Description
Technical field
The present invention relates to one kind to be used for the rectangular piping connection Quick Release Hoop of aircraft.
Background technique
For the existing rectangular pipeline jointing construction form of aircraft as shown in Figure of description 1, pipeline passes through bulky bump joint
It is attached, just stamps a bolt hole every a distance on flange face, carried out tightly by bolt 10, washer 11, nut 12
Gu, it usually needs tens or up to a hundred a bolts, washer, nut are just able to achieve installation, and processing technology requires very high, installation
What hole location tolerance to be controlled very strict just can guarantee that bolt can be fully screwed into.This mounting means, dimensional tolerance are difficult to control
System, craftsmanship are poor；Accessibility is excessively poor, and dismounting is inconvenient, time and effort consuming.
Summary of the invention
The purpose of the invention patent is to provide a kind of air-conditioning duct square flange connection Quick Release Hoop.
The technical solution that the invention patent is taken are as follows:
A kind of air-conditioning duct square flange connection Quick Release Hoop, comprising:
Band 4, bolt 5, casing 6, washer 7, nut 8, retainer ring 9；
The both ends of band 4 and casing 6 and bolt 5 are attached by the mode for first passing through spot welding, and band 4 is straight by one block of metal
Plate is simultaneously welded and fixed through brake forming, both ends flange, and casing 6 is inserted into 4 one lateral flange corner of band, and it is another that bolt 5 is inserted into band 4
Lateral flange corner, band 4 wales retainer ring 9, and retainer ring 9 and band 4 are carried out circumferentially spot welding, and bolt 5 is inserted into casing 6, will pad
7 sets of circle pass through the part of casing 6 in bolt 5, and are tightened with nut 8.
The clip aims at rectangular piping connection and uses, and clip shape is rectangular.
4 corner turning radius of band need to be consistent with the radius of casing 6 and bolt 5
The size of band 4 and retainer ring 9 is adapted to the contour dimension of line flange 1,3.
Advantageous effects: using after the rectangular piping connection Quick Release Hoop, the installation maintenance process of pipeline is very convenient,
Rectangular Quick Release Hoop only has 1~2 bolt, it is only necessary to can easily realize quick connection disassembling with common spanner, subtract significantly
Light aircraft utilization maintenance workload.

Specific embodiment
The invention patent is described in further detail with reference to the accompanying drawings of the specification, please refers to Figure of description 2,3,4.
Rectangular air-conditioning duct is fastened by bolt 10, washer 11, nut 12 on existing aircraft, as shown in Figure 1, needing
Tens or up to a hundred a bolts, washer, nut are just able to achieve installation, and processing technology requirement is very high, and installation hole location tolerance is wanted
The very strict of control just can guarantee that bolt can be fully screwed into.This mounting means, dimensional tolerance are difficult to control, craftsmanship
Difference；Accessibility is excessively poor, and dismounting is inconvenient, time and effort consuming.
The invention patent provides a kind of for the rectangular piping connection Quick Release Hoop of aircraft, comprising: band 4, bolt 5, set
Pipe 6, washer 7, nut 8, retainer ring 9；
First have to the ruler that band 4 and retainer ring 9 are carried out according to the contour dimension of rectangular line flange 1,3 (pipeline concave-convex joint)
Very little design, it is ensured that retainer ring 9 can coincide with line flange 1,3；When clip assembles, the mode of spot welding is first passed through by the two of band 4
Head is attached with casing 6 and bolt 5, and by one piece of metal straight panel through brake forming, both ends flange is simultaneously welded and fixed, turns over band 4
Side corner reserves that certain space leaves casing 6 for respectively and bolt 5 carries out interspersed assembly, and corner turning radius need to be with casing 6
It is consistent with the radius of bolt 5, to guarantee that they can be bonded completely, avoid radial vibration.Casing 6 is inserted into 4 one lateral flange of band
Corner, bolt 5 are inserted into another lateral flange corner of band 4, and band 4 wales retainer ring 9, and retainer ring 9 and band 4 are carried out circumferentially point
Weldering, bolt 5 are inserted into casing 6, pass through the part of casing 6 in bolt 5 for 7 sets of washer, and tightened with nut 8.
The clip is a kind of hoop for pipeline connection, and product is quick-release type.The clip aims at rectangular piping connection and uses, clip
Shape is rectangular.
The V-type retainer ring 9 of clip compresses the inclined-plane of pipeline concave-convex joint when use, and two rectangular pipelines is enable closely to connect,
It is sealed between rectangular line flange 1,3 with sealing ring 2.Such as Fig. 2, Fig. 4.
The product is quick-release type clip, and dismounting working service is all very convenient, and clip major part part is all using existing
At standard component, processing and manufacturing mode and existing navigation mark, army's mark are consistent, and process for machining and manufacturing is good.
