Description

Rack

The utility model relates to a kind of rack, particularly a kind of dismountable rack.

In the prior art, a kind of dismountable rack is arranged, this rack, it comprises the grid-like glove table top that a plurality of gloves are used and is used for supporting four standpipes of these a plurality of glove table tops;

On four jiaos of each described glove table top, be equipped with hollow bushing, in this hollow bushing, also be provided with sheath;

The top mouth of pipe of described four standpipes is blind end, each standpipe is linked to each other by two pipe joints at least and forms, equidistantly on the outer rim of each pipe joint be provided with a plurality of annular grooves, between every adjacent 2-section pipe, be equipped with the connector that this 2-section pipe is fused, described connector is to be made of the externally threaded connection double-screw bolt of double headed roller, therefore in the mouth of pipe of each pipe joint, all need be provided with and be connected the internal thread that double-screw bolt matches with this, the technology of machining internal thread is comparatively complicated, and its connection fastness is also good inadequately.

The purpose of this utility model is to provide a kind of standpipe to connect that fastness is good, pipe joint is processed simple rack.

The purpose of this utility model is achieved in that

This rack, it comprises the grid-like glove table top that a plurality of gloves are used and is used for supporting four standpipes of these a plurality of glove table tops;

On four jiaos of each described glove table top, be equipped with hollow bushing, in this hollow bushing, also be provided with sheath;

The top mouth of pipe of described four standpipes is blind end, each standpipe is linked to each other by two pipe joints at least and forms, equidistantly on the outer rim of each pipe joint be provided with a plurality of annular grooves, between every adjacent 2-section pipe, be equipped with the connector that this 2-section pipe is fused, it is characterized in that described connector is to be made of the elasticity steel pipe; Total length at this this steel pipe tube wall of steel pipe upper edge has a slit, on the outer rim of the central authorities of this steel pipe, be provided with a location dome, on the up and down two-part outer rim of this location dome, be respectively equipped with and be used for the steel pipe annular groove that matches with annular groove on the described pipe joint, the bore of the two ends mouth of pipe of this steel pipe is all less than the caliber of steel pipe, also is respectively equipped with to be used to increase the flexible a plurality of recesses of this mouth of pipe on this two ends mouth of pipe;

Chamfering and interior chamfering outside on the outer rim of the mouth of pipe of adjacent 2-section pipe and inner edge, being respectively equipped with, the right-angle side of described outer chamfering is 1/2 of a described annular groove width, adjacent two described in chamferings be harmonious and constitute a synthetic annular groove in described dome can being wrapped in;

Described elasticity steel pipe is that its two ends, center are inserted in respectively in the mouth of pipe of adjacent 2-section pipe with the dome, and is tight fit with this 2-section pipe.

The utility model is owing to make the whippy connector that has described slit, recess with described connector, described elasticity steel pipe is when linking to each other with 2-section pipe, not only insert easily, and its connection fastness is good, and need not to establish again internal thread on each pipe joint, therefore simplified the processing technology of pipe joint; Again because chamfering and interior chamfering outside being respectively equipped with on the outer rim of the mouth of pipe of adjacent 2-section pipe and inner edge, so this elasticity steel pipe do not see the vestige of connection when being connected with 2-section pipe, thereby guaranteed the integrated beauty of the outward appearance of standpipe.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of rack described in the utility model.

Fig. 2 is the structural representation of described elasticity steel pipe.

Fig. 3 is the state reference map of described elasticity steel pipe when being connected with 2-section pipe.

Fig. 4 is the enlarged drawing of A part among Fig. 3.

Describe structure in detail below in conjunction with Fig. 1～Fig. 4 according to the concrete rack that the utility model proposes.

This rack, it comprises grid-like glove table top 1 that a plurality of gloves are used and four standpipes 2 that are used for supporting these a plurality of glove table tops;

On four jiaos of each described glove table top 1, be equipped with hollow bushing 4, in this hollow bushing, also be provided with the sheath (not shown);

The top mouth of pipe of described four standpipes 2 is blind end, each standpipe is linked to each other by two pipe joints 3 at least and forms, equidistantly on the outer rim of each pipe joint 3 be provided with a plurality of annular groove 3-1, be equipped with the connector that this 2-section pipe is fused between every adjacent 2-section pipe 3, described connector is to be made of elasticity steel pipe 5; Total length at this this steel pipe tube wall of steel pipe 5 upper edges has a slit 5-1, on the outer rim of the central authorities of this steel pipe 5, be provided with a location dome 5-2, on the up and down two-part outer rim of this location dome 5-2, be respectively equipped with and be used for the steel pipe annular groove 5-3 that matches with annular groove on the described pipe joint, the bore of the two ends mouth of pipe of this steel pipe 5 is all less than the caliber of steel pipe, also is respectively equipped with to be used to increase the flexible a plurality of recess 5-4 of this mouth of pipe on this two ends mouth of pipe;

Chamfering 3-2 and interior chamfering 3-3 outside on the outer rim of the mouth of pipe of adjacent 2-section pipe 3 and inner edge, being respectively equipped with, the right-angle side of described outer chamfering 3-2 is 1/2 of a described annular groove 3-1 width, adjacent two described in chamfering 3-3 be harmonious and constitute a synthetic annular groove (not shown) in described dome 5-2 can being wrapped in;

Described elasticity steel pipe 5 is that its two ends, center are inserted in respectively in the mouth of pipe of adjacent 2-section pipe 3 with dome 5-2, and is tight fit with this 2-section pipe 3.

The utility model is specially adapted to do in the market goods carrier.
