Description
Technical field
The utility model relates to a kind of counterweight, particularly a kind of hydraulic pressure counterweight for body-building apparatus.
Background technology
The development of China's body-building apparatus industry starts from late 1980s, along with the success of China's entry into the WTO and Beijing Olympics Bidding, for the development of body-building apparatus industry provides advantage and opportunity to develop, the body-building apparatus manufacturer that constantly expands as of body-building troop brings dense business opportunity.The conventional professional equipment chamber combined training machine in gymnasium is again multifunctional trainer at present, aims at vigorous and graceful fan and professional athlete design.Its advantage is the general strengthening exercise that can carry out 10 to 50 various motions, its core component is load device (resistance gauge), the counterweight system that it is made up of multiple tune weights groups, but because existing counterweight system can produce larger collision noise when the lifting, and be to adjust the gravity of weights group due to counterweight system utilization, therefore in tune weights group dropping process, can produce accelerated motion, person taking exercise is as absent minded or strength is not enough, can be subject to the injury of the restoring force of apparatus, increase and tempered injured possibility.
Utility model content
The purpose of this utility model is, a kind of hydraulic pressure counterweight for body-building apparatus is provided.It can provide an even adjustable damping force for taking exercise, and in motion process, is difficult for producing noise.
The technical solution of the utility model: for the hydraulic pressure counterweight of body-building apparatus, be characterized in: comprise the liquid storing barrel of band bottom mounting flange and the piston cylinder of band bottom mounting flange; Between described liquid storing barrel and piston cylinder, be connected with relief pipeline by connecting pipe, connecting pipe is positioned at the bottom of liquid storing barrel and piston cylinder, relief pipeline is positioned at the middle part of liquid storing barrel and piston cylinder, described connecting pipe is provided with flow control valve, relief pipeline is provided with check (non-return) valve, and the permission liquid flow direction of described check (non-return) valve is the direction that piston cylinder points to liquid storing barrel; In described piston cylinder, be provided with piston and piston rod, piston cylinder top is connected with cylinder cap by flange, and described cylinder cap center offers pilot hole, and piston rod is located in pilot hole.
The above-mentioned hydraulic pressure counterweight for body-building apparatus, is provided with spacing ring in described piston cylinder, and the height of spacing ring is positioned on relief pipeline.
The aforesaid hydraulic pressure counterweight for body-building apparatus, is fixed with reset briquetting on described piston, utilize the gravity of reset briquetting to make piston reset.
The aforesaid hydraulic pressure counterweight for body-building apparatus: described liquid storing barrel top is provided with filling opening.
Compared with prior art, the utility model adopts the mode of piston cylinder pumping liquid to build a damping system, and piston, in the process of moving up and down, is not easy to produce noise, and it is very even to lift the resistance that piston makes, thereby can improve training effect.And piston of the present utility model replys the gravity that only relies on reset briquetting, and also have the damping support of liquid in piston cylinder, therefore restoring force is little and even, is difficult for causing athletic injury.The utility model can utilize the Flow-rate adjustment of flow control valve on connecting pipe to realize the size of piston damping power.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.For the hydraulic pressure counterweight of body-building apparatus, as shown in Figure 1, comprise the liquid storing barrel 1 of band bottom mounting flange and the piston cylinder 2 of band bottom mounting flange; Between described liquid storing barrel 1 and piston cylinder 2, be connected with relief pipeline 10 by connecting pipe 9, connecting pipe 9 is positioned at the bottom of liquid storing barrel 1 and piston cylinder 2, relief pipeline 10 is positioned at the middle part of liquid storing barrel 1 and piston cylinder 2, described connecting pipe 9 is provided with flow control valve 11, relief pipeline 10 is provided with check (non-return) valve 12, and the permission liquid flow direction of described check (non-return) valve 12 is the direction that piston cylinder 2 points to liquid storing barrel 1; In described piston cylinder 2, be provided with piston 5 and piston rod 6, piston cylinder 2 tops are connected with cylinder cap 4 by flange 3, and described cylinder cap 4 centers offer pilot hole, and piston rod 2 is located in pilot hole.In described piston cylinder 2, be provided with spacing ring 8, the height of spacing ring 8 is positioned on relief pipeline 10.On described piston 5, be fixed with reset briquetting 7.
Hydraulic pressure counterweight for body-building apparatus according to claim 1, is characterized in that: described liquid storing barrel 1 top is provided with filling opening 13.
Operation principle of the present utility model: before use, need be in liquid storing barrel filling liquid, liquid level should be higher than relief pipeline, while upwards lifting piston, hydraulic cylinder by connecting pipe 9 by liquid suction piston cylinder; Now, the flow of connecting pipe directly determines the damping force that piston is received, therefore can realize by adjust flux control valve.When after the lifting stroke and finish of piston, due to the deadweight of reset briquetting, piston will fall automatically, and now liquid also can return to liquid storing barrel along relief pipeline.Under the check (non-return) valve effect of relief pipeline, when piston ascending motion, only has entrance of connecting pipe, and when piston descending motion, there are two outlets, so damping is large while lifting, when reply, restoring force (the comprehensive function power of the damping that the deadweight of reset briquetting and piston are subject to) is less.
