Abstract

The utility model provides an iron art bed capable of automatically adjusting a backrest. The iron art bed is a secondary framework made of a rectangular steel pipe, wherein the framework is divided into front and back parts which are connected through a secondary hinge; an arenga engleri mattress is paved on the framework; the front half part of the framework is fixedly and horizontally placed on a long bed lever; the rear half part of the framework can be hoisted around the hinge; each one of vertical steel pipes at the two sides of the rear half part of the framework is internally connected with the other small rectangular steel pipe and can slide; the top end of each one of the two small rectangular steel pipes is connected with an angle-square-shaped slide block, a group of groove small wheels and a chain; each one of the two chains is fixed at the side edge of a large chain wheel through a small chain wheel; the two large chain wheels are respectively connected with double output shafts of a worm wheel speed reducing box through a long shaft and a shaft coupler and are driven by a motor; and a two-directional switch is arranged at the side edge of the bed so that the rear half part of a bed plate can be automatically hoisted together with the mattress to form one bed backrest for people to lean, and the front half part of the framework of the bed plate can be descended to be leveled for the people to lie down.

Description

A kind of backrest is regulated iron skill bed automatically

Affiliated technical field

The utility model relates to a kind of steel-pipe furniture---iron skill bed.

Background technology

At present, the bed-rest of the Household iron skill bed on market has various styles, but is all changeless, sees that in bed TV just must use several headrests if lean to, and is not too convenient; Although in hospital, general patient's iron bed bed board can tiltedly be dug and make backrest and use, the bed board that it is the auxiliary lever mechanism that relies on bed lower, shake the activity of propping up by the handle after bed is realized, needs other people help to be accomplished.

Summary of the invention

For defects, the iron skill bed that the utility model provides is with a kind of electric device, starting it makes the latter half framework of bed board become an oblique angle with the bed board horizontal plane together with automatic rise of mattress, can automatically form easily a bed-rest, lean to for the people and see in bed TV, the used time can not fall automatically yet, flush with the first half framework of bed board, lie down for the people and fall asleep.

the technical scheme that the utility model adopts is: the bed board of iron skill bed is a sub-frame made from rectangular steel pipe, framework is made by horizontal steel pipe and perpendicular steel-pipe welding, pull into netted with known spring steel wire in the middle of framework, the above is spreading the Palm fibre mattress of 30-50cm, this bed board framework is divided in two parts, the first half framework is slightly long than the latter half framework, they rely on a secondary hinge to be connected, the first half framework fixedly lies on long bed thick stick, the latter half framework can rise around hinge, the perpendicular steel pipe inboard on latter half framework both sides respectively is fixed wtih another root rectangular steel pipe, each fastening rectangle copper hoop of the inwall on this rectangular steel pipe top, in rectangle copper hoop, each plug-in mounting a little rectangular steel pipe, the bottom of two little rectangular steel pipes is filling pulley, little rectangular steel pipe can be slided in the rectangular steel pipe of latter half framework both sides easily, the top of these two little rectangular steel pipes is being flexibly connected respectively an angle-square-shaped slide block, one secondary groove steamboat all is installed on two angle-square-shaped slide blocks, they are inlaid in the elongated slot of two column rear sides of iron skill bed, the energy scroll-up/down, two angle-square-shaped slide blocks are connecting respectively a chain, the other end of these two chains is respectively by after being arranged on the minor sprocket in column, be fixed on respectively the tangent line side of a hinge wheel, these two hinge wheel centers are fixed wtih respectively the below that a major axis is arranged on iron skill bed, one end of these two major axis is contained in respectively in the bearing at chain wheel cover center, the other end is connected with two shafts of a worm wheel gearbox by a shaft coupling respectively, the worm screw input of worm wheel gearbox is connected with a motor rotor shaft by another shaft coupling, motor and worm wheel gearbox are fixedly mounted on a base support of centre, iron skill bed below, start the two-direction switch that is arranged on bed board latter half framework one side, can drive the positive and negative rotation of two shafts of worm wheel gearbox, and pass to the hinge wheel that above-mentioned major axis drives its two ends and synchronously do positive and negative rotation, then driving two chains pulls two angle-square-shaped slide blocks to do upper and lower displacement in elongated slot, simultaneously just pull two little rectangular steel pipes at the rectangle steel inner telescoping tube of latter half framework two inboards, and drive the rise of latter half framework or fall, make the latter half framework of iron skill bed bed board become an oblique angle with the bed board horizontal plane together with automatic rise of the latter half of Palm fibre mattress, form a bed-rest, also can automatically fall, flush with the first half framework of bed board, lie down for the people and fall asleep, this has just reached the purpose of this utility model.

In addition, when two chains pull two angle-square-shaped slide blocks to move up in elongated slot, one of them elongated slot top is filling a limit switch, can automatically cut off electric current and make the motor stall when an angle-square-shaped slide block touches its button, has guaranteed that chain can not broken.

Two above-mentioned chains, two secondary hinge wheels and minor sprocket transmission device also can adopt two steel wires, two secondary large wire wheels and little wire wheel as transmission device, can reach the purpose of this utility model equally.

The beneficial effects of the utility model are: increased new function for Household iron skill bed, facilitated people to lean to the demand of seeing in bed TV, lie and lean on freely.
