Abstract

The invention discloses a method for processing a waterproof joint on a processed lamp shell, which comprises the following steps: 1. arranging a through hole in the shell; 2. inserting a deformation part of the rivet nut into the through hole; 3. enabling a hand riveter to be inserted into an inner hole in the rivet nut from one end of a threaded connection part and to penetrate through one end of the deformation part, and fixedly connecting the pressing block to the end part of the hand riveter; 4. starting the hand riveter to pull the pressing block backwards so as to promote the pressing block to compact the deformation part, so that the deformation part bulges outwards to clamp the shell around the through hole between the bulge and the rivet nut compaction disk; and 5. mounting other waterproof components. The invention also discloses a rivet nut and a pressing block adopted in the method. By using the method and device, the rivet nut can have smaller caliber and smaller length, can have larger internal diameter than the traditional rivet nut under the condition of the same external diameter, and can penetrate through more wires, so that the lamp shell is more beautiful.

Description

technical field [0001] The invention relates to a blind rivet nut, which can be used for processing waterproof joints on lamp housings. The invention also relates to a method for processing the waterproof joint on the lamp housing by using the blind rivet nut. The present invention also relates to the pressing block used in the above method of processing the waterproof joint on the lamp housing by using the blind rivet nut. Background technique [0002] Traditional waterproof joints generally include a joint body with a compression plate, an outer thread on the outer end of the joint body, a nut with a gasket tightened on the outer end of the joint body, and a screw cap on the inner end of the joint body. An external thread, a fixed piece with an internal thread is screwed on the inner end of the joint main body, and the housing with the edge of the through hole is clamped between the two. However, the installation and manufacture of this waterproof joint is extremely inco...
