Description

Technical Field

[0001] The utility model belongs to the technical field of building decoration, and particularly relates to a portable carrying rack for building decoration. Background Art

[0002] Building decoration refers to the process of beautifying, transforming and optimizing the internal and external spaces of a building after the basic structure of the building is completed, aiming to improve the functionality and artistry of the building, and create a more comfortable, beautiful and practical living or working environment. Building decoration covers many aspects, including but not limited to the decoration treatment of walls, floors and ceilings, the selection and installation of doors, windows, lamps and furniture, as well as the layout and color matching of interior spaces.

[0003] During actual construction and decoration, there is a lack of a portable carrying rack that can efficiently and safely carry objects of different sizes. The problems existing in the above technology are as follows: In building decoration projects, it is often necessary to carry various sizes and weights of materials and equipment. Traditional carrying methods usually rely on manual carrying or simple handcarts. These methods are not only inefficient and labor-intensive, but also easily cause damage to objects during the carrying process, affecting the project quality. Especially in narrow spaces or high-rise buildings, the limitations of traditional carrying methods are more obvious and it is difficult to meet the requirements of efficient construction. Secondly, the construction site of building decoration is often complex in environment and the ground conditions are changeable. The flexibility and adaptability of traditional carrying tools are insufficient to cope with complex terrains and narrow passages. This not only increases the difficulty of carrying, but also may bring potential safety hazards and affect the safety of construction workers. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a portable carrying rack for building decoration that can overcome or at least partially solve the above problems.

[0005] The utility model is realized as follows: A portable carrying rack for building decoration includes a handle, a load-carrying plate and universal wheels. The lower end of the handle is fixedly connected to the inner wall of the front end of the load-carrying plate. The lower end of the load-carrying plate is fixedly connected to the surface of the universal wheels. A limiting device is arranged on the surface of the load-carrying plate, and an auxiliary mechanism is arranged inside the load-carrying plate;

[0006] The limiting device is used for fixing the goods;

[0007] The auxiliary mechanism is used for expanding the load-carrying area.

[0008] To improve the adaptability of the device, preferably, the limiting device includes a driving motor, a driving screw, a driven gear, a connecting rod, a mating gear, an adjusting rack, a connecting block and a limiting plate. The output end of the driving motor is fixedly connected to the surface of the driving screw. The surface of the driving screw is meshed with the surface of the driven gear. The inner wall of the driven gear is fixedly connected to the lower end of the connecting rod. The upper end of the connecting rod is fixedly connected to the inner wall of the mating gear. The surface of the mating gear is meshed with the surfaces of the two adjusting racks. The rear end of the adjusting rack is fixedly connected to the inner wall of the connecting block. The upper surface of the connecting block is fixedly connected to the lower surface of the limiting plate. The meshing between the mating gear and the two adjusting racks not only enables flexible adjustment of the position of the limiting plate, but also ensures the smoothness and reliability of the adjustment process, enabling it to closely fit objects of different sizes and shapes, effectively avoiding shaking or displacement of the objects during transportation, and greatly improving the safety and efficiency of transportation.

[0009] To increase the load-bearing area of the device, preferably, the auxiliary mechanism includes an auxiliary block, an auxiliary screw, a support block and an extension plate. One end of the auxiliary screw is fixedly connected to the inner wall of the auxiliary block. The surface of the auxiliary screw is threadedly connected to the inner walls of the two support blocks. The surface of the support block is fixedly connected to one side surface of the extension plate. The two ends of the auxiliary screw have different thread directions, ensuring that when the auxiliary screw rotates, the two support blocks can move in opposite directions, enabling the extension plates on both sides to smoothly extend out from inside the load-bearing plate under the push of the support blocks, thereby effectively increasing the usable area of the load-bearing plate and meeting the transportation requirements for more or larger-sized objects.

[0010] To improve the safety of transportation, preferably, a protective box is provided on one side of the load-bearing plate. The surface of the protective box is fixedly connected to the surface of the load-bearing plate. Two baffle plates are provided on both sides of the load-bearing plate. The upper ends of the baffle plates are rotatably connected to the upper side surface of the load-bearing plate through a rotating shaft. When it is necessary to expand the area of the load-bearing plate, the baffle plates can be unfolded as the extension plates extend, ensuring that the boundary of the expanded load-bearing area is clear, avoiding accidental dropping of objects during transportation, and improving the safety of transportation. At the same time, when the area does not need to be expanded or after the transportation task is completed, the baffle plates can be easily folded back to their original positions, without occupying extra space, facilitating the storage and handling of the handling rack.

