DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The utility model provides an embodiment: a subway maintenance personnel transportation vehicle, including a vehicle body 1, a placement groove 2 is opened on the rear side of the top wall of the vehicle body 1, and both side walls of the placement groove 2 are opened with moving grooves 12, and the front and rear parts of the two moving grooves 12 that are far away from each other are fixedly connected with springs 14, and the close ends of the springs 14 on both sides are fixedly connected with moving plates 13, and the close sides of the two moving plates 13 are fixedly connected with connecting strips 3, and the front and rear walls of the two connecting strips 3 are opened with grooves 18, and the rear wall of the rear groove 18 is rotated. A rotating shaft 17 is connected, and the front ends of the two rotating shafts 17 are rotatably connected to the front wall of the front groove 18. The middle parts of the two rotating shafts 17 are fixedly connected to the baffle 4. The outer peripheries of the front and rear ends of the two rotating shafts 17 are provided with torsion springs 16. One end of the multiple torsion springs 16 is fixedly connected to the inner wall of the groove 18, and the other ends of the multiple torsion springs 16 are fixedly connected to the baffle 4; guide rods 15 are passed through both sides of the two moving plates 13, and both ends of the multiple guide rods 15 are fixedly connected to the inner wall of the moving groove 12, and multiple springs 14 are arranged on the outer periphery of the guide rods 15;

[0034] Specifically, when the staff needs to place the toolbox, the toolbox can be directly placed on the baffle 4. When the toolbox is pressed down, it will push the baffle 4 to rotate around the rotating shaft 17 and open, so that the toolbox can be placed in the placement groove 2. And when the baffle 4 rotates, it will pull the torsion spring 16 connected to the front and back sides. Therefore, after the toolbox is completely placed, under the action of the torsion spring 16, the baffle 4 can be pulled back to reset, thus squeezing the two sides of the toolbox to increase the friction force, and then the toolbox can be limited and fixed. When the staff only needs to place some tools, the staff can directly pull the baffle 4 to both sides to make it slide into the moving groove 12, so that the placement groove 2 can be opened and tools can be placed. And when the baffle 4 moves in the moving groove 12, it will drive the connecting strip 3 to move into the moving groove 12 through the rotating shaft 17. When the connecting strip 3 moves, it will drive the connected moving plate 13 to move into the moving groove 12 and compress the first spring 14. Therefore, after the baffle 4 is released, under the action of the first spring 14, the baffle 4 can be pushed back and extended to close the placement groove 2. And under the action of the guide rod 15, the moving plate 13 and the first spring 14 can be limited, ensuring the stability of the movement of the moving plate 13 and preventing the first spring 14 from bending after being compressed, so as to prevent the tools from falling due to bumps and prevent dust from entering the placement groove 2. Furthermore, it can achieve the effect of placing tools or toolboxes according to different usage situations, fixing the toolbox, preventing the tools from falling due to bumps, and preventing dust from entering when storing tools.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3 , in the middle of the rear wall of the vehicle body 1, a connecting plate 5 is fixedly connected. A connecting shaft 8 is slidably connected in the connecting plate 5. A clamping groove 21 is provided on the outer circumference of the upper part of the connecting shaft 8. A storage cart 9 is fixedly connected to the rear end of the connecting shaft 8. A sliding groove 7 is provided on the top wall of the connecting plate 5. A sliding block 6 is slidably connected in the sliding groove 7. A clamping block 22 is fixedly connected to the rear wall of the sliding block 6. The clamping block 22 is clamped in the clamping groove 21. A second spring 20 is fixedly connected to the front wall of the sliding block 6. The front end of the second spring 20 is fixedly connected to the front wall in the sliding groove 7; A limiting rod 19 passes through the lower part of the sliding block 6. The front and rear ends of the limiting rod 19 respectively pass through the front and rear end walls of the sliding block 6 and are fixedly connected to the front and rear walls in the sliding groove 7. The second spring 20 is arranged on the outer circumference of the limiting rod 19;

[0036] Specifically, when it is necessary to carry more materials to maintain the subway, the staff can put more materials into the storage cart 9, and then insert the connecting shaft 8 connected to the storage cart 9 into the connecting plate 5, and the block 22 will be squeezed during the insertion process. Since the upper side of the block 22 is an inclined surface, the squeezing of the connecting shaft 8 will push the block 22 to move. Since the block 22 moves, it will drive the slider 6 to move in the slide groove 7 and compress the spring 20. Therefore, after the connecting shaft 8 is fully inserted into the connecting plate 5, the spring 20 can push the slider 6 to drive the block 22 to reset and snap into the slot 21 to limit the connecting shaft 8. Under the action of the limiting rod 19, the slider 6 can be prevented from falling off the slide groove 7 to ensure the stability of the movement of the slider 6, thereby achieving the effect of facilitating the installation of the storage cart 9 according to different needs to increase the material carrying capacity.

[0037] Reference Figure 1 , Figure 2 and Figure 4 A front end 10 is fixedly connected to the front middle of the top wall of the vehicle body 1, and a headlight 11 is fixedly connected to the front wall of the head end 10; a bracket 23 is fixedly connected to the middle of the top wall of the vehicle body 1, and a seat cushion 24 is fixedly connected to the top wall of the bracket 23;

[0038] Specifically, the front end 10 is provided to facilitate the staff to control the transport vehicle to a certain extent, and the headlights 11 can illuminate the environment in front of the transport vehicle to facilitate observation by the staff; the bracket 23 and the seat cushion 24 are provided to enable the staff to sit on the seat cushion 24 to drive, thereby providing convenience for the staff.

[0039] Working principle: In actual use, when the staff needs to place a tool box, they can directly place the tool box on the baffle 4 and push the baffle 4 to rotate and open it around the rotating shaft 17, so that the tool box can be placed in the placement slot 2, and under the action of the torsion spring 16, the baffle 4 can be pulled to squeeze the two sides of the tool box, so that the tool box can be limited. When the staff only needs to place some tools, the staff can pull the baffle 4 to both sides to slide it into the movable slot 12, so that the placement slot 2 can be opened and the tools can be placed, and under the action of the spring 14, the baffle 4 can be pushed to return and extend to close the placement slot 2, so as to prevent the tools from falling due to bumps and prevent dust from entering. Into the placement slot 2, so as to achieve the effect of being able to place tools or tool boxes according to different usage conditions, and being able to fix the tool box and prevent the tools from falling due to bumps or prevent dust from entering when storing tools; in addition, when it is necessary to carry more materials to maintain the subway, the staff can put more materials into the storage cart 9, and insert the connecting shaft 8 into the connecting plate 5, and in the process of insertion, the block 22 will be squeezed to move, so after the connecting shaft 8 is fully inserted into the connecting plate 5, the spring 20 can push the block 22 to be stuck in the slot 21 to limit the connecting shaft 8, thereby achieving the effect of facilitating the installation of the storage cart 9 according to different needs to increase the material carrying capacity.
