Description
Technical field
The utility model relates to light fixture, relates in particular to a kind of lamp connection damper.
Background technology
Lamp is as a kind of lighting apparatus, often be installed on room or the equipment, connected mode commonly used is that bulb or fluorescent tube (hereinafter to be referred as lamp) are connected on the lamp holder, lamp holder directly hangs on the wall by lead or connecting rod or on the equipment, in case be given a shock, as directly carrying out ways of connecting for lead, because rocking easily, lead the lamp rolling can be fallen, if connect by connecting rod, because connecting rod does not have elasticity, vibrations can be directly delivered on the lamp, and lamp is shaken, and so not only can cause the improper damage of lamp, simultaneously just in case pound people or other article, can cause any property loss and casualties, unfavorable safety also can be made great injury mentally to victim and household thereof simultaneously.At Chinese Granted publication number is CN201568805U, name is called in the patent documentation of " a kind of desk lamp " and discloses a kind of desk lamp, his lamp body (being equivalent to be connected with the lampshade of lamp holder) directly is connected on the lamp socket by lamp stand, the shortcoming that it has existing lamp above-mentioned to connect, promptly not shockproof, in case be given a shock, lamp shakes bad easily or splits away off from lamp body.
Summary of the invention
The utility model provides a kind of lamp with shock-absorbing function to connect and has used damper, has solved existing lamp and has been given a shock the problem that Shi Yizhen is bad or drop.
Above technical problem solves by following technical proposal: a kind of lamp connects uses damper, comprise sliding sleeve, described sliding sleeve is built-in with decoupling rod, described decoupling rod can move in described guide pin bushing, be provided with spring in the described guide pin bushing, described spring one end is connected on the described decoupling rod, the other end is connected on the described guide pin bushing, and described damper one end connects lamp holder, the other end is connected needs to install the lamp place.When lamp holder is connected with the place that needs the installation lamp by this damper, lamp holder is connected on decoupling rod and the guide pin bushing with the place that needs the peace lamp, because decoupling rod can move in guide pin bushing, when so vibrations are arranged, guide pin bushing and decoupling rod can push or extension spring, thereby change vibration energy into elastic potential energy by spring, play cushioning effect, make lamp be difficult for being fallen by shake to lamp.
As preferably, described spring housing is located on the described decoupling rod.Make spring, guide pin bushing, decoupling rod three almost coaxial line, when guide pin bushing and decoupling rod extruding or extension spring, it circumferentially is subjected to the reaction force equilibrium of spring, make the direction of motion substantially along axis direction, thereby be difficult for causing the rocking of off-axis direction of lamp because of the power that produces the off-axis direction.
Preferred as another, described spring is between described decoupling rod and described guide pin bushing.Lamp produces and departs from rocking of damper axis direction when shaking in order to overcome, and spring is provided with two at least, and is evenly distributed between decoupling rod and the guide pin bushing.Certainly under less demanding situation, for convenience's sake, also can with a spring to damping.
As preferably, on an end of described guide pin bushing, be provided with the cover link stopper, the span piece that is provided with on an end of described decoupling rod, described spring are connected between described cover link stopper and the described span piece.The connected mode of butt, spring are installed and are changed conveniently.
As preferably, the cross section of described decoupling rod is circular, and the cross section of described sliding sleeve is an annular, described span piece be an end of described decoupling rod to the formed cylinder of outer lug, the internal diameter of described cylindrical diameter and described guide pin bushing is complementary.Circular design makes decoupling rod be easy to slide in guide pin bushing.Cylindrical diameter on the decoupling rod and the internal diameter of guide pin bushing coupling makes to be difficult for generation when sliding and radially to depart from and cause radially rocking of lamp.
As preferably, described cover link stopper is the annular back-up ring, between described back-up ring and the described guide pin bushing for being threaded.Easy to assembly.
As preferably, on described guide pin bushing wall, have the strip through hole, described through hole extends axially along described guide pin bushing, is connected with fixed bar on described decoupling rod, and described fixed bar passes described through hole, and described fixed bar can slide in described through hole.Be used to limit the displacement of decoupling rod in guide pin bushing on the one hand, on the other hand, for spring require low, because, when requiring spring will reach some higher coefficient of elasticity, two kinds of selections can be arranged, one is directly with the big spring of coefficient of elasticity, make spring when not shaking in the raw, it two is with the little spring of coefficient of elasticity, spring just is not in compression or elongation state (energy storage state) when shaking, and limit spring by this structure this moment, makes it can not be in the raw.
As preferably, described decoupling rod is threaded on the described lamp holder, and described guide pin bushing is threaded on the lamp stand connector.The mode easy accessibility that is threaded makes this damper and push rod easy to connect by the lamp stand connector is set.
The utlity model has following advantage, after lamp was connected the place that needs the installation lamp by this damper, anti seismic efficiency was good, not fragile, reduced the improper damage of lamp,, be difficult for producing the security incident that drops and cause because of lamp for the user has saved expense, user's sense of security height, this use is novel with regard to three members, and is simple in structure, by changing the different spring of elastic effect, just can satisfy the damping requirement under the different environments for use, versatility is good.
