Description

Technical Field

[0001] This utility model relates to the field of luggage trolleys, and more specifically, to a deformable luggage trolley. Background Technology

[0002] The main function of airport baggage trolleys is to help passengers carry and transport their luggage, reducing their burden and improving the efficiency of baggage handling at airports. For example, a stable advertising board structure for an airport trolley, as disclosed in application number 202420312706.0, features two symmetrically arranged trolley supports and two support beams spaced apart between them. The support beams are detachably connected to the trolley supports. This structure facilitates the application of advertising materials and reduces labor costs. However, this type of airport baggage trolley lacks a folding and deforming function, resulting in a large size that is inconvenient for placement and storage, thus reducing the effectiveness of the equipment.

[0003] Therefore, this application proposes a deformable luggage trolley. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a deformable luggage trolley, employing the following technical solution:

[0005] A deformable luggage trolley includes a placement board, with drive wheels on the triangular bottom of the placement board, two symmetrically distributed auxiliary frames on the top of the placement board, and a back panel on the top of the placement board.

[0006] The back panel includes two first support rods located on top of the placement plate, and a second support rod above each of the two first support rods. The bottom ends of the two second support rods have storage slots that match the first support rods on the same side. A second plate is fixedly installed between the two second support rods. The bottom end of the second plate has a groove, and a first plate is slidably installed in the groove. The lower sections of the first plate are fixedly connected to the side walls of the first support rods on the same side. A connecting block is fixedly installed between the top ends of the two second support rods. Two symmetrically distributed handles are provided on one side of the connecting block. Support columns are fixedly installed on the side walls of the two second support rods. A fixing component is provided between the two support columns and the second support rods. A folding component is provided between the two first support rods and the placement plate.

[0007] By adopting the above technical solution, the placement plate of the device is inclined, which helps to reduce the possibility of luggage slipping off the front of the placement plate during travel. The back plate is composed of a first support rod, a first plate, a second support rod, a second plate, and a connecting block. The second support rod and the first support rod on the same side are slidably connected, and the second plate is slidably fitted onto the side wall of the first plate, which makes it easy for users to adjust the height of the back plate, so that the device can hold different numbers of luggage, which helps to improve the use of the device. A fixing component is provided between the first support rod and the second support rod to fix the second support rod, which helps to maintain the stability of the back plate. A folding component is provided between the back plate and the placement plate, so that the back plate can be folded up to fit snugly against the top of the placement plate, which facilitates subsequent storage and helps to reduce the placement space of the device. An auxiliary frame is provided on the top of the placement plate, which can adjust the placement area of ​​the top of the placement plate, so that the device can hold luggage of different sizes, which helps to improve the use of the device.

[0008] As a further optimization, the fixing component includes a tie rod disposed on the side of the two pillars away from the second support rod on the same side. Each of the two pillars has a movable groove, and each of the two movable grooves has a mounting plate slidably installed in it. Each of the two mounting plates has a fixing block fixedly installed on the side away from the tie rod. The two fixing blocks slide through the pillars on the same side and extend into the grooves on the same side. Each of the two first support rods has a plurality of fixing grooves on its sidewall that match the fixing blocks on the same side. Each of the two mounting plates has a stabilizing rod fixedly installed on the side away from the fixing blocks on the same side. Each of the two stabilizing rods has a spring sleeved on its sidewall. Each of the two stabilizing rods has an end that passes through the pillars on the same side away from the fixing blocks on the same side and is fixedly connected to the side opposite to the tie rod. Each of the two fixing blocks has a chamfered top at the end away from the tie rod. Each of the inner walls at the top of the fixing groove has an inclined angle.

[0009] By adopting the above technical solution, when it is necessary to increase the height between the first and second support rods, the user only needs to hold the first support rod and then pull the second support rod through the connecting block. Because the side wall of the fixing block has a chamfer and the inner wall of the top of the fixing groove has an inclined angle, the fixing block slides into the movable groove on the same side under the action of the lifting force, thereby disengaging the fixing block from the fixing groove on the same side, which can adjust the distance between the second and first support rods. When it is necessary to lower the height of the back panel, the user pulls the stabilizing rod through the pull rod. The stabilizing rod slides with the mounting plate on the same side, and the mounting plate compresses the spring on the same side, causing the mounting plate to slide into the movable groove on the same side, disengaging the fixing block from the fixing groove, which can push the second support rod downward to lower the height of the back panel. Then, the pull rod is released, and the fixing block returns to its original position under the elastic force of the spring on the same side, engaging the corresponding fixing groove, which can fix the second support rod for subsequent use.

