Description

Technical Field

[0001] The utility model relates to the technical field of fireproof valves, in particular to a fireproof valve protection mechanism. Background Art

[0002] As we all know, fire dampers are a type of valve that uses temperature control of a memory alloy and is closed by gravity and a spring mechanism. New products also use memory alloys to deform to close the valve. Its function is: when the smoke temperature reaches 280°C, people have basically been evacuated, smoke exhaust is no longer meaningful, and the smoke is already carrying fire, so the valve automatically closes to prevent the fire from spreading. In the past, fire dampers had no protective mechanism and were easily damaged by external forces. Once damaged, it would cause unpredictable consequences, so a protective mechanism was needed.

[0003] However, the existing fire damper protection mechanism is generally fixed by bolts. When the protection mechanism needs to be disassembled, the bolts and the parts need to be disassembled, and a screwdriver matching the bolts needs to be found, which wastes a lot of time.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A fire damper protection mechanism comprises a first protective shell 1, a second protective shell 2 and a connecting mechanism 5, wherein the connecting mechanism 5 comprises a first connecting block 3, a second connecting block 4, a fixed block 15, a slide groove 6, a slider 7, a through groove 8, a slot 9, a movable block 10, a telescopic rod 11 and a clamping block 12, wherein the first connecting block 3 is arranged on the first protective shell 1, the second connecting block 4 is arranged on the second protective shell 2, one end of the fixed block 15 is connected to the first connecting block 3, and the other end of the fixed block 15 passes through the second connecting block 4, The slide groove 6 is provided on the second connecting block 4, the through groove 8 is provided on the fixed block 15, one end of the slider 7 is slidably connected to the slide groove 6, the other end of the slider 7 passes through the through groove 8, the slot 9 is provided on the slider 7, one end of the movable block 10 is hinged to the inner wall of the slot 9, one end of the telescopic rod 11 is connected to the bottom of the movable block 10, the other end of the telescopic rod 11 is connected to one end of the clamping block 12, the other end of the clamping block 12 extends into the second connecting block 4, and two connecting mechanisms 5 are provided.

[0024] When in use, the first protective shell 1 and the second protective shell 2 can be connected through the connecting mechanism 5, and the fire damper to be protected can be placed between the first protective shell 1 and the second protective shell 2. When the fire damper needs to be regularly inspected, first a staff member holds the first protective shell 1 and the second protective shell 2 with his hands, and then another staff member pushes the block 12 on the telescopic rod 11 to separate the block 12 from the second connecting block 4, and then rotates the movable block 10 hinged to the inner wall of the slot 9 to rotate the movable block 10 ninety degrees, and then pushes the slider 7 on the slide groove 6 to separate the slider 7 from the through groove 8, and then lifts the second protective shell 2 upward to separate the fixed block 15 on the first connecting block 3 from the second connecting block 4, so that the first protective shell 1 and the second protective shell 2 can be separated, and then the fire damper can be inspected. This structure connects the first protective shell 1 and the second protective shell 2 through the connecting mechanism 5, avoiding the need to disassemble and assemble the bolts one by one, and avoiding the need to find a specified screwdriver, thereby saving a lot of time and improving work efficiency.
