DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1

[0024] See also Figures 1 to 6 In an embodiment of the utility model, a lead structure of a power transformer includes a conductive lead 300 and a storage shell 100. The storage shell 100 is equipped with a winding wheel 200. A partition 220 is fixedly connected to the middle position of the outer wall of the winding wheel 200, and winding grooves 210 are arranged on the outer walls of the winding wheel 200 at both sides of the partition 220. The conductive lead 300 is spirally wound on the two winding grooves 210, and the spiral directions of the wound parts of the conductive lead 300 on the two winding grooves 210 are opposite. The storage shell 100 is used to load the winding wheel 200. A cover plate 150 is rotatably connected to one side of the top of the storage shell 100, and one side of the cover plate 150 is detachably fixed to the other side of the top of the storage shell 100. A driving module 140 is arranged on one side wall of the storage shell 100, and two ends of the conductive lead 300 pass through the two ends of the storage shell 100 respectively.

[0025] Specifically, the middle position of the conductive lead 300 is clamped in the position of the clamping groove 221, and then the two sides of the middle position of the conductive lead 300 are respectively wound on the two winding grooves 210, the cover 150 is opened, the winding wheel 200 is placed in the storage shell 100, the cover 150 is covered, and the cover 150 is fixed. When the effective length of the conductive lead 300 needs to be extended, the conductive lead 300 is directly pulled, and the two ends of the conductive lead 300 pull the winding wheel 200 to rotate forward, thereby releasing the conductive lead 300. When the conductive lead 300 needs to be retracted, the driving module 140 drives the winding wheel 200 to rotate in the opposite direction, so that the two ends of the conductive lead 300 are simultaneously reeled up by the winding wheel 200, thereby realizing the retraction and release of the conductive lead 300, and facilitating the adjustment of the effective length of the conductive lead 300 as needed.

[0026] like Figures 1 to 6 As shown, in the present embodiment, a snap-in groove 221 is provided on one side wall of the partition 220, and the snap-in groove 221 is used to snap-in the conductive lead 300, and two protrusions 240 are fixedly connected to the outer edge of one side wall of the winding wheel 200, and the driving module 140 includes an axle rod 142, and the axle rod 142 is rotatably sleeved with the outer side wall of the other side of the storage shell 100, and one end of the axle rod 142 is fixedly connected with a deflection frame 141, and the other end of the axle rod 142 is fixedly connected with a knob 143, and an axle rod 230 is fixedly sleeved in the middle position of the winding wheel 200, and a positioning frame 130 is fixedly connected to the inner wall of one side of the storage shell 100, and the open end of the positioning frame 130 faces upward, and a guide wheel 110 is rotatably connected between one ends of the inner side walls on both sides of the storage shell 100, and the guide wheel 110 is used to guide one end of the guide wheel 110.

[0027] During specific implementation, when the winding wheel 200 is placed in the storage shell 100, one end of the second shaft rod 230 slides into the bottom end of the positioning frame 130, thereby facilitating the rotation of the winding wheel 200 and avoiding the winding wheel 200 from being stuck. At the same time, through the setting of the deflection frame 141, when the winding wheel 200 is placed and taken out, the deflection frame 141 is driven to rotate through the knob 143, so that the deflection frame 141 is deflected to a vertical state, thereby avoiding the interference of the deflection frame 141 with the two protrusions 240. When it is necessary to drive the winding wheel 200 to rotate in the opposite direction, the protrusion 240 is directly pushed by the deflection frame 141 to drive the winding wheel 200 to rotate.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, the conductive lead 300 is fixed.

[0030] like Figures 1 to 6As shown, in this embodiment, the inner bottom surfaces at both ends of the storage shell 100 are fixedly connected with support blocks 120, and the two support blocks 120 correspond to the two winding grooves 210 respectively, the inner bottom surface of the cover plate 150 is rotatably connected with a screw rod 151, and both ends of the screw rod 151 are provided with screw grooves, and the inner top surface of the cover plate 150 is provided with square grooves 154 at the positions corresponding to the two support blocks 120, and the inner wall of the square groove 154 is slidably sleeved with an extrusion block 153, and the top of the extrusion block 153 is an inclined surface, and the inner bottom surface of the cover plate 150 is slidably connected with a push block 152 at both ends, one end of the push block 152 fits with the top of the adjacent extrusion block 153, and the push block 152 is screwed together with the screw rod 151.

[0031] During specific implementation, the conductive lead 300 is clamped between the support block 120 and the corresponding extrusion block 153, thereby fixing the conductive lead 300. Before adjusting the effective length of the conductive lead 300, the screw rod 151 is rotated to make the two push blocks 152 approach each other, so that one end of the push block 152 relaxes the extrusion on the extrusion block 153, thereby making the extrusion block 153 relax the extrusion on the conductive lead 300, which is convenient for subsequent adjustment of the effective length of the conductive lead 300. The screw rod 151 is rotated in the opposite direction to make the push block 152 move horizontally downward to squeeze the extrusion block 153, and then the conductive lead 300 is clamped and fixed by the extrusion block 153 and the support block 120, thereby achieving the limitation of the conductive lead 300.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
