Description

说 明 书  Description
椅子调节支架 技术领域  Chair adjustment bracket
本发明涉及一种椅子的调节支架， 属于椅子制造技术领域。  The invention relates to an adjustment bracket for a chair, belonging to the technical field of chair manufacturing.
背景技术  Background technique
在椅子的众多功能中， 靠背是否可调节这一项， 成为了椅子档次 的分水岭。 为满足人们对办公等场合的高档椅需求， 各生产厂家纷纷 在试制靠背可调节的椅子。 如专利号为 CN200720105497. 9的中国专 利， 公开了一种椅子框架， 它能够实现靠背的调节。 这种椅子框架包 括底座、 扶手架、 坐垫架、 背靠架和连接底盘， 背靠架与扶手架活动 连接， 背靠架与坐垫架活动连接， 坐垫架两侧下部与连接底盘之间设 有滑杆机构，坐垫架的其中一侧下部与连接底盘之间设有滑杆定位机 构。这种椅子在调节靠背时，调节的力分散地作用在两个滑杆机构上 , 而且这两个分力的大小是不一样的，作用在一侧滑杆机构上的力常常 会阻碍另一侧滑杆机构的调节， 因此其调节困难； 另外， 在调节完成 后， 因为只有一边的滑杆机构有滑杆定位机构，使用者躺在椅子上一 旦出现身姿倾斜， 就会产生危害椅子滑竿定位机构的力， 常此以往会 使得椅子左右两侧慢慢地发生倾斜，甚至使得椅子的使用寿命大大缩 短； 如果两侧的滑杆机构均有滑竿定位机构， 那么调节靠背显然是一 个艰难又麻烦的事情。 发明内容 Among the many functions of the chair, whether the backrest can be adjusted or not becomes a watershed of the chair grade. In order to meet the demand for high-end chairs for office and other occasions, manufacturers have tried to make adjustable backrest chairs. For example, the Chinese patent of CN200720105497. 9 discloses a chair frame which can realize the adjustment of the backrest. The chair frame comprises a base, a handrail frame, a seat cushion frame, a backrest frame and a connecting chassis, the backrest frame is movably connected with the armrest frame, the backrest frame is movably connected with the seat cushion frame, and a lower side of the seat frame is connected between the lower part of the seat frame and the connecting chassis. The slide bar mechanism has a slide bar positioning mechanism disposed between one of the lower portions of the seat frame and the connecting chassis. When the chair adjusts the backrest, the adjusted force acts discretely on the two slider mechanisms, and the magnitudes of the two components are different. The force acting on one slider mechanism often hinders the other. The adjustment of the side slide bar mechanism makes it difficult to adjust; in addition, after the adjustment is completed, since only one side of the slide bar mechanism has a slide bar positioning mechanism, the user lying on the chair once the posture is tilted, the hazard of the chair slip occurs. The force of the positioning mechanism often causes the left and right sides of the chair to slowly tilt, which even shortens the service life of the chair. If the sliding bar mechanism on both sides has a sliding positioning mechanism, then adjusting the backrest is obviously a difficult one. Troublesome things. Summary of the invention

顶块直接接触滑杆， 锁定滑杆在套管内的滑动。顶块与滑杆的滑 槽相配合， 它们的接触面较大， 定位销迫使顶块顶住滑杆能够提供更 大的锁定力。 更为优选的技术方案是， 顶块与滑槽的接触面为曲面。 作为上述技术方案的优选， 套管上设有与定位销相配的定位销 套， 所述定位销套内固定有螺母； 所述定位销开设有与所述螺母相配 的螺紋。 The top block directly contacts the slide bar, locking the sliding of the slide bar within the sleeve. The top block cooperates with the chute of the slide bar, and their contact faces are large, and the positioning pin forces the top block against the slide bar to provide a greater locking force. A more preferable technical solution is that the contact surface of the top block and the sliding groove is a curved surface. Preferably, in the above technical solution, the sleeve is provided with a positioning pin sleeve matched with the positioning pin, and the positioning pin sleeve is fixed with a nut; the positioning pin is provided with a thread matched with the nut.
作为上述技术方案的优选， 支撑架上固连有一个底座连接件。 作为上述技术方案的优选， 所述调节杆的末端设置有手轮。  As a preferred embodiment of the above technical solution, a base connector is attached to the support frame. Preferably, as the above technical solution, the end of the adjustment lever is provided with a hand wheel.
作为优选， 所述滑杆上开设有与限位销相配的限位槽。  Preferably, the sliding rod is provided with a limiting groove matched with the limiting pin.
