DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, not all combinations of features described in the embodiments are necessarily required for the solution of the utility model.

[0026] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figure 1 、 2 As shown, to prevent friction between the cable 2 and the end of the cable drum 26 when the cable 2 is released, a small cable laying bracket is provided. This bracket is used to guide the cable 2 from the upright position. The bracket includes a support column 17 fixed relative to the hole 21 in the cable drum. A cable 2 guiding device is provided on the support column 17. The cable 2 guiding device includes a support guide member located above the end of the cable drum 26 for supporting and guiding the cable 2. The portion of the support guide member that supports and guides the cable 2 is located at a distance from the support column 17 that is greater than the radius of the end of the cable drum 26. The bottom of the support column 17 has a circular base 7 with a diameter smaller than the hole 21 in the cable 2. The circular base 7 can be slightly smaller than the hole 21 in the cable 2, so that the support column 17 is stably fixed relative to the center axis of the hole 21 in the cable 2. During use, a guide wheel 1 can be positioned directly above the support shaft to pull the cable 2 upward.

[0029] The support guide comprises a guide ring 3 provided on the support column 17 , the diameter of the guide ring 3 being larger than the diameter of the end of the cable drum 26 , and the guide ring 3 having a smooth surface for contacting the cable 2 , thereby reducing friction.

[0030] In this embodiment, the upper end of the support column 17 is rotatably sleeved with a sleeve 20, and the support column 17 is provided with a protrusion 4 to prevent the sleeve 20 from sliding downward. The guide ring 3 is coaxially connected to the sleeve 20 through the spoke rod 5, so that the guide ring 3 can rotate freely relative to the support column 17, reducing the friction between the cable 2 and the guide ring 3, and also making it easier for the guide ring 3 to be removed from the end of the support column 17.

[0031] Example 2

[0032] like Figure 3 、 4 As shown, different from the above embodiment, the support guide member of this embodiment also includes an annular guide rail 6, and the guide ring 3 is slidably mounted on the annular guide rail 6, so that the guide ring 3 can rotate freely, further reducing the relative friction with the cable 2.

[0033] Example 3

[0034] like Figure 5 、 6 As shown, unlike the above embodiment, the circular base is eliminated. Instead, the bottom of the support column 17 is provided with an expansion mechanism that can extend into the central hole 21 of the cable drum. The expansion mechanism can expand radially relative to the central hole 21. A crossbar 18 is provided at the upper end of the support column 17. One end of the crossbar 18 is rotatably connected to the support column 1. The other end of the crossbar 18 is provided with a wire hole 19. The distance between the wire hole 19 and the support column 17 is greater than the radius of the cable drum 26. A sleeve 20 is provided at the end of the crossbar 18, which is rotatably sleeved on the support column 17.

[0035] The expansion mechanism expands radially relative to the central hole 21 , thereby fixing the support column 17 radially relative to the central hole 21 , that is, radially fixed relative to the cable drum 26 , so that the support column is located at the central axis of the cable drum 26 .

[0036] When in use, the cable 2 passes through the wire hole 19 and then passes through the upper and lower guide wheels 3, so when pulling the cable 2 upwards, the cable 2 rotates away from the end edge of the cable reel 26 under the support of the wire hole 19, thereby avoiding friction between the two, and the cable 2 rotates around the cable reel 26. Because the wire hole 19 avoids friction between the cable 2 and the cable reel 26, even if the guide wheel 3 deviates from the center axis of the cable reel 26 by a certain distance, the cable 2 can still rotate smoothly around the cable reel 26, thereby releasing the cable.

[0037] The crossbar 18 is a telescopic crossbar 18 with adjustable length to adapt to cable reels 26 of different diameters. The telescopic crossbar 18 can have various forms of telescopic extension, as long as the length of the support can be adjusted, for example, the telescopic crossbar 18 can include a threaded tube connected to the sleeve 20, the threaded tube is fitted with a screw rod, the threaded tube is a tube body with a threaded inner cavity, the screw rod is threadedly connected to the threaded tube, the wire hole 19 is connected to the end of the screw rod, and the screw rod is rotated relative to the threaded tube to achieve telescopic extension of the screw rod relative to the threaded tube, that is, the length of the crossbar 18 is adjusted.

[0038] At least two crossbars 18 are symmetrically arranged on the support column 17, and the wire hole 19 on one of the crossbars is provided with a counterweight 22 to balance the stress on the support column 17. By removing the counterweight, the release of two cables 2 wound around the cable reel 26 can be achieved, that is, the two cables 2 pass through two different wire holes 19 respectively, thereby achieving simultaneous release of the two cables 2.

[0039] The expansion mechanism includes a deformation rod, the deformation rod includes two rod bodies 23 hingedly connected at the ends, a sliding sleeve 24 is sleeved on the support column 17, the two ends of the deformation rod are hingedly connected to the sliding sleeve 24 and the support column 17 below the sliding sleeve 24 respectively, and a pushing mechanism is arranged above the sliding sleeve 24 to push the sliding sleeve 24 downward relative to the support column 17.

[0040] The pushing mechanism is, for example, a sleeve 25 sleeved on the support column 17, the support column 17 is provided with external threads matched with the internal threads of the sleeve 25, the sleeve 25 rotates relative to the support column 17 to realize axial movement relative to the support column 17, thereby realizing pushing of the sliding sleeve 24, pushing of the sliding sleeve 24 can make the included angle between the two rod bodies 23 of the deformation rod smaller, thereby making the radial distance between the positions where the two rod bodies 23 are connected relative to the support column 17 larger, thereby making the end of the rod body 23 press against the side wall of the middle hole 21, making the rod body 23 be clamped relative to the middle hole 21, preventing the support column 17 from moving axially and radially relative to the cable reel 26, by making the rod body 23 abut at different positions in the middle hole 21, the height of the wire hole 19 relative to the cable reel 26 can be adjusted, the radial deformation of the deformation rod can be adapted to middle holes 21 of different diameters, and thus can be adapted to cable reels 26 of various models.
