Description

Technical Field

[0001] This utility model relates to the field of fire damper technology, and specifically to a fire damper installation structure. Background Technology

[0002] A fire damper is a type of valve that uses a shape memory alloy for temperature control and closes by gravity and a spring mechanism.

[0003] In the existing technology, if the exhaust fan is installed on the ceiling, the space above the ceiling is usually narrow and the operating space is limited. In actual installation, it is usually operated by only one person. The installer needs to stand on a ladder, hold the fire damper with one hand, and use the other hand to align and tighten the screws and nuts in the mounting holes. Then, four sets of screws and nuts are used to fix the mounting bracket.

[0004] However, existing fire dampers require four sets of screws and nuts to secure them to the ventilation fan without any pre-fixation, making the operation extremely difficult. To simplify the installation process, the ventilation fan must be disassembled first, and the fire damper assembled with it before the overall installation. This process is cumbersome, increasing both installation time and labor costs. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, an installation structure for a fire damper is provided, comprising: an air duct assembly 1, a fixing member 2, and a fire damper main frame 3; the air duct assembly 1 has an installation part 11 at its air inlet end, and the installation part 11 has fixing holes 12; the fixing member 2 is disposed on the first side of the installation part 11, and the fixing member 2 has a plurality of pre-fixing structures 21 for mounting fasteners; the fire damper main frame 3 is disposed on the second side of the installation part 11, and the fire damper main frame 3 has a plurality of mounting holes 32 for mounting fasteners.

[0034] Beneficial effects: During installation, the fixing member 2 is first installed on the first side of the mounting part 11 of the air duct assembly 1. A fastener is then passed through the fixing hole 12 and connected to the pre-fixing structure 21, fixing the fixing member 2 to the mounting part 11. Next, the fire damper main frame 3 is connected to the second side of the mounting part 11, and then fasteners are sequentially passed through the mounting hole 32 and the fixing hole 12 to connect to the pre-fixing structure 21, thus fixing the fire damper main frame 3 and the mounting part 11. No nuts are required throughout the process, greatly improving the convenience and efficiency of installation. The fire damper installation structure provided in this embodiment solves the problem of difficult fire damper installation in the prior art.

[0035] In one embodiment, the pre-fixing structure 21 is configured as a hole-like structure with built-in threads, and the fastener is configured as a bolt. The pre-fixing structure 21 can replace a nut, and the bolt is fixedly connected to the built-in threads of the pre-fixing structure 21, which can improve the convenience of installation and construction efficiency. Alternatively, as an alternative embodiment, the pre-fixing structure 21 can also be configured as a snap-fit ​​structure, and the fastener can be configured as a snap-fit ​​component.

[0036] Specifically, the pre-fixed structure 21 is configured as a flanged hole with internal threads.

[0037] In one embodiment, the mounting hole 32 is an elongated hole. The elongated hole allows the fire damper main frame 3 to adapt to different installation dimensions of the air duct assembly 1, improving the versatility of the components and assembly reliability. Alternatively, as an alternative embodiment, the mounting hole 32 can also be a circular hole.

[0038] In one embodiment, a mounting plate 31 is provided at one end of the fire damper main frame 3 near the air duct assembly 1. The mounting plate 31 is configured as a folded edge structure extending outward from the fire damper main frame 3, and the mounting hole 32 is provided on the mounting plate 31. The mounting part 11 is configured as a folded edge structure extending outward from the air duct assembly 1. During installation, the mounting plate 31 and the mounting part 11 of the folded edge structure abut against each other, facilitating the alignment of the mounting hole 32 with the fixing hole 12. Alternatively, as an alternative embodiment, the mounting part 11 and the mounting plate 31 can also be configured as straight plate structures extending along the central axis of the fire damper main frame 3.

[0039] In one embodiment, the main frame 3 of the fire damper has a square cross-section, and two sets of mounting plates 31 are symmetrically arranged. These two sets of mounting plates 31 meet the installation and fixing requirements of the main frame 3 of the fire damper while reducing costs and construction work. Alternatively, as an alternative embodiment, the main frame 3 of the fire damper can also have a circular cross-section, with the mounting plates 31 arranged circumferentially along the main frame 3 of the fire damper.

