Abstract
The utility model discloses a rotation type safety plug belongs to electrician's articles for use. One side of an insulating base of the electric plug is provided with a cylinder, a round head with an elastic pin on the cylinder protrudes out of the cylinder, and each pin is provided with a wire which is connected with the elastic pin in the insulating base and the cylinder. The cylinder is externally provided with a rotary sleeve which can rotate on the cylinder, the inner surface of the rotary sleeve is provided with metal rings corresponding to the elastic pins, and the outgoing lines of the rotary sleeve are respectively provided with a lead connected with each metal ring. The rotary sleeve at the outlet end of the rotary safety electric plug can rotate so as to prevent the outlet wire from being twisted into a ball to influence the use. The lead wire is provided with a zero line to ensure the use safety.
Description
1, technical field: the utility model belongs to electrician's articles for use, especially a kind of plug.
2, background technology: plug and socket use very general, and be commonly used to a kind of interim illuminating lamp in the motor vehicle repair maintenance work.The repairman is inserted in energized on the socket to plug, the time and on engine illumination work, the time and climb to illumination operation below the chassis.Illuminating lamp frequently moves, and lead is often twisted into the twisted shape pimple, makes troubles to the user of service.This situation also has same problem in the use of electric iron, electric hair cutter, electric tool etc.
3, summary of the invention: the purpose of this utility model is a kind of rotary safe plug of design, and this plug can rotate on socket with lead, and lead can not produce the fried dough twist pimple.Its technical scheme is: the insulator foot of plug simultaneously has a cylinder, another side is fixed with pin, have on the cylinder of cylinder and the radial hole of pin with quantity, each aperture all staggers mutually in the short transverse and the diametric(al) of cylinder, in each aperture outside the outstanding cylinder of the rounded nose of flexible pin, each pin all has lead to be connected a spring pivot by in insulator foot and the cylinder.Cylinder has a rotary sleeve outward, and being threaded of thread cap and cylinder upper end arranged in the rotary sleeve, and thread cap is rotated the little fin delineation position of cover cylindrical hole inner surface, between rotary sleeve and thread cap the free gap is arranged.On the thread cap end face circumference kick is arranged, the cylindrical hole end face and the kick correspondence position of rotary sleeve have pit.With each spring pivot height opposite position a becket is arranged in the rotary sleeve cylindrical hole, the lead-out wire 7 of rotary sleeve rear end has a lead to be connected with each becket respectively.
The rotary sleeve of rotary safe plug leading-out terminal can rotate, thereby prevents that lead-out wire from twisting into a Children's Film Studio of China and ringing use.Having earth connection in the lead-out wire has guaranteed safe in utilization.
4, description of drawings: Fig. 1 is the structural representation of rotary safe plug.
5, concrete real-time mode: as shown in Figure 1, insulator foot 2 one sides of plug have a cylinder 3, another side is fixed with three pins 1, have on the cylinder of cylinder and the radial hole of pin with quantity, each aperture all staggers mutually in the short transverse and the diametric(al) of cylinder, connects to make things convenient for circuit.In each aperture outside the outstanding cylinder of the rounded nose of flexible pin 4, each pin all has lead to be connected with a spring pivot by in insulator foot and the cylinder.There is a rotary sleeve 5 the cylinder outside, there is thread cap 8 to be connected in the rotary sleeve with the screw thread 10 of cylinder upper end, and the little fin circle 11 that thread cap is rotated on the cover cylindrical hole inner surface is stuck in the cylindrical hole, and the free gap is arranged between rotary sleeve and thread cap, and rotary sleeve and thread cap can be relatively rotated.On the thread cap end face circumference kick 6 is arranged, rotary sleeve has pit 9 at cylindrical hole end face and kick correspondence position.Press rotary sleeve pit is cooperated with kick, make rotary sleeve and thread cap be bonded into one, the cylindrical thread 10 of rotary sleeve from the plug base can be taken off or tighten.There is a becket 12 to be electrically connected with each spring pivot 4 height opposite position in the rotary sleeve cylindrical hole, has a lead to be connected in the lead-out wire 7 of rotary sleeve rear end respectively with each becket with spring pivot.So just the electric current in the supply socket is drawn from plug, simultaneously, plug can also rotate.
Claims (3)
1, the rotary safe plug is made up of base, pin and lead-out wire, it is characterized in that: the insulator foot of plug (2) one side has a cylinder (3), another side is fixed with pin (1), have on the cylinder of cylinder and the radial hole of pin, outside the outstanding cylinder of the rounded nose of the flexible pin of each aperture (4) with quantity; Each pin all has lead to be connected a spring pivot by in insulator foot and the cylinder; There is a rotary sleeve (5) the cylinder outside, with each spring pivot height opposite position a becket (12) is arranged on the rotary sleeve cylindrical hole inner surface, and the lead-out wire on the rotary sleeve (7) has a lead to be connected with each becket respectively.
2, rotary safe plug as claimed in claim 1 is characterized in that: each radial hole that spring pivot (4) is housed on the cylinder all staggers mutually in the short transverse and the diametric(al) of cylinder.
