As shown in Figure 1, the present embodiment lampshade revolves the positioner that moves retractor device and water proof switch lamp socket, and wherein lampshade revolves and moves retractor device and be made of a flashlight cylinder 1, a bulb socket 2 and a lampshade 3, wherein,

Flashlight cylinder 1 front end has an external screw thread 11, and is sealed for bulb socket 2, has a large and small class hole 12,12 ' in the cylindrical shell, is positioned at big class hole 12 surperficial barrel appropriate locations, is to be provided with a key hole 13, and is provided with a back cover 14 at the end lock of cylindrical shell 1;

Bulb socket 2 is by a hollow tube, its inner wall at end is provided with internal thread 21, the front end external annulus branch rings such as select location establish offer on three projections 22 and the circumference anchor ring at external annulus three guide channels 23 that are camber line to the end and the front end of guide channel 23 card that has the form bending respectively end ditch 231;

Lampshade 3 is the printing opacity cover body that is a hollow, its front end outer wall is to be provided with an external screw thread, for a sealed lamp cover 31 and locking location one reflection shield 32 in the lump, at the hole of latter end internal face is to be to be provided with three

ring ribs

33,34,35 with suitable spacing, and so as to forming twice circular groove 341,351, for embedding a packing ring 36 and a rubber ring 37 respectively.Offer three breach 331 (as shown in Figure 4) at the first ring rib, 33 first-class branches again, and select location convexes with three prominent 342 (as shown in Figure 3) on the second ring rib, 34 end faces;

The positioner of water proof switch lamp socket system is held members such as a shell fragment 5 and an antiseepage button piece 6 and is fastened in the big class hole 12 of flashlight cylinder 1 and constitutes by a switch lamp socket 4,, wherein:

Switch lamp socket 4 front ends are that lock is established a tube face 41, and this tube face 41 is provided with a bulb 411; The other end then connects battery; The place then is provided with a depressed part 42 at pedestal ring wall end face proximal end, in these depressed part 42 centre and there is the button of a step shape to hold hole 43, making a button assembly 44 hold 43 bottoms, hole by button holds wedge and stretches out, again with a cap ring 441 location that locked, again its forward and backward side in base body ring wall bottom be have the rank wall 45 of contracting in, 45 ' and forward and backward in contract rank wall 45,45 ' root edge be to have a groove 451,451 ' respectively;

Holding elasticity 5 is to be half arc plate, and at the raised line 51 of its lamellar body guide center bending, the bottom of this raised line 51 is to form to have a chase 511, and to be outside bending have a fin 52,52 ' respectively in both sides;

Antiseepage button piece 6 ties up to centre and upwards swells a flexible keypad 61, and places the depressed part 42 of switch lamp socket 4;

The lampshade of present embodiment revolves and moves retractor device when assembling, in two circular grooves 341,351 with lampshade 3, embeds a packing ring 36 and a rubber ring 37 respectively earlier earlier, makes bulb socket 2 be inserted in after by forward direction by calibers in the lampshade 3 again; Fashionable when overlapping, the guide channel 22 that makes bulb socket 2 external annulus by end openings just in time respectively wedging at the set prominent grain 342 ' of the inwall ring rib 34 of lampshade 3, the end and the bulb socket 2 set projections 22 that make the back segment cover of bulb socket 3 stretch out lampshade 3 again just in time pass the breach 331 that lampshade 3 first ring ribs 33 are offered respectively, and card ends in circular groove 341.Then, again bulb socket 2 is locked together in the external screw thread 11 of flashlight cylinder 1 front end and combination with the set internal thread of inner wall at end.Moreover the front end of lampshade 3 is put a reflection shield 32 earlier and is relended a lamp cover 32 and relend a lamp cover 31 location that locked, and the lampshade that can form a flashlight revolves and moves retractor device.

Moreover the lampshade of above-mentioned flashlight revolves and moves retractor device, and its action situation is that details are as follows:

When making its work stretch out displacement when forward rotating lampshade 3, move, end in the ditch 231 until prominent the 342 fixed cards that only are being guided into groove 23 even the guide channel 23 that the prominent grain 342 of lampshade 3 is offered along bulb socket 2 external annulus revolves gradually, the set projection 22 of bulb socket 2 external annulus front ends is to be entered in the circular groove 341 and work card fastening position (as shown in Figure 5) by the ring rib 33 set breach 331 of lampshade 3 simultaneously; So, the bulb 21 that bulb socket 2 installed is to break away from the reflection shield 32 of lampshade 3 and place lampshade 3 inside, make the light of bulb 21 can borrow the printing opacity cover body of lampshade 3 expose to the outside, and be indirect lighting, with as: baton, mini light night or the use of caution lighting function.Otherwise when reverse rotation lampshade 3,342 cards that break away from guide channel 22 of prominent grain of this lampshade 3 end ditch 231, and retreat do turn along guide channel 23, import in reflection shield 32 (as shown in Figure 6) until bulb 21, use to do direct illumination.

During the assembling of the positioner of the water proof switch lamp socket of present embodiment, the bottom that the key groups 44 of switch lamp socket 4 is held hole 43 by button is held wedge and is stretched out earlier, will lock knot with cap ring 441 again and fix.Then, antiseepage button piece 6 is placed the depressed part 42 of switch lamp socket 4, and make the bottom of flexible keypad 61 just be coated on button assembly by on the key head 442; The switch lamp socket 4 that this assembling is finished is wedged in flashlight cylinder 1 (in the big class hole 12 again, again order hold shell fragment 5 slightly inwardly contract scratch bending deformation after, again along the rank wall 45 that contracts in switch lamp socket 4 bottoms, the groove 451 of 45 ' root edge, 451 ' wedging location, discharge again and hold shell fragment 5 reinstatements, make and hold shell fragment 5 and expand outwardly, and make the raised line 51 that holds shell fragment 5 play the groove 451 of top switch lamp socket 4 bottoms, 451 ', and both sides fin 52,52 ' compels to be against flashlight cylinder 1 inwall place respectively, encircle the anterior wall caulking groove of 15 snibs with a C again in the big class hole 12 of flashlight cylinder 1, and, can make switch lamp socket 4 obtain good positioning and fixing effect with an end face of a C type ring 15 rank end face with fixing switch lamp socket 4.Moreover, the button assembly 44 of switch lamp socket 4 just place flexible keypad 61 bottoms of antiseepage button piece 6 by key head 442, and the flexible keypad 61 of antiseepage button piece 6 just protrudes out outside the key hole 13 of location flashlight cylinder 1, and makes flashlight key switch place have splendid waterproof effect.

Moreover, above-mentionedly hold the raised line 51 that shell fragment 5 is dashed forward and established, in its formed chase 511 in bottom, the fixed bar 53 of can planting, and order holds shell fragment 5 and can have more firm clamping; Hold fin 52, the 52 ' edge of shell fragment 5 both sides again and can form zigzag 521,521 ', make tightr folder wedge at flashlight cylinder 1 inwall.

Again, the torch lamp cover cap 31 of present embodiment is square, is seated in the easy phenomenons that drop of rolling that produce in place such as desktop to avoid flashlight, to reduce flashlight, therefore causes damage, so its shape is also not exclusive; Moreover, lampshade revolves the projection 22 and the set guide channel 23 of external annulus of the bulb socket 2 that moves in the retractor device, the breach 331 that the ring rib 33 of lampshade 3 the is offered thing that matches, the prominent material 342 that the second ring rib 34 is set, the design department of its number all can be implemented with one (bar) or more than one (bar).
