Abstract

The utility model relates to a stabilizing structure of a handrail lifting device. The stabilizing structure comprises a sliding part, wherein the sliding part is arranged below a handrail and penetrates through a penetration support part of a handrail bracket so as to be positioned in a vertical sliding manner; a continuous cruciate positioning groove and a long groove hole are respectively formed on two opposite side surfaces of the penetration support part; a guide hole is formed on the side surface of the sliding part corresponding to the long groove hole; a button of which the inner side props against a positioning element is buckled on the other side of the sliding part; a cruciate clamping part and a penetration guide part are arranged on the positioning element, notches are formed on two sides of the cruciate clamping part, and the penetration guide part can both penetrate a propping element and the guide hole; subsequently, a spring for ejecting the positioning element together with the button is arranged between the propping element and an inner side end of the clamping part, so that the handrail can be positioned after being lifted and adjusted to a desired height; and meanwhile, due to the guidance of the guide hole, the positioning element does not tilt or offset, so that the handrail can be adjusted and operated more smoothly and does not slip off or suddenly fall off after being clamped.

Description

The rock-steady structure of handrail lowering or hoisting gear

Technical field

The utility model relates to the adjustable arm height and control the setting element of location, is to wear to close in a guide hole and guided displacement, even allow setting element be subject to the problem that crooked skew also can not occur to lower compression greater weight.

Background technology

Constructional device about the lifting of capable of regulating Chair armrest, such as No. 100208264 " armrest height adjusting device " patent of TaiWan, China, it mainly is one to be installed on the armrest support of chair tool, if one can more than, the handrail of lower slider and location, wherein this armrest support establish one upwards vertical stretch to wear close support sector, and the place, side of closing support sector is worn in order, from top to bottom be provided with continuous criss-cross locating slot, and this continuous locating slot comprises a slideway, and the block groove that is positioned at slideway one side or place, both sides, then be provided with down on this handrail stretch and with wear the cunning of closing support sector's fit and close section, and make this cunning close the section side being arranged with one corresponding to the book office of locating slot and holding groove, and hold groove at this and be embedded one and can in this groove, slide, and being subjected to the setting element of outside elasticity pushing tow, the inboard of this setting element is convexly equipped with a guide sliding part that can slide along slideway simultaneously, and can plug together the location division with arbitrary block groove plugs together.

Enable to see through the ease of Use gimmick of pressing or discharging to setting element, just can carry out the adjustment of handrail differing heights, but because the setting element in the device is the design that class is a button-like, and side is one-body molded within it has guide sliding part and plugs together the location division, a little eccentric part between the inboard of holding groove and setting element is installed a spring simultaneously, add setting element and hold between the groove for convenient and make and assembling, have larger space; Therefore, when the operator presses setting element, when if not its point of application is positioned at the center of guide sliding part, just be very easy to cause the crooked of setting element and skew, cause outside the identical generation difficulty between setting element and the locating slot, more when the handrail behind the location be subject to arm hold up by the time the compressing of downward weight the time, cause the medial extremity of setting element crooked downwards, so that originally be fastened between together the setting element and locating slot, the phenomenon of slippage occurs, and causes handrail to understand the unexpected easy generation danger that falls down.

The utility model content

In order to improve aforementioned existing handrail when held up by by arm or pressing down strength and when suffering oppression, setting element can occur crooked and easily break away from wearing on the locating slot that closes in the support sector, the problem that causes handrail to plunk down, the utility model namely allows setting element one end be provided with to wear and closes guidance part and wear and close in the guide hole set on handrail, make and to avoid setting element because of load-bearing crooked problem to occur, and then prevent from locating the smoothness that plunks down and increase adjusting operation of back bar.

The technical scheme that its technical problem that solves the utility model adopts is: be to comprise that its both sides are respectively equipped with the armrest support that closes support sector of wearing of continuous crosswise locating slot and long slot bore, can slide and suitablely enter each corresponding position, its two sides and be respectively equipped with a cunning that is equiped with button and guide hole and close in the handrail of section, and establish that an one side has the crosswise fastening part and the setting element that relies on the button inboard, and make again the setting element other end be provided with wearing and close guidance part and wear to close in sliding and close in the guide hole of section, and then close on the guidance part sheathed one wearing of setting element and can sit its pushing tow and be located at a spring that ends on the element that supports that is resisted against the long slot bore place.

The rock-steady structure of the handrail lowering or hoisting gear that the utility model provides comprises that its both sides are respectively equipped with the armrest support that closes support sector of wearing of continuous crosswise locating slot and long slot bore, can be sliding suitablely enter the cunning that its corresponding position, side is equiped with a button and close in the handrail of section, wherein this button inboard end of being subjected to an one side to have the setting element of crosswise fastening part leans, and make set the wearing of the setting element other end close guidance part wearing to close in this cunning and close in the set guide hole of section's respective side, and closing on the guidance part sheathed one wearing of setting element can be to the spring of its pushing tow, and the other end of spring then seats in and is resisted against one on the long slot bore and supports and end on the element.

In the such scheme, this locating slot comprise a long straight slideway, with the block groove that is positioned at this slideway on one side or place, both sides consecutive intervals arranges.

In the such scheme, the fastening part of this setting element includes and consists of criss-cross guide sliding part and location division, and the place is provided with breach in the middle of the location division, both sides.

The beneficial effects of the utility model are, seeing through above-mentioned setting element of the present utility model, to be subjected to the support of guide hole set on the handrail and guiding and setting element be to be resisted against on the button and to be the design of two independent components, allow and be subjected to the setting element of weight compressing can not offset downward crooked along the long slot bore displacement, and then guarantee the steadiness of blocking between the locating slot set on setting element and the armrest support, also make simultaneously the operator no matter press on arbitrary place on the button, also can not cause the deflection of setting element, and then promote the smoothness of operation.
