[0036] With reference to Figure 2 , Figure 3 and Figure 5 The inner part of the upper mounting plate 2 and the lower mounting plate 7 is provided with an auxiliary mounting assembly 5, the auxiliary mounting assembly 5 needs to be taken out after the installation of the upper mounting plate 2 and the lower mounting plate 7 is completed, the auxiliary mounting assembly 5 includes a control rod 51, the inner wall of the control rod 51 is provided with a movable groove 52, the movable groove 52 is provided in the middle part of the control rod 51, the inner wall of the movable groove 52 is slidably connected with a sliding sheet 53, the outer wall of the sliding sheet 53 and the inner wall of the movable groove 52 are elastically connected through a spring 54, one end of the spring 54 is fixedly connected with the outer wall of the sliding sheet 53, the other end of the spring 54 is fixedly connected with the inner wall of the movable groove 52, the elastic force of the spring 54 is greater than the torsion of the torsion spring 43, the inner wall of the sliding sheet 53 penetrates and is fixedly connected with a pull rod 55, the outer wall of the pull rod 55 penetrates the inner wall of the control rod 51, the outer wall of the pull rod 55 is hingedly connected with a connecting rod 56, one end of the connecting rod 56 away from the pull rod 55 is hingedly connected with a fixed rod 57, the length of the fixed rod 57 is shorter than the difference between the depth of the positioning groove 8 and the length of the moving rod 9, through the length setting of the fixed rod 57, it is ensured that when the fixed rod 57 completely enters the positioning groove 8, there is still a part of the hole position outside the positioning groove 8, so as to ensure that the plug rod 45 can enter the positioning groove 8 when the fixed rod 57 is in the internal state of the positioning groove 8, the outer wall of the fixed rod 57 penetrates and is slidably connected with the inner wall of the control rod 51.

[0037] With reference to Figure 2 - Figure 3The upper and lower ends of the shell 1 are detachably connected with end covers 6, and the upper and lower end covers 6 are respectively provided with interfaces connected with water pipes, and the specific connection relationship between the end cover 6 and the water pipe is related to the operation of realizing water purification, positive washing and reverse washing, and the specific operation mode is the prior art, which can be realized by the person skilled in the art, so in this case, it is not described too much, and the upper and lower ends of the shell 1 and the outer wall of the end cover 6 are detachably connected through a clamp.

[0038] Working principle: when using, the worker installs the upper mounting plate 2 and the lower mounting plate 7 on the control rod 51, first, the upper mounting plate 2 and the lower mounting plate 7 are sleeved outside the control rod 51, then the pull rod 55 is pulled, so that the pull rod 55 drives the end connected with the connecting rod 56 to move, so that the connecting rod 56 becomes inclined, so that the projection length of the connecting rod 56 in the same direction as the moving direction of the fixed rod 57 becomes shorter, so that the fixed rod 57 moves towards the inside.

[0039] At this time, the upper mounting plate 2 and the lower mounting plate 7 are adjusted to the position where the positioning groove 8 and the fixed rod 57 are in the same horizontal area, then the worker releases the pull rod 55, and rotates the control rod 51, when the control rod 51 is rotated to make the fixed rod 57 enter the internal area of the positioning groove 8, the sliding sheet 53 is reset under the elastic force of the spring 54, so that the pull rod 55 is reset.

[0040] When the pull rod 55 is reset, the connecting rod 56 returns to the position in the same direction as the sliding direction of the fixed rod 57, so at this time the fixed rod 57 enters the positioning groove 8, so that the control rod 51, the upper mounting plate 2 and the lower mounting plate 7 are fixed as a whole.

[0041] At this time, the worker puts the whole of the upper mounting plate 2, the lower mounting plate 7, the membrane wire 3, the control rod 51 and the internal structure into the appropriate position of the shell 1, because there is support of the control rod 51 between the upper mounting plate 2 and the lower mounting plate 7 at this time, so it will not be inconvenient to put in due to the wrinkles of the membrane wire 3 when putting in.

[0042] When putting in, the worker first pulls the pull rope 46, and after pulling out the pull rope 46, the pull-out state of the pull rope 46 is limited by the rope buckle 47, when the pull rope 46 is subjected to tension, the pull rope 46 drives the turntable 42 to rotate away from the side of the hole through which the pull rope 46 passes on the outer wall of the shell 1 towards the hole direction, so that the turntable 42 controls the groove 44 to push the control rod 51 in the process of rotating, so that the control rod 51 moves towards the direction of entering the rotating groove 41 under the driving of the control groove 44.

[0043] When the control rod 51, the upper mounting plate 2 and the lower mounting plate 7 are all placed in the proper positions, the worker loosens the pull rope 46 through the rope buckle 47, so that the rotating disc 42 is not under the pulling force, at this time, the worker rotates the control rod 51, when it is rotated to the position where the positioning groove 8 and the insertion rod 45 are engaged, the rotating disc 42 is rotated under the driving of the torsion spring 43, so that the control groove 44 drives the insertion rod 45 to reset, so that the insertion rod 45 enters the positioning groove 8 to limit the upper mounting plate 2 and the lower mounting plate 7.

[0044] Subsequently, the worker pulls the pull rod 55, so that the control rod 51 can be taken out after the fixing rod 57 is pulled out of the positioning groove 8, and the equipment can be used after the end cover 6 is installed, when the equipment needs to be disassembled, the worker first removes the end cover 6, then fixes the control rod 51, the upper mounting plate 2 and the lower mounting plate 7 in the above manner, then releases the fixing relationship between the insertion rod 45 and the upper mounting plate 2 and the lower mounting plate 7, and then the equipment can be taken out.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
