[0030] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figures 1 to 8 As shown, a specific embodiment of the present invention discloses a wire reel for electric power engineering, including a wire reel 100, a frame 200, and a swing frame 300; the wire reel 100 is rotatably mounted on the frame 200, and a rotating shaft 110 is provided at the center of the end face of the wire reel 100 away from the socket, and a first gear 120 is installed at the end of the rotating shaft 110; the swing frame 300 includes two support bars 310 arranged opposite to each other, and a roller 320 is rotatably mounted at one end of the two support bars 310 for rolling support of the unwound wire; the other end of the support bar 310 is rotatably mounted on the frame 200, and the rotation fulcrum is located on the side of the first gear 120 away from the handle 236 of the frame; a rack portion 311 is provided on the support bar 310 adjacent to the first gear 120, and when the swing frame tilts toward the handle side, the rack portion meshes with the first gear to form a locking effect on the wire reel; when the wire needs to be unwound, the rack portion disengages from the first gear, and the swing frame tilts toward the side away from the handle, so that the roller is maintained in an overhead position.

[0032] In the above-mentioned wire reel for electric power engineering, a first gear is installed on the rotating shaft of the wire reel away from the socket; a rack portion is provided on the support bar of the swing frame adjacent to the first gear, and when the swing frame tilts toward the handle side, the rack portion meshes with the first gear to form a locking effect on the wire reel; this can effectively prevent the wire reel from accidentally rotating when the whole reel is moving or when there is no need to release the wire, and prevent the wire from being detached when not in use;

[0033] When the wire needs to be unwound, the swing frame is tilted outward to disengage the rack portion from the first gear, thereby achieving an unlocking action. The wire drum can then rotate normally to satisfy the required winding and unwinding actions. Moreover, when the swing frame is tilted toward the side away from the handle, the roller is maintained in an overhead position to provide guiding and rolling support for the wire, so that the wire is in a relatively tight state during the winding process, thereby achieving a tight winding effect.

[0034] Furthermore, if Figure 6 , Figure 7 As shown, the frame 200 includes a main frame body 230, a first support frame 210, and a second support frame 220; the main frame body 230 includes a stand 231 and two oppositely arranged arch frames 232, the arch frames 232 are fixedly arranged on both sides of the stand 231, the first support frame 210 is installed in the middle of one of the arch frames 232, and the second support frame 220 is installed at the bottom of the other arch frame 232; the middle of the first support frame 210 is provided with a first through hole 211 adapted to the rotating shaft 110; the top of the second support frame 220 is an arc-shaped structure, and forms a closed-loop limiting hole 240 with the corresponding arch frame top; as shown Figure 3 , Figure 4 As shown, a limiting ring 130 is fixedly provided on the end face of the wire drum 100 away from the rotating shaft 110, and the limiting ring 130 is adapted in shape to the limiting hole 240; the wire drum is rotatably installed between the first support frame and the second support frame; the bottom of the arch frame is open, so that the wire drum can be moved upward from the bottom position to be inserted, and then the first support frame and the second support frame are installed to rotatably install the wire drum; wherein, since a socket is required to be set at one end of the wire drum, which occupies its central part, a limiting ring is set at the edge position, and an adapted limiting hole is formed by the cooperation of the second support frame and the arch frame, so that the end of the wire drum is rotatably supported; as shown in FIG. Figure 1 , Figure 2 As shown, the other end realizes rotational cooperation through the cooperation of the rotating shaft and the first through-hole, thereby completing the rotational support of the entire cable drum; it should be pointed out that the socket, corresponding wiring slots and holes arranged on the cable drum are common in cable reels, and the details are not repeated here.

