[0024] Reference Figures 1 to 4 , an embodiment provided by the utility model:

[0025] A cabinet-type fire extinguishing device includes a cabinet, a fire extinguisher 1 placed in the cabinet, and a support plate 2 supported below the fire extinguisher 1. The cabinet includes a base plate 3 at the bottom and a back plate 4 at the back:

[0026] Pulleys 5 arranged along the front-to-back direction are provided below the support plate 2, and guide rails 6 matching the pulleys 5 are provided above the bottom plate 3, and the pulleys 5 are rollingly connected to the guide rails 6; a vertically through-going cavity 7 is provided in the middle of the support plate 2, and a movable flap 8 is embedded in the cavity 7, and the movable flap 8 is rotatably connected to the cavity 7 along the front-to-back direction; the front end of the movable flap 8 is rotatably connected to a support wheel 9, and the rear end of the movable flap 8 is provided with a hand-held handle 10; a fixing mechanism for clamping the fire extinguisher 1 is provided between the back plate 4 and the fire extinguisher 1.

[0027] The cabinet is placed on the ground and has a rectangular structure. There is an installation space inside the cabinet for placing the fire extinguisher 1. There are several supporting legs under the cabinet for supporting the cabinet. The bottom plate 3 is located at the bottom of the cabinet and is used to install the support plate 2. The back plate 4 is located on the back of the cabinet and is used to install the fixing mechanism. The support plate 2 is horizontally arranged and installed above the bottom plate 3 to support the fire extinguisher 1. The pulley 5 is installed below the support plate 2, and several pulleys 5 are arranged in the front-to-back direction. The guide rail 6 is installed above the bottom plate 3, matching the size and position of the pulley 5. The guide rail 6 is arranged in the front-to-back direction, and the pulley 5 is installed in the guide rail 6 and is rollingly connected to the guide rail 6, so that the support plate 2 can be slid out and pushed in along the front-to-back direction. The cavity 7 is located in the middle of the support plate 2, opened downward from the surface of the support plate 2, and is vertically through. The movable flap 8 matches the shape and position of the cavity 7, and is embedded in the cavity 7. The movable flap 8 is flush with the surface of the support plate 2. The movable flap 8 is provided with protruding rotating shafts on the left and right sides, and the inner side of the cavity 7 is provided with an axial hole corresponding to the rotating shaft. The rotating shaft is rotatably connected to the axial hole, so that the movable flap 8 is rotatably connected to the cavity 7, so that the movable flap 8 can be rotated to open and close in the front-to-back direction. The support wheel 9 is located at the front end of the movable flap 8 and is rotatably connected to the movable flap 8. The distance from the rotating shaft to the outside of the support wheel 9 can be equal to the distance from the rotating shaft to the ground, ensuring that after the movable flap 8 is opened, the support wheel 9 is in contact with the ground. A through avoidance groove can be provided on the front side of the base plate 3. The front side of the avoidance groove is open and has a U-shaped structure, so that when the movable flap 8 is unfolded, the support wheel 9 will not interfere with or collide with the base plate 3. The hand-held handle 10 is located at the rear end of the movable flap 8 and has a cylindrical structure. It is arranged in the left-right direction. The hand-held handle 10 is flush with the surface of the support plate 2 to avoid blocking the movement of the fire extinguisher 1.

[0028] When the movable flap 8 rotates forward relative to the cavity 7, the movable flap 8 moves upward away from the cavity 7, and the angle between the movable flap 8 and the support plate 2 increases, until the movable flap 8 rotates forward 90 degrees, the movable flap 8 is perpendicular to the support plate 2, the support wheel 9 is in contact with the ground, and the movable flap 8 is in the deployed state. The support plate 2 is pulled out or pushed in by pushing and pulling the handheld handle 10. Conversely, when the movable flap 8 rotates backward relative to the cavity 7, the movable flap 8 moves downward toward the cavity 7, and the angle between the movable flap 8 and the support plate 2 decreases, until the movable flap 8 rotates backward 90 degrees, the movable flap 8 is flush with the support plate 2, the movable flap 8 is embedded in the cavity 7, the support wheel 9 is stored in the support plate 2, and the movable flap 8 is in the stored state. The fixing mechanism is installed between the back plate 4 and the fire extinguisher 1 and may include a clamping hand 13 for clamping the fire extinguisher 1 and a driving assembly installed on the back plate 4 . The clamping hand 13 clamps the fire extinguisher 1 under the drive of the driving assembly.

