Description

Technical Field

[0001] The utility model relates to the technical field of fireproof air duct installation, in particular to an installation structure of a fireproof air duct. Background Art

[0002] Fireproof duct is a kind of pipe product used for ventilation and air exchange. It is mainly used in passages, electrical rooms, underground garages and other areas in buildings. Once these areas catch fire, the fire can easily spread due to sufficient oxygen supply, so the role of fireproof duct is very important. In addition to the function of ventilation and air exchange, fireproof duct can also slow down the spread of fire and enhance the fire resistance of buildings.

[0003] The existing Chinese patent announcement number is CN214368243U, and its name is a fireproof duct mounting bracket. Through the cooperation of the pull rod, a manual drive source is provided for the movement of the movable plate. Through the cooperation of the support rod, the movable plate, the first spring, the movable rod, the positioning rod and the positioning block, the elastic potential energy of the first spring facilitates the positioning rod to be quickly fixed with the positioning groove, thereby facilitating the rapid installation of the mounting seat and the fixing seat. The user no longer needs to use other tools to perform tedious installation of the fireproof duct mounting bracket, effectively reducing the installation steps, thereby saving time and effort in the installation process, greatly reducing the user's work intensity, and also effectively improving the user's installation work efficiency, solving the problem that the traditional fireproof duct mounting bracket is not easy to install quickly. Through the cooperation of the limit plate, the fixing rod, and the second spring, the fireproof air duct can be effectively fixed to prevent the fireproof air duct from shaking; through the cooperation of the limit rod and the limit ring, the fixing rod can be effectively limited and fixed to prevent the fixing rod from rebounding; through the cooperation of the first slide groove and the first slider, the limit plate is prevented from position displacement during movement, and the limit plate has a sliding limit function; through the cooperation of the second slide groove and the second slider, the movement of the movable plate is smoother, thereby making the clamping process of the positioning rod and the positioning groove more stable; through the cooperation of the third spring, the elastic potential energy of the third spring makes the fixing of the positioning rod and the positioning groove more firmly, further enhancing the stability of the mounting base during installation.

[0004] However, in this technology, the size of the mounting frame is fixed, and after installation, its height position cannot be adjusted according to needs, so that the installation height of the fireproof air duct cannot be adjusted according to installation requirements. The flexibility of the device is low and the use effect is poor. Therefore, we propose an installation structure for the fireproof air duct to solve the above problems. Utility Model Content
