Description

Technical Field

[0001] The present invention relates to fire extinguisher box technology, in particular to a multifunctional fire extinguisher box. Background Art

[0002] Fire refers to uncontrolled combustion in time or space. Among various disasters, fire is one of the most frequent and widespread threats to public safety and social development. Humanity's ability to harness and control fire is a key hallmark of civilization and progress. The history of humanity's use of fire and its struggle against it go hand in hand. While utilizing fire, people have continuously studied the patterns of fire occurrence and minimized the harm it causes to humans.

[0003] Fire extinguisher boxes are the most basic fire-fighting equipment and are often used in today's buildings. The main function of fire extinguishers is to place fire extinguishers and fire hydrants for emergency fire fighting in case of fire. This requires that fire extinguishers must be usable in emergency situations. The most common fire extinguishers are placed in fire extinguishers. As an essential tool for fire fighting, it is necessary to ensure that the fire extinguishers are in the normal range of use. Fire extinguishers generally store dry powder inside. Under normal circumstances, the weight of the fire extinguisher is fixed. After use, the weight will decrease. As fire-fighting supplies, it is necessary to ensure that fire-fighting supplies are available at any time. This requires that fire extinguishers be replaced in time after use.

[0004] Existing fire extinguisher boxes rely on manual inspections to check the weight of fire extinguishers. Fire extinguishers typically contain dry powder, and their weight is fixed under normal circumstances. However, after use or when stored for a long time, the weight of the extinguisher decreases. Firefighting supplies must be readily available, requiring fire extinguishers to be promptly replaced after use. Manual inspections are prone to missed inspections or incorrect inspections. Fire extinguishers may not be replaced promptly after use and may be placed back into the fire extinguisher box. Failures may only be discovered during the next use or during maintenance, potentially delaying firefighting and disaster relief efforts.

[0005] CN218165832U discloses an intelligent fire extinguisher box based on the Internet of Things. The fire extinguisher box requires an external power supply and its implementation requires the cooperation of multiple sensors.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0046] like Figures 1 to 17 As shown, the multifunctional fire extinguisher box of the present invention includes a box body 1 and a detection system 2. The detection system 2 can determine whether the weight of the fire extinguisher 3 has reached a minimum value. When the minimum value is reached, an alarm mechanism 4 in the detection system 2 will sound an alarm, reminding the staff to take timely action to avoid unnecessary trouble later.

[0047] The box body 1 is provided with a door 5, which is hinged to the box body 1. The door 5 is provided with a handle 6, and the box body 1 is provided with a ventilation hole 7. A layer of plate 8 is provided inside the box body 1, which divides the interior of the box body 1 into a first space 9 and a second space 10. The fire extinguisher 3 is located in the first space 9.

[0048] The detection system 2 is used to determine whether the weight of the fire extinguisher 3 has been reduced. The detection system 2 is located in the second space 10, and the upper end of the detection system 2 passes through the layer 8 and contacts the lower end of the fire extinguisher 3. The fire extinguisher 3 is kept on the detection system 2 to check whether the weight of the fire extinguisher 3 is within the acceptable range at any time.

[0049] The detection system 2 consists of a trigger mechanism 11 and an alarm mechanism 4 connected to the trigger mechanism 11. When the trigger mechanism 11 detects that the weight of the fire extinguisher 3 has decreased, the first spring 12 pushes the first hinge 13 and the second hinge 14, maintaining their upward push on the fire extinguisher 3. At the same time, the blocking rod 15 on the second hinge 14 passes over the blocking plate 16, freeing the elastic member 17 in the alarm mechanism 4 from external resistance. This releases the stored energy, driving the rotating shaft 18 to rotate, causing the protruding teeth 20 on the fixed plate 19 to continuously strike the alarm unit 21, causing it to emit a sound, alerting staff to promptly handle the situation.

[0050] The trigger mechanism 11 includes a support member 22 , a first retaining seat 23 located at the lower end of the support member 22 , a second retaining seat 24 cooperating with the first retaining seat 23 , and a movable assembly 27 disposed between the first movable chamber 25 and the second movable chamber 26 .

[0051] The support member 22 comprises a support portion 28 and a movable column 29. A placement slot 30 for the fire extinguisher 3 is provided in the middle of the support portion 28. The lower end of the movable column 29 is provided with an arcuate opening 31. The arcuate opening 31 has an angle greater than 180°, facilitating the rotation of a first hinged joint 32 therein. Furthermore, a first edge 33 of the arcuate opening 31 limits the rotation angle of the first hinged joint 32.

[0052] A through hole 34 for the support portion 28 to slide is provided on the box door 5. When the fire extinguisher 3 is placed in the placement groove 30 in the support portion 28, the support portion 28 is pushed downward by the gravity of the fire extinguisher 3, causing it to slide in the through hole 34.

