[0025] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 2 :

[0026] A mobile frame for a fan, comprising a horizontally arranged base frame 1, a plurality of universal wheels are arranged at the bottom of the base frame 1, two sets of vertical frame groups 2 with the same structure and arranged on the base frame 1 facing each other are arranged above the base frame 1, each set of vertical frame groups 2 comprises two parallel side rods 20 arranged longitudinally on the base frame 1, a mounting cross plate 21 is arranged between the tops of the two side rods 20, a fan 3 is arranged between the two mounting cross plates 21, the fan 3 comprises a cylindrical fan cover 30, the two sides of the fan cover 30 are connected to the mounting cross plates 21 on both sides by a movable hinge, and the mounting cross plates 21 are provided with The arc-shaped slide groove 22, and a locking pad 31 corresponding to the slide groove 22 is fixed on the side wall of the fan cover 30. When the fan cover 30 rotates along the hinge, the locking pad 31 moves along the length direction of the slide groove 22. A locking screw 4 is provided in the slide groove 22. The outer end of the locking screw 4 extends out of the slide groove 22 and is fixed with a hand wheel 40. The inner end of the locking screw 4 is threadedly connected with the locking pad 31. When the locking pad 31 slides to the required position corresponding to the slide groove 22 and the hand wheel 40 is rotated, the end of the hand wheel 40 abuts against the end face of the slide groove 22, and the fan cover 30 is no longer hinged and rotated along the hinge.

[0027] In the above implementation process, the fan placed on the base frame 1 can be moved by using the universal wheel; and when the fan angle is adjusted, the fan cover is hinged and rotated along the hinge position of the mounting horizontal plate 21. The locking effect is achieved by turning the hand wheel 40 so that the locking screw 4 controlled by the hand wheel is tightly matched with the locking pad 31. When tightly matched, one end face of the hand wheel is tightly matched with the end face of the mounting horizontal plate as the thread is tightened. After the tight match, the locking pad can no longer slide in the length direction of the corresponding slide groove due to the tight match, thereby effectively achieving locking.

[0028] In the above embodiment, fan components such as fan blades are arranged in the fan cover. Considering the wire connection, the actual rotation adjustment angle range should be within the length of the slide slot, and the entire rotation along the hinge cannot be performed to ensure that the wire will not be entangled.

[0029] Preferably, the number of the slide grooves 22 is two groups, and the two groups of slide grooves 22 are located on both sides of the hinge. When the fan cover 30 is rotated, the locking pads 31 corresponding to the two slide grooves 22 rotate clockwise or counterclockwise.

[0030] In the implementation process, the two sets of slide grooves 22 provide greater locking strength, and the two sets of slide grooves are on both sides of the hinge. If the hinge is not located in the middle of the two sets of slide grooves 22, the length of the slide groove farther from the hinge is longer than the length of the slide groove closer to the hinge, so that they can rotate synchronously to the same angle when rotating.

[0031] Preferably, a mounting base 32 is fixed on both sides of the fan cover 30, a hinge hole is opened on the mounting base 32, a hinge shaft 33 is hinged in the hinge hole, and both ends of the hinge shaft 33 are respectively fixed to the side wall of the fan cover 30 and the middle part of the mounting cross plate 21, and the locking pad 31 is fixedly connected to the outer wall of the mounting base 32.

[0032] In the above implementation process, considering that the fan cover has an arc-shaped surface, the actual locking pad 31 will not fit firmly with the fan cover surface. The provided mounting base plate 32 can ensure the stable setting of the hinged position while ensuring that it will not loosen during locking.

[0033] Preferably, the upper edge and the lower edge of the fan cover 30 both extend outward to form a mounting ring 34, and the two ends of the mounting base plate 32 are fixedly connected to the mounting rings 34 on both sides by bolts.

[0034] Preferably, a reinforcing rod 23 is fixed between the middle portion of the side rod 20 and the base frame 1 to enhance the structural strength.

[0035] Preferably, a horizontally placed tripod 10 is fixed to the front side of the base frame 1 , and a universal wheel is provided at the bottom of the tripod 10 .

[0036] Preferably, a pull rod 11 is hinged on the top of the tripod 10 , and a handle 12 is provided on the top of the pull rod 11 .

[0037] During the implementation process, the user can make certain steering movements through the universal wheels at the bottom of the tripod; the provided pull rod is convenient for the user to operate by hand, which brings convenience.

[0038] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
