The present invention will be further described and illustrated with reference to the following drawings.

Fig. 1 is an overall structural schematic diagram of a preferred embodiment of the present invention.

Fig. 2 is a schematic view of the structure of the driving member.

1. A first drive ring; 2. a support bar; 3. a second drive ring; 4. a thread block; 5. a drive member; 6. a housing; 7. a drive block; 8. a screw; 9. a nut; 10. a linkage plate.

Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1, the electric distribution box with an elevation device according to the preferred embodiment of the present invention comprises a box body, and the bottom of the box body is provided with a first driving ring 1, a support rod 2, a second driving ring 3, a thread block 4 and a driving member 5.

Wherein the top of the support rod 2 can move longitudinally relative to the box body, a part of the top of the support rod 2 is arranged in the box body, the number of the first drive rings 1 is four, each first drive ring 1 is fixed at one of four corners of the bottom of the box body, the longitudinal section of each first drive ring 1 is in an I shape, the support rod 2 passes through the axis of the first drive ring 1, the support rod 2 slides longitudinally along the first drive ring 1, the second drive ring 3 is arranged at the lower side of the first drive ring 1, and the support rod 2 can also slide longitudinally relative to the second drive ring 3. The screw block 4 is fixed on the support rod 2, the screw block 4 is arranged between the first drive ring 1 and the second drive ring 3, the longitudinal section of the driving piece 5 is cylindrical, the inner side of the driving piece 5 is in threaded connection with the screw block 4, the driving piece 5 can horizontally rotate relative to the first drive ring 1 and the second drive ring 3, and the rotation axis is consistent with the axis of the support rod. The drive 5 serves to limit the longitudinal movement of the second drive ring 3.

The driver 5 comprises a housing 6 and a drive block 7, the drive block 7 being mounted on an inner wall of the housing 6.

The transverse section of the driving block 7 is semicircular, a screw 8 is inserted in the radial direction of the driving block 7, the screw 8 penetrates through one side of the driving block 7 and the shell 6, nuts 9 are connected to two ends of the screw 8 in a threaded manner, a nut 9 groove is concavely arranged on one side, close to the thread block 4, of the driving block 7 and used for placing the nut 9 on one side of the screw 8, and the other nut 9 is abutted to the outer surface of the shell 6.
