In the utility model, when it is needed to fix and seal multiple No. 2 flange pipes and multiple No. 1 flange pipes during use, the four rectangular slides are driven to move synchronously by the sliding assembly. When the two rectangular slides on the same side move toward each other, the eight connecting rods and the eight arc-shaped extrusion blocks are driven to move synchronously. When the four matching arc-shaped extrusion blocks are in contact with the outer walls of the peripheral sides of the No. 2 flange pipe and the No. 1 flange pipe, the four arc-shaped extrusion blocks stop lateral movement due to the extrusion effect. At this time, the two rectangular slides continue to move, and the connecting rod is flipped under the extrusion effect, and the limit rod is squeezed. Since the hollow slider is slidably arranged in the sliding hole, the flipping of the connecting rod is not affected.

Specifically, when the rectangular slide moves in the opposite direction to reset, the squeezing effect on the connecting rod disappears. At this time, the elastic function of the compression spring can drive the connecting rod to achieve the reset function, thereby driving the hollow slider to reset synchronously.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 The reverse osmosis water treatment equipment shown in the figure includes a mounting frame 1, four reverse osmosis unit tubes, a liquid inlet sleeve, a liquid outlet sleeve, an air pump, an air pipe, two liquid outlet curved pipes 2, four No. 2 flange pipes 3, and four No. 1 flange pipes 4. The four reverse osmosis unit tubes, the liquid inlet sleeve, the liquid outlet sleeve, the air pump, the air pipe, the two liquid outlet curved pipes 2, the four No. 2 flange pipes 3, and the four No. 1 flange pipes 4 are all arranged on the mounting frame 1. It should be noted that in this embodiment, the installation method of the four reverse osmosis unit tubes, the liquid inlet sleeve, the liquid outlet sleeve, the air pump, the air pipe, the two liquid outlet curved pipes 2, the four No. 2 flange pipes 3, and the four No. 1 flange pipes 4 can refer to the technical content adopted in a reverse osmosis water treatment device disclosed in the Chinese patent with publication number CN220149326U in the prior art, which will not be repeated here. The relative inner walls of the mounting frame 1 are provided with two Rectangular grooves, rectangular slides 5 are slidably installed in the four rectangular grooves through sliding single components, two limit units are arranged on the sides of the four rectangular slides 5, the limit units include two connecting rods 10, one ends of the two connecting rods 10 are rotatably installed on the sides of the rectangular slide 5, the other ends of the two connecting rods 10 are rotatably installed with arc extrusion blocks 11, the two arc extrusion blocks 11 are respectively adapted to the No. 2 flange tube 3 and the No. 1 flange tube 4, a sliding hole 13 is opened on the side of the rectangular slide 5, two hollow sliders 14 are slidably installed in the sliding hole 13, limiting rods 15 are slidably installed in the two hollow sliders 14, one ends of the two limit rods 15 are respectively rotatably installed on the sides of the two connecting rods 10, the other ends of the two limit rods 15 extend to the outside of the two hollow sliders 14, and elastic units are arranged on the sides of the two hollow sliders 14.

[0023] By means of the above structure, when it is necessary to fix and seal multiple No. 2 flange tubes 3 and multiple No. 1 flange tubes 4, the four rectangular slides 5 are driven to move synchronously by the sliding assembly. When the two rectangular slides 5 on the same side move toward each other, the eight connecting rods 10 and the eight arc-shaped extrusion blocks 11 are driven to move synchronously. When the four matching arc-shaped extrusion blocks 11 contact the outer walls of the No. 2 flange tube 3 and the No. 1 flange tube 4, the four arc-shaped extrusion blocks 11 stop lateral movement due to the extrusion effect. At this time, since the two rectangular slides 5 continue to move, the four arc-shaped extrusion blocks 11 stop lateral movement due to the extrusion effect. Movement, the extrusion action causes the connecting rod 10 to flip over and squeezes the limit rod 15. Since the hollow slider 14 is slidably set in the sliding hole 13, the flipping of the connecting rod 10 will not be affected. When the connecting rod 10 flips, it drives the arc-shaped extrusion block 11 to move toward the flange until the two ends of the two flanges are squeezed by the four arc-shaped extrusion blocks 11, so that the sealing connection function is realized. In this way, the connection points of the four No. 2 flange pipes 3 and the No. 1 flange pipe 4 can be sealed at the same time, which greatly improves the installation and disassembly efficiency.

