[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a top plate structure for an intelligent pressure scanning valve, such as... Figure 1-6 As shown, the top plate structure of the intelligent pressure scanning valve includes a top plate body 1. A connecting sleeve 2 is movably installed at the rear end of the top plate body 1. A positioning sleeve 4 is movably installed at the rear end of the connecting sleeve 2. The positioning sleeve 4 is fixedly connected to the pressure scanning valve. Two sets of insert blocks 11 are fixedly installed on the front sides of both the left and right ends of the connecting sleeve 2. Two sets of slots 12 are opened in the rear sides of both the left and right ends of the top plate body 1. The two sets of insert blocks 11 are movably inserted into the two sets of slots 12. Two sets of locking screws 13 are rotatably installed on both the left and right ends of the top plate body 1. The two sets of locking screws 13 are connected to the two sets of insert blocks 11 by threads. A snap-fit ​​component is provided at the connection between the connecting sleeve 2 and the positioning sleeve 4.

[0026] The snap-fit ​​assembly makes the connection between the connecting sleeve 2 and the positioning sleeve 4 more stable and less prone to loosening. The four sets of inserts 11 and four sets of locking screws 13 are connected to fix the connecting sleeve 2 to the top plate body 1. The snap-fit ​​assembly allows the top plate body 1 and the connecting sleeve 2 to be quickly removed from the positioning sleeve 4, making it easy to replace the top plate body 1.

[0027] A sealing sleeve 3 is fixedly installed at the front end of the connecting sleeve 2, and the inner wall of the front end of the sealing sleeve 3 is tightly fitted with the inner wall of the rear end of the top plate body 1.

[0028] By setting the sealing sleeve 3, the top plate body 1 and the connecting sleeve 2 can be limited, preventing the top plate body 1 and the connecting sleeve 2 from moving, and further improving the stability of the top plate structure.

[0029] A sealing ring is glued to the inner wall of the sealing sleeve 3, and the sealing ring on the inner wall of the sealing sleeve 3 is tightly fitted to the outer wall of the top plate body 1.

[0030] The sealing ring further improves the sealing performance between the top plate body 1 and the connecting sleeve 2, effectively preventing gas or liquid from leaking from the gap between the top plate body 1 and the connecting sleeve 2, thus ensuring the normal operation of the equipment.

[0031] The snap-fit ​​assembly includes two sets of slots 5, which are located inside the upper end of the connecting sleeve 2. Two sets of locking blocks 6 are fixedly installed on the rear side of the upper end of the positioning sleeve 4. The two sets of locking blocks 6 are movably inserted into the two sets of slots 5. A first limiting block 7 is fixedly installed on the lower side of the positioning sleeve 4, and a second limiting block 8 is fixedly installed on the lower side of the connecting sleeve 2. A connecting screw 9 is rotatably installed inside the second limiting block 8, and a wing nut 10 is threaded onto the rear end of the connecting screw 9.

[0032] Two sets of locking blocks 6 are inserted into two sets of locking slots 5, and the lower ends of the positioning sleeve 4 and the connecting sleeve 2 are locked together by the first limiting block 7, the second limiting block 8, the connecting screw 9 and the wing nut 10, which enables quick locking between the connecting sleeve 2 and the positioning sleeve 4, improving the assembly efficiency of the top plate body 1 and the connecting sleeve 2.

[0033] The cross-sections of the first limiting block 7 and the second limiting block 8 are both U-shaped, and the rear end of the connecting screw 9 is inserted into the groove at the lower end of the first limiting block 7.

[0034] By setting up the U-shaped first limiting block 7 and second limiting block 8 and the connecting screw 9, the connection efficiency between the connecting sleeve 2 and the positioning sleeve 4 is further improved, avoiding loosening problems caused by vibration and other factors during long-term use.

[0035] The inner walls of the two sets of slots 5 and the cross-sections of the two sets of blocks 6 are all L-shaped, and the rear openings of the two sets of slots 5 are flared.

[0036] The L-shaped slot 5 and the card block 6, along with the flared design, allow the card block 6 to be inserted into the slot 5 more easily, further improving the convenience and practicality of the card-connecting assembly.

[0037] Working principle: In use, first connect the top plate body 1 to the connecting sleeve 2. At this time, four sets of inserts 11 are movably inserted into four sets of slots 12. Then rotate four sets of locking screws 13. The four sets of locking screws 13 and the four sets of inserts 11 are connected by threads, thereby fixing the top plate body 1 to the connecting sleeve 2. Next, fix the positioning sleeve 4 at the rear end of the connecting sleeve 2 to the pressure scanning valve. Then, insert the two sets of locking blocks 6 on the front side of the upper end of the positioning sleeve 4 into the two sets of locking slots 5 on the rear side of the upper end of the connecting sleeve 2, and fit the rear side of the connecting sleeve 2 with the front side of the positioning sleeve 4. Rotate the connecting screw 9. The connecting screw 9 rotates and locks in the first limiting block 7 at the lower end of the positioning sleeve 4 in the second limiting block 8. Twist the wing nut 10 at the rear end of the connecting screw 9 to quickly lock the connecting sleeve 2 and the positioning sleeve 4. At this time, the inner wall of the front end of the sealing sleeve 3 is tightly fitted with the inner wall of the rear end of the top plate body 1.
