Abstract
The utility model discloses a wall thickness variable metal tapered pipe, and belongs to the technical field of building metal pipes. The wall thickness variable metal tapered pipe is used for solving the problems of high production cost, high gravity center and instability of a lamp pole, a sign post, a communication rod, a flagpole and the like. The wall thickness variable metal tapered pipe comprises a small pipe end, a pipe body and a large pipe end, wherein the external diameters of the small pipe end, the pipe body and the large pipe end are gradually increased; and the wall thicknesses of the small pipe end, the pipe body and the large pipe end are gradually increased. The wall thickness variable metal tapered pipe can be widely applied to various rod pieces bearing bending force.
Description
Technical field
The utility model relates to a kind of conical metal pipe, particularly a kind of variable-wall metal conical pipe.
Background technology
At present, the illumination lamp stand of using in places such as urban road, bridge and open decks, flagpole, highway sign bar, widely-used rod such as communication rod, conical cement pole or roll the splicing conical pipe that forms with the steel plate segmentation.Rod and cement pole exist defective not attractive in appearance and the installation inconvenience; And the present conical metal pipe of producing all is to wait wall thickness, there is waste raw material, cost of production height, product center of gravity height and uses unsettled deficiency.
Summary of the invention
The utility model overcomes deficiency of the prior art, provide a kind of save raw material, cost of production at the bottom of, the product center of gravity is low and use stable variable-wall metal conical pipe.
In order to solve the problem of above-mentioned technology; The utility model is realized through following technical scheme: the variable-wall metal conical pipe comprises pipe small end, body and Guan Daduan; Described pipe small end is to increase gradually through the external diameter that body arrives Guan Daduan, and described pipe small end process body is a progressive additive to the wall thickness of Guan Daduan.
The utility model also can be realized through following technical scheme: described body (2) length is 5～14 meters.
The utility model also can be realized through following technical scheme: described body (2) external surface tapering is 1: 80～1: 200.
The utility model can also be realized through following technical scheme: described body (2) inner surface tapering is 1: 70～1: 95.
Compared with prior art, the beneficial effect of the utility model is:
1, saves raw material.Wall thickness steel tubes such as variable-wall metal conical pipe ratio are saved steel and are reached 10～15%, and profit significantly improves under the equal price.
2, the center of gravity of product is low, good stability.The thickness of pipe wall of variable-wall metal conical pipe is successively decreased by big the end to small end gradually, and its center of gravity ratio waits more convergence bottom of wall thickness steel tube, and its stability is better when receiving external force.
Description of drawings
Fig. 1 is the generalized section of the utility model.
In the accompanying drawings: 1-pipe small end, 2-body, the big end of 3-pipe.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: the variable-wall metal conical pipe comprises pipe small end 1, body 2 and Guan Daduan 3; Described pipe small end 1 is increase gradually through the external diameter of body 2 to Guan Daduan 3, and described pipe small end 1 is a progressive additive through the wall thickness of body 2 to Guan Daduan 3.By the minimum pipe small end 1 of external diameter, arrive the maximum Guan Daduan 3 of external diameter through body 2, be the taper that increases progressively gradually, pipe small end 1 is increase gradually through the wall thickness of body 2 to Guan Daduan 3.Body 2 length of variable-wall metal conical pipe are 10000 millimeters, and pipe small end 1 is of a size of: straight through 89 millimeters, and 3 millimeters of wall thickness, Guan Daduan 3 is of a size of: straight through 219 millimeters, 5 millimeters of wall thickness.
Claims (5)
1. variable-wall metal conical pipe; Comprise pipe small end (1), body (2) and Guan Daduan (3); It is characterized in that: described pipe small end (1) is to increase gradually through the external diameter that body (2) arrives Guan Daduan (3), and described pipe small end (1) process body (2) is a progressive additive to the wall thickness of Guan Daduan (3).
2. variable-wall metal conical pipe as claimed in claim 1 is characterized in that: described body (2) length is 5～14 meters.
3. according to claim 1 or claim 2 variable-wall metal conical pipe, it is characterized in that: described body (2) external surface tapering is 1: 80～1: 200.
4. according to claim 1 or claim 2 variable-wall metal conical pipe, it is characterized in that: described body (2) inner surface tapering is 1: 70～1: 95.
