specific Embodiment approach 1
[0025] Specific implementation mode one: refer to Figure 2 to Figure 6 Describe this embodiment in detail, the heat dissipation bracket of the cable reel socket described in this embodiment includes the active cross bar 1 and the driven cross bar 10 with the same structure, and the surface of the active cross bar 1 and the driven cross bar 10 along its length There is a slideway 11 whose cross section is "convex" in both directions, such as figure 2 with 5 shown.
[0026] Such as Figure 4 with Figure 5 As shown, a plurality of card wheel parts 3 are embedded inside the slideway 11 . The wheel part 3 includes: a roller 31, a nut 32, a screw rod 33 and a slider 34, the roller 31 is rotatably connected to one end of the screw rod 33, the nut 32 is sleeved on the screw rod 33, and the slider 34 is fixedly connected to the other end of the screw rod 33. The slide block 34 is embedded in the bottom of the "convex"-shaped slideway 11, and can slide along the length direction...

The invention provides a heat dissipation support of a cable drum socket, and relates to the technical field of electric power. The heat dissipation support aims to solve the problem that an existing cable drum socket is not easy to dissipate heat. The heat dissipation support of the cable drum socket is characterized in that the surfaces of a driving cross rod and a driven cross rod are each provided with a sliding way in the length direction, a plurality of wheel clamping parts are embedded in each sliding way, rollers are rotatably connected with sliding blocks, the sliding blocks are embedded in the sliding ways and can slide along the sliding ways, and the rollers are located outside the sliding ways; two ends of the driving cross rod and the driven cross rod are separately provided with a swing rod groove, a motor is fixedly embedded in each of the two swing rod grooves of the driving cross rod, a rotating shaft of each motor is connected with a driving swing rod, the motors can drive the driving swing rods to extend out of or retract into the swing rod grooves after being started, a driven swing rod is hinged into each of the two swing rod grooves of the driven cross rod, and the driving cross rod and the driven cross rod are arranged in a mirror symmetry mode; and the driving swing rod and the driven swing rod which are opposite to each other are hinged through a hinge wheel, and the circle center of the hinge wheel deviates from the center axis of the driving swing rod and the center axis of the driven swing rod.
Description
technical field [0001] The invention belongs to the field of electric power, in particular to a cable reel. Background technique [0002] Cables are devices used in the electrical field for the transmission of electrical energy. In some power construction sites, some electrical equipment is far away from a fixed power source, making it unusable. Therefore, the operator usually chooses the cable reel socket to connect the power supply with the electrical equipment. [0003] The cable reel socket winds the long cable on the roller, and properly retracts and unwinds according to the distance between the electrical equipment and the power supply. In the actual application process, there are often situations where the distance is not far and the cable does not need to be fully stretched for use. However, when the electric power is too large, the cable will generate heat, and the unexpanded part wound on the roller is not easy to dissipate heat, which will prompt the overheatin...