[0053] The first retaining seat 23 is provided with a first slideway 35 that cooperates with the movable column 29, and a first movable chamber 25 is also provided in the center of the first retaining seat 23. The second retaining seat 24 is provided with a second slideway 36 that cooperates with the first slideway 35, and a second movable chamber 26 is also provided in the center of the second retaining seat 24. After the first retaining seat 23 and the second retaining seat 24 are mounted together, the first slideway 35 and the second slideway 36 form a slideway with a circular cross-section, facilitating the upward and downward sliding of the movable column 29 under load. The first movable chamber 25 and the second movable chamber 26 cooperate to form a movable chamber in which the movable assembly 27 moves, thereby maintaining the position of the movable assembly 27.

[0054] The movable assembly 27 is held bent by pressure from the fire extinguisher 3. This bending creates an angle between the first hinge 13 and the second hinge 14, which is less than 180°. When the weight of the fire extinguisher 3 decreases, the movable assembly 27 exerts a counterforce force, pushing the fire extinguisher 3 upward. Because the lower end of the second hinge 14 remains stationary, the first pusher 37 pushes the first and second hinges 13, 14, effectively keeping the first hinge 13 from pushing the support member 22 upward.

[0055] The movable component 27 is provided with a first spring 12, a first pushing block 37, a first hinge 13, a second hinge 14, a second pushing block 38 and a second spring 39. The first hinge 13 is located at the upper end of the second hinge 14, the first spring 12 is in contact with the first pushing block 37, the first pushing block 37 is located at one end of the first hinge 13 and the second hinge 14, the second pushing block 38 is located at the other end of the first hinge 13 and the second hinge 14, and the second spring 39 is in contact with the second pushing block 38.

[0056] A fixing groove 40 is formed on the second pushing block 38 . A ball 41 is disposed in the fixing groove 40 . The ball 41 is used to cooperate with the first hinge 13 and the second hinge 14 .

[0057] The first hinged member 13 comprises a first hinged head 32, a first connecting portion 42, and a first hinged end 43. The first connecting portion 42 is provided with an inwardly recessed first arcuate slot 44. The first hinged head 32 is located within the arcuate slot 31. The first hinged end 43 is provided with an arcuate hinge opening 45. The first arcuate slot 44 is configured to engage with the first edge 33 to limit the rotational angle of the first hinged member 13. A second edge 75 is provided at the lower end of the first hinged member 13, located at the hinge opening 45.

[0058] The second hinge member 14 comprises a second hinge end 46, a second connecting portion 47, and a second hinge joint 48. The second hinge end 46 is hingedly coupled to the hinge joint 45. A second, inwardly recessed arcuate groove 49 is provided at the junction of the second hinge end 46 and the second connecting portion 47, and at the junction of the second connecting portion 47 and the second hinge joint 48. The second arcuate groove 49 at the upper end of the second hinge member 14 is configured to cooperate with the second edge 75 to limit the rotation angle of the first hinge member 13.

[0059] A blocking rod 15 for limiting the position of the blocking piece 16 is provided on the second hinge end 46 .

[0060] The first movable chamber 25 and the second movable chamber 26 are both provided with a first half groove 50, a second half groove 51, a third half groove 52, a fourth half groove 53 and a fifth half groove 54, the first spring 12 is located in the first half groove 50, the first push block 37 is located in the second half groove 51, the first hinge 13 and the second hinge 14 are located in the third half groove 52, the second push block 38 is located in the fourth half groove 53, and the second spring 39 is located in the fifth half groove 54.

[0061] When the first retaining seat 23 and the second retaining seat 24 are installed together, the first half groove 50, the second half groove 51, the third half groove 52, the fourth half groove 53 and the fifth half groove 54 are merged together, and the various components of the movable assembly 27 can move therein.

[0062] At the same time, the third half groove 52 has a first limit opening 55 and a second limit opening 56. The first limit opening 55 is used to keep the first hinge 32 on the first hinge 13 rotating therein, and the second limit opening 56 is used to keep the second hinge 48 on the second hinge 14 rotating therein.

[0063] The second retaining seat 24 is provided with a strip groove 57 for the movement of the blocking rod 15. The strip groove 57 is arc-shaped and is located in the third half groove 52. Since the lower end of the second hinged member 14 rotates around the second limiting opening 56, the blocking rod 15 can slide in an arc shape therein, thereby facilitating the blocking piece 16 to pass over, so that the blocking piece 16 is no longer restricted by the blocking rod 15.

