JP3034891U - Ventilation lid for ventilation pipe - Google Patents

Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: It is possible to easily attach a lid lattice to a surface lattice or an insect net, so that the surface lattice can be replaced. SOLUTION: A flange 3 that engages with the ventilation pipe 10 is made outward and a receiving portion piece 4 is made inward on a base portion of a tubular portion 2 that is fitted and assembled in the ventilation pipe 10. The lid body 1 is formed by projecting. A ring-shaped lattice 8 in which a female screw 5 is provided on the inner side of the base of the cylindrical portion 2 of the lid main body 1, and an appropriate number of rods 7 are provided on a ring-shaped main body 6 to prevent rat intrusion. The main body 6 is screwed.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a ventilation lid for a ventilation pipe that is used in a building, for example, for blocking the open end of a ventilation pipe used for air conditioning equipment so as to prevent invasion of rats or insects.

[0002]

[Prior art]

 A lid main body is formed by outwardly projecting a flange that engages with the ventilation pipe at a base end portion of a tubular portion that is fitted into the ventilation pipe and assembled, and a ring-shaped main body is appropriately formed inside the base portion of the lid main body. There is a structure that engages and welds a surface lattice with a number of rods for preventing mouse intrusion.

[0003]

[Problems to be solved by the device]

 Although the above-mentioned conventional example can prevent the invasion of rats, it cannot prevent invasion of insects such as mosquitoes and flies, and since the welding means is used to assemble the plane lattice to the lid body, Attachment work is complicated.

[0004]

[Means for Solving the Problems]

 A lid main body is formed by projecting a flange that engages with the ventilation pipe in an outward direction and a receiving portion piece in an inward direction at a base end portion of a cylindrical portion that is fitted into the ventilation pipe and assembled. A female screw is provided on the inside of the base of the tubular portion of the lid body, and a ring-shaped main body of a surface lattice in which an appropriate number of rods for preventing intrusion of mice are erected on the ring-shaped main body is screwed into the female screw. With this as a basic means, an insect repellent net is interposed between the receiving part and the surface lattice, and an insect repellent effect is expected.

[0005]

【Example】

 The drawings show an embodiment of a ventilation cover for a ventilation pipe according to the present invention. FIG. 1 is a longitudinal sectional view and FIG. 2 is an exploded perspective view.

In the figure, 1 is a lid main body, and the lid main body 1 is such that a flange 3 for engaging with the ventilation pipe 10 is outwardly attached to a base end portion of a tubular portion 2 to be fitted and assembled in the ventilation pipe 10. Further, the receiving portion pieces 4 are provided so as to project inward, and the female screw 5 is provided inside the base portion of the tubular portion 2.

The female screw 5 of the lid main body 1 is screwed with the male screw 9 provided on the ring-shaped main body 6 of the surface lattice 8 to assemble the surface lattice 8 into the lid main body 1 and the surface lattice 8 and the receiving member. The insect cover 11 is interposed between the stopper piece 4 to form the ventilation lid A.

The plane lattice 8 of the ventilation lid A is constructed by arranging an appropriate number of rods 7 for preventing intrusion of a mouse on a ring-shaped main body 6 provided with the male screw 9 on the peripheral surface. Is.

The lid body 1, the surface lattice 8 and the insect screen 11 are made of metal.

The illustrated ventilation pipe 10 is for introducing the outdoor air into the room by letting the opening end look outside, and is made of vinyl chloride, and the ventilation cover A is fitted and pushed on the opening end. Of.

[0011]

[Effect of the invention]

 Since the present invention is configured as described above, the lid main body and the surface grid or insect screen can be easily assembled, and the fixing means that cannot be disassembled as in the conventional case is not adopted. You can still change.

[0012] From the beginning, it is possible to prevent the invasion of rats and to expect an insect repellent effect.
