Problems solved by technology
One is that the fixed rib plate 12 and the round pipe bracket 10 are generally connected by a circular tube socket. After a long time of use, the connection is prone to loosening, and friction between the rib plate and the round tube bracket will generate noise. , in order to avoid this problem, some manufacturers fix it with the bracket by welding after one end of the rib plate is socketed with the round tube bracket, which increases the production cost and weld scars will cause appearance defects , and, when the seat is moved, the socket fixing part 1201 will rub against the ground, which will scratch the expensive floor or carpet; the second is that the round tube bracket 10 is prone to deformation, which will cause the seat to be placed on the ground unsteadily. Shaking, in order to reduce this problem, the manufacturer set up a plurality of pads 102 at the place where the bottom of the round pipe bracket is in contact with the ground. Similarly, this design also increases the cost, and after a long time of use, due to the deformation of the pads Inconsistent, still can not solve the problem of stability, in addition, the setting of block also can cause damage to floor or carpet when seat moves; , the square fixed disk 14 is prone to deformation, and as a result, during use, there will be interference between the rotating disk 18 and the square fixed disk 14, and harsh noise will be generated when rotating, which will affect the user's experience.

The invention provides an improved seat disc base which comprises an outer side part and a middle recessed part, wherein an angle is formed between the outer side part and the ground; the middle of the recessed part is of a horizontal structure and is connected with and mounted on a rotating disc; flanges arranged adjacent to one another are formed in the horizontal structure; a ball groove in which a ball is placed is formed between every two adjacent flanges; the outer side part, the recessed part and the flanges of the disc base are integrally molded by plates; an edge part where the disc base is in contact with the ground is of a tubular structure. The seat disc base is integrally molded by integral plates such as steel plates, a square fixing disc connected with and mounted on the rotating disc does not need to be fixed in manners such as welding and screw fixing, and lots of manual cost is saved; the deformation resistance is excellent, the seat stability is excellent, a noise problem during use is avoided, and user experience is excellent; moreover, the edge part in contact with the grounds is in the round tube design, damage to floor or carpets is avoided, and the seat disc base is particularly applicable to high-grade seats.
Description
technical field [0001] The invention relates to the technical field of mechanical design, in particular to an improved seat disc base. Background technique [0002] The swivel chair is a common office and home seat, which can provide people with a comfortable office or rest environment. In addition to ensuring sufficient mechanical strength to ensure safety, the stability of the swivel chair on the ground and the smoothness of rotation are important considerations when designing the swivel chair. Such as figure 1 As shown, the current rotating seat base generally includes a circular tube support 10, on which a plurality of ribs 12 are connected, a square fixed plate 14 is fixed on the ribs 12 by means of screws, and a rotating disc 18 is connected to the square The fixed disk 14 is connected and can rotate relative to the square fixed disk. In the seat base structure of this structure, there are several problems. One is that the fixed rib plate 12 and the round pipe brac...
