DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A theft-proof cover plate for a transformer substation comprises a connecting frame 1, a fixing plate 2 is fixedly mounted on the outer wall of the connecting frame 1, a plurality of fixing holes are opened on the outer wall of the fixing plate 2, two moving frames 3 are fixedly mounted on the outer wall of the two moving frames 3, stud screws 4 are rotatably mounted inside the two moving frames 3, the outer walls of the two stud screws 4 are connected by a transmission mechanism, the transmission mechanism comprises a pulley 5 fixedly mounted on the outer walls of the two stud screws 4, the outer walls of the two pulleys 5 are connected and driven by a belt, a rocker 6 is fixedly mounted on the outer wall of one of the stud screws 4, two moving sleeves 8 are threadedly mounted on the outer walls of the two stud screws 4 through a limiting mechanism, the limiting mechanism comprises a limiting rod 7 fixedly mounted inside the moving frame 3, the limiting rod 7 slides through the two moving sleeves 8, the limiting rod 7 can limit the two moving sleeves 8 so that the two moving sleeves 8 can only move axially along the outer wall of the stud screw 4.

[0023] The outer walls of the two movable sleeves 8 are fixedly installed with a first connecting frame 9, and a connecting plate 10 is rotatably installed inside each first connecting frame 9. The ends of two adjacent connecting plates 10 are rotatably connected to a second connecting frame 11, and the outer walls of the two second connecting frames 11 are fixedly installed with a connecting sleeve 13 through a connecting mechanism. The connecting mechanism includes a connecting plate 12 fixedly installed on the outer wall of the second connecting frame 11, and the end of the connecting sleeve 13 is fixedly connected to the inner wall of the connecting plate 12.

[0024] A connecting rod 14 is slidably installed inside the two connecting sleeves 13, and a fixing pin 15 is slidably installed on the outer wall of the two connecting sleeves 13. The outer wall of the two connecting rods 14 is provided with a plug hole that matches the fixing pin 15. The ends of the two fixing pins 15 are fixedly installed with a shifting block 16. The inner walls of the two shifting blocks 16 are connected to the outer wall of the connecting sleeve 13 on the same side through a fixing mechanism. The fixing mechanism includes a fixing spring 17 installed on the outer wall of the fixing pin 15. The two ends of the fixing spring 17 are respectively connected to the outer wall of the connecting sleeve 13 and the shifting block 16 The inner wall is elastically connected, and the fixing spring 17 can fix the fixing pin 15 to prevent it from detaching from the outer wall of the connecting sleeve 13, thereby ensuring the fixing effect of the connecting rod 14.

[0025] When the utility model is used, the fixing plate 2 is installed through the cooperation of the fixing holes and the fixing bolts, thereby completing the fixed installation of the connecting frame 1. When the cover plate 18 is opened and closed, the rocking wheel 6 can be rotated to drive one of the double-headed screws 4 to rotate. At this time, one of the double-headed screws 4 drives the other double-headed screw 4 to rotate through the two pulleys 5 connected by the belt. Under the cooperation of the pulley 5 and the belt, the two double-headed screws 4 can rotate at the same time. When the double-headed screw 4 rotates, it can drive the two moving sleeves 8 to move through the cooperation of the limit rod 7. When the two moving sleeves 8 move, they can drive the second connecting frame 11 to move through the cooperation of the first connecting frame 9 and the connecting plate 10. Therefore, the second connecting frame 11 can drive the connecting plate 12 to move, and the connecting plate 12 can drive the cover plate 18 to move through the cooperation of the connecting sleeve 13 and the connecting rod 14, thereby completing the convenient opening and closing of the cover plate 18, and under the fixation of the connecting rod 14, the cover plate 18 can be prevented from launching and falling.

When it is necessary to disassemble the cover 18, the shift block 16 can be moved to drive the fixing pin 15 to move out of the socket to release the fixation of the connecting rod 14, and then the connecting rod 14 can be pulled out of the connecting sleeve 13, thereby realizing convenient disassembly of the cover 18.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
