Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and in particular relates to a suspension connection mechanism and an aerosol fire-extinguishing device. Background Art

[0002] The suspended heptafluoropropane fire extinguishing device has high fire extinguishing efficiency, fast speed, large safety factor, and reliable operation. It uses nitrogen as the driving gas, and the nitrogen filling pressure is 1.6MPa. It is easy to install, with a small amount of engineering work, and does not require window or wall holes and the installation of a large number of pipelines and auxiliary facilities. You only need to hang the device above the protected object. The installation and suspension are generally fixed diagonally through multiple threads.

[0003] However, the fire extinguishing range of the suspended HFC-227ea fire extinguishing device is certain, and the upper hanging connection mechanism has also fixed the HFC-227ea fire extinguishing device. As a result, if the range to be protected is larger than the fire extinguishing range of the installed HFC-227ea fire extinguishing device, multiple HFC-227ea fire extinguishing devices need to be installed, which undoubtedly increases the fire extinguishing cost and has certain limitations. Therefore, we propose a hanging connection mechanism and an aerosol fire extinguishing device. Utility Model Content

[0028] Through the design of the movable connection between the deceleration component 5 and the angle changing component 4, when the angle changing component 4 moves upward too fast, the deceleration component 5 can use its own characteristics to slow down the speed of the angle changing component 4 moving upward.

[0029] A switching component 6, the switching component 6 is movably connected to the angle changing component 4, and the angle changing component 4 is detachably connected to the deceleration component 5 through the switching component 6;

[0030] like Figures 1 to 7 As shown, since the angle changing component 4 is detachably connected to the deceleration component 5 through the switching component 6, the upward movement trajectory of the angle changing component 4 can be changed at will through the switching component 6. Therefore, corresponding changes can be made according to the protection range of the protected object, thereby eliminating the need to add too many aerosol fire extinguishing devices.

[0031] Further, the angle changing component 4 includes an angle plate 403, which is fixedly mounted on the upper surface of the connecting seat 7, an angle groove is provided at the bottom of the suspension connecting plate 3, and a serpentine groove 401 and a serpentine hole are provided on both sides of the angle groove, and sliding rods 402 are detachably connected to both sides of the angle plate 403 through the switching component 6, and two groups of sliding rods 402 are slidably mounted in the serpentine groove 401 and the serpentine hole, respectively, and one group of sliding rods 402 is movably connected to the deceleration component 5;

[0032] It is worth noting that the serpentine groove 401 and the serpentine hole are arranged in the same manner. Figure 2 The serpentine hole is provided to facilitate the connection between the angle plate 403 and the deceleration component 5.

[0033] By means of the design that two sets of sliding rods 402 are respectively slidably installed inside the serpentine groove 401 and the serpentine hole, when the angle plate 403 is connected to the sliding rod 402 and moves upward, the angle plate 403 can swing freely during the upward movement, thereby increasing the fire extinguishing range of the aerosol fire extinguishing device.

[0035] By the design that the circular slider 506 is slidably installed inside the slide groove, when the sliding rod 402 extends the serpentine hole and repeatedly moves left and right, the circular slider 506 cooperates with the slide groove to make the spiral shaft 504 rise steadily, and then cooperates with the spiral blade 505 to slow down the rising speed of the sliding rod 402, so as to effectively ensure the duration of the change of the fire extinguishing range of the aerosol fire extinguishing device, thereby further improving the fire extinguishing effect.

[0036] Furthermore, the switching assembly 6 includes a first screw rod 603 and a second screw rod 604.

[0037] Through the design that the two groups of second expansion plates 13 are arranged on the same horizontal line as the second extrusion block 608, the first screw rod 603 can complete the connection between the angle plate 403 and the two groups of sliding rods 402 by squeezing the two groups of second expansion plates 13 so that the plug-in rod 607 is plugged into the plug-in slot, so that the angle plate 403 can increase the fire extinguishing range of the aerosol fire extinguishing device.
