Description

Technical Field

[0001] This utility model relates to a handrail structure, and more particularly to a sliding adjustable handrail structure. Background Technology

[0002] Currently, office chair armrests on the market are typically fixed, with some featuring height adjustment. When a user leans back, the armrests don't move backward. When the angle of inclination is slightly too large, the elbow only touches the back of the armrest, instead of the entire arm touching the armrest surface. This prevents the arm from being in a comfortable position when resting, affecting the user experience. Therefore, it is necessary to provide a sliding adjustable armrest structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sliding adjustable handrail structure, which solves the problem that the existing handrail structure cannot be smoothly moved and adjusted.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a sliding adjustable handrail structure, including a handrail body, wherein a PU lower support surface is provided on the handrail body, a slide plate and a button are provided on the PU lower support surface, a button transition piece and a spring are provided between the button and the slide plate, a left and right sliding pressure strip is provided on the button transition piece, a left and right fixing piece is installed on the slide plate, and a PU pad is provided on the top of the PU lower support surface; the button and the PU pad are connected by a locking tooth, and the left and right fixing pieces and the left and right sliding pressure strips are connected by a locking tooth; when the button is pressed, it disengages from the locking tooth of the PU pad, and at the same time, the button transition piece drives the left and right fixing pieces and the left and right sliding pressure strip locking teeth to disengage, so that the PU pad slides left, right and back and forth.

[0005] Furthermore, the PU pad is locked to the PU underside by flat-head self-tapping screws.

[0006] Furthermore, the two ends of the left and right sliding pressure strips are fixed to the button transition piece by cross-headed washer screws.

[0007] Furthermore, the armrest body is provided with a positioning post, and the PU lower support surface is provided with a positioning groove that matches the positioning post.

[0008] Furthermore, the PU pad has a slot, and the PU lower support surface has a button receiving part, with the slot on the PU pad engaging with the button receiving part.

[0009] Compared with the prior art, the present invention has the following advantages: the sliding adjustable handrail structure provided by the present invention is not only easy to move and adjust smoothly and convenient to assemble, but also has a simple overall structure and reliable function.
