Abstract
The utility model discloses a labyrinth tunnel air exchange plug for a vehicle lamp. The air exchange plug solves the problem that the prior air exchange structure of the vehicle lamp has a poor radiating effect, and has the advantages of simple structure and convenient use. Moreover, the air exchange plug can effectively guarantee hot air exchange inside the lamp and improve the radiating effect. The structure of the utility model is as follows: the air exchange plug comprises an airway duct, a tunnel plug and a tunnel cap; the tunnel plug is sleeved at the end part of the airway duct; the tunnel cap is installed on the tunnel plug; the airway duct is a conical tube, and the inner wall of the airway duct takes the shape of an inverted cone; the tunnel plug takes the shape of a round tube, and a plurality of ring-shaped grooves are formed on the outer wall of the tunnel plug, and the entire outer wall is divided into a plurality of ring-shaped lug bosses; and the tunnel cap is in the shape of a bottle lid, and a plurality of convex ribs are arranged radially at the bottom part of the tunnel cap, and the convex ribs are matched with the tunnel cap.
Description
Technical field
The utility model has related 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, and relates 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 rig that semi-enclosed automobile lamp must adopt, and especially adopts the light fixture of filament lamp or halogen tungsten light source, can not allow cold and hot air inerchange 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 deflation hole down, influences the exchange of hot air in the lamp, and radiating effect is not good.
The utility model content
The purpose of this utility model is exactly in order to solve the existing not good problem of car light air-exchanging structure radiating effect, provide a kind of have simple in structure, easy to use, can effectively guarantee hot air exchange in the lamp, the car lamp maze tunnel air exchanging plug of advantages such as raising radiating effect.
For achieving the above object, the utility model 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 the multilayer 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 offset 30 degree of ground floor groove; The position of also arranging 6 semicircle axial notches arrangements on the shellring shape boss is than 30 degree of the offset on the second layer boss; By that analogy, offset 30 degree of the more preceding one deck semi-circular recesses of axial semi-circular recesses on each layer annular boss.
Described tunnel plug is the EPDM rubber.
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; Inner end surface is on same disc.
The pneumatic duct that car lamp maze tunnel air exchanging plug of the present utility model 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 edge on the lamp housing, can make air inerchange 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 outside face drop down also, more possibility has not entered in the lamp.
The beneficial effects of the utility model are: simple in structure, easy for installation, effectively waterproof, can make the structure of carrying out interchange of heat in the lamp swimmingly again.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
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 offset 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 offset 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 22 offsets of the axial semi-circular recesses on the upper strata boss 23,30 degree.Tunnel plug 2 is EPDM rubbers.
