Summary of the invention

Main purpose of the present utility model is to provide a kind of frame plate that turns to use at the above-mentioned defective of known technology existence, the appropriate location that mainly is the beam tube inwall at four ends of this frame plate angle has a diameter reducing part, make beam tube two ends to the joining portion that respectively forms a hollow pushing and drawing shape wide outside and narrow inside between diameter reducing part, matching with the up-narrow and down-wide cone shape bushing pipe that is incorporated into the hack lever outside in this joining portion, makes the frame plate of the utility model pipe piece rack can turn to use.

For this reason, the utility model provides a kind of beam tube of improved pipe piece rack, and described pipe piece rack is assembled by number hack lever, number bushing pipe and number frame plate, and wherein: this is counted and is interval with the ring of numbers groove on the hack lever; This count bushing pipe be arc plate by two tool taperings to be buckled into the upper end bore mutually be narrow coniform body than the lower end bore, the appropriate location of two arc plate inwalls respectively is provided with a raised line and matches with annular groove on the hack lever, makes bushing pipe be bonded to appropriate location outside the hack lever; These four end angles of counting frame plate are connected with the hollow beam tube that one two end is open shape; The appropriate location of described this beam tube inwall is provided with a diameter reducing part, makes beam tube two open ends can be selected one to the joining portion that respectively forms a hollow pushing and drawing shape wide outside and narrow inside between diameter reducing part and is placed on the bushing pipe.

The beam tube of aforesaid a kind of improved pipe piece rack, the wherein outstanding respectively flange that is provided with of the root edge outer wall of this two arc plate.

Advantage of the present utility model and characteristics are: the appropriate location by above-mentioned beam tube inwall is provided with a diameter reducing part, make beam tube two open ends to the joining portion that respectively forms a hollow pushing and drawing shape wide outside and narrow inside between diameter reducing part, two joining portion can be selected one and are placed on bushing pipe and terminate in the flange top of bushing pipe, thereby make the frame plate of the utility model pipe piece rack can turn to use, satisfy different user demands.

Embodiment

In order to allow aforementioned and other purpose, feature and advantage of the present utility model understand by more obvious quilt, preferred embodiment of the present utility model cited below particularly, and cooperate appended graphicly, elaborate.Please consult earlier shown in Figure 4, pipe piece rack of the present utility model be by the number hack levers 1, the number bushing pipe 2 and the number frame plate 3 assembled, see also again shown in Fig. 1,2, this is counted and is interval with ring of numbers groove 11 on the hack lever 1; This counts bushing pipe 2, and to be buckled into the upper end bore mutually by the

arc plate

21,22 of two tool taperings be narrow coniform body than the lower end bore, the appropriate location of two arc plates, 21,22 inwalls respectively is provided with a raised line 211,221 and matches with annular groove 11 on the hack lever 1, two arc plates, 21,22 formation, one bushing pipe 2 is fixed is combined in the appropriate location in hack lever 1 outside, the outstanding respectively flange 212,222 that is provided with of the root edge outer wall of two

arc plates

21,22; This is counted four of frame plate 3 end angles and respectively is connected with the beam tube 31 that a hollow and two ends are open shape, the appropriate location of beam tube 31 inwalls has a diameter reducing part 310,311,312, two joining portion 311,312, joining portion that make beam tube 31 2 open ends to 310 of diameter reducing parts respectively form a hollow pushing and drawing shape wide outside and narrow inside can be selected one and are placed on bushing pipe 2 and terminate in flange 212,222 tops of bushing pipe 2; Two 31 of adjacent beam tubes are connected with a guardrail 32, the bottom of guardrail 32 be connected with one by the continuing surface 33 that constitutes of number bars for putting article.

See also shown in Figure 2, be not need guardrail 32 to ask for bigger smooth area for the embodiment who puts article, the joining portion 311 of beam tube 31 is placed on bushing pipe 2 and terminates in flange 212,222 tops of bushing pipe 2, so, guardrail 32 promptly is positioned at continuing surface 33 belows, therefore, article can be given prominence to continuing surface 33 ora terminalis; See also shown in Figure 3 again; when needs guardrail 32 when preventing that article from dropping; frame plate 3 is turned upside down (embodiment who does not need guardrail with Fig. 2 compares); and the joining portion 312 of beam tube 31 is placed on bushing pipe 2 and terminates in flange 212,222 tops of bushing pipe 2; so; guardrail 32 promptly is positioned at continuing surface 33 tops, and therefore, article can be protected by guardrail 32 backstops.

By above-mentioned structure, be provided with a diameter reducing part 310 when understanding the appropriate location of the utility model by beam tube 31 inwalls, make beam tube 31 2 open ends to 310 of diameter reducing parts respectively form the joining portion 311,312 of a hollow pushing and drawing shape wide outside and narrow inside, two joining portion 311,312 can be selected one and are placed on bushing pipe 2 and terminate in flange 212,222 tops of bushing pipe 2, make the frame plate of the utility model pipe piece rack can turn to use, has novelty, its effect of promoting is as above-mentioned, also have progressive, and have value on the industry.
