Supporting structure for plastic part hot melting welding column

Abstract

The invention relates to a supporting structure for a plastic part hot melting welding column. The supporting structure is fixedly connected with a turning edge of a matching part. The supporting structure is composed of a supporting platform, a column platform and reinforcing ribs, wherein the supporting platform is composed of a straight stretching section and an outwards-extending section which are connected to form a whole body; the column platform is fixedly arranged in the center of the outwards-extending section of the supporting platform; the column platform is composed of a cylinder wall and an upper cover connected with the cylinder wall; a cavity structure is formed by the cylinder wall and the upper cover; a circular hole is formed in the center of the upper cover; the lower surface of the upper cover is vertical to the axis of a cylinder defined by the cylinder wall; the reinforcing ribs are fixedly connected with the left and right sides of the upper surface of the outwards-extending section; the reinforcing ribs extend to the outer appearance of the matching part from the front end of the outwards-extending section of the supporting platform and are connected with the straight stretching section of the outwards-extending section, the lower surface of the turning edge of the matching part and the outer appearance of the matching part. According to the supporting structure for the plastic part hot melting welding column, the contact area between the welding column and the supporting structure is enlarged and the supporting strength is improved; the supporting structure has the good assembling adaptability on a product with the large appearance curvature change.

Description

technical field [0001] The invention relates to a supporting structure used in the process of using a hot-melt welding column to fix two nested plastic plates, which can be widely used in the non-detachable connection of plastic material plates. Background technique [0002] The hot-melt welding column is a widely used matching structure in the fixed connection assembly of plastic parts. As a support arranged on the B surface (inner structural surface) of the product, its strength and assembly stability are given consideration during the design process. strict requirements. Such as figure 1 with figure 2 As shown, in the supporting structure of the prior art, a cylindrical tube 4a is fixed on the panel flange 4, and the hot-melt welding column fixed on the substrate passes through the cylindrical tube for hot-melt welding. This support structure has the following disadvantages: First, because the bottom surface of the flange is a slope with a changing curvature, it can o...

Problems solved by technology

This support structure has the following disadvantages: First, because the bottom surface of the flange is a slope with a changing curvature, it can only fit with the top surface of the welding post reinforcement, resulting in a small contact surface between the two. The matching stability of the hot-melt welding column is poor, and the friction noise between the parts is relatively large under the vibration state. Second, the support strength of the support structure is low. product fits well
