The present invention relates to a kind of have a safety guard be used for developing the required specific strength training equipment of weight lifting.
The at present domestic and international general equipment that carries out strength building, though various in style, with regard to its performance, only limit in order to develop general strength building.Still lack the specialized training equipment that can be used for developing the required separately specific strength of each sports events.Thereby the development of specific strength and raising be restricted, and also affects the raising of each project sports achievement to a certain extent.
Weightlifting is a kind of motion that typically overcomes gravity acting.Therefore, say in a sense that the raising of weightlifter's specific strength just means the raising of weightlifting achievement, this point is because the movement characteristic of itself determines.Exactly because Sports Practice confirms to lack the development specific strength, particularly lack the specialized training equipment that has the security protection device, so carrying out weight training exercises, particularly carrying out being easy to take place injured accident in large amount of exercise, the excess load training.And the sportsman is in a single day injured, because of the possibility that is limited to the medical condition recovery from illness is very little, has both made healing, also must take the suitable time, shortens sport life span.Certainly weight person then may be disabled, and has forfeited motion life." there is decision consciousness ", just because of weight lifting is injured easily, so also cause the sportsman to produce the mental handicape of " being afraid of to hinder " easily.Influence when training conversely and the generation of mental handicape is inevitable, the increase of amount and the raising of matter, everything all affects the weightlifting achievement, and the raising of particularly big weight classes weight lifting achievement is so press for a kind of specialized training equipment that develops the weight lifting specific strength safely.
Task of the present invention will provide a kind of exactly and both can prevent the athletic injury accident again effectively, guarantee the specialized training equipment of training athlete safety in conjunction with weight lifting specific technique, development specific strength.
Task of the present invention realizes as follows:
Know according to the weightlifting know-why: the curve movement of weightlifting is a kind of curve movement that is serpentine.So the main body of this training aids is with bar and some guider combinations, bar is finished the comprehensive rigidity combination of multidirectional motion under the qualification of guider and positioner.So curvilinear motion that the bar motion can be synthesized the serpentine of various different curvature when weight lifting.And this curve meets the peculiar strength curve of weightlifting.Therefore, be fit to very much development weight lifting specific strength.Certainly also can develop other project foundation strength well.
Simultaneously, this training aids also utilizes hydraulic principle, can be according to the actual needs of training, control whole erector＜comprise bar, disc (or heavy burden sheet) by the way of utilizing throttling and cut-off equipment control fluid flow〉decrease speed and the height of decline, guarantee the training athlete purpose of safety thereby reach, also can prevent the noise that runs foul of each other and produce because of disc simultaneously effectively.
The invention is further described below with reference to accompanying drawing:
Fig. 1 is a side view of the present invention;
Fig. 2 is a front view of the present invention;
Fig. 3 is the vertical view that the present invention left side holder amplifies.
With reference to accompanying drawing:
Two parallel to each other and its upper surfaces respectively are fixed with the holder (3) of two vertically-guided pipes (4) and an oil cylinder (6).Holder (3) is fixed on ground or other platform with foundation bolt (1).The inner chamber of holder (3) be one "
" passage of shape intercommunication.The top of middle vertical passage communicates with oil cylinder (6), and the vertical passage of both sides communicates with vertically-guided pipe (4), in interconnection and middle vertical passage intersection, two relative and opposite one-way cocks (5) of direction is arranged respectively.One ram cylinder (12) is arranged in the oil cylinder (6), and the two is by " O " RunddichtringO (8), rubber blanket (13) and oil cylinder cover (10) sealing.Piston (26) is housed in the ram cylinder (12), and the two is by " O " RunddichtringO (14), rubber cushion (16) and oil cylinder cover (18) sealing.
Between per two vertical conductive pipe (4), a coaster that can be in vertical motion (32) is all arranged, should by pulley (34) be connected with vertical conductive pipe (4) and roll the cooperation.There is an alignment pin (29) coaster (32) upper end, and the lower end of coaster (32) is connected with piston (26), coaster (32) centre have a level to slideway (25) and the slide block (30) that is slidingly matched with it.The centre of slide block (30) has a pilot hole, in order to bar (27) to be installed and bar (27) is rotated around its transverse axis.In vertical conductive pipe (4) outside two heavy burden sheet guide rails (9) parallel to each other are installed respectively, its lower end and holder (3) outer is fixed, the middle heavy burden sheet (22) of installing, and upper end and upper junction plate (33) are fixing.Heavy burden sheet (22) is connected by connecting rod (20) according to the heavy burden needs.The lower end of steel wire rope (24) is connected with connecting rod (20), and the upper end is connected with bar (27) by adapter sleeve (28).
The medial surface of holder (3) middle part has one to be connected with oil exit pipe (37) with outage (7) that middle vertical passage communicates.On the pipeline of oil exit pipe (37), be in series with an adjustable flow control valve (38) and a magnetic valve (39) in order to dam.Oil-out at shutoff valve (39) is connected with oil return pipe (40), and oil return pipe (40) spill port (2) forward and backward with being positioned at holder (3) links to each other, and forms the circulating oil path of a closure.
Before the operation, earlier erector is placed extreme lower position, in oil filler point (36) conductive pipe (4) pipe, fill with hydraulic oil.Adjust disc (41) or heavy burden sheet (22) weight as required, regulate the flow velocity of choke valve (38), and optoelectronic switch (21) is adjusted to gives take the altitude by adjust regulating turn-knob (11) (17), lift adjustment cover (15) and lifting regulating rod (19), and the connection power supply, make optoelectronic switch (21) and magnetic valve (39) enter duty.
Carry when lifting on the bell when training, because human body acts on the variation of the power of bar (27), make bar (27) drive coaster (32) and doing vertical ascending motion simultaneously, drive also that slide block (30) is done forward to some extent, horizontal movement backward in slideway (25), and bar (27) self is done the rotation around transverse axis.At this moment the motion of bar (27) in fact synthesizes a kind of curvilinear motion that is serpentine.And this curve meets the peculiar strength curve of weightlifting, so just can develop the required specific strength of weight lifting well by this exercising machine.In last act acting, coaster (32) drives piston (26) and ram cylinder (12) moves upward, make oil cylinder (6) produce certain negative pressure, also because the pressure of liquid itself is opened one-way cock (5), oil just is drawn into oil cylinder (6) and ram cylinder (12) simultaneously.Work as release this moment, because pressing down piston (26), the gravity effect make oil cylinder (6) produce certain pressure, one-way cock this moment (5) is closed, oil just enters choke valve (38) from oil drain out (7) through oil exit pipe (37), enters in the conduit (4) from oil return opening (2) through oil return pipe (40) by controlled oil control＜this moment of choke valve (38) to flow〉thus the decrease speed of erector controlled.When erector drops to when giving take the altitude, anti-dazzling screen (23) on the coaster (32) just shelters from the light of optoelectronic switch (21), magnetic valve this moment (39) cuts out, oil circuit is blocked, and erector just stops to descend, and is positioned at and gives on the take the altitude, thereby can play and guarantee athletic training of safety, prevent the generation of athletic injury accident effectively, also fundamentally eliminate the noise that disc collides and produced simultaneously, created good training environment, be of value to athletic health.
