Description

Technical Field

[0001] This utility model relates to the field of chairs, and in particular to a connecting member for chairs. Background Technology

[0002] Existing chair mounting structures for installing pivots or cylinders use bolts installed from the bottom, requiring the chair to be tilted for assembly and disassembly, which is inconvenient.

[0003] For example, patent document CN208837386U discloses a swivel chair, including a chair support device, a bearing device, and a chassis. The chair support device includes a bracket and a rotating shaft. The rotating shaft is detachably mounted on the bracket. The bearing device includes at least one bearing, fasteners, and a mounting sleeve. At least one bearing is axially arranged side by side on the rotating shaft and housed within the mounting sleeve. The rotating shaft is fastened to the chassis by fasteners. The bearing device is fixed to the chassis. The rotating shaft acts on the bearing and rotates using the bearing.

[0004] For example, patent document CN102176847B discloses a chair in which the support is supported by chair legs and the seat is supported by the support. The backrest support rod is generally L-shaped in side view. Its upright part facing upward and its forward part facing forward are connected to each other by a bend. The front part of the forward part of the backrest support rod is mounted on the support and the backrest is supported by the upright part. The chair is covered by a protective cover at least by the portion of the backrest support rod from the rear surface of the bend to the lower surface.

[0005] To address this issue, a connector for chairs is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a connector for chairs, which has the advantages of simple structure and easy assembly of chairs.

[0007] The technical solution adopted by this utility model to solve the problem is: a connecting part for a chair, including: a base plate, a sleeve provided on the top of the base plate, a top plate provided on the top of the sleeve, the top plate and the base plate being connected by bolts, and the bolts extending downward from the top plate to connect to the base plate.

[0008] As a further improvement to the above technical solution, the base plate is provided with a plurality of first connecting ears, each of which has a threaded hole, and the top plate is provided with a second connecting ear corresponding to the first connecting ears, each of which has a through hole.

[0009] As a further improvement to the above technical solution, the top of the sleeve is provided with a boss, the top plate is sleeved on the sleeve, and the bottom of the top plate abuts against the boss.

[0010] As a further improvement to the above technical solution, the base plate is welded and fixed to the sleeve.

[0011] The advantages of this utility model are: it uses a sleeve to connect the seat shaft or cylinder, and the sleeve is installed on the seat leg by bolts. The bolts are installed from top to bottom, which is convenient to operate and has a simple structure; it greatly reduces the volume occupied by loading and saves transportation costs.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 4 A connector for a chair includes: a base plate 1, a sleeve 2 on the top of the base plate 1, a top plate 3 on the top of the sleeve 2, and the top plate 3 connected to the base plate 1 by bolts 4. The bolts 4 extend downward from the top plate 3 to connect to the base plate 1. By connecting the top plate 3 and the base plate 1 with bolts 4, the sleeve 2 can be fixed. Then, the seat's pivot or cylinder can be inserted into the sleeve 2 to complete the assembly. Since the sleeve 2 is fixed by bolts 4 installed from top to bottom, the operation is convenient.

[0023] In a preferred embodiment, the base plate 1 is provided with a plurality of first connecting ears 11, each with a threaded hole 12. The top plate 3 is provided with a second connecting ear 31 corresponding to the first connecting ears 11, each with a through hole 32. In use, the bolt 4 passes through the through hole 32 and is threaded into the threaded hole 12. The number of seat legs 5 is the same as the number of bolts 4. The seat legs 5 are installed around the sleeve 2, and the seat legs 5 have insertion holes through which the bolts pass. The base plate 1 and the top plate 3 are respectively fitted to the bottom and top of the seat legs 5, so that the connector can be installed on the seat legs 5. At the same time, to ensure a more stable installation, there are embedding grooves at the top and bottom of the seat legs 5. The first connecting ears 11 and the second connecting ears 31 are respectively embedded in the corresponding embedding grooves, so that the seat legs 5 will not swing left and right relative to the sleeve 2 after connection.

[0024] In a preferred embodiment, the top of the sleeve 2 is provided with a boss 21, and the top plate 3 is sleeved on the sleeve 2, with the bottom of the top plate 3 abutting against the boss 21. This ensures a stable connection between the top plate 3 and the sleeve 2, preventing any displacement.

[0025] In a preferred embodiment, the base plate 1 is welded and fixed to the sleeve 2.

[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
