Referring to fig. 6, 7 and 8, the present embodiment further includes a mounting bracket. The mounting bracket is used to mount a reverse osmosis filter 64 (a generic name for a first reverse osmosis filter and a second reverse osmosis filter). The reverse osmosis filter is cylindrical. The mounting bracket comprises a bracket 65, a first horizontal hinge shaft 66, an outer vertical frame 67, a base 68, an inner vertical frame 69 with the lower end connected to the base, and a suspension frame 70 connected to the upper end of the inner vertical frame. The outer vertical frame comprises a plurality of segments 71 distributed along the up-down direction, specifically 4 segments. The first horizontal hinge shaft is perpendicular to the distribution direction of the inner vertical frame and the outer vertical frame, adjacent sections are connected together through the first horizontal hinge shaft, the upper end of the section positioned at the uppermost part is hinged with the suspension frame through the first horizontal hinge shaft, and the lower end of the section positioned at the lowermost part is hinged with the base through the first horizontal hinge shaft. The first horizontal hinge shaft at the top and the other first horizontal hinge shafts and the segments are connected together in a pluggable manner. The inner vertical frame is provided with a plurality of horizontal suspension rods 72 which are distributed along the vertical direction, specifically 4. The upper end of the segments is provided with a suspension block 73. The suspension block is positioned on one side of a vertical plane 74 passing through the first horizontal hinge shaft, which is far away from the inner vertical frame, and the structure has the advantages that: when the suspension block abuts against the suspension rod, the situation that the plugging below the disconnected section does not fall, namely the falling distance is 0, and the distance of the suspension rod outputting the suspension block to the side where the outer vertical frame is located is minimized so as to improve the structural compactness can be ensured, and the disconnected section can rotate by taking the first horizontal hinge shaft at the upper end of the section as a shaft to generate avoidance. The hanging blocks on the 4 segments are correspondingly positioned on the hanging rods. A stop block 99 is arranged at one end of the suspension rod far away from the inner vertical frame. A bracket 65 is arranged on one side of the lower end of each segment away from the inner vertical frame. One side of the inner vertical frame facing the outer vertical frame is provided with 4 brackets distributed along the vertical direction, and the brackets on the inner vertical frame are blocked by sections in a one-to-one correspondence manner. A stop bracket 93 is arranged on one end of the bracket connected with the inner vertical frame far away from the inner vertical frame and one end of the bracket connected with the subsection far away from the subsection. The lower end of the blocking frame is hinged with the bracket through a second horizontal hinge shaft 75. The second horizontal hinge shaft is parallel to the first horizontal hinge shaft. The lower end of the blocking frame is provided with a poking frame 76 positioned on the bracket. The bracket is provided with a limiting block 77. The shifting frame and the blocking frame generate torque which takes the second horizontal hinge shaft as a shaft to drive the shifting frame to rotate to be overlapped on the limiting block. The bracket is provided with a latch hole 78. The blocking frame is provided with a vertical sliding sleeve 79 and a horizontal sliding sleeve 80. The vertical bolt 81 is inserted in the vertical sliding sleeve. The transverse driving rod 82 is arranged in the transverse sliding sleeve in a penetrating way. The upper end of the vertical bolt is provided with a guide inclined surface 83 for guiding the vertical bolt to move downwards, one end of the transverse driving rod is abutted against the guide inclined surface, and the other end of the transverse driving rod extends out of a blocking surface (i.e. a surface for blocking objects when in use) of the blocking frame and then is connected with the trigger plate 84. The poking frame is connected with the limiting block in an abutting mode, the trigger plate is in a free state, and the lower end of the vertical bolt is aligned with the bolt hole and located outside the bolt hole when the trigger plate is not extruded. When the trigger plate moves to the blocking frame towards the blocking frame to contact an object (a reverse osmosis filter) placed on the bracket, the transverse driving pin drives the lower end of the vertical bolt to be inserted into the bolt hole; that is to say when reverse osmosis filter on the bracket moves towards keeping off the frame and meeting line extrusion trigger plate, trigger the board and pass through the perpendicular bolt of horizontal actuating lever drive and move down, when removing with the butt contact, the perpendicular bolt inserts that the downthehole receipt of bolt keeps off the frame can not be promoted and produce and rotate and lose the blocking effect. And a pin releasing spring 85 for driving the vertical pin to be pulled out of the pin hole is arranged in the pin hole, so that the vertical pin can be actively pulled out without interfering the rotation of the blocking frame when the reverse osmosis filter loses the pressing action on the trigger plate. The blocking frame rotates to the shifting frame through the second horizontal hinge shaft, the reverse osmosis filter supported on the bracket contacts the blocking frame, and the reverse osmosis filter is driven to contact the trigger plate. The holding surface 86 of the bracket is a ramp. The support surfaces of the brackets connected to the inner vertical frame are inclined toward the inner vertical frame, and the support surfaces of the brackets arranged on the segments are inclined toward the segments.
In use, a reverse osmosis filter is placed on each bracket to achieve a two-row installation of reverse osmosis filters. When the reverse osmosis filter on the front side vertical frame is taken, the reverse osmosis filter is disconnected with the joint of the gas pipeline, and then the reverse osmosis filter is taken down from the bracket. The procedure for removing the reverse osmosis filter from each bracket on the inner vertical shelf is the same, except for the different sections that need to be avoided, and now the reverse osmosis filter on the second bracket 87 from the top on the side vertical shelf is taken as an example as follows: the third horizontal pivot shaft 88 from the top is pulled out so that the second section 89 from the top is disconnected from the third section 90, and the third section and the fourth section 91 are suspended from the third suspension rod 94 by the suspension block 92 on the third section. And the second section is rotated by taking the second first horizontal hinge shaft 95 as an axis towards the direction far away from the inner vertical frame to avoid, so that a taking-out space is generated, and then the reverse osmosis filter on the second bracket is taken down.
Referring to fig. 8, the process of removing the reverse osmosis filter from the bracket is: the handle 98 on the blocking frame is grasped to drive the blocking frame to rotate the bracket towards the direction far away from the upper surface of the bracket by taking the second horizontal hinge shaft as the shaft, namely the direction C in the drawing, when the bracket rotates, the shifting frame and the vertical bolt synchronously rotate, the reverse osmosis filter on the shifting frame enables the reverse osmosis filter to rotate towards the blocking frame and is transferred to the blocked frame to be supported, and then the reverse osmosis filter rolling over on the blocking frame is caught and is transferred.
The second embodiment is the same as the first embodiment in that:
referring to fig. 9, the bracket is further provided with an arc-shaped avoidance slot 96 for inserting a vertical bolt, which takes the second horizontal hinge shaft as a center line. The blocking frame rotates to the shifting frame through the second horizontal hinge shaft, when an object supported on the bracket is shifted to be in contact with the trigger plate, the vertical bolt is aligned with the arc avoiding groove, and therefore the reverse osmosis filter is prevented from being transferred to the trigger plate, the transverse driving rod and the vertical bolt which are damaged when being supported by the blocking frame.
