Description

Technical Field

[0001] This utility model relates to the field of fire-resistant air duct technology, specifically a fire-resistant air duct that is easy to connect and install. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. There are two types: composite air ducts and inorganic air ducts. Composite air ducts are the most representative. They can be classified according to cross-sectional shape and material. Stainless steel air duct fabrication involves applying sealant to gaps such as seams, rivet seams, and the four corners of flanges. Before applying sealant, surface dust and oil should be removed. According to cross-sectional shape, air ducts can be divided into various types such as circular air ducts, rectangular air ducts, and flat oval air ducts. Among them, circular air ducts have the lowest resistance but the largest height dimension and are more complex to manufacture, so rectangular air ducts are mainly used. According to material, air ducts can be divided into metal air ducts, composite air ducts, polymer air ducts, and fire-resistant magnesium crystal metal composite refractory air ducts, which are fire-resistant air ducts that integrate metal layers, heat insulation layers, and reinforcement layers.

[0003] In response, Chinese patent application number CN216715440U discloses a fire-resistant duct that facilitates docking and installation. The duct includes a duct shell, an inner lining fixed to the inside of the shell, and a fire-resistant material layer fixed to the outside of the inner lining. A docking structure is provided on the outside of the duct shell, comprising a first C-shaped steel, a second C-shaped steel, an L-shaped limiting strip, a double-slip sleeve, a single-slip sleeve, and a T-shaped limiting block. The first C-shaped steel is fixed to the outside of the duct shell near the upper surface, and the second C-shaped steel is fixed to the outside of the duct shell near the lower surface. The docking structure is located on the outside of the duct shell via the first and second C-shaped steels. This fire-resistant duct, with its docking structure, makes the docking and installation process of the fire-resistant duct more convenient and simple, eliminating the need for multiple screws and reducing the workload and labor intensity of installers.

[0004] However, the existing fire-resistant air ducts are installed and fixed by the cooperation of No. 1 C-shaped steel, No. 2 C-shaped steel, L-shaped limiting strip, double-through sliding sleeve, single-through sliding sleeve and T-shaped limiting block. The existing equipment has many operation steps and the installation process is complicated, which may not greatly improve the installation efficiency.

[0005] Therefore, in order to solve the above problems, a fire-resistant duct that is easy to connect and install is proposed. Utility Model Content

The duct assembly is clamped and fixed by the cooperation of the sliding groove and the slot in the steel ring inside the mechanism. Then, the movable block inside the clamping assembly drives the screw to rotate, thereby causing the first slider to drive the retaining spring to retract, which in turn drives the second slider to drive the clamping plate to clamp and fix the fire-resistant duct, thereby further fixing the duct assembly and improving the service life of the duct assembly.

[0016] 2. A snap-fit ​​mechanism is provided, which can hold the installation pipe to the main body.

[0026] As a further improvement of this utility model, a fixing block 1035 is provided on the outer side of the steel ring 1031, and a clamping assembly 104 is fixedly installed on the fixing block 1035. A clamping plate 1036 is movably installed inside the steel ring 1031, and a fire-resistant tube 1037 is provided on the inner side of the clamping plate 1036. By setting this component, the clamping plate 1036 can be moved and clamped by the clamping assembly 104.

[0027] As a further improvement of this utility model, the clamping assembly 104 is provided with a rotating block 1041. A screw 1042 is fixedly installed on one side of the rotating block 1041, and a fixing plate 1044 is provided on one side of the rotating block 1041. A fixing shaft 1043 is fixedly installed on the fixing plate 1044. The screw 1042 passes through the fixing shaft 1043 and is rotatably installed in the fixing plate 1044. By setting this component, the rotating block 1041 can drive the screw 1042 to rotate.

[0028] As a further improvement of this utility model, a movable block 1045 is fixedly installed at one end of the screw 1042. A first slider 1046 is provided on one side of the movable block 1045.

[0031] Working principle: When fire-resistant ducts are needed, the main body 1 and the installation pipe 2 can be quickly aligned and connected by the attraction between the first magnet 102 and the second magnet 202. Then, rotating the installation pipe 2 will cause the fixing rod 2032 in the buckling mechanism 203 to slide in the slide groove 1032 of the fixing mechanism 103 through the pulley 2033. This will drive the movable rod 2035 and the abutment 2036 to slide in the slide groove 1032. When they slide to the designated position, they can be locked in place by the abutment 2036 and the slot 1033. During the locking process, the rotating shaft 2034 and the spring 2037 work together to firmly lock the abutment in the slot 1033, thus connecting the installation pipe 2 and the main body. 1. Engage the clamping assembly 104 by rotating block 1041 within the twisting clamping assembly 104. This rotation drives screw 1042 to rotate, which in turn drives movable block 1045 to rotate. The movable block 1045 then slides the first slider 1046 and snap ring 1047 within the fixed plate 1044. This causes the second slider 1048 to drive clamping plate 1036 to clamp and fix the refractory pipe 1037 within the duct assembly 101. When it is necessary to disassemble the main body 1 and the installation pipe 2, press the pusher block 1034 to remove the abutment block 2036 from the grouting groove 1033. Then, rotate the installation pipe 2 counterclockwise to complete the disassembly. This completes the work.
