[0002] A plastic square grille is a mesh grille made of plastic, usually with a square appearance. It is made by building a fine plastic grid or mesh into a square structure. This grille can be used to cover or protect a variety of equipment, areas or items.

[0003] The existing air conditioner outdoor unit is generally placed outdoors, and there will be a large amount of leaves, branches, dust and other debris outdoors. When a strong wind blows, these debris scattered on the ground will float with the wind and be easily sucked into the interior of the air conditioner outdoor unit by the action of the air conditioner outdoor unit, causing damage to the internal components. Therefore, it is necessary to provide a plastic square mesh cover on the outside of the air conditioner outdoor unit to isolate the impurities and protect the internal components from damage. Since the plastic mesh cover needs to be disassembled and cleaned regularly after long-term use, it can better protect the air conditioner outdoor unit. However, the current plastic square mesh cover adopts a bolt connection method, which requires carrying a screwdriver when disassembling and installing it, and due to high-altitude operations, cumbersome operations will greatly increase the safety hazards of the staff. For this reason, it is necessary to design a connection structure that can quickly disassemble the plastic square mesh cover. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the existing plastic square mesh cover is connected by bolts, which requires carrying a screwdriver for disassembly and installation, greatly increasing the work steps. The cumbersome disassembly and installation process increases the safety hazards of high-altitude operations. A plastic square mesh cover with a quick-release structure is provided.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plastic square mesh cover with a quick-release structure, comprising: a limiting mechanism, the limiting mechanism comprising a shell, a pressing plate is provided on the shell, a connecting plate is fixedly connected to the lower end of the pressing plate, two slots are provided on the connecting plate, a sleeve is fixedly connected to the lower end of the connecting plate, an annular array of installation grooves is provided on the outer wall of the sleeve, a steel ball is provided on one side of the installation groove, a limiting block is provided on the outer wall of the sleeve, and a spring is provided at the lower end of the inner wall of the sleeve.

[0006] As a preferred embodiment, the limiting mechanism is movably connected with an insert block inside, the outer wall of the insert block is provided with a connecting block, a connecting groove is opened on the connecting block, a slot hole is opened in the middle of the connecting block, and a mesh plate is fixedly connected to the outer wall of one side of the connecting block.

[0007] As a preferred implementation, the lower end of the limit block is fixedly connected to the inner wall of the lower end of the spring.

[0008] As a preferred embodiment, a connecting groove is provided on both sides of the slot hole opened in the middle of the connecting block.

[0009] As a preferred implementation, the inner wall of the limit block is movably connected with a sleeve shell.

[0010] As a preferred implementation, the steel ball is movably connected to the inner wall of the limiting block.

[0011] As a preferred implementation, an inner wall of the slot hole provided on the connecting block is movably connected to the inserting block.

[0012] As a preferred implementation, the connecting groove provided on the connecting block is movably connected to the pressing plate.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] The utility model is designed such that by pressing the pressing plate, the connecting plate will squeeze the casing downward and make it leave the connecting groove on the connecting block. The casing is subjected to a downward force, which will squeeze it downward and act on the spring. In this process, the steel balls in the mounting groove on the side wall of the casing will move downward as the external connection limit block tilts, causing the spacing between the steel balls to increase. This will enlarge the gap between the plug block and the connecting block, so that the plug block can be pulled out and detached from the slot on the connecting block, and then the mesh plate can be removed. Conversely, under the action of the spring, the casing will be pushed upward, driving the steel balls to move upward and making the gap smaller. In this way, the plug block will be clamped and will not cause the mesh plate to fall off. This operation is very simple and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the distance between the steel balls 67 will become larger, so that the gap connected with the plug block 5 will become larger, so that the plug block 5 can be pulled out, and then the mesh plate 1 can be removed. This operation is very convenient and improves work efficiency.

[0026] Example 2

[0028] In this example, a limiting mechanism 6 is designed, wherein the upper end of the limiting mechanism 6 is connected to a connecting block 2, and the upper end of the connecting block 2 is connected to an insert block 5, which can be connected to the limiting mechanism 6 through the insert block 5, and then the mesh plate 1 can be disassembled and installed, wherein a connecting block 2 is provided at each of the four corners of the mesh plate 1, and an insert block 5 and a limiting mechanism 6 are provided at the upper and lower ends of each connecting block 2, which can make the mesh plate 1 installed more firmly, and a connecting groove 3 and a slot hole 4 are provided on the connecting block 2, the connecting groove 3 is correspondingly connected to the limiting mechanism 6, and the slot hole 4 is correspondingly connected to the insert block 5, and the two interact with each other to complete the installation and disassembly of the mesh plate 1.

[0029] Working principle:

[0030] like Figure 1-4 As shown, when the utility model is in use, pressing the pressing plate 62 can drive the connecting plate 63 and squeeze the sleeve 65 downward and leave the connecting groove 3 opened in the connecting block 2. The sleeve 65 is subjected to the downward force and can be squeezed downward and act on the spring 69. At this time, the steel ball 67 provided on one side of the installation groove 66 opened in the side wall of the sleeve 65 is affected by the sleeve 65 and will move downward along the cross-sectional direction of the limit block 68 connected to the outside. At this time, the spacing between the steel balls 67 will become larger, so that the gap connected with the plug block 5 will become larger, so that the plug block 5 can be pulled out and separated from the slot 4 opened in the connecting block 2. At this time, the mesh plate 1 can be removed, and vice versa, it can be installed. Under the influence of the spring 69, the sleeve 65 will be pushed upward, and the steel ball 67 will be driven to move upward, and the gap will become smaller, and then the plug block 5 can be clamped, and the mesh plate 1 will not fall off. This operation is very convenient and improves work efficiency.
