Abstract

The utility model relates to a device for strengthening wrist, particularly a device for exercising the strength of the wrist, which belongs to the body-building field of physical training. The device for strengthening wrist is composed of an external cylinder, a mandrel, a torsional spring, an intermediate ring, a stop ring, a slide block, positioning screws, limiting screws, an end cover, etc. All the components are arranged in the external cylinder (a handle). The intermediate ring is provided with scale marks, the handle (the rolling texture portion of the external cylinder) is provided with corresponding scale marks which are divided into two levels so that users can adjust the strength by themselves.

Description

Divece for strengthening wrist

A kind of body-building forearm flexor exerciser belongs to the vigorous and graceful field of physical culture, particularly a kind of a kind of apparatus of the wrist power muscle of exercising.

Fitness facility does not in the past still have the muscular effect of special exercise forearm, can only exercise with serving or with dumbbell, and promptly inconvenience and effect are not good yet.

The purpose of this utility model is to overcome above technical deficiency, and the wrist power that provides a kind of moment of torsion opposing contraction of muscle of utilizing torsionspring to produce, thereby stimulates forearm muscle and reach the exercise purpose.

Describe with by way of example below in conjunction with accompanying drawing.

Fig. 1 shows body-building forearm flexor exerciser structure chart.

Fig. 2 shows body-building forearm flexor exerciser A-A profile.

Fig. 3 shows that body-building forearm flexor exerciser C is to view.

Fig. 4 shows body-building forearm flexor exerciser B-B profile.

Among the figure, the 1-urceolus; The 2-mandrel; The 3-torsionspring; The 4-adapter ring; The 5-locating snap ring; The 6-slide block; The 7-dog screw; 8-limit companion screw; The 9-end cap

The body-building forearm flexor exerciser is made up of urceolus (1), mandrel (2), torsionspring (3), adapter ring (4), locating snap ring (5), slide block (6), dog screw (7), stop screw (8), end cap (9) etc.Place adapter ring (4) in the middle of the urceolus (1), in have one with the corresponding fin of mandrel (2) groove dimensions, can keep adapter ring (4) relative static with mandrel (2).Adapter ring has graduation mark on (4), on the handle (urceolus) corresponding scale is arranged.Two circumferential slideways are arranged on the mandrel (2), can make handle and mandrel (2) axial limiting (shown in the accompanying drawing 2).Locating snap ring (5) is fixed with dog screw (7) and handle, and has groove, and card is put torsionspring (3), and other end locating snap ring (5) has twice axial groove (promptly dividing two gears), adjusts dynamics voluntarily for the user.

Body-building forearm flexor exerciser length overall 270mm, handle long (it is long that urceolus rolls reticulate pattern) 127mm, diameter 30mm, urceolus wall thickness 3mm, mandrel are an overall structure, long 220mm, 24mm greatly directly, with the urceolus internal diameter be matched in clearance; Stop ring external diameter 24mm, internal diameter 10mm and mandrel path are matched in clearance, to guarantee that rotation flexibly.

The body-building forearm flexor exerciser is simple in structure, and volume is little, and all member is hidden in the extroversion (handle), and safe in utilization, reliable, convenient, common metal machining can realize.

When using the body-building forearm flexor exerciser, two hand-tight handles, left hand backward, the right hand forward, left slider (6) and mandrel (2) dieback like this, left side torsionspring (3) (dextrorotation) is inoperative, right handles drives locating snap ring (5), torsionspring (3) relatively rotates with mandrel (2), and right side torsionspring (3) produces torsion, the opposing wrist power.On the contrary, also as a same reason.More than said left side, right side be to set for convenience of explanation, during actual the use, about needn't considering, the body-building forearm flexor exerciser can horizontally be held, and also can erect and hold.Left and right sides wrist is alternately reversed to different directions, can reach the purpose of exercise wrist power muscle.

Claims

1, a kind of body-building forearm flexor exerciser, by the interior insert mandrel of urceolus (1) (2), mandrel (2) is installed torsionspring (3), it is characterized in that placing adapter ring (6) at urceolus (1) middle part, is provided with and the corresponding fin of mandrel (2) groove, make adapter ring (4) relative static with mandrel (2), two circumferential slideways are arranged on the mandrel (2), make handle and mandrel (2) axial limiting, locating snap ring (5) has groove, card is put torsionspring (3), goes up at mandrel (2) and rotates;

2, body-building forearm flexor exerciser according to claim 1 is characterized in that the corresponding graduation mark of delineation on said adapter ring (6) and the handle.
