Furthermore, a rotating handle is fixed on the outer side wall of the supporting fine adjustment nut.

Furthermore, a baffle is fixed on the outer side wall of the upper end of the inner pipe.

The utility model has the advantages that: the extension length of the inner pipe can be quickly adjusted; and the larger the pressure of the top end to the inner pipe is, the larger the locking force of the device is, the firmer the inner pipe is fixed, and the safety factor is improved.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, and as shown in fig. 1 to 6, a non-porous adjustable single support comprises a bottom plate 1, a mounting hole 2, an outer tube 3 and an inner tube 4, wherein the mounting hole 2 is processed on the bottom plate 1, the outer tube 3 is fixed at the top end of the bottom plate 1, and the inner tube 4 is arranged in the outer tube 3; the outer side wall of the upper end of the outer tube 3 is provided with an external thread, the support fine adjustment nut 7 is connected with the outer side wall of the upper end of the outer tube 3 through an internal thread, the outer side wall of the support fine adjustment nut 7 is fixedly provided with a rotating handle 8, and the rotating handle 8 is favorable for rotating the support fine adjustment nut 7, so that the support fine adjustment nut 7 finely adjusts the extending length of the inner tube 4; a conical sleeve 9 is arranged at the top end of the supporting fine adjustment nut 7, two adjusting long holes 10 are symmetrically formed in the conical sleeve 9, two conical half-ring locking plates 11 are symmetrically arranged in the conical sleeve 9, anti-skidding teeth 13 are machined at the ends, close to each other, of the two conical half-ring locking plates 11, the anti-skidding teeth 13 are in contact with the outer side wall of the inner tube 4, and the anti-skidding teeth 13 are beneficial to clamping the inner tube 4; an extension rod 12 is fixed at one end of each conical semi-ring locking piece 11, which is far away from each other, and the extension rod 12 extends out of the conical sleeve 9 through the adjusting long hole 10; a blocking sleeve 6 is fixed on the outer side wall of the lower end of the inner pipe 4, the blocking sleeve 6 is arranged in the outer pipe 3 in a sliding mode, the blocking sleeve 6 is beneficial to keeping the vertical stability of the inner pipe 4, and the conical semi-ring locking plate 11 can be prevented from falling off the inner pipe 4; the baffle 5 is fixed on the outer side wall of the upper end of the inner pipe 4, and the baffle 5 can prevent the conical sleeve 9 and the conical half-ring locking plate 11 from being separated.

In this embodiment, when it is desired to use the device, the device is in the position shown in figure 1, with the top end of the inner tube 4 being used to support a weight; under the action of the gravity of the inner tube 4, friction force is generated between the inner tube 4 and the two tapered half-ring locking plates 11, the two tapered half-ring locking plates 11 move downwards, the tapered sleeve 9 prevents the tapered half-ring locking plates 11 from moving downwards, and the inner tube 4 is fixed; the larger the pressure at the top end of the inner pipe 4 is, the firmer the inner pipe 4 is fixed, and the safety factor is improved. When the adjustment is needed, the extension rod 12 is knocked upwards by using a tool, so that the two conical half-ring locking plates 11 move upwards to not clamp the inner pipe 4 any more, the extension height of the inner pipe 4 can be adjusted, and the inner pipe 4 can be locked again after the extension rod 12 is loosened after the adjustment is finished.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
