Technical Field

[0001] The utility model relates to the technical field of windproof equipment, in particular to a windproof cover. Background Art

[0002] Existing vents are generally equipped with protective covers, the main purpose of which is to prevent rainwater from directly entering the room through the vents. For example, patent CN109812959A - a vent protective cover, but this type of protective cover has poor rain protection effect. To address this problem, patent CN105091271A proposes a rainproof exterior wall exhaust vent. This technology uses a lower air outlet to effectively prevent rainwater from blowing in. However, this technical solution is relatively complex in structure, not conducive to installation, and does not provide insect protection. Utility Model Content

[0008] In some possible implementations, the aluminum pressure plate is connected to the cover body via aluminum welding pins.

[0009] In some possible implementations, a buckle groove is provided on the mounting fastener, and a buckle tongue is provided on the upper portion of the cover body. The buckle tongue can extend into the buckle groove, and the buckle groove can press the side of the buckle tongue against the building body.

[0010] In some possible implementations, the mounting fasteners are mounted on the building structure via expansion screws.

[0011] In some possible implementations, the cover body includes a top cover portion, a slope portion and a breathable portion, the top cover portion and the slope portion have a smooth transition, the top cover portion cooperates with the mounting fasteners, the breathable portion is installed on the building body, the air outlet is provided on the breathable portion, and the width of the breathable portion is greater than that of the top cover portion.

[0012] In some possible implementations, a mounting edge is provided at one outward end of the vent portion, and the mounting edge is connected and fixed to the building body by screws.

[0013] In some possible implementations, the air permeable portion is recessed downward toward the air outlet area.

[0014] Compared with the prior art, the present invention has the following advantages: the windshield of the present invention adopts an installation method in which the mounting fasteners and the cover body cooperate, so that when the cover body is pressed, the upper part of the cover body only needs to be fastened into the mounting fasteners to fix the upper part, and then the lower part of the cover body needs to be installed and fixed to complete the installation and fixation of the entire windshield. The air outlet is provided at the lower part of the cover body to prevent rainwater from entering, and the insect net installed on the air outlet can effectively prevent mosquitoes or debris from being sucked into the wind, thereby improving the protection effect.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] Reference Figures 1 to 3 The windproof cover shown is installed outside the ventilation channel 10, and includes a mounting fastener 20, a cover body 30 and an insect-proof net 40. The mounting fastener 20 is installed on the area of ​​the building body located on the upper side of the ventilation channel 10; the cover body 30 is installed outside the air outlet end of the ventilation channel 10, the upper part of the cover body 30 cooperates with the mounting fastener 20, and the lower part is fixed to the area of ​​the building body located on the lower side of the ventilation channel 10 by screws; the lower part of the cover body 30 is provided with an air outlet 31; the insect-proof net 40 is installed on the air outlet 31.

[0022] The mounting fasteners 20 and the cover 30 are both made of aluminum, which facilitates stamping and integral molding. In this application, the side of the cover 30 to be installed needs to be fully aligned with the wall surface of the building to prevent rainwater leakage. Therefore, during installation, the area where the top of the cover 30 mates with the mounting fasteners 20 can be secondary sealed with sealant to improve sealing.

[0023] In some possible implementations, to facilitate later removal and replacement of the insect-proof net 40, an aluminum pressure plate 32 is provided around the periphery of the air outlet 31 of the cover body 30. The aluminum pressure plate 32 presses the outer edge of the insect-proof net 40 against the cover body 30. The aluminum pressure plate 32 is connected to the cover body 30 via aluminum welding nails 38.

[0024] In the above-described embodiment, to facilitate installation, the mounting fastener 20 is Z-shaped, with a mounting structure formed between its upper end and the main structure. More specifically, the mounting fastener 20 is provided with a buckle slot 21, and the upper portion of the cover 30 is provided with a buckle tongue 33. The buckle tongue 33 can extend into the buckle slot 21, and the buckle slot 21 can press the side of the buckle tongue 33 against the main structure. In fact, the buckle slot 21 is the structure formed between the mounting fastener 20 and the main structure. In addition, the end of the buckle tongue 33 is provided with a protrusion structure. The main purpose of this protrusion structure is to facilitate the stable buckling between the buckle tongue 33 and the buckle slot 21.

[0025] In some possible implementations, in order to achieve stable installation, the installation fastener 20 is installed on the building body through expansion screws.

[0026] See also Figure 2 In one embodiment of the present application, the cover body 30 includes a top cover portion 34, a slope portion 35, and a vent portion 36. The top cover portion 34 and the slope portion 35 have a smooth transition. The top cover portion 34 cooperates with the mounting fastener 20. The vent portion 36 is mounted on the building body. The air outlet 31 is provided on the vent portion 36. The width of the vent portion 36 is greater than that of the top cover portion 34. In order to facilitate drainage on the side of the cover body 30, the slope portion 35 covers three sides of the cover body 30. Of course, in some embodiments, only the side facing the ventilation channel 10 has the slope portion 35, and the remaining two sides are completely vertical.

[0027] In some possible implementations, in order to facilitate installation, a mounting edge 37 is provided at one outward end of the vent portion 36 , and the mounting edge 37 is connected and fixed to the building body by screws.

[0028] In some possible implementations, in order to facilitate the discharge of water vapor condensed on the cover body 30, the air permeable portion 36 is recessed downward toward the air outlet 31 area. Such a design is conducive to the discharge of condensed water.

[0029] The windshield is installed by using the mounting fasteners 20 and the cover body 30. When the cover body 30 is installed, the upper portion of the cover body 30 can be fixed by simply snapping it into the mounting fasteners 20. Then, the lower portion of the cover body 30 can be installed and fixed to complete the installation and fixation of the entire windshield. An air outlet 31 is provided at the lower portion of the cover body 30 to prevent rainwater from entering.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
