Description

Lamp head

The utility model refers to a kind of lamp head that can not come off easily that bulb closely can be screwed, to reach safety requirements especially relevant for a kind of lamp head.

The lamp holder of commonly using can be divided into two kinds, cylindric (as shown in Figure 1) that wherein a kind of main body is formed in one, when molding, need below main body 10 inside screw thread 11 fully during moulding the not shown threaded mold extraction that goes out, after avoiding main body 10 to solidify typing, can't extract out, therefore the screw thread 11 in the main body 10 can't cooperate fully with the screw thread on the bulb, and cause bulb firmly to be embedded on the main body, and the bulb obscission very easily takes place, cause user's danger; The second way (as shown in Figure 2), be to be divided into two block shapes in main body 12 lower portions, its first block, 121 tops have an edge clipping 122, and this edge clipping 122 can be sticked on second block 123, by this so that both be combined into one, though this kind combination can be improved the defective in the molding commonly used of earlier figures 1, but its first block 121 is only chimeric with its edge clipping 122 and second block 123, both can't fit fully and leave gap existence, and the danger that makes this structure still have bulb to come off takes place.

Main purpose of the present utility model is to provide the lamp head of a kind of sound construction and good conductivity, wherein screw by screw thread in the collar and bulb, and by annular groove and the holding mutually of microscler raised line of the annular protruding rib of its outer rim and microscler groove with the lower body part inner edge, by this to strengthen the combination degree of the main body and the collar, so that the collar or bulb can not come off easily, while appropriate location on this collar is provided with one and runs through slotted eye, so that the ground wire of this bulb is able to engage with sharp copper sheet on the main body, be beneficial to conduction by this.

A kind of lamp head of the present utility model includes a main body, it is characterized in that,

Described main body, be divided into upper and lower two parts, its top is the groove shape, so that outside ccontaining several pieces sharp copper sheet are revealed in it, and be provided with the space that electric wire passes through, on it and press and to put engaging one loam cake is arranged, below part inner edge is provided with an annular groove, and both sides, annular groove top are respectively equipped with a microscler raised line;

The described collar, be placed in described main body below, the its inner rim place is provided with the screw thread that screws bulb, the outer rim place be provided with one with the opposed annular protruding rib of described annular groove, and both sides, annular protruding rib top respectively be provided with one with the opposed microscler groove of described microscler raised line, with closely chimeric, respectively be provided with one in two microscler groove tops and run through slotted eye with described main body.

Described lamp head is characterized in that, the described collar is hollow tubular.

Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows feature of the present utility model:

Description of drawings:

Fig. 1 is the exploded view of the lamp head commonly used;

Fig. 2 is the exploded view of the another kind of lamp head commonly used;

Fig. 3 is STRUCTURE DECOMPOSITION figure of the present utility model;

Fig. 4 is a sectional exploded view of the present utility model;

Fig. 5 is the front section view after the utility model combination;

Fig. 6 is the side sectional view after the utility model combination;

Fig. 7 is a three-dimensional combination figure of the present utility model.

As shown in Figure 3, it is the utility model exploded view, it mainly is made of a main body 20, a loam cake 21 and a collar 30, sectional exploded view as shown in Figure 4, wherein main body 20 is divided into upper and lower two partly, its upper part be the groove shape and by this so that its in several pieces ccontaining sharp copper sheet 23 can be exposed to surface, main body 20 top, simultaneously and give the space of electric wire 22 processes, loam cake 21 is pressed and is put the top that is covered on main body 20, with compressing electric wire 22 it is pierced through by sharp copper sheet 23 by this and forms the conduction shape; Main body 20 lower internal edge are equipped with a collar 30, the collar 30 inner edges are provided with screw thread 31 also by this to screw a bulb 40, its outer rim bottom appropriate location is provided with an annular protruding rib 301, and respectively be provided with a microscler groove 302 in both sides, annular protruding rib 301 top, and be provided with and above-mentioned annular protruding rib 301 in lower body part inner edge appropriate location, microscler groove 302 opposed annular groove 201 and microscler raised lines 202, by this so that the collar 30 is able to chimeric closely main body 20 lower internal edge of going into, and bulb 40 can not come off easily, be provided with one in addition in two microscler grooves, 302 tops and run through slotted eye 303, had with the ground wire that is placed in the bulb 40 in it by this partly to be exposed to outside the collar 30, and contact with sharp copper sheet 23 of main body 20 inner edges and conduct electricity.

Fig. 5, Fig. 6 is front and the side sectional view of the utility model after combination, also please contrast the exploded view of Fig. 3 simultaneously, the collar 30 is that main body 20 inner edges are gone in holding after being combined with bulb 40, while is also chimeric with the annular groove 201 and the microscler raised line 202 of main body 20 inner edges by the annular protruding rib 301 and the microscler groove 302 of its outer rim, by this so that both are chimeric closely is integral, and bulb 40 and run through slotted eye 303 by two and be able to engage with sharp copper sheet 23 of main body 20 inner edges, and because the collar 30 is a hollow tubular, make the live wire on bulb 40 tops slightly protrude out the upper surface of the collar 30 and contact, use smoothly and conduct electricity with sharp copper sheet 23.

Fig. 7 is a constitutional diagram of the present utility model, contrast the exploded view of Fig. 3 again, after the collar 30 screws bulb 40, main body 20 inner edges are gone in holding in the lump again, and both are combined as a whole, and the while is chimeric by annular protruding rib 301 and annular tongue 201, and the engaging of microscler groove 302 and microscler raised line 202, to strengthen the conjugation of the main body 20 and the collar 30, to stop the situation generation that the bulb 40 or the collar 30 come off, effectively reach safety requirements by this.

The utlity model has following effect:

Because main body outer rim of the present utility model is provided with annular protruding rib and elongate slots Ditch, main body bottom are provided with cannelure and microscler raised line, so as to strengthen bulb with The combination degree of main body, again because main body is provided with sharp copper sheet, so that Bulb is electrically connected with lamp holder, is beneficial to conduction, and is therefore, of the present utility model Lamp holder is difficult for causing bulb to come off, its good conductivity.
