Detailed Description

The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.

As shown in fig. 1 to 5, an automatic opening and closing lifting platform of an outlet comprises a mounting frame 1, wherein four screws 2 distributed in square are arranged at the lower end of the mounting frame 1 through bearings, the four screws 2 are jointly connected with a driving mechanism 3, screw sleeves 4 are respectively arranged on the screws 2, and a center stage 5 is jointly arranged on the four screw sleeves 4.

The outside of swivel nut 4 all is fixed with and is a rack 6 of vertical distribution, a rack 6 all meshes with driving gear 7, driving gear 7 all is connected with the connecting axle 8 of installing on mounting bracket 1.

The installation frame 1 is provided with two baffle plates 9 which are in symmetrical distribution in a horizontal sliding fit manner on the same vertical plane, the two baffle plates 9 are in staggered distribution on the same horizontal plane, the baffle plates 9 are hinged with a movable plate 10 which is in sliding fit with the connecting shaft 8, a second rack 11 is fixed on the end face of the movable plate 10 far away from the screw sleeve 4, and the second rack 11 is meshed with a pinion 12 arranged on the connecting shaft 8. Rectangular through holes 1a for the center stage 5 to enter and exit are formed in the top of the mounting frame 1. When the movable plate 10 is used, the movable plate 10 is driven to move and drag the baffle plates 9 to start and close the rectangular through hole 1a of the mounting frame 1, so that the up-and-down movement of the screw sleeve 4 is converted into the oblique movement of the baffle plates 9 through the power transmission of the racks and the gears, the high efficiency of movement is realized, and the two baffle plates 9 distributed in a staggered manner avoid the movement interference on the vertical surface.
