Description

A kind of rail mounted mechanism that is clamped and connected

The utility model relates to a kind of connection positioner, particularly a kind of rail mounted mechanism that is clamped and connected.In some public places, for example cinema, floor and open-air theater often will utilize that light throws light on, polishing, therefore, just require the direction of illumination of light, and angle and even distance can be adjusted or conversion by actual needs.This adjustment or conversion then require lamp holder to rotate, and can also move along default track.Sometimes in addition require lamp holder can be in the space multi-faceted the adjustment, but existing track lamp decoration mechanism can not reach above-mentioned requirements preferably, the structure of existing track lamp decoration mechanism as shown in Figure 1, it has a slide body 1A and a lamp decoration head 11A who is arranged on slide body 1A bottom, and lamp decoration head 11A can turn an angle along  shape frame 11B; Slide body 1A top has one to fasten projection 21A, fastening projection 21A card is placed in the slideway 111 of slide rail 11, fasten projection 21 by fastening spanner 2A control, promptly, so just can realize the delocalization assembling of lamp decoration head in track 111 by fastening the purpose that screws or unclamp pack into fastening projection or location fastening projection of spanner.

The existing problem of above-mentioned connection detent mechanism is:

The the 1st:, but can not longitudinally promptly regulate with respect to the above-below direction of light fixture decorations head because a light fixture decorations 11A can only carry out the delocalization assembling along the length direction of slide rail, like this, just do not satisfy the adjustment of illuminator level and scope yet, cause the scope of application to be restricted, result of use is not good enough.

The the 2nd: if the space, place is bigger, when promptly track is higher, when light fixture damages the back maintenance or very inconvenient when changing the outfit bulb.Also dangerous, especially need special-purpose ladder.

The 3rd: the structure heaviness, the special use of no cable installs conduit, makes cable be the messy state that exposes.

The 4th: can only carry out a certain delocalization assembling along the slide rail length direction, and can not make things convenient for slippage along total length, adjustment is required great effort time-consuming.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provide a kind of both can locating along the track length direction adjustment easily and flexibly of extension rod that be provided with, can vertically reach again horizontal multi-faceted adjusting and be provided with lead clamping conduit, the rail mounted of being convenient to the keep in repair mechanism that is clamped and connected.

The purpose of this utility model is to realize by following technical scheme

Length direction two symmetrical outside at track are provided with the indent draw-in groove that fastens with the V-arrangement card article, the lead shop is embedded in the U-shaped card article, clamp assemblies is to be made of two contact pin that turn to that are the axle sleeve that right-angled intersection places up and down and are connected diaxon cover axle head symmetry side, on the axle sleeve on top, be connected with the holding piece of two symmetries and epirelief, the upper end guide-joining plate of two holding pieces then with the clamping contact mutually of the lead of U-shaped card article, clamp assemblies can be provided with a group or more, light fixture is being connected with extension rod between separately the clamp assemblies in twos, so that can be installed in bottom the axle sleeve place, bottom of one group clamp assemblies.

Therefore: remarkable result of the present utility model is:

The 1st: the slip clamp structure of clamp assemblies and track not only can make light fixture carry out the position adjustment along track length direction, and can make connection light fixture thereon can change the pendulum certain angle by the rotating shaft cover of assembly bottom, both made things convenient for operation, the turning to as required of each orientation that has reached light again adjusted requirement to light.

The 2nd: but because of the lead inlay card in the U-shaped card article, so made things convenient for on-the-spot installation shop line, can make on-the-spot safer cleaner and tidier.

The 3rd: adding of extension rod can make lamp holder position or to regulate on vertical differing heights in space, to enlarge the scope of application of light fixture, simultaneously, cap part can be left behind when need keep in repair or when changing the outfit bulb easily, need not the patent ladder, maintenance also need not to ascend a height.
