Description

Technical Field

[0001] This application relates to the field of material transport vehicle technology, and in particular to a material transport vehicle. Background Technology

[0002] In scenarios such as logistics and transportation, factory material turnover, and warehousing and handling, material transport vehicles are one of the core tools for achieving efficient material transfer.

[0003] Most existing transport vehicles have a single cargo compartment or fixed shelves, allowing heavy and light materials to be mixed and stacked. Heavy materials are easily crushed and damaged, and existing double shelves require heavy materials to be placed on the lower shelf and light materials on the upper shelf when separating materials. The existing double shelves cannot arrange heavy materials properly, which can easily cause the center of gravity of heavy materials to shift and pose a risk of tipping over.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a material transport vehicle that has the advantages of facilitating the inspection and unloading of heavier materials located below, and solves the problem that existing devices are inconvenient to inspect the layout when loading and unloading heavier materials.

[0006] The material transport vehicle provided in this application adopts the following technical solution: it includes a first mounting frame, a first hinge is fixedly connected to the outer surface of the first mounting frame, a second mounting frame is provided above the first mounting frame, the outer surface of the second mounting frame is fixedly connected to the first hinge, two insertion holes are opened on the upper surface of the first mounting frame, two second springs are fixedly connected to the inner wall of the second mounting frame, a connecting plate is fixedly connected to the bottom end of each second spring, an insertion rod is fixedly connected to the bottom surface of each connecting plate, each insertion rod and the outer surface of the connecting plate are slidably connected to the second mounting frame, the outer surface of each insertion rod is inserted into the corresponding insertion hole, and a push block is fixedly connected to the outer surface of each connecting plate.

[0007] By adopting the above technical solution, the first mounting bracket serves as the basic load-bearing component, with two insertion holes providing the mounting base. The second mounting bracket is fixed by the insertion holes and the insertion rod. The second mounting bracket is located above the first mounting bracket and is connected to the first mounting bracket by the first hinge. The second mounting bracket can rotate around the first hinge, facilitating the inspection of the material inside the first mounting bracket when there is no material in the second mounting bracket. By pushing the push block, the push block will drive the corresponding connecting plate to squeeze the corresponding second spring, causing the insertion rod to move out of the corresponding insertion hole. Similarly, when fixing the two, the first mounting bracket will squeeze the insertion rod to slide into the second mounting bracket until the insertion rod and the corresponding insertion hole are on the same central axis. At this point, the second spring will push the corresponding insertion rod into the insertion hole under its rebound force.

[0008] Preferably, the outer surface of the second mounting bracket is fixedly connected with a plurality of elastic plates, and the outer surface of each elastic plate is engaged with a corresponding connecting plate.

[0009] By adopting the above technical solution, during the process of pushing the connecting plate, the connecting plate can be fixed by the snap-fit ​​between the elastic plate and the corresponding connecting plate. The operator pushes the push block upward, causing the connecting plate and the plug rod to rise until the plug rod is completely disengaged from the plug hole. When the connecting plate rises to a specific height, the elastic plate automatically snaps into the corresponding position of the connecting plate due to its own elastic deformation, hooking and fixing the connecting plate. When the second mounting bracket rotates to the target position, the operator only needs to push the elastic plate upward or outward with a little force to unlock the fixing of the connecting plate.

[0010] Preferably, the inner walls of the first mounting frame and the second mounting frame are fixedly connected with a stop bar, and the interior of the first mounting frame and the second mounting frame are provided with two frame doors, and the inner wall of each frame door is fixedly connected with a mounting rod.

[0011] By adopting the above technical solution, the baffles are evenly arranged around the first mounting frame and the second mounting frame, and the baffles and mounting rods are arranged to close the first mounting frame and the second mounting frame, which facilitates blocking the materials inside the first mounting frame and the second mounting frame.

[0012] Preferably, the outer surfaces of the first mounting frame and the second mounting frame are each fixedly connected with a plurality of second hinges, and the outer surface of each second hinge is fixedly connected to the corresponding door. The outer surface of the second mounting frame is fixedly connected with a handle.

[0013] By adopting the above technical solution, the second hinge allows the frame door to rotate around the corresponding second hinge, making it easy to open and close the frame door. The handle adopts a cylindrical or arc-shaped structure, and the surface may be treated with anti-slip treatment. The installation position must conform to ergonomics. The operator can easily lift or push the second mounting frame by holding the handle.

[0014] Preferably, the outer surfaces of the two door frames are fixedly connected to connecting columns, the inner walls of each connecting column are fixedly connected to a first spring, and one end of each first spring is fixedly connected to a push plate.

[0015] By adopting the above technical solution, the connecting column, the first spring, and the push plate are design supplements for the locking and unlocking functions of the frame door. They are used to ensure the stable fixation of the frame door in the closed state and prevent the frame door from being accidentally opened due to bumps during transportation. The connecting column serves as the mounting carrier for the first spring and the push plate, providing installation space and guidance. The first spring provides elastic thrust, pushing the push plate outward to provide power for the locking structure. The push plate transmits the elastic force of the first spring, and the locking or unlocking of the frame door is achieved through cooperation with the external structure.

