Fig. 2 is the structure explosive view of special lamp vibration damper embodiment of the present invention;
Fig. 3 is the section of structure of special lamp vibration damper embodiment of the present invention;
Fig. 4 utilizes the embodiment of special lamp vibration damper of the present invention to carry out the schematic diagram that the suspension type light fixture is installed.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, in embodiment according to special lamp vibration damper provided by the invention, comprise shock absorber spiral cover 100, profiled screw 200, as cover 300 in the rubber sleeve 210 of first buffer unit, the friction, as the rubber liner 400 and the damper shell 500 of second buffer unit, wherein profiled screw 200 and rubber sleeve 210 are one by compression molding.Concaveconvex structure joins as Fig. 3 between rubber sleeve 210 and the profiled screw 200, and several layers of boss are arranged on the profiled screw 200, and rubber sleeve on the other side 210 is relative with groove because of these boss, can guarantee to have reliable connection so between the two.Profiled screw 200 is provided with lamp installation screw thread 220, is used to connect light fixture.Carry out when light fixture is installed spacingly, be provided with on profiled screw 200 and be used to install the spacing positive stop lug boss of light fixture 250, above-mentioned installation screw thread 220 is located at positive stop lug boss 250 outsides (Fig. 3).
Profiled screw 200 is at its end face that other end that screw thread 220 is installed is arranged, and the end face that promptly stretches out shock absorber shell 500 is provided with interior hexagonal groove 230, inserts the outer-hexagonal spanner when being used to install and positions.In the same end periphery of shock absorber shell 500, be provided with shock absorber screw thread 510 be installed, be used for special lamp vibration damper of the present invention itself by with being connected of the screw-threaded engagement realization that nut is installed and mounting bracket etc.
Except the rubber sleeve 210 as first buffer unit separates profiled screw 200 and shock absorber spiral cover 100,,, profiled screw 200 other ends and shock absorber shell 500 are separated as the rubber liner 400 of second buffer unit as Fig. 3.Rubber sleeve 210 top boss 240 are suitable mutually with shock absorber spiral cover 100 mesopores, and also available vibration isolation rubber packing ring replaces, thereby slows down radial vibration.From axially; the two ends that shock absorber of the present invention connects; see to conduct vibrations it is to hinder or isolation from the conduct vibrations aspect; thereby the vibration of protection on the support that shock absorber shell 500 1 ends install to connect can or seldom can not be transmitted to the special lamp that profiled screw 200 1 ends connect, thus guarantee light fixture nothing shake or the vibration damping state under work.
The vibration that rubber sleeve 210 is used to block or decays and bring from profiled screw 200 and shock absorber shell 500.Rubber sleeve 210 is mainly up big and down small wedge structure, be used for cover 300 in the friction closely is contained in the relevant position of rubber sleeve 210, rubber liner 400 then can be packed cover 300 in the friction therebetween into, shock absorber shell 500 rubber liner 400 of then packing into, in will rubbing by rubber liner 400 cover 300 and rubber sleeve 210 and profiled screw 200 is encapsulated in and shock absorber spiral cover 100 between in the confined space that forms.
In vibration processes, vibrational energy from vibration source mainly absorbs by the distortion of rubber sleeve 210 and rubber liner 400, cover 300 can be made with sheet metal in the friction, its effect is to reduce between rubber sleeve 210 and the rubber liner 400 in the wearing and tearing of contact-making surface and pressure is evenly transmitted, and then make both homogeneous deformations, thereby reach the purpose of vibration damping, vibration isolation.
Special lamp vibration damper provided by the invention both can use separately because volume is less, also can a plurality ofly use together.Installation comprises mounting dampers and two parts of light fixture is installed.Mounting dampers is that one or more shock absorbers are installed to the position that light fixture is directly installed in original preparation.Light fixture is installed to be meant lamp installation to shock absorber provided by the invention.As shown in Figure 4, first link is, two dampers linked together by damper shell 500 and nut and gripper shoe 600 respectively, and then be fixed by bolts on the basic installation position 700, promptly finished the installation of shock absorber.Second link be, will adjust to a suitable position with the support 810 that light fixture 800 links together, and 2 profiled screws 200 of damper are penetrated in the installing hole on the support 810, and the nut of screwing on compresses, and has just finished the installation of light fixture.
Similarly, can realize that keeping away the vibration isolation of shaking with more a plurality of special lamp vibration dampers of the present invention connects.Certainly, utilize special lamp vibration damper of the present invention also can hang the article of installation such as projecting apparatus.
Above embodiment has only expressed preferred implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention; 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, all equivalents and modifications of being done in claim scope of the present invention all should belong to the covering scope of claim of the present invention.
