Description

A kind of handrail of Collapsible support lever

Technical field

Power-assisted handrail is the utility model is related to, is especially mounted on vehicle or toilet to aid in old man to play seat A kind of handrail of Collapsible support lever.

Background technology

China starts to step into aging population society, and increasing the elderly is handicapped, it is necessary to the power-assisted branch of handrail Support is sat to rise；There is setting to specialize in the love seat to the elderly on existing public transit vehicle, do not set on these love seats Handrail is put, the elderly is played seat on these love seats very painstaking；For another example, existing armrest for closestool be mostly fixedly mounted and It can not store, space-consuming, and the width between the height of handrail and handrail is fixed, for some fat people, Gu Lower pressure suffered by the handrail being scheduled on toilet is born by toilet support entirely, and the time one easily causes toilet basis pine long Move and damage, and hand-held upper setting support bar is directly fixed with ground, and installing space is taken significantly.

Utility model content

To solve the above problems, the utility model is directed to a kind of handrail of Collapsible support lever, it is mountable to public affairs Hand on vehicle seat position or on toilet, the width at handle height or interval is can adjust, so that different heights, fat or thin the elderly make With, and excessive use space will not be taken after handle storage folding.

For the above-mentioned purpose, the utility model provides a kind of handrail of Collapsible support lever, including a supporting plate and fixation Two free bearings at supporting plate or so end, be hinged on each free bearing one can front and rear rotation swing rod, it is characterised in that：Each swing rod front end Connect a support bar, the support bar is by being vertically fixed in the first pole of swing rod front end and being hinged on the of the first pole bottom Two poles are formed, each handle of first pole top movable grafting one；Be slidably connected on each free bearing one can move left and right with swing rod Fixed pole, fixed pole rear end are connected with swing rod turning end, and fixed pole front end and the second pole are movably hinged by a connecting rod；Described pendulum Bar, support bar, connecting rod and fixed pole are be hinged to form plane double leval jib foldable structure.

Be hinged on described free bearing one can front and rear rotation rotating shaft part, two parallel first locking bars of swing rod rear end and rotating shaft The plug of part axially position coordinates；A slide-bar parallel with rotating shaft part, slide-bar and free bearing bottom are fixed among the fixed pole side of rotation stop Plug is slided to coordinate；To realize the Plug Action of the first locking bar and rotating shaft part and the Plug Action synchronous interaction of slide-bar and free bearing, Allow to form plane double leval jib foldable structure integrally in supporting plate both sides or so by swing rod, support bar, connecting rod and fixed pole are be hinged Move a certain distance, to adjust the spacing of two handles, make fat or thin the elderly that the utility model all can be used.

Rear is pushed up on described free bearing and is provided with an axle sleeve, is provided with a neck in front of free bearing top, rotating shaft part is provided with one and axle The pivot joint pipe being rotatably assorted and one is covered to insert pivot joint respectively with the card bit pipe of neck clamping matching, described two first locking bars and manage Connected with card bit pipe；Described free bearing bottom is provided with a slot parallel with rotating shaft part, and described slide-bar is slidably matched with slot； Two first locking bars and pivot joint pipe, the Plug Action of card bit pipe and slide-bar with the Plug Action of slot are linkages and synchronous, So that the be hinged plane double leval jib foldable structure that forms of swing rod, support bar, connecting rod and fixed pole can be moved left and right integrally at supporting plate end, To adjust the spacing of two two handles.

Described fixed pole rear hole is hinged on swing rod rear end by the first hinge, the first described pole bottom and second The first of bar top is reamed and is hinged by the second hinge, on the second pole before the second fraising of the first fraising lower section and connecting rod End circular hole is hinged by the 3rd hinge, and rod rear end circular hole is hinged with fixed pole front aperture by the 4th hinge；Make swing rod, support Bar, connecting rod and fixed pole are be hinged to form plane double leval jib foldable structure, when handle turns over storage, swing rod rotation backward, even Upwards backward during rotation, connecting rod front end is pulled back the second pole by connecting rod in uphill process bar, most finally swing rod, prop up Strut and connecting rod are folding, and are substantially reduced the space shared by the utility model.

An embedding hole for being used to install lock, embedding hole both sides and pivot joint pipe and card bit pipe are provided among described rotating shaft part head Communicate；Button cover for seat enters in embedding hole, and the bottom plate of embedding bottom hole portion insertion one and the bottom clamping of button seat, button is inserted in button seat in a pressing way In, the spring of top pressure one between button and bottom plate；The opposite side of two described first locking bars is provided with some locked grooves, button two Side blocks locked groove and pins the first locking bar, and pressing button can make button exit locked groove to unlock the first locking bar；Pass through this structure side Formula realizes that the first locking bar inserts position and lock in pivot joint pipe and card bit pipe with different length, realizes the regulation of width between two swing rods Locking or unblock, realize the regulation of two handle spacing indirectly.

Described handle bottom is provided with the second locking bar with the first pole plug location fit；Pass through the second locking bar insertion the The difference of the depth of one pole, handle is can adjust apart from the height on ground, makes the elderly of different heights that this practicality all can be used It is new.

The beneficial effects of the utility model are：

1. compared with traditional handrail, the width between the height and handle of handle of the present utility model can adjust, with Meet that different heights and fat or thin the elderly use；

2. support bar can fold with storage is turned over after handle, the utility model is avoided to take excessive sky under non-working condition Between and influence other people activity spaces.
