The utility model discloses can solve the winding problem of various size electric wire reels unwrapping wire in-process, the succinct compactness of structure, simple operation and unwrapping wire are efficient.

Description

Paying-off device

Technical Field

The utility model relates to a unwrapping wire ware especially relates to a unwrapping wire ware of wireless dish wire.

Background

The pay-off device is also called a winder and a reel, and generally comprises a rotating shaft and wire coils arranged on two sides of the rotating shaft, wherein an electric wire is wound on the pay-off device, the coil can be a single-core electric wire, and also can be a telephone wire, a network wire or a television line, and the pay-off of the pay-off device can be realized by pulling the wire on the coil to rotate the rotating shaft. At present, in the process of wire purchase, a paying-off reel is cancelled by a merchant for reducing cost, and the problem of wire winding is easily caused in the process of paying off. Because the model, the thickness of coil are different, and the coil reserves hollow size also different, lead to coil and unwrapping wire ware cooperation discordance to the electric wire is crooked winding easily when making the acting as go-between, and it is inconvenient to use.

Disclosure of Invention

A paying-off device comprises a tension spring, a support rod cap, a shaft disc, a fixing support, support rods, a locking nut and a fixing disc, wherein 3 square holes used for installing the support rods are formed in the shaft disc at intervals of 120 degrees, the support rods are connected with the support rod cap, one end of the tension spring is sleeved with a boss on the shaft disc, the other end of the tension spring is connected with a limiting hole of the support rods, the fixing disc is installed on a shaft of the shaft disc and can radially move along the shaft under the action of the tension spring to compress an electric wire, and the locking nut is installed on the shaft of the shaft disc and used for locking the fixing disc; the shaft of the fixed bracket passes through the shaft disc and plays a supporting role for the shaft disc.

Furthermore, the position of the supporting rod can change along with the diameter of the wire coil hole and is always in a tensioning state under the action of the tension spring.

Furthermore, the fixed disc is of a detachable split structure.

Further, the fixed disc (7) is locked by a locking nut (6).

The beneficial effects of the embodiment of the invention are as follows: the winding problem of various sizes wire reel unwrapping wire in-process can be solved, and the structure is succinct compact, and the simple operation and unwrapping wire are efficient.

Detailed Description

Referring to fig. 1 and 2, an embodiment of the present invention provides a paying-off device, where the paying-off device includes a tension spring 1, a support rod cap 2, a reel 3, a fixing bracket 4, a support rod 5, a locking nut 6 and a

fixing disk

7, 3 square holes with an angle of 120 ° are arranged on the reel 3 for installing the support rod 5, the support rod 5 is connected to the support rod cap 2, one end of the tension spring 1 is connected to a boss on the reel 3, the other end of the tension spring is connected to the support rod 5 and a preset limiting hole 8 on the support rod cap 2, the fixing disk 7 is installed on a shaft of the reel 3 and can axially move along the shaft to clamp a wire, and the locking nut 6 is installed on the shaft of the reel 3 to fix the fixing disk 7; the shaft of the fixed bracket 4 passes through the shaft disc 3 and supports the shaft disc 3. The position of the support rod 5 can change along with the diameter of the wire coil hole and is always in a tensioning state under the action of the tension spring 1. The fixed disc 7 is of a detachable split structure. The fixed disc 7 is locked by the locking nut 6 and can adapt to the compaction of wire bundles with different sizes.

When in use, the wire coil of the pay-off device is taken down from the bracket 4; the locking nut 6 is taken down by rotation to axially move the fixed disk 8 away from the disk shaft; the tension spring 1 connected to one end of the shaft disc is taken down. The support rod 5 and the support rod cap 2 mounted on the hub are moved until near the center.

Mounting a wire coil needing to be paid off on a shaft disc, and enabling the support rod 5 to penetrate through a central hole of the wire coil; moving the support rod 5 and the support rod cap 2 to the edge of the central hole of the wire coil; connecting a tension spring 1 to the boss position of the shaft disc; the fixing disc 7 is tightly pressed on the wire coil, and the locking nut 6 is screwed to tightly press the wire harness through the fixing disc 8.

The free paying-off can be completed by installing and hanging the paying-off device on the fixed bracket 4.

To sum up, the utility model provides a winding problem of various size electric wire reels unwrapping wire in-process, and the succinct compactness of unwrapping wire ware structure, simple operation and unwrapping wire are efficient.
