Description
Technical field
The invention belongs to field of exercise equipment, and in particular to a kind of barbell protective device.
Background technique
Barbell is equipment used in a kind of Excercise training apparatus and weight lifting, there is standard barbell and two kinds of 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 is wanted
Ask not stringent, production is of less demanding, and weight can be provided freely, and the civil stone barbell used also can replace.
Widely used, either shoulder, back, arm, chest etc. the muscle of barbell, by barbell and different weight
Iron plate is cooked muscular endurance training for whole body muscle group, makes fat combustion, be converted into repeatedly several muscular strength special training skills
Strong the line of beauty improves movement part but still flaccid muscles for a long time；In addition, can more delay muscle aging, increase bone density,
Prevent osteoporosis and other effects.
It during barbell exercising, needs to elevate on barbell, during this, since trainer is short of physical strength, often send out
Raw barbell falls the situation for injuring trainer by a crashing object.
Summary 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 connect around fixed pulley with anti-skid device, and the anti-skid device includes block,
It is equipped with through-hole in block, slidably connects movable block in through-hole, the movable block is fixedly connected with traction rope, the lower end of movable block
It is connected with clump weight, 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 where avoid holes central axes
Perpendicular on cross sectional shape be right-angled trapezium, and the side where its right angle waist is connect with spring, where oblique waist
Side is located remotely from the side of spring, and the block is equipped with the inclined-plane of guidance limited block sliding, and block is equipped with for limiting
The limit hole of block insertion, push rod is slidably connected in the limit hole, and the length of push rod is greater than the length of limited block.
The working principle of this programme and its utility model has the advantages that in use, pull push rod, reserve the space of limit hole, trainer
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 squeezes spring and enters in avoid holes, when limited block and limited block are located at same water under the action of block ramp
When on horizontal line, limited block enters in limit hole in the effect of spring, accordingly even when trainer is short of physical strength, inability lifts barbell,
Limited block is stuck in limited block, can not be moved upwards, so barbell can not also fall, effectively prevents barbell and fall to injure training by a crashing object
The problem of person, pushes push rod when needing barbell to fall, and push rod pushes limited block compressed 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
Inclined-plane equipped with guidance limited block sliding.Setting can limit barbell in different height and fall in this way.
Further, the avoid holes and limit hole are symmetrical arranged along the central axes of movable block.Setting increases and prevents in this way
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.Setting makes whole limit holes recede into avoid holes in this way convenient for quickly promotion push rod
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.Increase the balance of barbell in this way.
Further, the barbell bar is equipped with anti-skid chequer.Being arranged so that prevents from skidding.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of barbell protective device of the present invention；
Fig. 2 is the structural schematic diagram of anti-skid device in Fig. 1；
Fig. 3 is structural schematic diagram when spring is compressed in Fig. 2.
Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference in Figure of description include: support frame 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 support frame 1, thick stick
Bell includes barbell bar 3, disc 2 and clip, and disc 2 is equipped with anti-skid chequer, is fixedly connected with two traction ropes in barbell bar 3
4, it sets on support frame 1 there are four fixed pulley 6 and two anti-skid devices 5, a traction rope 4 is prevented around two fixed pulleys 6 with one
Sliding device 5 connects, and another traction rope 4 connect around other two fixed pulley 6 with another anti-skid device 5, and anti-skid device 5 wraps
Block 501 is included, through-hole is equipped in block 501, movable block 505 is slidably connected in through-hole, movable block 505 and traction rope 4 are fixed
Connection, the lower end of movable block 505 are connected with clump weight, and the weight of clump weight is less than the weight of disc 2, sets on movable block 505
There are four avoid holes, avoid holes run through movable block 505, slidably connect two pieces of symmetrical limited blocks in each avoid holes
506, a spring 507 is fixedly connected between two pieces of limited blocks 506, limited block 506 is vertical flat where avoid holes central axes
Cross sectional shape on face is right-angled trapezium, and avoid holes central axes are along the central axes of opening direction horizontal direction, avoid holes axis
Perpendicular where line that is to say the section of Fig. 2, and the side that two pieces of limited blocks 506 are connected with spring 507 is right-angled trapezium
Side where right angle waist, middle point symmetry of two pieces of limited blocks 506 relative to spring 507, block 501 are equipped with guidance limited block
The inclined-plane of 506 slidings, block 501 are equipped with the limit hole being embedded in for limited block 506, slidably connect push rod in limit hole
503, the length of push rod 503 is greater than the length of limited block 506, and limit hole is symmetrical arranged along the central axes of movable block 505, multiple
