Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0046] The following describes the first embodiment in detail:

[0047] like Figure 1 and Figure 2As shown, the pay-off frame includes a base frame 1, on which an abutment wheel 2 is rotatably provided to support the cable reel placed on the base frame 1, and can support the cable reel to rotate. Specifically, the base frame 1 is a rectangular frame, and a symmetrical rectangular groove 11 is provided on the base frame 1. The abutment wheel 2 is rotatably provided in the rectangular groove 11, and the number of the abutment wheels 2 can be set to multiple. In this embodiment, the dimensions of the two ends of the abutment wheel 2 are larger than the middle dimension, so that the disk surface on both sides of the cable reel can be restricted to the middle of the abutment wheel 2 to maintain stability. In this embodiment, the ends of the base frame 1 on both sides of the rectangular groove 11 are provided with inclined ramps 12, so that the cable reel can roll along the inclined ramps 12 to the base frame 1, thereby facilitating the movement of the cable reel.

[0048] Vertical plates 3 are provided on opposite sides of the base frame 1. The two vertical plates 3 are symmetrically arranged about the center of the base frame 1. In this embodiment, the vertical plates 3 are provided on one side of the rectangular groove 11, and the rectangular groove 11 is located between the two vertical plates 3. Furthermore, in order to ensure the strength of the vertical plates 3, each vertical plate 3 is provided with a reinforcing rib 32. In addition, the vertical plates 3 are provided with a long groove 31 extending in the vertical direction. Each long groove 31 is detachably connected to a positioning member 6. The positioning member 6 protrudes from the vertical plate 3 so that the two positioning members 6 are jointly inserted into the center holes on both sides of the cable reel. The positioning member 6 is locked to the vertical plate 3 by a locking assembly connecting the positioning member 6 and the vertical plate 3. In this embodiment, by combining the positioning member 6 with the abutment wheel 2, part or all of the weight of the cable reel is distributed to the abutment wheel 2, reducing the stress on the positioning member 6 and extending its service life. The positioning member 6 can also prevent the cable reel from detaching from the abutment wheel 2 during the line unwinding process. In addition, the positioning member 6 can move along the long slot 31 to adjust the height on the vertical plate 3, so as to adapt to cable reels of different sizes and expand the adaptability range.

[0049] Specifically, the locking assembly includes a connecting member 4 and a locking member 5; wherein the connecting member 4 includes an inserting tube 41 and a clamping disk 42 provided at the first end of the inserting tube 41, the clamping disk 42 being provided with a first through hole coaxial with the inserting tube 41, and the positioning member 6 being fixedly inserted into the inserting tube 41 through the first through hole; the locking member 5 includes a locking tube 51, one end of which is provided with a locking disk 52, the locking disk 52 being provided with a second through hole coaxial with the locking tube 51, the locking tube 51 being sleeved on the outside of the inserting tube 41 and capable of being fastened to the inserting tube 41 so that the clamping disk 42 and the locking disk 52 can jointly clamp or loosen the vertical plate 3. The above structure makes it easier to fix the positioning member 6. Furthermore, the side of the clamping disk 42 and the locking disk 52 facing the vertical plate 3 is provided with an anti-slip pad to increase friction and make the clamping more stable.

[0050] More specifically, a first thread is provided on the outside of the insertion tube 41, and a second thread is provided inside the locking tube 51 that is threadedly connected to the first thread. This allows the locking tube 51 to be screwed and fixed to the insertion tube 41, and the threaded connection is more convenient. Furthermore, to facilitate screwing, a plurality of shifting blocks 53 are provided on the side of the locking disk 52 facing away from the locking tube 51. The shifting blocks 53 are distributed around the circumference, thereby facilitating the application of force during screwing. In this embodiment, the shifting blocks 53 and the locking disk 52 are integrally formed for ease of manufacturing.

[0051] In this embodiment, a fixing ring 43 is provided at the second end of the plug-in barrel 41. A plurality of insertion holes 44 are distributed circumferentially on the outer wall of the fixing ring 43. An annular groove 61 is formed on the surface of the positioning member 6. The insertion holes 44 face the annular groove 61 and are secured thereto by means of a plug-in connector 7. This prevents the positioning member 6 from rotating with the cable reel and interfering with the pay-off operation. Thus, the positioning member 6 is fixed to the plug-in barrel 41 by means of plugging, which simplifies the securing of the positioning member 6.

[0052] Furthermore, to ensure stable insertion, an elastic ring 72 surrounds the outer side of the fixing ring 43. A pull ring 71 is provided on the end of the connector 7 away from the annular groove 61. Multiple connectors 7 are enclosed in the elastic ring 72 via the pull ring 71. Thus, the elastic ring 72 restrains the connectors 7 within the insertion hole 44, while the pull ring 71 holds the elastic members in place. In this embodiment, the elastic ring 72 is a rubber ring.

[0053] Furthermore, in order to facilitate the application of force to the positioning member 6 and facilitate installation, a positioning handle 62 is provided at one end of the positioning member 6 away from the cable reel; illustratively, the positioning handle 62 is a ring handle for easy operation.

