Technical Field

[0001] The utility model relates to the field of aeration equipment, in particular to a disc-type aeration head which is convenient to assemble. Background Art

[0002] Aeration is a means of bringing air and water into strong contact, with the purpose of dissolving oxygen in the air into the water, or expelling unwanted gases and volatile substances in the water into the air. In other words, it is a means of promoting the exchange of substances between gas and liquid. There are many types of aerators, such as disc aerators, cyclone aerators, tube aerators, etc. Among them, disc aerators use several nano-scale microporous structures on the disc surface to "cut" the gas and separate it into several tiny bubbles.

[0003] The disc aerator includes a base 00 and a disc surface 01, which are generally connected by threads. Although this connection structure has strong stability, it is inconvenient during installation: due to the large diameters of the base 00 and the disc surface 01, it is not convenient to drive the two to rotate relative to each other during installation (the two can only achieve thread locking when they rotate relative to each other).

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] According to the conveniently assembled disc aeration head of the utility model, the buckling space of the hook claw is the same shape as the connecting column.

[0010] According to the convenient-to-assemble disc-type aeration head of the utility model, the hook is a semi-enclosed structure, and the enclosed area thereof is larger than 1 / 2 of the surface.

[0011] According to the conveniently assembled disc aerator of the utility model, the positioning structure comprises an embedding groove arranged on the side wall of the peripheral surface of the connecting column and an inserting block arranged on the locking member; during installation, the inserting block is inserted into the embedding groove.

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1 and Figure 2 The utility model provides a disc aeration head that is easy to assemble. The disc aeration head that is easy to assemble includes a plurality of connecting columns 1 arranged on the outer edge of the disc surface 01 and a locking member 03 installed on the base 00 and connected to the connecting columns 1. When installed, the disc surface 01 and the base 00 are coaxially buckled. In this embodiment, in order to increase the uniform distribution of force during locking and ensure the sealing of the connection between the disc surface 01 and the base 00, a plurality of connecting columns 1 are arranged at equal intervals at the outer edge of the disc surface 01. The outer edge of the base 00 is provided with a through hole 04 for the connecting column 1 to pass through. When buckled and installed, the connecting column 1 is correspondingly inserted into the through hole 04.

[0024] See also Figure 3 The locking member is an annular structure, and a plurality of positioning structures are arranged on its outer edge to correspond to the connecting column 1 and realize the axial fixation of the disk 01 and the base 00.

[0025] In this embodiment, the positioning structure includes a protrusion 11 provided at the end of the connecting column 1 and a hook 12 provided on the locking member 03; the hook 12 is buckled outside the connecting column 1, and the side end of the hook 12 is pressed and fitted with the side end of the protrusion 11. To ensure the stability of the hook 12 when it is buckled with the connecting column 1, the buckling space of the hook 12 is the same shape as the connecting column 1. At the same time, the hook 12 is a semi-enclosed structure, and its enclosed area is larger than 1 / 2 of the surface. During the buckling process (rotating the locking member 03), the hook 12 will undergo a predetermined deformation, through which a pre-tightening force can be provided to prevent the connecting column 1 from slipping out after the hook 12 is matched (buckled) with the connecting column 1, thereby increasing the stability of the buckling.

[0026] See also Figure 5In another embodiment, the positioning structure includes an embedding groove 14 provided on the side wall of the peripheral surface of the connecting column 1 and an insert block 15 provided on the locking member 03; during installation (rotating the locking member 03), the insert block 15 is inserted into the embedding groove 14. Similarly, the insert block 15 is a deformable insert block with a "T"-shaped structure. When the insert block 15 is inserted into the embedding groove 14, the insert block 15 undergoes a predetermined deformation.

[0027] Preferably, after the locking member is sleeved on the base 00, the lower edge of the locking member has a driving portion 16 ( Figure 4 As shown), during the process of driving the locking member 03 to rotate, the driving part 16 can be held by hand to conveniently drive the locking member 03 to rotate.

[0028] In addition, a plurality of rubber protrusion structures 17 are provided on the inner wall of the locking member 03 of the utility model. Through this structure, on the one hand, the friction between the palm and the component is increased during driving, thereby optimizing the driving effect of the driving part 16. On the other hand, after the positioning structure is matched, this structure can increase the static friction between the locking member 03 and the base 00, thereby providing stability for the positioning structure (preventing the locking member 03 from rotating in the opposite direction).

[0029] In summary, the utility model provides a disc aeration head that is easy to assemble, including a plurality of connecting columns arranged on the outer edge of the disc surface and a locking member installed on the base and connected to the connecting columns; when installed, the disc surface and the base are coaxially buckled; in order to increase the uniform distribution of force during locking and ensure the sealing of the connection between the disc surface and the base, a plurality of the connecting columns are evenly spaced and arranged at the outer edge of the disc surface. A through hole for the connecting column to pass through is arranged at the outer edge of the base, and the connecting column is correspondingly inserted into the through hole during buckling installation. The locking member is an annular structure, and a plurality of positioning structures corresponding to the connecting column and realizing axial fixation of the disc surface and the base are arranged on its outer edge. The positioning structure includes a protrusion arranged at the end of the connecting column and a hook arranged on the locking member; the hook is buckled outside the connecting column, and the side end of the hook is pressed and fitted with the side end of the protrusion. In order to ensure the stability of the hook when it is buckled with the connecting column, the buckling space of the hook is the same shape as the connecting column. During the buckling process (rotating the locking piece), the hook will undergo a predetermined deformation, and through this deformation, after the hook is matched with the connecting column (buckled), a pre-tightening force can be provided to prevent the connecting column from coming out, thereby increasing the stability of the buckling. The utility model can realize the locking and positioning between the base and the disk through the locking piece, and during the connection process, the relative rotation of the base and the disk is converted into the rotation of the locking piece, making it more convenient to drive the components.
