Description

Technical Field

[0001] The utility model relates to the technical field of air duct equipment, in particular to a bite connection piece in an air duct air outlet. Background Art

[0002] Ducts are piping systems used for air transportation and distribution. They come in two types: composite ducts and inorganic ducts. Based on their cross-sectional shape, ducts can be categorized as circular, rectangular, and oblate. Circular ducts offer the lowest resistance but are the tallest and most complex to manufacture, so rectangular ducts are the most commonly used. Based on their material, ducts can be categorized as metal, composite, and polymer.

[0003] However, in the prior art, most of the existing methods for installing air vents on air ducts are riveted to ensure that the air vents are stably installed on the air ducts. However, if the air vents are to be installed more tightly on the air ducts, multiple rivets need to be implanted at the connection and installation points of the air vents using a rivet gun, which makes the installation process of the air vents more cumbersome and time-consuming. Utility Model Content

[0004] The purpose of the present invention is to solve the shortcomings in the prior art: if the air outlet is to be installed more tightly on the air duct, it is necessary to use a rivet gun to implant multiple rivets at the connection and installation of the air outlet, which makes the installation process of the air outlet more cumbersome and time-consuming.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an inner bite connector of an air duct outlet, comprising an air duct body, a mounting opening provided on the surface of the air duct body, and a U-shaped inner bite connector fixedly connected to the inner surface of the air duct body at the edge of the mounting opening, a clamping block fixedly connected to one side surface of the U-shaped inner bite connector, a clamping groove provided on the inner surface of the air duct body on one side of the U-shaped inner bite connector, and the clamping block is connected by clamping with the clamping groove, the air duct body is placed at the mounting opening, and a bite plate surface is fixedly connected to the top edge of the air duct body, and the bite plate surface is clamped and connected at the bending gap on the U-shaped inner bite connector.

[0006] As a preferred embodiment, the size of the bending gap on the U-shaped inner bite connector is adapted to the size of the bite plate surface.

[0007] As a preferred embodiment, a filter screen is provided at one end of the air outlet body, and fixing plates are fixedly connected below both side edges of the filter screen, the fixing plates are penetrated by bolts, and the bolts are threadedly connected to the air outlet body.

[0008] As a preferred embodiment, a limiting plate is fixedly connected to the inner surface of the tuyere body.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] The U-shaped inner bite connector is then snapped into place to allow the user to fold the U-shaped inner bite connector and the bite plate outwards, allowing the air vent body to be tightly mounted on the air duct body. The installation process is also relatively simple, which effectively improves the installation efficiency of the air vent body. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1-4The U-shaped inner bite connector 3 is fixedly connected to the inner surface of the duct body 1 at the edge of the mounting opening 2, and a clamping block 4 is fixedly connected to one side surface of the U-shaped inner bite connector 3. A clamping groove 5 is provided on the inner surface of the duct body 1 on one side of the U-shaped inner bite connector 3, and the clamping block 4 is engaged with the clamping groove 5. When the U-shaped inner bite connector 3 is hit and folded outward, the clamping block 4 will be engaged at the clamping groove 5, thereby ensuring the stability of the U-shaped inner bite connector 3 after folding and reducing its After folding, the edge will curl up. The air vent body 6 is placed at the installation port 2, and a bite plate 7 is fixedly connected to the top edge of the air vent body 6. The bite plate 7 is engaged at the bending gap on the U-shaped inner bite connector 3. When the air vent body 6 is installed vertically upward at the installation port 2 of the air duct body 1, the bite plate 7 will be engaged at the bending gap of the U-shaped inner bite connector 3. Then put your hand into the opening of the air vent body 6 and enter the inside of the air duct body 1, and hit the U-shaped inner bite connector 3 to make the U-shaped inner bite connector 3 and the bite plate 7 fold outward, so that the air vent body 6 can be installed quickly and tightly on the air duct body 1.

[0020] Example 2

[0021] like Figure 1-4 As shown, the size of the bending gap on the U-shaped inner bite connector 3 is adapted to the size of the bite plate surface 7, which makes it convenient for the bite plate surface 7 to be fully connected to the bending gap on the U-shaped inner bite connector 3. A filter screen plate 8 is provided at one end of the air outlet body 6. The filter screen plate 8 plays the role of filtering external impurities, effectively preventing external impurities from entering the air duct body 1 through the air outlet body 6, and a fixing plate 9 is fixedly connected to the lower sides of the edges of both sides of the filter screen plate 8. The fixing plate 9 is penetrated by a bolt 10, and the bolt 10 is threadedly connected to the air outlet body 6. With the help of the fixing plate 9 and the bolt 10, the filter screen plate 8 is conveniently installed on the air outlet body 6 more firmly. A limiting plate 11 is fixedly connected to the inner surface of the air outlet body 6, and the filter screen plate 8 is moved and limited by the limiting plate 11, so that the through hole on the fixing plate 9 and the threaded hole on the air outlet body 6 are aligned, which is convenient for the subsequent installation of the bolt 10.

[0022] Working principle:

[0023] like Figure 1-4When the vent body 6 is unable to move upward, the user inserts the striking tool into the opening of the vent body 6 and then strikes the U-shaped inner bite connector 3, so that the U-shaped inner bite connector 3 and the bite plate surface 7 are folded outward, and the clamping block 4 is stuck in the clamping groove 5, completing the installation of the vent body 6 on the duct body 1. Then, the filter screen 8 is taken out and pushed inward from the opening of the vent body 6. After being blocked by the limit plate 11 during the pushing process, the filter screen plate 8 is supported by one hand, and the bolt 10 is rotated and twisted into the fixing plate 9 and the vent body 6 with the other hand to complete the installation of the filter screen plate 8 on the vent body 6.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
