[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] like Figure 1 As shown, a replaceable municipal dust control net according to this application includes a frame 1, a net body 2, multiple connectors 3, multiple guide blocks 4, and limiting protrusions 5. The frame 1, as the supporting frame of the entire structure, is usually made of metal or high-strength plastic material, and has an internal mounting position for fixing the net body 2. It is detachably connected to the net body 2 by threaded engagement with the connectors 3.

[0023] The mesh 2 is located inside the frame 1 and connected to the frame 1. It is usually made of mesh fabric or woven plastic fiber and has good shielding and dustproofing effects. During installation, the mesh 2 needs to be aligned with the frame 1 and fixed to the frame 1 by the connector 3 to ensure the stability and tightness of the overall structure.

[0024] Multiple connectors 3 are disposed between the frame 1 and the mesh body 2 to achieve a detachable connection between the frame 1 and the mesh body 2. One end of each connector 3 is embedded into the frame 1 and screwed into the frame 1 structure by threads, while the other end is fastened to the edge of the mesh body 2 by a locking groove 33, so that the mesh body 2 can be firmly fixed to the frame 1, and at the same time, it is convenient for later replacement and maintenance.

[0025] Multiple guide blocks 4 are fixedly installed on the inner edge of the frame 1. Their function is to guide and position the mesh 2, so that the mesh 2 can accurately enter the interior of the frame 1 during installation, avoiding offset or misalignment during installation. These guide blocks 4 are usually evenly distributed around the frame 1 and are correspondingly set with the connectors 3 to assist in the overall positioning of the mesh 2.

[0026] The limiting protrusion 5 is located at the end of the connector 3. Its design shape cooperates with the guide block 4 to limit the installation position of the mesh body 2 and prevent the structure from loosening or failing due to improper installation. During installation, the limiting protrusion 5 will insert into the reserved hole in the guide block 4 to limit and fix it, thereby improving the stability of the entire structure after installation.

[0027] This utility model achieves its effect through the cooperation between the guide block 4 and the limiting protrusion 5, as well as the design of the positioning hole 32, the insert section 31, and the engaging groove 33 on the connector 3 (see details). Figure 2 This design effectively solves the technical problems of poor centering and insufficient stability during installation. The guide block 4 ensures that the net body 2 is automatically guided to the correct position during installation, while the limiting protrusion 5 locks the net body 2 in place, forming a dual positioning mechanism. This structure not only improves the convenience of installation but also ensures overall stability after installation, reducing performance degradation or structural deformation caused by improper installation.

[0028] like Figure 1 As shown, in one embodiment, the frame 1 of the easily replaceable municipal dustproof netting of this application is a rectangular frame structure, with reinforcing blocks 6 at its four corners. The reinforcing blocks 6 are integrally formed with the frame 1, making the frame 1 less prone to deformation under external forces. This structural design effectively enhances the overall structural strength of the frame 1 and improves the durability of the dustproof netting, making it particularly suitable for applications exposed to outdoor environments for extended periods. The arrangement of the reinforcing blocks 6 helps reduce material consumption while improving assembly stability.

[0029] Specifically, the four corners of the frame 1 are molded into reinforcing blocks 6 that are integrally formed with the main body of the frame 1, making them structurally connected and thus ensuring the stability of the overall frame under stress. This one-piece molding process can effectively avoid structural weaknesses caused by traditional welding or riveting methods.

[0030] like Figure 3As shown, in one embodiment, the inner edge of the frame 1 of a replaceable municipal dustproof net of this application is provided with a groove 7. The groove 7 is used to accommodate the guide block 4, and the guide block 4 is fixed to the frame 1 by screws 8, ensuring that the guide block 4 maintains a stable position during installation. After the guide block 4 is embedded in the groove 7, it forms a solid connection with the frame 1, preventing displacement or loosening during use. This design can improve the reliability of the connection between the guide block 4 and the frame 1, while facilitating later maintenance and replacement.

