Description

Simple combined adjustable chest-developer

The technical field is as follows:

the utility model relates to a simple combined adjustable chest expander.

Background art:

the chest developer is an appliance suitable for mass body building and exercising. The advantage of using a chest expander for exercise is that the biceps brachii muscle is a muscle with two muscle heads, and the main function is to bend the arm. In the case of flexion, an additional triceps brachii muscle is also used. However, the humerus muscle can be fully exercised only when some forearm lifting exercises are performed, such as the bending of the high-position chest developer or the bending of the reverse high-position chest developer. At present, common chest expander is bulky, weight is heavier, the purchase cost is higher, and moreover, some chest expanders single structure that have now can only carry out an action and train, when adopting ordinary extension spring chest expander to carry out the tensile training moreover, drops in the pulling handle of both hands chest expander, brings the injury of health to the person taking exercise very easily.

The invention content is as follows:

the utility model aims at providing a simple and easy adjustable chest expander of combination.

The above purpose is realized by the following technical scheme:

a simple combined adjustable chest expander comprises the following components: the adjustable pull plate comprises a supporting vertical plate, a bottom base plate and a top cross beam, wherein the bottom base plate is vertically connected with the supporting vertical plate, the top of the supporting vertical plate is vertically connected with the top cross beam, a group of upper lifting rings with the same structure are fixedly connected below the top cross beam, the upper lifting rings are connected with one ends of tension springs through spring buckles, the other ends of the tension springs are connected with lower lifting rings through tension springs, the lower lifting rings are fixedly connected with an adjustable pull plate, the adjustable pull plate is divided into a left adjustable pull plate and a right adjustable pull plate, two pull rings with the same structure are fixed below the adjustable pull plate, a pull rope is sleeved on each pull ring, one end of the pull rope is fixed through a hoop, and the other end of the pull rope is fixedly connected with a pull-down handle.

The adjustable chest expander of simple and easy combination, the left side of adjusting the arm-tie adjust the arm-tie and adjust the arm-tie on the right side and set up the jack that the diameter is the same respectively, and the jack interpolation has U type connecting piece, become an organic whole with the right side of adjusting the arm-tie through U type connecting piece with left side regulation arm-tie.

The adjustable chest expander of simple and easy combination, the top tiling of bottom backing plate have the yoga cushion.

The utility model has the advantages that:

1. the utility model adopts a lying type structure as a whole, when an exerciser needs to do tension training, firstly, the upper half of the body is laid on the yoga soft cushion on the bottom cushion plate, the legs are bent to place the shanks outside the bottom cushion plate, so that the chest of the exerciser is in line with the pull-down handle, the exerciser respectively holds the left adjusting pulling plate and the right adjusting pulling plate with both hands, because the tension spring is respectively connected with the upper hanging ring and the lower hanging ring through the spring fastener, the tension spring can rotate on the upper hanging ring and the lower hanging ring through the spring fastener, so that the exerciser can perform tension training at different angles, simultaneously according to exerciser's demand difference, can carry out tensile strength and adjust, reduce the quantity of adjusting the extension spring between arm-tie and the top crossbeam, adopt the snak link to connect between extension spring and the rings from top to bottom, can be fast convenient install and dismantle the extension spring, be suitable for and take exercise with different crowds.

The utility model discloses can make the training person carry out the synchronous strength training of both arms, insert the U connecting piece respectively in the jack of adjusting arm-tie and right side regulation arm-tie in a left side, then adjust the arm-tie and adjust the arm-tie in the right side through nut and U type connecting piece and make up integratively, the pull-down handle is held respectively to the training person, drive the pulling extension spring through adjusting the arm-tie, make the training person can carry out the synchronous strength training of both arms, when avoiding adjusting the arm-tie and adopting the components of a whole that can function independently, cause the uneven drawback of left side regulation arm-tie and right side regulation arm-tie atress when the pulling extension spring, can carry out the enhancement.

The utility model has the characteristics of simple structure, convenient operation, be convenient for remove, low in production cost etc, applicable in different crowds, adopt the formula structure of lying simultaneously, can effectually avoid the training person when pulling the drop-down handle, take place the handle and break away from the hand, can be rapid when the handle breaks away from will adjust the arm-tie and pull up through the pulling force of extension spring, adjust the arm-tie simultaneously and pull up the drop-down handle through the stay cord, prevent to cause the injury to training person's health.
