Description

MOD

Technical field

The utility model relates to MOD, belongs to the technical field of mechanical invention.

Technical background

Air door in some suction-types or eliminating formula, usually reach the purpose of closing with manual locking device, a kind of air door of translation is disclosed in Chinese patent CN99221444.0, it comprises: the coverboard that has the air port, the left and right air door of shutoff on this air port on the coverboard above this air port, is hinged on respectively on the end of the fan-shaped left and right air door of bar by two hinges at a distance of suitable distance, two air doors are buckled into whole fan-shaped air door mutually by the intermeshing part teeth in its end; On the coverboard of right air door or appropriate position, the left air door outside, cut with scissors intrinsic lever connecting rod mechanism by fixing hinge, this mechanism is hinged to the double lever linkage by hinges and lever-type right air door or left air door, this structural change the inconvenience that in the past simply brought with manual mode, but because its structure is comparatively complicated, and automatization level is lower, thereby range of application is little.

Summary of the invention

The utility model purpose is to provide a kind of MOD, has solved problems such as complex structure, automatization level that prior art exists are not high.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:

A kind of MOD, comprise upper wind door, lower wind door and housing, it is characterized in that described housing is made of loam cake and lower cover, establish motor on the housing, loam cake and lower cover are provided with revolving fragment in the formed gap, one end of revolving fragment is hinged with the fixed axis that is fixed in the housing, and the other end of revolving fragment is provided with tooth, and described tooth matches with the gear of motor output shaft.Wherein upper wind door and lower wind door are respectively with the ventilation road junction of external equipment, loam cake is generally fixedlyed connected by screw with lower cover, middle part, the fixing back of loam cake and lower cover forms clearance portion, in the described clearance portion revolving fragment is arranged, be provided with porosely at revolving fragment one end, revolving fragment is hinged by hole and fixed axis, another end edge portion of revolving fragment has the gear teeth, the gear teeth are meshed with the gear of being located at the motor output shaft on housing top, and when motor shaft rotated, the gear driven revolving fragment on the output shaft rotated around fixed axis.Motor can backward rotation, and the positive negative output by motor makes revolving fragment back and forth rotate around fixed axis like this, just can open or close air door when revolving fragment forwards the relevant position to.

As preferably, described housing is semicircle, and described revolving fragment is fan-shaped, and the fixed axis other in the housing center of circle vertically is located between loam cake and the lower cover.Housing is semi-circular, and revolving fragment and housing are concentric, fixed axis just be located at housing in the heart, the axle vertically be located at loam cake and under cover, accept comparatively firm.

As preferably, described housing camber border seal, the string shape rim openings of housing, opening part is provided with limiting section.The housing lower ending opening can make things convenient for the pressure release in the housing, at opening part limiting section is set and prevents the motion of the revolving fragment excess of stroke, and described limiting section can be that the raised line that vertically is located at loam cake inside is set, and also can be provided in a side of the hold-down screw between loam cake and lower cover.

As preferably, described revolving fragment is that central angle is the fan-shaped of 90 degree, and described fixed axis is located at the center of circle of housing, and the gear of motor output shaft and revolving fragment are in same plane.Because housing is semicircle, the center of revolving fragment is located at the center of circle portion of housing, has fixed axis that revolving fragment and housing is hinged at the center, when revolving fragment is in a side of air door, air door is closed, and air door is opened when revolving fragment is turned to opposite side by motor.

As preferably, described revolving fragment is provided with the through hole that cooperates with upper wind door, and the diameter of through hole is more than or equal to the diameter of upper wind door.When the through hole of swivel plate alignd with last lower wind door, air door was in open mode, and when the through hole of swivel plate and last lower wind door staggered fully, air door was closed.

As preferably, described housing is semicircle, described revolving fragment is that central angle is the fan-shaped of 90 degree, described fixed axis is located on the center of circle of housing, the gear of motor output shaft and revolving fragment are in same plane, revolving fragment is provided with the through hole that cooperates with described upper wind door, and the diameter of described through hole is more than or equal to the diameter of upper wind door.

Therefore, the utlity model has characteristics such as simple in structure, automaticity height.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of the present utility model;

Accompanying drawing 2 is side views of Fig. 1.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: a kind of MOD as illustrated in fig. 1 and 2, housing includes loam cake and lower cover, lower cover and loam cake are fixed by screw, gapped between loam cake and lower cover, on cover and be provided with upper wind door 3, under cover to be provided with and be provided with revolving fragment 4 and fixed axis 7 in lower wind door 9 gaps, the middle part of revolving fragment 4 is provided with the through hole that cooperates with last lower wind door, described fixed axis 7 fixed vertical are located between loam cake and lower cover, revolving fragment 4 is socketed on the fixed axis 7 by through hole, revolving fragment 4 can rotate freely in loam cake and lower cover institute area surrounded around fixed axis 7, be provided with motor 8 in the housing upper end, the gear 1 of the output shaft of motor 8 is located in the housing, gear 1 meshes with the tooth of the end of revolving fragment, the rotation of motor shaft drives the rotation of revolving fragment, whole state when through hole on the revolving fragment and upper wind door 3 and lower wind door 9 are to it like this for opening, reverse-rotatable motor, the gear 1 of the output shaft of motor can drive revolving fragment 4 backward rotation, when the through hole of revolving fragment 4 with when stagger fully in the air port up and down, the motor air door is in closed condition, motor links to each other with control circuit board 6 by control line 5, so just can control the open and close of motor air door as required.Described revolving fragment is that central angle is the fan-shaped of 90 degree, and described fixed axis is located at the center of circle of housing, and the gear of motor output shaft and revolving fragment are in same plane.The string shape lower ending opening of housing, opening part is provided with stop screw 10, and stop screw both can limit the maximum rotated position of revolving fragment, described loam cake and lower cover can be locked together securely again, the arc end outer rim of housing is for what seal, and linear lower ending opening can make things convenient for the pressure release in the housing.
