Description

Handle mechanism assembly

Technical Field

The utility model belongs to the technical field of the chair handrail, especially, relate to a hand (hold) mechanism assembly.

Background

The handlebars, also called armrests, of the chair are used to support the hands of the user, thereby improving the comfort of the user. Some handles are fixedly installed on the seat through bolts, so that the angle can not be adjusted, and the comfort is poor. Some handlebars are installed on the side portion of the seat in a folding mode, in the prior art, most of the foldable handlebars are folded through simple rotating assembly, gear adjustment cannot be performed on the handlebars, namely the handlebars only have two positions, namely an initial point and a termination point, so that the handlebars cannot meet the use requirements of users with different body shapes, and the comfort is further improved. Even if a small part of the handlebars have a multi-gear adjusting function, the handlebars with the multi-gear adjusting function still have the technical defects of excessively complex structure, high manufacturing cost, easiness in damage and the like.

Disclosure of Invention

The utility model aims at providing a handlebar mechanism assembly to the not enough of above-mentioned prior art existence.

The utility model adopts the technical proposal that: a handle mechanism assembly comprises a handle structure with an inner cavity, wherein corresponding shaft holes are formed in the front side wall and the rear side wall of the right end of the handle structure, a rotating shaft is mounted on each shaft hole, a mounting hole is formed in the axis of each rotating shaft, a gear is sleeved on each rotating shaft, and the gear is located in the inner cavity; an installation seat is arranged in an inner cavity on the left side of the gear, a sliding chute is arranged in the installation seat, a sliding block is arranged in the sliding chute, a tooth structure meshed with the gear is arranged at the right end of the sliding block, a pull rope is connected to the left end of the sliding block, and a return spring is arranged between the left end of the sliding block and the inner side wall of the left end of the sliding chute; the handle structure is characterized in that a hinge pin is connected between the front side wall and the rear side wall of the left end of the handle structure, an adjusting rod is hinged to the hinge pin and located in the inner cavity, and the right end of the adjusting rod is connected with the pull rope.

The middle part of adjusting the pole is equipped with the hinge hole to through hinge hole and round pin hub connection, the right-hand member of adjusting the pole is the link, is connected with the stay cord, the left end of adjusting the pole is the driving lever.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model has the advantages of simple structure, the nature that can control is good, has many gears and adjusts, can satisfy the user use of different sizes, and the travelling comfort is good.
