Description

Technical Field

[0001] The utility model relates to the technical field of equipment fan structure design, in particular to a heat dissipation fan protective cover structure. Background Art

[0002] Due to design reasons, the actual usage conditions of the daily necessities paper cutting equipment were not taken into consideration. The air inlet cover of the cooling fan has no protective part. During use, iron wire often gets stuck in the fan, causing damage to the fan and deformation of the impeller. The equipment adopts a traditional grid-type cover structure in the design of the air inlet cover of the cooling fan. Although the air intake volume is large, during actual use of the equipment, iron wire is frequently entangled in the fan blade part, causing deformation of the fan blade and even damage to the cooling structure. If a closed structure is used to shield the fan blade part, although the problem of iron wire being entangled in the fan blade can be avoided, it affects the air intake of the cooling fan, thereby affecting the heat dissipation of the equipment, and urgently needs to be improved. Therefore, we propose a cooling fan protective cover structure. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1, as Figure 1-3 As shown, the utility model provides a technical solution: a heat dissipation fan protective cover structure, including a frame-type cover 1, a square groove 1 4 is opened on one side of the frame-type cover 1, a plurality of inverted V-shaped baffles 5 are fixedly arranged on the inner wall of the square groove 1 4 at vertical equidistant intervals, two vertical side walls of the frame-type cover 1 that are opposite to each other are both vertically equidistantly opened with a plurality of square grooves 2 6, an arc-shaped baffle 3 is fixedly arranged on the outside of the square groove 2 6, four fixing plates 2 are fixedly arranged on the end face of one side of the frame-type cover 1 that is away from the square groove 1 4, and two parallel square holes are opened on the surface of each fixing plate 2.

[0020] In a specific embodiment of the present invention, four fixing plates 2 are respectively arranged horizontally at four right angles of the open end surface of the frame cover 1, and the square holes on the surface of the fixing plates 2 can overlap with the outer shell of the fan part of the equipment, and then the bolts are embedded in the square holes on the surface of the fixing plates 2 by bolt fastening, so that the frame cover 1 is installed on the outer shell of the fan part of the equipment. The two opposite vertical side plates of the frame cover 1 are provided with a plurality of square grooves 6, and the spacing between two adjacent square grooves 6 is 30mm. The square grooves 6 are provided on both sides of the frame cover 1 for the fan to enter. The arc surface of the arc baffle 3 just blocks the square groove 2 6, and foreign objects like iron wire cannot easily pass through the arc baffle 3 and enter the inside of the square groove 2 6. The square groove 1 4 is vertically equidistantly welded with multiple inverted V-shaped baffles 5. Due to the special structure of the inverted V-shaped baffle 5, foreign objects like iron wire cannot easily pass through the gaps between the inverted V-shaped baffles 5. The convex body 501 is provided to block the end of foreign objects like iron wire, so as to prevent foreign objects like iron wire from sliding along the surface of the inverted V-shaped baffle 5 and passing through the gaps between the inverted V-shaped baffles 5.

[0021] In the preferred technical solution, the angle of the inverted V-shaped baffle 5 is set to 50°, and the spacing between the top corners of two adjacent inverted V-shaped baffles 5 is half of the overall height of the inverted V-shaped baffle 5, so that foreign objects such as iron wire cannot easily pass through the gap between two adjacent inverted V-shaped baffles 5.

[0022] In the preferred technical solution, a plurality of protrusions 501 are fixedly provided on the inclined surface of one side of the inverted V-shaped baffle bar 5, and the distance between two adjacent protrusions 501 is set to 20 mm. The protrusions 501 can block the ends of foreign objects such as iron wires, thereby increasing the difficulty for the ends of foreign objects such as iron wires to enter the gap between two adjacent inverted V-shaped baffle bars 5.

[0023] In the preferred technical solution, the bottom plane of the arc-shaped baffle 3 is 5 mm lower than the bottom plane of the square groove 2 6 at the same position, the length of the arc-shaped baffle 3 is 10 mm larger than the long side width of the square groove 2 6, and the arc surface of the arc-shaped baffle 3 just blocks the square groove 2 6, so that foreign objects such as iron wire cannot easily pass through the arc-shaped baffle 3 and enter the inside of the square groove 2 6.

[0024] In the preferred technical solution, the width of the long side of the square hole is 15 mm, which is conducive to reserving space for installation and adjustment when the bolts are mated.

[0025] To sum up, compared with the traditional grille-type fan air inlet cover, the above embodiment, by providing an inverted V-shaped baffle 5 structure and an arc-shaped baffle 3 structure, ensures a large air intake volume of the fan while preventing foreign objects such as iron wire from easily reaching the fan blade part, thereby increasing the service life of the fan and ensuring safe and continuous production work.
