The extension tool of a kind of aluminum pipe
Technical field
The present invention relates to the extension tool of a kind of aluminum pipe.
Background technology
It is all the clamping to its two ends that tradition hangs the fixing of the right aluminum pipe of tool, and therefore, tradition hangs the area that tool easily occupies plating needed for aluminum pipe outer wall in the process that aluminum pipe is fixing or sprays paint, and affects the effect that aluminum pipe sprays paint or electroplates.
Summary of the invention
The present invention provides the extension tool of a kind of aluminum pipe, solves and hangs tool to the defect of the fixing inconvenience of aluminum pipe in the past.
The technical solution adopted in the present invention is to achieve the above object of the invention: the extension tool of a kind of aluminum pipe, comprise montant and it is arranged on the cross bar bottom montant, the upper end of this montant is provided with mounting part, is provided with some in the lower section of described cross bar for connecting the stationary installation of aluminum pipe;
The overall V-shaped structure of stationary installation, this stationary installation comprises straight bar connection section, bending part and elasticity activity portion, this stationary installation forms a fixed connection through straight bar connection section upper end and cross bar, is respectively arranged with for the protrusion top-joining part with aluminum pipe contact internal walls on described straight bar connection section and elasticity activity portion.
Stationary installation through this v-shaped structure can directly be plugged in required fixing aluminum pipe, and stationary installation relies on the protrusion top-joining part in bar connection section and elasticity activity portion and aluminum pipe inwall to hold fixing, aluminum pipe is installed fixing reliable, also reduces stationary installation occupying aluminum pipe outer wall and end wall area simultaneously.
Further, described elasticity activity portion comprises the first elasticity sheet and the 2nd elasticity sheet, the bottom of described first elasticity sheet is connected with bending part, the upper end of the first elasticity sheet is connected with the 2nd elasticity sheet, angle �� is formed between first elasticity sheet and straight bar connection section, angle �� is formed, angle �� < angle �� between 2nd elasticity sheet and straight bar connection section. Elasticity activity portion after possessing two kinds of different angles, guide portion when the first elasticity sheet of bottom can insert as aluminum pipe, thus convenient by aluminum pipe grafting,
Further, described angle �� is 2 �㡫7 ��, and angle �� is 8 �㡫12 ��.
Further, the protrusion top-joining part in elasticity activity portion is positioned on the 2nd elasticity sheet.
Further, described mounting part comprises the bolt web plate and crotch of offering bolt hole, and described bolt web plate is connected with montant top, and crotch is fixedly connected with bolt web plate.
The invention has the beneficial effects as follows: can by aluminum pipe is fixed on extension tool by holding of aluminum pipe inwall, it is to increase the fixed effect of right aluminum pipe, avoid stationary installation to occupy the outer wall of aluminum pipe and the area of end wall.

Embodiment
As shown in Fig. 1 Fig. 2, the extension tool of a kind of aluminum pipe, comprises montant 1 and is arranged on the cross bar 3 bottom montant 1, the upper end of this montant 1 is provided with mounting part 2, is provided with some in the lower section of cross bar 3 for connecting the stationary installation 4 of aluminum pipe. Stationary installation 4 is disposed in parallel in the lower section of cross bar 3.
As shown in Figure 3, the overall V-shaped structure of stationary installation 4, this stationary installation 4 comprises straight bar connection section 41, bending part 42 and elasticity activity portion 43, this stationary installation 4 forms a fixed connection through straight bar connection section 41 upper end and cross bar 3, is respectively arranged with for the protrusion top-joining part 44 with aluminum pipe contact internal walls on straight bar connection section 41 and elasticity activity portion 43. Protruding top-joining part 44 is the U-shaped portion that on device complications are formed in fact.
Stationary installation 4 through this v-shaped structure can directly be plugged in required fixing aluminum pipe, and stationary installation 4 relies on the protrusion top-joining part 44 in straight bar connection section 41 and elasticity activity portion 43 to hold fixing with aluminum pipe inwall, aluminum pipe is installed fixing reliable, also reduces stationary installation 4 occupying aluminum pipe outer wall and end wall area simultaneously.
Elasticity activity portion 43 comprises the first elasticity sheet 431 and the 2nd elasticity sheet 432, the bottom of the first elasticity sheet 431 is connected with bending part 42, the upper end of the first elasticity sheet 431 is connected with the 2nd elasticity sheet 432, angle �� is formed between first elasticity sheet 431 and straight bar connection section 41, angle �� is formed, angle �� < angle �� between 2nd elasticity sheet 432 and straight bar connection section 41. Angle �� is 2 �㡫7 ��, it is preferable that 6 ��, and angle �� is 8 �㡫12 ��, it is preferable that 9 ��. Elasticity activity portion 43 after possessing two kinds of different angles, guide portion when the first elasticity sheet 431 of bottom can insert as aluminum pipe, thus convenient aluminum pipe is plugged on the first elasticity sheet 431. Protrusion top-joining part 44 in elasticity activity portion 43 is positioned on the 2nd elasticity sheet 432.
Mounting part 2 comprises the bolt web plate 21 and crotch 22 of offering bolt hole, and bolt web plate 21 is connected with montant 1 top, and crotch 22 is fixedly connected with bolt web plate 21. Can realize making mounting mode more various the mounting hanging tool by crotch 22 and bolt web plate 21.
Can by aluminum pipe be fixed on extension tool by holding of aluminum pipe inwall, it is to increase the fixed effect of right aluminum pipe, avoid stationary installation 4 to occupy the outer wall of aluminum pipe and the area of end wall.
Below the preferred embodiment of the present invention is described in detail. It is to be understood that the those of ordinary skill of this area just can make many modifications and variations according to the design of the present invention without the need to creative work. Therefore, the technical scheme that all technician in the art can be obtained by logical analysis, reasoning, or a limited experiment under this invention's idea on the basis of existing technology, all should fall within the scope of protection of the present invention.
