Description

Technical Field

[0001] This utility model relates to the field of mesh covers, and in particular to a novel ventilation mesh cover. Background Technology

[0002] Ventilation mesh covers are made of low-carbon steel wire, stainless steel wire, etc., through processes such as bending, precision welding and grinding. Ventilation mesh covers serve two purposes: protection and preliminary filtration, preventing excessively large foreign objects from entering the interior of the container.

[0003] Currently, ventilation screens are mostly installed using bolts, which requires tools for both installation and removal, making it inconvenient.

[0004] Therefore, it is necessary to invent a new type of ventilation and air exchange mesh cover to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a novel ventilation and air exchange mesh cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel ventilation mesh cover, comprising a mounting base, a ventilation opening inside the mounting base, a mesh frame inside the ventilation opening, a mesh cover connected inside the mesh frame, grooves around the ventilation opening, springs connected inside the grooves, a connecting plate connected to the other end of the springs, a rod connected to the side wall of the connecting plate, slots corresponding to the rods around the mesh frame, a sealing plate connected to the other side of the connecting plate, a pull rod connected to the side wall of the sealing plate, a strip-shaped opening corresponding to the pull rod on the front side of the mounting base, multiple arc-shaped limiting frames connected to the front side of the mounting base, rotating rings inside the multiple arc-shaped limiting frames, push rods connected to the outer sides of the rotating rings, and the other end of the push rods connected to the side wall of the pull rods.

[0007] Preferably, a central reinforcing member is provided at the center of the mesh cover, and a handle is connected to the front side of the central reinforcing member.

[0008] Preferably, positioning blocks are connected to all four sides of the mesh frame, and positioning grooves corresponding to the positioning blocks are opened around all four sides of the ventilation opening.

[0009] Preferably, the front side of the rotating ring is fixedly connected to two symmetrically distributed actuating rods.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By rotating the rotating ring, the rotating ring pushes the push rod, which in turn pushes the pull rod to slide within the slot. The pull rod pulls the sealing plate, which in turn pulls the connecting plate. The connecting plate compresses the spring and pulls the insert rod, installing the mesh frame inside the vent. Releasing the rotating ring allows the spring force to insert the insert rod into the slot on the mesh frame for installation. Conversely, removing the insert rod from the slot and pulling the mesh cover allows for easy disassembly and assembly. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figure 1-3The novel ventilation mesh cover shown includes a mounting base 1, with a ventilation opening inside the mounting base 1. A mesh frame 2 is installed inside the ventilation opening, and a mesh cover 3 is connected inside the mesh frame 2. Grooves 4 are formed around the ventilation opening, and springs 5 ​​are connected inside the grooves 4. A connecting plate 6 is connected to the other end of the springs 5. Insert rods 7 are connected to the side wall of the connecting plate 6. Slots corresponding to the insert rods 7 are formed around the mesh frame 2. A sealing plate 8 is connected to the other side of the connecting plate 6, and a pull rod 9 is connected to the side wall of the sealing plate 8. A strip-shaped opening corresponding to the pull rod 9 is formed on the front side of the mounting base 1. Multiple arc-shaped limiting brackets 10 are connected to the front side of the mounting base 1, and rotating rings 11 are set inside the multiple arc-shaped limiting brackets 10. Push rods 12 are connected to the outer sides of the rotating ring 11. The other end of the push rod 12 is connected to the side wall of the pull rod 9. By rotating the rotating ring 11, the rotating ring 11 pushes the push rod 12, and the push rod 12 pushes the pull rod 9, so that the pull rod 9 slides in the strip-shaped opening. The pull rod 9 pulls the sealing plate 8, the sealing plate 8 pulls the connecting plate 6, the connecting plate 6 squeezes the spring 5, and pulls the insertion rod 7 to install the mesh frame 2 in the ventilation opening. When the rotating ring 11 is released, the spring force of the spring 5 allows the insertion rod 7 to extend into the slot on the mesh frame 2 to install the mesh cover 3. Conversely, the insertion rod 7 can be removed from the slot, and the mesh cover 3 can be removed by pulling it, which makes it easy to install and remove the mesh cover 3.

[0018] A central reinforcing member 13 is provided at the center of the mesh cover 3, and a handle 14 is connected to the front side of the central reinforcing member 13.

[0019] Positioning blocks 15 are connected to all four sides of the mesh frame 2. Positioning slots corresponding to the positioning blocks 15 are opened around the ventilation openings, which can facilitate the positioning of the mesh frame 2, thereby positioning the insertion rod 7 and the slot.

[0020] Two symmetrically distributed levers 16 are fixedly connected to the front side of the rotating ring 11. The levers 16 can be pulled by either the left or right hand. The rotating ring 11 is pulled down by the right hand and pulled up by the left hand, which can complete the disassembly and assembly of the mesh cover 3.

[0021] Working principle of this utility model:

[0022] By rotating the rotating ring 11, the rotating ring 11 pushes the push rod 12, and the push rod 12 pushes the pull rod 9, causing the pull rod 9 to slide in the slot. The pull rod 9 pulls the sealing plate 8, the sealing plate 8 pulls the connecting plate 6, the connecting plate 6 compresses the spring 5, and pulls the insertion rod 7, installing the mesh frame 2 in the ventilation opening. Releasing the rotating ring 11 allows the insertion rod 7 to extend into the slot on the mesh frame 2 through the elastic force of the spring 5, installing the mesh cover 3. Conversely, removing the insertion rod 7 from the slot and pulling the mesh cover 3 allows for its disassembly. The lever 16 can be pulled with either the left or right hand. The right hand pulls the rotating ring 11 downwards, and the left hand pulls the rotating ring 11 upwards, both methods completing the installation and disassembly of the mesh cover 3.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
