[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1 、 2 As shown in Figure 3, a flange for a ventilation pipe 7 that is easy to install includes a flange frame, a sealing strip 3, and a buckle. The flange frame includes a mounting frame 1 and a connecting plate 2. Since the shape of existing ventilation pipes 7 is mostly rectangular, the mounting frame 1 in this device is preferably a rectangular column. The two ends of the mounting frame 1 are connected and are used to be sleeved on the outside of one end of the ventilation pipe 7. The side wall of the mounting frame 1 is provided with a plurality of mounting holes 101 for bolting the mounting frame 1 to the ventilation pipe 7.

[0025] Specifically, the corners of the rectangular installation frame 1 are further provided with connecting corners 4 for reinforcing the structure of the installation frame 1;

[0026] The connecting plate 2 is an annular frame that surrounds one end of the mounting frame 1 and is vertically connected to the outer edge of the opening at one end of the mounting frame 1. It is provided with a plurality of mounting holes 101. When adjacent flange frames are connected, the mounting holes 101 of the connecting plates 2 on both sides are correspondingly arranged and connected by bolts. The outer edge of the connecting plate 2 is also provided with a vertical rib to facilitate snap-on connection.

[0027] Specifically, when used in a low-temperature and low-humidity ventilation environment, the material of the connecting plate 2 and the mounting frame 1 is plastic, preferably ABS plastic, and the connection between the two is preferably adhesive, which can effectively reduce costs while ensuring the connection strength.

[0028] The sealing strip 3 is arranged around the side of the connecting plate 2 away from the mounting frame 1. The material of the sealing strip 3 is preferably sponge rubber. When adjacent flange frames are connected, the sponge rubber between them is squeezed and compressed by the flange frames on both sides, which can provide good sealing performance.

[0029] The buckle is preferably a plastic buckle 5, and its material is preferably ABS plastic. When adjacent flange frames are connected, the two sides of the buckle are respectively connected to the connecting plates 2 on both sides to further strengthen the connection strength of the device.

[0030] Example 2

[0031] like Figure 4As shown, when used in a high temperature and high humidity ventilation environment, the material of the connecting plate 2 and the mounting frame 1 is selected to be metal, preferably aluminum alloy, and the connection between the two is preferably welding connection, which can ensure that they have good connection strength;

[0032] The material of the sealing strip 3 is preferably silicone rubber, which has good high temperature resistance and can maintain a stable sealing effect in a high temperature environment;

[0033] The clip is preferably a metal clip 6, which is N-shaped and has a screw hole on one side. When adjacent flange frames are connected, the two sides of the clip are respectively connected to the connecting plates 2 on both sides, and then the stud is passed through the screw hole and one end is screwed inward and pressed on the connecting plate 2 to further strengthen the connection strength of the device.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent replacements, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
