Description

Sealing structure of electrical cavity of LED lamps

Technical Field

The utility model relates to a lighting device technical field especially relates to the seal structure in the electrical chamber of kinds of LED lamps and lanterns.

Background

An electrical cavity is usually arranged on the LED lamp and used for installing electric devices such as a power supply and the like, so the electrical cavity needs to be sealed by a sealing ring, the conventional sealing ring is arranged between a lamp body and a lamp cover, the sealing ring is compressed up and down to deform to realize sealing, the resistance is large when the lamp cover is closed, and the operation is inconvenient; the influence of the flatness of the lamp cover is large, and the sealing failure phenomenon is easy to occur; moreover, the sealing mode has poor sealing effect and low sealing grade.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the background art, the utility model provides a sealing structure of kinds of LED lamp electrical cavities, an electrical cavity upper cover is provided with a upper cover, the sealing structure comprises a raised sealing rib arranged on the electrical cavity ring, a sealing ring sleeved on the sealing rib, and a sealing groove arranged at the position of the upper cover corresponding to the sealing rib;

the upper cover is covered on the electrical cavity, the sealing rib extends into the sealing groove, and the sealing ring is pressed between the sealing rib and the sealing groove.

Preferably, a clamping groove is formed in the ring of the sealing ring, and the sealing ring is sleeved on the sealing rib through the clamping groove.

Preferably, a sealing tongue protruding into the clamping groove is arranged on the side wall of the clamping groove, the sealing rib drives the sealing ring to be clamped into the sealing groove, and the sealing tongue is extruded between the inner side wall of the sealing groove and the sealing rib.

Preferably, the thickness of the side wall of the sealing ring provided with the sealing tongue is gradually increased from side of the groove bottom of the clamping groove to side.

Preferably, a gap is left between the groove bottom of the sealing groove and the top of the sealing ring.

The utility model discloses owing to adopt above technical scheme, make it compare with prior art, have following advantage and positive effect:

the utility model provides a seal structure in electrical chamber of LED lamps and lanterns stretches into the seal groove through sealed muscle in, the rethread sealing washer sticiss at seal groove and sealed muscle to realized sealed, this kind of sealed mode only realizes sealed mode through the sealing washer among the prior art, and sealed effect is higher.

Drawings

The above and other features and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic view of an electrical cavity in an open state of an upper cover of the present invention;

fig. 2 is a cross-sectional view of the electric cavity after the upper cover is closed;

FIG. 3 is an enlarged view of a portion of FIG. 2 at A;

fig. 4 is a cross-sectional view of the middle seal ring of the present invention.

Detailed Description

The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

Referring to fig. 1-4, the utility model provides a seal structure in electrical chamber of kinds of LED lamps and lanterns, seal structure is including setting up bellied sealed muscle 6 on electrical chamber 2 circles, cover and establish the sealing washer 3 on sealed muscle 6, set up at the seal groove 5 of upper cover 1 and the corresponding position department of sealed muscle 6, the upper cover 1 lid is established on electrical chamber 2, sealed muscle 6 stretches into in the seal groove 5, seal ring 3 presses between sealed muscle 6 and seal groove 5.

The utility model provides a seal structure in electric chamber stretches into in the seal groove through sealed muscle, and rethread sealing washer sticiss at seal groove and sealed muscle to realized sealed, this kind of sealed mode only realizes sealed mode through the sealing washer among the prior art, and sealed effect is higher.

In this embodiment, referring to fig. 3-4, the sealing ring 3 is U-shaped, a clamping groove 301 is formed on the ring , and the sealing ring 3 is sleeved on the sealing rib 6 through the clamping groove 301.

In the embodiment, referring to fig. 4 again, the side wall of the slot 301 is provided with the sealing tongue 302 protruding into the slot, when the upper cover 1 is closed, the sealing rib 6 drives the sealing ring 3 to be clamped into the sealing groove 5, the inner side wall of the sealing groove 5 presses the outer side wall of the sealing ring, the sealing tongue 302 is pressed between the inner side wall of the sealing groove 5 and the sealing rib 6, the sealing tongue 302 appears, and the sealing of the electrical cavity is realized.

, referring to fig. 4 again, the thickness of the side wall of the sealing ring 3 provided with the sealing tongue 302 increases gradually from side to side of the bottom of the clamping groove 301, so that the side sealing effect is enhanced by steps.

In the embodiment, a gap 7 is left between the groove bottom of the sealing groove 5 and the top of the sealing ring 3, so that only the left side and the right side of the sealing ring are deformed to seal after the upper cover is closed; the top of the sealing ring 3 is not in contact with the upper cover 1, so that the resistance caused by the deformation sealing form of the top of the sealing ring (the lamp cover and the top of the sealing ring are extruded and deformed) when the upper cover is closed is reduced, and the upper cover is more smoothly opened and closed; the sealing ring 3 of the embodiment adopts side sealing, and sealing failure caused by deformation of the upper cover or the sealing ring fixing rib when the sealing ring 3 adopts a top deformation sealing mode is also avoided.

It will be appreciated by those skilled in the art that the invention can be embodied in many other specific forms without departing from the spirit or scope of the invention. Although embodiments of the present invention have been described, it is to be understood that the invention is not limited to those embodiments, and that changes and modifications may be made by one skilled in the art within the spirit and scope of the invention as defined in the appended claims.