[0024] like Figure 2 As shown, the sliding assembly includes four bidirectional screw rods 6, both ends of which are rotatably installed on the relative inner walls of four rectangular grooves, and the four bidirectional screw rods 6 are connected by a transmission unit. The four rectangular slides 5 are respectively threadedly installed on the four bidirectional screw rods 6. The advantage of this arrangement is that through the arrangement of the four bidirectional screw rods 6, the horizontal movement function of driving the four rectangular slides 5 can be realized.

[0025] Specifically, when the four bidirectional screw rods 6 rotate, the four rectangular slides 5 are driven to move synchronously under the action of the threads, and then the multiple connecting rods 10 and the multiple arc-shaped extrusion blocks 11 are driven to move synchronously, so as to facilitate the sealing connection of the connection between the No. 2 flange pipe 3 and the No. 1 flange pipe 4.

[0026] like Figure 2 As shown, the transmission unit includes four sprockets 7, and the four sprockets 7 are respectively fixedly sleeved on four bidirectional screw rods 6, and chains 8 are installed on the four sprockets 7 in meshing with each other, wherein a connecting hole is commonly opened on the inner walls of the sides of two rectangular grooves close to each other, and the chain 8 is arranged in the connecting hole, and a driving motor 9 is fixedly installed on the side of the mounting frame 1, and the output shaft of the driving motor 9 is connected to the end of one of the bidirectional screw rods 6. The advantage of such an arrangement is that the function of driving the four bidirectional screw rods 6 to rotate synchronously can be realized through the arrangement of the four sprockets 7 and the chain 8.

[0027] Specifically, the driving motor 9 is started to drive one of the bidirectional screw rods 6 and the sprocket 7 to rotate, and then the other three sprocket wheels 7 and the bidirectional screw rods 6 are driven to rotate synchronously under the meshing action of the sprocket 7 and the chain 8 to prevent the rectangular slide plate 5 from getting stuck during the horizontal movement.

[0028] like Figure 4 As shown, a protective pad 12 is provided on the inner wall of the circumference of the arc-shaped extrusion block 11. The advantage of such a setting is that the protective pad 12 can realize the protection function of the No. 2 flange pipe 3 and the No. 1 flange pipe 4.

[0029] Specifically, when the arc-shaped extrusion block 11 contacts the peripheral outer walls of the second flange pipe 3 and the first flange pipe 4, the provision of the protection pad 12 can achieve a certain buffering protection function to prevent damage to the second flange pipe 3 and the first flange pipe 4.

[0030] like Figure 4 As shown, the elastic unit includes a compression spring 16, one end of the compression spring 16 is fixedly installed on the side of the hollow slider 14, and the other end of the compression spring 16 is fixedly installed on the side of the connecting rod 10. The advantage of this arrangement is that, through the arrangement of the compression spring 16, when the squeezing effect on the connecting rod 10 is released, the elastic function of the compression spring 16 can drive the connecting rod 10 to reset.

[0031] Specifically, when the rectangular slide plate 5 moves in the reverse direction to reset, the squeezing effect on the connecting rod 10 disappears. At this time, the elastic function of the compression spring 16 can drive the connecting rod 10 to achieve the reset function, thereby driving the hollow slider 14 to reset synchronously.

[0032] like Figure 1 As shown, a plurality of universal wheels 17 are arranged at the bottom of the mounting frame 1. The advantage of such arrangement is that the mounting frame 1 can be conveniently moved by the arrangement of the universal wheels 17.

[0033] Specifically, when the mounting frame 1 needs to be moved, the staff only needs to push the mounting frame 1 to realize the convenient moving function through the function of the universal wheels 17 .

[0034] like Figure 1 As shown, a plurality of universal wheels 17 are provided with self-locking parts. The advantage of such a configuration is that by providing the self-locking parts on the universal wheels 17 , a convenient fixing function of the mounting frame 1 can be achieved.

[0035] Specifically, when the mounting frame 1 is moved to a suitable position, the mounting frame 1 can be fixed by self-locking the universal wheels 17 through the self-locking members on the universal wheels 17. The fixing operation is simple and convenient.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
