Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer which is easy to assemble. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] As in the prior art, the patent with the patent authorization announcement number CN217426524U discloses a transformer, including an iron core, a first insulating clip, a second insulating clip and a coil, wherein the first insulating clip includes a first part, a second part and a first connecting rod, wherein the first connecting rod connects the first part and the second part, and the first part, the second part and the first connecting rod surround to form a first accommodating space, wherein the iron core portion is accommodated in the first accommodating space. The second insulating clip is provided with a second accommodating space, wherein the iron core portion is accommodated in the second accommodating space. The coil is sleeved on the iron core and is located between the first insulating clip and the second insulating clip. This transformer reduces the electrical insulation distance between the components by fixing the iron core and the coil with a detachable first insulating clip, and at the same time facilitates the maintenance of the iron core and the coil, and has the beneficial effects of compact structure, excellent economy and easy maintenance.

[0004] Although the transformer in the above patent has the beneficial effects of compact structure, good economy and easy maintenance, the existing transformer is not easy to assemble; currently, most outdoor transformers are assembled on the truss of the electric pole, and when assembling the transformer on the truss, the transformer needs to be in the middle position of the truss to avoid damage to the truss due to uneven force on the truss. Since the transformer is assembled by hoisting, workers can only calibrate the transformer by naked eye during assembly to place the transformer in the middle position of the truss. This calibration method is too rough and prone to errors, resulting in workers having to fine-tune the transformer position multiple times, which is not convenient for improving the efficiency of transformer assembly. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a transformer that is easy to assemble, so as to solve the problems raised by the background technology and make it more convenient to assemble and install the transformer body on the truss.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer that is easy to assemble, comprising a transformer main body, wherein symmetrically arranged pads are fixedly connected to the bottom of the transformer main body, and slide grooves are provided at both ends of the pads away from the transformer main body, and a slider is slidably connected inside the slide groove, and a limit plate is hingedly connected to the side wall of the slider, and a positioning plate is hingedly connected to the other end of the limit plate, and a threaded rod is fixedly connected to the side of the positioning plate close to the pad, and a threaded sleeve is provided on the outside of the threaded rod, and the threaded sleeve is rotatably connected to the pad, and a transmission component matching the threaded sleeve is connected to one side of the pad.

[0007] Furthermore, the transmission assembly includes a first transmission gear and a transmission rod, the transmission rod is rotatably connected between the two pads, both ends of the transmission rod are fixedly connected to the first transmission gear, and the outer side of the threaded sleeve is fixedly connected to a gear block matching the first transmission gear.

[0008] Furthermore, a second transmission gear is fixedly connected to the middle position of the transmission rod, an active rod is rotatably connected to one end between the two feet, a driving gear is fixedly connected to the middle position of the active rod, and chains meshing with the driving gear and the second transmission gear are sleeved on the outside.

[0009] Furthermore, outer walls at both ends of the active rod are fixedly connected with a plurality of push plates, and the push plates are equidistantly distributed.

[0010] Furthermore, the end of the sliding block is arranged in a trapezoidal shape.

[0011] Furthermore, the positioning plate is arranged in an open shape.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This type of transformer is easy to assemble. When the transformer body needs to be assembled and installed on the truss, the transformer body is first hoisted above the truss (at this time the transformer is between two electric poles). At this time, the threaded sleeves are rotated at the same time to move the two positioning plates away from the transformer body at the same time until the two positioning plates are in contact with the electric poles at the same time. At this time, the transformer body will be exactly in the middle position of the truss, eliminating the step of workers moving the transformer body, making it more convenient to assemble and install the transformer body.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-3 A transformer that is easy to assemble includes a transformer body 1. A symmetrically arranged foot 2 is fixedly connected to the bottom of the transformer body 1. Both ends of the foot 2 away from the transformer body 1 are provided with a slide groove 3. A slider 4 is slidably connected inside the slide groove 3. A limit plate 5 is hinged to the side wall of the slider 4. A positioning plate 6 is hinged to the other end of the limit plate 5. A threaded rod 7 is fixedly connected to the side of the positioning plate 6 close to the foot 2. A threaded sleeve 8 is sleeved on the outside of the threaded rod 7. The threaded sleeve 8 is rotatably connected to the foot 2. A transmission component matching the threaded sleeve 8 is connected to one side of the foot 2.

[0020] The transformer in the utility model is easy to assemble. When the transformer body 1 needs to be assembled and installed on the truss, the transformer body 1 can be first lifted above the truss by a crane (at this time the transformer is between two electric poles). At this time, the threaded sleeve 8 is rotated at the same time to make the two positioning plates 6 move away from the transformer body 1 at the same time until the two positioning plates 6 are in contact with the electric poles at the same time. At this time, the transformer body 1 will be exactly in the middle position of the truss. Then, the transformer body 1 can be placed on the truss by a crane, which saves the step of workers moving the transformer body 1, making it more convenient to assemble and install the transformer body 1. In addition, the structure of the transformer body 1 in the utility model is similar to a transformer structure disclosed in the patent authorization announcement number CN217426524U, so it will not be elaborated in detail here.

[0021] like Figure 2 and Figure 3 As shown, the transmission assembly includes a first transmission gear 9 and a transmission rod 10. The transmission rod 10 is rotatably connected between the two pads 2. Both ends of the transmission rod 10 are fixedly connected to the first transmission gear 9. The outer side of the threaded sleeve 8 is fixedly connected to a tooth block matching the first transmission gear 9.

[0022] Specifically, when the threaded sleeve 8 needs to be rotated, the transmission rod 10 can be directly rotated, and the transmission rod 10 will drive the first transmission gears 9 at both ends to rotate, and the first transmission gears 9 will drive the threaded sleeve 8 meshing therewith to rotate, thereby pushing out the positioning plate 6.

[0023] like Figure 2 and Figure 3 As shown, a second transmission gear 11 is fixedly connected to the middle position of the transmission rod 10, an active rod 12 is rotatably connected to one end between the two pads 2, a driving gear 13 is fixedly connected to the middle position of the active rod 12, and the driving gear 13 and the second transmission gear 11 are both sleeved with a chain 14 meshing therewith on the outside.

[0024] Specifically, since the transmission rod 10 is at the bottom of the transformer body 1, it is inconvenient to rotate it. At this time, the active rod 12 is directly rotated, and the active gear 13 on the active rod 12 drives the second transmission gear 11 to rotate through the chain 14, and the second transmission gear 11 will drive the transmission rod 10 to rotate. In this way, workers do not need to be at the bottom of the transformer body 1, which will be safer and more convenient.

[0025] like Figure 1 and Figure 2 As shown, the outer walls of both ends of the active rod 12 are fixedly connected with a plurality of push plates 15, and the push plates 15 are evenly distributed.

[0026] Specifically, when the active rod 12 is rotated, the push plate 15 can be used to push the active rod 12 to rotate, which is more labor-saving and convenient.

[0027] like Figure 2 As shown, the end of the slider 4 is arranged in a trapezoidal shape. The slider 4 arranged in a trapezoidal shape has a better limiting effect and is not easy to be separated from the slide groove 3.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning plate 6 is set in an open shape. The positioning plate 6 set in an open shape can better fit with the electric pole and is more convenient for positioning the transformer body 1.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
