Description

Technical Field

[0001] The utility model relates to a HD-7029 lifting and rotating bar chair foot. Background Art

[0002] At present, islands, water bars and bar counters are popular in home decoration. After the company's marketing department's research, it will be a major trend in home decoration and dining room furniture, and the market prospects will be very good. At present, there are many sizes of islands, water bars and bar counters, which require bar chairs of different heights to match. Domestic customers are paying more and more attention to the appearance and quality of products. At present, most of the lifting and rotating bar chairs in China have round feet. After the company's marketing department's research, customers reported that the round feet occupy a large area, are too heavy, are not convenient to move, and the appearance design is not novel enough. Summary of the invention

[0003] The purpose of the utility model is to design a bar chair leg with a reasonable and simple structure, a high safety factor, a small footprint, a more aesthetic feel and a lifting and rotating function in view of the above shortcomings.

[0004] In order to achieve the above purpose, the technical document adopted by the utility model is: HD-7029 lifting and rotating bar chair legs, composed of three parts: tray, middle rod and chair legs, and the tray and chair legs are connected by the middle rod. There is a 5mm thick steel plate with a slight backward tilt at the top of the tray. The tilt angle of the tray conforms to the ergonomic sitting feeling. There are 4 screw holes at the four corners of the tray for fixing the back of the bar chair; a steel gas rod trigger is set just below the tray, and there is a handle on the lower right side of the tray. Pulling the handle upwards can trigger the gas rod to realize the lifting and rotating function of the bar chair. The middle pole is composed of a gas rod and a round footrest; the gas rod has a lifting stroke of 260mm; the round footrest is made of a 20mmX10mm square tube, which is die-cast into a 420mm diameter circle by a mold. There is a steel sleeve with a diameter of 55mm, a height of 30mm, and a thickness of 4mm in the middle of the circle. Three horizontal support rods extend from the outer round footrest to the center of the circle and are connected to the round footrest steel sleeve. The round footrest steel sleeve is sleeved on the gas rod and then welded to make the round footrest firm and not tilted. There is a steel sleeve with a diameter of 40mm, a height of 70mm, and a thickness of 4mm in the middle of the chair foot, which is connected to the tail of the middle pole. Four supporting feet are connected to the steel sleeve. The four supporting feet are made of 10mm steel plates cut by a mold laser. The shape is an arc claw, called a four-claw foot. A plastic foot pad is attached to the bottom of each of the four supporting feet. The 20mmX10mm square foot pad ensures that the chair moves silently, does not scratch the floor, and increases stability.

[0005] Compared with the prior art, the utility model has the following effects: Most of the lifting and rotating bar chair legs in China are disc-shaped. After the company's marketing department conducted a survey, customers reported that the disc-shaped legs occupy a large area, are too heavy, are not convenient to move, and are not novel in appearance. The utility model has a reasonable and simple structure, a high safety factor, a small footprint, and is more aesthetic with lifting and rotating bar chair legs; the round footrest surrounds a circle, and the footrest can be stepped on at any angle when rotating, making it more convenient to use; the four supporting feet are made of 10mm steel plates cut by a mold laser, and are shaped like arc claws, called four-claw feet. The tray and the chair legs are connected by a swivel in the middle, and the structure is strong and durable, and the lines are more artistic. BRIEF DESCRIPTION OF THE DRAWINGS
