[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 3 As shown, the utility model provides a communication cable taking-up and releasing device, comprising: a movable trolley 1, a cable roller 2 is provided above the trolley 1, an arc groove 9 is formed on the top of the trolley 1 to cooperate with the bottom of the cable roller 2, a plurality of rotating parts for rotation are provided at equal distances along the edge of the arc groove 9, and a rotating area for rotation of the cable roller 2 is formed between the tops of the plurality of rotating parts.

[0025] Combination Figure 3-4 As shown, the rotating member includes rollers 10 , and a plurality of rollers 10 are rotatably installed in the arc groove 9 .

[0026] As mentioned above, when using the trolley 1, cable roller 2 and multiple rotating parts provided by the utility model, the multiple rotating parts are rotatably installed on the trolley 1 through the arc groove 9, and the cable roller 2 is placed above the multiple rollers 10. When the cable is pulled, the cable roller 2 is driven to rotate on the multiple rollers 10, so as to facilitate the automatic release of the cable. When the cable roller 2 is pushed, the cable roller 2 can rotate on the multiple rollers 10, so as to facilitate the winding of the cable on the cable roller 2.

[0027] In the present utility model, combined with Figure 3 As shown, the outside of the trolley 1 of this embodiment is also provided with a latch rod 11 for limiting the position of the cable roller 2, and an annular groove 3 is opened on the outer wall of the cable roller 2, and one end of the latch rod 11 is at least partially inserted into the annular groove 3.

[0028] Combination Figure 1-2 and Figure 4-5 As shown, a hollow mounting seat 4 is also provided on the outside of the trolley 1, and a first spring 12 and a blocking piece 13 are provided in the mounting seat 4 from the outside to the inside. The latch rod 11 movably passes through the mounting seat 4, the blocking piece 13 is welded on the latch rod 11, the first spring 12 is sleeved on the latch rod 11, and a paddle 5 connected to the end of the latch rod 11 is provided on the outside of the mounting seat 4.

[0029] As mentioned above, when using the latch rod 11 provided by the utility model, the latch rod 11 is movably connected to the trolley 1 through the mounting seat 4. When the cable roller 2 is in the arc groove 9, the latch rod 11 is automatically inserted into the annular groove 3 by the elastic force of the first spring 12, so that the cable roller 2 is prevented from being separated from the arc groove 9 by the latch rod 11. At the same time, through the cooperation between the annular groove 3 and the latch rod 11, the latch rod 11 is prevented from interfering with the cable roller 2 when it rotates. The position of the latch rod 11 can be adjusted by the paddle 5, so that the latch rod 11 can be easily separated from the annular groove 3, thereby facilitating the cable roller 2 to be removed from the arc groove 9.

[0030] In the present utility model, combined with Figure 1-2 and Figure 4 As shown, movable plates 8 that are rotatably mounted on both sides of the trolley 1 of this embodiment are in contact with the ground, and a retractable telescopic member is provided between the bottom of each movable plate 8 and the trolley 1 .

[0031] Combination Figure 6 As shown, the telescopic member includes a first telescopic rod 6 and a second telescopic rod 7, and the ends of the first telescopic rod 6 and the second telescopic rod 7 that are separated from each other are rotatably mounted on the trolley 1 and the movable plate 8 respectively. A mounting hole 15 is opened at one end of the second telescopic rod 7, and a second spring 14 extending to the first telescopic rod 6 is arranged in the mounting hole 15.

[0032] As mentioned above, when using the movable plate 8 provided by the utility model, when manual loading is required, one end of the movable plate 8 is allowed to contact the ground, at which time the first telescopic rod 6 and the second telescopic rod 7 are extended and retracted, and the cable roller 2 is rolled, so that the cable roller 2 is allowed to roll directly to the top of the trolley 1 through the movable plate 8, and the cable roller 2 enters the arc groove 9 under inertia. At this time, the movable plate 8 is released, and the second spring 14 between the first telescopic rod 6 and the second telescopic rod 7 is released, so that the first telescopic rod 6 and the second telescopic rod 7 are extended, and then the movable plate 8 is automatically detached from the ground, thereby preventing the movable plate 8 from interfering with the movement of the trolley 1.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
