Detailed Description

The principles and features of the present utility model are described below with reference to fig. 1 through 6, the examples being provided for illustration only and not for limitation of the scope of the utility model.

An intelligent well lid with an unlocking key comprises a fixed frame 1, a cover body 4, a locking rod 5, a cam 7, a coded lock 8 and a central shaft 6.

The fixed frame 1 is fixed in the roadbed, a through hole 2 is arranged in the fixed frame 1, and a circle of locking flange 3 is arranged around the side wall of the through hole 2. The locking flange 3 divides the through hole 2 into an upper chamber and a lower chamber.

The cover 4 is arranged in the upper chamber of the through hole 2. The center of the cover 4 is provided with a through guide hole 15, and the center shaft 6 is rotatably connected to the guide hole 15. The central shaft 6 is connected with a coded lock 8, and when a lock tongue of the coded lock 8 extends into a locking hole 9 of the cover body 4, the central shaft 6 and the cover body 4 can rotate oppositely; after the lock tongue of the coded lock 8 is retracted, the central shaft 6 and the cover body 4 can rotate relatively. The bottom of the cover body 4 is provided with a flange plate 10, and the flange plate 10 extends into the lower chamber of the through hole 2. Each locking lever 5 corresponds to two flange plates 10, and the locking lever 5 is slidably connected with the flange plates 10. The bottom of the central shaft 6 is connected with a cam 7, and one end of the locking rod 5 is abutted against the cam 7. The cam 7 rotates with the central shaft 6, and allows one end of the locking lever 5 to slide to the bottom of the locking flange 3. When one end of the locking rod 5 slides to the bottom of the locking flange 3, the fixed frame 1 and the cover body 4 are relatively fixed, and locking is realized in a non-separable way; when one end of the locking lever 5 is retracted, the fixing frame 1 and the cover 4 are separated from each other.

Specifically, the guide hole 15 is divided into a first hole portion 17, a second hole portion 18, a third hole portion 19, and a fourth hole portion 20 in this order from top to bottom. The top of the guide hole 15 is connected with a cover plate 16. The lock body of the coded lock 8 is arranged in the first hole part 17, the lock tongue of the coded lock 8 is arranged in the second hole part 18, the side wall of the second hole part 18 is provided with a locking hole 9, the lock tongue of the coded lock 8 is opposite to the locking hole 9, and the lock tongue of the coded lock 8 can extend into the locking hole 9. The fourth hole portion 20 is provided with a boss 21. The cam 7 is provided with four convex parts 13 and four concave parts 14 at intervals, and the convex parts 13 and the concave parts 14 form a group and correspond to the locking rods 5 one by one. The locking rod 5 is provided with a skirt 11, the skirt 11 is arranged between the two flange plates 10, the locking rod 5 is sleeved with a spring 12, and the spring 12 is arranged between the skirt 11 and the flange plates 10. The locking lever 5 has a sliding tendency towards the cam 7 under the action of the spring 12. When the cam 7 rotates to bring the lock lever 5 into abutment with the recess 14, the lock lever 5 is retracted; when the cam 7 rotates to bring the lock lever 5 into abutment with the boss 13, the lock lever 5 protrudes.

In order to facilitate the rotation of the central shaft 6, a profiled section 22 for the rotation of the drive is provided on the top surface of said central shaft 6.

The locking principle of the device is as follows: the central shaft 6 is rotated, the convex part 13 of the cam 7 is abutted with the locking rod 5, one end of the locking rod 5 slides to the lower part of the locking flange 3, then the coded lock 8 is started, the lock tongue of the coded lock 8 extends into the locking hole 9, the central shaft 6 and the cam 7 are not rotatable, and the fixed frame 1 and the cover body 4 are locked; when the cover 4 needs to be opened, the coded lock 8 is closed, the lock tongue of the coded lock 8 is retracted, the central shaft 6 is rotated, the concave part 14 of the cam 7 is opposite to the locking rod 5, the locking rod 5 is retracted, and the fixed frame 1 and the cover 4 can be separated relatively.
