Technical Field
[0001] This utility model relates to the technical field of dry powder fire extinguishing devices, and in particular to a suspended dry powder fire extinguishing device. Background Technology
[0002] Suspended dry powder fire extinguishing systems play a crucial role in fire safety systems across various locations. From densely populated shopping malls and office buildings to flammable and explosive warehouses and factories, and relatively enclosed underground parking lots, suspended dry powder fire extinguishing systems can respond rapidly in the event of a fire, releasing dry powder extinguishing agent to effectively control the spread of the fire and buy valuable time for evacuation and fire rescue. The spatial layout, building structure, and fire risk characteristics of different locations vary, requiring suspended dry powder fire extinguishing systems to have flexible installation and commissioning capabilities to ensure maximum fire extinguishing effectiveness in the optimal location.
[0003] Traditional suspended dry powder fire extinguishing devices have a relatively fixed structural design. They are usually fixed directly to the ceiling or wall using simple hooks or brackets. The fire extinguisher is hung directly on the hook by its own suspension ring. The bracket structure is generally welded from angle steel or channel steel and is customized according to the size of the fire extinguisher. The bracket is fixed to the wall or ceiling with bolts.
[0004] However, traditional suspended dry powder fire extinguishing devices have the problem of difficulty in flexibly adjusting the suspension height of the fire extinguishers according to needs. In practical application scenarios, the spatial height and the arrangement of goods vary in different places. In large warehouses, the height of stored goods varies, and taller shelves can obstruct the extinguishing range of fire extinguishers suspended at lower heights. Traditional fixed-height fire extinguishing devices cannot be adjusted in time, resulting in ineffective coverage of the fire source when a fire occurs. Therefore, a suspended dry powder fire extinguishing device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a suspended dry powder fire extinguishing device, which aims to improve the problem in the prior art that it is difficult to flexibly adjust the suspension height of the fire extinguisher according to the needs, resulting in the inability to effectively cover the fire source when a fire occurs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A suspended dry powder fire extinguishing device includes a suspension frame and a fire extinguisher. A baffle is fixedly connected inside the suspension frame. A valve is provided at the bottom of the fire extinguisher. A nut is fixedly connected to the top of the fire extinguisher. An adjustment component is provided inside the suspension frame. An installation plate is fixedly connected to the top of the suspension frame. A connecting component is provided inside the installation plate.
[0008] The adjustment assembly includes a threaded post that is slidably connected inside the suspension frame and threadedly connected inside the nut. A threaded sleeve is rotatably connected inside the suspension frame, and the threaded post is threadedly connected inside the threaded sleeve. A knob is fixedly connected to the outer wall of the threaded sleeve.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes a pin and a hollow column. The outer wall of the pin is fixedly connected to the inside of the mounting plate, and the top end of the hollow column is fixedly connected to the bottom end of the pin.
[0011] As a further description of the above technical solution:
[0012] The pin is slidably connected to a sliding column inside the hollow column.
[0013] As a further description of the above technical solution:
[0014] A limiting post is fixedly connected to the top of the sliding post, and a tapered post is fixedly connected to the outer wall of the limiting post. The tapered post is slidably connected inside the pin.
[0015] As a further description of the above technical solution:
[0016] The pin has a sliding bead inside, and the bead is in contact with the tapered post.
[0017] As a further description of the above technical solution:
[0018] A spring is fitted on the outer wall of the sliding column, and the bottom end of the spring is fixedly connected to the inside of the hollow column.
[0019] As a further description of the above technical solution:
[0020] A connecting ring is fixedly connected to the outer wall of the sliding column, and the top end of the spring is fixedly connected inside the connecting ring.
[0021] As a further description of the above technical solution:
[0022] A connecting column is fixedly connected to the bottom end of the sliding column, and a handle is fixedly connected to the bottom end of the connecting column.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by turning the knob to drive the threaded sleeve to rotate, the threaded column slides up and down in the suspension frame. The threaded column drives the nut and the fire extinguisher to adjust the height, which realizes the effect of flexibly adjusting the suspension height of the fire extinguisher according to the needs. This solves the problem that it is difficult to flexibly adjust the suspension height of the fire extinguisher according to the needs, resulting in the inability to effectively cover the fire source when a fire occurs, thereby improving the applicability of the suspended dry powder fire extinguishing device.