[0010] As a further optimization, the folding assembly includes inserts at the bottom of the two first support rods, and a slot matching the insert is provided at the top of the placement plate. The insert includes a second support block that is slidably installed in the slot. The top of each of the two second support blocks is hinged to a first support block, and the top of each of the two first support blocks is fixedly connected to the bottom of the first support rod on the same side.

[0011] By adopting the above technical solution, when it is necessary to bend the back panel, the first support rod is lifted, and the first support rod moves the insert block on the same side out of the slot on the same side. The insert block is composed of the first support block and the second support block hinged together. After the insert block is moved out of the slot, the back panel is flipped, so that the back panel and the first support block are flipped, and then the back panel is flipped to the top of the placement plate, which can fold and store the equipment, and helps to reduce the placement space of the equipment.

[0012] As a further optimization, both slots have grooves on their sidewalls, and sliders are slidably installed in both grooves. The two sliders are fixedly connected to the opposite side of the second support block on the same side.

[0013] By adopting the above technical solution, when the second support block slides in the slot on the same side, the second support block slides in the groove on the same side along with the slider. Through the cooperation of the slider and the groove, the positioning block is restricted, which helps to prevent the block from falling out of the slot.

[0014] As a further optimization, the auxiliary frame includes two sets of support blocks that are slidably installed on the top of the placement plate. There are three support blocks in the same set, which are arranged in a straight array on the top of the placement plate. The top of the placement plate has a moving groove that matches the support blocks. Each moving groove has a baffle fixedly installed in it. An assembly plate is fixedly installed between the ends of the three support blocks on the same side away from the placement plate.

[0015] By adopting the above technical solution, an auxiliary frame is provided on the top of the placement board. The auxiliary frame consists of multiple support blocks and assembly plates. When the top area of ​​the placement board is insufficient, the user can pull the support block on the same side through the assembly plate and slide it in the moving groove on the same side. This adjusts the distance between the assembly plate and the placement board, thereby adjusting the top area of ​​the placement board. This allows the equipment to accommodate luggage of different sizes and improves the efficiency of the equipment.

[0016] As a further optimization, limit plates are fixedly installed on the top of the support block at the end away from the same side assembly plate.

[0017] By adopting the above technical solution, a limiting plate is provided on the top of the support block, and a baffle is provided in the moving groove. The combination of the limiting plate and the baffle plays a role in restricting and positioning the support block, which helps to prevent the support block from leaving the moving groove.

[0018] This utility model has the following beneficial technical effects:

[0019] 1. The distance between the first and second plates in the back panel is adjustable, which makes it easy to stack different numbers of luggage. A folding component is provided between the back panel and the placement board, which makes it easy to bend the back panel and place it on top of the placement board, which helps to reduce the placement space of the equipment and improve the use of the equipment.

[0020] 2. Two symmetrically distributed auxiliary frames are provided on the top of the placement board. The auxiliary frames can slide on the top of the placement board to increase the area of ​​the placement board, making it easier to place luggage of different sizes and improving the efficiency of the equipment.

[0033] Please see Figures 1 to 7 As shown, a deformable luggage trolley includes a placement plate 2. Each of the triangular bottom ends of the placement plate 2 is equipped with a drive wheel 1. The top of the placement plate 2 is equipped with two symmetrically distributed auxiliary frames 3. The top of the placement plate 2 is equipped with a back plate 4. Each auxiliary frame 3 includes two sets of support blocks 31 that are slidably installed on the top of the placement plate 2. There are three support blocks 31 in the same set, which are arranged in a straight array on the top of the placement plate 2. The top of the placement plate 2 is provided with a moving groove 21 that matches the support blocks 31. Each moving groove 21 is fixedly installed with a baffle 22. An assembly plate 32 is fixedly installed between the ends of the three support blocks 31 on the same side away from the placement plate 2. Each end of the support block 31 away from the assembly plate 32 on the same side is fixedly installed with a limit plate 311.

[0034] The placement plate 2 of the device is inclined, which helps reduce the possibility of luggage slipping off the front of the placement plate 2 during travel. The back plate 4 is composed of a first support rod 41, a first plate 42, a second support rod 43, a second plate 44, and a connecting block 45. The second support rod 43 is slidably connected to the first support rod 41 on the same side, and the second plate 44 is slidably sleeved on the side wall of the first plate 42. This allows the user to adjust the height of the back plate 4, so that the device can hold different numbers of luggage, which helps to improve the usability of the device. An auxiliary frame 3 is provided on the top of the placement plate 2. The auxiliary frame 3 is composed of multiple support blocks 31 and an assembly. The device consists of a plate 32. When the top area of ​​the placement plate 2 is insufficient, the user can pull the assembly plate 32 to slide the support block 31 on the same side into the moving groove 21 on the same side. This adjusts the distance between the assembly plate 32 and the placement plate 2, thereby adjusting the top area of ​​the placement plate 2. This allows the device to accommodate luggage of different sizes, improving the efficiency of the device. The support block 31 has a limiting plate 311 on top, and the moving groove 21 has a baffle 22. The combination of the limiting plate 311 and the baffle 22 restricts and positions the support block 31, helping to prevent the support block 31 from detaching from the moving groove 21.

