Abstract

The utility model relates to a finger ring type portable flashlight, the illumination intensity range of which is small. The utility model does not affect other people for learning and writing at night. An integrated finger ring 5 is arranged on a casing of the flashlight, and an elastic conductive reed 7 is arranged between one end of a luminous diode 10 and a micro cell. Two resistors 8 with different resistance values are connected with the other end of the luminous diode in parallel, and the two resistors respectively have contacts 11 on a seat body in the assembled position of the casing and a lamp holder. An electrode plate 12 respectively contacted with the contacts 11 is arranged on the inner wall of the casing when the lamp holder rotates, and the electrode plate is connected with a polar elastic plate between the micro cell and the bottom of the casing. The utility model realizes the on-off action by rotating the lamp holder, and the night illumination for studying at night does not affect other people's rest.

Description

Ring torch on finger

The utility model relates to a kind of finger ring type Pocket torch of writing study night of specializing in.

In the dormitory or family, in order not influence other people night's rest and to think that study writes; The needs that desk lamp arranged are shield in addition, or adopts a hand-held torch, only pipe so also have a surplus influence of light other people have a rest, helplessly lie in and learn in the quilt, but write inconvenience.

The purpose of this utility model is to avoid weak point in the above-mentioned prior art, and provides a kind of illumination zone little finger ring type Pocket torch, does not influence other people rest night and can learn to write.

The purpose of this utility model can reach by the following technical programs: by shell, bulb, lamp socket, the torch that battery and switch are formed, the ring ring that formation " 8 " font is arranged on the plastic casing, between one utmost point of micro-led bulb and the minicell negative pole polarity reed is housed, the different resistance of another of bulb 2 resistances extremely in parallel, 2 resistance is in shell and lamp socket assembling contact 11 respectively on the lamp holder, when lamp socket in rotation process, the pole piece 12 that can contact respectively with contact is arranged on inner walls, at the bottom of this pole piece and battery and the shell between the polarity shell fragment connect.

Protruding, the concave volume of symmetry assembling upwards can be arranged in 11 weeks of contact having between above-mentioned lamp socket and the housing, concave volume on the housing, every side can have 3 adjacent concave volumes.Convex body also is a symmetric arrangement on the lamp socket, 1 of every side, and wherein 2 contacts 11 can be in the perpendicular bisector both sides of the middle concave volume line of symmetrical concave volume, and pole piece 12 can be on the perpendicular bisector of line.

The utility model can have following effect compared to existing technology: this torch is a pocket, illumination zone is little, night, study did not influence other people, because on the power circuit and connect 2 current-limiting resistances that resistance is different, each resistance can be connected with contactor respectively, cell voltage just often uses high resistance measurement work, can use the work of low resistance resistance after the battery step-down, can make torch front and back brightness unanimity.

Fig. 1 is the complete section diagrammatic sketch of this torch.

Fig. 2 is a relevant connection diagrammatic sketch such as lamp socket 9 and bulb 10 on Fig. 1.

Fig. 3 is Fig. 1 upper edge ring ring 5 section diagrammatic sketch.

Fig. 4 is the diagrammatic sketch that is connected of bulb 10 resistance 8 and contact 11 on Fig. 1.

Fig. 5 is circuit theory diagrams.

To be described further this torch below in conjunction with accompanying drawing:

By shell: the torch that bulb, lamp socket, battery and switch are formed.It is that the ring ring 5 that forms figure of eight opening with housing is arranged on the plastic casing 4 that this torch adopts, and between a utmost point (negative pole) of light emitting diode bulb 10 and the negative pole of minicell 1 polarity shell fragment 7 is housed.Another level (positive pole) 2 resistance 8 that resistance is different in parallel of bulb, two resistance are in to be welded with respectively on the lamp holder with lamp socket 9 assemblings at shell 4 and are communicated with two convex body contacts 11, can distinguish contacted switch concave volume pole piece 12 when lamp socket has with two contacts 11 on inner walls in rotation process, this shell fragment with at the bottom of battery and the shell between polarity sheet 3 be connected.

Above-mentioned torch in rotation process, is finished switch motion in order to realize lamp socket, can between lamp socket and shell convex-concave (2, the 6) body that the symmetry assembling is upwards arranged in 11 weeks of contact arranged, and switch location concave volume 6 every sides can have 3 adjacent concave volumes on the housing.2 contacts 11 can be in the perpendicular bisector both sides of the recessed line in the centre of symmetrical concave volume 6, and pole piece 12 can be on the perpendicular bisector of line, and 2 contacts 11 should equate with the arc distance of adjacent concave volume 6.As shown in Figure 4, for easy for installation, with shell lamp socket cooperation place axially on can be made into 6 grooves or 4 grooves of symmetry, can make things convenient for lamp socket to insert, when being positioned at centre concave volume 6, convex body 2 is in "off" state, can make the bigger or less resistance access circuit of resistance when forwarding two concave volumes in the outside to, simultaneously circuit is connected and is made lamp bright.