[0025] 2. In this utility model, the handle drives the connecting column to move, which in turn drives the sliding column to slide within the hollow column and the pin. The sliding column compresses the connecting ring spring, simultaneously causing the limiting column and the conical column to slide and release the retaining beads. After the hanging bracket mounting plate is aligned with the mounting surface and the pin is inserted, releasing the handle causes the spring to return and reset all components. The retaining beads then engage with the pre-drilled holes to complete the fixation, achieving easy assembly and disassembly of the hanging bracket. This solves the problem of traditional suspended dry powder fire extinguishing devices having difficult-to-remove hanging brackets after installation, and the inability to easily adjust the installation position during site layout changes or device maintenance, thereby improving the flexibility of suspended dry powder fire extinguishing devices.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a suspended dry powder fire extinguishing device, comprising a suspension frame 1 and a fire extinguisher 2. A baffle 3 is fixedly connected inside the suspension frame 1. A valve 4 is provided at the bottom of the fire extinguisher 2. The valve 4 is a key component for controlling the outflow of dry powder inside the fire extinguisher 2. A nut 5 is fixedly connected to the top of the fire extinguisher 2. The nut 5 is connected to the adjustment component of the suspension frame 1 by threads to ensure the stability of the fire extinguisher 2 in the suspension frame 1. An adjustment component is provided inside the suspension frame 1. An mounting plate 9 is fixedly connected to the top of the suspension frame 1. A connecting component is provided inside the mounting plate 9.
[0033] The adjustment assembly includes a threaded post 6, which is slidably connected inside the suspension bracket 1 and threadedly connected inside the nut 5 to adjust the fixed position of the fire extinguisher 2. A threaded sleeve 7 is rotatably connected inside the suspension bracket 1, and the threaded post 6 is threadedly connected inside the threaded sleeve 7. A knob 8 is fixedly connected to the outer wall of the threaded sleeve 7. The user can rotate the knob 8 to drive the rotation of the threaded sleeve 7, thereby adjusting the position of the threaded post 6 and thus adjusting the hanging height of the fire extinguisher 2.
[0034] Reference Figures 1-3 The connecting assembly includes a pin 10 and a hollow column 11. The outer wall of the pin 10 is fixedly connected to the inside of the mounting plate 9, and the top end of the hollow column 11 is fixedly connected to the bottom end of the pin 10. The function of the pin 10 is to form a connecting structure together with the hollow column 11 to support the stable hanging of the fire extinguisher 2. A sliding column 12 is slidably connected inside the pin 10 and is slidably connected to the inside of the hollow column 11. A limiting column 13 is fixedly connected to the top end of the sliding column 12, and a conical column 14 is fixedly connected to the outer wall of the limiting column 13. The conical column 14 is slidably connected inside the pin 10, and a retaining ball is slidably connected inside the pin 10. 15. The locking bead 15 and the conical column 14 are in contact. When the sliding column 12 slides, the locking bead 15 and the conical column 14 cooperate to perform disassembly and assembly operations. A spring 16 is sleeved on the outer wall of the sliding column 12. The bottom end of the spring 16 is fixedly connected to the inside of the hollow column 11. A connecting ring 17 is fixedly connected to the outer wall of the sliding column 12. The top end of the spring 16 is fixedly connected to the inside of the connecting ring 17. The function of the spring 16 is to provide the necessary restoring force to ensure that the sliding column 12 can automatically return to the initial position after adjustment. A connecting column 18 is fixedly connected to the bottom end of the sliding column 12. A handle 19 is fixedly connected to the bottom end of the connecting column 18.
[0035] Working principle: When adjusting the suspension height of the fire extinguisher 2 during the use of this suspended dry powder fire extinguishing device, first turn the knob 8 to make the threaded sleeve 7 rotate inside the suspension frame 1 and on the outer wall of the threaded column 6. This causes the threaded column 6 to slide up and down inside the suspension frame 1. The threaded column 6 is subjected to force, which drives the nut 5 at the bottom to move up and down. This allows the nut 5 to adjust the fire extinguisher 2. At the same time, the threaded relationship between the nut 5 and the threaded column 6 makes it easy for the fire extinguisher 2 to be quickly connected and disconnected from the suspension frame 1, thereby achieving the effect of adjusting the suspension height of the fire extinguisher 2 according to needs.
[0036] When it is necessary to disassemble or assemble the suspension bracket 1, first place the suspension bracket 1 in the installation position. At this time, pull the handle 19 to move the connecting column 18. The connecting column 18 causes the sliding column 12 to slide inside the hollow column 11 and the pin 10. The sliding column 12 causes the connecting ring 17 on the outer wall to move. The connecting ring 17 is compressed by the force on the spring 16 at the bottom end. At the same time, the sliding column 12 causes the limiting column 13 at the top end and the tapered column 14 on its outer wall to slide inside the pin 10, so that the tapered column 14 closes the pin 10. The locking ball 15 is released, allowing it to slide into the pin 10 and lock onto the outer wall of the limiting post 13. At this time, the mounting plate 9 at the top of the suspension bracket 1 is attached to the mounting surface, and the pin 10 is inserted into the reserved hole on the mounting surface. Then, the handle 19 is released, and the spring 16 releases the force and rebounds, thereby driving the connecting ring 17 and the sliding post 12 to reset. This causes the limiting post 13 to drive the conical post 14 to squeeze the locking ball 15. The locking ball 15 is forced to slide out of the pin 10 and lock into the reserved hole to complete the fixation, thus achieving the effect of easy disassembly and assembly of the suspension bracket 1.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
