[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery, and other applications. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF).
[0003] However, many transformers now require multiple adjustments to the nuts during assembly, increasing assembly time and making the assembly process more cumbersome. Utility Model Content
[0004] This utility model provides a novel nut structure for assembling dry-type transformers, aiming to solve the problem that many current transformers require multiple adjustments to the nut during assembly, increasing assembly time and making the assembly process more cumbersome.
[0005] This utility model is implemented as follows: a novel nut structure for assembling a dry-type transformer includes: a T-shaped retaining nut; a bolt threaded into the T-shaped retaining nut; and a fastening mechanism disposed on the top of the T-shaped retaining nut. The fastening mechanism can be used to secure the bolt when it is screwed into the T-shaped retaining nut.
[0006] Preferably, the fastening mechanism includes: a connecting plate fixedly connected to the top of the T-shaped clip nut, a slide rod slidably connected inside the connecting plate, a side plate with a "V" shape fixedly connected to one side of the slide rod, and a first spring fixedly connected to the slide rod on one side of the connecting plate.
[0007] Preferably, a rubber ring is fixedly connected to the top of the T-shaped clip nut, which can be used to increase the tightness of the bolt.
[0008] Preferably, an anti-slip strip is fixedly connected to the surface of the T-shaped clip nut, which can be used to enhance the frictional resistance between the T-shaped clip nut and the bottom of the upper clamp.
[0009] Preferably, the anti-slip protrusions are fixedly connected to the side of the T-shaped clip nut, and the anti-slip protrusions can be used to increase the frictional resistance with the opening position of the upper clamp.
[0010] Preferably, an oil hole is provided inside the T-shaped retainer nut, which facilitates the injection of lubricating oil into the T-shaped retainer nut.
[0011] Preferably, a second spring is fixedly connected to the side of the T-shaped clip nut, and a limiting plate is fixedly connected to one end of the second spring. The limiting plate can be used to limit the top of the upper clamp.
[0012] Preferably, a telescopic rod is fixedly connected to one side of the limiting plate and to a T-shaped clip nut. The telescopic rod can be used to limit the movement trajectory of the limiting plate.
[0013] Preferably, a sturdy stabilizing plate is fixedly connected to the bottom of the T-shaped clip nut, which can be used to improve the stability between the bottom of the T-shaped clip nut and the pad.
[0014] Compared with related technologies, the novel nut structure for dry-type transformer assembly provided by this utility model has the following advantages:
[0015] By setting a fastening mechanism, the fastening mechanism can control the side plate 8 to move to the contact position with the bolt 2, thereby limiting the bolt 2 and preventing it from loosening. The anti-slip strip 9 can be used to enhance the frictional resistance between the T-shaped clip nut 1 and the bottom of the upper clamp, and the anti-slip protrusion 10 can be used to increase the frictional resistance with the opening position of the upper clamp. Both can improve the stability of the T-shaped clip nut 1 after assembly. Under the action of the oil hole 4, it is set at an angle. When lubricating oil is injected into the oil hole 4, it can play a lubricating role, which makes it easier for the bolt 2 to be unscrewed from the inside of the T-shaped clip nut 1.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] This utility model embodiment provides a novel nut structure for assembling dry-type transformers, such as... Figure 1-5 As shown, a novel nut structure for assembling a dry-type transformer includes: a T-shaped retaining nut 1; a bolt 2 threadedly connected inside the T-shaped retaining nut 1; and a fastening mechanism located on the top of the T-shaped retaining nut 1. The fastening mechanism can be used to secure the bolt 2 when it is screwed into the T-shaped retaining nut 1.
[0025] In a further preferred embodiment of the present invention, the fastening mechanism includes: a connecting plate 5 fixedly connected to the top of the T-shaped clip nut 1, a slide rod 6 slidably connected inside the connecting plate 5, a side plate 8 with a "V" shaped structure fixedly connected to one side of the slide rod 6, and a first spring 7 fixedly connected to the slide rod 6 on one side of the connecting plate 5.
