Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a stand for supporting a cable winding drum.

"Prior Art" Conventionally, when a cable is pulled and unwound from a winding drum for indoor wiring cords or cables for installing business telephones or home telephones, the drum rolls on the floor. Therefore, if the side plate of the drum is fixed in contact with the floor and the cable is unwound by hand, the cable will twist and kink, and it is necessary to untwist the kink part, which can easily cause a disconnection accident. If a horizontal bar is inserted into the drum, the horizontal bar is fixed, and the cable is pulled, inertia is applied to the drum, causing the cable to be unnecessarily fed out, and the fixing of the horizontal bar requires input or a fairly large device. .

``Problems to be solved by the invention'' This invention supports the cable drum rotatably around the vertical pole, eliminates the risk of unnecessary feeding or kinking, and allows one person to handle and transport the cable while it is set on the drum, reducing labor and work. The object is to obtain a cable drum stand that can improve efficiency.

``Means to solve the problem'' This proposal supports a vertical column in the center of the machine base so that it can rotate around the center line, a cable drum receiving plate is installed at the base of the vertical column, and the cable drum is tightened at the upper end. A cable drum formed by removably screwing screws together, and having a plurality of recesses lined up along the outer periphery on the lower surface of the receiving plate, and a brake pin provided on the machine base to be press-fitted into the recesses with spring force. It consists of a stand for

``Operation'' Therefore, when the machine base is placed on the floor, the cable drum tightening screw at the upper end of the vertical column is removed, and the vertical column is inserted into the through hole in the center of the cable drum, the downward side plate of the drum becomes the receiving plate. The upper end of the supported upright pillar projects upward from the upper side plate. When the above-mentioned tightening screw is screwed into this protrusion and tightened, both side plates of the drum are fixed to the receiving plate and the screw in the sliding direction and rotation direction between the screw and the receiving plate, and rotate in the horizontal direction together with the vertical column. It will move. When the cable wound around this drum is pulled, the drum is forcibly rotated together with the upright pillar, and the cable is unwound without twisting.The forcible rotation of the drum is caused by the pressing force of the brake pin against the recess. When the brake is applied and the towing is stopped, the drum stops rotating due to inertia, and there is no need to unwind the cable.

Embodiment A machine base 1 is formed by providing three legs 8 facing in the radial direction and a bearing 10 inside a machine casing 9 provided at the center thereof. The bearing 10 supports the base of the upright column 2 so as to be rotatable around the center line, and the disk-shaped receiving plate 3 of the downward side plate 11' of the cable drum 11 is provided in the shape of a flange on the base. Recesses 5 are arranged at regular intervals along the outer periphery of the lower surface. The recess 5 may be a through hole as shown in the figure, or may be a recess formed by pressing. A spiral 12 is formed at the upper end of the vertical column 2, and a cable drum tightening screw 4 is screwed thereto in a detachable manner. As shown in FIG. 2, this screw 4 has an outer surface formed into an inverted truncated conical surface, and the conical surface fits into the central through hole 13 of the cable drum 11. Further, a small and short cylinder 14 is provided upright on the upper surface of the leg 8, and the cylinder 14
A brake pin 7 having a spring 6 built in and supported by the spring 6 is slidably fitted, and the upper end of the pin 7 is press-fitted into the recess 5 by the force of the spring 6. By forming a tapered surface on the upper end surface, the receiving plate 3 can be rotated to a braking state. In the figure, 15 indicates a cable, and 16 indicates a non-slip rubber provided on the outer periphery of the leg 8.

``Effects'' Since the present invention is constructed as described above, not only can the cable drum 11 be easily and rotatably supported on the vertical pole 2, but also the inertia of the drum 11 is braked when the cable is fed out, so that there is no unnecessary feeding and there is no kink. The feeding cable can be used safely and easily, and the stand can be handled and transported while being set on the drum 11, reducing labor and improving work efficiency.
