DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1 As shown, the utility model proposes a dry-type transformer that is easy to maintain, which includes a protective shell 1. The front end of the bottom of the protective shell 1 is connected to the protective front cover 2 through a hinge 12. A mounting plate 3 is movably arranged in the protective shell 1, and a transformer body 5 is arranged on the mounting plate 3. A driving component 4 is arranged at the bottom of the protective shell 1, and the driving component 4 is transmission-connected to the mounting plate 3.

[0022] like Figure 2-Figure 3 As shown, a pair of first slide rail grooves 10 are provided on the inner bottom surface of the protective shell 1, a pair of through grooves 11 are provided between the two first slide rail grooves 10, fixing grooves 13 are provided on both side walls of the front end surface of the protective shell 1, a connecting piece 14 is provided in the fixing groove 13, and a movable hole 15 that penetrates the protective shell 1 is also provided on the side wall of the protective shell 1.

[0023] like Figure 4 As shown, the outer wall of the protective front cover 2 is provided with a pair of supporting feet 20, and the inner wall of the protective front cover 2 is provided with a pair of connecting members 22. The connecting member 22 is movably connected to the top of the telescopic rod of the telescopic electric cylinder 6. The tail of the telescopic electric cylinder 6 is movably set on the connecting member 14. Two second slide rail grooves 21 corresponding to the first slide rail grooves 10 are also opened on the protective front cover 2 between the two connecting members 22.

[0024] like Figure 5 As shown, a pair of slide rails 30 are provided at the bottom of the mounting plate 3 , and the slide rails 30 are slidably arranged in the first slide rail groove 10 . Two rows of transmission teeth 31 located above the through groove 11 are provided on the mounting plate 3 between the two slide rails 30 .

[0025] like Figure 6 As shown, the driving assembly 4 includes a motor 40 arranged on the side wall of the protective shell 1, and a transmission rod 41 is arranged at the transmission end of the motor 40.
