[0007] According to the above technical solution, a first spring is arranged between the sliding rod and the control cabinet, and the sliding rod is driven to reset by the first spring. A second spring is arranged between the sliding frame and the control cabinet, and the sliding frame is driven to reset by the second spring.

[0008] According to the above technical solution, a limiting device for preventing the explosion-proof energy-saving lamp from detaching and a supporting device for supporting the explosion-proof energy-saving lamp are arranged on the connecting seat. The limiting device includes an arc-shaped slider, a fixing plate, a rotating shaft and a short board. The upward movement of the explosion-proof energy-saving lamp drives the fixed seat to move upward. During the upward movement of the fixed seat, it will contact the arc-shaped slider, and the fixed seat will push the arc-shaped slider to move away from the fixed seat. The arc-shaped slider is slidably installed on the inner wall of the connecting seat. The fixing plate is fixedly installed on the surface of the arc-shaped slider.

[0014] The present invention provides an explosion-proof high-voltage switch cabinet energy-saving lighting device that is convenient for loading and unloading. It has the following beneficial effects:

[0015] (1) In this invention, the movement of the sliding frame towards the connecting seat drives the short rod to move towards the connecting seat. The movement of the short rod towards the connecting seat drives the explosion-proof housing to move towards the connecting seat. The explosion-proof housing protects the surroundings of the explosion-proof energy-saving lamp, improving the protection effect on the explosion-proof energy-saving lamp. At the same time, when the explosion-proof energy-saving lamp moves up to the top, by rotating the explosion-proof energy-saving lamp, the rotation of the explosion-proof energy-saving lamp drives the rotation of the fixed seat, the rotation of the fixed seat drives the rotation of the interface, and the interface rotates into the socket. The explosion-proof energy-saving lamp is powered on by being connected to the socket, and normal lighting can be achieved when the revolving door needs to be opened for maintenance.

[0016] (2) In this invention, when the arc-shaped slider moves away from the fixed seat, it will push the fixed plate to move away from the fixed seat. When the fixed plate moves away from the fixed seat, it will push the short board to rotate upward. When the short board disengages from the fixed plate, the first torsion spring will drive the rotating shaft to reset. When the rotating shaft resets, it will drive the connecting plate to reset. The reset of the connecting plate will be limited by the L-shaped sliding plate. By limiting the fixed plate, it is prevented that the arc-shaped slider jams the fixed seat during installation, affecting the installation of the explosion-proof energy-saving lamp. At the same time, when the arc-shaped slider resets, it blocks the fixed seat, preventing the explosion-proof energy-saving lamp from falling directly when the explosion-proof energy-saving lamp is disassembled, resulting in damage to the explosion-proof energy-saving lamp and affecting normal use.

[0017] (3) In this invention, when the trapezoidal slider moves away from the square block, it will drive the arc-shaped plate to contact the explosion-proof energy-saving lamp. The arc-shaped plate supports the explosion-proof energy-saving lamp to prevent the explosion-proof energy-saving lamp from losing contact due to vibration or shaking, affecting the normal use of the explosion-proof energy-saving lamp. At the same time, when the long board moves away from the square block, it will drive the clamping plate to move away from the square block. By moving the clamping plate away from the square block and clamping it into the card slot, the sliding rod is limited by the clamping plate. By limiting the sliding rod, it is prevented that the explosion-proof housing is opened, improving the protection effect on the explosion-proof energy-saving lamp. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shaft 143 is rotatably installed on the surface of the connecting seat 4. The short plate 144 is fixedly installed on the surface of the rotating shaft 143. By limiting the fixing plate 142, it is prevented that the arc-shaped slider 141 jams the fixed seat 11 during installation, affecting the installation of the explosion-proof energy-saving lamp 41.

[0031] An arc-shaped slide plate 145 is slidably installed on the surface of the connecting seat 4. An L-shaped frame 146 is fixedly installed on the surface of the arc-shaped slide plate 145. A connecting plate 147 is fixedly installed on the surface of the rotating shaft 143. An L-shaped slide plate 148 is slidably installed on the surface of the connecting seat 4. A triangular block 149 is fixedly installed on the top of the L-shaped slide plate 148, preventing the explosion-proof energy-saving lamp 41 from directly falling off when the explosion-proof energy-saving lamp 41 is disassembled, resulting in damage to the explosion-proof energy-saving lamp 41 and affecting normal use.