[0035] The back panel 4 includes two first support rods 41 disposed on the top of the placement plate 2. A second support rod 43 is disposed above each of the two first support rods 41. The bottom ends of the two second support rods 43 have storage slots 432 that match the first support rods 41 on the same side. A second plate 44 is fixedly installed between the two second support rods 43. A groove is formed at the bottom end of the second plate 44, within which the first plate 42 is slidably installed. The lower sections of the first plate 42 are fixedly connected to the side walls of the first support rods 41 on the same side. A connecting block 45 is fixedly installed between the top ends of the two second support rods 43. Two symmetrically distributed handles are provided on one side of the connecting block 45. Support columns 431 are fixedly installed on the side walls of both second support rods 43. A fixing assembly is provided between the two support columns 431 and the second support rods 43. The fixing assembly includes components disposed on the two support columns 431 away from the same side. The second support rod 43 has a tie rod 5 on one side. Both support columns 431 have movable grooves 7. Both movable grooves 7 have mounting plates 73 that are slidably installed in them. Both mounting plates 73 have fixing blocks 74 fixedly installed on the side away from the tie rod 5. Both fixing blocks 74 slide through the support column 431 on the same side and extend into the groove on the same side. The side walls of the two first support rods 41 have multiple fixing grooves that match the fixing blocks 74 on the same side. Both mounting plates 73 have stabilizing rods 72 fixedly installed on the side away from the fixing blocks 74 on the same side. Both stabilizing rods 72 have springs 71 sleeved on their side walls. The ends of the two stabilizing rods 72 that are away from the fixing blocks 74 on the same side pass through the support column 431 on the same side and are fixedly connected to the side opposite to the tie rod 5. The top of the ends of the two fixing blocks 74 that are away from the tie rod 5 have chamfers. The inner walls of the top of the fixing grooves have inclination angles.

[0036] When it is necessary to increase the height between the first support rod 41 and the second support rod 43, the user only needs to hold down the first support rod 41 and then pull the second support rod 43 through the connecting block 45. Because the side wall of the fixing block 74 has a chamfer and the inner wall of the top of the fixing groove has an inclined angle, the fixing block 74 slides into the movable groove 7 on the same side under the action of the lifting force, thereby disengaging the fixing block 74 from the fixing groove on the same side, which can adjust the distance between the second support rod 43 and the first support rod 41. And when it is necessary to lower the height of the back plate 4, the user can... Pulling the stabilizing rod 72 via the pull rod 5 causes the stabilizing rod 72 to slide along the mounting plate 73 on the same side. The mounting plate 73 compresses the spring 71 on the same side, causing the mounting plate 73 to slide along the fixing block 74 on the same side into the movable groove 7 on the same side. This causes the fixing block 74 to disengage from the fixing groove, which in turn pushes the second support rod 43 downward, thus reducing the height of the back plate 4. After releasing the pull rod 5, the fixing block 74 returns to its original position under the elastic force of the spring 71 on the same side, and the corresponding fixing groove engages, thus fixing the second support rod 43 for subsequent use.

[0037] A folding assembly is provided between the two first support rods 41 and the placement plate 2. The folding assembly includes an insert 6 at the bottom of the two first support rods 41. The top of the placement plate 2 has a slot 23 that matches the insert 6. The insert 6 includes a second support block 62 that is slidably installed in the slot 23. The top of each of the two second support blocks 62 is hinged to a first support block 61. The top of each of the two first support blocks 61 is fixedly connected to the bottom of the first support rod 41 on the same side. When the back plate 4 needs to be bent, the first support rod 41 is lifted, and the first support rod 41 moves the insert 6 on the same side out of the slot 23 on the same side. The insert 6 is composed of the first support block 61 and the second support block 62 hinged together. After the insert 6 is moved out of the slot 23, the back plate 4 is flipped, causing the back plate 4 to flip with the first support block 61, and then the back plate 4 is flipped to the top of the placement plate 2, thus folding and storing the equipment, which helps to reduce the placement space of the equipment.

[0038] Both slots 23 have grooves 231 on their side walls, and sliders are slidably installed in both grooves 231. The two sliders are fixedly connected to the opposite side of the second support block 62 on the same side. When the second support block 62 slides in the slot 23 on the same side, the second support block 62 slides in the groove 231 on the same side along with the sliders. Through the cooperation of the sliders and the grooves 231, the positioning block 6 is restricted, which helps to prevent the block 6 from falling out of the slot 23.