[0040] In one embodiment, the mounting plate 31 is further provided with a clearance hole 33 and two mounting holes 32. After the fixing member 2 and the air duct assembly 1 are fixedly connected by a fastener, the mounting plate 31 of the fire damper main frame 3 is pressed against the mounting part 11. The clearance hole 33 can avoid the fastener, so that the mounting plate 31 fits against the mounting part 11. Then, four fasteners are locked into the fixing hole 12, the mounting hole 32 and the pre-fixing structure 21 to fix the mounting plate 31 and the mounting part 11. In addition, as an alternative embodiment, the mounting hole 32 can be set to three or more according to the actual installation design needs.

[0041] In one embodiment, a limiting member 34 is provided at one end of the fire damper main frame 3 near the air duct assembly 1. One limiting member 34 is provided at each end of the mounting plate 31, and the limiting member 34 is used to embed into the air duct assembly 1. The limiting member 34 can limit the fire damper main frame 3, preventing displacement between the fire damper main frame 3 and the air duct assembly 1 during use. Alternatively, as an alternative embodiment, the limiting member 34 can be omitted, and locking and limiting can be achieved solely through the fixed connection between the mounting plate 31 and the mounting part 11.

[0042] In one embodiment, the fastener 2 is configured as a bent structure. The bent structure strengthens the fastener 2, thereby improving the stability of the fire damper installation. Alternatively, as an alternative embodiment, the fastener 2 can be configured as a straight plate structure.

[0043] In one embodiment, a flange 35 is fitted onto the end of the fire damper main frame 3 furthest from the air duct assembly 1, and the flange 35 and the fire damper main frame 3 are connected by a fastener 2. The flange 35 facilitates installation work on the end of the fire damper main frame 3 furthest from the air duct assembly 1. Alternatively, as an alternative embodiment, the flange 35 can be omitted, and a folded edge structure can be provided on the end of the fire damper main frame 3 furthest from the air duct assembly 1.

[0044] In one embodiment, the air duct assembly 1 is configured as a ventilation fan. The ventilation fan can meet the indoor ventilation requirements. Alternatively, as an alternative implementation, the air duct assembly 1 can also be configured as a central air conditioning duct, a smoke exhaust duct, or other ventilation and smoke exhaust assembly with fireproof ventilation requirements.

[0045] In one embodiment, the ventilation fan includes: a housing with an internal cavity, an air inlet on the side of the housing near the main frame 3 of the fire damper, and a mounting part 11 disposed around the air inlet; a fan assembly disposed within the cavity of the housing, with the air inlet end of the fan assembly connected to the air inlet; and an exhaust pipe disposed on the housing, connected to the air outlet end of the fan. Under the action of the fan assembly, air passes through the main frame 3 of the fire damper and enters the housing from the air inlet, and is then discharged outward through the exhaust pipe.

[0046] How to use: When both the air duct assembly 1 and the fire damper are newly installed, first install the main frame 3 of the fire damper on the air duct assembly 1 using fasteners through the fixing piece 2. For the model with lights, install the LED extension cable. Then, install the air duct assembly on the crossbeam through the bracket. Insert the flange 35 into the main frame 3 of the fire damper and fix it with screws from the side. Finally, install the panel on the ceiling.

[0047] With the air duct assembly 1 already installed, first fix the fixing part 2 to the mounting part 11 of the air duct assembly 1 with a screw. Then, lift the main frame 3 of the fire damper with one hand until the mounting plate 31 presses against the mounting part 11. At the same time, use the other hand to connect the fixing hole 12, the mounting hole 32 and the pre-fixing structure 21 with four screws respectively. The pre-fixing structure 21 has built-in threads and does not require nuts for fixing.

[0048] Two convenient installation options are provided, which can fully adapt to the needs of new decoration scenarios and the addition of fire dampers to the existing air duct components 1, significantly broadening the application scope and reducing the installation complexity.

[0049] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
