Fixing piece, driving mechanism are played, the ball screw and chair framework are rigidly connected, and the sliding rack rigidly connects with chair basin
It connects, the front end of the ball wire lever pin and the ball screw forms ball screw assembly, and the ball wire lever pin can enter described
In the lock hole of sliding rack, the driving mechanism and the ball wire lever pin are flexibly connected, and the rebound fixing piece is connected and fixed
In the tail portion of the ball screw, the rebounding mechanism is assemblied between the ball wire lever pin and the rebound fixing piece,
Preferably, the driving mechanism includes motor, roller and adjusts wirerope, and described one end for adjusting wirerope is fixed
On which cylinder, the motor can drive the roller to rotate, the other end and the ball-screw for adjusting wirerope
Pin flexible connection.
Preferably, the tail portion of the other end for adjusting wirerope and the ball wire lever pin is flexibly connected.
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 present invention are: provided in an embodiment of the present invention roll combines sliding locking mechanism, in original adjusting
On the basis of mechanism, adjustment pin is connected using ball screw assembly, ball screw is fixed with skeleton, and ball wire lever pin is regulated machine
The effect of structure external force rolls when while exiting from the sliding of the lock hole of sliding rack, reduces ball wire lever pin and lock hole
Between frictional force, simultaneously because ball screw assembly, have not self-locking characteristic, make ball under the rebound effect of compressed spring
Lead screw pin enters the lock hole of sliding rack when rolling, and locks regulating mechanism.So locking mechanism provided by the invention,
Seat upper and lower position is adjusted in operating process, and sliding friction is made to be changed into rolling sliding friction, and reducing seat and people's self weight makes
" hole " gives " 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 in an embodiment of the present invention for rolling and combining sliding locking mechanism；
Fig. 2 is the working state schematic representation provided in an embodiment of the present invention 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 objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.It should be appreciated that the specific embodiments described herein are only used to explain the present invention, it is not used to
Limit the present invention.
As shown in Figs. 1-2, the embodiment of the invention provides a kind of roll to combine sliding locking mechanism, comprising: ball-screw
Pin 1, ball screw 2, sliding rack 3, rebounding mechanism 4, rebound fixing piece 5, driving mechanism, the ball screw 2 and chair framework 7
Rigid connection, the sliding rack 3 are rigidly connected with chair basin 8, the front end of the ball wire lever pin 1 and the ball screw 2
Formed ball screw assembly, the ball wire lever pin 1 can enter the sliding rack 3 lock hole in, the driving mechanism with it is described
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 rebounding mechanism
4 are 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 invention, obtained following beneficial effect: the embodiment of the present invention is mentioned
The rolling combination sliding locking mechanism of confession connects adjustment pin, ball using ball screw assembly, on the basis of original regulating mechanism
Screw is fixed with skeleton, and ball wire lever pin is regulated the effect of mechanism external force, while exited from the sliding of the lock hole of sliding rack
Side rolls simultaneously, reduces the frictional force between ball wire lever pin and lock hole, simultaneously because ball screw assembly, is not with self-locking
Characteristic, so that ball wire lever pin is entered the lock hole of sliding rack when rolling under the rebound effect of compressed spring, make adjusting machine
Structure locking.So locking mechanism provided by the invention, descends position to adjust in operating process on the seat, changes sliding friction
To roll sliding friction, reducing seat and people's self weight makes " hole " to give " pin " bring sliding friction, improves regulating mechanism lock
Fixed, unlock fluency and user experience.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
Depending on protection scope of the present invention.
