slot.

[0012] Preferably, the arc-shaped gaskets are each provided with a slot, the arc-shaped gaskets are connected by a connecting plate, support plates matching the slots are fixedly installed at both ends of the connecting plate, threaded holes are each provided on the arc-shaped gasket and the connecting plate, and the arc-shaped gasket and the connecting plate are connected by a threaded pin.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By rotating the rotating rod, the rotating rod cooperates with the cross groove and the cross rod to drive another set of rotating rods to rotate, and then drives the two sets of thread grooves to rotate. Since the thread directions of the two sets of thread grooves are opposite, the moving block can be driven to move in the opposite direction. The moving block drives the slider to move through the driving rod, and then drives the arc-shaped gasket to move, thereby adjusting the inner diameter of the winding drum, thereby increasing the adjustment range;

[0015] 2. By unscrewing the threaded pin from the arc-shaped gasket and then pulling the two sets of disc bodies, the disc bodies can drive the rotating rod and the arc-shaped gasket to move on the cross rod and the connecting plate respectively, so that the distance between the two sets of disc bodies can be adjusted. When the distance is adjusted to a suitable distance, the arc-shaped gasket and the connecting plate are fixed by the threaded pin, thereby improving the application range of the disc body.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a cable winding drum with adjustable inner diameter. Figure 1-4 , a cable winding drum with adjustable inner diameter, comprising two groups of drum bodies 1, each of which is rotatably mounted with a rotating rod 2, each of which is movably mounted with a moving block 3, each of which is hingedly mounted with four groups of driving plates 4, each of which is hingedly mounted with a slider 5 at the bottom of the driving plate 4, each of which is fixedly mounted with an arc-shaped gasket 6, each of which is respectively provided with a thread groove 7 with the same parameters but opposite directions on the rotating rod 2, and the moving block 3 cooperates with the thread groove 7, and four groups of sliding grooves 8 are evenly opened on the drum body 1, and each of which is movably mounted with a pulley 9 cooperating with the sliding groove 8 at the bottom of the slider 5;

[0023] By adopting the above technical solution, the rotating rod 2 is rotated, and the rotating rod 2 cooperates with the cross groove 10 and the cross rod 11 to drive the other group of rotating rods 2 to rotate, and then drives the two groups of thread grooves 7 to rotate. Since the thread directions of the two groups of thread grooves 7 are opposite, and the moving block 3 is restricted by the driving plate 4 and the slider 5, the rotating rod 2 can drive the moving block 3 to move in the opposite direction. The moving block 3 drives the slider 5 to move through the driving rod, and then drives the arc gasket 6 to move, thereby adjusting the inner diameter of the winding drum and improving the adjustment range.

[0024] Reference Figure 2-4 , a cross slot 10 is provided on each rotating rod 2, the rotating rods 2 are movably connected by a cross rod 11, and both ends of the cross rod 11 are fixedly installed with a limit plate 12 that matches the cross slot 10, a slot 13 is provided on each arc-shaped gasket 6, the arc-shaped gaskets 6 are connected by a connecting plate 14, and support plates 15 that match the slot 13 are fixedly installed at both ends of the connecting plate 14, threaded holes 16 are provided on the arc-shaped gasket 6 and the connecting plate 14, and the arc-shaped gasket 6 and the connecting plate 14 are connected by a threaded pin 17;

[0025] By adopting the above technical solution, the threaded pin 17 is screwed out from the arc-shaped gasket 6, and then the two groups of disk bodies 1 are pulled. The disk body 1 can drive the rotating rod 2 and the arc-shaped gasket 6 to move on the cross rod 11 and the connecting plate 14 respectively, so that the distance between the two groups of disk bodies 1 can be adjusted. When the distance is adjusted to a suitable distance, the arc-shaped gasket 6 and the connecting plate 14 are fixed by the threaded pin 17, thereby improving the application range of the disk body 1.

[0026] The implementation principle of a cable winding drum with adjustable inner diameter in the embodiment of the present application is as follows: rotate the rotating rod 2, and the rotating rod 2 cooperates with the cross groove 10 and the cross rod 11 to drive the other group of rotating rods 2 to rotate, thereby driving the two groups of thread grooves 7 to rotate. Since the thread directions of the two groups of thread grooves 7 are opposite, and the moving block 3 is restricted by the driving plate 4 and the slider 5, the rotating rod 2 can drive the moving block 3 to move in the opposite direction. The moving block 3 drives the slider 5 to move through the driving rod, and then drives the arc gasket 6 to move, thereby the inner diameter of the winding drum can be adjusted, and the adjustment range is increased. The threaded pin 17 is unscrewed from the arc gasket 6, and then the two groups of disk bodies 1 are pulled. The disk body 1 can drive the rotating rod 2 and the arc gasket 6 to move on the cross rod 11 and the connecting plate 14 respectively, so that the distance between the two groups of disk bodies 1 can be adjusted. When the distance is adjusted to a suitable distance, the arc gasket 6 and the connecting plate 14 are fixed by the threaded pin 17, thereby increasing the application range of the disk body 1.
