Description

Technical Field

[0001] This utility model belongs to the field of installation parts technology, specifically relating to an adaptive washer and a workpiece oblique mounting structure. Background Technology

[0002] Currently, known fastening washers include flat washers and elastic washers. Flat washers prevent the screw head from directly contacting the mounted component, thus avoiding damage to its surface. Elastic washers, after tightening, are also compressed into a flat state. In addition to the functions of flat washers, elastic washers also prevent slippage. Both types of washers are used for components mounted on flat surfaces. For components mounted at an angle, bevel washers are also used, but they can only be used when the angle of the bevel matches the angle of the mounting surface. When the angle of the mounting surface changes, the bevel of the washer must also change accordingly; otherwise, it is not applicable and lacks versatility. For components mounted at an angle, riveting is also used for fixing. Riveting requires equipment and tooling, significantly increasing process costs, and is relatively inefficient when the number of fasteners is small. Therefore, obtaining an adaptive washer and a workpiece oblique mounting structure is crucial. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, an adaptive washer and a workpiece oblique mounting structure are provided.

[0004] On the one hand, this utility model provides an adaptive washer, comprising: Washer body; At least one adaptive support structure is formed on the washer body, the adaptive support structure including at least one leg, the leg having a limiting portion for contacting the workpiece to be installed, the limiting portion having a rounded side for contacting the workpiece to be installed, so as to be able to adapt to the workpiece being installed being pressed and limited at different angles.

[0005] The arc surface extends along the thickness direction of the limiting part, so that the part on the arc surface that is used to abut against the workpiece being installed is linearly arranged along the thickness direction of the limiting part.

[0006] The limiting portion on the support leg forms an arc surface to achieve tight clamping and limiting of the installed workpiece at different angles.

[0007] Each set of adaptive support structures has two legs, which are symmetrically arranged on both sides of the washer body with the center of the washer body as the axis of symmetry.

[0008] The two legs of this utility model form a clamping structure. The arc surface of the limiting part is in linear contact with the workpiece to be installed. The clamping force is applied to the adaptive washer through the end face of the fastener, and then transmitted to the inclined surface of the workpiece to be installed through the legs, so as to clamp the workpiece and fasten the workpiece to the mounting plate.

[0009] A fastener through hole is formed through the main body of the washer. A limiting ring is provided at the top of the fastener through hole, and the inner hole of the limiting ring is coaxial with and connected to the fastener through hole. A keyway is formed on the inner wall of the fastener through hole, which can prevent the rotation of the self-adaptive washer and maintain the uniform force applied to the pressure points of the symmetrical support legs.

[0010] At least one groove is formed on the circumference of the surface of the washer body.

[0011] On the other hand, this utility model provides a workpiece oblique mounting structure, including a mounting plate, fasteners, a workpiece, and the aforementioned adaptive washer. The mounting plate is provided with at least one mounting protrusion, and the workpiece has a mounting hole for the mounting protrusion to pass through. The adaptive washer is sleeved on the mounting protrusion. The connecting part of the fastener passes through the fastener hole of the adaptive washer and is fixedly connected to the mounting protrusion. The head of the fastener is pressed against the top of the adaptive washer sleeve to fix the adaptive washer to the mounting protrusion. The slope of the mounting inclined surface on the mounting plate is 0-45 degrees.

[0012] The mounting plate is provided with a step, which abuts against the periphery of the workpiece to limit the workpiece being mounted; the mounting protrusion is provided with a key body that mates with the keyway, and the key body is inserted into the keyway for radial limitation.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model has a simple structure and overcomes the limitations of existing flat washers and fixed-angle inclined washers in securing components with changed tilt angles. Therefore, the adaptive washer of this utility model can secure not only components mounted on a flat surface but also components with changed tilt angles. The adaptive washer provided by this utility model can secure components with various mounting tilt angles.

[0014] This invention's adaptive washer, under the locking force of the fastener, can securely fasten tilted workpieces, with a wide applicable tilt angle range of 0-45°. It features a simple structure, strong versatility, and excellent fastening effect, meeting the requirements of 11 random vibration tests in the national standard (GB10485).
