Abstract

The invention discloses a lamp waterproof device. The lamp waterproof device comprises a lamp base body, wherein an accommodating slot and a line piercing hole are formed in the lamp base body; a protective sealing ring and a limiting body used for contacting and protecting the sealing ring are arranged in the line piercing hole, a spinning bolt is arranged on the lamp base body, and a bolt threadhole is formed in the spinning bolt; the spinning bolt comprises a bolt head and a bolt threaded section; the bolt threaded section extends into the line piercing hole, and is in threaded fit to theline piercing hole; the protective sealing ring is positioned between the limiting body and the spinning bolt; and the head of the bolt is located outside the accommodating slot. The lamp waterproof device has the beneficial effects that: the structure is reasonable, accommodating of a car lamp light source and piercing of an electric line can be realized, the electric line and a line hole can beeffectively sealed, and water and dust can be guaranteed to not enter the car lamp; and the protective sealing ring is internally thick and externally thin, and inner deformation amount of the sealingring is relatively great under action of pressure, so that the sealing ring can be in sealing and contact with the electric line which passes through the sealing ring better, and therefore, the lampwaterproof device has a good sealing effect.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a waterproof device for lamps. Background technique [0002] Car lights (such as car headlights, taillights, turn signals, etc.) refer to the lamps on the vehicle. tooltip. Automobile lights usually include lamp holders, lampshades, car light sources (such as tungsten-halogen bulbs, LED lamp beads, etc.) and wires and other structures. It is a sealed connection, and the wire needs to pass through the wire hole on the lamp holder. However, water vapor, dust, etc. can easily enter the interior of the lamp from the wire hole, thereby affecting the effect of the lamp. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a reasonable structure, which can realize the accommodation of the light source of the car light and the perforation of the wire, and the effective sealing between the wire and the wire hole ...
