Description
Technical field
The present invention relates to the structure that the inside and outside cold and hot air of a kind of made lamp that is applicable to semi-enclosed automobile lamp freely exchanges, related in particular to a kind of car lamp maze tunnel air exchanging plug.
Background technology
The car light air-exchanging structure is a kind of heat-exchange device that semi-enclosed automobile lamp must adopt, and especially adopts the light fixture of incandescent lamp or halogen tungsten light source, can not allow cold and hot air exchange in the lamp if can not dispel the heat, and will greatly influence the service life of light fixture.
At present the air interchanger that adopts on the light fixture mostly is " U " shape sebific duct and square sebific duct, and the mouth of pipe is intake in lamp avoiding down during assembling.Though this structure has certain radiating effect, it can not be arranged on the upper limb and the lower edge of lamp housing, add that again this class sebific duct has certain-length, the mouth of pipe certainly will reduce the height of steam vent down, influences the exchange of hot-air in the lamp, and radiating effect is not good.
Summary of the invention
Purpose of the present invention is exactly in order to solve the existing not good problem of car light air-exchanging structure radiating effect, provides a kind of and has simple in structurely, easy to use, can effectively guarantee hot-air exchange in the lamp, improves the car lamp maze tunnel air exchanging plug of advantage such as radiating effect.
For achieving the above object, the present invention adopts following technical scheme:
A kind of car lamp maze tunnel air exchanging plug, it is made up of pneumatic duct, tunnel plug and tunnel cap, and the tunnel plug sleeve is contained in the pneumatic duct end, and the tunnel cap is installed in the tunnel beyond the Great Wall; Wherein pneumatic duct is a conical tube, and its inwall is a back taper; The tunnel plug is a tubular type, and its outer wall is provided with a plurality of annular ditch grooves, and whole outer wall is divided into a plurality of annular boss; The tunnel cap is a bottle cap shape, and cap bottom in tunnel is the convex tendon of a plurality of radial arrangement, and convex tendon matches with the tunnel cap; The described tunnel annular ditch groove of wall beyond the Great Wall is equally spaced semicircle ring-type groove; Each annular ditch groove is divided into four layers of annular boss to the outer wall of tunnel plug; On the ground floor annular boss of described tunnel plug, along its circumference, evenly distributed 6 axial semi-circular recesses; Arrange 6 axial semi-circular recesses on second layer annular boss too, the position of its arrangement is than position skew 30 degree of ground floor groove; The position of also arranging 6 semicircle axial notches arrangements on the shellring shape boss is than the skew of the position on the second layer boss 30 degree; By that analogy, the position of the more preceding one deck semi-circular recesses of axial semi-circular recesses on each layer annular boss skew 30 degree; The convex tendon of cap bottom, described tunnel radial arrangement is 6 semicircle convex tendons, and the inwall of the outer face of convex tendon and tunnel cap is tangent, and inner face is on same disc.
Described tunnel plug is the EPDM rubber.
The pneumatic duct that car lamp maze tunnel air exchanging plug of the present invention at first respectively is provided with a level at the upper limb and the lower edge of lamp housing.The inwall of pneumatic duct, the collar extension size is big, and the internal orifice size is little, can prevent effectively that rainwater from flowing in the lamp.
The tunnel plug is filled in the tunnel cap, the tunnel groove in length and breadth on the wall has beyond the Great Wall just formed the labyrinth type tunnel, fill in the above-mentioned tunnel cap that installs the tunnel plug on the pneumatic duct together again, because the arc surface of the radial semicircle convex tendon of tunnel cap bottom is against the outer face of pneumatic duct, the maze tunnel in the tunnel cap just has been communicated with pneumatic duct.Be in the maze tunnel of lower limb on the lamp housing, can make air exchange in the lamp very effectively, simultaneously, because the cause of tunnel plug, enlarged the outside dimension of pneumatic duct, can not enter maze tunnel even the rainy current of lamp housing outer surface drop down also, more possibility has not entered in the lamp.
The invention has the beneficial effects as follows: simple in structure, easy for installation, effectively waterproof, can make the structure of carrying out heat exchange in the lamp swimmingly again.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, it is made up of car lamp maze tunnel air exchanging plug pneumatic duct 1, tunnel plug 2 and tunnel cap 3, and wherein pneumatic duct 1 is a conical tube, and its inwall is a back taper; As shown in Figure 2.
Among Fig. 3, Fig. 4, Fig. 5, tunnel plug 2 is that an external diameter is 18mm, and internal diameter is 10mm, the pipe of long 12mm.The outer wall of pipe is being arranged 3 semicircle ring-type grooves 21 of 3mm equidistantly; These three annular ditch grooves 21 are divided into 4 annular boss 23 to the outer wall of tunnel plug 2.On ground floor annular boss 23, along its circumference, evenly distributed 6 semi-circular recesses 22 that axial radii is 1.2mm; Arrange 6 axial semi-circular recesses 22 on second layer annular boss 23 too, the position of its arrangement is than position skew 30 degree of ground floor groove 22.Also arranging position that 6 semicircle axial notches 22 arrange on the shellring shape boss 23 than 23 position skew 30 degree on the second layer boss.By that analogy, the axial semi-circular recesses 22 on the 4th layer of annular boss 23 is than the skew of axial semi-circular recesses 22 positions on the upper strata boss 23 30 degree.Tunnel plug 2 is EPDM rubbers.
