The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] An APU fire extinguishing nozzle installation and positioning tool, such as Figure 1 As shown, it includes an installation aluminum plate 1 and a digital display angle meter 2;

[0027] like Figures 2 to 5 As shown, the installation aluminum plate 1 includes a support plate 11 and a positioning frame 12. The positioning frame 12 is connected to the left side of the support plate 11. The positioning frame 12 and the support plate 11 form an L-shaped structure. A steel pad 13 is installed on the support plate 11. The digital display angle meter 2 is magnetically adsorbed on the steel pad 13. Positioning holes 14 are penetrated through the front and back of the positioning frame 12. The top and left side wall of the positioning frame 12 are threadedly installed with hexagonal resin bolts 15. The APU fire extinguishing nozzle 3 to be installed is inserted into the positioning hole 13 and locked by the hexagonal resin bolt 15. The structure of the APU fire extinguishing nozzle 3 is as shown in FIG. Figure 8 shown.

[0028] The material selection of the hexagon socket resin bolt 15 helps to protect the APU fire extinguishing nozzle 3 and avoid scratches on its surface.

[0029] A plurality of threaded holes 16 are evenly formed on the support plate 11, and a plurality of countersunk holes 17 are evenly formed on the steel backing plate 13. The threaded holes 16 and the countersunk holes 17 are arranged one by one, and hexagon socket countersunk bolts 18 are installed in the threaded holes 16 and the countersunk holes 17. The steel backing plate 13 is detachably mounted on the support plate 11 through the hexagon socket countersunk bolts 18. The steel backing plate 13 is designed as a detachable structure, which can be easily replaced and maintained.

[0032] The design of the first positioning hole 141 and the second positioning hole 142 is mainly based on the specific shape of the APU fire extinguishing nozzle 3. The side wall of the head end of the APU fire extinguishing nozzle 3 is fixed inside the first positioning hole 141 by the hexagonal resin bolt 15, and the second positioning hole 142 avoids the skirt structure at the lower part of the head end of the APU fire extinguishing nozzle 3.

[0033] An arc groove 19 is defined between the inner bottom wall and the inner right side wall of the first positioning hole 141 .

[0034] The positioning frame 12 is a square structure, and the first positioning hole 141 and the second positioning hole 142 at the rear side are both square holes.

[0035] The top and the left side wall of the positioning frame 12 are penetrated with mounting holes 110 , and the threaded rods of the hexagon socket resin bolts 15 are screwed into the corresponding mounting holes 110 .

[0036] The number of the threaded holes 16 and the number of the countersunk holes 17 are both three.

[0037] When the utility model is used Figure 6 , Figure 7 As shown, the digital display angle meter 2 is placed on the steel pad 13, and the digital display angle meter 2 is adsorbed on the steel pad 13 by its own magnetism. The square first positioning hole 141 of the tooling is covered on the front end of the APU fire extinguishing nozzle 3, and the hexagon socket resin bolt 15 is tightened to fix the APU fire extinguishing nozzle 3. The worker holds the entire tooling to adjust the APU fire extinguishing nozzle 3 to a suitable angle, tightens the nut of the APU fire extinguishing nozzle 3, and installs the APU fire extinguishing nozzle 3 on the bulkhead.

[0038] The utility model has the advantages of convenient installation, quick adjustment, compact structure and low manufacturing cost.

[0039] The utility model is described above by way of example in conjunction with the accompanying drawings.
