Description

Technical Field

[0001] This utility model relates to the field of transportation vehicles, and in particular to an auxiliary transportation vehicle that can be quickly assembled and disassembled. Background Technology

[0002] In the transportation field, one application scenario involves unloading objects from a transport device and moving them to the required application location. For example, during firefighting operations, after arriving at the destination, the water hoses on the fire truck need to be removed and moved to the location where the fire needs to be extinguished. A common problem encountered in actual use is that when the fire site is located in an alley far from the main road, the fire truck cannot approach it, and firefighters need to manually remove the water hoses and move them into the alley. Due to the length and weight of the water hoses, the movement requires a lot of manpower and takes a long time, affecting firefighting efficiency. In view of this, it is necessary to design an auxiliary transport vehicle that can be quickly disassembled and installed from the fire truck. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a quick-assembly auxiliary transport vehicle for assisting in loading objects. This vehicle is detachably connected to the main transport device via an upper and lower locking mechanism, automatically fastened by elastic force, and quickly detached by pressing down, thereby effectively improving the efficiency of object use and transportation.

[0004] The technical solution adopted by this utility model is as follows: A quick-assembly and disassembly auxiliary transport vehicle includes a support component, a connecting component, a bracket, a pressure rod, a connecting transmission component, and a transmission component. The support component is mounted on an external mechanism. The connecting component comprises two sets, spaced apart and movably inserted into the support component. The bracket comprises two brackets, each inserted downwards at an angle within the connecting component. One end of each bracket is movably engaged with the support component, while the other end extends outwards to form a support frame. One end of the transmission component is movably mounted on the connecting component, while the other end extends upwards at an angle. The connecting transmission component is rotatably connected to the side wall of the bracket and the other end of the transmission component, and connected to the transmission component via a return spring. In its natural state, the spring force of the return spring pulls the other end of the transmission component upwards, causing one end of the transmission component to tilt upwards and clamp onto the support component. The pressure rod is fixed to the connecting transmission component. When the pressure rod is pushed downwards, it pushes the other end of the transmission component downwards through the connecting transmission component, causing one end of the transmission component to disengage downwards from the support component.

[0005] Preferably, the support assembly includes a support rod, a buckle, and a support, wherein the support rod is horizontally mounted on the external structural mechanism; the buckle includes two buckles, which are fixed to the support rod at a distance; and the support includes two supports, which are respectively fixed to the two buckles.

[0006] Preferably, the support includes a side plate, a first support shaft, a second support shaft, and a third support shaft. The side plate comprises two pieces, which are arranged vertically parallel and spaced apart, forming a second through groove between them. The first support shaft, the second support shaft, and the third support shaft are respectively arranged in the second through groove and spaced apart in a downward direction. The third support shaft is provided with a third groove F with an inwardly recessed annular structure.

[0007] Preferably, the connecting assembly includes a support plate and guide rollers, wherein the support plate comprises two pieces, which are vertically spaced apart and form a first through groove between them; the guide rollers comprise two sets, which are rotatably mounted on the support plate at intervals and located within the first through groove, forming a vertical slide between the two sets of guide rollers; a sliding groove penetrating its side wall is provided on one side of the support plate, and the sliding groove is arranged corresponding to the vertical slide.

[0008] Preferably, the transmission assembly includes a rocker arm, a seat, and a connecting roller. One end of the rocker arm has a connecting roller on its sidewall. The connecting roller extends through a slide groove into a first through groove and slides freely vertically within the groove. The seat is disposed within the first through groove and is movably inserted into a vertical slide rail. Guided and limited by a guide roller, the seat is fixed to the connecting roller. A second slot is provided at the top of the seat to allow it to be inserted and engaged with a first support shaft. The other end of the rocker arm extends upwards at an angle and is rotatably connected to the sidewall of the bracket.

[0009] Preferably, the bracket is a triangular frame structure, with one side of the bracket slidably inserted into the first through groove along the inclined direction. The lower part of this side is provided with a first slot with the opening facing downward. The first slot engages with the third slot from top to bottom and rotates freely within the third slot.

[0010] Preferably, the connecting transmission assembly includes a rotating seat, a first rotating shaft, and a second rotating shaft. The rotating seat is a triangular plate structure. The first rotating shaft is inserted at one corner of the rotating seat and connected to the side wall of the bracket, allowing the rotating seat to rotate freely around the first rotating shaft. The second rotating shaft is inserted at the other corner of the rotating seat and connected to the other end of the swing rod. The rotating seat and the swing rod are rotatably connected via the second rotating shaft. The pressure rod is connected to the triangular part of the rotating seat. When the pressure rod is pressed down, it causes the rotating seat to move downward around the first rotating shaft. The rotating seat then causes the other end of the swing rod to move downward via the second rotating shaft, causing the other end of the swing rod to slide downward through the connecting roller, thus disengaging the second slot from the first support shaft. One end of the return spring is connected to the side wall of the rotating seat, and the other end is connected to the swing rod. In its natural state, the spring force of the return spring pulls the other end of the swing rod upward.

[0011] Preferably, it further includes wheels, a housing, and a handle. The wheels consist of two parts, each rotatably mounted on the outer side wall of one of the two supports. The housing is positioned between the two supports, with its two sides connected to the inner side walls of the two supports, and its opening facing upwards for storage. The handle is a U-shaped rod structure, with its lower opening connected to the top of the two supports on both sides.

