Description
Technical Field
[0001] This utility model relates to the field of demolition tools, and in particular to an outdoor emergency rescue demolition device. Background Technology
[0002] Wilderness fire rescue refers to fire rescue activities conducted in the wild environment, which usually involves the handling of fires or other emergencies in natural environments such as mountains, forests, and grasslands. When conducting outdoor fire rescue, firefighters usually need to carry demolition tools to quickly break through obstacles. However, conventional demolition tools have simple structures and limited functions.
[0003] Existing patent CN218420694U describes a multi-functional demolition device. Used by a handheld handle, the device features a demolition axe and saw at one end, offering multiple functions. In complex rescue environments, firefighters can simply hold the handle and use the axe and saw for chopping and cutting. A demolition shovel at the other end of the handle can also be used to remove objects, significantly improving safety and convenience for firefighters during firefighting or sabotage operations. It is easy to use; in spaces with damaged circuits, a control switch can be activated to illuminate the surrounding environment, facilitating demolition. It also benefits rescue operations in dimly lit rooms. Outdoors, the demolition shovel can be inserted into the ground, positioning the handle vertically, and the flashing light serves as a warning during rescue operations. This increases the device's functionality, reduces the load on rescuers' tools, and minimizes their physical exertion.
[0004] However, when using a multi-functional demolition device with an existing patent, the sharp edge of the demolition axe at the end of the handheld handle always faces outwards, making it very easy for firefighters to injure themselves or their teammates when they move forward holding the handheld handle. Utility Model Content
[0005] The purpose of this utility model is to provide an outdoor emergency rescue demolition device that solves the problem that the sharp edge of the demolition axe at the end of the handheld pole always faces outward, making it easy for firefighters to injure themselves or their teammates when they move forward holding the handheld pole.
[0006] To achieve the above objectives, this utility model provides an outdoor emergency rescue demolition device, including a main pole, a mounting base, and a demolition axe. The mounting base is fixedly mounted on the main pole, and the demolition axe is fixedly mounted on the mounting base. It also includes a folding device, which comprises a secondary pole, a lifting frame, a fixing sleeve, and a connecting assembly. The secondary pole is rotatably mounted on the main pole via the connecting assembly. The lifting frame is fixedly mounted on the secondary pole and located at the end of the secondary pole furthest from the main pole. The fixing sleeve is threadedly engaged with the secondary pole.
[0007] The connecting assembly includes a fixed base, a rotating base, a connecting shaft, and a locking component. The fixed base is fixedly installed on the main rod and located at the end of the main rod away from the demolition axe. The connecting shaft is fixedly installed on the fixed base. The rotating base is fixedly installed on the secondary rod and is rotatably connected to the connecting shaft.
[0008] The locking component includes a stud and a nut, with the stud penetrating the connecting shaft and the nut threadedly engaging with the stud.
[0009] The folding device further includes a rotating assembly, which comprises a rotating ring and a fixing rod. The rotating ring is fixedly mounted on the fixing sleeve, and the fixing rod is fixedly mounted on the rotating ring.
[0010] The auxiliary rod is also provided with a grip sleeve and anti-slip texture. The grip sleeve is fixedly installed on the auxiliary rod, and the anti-slip texture is provided on the grip sleeve.
[0011] This utility model discloses an outdoor emergency rescue demolition device. In use, rotating the main rod or auxiliary rod keeps them upright. Then, rotating the fixing sleeve moves it upwards through its threaded engagement with the auxiliary rod until it engages with the main rod's thread. At this point, the position of the main rod and auxiliary rod remains fixed. By gripping the holding sleeve and swinging the auxiliary rod, the demolition axe on the main rod can be used to break through obstacles. When the device needs to be moved as a whole, rotating the fixing sleeve in the opposite direction causes it to slide down. Through the rotational engagement of the fixing seat and the rotating seat, the main rod and auxiliary rod are folded. Then, tightening the nut on the connecting shaft prevents relative rotation between the auxiliary rod and the main rod. At this point, the sharp edge of the demolition axe on the main rod faces the auxiliary rod, thus reducing the risk of injury to firefighters and team members when moving the device as a whole.

Detailed Implementation
[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0018] The first embodiment of this application is as follows:
[0019] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of an outdoor emergency rescue and demolition device according to this utility model. Figure 2 This is a schematic diagram showing the connection between the main rod and the auxiliary rod of this utility model. Figure 3 yes Figure 2 An enlarged schematic diagram.
[0020] This utility model provides an outdoor emergency rescue demolition device, including a main pole 101, a mounting base 102, and a demolition axe 103. It also includes a folding device, which comprises a secondary pole 104, a lifting frame 105, a fixing sleeve 106, and a connecting assembly. The connecting assembly includes a fixing seat 107, a rotating seat 108, a connecting shaft 109, and a locking component. The locking component includes a stud 110 and a nut 111. The folding device also includes a rotating assembly, which includes a rotating ring 112 and a fixing rod 113. The secondary pole 104 is also provided with a grip sleeve 114 and anti-slip texture 115. This solution solves the problem that the sharp edge of the demolition axe at the end of the handheld pole always faces outwards, making it easy for firefighters to injure themselves or their teammates when moving forward with the handheld pole. This solution can be used in outdoor emergency rescue demolition scenarios.
