Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment: As Figures 1-4 shown, the present utility model provides an air outlet assembly of an electromagnetic diaphragm pump, including a pump body 1. An air outlet pipe 11 is provided on one side of the pump body 1. A first support ring 12 is detachably installed at the top of the air outlet pipe 11. Symmetrically distributed first threaded rods 13 penetrate through the inside of the first support ring 12 in a threaded manner. At one end of the two first threaded rods 13 close to each other, first positioning rings 14 are movably provided. At the top of the first support ring 12, symmetrically distributed movable rods 15 are fixedly installed. A second threaded rod 16 is provided inside the movable rod 15. Above the first support ring 12, a second support ring 17 is fixedly provided. Symmetrically distributed second positioning rings 18 are movably provided inside the second support ring 17. The second threaded rod 16 is connected to the second support ring 17. On one side of the two second positioning rings 18 away from each other, fixing rods 19 are fixedly installed. The fixing rods 19 penetrate through the second support ring 17. On one side of the two second positioning rings 18 away from each other, springs 191 are fixedly installed. The other end of the spring 191 is fixedly connected to the inner wall of the second support ring 17.

[0018] The movable rod 15 is rotatably installed at the top of the first support ring 12. The second threaded rod 16 is threadedly inserted into the inside of the movable rod 15. At the bottom end of the second support ring 17, symmetrically distributed bearings 2 are fixedly installed. The inner parts of the two bearings 2 are respectively fixedly connected to the corresponding second threaded rods 16.

[0019] On one side of the two first positioning rings 14 and the second positioning rings 18 away from each other, symmetrically distributed limiting rods 3 are fixedly installed. A plurality of limiting rods 3 respectively penetrate through the corresponding first support ring 12 and the second support ring 17. By providing the limiting rods 3, the moving directions of the first positioning rings 14 and the second positioning rings 18 can be limited to avoid deviation and improve their stability.

[0020] On one end of the two first threaded rods 13 and the fixing rods 19 away from each other, sleeve rings 4 are fixedly installed. By providing the sleeve rings 4, it is convenient for the staff to pull the first threaded rods 13 and the fixing rods 19.

[0021] Inside the two first positioning rings 14 and the second positioning rings 18, protective pads 5 are fixedly installed. By providing the protective pads 5, the first positioning rings 14 and the second positioning rings 18 are prevented from wearing the air outlet pipe 11 and the hose.

[0022] A support frame 6 is fixedly installed at the bottom end of the pump body 1. A bottom plate 61 is fixedly installed at the bottom end of the support frame 6. Fixing holes 62 are provided at the four corners of the top end of the bottom plate 61. By providing the support frame 6, the bottom plate 61 and the fixing holes 62, the stability of the pump body 1 is improved, and at the same time, the bottom plate 61 can be fixed by fixing screws.

[0023] Anti-slip pads 7 are symmetrically and fixedly installed at the bottom end of the bottom plate 61 to increase the anti-slip effect of the bottom plate 61 and improve stability.

[0024] The protective pad 5 is made of silica gel material to further prevent abrasion to the air outlet pipe 11 and the hose.

[0025] Working principle: During actual use, the first support ring 12 is placed on the top of the air outlet pipe 11. By rotating the first threaded rod 13, it moves towards the air outlet pipe 11. The first threaded rod 13 drives the first positioning ring 14 to move until it fits with the air outlet pipe 11, completing the installation of the first support ring 12. Subsequently, the fixing rod 19 is pulled in the direction away from the second support ring 17, causing the fixing rod 19 to drive the second positioning ring 18 to move, and the second positioning ring 18 applies pressure to the spring 191 to cause it to deform. Then, the hose is inserted into the air outlet pipe 11 through the middle of the two second positioning rings 18. At this time, the pulling force on the fixing rod 19 is stopped, causing the spring 191 to release its elastic force, driving the second positioning ring 18 to move towards the hose until the two second positioning rings 18 clamp the hose. By rotating the movable rod 15, the second threaded rod 16 is driven to rise. The second threaded rod 16 drives the second support ring 17 to rise through the bearing 2, so that different positions of the hose can be clamped, facilitating adjustment by the staff according to needs.

[0026] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
