Abstract

The utility model relates to a novel grip device which is used for exercising the grip and moving the fingers and is composed of a pair of guide sleeves (2) and sliding posts (3) which can be mutually matched in the sliding way and are arranged on the corresponding position of an inner wall, a plurality of the upper grip covers (1) and the lower grip covers (4) of the spring seat (6), and a spring (5) which is correspondingly fixed on the spring seat (6). The structure is very simple, and the novel grip device can be disassembled and assembled very easily without any tool; when the utility model is used, according to the concrete situation of every person, the spring number which is suitable for the personal strength is chosen and then is assembled; so the utility model has the advantages of wide applicability and very low production cost.

Description

Spring-grib dumb-bells

The utility model relates to a kind of spring-grip that utilizes elastic resistance exercise grip activity finger.

Existing in the market spring-grip all has only a kind of changeless elastic resistance, and applicability is very limited.

Our purpose is to provide a kind of to the public can change elastic resistance, simple in structure, easy to assembly, novel spring-grip that production cost is low on demand.

This novel spring-grip is by the upper and lower two corresponding covers of holding, and is packed in the spring of holding cover and holding in the cover down and assembles.Hold cover and descend to hold be provided with on the correspondence position that covers inwall fairlead and traveller that is slidingly matched mutually and the spring base that installs spring last, spring just is packed on the spring base.

Available general engineering plastics single injection-molded is covered in holding up and down of this novel spring-grip, need not again through machined; Spring Card is contained in two and holds on the spring base of being preset on the cover inwall, is easy to dismounting, and it is very convenient to change spring, can select suitable spring to load onto use voluntarily by each one concrete condition.And must not use any instrument during dismounting.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:

Fig. 1 is the structural representation of a kind of embodiment of this novel spring-grip;

Fig. 2 is the transverse sectional view of such scheme.

Hold on this novel spring-grip cover (1) and under hold cover (4) preferably with engineering plastics injection mo(u)ldings such as ABS, can certainly make with other plastics or rubber.For making its good looking appearance and convenient the making, upper and lower hold cover (1) and (4) can be symmetrical expression be convenient to grasping, the cross section top is the hood-like body of microscler thin-walled of hemisphere face shape.Hold cover (1) and hold on the corresponding position of cover (4) inwall longitudinal midline perpendicular respectively one or two fairleads that are slidingly matched mutually (2) and the traveller (3) put down last.Its effect is the glide direction of holding cover (1) in the restriction and holding cover (4) down.The spring (5) of device in this novel spring-grip can be the sheet leaf spring.But the most economical, be suitable for be to use common garden cylindricality stage clip.So hold cover (1) and hold the spring base (6) that two or more also are being set respectively on corresponding mutually position of cover (4) inwall longitudinal midline down last, the two ends of spring (5) is packed in respectively on the spring base (6).Can select the equipped spring number that is suitable for own dynamics by each one concrete condition during use.When needed, can also be outside fairlead (2) and traveller (3), suit upper spring (5) is to increase elastic resistance.To be the garden pit-shaped more practical to be garden convex shape for spring base (6).We also can make the garden tubular with the garden convex of spring base (6), a garden shape magnet (7) is embedded in its inner chamber, and offer a through hole (8) upper and lower the holding on cover (1), (4) wall on its top, so that the magnetic line of force of magnet (7) appears.Hold cover (1) and hold on the outer wall of cover (4) down last, preferably lay some bur grains (9), when using this novel spring-grip, these bur grains (9) just can stimulate the centre of the palm and finger, promotion sporter's blood circulation.

Claims

1, utilizes a kind of spring-grip of elastic resistance exercise grip activity finger, it is characterized in that: it by hold on corresponding cover (1) and under hold cover (4) and spring (5) assembles, last hold cover (1) and hold down on the correspondence position of cover (4) inwall fairlead (2) and traveller (3) and the spring base (6) that is slidingly matched mutually is being set, spring (5) is packed on the spring base (6).

2, a kind of spring-grip according to claim 1, it is characterized in that: on to hold cover (1), hold cover (4) down be that the cross section top that is symmetrical expression is the hood-like body of microscler thin-walled of hemisphere face shape, hold cover (1) and hold down that perpendicular respectively one or two fairleads that are slidingly matched mutually (2) and traveller (3) and correspondence put are being provided with two or more spring base (6) on the relative position of cover (4) inwall longitudinal midline last, the two ends of spring (5) is packed in respectively on the spring base (6).
