Description of new models: [Technical field to which new models belong] This creation relates to a seat cushion rotation structure, especially an innovative design of a seat rotation structure that can make the rotation of the seat cushion more frequent. [Previous technology] In order to meet the needs of consumers, chairpersons have successively developed a number of different chairs, such as chairs that can be rotated, adjustable in height, or adjustable in tilt of the back of the chair. # In terms of chairs that can be turned around, children are naturally active and active, so when children use the above rotatable chairs, they often use the chairs as rotating toys, causing damage to the chairs or Dangerous. Furthermore, if younger children climb up the chair, it will also cause the chair to spin. Therefore, the creator created a chair that can fix the rotating seat cushion 'and applied to the Jun Bureau on May 19, 2003, and published it in the Patent Gazette of March 11, 2004. As for the chair seat rotation preventing structure, the fixed seat convex sleeve is attached to the bottom side for the sleeve part of the top of the support rod in the center of the foot seat to be sleeved, and the sleeve is fixed to the outside. The anti-broadcasting structure is relatively small at one end of the abutting rod. The rod is used to sleeve the spring after it is sleeved. The end of the connecting rod passes through the abutting wall of the outer end of the fixed cylinder and is pivotally fixed to the pivot of the plate. Tow 2 is provided at one place with the contact portion close to the pivot point, and at the other place is provided with two other contact portions that are farther away from the n ff point. Furthermore, the poetry tool of the sleeve is provided with a through hole for arrival. The inner end of the rod passes through the sleeve, and the socket of the support rod is provided with a plurality of grooves M266800. The abutting end of the rod will move the plate body, so that the-abutting portion and the fixed end of the fixed barrel will protrude into a recess. The groove prevents the seat cushion from rotating. However, because the case considers the socket part of the supporting rod assembled in the sleeve of the fixed seat when the young child is riding, the prevention of seat rotation can be achieved by I = lost in the groove of the socket part; this- The design method did not expect to keep the seat cushion that the seat cushion can rotate smoothly. The inner wall of the barrel is in contact with the outer periphery of the socket, so that the rotary seat belt _set-and rotates when there is an obstacle between the sleeve and the socket The frictional force of the rotation makes the seat cushion unable to rotate smoothly and rubs the noise. Wei Ya Wang Shao [New content] The reason is that the creators have a spirit to improve the lack of the above-mentioned conventional structure, supplemented by its rich expertise and years of practical experience. After many tests, I finally carefully developed a book about the seat cushion rotation structure, which is mainly set up and down bearings on the chair support rods, and the upper and lower bearings are located separately, socket After the upper and lower parts are sleeved and combined with the sleeve of the fixed seat under the seat cushion, the establishment of upper and lower bearings can be used to make the seat cushion smoother during rotation. [Embodiment] In order to make the technical means and effects achieved in this creation easy to understand, here are the explanations with the drawings: First, please refer to the first to third pictures. The rotating structure of the chair of this creation is based on The bottom side of the fixed seat (1) with the seat cushion is provided with a convex sleeve (11) for receiving a supporting rod (2) at the center of the foot seat, and a socket is provided on the upper end of the supporting rod (magic M266800). ⑼, and make the sleeve ⑼ slightly smaller than the sleeve ("1) '!' Place the sleeve (21) in the sleeve ⑴) and leave it in a non-contact shape, and then insert the sleeve j (21 ) Establish a number of inwardly recessed grooves. · Following the upper rod ⑵, upper and lower bearings ⑽, ⑵ are set, and the upper and lower bearings (, 22), (23) are located in the socket.上 the upper and lower parts; further, the sleeve (the outer part of the 具 is provided with a connecting part (12), the connecting part 〇2) is provided with a threaded section (121), and the sleeve ⑴ is provided with a through Hole ⑽; fixed at the corresponding joint (12)-a stop structure ⑶, the stop structure ⑶ is attached to the rod (31)-a small diameter connecting rod (311) at the end for the spring (32) Then put on the hollow The abutting wall (331) protruding from the outer end of the fixing cylinder (33) inside the fixing cylinder (33) is pivotally fixed with the pivoting portion (341) of the plate body (34), and the other of one rod (31) The end is an abutting end (312), and the abutting end (312) can pass through the through hole (13) of the sleeve (11) correspondingly into the groove (2ι) of the socket (2) socket part (21). The inner end of the fixed cylinder (33) is provided with a threaded section (332) for screwing with the threaded section (121) of the joint section (12), and the curved pivotal section (341) The first abutting portion (342) located closer to the pivot point and the second abutting portion (343) located farther from the pivot point are provided. '" " Please refer to the second and third figures. In general, the stop structure is formed by the second abutment portion (343) of the plate (34) and the outer end of the fixed cylinder (33), so that the abutment rod (31) is slightly extended, the spring (32) is in a compressed state, and the abutment end (312) of the abutment rod (31) does not extend into the groove (2Π) of the support rod (2). At this time, since the fixed seat (1) on the bottom side of the seat cushion is set by the sleeve (11) and the top and bottom bearings (22) and (23) of the top of the support rod (2), the user can Smooth rotation seat 塾 Refer to the fourth and fifth figures. When you want to prevent the seat cushion from rotating, you can move the plate (34) so that its abutment (342) gradually slides to the fixed cylinder. The outer end of M266800 (33) ㈣'briber spring (32) will stretch, and the abutment end (312) of the screw rod (3) will extend into one of the grooves (within 2 支) of the support rod ⑵ socket part 借此. With this, you can click Against the sleeve ⑴) and the socket ⑼ to prevent the seat 塾 from rotating. From the above structure, it can be known that the creation uses upper and lower bearings respectively at the upper and lower parts of the socket of the support rod, so that after the support rod is connected to the sleeve of the fixed seat, the friction is reduced when the seat cushion is rotated. The generation of force makes the rotation of the seatpost more smooth. "The above-mentioned 'implementation examples of the creation can indeed achieve the expected use effect, and the specific structure disclosed, Qian has never been seen in various products' nor has it been disclosed before the application. Regulations and requirements: According to the law, an application for a new patent is submitted for examination, and the patent is granted. It is a good idea.
