Description

Technical Field

[0001] The utility model relates to a HD-7030 fixed rotating bar chair foot. Background Art

[0002] At present, islands, water bars and bar counters are popular in home decoration. After the research of the company's marketing department, 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. At present, most of the chair legs in China are disc lift chair legs and fixed chair legs. The company's marketing department conducted a survey and some customers reported that the disc lift chair legs are heavier, and they will shake a little when they are raised to the highest position, which is not stable enough; while the fixed legs do not have the function of rotation, their practicality is limited, and the appearance design is not novel enough. Summary of the invention

[0003] The purpose of this utility model is to meet the needs of such customers. The weight of this utility model patent is similar to that of the fixed model, and it has a rotation function, which can meet the needs of customers. It is relatively practical and has a relatively novel and beautiful appearance design. In order to be suitable for bar counters of various heights, this utility model patent is equipped with a chair back. There are 6 kinds of seat heights (the height of the seat from the ground is called the seat height), namely 50cm, 55cm, 60cm, 65cm, 70cm, and 75cm.

[0004] In order to achieve the above purpose, the technical document adopted by the utility model is: a HD-7030 fixed rotating bar chair leg, which consists of a tray and a chair leg, which are connected by a rotating shaft in the middle. There is a 5mm thick steel plate at the top of the tray, which is slightly tilted backward. 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; there is a 30mm diameter round hole in the middle of the tray, and a steel round sleeve with a diameter of 30mm, a height of 35mm, and a thickness of 4mm extends around the round hole at the bottom of the tray. A 30mm diameter slot is reserved in the middle of the tray sleeve, which is connected to the top of the rotating shaft so that the chair can rotate 360 ​​degrees. There is a steel shaft sleeve with a diameter of 40mm, a height of 70mm and a thickness of 4mm in the middle of the chair leg, which is connected to the tail of the shaft. Four supporting feet are connected to the steel shaft sleeve. The four supporting feet are made of 30mmx15mm round flat cone tubes. The thickness of the round flat cone tube arm tube is 1.5mm and it is arc-shaped. The size from the cone tube to the bottom of the chair foot is 10mmx10mm. The chair foot is 250mm from the ground. There are three pedals on the front, left and right sides. The pedals are made of 30mmx15mm round flat cone tubes. The front pedal is made of mold bent tubes. There is a screw hole at the bottom of each of the four supporting feet with pre-embedded screw threads for installing plastic adjustment feet. The plastic adjustment feet play the role of mobile silencer, no scratching of the floor and leveling the chair feet.

[0005] Compared with the prior art, the utility model has the following effects: Most of the chair legs in China are now disc lift legs and fixed legs. According to the research of the company's marketing department, the disc lift legs are relatively heavy, and they will shake a little when raised to the highest position, which is not stable enough; while the fixed legs do not have the function of rotation, so their practicality is limited, and the appearance design is not novel enough. The utility model has a reasonable and simple structure, a high safety factor, and a more aesthetic appearance. The four supporting legs are made of 30mmx15mm round flat cone tubes. The thickness of the round flat cone tube arm tube is 1.5mm, which is in an arc shape. The tray and the chair legs are connected by a swivel in the middle. The structure is strong and durable, and the lines are more artistic. BRIEF DESCRIPTION OF THE DRAWINGS
