Preferably, the rebounding mechanism is compressed spring, and the rebound fixing piece is spring mountings.
Preferably, the spring mountings are connected through a screw thread the tail portion for being fixed on the ball screw.
The beneficial effects of the utility model are: provided by the embodiment of the utility model roll combines sliding locking mechanism,
On the basis of original regulating mechanism, connect adjustment pin using ball screw assembly, ball screw fixes with skeleton, ball wire lever pin by
To the effect of regulating mechanism external force, is rolled when while being exited from the sliding of the lock hole of sliding rack, reduce ball wire lever pin
Frictional force between lock hole, simultaneously because ball screw assembly, has not self-locking characteristic, in the rebound effect of compressed spring
Under so that ball wire lever pin is entered the lock hole of sliding rack when rolling, lock regulating mechanism.So provided by the utility model
Locking mechanism descends position to adjust in operating process on the seat, so that sliding friction is changed into rolling sliding friction, reduce seat
And people's self weight makes " hole " to give " pin " bring sliding friction, improves regulating mechanism locking, unlock fluency and user experience.
Detailed description of the invention
Fig. 1 is the structural schematic diagram provided by the embodiment of the utility model for rolling and combining sliding locking mechanism；
Fig. 2 is the working state schematic representation provided by the embodiment of the utility model for rolling and combining sliding locking mechanism.
In figure, the meaning of each symbol is as follows:
1 ball wire lever pin, 2 ball screws, 3 sliding racks, 4 rebounding mechanisms, 5 rebound fixing pieces, 6 adjust wirerope, 7 seats
Skeleton, 8 chair basins, 9 linear bearings.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.It should be appreciated that the specific embodiments described herein are only used to explain that this is practical
It is novel, it is not used to limit the utility model.
As shown in Figs. 1-2, the utility model embodiment provides a kind of roll and combines sliding locking mechanism, comprising: ball
Lead screw pin 1, ball screw 2, sliding rack 3, rebounding mechanism 4, rebound fixing piece 5, driving mechanism, the ball screw 2 and seat
Skeleton 7 is rigidly connected, and the sliding rack 3 is rigidly connected with chair basin 8, the ball wire lever pin 1 and the ball screw 2
Front end formed ball screw assembly, the ball wire lever pin 1 can enter the sliding rack 3 lock hole in, the driving mechanism with
The ball wire lever pin 1 is flexibly connected, and the rebound fixing piece 5 is fastened on the tail portion of the ball screw 2, the rebound
Mechanism 4 is assemblied between the ball wire lever pin 1 and the rebound fixing piece 5.
When the locking mechanism operation of above structure, pulls and adjust wirerope (driving mechanism), since ball screw is fixed, rolling
Ballscrew pin is slided when rolling and is exited in sliding rack lock hole, and chair basin realizes up and down adjustment；When locking, ball wire
Screen resilience of the lever pin by rebounding mechanism (compressed spring), while " the not self-locking performance " of ball-screw is benefited from, make ball-screw
The lock hole for entering sliding rack when rolling is sold, realizes the upper and lower position locking of chair basin.
In the present embodiment, the driving mechanism may include motor, roller and adjusting wirerope 6, the adjusting wirerope 6
One end it is fixed on which cylinder, the motor can drive the roller to rotate, the other end for adjusting wirerope 6 and institute
State the flexible connection of ball wire lever pin 1.
In the case where ball screw 2 is fixed, when external force F is applied on ball wire lever pin 1,1 edge of ball wire lever pin can be made
Itself is radial rolling and along itself slide axially (unlocking process), and because ball screw assembly, has not self-locking characteristic, if external force-
F is applied on ball wire lever pin 1, can obtain movement effects (locking process) in contrast, while biggish screw thread may be selected
Lift angle is to reduce the self-locking performance of ball screw assembly,.
Further, the tail portion of the other end for adjusting wirerope 6 and the ball wire lever pin 1 is flexibly connected.
Herein using flexible connection, the other end for adjusting wirerope 6 can smoothly pull ball wire lever pin 1 complete under driving force
At the locking and unlock of system, and convenient for adjusting the dismounting between wirerope 6 and ball wire lever pin 1, obtain system maintenance
It ensures.
In the present embodiment, the rebounding mechanism 4 can be compressed spring, and the rebound fixing piece 5 can be fixed for spring
Part.
Compressed spring is more commonly used rebounding mechanism, and is conveniently easy to get, and is lasted a long time, so, using compressed spring
As rebounding mechanism, be conducive in locking, screen resilience of the ball wire lever pin by compressed spring enables to roll quasi- lead screw pin side
It rolls, while entering in the lock hole of sliding rack, realizes the locking of the upper and lower position of chair basin.
In the present embodiment, the spring mountings are connected through a screw thread the tail portion for being fixed on the ball screw 2.
Using the above structure, it can be convenient the dismounting of spring mountings, also facilitate the update to compressed spring.
By using above-mentioned technical proposal disclosed by the utility model, following beneficial effect: the utility model has been obtained
The rolling combination sliding locking mechanism that embodiment provides is connected using ball screw assembly, and is adjusted on the basis of original regulating mechanism
Section pin, ball screw are fixed with skeleton, and ball wire lever pin is regulated the effect of mechanism external force, while sliding from the lock hole of sliding rack
Side rolling while exiting is moved, the frictional force between ball wire lever pin and lock hole is reduced, simultaneously because ball screw assembly, has
There is not self-locking characteristic, ball wire lever pin made to enter the lock hole of sliding rack when rolling under the rebound effect of compressed spring,
Lock regulating mechanism.So locking mechanism provided by the utility model, descends position to adjust in operating process on the seat, makes
Sliding friction is changed into rolling sliding friction, and reducing seat and people's self weight makes " hole " to give " pin " bring sliding friction, is promoted
Regulating mechanism locking, unlock fluency and user experience.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching should also regard the protection scope of the utility model.
