Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from fig. 1 to 6, a control transformer includes a casing 1, a plurality of support legs 7 are provided at the bottom of the casing 1, a body 2 is provided in the casing 1, a fixing groove 3 for placing the body 2 is provided at the bottom of the casing 1, a plurality of connecting legs 4 are provided at the bottom of the body 2, a locking device used in cooperation with the connecting legs 4 is provided inside the casing 1, an operating handle 5 for controlling the locking device to move is provided outside the casing 1, a cover plate 6 is hinged to the top of the casing 1, the operating handle 5 cannot rotate when the cover plate 6 is closed, and the operating handle 5 can rotate when the cover plate 6 is opened to enable the locking device to unlock the connecting;

in order to conveniently use the operating handle 5 to control the locking device, the locking device comprises a locking block 8 arranged in the shell 1 in a sliding manner, the locking block 8 is matched with the connecting pin 4 after sliding, a rack 9 is fixed below the locking block 8, the rack 9 is meshed with a first gear 10, the first gear 10 is coaxially connected with a second gear 11 positioned above the inner part of the shell 1, the outer sides of the second gears 11 are connected through a gear belt 12 to form a structure that the second gears 11 synchronously rotate, the gear belt 12 is meshed with a third gear 13, the third gear 13 is coaxially fixed with a first bevel gear 14, and a second bevel gear 15 meshed with the first bevel gear 14 is fixed at the inner end of the operating handle 5; the locking block 8 is of an L-shaped structure, and the locking block 8 slides along the direction which forms an angle of 45 degrees with the side surface of the body 2.

In order to control the rotation of the operating handle 5 through the opening and closing of the cover plate 6, the third gear 13 is provided with a positioning hole 16, the top of the shell 1 is provided with a bolt 17 with the end inserted into the positioning hole 16 in a sliding manner, a spring 18 is connected between the top of the bolt 17 and the top of the shell 1, the bolt 17 is pushed upwards by the spring 18, and the movable end of the cover plate 6 is in contact with the top of the bolt 17.

When the utility model is used in a concrete way,

open apron 6, place body 2 in fixed slot 3, rotate operating handle 5 for locking device will connect foot 4 locking, thereby fix body 2 in casing 1, then close apron 6 can, when wanting to carry out components and parts and change and maintain, open apron 6 rotate operating handle 5 can.

Rotate operating handle 5, second bevel gear 15 rotates, and it rotates to drive third gear 13 with its engaged with first bevel gear 14, drives a plurality of second gears 11 synchronous rotations through gear belt 12 for a plurality of first gears 10 synchronous rotations, promote locking block 8 simultaneously and move in casing 1 is inside, and locking block 8's moving direction all is 45 with 2 sides of body, guarantees that a plurality of locking blocks 8 can pin or unblock simultaneously and connect foot 4.

The movable end of apron 6 contacts with bolt 17, press back bolt 17 behind the closed apron 6 inside 1 casing, make in the locating hole 16 of bolt 17 lower extreme inserted third gear 13, make third gear 13 can not rotate, locking device is locked unable unblock promptly, consequently can't realize the unblock to body 2 under the closed state of apron 6, avoid non-staff unblock body 2 to make body 2 produce not hard up and cause the incident, after apron 6 is opened, spring 18 promotes bolt 17, make bolt 17 bottom break away from in the locating hole 16, third gear 13 can free rotation, consequently, can change and maintain.
