Abstract
The utility model relates to an unequal wall rectangular tube for connection of bases of seats of passenger cars. The cross section of a tube body (1) of the unequal-wall rectangular tube is in an unequal-wall rectangular structure, the unequal-wall rectangular structure consists of thick straight-sided sections (1-1) and thin straight-sided sections (1-2), the top and the bottom of the tube body (1) are thick straight-sided sections (1-1), the left side and the right side of the tube body (1) are thin straight-sided sections (1-2), the thick straight-sided sections (1-1) and the thin straight-sided sections (1-2) are in circular arc transition connection, the surface of the tube body (1) is coated with an anti-rusting paint layer (2), and the unequal-wall rectangular tube is made of Q345B. The unequal-wall rectangular tube for connection of bases of seats of passenger cars is high in strength, light in weight, strong in bending resistance and torsion resistance and fine in shockproof and anti-proof effect.
Description
(1) technical field
The utility model relates to a kind of special-shaped seamless steel pipe, especially relates to a kind of bus seat chassis and connects with not waiting the wall rectangular tube, belongs to the metallic material technical field.
(2) background technique
At present, seamless steel pipe is widely used in manufacturing structure spare and mechanical parts, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle frame and the construction etc.Make ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, economical with materials and machining period as rolling bearing lasso, jack cover etc., are extensively made with seamless steel pipe at present.In these seamless steel pipes, circular pipe can be carried more fluid.In addition, ring cross-section is when bearing inside or outer radial pressure, and is stressed more even, and therefore most seamless steel pipes are pipes.
Yet pipe also has certain narrow limitation:
The shape restriction of pipe makes it can't be used for some particular surroundingss;
Because the moment of inertia of pipe and section modulus are less, its bending resistance and anti-twisting property are relatively poor, and intensity is low;
The weight of pipe itself is bigger, and is bigger to the pressure of its supporting part;
It is more to make the steel that pipe consumes, and makes that its cost is higher.
Above a variety of causes has limited the Applicable scope of pipe, does not therefore adopt pipe to be used as structural member or machine part under some particular surroundingss.For example intensity, bending resistance and the antitorque ability of self need be considered in the bus seat chassis, and wants certain shake-proof ability and antirust ability, and the front and back on bus seat chassis are stressed bigger simultaneously, so just can not use conventional pipe to make.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of bus seat chassis to connect with not waiting wall rectangular tube, and this bus seat chassis connects with the intensity height that does not wait the wall rectangular tube, and is in light weight, bending resistance, anti-twisting property are stronger, and shockproof and rust-proof effect is better.
The purpose of this utility model is achieved in that
A kind of bus seat chassis connects with not waiting wall rectangular tube, this does not wait the section of the body of wall rectangular tube to be and does not wait the wall rectangular configuration, this does not wait the wall rectangular configuration to include thick straight section and thin straight section, the top of described body and bottom are thick straight section, the left side of described body and the right are thin straight section, for arc transition is connected, the surface of described body is covered with rust preventive coating between described thick straight section and the thin straight section, and described not wait the material of wall rectangular tube be Q345B.
The beneficial effect that the utlity model has is:
This bus seat chassis connects with not waiting front and back tube wall of wall rectangular tube thicker, makes that the intensity of front-end and back-end on bus seat chassis is higher, Chair underframe in light weight, and bending resistance, anti-twisting property are stronger, can play shockproof and antirust effect well.
(4) description of drawings
Fig. 1 is that the utility model bus seat chassis connects with the cross-sectional configuration schematic representation that does not wait the wall rectangular tube.
Wherein: body 1, thick straight section 1-1, thin straight section 1-2, rust preventive coating 2.
(5) embodiment
As Fig. 1, the utility model relates to a kind of bus seat chassis and connects with not waiting wall rectangular tube, this does not wait the section of the body 1 of wall rectangular tube to be and does not wait the wall rectangular configuration, this does not wait the wall rectangular configuration to include thick straight section 1-1 and thin straight section 1-2, the top of described body 1 and bottom are thick straight section 1-1, the left side of described body 1 and the right are thin straight section 1-2, be connected for arc transition between described thick straight section 1-1 and the thin straight section 1-2, the surface of described body 1 is covered with rust preventive coating 2, and described not wait the material of wall rectangular tube be Q345B.
Claims (1)
1. a bus seat chassis connects with not waiting wall rectangular tube, it is characterized in that: this does not wait the section of the body (1) of wall rectangular tube to be and does not wait the wall rectangular configuration, this does not wait the wall rectangular configuration to include thick straight section (1-1) and thin straight section (1-2), the top of described body (1) and bottom are thick straight section (1-1), the left side of described body (1) and the right are thin straight section (1-2), be connected for arc transition between described thick straight section (1-1) and the thin straight section (1-2), the surface of described body (1) is covered with rust preventive coating (2), and described not wait the material of wall rectangular tube be Q345B.
