Specific embodiment

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figure 1 and Figure 2, a kind of pipe connection structure of same table, comprising: the first tube body 100, the second tube body 200, Lead screw 300 and Pipe connecting fitting 400, first tube body 100 are threaded through in second tube body 200, and the lead screw 300 is worn It is located in first tube body 100, the Pipe connecting fitting 400 is two-half structure and has inner hole, and the lead screw 300 is solid It is scheduled in the inner hole, second tube body 200 is connect with the Pipe connecting fitting 400, and the lower end of first tube body 100 The upper surface of the corresponding Pipe connecting fitting 400.

First tube body 100, end are fixedly connected with the transverse beam assembly；Preferably, the diameter of the first tube body 100 is greater than The diameter of lead screw 300, and less than the diameter of the second tube body 200, the second tube body 200 is set in outside first tube body 100, It preferably, is the relationship being arranged between the second tube body 200 and the first tube body 100, lead screw 300 is arranged in first tube body In 100；Preferably, the diameter of lead screw 300 is minimum, is threaded through in the first tube body 100.

Pipe connecting fitting 400 is two-half structure and has inner hole, and the lead screw 300 is fixed in the inner hole, Second tube body 200 is connect with the Pipe connecting fitting 400, and the lower end of first tube body 100 corresponds to the tube body and connects The upper surface of fitting 400.

Preferably, Pipe connecting fitting 400 is actually split type structure, with the portion that symmetrical two halves are detachable Part, by will form a circular hole, that is, inner hole after two parts are stitched together, inner hole can clamp lead screw 300, Namely lead screw 300 and Pipe connecting fitting 400 are fixed together, the first tube body 100 is then fixed on one with Pipe connecting fitting 400 It rises, to realize being fixedly connected between lead screw 300 and the first tube body 100.

It is worth noting that, traditional Pipe connecting fitting 400 is an integral structure herein, can not be dismantled, lead screw 300 Be fixed on connector by knot that can be undone by a pull, cause bonding strength lower, and the side of connector is screwed into screw, thus by middle pipe with Lead screw 300 links together, very troublesome in this way, and structurally, also not ingenious enough, and disassembly installation is not also square Just.

And in the present embodiment, split type structure is used, is attached using the Pipe connecting fitting 400 of two halves formula, Not only clever structure, but also convenient disassembly, connection effect are also very reliable.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, the Pipe connecting fitting 400 includes left link block 410 And right link block 420, the left link block 410 with after the right link block 420 is semi-annular shape structure and the two merges Form the circular Pipe connecting fitting 400.

Preferably, left link block 410 and right link block 420 are semi-circular shape, and the two can be stitched together, thus shape At inner hole, the Pipe connecting fitting 400 of this structure is different from traditional integral structure, and dismounting is more convenient, and can Very reliably lead screw 300 is fixed.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, the left link block 410 and the right link block Be provided with the first connecting pin 430 on 420, offer the first connecting hole 310 on the lead screw 300, the left link block 410 with And the right link block 420 clamps the lead screw 300 from the two sides of the lead screw 300, and first connecting pin 430 is worn In first connecting hole 310.

Preferably, left and right link block 420 has on the position of its intrados due to being semicircular ring assembling structure towards circle First connecting pin 430 in heart direction, left and right link block 420 can clamp lead screw 300 from the left and right sides, while pass through the first connection Pin 430 is fixed together with the first connecting hole 310, lead screw 300 efficiently easily can be securely attached to tube body in this way In the inner hole of connector 400.
