Description

Technical Field

[0001] The utility model relates to the field of transformers, in particular to a power transformer fixing component. Background Art

[0002] A transformer is an electrical device that transfers AC power from one set of coils (called the "primary" or "input side") to another set of coils (called the "secondary" or "output side"). It does this by the principle of electromagnetic induction. Transformers are primarily used to change the voltage and current of AC power to meet the needs of transmission, distribution, and use of electricity.

[0003] After searching, the patent announcement number is CN211150254U, which discloses a transformer fixing seat, which includes two relatively arranged assemblies and a non-magnetic conductive assembly structure, each assembly has two assembly surfaces, the assembly surfaces of the two assemblies are opposite to each other, and the assembly structure includes a plurality of assembly units formed on the two opposite assembly surfaces, and an equal-width air gap is formed between each two opposite assembly surfaces. The transformer fixing seat of the utility model can use 3D printing and adopt high-temperature materials to form the assembly structure on the assembly surfaces of the two assemblies, so that an equal-width air gap is formed between the two assemblies, which can not only improve the processing mass production efficiency of the transformer fixing seat and improve the heat resistance effect, but also can accurately control the space size of the air gap, thereby improving the reliability, safety and voltage conversion efficiency of the transformer fixing seat.

[0004] In the existing technology, although a certain transformer installation effect can be achieved during use, there are defects: the existing transformer installation steps are cumbersome, the positioning effect is not significant, and the installation effect of engineers is affected. In view of this, we propose a power transformer fixing component to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to propose a power transformer fixing component in view of the problems existing in the background technology.

[0006] The technical solution of the utility model: a power transformer fixing component, including a base plate, a fixing mechanism 1 and a fixing mechanism 2, characterized in that: the fixing mechanism 1 is arranged at the upper end of the base plate; the fixing mechanism 2 is arranged inside the fixing mechanism 1; and there is an intermittent matching relationship between the fixing mechanism 1 and the fixing mechanism 2.

[0007] When using a power transformer fixing assembly in the present solution, first install the transformer on the upper end of the turntable and fix it using the positioning hole. After fixation, the turntable can be rotated, and the turntable follows the fixed disk to rotate in one direction and has a direction locking effect. When the position is determined, release the limit pin one, and the limit pin one is inserted into the limit hole to realize the positioning of the entire fixed disk and the turntable. At this time, the transformer is stably fixed and will not rotate.

[0008] Preferably, a mounting seat is provided on the outer wall of the base plate, and a through hole is opened on the surface of the mounting seat, and the base plate can be fixed to the ground by screws using the mounting seat.

[0009] Preferably, the fixing mechanism 1 comprises:

[0010] A mounting frame, fixedly mounted on the upper end of the bottom plate;

[0011] A ratchet wheel is rotatably mounted on the upper end of the bottom plate and is located inside the mounting frame;

[0012] Limit pins 1, a circular array is inserted into the outer wall of the mounting frame;

[0013] Spring 1, arranged between the limiting nail 1 and the outer wall of the mounting frame;

[0014] The second limiting nail is inserted into the outer wall of the mounting frame and is located below the first limiting nail;

[0015] Spring 2 is installed between the mounting frame and the limiting nail 2. The limiting nail 2 and spring 2 can cooperate with the ratchet wheel, and the ratchet wheel can rotate in one direction but cannot rotate in the opposite direction.

[0016] Preferably, the second fixing mechanism comprises:

[0017] The fixed disk is arranged inside the mounting frame. After the transformer is installed on the upper end of the rotating disk, the fixed disk is rotated. After the fixed disk rotates at a good angle, the limiting nail 1 is used to cooperate with the limiting hole so that the rotating disk and the fixed disk will not rotate relative to each other. Before this, the fixed disk and the rotating disk can be rotated in one direction to facilitate the adjustment of the position of the transformer. After the adjustment, the limiting nail 1 can be inserted into the limiting hole so that the transformer as a whole will not rotate. This scheme realizes the effect of step-by-step positioning.

[0018] A positioning hole is provided on the upper surface of the rotating disk;

[0019] A fixing frame, welded to the lower end of the fixing plate;

[0020] A turntable is fixedly mounted on the upper end of the fixed plate, and the lower edge of the outer wall of the turntable wraps around the fixed plate;

[0021] Limiting holes are formed on the outer surfaces of the rotating disk and the fixed disk.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The utility model can conveniently fix the transformer on the upper end of the turntable, and then use the limit pin 1 to fix it after the turntable is rotated to find the appropriate position.

[0024] Second, based on the first beneficial effect, only one-way rotation can be performed during the fixed period, reducing the installation instability caused by two-way rotation.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 1

[0038] See also Figures 1 to 5 As shown, this embodiment is a power transformer fixing assembly, including a base plate 100, a fixing mechanism 1 200 and a fixing mechanism 2 300, characterized in that:

[0039] The fixing mechanism 1 200 is disposed at the upper end of the bottom plate 100. The main function of the fixing mechanism 1 200 is to carry the fixing mechanism 2 300 and cooperate with the fixing mechanism 2 300 to fix the transformer installed inside the fixing mechanism 2 300.

[0040] The second fixing mechanism 300 is arranged inside the first fixing mechanism 200. The second fixing mechanism 300 is mainly used to install the transformer body, and the transformer body can be rotated and fixed inside the second fixing mechanism 300, which reduces the tedious operation of aligning the direction when starting to fix, and achieves an efficient and simple fixing effect;

[0041] The fixing mechanism 1 200 and the fixing mechanism 2 300 have an intermittent matching relationship.

[0042] The outer wall of the bottom plate 100 is provided with a mounting seat 101, and a through hole is opened on the surface of the mounting seat 101. The mounting seat 101 can be used to fix the bottom plate 100 to the ground by screws;

[0043] In this embodiment, it is convenient to fix the transformer on the upper end of the turntable 301, and then the turntable 301 is rotated to find the appropriate position and then fixed with the limiting nail 203.

[0044] Example 2

[0045] See also Figures 1 to 5 As shown, this embodiment is based on the embodiment 1 and further includes: the fixing mechanism 200 includes:

[0046] The mounting frame 201 is fixedly mounted on the upper end of the base plate 100;

[0047] The ratchet 202 is rotatably mounted on the upper end of the base plate 100 and is located inside the mounting frame 201;

[0048] Limiting pins 203, a circular array is inserted into the outer wall of the mounting frame 201;

[0052] The fixing mechanism 2 300 comprises:

[0053] The fixed disk 304 is arranged inside the mounting frame 201. After the transformer is installed on the upper end of the rotating disk 301, the fixed disk 304 is rotated. After the fixed disk 304 rotates to a desired angle, the limiting nail 203 is used to cooperate with the limiting hole 305, so that the rotating disk 301 and the fixed disk 304 will not rotate relative to each other. Before this, the fixed disk 304 and the rotating disk 301 can be rotated in one direction to facilitate adjusting the position of the transformer. After the adjustment is completed, the limiting nail 203 can be inserted into the limiting hole 305, so that the transformer as a whole will not rotate. This solution achieves the effect of step-by-step positioning.

[0057] The limiting holes 305 are formed on the outer surfaces of the rotating disk 301 and the fixed disk 304;

[0058] In this embodiment, only one-way rotation is possible during the fixed period, thereby reducing the installation instability caused by two-way rotation.