[0016] Preferably, each push plate has a connecting rod fixedly connected to the end away from the corresponding first spring, and the outer surface of each connecting rod and push plate is slidably connected to the corresponding connecting post.

[0017] By adopting the above technical solution, by pushing the push plate, the push plate will drive the corresponding connecting rod to slide horizontally along the corresponding connecting column. During this process, the first spring will be compressed, and the connecting rod will have a horizontal outward potential energy.

[0018] Preferably, the outer surfaces of the other two frame doors are fixedly connected with locking blocks, and the outer surface of each connecting rod is inserted into the corresponding locking block.

[0019] By adopting the above technical solution, the card block provides a slot structure, which is engaged with the corresponding connecting rod to achieve mutual locking of the double doors. The connecting rod acts as a pin, and the two doors are closed and fixed by inserting into the corresponding card block. The operator presses the end of the connecting rod of the left door to compress the first spring, which drives the connecting rod to be pulled out from the card block of the right door. After the engagement is released, the left and right doors can be opened by rotating around their respective second hinges, which is convenient for loading and unloading materials.

[0020] Preferably, a plurality of casters are fixedly mounted on the bottom surface of the first mounting bracket, and a locking block is fixedly connected to the outer surface of each caster.

[0021] By adopting the above technical solution, the casters are fixedly installed on the bottom surface of the first mounting frame to enable the flexible movement of the transport vehicle and adapt to different transport paths. The locking block is fixedly connected to the outer surface of each caster and has the function of locking the rotation of the casters, so that the transport vehicle remains stationary when parking or loading and unloading materials.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This material transport vehicle comprises a first mounting frame, a second mounting frame, a first hinge, insertion holes, a second spring, a connecting plate, an insertion rod, and a push block. By pushing the push block, the corresponding connecting plate and insertion rod slide vertically upward along the second mounting frame. During this process, the insertion rod slides out from the corresponding insertion hole. At this time, by rotating the second mounting frame, it rotates around the first hinge, thereby opening the second mounting frame to facilitate inspection of the material inside the first mounting frame at the bottom. Thus, this device achieves the effect of loading, unloading, and arranging heavier materials at the bottom by opening and closing the second mounting frame. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A material transport vehicle, referring to Figure 1 , Figure 3 , Figure 5The system includes a first mounting frame 1, with a first hinge 3 fixedly connected to its outer surface. A second mounting frame 2 is located above the first mounting frame 1, with its outer surface fixedly connected to the first hinge 3. Two insertion holes 15 are formed on the upper surface of the first mounting frame 1. Two second springs 21 are fixedly connected to the inner wall of the second mounting frame 2. A connecting plate 18 is fixedly connected to the bottom end of each second spring 21. A plug rod 20 is fixedly connected to the bottom surface of each connecting plate 18. Each plug rod 20 and the outer surface of the connecting plate 18 are slidably connected to the second mounting frame 2. The outer surface of each plug rod 20 is inserted into the corresponding insertion hole 15. A push block 19 is fixedly connected to the outer surface of each connecting plate 18. The first mounting frame 1 serves as a basic load-bearing component, with two insertion holes 15 for mounting. The first mounting bracket 1 is located above the first mounting bracket 1 and is connected to the first mounting bracket 1 via the first hinge 3. The second mounting bracket 2 can rotate around the first hinge 3, which facilitates the inspection of the material inside the first mounting bracket 1 when there is no material in the second mounting bracket 2. By pushing the push block 19, the push block 19 will drive the corresponding connecting plate 18 to squeeze the corresponding second spring 21, and the plug rod 20 will move out of the corresponding insertion hole 15. Similarly, when fixing the two, the first mounting bracket 1 will squeeze the plug rod 20 to slide into the second mounting bracket 2 until the plug rod 20 and the corresponding insertion hole 15 are on the same central axis. Then, the second spring 21 will push the corresponding plug rod 20 into the insertion hole 15 under its rebound force.

[0027] Example 2: A material transport vehicle, please refer to... Figure 5 The outer surface of the second mounting bracket 2 is fixedly connected with several elastic locking plates 17. The outer surface of each elastic locking plate 17 is engaged with the corresponding connecting plate 18. During the process of pushing the connecting plate 18, the connecting plate 18 can be fixed by the engagement between the elastic locking plate 17 and the corresponding connecting plate 18. The operator pushes the push block 19 upward, causing the connecting plate 18 and the insertion rod 20 to rise until the insertion rod 20 is completely disengaged from the insertion hole 15. When the connecting plate 18 rises to a specific height, the elastic locking plate 17 automatically engages with the corresponding position of the connecting plate 18 due to its own elastic deformation, hooking and fixing the connecting plate 18. When the second mounting bracket 2 is rotated to the target position, the operator only needs to push the elastic locking plate 17 upward or outward with a little force to unlock the fixing of the connecting plate 18.

