The slider and the nut are locked by the fastening pin and then are connected into a whole, and the screw and the nut are sold as a whole when purchased, so that the structure can avoid the increase of manufacturing cost due to the fact that threads matched with the screw are processed on the slider.

Further preferably, the base is injection molded, and the front end of the base gradually inclines upwards; the rear part of the base is provided with an upward vertical bending part for installing a motor; a limiting strip extending forwards and backwards is fixedly arranged above the base, and the sliding block is prevented from swinging when sliding forwards and backwards horizontally from the side surface; the side of base is provided with the turn-ups that the cross section is "7" font and constitutes the guide way, combines the seal of guide way front end, prevents the leading wheel slippage jointly.

Still preferably, the limit bar is located at the left side of the sliding block, the guide groove is located at the right side of the guide wheel, the length of the limit bar is matched with the stroke of the sliding block, the length of the guide groove is matched with the stroke of the guide wheel, and the rear end of the guide groove is flush with the front end of the limit bar. The limiting strips and the guide grooves limit or guide in the whole movement travel range, so that the shaking generated by a bumpy road surface is further prevented from affecting the stability of the movement of the mechanism.

Still preferably, a motor mounting via hole is provided at a position of the base close to the vertical bending portion, and the motor is fixedly mounted on the front wall of the vertical bending portion after passing through the motor mounting via hole. The structure is ingenious, the layout is reasonable, and the occupied space is reduced.

Further preferably, an arc-shaped protrusion with the same width as the sliding block is arranged below the sliding block, and the sliding block is in line contact with the base through the arc-shaped protrusion. Compared with surface contact, the linear contact has smaller friction and resistance, and smoother movement.

Further preferably, the operation control panel adopts split type structure, and by control panel main part and mounting panel coincide from top to bottom installation constitution, preceding landing leg, back landing leg all set up on the mounting panel, the mounting panel top is fixed a position through annular location arch with the bottom of operation control panel, and the fastener locking that combines again. Adopt split type structure, reduce the processing degree of difficulty of operation control panel to when the display screen breaks down or damages, only need change the control panel main part can, reduced use cost.

The invention has the beneficial effects that: through the mechanism, the operation control panel can slide forwards horizontally and then move upwards gradually, so that the front and back positions and the inclination angle of the operation control panel are adjusted, the operation and the observation of operators are facilitated, and the comfort is greatly improved; and the number of parts is small, and the functions are reliable.

Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

referring to fig. 1 to 4, a chair operation control sliding tilting mechanism mainly comprises an operation control board 1, a base 2, a sliding block 3, a motor 4, a screw rod 5, a guide wheel 6 and a nut 7.

A front leg 1a and a rear leg 1b are provided below the operation panel 1, and the front leg 1a and the rear leg 1b are preferably arranged in a figure of eight, the front leg 1a being for mounting the guide wheel 6, and the rear leg 1b being for hinging with the slider 3.

The base 2 is provided with a guide groove 2a matched with the guide wheel 6 for limiting the movement of the guide wheel 6, and the guide wheel 6 can only roll in the guide groove 2a. The motor 4 drives the sliding block 3 to horizontally slide back and forth on the base 2, and meanwhile the guide wheel 6 rolls in the guide groove 2a, so that the operation control panel 1 is driven to horizontally slide forward, and then rotates around a hinge point, so that the front end gradually inclines upwards relative to the rear end.

The sliding block 3 is sleeved on the screw rod 5 to form a screw rod nut mechanism, and the motor 4 drives the sliding block 3 to slide through the screw rod 5. Preferably, the sliding block 3 is embedded with a nut 7 matched with the screw rod 5, and the screw rod 5 drives the sliding block 3 to slide through the nut 7.
