Description

Technical Field

[0001] The utility model relates to the technical field of aircraft installation auxiliary equipment, in particular to an auxiliary device for installing aviation system components in a narrow space. Background Art

[0002] When installing system components in a narrow space on an aircraft, especially threaded hexagonal screws, according to the shape of the screw head, the general operator will choose pliers with corresponding handles and jaws to twist the screw head. However, during the operation of such pliers with jaws, especially when an aviation system component, such as a screw, needs to be installed in a narrow space, the pliers either cannot reach the operating position, or after the jaws clamp the screw head, there is no space for the handle to swing due to space limitations. Even if the screw is tightened as much as possible, the angle problem when the jaws clamp the screw head due to space limitations will cause damage to the screw head. In addition, when rotating the screw head, if the force direction of the screw cannot be completely perpendicular to the screw axis, the screw rod will not be parallel to the mounting hole, which will not only make installation difficult, but also the screw cannot fully enter the mounting hole, resulting in the screw failing to achieve a locking effect. Therefore, an installation auxiliary tool that can rotate parts in a narrow space is needed to solve the above problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0018] Reference Figures 1 to 3 The auxiliary device for installing aviation system components in a narrow space shown in the figure comprises a ring sleeve 10 and a handle 20. A regular polygonal sleeve hole 11 is arranged inside the ring sleeve 10, and a plurality of through holes 12 are arranged on the outer periphery of the ring sleeve 10. The ring sleeve 10 is located on the outer periphery of the sleeve hole 11 and a plurality of clamping holes 13 are arranged along the axial direction of the sleeve hole 11; a fork 21 is arranged at one end of the handle 20, and the two forks of the fork 21 can be respectively matched with any two clamping holes 13, and a hook 22 matched with the through hole 12 is arranged at the other end of the handle 20. Both ends of the handle 20 can be operated, and it is adapted to different working conditions and has strong adaptability. A structure that can rotate around the handle 20 body is formed between the fork 21 and the handle 20 body. Such a structure can use one end of the hook 22 as a force arm to drive the fork 21 to rotate around the handle 20 body, and then drive the ring sleeve 10 to rotate.

[0019] In addition, in the above-mentioned embodiment, the size of the ring sleeve 10 is fixed, and it is generally adapted to nut parts within a certain diameter specification. The purpose of this is to limit the outer diameter of the ring sleeve 10, which is conducive to use in a narrow space. For this reason, in actual use, bushings with different apertures can be arranged in the sleeve hole 11 to adapt to nuts of different specifications.

[0020] See also Figure 1 and Figure 2 The handle 20 includes a straight rod 23, a hook head 22 and a fork head 21 are respectively arranged at both ends of the straight rod 23, and a deformable bending portion 24 is arranged between the straight rod 23 and the hook head 22, and the deformable bending portion 24 can only be bent along the plane formed by the hook head 22 and the straight rod 23. Among them, the main purpose of the deformable bending portion 24 is to adapt to the shape of the ring sleeve 10, increase the force point, and facilitate the straight rod 23 to drive the end close to the hook head 22 to rotate around the rotation center of the parts.

[0021] In some possible implementations, in order to adapt to the outer diameters of the ring sleeves 10 of different sizes, the deformable curved portion 24 is formed by hingedly connecting a plurality of connecting segments in sequence. Such a purpose can be that the deformable curved portion 24 can adapt to the outer diameters of the ring sleeves 10 of different sizes.

[0022] In some possible implementations, in order to prevent the sharp edges of the ring sleeve 10 from scratching the parts when the ring sleeve 10 is adapted to the parts, all the edges on the ring sleeve 10 are provided with chamfers.

[0023] See also Figure 3 In order to better fit the parts, which are generally nuts in this application, six through holes 12 and six clamping holes 13 are provided to facilitate the rotation of the parts. The clamping holes 13 are evenly arranged on the corresponding areas of the ring sleeve 10 located on the outer periphery of the sleeve hole 11, and the two forks of the fork head 21 are respectively adapted to the two clamping holes 13 in the radial direction of the sleeve hole 11.

[0024] Similarly, the cross section of the sleeve hole 11 is a regular hexagon, and all the clamping holes 13 are respectively arranged on the corresponding areas of the ring sleeve 10 located at the corner tips of the sleeve hole 11. The fork head 21 is U-shaped.

[0025] The auxiliary device for installing aviation system components in a narrow space adopts a split design, using a ring sleeve 10 to adapt to the parts that need to be rotated, and then using a handle 20 to drive the ring sleeve 10 to rotate, and two different driving modes are designed respectively. The matching of the fork head 21 and the clamping hole 13 is suitable for the driving mode along the axial direction of the ring sleeve 10, and the matching mode of the hook head 22 and the through hole 12 is suitable for the traditional circumferential driving mode, which are respectively adapted to different use environments and improve the convenience of use.

[0026] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
