Detailed Description
The anti-loosening transformer tank of the present invention will now be described in greater detail with reference to the drawings, in which preferred embodiments of the present invention are shown, it being understood that those skilled in the art may modify the invention herein described while still achieving the advantageous effects of the present invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
As shown in figure 1, the anti-loosening transformer oil tank comprises a tank body 5 and a tank cover 1; the box cover 1 is positioned at an opening at the upper end of the box body 5; the box body 5 is provided with a matching threaded hole 6; an oil pipe, a low-voltage sleeve, a high-voltage sleeve, a thermometer seat, a hanging plate unit and a tap switch are arranged on the top surface of the box cover 1; the low-voltage sleeve and the high-voltage sleeve are respectively positioned at the left side and the right side of the top surface of the box cover 1; the top surface of the box cover 1 is rectangular; the top surface of the case cover 1 is evenly distributed with anti-theft bolts.
The anti-theft bolt comprises an upper section 2 and a lower section 3 which are connected in sequence; the lower section 3 is in an inverted truncated cone shape. The large end of the lower section 3 is fixed with the upper section 2; the lower section 3 is matched with a threaded hole 4 formed in the box cover 1 and a matched threaded hole 6 formed in the box body 5. Further, the anti-theft bolt is made of stainless steel.
When looseness occurs between the lower section 3 and the threaded holes 4 and the matching threaded holes 6, the anti-theft bolts are manually screwed again to fasten the box cover 1 on the box body 5.
In this embodiment, the free end of the upper section 2 forms a support 21; the upper section 2 is sleeved with a spring 22 and a sealing cylinder 23; the spring 22 is located between the support portion 21 and the seal cylinder 23; the sealing cylinder 23 covers the outside of the lower section 3. When the anti-theft bolt is screwed in again, the spring 22 presses the sealing cylinder 23 on the box cover 1 again to realize sealing again, so that the situation that a gap is generated between the box cover 1 and the box body 5 and dust and the like enter the box body 5 due to vibration between the box cover 1 and the box body 5 is avoided.
