Description

Technical Field

[0001] This application relates to the technical field of electric power construction, and particularly relates to a simple and convenient wire reel. Background Art

[0002] In the field of electric power cable construction, various cables play an important role in life, including transmitting electric power, signals, etc. Before installing electric boxes and various equipment, the corresponding cables should be laid in place, so a wire reel will be used during construction.

[0003] The wire reels in the prior art generally include a bracket, a wire spool rotatably connected to the bracket for placing cables, and an adjusting structure provided on the wire spool for adapting to different inner diameters of cables. Among them, the wire spool is detachably connected to the connection, and the wire spool specifically includes two relatively arranged discs and a rotating rod provided in the middle of the discs for connection. The adjusting structure specifically includes a number of limiting rods passing through the two discs and two nuts respectively threadedly connected to both ends of the limiting rods. The discs are provided with circular holes for the limiting rods to pass through, and a number of circular holes are arranged at intervals along the radial direction of the discs to fix cables with different inner diameters for wire laying.

[0004] However, during the replacement process, when encountering wire reels with different inner diameters, it is necessary to disassemble the limiting rods and nuts and adjust them to the corresponding circular holes, and the operation is relatively long, which affects the wire laying efficiency. Therefore, further improvement is needed. Content of the Utility Model

[0005] In order to reduce the operation time, this application provides a simple and convenient wire reel.

[0006] A simple and convenient wire reel provided by this application adopts the following technical solutions:

[0007] A simple and convenient wire reel includes a bracket, a wire spool rotatably connected to the bracket for placing cables, and an adjusting structure provided on the wire spool for adapting to different inner diameters of cables; the wire reel is detachably connected to the bracket, the wire spool includes two relatively arranged discs and a screw rod passing through the middle of the two discs for connection, and one end of the screw rod is fixedly passed through one of the discs; the adjusting structure includes a first nut threadedly connected to the screw rod, a number of limiting rods passing through the two discs, and a second nut threadedly connected to one end of the limiting rod. The limiting rods are arranged at intervals along the axis of the screw rod, the first nut and the second nut are relatively arranged, one of the discs is provided with circular holes for the limiting rods to pass through, and the other disc is provided with long through holes for the limiting rods to pass through.

[0008] By adopting the above technical solution, the disc that is not fixedly penetrated by the screw is disassembled according to the inner diameter of the cable to be payed out as required. After disassembly, the cable is sleeved on several limiting rods. Then, after adjusting the position of the limiting rods at the circular holes or long through holes to abut against the inner peripheral wall of the cable, another disc is installed on the screw. At this time, the limiting rods are penetrated through the circular holes or long through holes, and then the two discs are fixed by the first nut to abut tightly against the cable.

[0009] For the circular holes and oblong holes, the first nut and the second nut, compared with the operation of threading the nuts on both sides of the penetration of the limiting rods and then connecting them to the circular holes by threads, can reduce the number of nuts to be installed, thereby reducing the operation time and further improving the pay-out efficiency.

[0010] Preferably, the ratio range between the diameter of the circular hole and the diameter of the limiting rod is 1.1 - 1.3.

[0011] By adopting the above technical solution, if the diameter formed by several limiting rods close to the circular hole is greater than or less than the inner diameter of the cable, relative movement may occur between the cable and the limiting rods. At this time, the ratio range between the diameter of the circular hole and the diameter of the limiting rod is 1.1 - 1.3, so that the diameter of the circular hole is greater than the diameter of the limiting rod. After the cable is sleeved on several limiting rods, then when adjusting the position of the limiting rods at the circular holes or long through holes, when fixing the movable disc with the second nut, one end of the limiting rod penetrating through the long through hole can tilt towards the direction of the limiting rod, so as to further improve the fixing effect on the cable, and can reduce the possibility of relative slip caused by the possible error between the diameter of the opened circular hole and the inner diameter of the cable, and can further improve the fixing effect on the cable.

