Under the rotational connection between the rotating block 634 and the rotating groove 633, the U-shaped plate 2 can be rotated horizontally to adjust the angle of the large fan body 9. Under the elastic force of the spring 631, the block 632 and the rotating block 634 engage to complete the angle positioning, and the horizontal angle of the large fan body 9 can be adjusted to make its use effect better.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the positioning component 7 includes an end cap 71, a tension spring 72, a positioning rod 73 and a control block 74. The positioning rod 73 is embedded inside the U-shaped plate 2. The end cap 71 is connected to the side end of the positioning rod 73. The tension spring 72 on the side end of the end cap 71 is fitted with a tension spring 72. The control block 74 is connected to the surface of the positioning rod 73.

[0032] Specifically, the two ends of the tension spring 72 are connected to the end cap 71 and the U-shaped plate 2 respectively, and the control block 74 is located on the surface of the positioning rod 73 on the outside of the U-shaped plate 2.

[0033] By adopting the above technical solution, under the pulling force of the tension spring 72 on the surface of the U-shaped plate 2 on the end cap 71, the end cap 71 drives the positioning rod 73 to move outward and can be inserted into the adjustment plate 8 to complete the positioning.

The positioning rod 73 forms an integrated connection structure with the U-shaped plate 2 through the tension spring 72, which is simple to operate and prevents it from falling off.

[0034] In this embodiment, under the pulling force of the tension spring 72 on the surface of the U-shaped plate 2 on the end cap 71, the end cap 71 drives the positioning rod 73 to move outward and can be inserted into the adjustment plate 8 to complete the positioning. Pressing the control block 74 can separate the positioning rod 73 from the adjustment plate 8 for angle adjustment. The positioning rod 73 forms an integral connection structure with the U-shaped plate 2 through the tension spring 72, which is simple to operate and prevents it from falling off.

[0035] The structure and operating principle of the rotating shaft 1, U-shaped plate 2, heating mechanism 3, base 4, universal wheel 5, adjustment disc 8, and large fan body 9 in this utility model have been disclosed in Chinese patent application No. 201920565420.2, which discloses an industrial large fan with convenient angle adjustment. Its working principle is that the device can be moved in position by the universal wheel 5 at the bottom of the base 4. The large fan body 9 is installed inside the U-shaped plate 2 through the rotating shaft 1. The tilt angle of the large fan body 9 can be controlled and adjusted by the adjustment disc 8. The operation of the heating mechanism 3 can remove moisture from the air.

[0036] The working principle and usage process of this utility model are as follows: When in use, the device can be moved via the universal wheels 5 at the bottom of the base 4.
