[0001] The utility model relates to the technical field of fire rescue, in particular to a rescue device. Background Technique

[0002] A Chinese patent discloses a fire rescue device for smart cities (authorization publication number CN109529212B). After the victim sits properly, the winding mechanism cooperates with the limiting mechanism to fix the cloth belt. The operation is simple, convenient for storage, and reduces the floor area. After determining the lengths of the two cloth belts and fixing them, the cloth belts are passed through the shoulders of the rescue personnel and fixed to the clamping mechanism, and then the whole structure can be carried on the back. The installation is fast. However, combined with the accompanying drawings of the specification and the content in the specification, it can be seen that in the above rescue device, the trapped person sits on the bottom plate, and then the rescue personnel carry the whole rescue device and the trapped person on the back to complete the rescue work. Therefore, the rescue personnel not only need to overcome the gravity of the whole rescue device, but also need to overcome the gravity of the trapped person to complete the rescue work, which will undoubtedly be time-consuming and laborious and cannot reduce the rescue difficulty of the rescue personnel.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 4 , the present invention provides a rescue device, including a base 1. Two slide grooves 2 are horizontally opened at the top of the base 1, and universal wheels 3 are fixedly connected to the four corners at the bottom of the base 1. Two shock-absorbing mechanisms 4 are also installed on the top of the base 1. The shock-absorbing mechanism 4 includes a first cross bar 41, a first bracket 42 and a second bracket 43. Vertical bars 411 are fixedly connected to both ends of the first cross bar 41. The bottoms of the two vertical bars 411 are respectively slidably sleeved with a first support rod 412 and a second support rod 413. The bottom of the first cross bar 41 is hinged with the first bracket 42 and the second bracket 43. The bottom end of the first bracket 42 is hinged with a first adjusting ring 44, and the bottom end of the second bracket 43 is hinged with a second adjusting ring 45. Slide rods 46 are fixedly connected to the bottoms of the first adjusting ring 44 and the second adjusting ring 45. A second cross bar 47 is fixedly connected between the first support rod 412 and the second support rod 413. A first spring 48 and a second spring 49 are sleeved outside the second cross bar 47. The top ends of the vertical bars 411 are fixedly connected to the bottom corners of the carrying seat 51, and the bottom ends of the first support rods 412 are fixedly connected to the top corners of the base 1. The slide rods 46 are slidably connected inside the slide grooves 2. One end of the first spring 48 is fixedly connected to the first adjusting ring 44, and the other end of the first spring 48 is fixedly connected to the first support rod 412. One end of the second spring 49 is fixedly connected to the second adjusting ring 45, and the other end of the second spring 49 is fixedly connected to the second support rod 413. The two shock-absorbing mechanisms 4 can play a role in shock absorption for the entire rescue device, increasing the comfort of the trapped person during the rescue process and preventing the trapped person from being injured again due to road bumps.

[0020] At the top of two shock-absorbing mechanisms 4, a bearing mechanism 5 is installed. The bearing mechanism 5 includes a bearing seat 51, a guide groove 52, and a backrest plate 53. Guide grooves 52 penetrate through both sides of the bearing seat 51, and a backrest plate 53 is hinged at the front side of the top of the bearing seat 51. Both sides of the backrest plate 53 are rotatably connected to a stop rod 54 through a pin shaft. One end of each of the two stop rods 54 is hinged to a fastening block 55. An integrally connected guide block 56 is provided on the fastening block 55, and a bolt 57 threadedly penetrates through the interior of the fastening block 55. The guide block 56 is of a "T" shape and is adapted to the guide groove 52. The guide block 56 is slidably connected inside the guide groove 52. One end of the bolt 57 abuts against the side wall of the bearing seat 51. The two fastening blocks 55 are respectively located on both sides of the bearing seat 51. A push rod is also fixedly connected to the bearing seat 51. When the bearing mechanism 5 is unfolded, it is convenient for the trapped person to directly sit on the bearing seat 51, and then the rescuer can push the entire rescue device. In combination with the universal wheels 3, the rescue of the trapped person can be completed quickly and efficiently without having to carry the entire rescue device on the back, which can greatly reduce the rescue difficulty of the rescuer and make the rescuer more time-saving and labor-saving during actual rescue. When the rescue is over, the bearing mechanism 5 can be retracted and will not occupy extra space, which is conducive to carrying.

[0021] Working principle: When using this device, the rescuer can move the entire rescue device to the rescue location by pushing it. Under the action of the universal wheels 3, then pull the two fastening blocks 55 forward. At this time, the stop rods 54 can be driven to move, so that the backrest plate 53 can be slowly unfolded from the bearing seat 51. When the backrest plate 53 moves to the ideal position, tighten the bolt 57. At this time, the fastening block 55 can be fixed on the bearing seat 51. Then help the trapped person to the bearing seat 51 and make his back abut against the backrest plate 53. The trapped person can be blocked by the stop rods 54 on both sides to prevent the trapped person from falling off the bearing seat 51 during the rescue process. Then the user can hold the push rod on the bearing seat 51 to move the entire rescue device. When the road surface during the rescue is uneven, the first cross bar 41 and the two vertical rods 411 can be driven to move up and down, so that the first bracket 42 and the second bracket 43 can be driven to move. After the first bracket 42 and the second bracket 43 move, the first adjusting ring 44 and the second adjusting ring 45 can be driven to slide on the second cross bar 47, so as to squeeze the first spring 48 and the second spring 49 and make them deform, thus playing a role in shock absorption. And the entire rescue device can be shock-absorbed by the two shock-absorbing mechanisms 4, increasing the comfort of the trapped person during the rescue process and preventing the trapped person from being injured again due to road bumps.

[0022] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
