Abstract

The utility model discloses a folding rack of four vertical poles, which comprises two pairs of upright poles in opposite arrangement, wherein one or more folding bracket is provided at corresponding positions on each pair of upright poles. The utility model is characterized in that: the folding bracket consists of two link frames, and the two link frames are articulated; the other end of each link frame is respectively installed in a movable manner on the two upright poles, and the two pairs of upright poles are connected by link boards provided on the folding bracket. The utility model has a simple structure, and in practical use, the rack can be folded by pulling the upright poles to move inwards so that both ends of the link frames of the folding bracket spin respectively around a rotation axis and an articulated axis, thus can easily be used; besides, the utility model takes small space and can easily be assembled and disassembled.

Description

Four column combination vertical folding framves

Technical field

The utility model relates to a kind of folding stand, particularly a kind of four post vertical folding framves that use on furniture.

Background technology

For reducing furniture in space shared under non-working condition, the table frame of general furniture such as desk adopts the folding stand structure usually, and the folding stand of this structure reaches folding purpose by the central shaft that is provided with in the middle.The folding stand of this structure only is applicable to the desk of single sheathing, and the desk with multilayer panel is unsuitable for using, cause family and the office occasion in widely used desk with multilayer panel can not fold, thereby its occupation space is big under non-working condition, and causes the inconvenience of conveying in sections.For addressing this problem, a kind of folding stand that applies to have the desk of multilayer panel has appearred now, this folding stand comprises horizontal folding support and vertical folding support, the centre of horizontal folding support and vertical folding support is hinged by hinge respectively, the two ends of horizontal folding support are hinged with column by the hinge hinge, and the two ends of vertical folding support are connected on the column by hinge.Yet this folding stand complex structure, operation is more loaded down with trivial details when folding.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, four post vertical folding framves easy and simple to handle when little, folding take up room.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of four post vertical folding framves, comprise two pairs of columns that are oppositely arranged, the opposite position place of every column is equipped with one or more folding rack relatively, it is characterized in that described folding rack comprises two links, hinged between two links by hinge, the other end of two links is movably arranged on respectively on two columns, links together by the connecting plate that is installed on the folding rack between two columns, on two links supporting and limiting device is installed.

As the improvement of the above-mentioned embodiment of the utility model, on the described column fixed block is installed, described link is movably arranged on the column by the turning cylinder that is arranged on the fixed block.

Preferred embodiment a kind of as the utility model, described supporting and limiting device comprises hinged with two links respectively pin-joint piece, on the connecting axle between two pin-joint pieces and the link torsion spring is installed, two pin-joint pieces can rotate 90 ° relative to two links, can make two hinge plates put up plumbness with being connected, hinged between two pin-joint pieces by jointed shaft.

The beneficial effects of the utility model are: the utility model is simple in structure, and the pulling column need only be moved inward when folding, thereby make rotate respectively moving axis and jointed shaft of the two ends of the link of folding rack rotate and get final product, thereby easy and simple to handle; And its occupation space is less, and installing/dismounting is all very convenient.

Fig. 2 is the schematic perspective view of the utility model folding process;

Fig. 3 is the schematic perspective view of folding rack user mode;

Fig. 4 is the schematic perspective view of folding rack when folding;

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of four post vertical folding framves disclosed in the utility model comprise two pairs of columns that are oppositely arranged 1, and the opposite position place of every column 1 is equipped with two folding racks 2 relatively.

With reference to Fig. 3, Fig. 4, Fig. 5, folding rack 2 comprises two links 3, two links 3 are hinged together by hinge, can relatively rotate between two links, end at link 3 is provided with fixed block 5 by turning cylinder 4, fixed block 5 is fixedly mounted on the column 1, thereby by fixed block 5 two links and column is linked together, and can rotate moving axis 4 of link 3 rotates.

On two links supporting and limiting device is installed, supporting and limiting device is used to prevent that two links 3 of folding rack 2 from use relatively rotating, to keep the utility model stability in use.

As shown in the figure, supporting and limiting device is by forming with the hinged pin-joint piece 8 of two links 3 respectively, torsion spring 9, two pin-joint pieces are installed on the connecting axle between two pin-joint pieces and the link can rotate 90 °, and can make two hinge plates put up plumbness with being connected relative to two links.Hinged by jointed shaft 6 between two pin-joint pieces 8, when two links 3 were in same straight line, two pin-joint pieces 8 can rotate around the link hinged with it respectively, and two pin-joint pieces 8 also can rotate with two links simultaneously.

Link together by the connecting plate 7 that is installed on the folding rack 2 between two columns 1, thereby form four post vertical folding framves disclosed in the utility model.

Folding stand in use, two pin-joint pieces 8 under the effect of torsion spring 9 with link 3 in vertical state, relatively rotate thereby limit between two links 3, to keep the utility model stability in use.

When the utility model folds, two pin-joint pieces of support limit effect have at first been rotated, make itself and two links be in same plane, at this moment inwardly spur column, two links relatively rotate, simultaneously the other end of the two links moving axis that rotates respectively rotates, thereby two links are stacked together mutually, reaches folding purpose.

The above only is a preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it, and the utility model is not only applicable to have the desk of two-layer panel, also is applicable to simultaneously to have one deck or two-layer desk with top panel.So long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
