[0019] In order to facilitate the understanding of the present application, the present application will be described more comprehensively by examples. The examples give the implementation of the present application. However, the present application can be realized in many different forms, and is not limited to the implementation described in the examples.
[0020] It should be noted that the "first", "second" in the present application are only used for name distinction, and do not represent the specific quantity and order.
[0021] One embodiment of the oxygenator in the present application Figure 1 is shown, which comprises a water surface stirring impeller 1, a main machine 2 driving the impeller 1 to rotate, a floating ball 3 floating the whole oxygenator on the water surface, and a floating ball connecting rod 4 connected between the floating ball 3 and the main machine 2. The upper half of the main machine 2 is a motor, and the lower half is a gear box. Meanwhile, referring to Figure 1 , Figure 2 , one end of each floating ball connecting rod 4 is fixed with a first connecting piece 5. The first connecting piece 5 in the present embodiment is an end plate fixed at the end of the floating ball connecting rod. The end plate 5 can be fixed at the end of the floating ball connecting rod 4 in a way of welding, screw connection or integral forming with the floating ball connecting rod. The shell of the main machine 2 is fixed with a second connecting piece corresponding to the first connecting piece 5. Meanwhile, referring to Figure 2 , Figure 3 , the second connecting piece in the present embodiment is two parallel clamping grooves 6a, 6b fixed on the shell of the main machine (because of the visual angle being blocked, Figure 3 only the lower end surface of the clamping groove 6a can be seen, and the whole clamping groove 6a cannot be seen). The two clamping grooves 6a, 6b can be fixed on the shell of the main machine in a way of welding or integral forming with the shell of the main machine. The two parallel opposite sides of the end plate 5 are respectively inserted into the clamping grooves 6a, 6b from the lower ends of the two parallel clamping grooves 6a, 6b along the length direction of the clamping grooves. The shape of the two clamping grooves 6a, 6b restricts the end plate 5 to only slide up and down along the length direction of the two clamping grooves 6a, 6b.
[0022] See also Figure 2 , Figure 3 The end plate 5 is provided with positioning holes 7, and the outer casing of the main unit 2 is equipped with a spring pin consisting of a spring and a pin 8 (the spring is not shown in the figure). By simply inserting the two parallel opposite sides of the end plate 5 into the slots 6a and 6b, the pin 8 will automatically insert into the positioning hole 7 under the action of the spring, thereby locking the end plate 5 relative to the slots 6a and 6b and fixing the end plate 5 to the outer casing of the main unit 2, thus connecting the float connecting rod 4 to the main unit 2 as a single unit. This connection process requires no tools and is convenient and quick.
[0023] See also Figure 2 , Figure 3 The main unit 2 has a single-ended open blind tube 9 integrally formed on its outer casing. The spring pin uses a compression spring, which is placed at the bottom of the blind tube 9 (the compression spring is not shown in the figure). The pin 8 of the spring pin is placed inside the blind tube 9. One end of the pin 8 rests against the compression spring, and the other end... Figure 3 As shown, it extends from the open end of the blind tube 9 and as... Figure 2 The pin 8 is inserted into the positioning hole 7 of the end plate 5 as shown. When the pin 8 retracts into the blind tube 9 under the action of external force, overcoming the elastic force of the compression spring, the pin 8 exits from the positioning hole 7, and then it can be inserted as shown. Figure 3 As shown, slide the end plate 5 out of the slots 6a and 6b to separate the float connecting rod 4 from the main unit 2. This disassembly process requires no tools and is convenient and quick.
[0024] For the best implementation, see also Figure 2 , Figure 3 The pin 8 is connected to a handle 10. The side wall of the blind tube 9 has a sliding hole 11. The handle 10 extends from the sliding hole 11 and can slide along it. When disassembling the float connecting rod, the handle 10 is turned by hand, causing the pin 8 to retract into the blind tube 9. In the preferred embodiment, the handle 10 is a screw connected to the pin 8.
[0025] It should be noted that the positions of the end plate 5 and the two slots 6a and 6b in this embodiment can be interchanged. The end plate 5 can be fixed to the main unit housing as a second connector, and the slots 6a and 6b can be set at the end of the float connecting rod 4 as a first connector, or an accessory with slots 6a and 6b can be fixed at the end of the float connecting rod 4.
[0026] It should be noted that the end plate 5 in this embodiment is not limited to the shape of the illustrated embodiment; for example, it can be made of... Figure 4 The structure shown. Figure 4 The end plate 5 shown is a hollow flat tube, which can be formed by flattening hollow tubing. This type of end plate is more robust.
[0027] Another embodiment of this utility model is, for exampleFigure 5 The first connecting member of the embodiment is a first square tube 12 fixed at the end of the floating ball connecting rod 4, and the second connecting member is a second square tube 13 fixed on the shell of the main machine 2, and the first square tube 12 is sleeved outside the second square tube 13. 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. Please refer to Figure 5 、 Figure 6 、 Figure 7 The spring pin of the embodiment is composed of a spring sheet 14 and a pin 8 fixed on the spring sheet 14. One end of the spring sheet 14 is fixed on the first square tube 12 by a rivet 15 or by welding. A positioning hole 7 corresponding to the pin 8 is formed on the second square tube 13. When the first square tube 12 is sleeved on the second square tube 13 as shown in Figure 5 , the pin 8 is inserted into the positioning hole 7 under the action of the spring sheet 14, thereby locking the sliding of the first square tube 12 relative to the second square tube 13, fixing the first square tube 12 on the shell of the main machine 2, and connecting the floating ball connecting rod 4 and the main machine 2 into an integrated body. When it is needed to disassemble the floating ball connecting rod 4, the bent spring sheet 14 is bent by hand to make the pin 8 exit from the positioning hole 7, and then the first square tube 12 can be slid off from the second square tube 13.
[0028] It should be noted that the position of the positioning hole 7 and the spring pin of the embodiment can be interchanged, and the positioning hole 7 is formed on the first square tube 12, and the spring pin corresponding to the positioning hole 7 is arranged on the second square tube 13.
[0029] It should be noted that the embodiment can also be that the first square tube 12 is sleeved inside the second square tube 13.
[0030] It should be noted that the first connecting member and the second connecting member described in the utility model are not limited to the illustrated embodiment. For example, the second connecting member can be a dovetail groove, and correspondingly, the first connecting member can be a dovetail-shaped sliding block sleeved in the dovetail groove. The sliding connection of the dovetail groove structure can also restrict the first connecting member to only slide along the second connecting member.
[0031] It should be noted that the sliding direction of the first connecting member along the second connecting member is not limited to the up-and-down sliding of the illustrated embodiment, and can also be horizontal sliding or oblique sliding at a certain inclination angle with the horizontal plane. For example, Figure 1 The length direction of the two clamping grooves 6a, 6b in Figure 5 or the length direction of the second square tube 13 in Figure 1 may be changed into horizontal transverse direction, and the end plate 5 is inserted into the clamping groove in the horizontal direction, or the first square tube 12 is sleeved on the second square tube 13 in the horizontal direction; for another example, Figure 5The length direction of the second party pipe 13 in the second embodiment is changed to be 45 degrees with the horizontal plane.
[0032] The above embodiments only express several embodiments of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent protection scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of variations and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
