Description

Aluminum alloy telescopic support

Technical Field

The utility model relates to a shipping container field specifically is an aluminum alloy telescopic prop.

Background

The existing shipping container is fixedly connected with a fixed iron square tube welded on a platform box, and the applicant applies an aluminum alloy support column to replace the original fixed iron square tube welded on the platform box, as shown in figure 1, the advantages that the support column can be separated from the platform box, the logistics transportation cost is reduced, the operation is simple, the operation efficiency is improved, and the like are achieved.

However, in use, the aluminum alloy upright posts are found to be very short or very long when the size and specification of materials are changed (the size is increased or reduced), and the storage space between the platform boxes is reduced or enlarged; at the moment, the pillars with different specifications need to be continuously replaced, so that time and labor are wasted, and the cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve prior art's problem, provide an aluminum alloy telescopic prop, the flexible function through interior outer tube changes the length of pillar to change the storage space between the platform case, accomplished the advantage that the transportation is convenient, product convenient operation, save the cost.

The utility model comprises an inner pipe and an outer pipe which are nested and matched, wherein an aluminum alloy angle piece is welded at the top of the outer pipe, a forging lock head with a thread locking device is welded at the bottom of the inner pipe, and the inner pipe is inserted into the outer pipe and slides along the inner wall of the outer pipe; the outer pipe and the inner pipe are provided with a plurality of pairs of through holes, and the solid pins are inserted into the through holes on the inner pipe and the outer pipe to fix the inner pipe and the outer pipe.

In a further improvement, the solid pin is fixed by a spring pin.

The improved structure is characterized in that the outer pipe is provided with a group of through holes located on the same horizontal plane, the inner pipe is provided with three groups of through holes located at the upper, middle and lower positions, and when the through holes of the outer pipe and the through holes of the inner pipe are fixed, the total length of the corresponding inner pipe and the corresponding outer pipe is respectively 4 feet, 5 feet and 6 feet.

The utility model has the advantages that:

1) the sizes of common specifications are combined on one product through the extension and contraction of the inner pipe and the outer pipe, so that more product types are avoided, and the cost is saved;

2) the disassembly is convenient, and the operation is simple and uncomplicated;

3) the platform box has stronger material storage space flexibility and is convenient to transport.

Drawings

FIG. 1 is a schematic view of a conventional aluminum alloy pillar.

Fig. 2 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The structure of the utility model is as shown in figure 1, comprising an inner tube 2 and an outer tube 3 which are nested and matched, an aluminum alloy corner fitting 4 is welded on the top of the outer tube 3, a forging tapered end 1 with a thread locking device is welded on the bottom of the inner tube 2, and the inner tube is inserted into the outer tube and slides along the inner wall of the outer tube; the outer pipe and the inner pipe are provided with a plurality of pairs of through holes, and the solid pins 5 are inserted into the through holes on the inner pipe and the outer pipe to fix the inner pipe and the outer pipe.

In a further improvement, the solid pin is fixed by a spring pin.

When the height of 4 feet is needed, the outer pipe is stretched to the lowest opposite-penetrating hole position of the inner pipe, then the solid pin is inserted into the opposite-penetrating hole and is fixed by the spring pin, and the using length of the telescopic support is 4 feet, 5 feet and 6 feet, and the like.

The utility model discloses the concrete application way is many, and the above-mentioned only is the preferred embodiment of the utility model, should point out, to ordinary skilled person in this technical field, under the prerequisite that does not deviate from the utility model discloses the principle, can also make a plurality of improvements, and these improvements also should be regarded as the utility model discloses a protection scope.
