Abstract
The utility model discloses a safety arm power device which mainly comprises a spring (1), and is characterized in that the safety arm power device also comprises two cranks (3) one ends of which are movably connected together; each crank (3) is connected with a connecting rod (4) through a pin (2); and the other ends of the two connecting rods (4 and 4') are respectively and movably connected with two ends of the spring (1). The safety arm power device has the advantages of simple structure; and when in use, the arms of a user do not need to be sheathed in a safety rope, therefore, the safety arm power device can effectively avoid various potential safety hazards. Simultaneously, the two cranks can also be stretched outwards, therefore, the safety arm power device can provide multiple modes for training arm muscle, thus being capable of overcoming the deficiency of relatively single function of the existing arm power devices.
Description
Technical field
The utility model relates to a kind of athletic equipment, specifically is meant a kind of safe chest-developer.
Background technology
Along with improving constantly of living standard, people also more and more pay attention to the raising of fitness, so chest-developer has just become people to temper one of the most frequently used utensil of arm muscle.At present chest-developer on the market in order to increase safety coefficient, on hand also is provided with safety rope two one or two all by two handles and be fixed on two high-strength springs between the handle and form.When people use, two safety ropes need be enclosed within respectively on hand, firmly bend the purpose that spring can realize taking exercise arm muscle then.Because after being enclosed within safety rope on the arm, just user's arm can be subjected to the restriction of chest-developer, when rebounding suddenly as spring in some cases, user's arm just can not be separated with chest-developer timely, therefore also there is the hidden danger of safety.
The utility model content
The purpose of this utility model is to overcome the defective that there is potential safety hazard in present chest-developer, provides a kind of simple in structure, can effectively overcome the safe chest-developer of various potential safety hazards.
The purpose of this utility model is achieved through the following technical solutions: safe chest-developer, mainly form by spring, simultaneously, this chest-developer also comprises the crank that two one ends are movably connected, and on each crank, all be connected with connecting rod, and the other end of two connecting rods is movably connected with the two ends of spring respectively also by pin.
In order better to realize the utility model, the profile of described two cranks is " S " type; And described connecting rod is positioned at the middle part of crank by pin.
Described two cranks link together by pin.
The two ends of described spring all are connected with connecting rod by pin.
The utility model is simple in structure, does not need in use arm sleeve in safety rope, therefore can have and effectively avoid various potential safety hazards.Simultaneously, because two cranks can also outwards stretch, therefore can provide the mode of multiple exercise arm muscle, thereby can also overcome the more single defective of present chest-developer function ratio.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1, the profile of two cranks 3 of the present utility model all is " S " type, and an end of these two cranks 3 links together by pin 2, all can rotate freely around pin 2 with the other end of guaranteeing two cranks 3.
Also be provided with a connecting rod 4 at the middle part of each crank 3, same, an end of these two connecting rods 4 also is fixed on the crank 3 by pin 2, can rotate freely around pin 2 to guarantee connecting rod 4.The other end of two connecting rods 4 then is connected the two ends of spring 1 respectively by pin 2.
When the operator firmly inwardly firmly moved crank 3, under the drive of connecting rod 4, spring 1 just can be crooked, thereby reach with the same function of common chest-developer; On the contrary, when the operator exerted oneself outside stretching crank 3,1 on this spring was stretched, and then can realize the function of common chest expander.
As mentioned above, just can realize the utility model preferably.