[0029] Working principle:

[0030] 1) In the initial state, the support plate 2 is located inside the cabinet, and the movable flap 8 is embedded in the cavity 7.

[0031] 2) To install the fire extinguisher 1, the operator grasps the hand-held handle 10 and pulls the movable flap 8 upward. The movable flap 8 is then rotated forward 90 degrees until the movable flap 8 is perpendicular to the support plate 2 and the support wheels 9 are in contact with the ground. The movable flap 8 is in the deployed state. By pulling the hand-held handle 10 forward, the support plate 2 is pulled out and the fire extinguisher 1 is placed on top of the support plate 2.

[0032] 3) When the fire extinguisher 1 needs to be stored, the handheld handle 10 is pushed backward to push the support plate 2 inward, and the fire extinguisher 1 is stored inside the cabinet. The staff pushes the movable flap 8 downward and folds it. The movable flap 8 rotates 90 degrees backward until it is flush with the support plate 2. The movable flap 8 is embedded in the cavity 7, and the support wheel 9 is stored in the support plate 2. The movable flap 8 is in the stored state, and the fire extinguisher 1 is then clamped and fixed using the fixing mechanism.

[0033] The present invention provides a movable flap 8. When the placement plate needs to be pulled out, the staff member grasps the handheld handle 10 and pulls the movable flap 8 upward to open it. The support wheel 9 contacts the ground, and the movable flap 8 is in an extended state. The pulley 5 and the guide rail 6 are in rolling connection, making the push-pull operation more labor-saving. After use, the movable flap 8 is pushed downward to fold it. The movable flap 8 is embedded in the cavity 7, and the support wheel 9 is stored in the support plate 2. The movable flap 8 is in a stored state, realizing the rotating storage function. At the same time, after the placement plate is pulled out, the support wheel 9 contacts the ground to provide support for the placement plate, preventing the placement plate from being suspended in the air and easily deformed by downward pressure.

[0034] In this embodiment, preferably, a baffle 11 extending upward is provided on the surface of the support plate 2. The front side of the baffle 11 is in an arc-shaped structure and abuts against the rear side of the fire extinguisher 1. The upper side of the baffle 11 corresponds to the position of the fixing mechanism.

[0035] The baffle 11 extends upward from the surface of the support plate 2 and is arranged near the rear side of the support plate 2. The front side of the baffle 11 is an arc-shaped structure, which matches the external contour of the fire extinguisher 1. The upper part of the baffle 11 corresponds to the position of the fixing mechanism. It can be understood that the upper part of the baffle 11 corresponds to the clamping area of ​​the fixing mechanism. When the fire extinguisher 1 needs to be installed, the fire extinguisher 1 is placed on the surface of the support plate 2, and the fire extinguisher 1 is pushed backward until the rear side of the fire extinguisher 1 abuts against the front side of the baffle 11. The baffle 11 acts as a limiter in the rear direction of the fire extinguisher 1 to prevent the fire extinguisher 1 from falling backward, while ensuring that the fire extinguisher 1 is located in the clamping area of ​​the fixing mechanism.

[0036] In this embodiment, preferably, a surface of the support plate 2 is provided with fixing blocks 12 arranged along the front-to-back direction. The fixing blocks 12 are plugged into the support plate 2 and are correspondingly arranged on the left and right sides of the fire extinguisher 1 .