[0031] Specifically, a groove 7 with a matching shape is machined on the inner edge of the frame 1. After the guide block 4 is inserted into the groove 7, it is fixed by a screw 8 that passes through the frame 1, so that the guide block 4 and the frame 1 form a rigid connection. The screw 8 passes through the preset hole on the frame 1 and is screwed into the corresponding threaded hole of the guide block 4 to achieve the fixing function, thereby ensuring that the guide block 4 is always in the correct position during the installation process.

[0032] like Figure 5 As shown, in one embodiment, the connector 3 of the easily replaceable municipal dustproof net of this application has a plurality of external threads 11 for engaging with the internal threads 10 inside the frame 1. This design allows the connector 3 to achieve a stable connection with the frame 1 by rotation, improving the stability during installation and facilitating quick disassembly and replacement during subsequent maintenance. The embedded section 31 is located at one end of the connector 3 near the frame 1, forming a threaded connection with the internal threads 10 inside the frame 1, thereby enhancing the overall strength of the connection.

[0033] For example, the connector 3 is inserted into the frame 1 through the external thread 11 and the internal thread 10 inside the frame 1. During installation, the insert 31 is screwed into the frame 1 until it reaches the predetermined position, so that the connector 3 is firmly fixed on the frame 1, thereby realizing the detachable connection between the frame 1 and the mesh 2.

[0034] like Figure 3 and Figure 5 As shown, in one embodiment, the locking groove 33 of the easily replaceable municipal dustproof net of this application is a T-shaped groove structure. The edge of the net body 2 is provided with a T-shaped locking block 13 that matches the T-shaped groove, thereby achieving a more stable locking connection. The locking groove 33 is formed at the end of the connector 3 away from the frame 1, and cooperates with the edge of the net body 2 to provide a stable connection force during installation and ensure that the net body 2 is not easily detached when subjected to external forces. This design can improve the stability during disassembly and assembly, while simplifying the operation steps and improving the ease of use.

[0035] For example, the T-shaped locking block 13 can be set at a corresponding position on the edge of the mesh body 2 and match the T-shaped engaging groove 33 on the connector 3. The mesh body 2 is fixedly connected by snapping it in, making the installation of the mesh body 2 within the frame 1 more secure and reliable. The engaging groove 33 and the T-shaped locking block 13 have a certain embedding depth to ensure the structural stability after connection.

[0036] like Figure 2 and Figure 5 As shown, in one embodiment, a spring 12 is provided at one end of the limiting protrusion 5 of a municipal dustproof net that is easy to disassemble. The spring 12 enables the limiting protrusion 5 to move, thereby facilitating separation from the positioning hole 32 and releasing the net body 2 from fixation. The limiting protrusion 5 is located at the end of the connector 3 and cooperates with the guide block 4 to limit the installation position of the net body 2. The spring 12 is arranged on the side of the limiting protrusion 5 near the connector 3, and its elasticity enables the limiting protrusion 5 to rebound and shift, thereby adapting to the needs of different installation states. The spring 12 allows the limiting protrusion 5 to disengage from the positioning hole 32 under external force, improving the ease of disassembly.

[0037] Specifically, the end of the connector 3 is provided with a channel through which the limiting protrusion 5 passes. A mounting groove for supporting the spring 12 is provided within this channel. The limiting protrusion 5 passes through this groove and is connected to the spring 12. When an external pulling force is applied, the limiting protrusion 5 retracts backward along the channel and compresses the spring 12, causing it to disengage from the positioning hole 32, thus completing the fixation release operation. When the external force is removed, the spring 12 rebounds, pushing the limiting protrusion 5 back to its original position and re-embedding into the positioning hole 32 to achieve fixation.

