DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1

[0021] The present invention provides an intelligent power switch cabinet, such as Figures 1 to 7 As shown, it includes a cabinet body 1, a cabinet door 3 is hinged on the front side of the cabinet body 1, a fan-shaped gear 4 is fixedly installed at the rear position of the bottom end of one side of the cabinet door 3, a rack 5 is slidably installed on the bottom end of the interior of the cabinet body 1, the outer surface of the rack 5 and the outer surface of the gear are meshed with each other, slide rail structures 6 are fixedly installed on both sides of the bottom end of the interior of the cabinet body 1, the same fixed plate 7 is slidably connected between the two slide rail structures 6, a slider 8 is slidably installed on the back of the fixed plate 7, a rotating shaft 9 is fixedly installed on the bottom end of the interior of the cabinet body 1, a connecting rod 10 is rotatably installed on the outer surface of the rotating shaft 9, a transmission shaft 29 is rotatably installed on one end of the connecting rod 10, and the top of the transmission shaft 29 is rotatably installed on the bottom end of the slider 8, a hinge support 11 is fixedly installed on one side of the outer surface of the connecting rod 10, a transmission rod 12 is rotatably installed inside the hinge support 11, and one end of the transmission rod 12 is rotatably connected to one end of the rack 5.

[0022] like Figure 4 and Figure 5As shown, a guide plate 13 is fixedly installed at the edge of one side of the fixed plate 7, a venturi tube 14 is fixedly installed on the inner wall of one side of the cabinet 1, one end of the venturi tube 14 is fixedly connected with a sleeve 15, the sleeve 15 is fixedly installed on the inner wall of one side of the cabinet 1, a heat dissipation hole is opened at the position where the sleeve 15 and the inner wall of the cabinet 1 are in contact, a filter screen 28 is fixedly installed inside the heat dissipation hole, a piston 16 is slidably installed inside the sleeve 15, a plug rod 17 is fixedly installed on the rear side of the piston 16, a crank connecting rod 18 is rotatably installed on the inner wall of one side of the cabinet 1, one end of the crank connecting rod 18 is slidably installed inside the guide plate 13, and one end of the plug rod 17 is slidably installed on the crank connecting rod The other end of the rod 18 moves outside the cabinet 1 through the fixing plate 7, driving the guide plate 13 to move, so that the guide plate 13 pushes the crank connecting rod 18 to rotate, so that the other end of the crank connecting rod 18 pulls the plug rod 17. Since the top height of the crank connecting rod 18 keeps changing when the crank connecting rod 18 rotates, one end of the crank connecting rod 18 slides along one end of the plug rod 17. When the plug rod 17 is pulled, the air pressure inside the sleeve 15 decreases, so that the hot air is sucked into the sleeve 15 through the venturi tube 14. The filter 28 prevents external dust from entering the sleeve 15. At the same time, the air sucked into the sleeve 15 through the venturi tube 14 will flow out from the heat dissipation holes.

[0023] like Figure 2 and Figure 7 As shown, a mounting seat 19 is fixedly installed at the bottom end of the fixed plate 7, a latch rod 2 is slidably installed inside the mounting seat 19, the outer surface of the latch rod 2 is located at the inner position of the mounting seat 19 and is movably sleeved with a spring 230, a latch sleeve 20 is fixedly installed at the bottom end of the cabinet 1, a connecting rod 21 is rotatably installed at the bottom end of the cabinet 1, one end of the connecting rod 21 is located between the latch rod 2 and the latch sleeve 20, a push plate 22 is fixedly installed at the other end of the connecting rod 21, a spring 23 is fixedly installed at one end of the push plate 22, and one end of the spring 23 is fixedly connected to a fixed seat 24 The fixing seat 24 is fixedly installed at the bottom end of the cabinet 1. When the fixing plate 7 moves to the other end of the slide rail structure 6, the latch rod 2 is squeezed by the outer surface of the latch sleeve 20, and the spring 2 elastically contracts, so that the latch rod 2 slides in the mounting seat 19. When the fixing plate 7 drives the latch rod 2 to move to the middle position of the latch sleeve 20, the spring 2 30 loses its extrusion elasticity and recovers, so that the spring 2 pushes the latch rod 2 to slide into the latch sleeve 20, so that the fixing plate 7 cannot retract, thereby ensuring that the fixing plate is in a stable position so that the staff can stably inspect and repair the equipment.

