Description
Technical field
The utility model provides a kind of fresh air ventilator air-valve aluminium section bar, belongs to air-valve valve disc field.
Background technique
Present air-valve valve disc on the market, major part is processed into by Plate Welding, due to the structural characteristics of weld seam, its good sealing cannot be ensured, and the welding of whole process need, processed complex, and weld limited strength, the problem that its intensity is low cannot be overcome.
Model utility content
The utility model object is to provide a kind of fresh air ventilator air-valve aluminium section bar, good airproof performance, and processing is simple, and intensity is high.
Fresh air ventilator air-valve aluminium section bar described in the utility model, comprise aluminium section bar, aluminium section bar is provided with fixed groove, and fixed groove two ends width reduces gradually, is provided with square tube in fixed groove, and square tube is steel pipe, and aluminium section bar one end is provided with mounting groove, is provided with Stamping Steel Ribbon in mounting groove.
Described fresh air ventilator air-valve aluminium section bar, this is designed to aluminum alloy and once draws shaping, arbitrarily cuts use during use according to concrete size, the utility model is processed very simple; In aluminium section bar, install supporting square tube and Stamping Steel Ribbon assembling, rely on steel pipe to carry out strength support, intensity comparatively general steel plate goods improves greatly; Sealing relies on Stamping Steel Ribbon and sealing surface fluid-tight engagement, and air leak rate of air curtain reduces greatly.
Described fresh air ventilator air-valve aluminium section bar, be provided with pawl in mounting groove, Stamping Steel Ribbon is provided with fixed claw, and after Stamping Steel Ribbon enters mounting groove, fixed claw can stretch in the gap of pawl.When Stamping Steel Ribbon does not insert mounting groove, fixed claw is the state perpendicular to Stamping Steel Ribbon, when inserting mounting groove, fixed claw is squeezed and is close to Stamping Steel Ribbon, when it arrives pawl, fixed claw flicks and stretches into the gap of pawl under the decision of himself quality of rubber materials, withstands pawl firmly, avoid Stamping Steel Ribbon to eject, ensure that sealing of the present utility model.
The utility model compared with prior art beneficial effect is:
Described fresh air ventilator air-valve aluminium section bar, this is designed to aluminum alloy and once draws shaping, arbitrarily cuts use during use according to concrete size, the utility model is processed very simple; In aluminium section bar, install supporting square tube and Stamping Steel Ribbon assembling, rely on steel pipe to carry out strength support, intensity comparatively general steel plate goods improves greatly; Sealing relies on Stamping Steel Ribbon and sealing surface fluid-tight engagement, and air leak rate of air curtain reduces greatly.
Described pawl and fixed claw, when Stamping Steel Ribbon does not insert mounting groove, fixed claw is the state perpendicular to Stamping Steel Ribbon, when inserting mounting groove, fixed claw is squeezed and is close to Stamping Steel Ribbon, when it arrives pawl, fixed claw flicks and stretches into the gap of pawl under the decision of himself quality of rubber materials, withstand pawl firmly, avoid Stamping Steel Ribbon to eject, ensure that sealing of the present utility model.
