Description

Technical Field

[0001] This utility model relates to the field of fan guard technology, specifically an antistatic fan guard. Background Technology

[0002] Fans are widely used in heat dissipation, ventilation, and dust removal. Their air inlets and outlets are usually equipped with metal protective mesh covers. When the fan is running, the high-speed airflow continuously rubs against the metal mesh cover, generating a large amount of static charge.

[0003] Traditional metal mesh covers are typically treated with powder coating or baking paint. These coatings are mostly insulators, causing static charges to accumulate due to the inability to dissipate in time. Static charge accumulation leads to a series of problems: the electrostatic field strongly attracts charged dust and fibers from the air, causing blockage of the mesh cover's ventilation holes, reduced fan efficiency, and poor heat dissipation. In environments with flammable and explosive gases, such as chemical or oil / gas plants, electrostatic sparks can even pose an extreme risk of explosion. Furthermore, operators touching the mesh cover may suffer brief electrostatic shocks, which, while not fatal, are uncomfortable. To address these issues, we propose an anti-static fan mesh cover. Utility Model Content

[0004] The purpose of this invention is to provide an antistatic fan cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antistatic fan guard, comprising: The device comprises an annular mounting base and a mesh cover body. The mesh cover body is mounted on the annular mounting base and includes an annular outer frame. Four annular mesh cover skeletons are fixedly welded to the inner wall of the annular outer frame. Multiple mesh rings are fixedly welded to the four mesh cover skeletons. The mesh cover skeletons and the mesh rings are made of antistatic metal composite material. Two symmetrically arranged snap-fit ​​mechanisms are provided on the annular mesh frame. Two symmetrically arranged L-shaped fixing seats are fixedly mounted on the outer wall of the annular mounting base, and snap-fit ​​seats are fixedly welded to the L-shaped fixing seats.

[0006] Preferably, a conductive bolt is threaded to the outer end of one of the mesh frame frames, and a wire is fixedly connected to the conductive bolt.

[0007] Preferably, the snap-fit ​​mechanism includes a rectangular housing, which is fixedly welded to an annular outer frame. A groove is provided on the outer wall of the rectangular housing, and a slider is slidably connected in the groove. A snap-fit ​​post is fixedly welded to the outer end of the slider. A tension spring is provided in the inner cavity of the rectangular housing, and the two ends of the tension spring are fixedly connected to the inner cavity wall of the rectangular housing and the slider, respectively.

[0008] Preferably, the locking base has an L-shaped locking groove, the width of which is adapted to the diameter of the locking post.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the mesh cover body is composed of a mesh cover frame made of antistatic metal composite material and multiple mesh rings. A conductive bolt is threaded onto one of the mesh cover frames, and a wire is installed on the conductive bolt. When the fan mesh cover is in use, the wire can be fixedly connected to the ground or the wiring of the equipment, so that the static charge on the mesh cover body can be conducted to the conductive bolt and discharged through the wire. This gives the mesh cover body strong antistatic performance and avoids the problems of dust collection and blockage, fire hazards and electric shock caused by static electricity. 2. The annular mounting base of this utility model can be welded to the air outlet or air inlet of the fan during use.

[0012] 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.

[0013] Please see Figure 1-4This utility model provides a technical solution: an antistatic fan guard, comprising: The ring mounting base 1 and the mesh cover body 2 are provided. The mesh cover body 2 is mounted on the ring mounting base 1. The mesh cover body 2 includes a ring outer frame 3. Four ring-shaped mesh cover skeletons 4 are fixedly welded to the inner wall of the ring outer frame 3. Multiple mesh rings 5 ​​are fixedly welded to the four mesh cover skeletons 4. The mesh cover skeletons 4 and the mesh rings 5 ​​are both made of antistatic metal composite material. The antistatic metal composite material is made by adding conductive material to a metal matrix. Two symmetrically arranged snap-fit ​​mechanisms 6 are provided on the ring mesh frame 3. Two symmetrically arranged L-shaped fixing seats 7 are fixedly mounted on the outer wall of the ring mounting base 1. Snap-fit ​​seats 8 are fixedly welded to the L-shaped fixing seats 7.

[0014] A conductive bolt 9 is threaded to the outer end of one of the mesh frame 4, and a wire 10 is fixedly connected to the conductive bolt 9. The conductive bolt 9 and the wire 10 can facilitate the discharge channel for static charge.

[0015] The snap-fit ​​mechanism 6 includes a rectangular housing 11, which is fixedly welded to the annular outer frame 3. A groove 12 is provided on the outer wall of the rectangular housing 11, and a slider 13 is slidably connected in the groove 12. A snap-fit ​​post 14 is fixedly welded to the outer end of the slider 13. A tension spring 15 is provided in the inner cavity of the rectangular housing 11, and the two ends of the tension spring 15 are fixedly connected to the inner cavity wall of the rectangular housing 11 and the slider 13, respectively.

[0016] The locking seat 8 is provided with an L-shaped locking groove 16. The width of the L-shaped locking groove 16 is adapted to the diameter of the locking post 14. After the locking post 14 slides into the L-shaped locking groove 16, it can be locked into the inner end position of the L-shaped locking groove 16 under the pulling force of the tension spring 15 acting on the slider 13, thereby fixing the mesh cover body 2 on the annular mounting seat 1.

[0017] Working principle: In use, the mesh cover body 2 consists of a mesh cover frame 4 made of antistatic metal composite material and multiple mesh rings 5. A conductive bolt 9 is threaded onto one of the mesh cover frames 4, and a wire 10 is installed on the conductive bolt 9. The wire 10 can be fixedly connected to the ground or the equipment wiring during use, allowing the static charge on the mesh cover body 2 to be conducted to the conductive bolt 9 and discharged through the wire 10. This gives the mesh cover body 2 strong antistatic properties, preventing dust accumulation and blockage, fire hazards, and electric shock caused by static electricity. The mounting base 1 can be welded to the air outlet or air inlet of the fan during use. The mesh cover body 2 is installed on the ring mounting base 1 by the snap-fit ​​mechanism 6 and the snap-fit ​​seat 8. This facilitates the disassembly and assembly of the mesh cover body 2 and improves the convenience of maintenance or replacement. The disassembly steps of the mesh cover body 2 are as follows: pull the two snap-fit ​​posts 14 in opposite directions at the same time, so that the two snap-fit ​​posts 14 move to the corner of the L-shaped snap-fit ​​groove 16. Then rotate the mesh cover body 2 clockwise so that the two snap-fit ​​posts 14 disengage from the two snap-fit ​​seats 8 respectively. Finally, pull the mesh cover body 2 outward to separate it from the ring mounting base 1.
