This fan is usually equipped with an adjustable bracket or base, and the user can adjust the fan angle according to their needs. This design can better meet the user's cooling needs in different scenarios. At the same time, this fan is also more flexible and has a wider range of applications.

[0003] When adjusting the angle of a traditional cooling fan, after the fan starts working, the vibration effect caused by the rotation of the fan will cause the cooling fan to not remain at the adjusted angle for a long time. This makes it impossible for the cooling fan to dissipate heat for a long time in the required area, thereby reducing the cooling effect of the cooling fan. Utility Model Content

[0004] The utility model aims to provide a cooling fan which can be adjusted at multiple angles, so as to solve the problem that when the traditional cooling fan mentioned in the above background technology is adjusted in angle, after the fan starts working, the vibration effect generated by the rotation of the fan will make the cooling fan unable to maintain the adjusted angle for a long time, so that the cooling fan cannot dissipate heat to the required area for a long time, thereby reducing the cooling effect of the cooling fan.

[0006] Preferably, the motor body can drive the fan blades to rotate, and the fan frame can slide and adjust the angle at the inner side of the mounting frame.

[0007] Preferably, the fan frame slides left and right along the slideway, and the fan frame rotates with the top insertion column and the bottom insertion column as the central axis when adjusting the angle.

[0008] Preferably, the top insertion column is inserted into an inner position of a convex threaded cap made of rubber material, and the convex threaded cap made of rubber material is fixed at an upper end position via a fixing column and a bottom insertion column so that the fan frame can slide.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 A multi-angle adjustable cooling fan is shown, comprising a mounting frame 1, wherein the front end of the mounting frame 1 is provided with through holes 4 at the four corners, the inner wall of the mounting frame 1 is provided with slideways 5 at the upper and lower positions, the mounting frame 1 is provided with a fan frame 8 that can slide left and right at the inner side of the mounting frame 1 through the slideway 5, the fan frame 8 is inserted into the inner side of the slideway 5 through a bottom insertion column 10 fixed at the lower end position for sliding, a motor body 6 is provided at the inner side of the fan frame 8, the motor body 6 can drive the fan blades 7 fixed at the outer wall position to rotate, the fan frame 8 is provided with a top insertion column 9 at the upper end position in a fixed manner, and the fan frame 8 is provided with a top insertion column 9 at the inner side of the fan frame 8. A convex threaded cap 3 made of rubber material is installed at the upper end of the fan frame 8. The convex threaded cap 3 made of rubber material wraps the top insertion column 9 at the inner position. A plurality of grooves 12 are arranged at the outer wall of the convex threaded cap 3 made of rubber material. A fixing column 11 fixed at the upper end of the convex threaded cap 3 made of rubber material is inserted into the inner side of the slideway 5. The threaded structure at the outer wall of the convex threaded cap 3 made of rubber material enables a bolt cap 2 to be installed at the outer wall of the convex threaded cap 3 made of rubber material. A slide groove 15 is arranged at the upper end of the bolt cap 2. A slidable connecting rod 13 is installed at both sides of the upper end of the bolt cap 2 through the slide groove 15. A rubber pad 14 is fixed at the upper end of the connecting rod 13.

[0023] The motor body 6 is connected to a power source so that it can drive the fan blades 7 to rotate. The rotation of the fan blades 7 generates airflow. The fan frame 8 is placed in an internal position of the device. The airflow generated by the rotation of the fan blades 7 can take away heat, thereby reducing the temperature of the device.

[0024] like Figure 1 and Figure 3 As shown, the motor body 6 can drive the fan blades 7 to rotate, the fan frame 8 can slide and adjust the angle at the inner side of the mounting frame 1, the fan frame 8 slides left and right along the slide 5, and the fan frame 8 rotates with the top insertion column 9 and the bottom insertion column 10 as the central axis when adjusting the angle, the top insertion column 9 is inserted into the inner position of the rubber material convex threaded cap 3, and the rubber material convex threaded cap 3 is fixed at the upper end position through the fixing column 11 and the bottom insertion column 10 so that the fan frame 8 can slide.

[0025] When the fan frame 8 is adjusted to a suitable angle, the bolt nut 2 on the outer wall of the rubber material convex threaded nut 3 is rotated. A plurality of grooves 12 are provided at the outer wall of the rubber material convex threaded nut 3. The bolt nut 2 is rotated on the outer wall of the rubber material convex threaded nut 3. When the bolt nut 2 is rotated from a thin area with the rubber material convex threaded nut 3 to a thick area, the rubber material convex threaded nut 3 is tightly fitted with the top insertion column 9. At the same time, the bolt nut 2 moves downward so that the rubber pad 14 is fitted on the inner wall of the slide 5. This prevents the fan frame 8 from moving and rotating, so that it remains at a specified angle.

[0026] like Figure 1 and Figure 4 As shown, a bolt nut 2 is installed at the outer wall of the rubber material convex threaded nut 3, and the through hole at the upper end of the bolt nut 2 allows the fixing column 11 to pass through. When the bolt nut 2 is rotated and moved downward, the inner wall of the rubber material convex threaded nut 3 can be tightly fitted with the outer wall of the top insertion column 9. The fit between the rubber material convex threaded nut 3 and the top insertion column 9 prevents the fan frame 8 from rotating. The rotation of the bolt nut 2 causes the connecting rod 13 to move along the slide groove 15. The bolt nut 2 moves downward so that the rubber pad 14 fits with the inner wall of the slide 5. The fit between the rubber pad 14 and the inner wall of the slide 5 stops the fan frame 8 from moving.

[0027] A slide groove 15 is provided at the upper end of the bolt cap 2. When the bolt cap 2 rotates on the outer wall of the rubber convex threaded cap 3 and moves downward, the connecting rod 13 moves at the inner position of the slide groove 15 along with the rotation of the bolt cap 2, so that the rubber pad 14 moves downward along with the bolt cap 2 until it fits with the inner wall of the slideway 5.
