A kind of sport barbell standTechnical field
The invention belongs to field of exercise equipment, are related to a kind of sport barbell stand.
Background technique
As people increasingly pay attention to healthy physical training, daily body-building is among people's life essential oneSubject, during body-building, barbell stand even more makes with the most use people.
But there is following defect during use: needing someone to help just to can be carried out forging on side when taking exerciseRefining, otherwise can generate danger, bring unnecessary trouble；One people's exercise effect is poor, and someone is needed to help to can be only achieved more preferablyExercise effect because take exercise when, lift it is motionless when, exercise effect is better, but if nobody existsIt helps on one side, risk is also to increase, and therefore, it is necessary to design a kind of sport barbell stand, so it is proposed that oneKind sport barbell stand, for solving the problems, such as above-mentioned propose.
Summary of the invention
In view of this, the present invention asks to solve to need someone to help just perform physical exercise on side when taking exerciseTopic, provides a kind of sport barbell stand.
In order to achieve the above objectives, the invention provides the following technical scheme:
A kind of sport barbell stand, including pedestal, the top two sides of the pedestal are respectively symmetrically fixedly mounted there are two firstColumn and two the second columns, and seat is fixedly installed at the top of pedestal, the seat is located between two the first columns, and twoA second column side close to each other slidably connects the same limit base, and connection is fixedly installed at the top of limit baseSeat offers mounting groove at the top of the attachment base, and is rotatably connected to take-up pulley in mounting groove, fixed on the take-up pulley aroundEquipped with the first drawstring, the same mounting plate, and two are fixedly connected at the top of two the first columns and two the second columnsThe bottom of mounting plate is respectively and fixedly provided with fixed pulley, and two the first column sides close to each other slidably connect the same lever, instituteIt states fixing sleeve on lever and is equipped with connector sleeve, one end of first drawstring extends through two fixed pulleys and the top with connector sleeveIt being fixedly connected, the side of the pedestal offers shifting chute, and movable plate is slidably connected in shifting chute, and the one of the movable plateSide extends to the outside of pedestal, and the top side of movable plate is fixedly installed with mounting post, and the top of the mounting post, which rotates, to be connectedIt is connected to pedal, the top side of the pedestal offers link slot, and link slot is located at the side of shifting chute, the shifting chuteThe through-hole being connected with link slot is offered on the inner wall of side, the other side of the movable plate is fixedly connected with the second drawstring, instituteThe one end for stating the second drawstring extends through through-hole and link slot and extends to the top of pedestal, one end of second drawstring and companyThe bottom of joint chair is fixedly connected.
The beneficial effect of this base case is: respectively lever can be moved using both hands or both feet, andIt can be effectively protected to people, the effect of exercise can be greatly increased.
Further, limit plate is slidably connected in the shifting chute, the side of the limit plate is fixedly installed with compression bulletSpring, one end of the compressed spring are fixedly connected with the side inner wall of shifting chute, second drawstring extend through limit plate andCompressed spring can buffer movable plate, so that movable plate will not collide with shifting chute.
Further, two the first column sides close to each other offer lifting groove, the top inner wall of the lifting grooveWith the same slide bar is fixedly connected in bottom interior wall, connecting plate is slidably connected on the slide bar, and two connecting plates are mutualClose side extends respectively to the outside of two the first columns and is fixedly connected respectively with the both ends of lever, carries out to leverWhen mobile, sliding limit can be carried out to lever.
Further, slide opening is offered on the side inner wall of the lifting groove, and the other side of connecting plate is fixedly installed with companyExtension bar, one end that two connecting rods are located remotely from each other extend respectively to the outside of two the first columns, and fixation is arranged in connecting rodThere are multiple discs, can according to need and increase a certain amount of load, to achieve the effect that body-building.
Further, it is arranged restraining position ring block on the slide bar, and stop collar is located at the lower section of connecting plate, the one of the stop collarThreaded rod is threaded on the inner wall of side, one end of the threaded rod, which runs through the other side inner wall of lifting groove and extends to first, standsThe outside of column, the other end of the threaded rod is rotatably connected to first clamping plate, and is fixedly mounted on the other side inner wall of stop collarThere is second clamping plate, the first clamping plate is in contact with slide bar with second clamping plate, can limit to stop collar, and utilize limitPosition ring is supported lever.
Further, it is rotatably connected to shaft on the side inner wall of the rotation slot, and is opened on the other side inner wall of rotation slotEquipped with rotation hole, one end of the shaft extends in rotation hole and is rotatablely connected with rotation hole, and the take-up pulley, which is set in, to be turnedIt is fixedly connected, the first drawstring can be stored on axis and with shaft, convenient for that lever can be carried out in mobile movable plateLifting.
Further, the shaft is equipped with rectangular chamber, and rectangular slab is slidably connected in rectangular chamber, and the one of rectangular slabSide is fixedly installed with connecting shaft, and one end of the connecting shaft is on the side inner wall of rectangular chamber and extends to the outer of attachment baseOne end of side, the connecting shaft is fixedly installed with turntable, when the first drawstring to be wound around on take-up pulley, is convenient for the first drawstringIt is wound around on take-up pulley.
Further, the side of the turntable is fixedly installed with spragging gear, and the side of attachment base is fixedly installed with brakingRing gear, the connecting shaft through braking ring gear, the spragging gear with braking ring gear activity engage, completion to the first drawstring intoWhen row storage, it can be convenient and take-up pulley is limited at any time.
The beneficial effects of the present invention are: height as needed first vertically moves lever, when lever is moved,Can connecting plate be moved, after height is suitable, move stop collar at this time, stop collar is moved to and connecting plateWhen bottom connection touches, threaded rod can be rotated at this time, drive first clamping plate to be moved, it can so that first clamping plate and secondClamping plate is clamped slide bar, limits to stop collar, may further be supported to lever, later successively can be by thick stickDisc is respectively sleeved in connecting rod, is then rotated driven by rotary disc shaft and is rotated, when shaft is rotated, can be drivenTake-up pulley is rotated, it can the second extra drawstring is wound around on take-up pulley, until by the second drawstring it is exceptionally straight, pusherDynamic driven by rotary disc spragging gear is moved, so that spragging gear is meshed with braking ring gear, can be carried out at this time to shaftLimit allows people to sit on the seat later, and foot steps down on pedal, can use both hands and pushes lever, or can use both feet and push awayDynamic pedal is moved, so that it may and it drives lever to be moved, carries out applied force simultaneously with both feet being just available with both hands,So that lever is moved, achieve the effect that trained.
Operation of the present invention is simple, is limited by stop collar to connecting plate, so as to be provided in people's trainingThe protection of effect, and then support staff can not needed and assisted, risk is greatly reduced, so that when people's body-building, it canTo greatly improve body-building effect.
