Directly influence the service life of projecting lamp.Existing projecting lamp includes shell, and the peace sealed by light-transmitting plate is provided in shell
It behave affectedly, circuit board is installed in installation cavity, and power supply line passes through the threading hole being arranged on shell and connects circuit board, existing projection
The threading hole of lamp does not have sealing structure, and water may be entered in installation cavity along power supply line by threading hole, to cause circuit board
Short circuit.
Utility model content
To solve the disadvantage that the prior art and deficiency, a kind of waterproof projection lamp fitting is provided, so that realizing prevents rainwater from entering
Lamp interior corrodes the purpose of circuit board.
The utility model solves the problems, such as this technical solution taken are as follows:
A kind of waterproof projection lamp fitting, including shell are provided with installation cavity on the shell, are installed with electricity in the installation cavity
Road plate is provided with light source on circuit board, is covered with light-transmitting plate above the installation cavity, the installation cavity bottom is provided with threading
Hole, the threading hole include close to extraneous connecting pin and close to the encapsulating end of installation cavity, and the internal diameter at the encapsulating end is greater than
The internal diameter of connecting pin.
Further, the installation cavity periphery is provided with the inward flange for support light-transmitting plate, and the hull outside is provided with
Around the periphery sides of inward flange, encapsulating groove is provided between the inward flange and periphery sides.
Further, the width of the encapsulating groove is less than the width of inward flange, and the width of encapsulating groove is 0.8-1.5mm,
The width of inward flange is 1.5-3mm.
Further, the installation cavity bottom is provided with several bolt mounting holes, is bolted to bolt across circuit board
On mounting hole.
Further, the aluminum enclosure that the shell is integrally formed, housing bottom are provided with radiating fin.
Further, the threading hole is provided with multiple, including electric power incoming line perforation and power outlet perforation adjacent to each other.
The beneficial effects of the utility model are: a kind of waterproof projection lamp fitting of the utility model is adopted compared with prior art
It is that the threading hole that will be used to connect between circuit board and power supply line, data line is set as stairstepping, it is wider in threading hole
Plastic cement sealing can be injected in position, effectively prevents water by data line and power supply line and corrodes circuit board, while in installation cavity
An encapsulating groove is arranged in edge, and light-transmitting plate is placed on after installation cavity and injects plastic cement, is sealed against on installation cavity, makes
Rainwater can not enter inside installation cavity from the gap of light-transmitting plate and installation cavity, and effectively prevent rain erosion circuit board can
Can, improve the service life of projecting lamp.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, in which:
Fig. 1 is a kind of structure chart of waterproof projection lamp fitting of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the partial sectional view of Section A-A in Fig. 2；
Fig. 4 is the enlarged drawing in Fig. 1 at B；
Specific embodiment
Referring to figs. 1 to shown in Fig. 4, a kind of waterproof projection lamp fitting in the present embodiment, including shell 1 is provided with peace on shell 1
It behave affectedly 2, circuit board is installed in the installation cavity 2, light source is provided on circuit board, the present embodiment light source uses LED lamp bead 3,
It is environmentally protective, impact resistance, anti-Lei Liqiang.Light-transmitting plate is covered with above installation cavity 2,2 bottom of installation cavity is provided with threading hole 4, wears
String holes 4 includes close to extraneous connecting pin 5 and close to the encapsulating end 6 of installation cavity 2, and the internal diameter at encapsulating end 6 is greater than connecting pin 5
Internal diameter injects plastic cement sealing at encapsulating end 6, be flowed into rainwater can not along power supply line inside installation cavity 2, it is therefore prevented that rainwater is invaded
Lose the possibility of circuit board.2 periphery of installation cavity is provided with the inward flange 7 for support light-transmitting plate, is provided on the outside of shell 1 around interior
The periphery sides 8 of flange 7, are provided with encapsulating groove 9 between inward flange 7 and periphery sides 8, inject plastic cement sealing from encapsulating groove 9, prevent
Stop rainwater to be flowed into inside installation cavity 2 from the gap of light-transmitting plate and installation cavity 2, it is therefore prevented that rain erosion circuit board improves
Projecting lamp service life.By a large amount of it was verified that specifically, being filled when the width of encapsulating groove 9 is less than the width of inward flange 7
The width of glue groove 9 is between 0.8-1.5mm, when the width of inward flange 7 is between 1.5-3mm, injects plastic cement from encapsulating groove 9
Sealing effect afterwards is best, and 2 stable connection of light-transmitting plate and installation cavity, the service life longest of projecting lamp.At 2 bottom of installation cavity
Portion is provided with several bolt mounting holes, and across being bolted on bolt mounting holes for circuit board, convenient disassembly is conducive to maintenance,