[0011] To improve the smoothness of operation, preferably, the surface of the driving motor is fixedly connected to the lower end of the load-carrying plate, the surface of the driven gear is rotatably connected to the lower surface of the load-carrying plate, the surface of the connecting rod is rotatably connected to the inner wall of the load-carrying plate, the surface of the mating gear is rotatably connected to the upper inner wall of the load-carrying plate, the surfaces of the two adjusting racks are slidably connected to the upper inner wall of the load-carrying plate through sliding grooves, the surfaces of the two connecting blocks are slidably connected to the upper inner wall of the load-carrying plate, and the lower surfaces of the two limiting plates are slidably connected to the upper surface of the load-carrying plate. The rotational connection between the driven gear and the lower surface of the load-carrying plate ensures the smoothness and stability of the driven gear during rotation, reduces friction and wear, and improves the transmission efficiency. The sliding connection between the adjusting rack and the upper inner wall of the load-carrying plate through the sliding groove enables the adjusting rack to slide freely in the horizontal direction, realizing the flexible adjustment of the position of the limiting plate.

[0012] To improve the stability of the device, preferably, the surfaces of the two support blocks are slidably connected to one inner wall of the load-carrying plate, and the surfaces of the two extension plates are slidably connected to the inner wall of the load-carrying plate. The sliding connection between the support block and one inner wall of the load-carrying plate reduces friction and wear and improves the durability of the device. The sliding connection between the extension plate and the inner wall of the load-carrying plate enables the extension plate to freely expand and contract in the horizontal direction, realizing the flexible expansion of the area of the load-carrying plate to adapt to the transportation requirements of objects of different sizes and quantities.

[0013] To improve the reliability of the equipment, preferably, the inner wall of the protective box is rotatably connected to the two end surfaces of the auxiliary screw, and the surface of the baffle is slidably connected to the surface of the extension plate. The sliding connection between the baffle and the surface of the extension plate enables the baffle to slide freely when the extension plate extends and retracts, ensuring the stability and reliability of the baffle at different positions of the extension plate.

[0014] The utility model fixes goods by setting a limiting device, an auxiliary mechanism, a driving screw, a driven gear, a connecting rod, a mating gear, an adjusting rack, an auxiliary block, an auxiliary screw, a supporting block and an extension plate. The limiting device is used for fixing goods, and the auxiliary mechanism is used for expanding the carrying area. The engagement between the mating gear and the two adjusting racks not only realizes the flexible adjustment of the position of the limiting plate, but also ensures the smoothness and reliability of the adjustment process, enabling it to closely fit when facing objects of different sizes and shapes, effectively avoiding the shaking or displacement of objects during transportation, and greatly improving the safety and efficiency of transportation. The two ends of the auxiliary screw have different thread directions, ensuring that when the auxiliary screw rotates, the two supporting blocks can move in opposite directions, so that the extension plates on both sides can smoothly extend outwards from the inside of the carrying plate under the push of the supporting blocks, effectively increasing the use area of the carrying plate and meeting the transportation needs of more or larger-sized objects. This solves the problems in building decoration projects where various sizes and weights of materials and equipment often need to be transported. Traditional handling methods usually rely on manual handling or simple handcarts. These methods are not only inefficient and labor-intensive, but also easily cause damage to objects during handling, affecting the project quality. Especially in narrow spaces or high-rise buildings, the limitations of traditional handling methods are more obvious and difficult to meet the requirements of efficient construction. Secondly, the construction site of building decoration is often complex in environment and variable in ground conditions. The flexibility and adaptability of traditional handling tools are insufficient to cope with complex terrains and narrow passages, which not only increases the handling difficulty, but also may bring potential safety hazards and affect the safety of construction workers.

[0021] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 4As shown in the figure, the portable handling rack for building decoration provided by the embodiment of the present utility model includes a handle 5, a load-carrying plate 6, and universal wheels 7. The lower end of the handle 5 is fixedly connected to the inner wall of the front end of the load-carrying plate 6, and the lower end of the load-carrying plate 6 is fixedly connected to the surface of the universal wheels 7.

The limiting device 1 includes a driving motor 101, a driving screw 102, a driven gear 103, a connecting rod 104, a mating gear 105, an adjusting rack 106, a connecting block 107, and a limiting plate 108. The output end of the driving motor 101 is fixedly connected to the surface of the driving screw 102. The surface of the driving screw 102 is meshed with the surface of the driven gear 103.

