Description

Technical Field

[0001] The utility model relates to the technical field of fire escape products, in particular to a damage-resistant firefighting air cushion. Background Art

[0002] Firefighting air cushion is a special equipment used for rescue and firefighting. It is a device that uses high-pressure gas or liquid to inflate, and has the characteristics of being shaped like a cushion. Firefighting air cushions are usually made of wear-resistant and flame-retardant materials, and have the characteristics of being resistant to pressure, heat and corrosion. Firefighting air cushions play a role in slowing down the fall or buffering during the rescue process. They can be used to rescue trapped people from high places such as high-rise buildings and bridges, or to rescue trapped people at the scene of a fire. Firefighting air cushions can effectively reduce the impact of falling and protect the rescued from secondary injuries.

[0003] For example, the utility model with application number CN202223368680.1 discloses a fire escape air cushion. The utility model places an air cushion cabin with a counterweight fixed to the bottom in a safe position, and inflates the interior of the air cushion cabin so that the air column at the upper end of the air cushion cabin is fully extended, thereby preventing the escapee from rolling down the lower side of the air cushion cabin. At the same time, the escapee falls on the upper side of the air cushion cabin, and part of the gas inside the air cushion cabin is discharged from the air valve under the action of the impact force, thereby alleviating the impact force on the escapee and the air cushion cabin. However, when the air cushion cabin rubs against objects with sharp materials during movement, scratches or even damage will appear on the bottom surface, affecting the rescue work.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-damage fire-fighting air cushion is proposed. Utility Model Content

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, a damage-resistant fire-fighting air cushion comprises a support seat 1 and a screw nut 4, wherein a trapezoidal screw 2 is rotatably connected to the rear end of the support seat 1, and the other end of the trapezoidal screw 2 passes through the front end of the support seat 1 and is connected to a hand crank 3, the screw nut 4 is arranged on the outside of the trapezoidal screw 2, and connecting blocks 5 are arranged on both sides of the screw nut 4, the middle part of the connecting block 5 is connected to a scissor rod 6 through a rotating shaft, and the other end of the scissor rod 6 is connected to a side plate 7 through a rotating shaft, the side surface of the support seat 1 is a "return" type structure, the trapezoidal screw 2 and the side plate 7 are parallel to each other, and the surface of the side plate 7 is provided with a slide groove 8, and a sliding pin 10 is connected in the slide groove 8, the bottom of the sliding pin 10 is rotatably connected to a scissor rod 29, and the other end of the scissor rod 29 is rotatably connected to the support seat 1, the middle part of the scissor rod 16 is rotatably connected to the scissor rod 29 through a rotating shaft, and two scissor rods 16 and two scissor rods 29 are each provided, a base frame 11 is fixed on the right side of the side panel 7 on the right, and a pallet 12 is fixed on the top of the base frame 11, a base frame 2 13 is fixed on the left side of the side panel 7 on the left, and a pallet 2 14 is fixed on the top of the base frame 2 13, and an air cushion cabin 16 is installed on the top of the pallet 12.

[0023] The specific operation is as follows: the pallet 12, the support seat 1 and the pallet 2 14 can be used to support the air cushion capsule 16 in a full state after being spliced. The pallet 12, the support seat 1 and the pallet 2 14 replace the air cushion capsule 16 to directly contact the ground, so as to avoid the air cushion capsule 16 being damaged due to friction with objects with sharp materials on the ground when the air cushion capsule 16 is pulled.

[0024] like Figure 1 As shown, pallet 12 and pallet 2 14 are parallel to each other, pallet 12 and pallet 2 14 have the same size, the top surface of pallet 2 14 is provided with anti-slip grooves 15, and the anti-slip grooves 15 are equidistantly distributed along the top surface of pallet 2 14, the surface of the air cushion cabin 16 is pasted with reflective strips 17, and the bottoms of base frame 1 11 and base frame 2 13 are both equipped with brake casters 18.

[0025] The specific operation is as follows: the setting of the caster 18 with brakes facilitates the overall movement of the air cushion capsule 16; a reflective strip 17 with a rectangular structure design is provided on the surface of the air cushion capsule 16; by marking the four sides of the air cushion capsule 16, it can be easily found by escapees, greatly increasing the efficiency of rescue; the anti-slip pattern 15 is used to increase the static friction between the air cushion capsule 16 and the second pallet 14, preventing the air cushion capsule 16 from slipping on the second pallet 14.

[0026] In summary, when the anti-breakage fire-fighting air cushion is used, first, the trapezoidal screw rod 2 has a certain self-locking property, and the hand crank 3 is used to provide a rotational force for the trapezoidal screw rod 2, so that the screw nut 4 drives the connecting blocks 5 on the left and right sides to move along the outside of the trapezoidal screw rod 2. During the displacement process, the sliding pin 10 slides in the sliding groove 8 on the surface of the side plate 7, so that the distance between the support plate 12 and the support plate 2 14 increases with the increase of the crossing angle between the scissor rod 1 6 and the scissor rod 2 9 until it is as shown in FIG. Figure 1 and Figure 2 As shown;

[0027] Since the area of ​​the first support plate 12, the support seat 1 and the second support plate 14 after being spliced ​​is larger than the air cushion capsule 16 in a full state, the air cushion capsule 16 can be prevented from slipping on the second support plate 14 when being used for lifesaving by unfolding the end of the air cushion capsule 16 away from the first support plate 12 and laying it on the support seat 1 and the second support plate 14, and then increasing the static friction with the help of the anti-slip groove 15;

[0028] At the same time, the air cushion capsule 16 is directly in contact with the ground through the support plate 12, the support seat 1 and the support plate 2 14, and the casters 18 with brakes at the bottom of the bottom frame 11 and the bottom frame 2 13 provide mobility, which avoids scratches or even damage on the surface of the air cushion capsule 16 due to friction with sharp objects on the ground when the air cushion capsule 16 is pulled, thereby ensuring the structural integrity of the air cushion capsule 16 and the safety of use;

[0029] When used at night, the reflective strip 17 warns the surrounding boundaries of the air cushion cabin 16, which can prevent the escapee from jumping out of the air cushion cabin 16, ensuring safety and rescue speed. At the end of the rescue, the gas in the air cushion cabin 16 is first released, and then the hand crank 3 is turned to reduce the distance between the support plate 12 and the support plate 2 14 as the crossing angle between the scissor rod 1 6 and the scissor rod 2 9 decreases, until the rescue is completed. Figure 3 As shown, the effect of stacking and storing the pallet 12 and the pallet 2 14 is achieved, which is convenient for carrying.

[0030] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
