Description

Full sheet metal formula is decontroled single folding bed automatically

Affiliated field: the utility model relates to a kind of full sheet metal formula and decontrols single folding bed automatically.

Background technology: present folding bed poor stability, volume after folding is big, weight is big, takies the storage area, and carrying is also inconvenient.

Summary of the invention: the purpose of this utility model provides a kind of order of the present utility model and provides the single folding bed of the automatic relieving of full sheet metal formula little, conveniently moving that takes up room.The purpose of this utility model realizes by following structure: the utility model is that a kind of full sheet metal formula is decontroled single folding bed automatically, bed board constitutes by two groups of veneers are hinged, every group of veneer has two flaps to be hinged on the column of both sides, have vertical slideway on the column, umbrella stull is installed in the slideway, the umbrella stull other end is hinged on two flaps, auxiliary runing rest is coaxial with the main support main shaft, the flap of auxiliary runing rest is sleeved on the main shaft and has the dress lifting spring, bumps pearl and is installed on the auxiliary runing rest.The utility model is a kind of product for civilian use, adopts the punching press of steel plate mould fully, and local welding and riveted joint form, and bed surface has four block plates, main support, auxiliary runing rest, umbrella shape spreader are arranged, guides wheel into, bumps pearl, assembly formation such as automatic locking.The utility model advantage is obvious, whole stiffness is strong, simple in structure, volume is little, in light weight, conveniently moving, as folding simple, practical, safe and reliable, the scope of application is wide, to be applicable to enterprises and institutions, school, family, a first-selected product to be provided in order improving the people's livelihood.The utility model is created a bigger living space, improves people's quality of life.The utility model operation principle: when folding bed is opened, click the automatic locking switch, switch motion, main support umbrella shape spring rises, and two main supports bottoms, guides wheel into and extends, and umbrella shape spring rising maximum actuation rises to 120 degree, turn to by the auxiliary stand spring, scroll wheel action 90 rises to 180 with bed surface, is locked by umbrella stull, plug locking 180 in the middle of the bed surface, when preventing the folding bed translation, produce hogging moment, bed is set level and can be used.When folding, bed surface is erected, two auxiliary runing rests are moved on the main support, bump pearl and run into, and hold past one of main support handle and draw, and automatic locking is locked, and the bed surface cutting knife will bump the pearl incision simultaneously, wait for next time and open automatically.

The specific embodiment:

The utility model as shown in Figure 1 is that a kind of full sheet metal formula is decontroled single folding bed automatically, bed board constitutes by two groups of veneers are hinged, every group of veneer is hinged on the column 2 of both sides by two flaps 1, have vertical slideway 3 on the column 2, as shown in Figure 2, umbrella stull 4 is installed in the slideway 3, umbrella stull 4 other ends are hinged on two flaps 1, as shown in Figure 3, auxiliary runing rest 5 main shafts are coaxial with main support main shaft 6, the flap of auxiliary runing rest 5 is sleeved on the main shaft 6 and has dress lifting spring 7, bumps pearl 8 and is installed on the auxiliary runing rest 5.

As shown in Figure 4, coaxial Φ 8 main shafts and the umbellate form support shift(ing) ring put on of major-minor support, rising spring 7 is installed in the main shaft bottom, install in the main shaft pipe box and turn to spring 8, jump ring is installed at the main shaft two ends, and shift(ing) ring is at the main support crossbeam fixed bed face of locking, main support is two, connect umbellate form bed surface four points of connection, bolt device in the middle of installing has roller 9 on the auxiliary stand.

When the full sheet metal formula of processing is decontroled single folding bed automatically, at first to design each several part size and ratio, drawing scale is 1: 10, to make mould then, with four bed panel, main support and auxiliary runing rest punch forming, bed panel stamps out umbrella stull and cutting knife tie point, roll over 90 knuckles, flanging, accessory is processed in boring, other accessory moves wheel, scroll wheel, guide wheel into, the rising spring, turn to spring, need supporting outer processing, assemble main support after the processing, guide wheel into, moving wheel installs, auxiliary stand, scroll wheel is installed, bump pearl, automatic locking, handle welding or riveted joint are installed, and auxiliary stand is enclosed within on the main support, Φ 8 axis and rising frame are installed, rising spring and turn to four bed boards of spring riveted joint connects the umbrella shape lifting device, middle bolt device oil spout lacquer, the plastic packets leg, installation is opened during use, decontrols to get final product.Points for attention, youngster is heavy should not to be folded.
