[0023] Example 1:

[0024] Please see Figures 1-4As shown, a new type of fire rescue support includes: a mounting frame 1, a fixed plate 2 fixedly installed at the bottom of the mounting frame 1, a movable plate 3 slidably installed at the bottom of the mounting frame 1, the fixed plate 2 and the movable plate 3 are arranged opposite to each other and anti-slip pads 4 are fixedly installed on the outer side walls of opposite ends, an adjustment component is provided at the top of the mounting frame 1, a mounting seat 5 is fixedly installed at the top of the mounting frame 1, a diagonal bracing mechanism is rotatably installed on the mounting seat 5, and a lifting component is provided at the top of the mounting frame 1;

[0025] The diagonal bracing mechanism includes a support plate 6 rotatably mounted on the top of the mounting base 5. The support plate 6 has an installation cavity inside. An extension plate 7 is slidably mounted on the inner side wall of the installation cavity. The top of the extension plate 7 passes through the installation cavity and extends outward. The top of the extension plate 7 is arc-shaped. The top of the mounting frame 1 is provided with a support component, and the support plate 6 is provided with a limiting component.

[0026] As can be seen from the above, the design of the diagonal bracing mechanism significantly improves the stability and safety of the fire rescue support. In actual use, the support plate 6 can rotate around the mounting base 5. After adjusting to a suitable angle, the extension plate 7 slides out from the mounting cavity of the support plate 6 to adjust the length of the diagonal bracing, making it easier for the extension plate 7 to contact the wall. The arc-shaped top design of the extension plate 7 allows it to better fit the support surface and expand the support area.

[0027] By adjusting the settings of the components, the movable plate 3 can be moved towards the fixed plate 2, so that the movable plate 3 and the fixed plate 2 cooperate to clamp and fix the windowsill, and the mounting bracket 1 is fixedly installed on the windowsill.

[0028] Specifically, regarding the aforementioned support components and limiting components, please refer to... Figure 2 and Figure 3 As shown, the support assembly includes a vertical plate 8 fixedly mounted on the top of the mounting frame 1. A threaded rod 9 is threaded through and connected to the vertical plate 8. A first rotating block and a support block 10 are fixedly mounted at the ends of the threaded rod 9, respectively. The support block 10 is located on the side close to the support plate 6, and the outer wall of the support block 10 on the side close to the support plate 6 is arc-shaped.

[0029] The limiting assembly includes two limiting rods 11 that pass through and are threaded onto the outer side wall of the support plate 6. The two limiting rods 11 are symmetrically arranged and a second rotating block is fixedly installed on the outer side wall of the opposite end. Limiting openings 12 that are adapted to the limiting rods 11 are opened on both sides of the outer side wall of the extension plate 7. The ends of the limiting rods 11 are inserted into the corresponding limiting openings 12.

[0030] As can be seen from the above, the vertical plate 8 in the support assembly is fixed to the top of the mounting frame 1, and the threaded rod 9 passes through the vertical plate 8 and is threadedly connected to it. By rotating the threaded rod 9, the position of the support block 10 can be adjusted so that it fits tightly against the support plate 6, providing additional support force to the support plate 6 and preventing it from shifting or shaking when under force. It should be noted that the threaded rod 9 is provided with two limiting blocks. When the limiting block near the support block 10 contacts the outer wall of the vertical plate 8, it limits the threaded rod 9 and the support block 10. After the support block 10 contacts the support plate 6, the support plate 6 and the mounting frame 1 are in a vertical state. By setting and using the limiting blocks, the support plate 6 is prevented from rotating in the direction of the vertical plate 8, thus ensuring the support effect of the support plate 6.

[0031] The limiting rod 11 in the limiting assembly is threaded onto the outer wall of the support plate 6. By rotating the limiting rod 11, its end is inserted into the limiting port 12 at the corresponding position of the extension plate 7, which can effectively limit the sliding of the extension plate 7, ensure that the extension plate 7 remains stably extended during use, and prevent it from retracting into the support plate 6 due to external force. This improves the stability of the entire bracket when lifting heavy objects, prevents the mounting bracket 1 from rotating around the edge of the windowsill, reduces the risk of overturning, and ensures the safe conduct of rescue operations.

[0032] Specifically, regarding the aforementioned adjustment components, please refer to... Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly includes an adjustment plate 13 set on the top of the movable plate 3, and a connecting block 14 fixedly set at the bottom of the adjustment plate 13. The bottoms of the two connecting blocks 14 pass through the mounting frame 1 and are fixedly connected to the top of the movable plate 3. The top of the mounting frame 1 is provided with a moving groove that is adapted to the connecting block 14.

[0033] A lead screw 15 is rotatably mounted on the top of the mounting bracket 1. The lead screw 15 is threadedly connected to the adjusting plate 13. A mounting box 16 is fixedly mounted on the top of the mounting bracket 1. The end of the lead screw 15 near the mounting box 16 passes through the mounting box 16 and is rotatably connected to the inner wall of the mounting box 16.

[0034] The mounting box 16 is equipped with a worm gear 17, which is fixedly sleeved on the outer wall of the lead screw 15. The mounting box 16 is equipped with a turntable 18, and a worm 19 is fixedly installed on the outer wall of the turntable 18. The end of the worm 19 passes through the mounting box 16 and is rotatably connected to the inner wall of the mounting box 16. The worm gear 17 and the worm 19 are meshed together.

[0035] As can be seen from the above, the adjusting plate 13 at the top of the movable plate 3 is fixedly connected to the movable plate 3 through the connecting block 14. The connecting block 14 passes through the movable groove at the top of the mounting frame 1, so that the adjusting plate 13 can slide stably on the mounting frame 1. The lead screw 15 is installed on the top of the mounting frame 1 and is connected to the adjusting plate 13 by threads. When it is necessary to adjust the position of the movable plate 3, the worm 19 can be rotated by the turntable 18 on the mounting box 16. The worm 19 meshes with the worm wheel 17 in the mounting box 16. The worm wheel 17 is fixedly sleeved on the outer wall of the lead screw 15, thereby driving the lead screw 15 to rotate. Due to the threaded connection between the lead screw 15 and the adjusting plate 13, the rotation of the lead screw 15 will be converted into the linear movement of the adjusting plate 13 along the axial direction of the lead screw 15, thereby driving the movable plate 3 to slide at the bottom of the mounting frame 1. Through the self-locking property of the worm wheel 17 and the worm 19, the movable plate 3 remains stable after adjustment, without the need for additional locking devices, which is convenient and quick, and effectively improves the applicability and ease of operation of the bracket.

[0036] Example 2:

[0037] refer to Figure 1 and Figure 2 As shown, the hoisting assembly includes a fixed frame 20 fixedly installed on the top of the mounting frame 1, and an electric hoist 21 fixedly installed on the outer wall of the fixed frame 20.

[0038] As can be seen from the above, the fixed frame 20 is installed on the top of the mounting frame 1, and the electric hoist 21 is fixedly installed on the outer side wall of the fixed frame 20. As a light and small lifting device, the electric hoist 21 can drive the wire rope or chain to lift heavy objects vertically through the motor. At the rescue site, the operator can remotely control the start and stop of the electric hoist 21 to easily lift rescue equipment, materials or trapped personnel, greatly reducing the physical burden on rescuers and improving rescue efficiency.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
