[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Examples, such as Figures 1-4 As shown: This utility model provides a mesh door composite metal door assembly, the structure of which includes a door frame 1 and a door leaf 2 installed on the door frame 1. The outer side of the door frame 1 is provided with a side cavity 1b, which is used to fit the door leaf 2 into the wall when it is installed. The top and bottom ends of the door frame 1 are provided with guide rails 1a. A folding door assembly 3 is provided inside the door frame 1 along the guide rails 1a. A first lock 4 is provided on the folding door assembly 3. After the folding door assembly 3 is unfolded, the first lock 4 is engaged with the door frame 1, so that the folding door assembly 3 surrounds the door frame 1. The first lock 4 adopts a common folding door lock, such as the KNN brand YL201 sliding door lock. As long as a latch structure that engages with the door leaf is provided on the side of the end plate 31 near the door frame 1, those skilled in the art can choose according to actual needs.

[0024] The folding door assembly 3 includes a first mesh panel 32, a second mesh panel 33, and an end plate 31 that are movably connected. The first mesh panel 32 and the second mesh panel 33 are provided in a plurality of spaced arrangement. The top and bottom ends of the end plate 31 are slidably engaged with the guide rail 1a. The first lock 4 is installed on the end plate 31. The first mesh panel 32 and the second mesh panel 33 are provided with a plurality of through holes formed by the mesh of the mesh. The guide rail 1a is provided with an inner guide groove 1d. The first mesh panel 32 is provided with a follower pin 32a, which is slidably engaged in the inner guide groove 1d. The first mesh panel 32 and the second mesh panel 33 are flexibly connected by a connecting piece 34. When the end plate 31 is pulled to unfold, the folded first mesh panel 32 and the second mesh panel 33 are mutually driven to unfold through the connecting piece 34. The unfolded first mesh panel 32 and the second mesh panel 33 form an integral enclosure within the door frame 1 through the connecting piece 34 and are ventilated by the first mesh panel 32 and the second mesh panel 33.

[0025] In this embodiment, the inner side of the door frame 1 is provided with a storage compartment 1c that is recessed to the outer side of the door frame 1, and the guide rail 1a is set into the storage compartment 1c. The storage compartment 1c is used for folding and storing the folding door assembly 3.

[0026] In this embodiment, elastic components 35 are provided at the top and bottom of the connection between the first mesh plate 32 and the second mesh plate 33. The elastic components 35 provide elasticity for the first mesh plate 32 and the second mesh plate 33 to unfold in a folded state and fold in an unfolded state. Specifically, the elastic components 35 include an outer elastic bend 351 and an inner elastic bend 352, which are bent. The outer elastic bend 351 and the inner elastic bend 352 are made of metal, such as iron sheets. The outer elastic bend 351 and the inner elastic bend 352 are respectively located on the outer and inner sides of the connection between the folded first mesh plate 32 and the second mesh plate 33, and are connected to the connecting piece 34. Thus, the outer elastic bend 351 and the inner elastic bend 352... Both 352 provide elasticity for unfolding and folding. The outer spring bend 351 is mainly used to provide elasticity to drive the first mesh plate 32 and the second mesh plate 33 to fold in the unfolded state, while the inner spring bend 352 is mainly used to provide elasticity to drive the first mesh plate 32 and the second mesh plate 33 to unfold in the folded state. This facilitates the opening of the folding door assembly 3 when locked with the door frame 1. Furthermore, the elastic component 35 is installed at the connection between the end of the first mesh plate 32 with the follower pin 32a and the second mesh plate 33. When opened, the elastic component 35 drives the folding door assembly 3 to fold to a certain extent. The elasticity of the inner spring bend 352 is less than that of the outer spring bend 351, which makes it easier for the user to push the folding door further to store it in the storage compartment 1c.

[0027] Meanwhile, the end plate 31 is also provided with a second lock 5, which is used to lock and cooperate with the opening of the storage compartment 1c, so that the folding door assembly 3 can overcome the elastic force of the elastic component 35 and be folded and stored in the storage compartment 1c.