[0054] Example 2:

[0055] like Figure 1 and Figure 3 As shown, two receiving grooves 13 are symmetrically provided at both ends of the chassis 1, and rotating support wheels 14 are provided in the receiving grooves 13, so that the pay-off frame can be moved by the support wheels 14 to adjust the position of the pay-off. In order to ensure that the pay-off frame as a whole does not roll through the support wheels 14 when the pay-off is paid out, based on this, a driving assembly 8 is also provided on the chassis 1, and the driving assembly 8 is connected to the support wheels 14 to be able to drive the support wheels 14 to protrude from the receiving grooves 13 when the pay-off needs to be moved, so as to facilitate movement or be stored in the receiving grooves 13 when the pay-off is in progress, so as to prevent the chassis 1 from being easily pulled and moved during the pay-off process, so as to achieve a better pay-off effect.

[0056] Specifically, a movable connecting plate 15 is disposed between the receiving slots 13 on the same side. The connecting plate 15 is positioned at the output end of the drive assembly 8 and is equipped with two symmetrical connecting blocks 16, each of which is provided with a vertical slot 17. The sidewalls of the receiving slots 13 are provided with inclined guide slots 18. In this embodiment, the guide slots 18 extend obliquely from the bottom end of the base frame 1 to the top end. The central axis of the support wheel 14 is movably inserted into the guide slots 18, with the end of the central axis of the support wheel 14 near the vertical slot 17 extending into the vertical slot 17. In this embodiment, the central axis of the support wheel 14 can be a pin. With this structure, the drive assembly 8 drives the connecting plate 15 to repeatedly move, thereby driving the connecting blocks 16. This, in turn, propels the support wheel 14 axially along the guide slots 18 and the vertical slot 17, between the bottom and top ends of the base frame 1, thereby enabling the support wheel 14 to protrude from or be retracted into the receiving slot 13.

[0057] In this embodiment, the drive assembly 8 includes a threaded rod 81. A threaded barrel 82 is provided on the connecting plate 15. The threaded rod 81 is screwed into the threaded barrel 82. A screw hole is provided on the base frame 1. One end of the threaded rod 81 is screwed into the screw hole, thereby rotating the threaded rod 81 to move the connecting plate 15 along the threaded rod 81. To facilitate rotation of the threaded rod 81, a screw handle 83 is provided on the end of the threaded rod 81 away from the base frame 1. The use of this screw drive makes adjustment more precise. It is understood that in other embodiments, the drive assembly 8 can also adopt a cylinder drive or other drive method.

[0058] Furthermore, in order to increase the friction of the chassis 1 and prevent the chassis 1 from moving when the line is released, a plurality of anti-skid rubber pads are provided on the lower part of the chassis 1 to achieve an anti-skid effect.

[0059] Furthermore, in order to facilitate movement, the chassis 1 is also provided with a push handle 9, so that the entire body is exerted with force by pushing the handle 9. Furthermore, in order to facilitate storage of the push handle 9, a storage groove 19 is provided on the chassis 1, and the push handle 9 is hinged to the chassis 1 so that the push handle 9 can be placed in the storage groove 19.

[0060] The other structures are the same as those in the first embodiment and will not be described in detail here.

[0061] This embodiment further provides a method for using a pay-off stand, which comprises the following steps:

[0062] S1. Turn the push handle 9 out of the receiving groove 19, and then place the cable reel on the base frame 1 so that the cable reel abuts against the abutment wheel 2;

[0063] S2, loosening the connection between the locking cylinder 51 and the plug-in cylinder 41, so that the plug-in cylinder 41 moves up and down along the long slot 31;

[0064] S3. Align the plug-in tube 41 with the center hole of the cable reel, screw and fix the locking tube 51 and the plug-in tube 41, insert the positioning piece 6 into the plug-in tube 41, and fix the positioning piece 6 to the plug-in tube 41 through the plug-in piece 7. Clamp the vertical plate 3 together with the clamping disc 42 and the locking disc 52 to fix the positioning piece 6 on the vertical plate 3; at this time, most or all of the force of the cable reel can be borne by the abutting wheel 2, and the positioning piece 6 mainly plays the role of limiting the cable reel, reducing the force on the positioning piece 6 and extending its service life;

[0065] S4. Drive the connecting plate 15 to move by the driving assembly 8, adjust the supporting wheel 14 so that the supporting wheel 14 protrudes from the receiving groove 13 and can contact the ground to support the base frame 1. Push the handle 9 to move the base frame 1 so that the cable reel is placed in a suitable position for laying out the cable. After the movement is completed, drive the connecting plate 15 to move by the driving assembly 8, adjust the supporting wheel 14 so that the supporting wheel 14 is stored in the receiving groove 13, and place the base frame 1 on the ground.

[0066] S5. Pull the cable on the cable reel to rotate the cable reel on the abutment wheel 2 to pay out the cable.

[0067] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
