Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 5As shown in the figure, a portable mine safety rescue device includes two positioning plates 1. The two positioning plates 1 are connected to each other through a rotating shaft 2. Through the rotating shaft 2, the two positioning plates 1 can rotate relative to each other, so that the two positioning plates 1 can be used horizontally or in a V shape. When the two positioning plates 1 are horizontal, they can be used as a stretcher. When forming a V shape, they can be used as a protective shielding frame to shield falling objects from above. One end of the positioning plate 1 is provided with a retractable groove, and an extension plate 3 is slidably inserted into the retractable groove. The extension plate 3 is connected to the positioning plate 1 through a push-pull adjustment assembly 4. During use, the push-pull adjustment assembly 4 is controlled to make the extension plate 3 slide in the retractable groove. When used as a stretcher, it is suitable for wounded people of different heights and is more convenient to store. The top of the positioning plate 1 and the extension plate 3 are provided with a foldable dust shield 5. Under the action of the foldable dust shield 5, falling stones and dust can be shielded to avoid secondary injuries to the wounded when rescuing the wounded by turning them. The two ends of the bottom of the foldable dust shield 5 are fixedly connected to the positioning plate 1 and the extension plate 3 respectively through a pin-type fixed connection assembly 6, so as to facilitate the disassembly and assembly of the foldable dust shield 5, making it more flexible to use and more convenient to carry.

[0022] The push-pull adjustment assembly 4 includes a square installation frame 401 and a transverse threaded rod 402. The transverse threaded rod 402 is rotatably installed on the inner wall of one end of the square installation frame 401 through a rotating joint 403. One end of the transverse threaded rod 402 rotatably passes through the square installation frame 401 and is fixedly installed with a screwing handle 404. A threaded slider 405 is installed on the transverse threaded rod 402. The threaded slider 405 is slidably clamped in the square installation frame 401. A U-shaped connecting rod 406 is fixedly installed on the threaded slider 405. One end of the U-shaped connecting rod 406 is fixedly connected to one end of the extension plate 3. During use, the screwing handle 404 is controlled to make the transverse threaded rod 402 rotate in the square installation frame 401 through the rotating joint 403, driving the threaded slider 405 to slide in the square installation frame 401, so as to drive the extension plate 3 to slide in the positioning plate 1 through the U-shaped connecting rod 406.

[0023] The foldable dust shield 5 is composed of a first arc-shaped side frame 501 and a second arc-shaped side frame 502. At both ends of the bottom of the first arc-shaped side frame 501 and the second arc-shaped side frame 502, L-shaped connecting blocks 503 are fixedly installed. The L-shaped connecting blocks 503 are fixedly connected to the positioning plate 1 and the extension plate 3 through a plug-in type fixed connection component 6. A soft shielding cloth 504 is fixedly installed on the inner walls of the first arc-shaped side frame 501 and the second arc-shaped side frame 502. When in use, when the first arc-shaped side frame 501 and the second arc-shaped side frame 502 move away from each other, the soft shielding cloth 504 is tensioned and unfolded, facilitating the unfolded use. At the same time, when the first arc-shaped side frame 501 and the second arc-shaped side frame 502 approach each other, the soft shielding cloth 504 is retracted, realizing the overall storage of the foldable dust shield 5 and facilitating the carrying.

[0024] The plug-in type fixed connection component 6 includes an embedded head 601, which is fixed on the positioning plate 1 and the extension plate 3. The L-shaped connecting block 503 is inserted into the embedded head 601. A U-shaped connecting block 602 is fixedly installed on the side wall of the embedded head 601. A connecting pin rod 603 is slidably inserted into the U-shaped connecting block 602. One end of the connecting pin rod 603 passes through the embedded head 601 and is inserted into a connecting pin hole on the L-shaped connecting block 503. The other end of the connecting pin rod 603 is fixedly installed with a lifting handle 604. An annular cushion block 605 is sleeved on the connecting pin rod 603. The annular cushion block 605 is elastically connected to the U-shaped connecting block 602 through a positioning spring 606. When in use, under the action of the positioning spring 606, the annular cushion block 605 drives the connecting pin rod 603 to be fixedly inserted into the connecting pin hole, so that the L-shaped connecting block 503 is fixed on the embedded head 601, facilitating the fixing of the foldable dust shield 5 on the positioning plate 1 and the extension plate 3. At the same time, by controlling the lifting handle 604, the connecting pin rod 603 is disengaged from the connecting pin hole, facilitating the separation of the L-shaped connecting block 503 from the embedded head 601, thereby facilitating the removal of the foldable dust shield 5 from the positioning plate 1 and the extension plate 3, facilitating the disassembly and assembly of the foldable dust shield 5, and making the use more flexible.
