Abstract

The utility model belongs to the body -building apparatus field especially relates to a portable pectoralis major trainer. It is main including load device, grab handle connecting rod, grab handle, locating plate and braces. The load device passes through two ends of sheathed tube outer wall fixed connection at the locating plate, stretch out down planar axle fixed connection under the bearing in the one end of grab handle connecting rod and the load device, the other end of grab handle connecting rod sets up the grab handle perpendicularly, the locating plate is the hollow arc panel board of rectangle, is close to load device department at the locating plate concave surface and sets up the braces. User's both arms pass braces ring and fix the locating plate between two shoulders of front, and the right -hand man grips two grab handles respectively and does both arms to health both sides hard and expand the chest and move to the limit and do the short stay, and both arms are done the deformability and are got back to the exercise that initial position accomplished muscle group strength such as pectoralis major promptly hard afterwards.

Description

A kind of portable pectoralis major training devices

Technical field

This utility model belongs to exercise and fitness equipment field, a kind of portable pectoralis major training devices.

Background technology

The people having much inconvenience to go to gymnasium to take exercise likes at home or dormitory uses steel strand exerciser to temper breast Big flesh and arm strength, but the most easily occur that due to steel strand exerciser buccal skin, bullet are clamped in extension spring , there is potential safety hazard in the situations such as the spring of spring bullet comes to harm.

Summary of the invention

For above-mentioned existing problems, this utility model provides a kind of portable pectoralis major training devices, this training Device utilizes the load that the resilience force after overcoming spring to screw is taken exercise as pectoralis major, and load device is fixed on breast Before location-plate on and spring be arranged in sleeve pipe, eliminate the hidden danger that spring is hurted sb.'s feelings, use safety, function Stable.Training need can be met by installing different model spring generation different load in load device.

For solving above-mentioned technical problem, the technical scheme that this utility model provides is: a kind of portable pectoralis major Training devices, mainly includes load device, lever connecting rod, lever, location-plate and braces；Described load fills Put the outer wall by sleeve pipe and be fixedly connected on two terminations of location-plate, load device by axle, sleeve pipe, spring, End socket and bearing are constituted；Axle is placed in sleeve pipe, and the outside of axle is cased with spring, and one end of spring is solid in inserting axle Fixed connection, the other end inserts the fixing connection of internal surface of sleeve pipe, arranges the internal diameter diameter more than axle of spring, spring External diameter equal with the internal diameter of sleeve pipe so that have suitable space between spring and axle；Upper and lower two terminations of sleeve pipe Inner side arranges bearing, and axle connects through bearing inner ring is fixing；The upper end of axle and the upper plane of upper bearing (metal) are set Concordant, the lower end of axle stretches out the lower plane 1.5 of bearing～3.0 centimetres；Described end socket is arranged on the upper of sleeve pipe Termination；One end of described lever connecting rod is fixing with the axle stretching out lower bearing lower plane in load device to be connected, and holds The other end of handle connecting rod is vertically arranged lever；Described location-plate is rectangle hollow curved panel, and its material is relatively Light alloy material or rigid non-metallic material；At location-plate concave surface, the described back of the body is set at load device Band.

The parts of load device described in the utility model and composition are not belonging to content of the present utility model, use it Its load device is also possible；Described location-plate can be hollow can also be if that centre is provided with the Heavenly Stems and Earthly Branches The semi-hollow or solid of support girder；Described braces can be regular length can also be adjustable-length.

The beneficial effects of the utility model are:

1, training devices is fixed between the shoulder of front two by braces, and load device is fixed on the two of location-plate Individual termination, is arranged in sleeve pipe as the spring producing load, eliminates the hidden danger that spring is hurted sb.'s feelings, and uses peace Entirely, function-stable.

2, personalized instruction can be met by installing different model spring generation different load in load device The needs practiced.

3, this training devices is to strengthening the muscular force such as pectoralis major, pectoralis minor, biceps brachii m., anterior bundle of deltoid Measurer is of practical significance.