[0028] Please see Figure 1 , Figure 2 , Figure 3The inner walls of the first mounting frame 1 and the second mounting frame 2 are both fixedly connected with baffles 5. The interior of the first mounting frame 1 and the second mounting frame 2 is provided with two frame doors 8. The inner wall of each frame door 8 is fixedly connected with a mounting rod 9. The baffles 5 are evenly arranged around the first mounting frame 1 and the second mounting frame 2. The baffles 5 and the mounting rods 9 are used to close the first mounting frame 1 and the second mounting frame 2, which helps to block the materials inside the first mounting frame 1 and the second mounting frame 2.

[0029] Please see Figure 2 The outer surfaces of the first mounting bracket 1 and the second mounting bracket 2 are fixedly connected with a number of second hinges 16. The outer surface of each second hinge 16 is fixedly connected to the corresponding door 8. The outer surface of the second mounting bracket 2 is fixedly connected with a handle 4. The second hinges 16 allow the door 8 to rotate around the corresponding second hinge 16, making it easy to open and close the door 8. The handle 4 has a cylindrical or arc-shaped structure, and the surface may be treated with anti-slip treatment. The installation position must conform to ergonomics. The operator can easily lift or push the second mounting bracket 2 by holding the handle 4.

[0030] Please see Figure 1 , Figure 3 The outer surfaces of the two door frames 8 are fixedly connected to connecting posts 11. The inner wall of each connecting post 11 is fixedly connected to a first spring 12. One end of each first spring 12 is fixedly connected to a push plate 13. The connecting posts 11, the first springs 12, and the push plates 13 are supplementary designs for the locking and unlocking functions of the door frames 8. They are used to ensure the stable fixation of the door frames 8 in the closed state and to prevent the door frames 8 from being accidentally opened due to bumps during transportation. The connecting posts 11 serve as the mounting carrier for the first springs 12 and the push plates 13, providing installation space and guidance. The first springs 12 provide elastic thrust, pushing the push plates 13 outward to provide power for the locking structure. The push plates 13 transmit the elastic force of the first springs 12, and the door frames 8 are locked or unlocked by cooperating with the external structure.

[0031] Please see Figure 3 Each push plate 13 is fixedly connected to a connecting rod 14 at the end away from the corresponding first spring 12. The outer surface of each connecting rod 14 and the push plate 13 is slidably connected to the corresponding connecting post 11. By pushing the push plate 13, the push plate 13 will drive the corresponding connecting rod 14 to slide horizontally along the corresponding connecting post 11. During this process, the first spring 12 will be compressed. During this process, the connecting rod 14 has a horizontal outward potential energy.

[0032] Please see Figure 1 , Figure 3The outer surfaces of the other two door frames 8 are fixedly connected with locking blocks 10. The outer surface of each connecting rod 14 is inserted into the corresponding locking block 10. The locking block 10 provides a slot structure and engages with the corresponding connecting rod 14 to achieve mutual locking of the double doors. The connecting rod 14 acts as a pin and completes the closing and fixing of the two door frames 8 by inserting into the corresponding locking block 10. When the operator presses the end of the connecting rod 14 of the left door, the first spring 12 is compressed, which drives the connecting rod 14 to be pulled out from the locking block 10 of the right door. After the insertion relationship is released, the left and right door frames 8 can be rotated and opened around their respective second hinges 16 to facilitate the loading and unloading of materials.

[0033] Please see Figure 4 Several casters 6 are fixedly installed on the bottom surface of the first mounting frame 1. Each caster 6 has a locking block 7 fixedly connected to its outer surface. The casters 6 are fixedly installed on the bottom surface of the first mounting frame 1 to enable the flexible movement of the transport vehicle and adapt to different transport paths. The locking block 7 is fixedly connected to the outer surface of each caster 6 and has the function of locking the rotation of the caster 6, so that the transport vehicle remains stationary when parking or loading and unloading materials.

[0034] The implementation principle of this application embodiment is as follows: First, hold the handle 4 and push the first mounting bracket 1 and the second mounting bracket 2 to the designated position. Then, fix the transport vehicle by controlling the locking block 7. At this time, by pushing the push plate 13, the push plate 13 will drive the corresponding connecting rod 14 to move out of the corresponding locking block 10, and the first spring 12 will be compressed. At this time, the first mounting bracket 1 and the second mounting bracket 2 can be opened by pulling the frame door 8. Then, push the push block 19 to drive the corresponding connecting plate 18 and the insertion rod 20 to slide vertically upward along the second mounting bracket 2. During this process, the insertion rod 20 slides out from the corresponding insertion hole 15. Until the elastic plate 17 is engaged and fixed with the corresponding connecting plate 18, the second mounting frame 2 can be opened by rotating it around the first hinge 3. Then, heavy materials can be placed in the first mounting frame 1 to lower the center of gravity. Then, the second mounting frame 2 is rotated in the opposite direction until the insertion hole 15 and the corresponding insertion rod 20 are on the same central axis. By moving the elastic plate 17, the second spring 21 will push the corresponding insertion rod 20 into the corresponding insertion hole 15 under its rebound force. Then, light materials can be placed in the second mounting frame 2 to increase the stability of the transport vehicle.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
