Description

Technical Field

[0001] The utility model belongs to the technical field of oxygenators, relates to an oxygenator, and particularly relates to an oxygenator which is convenient to assemble and disassemble. Background Art

[0002] Aerator is a machine commonly used in fish farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be deprived of oxygen. It can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the living environment of the fish.

[0003] The connection between the motor body of the existing aerator and the connecting rod for installing the float is often made by bolt connection, which requires tools and twisting the bolts to achieve fixation, and the installation speed is slow. Summary of the invention

[0004] The utility model aims to provide an aerator which is easy to assemble and disassemble in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an aerator that is easy to disassemble and assemble, comprising a base, a driving motor is arranged on the base, the motor shaft of the driving motor passes through the base and is connected to an impeller for oxygenation, characterized in that a plurality of floats are arranged on the base, a connecting rod is arranged between the float and the base, a mounting portion is arranged on one end of the connecting rod, a placement groove for placing the mounting portion is opened on the base, a fixing portion is arranged on both sides of the mounting portion, a clamping device is arranged on the base and on the side relative to the fixing portion, a mounting groove for installing the clamping device is opened on the base, the clamping device consists of a reset spring, an extrusion block and a fixed block, limit blocks are arranged on both sides of the fixed block, and a limit sliding groove for allowing the limit block to move is opened on the base and on the side relative to the limit block.

[0006] In the above-mentioned aerator that is easy to assemble and disassemble, a limiting portion for limiting the extrusion block is arranged on the base and relative to the upper end of the installation groove.

[0007] In the above-mentioned aerator that is easy to assemble and disassemble, there are three floats, the other end of the connecting rod is provided with a connecting part for connecting the float, the float is provided with a connecting column, the connecting part is provided with a connecting hole for the connecting column to enter, the upper end of the connecting column is provided with a fixing knob, and the fixing knob and the connecting column are connected by a thread.

[0008] Compared with the prior art, the present invention uses a snap-on device. It only requires the connecting rod to place the installation part in the prevention groove according to the position, and then move the fixed block to make the fixed block reach the upper end of the fixed part. The extrusion block is not constrained by the fixed block, and the reset spring quickly resets the extrusion block. The snap-on connection is very convenient and does not require tools. After installing the float, the connecting column is passed through the connecting hole and then the fixing knob is installed to complete the fixation, making the installation of the float faster. The extrusion block prevents the fixed block from moving left and right, and the limit part and the limit slide prevent the fixed block from moving up and down. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 As shown, the aerator which is easy to disassemble and assemble comprises a base 2, on which a driving motor 1 is arranged, the motor shaft of the driving motor 1 passes through the base 2 and is connected with an impeller 3 for oxygenation, a plurality of floats 4 are arranged on the base 2, a connecting rod 5 is arranged between the float 4 and the base 2, a mounting portion 6 is arranged on one end of the connecting rod 5, a placement groove 7 for placing the mounting portion 6 is provided on the base 2, fixing portions 8 are provided on both sides of the mounting portion 6, a clamping device 9 is provided on the base 2 and on the side relative to the fixing portion 8, a mounting groove 10 for installing the clamping device 9 is provided on the base 2, the clamping device 9 consists of a reset spring 11, an extrusion block 12 and a fixing block 13, limit blocks 14 are arranged on both sides of the fixing block 13, and a limit sliding groove 15 for allowing the limit block 14 to move is provided on the base 2 and on the side relative to the limit block 14.

[0016] To be more specific, a limiting portion 16 for limiting the extrusion block 12 is disposed on the base 2 and relative to the upper end of the mounting groove 10 .

[0017] To elaborate further, there are three floats 4, and the other end of the connecting rod 5 is provided with a connecting portion 17 for connecting the float 4, a connecting column 18 is provided on the float 4, and a connecting hole 19 for the connecting column 18 to enter is opened on the connecting portion 17, and a fixing knob 20 is provided on the upper end of the connecting column 18, and the fixing knob 20 and the connecting column 18 are connected by threads.

[0018] Working principle: only the connecting rod 5 is needed to place the mounting part 6 in the prevention groove according to the position, and then the fixing block 13 is moved so that the fixing block 13 reaches the upper end of the fixing part 8. The extrusion block 12 is not constrained by the fixing block 13. The reset spring 11 quickly resets the extrusion block 12. The extrusion block 12 prevents the fixing block 13 from moving left and right. The limiting part 16 and the limiting slide groove 15 prevent the fixing block 13 from moving up and down. The clamping can be completed very conveniently and no tools are required.
