Beneficial effect is：Compared with prior art, a kind of underground lamp of the present invention is made by setting the first groove on lamp holder
The side wall or bottom wall of first groove and the end face of first through hole connect, and then set fluid sealant in the first groove, prevent water from passing through
Entered by the gap between conducting wire and first through hole inside underground lamp, avoid producing water mist phenomenon.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is a kind of structure diagram of underground lamp of the present invention.
Embodiment
As shown in Figure 1, a kind of underground lamp, including lamp holder 1, lamp body, lampshade and conducting wire 3.Lamp holder 1 and lampshade form accommodating lamp
The confined space of body.Lamp body and lampshade are not the improvement emphasis of the present embodiment, are not drawn into.
When underground lamp is opened, lamp body can give off heat so that the air expansion in confined space；When underground lamp is closed
Lamp body stops producing heat, and the air in confined space is shunk.If containing more moisture in air, the moisture meeting in air
Droplet is condensed into, produces water mist phenomenon.
Under normal conditions, conducting wire 3 is connected after passing through lamp holder 1 with lamp body, is passed through correspondingly, lamp holder 1 is provided with accommodating conducting wire 3
First through hole 2.
One sealing ring can be set in design at first through hole 2, prevent water from entering at first through hole 2 inside underground lamp.
Sealing ring can prevent the water of big stock from entering, however, sealing ring cannot prevent the entrance underground lamp of air contained water.
When underground lamp is opened and closed, air contained water can be slowly drawn into inside underground lamp.Accumulate over a long period, when underground lamp uses
After time exceedes half a year, the water content of underground lamp inner air is very high, can be condensed into droplet, produces water mist phenomenon.
To solve this problem, lamp holder 1 can be provided with the first groove 4, the side wall of the first groove 4 or bottom wall and first
The end of through hole 2 connects, and fluid sealant 5 is provided with the first groove 4, fluid sealant 5 is in block or thick, fluid sealant 5 and conducting wire 3
Outer surface fitting, the surface of the circumferential direction of fluid sealant 5 and first through hole 2 is bonded.
In other words, fluid sealant 5 is to be injected after lamp holder 1 manufactures in the first groove 4.Fluid sealant 5 is in injection the
Bulk is frozen into after in one groove 4 or cannot arbitrarily be flowed thick.
Since fluid sealant 5 can fill the first groove 4, and the gap between conducting wire 3 and first through hole 2 is blocked, can prevent sky
Gas enters inside underground lamp.
To prevent fluid sealant 5 from being overflowed at first through hole 2, lamp holder 1 is additionally provided with the first bolt 6 of connection first through hole 2,
The axis direction of first bolt 6 is provided with the second through hole that accommodating conducting wire 3 passes through.
To improve the sealing effect of the first bolt 6, first through hole 2 in step-like, first through hole 2 include the first hole portion 21,
Second hole portion 22, the connection circular conical surface 23 for connecting the first hole portion 21 and the second hole portion 22, the first hole portion 21 connect with the first bolt 6
Connect, the first cushion rubber is provided between 23 and first bolt 6 of circular conical surface.
First bolt 6 promotes the first cushion rubber, the first cushion rubber is deviated towards the direction of first through hole 2, meanwhile, make the first cushion rubber
It is in close contact, the radially-outer surface of conducting wire 3 can be sealed with circular conical surface 23.
First cushion rubber can be the extension of the plastic shell of conducting wire 3, that is, the first cushion rubber can be with the modeling of conducting wire 3
Material shell is integrally formed, but manufacture cost can increase.
To avoid fluid sealant 5 from being heated overflow, the first groove 4 is arranged at the bottom of lamp holder 1, and the first groove 4 is arranged at lamp holder 1
Inside.
Certainly, the oral area of the first groove 4 is set upward accordingly, this also facilitates lamp holder 1 to pass through pouring molding.
To reduce the heated volatilization of fluid sealant 5, lamp holder 1 is additionally provided with the lid for covering the first groove 4, and lid is provided with accommodating
The third through-hole that conducting wire 3 passes through, it is simple in structure, it is not drawn into.
When the metal inside of conducting wire 3 is made of single-wire, it is first naked to be provided with bare metal inner core for conducting wire 3
Reveal section, the first naked section is arranged inside fluid sealant 5.It can so prevent plastic skin and metal core of the air contained water through conducting wire 3
Between fine gap enter underground lamp inside.First naked section does not have big change to 3 structure of conducting wire, it is readily appreciated that, do not scheme
Show and draw.
Since the metal inside of conventional wires 3 is made of more wires, fluid sealant 5 is hardly entered between metal wire
Gap, also allow for air contained water can through the gap between metal wire enter underground lamp inside.
To avoid the generation of this case, conducting wire 3 can be made to include first segment electric wire 31, second segment electric wire 32, by first
The metal derby 33 that section electric wire 31 and second segment electric wire 32 connect, first segment electric wire 31 are connected with lamp body, and second segment electric wire 32 connects
External power supply, metal derby 33 are arranged inside fluid sealant 5.
Metal derby 33 is block entity, does not retain the gap between original metal wire, fluid sealant 5 can be with 33 nothing of metal derby
Seam fitting, has blocked air contained water to enter the path in underground lamp through the inside of conducting wire 3, ensure that the sealing of underground lamp.
To ensure that fluid sealant 5 can be bonded completely with metal derby 33, metal derby 33 and the side wall or bottom wall of the first groove 4 lead to
Cross plastic stent connection.
After conducting wire 3 is connected with lamp holder 1, just fluid sealant 5 is injected in the first groove 4, avoids metal derby 33 and
One groove 4 contacts and prevents fluid sealant 5 from being completely attached to metal derby 33, and also the attended operation to conducting wire 3 and lamp holder 1 does not produce
Influence, can meet the professional standard of electric wire connection.
The metal derby 33 of the present embodiment can also use wire connection terminal etc. be replaced, and not retain between multiple metal wires
Gap.
The above embodiments are merely illustrative of the technical solutions of the present invention and is not limited, all without departing from the present invention
Any modification of spirit and scope or equivalent substitution, it should all cover in the range of technical solution of the present invention.