[0064] The deformation force of the blocking piece 16 is greater than the blocking force of the blocking rod 15, so that the blocking piece 16 does not deform. When the blocking rod 15 passes over the blocking piece 16, it can drive the blocking piece 16 to rotate, that is, drive the rotation shaft 18 to rotate. As a result, the blocking rod 15 passes over the blocking piece 16, so that the blocking piece 16 is no longer restricted by the blocking rod 15. At this time, the rotation shaft 18 can be pushed in the opposite direction by the elastic force of the elastic member 17.

[0065] The alarm mechanism 4 comprises a fixed seat 58, a fixed disk 19, a rotating shaft 18, a positioning post 59, a trigger disk 60, an alarm member 61, and an elastic member 17. The fixed seat 58 is mounted on the second retaining seat 24, the fixed disk 19 is mounted in the middle of the fixed seat 58, and the rotating shaft 18 is positioned between the fixed seat 58 and the fixed disk 19. The elastic member 17 is mounted on the fixed disk 19, with one end of the elastic member 17 connected to the fixed disk 19 and the other end connected to the rotating shaft 18. The fixed disk 19 does not rotate with the rotating shaft 18 but is fixed in the fixed seat 58.

[0066] A limiting seat 62 is provided on the second retaining seat 24 for mounting the fixing seat 58. The limiting seat 62 has a limiting opening 63. A partition 64 is provided in the limiting opening 63. The partition 64 has a vertical slot 65 for the rotation shaft 18 to pass through. A rotation area 66 for the blocking piece 16 to rotate is formed between the partition 64 and the second retaining seat 24.

[0067] One end of the rotating shaft 18 is provided with a locking groove 67, which requires the unlocking member 68 to cooperate with the rotating shaft 18 to rotate and store the energy of the elastic member 17. One end of the unlocking member 68 is provided with a locking protrusion 69 that cooperates with the locking groove 67.

[0068] A fixing plate 70 is provided on the fixing seat 58 . A first through hole 34 is provided on the fixing plate 70 , through which the unlocking member 68 passes. A second through hole 74 is provided on the box body 1 , through which the unlocking member 68 passes.

[0069] When the rotating shaft 18 rotates, the elastic member 17 keeps the end connected to the rotating shaft 18 rotating with it, storing energy. This energy is then released when the rotating shaft 18 rotates in the opposite direction. Specifically, when the middle end of the elastic member 17 is tightened by the rotating shaft 18, the energy is stored. The blocking piece 16 is then restrained by the blocking rod 15, preventing the rotating shaft 18 from rotating in the opposite direction. The elastic force of the elastic member 17 is less than the blocking force of the blocking rod 15.

[0070] The positioning column 59 is installed inside the fixed seat 58, the alarm component 61 is installed on the positioning column 59, and the trigger disk 60 is installed on the rotating shaft 18. As the rotating shaft 18 rotates together, the alarm component 61 contacts and connects with the trigger disk 60. A baffle 16 is provided on the rotating shaft 18, and a blocking rod 15 for limiting the position of the baffle 16 is provided in the movable component 27.

[0071] like Figure 17 As shown, the first hinge 13 and the second hinge 14 are now bent at their maximum angle, and the first spring 12 is compressed to its maximum value, while the second spring 39 is in its natural state. Furthermore, the elastic force of the first spring 12 is greater than the elastic force of the second spring 39, which facilitates the first spring 12 pushing the first hinge 13 and the second hinge 14 to rotate, thereby pushing the support member 22 and the second push block 38 to move, keeping the second spring 39 compressed.

[0072] The trigger plate 60 is provided with a plurality of protruding teeth 20, with a stopper 71 formed between the protruding teeth 20. The alarm member 61 comprises an energy storage portion 72, an alarm portion 21, and a positioning portion 73. The energy storage portion 72 is spirally sleeved onto the positioning post 59, the positioning portion 73 abuts against the inner wall of the fixing seat 58, and the alarm portion 21 is positioned within the stopper 71.

[0073] When the trigger plate 60 is driven to rotate by the rotating shaft 18, it can push the alarm part 21 to produce a knocking sound to alert the staff.

[0074] Since one end of the alarm member 61 is received at the inner wall limit position of the fixing seat 58 , the alarm portion 21 will be subjected to a rebound force after being subjected to force, and the alarm portion 21 will knock against the protruding tooth 20 to produce a sound.

[0075] When the fire extinguisher 3 is taken out for use, the elastic member 17 will release energy. At this time, it is only necessary to use the unlocking member 68 to reversely rotate the rotating shaft 18 to allow the elastic member 17 to store energy again and continue to use it next time. It not only does not require external power support, but can also be used multiple times, saving costs, does not require a special usage environment, and has high adaptability.

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
