Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to an indoor ventilation mechanism used for building decoration. Background Art

[0002] During the construction and decoration process, there are many dust particles indoors. Ventilation can effectively remove pollutants such as dust and harmful gases generated at the construction site, maintain the air quality of the construction environment, and reduce the risk of construction workers inhaling harmful substances. Therefore, ventilation equipment needs to be installed during the construction and decoration process to ensure stable ventilation.

[0003] Existing ventilation devices circulate air by setting up fans and other blowing components. However, when there is a lot of dust indoors, the disturbance of the airflow can easily cause the dust to float everywhere, affecting the air quality and the ventilation effect. Similarly, exhaust fans are also set up to discharge the dust to the outside. However, the setting position of the exhaust fan is generally fixed, which makes it impossible to ventilate and remove dust in a large area indoors. Utility Model Content

[0004] In view of the above problems existing in the existing indoor ventilation mechanisms used for building decoration, the present utility model is proposed.

[0005] Therefore, the purpose of the present invention is to provide an indoor ventilation mechanism for building decoration, which solves the problem that there is a lot of indoor dust after building decoration and the dust cannot be discharged while performing effective ventilation.

An adjusting screw is passed through the internal thread of the internal threaded tube, and the top of the adjusting screw is fixedly connected to the positioning plate.

[0010] Preferably, two symmetrically arranged guide telescopic rods are fixedly provided between the positioning plate and the side wall of the support ring.

[0012] Furthermore, the positioning plate is a U-shaped positioning plate, and an anti-slip silicone pad is fixedly provided on the inner wall of the U-shaped positioning plate.

[0013] Preferably, a rotating block is fixedly provided on the lower end of the outer wall of the internally threaded tube, and a plurality of anti-slip protrusions arranged in a symmetrical manner around the outer wall of the rotating block are fixedly provided.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the utility model discloses an indoor ventilation mechanism for building decoration.

[0025] The utility model provides Figure 1-3 An indoor ventilation mechanism for building decoration shown in the figure includes a support ring 1, a vertical rod 2 is rotatably provided on the top of the inner wall of the support ring 1, an exhaust fan 3 is fixedly provided on the bottom of the vertical rod 2, a mounting plate 4 is fixedly provided on the side wall of the support ring 1, a reciprocating electric cylinder 5 is fixedly provided on the side wall of the mounting plate 4, a rack 6 is fixedly provided on the end of the output shaft of the reciprocating electric cylinder 5, a gear 7 is fixed on the rod wall fixing sleeve of the vertical rod 2, the rack 6 is matched with the gear 7, the outer cover of the exhaust fan 3 is provided with a dust filter 12, and a plurality of mounting bolts 13 symmetrically arranged in a circle are threadedly passed through the dust filter 12 and the exhaust fan 3.

[0026] When it is necessary to ventilate the room during the building decoration process, the support ring 1 is set in the window frame and the exhaust fan 3 is started, so that the exhaust fan 3 can discharge the indoor dirty air to the outside, and at the same time cooperate with the window sash inside the house to transport the fresh air from the outside into the room. While exhausting, the dust in the air can be concentrated on the surface of the dust filter 12, which can not only centrally treat the dust, but also prevent the dust from diffusing to the outside and affecting the air quality. At the same time as the exhaust fan 3 is started, the reciprocating electric cylinder 5 starts to work, so that the rack 6 moves back and forth and can engage the gear 7 to drive the vertical rod 2 to rotate back and forth, so that the exhaust fan 3 performs swing exhaust work, which can perform exhaust and ventilation work in a larger range in the room and improve the ventilation effect.

[0027] In order to stably install the exhaust fan 3 inside the window frame, Figure 1-3 As shown, positioning plates 8 are provided on both sides of the support ring 1. The positioning plates 8 are U-shaped positioning plates. The inner walls of the U-shaped positioning plates are fixed with anti-slip silicone pads 14. Two symmetrically arranged guide telescopic rods 11 are fixed between the positioning plates 8 and the side walls of the support ring 1. A movable adjustment mechanism for adjusting the position of the positioning plates 8 is provided between the positioning plates 8 and the side walls of the support ring 1. The movable adjustment mechanism includes an internal threaded tube 9. The internal thread of the internal threaded tube 9 is rotatably connected to the top of the support ring 1. An adjusting screw 10 is passed through the internal thread of the internal threaded tube 9. The top of the adjusting screw 10 is fixedly connected to the positioning plate 8. A rotating block 15 is fixed at the lower end of the outer wall of the internal threaded tube 9. The outer wall of the rotating block 15 is fixed with a plurality of anti-slip protrusions 16 that are symmetrically arranged around.

[0028] Before performing ventilation work, the support ring 1 is set in the window frame, and the two rotating blocks 15 are rotated to rotate the internal threaded tube 9. Due to the threaded fit between the internal threaded tube 9 and the adjusting screw 10, when the internal threaded tube 9 rotates, the positioning plate 8 is supported by the two telescopic rods 11 and pushed by the adjusting screw 10, so that the positioning plate 8 is stably sleeved on the outside of the side of the window frame, thereby completing the position determination of the exhaust fan 3 and the overall device, so that the exhaust ventilation work can be carried out stably.

[0029] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