[0026] In this embodiment, the bolt 2 is screwed into the T-shaped clip nut 1 and then embedded into the opening of the upper clamp. The bolt 2 is adjusted by a wrench to control its extension length, thereby achieving the function of fastening the pad. Under the action of the fastening mechanism, after the bolt 2 is assembled, the side plate 8 can be loosened without manually fixing it. At this time, the first spring 7 will push the slide rod 6 forward, and then the slide rod 6 will push the side plate 8 forward, so that the side plate 8 and the bolt 2 fit tightly together, thereby avoiding the problem of the bolt 2 loosening after tightening.
[0027] In a further preferred embodiment of this utility model, a rubber ring 3 is fixedly connected to the top of the T-shaped clip nut 1. The rubber ring 3 can be used to increase the tightening degree of the bolt 2.
[0028] In this embodiment, by setting the rubber ring 3, the rubber ring 3 can make the bolt 2 fit tightly against itself when tightened, thereby improving the stability of the bolt 2 after tightening.
[0029] In a further preferred embodiment of the present invention, an anti-slip strip 9 is fixedly connected to the surface of the T-shaped clip nut 1. The anti-slip strip 9 can be used to enhance the frictional resistance between the T-shaped clip nut 1 and the bottom of the upper clamp.
[0030] In this embodiment, the anti-slip strip 9 is arranged in an intersecting "X" shape. After the T-shaped clip nut 1 is inserted into the opening of the upper clamp, the T-shaped clip nut 1 can enhance the friction between itself and the upper clamp, thus preventing the T-shaped clip nut 1 from shaking.
[0031] In a further preferred embodiment of this utility model, the anti-slip protrusion 10 fixedly connected to the side of the T-shaped clip nut 1 can be used to increase the frictional resistance with the opening position of the upper clamp.
[0032] In this embodiment, by setting anti-slip protrusions 10, the anti-slip protrusions 10 can enhance the anti-slip properties of the side of the T-shaped nut 1 and further improve the stability of the T-shaped nut 1.
[0033] In a further preferred embodiment of the present invention, an oil hole 4 is provided inside the T-shaped retaining nut 1, which facilitates the injection of lubricating oil into the T-shaped retaining nut 1.
[0034] In this embodiment, the oil hole 4 is inclined, so that when lubricating oil is injected into the oil hole 4, the bolt 2 can be easily unscrewed from the T-shaped nut 1.
[0035] In a further preferred embodiment of this utility model, a second spring 11 is fixedly connected to the side of the T-shaped clip nut 1, and a limiting plate 13 is fixedly connected to one end of the second spring 11. The limiting plate 13 can be used to limit the top of the upper clamp.
[0036] In this embodiment, by setting a limiting plate 13, under the action of the second spring 11, the limiting plate 13 can be pushed to fit against the upper clamp, thereby limiting the top of the upper clamp.
[0037] In a further preferred embodiment of the present invention, a telescopic rod 12 is fixedly connected to one side of the limiting plate 13 and fixedly connected to the T-shaped clip nut 1. The telescopic rod 12 can be used to limit the movement trajectory of the limiting plate 13.
[0038] In this embodiment, under the action of the telescopic rod 12, the limiting plate 13 can slide horizontally, avoiding the problem of the limiting plate 13 tilting under force, and improving the stability of the limiting plate 13 in stabilizing the upper clamp.
[0039] In a further preferred embodiment of the present invention, a sturdy stabilizing plate 14 is fixedly connected to the bottom of the T-shaped clip nut 1. The stabilizing plate 14 can be used to improve the stability between the bottom of the T-shaped clip nut 1 and the pad.
[0040] In this embodiment, the bottom of the stabilizing plate 14 is designed with a frosted finish, which can further improve the stability of the T-shaped clip nut 1 during assembly when the bottom of the T-shaped clip nut 1 is in contact with the pad.
[0041] Compared with related technologies, by setting a fastening mechanism, the fastening mechanism can control the side plate 8 to move to the contact position with the bolt 2, thereby limiting the bolt 2 and preventing it from loosening. The anti-slip strip 9 can be used to enhance the frictional resistance between the T-shaped clip nut 1 and the bottom of the upper clamp, and the anti-slip protrusion 10 can be used to increase the frictional resistance with the opening position of the upper clamp. Both can improve the stability of the T-shaped clip nut 1 after assembly. Under the action of the oil hole 4, it is set at an angle. When lubricating oil is injected into the oil hole 4, it can play a lubricating role, which makes it easier for the bolt 2 to be unscrewed from the inside of the T-shaped clip nut 1.
