[0030] like Figure 1-10 As shown, the 360-degree tilt structure of the fan of this utility model includes a base 1, with a first bracket 2 and a second bracket 3 fixedly connected to the left and right sides of the base 1, respectively. The first bracket 2 and the second bracket 3 are movably connected to the rear mesh cover 4.

[0031] The rear mesh cover 4 has a first fixing member 420 and a second fixing member 430 on each of its left and right sides of the rear mesh cover frame 410. The first fixing member 420 and the second fixing member 430 are symmetrical with respect to the central axis of the rear mesh cover 4. The first fixing member 420 has a protruding first fixing ring 421. The inner wall of the first fixing ring 421 is provided with a plurality of hollow cylinders, and the cylinders are provided with first screw holes 422.

[0032] The first fixing member 420 can be sleeved inside the first bracket 2. The first bracket 2 consists of a first bracket housing 220 and a first bracket cover 210, and the first bracket housing 220 is fixedly connected to the base 1. The first bracket column 220 is provided with several protruding positioning buckles, and the side wall of the first bracket cover 210 is provided with corresponding slots. The first bracket housing 220 and the first bracket cover 210 are connected by buckles.

[0033] The first support housing 220 has a first through hole 221, and the edge of the first through hole 221 is provided with several slots, three of which are provided in this utility model. The diameter of the first through hole 221 is larger than the outer diameter of the first fixing ring 421. The first fixing member 420 is sleeved in the through hole of the first support housing 220, and there is a gap between the outer wall of the first fixing member 420 and the inner wall of the first through hole 221 of the first support housing 220.

[0034] A connector 230 is disposed in the gap between the first fixing member 420 and the first through hole 221. The connector 230 is an injection-molded plastic part and includes a connector frame 231. The upper part of the connector frame 231 is a ring, and the lower part is a cuboid. One side of the connector frame 231 has a protruding connector collar 235 at the ring. The inner wall of the connector collar 235 also has a connector positioning post 236. The connector positioning post 236 engages in a groove on the edge of the first through hole 221, fixing the connector 230 in the first bracket housing 220 and preventing the connector 230 from rotating in the vertical direction. The cuboid part of the connector frame 231 has a protruding spring groove 232. A spring 233 is placed in the spring groove 232, and a stop bead 234 is placed on the upper end of the spring 233. Part of the stop bead 234 is inside the spring groove 232, and part of it protrudes from the spring groove 232. An observation window 237 is provided at the lower end of the spring groove 232 where it meets the frame 231 of the connector, for observing the state of the spring 233.

[0035] A rotating ring 240 is provided inside the annulus of the connecting frame 231. The rotating ring 240 includes a rotating frame 241, which is an annular structure with a circular inner ring and a sprocket tooth mechanism on the outer edge. The arc diameter of the tooth groove matches the diameter of the stop bead 234. The portion of the stop bead 234 protruding from the spring groove 232 can be located within the tooth groove of the rotating frame 241. When a rotational force is applied to the rotating ring 240, the stop bead 234 moves between the tooth grooves of the rotating frame 241. As the stop bead 234 gradually moves from the tooth groove of the sprocket tooth mechanism in the rotating frame 241 to the tooth tip, the tooth tip of the sprocket tooth mechanism exerts a downward force on the stop bead 234, pushing the cylinder 234 downward, thereby compressing the spring 233. When the rotating ring 240 loses the external force, the stop bead 234 moves under the thrust of the spring 233 to the nearest tooth groove in the rotating frame 241, and the rotating ring 240 stops rotating.

[0036] A stepped structure 242 is provided inside the rotating frame 241. The top surface of the stepped structure 242 is at the lower end of the rotating frame 241, and the bottom surface of the stepped structure 242 protrudes beyond the rotating frame 241. The outer diameter of the stepped structure 242 is smaller than the inner diameter of the annulus of the connecting frame 231. The part of the stepped structure 242 protruding beyond the rotating frame 241 is placed inside the annulus of the connecting frame 231, and the bottom surface of the stepped structure 242 is in contact with the top surface of the first fixing member 420. A rotating ring positioning hole 243 is provided on the stepped structure 242 at the position corresponding to the first screw hole 422 on the first fixing member 420. A fixing screw is installed in the rotating ring positioning hole 243 and inserted into the first screw hole 422 to fix the rotating ring 240 to the first fixing member 420. The outer dimension of the rotating frame 241 is larger than the inner diameter of the ring of the connecting frame 231. After the rotating ring 240 is fixedly connected to the first fixing member 420, the rotating frame 241 acts as a stop outside the ring of the connecting frame 231 to prevent the fan from swaying left and right when it is running.

[0037] A rotational force is applied to the fan in a vertical plane. The fan's rotation causes the first fixing member 420 on the rear grille frame 410 to rotate. The rotating ring 240 rotates in the vertical plane under the action of the first fixing member 420. The stop bead 234 compresses the spring 233, causing the stop bead 234 to be located in the spring groove 232. When the external force applied to the fan is stopped, the rotating ring 240 loses the external force. Under the upward elastic force of the spring 233, the stop bead 234 moves to the nearest tooth groove of the rotating frame 241, and the rotating ring 240 stops rotating. The fan is fixed in the direction when the external force is removed, thus realizing the rotation of the fan in the vertical plane.

[0038] A second fixing member 430 is provided on the right side of the rear mesh frame 410. The second fixing member 430 has a protruding second fixing ring 431. The inner wall of the second fixing ring 431 is provided with a number of hollow cylinders, and the cylinders are provided with second screw holes 432.

[0039] The second fastener 430 can be fitted into the second bracket 3. The second bracket 3 consists of a second bracket housing 320 and a second bracket cover 310. The second bracket housing 320 is fixedly connected to the base 1, just like the first bracket 2. The second bracket housing 320 and the second bracket cover 310 are connected by a snap fastener.

[0040] The second support housing 320 has a second through hole 321. The diameter of the second through hole 321 is larger than the outer diameter of the second fixing ring 431. The second fixing member 430 is sleeved in the through hole of the second support housing 320. There is a gap between the outer wall of the second fixing member 430 and the inner wall of the second through hole 321.

[0041] A connecting ring 330 is disposed in the gap between the outer wall of the second fixing member 430 and the inner wall of the second through hole 321. The connecting ring 330 includes a connecting ring base 331 and a collar 334 protruding below the bottom surface of the connecting ring base 331. The collar 334 is located between the second fixing member 430 and the second through hole 321. A connecting ring boss 332 is provided on the top surface of the connecting ring base 331. The bottom surface of the connecting ring boss 332 is in contact with the top surface of the second fixing member 430. A boss positioning hole 333 is provided on the connecting ring boss 332 corresponding to the second screw hole 432 of the second fixing member 430. A fixing screw is installed in the boss positioning hole 333 and inserted into the second screw hole 432 to fix the connecting ring 330 to the second fixing member 430. When the fan rotates, the second fixing member 430, which is fixed on the rear grille frame 410, rotates together, thereby driving the connecting ring 330 to rotate. The outer dimension of the connecting ring base 331 of the connecting ring 330 is larger than the diameter of the through hole of the second bracket housing 320. The connecting ring base 331 is on the second bracket housing 320 to prevent the fan from swaying left and right when it is running.

[0042] This utility model discloses a 360-degree tilting structure for a fan, which is easy to operate. The fan angle can be adjusted and fixed in 360 degrees simply by gently bending the fan head with your hand. In addition, the design structure of this utility model is simple and not prone to failure. The tilting structure of this utility model is mainly hidden in the bracket, which saves space and is also aesthetically pleasing.
