Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 3, the door panel for the box-type transformer includes a box body 10, a door panel part 20 and a follower part 30, wherein the follower part 30 is installed inside the box body 10, and the door panel part 20 is connected with the follower part 30 and covers an opening of the box body 10.

The cabinet 10 is opened out of the door frame 11 as necessary to install the door panel part 20. Here, it should be added that, this technical scheme is more suitable for the big high little door frame of width, because the door plant of the big door frame of width will occupy great space after opening, and highly less then just in time can save the space after opening.

The door panel component 20 comprises a door panel 21, a bracket 22, a fulcrum 23, an outer bevel gear 24 and a short shaft 25, wherein the door panel 21 is covered on the door frame 11, and if necessary, a sealing strip is bonded on the outer edge of the door panel 21 to increase the sealing property. The support 22 is installed inside the door panel 21 through the fulcrum 23, the support 22 is in a cross shape, the fulcrum 23 is installed on four supports of the support 22, and the fulcrum 23 can be installed on the inner side of the door panel 21 in various firm installation modes such as screwing or bonding. An outer bevel gear 24 is fixedly mounted on the bracket 22, and the bracket 22 and the outer bevel gear 24 rotate together. The external bevel gear 24 is connected with a short shaft 25, and the rotating shaft 25 is hinged on the shaft barrel 34.

It should be added that the connection point between the bracket 22 and the door panel 21 needs to consider the height of the door panel 21 after rotation, and it needs to consider that the lower part of the door panel 21 after rotation cannot touch the ground first, and on the other hand, it needs to consider that the height of the door panel 21 after opening should be the height that can be reached by the operator, otherwise, the subsequent operation cannot be performed.

In addition, the handle can be installed on the outer side of the door panel 21 as required, of course, a sucker type handle can also be used, the handle is adsorbed when the door panel needs to be operated, and the handle does not need to be installed when the door panel is not opened, so that the space is saved.

The follow-up part 30 comprises a joint 31, a stay bar 32, an inner bevel gear 33, a shaft cylinder 34 and a shaft pin 35, the joint 31 is fixedly arranged at the side of the door frame 11, the stay bar 32 is hinged on the joint 31, the stay bar 32 is a frame-type stay bar 32, and a reinforcing rod 321 is arranged in the middle of the frame-type stay bar 32 to integrate the stay bar 32 and maintain the stability of the stay bar 32. An inner bevel gear 33 is fixedly installed at the end of the support rod 32, the inner bevel gear 33 is in meshing transmission with the outer bevel gear 24, the support rod 32 is hinged to a shaft cylinder 34 through a shaft pin 35, and the shaft cylinder 34 is a cross-shaped shaft cylinder and plays a role in rotationally connecting the follow-up component 30 and the door panel component 20. Of course, it should be added that the length of the shaft pin 35 and the length of the short shaft 25 need to be matched to avoid interference, or the shaft pin 35 may be divided into an upper part and a lower part to avoid the short shaft 24.

It should be added that the length of the brace bar 32 needs to be considered in detail, and those skilled in the art will appreciate that the length of the brace bar 32 is directly related to the mounting position of the support frame 22, and the considered point is consistent with the consideration of the mounting position of the support frame 22.

The working principle of the invention is as follows: when the door panel 21 needs to be opened, the door panel 21 is pulled outwards, and what needs to be supplemented here is that a handle can be added on the outer side of the door panel 21 according to the situation, when the door panel 21 is pulled outwards, the outer bevel gear 24 and the inner bevel gear 33 rotate mutually, the stay bar 32 rotates outwards on the joint 31, the door panel 21 rotates upwards while rotating outwards, the door panel 21 rotates upwards while opening outwards gradually, so that the door panel 21 can open the space of the door frame 11 without opening outwards completely, and necessary use and maintenance work can be completed.

The above embodiments mainly illustrate the door panel of the box-type transformer of the present invention. While only a limited number of embodiments and features have been described, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms without departing from the spirit or scope thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and various modifications and alternative arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
