Abstract
The invention discloses a rigidity-flexibility-combined smoke-discharging and cornering device of a range hood. The smoke-discharging and cornering device comprises a vertical pipe, a cornering pipe, a transverse pipe and a bracket which are connected by using a welding process, wherein the vertical pipe comprises a metal pipe A and a corrugated pipe A which are welded together; the cornering pipe is formed by a bent metal pipe and has the effect of connecting the vertical pipe with the transverse pipe; the transverse pipe comprises a metal pipe and a corrugated pipe which are welded together; the bracket is a metal bracket and has the effect of supporting the transverse pipe; one end of the metal pipe A in the vertical pipe is welded with the corrugated pipe A; a process notch is formed in the other end of the metal pipe A; the metal pipe A in the vertical pipe is connected with a smoke discharging pipe of the range hood. The smoke-discharging and cornering device of the range hood is formed by connecting a rigid part with a flexible part; the rigidity and the flexibility are ensured while the effective buffering effect on the vibration shock can be achieved; the smoke-discharging and cornering device of the range hood can simultaneously ensure the rigidity and the flexibility and buffer the vibration shock.
Description
Technical field
The present invention relates to oil machine technical field, particularly relate to oil machine smoke-exhaust pipeline, specifically a kind of oil machine smoke evacuation switching device of rigid flexible system.
Background technology
Current state, inside and outside oil machine smoke evacuation switching device generally adopt full rigidity, or the smoke evacuation switching device of Grazing condition.The smoke evacuation switching device of full rigidity is firm, intensity performance is excellent, but comparatively responsive to vibration, easily causes the fatigue rupture of switching device of discharging fume; The smoke evacuation switching device of Grazing condition can effectively impact by buffering vibration, but self firm, intensity show poor.
Therefore, industry needs a kind of oil machine smoke evacuation switching device of rigid flexible system.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of oil machine smoke evacuation switching device of rigid flexible system, described smoke evacuation switching device is formed by connecting by rigid element and flexible portion, while guarantee rigidity, intensity, effective buffering effect can be played to vibratory impulse, effectively can solve oil machine smoke evacuation switching device and ensure rigidity, intensity simultaneously, and the problem that buffering vibration impacts.
For solving the problem, the invention provides a kind of oil machine smoke evacuation switching device of rigid flexible system, comprising vertical tube, bending pipe, transverse tube, bracket; Described vertical tube, bending pipe, transverse tube adopt welding procedure to connect; Vertical tube comprises metal tube A and bellows A, and wherein metal tube A and bellows A is welded; Bending pipe is formed by metal tube bending, plays the effect being connected vertical tube and transverse tube; Transverse tube comprises metal tube and bellows, and wherein metal tube and bellows-welding form; Bracket is metal bracket, plays the effect supporting transverse tube.
Further, in described vertical tube, metal tube A welds with bellows A one end, and the other end arranges technical gaps, for being connected with oil machine smoke exhaust pipe.
Compared with prior art, the present invention has the following advantages:
1, because the straightway of oil machine of the present invention smoke evacuation switching device comprises the metal tube of rigidity, so oil machine of the present invention smoke evacuation switching device can ensure enough rigidity, intensity;
2, because the straightway of oil machine smoke evacuation switching device of the present invention comprises flexible bellows, so oil machine of the present invention smoke evacuation switching device can effectively impact by buffering vibration;
