Abstract

The utility model relates to a universal folding table frame, which comprises a long pipe member 1 and a short pipe member 3 which are connected by a pin shaft 2. A U-shaped pipe member 4 is hinged with the upper end of the short pipe member 3 through a pin shaft 5, and the U-shaped pipe member 4 is provided with limiting stop iron 6. The top ends of the long pipe member 1 and the U-shaped pipe member 4 are provided with angle iron 7 connected with a table top, and the lower parts of the long pipe member and the short pipe member are both fixedly connected with horizontal pipes 9. The utility model is characterized in that the lower ends of the long pipe member and the short pipe member are respectively provided with a universal wheel 10, and the lower part of the short pipe member 3 is provided with an angle regulator 12. The folding table frame has the advantages of convenient movement and labor saving. Besides, the included angle between the table top and the ground surface can be regulated, and thus, the utility model can be used as an easel, a music frame, etc.

Description

A kind of universal folding table frame

The utility model belongs to people's daily living article, and particularly the folding table frame to the existing usefulness of having dinner improves.

Existing folding table frame is to rotate around horizontal bearing pin by long pipe fittings, short pipe fitting, U type pipe fitting to open or close up, close up in the process opening, the rigid wiping of whole strokes ground, bottom, need when mobile that body is unsettled mentions with whole table, so heavy effort of operation, the center of gravity unreasonable structure, Chang Yi topples over and breaks a body.

The purpose of this utility model is a kind of simple structure of development, and rapid operation, steadily of centre of gravity can be reconciled the folding table frame of desktop angle again.

Narrate structure of the present utility model below in conjunction with accompanying drawing.

A kind of universal folding table frame, it comprises long pipe fittings 1 and the short part pipe 3 that is linked by bearing pin 2, by bearing pin 5 upper end of U type pipe fitting 4 with short pipe fitting 3 is hinged, limited stopping iron 6 on the U type pipe fitting 4, top at long pipe fittings 1 and U type pipe fitting 4 is connected the angle bar 7 that has screw by bearing pin 8, and angle bar 7 is used for linking to each other with desktop.Affixed transverse tube 9 is arranged at the bottom of two long pipe fittingses 1 and two short pipe fittings 3, it is characterized in that respectively being equipped with universal wheel 10 in the lower end of long pipe fittings 1 and short pipe fitting 3.When the table frame got out, universal wheel 10 was outwards cast aside, and when the table frame closed up, the axostylus axostyle of universal wheel 10 was perpendicular to ground.

In order to make a frame reconcile the gradient of desktop, pass through bearing pin 11 setting angle adjusters 12 in the bottom of short pipe fitting 3, the gap that matches with the transverse tube 9 of long pipe fittings 1 bottom is arranged on the angle demodulator 12.Perhaps be equipped with lateral pin 13 in the bottom of long pipe fittings 1, the gap of angle demodulator matches with it.

About the installation method of universal wheel 10, the lower end that is welded on table leg (long and short pipe fitting) to axostylus axostyle of standing of universal wheel 10 also can be linked to each other with the table leg lower end by screw thread.The bottom of table leg can be outwardly-bent parallel to the ground, perhaps at one section transverse tube spare parallel to the ground of the lower end of table leg weldering, universal wheel 10 is installed on the horizontal position or transverse tube spare of table leg then.

Because this frame is equipped with angle demodulator, when on the transverse tube that the different gap on the angle demodulator is stuck in the long pipe fittings bottom or on the lateral pin 13, just the desktop adjuster can be become the desktop of different gradients such as reading desk, easel, music easel.

Because the upper table leg lower end is equipped with universal wheel, so conveniently moving is laborsaving.