[0038] like Figure 2 and Figure 4 As shown, in one embodiment, the guide block 4 of the easily replaceable municipal dust control net of this application has an L-shaped structure, and a guide groove 14 matching the L-shaped guide block 4 is provided on the outer edge of the net body 2. The design of the guide groove 14 allows the net body 2 to slide along the guide block 4 and automatically center itself during installation, improving the accuracy and stability of installation. The guide block 4 is fixedly installed on the inner edge of the frame 1, and through its cooperation with the guide groove 14, it limits the position of the net body 2, preventing offset during installation. This structure helps to improve the overall efficiency of the dust control net and simplifies the disassembly and assembly process.

[0039] For example, the guide block 4 is L-shaped, with one end fixedly connected to the inner side of the frame 1 and the other end extending to the inner edge of the frame 1. The outer edge of the mesh body 2 is provided with a longitudinal or transverse guide groove 14 that is adapted to it. The guide groove 14 is opened on the inner side of the edge of the mesh body 2, so that the guide block 4 can be embedded in it and slide along it, thereby ensuring that the mesh body 2 is accurately positioned during installation.

[0040] like Figure 4 As shown, in one embodiment, a buffer pad 15 is provided between the guide block 4 and the frame 1 of the easily replaceable municipal dustproof net of this application to reduce the impact during installation and protect the frame 1. The buffer pad 15 is located at the contact point between the guide block 4 and the frame 1, serving as a buffer and isolation layer to prevent structural damage caused by mechanical impact. This design effectively reduces the risk of deformation due to external forces during installation and improves the overall structural stability. Simultaneously, the use of the buffer pad 15 also extends the service life of the dustproof net, ensuring that the structural performance remains good after multiple disassemblies and reassemblies.

[0041] Specifically, the buffer pad 15 can be made of rubber or silicone material, with one end conforming to the surface of the guide block 4 and the other end abutting the inner edge of the frame 1 to form a tight fit. The pad is fixed between the guide block 4 and the frame 1 by direct bonding or snap-fit, realizing an elastic connection between the two, thereby absorbing some kinetic energy during installation and reducing stress concentration on the frame 1.

[0042] like Figure 5 As shown, in one embodiment, a limiting protrusion 5 of a municipal dust control net, which is easy to replace, is provided with a lever 9 on one side wall. One end of the lever 9 protrudes from the connector 3. This design is intended to facilitate the application of external force to the limiting protrusion 5 to cause it to deform or move. The lever 9 effectively improves the ease of operation of the limiting protrusion 5, making it easier and more precise for workers to install or remove the dust control net. The limiting protrusion 5, in conjunction with the guide block 4, limits the installation position of the net body 2, while the lever 9 engages with the limiting protrusion 5 to form a linkage structure, ensuring that the limiting protrusion 5 can be smoothly triggered during operation. The lever 9 is usually embedded in the side wall of the connector 3, with only one end exposed, ensuring the overall structural stability and safety.

[0043] Specifically, the lever 9 is located on the side of the limiting protrusion 5 near the connector 3. The lever 9 is integrally formed onto the side wall of the connector 3 using a molding process, ensuring a stable connection between the limiting protrusion 5 and the lever 9. Simultaneously, the lever 9 can withstand significant external force, facilitating manual movement of the limiting protrusion 5. Furthermore, a positioning structure can be provided between the lever 9 and the limiting protrusion 5 to prevent displacement during movement and ensure that the limiting protrusion 5 maintains correct contact with the guide block 4 during operation.

[0044] In actual operation, when this device is used, the mesh body 2 is embedded inside the frame 1, the connector 3 is threaded to the frame 1 through the embedded section 31, and the edge of the mesh body 2 is inserted into the locking groove 33. The limiting protrusion 5 enters the positioning hole 32, and the guide block 4 positions the mesh body 2 so that the mesh body 2 is stably installed on the frame 1. When disassembling, simply rotate the connector 3 to make the limiting protrusion 5 disengage from the positioning hole 32, and the mesh body 2 can be taken out from the frame 1 to complete the replacement process.
