Description

Technical Field

[0001] The utility model relates to the field of firefighting and rescue, in particular to an umbrella-shaped demolition device. Background Art

[0002] At present, warehouses, factories and other buildings use more colored steel plates. However, when such buildings need rescue in case of accidental fire, most of the time of firefighters is spent on breaking and dismantling the colored steel plates to extinguish the fire, block the fire and exhaust smoke. Sometimes the collapsed colored steel plates need to be broken and extinguished at the same time, otherwise the water gun cannot directly hit the fire point, which is extremely inefficient and the rescue time is poor. There are also some demolition device structures for dismantling colored steel plates in the prior art, such as some existing umbrella-shaped demolition devices for colored steel plates, which use springs to open the umbrella structure. After the umbrella is opened and dismantled, it cannot be retracted by itself, resulting in the inability to remove it from the colored steel plates. A cutting machine is needed to cut the colored steel plates, which wastes time. Utility Model Content

The expanding part 4 includes a plate body 14. A rotating shaft 13 is provided at the end of the plate body 14. The part where the rotating shaft 13 is provided can be stuck in the card slot 10, and the rotating shaft 13 is stuck in the card slot 10. The connecting column 9 is used for threaded connection with the hand-held part 2. And in order to increase the firmness, a locking nut 12 can be threadedly connected to the end of the threaded part of the hand-held part 2.

[0027] As Figure 4 , Figure 5As shown, a push-pull inner rod 3 passes through the center of the hand-held part 2, and the push-pull inner rod 3 passes through the end of the hand-held part 2 to the other end and is connected with a pushing block 5. The push-pull inner rod 3 is connected to the pushing block 5 by a threaded connection. The pushing block 5 is located inside the conical block 8 and has an annular groove 6 on the surface; a connecting column 9 and the middle of the conical block 8 are provided with a connecting groove 11, the push-pull inner rod 3 extends into the connecting groove 11, and the clamping groove 10 is connected with the connecting groove 11. A protrusion 15 is provided at the end of the plate body 14 of the expansion part 4, and the protrusion 15 passes through the lower part of the clamping groove 10 and extends into the annular groove 6, and the protrusion 15 of the expansion part 4 has a gap 7 on the width of the annular groove 6. When the push-pull inner rod 3 pulls the pushing block 5, the pushing block 5 controls one end of the expansion part 4 to rotate and expand in the direction away from the hand-held part 2, and when the push-pull inner rod pushes the pushing block, the pushing block controls the expansion part to rotate and retract toward the hand-held part.

[0028] The protrusion 15 is provided with a gap 7 between the widths of the annular groove 6. When the push block 5 is pulled, one end of the protrusion 15 is pressed against the inner side of the annular groove 6. When the push block 5 is further pulled, the protrusion 15 rotates along the rotating shaft 13, and the opening portion 4 is opened into an umbrella shape outside the puncturing portion 1.

[0029] Among them, the two ends of the protrusion 15 located in the annular groove 6 are respectively provided with wedge surfaces 16, and the wedge surfaces 16 respectively face the two ends of the annular groove 6. When the protrusion 15 is pressed on the end of the annular groove, the wedge surface 16 of the protrusion 15 fits with the end surface of the annular groove 6 to ensure stability.

[0030] A limiting pin 17 is provided on the push block at one end of the annular groove 6 close to the push-pull inner rod 3 . The limiting pin 17 is located at the side of the protrusion 15 and is used to limit the expansion portion 4 .

[0031] In addition, in order to extend the hand-held part 2, the hand-held part 2 includes at least one rod body, and the outside of the rod body is provided with an external thread. When there are multiple rod bodies, adjacent rod bodies are connected by a connecting sleeve 19. Similarly, the push-pull inner rod 3 can also be provided with multiple rod bodies for connection, and the end of the push-pull inner rod 3 extending out of the hand-held part 2 is provided with a hanging ring 18 to facilitate the connection of the pulling device.

[0032] The demolition tool is used as follows: the user holds the hand-held part 2 and thrusts the piercing part 1 toward the color steel plate or other external wall structure to pierce and penetrate it. At this time, the push-pull inner rod 3 is pulled, and the push-pull inner rod 3 props up and opens the opening part 4, so that the opening part 4 is opened and pressed against the inner side of the color steel plate external wall. The user then pulls the hand-held part 2 in the opposite direction to pull down the color steel plate wall to achieve demolition. After demolition, the push-pull inner rod 3 is pushed, and the opening part 4 is recovered and can be removed from the color steel plate.
