Description

LED stretches underground lamp

Technical field

The utility model is related to a kind of LED, and in particular to a kind of LED stretches underground lamp.

Background technology

In town road and some garden paths, it will usually which underground lamp is set, underground lamp due to concordant with ground, because This pedestrian passes by or has vehicle by can be rolled by underground lamp, therefore the lamp surface intensity of underground lamp must assure that, but long Phase is pressurized, and the intensity of whole lamp body can be reduced slowly, and last LED underground lamp is damaged, and can be saved bit by bit on the glass surface of underground lamp A large amount of dusts, cause light emission rate to reduce.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of ash that can effectively remove transparent glass layer upper end Dirt, while setting elastic parts can effectively solve the problem that the problem that the long-term stress of underground lamp is damaged.

The utility model is achieved through the following technical solutions：A kind of LED stretches underground lamp, including a shell body with And the inner housing inside shell body is set in, the lower surface opening of the shell body, openend passes through an end cap seal, inner housing Inside sets lamp body component, and the upper surface of inner housing is transparent glass layer, and lamp body component accesses municipal power supply by a power line, Power line part is reserved in shell body in the shape of a spiral, and through the end cap of bottom, the upper surface of shell body is provided with one for its bottom Ejection chamber, the top end face of inner housing is just provided with corresponding ejection part to ejection chamber, and a sealing is provided with the ejection chamber Layer, the gap of sealant middle setting one, gap diameter is equal to the diameter of sealant, and gap both ends open end is provided with resilient protection Layer, whole sealant is made of waterproof elastic rubber material, and the lower surface of inner housing is provided with elastic parts.

Preferably, the ejection part lateral surface is provided with a circle draw-in groove, ejection part stretches out in shell body upper surface, sealing The elastic protective layer of layer is buckled into draw-in groove.

Preferably, the outer ring of the sealant is provided with connection ring, the connection ring part is embedded in ejection cavity wall And be fixedly connected with ejection chamber.

Preferably, the lower surface of the sealant is tapetum.

Preferably, the elastic parts uses spring, inner housing outer sheath is equipped with more than one group of sealing ring, ejection part Upper surface dimpling is in the upper surface of shell body.

The beneficial effects of the utility model are：Underground lamp of the present utility model can be retracted into shell body when stressed, When being retracted into sealant lower end and upspringing again, the transparent glass layer of its inner housing upper surface is contacted with sealant bottom surface, is effectively gone Except the dust of transparent glass layer upper end, while setting elastic parts can effectively solve the problem that the problem that the long-term stress of underground lamp is damaged.

Brief description of the drawings

Fig. 1 is overall structure diagram of the present utility model；

Fig. 2 is the structural representation of sealant in the utility model；

Fig. 3 is the partial schematic diagram of ejection part in the utility model.

Coding in figure is respectively：1 is shell body, and 2 is inner housing, and 3 is ejection part, and 4 is sealant, and 5 is sealing ring, 6 It is power line, 7 is end cap, and 8 is spring, and 9 is elastic protective layer, and 11 is connection ring, and 12 is gap, and 13 is draw-in groove.

Specific embodiment

As shown in figure 1, the flexible underground lamps of this LED, including a shell body 1 and the inner housing that is set in inside shell body 1 2, the lower surface opening of the shell body 1, openend is sealed by an end cap 7, and the inside of inner housing 2 sets lamp body component, inner casing The upper surface of body 2 is transparent glass layer, and lamp body component accesses municipal power supply by a power line 6, and the part of power line 6 is in the shape of a spiral Reserve in shell body 2, its bottom passes through the end cap 7 of bottom, the upper surface of shell body 1 is provided with an ejection chamber, inner housing 2 Top end face is just provided with corresponding ejection part 3 to ejection chamber, and a sealant 4 is provided with the ejection chamber；

The gap 12 of 4 middle setting of sealant one, the diameter of gap 12 is equal to the diameter of sealant 4, the both ends open end of gap 12 Elastic protective layer 9 is provided with, whole sealant 4 is made of waterproof elastic rubber material, and the lower surface of inner housing 2 is provided with Elastic parts；

When ejection part stress, whole ejection part drops to the lower end of sealant, and sealant is one in indeformable state Individual full circle, centre is used for through the gap of ejection part for one, as shown in Fig. 2 therefore whole inner housing is by spring During ejection, its ejection part can stretch out in the outside of shell body by gap, but when ejection part upper end transparent glass layer with When sealant top surface is contacted, the part dust on transparent glass layer effectively can be removed by contact force, play the mesh of dedusting , it is ensured that the cleaning of transparent glass layer upper surface.

As shown in figure 3, the lateral surface of ejection part 3 is provided with a circle draw-in groove 13, ejection part 3 stretches out in the upper surface of shell body 1, close The elastic protective layer 9 of sealing 4 is buckled into draw-in groove 13, when ejection part stretches out in sealant upper end, the elasticity guarantor at gap two ends Sheath is buckled into corresponding draw-in groove, and the bottom surface of draw-in groove is preferably circular arc, is so more beneficial for skidding off and buckles into.

As shown in Fig. 2 the outer ring of sealant 4 is provided with connection ring 11, the connection ring 11 is partially submerged into ejection chamber Wall is simultaneously fixedly connected with ejection chamber, and the lower surface of sealant 4 is tapetum, because whole sealant uses elastic rubber material system Into, therefore contractile motion can be effectively carried out, arbitrarily deformed, when the transparent glass layer of ejection part upper end seals against the bottom of layer Portion's tapetum contact, the dust of transparent glass layer top surface is preferably removed by tapetum, it is ensured that light emission rate.

As shown in figure 1, elastic parts uses spring 8, the outer sheath of inner housing 3 is equipped with more than one group of sealing ring 5, ejection part In the upper surface of shell body 1, when whole ejection part stress, spring is pressurized 3 upper surface dimplings, and whole inner housing declines, dispersion Extruding force, while in order to ensure sealing, spy sets more than one group of sealing ring between inner housing and shell body, increases sealing Property.
