Description
Technical field
The invention belongs to field of exercise equipment, and in particular to a kind of barbell protective device.
Background technology
Barbell is a kind of Excercise training apparatus, and equipment used in weight lifting, there is two kinds of standard barbell and non-standard barbell.Mark
Quasi- barbell is made of barbell bar (whippletree), disc and clip three parts.Non-standard barbell structure is same as standard barbell, and size will
Ask not stringent, making is of less demanding, and weight can be provided freely, and the stone barbell among the people used can also replace.
Widely used, either shoulder, back, arm, chest etc. the muscle of barbell, by barbell and different weight
Iron plate, with the muscular strength special training skill of more numbers, is cooked muscular endurance training for whole body muscle group, makes fat combustion, be converted into
Strong the line of beauty, improves movement but still flaccid muscles local for a long time；In addition, can more delay muscle aging, increase bone density,
Prevent osteoporosis and other effects.
, it is necessary to which barbell is elevated during barbell exercising, during this, since trainer is short of physical strength, often send out
Raw barbell falls the situation for injuring trainer by a crashing object.
The content of the invention
The invention is intended to provide a kind of barbell protective device, injure trainer by a crashing object to solve the problems, such as that barbell is fallen.
To solve the above-mentioned problems, the present invention provides following scheme：A kind of barbell protective device, including barbell and support
Frame, the barbell include barbell bar, disc and clip, are fixedly connected with traction rope in the barbell bar, on support frame as described above
Equipped with fixed pulley and anti-skid device, the traction rope is connected around fixed pulley with anti-skid device, and the anti-skid device includes block,
Through hole is equipped with block, movable block is slidably connected in through hole, the movable block is fixedly connected with traction rope, the lower end of movable block
Clump weight is connected with, the weight of clump weight is less than the weight of disc, and movable block is equipped with avoid holes, and the bottom of avoid holes is fixed
Connecting spring, spring are fixedly connected with limited block, and limited block is slidably connected with avoid holes, and limited block is along avoid holes central axes perpendicular
The upward cross sectional shape of Nogata is the combination of right-angled trapezium and rectangle, and rectangular edges side is connected with spring, right-angled trapezium
Base is overlapped with a side of rectangle, and the short side of right-angled trapezium is located remotely from the side of spring, and a high position for right-angled trapezium is in bevel edge
On, the block is equipped with the inclined-plane that guiding limited block slides, and block is equipped with the limit hole for being used for limited block insertion, described
Push rod is slidably connected in limit hole, the length of push rod is more than the length of limited block.
The operation principle and its advantage of this programme：In use, pulling push rod, the space of limit hole, trainer are reserved
Movement barbell, traction rope are in relaxed state, and movable block pulls traction rope under the gravity of clump weight, and movable block declines,
Limited block is under the action of block ramp, and extruding spring is entered in avoid holes, when limited block and limited block are located at same water
When on horizontal line, limited block is entered in limit hole in the effect of spring, accordingly even when trainer be short of physical strength it is powerless lift barbell,
Limited block is stuck in limited block, can not be moved upwards, so barbell can not also fall, be effectively prevent barbell and is fallen and injure training by a crashing object
The problem of person, when needing barbell to fall, promote push rod, push rod promotes limited block compression spring to enter in avoid holes, works as limit
After position block leaves limit hole, barbell can fall.
Further, the avoid holes and limit hole are equipped with multiple, and each limit hole is equal close to one end of limited block
The inclined-plane slided equipped with guiding limited block.Barbell can be limited in different height by, which so setting, falls.
Further, the avoid holes and limit hole are symmetrical arranged along the central axes of movable block.So increase is set to prevent
The resistance that barbell falls, and make the resistance balance, increase the service life of limit hole and limited block.
Further, multiple push rods are connected with one piece of push plate jointly, and the push plate is equipped with cylinder, the cylinder telecommunications
Number it is connected with the remote controler of its operation of control.So set and promote push rod whole limit holes is receded into avoid holes easy to quick
In.
Further, the traction rope is equipped with two and is connected to the both ends of barbell, and every traction rope is anti-with one
Sliding device is connected.So increase the balance of barbell.
Further, the barbell bar is equipped with anti-skid chequer.Being arranged so that prevents from skidding.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of barbell protective device of the present invention；
Fig. 2 is the structure diagram of anti-skid device in Fig. 1；
Fig. 3 is structure diagram when spring is compressed in Fig. 2.
Embodiment
Below by the further details of explanation of embodiment：
Reference numeral in Figure of description includes：Supporting rack 1, disc 2, barbell bar 3, traction rope 4, anti-skid device 5,
Block 501, push plate 502, push rod 503, cylinder 504, movable block 505, limited block 506, spring 507, fixed pulley 6.
Embodiment is basic as shown in attached drawing 1, Fig. 2 and Fig. 3：A kind of barbell protective device, including barbell and supporting rack 1, thick stick
Bell includes barbell bar 3, disc 2 and clip, and disc 2 is equipped with anti-skid chequer, two traction ropes are fixedly connected with barbell bar 3
4, supporting rack 1 is equipped with four fixed pulleys 6 and two anti-skid devices 5, and a traction rope 4 is anti-around two fixed pulleys 6 and one