[0037] The fixing block 12 is a long straight strip structure, which is arranged along the front-to-back direction. The two fixing blocks 12 are symmetrically arranged about the front-to-back center line of the support plate 2, and are correspondingly arranged on the left and right sides of the fire extinguisher 1. The fixing block 12 is installed on the surface of the support plate 2 and is movably connected to the support plate 2. The fixing block 12 can be provided with a downwardly extending buckle at the bottom of the fixing block 12, and a card slot that matches the shape and position of the buckle is provided on the surface of the support plate 2. The card slot is arranged along the left-right direction, and the buckle and the card slot are detachably connected. By adjusting the installation position of the buckle, the distance between the two fixing blocks 12 is controlled, so as to adapt to fire extinguishers 1 of different sizes. The fixing block 12 plays a role in limiting the left and right directions of the fire extinguisher 1, thereby improving the installation stability of the fire extinguisher 1.

[0038] In this embodiment, as a preference, a travel block for limiting the rotation angle is provided below the support plate 2 , the travel block overlaps the movable flap 8 and corresponds to the rear end position of the movable flap 8 .

[0039] A travel block is installed below the support plate 2, corresponding to the rear end of the movable flap 8. The travel block extends toward the cavity 7, partially blocking the area below the cavity 7 and limiting the rotation angle of the rear end of the movable flap 8. To store the fire extinguisher 1, the operator pushes the movable flap 8 downward, causing it to rotate 90 degrees rearward. The travel block then overlaps the movable flap 8, preventing it from rotating further rearward, ensuring that it is flush with the support plate 2. The movable flap 8 is then embedded within the cavity 7, and the movable flap 8 is in the stored position.

[0040] In this embodiment, as a preference, a stop block for controlling the rotation stroke is provided below the movable flap 8 , the stop block abuts against the support plate 2 and corresponds to the front end position of the movable flap 8 .

[0041] The stop block is installed below the movable flap 8, corresponding to the front end of the movable flap 8. The stop block can be a right triangle structure, including two perpendicular right-angled surfaces, one of which is fixedly connected to the movable flap 8, and the other right-angled surface abuts the support plate 2, used to control the rotational travel of the front end of the movable flap 8. When the fire extinguisher 1 needs to be installed, the staff pulls the movable flap 8 upward and opens it. The movable flap 8 rotates forward 90 degrees, and the stop block abuts the support plate 2, preventing the movable flap 8 from further rotating forward, ensuring that the movable flap 8 is perpendicular to the support plate 2, the support wheel 9 is in contact with the ground, and the movable flap 8 is in the deployed state.

[0042] In this embodiment, preferably, the fixing structure includes a clamping hand 13 slidably connected to the back plate 4 along the left-right direction, one end of the clamping hand 13 is clamped with the fire extinguisher 1, and the other end of the clamping hand 13 is connected to the driving assembly.

[0043] The gripper 13 is slidably connected to the back plate 4, and the back plate 4 may be provided with a slide groove arranged in the left and right directions, and the gripper 13 is installed in the slide groove. There are two symmetrical grippers 13, which are respectively located on the left and right sides of the fire extinguisher 1, and the two grippers 13 can be close to or away from each other. One end of the gripper 13 is engaged with the fire extinguisher 1, and the other end of the gripper 13 is connected to the drive assembly. The drive assembly can be manual or electric, and the drive assembly and the gripper 13 are connected by a transmission component. Driven by the drive assembly, the two grippers 13 slide in the left and right directions, and the two approach each other until they abut against the left and right sides of the fire extinguisher 1, thereby achieving the clamping of the fire extinguisher 1.

[0044] In this embodiment, preferably, a rotatable and foldable V-shaped frame is provided at the end of the clamping hand 13 , and a clamping roller 14 is rotatably connected to the end of the V-shaped frame, and the clamping roller 14 abuts against the fire extinguisher 1 .

