Description

Chin-up exerciser

Technical field

A kind of chin-up exerciser is the utility model is related to, for hanging on horizontal bar or being drawn on similar fixture The upward exercise of body.

Background technology

Chin-up is the common methods for tempering arm strength, it is necessary to be carried out on horizontal bar.But have that the mortise lock of horizontal bar is seldom, i.e., Make have horizontal bar, for the not high people of stature, stretch out one's hand or takeoff and grab less than horizontal bar, very big inconvenience is caused to taking exercise；In addition, If can be rotated when taking exercise, not only increase the enjoyment of exercise, additionally it is possible to strengthen the adaptability of human body, but in horizontal bar Upper exercise chin-up does not have this function.

The content of the invention

The utility model aims to provide a kind of chin-up exerciser, not high for stature existing for prior art to solve People for, stretch out one's hand or takeoff and grab less than horizontal bar, to take exercise cause very big inconvenience；And the problem of without rotating function.

The technical solution of the utility model is：A kind of chin-up exerciser, it is characterised in that including hook, upper boom, under Bar, extension adjustment device and handle, hook are connected to the top of upper boom, and the lower end of upper boom passes through extension adjustment device and lower beam Upper end is connected, and the handle of both hands assurance is connected in the lower end of lower beam.

Described upper boom is tubular structure, and lower beam is screw rod；Described extension adjustment device is nut, the nut and upper boom Lower end rotation connection, the upper end of screw rod screws in the nut upwards.

Described nut and the rotation connection structure of upper boom lower end include upper lid, chassis, telophragma and two pressure bearings, Chassis is connected to the upper end of described nut, and telophragma is connected to the lower end of upper boom, and one is respectively equipped with the both sides up and down of telophragma Individual pressure bearing, pressure bearing below are located above chassis, and lid, Shang Gai and bottom are installed above superincumbent pressure bearing The edge of disk is fastened with bolt.

Non-slip rubber set is cased with described handle.

The utility model has the advantages that：The length of exerciser can be adjusted according to height, improves the convenience of exercise；Tool There is rotating function, not only increase the enjoyment of exercise, additionally it is possible to strengthen the adaptability of human body.
