Japanese patent JP4234938B2 discloses a connection device of a filter for connecting and disconnecting the filter from an external pipe, comprising a fixed member having a plurality of joints on a lower surface thereof for making a sealing connection or disconnection with corresponding pipe fittings of the filter, a movable table having a flange holding portion for holding the filter so that the pipe fittings of the filter are aligned with the joints on the fixed member, a guide mechanism, and an operation lever. The operating lever has one end pivotally connected to the fixed member and the other end having a handle, and further has a slide groove in which a pin fixed to the movable table moves.
The guide mechanism comprises 4 elongated members, the 4 members being divided into two groups of 2, one group being located on each side of the connector device, each two elongated members forming a pivotable connection at a central intersection point and forming an X-shape; the two ends of the 4 slender components are connected with pins, the two side surfaces of the same end of the fixed piece and the movable workbench are respectively provided with a horizontal groove, and the pin connected with one end of the slender components can horizontally move in the horizontal grooves. When the operating rod is pivoted, the pin fixed on the movable workbench moves in the sliding groove on the operating rod, the pin connected to one end part of the slender components moves horizontally in the horizontal groove, and the included angle between the two X-shaped slender components is closed or opened, so that the movable workbench is guided to move upwards or downwards, and a plurality of joints penetrating through the lower surface of the fixing piece can form sealing connection or disconnection with corresponding pipe fittings of the filtering unit.
When the included angle between the two X-shaped slender components is expanded to the maximum, the operating rod performs pivoting movement, when the pin connected to one end part of the slender components completes the maximum horizontal displacement in the horizontal groove, the included angle between the two X-shaped slender components is closest, the horizontal displacement of the pin is converted into the vertical displacement of the movable workbench and the filter through the X-shaped fork, and after the movable workbench and the filter complete the vertical displacement, the joint of the filter just forms reliable sealing with the pipe fitting on the fixed part.
In this connection, it is necessary to convert the pivoting movement of the operating lever into a horizontal movement of the pin, which in turn is converted into a vertical movement of the movable table and the filter. The above-described procedure involves two movements, which requires very precise control of the parameters of the length of the elongated member, the length of the horizontal slot of the fixed part and the length of the horizontal slot on the movable table and the outer diameter of the pin located in the horizontal slot, i.e. higher requirements are placed on the manufacture of the component parts of the connecting device, ensuring precise control of all dimensional parameters, increasing the manufacturing difficulty.
In addition, the guide mechanism has a relatively large number of parts, when assembling, 4 slender components are connected through pins to form 2X-shaped forks, and then the 2X-shaped forks are connected to the fixed part and the movable workbench through pins respectively.

