Abstract
The utility model provides a differential link air shutter which belongs to the technical field of fan equipment. The air shutter solves the problems that the existing rectangular air shutter has larger resistance, is uneasy in operation and the like when being opened. The differential link air shutter is characterized in that a plurality of blades are axially arranged in a barrel-shaped housing at intervals and fixed on rotating shafts perpendicular to the axis of the housing; the rotating shafts are articulated with the wall of the housing; a rocker arm is fixed at one end of each rotating shaft; all the rocker arms are arranged in the same plane in parallel and divided into two groups of rocker arms from the middle to the two sides; the two groups of rocker arms are positioned on two sides of a connection line of all the rotating shafts; and the outer ends of each group of rocker arms are articulated with a transmission link of the group. The differential link air shutter adopts differential connection and can achieve fine adjustment of air quantity, and the opening torque of the air shutter is greatly decreased.
Description
Technical field
The utility model belongs to the Fan Equipment technical field, refers in particular to a kind of differential linkage type register.
Background technique
At present; Existing rectangle register is the plain connecting rod formula; Be to connect by a connecting rod,, make connecting rod drive each blade rotating open-close air door through the pivoted arm of in the middle of rotating or end by a plurality of blades; This structure is because through a connecting rod transmission, and it is bigger and not easy to operate therefore to exist when opening resistance.
Summary of the invention
The purpose of the utility model provides resistance, the little differential linkage type register of resistance square.
The purpose of the utility model is achieved in that a kind of differential linkage type register; Axially spaced-apart is equipped with some blades in the housing of tubular; Vanes fixed is in the rotating shaft perpendicular to the housing axis, and rotating shaft is hinged on the shell body wall, and an end of each rotating shaft is fixed with rocking arm; All rocking arms are set in parallel in the same plane; It is characterized in that: all rocking arms are divided into two groups of rocking arms by the middle part to both sides, and two groups of sub rocker arms are listed in the both sides of all rotating shaft lines, and the outer end of every group of rocking arm is hinged on respectively on the kinematic link of this group; Wherein: one group of the most inboard rocking arm of rocking arm extends to form second rocking arm to another group rocking arm side; The most inboard rocking arm of another group rocking arm is a fan-shaped rocking arm, and an end of inboard, the outside hinged with this group kinematic link, the outer end of fan-shaped rocking arm and differential connecting rod is hinged, and the outer end of the other end of differential connecting rod and described hinged second rocking arm is hinged.
The utility model connects differential connecting rod through fan-shaped rocking arm, and the outer end of the differential connecting rod and second rocking arm is hinged, and the speed governing that realized being in course of adjustment is stable, reduces the moment of rotation of register, can realize the fine setting of air quantity.
In above-mentioned a kind of differential linkage type register, the rocking arm that described one group of rocking arm is the most inboard and this rocking arm are integral structure to extended second rocking arm of another group rocking arm side.
In above-mentioned a kind of differential linkage type register, described rotating shaft is connected on the bearing support on the shell body wall.
In above-mentioned a kind of differential linkage type register, the Center Length of rotating shaft center to the outer end hinging shaft of the rocking arm of described all rotating shaft line the same sides is identical.
In above-mentioned a kind of differential linkage type register, described more than one rotating shaft is driven by power plant.
The utility model is compared the outstanding and beneficial technical effects of existing technology:
1, the utility model adopts differential connection, can realize the fine setting of air quantity.
2, the moment of opening of the register of the utility model reduces greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:
A kind of differential linkage type register, axially spaced-apart is equipped with some blades in the housing 1 of tubular, and vanes fixed is in the rotating shaft 2 perpendicular to housing 1 axis; Rotating shaft 2 is hinged on housing 1 wall, and an end of each rotating shaft 2 is fixed with rocking arm 3, and all rocking arms 3 are set in parallel in the same plane; It is characterized in that: all rocking arms 3 are divided into two groups of rocking arms 3 by the middle part to both sides; Two groups of rocking arms 3 are respectively in the both sides of all rotating shaft 2 lines, and the outer end of every group of rocking arm 3 is hinged on respectively on the kinematic link 4 of this group, wherein: one group of rocking arm 3 the most inboard rocking arm 3 extends to form second Rocker arm 5 to another group rocking arm 3 sides; Another group rocking arm 3 the most inboard rocking arm 3 is a fan-shaped rocking arm 6; The outer end of fan-shaped rocking arm 6 inboard 4 hinged with this group kinematic link, the outside is hinged with an end of differential connecting rod 7, the outer end of the other end of differential connecting rod 7 and described hinged second Rocker arm 5 is hinged, the utility model passes through the differential connecting rod 7 of fan-shaped rocking arm 6 connections; The outer end of the differential connecting rod 7 and second Rocker arm 5 is hinged; The speed governing that realized being in course of adjustment is stable, reduces the moment of rotation of register, can realize the fine setting of air quantity.
Is integral structure with this rocking arm 3 to extended second Rocker arm 5 of another group rocking arm 3 sides at one group of above-mentioned rocking arm, 3 the most inboard rocking arms 3.
Be connected on the bearing support 8 on the shell body wall in above-mentioned rotating shaft 2.
Center Length at rotating shaft 2 centers hinging shaft to the outer end of the rocking arm 3 of above-mentioned described all rotating shaft 2 line the same sides is identical.