[0035] Furthermore, the first support frame 210 is provided with a first threaded hole 212 on the side of the first through-hole away from the vertical frame; a support plate 221 is fixedly provided on the second support frame 220, and a second threaded hole 222 is provided on the support plate 221, and the second threaded hole 222 corresponds to the position of the first threaded hole 212; a second through-hole 312 is provided on the end of the support bar 310 away from the roller 320; the two support bars are respectively installed at the corresponding first threaded hole and the second threaded hole through the first support bolt passing through the second through-hole, and the swing frame 300 uses the two first support bolts 410 as rotation fulcrums; this structural design provides two symmetrical rotation fulcrums for the swing frame, ensuring that the swing frame rotates and swings smoothly, and also enables it to swing accurately to the desired position; and this structure can also enhance its overall support strength, providing good support for the retraction and release of the wires.

[0036] Furthermore, if Figure 8 , Fig. 9 As shown, the roller 320 includes a support tube 321, two retaining rings 322 fixedly mounted on the support tube 321, which limit the range of movement of the guide and prevent the wire from running into the winding area; a weight sleeve 323 is fixedly mounted on the support tube between the two retaining rings 322, and the design of the weight sleeve makes it have enough weight as a whole, and mainly utilizes the weight to tilt the top downward, so that the swing frame maintains a certain placement position; the support tube 321 is rotatably mounted between the two support bars 310 through the shaft bar 330, and the entire roller is rotatably mounted on the top of the swing frame to provide rolling support for retracting and discharging the wire; a spacing is left between the retaining ring and the support bar; as shown Figure 6 As shown, a hanging plate 233 is fixedly arranged at both ends of the vertical frame 231 to fix the corresponding roller, and a bayonet 234 is formed between the hanging plate 233 and the vertical frame 231, which is used to set up a supporting support tube 321, so that the top of the swing frame is against the vertical frame to prevent the swing frame from easily detaching from the bayonet, and maintain the required locking state; a first support column 235 is fixedly arranged on the outer wall of the arch frame 232, and the first support column 235 is located above the side of the first support bolt 410 away from the vertical frame 231, and the angle between the center line of the first support column and the first support bolt and the horizontal plane is between 40° and 55°, and the extended length of the first support column is sufficient to support the corresponding support bar, and the first support column is used as the supporting part for the swing frame to be placed outward, and the above angle is limited so that when the support bar is against the first support column, the angle of the support bar is between 45° and 60°, so that the roller is at a suitable height position and inclination position, and the gravity of the counterweight sleeve is used to apply downward force to prevent the swing frame from easily swinging during the wire unwinding process, so as to maintain an effective guiding effect.

[0037] Furthermore, a second support column 213 is fixedly provided on the first support frame 210, and the second support column 213 is arranged on one side of the first threaded hole 212; a circular plate 313 is fixedly provided on the end of the support bar 310 away from the roller, and the second through hole 312 is arranged at the center of the circular plate 313, and the outer wall of the circular plate 313 slides against the outer wall of the second support column 213; when the support bar swings to abut against the first support column, the bottom of the support bar abuts against the second support column; on the one hand, the swing of the support bar close to the side of the first support frame can be limited, and on the other hand, the support for the support bar on this side can be further strengthened, thereby enhancing the supporting effect on the swinging frame that swings outward.

[0038] Furthermore, a third threaded hole 214 is provided on the first support frame 210, and the third threaded hole 213 is located on a side of the first through hole 211 close to the stand 231; a second gear 500 is provided on one side of the first gear 120, and the second gear 500 is rotatably mounted on the third threaded hole 214 through a second support bolt 420; the diameter of the second gear 500 is greater than the diameter of the first gear 120, and the second gear 500 is meshed with the first gear 120 for transmission; a handle 510 for grasping is fixedly provided at the edge of the second gear 500; the rotation of the wire drum is adjusted by increasing the gear ratio, and rotating the second gear one circle can drive the wire drum to rotate multiple circles, which is convenient for winding and releasing the line.

[0039] Furthermore, rollers 600 are installed on both sides of the bottom of the stand 231, and the bottom of the rollers is lower than the bottom of the frame; the handle 236 is fixed on the top of the stand 231; it can be used as a rolling support for the movement of the entire cable reel, which is convenient for movement in actual operations; when in use, grasp the handle, tilt the frame to one side in the direction of the stand, and use the rollers as the only grounding structure to drag the entire cable reel to move, which is convenient for practical applications.