[0021] In this embodiment, by folding the main rod 101 and the secondary rod 104, the sharp edge of the demolition axe 103 on the main rod 101 faces the secondary rod 104, thereby making it less likely for the demolition axe 103 to cause injury to the firefighter or team members when the firefighter moves forward with the device as a whole.
[0022] The auxiliary rod 104 is rotatably mounted on the main rod 101 via the connecting assembly. The lifting frame 105 is fixedly mounted on the auxiliary rod 104 and located at the end of the auxiliary rod 104 away from the main rod 101. The fixing sleeve 106 is threadedly engaged with the auxiliary rod 104. Both the auxiliary rod 104 and the main rod 101 are threaded. The lifting frame 105 is welded to the auxiliary rod 104. The inner side of the fixing sleeve 106 is threaded. The connecting assembly enables a rotatable connection between the main rod 101 and the auxiliary rod 104. The rotatable engagement between the auxiliary rod 104 and the main rod 101 facilitates the lifting of the auxiliary rod. The auxiliary rod 104 and the main rod 101 can be folded or unfolded. When the demolition axe 103 is needed, the main rod 101 and the auxiliary rod 104 are unfolded, and the fixing sleeve 106 is rotated so that the fixing sleeve 106 moves to the hinge point of the main rod 101 and the auxiliary rod 104, so that the main rod 101 and the auxiliary rod 104 remain upright. By folding the main rod 101 and the auxiliary rod 104, the sharp edge of the demolition axe 103 on the main rod 101 faces the auxiliary rod 104, so that when firefighters move forward with the device as a whole, the demolition axe 103 is less likely to cause injury to themselves and their teammates.
[0023] Secondly, the fixed seat 107 is fixedly installed on the main rod 101 and located at the end of the main rod 101 away from the demolition axe 103; the connecting shaft 109 is fixedly installed on the fixed seat 107; the rotating seat 108 is fixedly installed on the secondary rod 104 and rotatably connected to the connecting shaft 109. The fixed seat 107 is located on both sides of the end of the main rod 101, and the rotating seat 108 is located between the two fixed seats 107. The connecting shaft 109 is a cylindrical structure. The locking assembly can limit the rotation between the fixed seat 107 and the rotating seat 108. Through the rotational engagement between the fixed seat 107 and the rotating seat 108, the rotation between the main rod 101 and the secondary rod 104 is realized.
[0024] Furthermore, the stud 110 passes through the connecting shaft 109; the nut 111 is threadedly engaged with the stud 110, and the axis of the stud 110 coincides with that of the connecting shaft 109. The inner side of the nut 111 is threaded. By tightening the nut 111, the nut 111 moves on the stud 110, causing the nut 111 to press against the fixed seat 107. The fixed seat 107 further presses against the rotating seat 108. Through the friction between the fixed seat 107 and the rotating seat 108, it is ensured that after the nut 111 is tightened, the fixed seat 107 and the rotating seat 108 cannot rotate relative to each other.
[0025] Furthermore, the rotating ring 112 is fixedly mounted on the fixed sleeve 106; the fixed rod 113 is fixedly mounted on the rotating ring 112, and the rotating ring 112 is welded to the outside of the fixed sleeve 106; the fixed rod 113 is arranged in a ring around the outer periphery of the rotating ring 112. By rotating the fixed rod 113, the rotating ring 112 rotates, and the rotating ring 112 drives the fixed sleeve 106 to rotate, thereby facilitating the rotation of the fixed sleeve 106.
[0026] Finally, the grip sleeve 114 is fixedly installed on the secondary rod 104; the anti-slip texture 115 is provided on the grip sleeve 114, the grip sleeve 114 is made of rubber, and the grip sleeve 114 is fixed to the secondary rod 104 by adhesive. The anti-slip texture 115 makes it less likely to slip when gripping the grip sleeve 114, and the grip sleeve 114 makes it easier to grip the secondary rod 104.
[0027] In this embodiment, during use, the main rod 101 or the secondary rod 104 is rotated to keep them upright. Then, the fixing sleeve 106 is rotated, causing it to move upwards through its threaded engagement with the secondary rod 104 until it engages with the main rod 101. At this point, the position between the main rod 101 and the secondary rod 104 remains fixed. By gripping the grip sleeve 114 and swinging the secondary rod 104, the demolition axe 103 on the main rod 101 can be used to break down obstacles. When the entire device needs to be carried, [further details about movement are needed]. Rotate the fixed sleeve 106 in the opposite direction to make it slide down. Through the rotational engagement of the fixed seat 107 and the rotating seat 108, the main rod 101 and the auxiliary rod 104 are folded. Then tighten the nut 111 on the connecting shaft 109 so that the auxiliary rod 104 and the main rod 101 cannot rotate relative to each other. At this time, the sharp edge of the demolition axe 103 on the main rod 101 faces the side of the auxiliary rod 104, so that when the firefighter moves forward with the device as a whole, the demolition axe 103 is less likely to cause injury to himself and his teammates.
[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
