[0033] like Figures 1 to 5 As shown, the present invention provides a fire-fighting device with a simple structure and low overall cost. It is suitable for large-scale production and can be used in crowded areas such as production units, high-rise residential buildings, shopping malls, stations, and hotels. The fire-fighting device includes a fire-extinguishing device, which includes a fixed box, a fire extinguisher ejection mechanism 1, and a fire extinguisher 2. The fixed box is fixed to the wall by screws and has an opening. The fire extinguisher ejection mechanism 1 includes a driving member 11, a first gear 12, a first telescopic bracket 13, a connecting member 14, a second telescopic bracket 15, and a fixing assembly 16. The driving member 11 is fixed in the fixed box and is arranged away from the opening. In this embodiment, the driving member 11 is a motor, which is fixed to the fixed box by screws. The output end of the driving member 11 is transmission-connected to the first gear 12 for driving the first gear 12 to rotate. The first telescopic bracket 13 includes a first connecting rod 131, and a second gear 132 and a third gear 133 are respectively fixed at both ends of the first connecting rod 131. The second gear 132 is rotationally connected to the fixed box and meshes with the first gear 12. The third gear 133 is rotationally connected to the connecting member 14. In this embodiment, the first connecting rod 131, the second gear 132, and the third gear 133 are an integrated structure, which has a good transmission effect and is convenient for installation with the fixed box and the connecting member 14. In other embodiments, the second gear 132 and the third gear 133 are both detachably connected to the first connecting rod 131. The second telescopic bracket 15 includes a second connecting rod 151, one end of which is fixed with a fourth gear 152, which is rotatably connected to the connecting member 14 and meshes with the third gear 133; the other end of the second connecting rod 151 is rotatably connected to the fixing assembly 16; and the fire extinguisher 2 is detachably connected to the fixing assembly 16. In this embodiment, the second connecting rod 151 and the fourth gear 152 are an integrated structure, which has a good transmission effect and is convenient for installation with the connecting member 14. In other embodiments, the second gear 132 and the second connecting rod 151 are detachably connected. When a fire occurs, the driving member 11 controls the first gear 12 to rotate counterclockwise, which in turn causes the second gear 132 to rotate clockwise, and drives the first connecting rod 131 to rotate clockwise, which in turn causes the third gear 133 to rotate clockwise. At the same time, the fourth gear 152 rotates counterclockwise, which in turn drives the second connecting rod 151 to rotate counterclockwise, thereby automatically ejecting the fire extinguisher 2 and moving the fire extinguisher 2 to the opening of the fixed box, making the fire extinguisher 2 visible and easy to take. The operator then only needs to remove the fire extinguisher 2 from the fixed assembly 16 to extinguish the fire, which can improve fire extinguishing efficiency.

[0034] Optionally, in this embodiment, the first telescopic bracket 13 further includes a third connecting rod 134, one end of which is rotatably connected to the fixed box and the other end of which is rotatably connected to the connecting member 14. The third connecting rod 134 is parallel to the first connecting rod 131, thereby maintaining the motion trajectory of the connecting member 14 while ensuring a smoother transmission of the first telescopic bracket 13. In this embodiment, the second telescopic bracket 15 further includes a fourth connecting rod 153, one end of which is rotatably connected to the connecting member 14 and the other end of which is rotatably connected to the fixed assembly 16. The fourth connecting rod 153 is parallel to the second connecting rod 151, thereby maintaining the motion trajectory of the fixed assembly 16 while ensuring a smoother transmission of the second telescopic bracket 15.

[0035] Optionally, the fire extinguisher ejection mechanism 1 further includes a first elastic member 17 and a second elastic member 18. One end of the first elastic member 17 is rotatably connected to the first connecting rod 131, and the other end is rotatably connected to the third connecting rod 134 or the connecting member 14. The second elastic member 18 has one end rotatably connected to the second connecting rod 151, and the other end is rotatably connected to the fourth connecting rod 153 or the connecting member 14. The first and second elastic members 17, 18 act as buffers during the process of extending or retracting the fire extinguisher 2 by the fire extinguisher ejection mechanism 1. Once the fire is extinguished or completely dealt with, the first gear 12 is driven clockwise by the driver 11. With the assistance of the first and second elastic members 17, 18, the first and second telescopic brackets 13, 15 retract, returning the fire extinguisher 2 to its stowed position. Optionally, in this embodiment, both the first and second elastic members 17, 18 are gas springs. During operation, gas springs open and close relatively slowly, reducing shock and vibration. In other embodiments, both the first and second elastic members 17, 18 are compression springs or tension springs.

[0036] Alternatively, as Figure 4 As shown, two first elastic members 17 and two second elastic members 18 are provided. The two first elastic members 17 are respectively arranged on opposite sides of the first connecting rod 131 and are arranged in parallel. The two second elastic members 18 are respectively arranged on opposite sides of the second connecting rod 151 and are arranged in parallel. This arrangement ensures that the forces acting on the first telescopic bracket 13 and the second telescopic bracket 15 are balanced, and the stability of the structure is guaranteed.

