Detailed ways

The utility model mainly provides a combined supporting truss. Referring to the first to third figures, the supporting truss (10) of the present utility model mainly includes at least three sets of relative upper pivot seats (12) and lower pivot seats. (14) (as shown in the figure, four groups are used as an example for illustration), each upper pivot seat (12) is pivotally provided with a pivot rod (11) that is pivotally connected to the adjacent lower pivot seat (14) , two intersecting pivots (11) are formed between two groups of adjacent upper and lower pivot seats (12, 14), and the two intersecting pivots (11) are also pivotally connected to each other. The utility model The key point of the design is that each group of relative upper and lower pivot seats (12, 14) is provided with a telescopic support rod, which is sleeved by an inner sleeve rod (15) and an outer sleeve (16). Composition, an inner sleeve rod (15) is fixed at the bottom of each upper pivot seat (12), and an outer sleeve for the relative inner sleeve rod (15) to penetrate is fixed at the top surface of each lower pivot seat (14) pipe (16), and the inner sleeve rod (15) and the outer sleeve (16) can move relatively telescopically, and hoof pads (17) are provided at the bottoms of each lower pivot seat (14) in addition. the

When unfolding, directly pull the two adjacent outer sleeves (16) to move relatively outwards from the state shown in the third figure, so that all the upper pivot seats (12) can be ) and the lower pivot seats (14) are relatively outwardly moved, and at the same time let the inner sleeve rods (15) on each upper pivot seats (12) relatively extend into the outer casing (16), so that the upper pivot seats (12) are relatively The lower pivot seats (14) approach, and when each upper pivot seat (12) moves to contact with the top end of the outer sleeve (16), it reaches the fully deployed position. At this time, the utility model can utilize the jacking of the outer sleeve (16) to position each upper pivot seat (12), and then allow the support truss (10) to be deployed and positioned to the use position, and then assembled on the support truss (10) A desktop, a platform board, etc. are provided, so that the support truss (10) can cooperate to form items such as a table, a stage, or a chair for users to use. the

When the support truss (10) is to be folded, only two adjacent outer sleeves (16) are relatively close together, and the upper and lower pivot seats (12, 14) can be driven by the pivot rod (11). ) relatively close to fold, and allow the inner sleeve rod (15) to relatively stretch out the outer sleeve (16), so as to facilitate the storage and transportation of the support truss (10). the

In addition, in order to facilitate the assembly of the desktop panel (20), a boss (13) can be protruded from each upper pivot seat (12), as shown in Figure 5, by connecting the bosses (13) and The connecting holes of the desktop platform cooperate with each other, so that items such as the desktop can be assembled on the support truss (10) quickly, conveniently and stably, or separated from the support truss (10). the

The supporting truss (10) of the utility model is mainly composed of at least three sets of relative upper and lower pivot seats (12, 14), and an inner rod (15) is fixed at the bottom of each upper pivot seat (12). And each lower pivot base (14) is provided with an outer sleeve (16) that can be penetrated by the relative inner sleeve rod (15), and each upper pivot base (12) is pivotally provided with a pivot connection to the adjacent The pivot bar (11) of the lower pivot seat (14), and the two intersecting pivot bars (11) are also pivoted to each other, so that the supporting truss (10) can be expanded and retracted through the linkage of the pivot bars (11). combined, and after the support truss (10) is unfolded, each upper pivot seat (12) is supported on the outer casing (16), thereby allowing the support truss (10) to carry a greater load, and can achieve The purpose of improving the use efficiency and practicality of the support truss (10). the

In addition, as shown in Figures 5-7, the assembly of each upper pivot seat (12) and the desktop plate (20) is equipped with a quick assembly and disassembly mechanism, so that the components can be neatly folded and convenient for transportation and storage. Referring to Fig. 4, the desktop flat plate (20) is composed of a plurality of sheet group units (21), and each group of sheet units (21) is assembled by a plurality of strip-shaped forming plates (26), and the parallel strip-shaped forming plates (26) two ends are combined with groove shape connection block (24). The boss (13) of the upper pivot seat passes through the perforation (25) of the L-shaped combination bar (22), and then is strung into the notch groove (23) below the groove-shaped connecting block (24) of the grouping unit, and the boss The side grooves (131) can fasten the panel unit (21), so that the supporting truss (10) and the table top plate (20) can be fastened. the

In summary, the utility model can indeed improve the deficiencies and lacks in the structure of the conventional combined support truss, and provide a stronger support force for the support truss by the telescopic support rod, and improve the function of quick assembly and disassembly. The seat is equipped with a quick assembly and disassembly mechanism. The protruding column of the upper pivot of this mechanism passes through the perforation of the L-shaped combination bar, and then is strung into the notch groove under the groove-shaped connecting block of the assembling unit, so as to complete the fastening of the supporting truss and the desktop plate. It is a very progressive masterpiece. What is shown in the above description and drawings is only a preferred embodiment of the present utility model. Of course, simple modifications or changes can be made in other structural parts, as long as it does not exceed The categories defined by the scope of the appended application model should all belong to the protection scope of the present utility model. the
