[0021] The technical scheme of the utility model will be described clearly and completely below in combination with embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0022] Please refer to Figures 1-5As shown in the figure, a detachable small-diameter aviation conduit straight section shaping device includes a control end head 1, one end of the control end head 1 is used for shaping of the aviation conduit, the other end is connected with an adapter 2, and a handle 3 used for auxiliary shaping is further connected on the adapter 2. The adapter 2 is arranged so that the control end head 1 and the handle 3 are not in the same straight line, after the control end head 1 enters the inside of the narrow area on the aircraft, the handle 3 can be extended out to be held by the maintenance personnel as a force arm, thereby facilitating movement of the control end head 1.
[0023] Specifically, the control end head 1 includes a first threaded joint 6 and a shaping rod 4, one end of the first threaded joint 6 is connected with the end of the shaping rod 4, and the other end of the first threaded joint 6 is used for connection with the adapter 2. The outer wall of the first threaded joint 6 is further fixedly sleeved with a nut 5. The arrangement of the two parts of the control end head 1 can facilitate connection with the adapter 2 and achieve the shaping purpose. The arrangement of the nut 5 facilitates rotation of the first threaded joint 6 by using a wrench to turn the nut 5 when the first threaded joint 6 is connected with the adapter 2, thereby achieving threaded installation with the first threaded hole 8.
[0024] Specifically, an end seat is arranged at the connection between the shaping rod 4 and the first threaded joint 6, the end of the end seat away from the first threaded joint 6 is a conical surface, and the end of the shaping rod 4 away from the first threaded joint 6 is a spherical surface. The arrangement of the conical surface of the end seat makes the conical surface of the end seat coincide with the conduit bell mouth after the shaping rod 4 is inserted into the inside of the aviation conduit straight section, thereby ensuring that the conduit bell mouth is not damaged during in-flight shaping. The spherical surface arrangement of the end of the shaping rod 4 ensures that the conduit is not prone to abnormal deformation, bruising and other conditions during in-flight shaping.
[0025] Specifically, a first threaded hole 8 is arranged at the connection between the adapter 2 and the control end head 1, and the first threaded hole 8 is used for connection and installation of the first threaded joint 6.
[0026] Specifically, a second threaded joint 7 is connected with one end of the adapter 2 adjacent to the first threaded hole 8, and the second threaded joint 7 is used for connection and installation of the handle 3. A third threaded hole is formed in one end of the handle 3, and a second threaded hole 9 is formed in the side wall of the other end of the handle 3, and the two ends of the handle 3 can be connected with the second threaded joint 7 through the third threaded hole or the second threaded hole 9.
[0027] The handle 3 and the adapter 2 have two installation forms, the first installation form is as shown in the figure Figure 1 The third threaded hole at the end of the handle 3 is threadedly installed with the second threaded joint 7, and the second installation form is as shown in the figure Figure 2As shown, the second threaded hole 9 of the one end side wall of the handle 3 is screwed with the second threaded joint 7. Through the two kinds of installation, the handle 3 can respectively apply force upward and downward and leftward and rightward to the control end 1, and then the overall shaping of the aviation conduit can be realized, and different shaping requirements can be adapted. During use, one of the installation modes can be selected for use according to the requirements of the to-be-shaped and actual on-board operation environment, or the two modes can be alternately used.
[0028] In use, the control end 1 is screwed with the first threaded hole 8 of the adapter 2 through the first threaded joint 6, and the handle 3 is screwed with the second threaded joint 7 of the adapter 2 through the second threaded hole 9 or the third threaded hole. The diameter range of the aviation conduit suitable for the shaping device is 6-10 mm. When the straight section of the aviation conduit needs to be shaped, hold the handle 3 and insert the shaping rod 4 at one end of the control end 1 into the inside of the straight section of the aviation conduit. The shaping rod 4 is moved back and forth, rotated or forced to move in the inside of the straight section of the aviation conduit through the handle 3, or the straight section of the aviation conduit is forced to move, so that the shaping work of the straight section of the aviation conduit can be completed. After the shaping is completed, the whole device can be taken out from the on-board operation area.
