Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the description herein is only intended to illustrate and explain embodiments of the present invention, and is not intended to limit embodiments of the present invention.

Fig. 1 is a side view of an adjustable pay-off device according to an embodiment of the present invention. Fig. 2 is a top view of an adjustable pay-off device according to an embodiment of the present invention. Fig. 4 is an enlarged view at a in fig. 1 of an adjustable pay-off according to an embodiment of the invention. The pay-off device may include: the device comprises an underframe 1, a bracket 2, a fixed frame 3, a bolt 7, a rotating rod 5, a connecting pipe 11, a connecting rod 6 and a supporting rod 4. A threaded hole 12 is also arranged in the middle of the fixing frame 3. The pay-off device may include two base frames 1, two brackets 2 may be provided on each base frame 1, and a fixing frame 3 may be provided on top of the two brackets 2 to connect the two brackets 2 together. After the fixing frame 3 connects the tops of the two brackets 2 together, the two brackets 2 and the base frame 1 can form a stable triangle so as to ensure that the main body of the pay-off device cannot deform. A threaded hole 12 may be formed in the middle of the fixing frame 3, and a bolt 7 may be disposed in the threaded hole 12, and the bolt 7 may move up and down along the thread pattern of the threaded hole 12. A rotating rod 5 may be provided at the bottom of the bolt 7, and the rotating rod 5 may rotate the bolt 7 so that the bolt 7 moves up and down in the threaded hole 12.

A connecting rod 6 may be provided on top of the bolt 7, and a connecting tube 11 may be provided on top of the connecting rod 6. The supporting rod 4 is used for supporting the pay-off reel, so that the pay-off reel can rotate along the supporting rod 4 to pull out the cable quickly. The support bar 4 may be coupled to the connection bar 6 at each end thereof by means of a connection pipe 11, so that the support bar 4 may be integrally formed with the two base frames 1 and the support bar 4 can be moved up and down by means of the rotation of the bolts 7. When the pay-off device works, the distance between the supporting rod 4 and the ground can be adjusted according to needs, and the support 2 and the bottom frame 1 form a stable triangle, so that the pay-off device can perform pay-off well.

In one embodiment of the present invention, as shown in fig. 2 and 3, the pay-off device may include a gear 8, a rotating rod 13, a rotating shaft 14, and a handle 15. The under frame 1 may be provided with a rack plate 9, a limit hole 17 and a limit groove 18 therein. A rack plate 9 may be provided at the middle of the base frame 1, and a limit hole 17 may be provided at one side of the base frame 1 and a limit groove 18 may be provided at the other side. The height of the stopper groove 18 and the stopper hole 17 may be at the same level. The rack plate 9 may be lower than the height of the stopper groove 18 and the stopper hole 17 by a distance. The rack plate 9 is identical in length to the limit groove 18 and the limit hole 17. The pay-off device may comprise a gear wheel 8, the gear wheel 8 may be arranged on a rack plate 9, and both end faces of the gear wheel 8 are rotatably connected with the bottom of the carrier 2, so that the gear wheel 8 can carry the carrier 2 to rotate back and forth along the rack plate 9. The rotating rod 13 can pass through the center of the gear 8 to drive the gear 8 to rotate, and one end of the rotating rod 13 is disposed in the limiting groove 18, and the other end passes through the limiting hole 17, so that the rotating rod 13 can move in the limiting hole 17 and the limiting groove 18. A handle 15 is provided at the other end of the rotating rod 13, and the handle is connected to the rotating rod 13 through a rotating shaft 14 and can rotate the rotating rod 13, so that when the distance between the two brackets 2 needs to be adjusted, a worker can rotate the rotating rod 13 through the handle 15 so that the electric gear 8 moves on the rack plate 9, rotate the gear 8 to a designated position, and thus adjust the distance between the two brackets 2. Since the handle 15 is connected to the rotary rod 13 through the rotary shaft 14, the handle 15 can be folded by rotating inward along the rotary shaft 14. After the worker adjusts the gear 8 to a designated position, the worker can fold the handle 15 inwards by rotating the handle, so that the handle 15 falls in the limiting hole 17 on the bottom frame 1, and then the handle 15 is limited by the limiting hole 17 and cannot move continuously, so that the gear 8 is limited to move, and the distance between the two brackets 2 is further limited.

In one embodiment of the present invention, as shown in fig. 4, the wire discharging device may include a fixed side plate 10. A pair of fixed side plates 10 are respectively arranged at both sides of the fixed frame 3, and the fixed side plates 10 can be rotatably connected with the top of the bracket 2. When the staff adjusted the distance between two supports 2, because mount 3 rotated through fixed

curb plate

10 and 2 between two and be connected, so this mount 3 can not influence the free rotation of two supports 2 to in the better distance between two supports 2 of adjusting.

In one embodiment of the present invention, as shown in fig. 3, one end of the rotating rod 13 is T-shaped, and one end of the T-shaped short side of the rotating rod 13 is disposed in the limiting groove. When the rotating rod 13 rotates, because one end of the rotating rod 13 is disposed in the limiting groove 18 and the other end passes through the limiting hole 17, the rotating rod 13 is limited by the limiting hole 17 and the limiting groove 18 to move in the vertical direction, so that the rotating rod 13 cannot be separated from the chassis 1.

In one embodiment of the present invention, as shown in fig. 5, the bottom of the connecting rod 6 is provided with a cavity. The top of the bolt 7 has a larger diameter than the body and the top of the bolt 7 may be located in a cavity in the bottom of the connecting rod 6. Because the top diameter of the bolt 7 is larger than its main body diameter, the displacement of the bolt 7 in the vertical direction of the connecting rod 6 is limited when the bolt 7 moves in the cavity of the connecting rod 6. When the distance between the supporting rod 4 and the ground needs to be adjusted, the top of the bolt 7 drives the connecting rod 6 to move upwards by rotating the bolt 7, so that the distance between the supporting rod 4 is adjusted. Because the top of bolt 7 is in the bottom cavity of connecting rod 6, then the rotation of bolt 7 can not drive the rotation of connecting rod 6, also can not drive bracing piece 4 and rotate on the horizontal direction to guarantee the stable displacement of bracing piece 4 in vertical direction.

In an embodiment of the present invention, as shown in fig. 5, the wire releasing device may further include a spring 16, and the spring 16 may be disposed in a cavity at the bottom of the connecting rod 6 and connected to the top of the bolt 7. The spring 16 can buffer the impact force between the connecting rod 6 and the bolt 7 when the reel is placed on the support rod 4 to avoid wear between the connecting rod 6 and the bolt 7.

Through the technical scheme, the embodiment of the utility model provides a pair of pay-off with adjustable is through setting up two supports respectively on every chassis, be provided with the mount at the top of two supports in order to be in the same place two leg joint, be equipped with the screw hole at the middle part of mount, the bolt can reciprocate in the screw hole to can drive the upper and lower displacement at the bracing piece at bolt top, thereby can adjust the distance between bracing piece and the ground so that the unwrapping wire dish can be better unwrapping wire according to the diameter size of unwrapping wire dish.
