Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, the present embodiment provides an adjustable seat control handle, which comprises an armrest 1, wherein one end of the armrest 1 is rotatably mounted on a seat 2, and the other end is mounted with a handle 3, and the surface of the armrest 1 can rotate to a substantially horizontal state shown in fig. 1 or a substantially flush state with a seat back 21 shown in fig. 2.

This embodiment installs handle 3 on handrail 1 to set up handrail 1 as the back of the chair relatively and rotate and accomodate, make things convenient for personnel to pass in and out, when not using, can pack up the handle, the increase is taken the space, improves travelling comfort and convenience, and handrail after accomodating does not influence the visual impression of whole seat, and is less to the collocation effect influence of seat and whole environment.

Referring to fig. 1 again, when the armrest 1 is in the horizontal state, the handle 3 is cubic to the end of the armrest 1, so as to facilitate manipulation, and in conjunction with fig. 3, when the armrest rotates between the substantially horizontal state shown in fig. 1 and the storage state shown in fig. 2, the posture of the handle 3 relative to the ground remains unchanged, so that the posture can be kept stable in any state, and an operator can complete operation by using the same operation behavior in any state conveniently, and does not need to adjust the swing direction of the handle 3 during control according to the rotation angle of the armrest 1, so that the armrest is friendly to use.

Referring to fig. 4, the armrest 1 is further provided with a connecting rod 4, two ends of the connecting rod 4 are respectively hinged to the seat 2 and the handle 3, hinge shafts at two ends of the connecting rod 4 and hinge shafts at two ends of the armrest form four points of a parallelogram, the hinge shafts of the connecting rod 4 and the seat 2 are located below the hinge shafts of the armrest 1 and the seat 2, when the armrest 1 rotates, the connecting rod 4 can rotate along with the armrest 1 because the hinge shafts of the connecting rod 4 and the armrest 1 matched with the seat are unchanged, and the connecting rod 4 and the armrest 1 are parallel to keep the two hinge shafts of the handle 3 connected with the armrest 1 and the connecting rod 4 stationary relatively, so that the posture of the handle 3 is kept unchanged all the time.

Specifically, the armrest 1 is connected with the fixed support 5 through the first hinge shaft 51, the fixed support 5 is fixed on the side surface of the seat back 21, the fixed support 5 is provided with a third hinge shaft 52 below the first hinge shaft 51, and the connecting rod 4 is in hinge fit with the fixed support 5 through the third hinge shaft 52.

A fixing column 31 arranged in the vertical direction is fixed on the handle 3, the upper end of the fixing column 31 is hinged to the armrest 1 through a second hinge shaft 32, and the lower end of the fixing column 31 is hinged to the connecting rod 4 through a fourth hinge shaft 33.

A first limit screw 53 is screwed to the fixing bracket 5 in the vertical direction, when the armrest 1 is in a substantially horizontal state as shown in fig. 4, the end of the first limit screw 53 abuts against the lower surface of the armrest 1, so as to support the armrest 1, and the position of the armrest 1 can be adjusted by screwing the position of the first limit screw 53.

Further, a second limit screw 54 is screwed and fixed on the fixing support 5 along the horizontal direction, the second limit screw 54 is fixed above the first hinge shaft 51 and is positioned at one side far away from the rotation area of the armrest 1, when the armrest 1 is in a state of being basically flush with the seat back 21 as shown in fig. 5, the end of the second limit screw 54 abuts against the surface of the armrest 1, and the limit of the adjustment range of the armrest 1 is realized through the i limit screw 53 and the second limit screw 54. And the rotational adjustment range of the armrest 1 can be changed by finely adjusting the first limit screw 53 and the second limit screw 54.

With reference to fig. 4 and 5, a jackscrew 55 is fixed to the fixing bracket 5 in a threaded manner in the vertical direction, an end of the jackscrew 55 points to the center of the first hinge shaft 51, and the jackscrew 55 can rotate relative to the fixing bracket 5 to adjust the position in the vertical direction, so that the extension length is changed, the jackscrew 55 tightly pushes the armrest 1, the position of the armrest 1 can be locked, and the armrest 1 is prevented from accidentally falling off at a fixed position.

Furthermore, a limiting hole (not shown) is further formed in the outer contour of the position where the armrest 1 is matched with the first hinge shaft 51, when the armrest 1 is basically flush with the seat back 21, the jackscrew 55 can be rotatably inserted into the limiting hole, so that the armrest 1 can be locked, and when the armrest 1 needs to be locked in other positions, the limiting hole can be adaptively arranged at a determined position.
