[0020] The following combines the attachedFigure 1 、 Appendix Figure 2 、 Appendix Figure 3 Further description of the present utility model is provided as follows.

[0021] An auxiliary tooling for quickly removing and installing a quick-release joint of an aircraft galley oven water pipe, comprising:

[0022] A fixed handle 1, with an arc-shaped slot II 20 provided at its head end; a movable handle 5, rotatably connected to the fixed handle 1 in an X shape through a rotating mechanism. An arc-shaped slot I 11 is provided at the head end of the movable handle 5. Slot I 11 and slot II 20 combine to form a circular hole matching the outer diameter of the telescopic head end 14 of the quick-release joint of the aircraft galley oven water pipe. A baffle 12 is provided at the outer end of slot I 11. When the telescopic head end 14 is clamped in the circular hole, the outer end face of the telescopic head end 14 contacts the inner end face of the baffle 12; a sliding seat 7, the fixed handle 1 is slidably installed in the sliding seat 7 through a sliding mechanism. A fork head 10 is installed at the head end of the sliding seat 7. A U-shaped groove 13 is provided in the fork head 10, and the width of the U-shaped groove 13 matches the outer diameter of the joint groove 15 of the quick-release joint of the aircraft galley oven water pipe. When the telescopic head end 14 is clamped in the circular hole, the U-shaped groove 13 of the fork head 10 is inserted at the joint groove 15. When it is necessary to remove the quick-release joint of the aircraft galley oven water pipe, after inserting the U-shaped groove 13 of the plug 10 at the joint groove 15, the fixed handle 1 is slid through the sliding mechanism until the telescopic head end 14 is placed in the slot II 20, and the movable handle 5 is rotated through the rotating mechanism until the upper end of the telescopic head end 14 is located in the slot I 11 to clamp the telescopic head end 14. The outer end of the telescopic head end 14 contacts the baffle 12. Then, the fixed handle 1 is slid inward through the sliding mechanism. Since the baffle 12 limits the outer end of the quick-release joint of the aircraft galley oven water pipe and the fork head 10 limits the joint groove 15 of the quick-release joint of the aircraft galley oven water pipe, the telescopic head end 14 slides inward to be in a compressed state. At this time, the quick-release joint of the aircraft galley oven water pipe can be pulled out from the water pipe. The disassembly and installation efficiency and accuracy of the quick-release joint of the aircraft galley oven water pipe are improved.

[0023] When it is necessary to install the quick-release joint of the aircraft galley oven water pipe, repeat the above actions. After the telescopic head end 14 is in a compressed state, with the assistance of the entire auxiliary tooling, place the quick-release joint of the aircraft galley oven water pipe in the compressed state of the telescopic head end 14 at the water pipe nozzle of the oven, insert the quick-release joint of the aircraft galley oven water pipe into the water pipe, and then remove the entire auxiliary tooling from the quick-release joint of the aircraft galley oven water pipe. The telescopic head end 14 is not in a compressed state, and at this time, the quick-release joint of the aircraft galley oven water pipe is locked with the water pipe.

[0024] In an embodiment of the present utility model, the rotating mechanism includes an ear seat I 2 provided on the fixed handle 1, and a bolt I 4 passes through the ear seat I 2 and the movable handle 5 in sequence and is locked by a nut 3. Using the bolt I 4 as a rotating shaft, the movable handle 5 can rotate relative to the fixed handle 1 around the bolt I 4, and the structure is simple.

[0025] In an embodiment of the present utility model, it further includes a locking ring 6 rotatably installed at the tail end of the fixed handle 1. When the telescopic head end 14 is clamped in the round hole, the locking ring 6 rotates to hook on the tail end of the movable handle 5. At this time, the fixed handle 1 and the movable handle 5 are locked and fixed relative to each other. The operator does not need to always hold the fixed handle 1 and the movable handle 5 tightly by hand to clamp the telescopic head end 14, which further improves the operation convenience and reduces the labor intensity.

[0026] In an embodiment of the present utility model, the sliding mechanism includes N bolts II 16. The bolts II 16 are screwed into the sliding seat 7, and the axis of the bolts II 16 is arranged in the horizontal direction. The fixed handle 1 is provided with through holes matching the bolts II 16, and the bolts II 16 are inserted into the through holes. The bolts II 16 act as guide shafts, and the fixed handle 1 can slide along the bolts II 16 to realize the pressing operation of the telescopic head end 14. In this embodiment, N is a positive integer greater than or equal to 2. Arranging more than 2 bolts II 16 can enable the sliding seat 7 to slide left and right along the bolts II 16 without rotation.

[0027] In an embodiment of the present utility model, it further includes an adjusting column 17 installed at the lower end of the fixed handle 1 and a sliding groove 18 provided at the bottom of the sliding seat 7. The length direction of the sliding groove 18 is parallel to the axis of the quick-release joint of the water pipe of the aircraft galley oven. The axis of the adjusting column 17 is arranged in the vertical direction, and the adjusting column 17 is slidably inserted into the sliding groove 18. Through the adjusting column 17, the operator can conveniently drive the fixed handle 1 to slide left and right by using it. The adjusting column 17 slides in the sliding groove 18, and the sliding groove 18 plays a guiding role.

[0028] In an embodiment of the present utility model, it further includes an ear seat II 8 installed at the lower end of the sliding seat 7 and a locking block 9 rotatably installed at the lower end of the sliding seat 7. A long hole 19 is provided in the locking block 9. When the fixed handle 1 slides inwards until the telescopic head end is in a compressed state, the locking block 9 rotates until the adjusting column 17 is inserted into the long hole 19. When the fixed handle 1 is driven by the adjusting column 17 to move inwards relative to the movable handle 5 to make the telescopic head end 14 in a pressed state, the locking block 9 is rotated. After the adjusting column 17 is inserted into the long hole 19, the adjusting column 17 contacts the outer end of the long hole 19. At this time, the adjusting column 17 cannot move outwards anymore, and the telescopic head end 14 can always maintain a pressed state, which is convenient for the disassembly and installation of the quick-release joint of the water pipe of the aircraft galley oven, and prevents the operator from always pressing the fixed handle 1 inwards under the action of the spring force of the telescopic head end 14, further improving the operation convenience and use comfort.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
