Abstract

The utility model discloses an LED (light emitting diode) street lamp sealing ring. The LED street lamp sealing ring comprises an annular sealing ring body (1), wherein an annular cavity (12) which circles around the sealing ring body (1) is formed in the sealing ring body (1) and is positioned in the center of the sealing ring body (1); the size of the cavity (12) is one fourth to two fifths of that of the sealing ring body (1); the thicknesses of parts, positioned on two sides of the cavity (12), of the sealing ring body (1) are greater than or equal to the thickness of a part, positioned on the top of the cavity (12), of the sealing ring body (1). When the LED street lamp sealing ring plays a sealing function, a connection structure between a street lamp base and a street lamp cover is favorably simplified on the existing basis, the magnitude of pre-tightening force applied to the connection structure is reduced, and the street lamp cover can be conveniently connected with or disconnected from the street lamp base.

Description

A kind of LED street lamp sealing ring

Technical field

The utility model relates to lighting device sealing ring field, particularly relates to a kind of LED street lamp sealing ring.

Background technology

LED light source is through the technique improvement of decades, high with its luminous efficiency, power consumption is few, long service life, security reliability is strong and be conducive to the advantages such as environmental protection, becomes modern lamplit main product.For stopping LED street lamp, be subject to out of doors the impact of rainwater or moisture under environment, sealing ring together with street lamp light cover has with operated by rotary motion on streetlamp lamp socket faying face.

The existing sealing ring applying on street lamp light cover and streetlamp lamp socket faying face generally adopts O type rubber seal, though the sealing ring of this kind of version can be realized the good sealing effectiveness of street lamp light cover and streetlamp lamp socket joint portion, but because solid structure and the inside and outside little characteristic of pressure reduction of LED street lamp own of O type rubber seal cross section, make need between street lamp light cover and streetlamp lamp socket, apply larger pretightning force when realizing excellent sealing effect, this just requires street lamp light cover and streetlamp lamp socket connecting portion to have good intensity and more binding site, this version is unfavorable for simplifying the structure of LED street lamp, be connected with streetlamp lamp socket or dismantle with inconvenient street lamp light cover.

Utility model content

For the version of sealing ring between above-mentioned existing street lamp light cover and streetlamp lamp socket, be unfavorable for simplifying the structure of LED street lamp, with the problem that inconvenient street lamp light cover is connected or dismantles with streetlamp lamp socket, the utility model provides a kind of LED street lamp sealing ring.

For addressing the above problem, a kind of LED street lamp sealing ring that the utility model provides solves problem by following technical essential: a kind of LED street lamp sealing ring, comprise the sealing ring body of ring-type, in described sealing ring body, be provided with along sealing ring body and cavity in the form of a ring, described cavity is arranged on the central authorities of sealing ring body, and the volume of cavity is in 1/4th to 2/5ths scopes of sealing ring bulk volume, and the thickness of cavity both sides sealing circle body is all not less than the thickness of cavity top seal circle body.

Concrete, to a cavity along the ring-type of sealing ring body be set on the sealing ring between street lamp light cover and streetlamp lamp socket, object is to reduce to make the needed compression of sealed ring deformation, the pretightning force reducing on the basis that is not provided with cavity between street lamp light cover and streetlamp lamp socket also can make sealing ring body reach original distortion or larger distortion, because own pressure reduction inside and outside LED street lamp is little, though this setting diminishes sealing ring local stress, can't affect sealing ring and bring into play its sealing property.And the performance that the larger deflection of sealing ring body can make sealing ring body adapt to out-of-flatness sealing surface strengthens, and make sealing surface reach more large deformation, not to be provided with the required pretightning force of cavity much smaller, like this, make sealing ring be conducive to simplify syndeton between streetlamp lamp socket and street lamp light cover during sealing function in performance on existing basis, reduce pretightning force size in syndeton, facilitate street lamp light cover be connected with streetlamp lamp socket or dismantle; And cavity is arranged on to the central authorities of sealing ring body, and make when sealing ring bears compression when realizing sealing that it does not cause its certain part aging permanent deformation at short notice to single Direction distortion, be conducive to service life of the present utility model; The setting of the relation of the setting of the shared sealing ring bulk volume of cavity and cavity side and positive face thickness, object is to make sealing ring body playing the ability that keeps suitable resistance to deformation in pressurized direction, is conducive to make the stable performance of its performance sealing.

Further technical scheme is:

The cross section of described sealing ring body is umbrella, and the top of umbrella cross section is the circle top that is fan-shaped, and at the bottom of the bottom of umbrella cross section is rectangular circle, and circle top is circular arc chamfering with joint portion, the corner at the circle end at the circle end; The cross section in the vertical direction of described cavity becomes center line symmetry, and the perpendicular bisector conllinear of line of symmetry and umbrella cross section.

This sealing ring body shape is simple in structure, there are not stress raisers when pressurized and cause premature breakage, at the bottom of the circle arranging for sealing ring body fixing on sealing surface, on sealing surface, be arranged at the groove of circle end profile coupling, so as with the installation of sealing ring body on sealing surface; And cavity is to make sealing ring when work both sides stressed evenly with respect to the object of the position relationship setting of cross section.

On described sealing ring body, be also provided with an angular cut, described angular cut with respect to the angular range of the cross section of angular cut place sealing ring body at 15 ° within the scope of 75 °.

The angular cut arranging on sealing ring body is applicable to difformity and big or small sealing surface for ease of the utility model, only need be set to band shape by sealing ring body in process of production, according to concrete utilization, cut the sealing ring body of certain length, angular cut is the combined mouth at sealing ring body two ends, and the setting of angle is intended to better realization along the sealing property of angular cut direction and obtains suitable angular cut width.

The utlity model has following beneficial effect:

The utility model is simple in structure, to a cavity along the ring-type of sealing ring body be set on the sealing ring between street lamp light cover and streetlamp lamp socket, object is to reduce to make the needed compression of sealed ring deformation, to obtain larger sealing ring body distortion amount under less compression, the performance that the deflection that sealing ring body is larger can make sealing ring body adapt to out-of-flatness sealing surface strengthens, and make sealing surface reach more large deformation, not to be provided with the required pretightning force of cavity much smaller, like this, make sealing ring when performance sealing function, be conducive to simplify the syndeton between streetlamp lamp socket and street lamp light cover on existing basis, reduce the pretightning force size in syndeton, facilitate street lamp light cover be connected with streetlamp lamp socket or dismantle.
