[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 14The utility model provides a fan grille that is easy to assemble, including a rear grille 2 and a front grille 1. The rear grille 2 is connected to the front grille 1 by any one of a first connector, a second connector, and a third connector. The first connector includes a limiting rib 4, a paddle 3, and a connecting block 8. The limiting rib 4 is connected to the front grille 1, and the paddle 3 is movably connected to the rear grille 2. The paddle 3 is used to drive the connecting block 8 to move, and the connecting block 8 matches the limiting rib 4. The second connector includes a guide seat 11, a locking seat 13, a locking tongue 14, and a clamping head 15. The guide seat 11 is connected to the front grille 1, the locking seat 13 is connected to the rear grille 2, and the locking tongue 14 is liftable and connected to the guide seat 11, and the locking tongue 14 matches the clamping head 15. The third connector includes a positioning block 28 and a pressing block 25. The pressing block 25 is connected to the front grille 1, and the positioning block 28 is connected to the rear grille 2, and the positioning block 28 matches the pressing block 25.

[0030] Two connectors are provided, positioned relatively close to each other. They also include a friction surface 5, a guide block 7, and multiple anti-slip protrusions 6. The friction surface 5 is located on top of the limiting rib 4, the anti-slip protrusions 6 are connected to the outside of the paddle 3, and the guide block 7 guides the paddle 3. When the front grille 1 is connected to the rear grille 2, applying a thrust to the paddle 3 simultaneously drives the connector block 8 to move, pressing it against the limiting rib 4. The friction between the two creates upper and lower limits, ensuring the stability of the connection between the front grille 1 and the rear grille 2.

[0031] The friction surface 5 can increase the contact friction with the connecting block 8 to prevent slipping. The anti-slip protrusion 6 can increase the contact friction with the hand to facilitate the operation of the pick 3.

[0032] When the front mesh cover 1 and the rear mesh cover 2 need to be separated, the paddle 3 is pushed back with force to separate the connecting block 8 from the limiting rib 4, thereby loosening the front mesh cover 1 and facilitating the separation of the two.

[0033] The guide block 7 is fixedly connected to the paddle 3, and a sliding hole 9 is provided on the inner side of the rear mesh cover 2. The guide block 7 is slidably connected to the sliding hole 9. The guide block 7 slides in the sliding hole 9 to improve the stability of the reciprocating movement of the paddle 3, that is, the connecting block 8 moves stably and can be accurately docked with the limiting rib 4.

[0034] There are two connecting parts 2, and they are relatively distributed. The connecting part 2 also includes a pressing rod 10, a lifting plate 12, a slot 16, a lifting block 17, a spring 18, a spring column 19, an outlet surface 20, an inlet surface 21, a bevel block 22, a positioning head 23, a connecting shaft 24, and a spring 2 30. The pressing rod 10 is fixedly connected to the lifting plate 12, the lifting plate 12 is slidably connected to the guide seat 11, the lock tongue 14 is connected to the bottom of the lifting plate 12, the lifting block 17 is slidably connected to the lock seat 13, and the spring column 18 is connected to the lock seat 19. 9 is fixed to the bottom end of the lock seat 13, the two ends of the spring 18 are connected to the spring column 19 and the lifting block 17, the clamping head 15 is connected to the top of the lifting block 17, the connecting shaft 24 is connected to the lifting block 17 through the torsion spring, the positioning head 23 is connected to the connecting shaft 24, and the positioning head 23 matches the card slot 16, the card slot 16, the lead-out surface 20, and the lead-in surface 21 are set on the inclined block 22, the inclined block 22 is connected to the lock seat 13, and the two ends of the spring 2 30 are connected to the lifting plate 12 and the guide seat 11.

[0035] After the front mesh cover 1 is connected to the rear mesh cover 2, the pressing rod 10 is pushed downward with force, which can simultaneously drive the lifting plate 12 and the locking tongue 14 downward. At this time, the second spring 30 is gradually compressed, and the locking tongue 14 presses on the lifting block 17 and drives the lifting block 17 downward, and the first spring 18 is gradually compressed. At the same time, the positioning head 23 and the connecting shaft 24 also move downward synchronously. The positioning head 23 slides on the introduction surface 21, and the torsion spring is gradually retracted. After the lifting block 17 has dropped to an appropriate position, the positioning head 23 connects to the slot 16 to limit the lifting block 17. At this time, the clamping head 15 clamps to the locking tongue 14. In combination with the use of the second spring 30, the stability of the connection between the front mesh cover 1 and the rear mesh cover 2 can be improved.

[0036] When the front mesh cover 1 and the rear mesh cover 2 need to be separated, the pressing rod 10 is pushed down again with force, which can simultaneously drive the lifting block 17 to move further down. At this time, the positioning head 23 is separated from the slot 16, and the wound torsion spring drives the positioning head 23 to rotate a certain angle. Then the pressing rod 10 is released, and the compressed spring 18 can lift the lifting block 17, so that the positioning head 23 slides along the lead-out surface 20 until the positioning head 23 returns to its position. The clamping head 15 is in an open state, and the locking tongue 14 is separated from the clamping head 15, which facilitates the separation of the front mesh cover 1 and the rear mesh cover 2.

[0037] Both the lead-out surface 20 and the lead-in surface 21 are smooth surfaces, which can reduce the contact friction with the positioning head 23.

[0038] There are two connecting parts three, and they are relatively distributed. Connecting part three also includes a groove 26, a slope 27, and a positioning protrusion 29. The groove 26 matches the positioning protrusion 29, and the groove 26 is set on the clamping block 25. The positioning protrusion 29 is connected to the positioning block 28. The slope 27 is set at the end of the clamping block 25, and the clamping block 25 is an L-shaped structure.

[0039] After the front mesh cover 1 is connected to the rear mesh cover 2, the rotatable front mesh cover 1 can synchronously drive the two clamping blocks 25 to rotate, so that the clamping blocks 25 move toward the positioning blocks 28 of the rear mesh cover 2. The inclined surface 27 can facilitate the connection between the clamping blocks 25 and the positioning blocks 28 until the positioning protrusion 29 is connected to the groove 26. The front mesh cover 1 and the rear mesh cover 2 can be firmly connected to achieve a good limiting purpose.

[0040] When the front mesh cover 1 and the rear mesh cover 2 need to be separated, the front mesh cover 1 is rotated forcefully to separate the pressing block 25 from the positioning block 28, and the positioning protrusion 29 is separated from the groove 26 at the same time, thereby loosening the front mesh cover 1 and facilitating separation from the rear mesh cover 2. The operation is simple and convenient.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
