Description

A kind of adjustable wind outlet unit

[technical field]

The utility model relates to a kind of adjustable wind outlet unit, belongs to adjustable to ventilation unit parts technical field indoor or place importing or air distribution.

[background technology]

Common adjustable wind outlet unit, it comprises the horizontal blade group on the two short sidewalls that are fixed in front baffle, be positioned at vertical vane group fixing on the two long sidewalls of horizontal blade group rear and former frame frame and the afterframe that is covered on four trailing flanks of front baffle, front baffle and afterframe are all formed through riveted joint or welding assembly by aluminium alloy extrusions, the two rotation end axles that vertical each blade of vane group passes framework link to each other with connecting rod by adaptor respectively, one of each blade rotation end axle is respectively arranged with the axial thread hole in the horizontal blade group, spin fixing with each blade of corresponding horizontal vane group after passing each circular hole of offering on the short sidewall of front baffle by trip bolt, one of the column structure that has that each blade passes the short sidewall of front baffle in the horizontal blade group rotates the end axle and is provided with governor motion, this governor motion comprises holder, adjustment disk, flat shim and fastening bolt, holder be placed in this rotate that the end axle is gone up and the corresponding mounting hole of the short sidewall of bearing pin holding former frame frame by its two end in, make the fixed seating in the lateral surface of the short sidewall of front baffle, adjustment disk offers the suitable post hole of column structure of rotating the end axle therewith, adjustment disk is arranged in this rotation end axle by this post hole and goes up and be stacked at outside the said fixing seat, be arranged with adaptive shrinkage pool and protruding grain on holder and the adjustment disk opposite face by circle distribution, refill and rotate the end axle therewith by trip bolt behind the flat shim and screw togather, holder and adjustment disk axially fasten in rotating on the end axle, but and make above-mentioned adjustment disk relative fixed seat be closely chimeric rotationally, thereby realize regulating the horizontal blade inclination angle to change the purpose of air-out angle.

Anatomize said structure, be not difficult to find that there is following weak point in it:

1, the rotation end axle of each blade need could be affixed by trip bolt with connecting rod by each adaptor in the horizontal blade group, and parts are many, cause its manufacturing cost of wind outlet unit to raise up, and rotate the end axle and all need offer internal thread and just can screw togather fixingly, and manufacturing procedure is many;

2, another rotation end axle of each blade all need be installed the governor motion that is made of family of four in the horizontal blade group, rotate the internal thread that end axle surface also need be processed into column and Gong screw togather, holder in the family of four and adjustment disk complex structure, manufacturing procedure is cumbersome, and die sinking cost height, family of four are fixed in the rotation end axle of manual blade, make that the wind outlet unit assembling is complicated, in today that cost of labor is expected to rise, unit cost is unprecedentedly soaring, thus the forfeiture product competitiveness;

3, the wind outlet unit of aluminum alloy material easy condensation when sending cold wind, thereby have the practicality deficiency.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of adjustable wind outlet unit at the above-mentioned state of the art, and that the governor motion of regulating this device horizontal blade has is simple for structure, processing request is low, assemble characteristics efficiently.

It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of adjustable wind outlet unit, comprise by two short side plates and two long side plates and surround the front baffle that forms, two short side plate installed inside have the horizontal blade group, four fixedly connected afterframes of side plate end face of front baffle, the horizontal blade group can manually swing up and down, to regulate the wind direction of vertical direction, one of each blade rotation end axle passes the corresponding axis hole setting of offering on the short side plate respectively in the horizontal blade group, another short side plate and with the corresponding afterframe of this short side plate on offer each blade in the water supply flat blade group another rotate paired half round cut that the end axle is shelved, be provided with governor motion between another rotation end axle of each blade and described another short side plate in the horizontal blade group, this governor motion comprises that being arranged at described another rotates the sector gear that the cavity that another short side plate offers was gone up and be positioned to the end axle, and cavity is equipped with the toothed flat spring that supplies the sector gear Elastic Meshing.

Above-mentioned toothed flat spring comprises that the longitudinal cross-section has two bases and connects the arch area at two ends and laterally be convexly set in the teeth at this arch area concavity place, and two bases of flat spring are placed in the bottom of described cavity; To rotate the end axle be overall structure with being arranged at the sector gear that rotates on the end spool for another of each blade in the horizontal blade group.

Its corresponding rotation end of the sector gear of each blade axle one design in the horizontal blade group, two unite two into one, and can improve the manufacturing work efficiency, reduce assembly process.

At least be provided with a bracing piece muscle between two short side plates of above-mentioned front baffle, the horizontal blade group has two groups at least, one of each blade rotates the end axle and is placed through the axis hole that bracing piece muscle respective side walls is offered in every group of horizontal blade group, another of each blade rotates between end axle and the corresponding short side plate and is provided with governor motion in every group of horizontal blade group, each short side plate and with the corresponding afterframe of this short side plate on all offer for another of each blade in every group of horizontal blade group and rotate end paired half round cut of shelving.

Because wind outlet unit length in the horizontal direction is longer, the reinforcement bar of setting up vertical direction can be strengthened the intensity of front baffle, and elsewhere, this reinforcement bar also can play the effect of support horizontal blade.

Four strip side plates of above-mentioned formation front baffle and the bracing piece muscle that is arranged on the front baffle are integral molded plastic spare, and afterframe, horizontal blade group, vertical vane group and governor motion are all moulding.Adopt integral molded plastic spare, can improve anti-condensation ability.

In the two long side plate installed inside that are positioned at horizontal blade group rear and former frame frame the moving vertical vane group of electric pendulum is arranged, to regulate the wind direction of horizontal direction.

The advantage that the utility model compared with prior art has is:

The rotation end axle of each blade rotates with the corresponding axis hole of a short side plate and connects, after lid is established afterframe, another of each blade rotates the paired half round cut that the end axle then is positioned at another short side plate and the amalgamation of afterframe institute, realized that the horizontal blade group can rotate up and down, all rotate the end axle and have all save securing member, reduce manufacturing procedure, saved the assembly work amount; This governor motion only can be realized swinging up and down of horizontal blade group by sector gear and toothed flat spring, its structure is simple for structure, die sinking is few, requirement on machining accuracy is low and operation is few, the assembling efficient quick, therefore has the market competitiveness, and because the elastic construction of flat spring, make the governor motion stable and smooth operation, so the horizontal blade group has the little advantage of the noise of rotation.

Above-mentioned advantage has compared with prior art embodied progressive of the present utility model.
