Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

Examples

As shown in FIGS. 1 to 4, the present invention discloses a stable and reliable dry type transformer, which comprises a transformer body 1, a pull-out head 2 of an anti-pulling coil arranged on the transformer body 1, a buffer base 3 fixedly connected below the transformer body 1, two parallel first sliding chutes 4 arranged at the lower end of the buffer base 3, first sliding rods 5 transversely arranged along the first sliding chutes 4, a left first sliding block 6 and a right first sliding block 6 slidably mounted on each first sliding rod 5, a supporting pillar 7 slidably engaged with the lower end of the first sliding block 6, a second sliding block 8 connected with the other end of the supporting pillar 7, a buffer spring 9 arranged outside the supporting pillar 7 and having two ends connected between the first sliding block 6 and the second sliding block 8, a mounting base 10 arranged on the ground, a second sliding chute 11 arranged on the mounting base 10 and parallel to the first sliding chute 4, and a second sliding rod 12 arranged in the second sliding chute 11 and penetrating through the second sliding block 8, and a connecting rod 13 which is connected with the first slide block 6 and the second slide block 8 in a cross rotating way.

In this embodiment, first slider 6 and second slider 8 one side all are provided with recess 19, the inside fixedly connected with pivot 20 of recess 19, pivot 20 runs through connecting rod 13 and is connected with connecting rod 13 rotation.

When the transformer begins to work and vibrates to push down, the first sliding block is compressed downwards, the buffer spring is contracted, the first sliding block and the second sliding block slide towards the end directions of the first sliding rod and the second sliding rod along the first sliding rod and the second sliding rod, the connecting rods in cross connection are compressed in the vertical direction, vibration generated during the working of the transformer can be effectively counteracted through the acting force of the buffer spring, and therefore the damping effect is achieved, and noise is reduced.

In this embodiment, in order to enhance the strength of the coil head, two additional terminals are cast during the coil casting, and these two additional terminals have no electrical connection with the inside of the coil, that is, no current flows, and only share the mechanical force of the main head. As shown in fig. 2, the anti-drag coil outlet 2 includes a main outlet 14 and two sub-outlets 15, a vertical connection bar 16 having one end connected to the main outlet 14, a horizontal connection bar 17 having a middle portion connected to the other end of the vertical connection bar 16 and two ends fixed to the sub-outlets 15, and an outlet terminal 18 disposed at the intersection of the horizontal connection bar 17 and the vertical connection bar 16. When in use, the external cable is pressed on the outgoing line terminal. Therefore, the mechanical force of the cable connection position is born by the three terminals through the horizontal connection row and the vertical connection row, and the current flows into the external cable through the main outlet through the vertical row and the outlet terminal because only the main outlet is connected with the lead inside the coil. In order to ensure that the current smoothly passes through the vertical row and the outlet terminal, the material of the vertical row and the outlet terminal is made of red copper with strong conductivity. Therefore, the mechanical strength of the head is greatly improved, and the current circulation is not influenced.

Therefore, through the design, the vibration generated during the working of the transformer can be effectively counteracted through the acting force of the buffer spring, so that the vibration absorption effect is achieved, and the noise is reduced. Thus, the present invention provides substantial features and improvements over the prior art.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made within the spirit and scope of the main design of the present invention, which still solve the technical problems consistent with the present invention, should be included in the scope of the present invention.
