Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan protective cover technology, specifically a fan cover with a long service life. Background Technology
[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. The term "fan" generally includes ventilators, blowers, and wind turbines. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling; in boilers and industrial furnaces for ventilation and induced draft; in air conditioning equipment and household appliances for cooling and ventilation; in grain drying and conveying; as a wind source for wind tunnels; and for inflating and propelling hovercraft. The fan cover protects the fan blades.
[0003] Existing fan covers tend to accumulate a lot of dust during prolonged use, requiring frequent disassembly and cleaning. However, because they are secured with multiple bolts, users have to unscrew each bolt individually, resulting in low disassembly efficiency and a lack of practicality. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a fan cover with a long service life and the advantage of easy disassembly and cleaning, thus solving the problem of inconvenient disassembly and cleaning of the fan cover.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a long-service-life fan cover, comprising a main body assembly; the main body assembly includes a fan body, the front surface of which is fixedly connected to a mounting shell; a horizontal plate, slidably connected to the inner side wall of the mounting shell; a dustproof net, disposed on the horizontal plate; the fan body is provided with a disassembly assembly, the disassembly assembly comprising: a mounting plate, fixedly connected to the outer side wall of the mounting shell; limiting grooves, symmetrically opened on the outer side wall of the horizontal plate; mounting grooves, symmetrically opened inside the mounting plate; limiting blocks, each of the mounting grooves is slidably connected to a limiting block; a pull rod, each of the limiting blocks is fixedly connected to a pull rod; and a spring, each of the limiting blocks is provided with a spring.
[0008] Preferably, springs are symmetrically arranged inside the mounting plate.
[0009] Preferably, each of the limiting blocks has a plate fixedly connected to its outer side wall.
[0010] Preferably, each of the limiting blocks has a slope on one side.
[0011] Preferably, the fan body is provided with a linkage assembly, which includes: a U-shaped plate, fixedly connected to the outer wall of the mounting plate; a push plate, inserted into the U-shaped plate; an L-shaped plate, with an L-shaped plate fixedly connected to the outer wall of each pull rod, and the two L-shaped plates slidably connected to the inner wall of the U-shaped plate; and a rotating rod, with a rotating rod hinged to the outer wall of each L-shaped plate, and the other end of the two rotating rods hinged to the outer wall of the push plate.
[0012] Preferably, the push plate is provided with a spring three, and the two ends of the spring three are respectively fixedly connected to the outer wall of the push plate and the inner wall of the U-shaped plate.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a fan cover with a long service life, which has the following beneficial effects:
[0015] This invention has the advantage of facilitating the disassembly and cleaning of the fan cover. When the dust filter needs to be cleaned, the operator pulls two levers simultaneously, causing the levers to pull the limiting block to slide in the mounting groove and move it out of the limiting groove on the horizontal plate. This causes the limiting block to compress the spring, thereby releasing the limiting block from fixing the horizontal plate. This allows the operator to pull the horizontal plate out of the mounting shell and clean the dust filter on the horizontal plate without having to tighten multiple bolts, which is time-consuming and laborious. This solves the problem of the fan cover being inconvenient to disassemble and clean. Attached Figure Description

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example 1
[0027] See Figure 1-4 A long-life fan cover includes a main body assembly 1; the main body assembly 1 includes a fan body 11, the front surface of which is fixedly connected to a mounting shell 12; a horizontal plate 13, slidably connected to the inner side wall of the mounting shell 12; a dustproof net 14, disposed on the horizontal plate 13; a disassembly assembly 2 is provided on the fan body 11, the disassembly assembly 2 includes: a mounting plate 21, fixedly connected to the outer side wall of the mounting shell 12; limiting grooves 22, symmetrically opened on the outer side wall of the horizontal plate 13; mounting grooves 23, symmetrically opened inside the mounting plate 21; limiting blocks 24, each of the mounting grooves 23 is slidably connected to a limiting block 24; a pull rod 25, each of the limiting blocks 24 is fixedly connected to the outer side wall; a first spring 26, each of the limiting blocks 24 is provided with a first spring 26; a second spring 5 is symmetrically arranged inside the mounting plate 21; a plate body 4 is fixedly connected to the outer side wall of each limiting block 24; and an inclined surface is provided on one side of each limiting block 24.
[0028] In use, the mounting shell 12 is fixedly installed on the fan body 11. When the dust screen 14 needs to be cleaned, the operator simultaneously pulls the two pull rods 25 on the mounting plate 21, causing the pull rods 25 to pull the limiting block 24 to slide in the mounting groove 23. This causes the limiting block 24 to move out of the limiting groove 22 on the horizontal plate 13, and the limiting block 24 to compress the spring 1 26. This releases the limiting block 24 from the horizontal plate 13, allowing the operator to pull the horizontal plate 13 out of the mounting shell 12 for cleaning the dust screen 14. This eliminates the need to tighten multiple bolts, which is time-consuming and laborious, thus improving the practicality of the device. The mounting plate 21 also has symmetrically arranged springs 25. When the horizontal plate 13 is inserted into the mounting plate 21, it compresses the springs 25. When the operator releases the limiting block 24 from the horizontal plate 13, the limiting block 25 is released from the mounting shell 21. When the limit is reached, spring 25 automatically pops out the horizontal plate 13, eliminating the need for manual pulling by the operator and improving the operator's work efficiency. Each limit block 24 has a plate 4 fixedly connected to its outer wall. The surface of the plate 4 is provided with a lubricating layer, which can reduce the friction between the limit block 24 and the inner wall of the limit groove 22, making it easier for the operator to pull the limit block 24. This avoids the problem of excessive friction between the limit block 24 and the limit groove 22 under the elastic force of spring 25, which makes it difficult to pull out, thus improving the stability of the device. Each limit block 24 has an inclined surface on one side. When the operator installs the horizontal plate 13, the edge of the horizontal plate 13 presses against the inclined surface of the limit block 24, causing the limit block 24 to move automatically without the operator having to pull the pull rod 25 first, thus improving the convenience of the device.
[0029] Example 2
[0030] See Figure 1-4 Based on the first embodiment, a linkage function has been added;
[0031] The fan body 11 is provided with a linkage component 3, which includes: a U-shaped plate 31, fixedly connected to the outer wall of the mounting plate 21; a push plate 32, inserted into the U-shaped plate 31; an L-shaped plate 33, with each pull rod 25 having an L-shaped plate 33 fixedly connected to its outer wall, and both L-shaped plates 33 being slidably connected to the inner wall of the U-shaped plate 31; a rotating rod 34, with each L-shaped plate 33 having a rotating rod 34 hinged to its outer wall, and the other ends of both rotating rods 34 being hinged to the outer wall of the push plate 32; and a spring 6 is provided on the push plate 32, with both ends of the spring 6 being fixedly connected to the outer wall of the push plate 32 and the inner wall of the U-shaped plate 31, respectively.
[0032] In use, the operator presses the push plate 32 on the U-shaped plate 31, causing the push plate 32 to simultaneously drive the two rotating rods 34 to rotate. The rotating rods 34 push the L-shaped plate 33, thereby causing the L-shaped plate 33 to move the pull rod 25 outward. This eliminates the need for the operator to pull the pull rods 25 on both sides separately, thus improving the convenience of the device. The push plate 32 is equipped with a spring 6. When the push plate 32 moves, it compresses the spring 6. When the push plate 32 needs to be reset, the spring 6 can compress the push plate 32 to move outward, thus ensuring the stability of the push plate 32's reset.
