Abstract

A locking mechanism for a tank body and a tank cover of a pressure tank. The locking mechanism includes: a tank body, a tank chamber, a tank cover, a hydraulic cylinder, a locking ring, a spring cylinder, a fixing supporting mechanism, a fixing plate, a barb, a notch, and a pulling cylinder.

First claim

What is claimed is:

1. A locking mechanism for a tank body and a tank cover of a pressure tank, comprising:
a tank body ( 1 ), a tank chamber ( 2 ), a tank cover ( 3 ), a hydraulic cylinder ( 4 ), a locking ring ( 5 ), a spring cylinder ( 6 ), a fixing supporting mechanism ( 7 ), a fixing plate ( 8 ), a barb ( 9 ), a notch ( 10 ), and a pulling cylinder ( 11 );
wherein the tank chamber ( 2 ) is in the tank body ( 1 ), the tank body ( 1 ) is provided thereon with the tank cover ( 3 ) and is provided on its left side with the hydraulic cylinder ( 4 ), the hydraulic cylinder ( 4 ) is provided on its lower side with the locking ring ( 5 ), the locking ring ( 5 ) is provided on its lower side with the spring cylinder ( 6 ), the spring cylinder ( 6 ) is provided on its right side with the fixing supporting mechanism ( 7 ), the tank body ( 1 ) is provided thereon with the fixing plate ( 8 ), the fixing plate ( 8 ) is provided on its lower side with the barb ( 9 ), the locking ring ( 5 ) is provided on its lower side with the notch ( 10 ), and the spring cylinder ( 6 ) is provided at its vicinity with the pulling cylinder ( 11 ).

2. The locking mechanism for a tank body and a tank cover of a pressure tank according to claim 1 , wherein eight barbs ( 9 ) are distributed uniformly along a circumferential direction of the tank cover ( 3 ).

3. The locking mechanism for a tank body and a tank cover of a pressure tank according to claim 1 , wherein three spring cylinders ( 6 ) are distributed uniformly along a circumferential direction of the tank body ( 1 ).

4. The locking mechanism for a tank body and a tank cover of a pressure tank according to claim 2 , wherein the spring cylinder ( 6 ) supports one locking ring ( 5 ), and each of the spring cylinders ( 6 ) is provided at its vicinity with one pulling cylinder ( 11 ).

5. The locking mechanism for a tank body and a tank cover of a pressure tank according to claim 2 , wherein eight pressing hydraulic cylinders ( 4 ) are distributed uniformly above the locking ring ( 5 ), and eight notches are distributed uniformly on the locking ring.
