Detailed Description

For a clearer understanding of the objects, technical solutions and advantages of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

FIG. 1 is a cross-sectional view schematically showing the construction of the quick release carrier of the present invention. The quick-release bearing device can be applied to the connection of an aviation suspension device and airplane wings, and can effectively bear the heading, lateral and vertical forces of an airplane. As shown in the figure, the quick-release bearing device comprises a mounting seat 1, a stop washer 2, an elastic clamping piece 3, a bolt 4 and a bearing joint 5. When the aircraft suspension device is used, the mounting base 1 is fixed on the wing, and the bearing joint 5 is fixed on the aircraft suspension device.

The bearing joint 5 is placed in a placing hole in the mounting seat 1 and is connected with the bearing joint 5 through the bolt 4, the contact surface of the bearing joint 5 and the placing hole in the mounting seat 1 can bear the heading force and the lateral force of the airplane, and the vertical force is borne by the bolt 4. In this embodiment, the two ends of the carrier joint 5 are both cylindrical surfaces, and the middle part is a tapered surface (see fig. 6), which is convenient for guiding when being placed in the placing hole, and in addition, the cylindrical surfaces at the two ends are easy to ensure the assembling precision. Accordingly, the shape of the placement hole in the mounting socket 1 corresponds to the outer shape of the carrier tab 5, as shown in fig. 2.

The quick-release bearing device has a mechanical locking function, a clamping block is arranged at the lower part of the locking washer 2, and the clamping block can be fixed in a fixing groove (see figure 2) arranged on the mounting seat 1 to prevent the locking washer 2 from rotating; the upper part of the stop washer 2 is provided with evenly distributed stop grooves, and the structure of the stop washer 2 is shown in figure 3. As shown in fig. 4, the elastic clamping piece 3 is a U-shaped structure, the end of the vertical arm is provided with a bending structure protruding outwards, the middle of the cross arm extends along the direction perpendicular to the cross arm to form a long tongue end, the long tongue end is fixed in the locking groove of the locking washer 2 to prevent the elastic clamping piece 3 from rotating, the vertical arm of the elastic clamping piece 3 is fixed in the hexagonal hole of the head of the bolt 4, the vertical surface of the vertical arm contacts with two parallel surfaces opposite to the hexagonal hole in the bolt 4 to prevent the bolt 4 from rotating, the bending structure at the end of the vertical arm is located in the cavity below the hexagonal hole in the bolt 4 to prevent the elastic clamping piece 3 from moving up and down, and the structure of the bolt 4 is shown in fig. 5. The purpose of stopping the quick-release bearing device is achieved under the combined action of the mounting seat 1, the stop washer 2, the elastic clamping piece 3 and the bolt 4.

In addition, the load-bearing joint 5 and the mounting base 1 are preferably made of the same material, and may be made of ultra-high-strength steel, and more specifically, 30CrMnSiNi2A ultra-high-strength steel. In addition, the material of the elastic card 3 may be spring steel, and specifically may be 65Mn spring steel.

Among the quick-release bearing device, bearing joint 5 passes through lock washer 2, elasticity card 3, bolt 4 fixed connection on mount pad 1, does not use locking modes such as beating the fuse, rubber coating, can dismantle fast, and is easy and simple to handle swift.
