Embodiment Construction

[0019] refer to figure 1 . In the embodiment described below, the clamping and fixing conical washer for distributing the load of the electronic equipment panel at multiple angles includes: a base 1 , a conical washer 2 , and a sleeve 3 . The bottom of the base 1 is equipped with a flat-bottomed circular counterbore 4 that is fitted with a round tubular tooling. The diameter of the sleeve 3 is smaller than the inner diameter of the flat-bottomed circular counterbore 4 and is integrally connected with the base 1. It extends upward to connect the conical washer 2. A notch is formed on the outer surface of the outer surface of the cone of the face washer 2 that is docked with the sleeve 3, and the inner surface of the bevel washer 2 is a conical counterbore 5 for installing a countersunk fastener for electronic equipment.

[0020] By adjusting the relevant dimensions of the base and the sleeve, it can be applied to equipment installation panels with different thicknesses and dif...

Abstract

The invention discloses a clamping fixing conical washer for multi-angle dispersion of an electronic equipment panel load and aims at providing the washer which is simple in structure, stable, reliable and capable of dispersing a load of a conical counter bore, and a multi-angle load dispersing method for combining and fixing a multilayer panel can be provided. According to the following technical scheme, the clamping fixing conical washer is characterized in that a base (1) and a sleeve (3) are integrally connected and fixedly connected to the base; the sleeve (3) penetrates through the conical counter bore (8) in the installation panel of electronic equipment, and the conical-surface washer (2) is formed in a spread out mode; and a lower-layer installation panel body (6) and an upper-layer installation panel body (7) are clamped between the conical-surface washer (2) and the step plane of the base (1), the conical-surface washer and a notch in the surface of the sleeve make contact with and interact with the upper-layer installation panel body and the lower-layer installation panel body, and thus an inlaid matching structure is formed. By means of the clamping fixing conical washer for multi-angle dispersion of the electronic equipment panel load, the pressure bearing area between a countersunk fastener and the equipment installation panel can be increased, so that the stress of the contact zone of the conical counter bore is dispersed to a certain extent.

Description

technical field [0001] The invention relates to a tapered washer mainly used for multi-angle dispersing panel loads of electronic equipment panels and a panel combination clamping and fixing method thereof. Background technique [0002] The installation of countersunk head fasteners on the panel of electronic equipment, in the current technical scheme, generally adopts the method of directly assembling the countersunk head fasteners by drilling holes in the installation panel. Because the material of the fastener is usually steel, and the material of the avionics equipment panel is often made of metal materials such as aluminum or non-metallic composite materials, this type of material is usually weak in strength, and because the countersunk fastener and the equipment installation panel The contact pressure bearing area of ​​the countersunk head fastener is small, and it is prone to wear or extrusion deformation during the assembly or use of the countersunk head fastener. U...
