Abstract

The utility model relates to an upper limb retractor for two persons. The retractor comprises a stand column, supporting columns and traction parts. The lower ends of the supporting columns are fixedly installed on the stand column and the upper ends of the supporting columns are fixedly connected with horizontal cross rods. Each traction part is composed of a traction rod, draglines and handles. The two ends of each traction rod are respectively connected with a dragline and the other end of the dragline is fixedly connected with each handle. The middle part of each traction rod is fixed on each horizontal cross rod and the traction rod is movably matched with the horizontal cross rod in the axial direction. The traction rods are in reverse U-shaped structure. The distance between the traction rods at the two sides of the stand column is equal to the distance of the two ends of each traction rod. Two practicers can respectively hold on to the two handles of same traction rod and conduct self-practice, and also can hold on to the two handles at the same side of the two traction rod and conduct interaction practice. The upper limb retractor for two persons has the advantages of being interesting, capable of promoting communication of users and applicable to amusement and fitness equipments in outdoors public places such as residential quarters, plazas and parks.

Description

A kind of double arm extension apparatus

Technical field

The utility model relates to a kind of body-building apparatus, specifically about a kind of arm extension apparatus.The utility model is applicable to the body-building apparatus of the outdoor public sites such as residential quarter, square, park.

Background technology

Arm extension apparatus is comprised of column, pillar and tractor, and the traction piece of existing double arm extension apparatus generally all is relatively independent existence, and two people can only the oneself practise, and can not experience the power that the other side applies, and lack communicating with each other between interest and the practitioner.

Summary of the invention

The purpose of this utility model is the shortcoming that exists for prior art, provides a kind of two practitioners can mutually experience the motoricity that the other side applies, interesting strong, the double arm extension apparatus that promotes communication exchange between the user.

The technical solution of the utility model comprises column, pillar, traction piece, the pillar lower end is fixedly mounted on the column, the pillar upper end is fixedly connected with horizontal cross bar, traction piece is comprised of draw bar, drag-line and handle, the two ends of draw bar connect respectively drag-line, the other end of drag-line is fixedly connected with handle, be installed on the horizontal cross bar in the middle of the draw bar, between draw bar and the horizontal cross bar radially movingly, mainly be that draw bar is inverted U-shaped, the distance between the draw bar of column both sides equates with distance between the drag-line of draw bar two ends.

In above technical scheme, fixedly mount stop on the pillar at place, draw bar U-shaped centre position, this stop is comprised of gag lever post and connecting rod, and connecting rod one end is fixed in the middle of the gag lever post, and the other end is fixed on the pillar.

The beneficial effects of the utility model are that the distance between the draw bar of column both sides equates with distance between the draw bar two ends, two handles that two practitioners can hold on the same draw bar separately carry out oneself's exercise, also can hold on two draw bars two handles of homonymy and carry out the interaction exercise, have interesting strong, promote between the user advantage such as communication exchange.

Description of drawings

Fig. 1 is perspective view of the present utility model.

The specific embodiment

Double arm extension apparatus as shown in Figure 1, comprise column 2, pillar 4, traction piece 1, pillar 4 lower ends are fixedly mounted on the column 2, pillar 4 upper ends are fixedly connected with horizontal cross bar 5, traction piece 1 is by draw bar, drag-line and handle form, the two ends of draw bar connect respectively drag-line, the other end of drag-line is fixedly connected with handle, be installed on the horizontal cross bar 5 in the middle of the draw bar, between draw bar and the horizontal cross bar 5 radially movingly, draw bar can rotate at horizontal cross bar 5, but axial restraint connects, and draw bar is inverted U-shaped, and drag-line and handle are connected to two bottoms of inverted U-shaped draw bar, distance between the column 2 both sides draw bars equates with distance between the drag-line of draw bar two ends, the distance between the draw bar two ends according to general human body about distance design between two hands.Two users can occupy separately a traction piece 1 pulling traction piece 1 and carry out independent exercise, carry out the interaction exercise one side also can respectively account for the traction piece 1 that spurs of two traction pieces 1.

Pillar 4 fixed installation stops 3 at place, draw bar U-shaped centre position, this stop 3 is comprised of gag lever post and connecting rod, connecting rod one end is fixed in the middle of the gag lever post, and the other end is fixed on the pillar 4, and the length of gag lever post designs according to the pendulum angle needs of draw bar.

Column 2 is shaped with four clamp bar slots of vertical direction, and the lower end of pillar 4 and middle part are fixedly mounted in the draw-in groove of column 2 by cross bar 6, draw-in groove bar 7 respectively.Pillar 4 lower ends are connected the knuckle place with cross bar 6 and are provided with rubber protecting jacket, avoid knuckle scratch human body.
