[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] Referring to Figure 1 and Figure 2 The movable diaphragm pressing plate device provided by the first embodiment of the application comprises a membrane box outer frame 1, wherein the membrane box outer frame 1 adopts a cuboid structure and is composed of an upper edge frame 11, a lower edge frame 12 and four supporting rods 13, forming a stable frame system. Two groups of membrane clamping assemblies 2 are installed on the membrane box outer frame 1. The membrane clamping assembly 2 comprises a fixed membrane clamping plate 21 and a movable membrane clamping plate 22. In this embodiment, the fixed membrane clamping plate 21 is fixedly connected with the lower edge frame 12 and is arranged between the two supporting rods 13. The movable membrane clamping plate 22 is arranged above the fixed membrane clamping plate 21 and close to the upper edge frame 11 and is arranged between the two supporting rods 13 and can slide up and down along the supporting rod 13, so as to adjust the distance between the movable membrane clamping plate 22 and the fixed membrane clamping plate 21. In order to realize this connection relationship, further, the movable membrane clamping plate 22 comprises a movable membrane clamping plate body part 221 and a sliding block part 222 arranged at both ends of the movable membrane clamping plate body part 221. One end of the supporting rod 13 close to the upper edge frame 11 is provided with a sliding groove 131 matched with the sliding block part 222. A plurality of diaphragm buckles 23 are arranged on the movable membrane clamping plate 22 and the fixed membrane clamping plate 21. Spaces for fixing the diaphragm 6 are formed between two adjacent diaphragm buckles 23. It can be understood that the diaphragm buckles 23 on the movable membrane clamping plate 22 and the fixed membrane clamping plate 21 are arranged in alignment. A fastening assembly is arranged on the other side of the movable membrane clamping plate 22. The fastening assembly comprises a plurality of first screw rods 3. The first screw rod 3 penetrates through the upper edge frame 11 and is threadedly connected with the upper edge frame 11. After the diaphragm 6 is installed to the membrane box, the first screw rod 3 is rotated clockwise, the first screw rod 3 moves downward, thereby pushing the movable membrane clamping plate 22 to move downward, the diaphragm 6 is fixed between the movable membrane clamping plate 22 and the fixed membrane clamping plate 21, thereby preventing the diaphragm 6 from shaking up and down during the pulse aeration flushing process. In addition, in order to prevent the diaphragm 6 from sliding transversely, the upper edge frame 11 and the lower edge frame 12 are provided with a stop edge 14 close to the membrane clamping assembly 2. The stop edge 14 extends towards the side of the supporting rod 13, effectively limiting the transverse movement of the diaphragm 6. In order to ensure the effectiveness of the stop edge 14, it can be understood that the length of the sliding groove 131 is less than the height of the stop edge 14. It is additionally stated that in this embodiment, the number of the first screw rods 3 can be arranged according to the width of the membrane box outer frame 1, and the plurality of first screw rods 3 are uniformly distributed on one side of the movable membrane clamping plate 22.

[0027] Referring to Figure 3 The second embodiment provided by the utility model differs from the first embodiment in that the fastening assembly comprises springs 4 uniformly distributed between the movable film clamping plate 22 and the upper frame 11, and spring compression assemblies 5 uniformly distributed on the movable film clamping plate 22 and used for compressing the springs 4, wherein the spring compression assemblies 5 comprise a clamping seat 51 and a second screw rod 52, the clamping seat 51 is installed on one side of the movable film clamping plate 22, and the second screw rod 52 penetrates through the upper frame 11 and is threadedly connected with the upper frame 11.

[0028] Referring to Figure 4 Further, the second screw rod 52 comprises a second screw rod body 521 and a clamping head 522 rotatably connected to one end of the second screw rod body 521, and the clamping seat 51 is provided with a clamping groove 511 matched with the clamping head 522, wherein the clamping head 522 comprises a clamping head 522 body in a cylindrical structure, a clamping pin 523 is arranged in a penetrating mode along the radial direction of one end of the clamping head 522 body, the other end of the clamping head 522 body is rotatably connected with the second screw rod body 521, and the clamping groove 511 is arranged on the clamping seat 51 to avoid the clamping head 522, wherein the cross section of the clamping groove 511 is in an L-shaped structure, and the clamping head 522 can be clamped with the clamping seat 51 by being inserted into the clamping groove 511 of the clamping seat 51 and then being rotated. In addition, it should be noted that the diameter of the clamping head 522 body is smaller than the length of the clamping pin 523, and the length of the clamping pin 523 is smaller than the diameter of the internal screw hole in which the second screw rod body 521 is threadedly connected with the upper frame 11. Such a design can make the second screw rod 52 completely separated from the upper frame 11.

