The specific embodiment
As shown in Figure 1, 2, it is the utility model first embodiment, and described lamp holder comprises socket 1 and drain pan 2, and this socket 1 and drain pan 2 be for detachable is connected, and the junction is provided with retainer plate 3.Wherein:
Described socket 1 is small-bore screw type, and bottom is one-body molded that a collar flange 11 arranged for it, and these flange 11 inwalls are provided with L shaped draw-in groove 12, and flange 11 outer walls are provided with the groove 13 that axially runs through.
Described drain pan 2 tops are provided with a boss 21 at least, these boss 21 sidewalls are provided with the fixture block 22 that can engage with L shaped draw-in groove 12 rotations of socket 1, and these boss 21 belows also are provided with one second boss 23, and the sidewall of this second boss 23 is provided with can the draw-in groove 24 relative with the groove 13 of socket 1.
Described retainer plate 3 tops are provided with flange 11 tops that inward flange 31 can be butted on above-mentioned socket 1, and these retainer plate 3 inwalls are provided with card grain 32 and can engage with the draw-in groove 24 of drain pan 2.
During assembling, earlier socket 1 is placed on the boss 21 of drain pan 2 with its flange 11, rotates this socket 1 again, make described L shaped draw-in groove 12 engage with projection 22; Then retainer plate 3 is placed in socket 1, makes its inward flange 31 and the flange 11 of socket 1 lean, the card grain 32 of together seasonal its inwall passes the groove 13 of socket 1 and is stuck in the draw-in groove 24 of drain pan 2, and chucking is fixing.
The design of said structure, make lamp holder when dismounting, the circle 3 that must be fixed is earlier vertically pulled out, again socket 1 rotation just can be finished, that is to say that its dismounting must can be finished in two steps through both direction, thereby has avoided when light fixture uses lamp holder being removed, so promptly increased safety in utilization, made it meet safety standard.
Moreover, because described socket 1 is to be installed on just now on the drain pan 2 through rotation, thus in it electrical connecting element (not shown) with drain pan 2 on electrical connecting element untrue phenomenon may appear being connected when being electrically connected.For this reason, present embodiment is made as the structure that an end is fixed an end perk with the electric-conductor on the drain pan 2 27, thereby make this electric-conductor have elasticity, like this after described socket 1 is installed, this electric-conductor 27 promptly can under the effect of elastic force with socket 1 on electrical connecting element closely contact, order more firm be electrically connected.
Shown in Fig. 3,4, it is the utility model second embodiment for another example, and the described lamp holder of this embodiment also comprises socket 1 and the drain pan 2 that detachable connects, and is provided with retainer plate 3 in the junction.The described socket 1 of present embodiment is the heavy caliber screw type, and other structure of socket 1 is identical with first embodiment with the structure of drain pan 2 and retainer plate 3.The explanation of present embodiment institute desire be can change the specification and the shape of socket very easily by this structure, and the structure of drain pan and retainer plate to be all constant, so promptly reaches the purpose of conveniently using and reducing production costs.
Shown in Fig. 5,6, it is the utility model the 3rd embodiment, the described lamp holder of present embodiment comprise socket 1 ' and drain pan 2 ', and this socket 1 ' with drain pan 2 ' for detachable is connected, and the junction be provided with retainer plate 3 '.Wherein:
Described socket 1 ' bottom outer wall be provided with a convex edge 14 ', this socket 1 bottom also split be provided with a collar flange 11 ', this flange 11 ' top be provided with interior convex edge 111 to convex ' with above-mentioned convex edge 14 ' against, flange 11 ' inwall then be provided with internal thread 112 '.
Described drain pan 2 ' top be provided with at least a boss 21 ', this boss 21 ' sidewall be provided with can with above-mentioned flange 11 ' internal thread 112 ' screw external screw thread 25 ', in addition this drain pan 2 ' boss 21 ' outside also be provided with draw-in groove 24 '.
Described retainer plate 3 ' top be provided with the above-mentioned flange 11 of inward flange 31 ' can be butted on ' the top, this retainer plate 3 ' bottom be provided with grab 33 ' can with drain pan 2 ' draw-in groove 24 ' engage.
In addition, for preventing socket 1 ' arbitrarily rotation, can this socket 1 ' the bottom be provided with a location groove 15 ', simultaneously drain pan 2 ' boss 21 ' above be provided with the locating convex block 26 of this detent 15 ' cooperate '.
During assembling, earlier with socket 1 ' with detent 15 ' the alignings drain pan 2 of its bottom ' locating convex block 26 ', and both engage mutually, to prevent socket 1 ' rotate arbitrarily; Again with collar flange 11 ' be placed in socket 1 ', and be tightened in drain pan 2 ' boss 21 ' on, thereby with socket 1 ' fixing; Then with retainer plate 3 ' be placed in socket 1 ', make its inward flange 31 ' with flange 11 ' the top lean, with season grab 33 on it ' be stuck in drain pan 2 ' draw-in groove 24 ' in, thereby chucking is fixing.
This structure makes lamp holder when dismounting, needs equally just can finish in two steps through both direction, thereby can avoid when light fixture uses lamp holder being removed, and then increase safety in utilization, makes it meet safety standard.
