Abstract
The utility model relates to a corner connector for vent pipes of a central air conditioner, which belongs to building pipeline systems. Each corner connector comprises a first folded edge 2 and a second folded edge 3 which are upwardly folded at the edges of the corner connector 1, wherein two grooves 22 are respectively punched in the middles of two round-cornered edges of the corner connector 1; and a round hole 4 is formed at the round corner of the corner connector 1. By adopting the utility model, the connection between the corner connectors and the air pipes is stabilized, the positioning is more accurate, and the leak tightness of the vent pipe body is enhanced.
Description
Technical field
The utility model belongs to pipe-line system, is used in particular for a kind of joint angle sign indicating number of central air-conditioning ventilation duct.
Background technology
In order to save material, now a lot of ventilation ducts all form flanging at the sheet material two ends, the angle sign indicating number is arranged at four jiaos of airduct flanging respectively, and wrap the angle sign indicating number with flanging, form a flange like this, structurally simpler, but because light airduct flanging fixed corner code instability, can produce and become flexible, and sealing is not enough.
Summary of the invention
Being connected between the purpose of this utility model, firm angle sign indicating number and airduct flanging makes sign indicating number location, angle more accurate, and the sealing of reinforcement ventilation body.
Technical solution of the present invention is: a kind of angle sign indicating number that is used for the central air-conditioning ventilation duct, be included in first flanging and second flanging that the edge setting of described angle sign indicating number is upwards turned up, groove of punching press respectively at the middle part of two round edges of angle sign indicating number is provided with circular hole at the fillet place of described angle sign indicating number.The airduct flanging wraps first flanging, and second flanging closely contacts with the airduct body.
As preferably, the vertical height 5 ~ 8cm of described first flanging, the vertical height 5 ~ 8cm of described second flanging.
As further preferred, the angle of described first flanging and described angle sign indicating number is 85 ° ~ 100 °, and the angle of described second flanging and described angle sign indicating number is 90 ° ~ 110 °.
As further preferred, described groove forms projection at the reverse side of angle sign indicating number.Because groove is extruded by machine, so form projection naturally at the reverse side of angle sign indicating number, the projection of reverse side also can play positioning action at other positions like this.
As further preferred, the end face of two round edges of described angle sign indicating number is provided with chamfering, can reduce weight like this.
The utility model beneficial effect is: by first flanging on the sign indicating number of airduct flanging parcel angle, and at the groove that is provided with on the airduct flanging on the sign indicating number of the corresponding clamping of tongue angle, second flanging on the sign indicating number of angle is pressed on the airduct cylindrical shell, play sealing function, the angle code structure that is used for the central air-conditioning ventilation duct of the present utility model is simple, be connected more firmly with airduct, have good sealing property and stability.
Description of drawings

Fig. 2 is the utility model example structure schematic diagram.
Fig. 3 is the utility model embodiment structure schematic diagram.
Among the figure: 1-angle sign indicating number, 2-first flanging, 22-groove, 3-second flanging, 4-circular hole, 5-chamfering.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Embodiment: a kind of angle sign indicating number that is used for the central air-conditioning ventilation duct, be included in first flanging 2 and second flanging 3 that the edge setting of described angle sign indicating number 1 is upwards turned up, groove 22 of punching press respectively at the middle part of two round edges of angle sign indicating number 1 is provided with circular hole 4 at the fillet place of described angle sign indicating number 1.The vertical height 6cm of described first flanging 2, described first flanging 2 is 90 ° with the angle of described angle sign indicating number 1, the vertical height 8cm of described second flanging 3, the angle of itself and described angle sign indicating number 1 is 110 °, the airduct flanging wraps first flanging 2, there is the tongue correspondence to block groove 22 on the angle sign indicating number 1 on the airduct flanging, described groove 22 forms projection at the reverse side of angle sign indicating number 1, described second flanging 3 is wrapped on the airduct body, increase the sealing of ventilation duct, the end face of 1 two round edges of described angle sign indicating number is provided with chamfering, reduces the weight of angle sign indicating number 1.