[0037] Optionally, the fixed box includes a housing and a first support base 3 fixed within the housing, and the fixed assembly 16 includes a second support base 161. The first support base 3, the second support base 161, and the connector 14 are each provided with a receiving cavity. The two ends of the first connecting rod 131 are respectively disposed within the receiving cavity of the first support base 3 and the receiving cavity of the connector 14, and are respectively in contact with the inner walls of the corresponding receiving cavity. The two ends of the second connecting rod 151 are respectively disposed within the receiving cavity of the connector 14 and the receiving cavity of the second support base 161, and are respectively in contact with the inner walls of the corresponding receiving cavity. By making the connecting rods in contact with the inner walls of the receiving cavity, the walls of the receiving cavity serve as guides during the extension or retraction of the first telescopic bracket 13 and the second telescopic bracket 15. This configuration can also save space occupied by the fire extinguisher ejection mechanism 1.

[0038] Specifically, the connecting member 14 includes two parallel, spaced-apart fixing plates 141 and four connecting shafts. The four connecting shafts connect the two fixing plates 141. The four connecting shafts are respectively a first connecting shaft, a second connecting shaft, a third connecting shaft, and a fourth connecting shaft. The first connecting shaft is rotationally connected to the third gear 133, the second connecting shaft is rotationally connected to the fourth gear 152, the third connecting shaft is rotationally connected to the third connecting rod 134, and the fourth connecting shaft is rotationally connected to the fourth connecting rod 153. In this embodiment, one end of the first elastic member 17 is ball-jointed to the first connecting rod 131, and the other end is ball-jointed to the third connecting shaft. The second elastic member 18 is ball-jointed to the second connecting rod 151, and the other end is ball-jointed to the fourth connecting shaft, allowing for more flexible rotation of the elastic member relative to the telescopic bracket.

[0039] Optionally, the fixing assembly 16 includes a second support base 161 and a clamping member 162. The other end of the second connecting rod 151 is rotatably connected to the second support base 161. The clamping member 162 is connected to the second support base 161 and is clamped to the fire extinguisher 2. Clamping the fire extinguisher 2 to the clamping member 162 makes it convenient for the operator to take the fire extinguisher 2, saving time. Specifically, the clamping member 162 can be detachably connected to the second support base 161 through a fastener, and the clamping member 162 can also be welded to the second support base 161. In addition, in this embodiment, if Figure 5 As shown, the clamping member 162 includes a connecting portion 1621, a clamping portion 1622, and a base 1623. The connecting portion 1621 is connected to the second support base 161. Two clamping portions 1622 are provided on both sides of the connecting portion 1621 for clamping the fire extinguisher 2. The base 1623 is provided at the bottom end of the connecting portion 1621 for supporting the fire extinguisher 2 to prevent the fire extinguisher 2 from falling due to insufficient clamping force. Specifically, the clamping portion 1622 is provided with a notch 1624, which facilitates the operator to grasp the fire extinguisher 2 through the notch 1624 when removing the fire extinguisher 2.

[0040] Optionally, the fire extinguishing device further includes an alarm sound and light indicator, which is fixed to the fire extinguisher ejection mechanism 1 or the fire extinguisher 2 and is configured to emit sound and light. When a fire occurs, a large amount of thick smoke is generated, which obscures the vision of personnel on site, making it difficult for them to quickly locate the fire extinguisher 2. The alarm sound and light indicator emits a sound of "fire extinguisher, fire extinguisher..." and flashes a light, guiding personnel on site to quickly locate the fire extinguisher 2, enabling fire extinguishing to be carried out at the optimal initial stage, thereby reducing casualties and property losses.

[0041] Optionally, the firefighting equipment further includes a monitoring device for monitoring the fire situation. Optionally, if multiple fire extinguishing devices are provided, the firefighting equipment further includes multiple positioning members, each corresponding to one of the multiple fire extinguishing devices and each communicatively connected to the monitoring device. The monitoring device uses the positioning members to determine the position of the fire extinguishing devices. The monitoring device is communicatively connected to the driver 11 to control the operation of the driver 11. The monitoring device is also communicatively connected to the alarm sound and light indicator to control the operation of the alarm sound and light indicator. Specifically, the positioning members are provided on the fixed box, the fire extinguisher ejection mechanism 1, or the fire extinguisher 2.

[0042] When the monitoring device detects a fire, it automatically determines the location of the fire. Since the fire extinguishing device is provided with a positioning member, the monitoring device can determine the position of the fire extinguishing device closest to the fire point through the positioning member, and automatically sort it, and trigger the driving member 11 of the fire extinguishing device at the corresponding position to move, so as to pop out the fire extinguisher 2, and at the same time trigger the alarm sound and light indicator of the fire extinguishing device at the corresponding position to emit flashing lights and sounds, reminding on-site personnel to find the location of the fire extinguisher 2 in time, quickly take the fire extinguisher 2 to organize fire extinguishing, and reduce personnel and property losses.

[0043] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