The rear end of the adjusting rack 106 is fixedly connected to the inner wall of the connecting block 107. The upper surface of the connecting block 107 is fixedly connected to the lower surface of the limiting plate 108. The meshing between the mating gear 105 and the two adjusting racks 106 not only realizes the flexible adjustment of the position of the limiting plate 108 but also ensures the smoothness and reliability of the adjustment process, enabling it to closely fit when facing objects of different sizes and shapes, effectively avoiding the phenomenon of shaking or displacement of the objects during transportation, and greatly improving the safety and efficiency of transportation. The auxiliary mechanism 2 includes an auxiliary block 201, an auxiliary screw 202, a support block 203, and an extension plate 204. The inner wall of the auxiliary block 201 is fixedly connected to one end of the auxiliary screw 202. The surface of the auxiliary screw 202 is threadedly connected to the inner walls of two support blocks 203. The surface of the support block 203 is fixedly connected to one side surface of the extension plate 204. The two ends of the auxiliary screw 202 have different thread directions, ensuring that when the auxiliary screw 202 rotates, the two support blocks 203 can move in opposite directions, so that the extension plates 204 on both sides can smoothly extend out from the inside of the load-carrying plate 6 under the push of the support blocks 203, thus effectively increasing the usable area of the load-carrying plate 6 and being able to meet the transportation requirements of more or larger-sized objects. A protective box 3 is arranged on one side of the load-carrying plate 6. The surface of the protective box 3 is fixedly connected to the surface of the load-carrying plate 6. Two baffle plates 4 are arranged on both sides of the load-carrying plate 6. The upper ends of the baffle plates 4 are rotatably connected to the upper side surface of the load-carrying plate 6 through a rotating shaft. When it is necessary to expand the area of the load-carrying plate 6, the baffle plates 4 can be unfolded as the extension plates 204 extend out, ensuring that the boundary of the expanded load-carrying area is clear and avoiding the accidental dropping of objects during transportation, improving the safety of transportation. At the same time, when the area does not need to be expanded or after the transportation task is completed, the baffle plates 4 can be easily folded back to their original positions without occupying extra space, facilitating the storage and handling of the handling rack. The surface of the driving motor 101 is fixedly connected to the lower end of the load-carrying plate 6. The surface of the driven gear 103 is rotatably connected to the lower surface of the load-carrying plate 6. The surface of the connecting rod 104 is rotatably connected to the inner wall of the load-carrying plate 6.The surface of the mating gear 105 is rotatably connected to the upper inner wall of the load plate 6. The surfaces of the two adjusting racks 106 are slidably connected to the upper inner wall of the load plate 6 through sliding grooves. The surfaces of the two connecting blocks 107 are slidably connected to the upper inner wall of the load plate 6. The lower surfaces of the two limiting plates 108 are slidably connected to the upper surface of the load plate 6. The driving gear 103 is rotatably connected to the lower surface of the load plate 6, ensuring the smoothness and stability of the driving gear 103 during rotation, reducing friction and wear, and improving the transmission efficiency. The adjusting rack 106 is slidably connected to the upper inner wall of the load plate 6 through a sliding groove, enabling the adjusting rack 106 to slide freely in the horizontal direction and realizing the flexible adjustment of the position of the limiting plate 108. The surfaces of the two support blocks 203 are slidably connected to the inner wall of one side of the load plate 6. The surfaces of the two extension plates 204 are slidably connected to the inner wall of the load plate 6. The sliding connection between the support block 203 and the inner wall of one side of the load plate 6 reduces friction and wear and improves the durability of the device. The sliding connection between the extension plate 204 and the inner wall of the load plate 6 enables the extension plate 204 to expand and contract freely in the horizontal direction, realizing the flexible expansion of the area of the load plate 6 to adapt to the transportation requirements of objects of different sizes and quantities. The inner wall of the protective box 3 is rotatably connected to the surfaces of both ends of the auxiliary screw 202. The surface of the baffle 4 is slidably connected to the surface of the extension plate 204. The sliding connection between the baffle 4 and the surface of the extension plate 204 enables the baffle 4 to slide freely when the extension plate 204 extends and retracts, ensuring the stability and reliability of the baffle 4 at different positions of the extension plate 204.,

[0023] During the process of transporting objects, first, the objects to be transported need to be placed steadily on the loading plate 6. Subsequently, according to the actual size and shape of the objects, the limiting device 1 on the loading plate 6 is adjusted to ensure that the objects can be firmly fixed. This process starts by activating the drive motor 101 located at the bottom of the loading plate 6. When the drive motor 101 operates, its output shaft drives the active screw 102 to rotate. Since there is an engagement relationship between the active screw 102 and the driven gear 103, the driven gear 103 rotates accordingly and drives the upper mating gear 105 to rotate synchronously through the connecting rod 104. The mating gear 105 meshes with the two adjusting racks 106 on the inner wall of the loading plate 6, causing the adjusting racks 106 to move in a specific direction, and then driving the limiting plate 108 to move inwards or outwards until the limiting plate 108 closely adheres to the surface of the object, effectively preventing the object from shaking or shifting during transportation. In order to meet the transportation requirements of different quantities or larger-sized objects, this loading device also has an expansion function. Users can expand the area by manually rotating an auxiliary block 201 on the side of the loading plate 6. The rotation of the auxiliary block 201 causes the auxiliary screw 202 to rotate. The two ends of the auxiliary screw 202 have different thread directions, which means that during its rotation, the two support blocks 203 installed on it will move in opposite directions. This setting enables the expansion plates 204 on both sides to extend outwards from the inside of the loading plate 6 under the push of the support blocks 203, thereby expanding the effective area of the loading plate 6. As the expansion plates 204 extend out, the original baffles 4 on both sides of the loading plate 6 will also expand accordingly to ensure that the boundary of the expanded loading area is clear and provide guarantee for transportation safety. Once all the objects are properly placed and fixed, the user only needs to hold the handle 5 of the loading device to easily control the entire device to move, which not only improves the efficiency of single transportation but also greatly enhances the safety and reliability of the transportation process.
