[0017] For the convenience of understanding the utility model, the utility model is described more comprehensively through the following examples. The examples give the implementation mode of the utility model. However, the utility model can be realized in many different forms and is not limited to the implementation mode described in the examples.
[0018] It should be noted that the "first", "second" in the utility model are only used for name distinction and do not represent the specific quantity and order.
[0019] One of the implementation modes of the aerator in the utility model is shown in Figure 1 , and comprises an impeller 1 agitating the water surface, a main machine 2 driving the impeller 1 to rotate, a floating ball 3 floating the whole aerator on the water surface, and a connecting rod 4 connected between the floating ball 3 and the main machine 2. Meanwhile, referring to Figure 1 , Figure 2 , Figure 3 , each floating ball 3 is fixed with a first connecting piece 5, and the first connecting piece 5 has two parallel clamping grooves 6. Specifically, the first connecting piece 5 of the example is a sheet metal piece, and the two clamping grooves 6 are stamped from the sheet metal piece. The sheet metal piece is fixed on the top of the floating ball 3 by means of a clamp 7. The connecting rod 4 is fixed with a second connecting piece 8 corresponding to the first connecting piece 5. The second connecting piece 8 of the example is an end plate fixed on the end of the connecting rod 4. The end plate 8 can be fixed on the end of the connecting rod 4 in the mode of welding, screw connection or integral forming with the connecting rod. The two parallel opposite edges of the end plate 8 are respectively inserted into the clamping grooves 6 from the ends of the two clamping grooves 6 along the length direction of the clamping grooves 6. The shape of the two clamping grooves 6 restricts that the end plate 8 can only slide up and down along the length direction of the two clamping grooves 6.
[0020] Meanwhile, referring to Figure 2 , Figure 3 , Figure 4 , the first connecting piece 5 is provided with a positioning hole 9, and correspondingly, the second connecting piece 8 is provided with a spring pin corresponding to the positioning hole 9. The spring pin is composed of a spring 10 and a pin 11. The spring 10 is fixed on the second connecting piece 8 in the mode of riveting or welding, or can be directly fixed on the end face of the connecting rod 4. As long as the two parallel opposite edges of the end plate 8 are inserted into the clamping grooves 6, the pin 11 can be inserted into the positioning hole 9 under the action of the spring 10, so as to lock the sliding of the end plate 8 relative to the first connecting piece 5, so that the first connecting piece 5 is fixed on the end plate 8, that is, fixed on the second connecting piece 8, and the floating ball 3 and the connecting rod 4 are connected into an integral whole. This connection process does not require any tool and is convenient and fast. Conversely, as long as the pin 11 is made to overcome the elastic force of the spring 10 and exit from the positioning hole 9 by external force, the end plate 8 can be slid out of the clamping grooves 6 of the first connecting piece 5 as shown in Figure 3 , so as to separate the floating ball 3 and the connecting rod 4. This disassembly process does not require any tool and is convenient and fast. As the best implementation mode, the spring 10 of the example is a spring sheet, and the pin 11 is fixed on the spring sheet 10 in the mode of riveting or welding.
[0021] As the best embodiment, the end plate 8 of the present embodiment restricts the direction of the translational sliding of the first connecting member 5 to be the up-and-down sliding. Figure 3 As shown, the positioning holes 9 provided on the first connecting member 5 are provided in multiple along the height direction. The height of the floating ball 3 relative to the connecting rod 4 can be adjusted by inserting the pin 11 into the positioning holes 9 of different heights, which is more convenient for use.
[0022] It should be noted that the positions of the positioning holes 9 and the spring pins can be interchanged. The positioning holes 9 are provided on the second connecting member 8, and the spring pins corresponding to the positioning holes are provided on the first connecting member 5. The positions of the end plate 8 and the two clamping grooves 6 can also be interchanged. The end plate 8 in Figure 2 is modified to be the first connecting member of the floating ball 3, and the first connecting member 5 with the two clamping grooves 6 in Figure 2 is modified to be the second connecting member of the end of the connecting rod 4.
[0023] Another embodiment of the present utility model is shown in Figure 5 . The first connecting member of the present embodiment is a first square tube 12 fixed on the floating ball 3, and the second connecting member is a second square tube 13 fixed on the end of the connecting rod 4. The first square tube 12 is sleeved in the second square tube 13, and the second square tube 13 restricts the first square tube 12 to only slide up and down along the length direction of the second square tube 13. Meanwhile, referring to Figure 5 , Figure 6 , Figure 7 , the spring pin of the present embodiment is composed of a spring sheet 10 and a pin 11. The pin 11 is fixed on the spring sheet 10 by riveting or welding. The spring sheet 10 is fixed on the second square tube 13 by rivets 14 or by welding. The positioning holes 9 corresponding to the pin 11 are provided on the first square tube 12. When the first square tube 12 is sleeved into the second square tube 13 as shown in Figure 5 , the pin 11 is inserted into the positioning holes 9 by the action of the spring sheet 10, so as to lock the sliding of the first square tube 12 relative to the second square tube 13. The first square tube 12 and the second square tube 13 are fixed together, and the floating ball 3 and the connecting rod 4 are connected into one body. When the floating ball 3 needs to be disassembled, the curved spring sheet 10 is bent by hand, so that the pin 11 is withdrawn from the positioning holes 9, and the first square tube 12 can be slid out of the second square tube 13.
[0024] As the best embodiment, the second square tube 13 of the present embodiment restricts the direction of the translational sliding of the first square tube 12 to be the up-and-down sliding, and the positioning holes 9 provided on the first square tube 12 are provided in multiple along the height direction. The height of the floating ball 3 relative to the connecting rod 4 can be adjusted by inserting the pin 11 into the positioning holes 9 of different heights.
[0025] It should be noted that the position of the positioning hole 9 and the spring pin of the embodiment can be interchanged, the positioning hole 9 is arranged on the second square tube 13, and the spring pin corresponding to the positioning hole 9 is arranged on the first square tube 12.
[0026] It should be noted that the embodiment can also be that the second square tube 13 is sleeved in the first square tube 12.
[0027] It should be noted that the first connecting piece and the second connecting piece of the utility model are not limited to the illustrated embodiment. For example, the second connecting piece can be a dovetail groove, and correspondingly, the first connecting piece can be a dovetail-shaped slider sleeved in the dovetail groove. The sliding connection of such a dovetail groove structure can also constrain the first connecting piece to only perform translational sliding along the second connecting piece.
[0028] It should be noted that the sliding direction of the first connecting piece along the second connecting piece is not limited to the up-down sliding of the illustrated embodiment, but can also be horizontal sliding or oblique sliding at a certain inclination angle with the horizontal plane. For example, the length direction of the two clamping grooves 6 in the Figure 1 or the length direction of the second square tube 13 in the Figure 5 may be changed to horizontal transverse, and the end plate 8 is inserted into the clamping groove 6 in the horizontal direction, or the first square tube 12 is sleeved into the second square tube 13 in the horizontal direction; for another example, Figure 1 the length direction of the two clamping grooves 6 in the Figure 5 or the length direction of the second square tube 13 in the may be changed to 45 degrees inclined angle with the horizontal plane. And so on are the alternative embodiments of the utility model.
