Description

Sealing ring of lamp shell of lighting lamp

Technical Field

The utility model relates to a sealing washer technical field, concretely relates to sealing washer of illumination lamps and lanterns lamp body.

Background

Outdoor light fixtures generally need to be rated for water resistance from the IP65 strong water spray test to the IP68 pressurized diving because outdoor weather is unpredictable and light, heavy and heavy rains are possible. If the waterproof measures of the lamp are not in place, the lamp is damaged, and the application effect is very poor. Consequently, require highly to the sealed effect of outdoor lighting lamps and lanterns lamp body, the sealing washer that adopts between the lamp body about the lamps and lanterns is mostly the cross section for circular seal ring at present, when using, because this kind of sealing washer is all less with the area of contact of lamp body from top to bottom, has the not good problem of sealed effect in the use, and in order to strengthen its sealed effect, can accomplish to be greater than seal groove cross section size with sealing washer cross section size, the installation of being not convenient for.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that when current sealing washer was used, the area of contact with the lamp body was not enough and the installation was inconvenient, provided a sealing washer of illumination lamps and lanterns lamp body, increased the area of contact of lamp body about sealing washer and the lamps and lanterns during the use, and the installation is simple.

In order to solve the technical problem of the utility model, the utility model discloses a realize through following technical scheme: the utility model provides a sealing washer of illumination lamps and lanterns lamp body, the sealing washer is applied to the sealing of illumination lamps and lanterns, illumination lamps and lanterns are including the last lamp body that has the seal groove and have the lower lamp body of protruding muscle, the sealing washer is arranged in the seal groove, the seal groove has tank bottom and cell wall, the sealing washer has well cavity, the afterbody both sides of sealing washer have protruding portion an and protruding portion b.

Preferably, the top of the sealing ring is in a shape which can be tightly attached to the groove bottom.

Preferably, the cross sections of the protruding part a and the protruding part b are axisymmetrical, and the protruding part a and the protruding part b are provided with outer surfaces close to the groove walls and inner surfaces close to the convex ribs.

Preferably, the included angle between the inner surfaces ranges from 50 degrees to 150 degrees.

Preferably, the height of the protruding part a and the protruding part b is 1-6 mm.

Compared with the prior art, the utility model discloses the beneficial effect who obtains is:

the utility model discloses a sealing ring of lamp shell of lighting lamp, which is characterized in that a hollow cavity and protruding parts are arranged on two sides of the tail part, when the upper and lower lamp shells are closed, the hollow cavity is extruded, the inner surfaces of the protruding parts are tightly attached to the convex ribs, and the contact area between the sealing ring and the convex ribs is increased; the shape of the top of the sealing ring is consistent with the groove bottom area of the sealing groove, and the sealing ring is attached to the groove bottom after being installed, so that the sealing property is improved; the protruding part is arranged, so that the convex rib of the lamp shell and the sealing groove are conveniently mounted in an occluded mode, and the production efficiency is improved.

Detailed Description

Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

Referring to fig. 1 to 5, the sealing ring 1 is applied to sealing a lamp housing of an illumination lamp, the illumination lamp includes an upper lamp housing 4 having a sealing groove 2 and a lower lamp housing 5 having a rib 3, the sealing ring 1 is disposed in the sealing groove 2, the sealing groove 2 has a groove bottom 21 and a groove wall 22, the sealing ring 1 has a hollow cavity 11, and two sides of a tail portion of the sealing ring 1 have a protrusion a121 and a protrusion b 122.

Further, the top of the sealing ring 1 is in a shape which can be tightly attached to the groove bottom 21.

Further, the cross sections of the protrusion a121 and the protrusion b122 are axisymmetrical, and the protrusion a121 and the protrusion b122 each have an outer surface 123 abutting against the groove wall 22 and an inner surface 124 abutting against the rib 3.

Further, the included angle between the inner surfaces 124 ranges from 50 degrees to 150 degrees.
