The specific embodiment
Shown in Fig. 1~2; In present embodiment, the syndeton of the described a kind of shadowless lamp lamp holder of the utility model comprises bend pipe 2 and connector 1; Connector 1 adopts hollow structure; Bend pipe 2 one ends extend to connector inside by connector 1 one ends, and through being distributed on the peripheral some screws 5 of connector that both are fastening, by connector 1 other end device joint 3 its inside of packing into that will conduct electricity; And the limitation locking mechanism of the device joint that conducts electricity is set, the situation that the device joint 2 that prevents to conduct electricity excessively causes electric wire to damage in connector 1 inner rotation on connector.
Concrete, connector 1 set inside step surface is installed metallic gasket 4 on step surface; Bend pipe 2 matched in clearance extend to connector inside; Its end and pad 4 lean, like this can so that conduct electricity device joint 3 with connector 1 inner gapped situation under place relatively reposefully wherein, improved the efficient of docking of the interior female joint of the device joint that conducts electricity (male joint) and balanced body; Clamping times when having reduced connector processing simultaneously improves process velocity.
Simultaneously evenly have some screwed holes in connector 1 periphery, corresponding this screwed hole evenly has screwed hole in bend pipe 2 peripheries, realizes fastening between bend pipes 2 and the connector 1 through screwing in screw 5 in the screwed hole.
The screwed hole quantity that this place is offered is at least three, can guarantee the connection reliability between connector and the bend pipe like this for three or four or the like.
Coated thread fastening agent on screw 5 also simultaneously; Can improve connection reliability, preferred thread locking agent is the agent of locking anaerobism, and shock effect is easy to produce loosening or off line because metallic screw is hit; Traditional mechanical lock solid method is all not ideal enough, and chemical locking method is effectively cheap.Join if screw is coated the laggard luggage of anaerobic adhesive, solidify the back and in thread pitch, form tough plasticity glued membrane, screw lock can not become flexible.Precoating type (B-204) anaerobic adhesive has been arranged now, be coated in advance on the screw, placed (term of validity 4 years) for use, screwed, can reach the anti-loosing effect of expection as long as screw is screwed into.
Bend pipe 2 is connected for the gap with connector 1; Can be so that screw 5 have enough spaces can adjust size, and adopt three or four screw five equilibriums to be threaded, cause the connection between bend pipe 2 and the connector 1 to produce enough big pulling force; Improved the reliability that connects; Prevented the inefficacy of bend pipe and connector and the danger that comes off, screw 5 adopts the screw of stainless steel material, has improved the persistence of outer aesthetic.
The device joint 3 that conducts electricity of in connector 1, packing into; And upload electrical equipment packing ring 6 at the device joint 3 bottom pads that conduct electricity, and make the device packing ring 6 that conducts electricity lean with pad 4, the device joint 3 that conducts electricity places in the connector 1; Can make the female joint in its butt joint balanced body carry out 360 ° of unrestricted rotations effectively; Under be lined with the device packing ring 6 that conducts electricity, make the device joint (male joint) that conducts electricity be elevated, can effectively improve the contact length of female, male joint docking site; The device packing ring 6 of preferably conducting electricity adopts the packing ring of nylon materials, and the device joint 3 that can effectively prevent to conduct electricity possibly produce that conduction be connected and the danger that takes place with bend pipe is inner.
The conduct electricity bottom of device joint 3 is provided with notch 11; Corresponding notch 11 has screwed hole on connector 1; In screwed hole, screw in stop screw 7, stop screw 7 extends to device joint 3 inside that conduct electricity through notch 11, and is positioned at device packing ring 6 tops that conduct electricity; Stop screw 7 can play position-limiting action, and the device joint that prevents to conduct electricity is owing to rotate the situation that excessively causes electric wire to damage on same direction.
The outside that is positioned at the inherent stop screw 7 of screwed hole screws in the tight screw 8 of the back of the body, and the length of stop screw is greater than the length of the tight screw of the back of the body, and stop screw 7 extends to the device joint inside that conducts electricity and plays position-limiting action, carries on the back tight screw 8 and has played fastening locking effect outside.
Peripheral ring cutting at connector 1 has two grooves 9, the packing ring 10 of in groove 9, all packing into, and preferred packing ring 10 adopts the packing ring of polytetrafluoroethylmaterial material; Utilize the character of its flexible material, make that can carry out transition with the different balance arm under special circumstances is connected, and reaches the positive engagement that the seamless nothing in junction is rocked; Also do not influence simultaneously the electric conductivity of shell, preferred packing ring 10 is an open washer, during installation; By being applied to the external force on the packing ring; Packing ring is snapped in the groove, and so mounting means makes that installation is more convenient, and installs also more reliable.
What need statement is; The above-mentioned specific embodiment only is preferred embodiment and institute's application technology principle of the utility model; In technical scope disclosed in the utility model; Any variation that the technical staff expected easily or replacement of being familiar with the present technique field all should be encompassed in the protection domain of the utility model.
