Abstract

The utility model relates to a folding rectangular table which comprises a folding tabletop and table legs which are composed of equilateral diagonal rod elevations and two groups of two crossed diagonal rods, wherein, the diagonal rod elevations are formed by hinging a V-shaped diagonal rod group and an inverted V-shaped diagonal rod group, the ends of the two diagonal rods of the V-shaped diagonal rod group are hinged with lower connecting plates, and the ends of the two diagonal rods of the inverted V-shaped diagonal rod group are hinged with upper connecting plates. Two sliding bushes capable of counterrotating are fixed on the upper connecting plates, a transverse rod with an arresting pin at one end is sheathed on each sliding bush, and the other ends of the two transverse rods are respectively hinged with both ends of the V-shaped diagonal rods. The two groups of two crossed diagonal rods are respectively hinged with the close end parts of the diagonal rods which are included in the V-shaped diagonal rod groups and the inverted V-shaped diagonal rod groups of the equilateral diagonal rod elevations. Because the cross combination of double V-shaped diagonal rod groups are adopted, the supporting scope of the both side diagonal rod elevations is two times larger than end part elevations, a rectangle tabletop can be stably supported with consecutive operation, and the operation of spread and fold is as simple as that of a square table.

Description

Collapsible rectangular table

Technical field:

The utility model belongs to the small stores field, particularly a kind of portable and collapsible rectangular table.

Background technology:

Patent gazette is put down in writing the patent that a publication number is a CN2426698 folding table by name, this patent provides a kind of columned folding table that can be folded into, its structure comprises folding bar desktop 4 and table pin, the table pin is made up of four groups of braces that intersect in twos 1, every group brace 1 passes through last with the end of adjacent set brace 1, leftover bits and pieces dish 3 location, wherein riveted a support bar 2 respectively at two brace infalls of symmetry group, be fixed with the counterrotating sliding sleeve of two energy on the other end of support bar 2, all be with the cross bar of an end band spacer pin on each sliding sleeve, this cross bar is positioned on the same group the upper foot disk contiguous block by rivet.This utility model patent has compactness simple for structure, good integrity, and it is little that folding plays volume; Holding capacity is big, and is reliable and stable, characteristics easy to use.But this folding table is supported the restriction of a pin can only the squarely structure, if desktop is extended to rectangle the unsettled defective of support is arranged promptly.

Summary of the invention:

The purpose of this utility model is a kind of collapsible rectangular table with rectangular structure desk and supporting ﹠ stablizing of design.

Technical solutions of the utility model are achieved in that a kind of collapsible rectangular table, comprise folding desktop and table pin, the table pin is by bilateral symmetry brace facade and connect two group two of two brace facades and intersect brace and form, it is characterized in that the brace facade is hinged on down " V " shape brace group of knot dish and two brace ends by two brace ends and is hinged on and falls hinged the forming of " V " shape brace group on the knot dish, and the two brace ends that keep going up knot dish and " V " shape brace group are on the same horizontal plane, be fixed with the counterrotating sliding sleeve of two energy on the last knot dish, all be with the cross bar of an end band spacer pin on each sliding sleeve, this two cross bars other end is hinged with the both ends of " V " shape brace respectively, and two group two intersects the brace group and be hinged on " V " shape brace group of bilateral symmetry brace facade respectively and fall on the brace close end of " V " shape brace group.Owing to adopt two " V " shape brace group combined crosswise, the scope that both sides brace facade is supported doubles the end facade, but stable support plays a rectangle desktop, and two " V " shape brace group can rise along the pin joint folding of knot dish up and down, two groups intersect the brace groups and not only play and support and the brace facade effect of related both sides, and also can make the synchronous folding in both sides during folding.

The utlity model has novelly, design ingeniously, by the combination of two " V " shape brace group, it is big not only to support scope, can support the rectangle desktop, and stable related with action, opens the same simple with cubic with the folding operation.

Description of drawings:

Below in conjunction with concrete legend the utility model is described further:

The specific embodiment:

With reference to Fig. 2, Fig. 3 and Fig. 4, collapsible rectangular table, comprise folding desktop 4 and table pin, the table pin is by bilateral symmetry brace facade and connect two group two of two brace facades and intersect brace 1 and form, wherein the brace facade is hinged on down " V " shape brace group 51 of knot dish 5 and two brace ends by two brace ends and is hinged on and falls " V " shape brace group 61 hinged forming on the knot dish 6, and the two brace ends that keep going up knot dish 6 and " V " shape brace group 51 are on the same horizontal plane, be fixed with the counterrotating sliding sleeve 7 of two energy on the last knot dish 6, all be with the cross bar 8 of an end band spacer pin 81 on each sliding sleeve 7, after being opened, can strain folding table leg, this two cross bars other end is hinged with the both ends of " V " shape brace respectively, 51 liang of brace ends of " V " shape brace group upper fin rises during folding, and cross bar 8 skids off toward sliding sleeve 7 one ends of upper foot disk 61 gradually, two group two intersects brace group 1 and is hinged on " V " shape brace group 51 of bilateral symmetry brace facade respectively and falls on the brace close end of " V " shape brace group 61, bilateral symmetry brace facade is associated, and can give " V " shape brace group 61 with the stressed conduction of " V " shape brace group 51, can alleviate pressure to two groups of " V " shape brace group close ends, rod member is selectable thinner or littler, saves material.Two brace end close end cambers in " V " shape brace group 51 of bilateral symmetry brace facade are turned up up, make itself and cross bar 8 hinged more convenient, and the pressure component of cross bar 8 more is directly passed to two and intersects braces 1.

In addition, 5 hinged one or four connection rod set 9 of knot dish 6 and following knot dish on bilateral symmetry brace facade play and strengthen related bilateral symmetry brace facade, and open or folding smoothness more.

Claims

1, a kind of collapsible rectangular table, comprise folding desktop and table pin, the table pin is by bilateral symmetry brace facade and connect two group two of two brace facades and intersect brace and form, it is characterized in that the brace facade is hinged on down " V " shape brace group of knot dish and two brace ends by two brace ends and is hinged on and falls hinged the forming of " V " shape brace group on the knot dish, and the two brace ends that keep going up knot dish and " V " shape brace group are on the same horizontal plane, be fixed with the counterrotating sliding sleeve of two energy on the last knot dish, all be with the cross bar of an end band spacer pin on each sliding sleeve, this two cross bars other end is hinged with the both ends of " V " shape brace respectively, and two group two intersects the brace group and be hinged on " V " shape brace group of bilateral symmetry brace facade respectively and fall on the brace close end of " V " shape brace group.
