[detailed description of the invention]
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar improvement when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the vibration absorption lamp 100 of an embodiment comprises housing 10, light source 20, anchor ear 30, bearing 40, bearing fixed head 50, base plate 60, gripper shoe 70 and adjusting ring 80.
Housing 10 is roughly cylindrical shape.Light source 20 is roughly elongated, and it comprises the cylindrical anode seat 21 and cathode block 23 that are positioned at two ends.In the present embodiment, light source 20 is powerful xenon lamp.
See also Fig. 4, the strut 31 that anchor ear 30 comprises strip and the hoop arm 33 of two semicirculars in shape be connected with strut 31 top.The columniform anode seat 21 of light source 20 is inserted between two hoop arms 33, then anode seat 21 and two hoop arms 33 is fixed together by screw (not shown).
See also Fig. 5, the sleeve 43 that bearing 40 comprises rectangular sole 41 and is located in the middle part of sole 41.Both sides sole 41 being positioned at sleeve 43 respectively offer the through hole 411 of a strip.The bearing of trend of through hole 411 and the axes normal of light source 20.Sleeve 43 offers installing hole 431 vertically.The strut 31 of anchor ear 30 can insert in installing hole 431, and is fixed on sleeve 43 by three the screw (not shown) being positioned at sleeve 43 side.
Please again consult Fig. 2, between bearing 40 and bearing fixed head 50, be also provided with a cushion blocking 45.Cushion blocking 45 is made up of silica gel or other flexible materials, its shape roughly the same with sole 41 (see Fig. 8).On cushion blocking 45, the position of corresponding two through holes 411 offers two via holes 451.
Please refer to Fig. 6 and Fig. 7, bearing fixed head 50 is roughly a square block, and its top offers two screwed holes 51.Two bolts 53 (see Fig. 1), through after the via hole 451 on the through hole 411 of sole 41 and cushion blocking 45, are locked in these two screwed holes 51.Bearing fixed head 50 is fixed on the diapire of housing 10, such as, be adhered on diapire by heat-proof silica gel.Thus, the anode seat 21 of light source 20 is relative with housing 10 fixing.
Because most of mass concentration of light source 20 is in anode seat 21, therefore anchor ear 30, bearing 40 and bearing fixed head 50 cooperatively interact and can carry out good support by antianode seat 21.When vibration occurs vibration absorption lamp 100, cushion blocking 45 can cushion the vibration in Y direction shown in Fig. 2, and two bolts 53 can do moving back and forth in Z-direction at the through hole 411 of strip, therefore, it is possible to the vibration in buffering Z-direction.
Refer to Fig. 2, base plate 60 is bolted on the diapire of housing 10.Gripper shoe 70 is fixed at one end of base plate 60 and extends vertically upward.Both sides, gripper shoe 70 top are also respectively provided with a cantilever 71.The top of cantilever 71 is fixed on the roof of housing 10.The angle formed between two cantilevers 71 is roughly 120 degree.Two cantilevers 71 can ensure the stability at gripper shoe 70 top.Be appreciated that the quantity of cantilever 71 also can for more.Cantilever 71 also can omit.
Adjusting ring 80 is located at the top of gripper shoe 70.Adjusting ring 80 is roughly annular.The cylindrical cathode block 23 of light source 20 can insert in adjusting ring 80, and is closely cooperated by bolt 81 and adjusting ring 80.When vibration occurs vibration absorption lamp 100, cathode block 23 slightly can rock front and back in adjusting ring 80, therefore, it is possible to the vibration in buffering X-direction.
Above-mentioned vibration absorption lamp 100 comprises the cushion blocking 45 be located between bearing 40 and bearing fixed head 50, therefore forms elasticity between light source 20 with housing 10 and is connected.This structure has good damping to the vibration transmitted by housing 10, effectively can reduce housing 10 and vibrate impact on light source 20.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
