Description

The Glass spring earpiece device of improvement

The utility model relates to a kind of earpiece.

At present, known Glasses structure as shown in Figure 1, is to articulate mirror foot A11 by mirror holder A10 both sides to be formed, and following shortcoming is arranged: 1. glasses meeting nature landing when wearing; 2. glasses are worn mirror foot A11 clamping and are reached face in the ears and can cause pain, because the mirror of glasses foot A11 has integrated structure, and one of problem be mirror foot A11 that eyeglasses frame A10 articulates too reclining cause holding force in the outside not enough, or only collude slightly to hold at the hangers A12 of glasses mirror foot A11 end and fail to have concurrently holding function in the ears, cause the easy landing of glasses or come off, and problem two be too banding and oppress and reach the face side position in the ears of glasses mirror foot A11, wearer's skin is not felt well because of being subjected to oppress for a long time, moreover, the making of traditional eyewear mirror foot A11, by integrated kenel, can't make elasticity and open adjustment outward, so can cause the wearer that as above sense of discomfort is arranged when wearing glasses.

In view of this, the purpose of this utility model provides a kind of Glass spring earpiece device of improvement, and it can make holder fit snugly in the storage tank, and mirror can be elasticity completely and opens outward.

The purpose of this utility model is achieved in that a kind of Glass spring earpiece device of improvement comprises pivot joint block, holder, flexible member, bolt and mirror foot, wherein the pivot joint block back segment is provided with group connecting part, leading portion articulates lug, be provided with screw at the group connecting part end, fixed seating is located on the pivot joint block, be equipped with through hole on it, flexible member system is arranged on the holder rear, the one end is also replaced rear end face at holder, bolt stretches through in the through hole of flexible member and holder, and spins with holder, and the mirror foot is socketed on the holder, its front end side wall is provided with a baffle plate, be provided with storage tank at this leading section, it is characterized in that: the holder surface has annular latch, and the storage tank inwall wringing fit inlay card of the latch of holder and mirror foot location.

Because adopt such scheme: mirror can be opened outward completely, and the people who is suitable for different face width wears, all in the mirror foot, structure has the outward appearance integrality to each member, and member is also simple simultaneously, assembling is also convenient.

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

Fig. 1 is the utility model exemplary embodiments exploded view;

Fig. 2 is the utility model exemplary embodiments combination synoptic diagram;

Fig. 3 is the utility model exemplary embodiments cut-open view;

Fig. 4 is the utility model exemplary embodiments assembled sectional view;

Fig. 5 is the utility model exemplary embodiments combination extratensive type attitude figure;

Among the figure: A10. mirror holder A11. mirror foot A12. hangers A13. end face 1. pivot joint blocks 10. group connecting parts 100. screws 11. articulate lug 2. holders 20. through holes 21. latches 3. flexible members 4. bolts 5. mirrors foot 50. baffle plates 51. storage tanks

As shown in Figure 2, present embodiment is by a pivot joint block 1, one holder 2, one flexible member 3, members such as one bolt 4 and mirror foot 5 are formed, wherein pivot joint block 1 back segment is set to group connecting part 10, leading portion is provided with and articulates lug 11, the end system of group connecting part 10 is provided with screw 100, one holder 2 is to be set on the pivot joint block 1, it is metal material, wear 4 through holes 20 therebetween, the internal diameter of this through hole 20 is slightly larger than the group connecting part 10 of pivot joint block 1, this holder 2 rectangular blocks surface circular row latch 21, one flexible member 3, its front end system is resisted against holder 2 rear end faces, and a bolt 4 is to stretch through at flexible member 3 and holder 2, and be rotated with mutually with pivot joint block 1 in group is located at holder 2 through holes 20, one mirror foot 5 is to be socketed on the holder 2, and its front end side wall convexes with a baffle plate 50, is provided with storage tank 51 at leading section, the external diameter of the inner width of this storage tank 51 and holder 2 is almost equal, is to be with holder 2 to closely cooperate for this storage tank 51.

During combination, shown in Fig. 2-4, group of pins 10 with pivot joint block 1 inserts in the through hole 20 of holder 2 earlier, be slightly larger than the group connecting part 10 of pivot joint block 1 because of through hole 20, so pivot joint block 1 can slippage in through hole 20, secondly bolt 4 passes the through hole 20 of flexible member 3 and holder 2, and spin mutually with the screw 100 of the tail end group connecting part 10 of inserting the pivot joint block 1 in through hole 20 of pulling, again above-mentioned group of component groups of establishing established in the storage tank 51 of mirror foot 5, because of the internal diameter and the holder external diameter of storage tank 51 are almost gone up together, so need holder 2 is forced in the storage tank 51, and when the inwall of borrowing 21 pairs of storage tanks 51 of latch of holder 2 forms the buckle retaining, holder 2 is closely cooperate to be installed in the storage tank 51, unlikelyly deviates from, so can finish assembling.

When wearing use, as Fig. 4, shown in 5, because the pivot joint lug 11 of pivot joint block 1 is to be pivoted mutually with mirror holder A10, when face's width during greater than the inner width of two mirrors foot 5, this two mirrors foot 5 outwards elasticity is opened outward, system borrows the acies face that the supports A13 of baffle plate 50 end faces of mirror foot 5 front ends and mirror holder A10 to support each other and forms fulcrum, so when opening outside the mirror foot 5, the pivot joint block 1 affixed with mirror holder A10 just can spur bolt 4 and compression elastic element 3, but pivot joint block 1 is the 20 interior slippages of holder 2 through holes then, make mirror foot 5 can be elasticity and open setting outward, to reach the effect that all can comfortablely wear for the wide wearer of different shapes of face, Zheng Ti member is installed with in mirror foot 5 again, can not dash forward superfluous and integrality destruction mirror foot overall appearance by generation component.

The utlity model has following advantage:

1, member is simple, and is easy to assembly, can reduce manufacturing cost.

2, each member all is arranged on the integrality that the mirror foot is interior, can guarantee mirror foot overall appearance.

3, borrow the latch of holder that the inwall formation buckle gear of mirror foot storage tank is held, holder is closely joins Close and be installed in the storage tank, can be firmly to connect and establish.
