[0003] In order to make better use of the cable reel, a fixing device will be set on the cable reel, such as a simple construction site formal cable reel fixing device disclosed in the authorization announcement number CN217010120U. It provides a bracket that is easy to transport as a fixing device to limit the cable reel, ensuring that the position of the cable reel is limited under the premise that the cable reel can rotate. At the same time, it adopts movable two-way lifting ears to facilitate the disassembly and transportation of the fixing device. The whole device has a low manufacturing cost and can be operated in conjunction with a crane, which is suitable for large-scale production.

[0004] When installing the fixed disc as mentioned above, it is necessary to use a crane to lift the cable disc into the air, pass the rotating rod through the casing and the cable disc, and separate the cable disc from the crane to complete the installation operation. However, the rotating rod is connected to the casing and its cable disc by plugging, and there is no locking mechanism between the casings of the cable disc. The cable disc is easy to move when it is lifted, which may cause the cable disc to be lifted unstable or even fall. For this reason, we propose a cable disc fixing device. Utility Model Content

[0025] 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.

[0026] The utility model provides Figure 1-5A cable drum fixing device shown in the figure comprises a cable drum 1 and a support rod 2 located below the cable drum 1, a locking mechanism for locking the cable drum 1 is arranged on the top of the support rod 2, and the locking mechanism comprises: a fixed sleeve 3, the fixed sleeve 3 is fixedly connected to the top end of the support rod 2; a locking assembly 4, the locking assembly 4 is threadedly connected to one end of the fixed sleeve 3, the end of the locking assembly 4 is rotatably connected to a plug rod 6, and the plug rod 6 is used to plug the cable drum 1; a top ring 7, the top ring 7 is fixedly connected to the middle part of the plug rod 6; a movable sleeve 8, the movable sleeve 8 is slidably arranged inside the fixed sleeve 3, and the top ring 7 drives the movable sleeve 8 to move, and one end of the movable sleeve 8 is fixedly connected to a plug for squeezing the cable drum 1. The number of the squeezing ring 9 and the fixing sleeve 3 of the cable drum 1 is set to two; when the cable drum 1 needs to be connected to the entire fixing device, the cable drum 1 is lifted and moved between the two fixing sleeves 3, and the locking component 4 is moved so that the locking component 4 drives the insertion rod 6 and its top ring 7 to move, so that the insertion rod 6 is inserted into the cable drum 1, and the top ring 7 drives the movable sleeve 8 and its squeezing ring 9 to move, so that the squeezing ring 9 squeezes the side of the cable drum 1, and then the locking component 4 is rotated so that the locking component 4 is threadedly connected to the fixing sleeve 3, so that the squeezing ring 9 fixes the cable drum 1, so that the cable drum 1 will not move easily when lifted, thereby avoiding accidents.

[0027] It should be further explained that the interior of the fixed sleeve 3 is composed of a circular cavity 301 opened in the middle of the fixed sleeve 3 and a threaded hole 302 opened on one side of the circular cavity 301; the locking assembly 4 includes a locking ring 401 threadedly connected to the inside of the threaded hole 302 and a plurality of protrusions 402 fixedly connected to the outside of the locking ring 401; when the locking assembly 4 needs to be locked, the protrusion 402 is rotated so that the protrusion 402 drives the locking ring 401 to rotate, thereby connecting the locking ring 401 to the threaded hole 302, thereby fixing the position of the insertion rod 6 and its extrusion ring 9 with the locking assembly 4.

[0028] Furthermore, the insertion rod 6 passes through the circular cavity 301 and one end of the extrusion ring 9 in sequence and is plugged into the middle of the cable drum 1, and the inner diameter of the middle of the cable drum 1 is adapted to the outer diameter of the insertion rod 6; this facilitates the stable plugging of the insertion rod 6 and the cable drum 1, thereby avoiding a large gap between the insertion rod 6 and the cable drum 1, which causes a large shaking of the cable drum 1 when it is lifted.

[0029] Furthermore, the outer diameter of the top ring 7 is smaller than the inner diameter of the threaded hole 302, which facilitates the reversal of the locking ring 401. After being separated from the threaded hole 302, when the locking assembly 4 is moved outward, it is convenient to drive the top ring 7 and its insertion rod 6 out of the fixed sleeve 3. The outer diameter of one end of the movable sleeve 8 is compatible with the inner diameter of the circular cavity 301, so that the movable sleeve 8 can move stably along the inside of the circular cavity 301.

[0030] Furthermore, a rotating cylinder 5 is provided for internal rotation of the locking assembly 4, and the locking assembly 4 is connected to the insertion rod 6 through the rotating cylinder 5. The rotating cylinder 5 is composed of a rotating cylinder connected to the internal rotation of the locking ring 401 and two limiting round blocks fixedly connected to the corresponding end faces of the rotating cylinder respectively; when the locking assembly 4 is rotated, the locking ring 401 can rotate along the rotating cylinder 5.

[0031] It should be noted that a clamping mechanism is provided between the top ring 7 and the movable sleeve 8, and the clamping mechanism includes an annular block 12 fixedly connected to the outer surface of the top ring 7, an annular clamping block 13 fixedly connected to one side of the annular block 12, an annular rubber sleeve 10 provided on the outside of the annular clamping block 13, and an annular clamping groove 11 provided on the end face of the movable sleeve 8, and the cross-sectional profile of the annular clamping block 13 is set to be spherical; when the top ring 7 approaches it to push the movable sleeve 8 until the squeezing ring 9 squeezes the cable disc 1, the annular clamping block 13 is clamped into the annular clamping groove 11, so that the annular rubber sleeve 10 is provided on the outside of the annular clamping block 13, and the annular clamping groove 11 is provided on the end face of the movable sleeve 8. The rubber sleeve 10 is deformed and inserted into the annular groove 11, thereby completing the engagement between the annular block 13 and the annular groove 11. At this time, it is also convenient for the top ring 7 to push the extrusion ring 9 to extrude the cable disc 1. When the locking assembly 4 is separated from the fixed sleeve 3, the locking assembly 4 is moved outward, so that the top ring 7 drives the movable sleeve 8 and its extrusion ring 9 to move, so that the top ring 7 drives the extrusion ring 9 away from the cable disc 1 until the extrusion ring 9 abuts against the fixed sleeve 3. At this time, the annular block 13 is separated from the annular groove 11, so as to facilitate the insertion rod 6 to move further outward.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
