Description

Multifunctional chest developer

Technical Field

The utility model relates to a body-building apparatus field specifically is a multi-functional chest expander.

Background

The chest developer is an apparatus suitable for public body-building exercises, and has various types, such as spring chest developer, rubber strip chest developer and the like. The chest expander generally comprises a handle and an elastic rope, wherein two ends of the elastic rope are respectively and fixedly connected with the handle. When the chest expander is used, two handles are generally held by two hands, the elastic rope is pulled open by utilizing the strength of arms, and the effect of exercising arm muscles is further achieved.

However, the conventional chest expander can only perform chest expansion training, but cannot perform waist and abdomen tension training and leg tension training, so that the conventional chest expander still needs to be improved in multi-part training function.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a realize many parts training function, provide a multi-functional chest expander.

The utility model provides a, a multifunctional chest expander, including a plurality of groups spring, first handle and second handle, the both ends difference fixed connection of spring is in on first handle and the second handle, still include two running-boards, a plurality of groups stretch cord and a pair of handle, two running-boards movable mounting respectively are in on the first handle, a plurality of groups stretch cord both ends respectively with the second handle with a pair of handle swing joint.

Furthermore, the pedal plate is provided with a fixing hole, and the rigid rope passes through the fixing hole and is buckled into the first handle through the locking connecting piece.

Furthermore, the pair of handles is formed by connecting the two handles together through a connecting rod, and an elastic rope penetrates through the connecting rod.

Further, a safety rope is arranged between the first handle and the second handle, and the length of the safety rope is smaller than the maximum extension of the spring.

Furthermore, a safety rope is arranged between the second handle and the pair of handles, and the length of the safety rope is smaller than the maximum extension of the elastic rope.

Has the advantages that:

above technical scheme makes the utility model discloses outside having chest extension pulling force training's function, can also utilize the running-board with a pair of handle is through reciprocal pulling the stretch cord plays the effect of training waist, abdomen, shoulder, shank muscle.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1-a spring, 2-a first handle, 3-a second handle, 4-a pedal, 5-a plurality of groups of elastic ropes, 6-a pair of handles, 7-a fixing hole, 8-a rigid rope, 9-a locking connecting piece, 10-a connecting rod and 11-a safety rope.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work all belong to the protection scope of the present invention.

As shown in fig. 1, the multifunctional chest expander comprises a plurality of groups of springs 1, a first handle 2 and a second handle 3, wherein two ends of each spring 1 are respectively and fixedly connected to the first handle 2 and the second handle 3, the multifunctional chest expander further comprises two foot plates 4, a plurality of groups of elastic ropes 5 and a pair of handles 6, the two foot plates 4 are respectively and movably installed on the first handle 2, and two ends of the plurality of groups of elastic ropes 5 are respectively and movably connected with the second handle 3 and the pair of handles 6. When in use, in the first condition, the first handle 2 and the second handle 3 are directly used for chest expanding training; in the second situation, the pedal plates 4 can be arranged on the first handle 2, the pair of handles 6 are connected to the second handle 3 through the elastic ropes 5, when in training, in a sitting and lying state, two feet step on the two pedal plates 4 to fix, two hands hold the pair of handles 6, and the elastic ropes 5 are pulled back and forth to train the waist and abdomen; in the third situation, different from the second situation, in the standing state, two feet step on two pedals 4 to fix, two hands hold a pair of handles 6, and the handles are pulled upwards to reduce the height and pull a plurality of elastic ropes 5 to carry out shoulder-elbow joint and muscle training; in the fourth case, unlike the second case, a stack of handles 6 of the hand is fixed, and joints and muscles of the leg are exercised by straightening the leg by reciprocating bending and pulling a plurality of elastic cords 5. The four training modes play a role in training joints or muscles of waist, abdomen, shoulders and legs. Is very convenient and has comprehensive functions.

The pedal is provided with a fixing hole 7, and a rigid rope 8 passes through the fixing hole 7 and is buckled into the first handle 2 through a locking connecting piece 9. This kind of structure for running-board 4 is more firm, tramples more conveniently, improves training efficiency, promotes to use and experiences.

Preferably, the pair of handles 6 is formed by connecting two handles together through a connecting rod 10, and the elastic rope 5 is threaded on the connecting rod 10.

A safety rope 11 is further arranged between the first handle 2 and the second handle 3, and the length of the safety rope 11 is smaller than the maximum extension of the spring.

A safety rope 11 is further arranged between the second handle 3 and the pair of handles 6, and the length of the safety rope 11 is smaller than the maximum extension of the elastic rope 5.

The scheme is mainly optimized and improved in the aspect of safety, the safety rope has two functions, and firstly, when the elastic ropes 5 and the springs 1 are tightened off, a trainer cannot hurt muscles; secondly, prevent that the trainer from dragging the power too much to exceed the limit of stretch cord 5 and spring 1, can avoid aggravating the tensioner load and shorten its live time.

The embodiment of the utility model provides a it is difficult to see out, outside having the function of chest extension pulling force training, can also utilize the running-board 4 with a pair of handle 2 through reciprocal pulling the stretch cord plays the effect of training waist, abdomen, shoulder, shank muscle, and the safety when optimization scheme can also provide better experience and guarantee training.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and these embodiments are intended to be encompassed by the scope of the invention.
