Description
Technical Field
The utility model relates to a roof fan technical field especially relates to a rings waterproof construction of roof fan.
Background
Roof fan installs and airs exhaust on roofs such as workshop, factory building and takes a breath the use, and it is installed in outdoor abominable environment, and it is higher to rings seal structure requirement on the roof fan hood, and ordinary bolt structure can not satisfy this kind of seal structure requirement among the prior art, causes a small amount of water droplets to instil into roof fan inside and enter the workshop, can instil into roof fan's motor inside sometimes even, causes the motor to damage.
Disclosure of Invention
In view of the above shortcoming of the prior art, an object of the utility model is to provide a rings waterproof construction of roof fan can realize better water-proof effects through its physics waterproof construction.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a rings waterproof construction of roof fan, includes hood and rings body, its characterized in that:
the top surface of the blast cap is provided with a boss which is integrated with the blast cap and is higher than the top surface of the blast cap, and the middle part of the top surface of the boss is provided with a mounting hole;
the flying ring body comprises a bolt, a ring body and a nut, the head of the bolt is positioned at the upper part, a cavity for accommodating the upper part of the boss or all the bosses is arranged on the bottom surface of the head, the inner wall of the cavity is attached to the outer wall of the boss, and a screw rod of the bolt is positioned at the lower part and penetrates through the mounting hole; the nut is positioned on the lower side of the blast cap and is in threaded connection with the screw, and the nut abuts against the inner wall of the blast cap and is used for tensioning the head downwards; the ring body is longitudinally distributed and welded and fixed on the upper side of the head of the bolt.
The top surface of the cavity is also provided with a sealing groove which is distributed annularly, and a sealing ring is arranged in the sealing groove.
To sum up, the utility model discloses following beneficial effect has: structural design is reasonable, highly is higher than the hood top surface through the mounted position of boss with rings body, makes it avoid the rainwater to get into inside the hood through physical structure, and airtight contact structure between cooperation bolt and the boss makes it reach better water-proof effects simultaneously.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of a roof fan.
Fig. 2 is a schematic structural view of the hood.
Fig. 3 is a partial sectional view of "a" in fig. 2.
In the figure, 1 a roof fan body, 2 a blast cap, 3 a lifting ring body, 4 ring bodies, 5 heads, 6 nuts, 7 screws, 8 bosses, 9 chambers, 10 sealing grooves and 11 sealing rings.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
According to the illustrations of fig. 1 to 3: the utility model provides a rings waterproof construction of roof fan, including hood 2 and rings body 3, hood 2 is located roof fan body 1's top for waterproof use, and rings body 3 is then installed on hood 2's top surface, is used for roof fan body 1's hoist and mount to carry the use.
The top surface of the blast cap 2 is provided with a boss 8 which is integrated with the blast cap and is higher than the top surface of the blast cap, the boss 8 is in a round platform structure, the whole boss 8 is formed by a die in a stamping way, the middle part of the top surface of the boss 8 is provided with a mounting hole, the position of the mounting hole is higher than the top surface of the blast cap 2, the edge of the mounting hole is smaller than the top surface of the boss 8, and the outer side of the top surface of the boss 8 is provided with a certain sealing contact surface;
the lifting ring body 3 comprises a bolt, a ring body 4 and a nut 6;
the head 5 of the bolt is positioned at the upper part, a cavity 9 for accommodating all the bosses 8 is arranged on the bottom surface of the head 5, the inner wall of the cavity 9 is attached to the outer wall of each boss 8, and meanwhile, the bottom surface of the head 5 abuts against the top surface of the blast cap 2, so that the edge of the bottom surface of the head 5 is lower than the top surface of each boss 8, and rainwater is prevented from entering the mounting hole; a screw rod 7 of the bolt is positioned at the lower part and penetrates through the mounting hole for connecting and fixing the blast cap 2;
the nut 6 is positioned on the lower side of the blast cap 2 and is in threaded connection with the screw 7, and the nut 6 abuts against the inner wall of the blast cap 2 and is used for tensioning the head 5 downwards, so that the head 5 of the bolt is sealed, connected and fixed with the boss 8;
the ring body 4 is longitudinally distributed and welded and fixed on the upper side of the head part 5 of the bolt.
Further, in order to further ensure the sealing effect of the position of the mounting hole, a sealing groove 10 distributed annularly is further formed in the top surface of the cavity 9, a sealing ring 11 is arranged in the sealing groove 10, the sealing ring 11 is an O-shaped sealing ring, after the bolt is assembled, the inner side, the outer side and the upper side of the sealing ring 11 are respectively abutted against the inner wall of the sealing groove 10, the lower side of the sealing ring 11 is abutted against the sealing contact surface of the boss 8, and therefore the better sealing effect is integrally achieved, and the double sealing effect is achieved at the edge of the mounting hole.
The rings waterproof construction itself of roof fan has utilized the difference in height that exists between the top surface of mounting hole and hood 2 to prevent that the rainwater from getting into inside roof fan body 1, and the airtight connection effect of cooperation boss 8 and head 5 seals simultaneously, makes it be limited to be superior to the airtight structure among the prior art, finally still cooperates sealing washer 11 to make its airtight effect further promote.
The above is only the preferred embodiment of the present invention, as long as the preferred embodiment is realized by the same means, the objective technical solution of the present invention all belongs to the protection scope of the present invention.
