Disclosure of utility model

In order to solve the problems mentioned in the background art, the utility model provides a pay-off rack.

The utility model discloses the following technical scheme: the utility model provides a pay off rack, includes first base, second base, first gyro wheel, second gyro wheel and screw rod, be equipped with the recess in first base and the second base, recess upper end opening, first gyro wheel and second gyro wheel rotatable mounting are in the recess, first base and second base up end are higher than first gyro wheel, the mounting height of first gyro wheel is less than the second gyro wheel, first base and second base one side is equipped with the inclined plane, first base and second base both sides are equipped with the arch, be equipped with the through-hole in the middle of the arch of first base, be equipped with the screw hole that runs through in the middle of the arch of second base, the screw rod passes the through-hole on the arch of first base both sides and the screw hole on the arch of second base both sides and is connected, the screw rod is hexagon head screw rod, be equipped with the step on the screw rod, step and through-hole terminal surface laminating.

Further, an extension line of the inclined plane is tangent to the outer circle of the first roller.

Further, the protrusions are arranged at the middle positions of the two sides of the first base and the second base.

Further, the screw rod is in clearance fit with the through hole on the first base.

The beneficial effects are that: compared with the prior art, the pay-off rack is a split pay-off rack, the bases on two sides are tensioned and close through the screw rod, so that the cable drum is supported close to the roller, cables on the cable drum are conveniently pulled out, the cable drum does not need to be rolled onto the roller by labor, the size is small, the structure is simple, the operation is convenient, and the labor is saved.

FIG. 2 is a schematic view in partial cross-section of the present utility model;

FIG. 3 is a schematic diagram illustrating the cooperation between a pay-off rack and a cable drum according to the present utility model;

in the figure: the cable drum comprises a first base, an 11-inclined plane, a 12-bulge, a 2-second base, a 3-first roller, a 4-second roller, a 5-screw and a 6-cable drum.

Detailed Description

As shown in fig. 1 to 3, a pay-off rack comprises a first base 1, a second base 2, a first roller 3, a second roller 4 and a screw 5, wherein a groove is formed in the first base 1 and the second base 2, the upper end of the groove is opened, the first roller 3 and the second roller 4 are rotatably installed in the groove, the upper end faces of the first base 1 and the second base 2 are higher than the first roller 3, the installation height of the first roller 3 is lower than that of the second roller 4, one side of the first base 1 and one side of the second base 2 are provided with inclined planes 11, a cable drum slides upwards more smoothly, protrusions 12 are arranged on two sides of the first base 1, a through hole is formed in the middle of each protrusion 12 of the first base 1, a threaded hole penetrating through is formed in the middle of each protrusion 12 of the second base 2, the screw 5 penetrates through the through holes in the protrusions 12 on two sides of the first base 1 and the threaded holes in the protrusions 12 on two sides of the second base 2, the screw 5 is a hexagon head screw 5, the screw 5 is conveniently screwed on the step 5, and the step 5 is conveniently screwed on the screw 5, and the step 5 is more smoothly screwed with the first base 2 and the screw 2.

The extension line of the inclined plane 11 is tangent to the outer circle of the first roller 3, and the cable drum 6 slides onto the first roller 3 through the inclined plane 11 more smoothly; the bulges 12 are arranged in the middle positions of the two sides of the first base 1 and the second base 2, so that the screw 5 is uniformly stressed, and the cable drum is supported more easily; the screw 5 is in clearance fit with the through hole in the first base 1, so that the screw 5 is convenient to install and take out.

When the pay-off device is used, the inclined planes 11 of the first base 1 and the second base 2 are opposite, the two ends of the cable drum 6 are placed respectively, the inclined planes 11 of the first base 1 and the second base 2 are in contact with the cable drum 6, the screw 5 is matched with threaded holes of the protrusions 12 on two sides of the second base 2 after passing through the through holes on the protrusions 12 on two sides of the first base 1, the screws 5 on two sides are rotated, the first base 1 and the second base 2 are close, the cable drum 6 approaches the first roller 3 through the inclined planes 11 until leaving the bottom surface and is supported by the first roller 3, at the moment, the cable drum 6 is also in contact with the second roller 4, the cable drum 6 rotates on the first roller 3 during pay-off, and the upper end faces of the first base 1 and the second base 2 are higher than the first roller 3 because the second roller 4 is not separated from the rollers during rotation, so that the pay-off smoothness is ensured, and meanwhile, the construction safety is ensured.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
