[0005] Compared to the prior art, the casing of the present invention uses the second venting body to rotate relative to the first venting body to displace the through holes, thereby changing the opening ratio of the ventilating device. Embodiments [0006] Referring to FIG. 1, a chassis of the present invention includes a housing 10 and a ventilation device 20. The housing 10 includes a side panel 12, and an opening (not shown) for ventilation is formed in the side panel 12. [Picture] Referring to FIG. 2 and FIG. 3, the ventilation device 20 can cover the opening of the side plate 12. The ventilating device 20 includes a first venting body 21 and a second venting body 22 pivotally coupled to the first venting body 21. The first venting body 21 is a disk having a plurality of through holes 1002035787-0, form number A0101 100121145, page 3 / page 12, 201251594, which includes a central hole 211 opened at the center and a plurality of central holes 211 Card hole 213. The first venting body 21 is provided with a plurality of fixing portions 212 adjacent to the periphery for fixing the first venting body 21 to the side plate 12 of the casing 1 and covering the opening of the side plate 12. The fixing portion 212 may be a magnet for adsorbing the first ventilation body 21 to the side plate 12, and the fixing portion 212 may be an adhesive for adhering the first ventilation body 21 to the side plate 12. In other embodiments, the fixing hole 212 may be opened at the fixing portion 212 to rivet the first ventilation member 21 to the side plate 12. The circumference of the first ventilation body 21 is provided with a plurality of indications 214, which respectively indicate the opening ratio of the ventilation device. [0009] The second ventilation body 22 is a disk with a plurality of through holes, which includes opening A central hole 221 at the center. The second venting body 22 has a diameter slightly smaller than that of the first venting body 21. A protrusion 222 is respectively protruded from the two ends of a diameter of the second ventilation body 22 adjacent to the circumference of the second ventilation body 22. The circumference of the second venting body 22 is provided with a marking line 224. [0010] Referring to FIG. 4 together, a rotating shaft 23 is configured to pivot the second ventilation body 22 through the central hole 211 of the first ventilation body 21 and the central hole 221 of the second ventilation body 22 to the first ventilation body. twenty one. The shaft 23 includes a shaft 231 and a head portion 232 and a threaded portion 234 which are respectively located at both ends of the shaft 231. The head portion 232 protrudes in the axial direction from a plurality of posts 233 which are parallel to the shaft 231. The post 233 can penetrate into the hole 213 around the center hole 211 of the first ventilating body 21 to prevent the rotation shaft 2 3 from rotating relative to the first venting body 21. After the shaft 231 passes through the central hole 221 of the second venting body 22, a spacer 24 and an elastic member 25 are sequentially sleeved on the shaft 231, and a nut 26 is locked to the threaded portion 234 of the rotating shaft 23 to be second. The ventilation body 22 is connected to the first ventilation body 21. 100121145 Form No. A0101 Page 4 / Total 12 Page 1002035787-0 201251594 [0011] In use, the boss 222 of the second ventilation body 22 is rotated to rotate the second passage $ _ 'to make the through hole of the p ventilation body 22 ― ventilate The body is called the through hole and is 22 bits to change the opening rate of the ventilation hole of the ventilation device 20. The opening ratio of the table B_ of the indication 214 is indicated by the indication of the indication line 224, which is indicated by the reference line 224, which indicates that the current The opening ratio of the state.
