Description
Technical field
The utility model relates to a kind of finger spring-grip.Be applicable to body-building apparatus.
Background technology
The Chinese patent that the patent No. is 01259733.3 provides a kind of spring-grip, and this spring-grip mainly comprises: four finger pressure bodies, and these four adjacent arrangements of finger pressure body and inner face respectively are convexly equipped with the jack-post that an end has folder gap groove, cone embedding edge; A palm laminate, this palm laminate inner face is convexly equipped with equally several and is the traveller of alternate setting with jack-post, and this traveller end also forms and presss from both sides the gap groove and bore the embedding edge; Some flexible members, these some flexible members are sheathed on each jack-post and traveller; A middle pedestal, in this, the quantity of the corresponding jack-post of pedestal and traveller is offered some axle slide openings that run through up and down, and the cone embedding edge on the corresponding jack-post of the end inner edge of this each axle slide opening and traveller forms embedding and stops edge; Form one by above-mentioned member and have variability and comfortableness, certain spring-grip is assembled easily, located to easy to use having concurrently again.Yet this patent Elastic element spring is outside exposed, easily crushes user's palm, and this patent function singleness, impracticable.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provides a kind of finger spring-grip simple in structure, easy to make, can effectively avoid crushing the user, and safe and reliable.
The technical scheme that the utility model adopts is: a kind of finger spring-grip, it is characterized in that: this spring-grip is by four finger pressure bodies, a palm laminate, and a middle pedestal composition, axially be shaped with the sliding cylinder body on each finger pressure body, be shaped with the oblate cylinder that slides on palm laminate; Described middle pedestal upper surface is shaped with and slaps laminate oblate blind hole corresponding to oblate cylinder of sliding, and lower surface is shaped with four round blind holes corresponding with sliding cylinder body on the finger pressure body, and palm laminate is plugged in oblate blind hole, and the finger pressure body is plugged in round blind hole; Between described finger pressure body, palm laminate and corresponding blind hole, spring is housed.
Be set with sealing ring on the sliding cylinder body of the oblate cylinder of the slip of described palm laminate and finger pressure body.
All have passage on the hole wall of described oblate blind hole and circle blind hole bottom.
Described oblate blind hole and circle blind hole are inserted the sound-producing device because of the Air Flow sounding.
But be shaped with the cavity of storing articles in described middle pedestal, and be furnished with openable lid.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to make, and spring is inserted in blind hole, avoids spring to crush the user.Insert the sound-producing device because of the Air Flow sounding in blind hole, in use, Air Flow in blind hole, drive sound-producing device, improves and use enjoyment.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is a kind of finger spring-grip, and by four finger pressure bodies 3, a palm laminate 2, and a middle pedestal 1 forms, and is shaped with cavity in middle pedestal 1, and is furnished with openable lid, is convenient to deposit the article such as change.Axially be shaped with the oblate cylinder that slides on palm laminate 2, middle pedestal 1 upper surface is shaped with the oblate blind hole 12 corresponding with slapping the oblate cylinder of laminate 2 slip, and the oblate cylinder of palm laminate 2 slip is plugged in oblate blind hole 12.Axially be shaped with the sliding cylinder body on each finger pressure body 3, middle pedestal 1 lower surface is shaped with four round blind holes 11 corresponding with sliding cylinder body on finger pressure body 3, and finger pressure body 3 sliding cylinder bodies are plugged in round blind hole 11.Between finger pressure body 3 and corresponding blind hole, a spring 4 is housed in this example, between palm laminate 2 and corresponding blind hole, three springs 4 is housed, be uniformly distributed.
For use enjoyment is provided, in this example, the finger spring-grip can in use send the sound.All have passage 13 on the hole wall of oblate blind hole 12 and circle blind hole 11 bottoms, insert the sound-producing device because of the Air Flow sounding in oblate blind hole 12 and circle blind hole 11, as whistle.Be set with sealing ring 5 on the oblate cylinder of slip of palm laminate 2 and the sliding cylinder body of finger pressure body 3.When compressing palm laminate 2 and finger pressure body 3, drive Air Flow in corresponding blind hole, make whistle send the sound.The different whistles of can packing in each blind hole, thus the different sounds occur.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
