Abstract
The utility model provides a kind of and connects closely, assembly precision is high, heat preservation and insulation good and corner aluminum section bar attractive in appearance again.Technical solution adopted in the utility model is: a kind of corner aluminum section bar, and global sections is that right angle is fan-shaped; Described fan-shaped 3 angles are equipped with the right angle catching groove to fan-shaped inner recess, namely at the end of scallop respectively to fan-shaped inner side bending 90 °, then to fan-shaped outside bending 90 °, become 3 catching grooves at fan-shaped 3 dihedrals; Close on catching groove position at the two ends on described fan-shaped two limits and be respectively equipped with clamp; Described clamp top is provided with card base; Described fan-shaped two right-angle sides are respectively equipped with stopper slot.The advantage that the utility model has and good effect are: owing to adopting as above technical scheme, the utility model accurate positioning, and assembling is easy and precision is high, and connect closely, heat preservation and insulation is good, and good looking appearance.In addition, the utility model also has the advantage that structure is simple, be easy to processing.
Description
Technical field
The utility model relates to aluminium extruded sections, particularly relates to a kind of corner aluminum section bar.
Background technology
Compared with traditional door and window, alumium alloy door and window blast strength character, air leakage performance, rain leakage performance, air borne sound sound insulation property, heat preservation and insulation and start-stop performance etc. are all better, and alumium alloy door and window machining accuracy is high, for the standard-required such as energy-saving design and use safety of architectural exterior-protecting construction provides important and necessary condition.Corner aluminum section bar, as the connector of section bar, often becomes the short slab of doors and windows sealing, heat preservation and insulation, and affects attractive in appearance; Especially for location inaccurate, assembly precision is low, connect untight corner aluminum section bar, seriously will affect the combination property of alumium alloy door and window.
Summary of the invention
The utility model provides a kind of and connects closely, assembly precision is high, heat preservation and insulation good and corner aluminum section bar attractive in appearance again.
Technical solution adopted in the utility model is: a kind of corner aluminum section bar, and global sections is that right angle is fan-shaped; Described fan-shaped 3 angles are equipped with the right angle catching groove to fan-shaped inner recess, namely at the end of scallop respectively to fan-shaped inner side bending 90 °, then to fan-shaped outside bending 90 °, become 3 catching grooves at fan-shaped 3 dihedrals; Close on catching groove position at the two ends on described fan-shaped two limits and be respectively equipped with clamp; Described clamp top is provided with card base; Described fan-shaped two right-angle sides are respectively equipped with stopper slot.
As further improvement, described corner aluminum section bar is divided into inside lock cavity and outer corner cavity between described stopper slot and described fan-shaped drift angle; Between described inside lock cavity and described outer corner cavity, opposite flank is respectively equipped with dovetail groove; In described dovetail groove, heat insulating strip is installed.Wherein inside lock cavity is the isosceles right triangle cavity of fan-shaped top corner portion, and outer corner cavity is the cavity of the remaining close cambered surface part of fan-shaped deduction inside lock cavity portion and heat insulating strip place isosceles trapezoid part.
As preferably, described dovetail groove base angle is 40-50 °.
The advantage that the utility model has and good effect are: owing to adopting as above technical scheme, the utility model accurate positioning, and assembling is easy and precision is high, and connect closely, heat preservation and insulation is good, and good looking appearance.In addition, the utility model also has the advantage that structure is simple, be easy to processing.
Accompanying drawing explanation
Fig. 1 is corner aluminum section bar structural representation of the present utility model.
In figure: 1, catching groove; 2, card base; 3, clamp; 4, stopper slot; 5, inside lock cavity; 6, dovetail groove; 7, heat insulating strip; 8, outer corner cavity.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1, the present embodiment is a kind of corner aluminum section bar, is divided into inside lock cavity 5 and outer corner cavity 8; The side that inside lock cavity 5 is relative with outer corner cavity 8 is provided with the dovetail groove 6 that base angle is 45 °, is provided with heat insulating strip 7 in dovetail groove 6; Whole corner aluminum section bar cross section entirety is at right angles fan-shaped, wherein inside lock cavity 5 is the isosceles right triangle cavity of fan-shaped top corner portion, and outer corner cavity 8 is the cavity of the remaining close cambered surface part of fan-shaped deduction inside lock cavity 5 part and heat insulating strip 7 place isosceles trapezoid part; 3 angles of fan-shaped entirety are equipped with the right angle catching groove 1 to fan-shaped inner recess, namely at the end of scallop respectively to fan-shaped inner side bending 90 °, then to fan-shaped outside bending 90 °, become 3 catching grooves 1 at fan-shaped 3 dihedrals; Close on catching groove 1 position at the two ends on described fan-shaped two limits and be respectively equipped with clamp 3; Described clamp 3 top is provided with card base 2; Outer corner cavity 8 part of described fan-shaped two right-angle sides is respectively equipped with stopper slot 4.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