[0029] In use, the second screw rod 52 is installed on the upper frame 11, then the second screw rod 52 is rotated clockwise, the second screw rod 52 moves downward until the clamping head 522 touches the clamping seat 51. It should be noted that, since the upper end of the clamping seat 51 is a V-shaped port, the clamping head 522 slides into the L-shaped clamping groove 511 along the V-shaped port while the second screw rod body 521 moves downward, and when the clamping head 522 reaches the bottom end of the L-shaped clamping groove 511, the clamping head 522 is clamped with the clamping seat 51 by being rotated counterclockwise. The second screw rod 52 is continuously rotated counterclockwise, and since the clamping head 522 is rotatably connected with the second screw rod body 521, the second screw rod 52 rises while being rotated counterclockwise, and simultaneously pulls the movable film clamping plate 22 to rise, thereby realizing compression of the spring 4. It should be noted that, when the sliding block part 222 of the movable film clamping plate 22 abuts against the bottom end of the sliding groove 131, the spring 4 is in a natural elongation state; as the second screw rod 52 continues to rise, when the movable film clamping plate 22 abuts against the upper frame 11, the spring 4 is just in a completely compressed state. At this time, since the clamping seat 51 is installed on the movable film clamping plate 22, it can be understood that the upper frame 11 is provided with a recess for avoiding the clamping seat 51.

[0030] With the compression of the spring 4, the distance between the movable clamping plate 22 and the fixed clamping plate 21 increases, and then the diaphragm 6 can be installed on the clamping assembly 2, and then the second screw 52 is rotated clockwise, and with the downward movement of the second screw 52, the movable clamping plate 22 moves downward under the elastic force of the spring 4; see Figure 4 It should be noted that in order to prevent the clamping head 522 from rotating clockwise, the clamping pin 523 from disengaging the horizontal end of the L-shaped clamping groove 511, and the second screw 52 from being disengaged from the clamping seat 51, causing the movable clamping plate 22 to directly hit the diaphragm 6 under the elastic force of the spring 4, a limiting groove 512 for accommodating the clamping pin 523 is arranged at the L-shaped horizontal end of the clamping groove 511, and when the second screw 52 is clamped with the clamping seat 51, the clamping pin 523 is always clamped in the limiting groove 512, and until the movable clamping plate 22 is completely abutted against one end of the diaphragm 6, there is no pulling force between the second screw 52 and the clamping seat 51, and with the continuous downward movement of the second screw 52, the clamping pin 523 is disengaged from the limiting groove 512 and rotated to the vertical end of the L-shaped clamping groove 511, and then the second screw body 521 needs to be counterclockwise rotated, so that the second screw 52 moves upward; however, in order to prevent the clamping head 522 from rotating into the horizontal end of the L-shaped clamping groove 511 along with the second screw body 521, see Figure 5 In this embodiment, the second screw 52 is provided with a clamping head fixing pin 53, wherein the clamping head fixing pin 53 comprises a toothed disc 533, a connecting rod 532, and a pull ring 531, the clamping head 522 is internally provided with a cavity 524 for accommodating the toothed disc 533, and the height of the cavity 524 is greater than the height of the toothed disc 533, the clamping head 522 is internally provided with a tooth groove 525 for forming a toothed connection with the toothed disc 533, one end of the connecting rod 532 is connected with the toothed disc 533, and the other end penetrates through the second screw body 521 away from the clamping head 522, and the end of the connecting rod 532 away from the toothed disc 533 is provided with the pull ring 531. Generally, under the action of gravity, the clamping head fixing pin 53 is located at the lower end of the cavity 524, the toothed disc 533 is disengaged from the tooth groove 525, and the clamping head 522 can be freely rotated, when it is necessary to completely rotate the second screw 52 out of the clamping head 522, only the pull ring 531 needs to be pulled to make the toothed disc 533 toothed with the tooth groove 525, so that the clamping head 522 can be manually fixed, so that the clamping head 522 does not rotate with the second screw body 521, and then the second screw body 521 can be continuously rotated until the clamping pin 523 cannot enter the horizontal end of the L-shaped clamping groove 511, the pull ring 531 can be released, and then the second screw 52 can be continuously rotated until the second screw 52 is separated from the clamping seat 51 or the upper frame 11. After the clamping seat 51 is disengaged from the second screw 52, the movable clamping plate 22 firmly fixes the diaphragm 6 between the movable clamping plate 22 and the fixed clamping plate 21 under the elastic force of the spring 4, solving the problem that the diaphragm 6 is damaged due to the gap between the diaphragm 6 and the clamping assembly 2 during installation and the vibration of the diaphragm 6 during aeration, and at the same time, through the fixed mode of the spring 4, a buffering function is achieved when the diaphragm 6 vibrates.

[0031] In summary, the movable diaphragm pressing plate device in the above-mentioned embodiments of the utility model, through setting the film clamping assembly into movable film clamping plate and fixed film clamping plate, setting fastening assembly on the side of movable film clamping plate, through adjusting fastening assembly, the distance between movable film clamping plate and fixed film clamping plate is changed, because diaphragm is fixed between movable film clamping plate and fixed film clamping plate, so through adjusting fastening assembly, the gap between diaphragm and film clamping assembly during installation can be avoided, at the same time, under the fixing effect of fastening assembly, diaphragm is fixed firmly between film clamping assembly, thereby the damage probability of diaphragm due to violent knock of diaphragm and film clamping assembly is reduced.
