However, in the louver device in the prior art, since the louver cover is directly fixed to the louver mounting body, the louver cover does not attach straight unless the louver mounting body is attached straight. By attaching a louver to a window provided for ventilation, dust and rainwater can be prevented from entering while ventilating. However, there was a drawback that internal devices were consumed. And in this louver device, when correcting the direction of the louver, it was necessary to start by removing all the parts and reattaching the louver mounting body, which took a lot of trouble.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a louver mounting structure that can easily adjust the mounting direction of a louver with a simple structure, and the structure includes a base body located inside a ventilation window, and a base A fixed body that is directly fixed to the body and a cover body that is fitted to the fixed body by elastic deformation. A groove is formed on the peripheral edge of the fixed body, and a groove is formed on the inner peripheral edge of the cover body. Protruding portions to be guided are provided.

  Further, a plurality of protrusions are provided on the inner periphery of the cover body, and a stopper for restricting the movement of each protrusion is provided in the groove.

  The louver mounting structure according to the present invention includes a base body located inside the ventilation window, a fixed body that is directly fixed to the base body, and a cover body that is fitted to the fixed body by elastic deformation. A groove is formed on the peripheral edge of the body, and a protrusion guided by the groove is provided on the inner peripheral edge of the cover body. Therefore, the cover body is attached to the fixed body instead of the base body, Can be adjusted from outside the cabinet. Work efficiency can be improved without using a special tool.

  In addition, there are a plurality of protrusions provided on the inner periphery of the cover body, and the groove is provided with a stopper that restricts the movement of each protrusion part. It is a structure that can be adjusted.

It is explanatory drawing which shows the louver attachment structure which concerns on this invention. It is a disassembled perspective view which shows the louver attachment structure which concerns on this invention. It is explanatory drawing which shows the state which attaches the louver which concerns on this invention to a cabinet. It is explanatory drawing which looked at the louver attachment structure which concerns on this invention from the cabinet outer side. It is a partially expanded view of the louver mounting structure according to the present invention. It is explanatory drawing which shows the cover body of the louver which concerns on this invention.

  An embodiment of a louver mounting structure according to the present invention will be described with reference to the accompanying drawings of FIGS.

  A ventilation window 2 is opened in the cabinet 1 in order to suppress an increase in the internal temperature of the cabinet 1 that houses electrical equipment and communication equipment. This is a louver mounting structure provided to prevent dust and rainwater from entering the ventilation window 2.

  The cover body 3 has a structure in which a plurality of vent holes 4 are formed on the front surface, gaps are formed, and louvers 5 are provided in the respective vent holes 4 in order to prevent entry of dust and rainwater. A space 8 for storing the filter 6 and the insect net 7 is formed on the back surface of the cover body 3. A protrusion 9 is formed on the inner periphery of the back surface. A notch 11 is formed in the side surface portion 10 from the back surface to the front surface. A screw portion 12 is provided at a substantially central portion of the cover body 3.

  The fixed body 13 has a substantially cylindrical shape, and an internal thread portion 15 is formed inside the cylindrical portion 14. A groove 16 having a width that allows the protrusion 9 provided on the cover body 3 to move is provided on the peripheral edge of the front surface side of the fixed body 13. A screw receiving portion 17 is provided at a substantially central portion of the fixed body 3.

  The base body 18 includes a cylindrical male screw portion 19 having a thread groove formed on the entire side surface, and a frame piece 20 formed on the back side of the male screw portion 19. A vent hole 21 and a gallery 22 are further formed inside the base body 18.

  A spacer 20 may be attached to the base body 18 so as to cover the male screw portion 19 so that no gap is generated between the base body 18 and the fixed body 13. The spacer 20 is formed with a locking body 23, and the base body 18 is formed with a locking receiving portion 24 on which the locking body 23 can be locked. The locking body 23 of the spacer 20 is an elastic body and is fitted to the locking receiving portion 24 of the base body 18. Further, when the spacer 20 is attached to the base body 18 via the packing 25, the airtightness is further enhanced.

  The base body 18 is applied to the ventilation window 2 provided in the cabinet 1 from the inside. The fixed body 13 is applied from the outside of the cabinet 1, the base body 18 and the fixed body 13, and the respective female screw portion 15 and the male screw portion 19 are screwed to face each other, and the base body 18 and the fixed body 13 are inserted into the ventilation window 2. To fix.

  The cover body 3 is attached to the front surface side of the fixed body 3, and foreign matter such as dust and insects from the outside of the cabinet 1 such as the filter 6 and the insect net 7 is inserted between the cover body 3 and the fixed body 13. A thing to prevent further is provided. Using the elasticity of the cover body 3, the protrusion 9 of the cover body 3 is fitted into the groove 16 of the fixed body 13. Then, screws 26 are respectively inserted from the front into the screw portion 12 of the cover body 3 and the screw receiving portion 17 of the fixed body 3 and tightened to fix the cover body 3 to the fixed body 13.

  After fixing, if the gallery 5 of the cover body 3 is not horizontal, the screw 26 is loosened and the projection 9 of the cover body 3 is guided in the groove 16 of the fixed body 13 to align the cover body 3. After that, the screw 26 is retightened and fixed.

  Further, the notch 11 provided on the side surface of the cover body 3 is for inserting a tool such as a screwdriver when it is desired to remove the cover body 3 once attached to the fixed body 13.

  The louver mounting structure according to claim 2 provides a structure for restricting the rotation angle of the cover body 3. A plurality of stoppers 25 are formed in the groove 16 provided in the fixed body 13 by dividing the circumference of the fixed body 13. In order to adjust the cover body 3 toward the louver 5, it is not necessary for the cover body 3 to rotate once, so that the protrusion 9 is guided by the groove 16 between the stoppers 25. By restricting the range in which the cover body 3 can be rotated, the attachment direction of the cover body 3 can be adjusted more easily.

  Further, since the groove 16 is provided in the circumferential portion of the fixed body 13, the position of the stopper 27 is not visible when viewed from the front, so that a projection 28 as a mark can be provided on the front side. Using the protrusion 28 as a mark, the protrusion 9 of the cover body 3 is fitted into the groove 16 while avoiding the stopper 27, and the cover body 3 is attached to the fixed body 13.

  The louver configured as described above can prevent dust and rainwater from entering while ensuring air permeability, and can be easily installed on a ventilation window.