[0012] Preferably, a spring is coaxially sleeved on the outer peripheral wall of the screw, and two ends of the spring respectively abut against the mutually close surfaces of the two discs, and the elastic force of the spring forces the two discs to move away from each other.

[0013] By adopting the above technical solution, during the pay-out process of the cable, the thickness of the cable may decrease. At this time, there may be relative movement between the two discs. Although two first nuts can be provided to fix the disc movably sleeved on the screw, but at this time, corresponding installation time is required. Therefore, by providing a spring, the installation time can be reduced, and the possibility that the two discs sliding under external force collide with other components and are damaged can be reduced.

[0014] Preferably, an installation plate is sleeved on the screw sliding sleeve. Connecting rods are arranged at intervals around the axis of the installation plate. The connecting rods are rotatably connected to the installation plate. The limiting rod rotatably penetrates through one end of the connecting rod away from the installation plate. The screw penetrates through the disc provided with the long through hole.

[0015] By adopting the above technical solution, by providing the installation plate and the connecting rods rotatably connected to the installation plate, when moving one of the limiting rods, other several limiting rods can be moved, playing a linkage role to accelerate the moving speed of several limiting rods, thereby reducing the operation duration.

[0016] Preferably, an elastic strip is wound around the outer peripheral wall of the limiting rod.

[0017] By adopting the above technical solution, by providing the elastic strip, the gap between the limiting rod and the cable is further filled. And under the extrusion of the limiting rod and the cable, the contact area with the cable is increased to increase the corresponding frictional force, reducing the possibility of relative slippage of the cable during the cable laying process, improving the fixing effect with the cable, and reducing the possibility of damage to the cable after being rigidly extruded by the limiting rod itself.

[0018] Preferably, both ends of the elastic strip are fixed to form an elastic ring, and the elastic rings are arranged at intervals along the length direction of the limiting rod.

[0019] By adopting the above technical solution, both ends of the elastic strip are fixed to form an elastic ring. The elastic ring is connected to the limiting rod through its own elasticity, reducing the connection difficulty between the elastic strip and the limiting rod.

[0020] Preferably, the elastic strip is arranged in a spiral shape along the length direction of the limiting rod.

[0021] By adopting the above technical solution, arranging the elastic strip in a spiral shape along the length direction of the limiting rod can reduce the time spent on installing several elastic strips. And during the winding process, there may be overlap, improving the rough surface of the outer surface of the elastic strip to further improve the fixing effect on the cable.

[0022] Preferably, second through rings are convexly arranged at both ends of the elastic strip, and hooks for the second through rings to pass through are convexly arranged on the screw.

[0023] By adopting the above technical solution, since the cable will exert a certain reaction force on the elastic strip during the cable laying process, by means of the hook and the first through ring, compared with the pasting driving method, the possibility of the elastic strip falling off after being subjected to the reaction force can be reduced.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. By providing round holes and oblong holes, and the first nut and the second nut, compared with the operation of threading the round holes on both sides of the limiting rod and then thread-connecting with the nuts, the number of nuts to be installed can be reduced, thereby reducing the operation time and further improving the wire release efficiency.

[0026] 2. Make the diameter of the round hole larger than that of the limiting rod. After sleeving the cable on several limiting rods, when adjusting the position of the limiting rod at the round hole or the long through-hole, and fixing the movable disc with the second nut, at this time, one end of the limiting rod passing through the long through-hole can be inclined towards the direction of the limiting rod to further improve the fixing effect on the cable.

[0027] 3. By providing elastic strips, the gap between the limiting rod and the cable can be further filled. Under the extrusion of the limiting rod and the cable, the contact area with the cable is increased, the corresponding frictional force is increased, the possibility of relative slippage of the cable during wire release is reduced, the fixing effect with the cable is improved, and the possibility of damage to the cable after being rigidly extruded by the limiting rod itself can be reduced.
