Description

Head mounted working lamp

The utility model relates to a kind of working light of wearing.Being specially adapted to the railway operation personnel uses during operation in night or tunnel.

Chinese patent CN86201483 discloses a kind of with power supply, light fixture and cap trick body molten " light band lamp holder hoop " for one, and for weight reduction and volume, it need adopt battery No. 5, so it is mainly used as the floor light light source.In addition, its occupation mode is single, and inconvenience is used with safety cap, cotton-padded cap etc., is unsuitable for the outfield operation.

The purpose of this utility model provides a kind of simple in structure, is convenient to wear working light with multiple cap body is used.

The utility model is realized in the following manner:

It is by lamp holder, and battery case and headband three parts are formed, and plug-in card particularly is housed on lamp holder, and plug-in card connects with the trip bolt axle with lamp holder, in the place ahead of headband insert library is housed.It can directly be inserted on the safety cap by plug-in card and use, and also can cooperate with headband to be worn over the upward use of cotton-padded cap, single cap or head.Lamp holder can be made angular adjustment around screw axis, by the scope of horizontal direct projection position adjustments is: when lamp holder and headband are used, rotate up 75 °, be rotated down 60 °, when lamp holder and safety cap are used, rotate up 10 °, be rotated down 90 °.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the schematic diagram that the utility model and safety cap are used.

Fig. 3 is the interior focusing apparatus structure schematic diagram of the utility model lamp holder.

Fig. 4-1,4-2,4-3 are the locking device structural representation of battery case.

Fig. 4-1 is the partial view of battery case.

Fig. 4-2 is the A-A profile of Fig. 4-1.

Fig. 4-3 is that the B of Fig. 4-2 is to view.

Lamp holder in the drawings, 1, battery case, 2, headband, 3,, 4, trip bolt axle, 5, plug-in card, 6, safety cap, 7, the lamp socket brace, 8, focusing knob, 9, steep frame down, 10, on steep frame, 11, locking button, 12, battery case, 13, metallic sheath, 14, lock hook, 15, lamp socket, 16, pre embedded bolt, 17, spring leaf, 18, insert library, 19, power switch button.

The utility model is formed (referring to Fig. 1) by lamp holder 3, battery case 12, headband 2 three parts.Plug-in card 5 is housed on lamp holder 3, and plug-in card 5 connects with lamp holder 3 usefulness trip bolt axles 4, in the place ahead of headband 2 insert library 18 is housed.Plug-in card 5 itself can be made the rubber-like plug-in card, also can load onto spring leaf 17 in plug-in card 5 grooves, so that tighten with insert library or shade.

Lamp holder 3 can be made angular adjustment around screw axis 4, by the scope of horizontal direct projection position adjustments is: when lamp holder 3 and headband 2 are used, rotate up 75 °, be rotated down 60 °.(see figure 2) when lamp holder 3 and safety cap 6 are used.Rotate up 10 °, be rotated down 90 °.

Interior focusing device (see figure 3) of the present utility model by last bubble frame 10, steep frame 9 down and focusing knob 8 is formed, on last bubble frame 10, pre embedded bolt 16 is housed, and have the locating hole that lamp socket brace 7 is played the role of positioning, steeping the hole of an alignment pin being housed on the frame 9 and matching down with pre embedded bolt 16.The interior focusing device is contained in the below of lamp holder 3, by promoting focusing knob 8, can drive lamp socket 15 and move forward and backward, and reaches the focusing purpose.This focus control has the better waterproof energy, and it is big also to have focusing range simultaneously, characteristics such as governing speed is fast.

The locking device of battery case (seeing Fig. 4-1,4-2,4-3) is made up of locking button 11 and lock hook 14, a pre-buried screw rod in locking button 11, the end that screw rod cooperates with lock hook is equipped with metallic sheath 13, and locking button 11 is contained on the battery case lid, and lock hook 14 is fixed on the inwall of battery case.By promoting locking button 11 move left and right, drive metallic sheath 13 lock hook 14 inside and outside slips, realize closing box and the action of opening box.

Power supply adopts R20 type dry cell (or to its voltage, similar high energy or the chargeable various alkaline battery of volume) three joints, and bulb voltage is 3.8V.

During use, battery case hangs on the belt, and lamp holder is connected with the plastic sheath line with battery case.

The utility model has the advantages that simple in structurely, handsome in appearance, have multiple occupation mode, can directly be inserted on the safety cap and use, also can cooperate with headband to be worn over that cotton-padded cap, single cap or head are upper to be used.
