[0019] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0020] Embodiment 1

[0021] This embodiment provides a rotary pressing device for a cable reel, as Figure 1 and 2 shown, including a fixed base 1 and a rotary column 2, a rotating mechanism and a pressing mechanism provided above the fixed base 1.

[0022] The rotating mechanism is rotatably connected to the fixed base 1 and is used to drive the cable reel to rotate. The rotary column 2 is connected above the rotating mechanism.

[0023] The pressing mechanism is arranged at the top of the rotary column 2. The pressing mechanism includes a pressing rod 4, a rotary handle 5 and a rotary pressing member 6. The rotary handle 5 is fixedly connected to the rotary pressing member 6, and the rotary pressing member 6 is in transmission connection with the pressing rod 4. The rotary handle 5 drives the pressing rod 4 to apply pressure to the cable reel through the rotary pressing member 6.

[0024] Working principle:

[0025] As Figure 3 shown, the cable reel is assembled above the fixed base 1 through the rotary column 2 and is located on the rotating mechanism. Before the worker pulls the cable, the pressing rod 4 is driven downward by the rotary handle 5 to tightly press the cable reel, so that the cable reel will not shift in position during the cable pulling process. During the process of the worker pulling the cable, the cable reel rotates and the worker only needs to stand still and pull.

[0026] Embodiment 2

[0027] Based on Embodiment 1, this embodiment provides a specific implementation manner of the rotating mechanism and the pressing mechanism.

[0028] As Figure 1 and 2 shown, the rotating mechanism includes a rotating bottom plate 3 and a slewing support 7. The rotary column 2 is fixedly connected above the rotating bottom plate 3. A threaded hole is provided at the center of the fixed base 1, and the rotating bottom plate 3 is rotatably connected to the fixed base 1 through the slewing support 7 and the threaded hole.

[0029] Furthermore, anti-slip strips for preventing the cable reel from sliding are provided on the top of the rotating bottom plate 3. In this embodiment, the anti-slip strips are V-shaped anti-slip strips.

[0030] In this embodiment, the rotary pressing member 6 is a rotary pressing nut.

[0031] Furthermore, a circular groove is provided inside the rotary handle 5, and the rotary pressing nut is installed in the circular groove. The rotary handle 5 and the rotary pressing nut are jointly arranged at the upper end of the rotary column 2 and their relative positions with respect to the rotary column 2 remain unchanged. In this embodiment, the rotary handle 5 and the rotary pressing nut only rotate relative to the rotary column 2, and the rotary handle 5 and the rotary pressing nut are always located at the top of the rotary column 2.

[0032] In this embodiment, the pressing rod 4 includes a cross bar and a vertical bar, and the lower end of the vertical bar is fixedly connected to the cross bar.

[0033] Furthermore, a U-shaped groove is provided at the top of the rotary column 2. The lower end of the vertical rod extends into the U-shaped groove, and the cross rod extends out of the rotary column 2 through the openings on both sides of the U-shaped groove.

[0034] Furthermore, in this embodiment, there are longitudinal threads on the outer peripheral side of the vertical rod. The vertical rod is sleeved in the rotary compression nut and is in threaded cooperation with the rotary compression nut. By rotating the rotary handle 5, the rotary handle 5 drives the vertical rod to move up and down in the U-shaped groove through the rotary compression nut, converting the rotational motion into a linear motion to further push the pressure rod 4 to press the cable reel to a proper position.

[0035] In this embodiment, the rotary handle 5 adopts a symmetric split structure. The rotary handle 5 is composed of a hand-held rod and a clamping block. The clamping block is internally provided with a concentric circular groove for installing and axially fixing the rotary compression nut. There is a threaded hole in the upper part of the clamping block to radially lock the rotary compression nut. The rotary handle 5, the rotary compression nut and the pressure rod 4 form a self-locking structure, which is convenient for assembly and simple in operation, and at the same time ensures the structural stability.
