Abstract
The invention discloses gradual change chair pipe outside a kind of aero seat, including：Chair tube body, the chair tube body is that middle part has centre bore, the chair tube body both ends outer wall has the armrest mounting seat of the ring-type of outwardly convex, there is the composite mounting base of the ring-type of some outwardly convexs in the middle part of the chair tube body, arm-rest frame and chair leg are installed simultaneously at the composite mounting base, due to above-mentioned setting, on the premise of if chair pipe bulk strength is not subtracted, local intensity is improved, and the weight of chair pipe will not be increased, and it is easily fabricated with processing.
Description
Technical field
The present invention relates to aero seat field, more particularly to gradual change chair pipe outside a kind of aero seat.
Background technology
Aero seat pipe is the primary load bearing pipe of aero seat, is provided with main load-bearing part chair leg and arm-rest frame thereon, is flown at present
Support chair chair in common use pipe is single elongated interior gradient tube, sets internal lining pipe to add the fragment position in arm-rest frame and chair leg position
Thickness value, due to the endoporus processing difficulties of long tube, cause high processing costs, dismounting is also inconvenient.
The content of the invention
It is an object of the invention to：Overcome the above-mentioned problems in the prior art, propose a kind of outer gradual change of aero seat
Chair pipe, according to chair pipe force status, chair tubular construction is arranged to outer gradual change type, easy to process and dismounting is safeguarded, and is being ensured
In the case of stress intensity, reduce weight as far as possible.
The purpose of the present invention is realized by following technical proposals：
A kind of outer gradual change chair pipe of aero seat, including：Chair tube body, the chair tube body are that middle part has centre bore, institute
Stating chair tube body both ends outer wall has the armrest mounting seat of ring-type of outwardly convex, has in the middle part of the chair tube body some outside
The composite mounting base of raised ring-type, arm-rest frame and chair leg are installed simultaneously at the composite mounting base, due to above-mentioned setting, not
If on the premise of subtracting chair pipe bulk strength, improving local intensity, and the weight of chair pipe will not be increased, and it is easily fabricated with
Processing.
A kind of outer gradual change chair pipe of aero seat of the present invention, the outside dimension phase of the armrest mounting seat and composite mounting base
Together, such setting will not cause stress concentration, and be easy to the standardization setting of accessory to be installed.
A kind of outer gradual change chair pipe of aero seat of the present invention, the wall thickness of the armrest mounting seat and composite mounting base is chair pipe
1.2-1.8 times of body wall thickness, it is such to set chair pipe is overall to be more uniformly stressed, machining stress is avoided the occurrence of, causes chair
The overall deformation of pipe, influences assembling and the later stage uses.
A kind of outer gradual change chair pipe of aero seat of the present invention, the armrest mounting seat and composite mounting base connect with chair tube body
Meeting place has taper transitions section, and such setting makes chair pipe have guide function when assembling is when shape part, while there is gradual change to add
Powerful, stress concentration is prevented, cause local deformation or even split absolutely.
A kind of outer gradual change chair pipe of aero seat of the present invention, the length of the taper transitions section is chair tube body external diameter
0.2-0.4 times, such setting makes the physical properties of chair pipe reach optimal, while easily fabricated.
A kind of outer gradual change chair pipe of aero seat of the present invention, armrest mounting seat and the composite mounting base surface has some
The strengthening groove axially extending along chair tube body, such setting adds local bending resistance shearing strength, and treats assembly parts
Anti-rotation set offer condition.
According to above-mentioned technical proposal, the beneficial effects of the invention are as follows：A kind of outer gradual change chair pipe of aero seat is proposed, according to chair
Pipe force status, chair tubular construction being arranged to outer gradual change type, easy to process and dismounting is safeguarded, and in the feelings for ensureing stress intensity
Under condition, reduce weight as far as possible.
Brief description of the drawings
Fig. 1 is a kind of outer gradual change chair pipe schematic diagram of aero seat of the present invention.
