Abstract

The utility model relates to an adjustable finger-ring with positioning means, in which a positioning device is arranged on the ring body which is combined by a plurality of truncated curved bodies, and the positioning device has the structure that a positioning rack is extended at the end part of one of the curved bodies, another curved body is provided with a slot for the positioning device to be inserted in and slide and is connected by a frame with a buckling hook capable of free rotation, and both side faces of the curved body are provided with hole seats containing elastic positioning sliders. When the truncated curved body finishes adjustment of the internal diameter, the buckling hook covers and clamps the positioning rack, the tail of the buckling hook and the upper limb of the slider form a contact mode, and the positioning effect is achieved.

Description

Adjustable ring with positioner

The utility model relates to a kind of Adjustable ring.

General ring internal diameter is divided into fixed and open, fixedly only can be worn on the finger of fixing someone, if be worn on the thin person of finger, the easily loosening slippage of ring, if be worn on the thick person of finger, ring is not easy on choosing, so it is fixed quite not convenient in the use, though and open can be for the size of adjusting the ring internal diameter, precisely because be just can reach by bending ring arc structure, so very not attractive in appearance in appearance, and its notch part is derived to have and is easily injured skin, wear uncomfortable, easily be hooked to shortcomings such as thing, make open ring loss percentage high, so open ring and fixed ring are neither too suitable for common people.

The purpose of this utility model is to provide a kind of wearer of convenience to be easy to adjust ring internal diameter size and the Adjustable ring with positioner of the location that is easy to lock.

The technical solution of the utility model is:

A kind of Adjustable ring with positioner, include ring body and positioner, the ring body blocks curved body by several and combines, this blocks curved body one end and is installed with slide rail, and assemble with the adjacent set mutual fit of chute of curved end of body that blocks, block a curved body and adjacent setting position, the curved body junction device that blocks in one of them, it is characterized in that: this positioner is to block curved body one end in one to be provided with ratchet-like location tooth bar, another blocks curved body one end and then offers chute, this location tooth bar inserts in this chute, on the curved body of blocking of chute both sides, be equipped with two corresponding driving rods, a buckling hook is pivoted on the driving rod, and the buckling hook leading edge is equipped with fixture block, this fixture block clip is gone into to locate in the tooth bar, this buckling hook end is extended with an afterbody, and in blocking the hollow form hole seat that curved body two sides are provided with projection, this seat bottom, hole is a closed form, insert elastomer and positioning sliding block in the seat of hole, this positioning sliding block surface is provided with projection, this projection appears outside the perforation that the hole seating face is opened, this positioning sliding block end exposes to outside the seat of hole, and is resisted against the buckling hook afterbody.

Effect of the present utility model is:

When the utility model uses in reality, mat blocks

curved body

11,12, the set chute 121 in 13 suit places, 131 and the location tooth bar 14 slippage, so that ring body 1 internal diameter forms the adjustable state to internal condensation or outside expansion, to be suitable for being linked on the finger section of different sizes, after adjusting ring body 1 internal diameter, stir positioning sliding block 5 earlier and make its front end retraction (as shown in Figure 3A) in hole seat 3, this moment, buckling hook 2 covered clip location tooth bar 14 downwards, release out positioning sliding block 5 again, positioning sliding block 5 front ends push in the articulated section of this buckling hook 2 because of the elastic force effect, the afterbody 23 of buckling hook 2 terminal extensions simultaneously forms stacked touching by shape (shown in Fig. 3 B) with slide block 5 upper limbs, so buckling hook 2 can not rotate again, reach the effect of location, and if desire to adjust ring body 1 internal diameter again, then stir positioning sliding block 5 earlier to be recessed in the hole seat 3, make buckling hook 2 terminal no interrupted and can freedom upwards start, can remove the locking condition of location tooth bar 14, whole positioning action is simple and practical.

Below only by specific embodiment, and assistant is with the detailed explanation of graphic do:

Fig. 1 is the three-dimensional appearance schematic diagram of the utility model.

Fig. 2 is the perspective exploded view of the utility model.

Fig. 3 A, 3B are its action schematic diagram when using of positioner of the utility model.

Fig. 4 is that the action schematic diagram is implemented in the side-looking of the utility model.

Please consult Fig. 1 simultaneously, shown in 2, ring body 1 of the present utility model blocks curved body 11 by several, 12,13 institutes are combined into, wherein block the dovetail shaped chute 111 that system has straight shape in curved body 11 both ends, for blocking curved body 12 in addition, the slide rail 121 that 13 1 ends are extended, 131 fits slip into, ring body 1 internal diameter can be formed inwardly dwindle or the outside adjustable state of expansion, for preventing slide rail 121,131 come off in chute 111, in chute 111, open a little shallow slot 112, slide rail 121, then establish prominent point 122 on 131,132 (prominent 122 in not shown), it slides wherein, and to fill up piece 113 that little shallow slot 112 front openings filling is closed, make slide rail 121,131 slide the prominent point 122 of middle mat, 132 cards end and can't come off;

In conjunction with consulting Fig. 3,4,

curved body

12 and 13 suit places blocked of the present utility model, be provided with a location device, this device lies in the location tooth bar 14 that blocks curved body 13 1 ends extension tool ratchet-like, it can stretch into to block in the chute of being opened in the curved body 12 15 does slippage, be equipped with two corresponding driving rods 123 in 15 liang of sides of chute and block curved body 12,2 of one buckling hooks are hubbed on the driving rod 123, make buckling hook 2 form and to make progress, downward can lift state, when wherein buckling hook 2 covers downwards, the fixture block 21 of being dashed forward and establishing with its leading edge, wear the small gap 151 that open in chute 15 the place aheads, clip goes into to locate in the ratchet of tooth bar 14, order location tooth bar 14 can slippage in chute 15, form locating effect, and buckling hook 2 leading edges are extended with the suitable big sheet 22 that lifts, can be easy to pull open this buckling hook 2 for hand, bend the arcuate socket seat 3 that body 12 two sides are provided with the hollow form of projection and block, its bottom is a closed form, elastomer 4 and positioning sliding block 5 are inserted in energy supply, these positioning sliding block 5 surperficial appropriate locations are provided with projection 51, projection 51 appears outside 3 perforation of opening 31 of hole seat, so can prevent that the improper of limited slip block 5 comes off, and the energy mat is stirred projection 51 makes positioning sliding block 5 slippage in hole seat 3, positioning sliding block 5 holds because of the elasticity of elastomer 4 under the normality, its end system exposes to outside the hole seat 3 slightly, and pushes in the articulated section of buckling hook 2, and button hook 2 is touched by shape with the formation of slide block 5 upper limbs in covering the terminal afterbody that is extended 23 in back, buckling hook 2 can not rotate again and start according to this, forms the effect of location.
