DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The cross-flow fan blade mounting structure has an outer shell 1;

[0023] like Figures 1 to 5 As shown, a drive shaft 2 is provided at one end of the outer casing 1, and a motor 3 is installed on one side of the outer casing 1. The output end of the motor 3 is connected to the corresponding end of the drive shaft 2. A cross-flow fan assembly 4 is provided inside the outer casing 1. An end cover 5 is provided at one end of the cross-flow fan assembly 4. A steel shaft 6 is fixedly connected to the center of the end cover 5. A connector 7 is provided at the opposite end of the drive shaft 2 and the steel shaft 6. The connectors 7 are aligned and inserted into each other. A hemispherical block 8 is rotatably connected to the center of the connector 7. The hemispherical blocks 8 of the two connectors 7 fit together. A movable hole 9 is opened inside the connector 7. A long rod 10 is slidably connected in the movable hole 9. One end of the long rod 10 is fixedly connected to the corresponding hemispherical block 8.

[0024] Connectors 7 are provided at the corresponding ends of the drive shaft 2 and the cross-flow fan assembly 4. These connectors 7 have a special plug-in mechanism that can quickly and securely connect them together. Compared with the traditional bolt fastening method, this plug-in mechanism greatly simplifies the installation process and improves the stability of the connection before connecting the joints.

[0025] like Figures 1 to 5 As shown, each connector 7 has a groove 11 on the upper part of its opposite end and a plug-in part 12 on the lower part of its opposite end. The groove 11 and plug-in part 12 between the two connectors 7 are arranged in an alternating manner, and the plug-in part 12 of one connector 7 is slidably inserted into the groove 11 of the other connector 7.

[0026] When the plug part 12 is inserted into the groove 11, it will press the inclined horizontal surface of the hemisphere 8, causing the hemisphere 8 to rotate. At the same time, the long rod 10 slides in the movable hole 9, and the spring 13 is stretched and stored. When the plug part 12 is completely submerged in the groove 11, the two hemispheres 8 fit together to form a complete sphere. At this time, the elastic force of the spring 13 drives the hemispheres 8 to rotate, causing the two fitted hemispheres 8 to rotate synchronously. Their horizontal surfaces tilt again, thereby locking the two connectors 7 and achieving a stable connection.

[0027] like Figures 1 to 5 As shown, springs 13 are provided on the outer side of each connector 7. One end of the spring 13 is fixedly connected to the corresponding connector 7, and the other end of the spring 13 is fixedly connected to one end of the corresponding long rod 10. The long rod 10 is elastically connected to the corresponding connector 7 through the spring 13. The hemispherical block 8 is restricted by the spring 13, so that its horizontal plane is inclined. This inclined state makes a part of the hemispherical block 8 in the groove 11.

[0028] As Figures 1 to 5 shown, the other end of the shell 1 is internally fixedly connected with a plug-in shaft 14, the other end of the cross-flow fan blade assembly 4 is provided with a sleeve 15, the inner diameter of the sleeve 15 matches the outer diameter of the plug-in shaft 14, the plug-in shaft 14 is slidingly plugged in the inside of the sleeve 15, when the plug-in shaft 14 is plugged, the sleeve 15 of the other end of the cross-flow fan blade assembly 4 is first sleeved on the outside of the plug-in shaft 14, so that when the cross-flow fan blade assembly 4 rotates, the other end thereof is stably supported by the plug-in shaft 14.

[0029] As Figures 1 to 5 shown, the bottom of the shell 1 is provided with an ear 16 at each corner, and a small hole 17 is formed in the surface of the ear 16, the ear 16 is used to provide a basis for installation or fixation, and the small hole 17 allows a bolt, screw or other fastener to pass through, so as to firmly install the entire installation structure to a predetermined position or support.

[0030] As Figures 1 to 5 shown, the small hole 17 in the surface of the ear 16 is a threaded hole, so that the fastener such as a bolt or screw is directly screwed into the small hole 17 without the need for an additional nut or washer, thereby simplifying the installation process and improving the installation efficiency.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
