Abstract

The utility model relates to a natural fresh air rotation switch device, which comprises a through wall pipe, a rotational wind volume adjust switch is arranged outside the inner end of the through wall pipe, the inner end is semi close, the left half is for ventilation, the end half of the wind volume adjust switch is left for the wind volume adjust port, the sealed section of the inner end of the through wall pipe and the wind volume adjust port are mutually covered. The utility model has the advantages of the simple structure, easy location, randomly adjusting the ventilation section area, easy installation and operation.

Description

Natural fresh wind rotary switching device

Technical field

The utility model relates to a kind of natural fresh wind rotary switching device, is mainly used in to be installed in register one's residence wall pipe the inner in the device of natural fresh air, to regulate ventilation.

Background technology

Existing a kind of natural fresh air device of registering one's residence mainly is connected with outdoor pipe by wall pipe, and a ventilation is regulated by sliding door or swing door in the inner of wall pipe.The shortcoming of sliding door is that structure is complicated, and the shortcoming of swing door is to be not easy the location.

Summary of the invention

The purpose of this utility model just provides a kind of natural fresh wind rotary switching device, to solve the problem that structure that prior art exists is complicated and be not easy to locate.

The technical solution of the utility model is: comprises wall pipe, outside the inner port of described wall pipe, is provided with a rotary airflow regulating switch, and half sealing of the inner port of this wall pipe, other half one leaves ventilating opening; Leave air quantity in half one of the end face of this airflow regulating switch and regulate mouthful, the enclosure portion of described wall pipe the inner is regulated mouth covering mutually with this air quantity.

Described airflow regulating switch is the circular lid shape, the outside or inboard that its round edge internal diameter and the external diameter or the internal diameter of described wall pipe cooperate and be enclosed within the inner port of covering wall pipe.

Between the inner port of described airflow regulating switch and wall pipe, be provided with the rotation clamping mechanism.

Described rotation clamping mechanism is made up of with the male structure that is located at described airflow regulating switch inner peripheral surface the scrobicular ring of the inner port outer peripheral face that is located at described wall pipe, and this scrobicular ring and male structure are coincide mutually and be connected together.

Side face at described airflow regulating switch is provided with the gap that several are uniformly distributed along the circumference.

The utility model has the advantages that simple in structure, easy location, the size of regulated at will draught area, easy to install and use.

The specific embodiment

Referring to Fig. 1～Fig. 8, the utility model comprises wall pipe 1, is provided with a rotary airflow regulating switch 2 outside the inner port of described wall pipe 1, and half sealing of the inner port of this wall pipe 1 leaves ventilating opening 3 in other half one; Leave air quantity in half one of the end face of this airflow regulating switch 2 and regulate mouthfuls 4.The enclosure portion of described wall pipe 1 the inner is regulated mouthful 4 coverings mutually with this air quantity, does not occur the slit when making both corresponding.

In the embodiment shown in fig. 1, described airflow regulating switch 2 is the circular lid shape, and its round edge internal diameter and the external diameter (or internal diameter) of described wall pipe 1 cooperate and be enclosed within the outside (or inboard) of the inner port of covering wall pipe 1.

In the embodiment shown in Fig. 2～7, between the inner port of described airflow regulating switch 2 and wall pipe, be provided with the rotation clamping mechanism, the rotation clamping mechanism of this embodiment is made up of with the salient point 6 that is located at described airflow regulating switch 2 inner peripheral surfaces the scrobicular ring 5 of the inner port outer peripheral face that is located at described wall pipe 1, and this scrobicular ring 5 coincide mutually with salient point 6 and is connected together.Can be provided with several gap that are uniformly distributed along the circumference (or slit) 7 at the side face of described airflow regulating switch 2,, make things convenient for salient point 6 to insert in the scrobicular ring 5 so that airflow regulating switch 2 edges have bigger elastic deformation.

Fig. 8 is the schematic diagram after the utility model turns an angle airflow regulating switch shown in Figure 32 in use, and the ventilating opening 3 of the inner port of wall pipe 1 partially overlaps with the air quantity adjusting mouth 4 of airflow regulating switch 2 at this moment, becomes draught area.By being rotated different angles, airflow regulating switch 2 can reach the purpose of regulating ventilation.
