[0042] In the initial position, neither the driving gear 1 132 nor the driving gear 2 133 contacts the teeth on the driving circular plate 137. The unfolding motor 140 is started to drive the driving circular plate 137 to rotate. By controlling the forward and reverse rotation of the driving circular plate 137, the driving circular plate 137 is engaged with the driving gear 1 132 and the driving gear 2 133 respectively.

[0045] The unfolding motor 140 is started to drive the driving circular plate 137 to rotate. The teeth on the driving circular plate 137 engage with the driving gear 1 132. Under the action of the driving circular plate 137, the driving gear 1 132 rotates. At this time, the driving gear 2 133 cannot rotate. The driving pulley 134 on the driving gear 1 132 rotates synchronously. Then, under the action of the driven belt 1 126, the driven pulley 1 125 and the driven pulley 2 131 corresponding to the driving gear 1 132 both rotate, and the linkage gear corresponding to the driving gear 1 132 rotates. 130 rotates synchronously, and the driven gear 129 corresponding to the linkage gear 130 also rotates synchronously.

Under the action of the driving circular plate 137, the driving gear 2 133 rotates. At this time, the driving gear 1 132 cannot rotate. Similarly, the rotation directions of the two cabinet doors 102 in the shielding assembly corresponding to the driving gear 2 133 are opposite, that is, the two cabinet doors 102 in the shielding assembly corresponding to the driving gear 2 133 are opened synchronously.

The two internal support racks 120 are symmetrically slidably installed on the partition plate 105. The diamond-shaped rotating block 122 is rotatably installed on the partition plate 105. The end of the internal support rack 120 closest to the corresponding diamond-shaped rotating block 122 is fixedly provided with an internal support push plate 121. The diamond-shaped rotating block 122 is used to push the corresponding two internal support push plates 121 to move. An internal support gear 123 is fixedly provided on the strip support plate 108. The internal support gear 123 is engaged with the corresponding internal support rack 120 to form a gear rack pair.

[0048] In the initial position, the torsion spring between the partition plate 105 and the strip support plate 108 is not compressed. At this time, the two inner support push plates 121 in the same support assembly are located at the closest position to each other. At this time, the two strip support plates 108 in the same support assembly form an X shape, and at this time the lower end of the strip support plate 108 is engaged with the corresponding groove on the shell 101. Under the action of the groove on the shell 101, the strip support plate 108 is auxiliary supported. The strip support plate 108 closest to the cabinet door 102 in the same support assembly contacts the inner surface of the cabinet door 102.

[0050] When the driving gear 132 or the driving gear 2 133 is driven to rotate, the diamond-shaped rotating block 122 rotates synchronously under the action of the auxiliary pulley 135, the auxiliary belt 136, and the auxiliary pulley 2 138. Under the action of the diamond rotating block 122, the two inner support push plates 121 corresponding to the diamond rotating block 122 move in the directions away from each other, that is, the two inner support racks 120 corresponding to the diamond rotating block 122 move in the directions away from each other, and the two inner support gears 123 corresponding to the diamond rotating block 122 both rotate, and the rotation directions of the two inner support gears 123 are opposite, and the strip support plates 108 corresponding to the inner support gears 123 rotate synchronously, that is, the ends of the strip support plates 108 rotate in the direction close to the partition plate 105. When the strip push plate 124 causes the cabinet door 102 to rotate outward to the maximum angle, the upper surfaces of the strip support plates 108 contact the lower surfaces of the partition plate 105, that is, the strip support plates 108 are retracted.

The inner hexagonal circular plate 104 and the auxiliary shaft 110 are fixedly connected. The axes of the inner hexagonal circular plate 104 and the auxiliary shaft 110 are on the same straight line. The inner hexagonal circular plate 104 is located on the outside of the shell 101. There is friction between the inner hexagonal circular plate 104 and the shell 101. Under the action of the friction between the inner hexagonal circular plate 104 and the shell 101, the inner hexagonal circular plate 104 is prevented from loosening easily. A gear box 111 is provided between the auxiliary shaft 110 and the driving circular plate 137. The gear box 111 is fixedly mounted on the partition plate 105.

The two transmission bevel gears are fixedly connected to the auxiliary shaft 110 and the driving circular plate 137 respectively.

[0052] The rotating rod that cooperates with the inner hexagonal circular plate 104 is engaged with the inner hexagonal circular plate 104, and then the rotating rod is manually rotated, the inner hexagonal circular plate 104 and the auxiliary shaft 110 rotate synchronously, and under the action of the gear box 111, the driving plate 137 rotates, thereby realizing manual control of the opening and closing of the cabinet door 102.

[0053] Working principle: The temperature inside the shell 101 is monitored by the temperature sensor 139, thereby controlling the temperature regulator 109 to adjust the temperature inside the shell 101.

[0054] When it is necessary to inspect and maintain the electrical components 107 inside the housing 101, the unfolding motor 140 is started to control the forward and reverse rotation of the drive plate 137 according to the cabinet door 102 to be opened, thereby controlling the required drive gear 1 132 or drive gear 2 133 to rotate. Under the action of the drive gear 1 132 or drive gear 2 133, the self-locking unit first releases the lock of the cabinet door 102 on that side, that is, the fan-shaped strip 112 on that side is disengaged from the limit strip 113, and the drive plate 137 continues to rotate. , so that the unfolding unit pushes the cabinet door 102 on that side outward, that is, the strip push plate 124 on that side pushes the corresponding cabinet door 102 outward, that is, the cabinet door 102 on that side is opened. While the driving gear 132 or the driving gear 2 133 rotates, under the action of the transmission group 2, the corresponding diamond-shaped rotating block 122 rotates synchronously, that is, the two strip support plates 108 on this side rotate synchronously, that is, when the cabinet door 102 is fully opened, the strip support plate 108 on this side is in a fully retracted state.

[0055] The cabinet door 102 can be opened manually by manually rotating the hexagonal circular plate 104 under the action of the auxiliary shaft 110 and the gear box 111.

[0056] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
