Embodiment Construction

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The invention provides a hand clasping device, see for details figure 1 The difference between it and the prior art is that the device includes a cable, a handle seat and a handle set on the handle seat, and the handle and the handle seat are connected by the handle set on the handle seat. The shafts are connected; there is a rotatable roller on the buckle seat, and the roller has a certain thickness. Embedded on the wheel body of the buckle handwheel groove, so that the steel cable can be embedded in ...

Abstract

The invention relates to a hand clasping device. The hand clasping device comprises a dragline, a hand clasping seat and a hand clasp arranged on the hand clasping seat, wherein the hand clasp is connected with the hand clasping seat through a hand clasping shaft arranged on the hand clasping seat. A rotatable rolling wheel is arranged on the hand clasping seat, a rolling wheel groove is formed inthe outer portion of the rolling wheel, a dragline fixing end and a hand clasping wheel groove are formed in the hand clasp, one end of the dragline is fixed to the interior of the dragline fixing end, and the other end of the dragline is fixedly connected with the hand clasping seat through a fixing piece, and a steel cable in the middle of the dragline is sequentially wound around the hand clasping wheel groove and the rolling wheel groove. Two wheel grooves are formed in the hand clasping seat, the dragline is sequentially wound around the hand clasping wheel groove and the rolling wheel groove so as to be fixed, the friction resistance can be reduced through the joint effect of the two wheel grooves, the transmission method of force is changed, the effect of labor saving is obvious, and the practical operation is more humanized.

Description

technical field [0001] The invention relates to the technical field of unlocking devices, in particular to a handle device for unlocking with a zipper, in particular to a handle mechanism device for train seats. Background technique [0002] At present, most of the commonly used labor-saving unlocking devices adopt the principle of leverage, but due to the limitation of the mechanical structure volume, the lever arm must not be too long, so the labor-saving effect is not very obvious, and the unlocking force transmission direction is single, which is difficult for the actual operation and other related parts. Design has some influence. [0003] The unlocking device of this structure is not very suitable for mechanical components such as train seats, because there are certain restrictions and requirements for the volume of the machine, and the unlocking device needs to be matched with other parts, so the volume is too large, and not too large. The ideal force transmission ef...