[0028] For this purpose, the inner side of the end plate 31 is provided with a sliding groove 31a. The second lock 5 includes a magnetic sliding block 53. The head of the magnetic sliding block 53 is magnetic. The magnetic sliding block 53 is movably installed in the sliding groove 31a. The sliding groove 31a has an opening on the end plate 31 and points towards the inner wall of the storage compartment 1c. The inner wall of the storage compartment 1c is provided with a limiting groove 1e. The magnetic sliding block 53 is attracted to the inner wall of the limiting groove 1e to limit the position of the end plate 31 and the storage compartment 1c. The outer side of the end plate 31 is provided with a hand inlet groove 31b for the user's fingertips to be inserted. The inner side of the end plate 31 is provided with a linkage groove 31c for connecting the sliding groove 31a and the hand inlet groove 31b. The second lock 5 also includes a pull plate 51 and a transmission plate 52. The moving part 52 and the hand pull plate 51 are oscillatingly connected in the hand inlet groove 31b. The transmission part 52 is slidably set in the linkage groove 31c and is connected to the hand pull plate 51 for transmission. A spring 54 is provided between the transmission part 52 and the linkage groove 31c to drive the transmission part 52 away from the magnetic slide 53. When the user manually pulls the hand pull plate 51 to swing it outward, the transmission part 52 will abut against the magnetic slide 53. The magnetic slide 53 has an inclined groove 53a on its inner side. The transmission part 52 has an inclined head 52a at its front end. The transmission part 52 abuts against the inclined groove 53a of the magnetic slide 53 through the inclined head 52a. The inclined head 52a and the inclined groove 53a abut against each other to drive the magnetic slide 53 to move in the direction of disengaging from the limiting groove 1e.

[0029] It should be noted that the head of the magnetic slide 53 may be magnetically attached to half of its end face, that is, magnetically attached to the side away from the door frame 1. This allows it to be attracted to the end plate 31 when it is stored in the slide groove 31a. However, when the end plate 31 is close to the door frame 1, the magnetic slide 53 will not be attracted to the door frame 1 immediately. Instead, the rear half of the head of the magnetic slide 53 will be attracted to the door frame 1 only after the end plate 31 has been inserted further.

[0030] In summary, during implementation, the door leaf 2 is opened, and the unfolded first mesh panel 32 and second mesh panel 33 surround the door frame 1 for ventilation. When it needs to be opened, the first lock 4 is unlocked, and the outer spring tab 351 drives the first mesh panel 32 and second mesh panel 33 to fold. The bent outer spring tab 351 applies the main elastic force to move the end plate 31 to the middle area of ​​the door frame 1. Then, the user pushes the end plate 31 to push it into the storage compartment 1c. When the magnetic slide 53 approaches the limiting groove 1e, it adheres to the door frame 1. After being pushed further inward, the magnetic slide 53 slides into the limiting groove 1e while adhering to it, and adheres to the inner wall of the limiting groove 1e to restrict the position of the end plate 31 and the storage compartment 1c, so that the folding door assembly 3 can be stored in the storage compartment 1c, avoiding obstruction to the user in the same space of the door.

[0031] When the folding door assembly 3 needs to be closed, the user inserts their fingertips into the hand slot 31b and pulls the pull plate 51 outward. The pull plate 51 swings, causing the inner side of the pull plate 51 to drive the transmission component 52 to slide towards the magnetic slide 53. The inclined head 52a abuts against the inclined groove 53a, causing the magnetic slide 53 to move in the direction of disengaging from the limiting groove 1e, so that the magnetic slide 53 is stored in the sliding groove 31a. Then, the inner spring bending piece 352 drives the first mesh plate 32 and the second mesh plate 33 to unfold in the folded state, making it convenient for the user to pull the end plate 31 close to the door frame 1 to lock.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
