Description

Technical Field

[0001] This utility model relates to the field of advertising design workbench technology, specifically a foldable and lightweight advertising design workbench frame structure. Background Technology

[0002] In the field of advertising design workbench technology, the design of the workbench frame directly affects the designer's work efficiency and portability. Existing advertising design workbenches mostly adopt fixed or simple folding structures, which, while meeting basic functions, have significant shortcomings.

[0003] Traditional workbench frames are mostly fixed structures, bulky and cannot be folded for storage, making them difficult to adapt to the needs of mobile design, outdoor exhibitions and other scenarios. Designers need to repeatedly disassemble and assemble them when moving between locations, which is inefficient and parts are easily lost. In addition, existing workbench angle adjustment mechanisms mostly rely on bolt locking, which is cumbersome to operate and cannot achieve multi-directional adjustment.

[0004] Therefore, a foldable and lightweight advertising design workbench frame structure is proposed to solve the above problems. Utility Model Content

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a foldable and lightweight advertising design workbench frame structure, which has the advantages of portability, quick storage, multi-angle adjustment and one-button locking. It solves the problems of traditional workbench frames being bulky and unable to be folded and stored efficiently, and angle adjustment mechanisms being cumbersome to operate and unable to achieve multi-directional adjustment and lacking portability.

[0006] (II) Technical Solution The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A foldable and retractable lightweight workbench frame structure for advertising design includes a columnar base. The bottom of the columnar base is provided with PVC suction cups arranged in a circular array. A ball joint extending upwards is movably connected inside the columnar base. The columnar base has a movable cavity that communicates with the bottom of the ball joint and extends to its left and right sides. The movable cavity has a locking component that abuts against the bottom of the ball joint and extends to the left and right sides of the columnar base. The opposite side of the locking component has the same dial ring located outside the columnar base. The top of the ball joint is fixedly connected with a guide groove. A fixed hinge shaft is fixedly connected at the center of the guide groove. A folding and retracting component adapted to the guide groove is provided outside the fixed hinge shaft. Rectangular storage tubes adapted to each other are provided on both the left and right sides of the folding and retracting component. A stop block is fixedly connected to the top of the front end of the rectangular storage tube. An elastic clamping component extending to its rear side and adapted to the stop block is provided inside the rectangular storage tube.

[0007] The beneficial effects of this utility model are: This foldable and lightweight advertising design workbench frame structure is fixed to a flat tabletop using PVC suction cups. The folding assembly is then unfolded, and the elastic clamping assembly is pulled out. The tablet or drawing board is placed on top of the rectangular storage tube, positioned between the stop block and the elastic clamping assembly. Releasing the elastic clamping assembly clamps the tablet or drawing board between the stop block and the elastic clamping assembly. Pressing down on the dial ring separates the locking assembly from the lower end of the ball joint, releasing the locking assembly's restriction on the ball joint. Moving the tablet or drawing board causes the ball joint to move within the columnar base until the tablet or drawing board is adjusted to the appropriate angle. Releasing the dial ring causes the locking assembly to automatically adhere to the lower end of the ball joint, thus limiting the adjusted tablet or drawing board. It boasts advantages such as portability, quick storage, multi-angle adjustment, and one-button locking.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the locking assembly includes a first spring, a contact block, and a horizontal plate. The bottom wall of the inner wall of the movable cavity is provided with a first spring. The top of the first spring is provided with a contact block that abuts against the bottom of the ball joint. The top of the contact block is provided with a rough friction surface. Horizontal plates extending through the movable cavity to the left and right sides of the columnar base are fixedly connected to both sides of the contact block. The opposite side of the horizontal plate is fixedly connected to the same pawl located outside the columnar base.

[0010] The beneficial effect of adopting the above-mentioned further solution is that pressing down the dial ring causes the contact block to move downward inside the movable cavity through the horizontal plate, so that the contact block separates from the bottom of the ball joint, thereby releasing the contact block from the ball joint. At the same time, the first spring is compressed to store energy. When the dial ring is released, the first spring recovers its deformation and releases energy, thereby pushing the contact block to automatically adhere to the lower end of the ball joint. The rough friction surface on the top of the contact block provides friction, ensuring that the ball joint does not slip or loosen after adjustment.

[0011] Furthermore, the folding assembly includes a free hinge shaft, cross links, and a connecting hinge shaft. The left and right sides of the fixed hinge shaft are provided with free hinge shafts that can move inside the guide groove. The outer sides of the fixed hinge shaft and the free hinge shaft are both fitted with cross links that are distributed vertically and alternately. A connecting hinge shaft is provided at the intersection of the two ends of adjacent cross links. Furthermore, the two unconnected parts of the cross link are provided with the same rectangular storage tube. The front cross link is hinged to the outer lug of the rectangular storage tube, and the rear cross link is movably connected to the outer lug of the rectangular storage tube through a strip hole.

[0012] The beneficial effect of adopting the above-mentioned further solution is that pulling the rectangular storage tube to the opposite side causes the cross link to unfold to the left and right sides of the fixed hinge axis. The free hinge axis moves along the guide groove to ensure the unfolding direction of the cross link and provide a dynamic support point. The connecting hinge axis ensures the flexible hinge between the cross links. The front cross link is hinged to the outer ear of the rectangular storage tube to provide a fixed fulcrum. The rear cross link is movably connected to the outer ear of the rectangular storage tube through the strip hole, allowing the cross link to slide and adjust to adapt to displacement during the folding process.

[0013] Furthermore, the elastic clamping assembly includes a hexagonal guide rod, a second spring, and a clamping plate. The interior of each rectangular storage tube is slidably connected with a hexagonal guide rod extending to its rear side. The outer side of each hexagonal guide rod is fitted with a second spring located inside the rectangular storage tube. The rear end of each hexagonal guide rod is fixedly connected with a clamping plate adapted to the stop block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by pulling out the hexagonal guide rod through the clamping plate, the second spring is compressed and stored. The digital tablet or drawing board is placed on top of the rectangular storage tube and between the stop block and the clamping plate. When the hexagonal guide rod is released, the second spring restores its deformation and releases energy. Then, the hexagonal guide rod drives the clamping plate to move towards the stop block, thereby clamping the digital tablet or drawing board between the stop block and the clamping plate.

The left and right sides of the contact block 502 are fixedly connected with horizontal plates 503 that extend through the movable cavity 4 to the left and right sides of the columnar base 1. The opposite side of the horizontal plate 503 is fixedly connected with the same swivel ring 6 located on the outside of the columnar base 1. The folding and collapsing assembly 9 includes a free hinge shaft 901, a cross link 902, and a connecting hinge shaft 903. The left and right sides of the fixed hinge shaft 8 are provided with free hinge shafts 901 that can move inside the guide groove 7. The outer sides of the fixed hinge shaft 8 and the free hinge shaft 901 are both fitted with cross links 902 that are distributed vertically and alternately. The two ends of adjacent cross links 902 are provided with connecting hinge shafts 903. Both sides of the cross link 902 that are not connected are provided with the same rectangular storage tube 10. The front cross link 902 is hinged to the outer lug of the rectangular storage tube 10, and the rear cross link 902 is movably connected to the outer lug of the rectangular storage tube 10 through a strip hole. The elastic clamping assembly 12 includes a hexagonal guide rod 121, a second spring 122, and a clamping plate 123.
