Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figures 1 to 4 , is an embodiment of the utility model, which provides a technical solution: a power transformer, comprising

[0022] The main body 1, four support rail seats 4 welded and fixed on the bottom surface of the main body 1, two stays 2 arranged at the bottom of the main body 1, two T-shaped seats 21 welded and fixed on the top surface of the stays 2, and T-shaped slide grooves 41 opened on the surface of the support rail seats 4, and the T-shaped seats 21 slide in the T-shaped slide grooves 41, so that the stays 2 can be slidably adjusted at the bottom of the two support rail seats 4;

[0023] The adjustment mechanism 3 disposed between the support bar 2 and the support rail seat 4 includes a rectangular sliding opening 33 provided on the surface of the support bar 2, a rectangular slider 34 slidably provided in the rectangular sliding opening 33, a limiting clamping rod 35 welded and fixed to the top surface of the rectangular slider 34, and a plurality of limiting clamping holes 36 provided on the upper wall of the T-shaped slide groove 41. The top end of the limiting clamping rod 35 passes through the T-shaped seat 21 and is inserted into one of the limiting clamping holes 36, so that the T-shaped seat 21 and the support bar 2 can be stably limited. The two ends of the rectangular slider 34 respectively pass through A shift block 31 is fixed to both sides of the support bar 2, which is convenient for the operator to pull the rectangular slider 34 and the limit clamping rod 35 through the shift block 31. The adjustment mechanism 3 also includes a limit penetrating rod 32. A through hole 37 is opened on the surface of the support bar 2. The limit penetrating rod 32 penetrates the through hole 37. The two ends of the limit penetrating rod 32 extend to both sides of the support bar 2 respectively and are at the bottom of the shift block 31. The shift block 31 can be stably supported and limited, ensuring that the limit clamping rod 35 is always stuck in the limit clamping hole 36, thereby ensuring the position stability of the support bar 2.

[0024] A rod hole corresponding to the limiting rod 35 is formed on the surface of the T-shaped seat 21 to allow the limiting rod 35 to pass through smoothly.

[0025] A rectangular opening is provided on the side of the shifting block 31 to facilitate subsequent operators to shift the shifting block 31 .

[0026] The adjusting mechanism 3 further comprises a limiting structure, which is arranged between the limiting rod 32 and the through hole 37. The limiting structure comprises an inner groove 38 provided on the upper wall of the through hole 37, a spring 39 and a semicircular telescopic card block 310 installed in the inner groove 38, and a central card hole 311 provided on the surface of the limiting rod 32. The semicircular telescopic card block 310 is movably installed in the inner groove 38 by the spring 39, and the bottom end of the semicircular telescopic card block 310 pops out into the central card hole 311, so that the limiting rod 32 can be adjusted. The limit rod 32 is engaged and limited so that the limit rod 32 will not slide out of the perforation 37 during daily use, ensuring the stability of the limit rod 32 on the shift block 31. To adjust the position of the stay 2 later, you only need to push the limit rod 32 with force so that the bottom end of the semicircular telescopic block 310 is squeezed out of the central clamping hole 311, and the limit rod 32 can be smoothly pushed out of the perforation 37. In the absence of the limit rod 32, the shift block 31 can be pulled down, so that the rectangular slider 34 can be adjusted with the limit rod 32. The positioning rod 35 moves downward, causing the top end of the limiting rod 35 to move out of the limiting hole 36, thereby releasing the limit on the T-shaped seat 21 and the stay 2. At this time, the stay 2 can be slid at the bottom of the two supporting rail seats 4 to achieve adaptive adjustment of the position of the stay 2. When the stay 2 is slid and adjusted to a suitable position, the dial block 31 is pushed up again, so that the rectangular slider 34 moves up with the limiting rod 35, and the top end of the limiting rod 35 can be inserted into the limiting hole 36 at other positions, so that the stay 2 and The T-shaped seat 21 is limited, and finally the limiting rod 32 is inserted into the through hole 37, so that the two ends of the limiting rod 32 can pass through the two sides of the support 2 and are at the bottom of the shift block 31, and the bottom end of the semicircular telescopic block 310 is inserted into the center card hole 311 under the push of the spring 39, so that the limiting rod 32 can be limited after passing through. At this time, the limiting rod 32 has its end at the bottom of the shift block 31, which can effectively block and limit the shift block 31, thereby ensuring the stability of the support 2 after the position is adjusted.

[0027] Among them, the top end of the spring 39 is fixed to the inner wall of the inner groove 38, and the bottom end of the spring 39 is fixedly connected to the semicircular telescopic block 310, thereby ensuring the installation stability of the spring 39 and the semicircular telescopic block 310.

[0028] Wherein, a plurality of heat dissipation fins are fixed on the surface of the main body 1 .

[0029] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
