Description

Technical Field

[0001] The utility model relates to the technical field of protective housing equipment, in particular to a ventilation and heat dissipation type protective housing. Background Art

[0002] A protective housing refers to a device used to protect the components inside the housing, which can mainly protect against external pressures such as collisions and dust. The protective housing is usually made of wear-resistant materials such as metal to ensure the normal and stable operation of the electronic components inside the protective housing. In different application scenarios and for different internal devices, the main functions of the protective housing will also vary. For example, a protective housing for protecting power equipment needs to have an insulating function to ensure the safety protection function of the protective housing.

[0003] The following problems often exist in the prior art during use:

[0004] 1. A protective housing with a ventilation and heat dissipation function usually has a plurality of heat dissipation ventilation openings on the housing to ensure the heat dissipation performance of the machine inside the protective housing. However, this type of protective housing is not convenient to use in scenarios with a large amount of dust, that is, dust is very easy to enter the protective housing through the ventilation openings, reducing the protection performance of the protective housing and affecting the normal operation of the machine inside the protective housing.

[0005] 2. Since the gas with heat, that is, hot air, has a lower air pressure and a smaller density, the hot air inside the protective housing will be located above the inside of the protective housing. Moreover, the blowing direction of the ventilation openings or the cooling fans is not easy to adjust, resulting in a relatively limited ventilation and heat dissipation effect inside the protective housing.

Detailed implementation manners

[0023] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0024] As Figures 1-3 shown, an embodiment of the present utility model provides a ventilation and heat dissipation type protective housing, which includes a protective housing 1 and two ventilation protection components: ventilation windows 2 are provided on both side walls of the protective housing 1; each ventilation protection component includes a plurality of rotating shafts 3 rotatably connected to the inner side of the ventilation window 2, a baffle 4 is fixedly connected to each rotating shaft 3, an anti-adhesive coating is provided on the outer surface of the baffle 4, and the sum of the sizes of the plurality of baffles 4 is equal to the size of the ventilation window 2. Small gears 5 are fixedly connected to both ends of each rotating shaft 3. A plurality of retaining holes are provided on the outer wall of the protective housing 1, and the small gears 5 are located in the retaining holes. A limit slide rail 6 is fixedly connected to the outer wall of the protective housing 1, and a first rack plate 7 is slidably connected in the limit slide rail 6. The rack on the first rack plate 7 meshes with the small gear 5.

[0025] Start the rotating motor 11, drive the adjusting screw 8 to rotate through the rotating motor 11, so that the slider 9 threadedly connected to the adjusting screw 8 moves up and down, and then the slider 9 drives the first rack plate 7 to move up and down through the connecting rod 10. The engagement between the first rack plate 7 and the small gear 5 is used to drive the rotating shaft 3 to rotate a certain angle, so as to drive the plurality of baffles 4 to rotate and adjust synchronously, so that the plurality of baffles 4 can cover the ventilation window 2 to improve the protection performance of the protective housing.

[0026] As Figure 1 shown, a driving component is provided on the top of the protective housing 1. The driving component includes an adjusting screw 8 rotatably connected to the top of the protective housing 1. A slider 9 is threadedly connected to the adjusting screw 8. The slider 9 is fixedly connected to the upper ends of the two first rack plates 7 through a connecting rod 10. A rotating motor 11 is installed on the top of the protective housing 1, and the output end of the rotating motor 11 is fixedly connected to the upper end of the adjusting screw 8 through a coupling.

[0027] Using the rotating motor 11 as a driving source to drive the connecting rod 10 to move up and down, so as to realize the synchronous linkage operation of the ventilation protection component and the wind direction adjustment component, which can effectively improve the linkage degree of the protective housing equipment and reduce the energy consumption of the protective housing equipment.

[0028] As shown Figure 1 in the figure, a wind direction adjusting component is arranged inside the protective housing 1. The wind direction adjusting component includes a rotating bracket 12 rotatably connected to the inner wall of the protective housing 1. An electric cooling fan 13 is arranged in the middle of the rotating bracket 12. A transmission gear 14 is fixedly connected to the rotating bracket 12.

[0029] When the adjustment baffle 4 rotates to an upward inclination angle, the slider 9 moves upward at this time, and then the slider 9 drives the connecting rod 10 to move upward, so that the second rack plate 15 at the bottom of the connecting rod 10 moves upward synchronously. Then, through the meshing of the second rack plate 15 and the transmission gear 14, the rotating bracket 12 is driven to rotate, so that the electric cooling fan 13 starts to rotate upward by a certain angle, thereby quickly blowing away the hot air above the inside of the protective housing 1 and improving the heat dissipation and ventilation effect inside the protective housing 1.

[0032] 2. When the adjustment baffle 4 rotates to an upward inclination angle, the slider 9 moves upward at this time, and then the slider 9 drives the connecting rod 10 to move upward, so that the second rack plate 15 at the bottom of the connecting rod 10 moves upward synchronously. Then, through the meshing of the second rack plate 15 and the transmission gear 14, the rotating bracket 12 is driven to rotate, so that the electric cooling fan 13 starts to rotate upward by a certain angle, thereby quickly blowing away the hot air above the inside of the protective housing 1 and improving the heat dissipation and ventilation effect inside the protective housing 1.
