[0019] The embodiment of the utility model will be further explained in detail in combination with the drawings.

[0020] The telescopic adjustable pipe in the embodiment of the utility model comprises a supporting mechanism, as Figure 1 shown, the supporting mechanism comprises an outer circular pipe 1 and an inner circular pipe 4, the diameter of the inner circular pipe 4 is less than the diameter of the outer circular pipe 1, so that the inner circular pipe 4 can be inserted into the inside of the outer circular pipe 1; asFigure 2 and Figure 3 As shown in the figure, the side wall of the outer circular tube 1 is provided with a plurality of first pin shaft holes 9, and the side wall of the inner circular tube 4 is provided with a plurality of second pin shaft holes 10, the number and position of the first pin shaft holes 9 and the second pin shaft holes 10 correspond to each other; as Figure 1 shown, the utility model embodiment still includes the pin shaft 6, the pin shaft 6 is used for inserting the first pin shaft hole 9 and the second pin shaft hole 10 to adjust the positional relationship between the outer circular tube 1 and the inner circular tube 4.

[0021] Therefore, the adjusting tube can be inserted into the outer circular tube 1 to form a support mechanism, the side wall of the outer circular tube 1 and the inner circular tube 4 is respectively provided with the first pin shaft hole 9 and the second pin shaft hole 10, the number, size and positional relationship of the first pin shaft hole 9 and the second pin shaft hole 10 correspond to each other, the pin shaft 6 is inserted between the first pin shaft hole and the second pin shaft hole 10, so that the outer circular tube 1 and the inner circular tube 4 are fixed, when the height of the support to be required changes, the pin shaft 6 is pulled out, the inner circular tube 4 can be telescopic in the outer circular tube 1, after the inner circular tube 4 is telescopic to the height of the support to be required, the pin shaft 6 is inserted again, so that the outer circular tube 1 and the inner circular tube 4 are fixed, thereby achieving the telescopic effect of the adjusting tube, so that the support work of different heights in the construction scene can be met, compared with the existing adjusting tube of different models that needs to be customized according to the construction scene, the construction efficiency is improved, and the material cost is saved.

[0022] Preferably, as Figure 2 and Figure 3 shown, the center of each first pin shaft hole 9 forms a straight line parallel to the axis of the outer circular tube 1, and the distance between each adjacent first pin shaft hole 9 is equal, and the center of each second pin shaft hole 10 forms a straight line parallel to the axis of the inner circular tube 4, and the distance between each adjacent second pin shaft hole 10 is equal.

[0023] The benefit of such design is that the change of the support height can be measured during the construction process, the center of each first pin shaft hole 9 forms a straight line parallel to the axis of the outer circular tube 1, and is equidistantly arranged on the side wall of the outer circular tube 1, the center of each second pin shaft hole 10 forms a straight line parallel to the axis of the inner circular tube 4, and is equidistantly arranged on the side wall of the inner circular tube 4, the length of the telescopic adjusting tube can be easily known according to the correspondence between the first pin shaft hole 9 and the different second pin shaft hole 10, thereby improving the construction efficiency.

[0024] Preferably, as Figure 1 shown, the side wall of the outer circular tube 1 is provided with at least one leveling bubble instrument 5, and the leveling bubble instrument 5 is parallel to the bottom surface of the outer circular tube 1.

[0025] The benefit of the design is that the ground of the construction scene may not be flat during the construction process, which affects the support work of the adjusting pipe. Because the judgment of whether the adjusting pipe is placed well is made by manual direct observation, the error of the judgment mode is large, and the construction efficiency is low. Therefore, at least one leveling bubble instrument 5 is arranged on the side wall of the outer circular pipe 1. Whether the bubble in the leveling bubble instrument 5 is centered can be observed to judge and adjust the perpendicularity of the adjusting pipe.

[0026] Preferably, as shown in the figure, the bottom mark of the outer circular pipe 1 is provided with a center line 8. Figure 1

[0027] The benefit of the design is that the placement of the adjusting pipe should be at a specific position between the beams during construction. Therefore, the beams are first measured, and a line indicating the position where the adjusting pipe should be placed is drawn on the ground. Therefore, the center line 8 is marked on the bottom of the outer circular pipe 1, which facilitates the alignment of the center line 8 with the line drawn on the ground when the adjusting pipe is placed, thereby improving the construction efficiency.

[0028] Preferably, as shown in the figure, the top of the inner circular pipe 4 is fixed with a falling prevention steel plate 2, and the diameter of the falling prevention steel plate 2 is greater than the diameter of the outer circular pipe 1. Figure 1

[0029] The benefit of the design is that when the pin shaft is not inserted into the first pin shaft hole 9 and the second pin shaft hole 10, the inner circular pipe 4 can be displaced inside the outer circular pipe 1. In order to avoid operation errors during construction, the inner circular pipe 4 falls completely into the inner circular pipe 1 due to its own weight, thereby making it difficult to take out the inner circular pipe 4. Therefore, a falling prevention steel plate 2 is fixed at the top end of the inner circular pipe 4 to prevent the inner circular pipe 4 from falling completely into the inner circular pipe 1.

[0030] Preferably, the inner circular pipe 4 and the falling prevention steel plate 2 are connected by welding, and the welding method can be brazing.

[0031] The benefit of the design is that the overall structure of the adjusting pipe is mainly made of steel, which has a heavy weight. In order to prevent the falling prevention steel plate 2 from falling off the inner circular pipe 4, the inner circular pipe 4 and the falling prevention steel plate 2 are welded. When the inner circular pipe 4 and the falling prevention steel plate 2 need to be separated, only the welding part needs to be cut.

[0032] Preferably, the top of the falling prevention steel plate 2 is provided with a rubber pad 3.

[0033] ​​The benefit of the design is that when the support height of the adjusting pipe needs to be adjusted, the telescopic length of the inner circular pipe 4 is adjusted, but the spacing between the pin shaft holes is set in advance, and the support height of non-spacing multiples cannot be met, so the rubber pad 3 is arranged on the top of the anti-falling steel plate 2, the rubber pad 3 is elastic, the distance difference between the upper inner circular pipe 4 and the place to be supported can be compensated, and the adjusting pipe can be applied to a wider support scene.

[0034] Preferably, as shown in the figure, the end of the pin shaft 6 inserted into the inside of the support mechanism is provided with an anti-loosening clamp 7. Figure 1

[0035] The benefit of the design is that when the pin shaft 6 is inserted into the first pin shaft hole 9 and the second pin shaft hole 10, there is a gap between the pin shaft 6 and the first pin shaft hole 9 and the second pin shaft hole 10, so as to avoid loosening or falling of the pin shaft 6 in the construction process, and the anti-loosening clamp 7 is arranged at one end of the pin shaft, so as to avoid the adverse effect of loosening or falling of the pin shaft 6 on the construction.

[0036] The utility model is not only limited to the above-mentioned best implementation, and anyone can draw other various forms of products under the inspiration of the utility model, but no matter make any change in its shape or structure, if the technical scheme is same or similar to the utility model, it is in the protection scope.​
