Description

All-round removable ceiling fan

technical field

The utility model relates to the field of electric fans, in particular to a suspension type electric fan for indoor ceilings in large spaces, especially an omnidirectional movable ceiling fan.

Background technique

For indoor cooling systems in large spaces such as workshops and classrooms, the effective range of traditional ceiling-suspended electric fans is limited to just below the ceiling fan and within the projected circle. Taking the center directly below the center of the ceiling fan as the center, the wind speed at different radius positions on the same horizontal plane is very different: the air volume at the center of the circle is the largest, and the cooling effect is the best; the larger the radius, the smaller the air volume. For ceiling fans commonly used in production and life, the cooling effect can hardly be felt beyond a radius of 3 to 5 meters. Two or more ceiling fans are often installed in large open spaces. However, its effect is limited, and it still cannot meet the cooling requirements of all or most of the indoor spaces during use. Needs to be improved.

Above-mentioned purpose of the utility model is realized through the following technical solutions:

The all-round movable ceiling fan includes the blade 1 and the connecting rocker 2, the connecting rocker 2 is connected with the crank rocker mechanism 3, the crank 3.1 of the crank rocker mechanism 3 is connected with the motor I4 and the connecting rod 3.2 respectively, and the motor Ⅰ4 drives the crank 3.1 to rotate, and the connecting rod 3.2 drives the connecting rocker 2 to swing at a certain angle; the crank rocker mechanism 3 and the motor Ⅰ4 are placed in the box body 5, and the box body 5 and the box body cover 6 are fixedly connected together , the box body cover 6 is respectively connected with the sliders I, II 8.1, 8.2 of the linear guide rail pair 8 and the connecting plate 9 through the screws 7, and the connecting plate 9 is connected with the nut 10.1 of the lead screw nut pair 10 through the screws 7. Together, one end of the screw nut pair 10 is connected to the motor II 12 through a coupling 11, and at the same time, the two ends of the screw 10.2 of the screw nut pair 10 are respectively connected to the bearing housing 14 through the bearing 13; the guide rail of the linear guide rail pair 8 Ⅰ, Ⅱ 8.3, 8.4, bearing housing 14 and motor Ⅱ 12 are fixed on the top plate 15.

The motor II 12 drives the lead screw 10.2 of the lead screw nut pair 10 to rotate through the coupling 11, and the nut 10.1 of the lead screw nut pair 10 is driven by the connecting plate 9 and welded together with the box body cover 6, and includes a crank rocker mechanism The box body 5 of 3 slides along the guide rails I, II 8.3, 8.4 through the slide blocks I, II 8.1, 8.2 of the linear guide rail pair 8 to realize the movement of the ceiling fan.

The beneficial effects of the utility model are that the structure is simple, the concept is novel, and the use is convenient. The motor I in the box body drives the crank rocker mechanism to rotate around the box body, so that the ceiling fan can swing at a certain angle on a position of the guide rail to increase the blowing area. The motor II fixed on the top plate drives the lead screw of the screw nut pair to rotate, so that the connecting plate connected with the nut pair drives the ceiling fan below the box body to move on the linear guide rail pair, not only through the slide on the linear guide rail pair The block stabilizes the ceiling fan, and the ceiling fan can also be moved to different positions, which can meet the needs of multiple people. Controlling the motor connected with the lead screw through the coupling can realize the stable stop of the ceiling fan at any position of the guide rail pair according to the user's needs, satisfying the use of a small number of and a single user. Strong practicality.