[0024] like Figure 2 and Figure 3 As shown, an arc track 25 is fixedly installed at the bottom end of the cabinet 1, and a transmission shaft 29 is slidably installed inside the arc track 25. The transmission shaft 29 slides in the arc track 25, so that the transmission shaft 29 pushes the fixed plate 7 to slide through the slider 8, which makes the process more stable.

[0025] like Figure 4 and Figure 5 As shown, a valve 26 is installed at the throat of the venturi tube 14 to prevent dust in the air from entering the interior of the sleeve 15 , thereby avoiding wear between the interior of the sleeve 15 and the piston 16 and extending the service life of the piston 16 .

[0026] like Figure 2 and Figure 3 As shown, a guide groove is provided inside the rack 5, and two guide posts 27 are provided inside the guide groove. Both guide posts 27 are fixedly installed at the bottom end of the cabinet 1. The guide posts 27 limit the rack 5 so that the rack 5 can slide stably.

[0027] like Figure 2 and Figure 7 As shown, one end of the latch rod 2 is an inclined surface, and the horizontal distance between the inclined surface and the other end of the latch rod gradually decreases toward the direction of the push plate 22. The inclined surface can play a guiding role, guiding the latch rod 2 to accurately enter the interior of the latch sleeve without manual insertion, so that the latch rod 2 and the latch sleeve 20 are locked, thereby making it impossible for the fixed plate 7 to retract.

[0028] like Figure 2 and Figure 4 As shown, a slide groove is provided inside one end of the crank connecting rod 18, and a fixed shaft is fixedly installed at one end of the plug rod 17. The fixed shaft is slidably installed inside the slide groove. The cooperation between the slide groove and the fixed shaft enables the plug rod 17 to perform reciprocating linear motion under the drive of the crank connecting rod 18.

[0029] like Figure 3 and Figure 4 As shown, a mounting groove is provided at the bottom of the slider 8, and the top of the transmission shaft 29 is rotatably mounted inside the mounting groove. The mounting groove provides a rotation space for the transmission shaft 29, so that the transmission shaft 29 can better drive the slider 8 to move.

[0030] Working principle: when the staff opens the cabinet door 3, the sector gear 4 is driven to rotate. During the rotation of the sector gear 4, the rack 5 is driven to move. Then the rack 5 pulls the connecting rod 10 through the transmission rod 12 to rotate with the rotating shaft 9 as the center point, thereby driving the transmission shaft 29 to move. During the movement of the transmission shaft 29, the slider 8 will be pulled to move. Since the slider 8 slides in the fixed plate 7, the slider 8 continuously pushes the fixed plate 7 to slide forward along the slide rail structure 6. During the movement of the fixed plate 7, the fixed plate 7 drives the guide plate 13 to move, so that the guide plate 13 pushes the crank connecting rod 18 to rotate, so that the other end of the crank connecting rod 18 pulls the plug rod 17. When the plug rod 17 is pulled, the internal air pressure of the sleeve 15 is reduced, so that the hot air flow pushed by the movement of the fixed plate 7 is sucked into the sleeve 15 through the venturi tube 14. When the piston 16 moves to the heat dissipation hole position, the hot air sucked into the sleeve 15 can flow out through the heat dissipation holes. When the fixed plate 7 slides to the other end of the slide rail structure 6, the plug rod 17 is pulled. When the bolt rod 2 is pushed back to the middle of the bolt sleeve 20, the spring 2 will recover and push the bolt rod 2 to return to its original position, so that the bolt rod 2 can be used again next time.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
