The door panel covers the front side of the enclosure, and the hinge and control unit together install the door panel on the enclosure. The rod system connects the hinge and the enclosure and pushes the door panel.

[0006] The top plate of the enclosure has an outer shaft hole on the side facing the opening, and a series of hinged rods are mounted on the outer shaft hole. A pair of through holes are located on the side of the outer shaft hole. The hinge includes a connecting piece, a corner piece, and a connecting rod. There is a pair of connecting pieces, which are connected to the upper and lower ends of the inner side of the door panel respectively. The corner piece extends from the side of the connecting piece, and the upper and lower corner pieces are connected by a pair of connecting rods. The connecting rods extend outward from the corner pieces and fit into a straight groove or an arc groove. The control unit includes a connecting hole, an inner shaft hole, a straight groove, and an arc groove. There is a pair of connecting holes, which correspond to the through holes. The control unit is fixedly installed on the inner side of the top plate and the inner side of the bottom plate using pins or other connecting parts. The side of the connecting hole has an inner shaft hole, and a series of hinged rods are mounted within the inner shaft hole. The control unit also has a straight groove and an arc groove. The arc groove is located to the side of the straight groove and connects to the middle of the straight groove to form a guide rail groove. A pair of connecting rods slide within the guide rail groove. The linkage includes a rocker arm, a crank, a pivot, and a handwheel. One end of the rocker arm is hinged to the inner connecting rod, and the other end is hinged to the crank. The other end of the crank is fixedly connected to the pivot, which passes through the inner shaft hole of the control unit and the outer shaft hole of the housing.

[0007] Furthermore, the outer surface of the door panel has a handle for gripping and opening or closing the door panel.

[0008] Furthermore, the radius of the arc groove is equal to the distance between the two connecting rods.

[0016] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0017] See Figures 1-3 The transformer enclosure door structure shown includes enclosure 10, door 20, hinge 30, control unit 40 and rod system 50. Door 20 covers the front side of enclosure 10. The hinge 30 and control unit 40 are combined to install door 20 on enclosure 10. Rod system 50 connects hinge 30 and enclosure 10 and pushes door 20.

[0018] The top plate 11 of the housing 10 has an outer shaft hole 12 on the side facing the opening, and a hinged rod system 50 is connected to the outer shaft hole 12. The side of the outer shaft hole 12 has a pair of through holes 13.

[0019] The outer surface of the door panel 20 has a handle 21 for holding and opening or closing the door panel 20.

[0020] The hinge 30 includes a connecting piece 31, a corner piece 32, and a connecting rod 33. There is a pair of connecting pieces 31, which are respectively connected to the upper and lower ends of the inner side of the door panel 20. The corner piece 32 extends from the side of the connecting piece 31. The upper and lower corner pieces 32 are connected by a pair of connecting rods 33. The connecting rods 33 extend outward from the corner piece 32 and fit into the straight groove 43 or the arc groove 44.

[0021] The control unit 40 includes a connecting hole 41, an inner shaft hole 42, a straight groove 43, and an arc groove 44. There is a pair of connecting holes 41, which correspond to the through hole 13. The control unit 40 is fixedly installed on the inner side of the top plate 11 and the inner side of the bottom plate by connecting parts such as pins. The side of the connecting hole 41 has an inner shaft hole 42, and a hinged rod system 50 is connected in the inner shaft hole 42. The control unit 40 also has a straight groove 43 and an arc groove 44. The arc groove 44 is located on the side of the straight groove 43 and communicates with the middle of the straight groove 43 to form a guide rail groove. A pair of connecting rods 33 slide in the guide rail groove.

[0022] It should be added here that the radius of the arc groove 44 is equal to the distance between the two connecting rods 33.

[0023] The lever system 50 includes a rocker arm 51, a crank 52, a pivot 53, and a handwheel 54. One end of the rocker arm 51 is hinged to the inner connecting rod 33, and the other end is hinged to the crank 52. The other end of the crank 52 is fixedly connected to the pivot 53. The pivot 53 passes through the inner shaft hole 42 of the control unit 40 and the outer shaft hole 12 of the housing 10. The handwheel 54 is fixedly connected to the outside of the outer shaft hole 12. Rotating the handwheel 54 manipulates the lever system 50 to push the hinge 30 to move and further push the door panel 20 to open and close.

[0024] Of course, it should be added that the installation of handwheel 54 can be flexibly set to one, two or even no handwheel 54 can be set, depending on the overall structure of the transformer box and the surrounding space, and the door can be opened and closed by relying solely on handle 21.

[0025] The working principle of this invention is as follows: The embodiments of this application can have two door panel opening and closing methods: one is opening and closing via handle 21, and the other is opening and closing via rotating handwheel 54. Rotating handwheel 54 causes crank 52 to rotate via shaft 53, which in turn drives rocker arm 51 to rotate. Rocker arm 51 then pushes connecting rod 33 to move. When the door panel 20 is in the open state, the position of connecting rod 33 is as shown in the attached figure. One connecting rod 33 is located in the straight groove 43, and the other is located in the arc groove 44. When the door panel 20 is closed, the connecting rod 33 located in the arc groove 44 slides within the arc groove 44. When it reaches the straight groove 43, both connecting rods 33 slide within the straight groove 43. At this time, the entire door panel 20 moves inward and covers the housing 10. When the door panel 20 is in the closed state, turn the handwheel 54 in the opposite direction, and both connecting rods 33 slide outward in the straight groove 43. At this time, the door panel 20 moves outward as a whole. Then, when one connecting rod 33 reaches the end of the straight groove 43, the other connecting rod 33 enters the arc groove 44 under the drive of the rocker arm 51. At this time, the door panel 20 flips to the side until the door panel 20 is fully opened.

[0026] The above embodiments mainly illustrate the transformer enclosure door panel structure of the present invention. Although only a limited number of embodiments and technical features have been described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its spirit and scope. Therefore, the embodiments shown are considered illustrative and not limiting, and the present invention may cover various modifications and substitutions without departing from the spirit and scope of the invention as defined by the appended claims.
