The specific embodiment

See also Fig. 1 to Fig. 3, in the ears key-ring structure provided by the utility model, mainly comprised a disk body 10, pair of switches auricle 20, number key-ring ring 30, a chain coil structures 40 and a latch 50.

Disk body 10 outer circle walls are provided with indent groove 11, and locate to be provided with the two broad openings 12 that separate above groove 11; Can cooperate Fig. 2 A, disk body 10 central authorities form center of circle district 14, and form a perforation 15 vertically upward in center of circle district 14, and the center position of corresponding two openings 12 is respectively equipped with a pin-and-hole 13.And in this embodiment, form hollow bulb 16 in the middle of the disk body 10, decorate body 60 to install one.In addition, above disk body 10, separate two openings 12, and the centre position of two spacers 17 forms groove 171 relatively with a pair of spacer 17.

Two switch auricles 20, its root edge formation is dwindled district 24 and can be positioned in the opening 12; Be provided with stepped perforation 201 (can referring to Fig. 3) in each switch auricle 20 inside from top to bottom, pass for the pin 21 that draws that is installed with spring 22 respectively; Each draws pin 21 ends to pass pin-and-hole 13 in disk body 10 center of circle district 14 and riveted and fixed one switch auricle 20, makes that switch auricle 20 can be along drawing axially drawing of pin 21 to remove mouthfuls 12, and be that the center rotates to draw pin 21.Spring 22 provides the switch auricle 20 restoring forces, and maintained switch auricle 20 often is combined on the opening 12.

Chain coil structures 40 tops are a fastener 41, and the below forms the groove 171 on the spacer 17 that connecting portion 42 passes disk body 10 tops, to stretch into perforation 15 tops in the center of circle district 14, and rivet mutually with latch 50 ends that 15 belows of boring a hole are certainly stretched into, can not move and make the connecting portion 42 of chain coil structures 40 be fixed in 17 of two spacers.

Latch 50 runs through decoration body 60 and two and is divided into the pad 61 of decorating body 60 upper and lowers after perforation 15 belows in disk body 10 center of circle district 14 are stretched into through hollow bulb 16, making and decorating body 60 latch 50 to be the center rotation.

Key-ring ring 30 has a snap fastener 31 in order to assembling key, and this snap fastener 31 has bigger round end portion 312 of a diameter and the less neck 311 of a diameter.The diameter of round end portion 312 is greater than groove 11 width, and neck 311 diameters are less than groove 11 width, makes snap fastener 31 can be combined on the groove 11 of disk body 10 and can not come off.

In use, can be referring to shown in Figure 4, one switch auricle 20 is in reverse to disk body 10 openings 12 outer drawing, make root edge dwindle district 24 and break away from opening 12, again according to the rotating switch of direction shown in arrow A auricle 20 among the figure, the neck 311 of key-ring ring 30 snap fasteners 31 can be slipped in the groove 11 to appear opening 12, and utilize round end portion 312 diameters greater than groove 11 width, the key-ring ring 30 of feasible combination can not come off from disk body 10 but can move along groove 11.As will take out key-ring ring 30 time, also be that same console switch auricle 20 appears opening 12, can take out.

Notably, chain coil structures 40 of the present utility model is to rivet mutually with latch 50 and sheet 17 restriction that is positioned can not be moved, and it is comparatively convenient in use to make.Simultaneously, because the setting of latch 50 can be assembled a rotating decoration body 60 in the hollow bulb 16 of disk body 10, make whole key-ring structure more attractive in appearance interesting.

The person of advancing referring to Fig. 5 to Fig. 7, is the another kind of embodiment of the utility model, and wherein disk body 210 has groove 211, and groove 211 tops form opening 212, and form the groove 217 of location usefulness in the middle of opening 12; Offer stepped perforation 215 in the center of circle portion 214 in the disk body 210, can be referring to Fig. 6 A.Chain coil structures 240 tops are suspension ring 241, and the below forms a junction 242; Connecting portion 242 is combined on the opening 212, and protrudes a switch auricle 220 in both sides on respectively, and central authorities form one and can be socketed on location, disk body 210 tops with the projection 243 in the groove 217.One latch, 250 covers are unified springs 222 and are stretched into from stepped perforation 215 belows of disk body 210, its terminal and connecting portion 242 riveted joints.

In use, switch auricle 220 being in reverse to disk body 210 openings 212 outer drawing, making connecting portion 242 break away from opening 212, is center rotary switch auricle 220 with latch 250 again, can make opening 212 appear, to take out or to insert key-ring ring 30.

The function series of spring 222 provides the restoring force of switch auricle 220, makes connecting portion 242 keep being combined on the opening 212 of disk body 210.

To sum up institute is old, and ears key-ring provided by the utility model makes the chain coil structures promptly be positioned after the meeting in group, and more preceding case is more progressive.
