Description

Technical Field

[0001] This utility model belongs to the field of bar stool technology, specifically a modular bar stool that is easy to assemble. Background Technology

[0002] Bar stools are similar to regular chairs, but the seat of a bar stool is usually higher off the ground. Bar stools got their name from their original use in bars. With the development of the times and the influence of fashion trends, bar stools have also begun to be used in more and more places such as restaurants and cafes.

[0003] In the existing technology, there is a chair with easy assembly, which is disclosed in CN205548047U. When the chair leg steel tube is pressed down, the two sides of the chair leg fixing buckle are opened by force. After the chair leg steel tube enters the chair leg steel tube connecting groove, the two sides of the chair leg fixing buckle return to their original shape and wrap around the chair leg steel tube. Under the action of the protruding teeth, the friction between the chair leg steel tube and the chair leg steel tube connecting groove increases, so that the chair leg and the chair seat are firmly connected together. When disassembling, you only need to press the chair leg and pull the chair seat upward to easily disassemble it. This chair is easy to assemble and is simple to operate and convenient to use. However, in general, bar stools are assembled by assembling the backrest and support legs separately, making it impossible to disassemble and replace the seat cushion. This significantly increases maintenance costs. When the seat cushion is worn or soiled, the entire seat frame unit needs to be replaced, resulting in resource waste. Cleaning and maintenance are extremely inconvenient, and the fixed structure makes it difficult to thoroughly clean stains from the gaps, affecting hygiene. Personalization and functionality are limited, and users cannot change the seat cushion to different materials or thicknesses according to their needs. To address these issues, we provide a modular bar stool that is easy to assemble. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of easy installation and removal of seat cushions for replacement, as well as the separate assembly of backrest cushions and bar stool support legs, a modular bar stool that is easy to assemble is proposed.

[0013] The beneficial effects of this utility model are: The seat cushion removal assembly of this utility model allows for easy installation and removal of the seat cushion. A pull block moves a movable plate, which in turn moves an adjusting plate and a telescopic rod. The adjusting plate slides stably through a sliding engagement between a slider and a groove. The telescopic rod then moves an adjusting disc, causing the plug to move out of the second slot and release the seat cushion. Conversely, a return spring retracts the plug into the second slot, securing the seat cushion. This facilitates easy installation and removal of the seat cushion, simplifying maintenance and enhancing the practicality of the modular design, effectively reducing assembly time and operational complexity.

[0014] The backrest cushion assembly of this utility model involves inserting a plate into a first slot so that the first threaded hole corresponds to the second threaded hole. Then, the first fixing bolt is rotated through the first threaded hole and then rotated into the second threaded hole to restrict the backrest cushion, thereby assembling the backrest cushion and improving the convenience of self-assembly for users.

[0015] The bar stool support leg assembly of this utility model uses a T-shaped slider inserted into a T-shaped groove, so that the third threaded hole and the fourth threaded hole correspond to each other. Then, the second fixing bolt is rotated through the third threaded hole and then rotated into the fourth threaded hole to fix the T-shaped slider and the bar stool support leg. Conversely, after the second fixing bolt is rotated out, the restriction between the T-shaped slider and the bar stool support leg is released, thereby facilitating the assembly of the bar stool support leg and improving assembly efficiency.