The end of the V-frame is rotatably connected to the clamping roller 14, and the clamping roller 14 is used to abut against the fire extinguisher 1. The V-frame has the function of being rotatable and foldable. When the V-frame is rotated and unfolded, the relative distance of the clamping roller 14 increases, and it can adapt to fire extinguishers 1 with larger sizes. When the V-frame is rotated and folded, the relative distance of the clamping roller 14 decreases, and it can adapt to fire extinguishers 1 with smaller sizes. Driven by the drive assembly, the two clamping hands 13 slide in the left and right directions, and the two V-frames approach each other until the clamping roller 14 abuts against the left and right sides of the fire extinguisher 1, thereby achieving the clamping of the fire extinguisher 1. By rotating and folding the V-frame, the relative distance of the clamping roller 14 can be adjusted, so as to adapt to fire extinguishers 1 of different sizes.

[0046] In this embodiment, preferably, the V-shaped frame includes two V-shaped butt-jointed rods 15 , one end of the two rods 15 is hinged to each other, the other ends of the two rods 15 are respectively connected to the clamping rollers 14 , and a return spring 16 is connected between the two rods 15 .

[0047] The two rods 15 are connected in a V-shape. One end of the two rods 15 is hinged to each other and can rotate relative to each other to achieve rotation, expansion and folding. The other ends of the two rods 15 are respectively connected to the clamping rollers 14. The rods 15 and the clamping rollers 14 correspond one to one, that is, each V-shaped frame includes two rods 15 and two clamping rollers 14. The two rods 15 are connected by a reset spring 16. Under the action of the spring force, the two rods 15 have an elastic expansion and contraction function. Driven by the drive assembly, the two clamping hands 13 slide in the left and right directions, and the two V-shaped frames approach each other until the clamping rollers 14 abut against the left and right sides of the fire extinguisher 1. Under the squeeze effect, the V-shaped frame rotates and expands, and the relative angle between the two rods 15 increases. The reset spring 16 is in a stretched state, thereby providing clamping force for the two rods 15, ensuring that the clamping rollers 14 always remain in close contact with the fire extinguisher 1 during the clamping process, and the V-shaped frame automatically adjusts to the appropriate rotation angle, thereby achieving the function of adaptive size adjustment of the fire extinguisher 1.

[0048] In this embodiment, preferably, the driving assembly includes a rotatably arranged driving plate 17, the outer edge of the driving plate 17 is provided with a centrally symmetrically arranged extension portion 18, the extension portion 18 is rotatably connected to a linkage plate 19, and the linkage plate 19 is rotatably connected to the clamping hand 13.

[0049] The driving plate 17 is rotatably arranged and may be mounted on the front side of the back plate 4.

One end of the linkage plate 19 is rotatably connected to the clamping hand 13, and the other end of the linkage plate 19 is rotatably connected to the extension 18. In addition, the clamping hand 13 is slidably connected to the back plate 4. It can be understood that the driving plate 17, the linkage plate 19, and the clamping hand 13 are transmission-connected, and the three constitute a crank slider transmission structure. In the initial state, the extension 18 of the driving plate 17, the linkage plate 19, and the clamping hand 13 are in the same straight line, the distance between the two clamping hands 13 is the largest, and the clamping hand 13 is in the open state. When the fire extinguisher 1 needs to be clamped, the driving plate 17 is controlled to rotate, the extension part 18 drives the linkage plate 19, and the linkage plate 19 drives the clamping hands 13, so that the two clamping hands 13 approach each other until the driving plate 17 rotates to a 90-degree angle, the distance between the two clamping hands 13 is minimized, and the clamping hands 13 are in a clamping state.

[0050] In this embodiment, as a preference, the back plate 4 is rotatably connected to a drive shaft, one end of the drive shaft is coaxially connected to the drive plate 17 , and a handheld turntable 20 is mounted on the other end of the drive shaft.

[0051] The drive shaft is rotatably connected to the back plate 4, extending through the back plate 4. A bearing may be installed between the drive shaft and the back plate 4.
