Furthermore, the flat plate is provided with two flaky connecting parts at the bottom, and two holes are formed in the middle of the two connecting parts.

Furthermore, the supporting legs are inclined, and the inclined direction is the width direction of the flat plate; the upper part of the supporting leg is provided with a connecting part which is vertical and is provided with a hole in the middle, and the symmetrical positions of the two sides of the middle part of the supporting leg are provided with an upper group of connecting parts which are vertical and are provided with holes in the middle; the supporting leg is provided with two sheet-shaped connecting parts with holes in the middle at the rear part.

Furthermore, threaded holes are formed in the two sides of the upper side rail; the upper side rail is provided with a step bulge with two holes on the side surface in the middle.

Furthermore, through holes are formed in two ends of the lower side rail, and a sheet-shaped connecting part with two holes is arranged in the middle of the lower side rail.

Furthermore, the steps with holes are arranged on the two ends of the upper side baffle.

Furthermore, the two ends of the lower side bumper are provided with steps with holes, and the middle of the lower side bumper is provided with a sheet-shaped connecting part with two holes.

Furthermore, the two ends of the bevel edge gear are sheet-shaped connecting parts which are obliquely arranged and provided with holes.

Compared with the prior art, the invention has the following remarkable advantages:

1. the invention is assembled together by a plurality of flat plates and supporting legs in a detachable way, the supporting legs are connected by the lower side rail, the oblique side rail and the oblique side rail, a stable triangular structure is formed among the oblique side rail, the lower side rail and the supporting legs, and a triangle is also formed among the oblique side rail, the lower side rail and the supporting legs, thereby ensuring the bearing capacity of the platform. 2. The invention uses the parts with the same shape, and is convenient for batch processing. 3. The invention can conveniently change the length of the platform under the conditions of increasing the number of parts and not changing the size of the parts, and has better flexibility. The invention is used for the air cannon bearing platform, if the platform is corroded, only the corroded part can be replaced, and the expenditure is saved.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1-10, a detachable bearing platform is assembled by 9 detachable parts, namely a flat plate 1, an upper side rail 2, a lower side rail 3, an upper middle rail 4, an upper side rail 5, a lower side rail 6, a bevel side rail 7, a bevel side rail 8 and a supporting leg 9. Each part is used for multiple times, and batch production is facilitated. Each part is provided with a bolt connecting part, so that the assembly and disassembly are convenient.

The detachable bearing platform can be lengthened as required, and 3 flat plates are used in the implementation. Every increase 1 flat board, should increase 1 correspondingly and go up the well shelves, 2 last shelves, 2 lower side shelves, 2 supporting legs, 2 oblique side shelves, 4 oblique side shelves.

The connection part of the flat plate 1 with the upper edge rail 2 and the upper middle rail 4 is shown in fig. 3 and 4, and the two

sides

11, 12 and 21 are connected through bolts and nuts. The details of its assembly are shown in figure 5.

The connection parts of the upper side rail 2, the upper middle rail 4 and the supporting leg 9 are shown in figures 4 and 10, the hole 22 in the figures is a threaded hole, the connection parts of the upper side rail 5 and the supporting leg 9 are shown in figures 6 and 10, and the upper side rail 91, the middle rail 51 and the supporting leg 22 are connected through bolts.
