Description

The back drawing type fitness equipment

Technical field

The utility model relates to the body-building apparatus field, the structurally associated of concrete and a kind of back drawing type fitness equipment.

Background technology

Along with growth in the living standard, people pay attention to health all the more, and various body-building apparatus arise at the historic moment, for the working clans of sitting before office or table for computer; Bend over one's desk working owing to be seated for a long time, cause the discomfort of back, shoulder easily, and excess fat, hoard at belly and waist; Best mode to this improvement moves exactly, but for fear of the restriction in time, place, urbanite now; Best mode is in exactly and is taken exercises, however some fitness equipments of commonly seeing at present, in order to reach the training effect of health multi-section position; Its overall structure is all too huge and collection is difficult, and moulding shortcoming aesthetic feeling, and structure is complicated again.And some small-sized fitness equipments but are not directed to movement human back, shoulder on the market, and this case produces therefrom.

The utility model content

In view of this, the purpose of the utility model is to provide a kind of back drawing type fitness equipment to movement human back, shoulder.

For reaching above-mentioned purpose, the technical scheme of the utility model is:

A kind of back drawing type fitness equipment includes base, fork, handle, swing rotary components and damping unit, and fork is connected with base through the swing rotary components, and handle is located at the top of fork, is provided with damping unit between fork and base again.

This swing rotary components is made up of first adaptor, second adaptor and fixed cover, and fixed cover is fixed on the base, and the middle part of this fixed cover is provided with through hole; Said first adaptor has first pivot, and the below vertical axis direction of this first pivot extends a rotating shaft, and this rotating shaft is inserted in the through hole of fixed cover, and first adaptor can be rotated around fixed cover; Said second adaptor has second pivot, pivot joint first adaptor that this second adaptor can be swung, and the axial line of this first pivot axis line direction and second pivot is 90 ° after connecting.

Pivot joint second adaptor that said fork can be swung.

This base is provided with the vertical rod of a hollow, and this swing rotary components is located at the upper end of vertical rod, and at the front end of vertical rod seat cushion is installed.

Adopt said structure; The utility model is through handle pulling fork, and can make fork serves as the preceding moving swing of axle with second pivot, also can vacillate now to the left, now to the right for axle by first pivot; Rotating shaft that can also first adaptor is rotated for axle, reaches the purpose of tempering belly, back and waist muscle with this.

The specific embodiment

Below through specific embodiment and conjunction with figs. the utility model is elaborated.

As shown in Figure 1, the back drawing type fitness equipment of the utility model comprises base 1, fork 2, two handles 3, swing rotary components 4 and damping unit 5.

Base 1 by forward and backward

support

11,12 be connected forward and backward support medium-height trestle 13 and form, be provided with the vertical rod 14 of a hollow on this medium-height trestle 13 by the rear end, and seat cushion 15 be installed at the front end of vertical rod.

The top of fork 2 connects two handles 3; And make two handles 3 be about 90 ° setting with fork 2; The lower end of fork 2 is connected with the vertical rod 14 of base 1 through swing rotary components 4; This swing rotary components 4 is formed the upper end of being located at base vertical rod 14 by first adaptor 41, second adaptor 42 and fixed cover 43, and wherein the bottom 431 of this fixed cover 43 is stretched in the vertical rod 14 that is fixed on base and is limited in the block end 432 on fixed cover top, and the middle part of this fixed cover 432 is provided with through hole 433; Said first adaptor 41 has first pivot 411 in a tool pivot hole 412; The below vertical axis direction of this first pivot 411 extends a rotating shaft 413; This rotating shaft 413 is inserted in the through hole 433 of fixed cover; Make rotating shaft 413, through hole 433 be coaxial with vertical rod 14, making first adaptor 41 can also be simultaneously the axial line rotation of vertical rod 14 around fixed cover 43; Said second adaptor 42 has second pivot 421 in a tool pivot hole 422; The below of second pivot 421 is provided with joint chair 423; The installing hole that one connecting pin 6 passes joint chair 423 articulates first pivot 411; With this second adaptor 42 is located at the upper end of vertical rod 14 after first adaptor 41 connects, and the axial line of these first pivot, 411 direction of axis line and second pivot 421 is 90 ° after connecting; The bottom of said fork 2 is provided with a pivot seat 21 on the precalculated position; The connecting hole that one connecting pin 7 passes pivot seat 21 is connected with second pivot 421 of second adaptor; The fork 2 and second pivot 421 are formed articulate, the lower end of fork 2 is connected with damping unit 5 again, and the other end of this damping unit 5 then is connected on the base 1; This damping unit 5 can adopt spring or other adjustable damping structure; Can regulate the damping size according to exercise intensity, present embodiment adopts a kind of elastic rubber plate as damping unit, specifically not as limit.

During use, the user is sitting on the seat cushion 15, back to fork; With the hands hold handle 3 then; Both hands firmly draw forward, and belly and back firmly make fork 2 overcome the resistance of damping unit 5 simultaneously; Pulling fork 2 can second pivot 421 be moving swing (as shown in Figure 2) before the axle; Also can first pivot 411 vacillate now to the left, now to the right (as shown in Figure 3) for axle, rotating shaft 413 that can also first adaptor 41 be an axle rotation (as shown in Figure 4), reaches the purpose of exercise belly, back and waist muscle with these three kinds of motor patterns.
