Description

Technical Field

[0001] This utility model belongs to the technical field of fire extinguisher boxes, and specifically relates to a fire extinguisher box. Background Technology

[0002] In modern building fire safety systems, fire boxes are core devices for storing key fire-fighting equipment such as fire extinguishers, fire hoses, and water guns. Their reliability is directly related to the efficiency of emergency response in the event of a sudden fire.

[0003] However, in practical applications, the doors of fire extinguisher boxes are easily affected by environmental factors and their performance deteriorates because they are usually closed and rarely opened. For example, in humid underground garages, rainy southern regions, or industrial environments with corrosive gases, the metal parts such as the door and locks are prone to corrosion, causing them to become stuck or even jammed. The difficulty in opening the cabinet door due to aging or corrosion can have serious consequences in emergencies such as fires. When firefighters or on-site personnel need to quickly access fire-fighting equipment, if the door cannot be opened smoothly, extra time is often required for dismantling or repair. This undoubtedly delays the initial firefighting time. The fire spreads extremely quickly, and every second of delay can lead to the fire expanding. This not only increases the difficulty of firefighting and rescue but also makes it easier to cause more casualties and property damage, seriously affecting the effectiveness of fire safety assurance.

[0004] Therefore, this utility model provides a fire box to solve the above problems. Utility Model Content

[0017] Example 1: A fire extinguisher box, such as Figures 1-7 As shown, the device includes a housing 1 with a door 2. Both the housing 1 and the door 2 are equipped with two sets of quick-release components 4, enabling rapid opening of the door 2 in emergencies. This avoids difficulties caused by corrosion of traditional locks, saving time for rescue efforts. Each quick-release component 4 includes two U-shaped brackets 41 fixedly installed on one side of the inner wall of the housing 1. The quick-release components 4 also include two positioning shafts 44 fixedly installed on the inner side of the door 2. A pressure rod 45 is rotatably mounted on the outer surface of each positioning shaft 44. One end of the pressure rod 45 is hinged to a connecting block 43, and the end of the connecting block 43 is hinged to a connecting plate 8. The end of the connecting plate 8 is hinged to a wedge block 42. The wedge block 42 matches the U-shaped bracket 41. This structure utilizes the wedge block 42 and the U-shaped bracket 41... The engagement of the shaped card holder 41 ensures reliable locking, while it can be easily separated by lever action when opening. It also serves as a replacement for a hinge, improving ease of operation. The other end of the pressure rod 45 is equipped with a control component, and two sets of elastic components 3 are provided on the inner wall of the housing 1 to assist in opening the door.

[0018] The door 2 has a long, narrow groove 22 to guide and restrict the movement of the connecting rod 46, ensuring that the connecting rod 46 moves along a preset trajectory. The control component includes a connecting rod 46 hinged to the other end of the pressure rod 45, and the connecting rod 46 passes through the groove 22. A pull ring 47 is fixedly installed at the end of the connecting rod 46. The force is effectively transmitted to the pressure rod 45 through the connecting rod 46, so that the operator can easily drive the quick-release component 4 from the outside of the door 2, which is convenient and labor-saving.

[0019] Two sets of latches 5 are fixedly installed on one side of the door 2. The two sets of elastic components 3 include two sets of mounting seats 31 installed on the inner wall of the box body 1 at the positions corresponding to the latches 5 by fasteners. Each set of mounting seats 31 has a mounting groove 33, and a spring 34 is fixedly installed in the mounting groove 33. The end of the spring 34 is fixedly connected to a movable rod 32. The spring 34 has elastic potential energy and releases energy when the door 2 is opened. The movable rod 32 fixedly connected to the end applies a pushing force to the latches 5 to assist the door 2 in opening and reduce the opening resistance.

[0020] Two sets of magnetic plates 6 are fixedly installed on the inner wall of the box body 1. The two sets of magnetic plates 6 can attract the box door 2 to the box body 1 in normal state, enhance the sealing and stability of the box door 2 when closed, prevent the box door 2 from being opened accidentally, and avoid the corrosion problem of traditional locks, thus reducing maintenance costs.

[0021] The door 2 is provided with a groove 21, which provides a convenient point of force for the operator to open the door 2, making it easier to grip and pull, and making the opening operation more convenient and labor-saving.

[0022] Both sets of mounting bases 31 are fixedly connected to the housing 1 by multiple sets of bolts 35. This connection method is stable and reliable, ensuring that the mounting bases 31 do not loosen or shift when the spring 34 is under force, ensuring the normal operation of the elastic component 3, and facilitating the disassembly and maintenance of the mounting bases 31.

[0023] Among them, a limit plate 7 is fixedly installed on the side wall of the box door 2 to limit the connection block 43 and prevent the wedge block 42 from accidentally disengaging from the U-shaped card seat 41 due to excessive rotation of the connection block 43.

[0024] The inner wall of the U-shaped bracket 41 is coated with polytetrafluoroethylene, which reduces the friction between the wedge block 42 and the U-shaped bracket 41, making their engagement and disengagement smoother. At the same time, it prevents the inner wall of the U-shaped bracket 41 from rusting, extends its service life, and ensures the long-term reliable operation of the quick-release assembly 4.

[0025] Working principle: In the normally closed state, the door 2 is tightly attracted to the inner wall of the cabinet 1 by two sets of magnetic plates 6, forming an initial sealing state, which also acts as a substitute for the hinge. At this time, the quick-release component 4 is in the locked state: the wedge block 42 is embedded in the U-shaped bracket 41 under the force of the pressure rod 45. Since the inclined surface of the wedge block 42 and the inner side of the U-shaped bracket 41 interlock with each other, and the limiting plate 7 resists and limits the connecting block 43, it can effectively prevent the wedge block 42 from accidentally disengaging, thereby enhancing the closing stability of the door 2. At the same time, the two sets of latches 5 on one side of the door 2 are inserted into the mounting groove 33 of the elastic component 3, pushing the movable rod 32 to compress the spring 34, so that the spring 34 is in an energy storage state, storing elastic potential energy for subsequent door opening.

[0026] When the cabinet door 2 needs to be opened normally, the operator can put their hand into the pull groove 21 on the outer surface of the cabinet door 2 and pull the cabinet door 2 outward. At this time, the attraction force of the magnetic suction plate 6 is overcome, and the compressed spring 34 releases elastic potential energy, pushing the movable rod 32 to apply an outward pushing force to the locking pin 5. Under the combined action of these two forces, the cabinet door 2 can be easily rotated and opened around the rotating structure, realizing convenient access to fire-fighting equipment.

[0027] In case of an emergency where the door 2 is jammed due to aging, corrosion, or other reasons, the quick-release assembly 4 can play a crucial role. The operator pulls the pull ring 47 located on the outside of the door 2, and the connecting rod 46 moves along the length of the limiting groove 22, causing the pressure rod 45 to rotate around the positioning shaft 44. Under the action of the lever principle, the end of the pressure rod 45 away from the pull ring 47 tilts upward, and drives the wedge block 42 to move synchronously through the connecting block 43, causing the wedge block 42 to disengage from the U-shaped bracket 41. At this time, the locking state of the quick-release assembly is released, and the door 2 can be opened quickly.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
