Abstract

The utility model relates to a lamp holder, particularly a safety lamp holder which can prevent people's hands from touching the contact of the lamp holder. The top end ring of a containing groove of two halves of casing bodies is provided with a limit slot; one side of the front end of the spring sheet of the two conducting sheets is downwards sloped and formed with a conducting angle; the interior of the two halves of the casing bodies is provided with a bell-shaped lining; the top end of the bell-shaped lining forms a flanning inner conical shape, the edge forms a sawtooth shape, the inner edge forms a screw shape, and an insulating sheet on the bottom end is dented with a contact point; the sawtooth-shaped edge of the lining is scarf joint in the limit slot of the casing bodies; the contact point dented on the bottom end of the lining is contacted with the front end of a spring sheet of a conducting sheet. Accordingly, the utility model has high safety and convenient operation, and simultaneously, the service life can also be extended.

Description

Safety lampholder

The utility model relates to a kind of lamp holder, especially refers to avoid the safe lamp holder of staff contact cap contact.

At present, lamp holder (as shown in Figure 4) commonly used ties up to the identical shell structure of housing 5(two halves) upper and lower corresponding inner edge dig respectively and establish storage tank 52 and groove 51, be provided with screw thread 53 in this storage tank 52, two conducting strips 6 and this conducting strip 6 top bendings are set in the groove 51 extend in the storage tank 52, if with housing 5 in conjunction with and fix (two halves in conjunction with and tighten up), and with power line (not shown) connection conducting strip, turn-on power, and lamp holder borrows the screw thread 53 of storage tank 52 to screw, its lateral margin contacts with two conducting strips 6 respectively with the bottom, makes the bulb conduction; Its advantage is the convenience that more changes the bulb, still, because conducting strip is exposed in the storage tank 52, easily touch conducting strip 6 when children play, cause Danger Electric shock risk, for the people who is unfamiliar with electrical property, finger stretches into and fiddles with conducting strip 6 in the storage tank 52 when changing or check lamp holder, also can cause danger.

The purpose of this utility model provides a kind of safe lamp holder, in the storage tank of housing, be provided with a lining and within it edge bottom recess conductive junction point (contacting with the bulb bottom) is set.

The purpose of this utility model is achieved in that safe lamp holder comprises the two halves housing, two conducting strips, it is characterized in that: the storage tank top of above-mentioned two halves housing is equipped with a position-limited groove, shell fragment front end one side direction of above-mentioned two conducting strips has a down dip and forms a lead angle, in the storage tank of two halves housing, be provided with apical margin and be outer inner conical, zigzag along the limit, inner edge is screw thread, the bottom insulating trip is arranged with the bell lining of a contact, and the zigzag with this lining is embedded in the position-limited groove of housing along the limit, and end in contact before the shell fragment of a joint that the bottom of this lining is arranged with and a conducting strip.

Because adopt such scheme: finger stretches into the lining inner edge can not touch conductive junction point, reaches security purpose.

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

The three-dimensional exploded view of Fig. 1 the utility model exemplary embodiments.

The assembling schematic diagram of Fig. 2 the utility model exemplary embodiments.

The end view of Fig. 3 the utility model exemplary embodiments.

The end view of Fig. 4 prior art.

A kind of user mode figure of Fig. 5 the utility model exemplary embodiments.

The another kind of user mode figure of Fig. 6 the utility model exemplary embodiments.

As shown in Figure 1, present embodiment is made up of two halves housing 1,1 ' (shell structure that two halves are identical), two conducting strips 2,2 ' and one lining 3.

Two halves housing 1,1 ' the corresponding inner edge bottom scrapes out groove 11, and its inner rim top scrapes out storage tank 12, and this storage tank 12 is a semicircular in shape, and two halves housing 1,1 ' combination back constitute inner cylinder face and be equipped with one on its top encircles position-limited groove 13;

Two conducting strips 2,2 ' its bottom form grab 21,21 ', and the top then forms shell fragment 22,22 ', and having a down dip in shell fragment 22,22 ' front end one side direction again forms a lead angle 23,23 ';

Lining 3 is bell, and its apical margin is outwards to open, dimension shape in forming, periphery be zigzag along the limit 31, and the inner edge of lining 3 is screw thread 32, the bottom is an insulating trip again, this insulating trip place is arranged with one (conduction) contact 33(shrinkage pool less than finger);

System embeds conducting strip 2,2 ' in the groove 11 (consulting shown in Figure 3) during assembling, and the shell fragment 22,22 ' on its top is protruded in storage tank 12 root edges and the side, and the shell fragment 22(that stretches from the bottom of restriction consults shown in Figure 2) be slightly less than the total length of lining 3 to the distance of position-limited groove 13; 31 elder generations along the limit of lining 3 apical margins are embedded position-limited groove 13, and lining 3 rear sides are pressed into put in the groove 12, borrow the inclination lead angle 23 of shell fragment 22 front ends one side when being pressed into, be convenient to being pressed into of lining, again with 1 combination of two halves housing, promptly finish assembling (as shown in Figure 3), at this moment, the shell fragment 22,22 ' on conducting strip 2,2 ' top holds the side of lining 3 and (conduction) contact 33 of bottom, and then lining 3 relies on it along limit 31 build-ins in position-limited groove 13 with shell fragment 22,22 ' bearing force and be fixed in the housing 1,1 ';

Contact (prior art is not so gives unnecessary details) with power line by grab 21,21 ' during use, the bulb bolt can be gone among the lining 3, can transmit power supply and shinny, when bulb screws in, lining 3 tops are zigzag along the limit 31, then can increase friction and build-in force with position-limited groove 13, lining 3 is unlikely when bulb rotates and produces the phenomenon that can't screw in, and shell fragment 22,22 ' holds screw-in and back-out that lining 3 states do not influence bulb, and is easy to operate, reliable.

When finger stretches into lining 3, can only touch lining 3 peripheries, and can't touch shrinkage pool that the contact 33(contact of lining bottom is positioned less than the staff finger), so can avoid the generation of peril.

In addition, lining of the present utility model is also applicable to various different plug-in type and spiral lamp holder (shown in Fig. 5,6).

In sum: the utility model is except guaranteeing safety; Hold to the shell fragment normality, can prolong shell fragment useful life at lining root edge and lateral margin; The front end one side lead angle of shell fragment is convenient to being pressed into of lining, and lining top zigzag is along the limit, during to the screw-in bulb reliable and stable (increase frictional resistance); Lining is also applicable to plug-in type, different lamp holders such as spiral.