[0012] The beneficial effects of this utility model are as follows: This utility model addresses the shortcomings and deficiencies of existing technologies by independently developing and designing an auxiliary transport vehicle for assisting in loading objects. It is detachably connected to the main transport device via an upper and lower locking mechanism, automatically fastened by elastic force, and quickly detached by pressing down, effectively improving the efficiency of object use and transportation.

[0013] This utility model is applied to the field of transportation and aims to provide an auxiliary transport vehicle that can be quickly disassembled and assembled for assisting in the transport of objects or goods. This auxiliary transport vehicle is smaller in size than the main transport vehicle and can transport goods in relatively confined spaces after loading. For example, it can be applied to fire trucks. Before use, it is hung on the bumper of the fire truck (the support rod in this application), and a water pipe is filled inside. When used for firefighting, it can be quickly removed from the fire truck by detaching from the bumper and moving the water pipe to the fire destination, thereby effectively saving the physical strength of firefighters and effectively improving the efficiency of water pipe transportation.

[0014] Specifically, this utility model involves two buckles that are intermittently fastened to the support rod, and then the buckles are fixed to the support rod with screws. Simultaneously, supports are fixed to each of the two buckles, forming an integrated support structure. Two connecting components are inserted into the second through slots of the two supports. One side of the bracket is inserted into the first through slot between the two support plates of the connecting component, and its bottom has a first locking slot, which engages with the third support shaft of the support from above for bearing support. The lower end of the swing arm of the transmission component is connected to a seat via a connecting roller. The connecting roller slides freely up and down in the groove of the support plate, and the seat slides freely in the vertical slide formed between the two sets of guide rollers on the two support plates. In its natural state, the swing arm is pulled upwards by the elastic force of the return spring. The swing arm causes the insert to engage upwards onto the first support shaft of the bracket, thus fixing the entire vehicle body to the bracket through this interlocking mechanism. When the vehicle body needs to be removed, the operator presses down on the pressure rod, which causes the rotating seat connected to the transmission assembly to rotate downwards. This overcomes the spring force of the return spring, driving the swing arm to disengage the insert downwards from the first support shaft. The vehicle body then flips outwards and faces downwards (using the third support shaft as the rotation axis, rotating downwards on the third support shaft using the first slot of the bracket). The operator then pulls the lever outwards to detach the vehicle body from the support rod, achieving efficient and rapid detachment. After detachment, the vehicle body can quickly move the water pipes loaded in the box to its destination, saving physical effort while completing the rapid transportation of the water pipes.

When the pressure rod 6 is pushed downward, the pressure rod 6 pushes the other end of the transmission component 8 downward through the connecting transmission component 7, causing one end of the transmission component 8 to disengage downward from the support component.

[0031] The support assembly includes a support rod 1, a buckle 2, and a support 3. The support rod 1 is horizontally mounted on the external structural mechanism. There are two buckles 2, which are fixed to the support rod 1 at intervals. There are two supports 3, which are fixed to the two buckles 2 respectively.

Guided and limited by the guide roller 42, the seat 82 is fixed on the connecting roller 83. The top of the seat 82 has a second slot D for upward insertion and engagement with the first support shaft 32. The other end of the rocker arm 81 extends obliquely upward and is rotatably connected to the side wall of the bracket 5.

[0035] The bracket 5 is a triangular frame structure. One side of the bracket 5 is slidably inserted into the first through slot A along the inclined direction. The lower part of this side is provided with a first slot C with the opening facing downward. The first slot C is engaged in the third slot F from top to bottom and can rotate freely in the third slot F.

[0036] The connecting transmission assembly 7 includes a rotating base 71, a first rotating shaft 72, and a second rotating shaft 73. The rotating base 71 is a triangular plate structure. The first rotating shaft 72 is inserted at one corner of the rotating base 71 and connected to the side wall of the bracket 5, allowing the rotating base 71 to rotate freely around the first rotating shaft 72. The second rotating shaft 73 is inserted at the other corner of the rotating base 71 and connected to the other end of the swing rod 81, allowing the rotating base 71 and the swing rod 81 to be rotatably connected via the second rotating shaft 73. The pressure rod 6 is connected to the rotating base 71. At the triangular position of 1, when the pressure rod 6 is pressed down, the pressure rod 6 drives the rotating seat 71 to move downward around the first rotating shaft 72. The rotating seat 71 drives the other end of the swing rod 81 to move downward through the second rotating shaft 73, so that the other end of the swing rod 81 drives the insert 82 to slide downward through the connecting roller 83, so that the second slot D disengages downward from the first support shaft 32. One end of the return spring 74 is connected to the side wall of the rotating seat 71, and the other end is connected to the swing rod 81. In the natural state, the elastic force of the return spring 74 pulls the other end of the swing rod 81 upward.

This utility model is applied in the transportation field, aiming to provide a quickly detachable auxiliary transport vehicle for assisting in the transportation of objects or goods. This auxiliary transport vehicle is smaller in size than the main transport vehicle and can transport items in relatively confined spaces. For example, it can be applied to fire trucks.
