The locking device 104 coupled to the lower surface of the locking device 104 moves along the locking device guide rod 115 attached to the upper surface of the end plate 103 so that the locking device 104 is rotated .

The distance of the locking device guide rods 115 is determined by the number of divisions of the locking device 104 and the distance of the locking device guide rods 115 is determined by the distance between the two locking device guide sockets 116) (Fig. 10).

The locking device guide 114 is inserted first through the locking device guide rod 115 and is then inserted into the lower surface of the locking device 104 by the locking device guide socket 116 attached to the lower surface of the locking device 104. [ Lt; / RTI >

The locking device guide 114 performs a linear movement along the locking device guide rod 115 when the locking device 104 rotates to suppress the rotation of the locking device 104 beyond the allowable rotation angle do.

11 and 12 are views for explaining a state in which a lid of a pressure vessel with an integrated rotary lock lid according to an embodiment of the present invention is completely installed in a pressure vessel.

In order to assemble the integral rotary lock lid according to the embodiment of the present invention into the pressure vessel 100, the end plug 110 is first attached to the hinge 111 (111 ) And fixed with the hinge pin 119, the end plug 117 is mounted the last time.

The size of the handle path 120 attached to the end plug lid 110 can be reduced when the handle 106 is formed as an independent part without integrating the handle 106 into the handle bar 109. [

13A to 13C are views showing a method of removing and attaching the integral type rotary lock cover in a reverse osmosis membrane pressure vessel with an integral rotary lock cover according to an embodiment of the present invention. If in some cases completely rotated in without removing the hinge pin, such as 13a to the handle allows the angle to the left direction, and the lock is released, the lock is to pull the knob in the off state to the outside edges of the pressure vessel pressure, including end plates The lid of the container is removed. When the hinge pin is removed as shown in FIG. 13B, the pressure vessel lid can be removed, and the pressure vessel lid can be completely opened as shown in FIG. 13C.

The pressure vessel lid is then reinstalled in the reverse order of the method described above.
