[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0018] 1. In the present utility model, by providing a hinge and a fixing component, the first grille and the second grille are unfolded, so that one side of the first grille and the second grille comes into contact, and the insertion plate provided on the side wall of the second grille is inserted into the inside of one side of the first grille. The first grille squeezes the push plate provided on the inner wall of the second grille, and the push plate simultaneously squeezes the second spring to form a compressed state. The push plate drives the positioning block to displace through the connecting rod, so that the positioning block is removed from the positioning groove provided on the side wall of the buckle block. At the same time, the elastic force generated by the third spring in the compressed state pushes the buckle block to displace, so that it drives the pin to insert into the pin hole provided on the insertion plate. When it is necessary to fold the first grille and the second grille, only need to pull the pull rod to remove the pin on the buckle block from the pin hole provided on the insertion plate. Through this design, it effectively realizes that the filter grille can be folded and unfolded at any time, greatly saving the space for transportation and storage, enabling more filter grilles to be stored in the existing space, and enabling multiple filter grilles to be carried during a single transportation, with good use effect.

[0019] 2. In the utility model, a snap-fit ​​assembly is provided, and when the first grille and the second grille are folded, the latch on the first grille is inserted into the latch hole provided on the second grille. Initially, the latch squeezes the fixed block provided on the side wall of the latch hole, and the fixed block squeezes the first spring through the sleeve to form a compressed state. When the hole provided on the side wall of the latch and the fixed block are on the same horizontal line, the elastic force of the first spring pushes the fixed block into the hole and overlaps with it. Since the fixed block position and the hole position are both spherical, and the friction coefficient between the fixed block position and the hole is small, when the filter grille needs to be unfolded, the staff only needs to hold one side of the first grille and the second grille and pry them apart. Through this design, the folded filter grille is effectively fixed so that it will not be unfolded during transportation, which greatly improves the stability of the filter grille after folding and has a good use effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1-4, the present utility model provides a technical solution: a foldable filter grille assembly, including a first grille 1, a hinge 3 is provided on the side wall of the first grille 1, a second grille 2 is provided on the outer wall of the hinge 3, a pin hole 5 is provided on the outer wall of the second grille 2, a snap component 4 is provided on the outer wall of the first grille 1, and a fixing component 6 is provided on the outer walls of the first grille 1 and the second grille 2;

[0028] The fixing component 6 includes a push plate 62 and a snap block 67. A first telescopic rod 65 is fixedly installed on the outer wall of the push plate 62, and the other end of the first telescopic rod 65 is fixedly installed on the inner wall of the first grille 1;

[0029] A second spring 66 is sleeved on the outer wall of the first telescopic rod 65. A connecting rod 63 is fixedly installed on the side wall of the push plate 62, and the other end of the connecting rod 63 is fixedly installed with a positioning block 64. A pin 68 is fixedly installed on one side of the snap block 67, and a second telescopic rod 610 is fixedly installed on the other side of the snap block 67. The other end of the second telescopic rod 610 is fixedly installed on the inner wall of the first grille 1. A third spring 611 is sleeved on the outer wall of the second telescopic rod 610. A pull rod 69 is fixedly installed on the outer wall of the middle end of the snap block 67. The pull rod 69 penetrates through a through hole provided on the outer wall of the first grille 1. An insertion plate 61 is fixedly installed on the side wall of the second grille 2, and a pin hole is provided on the outer wall of the insertion plate 61;

[0030] The specific implementation method is as follows: The first grille 1 and the second grille 2 are unfolded so that one side of the first grille 1 and the second grille 2 are in contact. The insertion plate 61 provided on the side wall of the second grille 2 is inserted into the inside of one side of the first grille 1. The first grille 1 presses the push plate 62 provided on the inner wall of the second grille 2. The push plate 62 simultaneously presses the second spring 66 to form a compressed state. The push plate 62 drives the positioning block 64 to displace through the connecting rod 63, so that the positioning block 64 is removed from the positioning groove provided on the side wall of the snap block 67. At the same time, the elastic force generated by the third spring 611 in the compressed state pushes the snap block 67 to displace, so that it drives the pin 68 to insert into the pin hole provided on the insertion plate 61. When it is necessary to fold the first grille 1 and the second grille, only need to pull the pull rod 69 to move the pin 68 on the snap block 67 out of the pin hole provided on the insertion plate 61.

[0031] The snap component 4 includes a plug pin 41 and a fixing block 42. The plug pin 41 is fixedly installed on the outer wall of the first grille 1. A sleeve 43 is fixedly installed on the outer wall of the fixing block 42. A first spring 44 is fixedly installed on the inner wall of the sleeve 43, and the other end of the first spring 44 is fixedly installed on the inner wall of the installation groove provided on the side wall of the pin hole 5;

[0032] The specific implementation method is as follows: when the first grille 1 and the second grille 2 are folded, the latch 41 on the first grille 1 is inserted into the latch hole 5 set on the second grille 2. Initially, the latch 41 squeezes the fixed block 42 set on the side wall of the latch hole 5, and the fixed block 42 squeezes the first spring 44 through the sleeve 43 to form a compressed state. When the hole set on the side wall of the latch 41 and the fixed block 42 are on the same horizontal line, the elastic force of the first spring 44 pushes the fixed block 42 into the hole and overlaps with it. Since the fixed block 42 and the hole are both spherical, and the friction coefficient between the fixed block 42 and the hole is small, when the filter grille needs to be unfolded, the staff only needs to hold one side of the first grille 1 and the second grille 2 and pry them apart.

[0033] Working principle: the first grille 1 and the second grille 2 are unfolded, so that the first grille 1 contacts one side of the second grille 2, and the plug plate 61 provided on the side wall of the second grille 2 is inserted into the inside of one side of the first grille 1, and the first grille 1 squeezes the push plate 62 provided on the inner wall of the second grille 2, and the push plate 62 squeezes the second spring 66 at the same time, so that it forms a compressed state, and the push plate 62 drives the positioning block 64 to move through the connecting rod 63, so that the positioning block 64 is removed from the positioning groove provided on the side wall of the buckle block 67, and at the same time, the elastic force generated by the third spring 611 in the compressed state pushes the buckle block 67 to move, so that it drives the bayonet 68 to insert into the bayonet hole provided on the plug plate 61. When the first grille 1 and the second grille need to be folded, only the pull rod 69 needs to be pulled to move the bayonet on the buckle block 67. 68 can be moved out from the pin hole set on the plug plate 61. When the first grille 1 and the second grille 2 are folded, the pin 41 on the first grille 1 is inserted into the pin hole 5 set on the second grille 2. Initially, the pin 41 squeezes the fixed block 42 set on the side wall of the pin hole 5, and the fixed block 42 squeezes the first spring 44 through the sleeve 43 to form a compressed state. When the hole set on the side wall of the pin 41 and the fixed block 42 are on the same horizontal line, the elastic force of the first spring 44 pushes the fixed block 42 into the hole and overlaps with it. Because the fixed block 42 and the hole are both spherical, and the friction coefficient between the fixed block 42 and the hole is small, when the filter grille needs to be unfolded, the staff only needs to hold one side of the first grille 1 and the second grille 2 to pry them apart.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
