Abstract
The utility model relates to a linkage bench rotation pedestal. The pedestal comprises a pedestal body, a fixed supporting disk and a rotary disk. The fixed supporting disk is installed on the pedestal body. An annular semi-circular slide groove is arranged in the rotary disk. Multiple roll balls are arranged in the annular semi-circular groove. Multiple spherical surface pits for positioning are arranged in the fixed supporting disk. The cooperation face between the fixed supporting disk and the rotary disk is the line contact supported by the roll balls. According to the utility model, roller paths and roll balls are designed between the rotation pedestal and the rotary disk, so cooperation relation between the supporting disk and the rotary disk is improved. Sliding friction is changed into rolling friction, so friction resistance is greatly reduced. A linkage bench seat can be rotated, positioned and adjusted in a large scope. The pedestal is comfortable to use and easy to maintain.

In technique scheme, described locking device also comprises geared sleeve device, and described geared sleeve device comprises internal gear and external gear, two in-line gears that described internal gear and external gear are mutual embedding, described handle is connected with internal gear, and locking rotating shaft is connected with external gear.
The utlity model has following beneficial effect:
1, the utility model will be designed to the structural type of raceway and ball between rotating base and rotating disc, improved the matching relationship between supporting disk and rotating disc, sliding friction is made into rolling friction, greatly reduced surface friction drag, joint action table seat can rotate and locate adjusting on a large scale, use comfortable, be convenient to maintenance.
2, positioning device utilizes eccentric wheel the spinning movement of handle to be converted to the vertical motion of positioning dowel, by interior outer gear sleeve regulating handle position, design ingenious, laborsaving convenience.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model joint action table rotating base.
Fig. 2 is the side view of the utility model joint action table rotating base.
In figure, 1-base, 2-fixed support dish, 3-rotating disc, 4-locks rotating shaft, the eccentric pinch roller of 5-, 6-positioning dowel, 7-spring, 8-ball, 9-base, 10-base, 11-handle, 12-external gear, 13-internal gear, 14-joint action table casing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, fixed support dish 2 is fixedly mounted on base 1, is provided with several balls 8 between rotating disc 3 and fixed support dish 2, between rotating disc 3 and fixed support dish 2, by ball 8, supports, and joint action table casing 14 is installed on rotating disc 3.On fixed support dish 2, be provided with several ball impressions for locating, rotating disc 3 is provided with annular semicircle chute 9, fitting surface between fixed support dish 2 and rotating disc 3 is the line contact that ball 8 supports, the ball impression that is used for locating ball 8 meets the degree of depth and position accuracy demand, improved the matching relationship between fixed support dish 2 and rotating disc 3, make sliding friction into rolling friction, greatly reduced surface friction drag.
The utility model also comprises the locking device of rotating disc 3, and this locking device comprises handle 11, geared sleeve device 10, locking rotating shaft 4, eccentric pinch roller 5, positioning dowel 6 and spring 7.Handle 11 is connected with eccentric pinch roller 5 by locking rotating shaft 4, eccentric pinch roller 5 is provided with positioning dowel 6, spring is located on 7 fixed support dishes 2, and positioning dowel 6 is holddown spring 7 under eccentric pinch roller 5 drives, until positioning dowel 6 contacts with fixed support dish 2, produces stiction.
Working procedure of the present utility model is as follows:
Operating grip 11 turns clockwise, by locking rotating shaft 4, drive eccentric pinch roller 5 rotations, because the rotary motion trace of the external frame of eccentric pinch roller 5 is involutes, it can promote positioning dowel 6 and move downward, the spring 7 that is positioned at positioning dowel 6 belows is compacted, when positioning dowel 6 touches fixed support dish 2, produce stiction, rotating disc 3 is fixed; Otherwise, in the time of need to cancelling location, by handle 11 counter-rotatings, eccentric pinch roller 5 rotations gradually release action are at the pressure at positioning dowel 6 tops, the spring 7 that is positioned at positioning dowel 6 belows discharges elastic force, positioning dowel 6 is upspring, and the stiction that positioning dowel 6 tops and fixedly support disc are 2 disappears, and rotating disc 3 can rotate location again.
In the present embodiment, geared sleeve device 10 comprises internal gear 12 and external gear 13, two in-line gears that internal gear 12 and external gear 13 are mutual embedding, and handle 11 is connected with internal gear 12, and locking rotating shaft 4 is connected with external gear 13.Handle 11 is when vertical position, for overcome handle 11 positioning action time the situation that is difficult for exerting oneself, external gear 12 can outwards be extracted certain displacement out, and internal gear 12 and external gear 13 no longer mesh, regulating handle position, drive the external gear 13 some tooth pitches of rotation separately, external gear 13 is resetted, now external gear 13 meshes with internal gear 12 gears again, and handle 11 rotarily drives internal gear 12 and moves together with external gear 13, repeat above-mentioned steps, realize the location to rotating disc 3.
