Detailed description of the invention
To be further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
The present embodiment facilitate adjustable chest-developer, as shown in Figure 1, 2, comprise 2, the two groups of extension springs 3 of two regulating arms, 1, two rocking arms and connecting box 4, the close end position of two described regulating arms 1 is hinged on the both sides on the top of described connecting box 4 respectively, and two described rocking arms 2 are hinged on the both sides of the bottom of described connecting box 4 respectively; Described regulating arm 1 is fixed in one end of described extension spring 3, and the other end is fixed on described rocking arm 2;
The one end and the described rotation external member 6 that are also provided with rotation external member 6 and two connectors, 5, two described connectors 5 are hinged, and the other end of connector 5 is articulated with the end of described regulating arm 1;
Further, as shown in Figure 3, described rotation external member 6 comprises revolving part 61; Described revolving part 61 comprises articulated section 611 and Access Division 612; Described articulated section 611 and two described connectors 5 are hinged, and described Access Division 612 is oval or rectangle, is convenient to lock described articulated section 611 on described adjustment slide opening 7.The housing of described connecting box 4 is provided with at least two and regulates slide opening 7, connection hollow out is provided with between two between described adjustment slide opening 7, described Access Division 612 is through described adjustment slide opening 7, and described Access Division 612 is moved in described adjustment slide opening 7 between two by described connection hollow out.Described adjustment slide opening 7 being set for connecting hollow out 7, described articulated section 61 being made to have the better free degree when sliding, avoiding occurring stuck phenomenon, and regulating required different positions more easily.
Further, described rotation external member 6 also comprises knob 62, and shown in institute Fig. 3, described knob 62 is provided with fixing threaded hole 8, described Access Division 612 is connected with described fixing threaded hole 8.Wear described fixing threaded hole 8 by screw described knob 6 is fixed on described Access Division.By rotating described knob 62, described revolving part 61 is moved up and down at described adjustment slide opening 7.
According to the needs of user self, rotate described knob 62, can when a circular hole moves to another circular hole in described adjustment slide opening 7 by described Access Division 612, thus drive described regulating arm 1 to move.When user thinks the dynamics regulating required chest-developer, again can rotate described knob 62, described Access Division 612 be fixed on described adjustment slide opening 7, no longer moves up and down, lock described rotation external member 6, the arm strength dynamics required for realization.The dynamics of chest-developer can be regulated by described rotation external member 6 simply and easily, the intensity of stretching can be selected according to each one different demand, the gradient of refinement adjustment dynamics, thus can be more humane, use chest-developer more easily.
Further, be also provided with locating part 9, described adjustment arm 1 is channel member, and described locating part 9 is arranged at the nearly upper end in the groove in described adjustment arm 1, and described locating part 9 is arranged between described connector 5 and described extension spring 3.When using chest-developer to allow two described rocking arms 2 come closer, not only can limit described connector 5 by locating part 9 no longer to continue to drive described regulating arm 1 relatively to draw close, thus keep relative distance between the described rocking arm 2 in left and right, and avoid interting described in extension spring group between extension spring 3, prevent described extension spring 3 from stirring together and being not easy to pull open again.
Further, described extension spring 3 is divided into two groups for being symmetrical arranged, and often group has two described extension springs 3 at least.The described extension spring of many groups is set, on the one hand, the object regulating pulling force and motion amplitude can be reached, on the other hand, the force requirements of different physique body builder can be met, to the better experience sense of user and train on.
Further, on described rocking arm 2, correspondence is fixed with handle 10.A not only comfortable but also anti-skidding hand can be provided to grab position to user by described handle 10, reduce the pain that in long-time use procedure, hand position occurs, add the use comfort of chest-developer.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
