Description

Technical Field

[0001] The utility model relates to the technical field related to brackets, in particular to an aerator bracket. Background Art

[0002] Aerator is a machine commonly used in fishery breeding. 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. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pond water from threatening the living environment of the fish. Aerators are generally composed of several floats, impellers, impeller shafts and motors. Several floats carry impellers, impeller shafts and motors. The impeller is installed on the impeller shaft. The impeller shaft is supported by the bracket on the float and driven to rotate by the motor. In the past, the bracket was generally a fixed bracket, which was first installed on the float and then the impeller shaft was installed. During installation, the impeller shaft needs to pass through each bracket in turn. However, when the number of floats is large and the impeller shaft is long, the installation becomes very complicated and difficult to position, which seriously affects the installation efficiency. Therefore, some brackets that are convenient for positioning and installing the impeller shaft of the aerator have been invented, as follows.

[0003] After searching, the patent with the authorization publication number CN208657698U discloses an aerator bracket, including a bracket body, a cover plate and a sleeve; the cover plate is connected to the bracket body up and down, the cover plate is provided with an upper concave hole, the bracket body is provided with a lower concave hole, the upper concave hole and the lower concave hole are relatively formed into a connecting hole, the sleeve is sleeved inside the connecting hole, the front and rear ends of the sleeve are connected with a first chuck and a second chuck, the first chuck and the second chuck are respectively pressed and connected to the two ends of the connecting hole. The aerator bracket described in the utility model can ensure that even when the number of floats is large, the impeller shaft and the bracket can be easily assembled.

[0004] However, the above patent still has the following aspects that can be optimized:

[0005] Although it can well position and install the impeller shaft, the connection and fixation between the cover plate and the bracket body are connected and fixed by multiple bolts, and the installation and removal of the bolts require the use of matching installation and removal tools, and the installation and removal of the bolts are time-consuming and labor-intensive, which makes the installation and subsequent removal between the cover plate and the bracket body time-consuming and labor-intensive, and inefficient, thereby reducing the overall installation work efficiency. At the same time, the bolts may loosen and fall off due to long-term vibration in daily work, which will affect the normal operation of the bracket and the impeller shaft. Therefore, its overall structure needs to be improved and its practicality needs to be improved. Utility Model Content
