A kind of air port
Technical field
The present invention relates to a kind of idle call member, particularly air port.
Background technology
Existing air port generally is by four outer frame bodies, be end-to-end together corner brace, the fixing dihedral jump ring in angle after adjacent two outer frame bodies are connected of four outer frame bodies is consisted of.This kind dihedral jump ring generally be with special steel punching press and heat-treat, the processing such as blackout, like this, just can make it have good elasticity and antiseptic property, therefore, its manufacturing process is complicated, manufacturing cost is high, and, determined by its environment for use, after use a period of time, in the situation of the continuous variation of humiture, gather condensed water on its surface easily and cause the appearance of corrosion.
Summary of the invention
Goal of the invention of the present invention is to provide the air port that a kind of member manufacturing process that angle after the adjacent two outer frame bodies connection is fixed is simple, cost is low, can not cause the corrosion appearance.
The present invention realizes like this, comprise housing, be arranged on several pieces air port blades in the housing, housing comprises four outer frame bodies, with four outer frame bodies be end-to-end together corner brace, the fixing member in angle after adjacent two outer frame bodies are connected, its special feature is that member is a square plastic sheath, be provided with bayonet socket on adjacent two outer frame bodies of corresponding square plastic sheath two outer side edges, the two orthogonal limits cover of square plastic sheath is enclosed within on adjacent two outer frame bodies separately, and square plastic sheath two outer side edges are inlayed respectively in the bayonet socket set on adjacent two outer frame bodies.Because the square plastic sheath has reasonable extension elasticity, therefore, the square plastic sheath can be stuck on adjacent two outer frame bodies in interference, guarantee that adjacent two outer frame bodies connect closely, determined by the character of square plastic sheath, compared with the prior art technology of the present invention obviously has the advantage that the member manufacturing process that the angle after the adjacent two outer frame bodies connection is fixing is simple, cost is low, can not cause the corrosion appearance.
Here, come off in order to prevent the square plastic sheath, the barb that the one side on square plastic sheath two outer side edges or two sides are provided with evagination is provided with barb button mouth on the limit on one side of set bayonet socket inboard or both sides on the outer frame body of corresponding barb.Like this, the barb by evagination is embedded in barb button mouth set on the bayonet socket inner side edge, has prevented that the square plastic sheath from coming off.
Several pieces air port blades that are arranged on the internal orifice place in the housing are connected with the Power Drive Unit with control device, Power Drive Unit comprises the motor that is fixed on the support, the gear that links to each other with motor, the transmission connecting rod mechanism that links to each other with gear, several pieces air port blades at the internal orifice place that transmission connecting rod mechanism is interior with being arranged on housing are connected, output shaft at gear is connected with potentiometer, the signal of telecommunication output of potentiometer links to each other with the signal of telecommunication input of control device, and the signal of telecommunication output of control device links to each other with the driving signal of telecommunication input of Power Drive Unit.During work, the angle of measuring the swing of kinematic link by the output resistance of potentiometer is determined the rotational angle of air port blade then, controls the size of the air output in air port.Adopted potentiometer, can make control device simple, and, can be reliably and effectively realize the quantitative control of air quantity.
The present invention compared with the prior art, have that the fixing member manufacturing process in angle after adjacent two outer frame bodies are connected is simple, cost is low, can not cause that corrosion occurs, control simply, reliably, advantage easily.

The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is done and describes in further detail:
Such as Fig. 1, shown in 2, the present invention includes housing 1, be arranged on several pieces air port blades 2 in the housing 1, housing 1 comprises four outer frame body 1a, with be end-to-end together corner brace 3 of four outer frame body 1a, with the fixing member 4 in angle after the adjacent two outer frame body 1a connection, its special feature is that member 4 is square plastic sheaths, be provided with bayonet socket 5 on the adjacent two outer frame body 1a of 4 liang of outer side edges 4a of corresponding square plastic sheath, two orthogonal limit cover 4b of square plastic sheath 4 are enclosed within on the adjacent two outer frame body 1a separately, and 4 liang of outer side edges 4a of square plastic sheath inlay respectively in the upper set bayonet socket 5 of adjacent two outer frame body 1a.
Be provided with barb button mouth 5a on the limit on one side of set bayonet socket 5 inboards or both sides on the barb 4c that one side on 4 liang of outer side edges 4a of square plastic sheath or two sides are provided with evagination, the outer frame body 1a of corresponding barb 4c.
As shown in Figure 3, several pieces air port blades 2 that are arranged on the internal orifice 1b place in the housing 1 are connected with the Power Drive Unit 7 with control device 6, Power Drive Unit 7 comprises the motor 7a that is fixed on the support 8, the gear 7b that links to each other with motor 7a, the transmission connecting rod mechanism 7c that links to each other with gear 7b, transmission connecting rod mechanism 7c is connected with several pieces air port blades 2 at internal orifice 1b place in being arranged on housing 1, output shaft at gear 7b is connected with potentiometer 9, the signal of telecommunication output of potentiometer 9 links to each other with the signal of telecommunication input of control device 6, the signal of telecommunication output of control device 6 links to each other with the driving signal of telecommunication input of Power Drive Unit 7, be provided with housing sealing joint strip 10 in housing 1 inboard, be arranged on the edge of several pieces air port blades 2 at the internal orifice 1b place in the housing 1 runner sealing adhesive tape 11 is set.
