The specific embodiment
With reference to the accompanying drawings the preferred embodiments of the present invention are described in detail.With reference to Fig. 1 and 2, the waterproof sealing light fixture comprises lower cover (also claiming lamp body) 1, loam cake 2 and light source 6.Lower cover 1 has the cavity that light source 6 is installed.Loam cake 2 is hinged on the upside of lower cover 1 through bearing pin 3.Loam cake 2 side periphery within it has seal groove 4.Seal groove 4 is embedded with transiens sealing ring 5.Certainly, the invention is not restricted to this, seal groove 4 also can be arranged on the lower cover 1.Uncapping and closing when covering, loam cake 2 can be around bearing pin 3 rotations.In addition, be provided with clip connection device between loam cake 2 and the lower cover 1 to realize dismounting between the two and to connect.
As shown in Figure 3, the transiens sealing ring 5 of the present embodiment frame shape that is square.Certainly, the invention is not restricted to this, for example transiens sealing ring 5 also can be rounded.This transiens sealing ring 5 is made up of first horizontal stripe 52, second horizontal stripe 53, the 3rd horizontal stripe 54 and the 4th horizontal stripe 55.Here, first horizontal stripe, 52 to the four horizontal stripes 55 are more near the rotary middle spindle (being bearing pin 3) of loam cake 2.The thickness d of transiens sealing ring 5 increases towards the direction away from bearing pin 3 gradually.That is to say, along among Fig. 3 away from the direction O of bearing pin 3, the thickness of second horizontal stripe 53, the 3rd horizontal stripe 54 and the 4th horizontal stripe 55 is linear mode and increases.Certainly, the invention is not restricted to this, also can suppose in first horizontal stripe 52, second horizontal stripe 53, the 3rd horizontal stripe 54 and the 4th horizontal stripe 55 other any one more near bearing pin 3, its principle is identical.
The variation of the thickness d of transiens sealing ring 5 of the present invention is described below in conjunction with accompanying drawing 4.As shown in Figure 4, the section 100 of a kind of transiens sealing ring 5 that the present invention adopted is trapezoidal.Need to prove that this figure only is used to explain the variation of transiens sealing ring 5 thickness d, it does not represent the true form of transiens sealing ring 5, and in fact, transiens sealing ring 5 is provided with structures such as the convexity that is used to locate or groove.The thickness d of this transiens sealing ring 5 is towards increasing away from the direction O of bearing pin 3 is linear.And the width of the thickness d of transiens sealing ring 5 and bottom surface 300 is linear in proportion to be increased.That is to say that the thickness d 1 of the closer locations among Fig. 4 is with linear than the thickness d 2 of distant positions.In addition, the end face 200 of transiens sealing ring 5 is that 3 degree are to 7 degree with the angle of bottom surface 300.In more detail, the height d1 of the rear end of this transiens sealing ring one end of bearing pin 3 (promptly near) promptly has angle between end face 200 and the bottom surface 300 less than the height d2 of front end (promptly near locking-up end), the low configuration structure in high back before forming.Like this, with light fixture loam cake 2 and lower cover 1 when sealed, transiens sealing ring rear end contacts pressurized with loam cake 2 with lower cover 1 earlier; Along with loam cake 2 continues to press down, the front end pressurized of transiens sealing ring, at this moment; The transiens sealing ring is under the extruding of covers; The deformation quantity that produces to both sides after its deformation is identical, promptly overflows whole seal groove 4, thereby reaches the integral sealing uniformity.Preferably, transiens sealing ring 5 materials in the present embodiment are selected silicon rubber for use, but its oil resistant is dirty and anti-aging, has temperature tolerance and good springiness, can effectively improve sealing.
With reference to Fig. 5, it has shown another transiens sealing ring that waterproof sealing light fixture of the present invention is adopted; Fig. 6 is the enlarged diagram at A place among Fig. 5; Fig. 7 is the enlarged diagram at B place among Fig. 5.A place among Fig. 5 leans on the rotary middle spindle of loam cake 2 nearer, and the B place is far away from the rotary middle spindle of loam cake 2.As can be seen from the figure, the thickness d of this transiens sealing ring 5 is linear increases.With reference to Fig. 6, the thickness of transiens sealing ring 5 is d3 at the A place.On the other hand, with reference to Fig. 7, and the thickness of transiens sealing ring 5 is d4 at the B place.In one embodiment of the invention, the size of d3 is 25mm, and the size of d4 is 35mm.In addition, in order to seal, to locate exactly sealing ring better and closing lid like a cork, this transiens sealing ring 5 has U-lag 51 in the side towards lower cover 1.Lower cover 1 is provided with the convexity corresponding with U-lag 11.Closing under the state of lid, protruding 11 just are pressed in the U-lag 51.Need to prove that close the required pressure of lid in order to alleviate, the degree of depth of U-lag 51 increases with it along with the increase of the thickness d of transiens sealing ring 5 in proportion, like Fig. 6 and shown in Figure 7.Like this, do not need special staff, the strength size all can be closed lid easily.
As stated, close when covering at light fixture, it is evenly reasonable that the transiens sealing ring 5 that thickness increases gradually can make the light fixture that connects through bearing pin 3 close Gai Shihe lid power, and decrement is consistent at the diverse location place, improves the waterproof sealing reliability of light fixture, simplifies the process of lid of closing.In addition, the present invention is simple and practical, is convenient to promote the use of.
Although this paper has described many embodiment, it will be understood by those of skill in the art that, can under the situation that does not break away from the spirit that is defined by the following claims and scope thereof, make other modification or change.