[0032] A third spring is provided between the arc-shaped slider 141 and the connecting seat 4 to drive the arc-shaped slider 141 to reset through the third spring. A first torsion spring is provided between the rotating shaft 143 and the connecting seat 4 to drive the rotating shaft 143 to reset through the first torsion spring. A fourth spring is provided between the connecting seat 4 and the L-shaped slide plate 148 to drive the L-shaped slide plate 148 to reset through the fourth spring.

[0033] The supporting device includes a square block 151, a trapezoidal slider 152 and an arc-shaped plate 153. The square block 151 is fixedly installed at the bottom of the arc-shaped sliding plate 145. The trapezoidal slider 152 is slidably installed on the inner wall of the connecting seat 4. The arc-shaped plate 153 is fixedly installed on the surface of the trapezoidal slider 152. The explosion-proof energy-saving lamp 41 is supported by the arc-shaped plate 153 to prevent the explosion-proof energy-saving lamp 41 from losing contact due to vibration or shaking, affecting the normal use of the explosion-proof energy-saving lamp 41.

[0034] A connecting block 154 is fixedly installed on the surface of the trapezoidal slider 152. A long plate 155 is fixedly installed at the top of the connecting block 154. A clamping plate 156 is fixedly installed on the surface of the long plate 155. A clamping groove 157 is formed on the surface of the sliding rod 5. The sliding rod 5 is limited by the clamping plate 156. By limiting the sliding rod 5, the explosion-proof housing 10 is prevented from being opened, improving the protection effect on the explosion-proof energy-saving lamp 41.

[0035] A fifth spring is arranged between the trapezoidal slider 152 and the connecting seat 4. The trapezoidal slider 152 is driven to reset by the fifth spring, and the clamping plate 156 and the clamping groove 157 are in the same horizontal plane.

[0036] When this embodiment works: the explosion-proof energy-saving lamp 41 moves upward to drive the fixing seat 11 to move upward. During the upward movement of the fixing seat 11, it will contact the arc-shaped slider 141. The fixing seat 11 will push the arc-shaped slider 141 to move away from the fixing seat 11. The arc-shaped slider 141 moving away from the fixing seat 11 will push the fixing plate 142 to move away from the fixing seat 11. The fixing plate 142 moving away from the fixing seat 11 will push the short plate 144 to rotate upward. When the short plate 144 is separated from the fixing plate 142, the first torsion spring will drive the rotating shaft 143 to reset.

The downward movement of the L-shaped frame 146 will push the triangular block 149 to move away from the L-shaped frame 146. The triangular block 149 moving away from the L-shaped frame 146 will drive the L-shaped sliding plate 148 to move away from the connecting plate 147. The L-shaped sliding plate 148 moving away from the connecting plate 147 will release the limit on the connecting plate 147, enabling the arc-shaped slider 141 to reset under the elastic force of the third spring. By the reset of the arc-shaped slider 141, the fixing seat 11 is blocked to prevent the explosion-proof energy-saving lamp 41 from directly falling off when the explosion-proof energy-saving lamp 41 is disassembled, resulting in damage to the explosion-proof energy-saving lamp 41 and affecting normal use.

[0037] The downward movement of the arc-shaped slide plate 145 drives the square block 151 to move downward. The downward movement of the square block 151 will push the trapezoidal slider 152 to move away from the square block 151. The movement of the trapezoidal slider 152 away from the square block 151 will drive the arc-shaped plate 153 to contact the explosion-proof energy-saving lamp 41. The explosion-proof energy-saving lamp 41 is supported by the arc-shaped plate 153 to prevent the explosion-proof energy-saving lamp 41 from losing contact due to vibration or shaking, which affects the normal use of the explosion-proof energy-saving lamp 41. At the same time, the movement of the trapezoidal slider 152 away from the square block 151 will drive the connecting block 154 to move away from the square block 151. The movement of the connecting block 154 away from the square block 151 will drive the long plate 155 to move away from the square block 151. The movement of the long plate 155 away from the square block 151 will drive the clamping plate 156 to move away from the square block 151. The clamping plate 156 moves away from the square block 151 and is inserted into the card slot 157. The sliding rod 5 is limited by the clamping plate 156. By limiting the sliding rod 5, the explosion-proof housing 10 is prevented from being opened, and the protection effect on the explosion-proof energy-saving lamp 41 is improved.
