In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is as follows: a kind of telescopic crossbeam, comprise supporting mechanism and drive link, described supporting mechanism and drive link are parallel to each other, described supporting mechanism comprises the first outer cross bar, the second outer cross bar and middle transverse rod, the two ends of described middle transverse rod respectively cross bar outer with first are detachably fixedly connected with one end of the second outer cross bar, and the end of described middle transverse rod can be moved on the length direction of the first outer cross bar and the second outer cross bar; Described drive link comprises the first drive link and the second drive link, and described first drive link is detachably fixedly connected with the second drive link, and described second drive link can move relative to the first drive link along the length direction of drive link.
Further, described first outer cross bar and the second outer cross bar are provided with elongated hole, and the two ends of described middle transverse rod are provided with connecting hole.
Further, the cross section of described second drive link is polygonized structure, and described first drive link is hollow structure, and the shape of this first drive link internal cavities and the shape of the second drive link adapt.
Further, one end that described first drive link is connected with the second drive link is provided with screwed hole near the position of end, and this screwed hole communicates with the internal cavities of the first drive link.
Telescopic crossbeam of the present utility model, include supporting mechanism and drive link, wherein supporting mechanism comprises the first outer cross bar, the outer cross bar of Second Year and middle transverse rod, and the two ends of middle transverse rod respectively the outer cross bar of cross bar outer with first and Second Year be detachably fixedly connected with, the end of middle transverse rod can be moved on the length direction of the first outer cross bar and Second Year cross bar outward; Wherein drive link comprises the first drive link and the second drive link, and described first drive link is detachably fixedly connected with the second drive link, and described second drive link can move relative to the first drive link along the length direction of drive link.The crossbeam of this structure is scalable, can regulate arbitrarily, in process of production according to the desktop of different size, can crossbeam be produced in batches, and not consider the specification of same table, uniform specification, produce and all decrease with management cost, and can not cause unsalable because of the problem of specification; Because this telescopic crossbeam is detachably fixedly connected with, transport and installation are all more for convenience.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the telescopic crossbeam to the present embodiment is described in further detail.
Figure 1 shows that a kind of crossbeam of same table and the structural representation of elevating mechanism, wherein a pair elevating mechanism 10 symmetrically and be fixedly connected with respectively with the two ends of crossbeam 40, and the driving mechanism 20 be elevated for driving a pair elevating mechanism 10 is fixed on the elevating mechanism 10 of wherein side.It should be noted that, the structure of the elevating mechanism 10 in the present embodiment is identical with structure corresponding in notification number a kind of same table disclosed in the Chinese invention patent of " CN103126303B ", therefore, at this, concrete structure of elevating mechanism 10 and lifting principle are not repeated.
As improvement, the crossbeam of the present embodiment is telescopic crossbeam, and this telescopic crossbeam comprises supporting mechanism 40 and drive link 30, and above-mentioned supporting mechanism 40 and drive link 30 are parallel to each other.As shown in Figure 2 and Figure 3, supporting mechanism 40 in the present embodiment comprises the first outer cross bar 42, second outer cross bar 45 and middle transverse rod 41, wherein the two ends of middle transverse rod 41 respectively cross bar 42 outer with first be detachably fixedly connected with one end of the second outer cross bar 45, and the end of middle transverse rod 41 can be moved on the length direction of the first outer cross bar 42 and the second outer cross bar 45.Specific to the present embodiment, as shown in Figure 3, the first outer cross bar 42 and the second outer cross bar 45 are provided with elongated hole 43, are provided with connecting hole 44 at the two ends of middle transverse rod 41.When mounted, by bolt or pin through connecting hole 44 and elongated hole 43, middle transverse rod 41 and the first outer cross bar 42 or the second outer cross bar 45 are fixed together.Its bolt or pin can move in elongated hole 43, select suitable position carrying out fastening, thus adapt to the desktop of different size.