When the drive assembly 4 is rotated about the pivot pin 12 relative to the fixed assembly 1, the upper end of the drive assembly 4 is moved away from the fixed assembly 1, thereby forming an opening 5 between the side of the fixed assembly 1 and the drive assembly 4 for removal and attachment of the filter unit 2. Because the opening 5 is located between one side of the fixed component 1 and the driving component 4, the axial height involved in the whole assembly process is much smaller than the sum of the axial heights of the filter unit 2 and the fixed component 1, that is, the space occupied by the assembly process, especially the space in the axial direction, is reduced, and the assembly device can adapt to a narrower installation environment and has higher installation adaptability.
Further, one of the support assembly 3 and the side plate 14 has a guide projection 31, and the other has a guide groove 13, and the guide projection 31 is slidably inserted into the guide groove 13 to movably connect the support assembly 3 to the side plate 14. In this embodiment, as shown in fig. 1 and 5, 2 guide protrusions 31 are fixed to opposite sides of the outer periphery of the support assembly 3, and each of the two side plates 14 has one guide groove 13, and the 2 guide protrusions 31 are respectively engaged into the guide grooves 13 and can slide relatively. Of course in other embodiments, the guide projection 31 may be located in the side plate 14 and the guide groove 13 provided on the support assembly 3.
As shown in fig. 4, in order to secure stability of the guide projection 31, a limit boss 311 is formed on the guide projection 31, and the limit boss 311 is used to abut against an opening edge of the guide groove 13. After the guide lugs 31 are clamped into the guide grooves 13, the limit bosses 311 are attached to the edges of the openings of the guide grooves 13, so that stable matching of the guide lugs 31 and the guide grooves 13 can be ensured, and the guide lugs 31 are prevented from being separated or offset.
As shown in fig. 1, 3 and 5, the guide groove 13 includes at least a limiting section 131, and the limiting section 131 extends along a direction perpendicular to the axial direction of the filter unit 2, so that when the guide projection 31 and the limiting section 131 slide relatively, the support assembly 3 and the filter unit 2 can be driven to move along the direction perpendicular to the axial direction of the filter unit 2, so that the first joint section 111 and the second joint section 211 form a sealed connection or separation. The length of the limiting section 131 is equal to or greater than the length of the sealing stroke of the first and second engagement sections 111, 211. When the guide projection 31 and the stop segment 131 of the guide groove 13 are slid relative to each other, the support assembly 3 brings the filter unit 2 together into a movement perpendicular to the axial direction of the filter unit 2, so that the axially extending second engagement segment 211 of the tube 21 of the filter unit 2 is in sealing connection or disconnection with the first engagement segment 111 of the fitting 11.
Wherein the sealing stroke of the axially extending second engagement section 211 of the tube 21 of the filter unit 2 with the first engagement section 111 of the joint 11-the process of the sealing connection between the end of the axially extending second engagement section 211 of the tube 21 of the filter unit 2 and the end of the first engagement section 111 of the joint 11 being just aligned to both, the displacement of the tube 21 in the direction perpendicular to the axial direction relative to the movement of the first engagement section 111, while the length of the limiting section 131 extending in the direction perpendicular to the axial direction is not less than the displacement, ensures that the axial height of the filter unit 2 is constant and that the axially extending second engagement section 211 of the tube 21 and the first engagement section 111 of the joint 11 are aligned in the process of the sealing connection between the second engagement section 211 of the tube 21 and the first engagement section 111 of the joint 11 being formed, and that after the installation, a sufficient axial compression of the sealing ring mounted therebetween is formed to form a sealing connection.
In other embodiments, as shown in fig. 8, the guiding slot 13 further includes a guiding section 132 extending obliquely with respect to the axial direction, which is located at a side of the limiting section 131 away from the joint 11. The guide section 132 is provided to reduce the resistance of the guide projection 31 and the guide groove 13 to relative sliding, thereby making the operation of the driving assembly 4 more labor-saving. When the guide projection 31 and the guide section 132 slide relatively, the movement direction of the support member 3 is inclined relative to the axial direction. However, the support assembly 3 and the filter unit 2 are moved in a direction perpendicular to the axis of the filter unit 2 during the sealing stroke in which the first engagement section 111 and the second engagement section 211 form a sealing connection, i.e. the stroke corresponding to the limiting section 131.
As shown in fig. 4 and 5, the driving component 4 is connected with the supporting component 3 through a connecting rod 32, when the driving component 4 performs pivotal motion relative to the side plate 14, the driving component drives the connecting rod 32 to perform pushing action on the supporting component 3 so as to push the guide protruding block 31 and the guide groove 13 to slide relatively, and the supporting component 3 moves towards a direction approaching or separating from the joint 11, so that the overall structure cooperation is stable and effective. Specifically, one end of the connecting rod 32 is connected with the guide projection 31, and a shaft 34 passes through the guide projection 31 and the connecting rod 32 to be connected with the support assembly 3.

The number of driving arms 41 is two, and the two driving sections 411 are connected into a whole by a connecting arm 413. The 2 side plates 14 are respectively attached to the 2 driving arms 41, so that stable rotation between the driving assembly 4 and the fixing assembly 1 is ensured. The guide projection 31 and the guide groove 13 are provided between the two opposite sides of the outer periphery of the support member 3 and the two side plates 14; the connecting arm 413 and the fixing plate 15 are located at opposite sides of the side plate 14. In other words, taking the direction shown in fig. 5 as an example, the connecting arm 413 is located on the right side of the side plate 14, and the fixing plate 15 is located on the left side of the side plate 14. The two driving arms 41 are respectively positioned at two sides of the side plate 14 and are attached to the side plate 14, so that the movable stability of the driving arms 41 is ensured, and the stability of the driving assembly 4 during the pivoting movement relative to the side plate 14 is also ensured.

When the mounting projection 22 is inserted into the mounting groove 33, the filter unit 2 is restrained in the support member 3, i.e., the filter unit 2 does not move up and down and shift left and right. The mounting groove 33 is matched with the mounting lug 22, so that the limit of the filter unit 2 is ensured, the filter unit 2 is prevented from being axially separated from the support component 3, or the filter unit is prevented from being offset left and right relative to the support component 3, and the whole assembly structure is stable.
