A kind of weight bench, including substrate 3, bed body 4 and two support meanss, the bed body positioned at two support meanss it
Between, the support meanss include bottom plate 1.1, top plate 1.2, sliding block 1.3 and balancing weight 1.5, are connected between the bottom plate and top plate
There are two the first guide pillars 1 being parallel to each other, the sliding block 1.3 is passed through by two the first guide pillars 1, and the top plate lower surface, which is fixed, to be connected
Two the second guide pillars 2 being parallel to each other are connected to, the balancing weight 1.5 is passed through by two the second guide pillars 2, the bottom of each second guide pillar
End is fixed with a block 2.1, a limited block 1.4 is fixed with each first guide pillar, two limited blocks 1.4 are located at the cunning
Below block, and two limited blocks are located at same level height, and the first compression spring 1.6 is connected between the top plate and sliding block,
The second compression spring 1.7 is connected between the balancing weight and the sliding block；The bed body includes supporting leg 4.1, the support
Leg and two bottom plates are both secured on the substrate 3；Connecting rod 5 is connected between two sliding blocks.It is cased with preventing in the connecting rod 5
Sliding sleeve 5.1.The top plate lower surface is fixed with cylindrical portion 1.2.1, and the upper surface of the sliding block is fixed with lower cylindrical portion
1.3.1.The axis collinear of the upper and lower cylindrical portion, and the external diameter of the lower cylindrical portion is less than the internal diameter of the upper cylindrical portion.Institute
When stating sliding block abutting limited block, first and second spring is in compressive state.Each support meanss have sliding block, one
Individual balancing weight, a top plate, a bottom plate, two the first guide pillars, two the second guide pillars, two limited blocks and two blocks；Institute
Supporting leg and the bottom plate is stated to be welded and fixed with the substrate.
As illustrated, trainer catches the upward weight lifting of Anti-slip cover, first and second compression spring is downwardly applied to reaction force, can
To play a part of similar Lifting barbell.If only designing a compression spring, the strength of starting needs of weight lifting can be caused too
It is small, it is very big with true weight lifting difference.Design two compression springs so that the power that the starting point of weight lifting needs is with regard to bigger, follow-up institute
The strength needed slowly increases, and is advantageous to train arm strength.And even if trainer is short of physical strength, Anti-slip cover is unclamped, sliding block can fall
To limited block, injury will not be produced to trainer.
In order to facilitate counting, in addition to touch-screen and controller, two support meanss are respectively the first support meanss and
Two support meanss；The top plate lower surface of first support meanss is provided with laser range sensor 10, and the laser ranging passes

The measured value of distance measuring sensor be less than given threshold number (although as shown in figure 3, now sliding block is picked up, balancing weight
Be not picked up also, weight lifting is simultaneously nonstandard), the display of standard weight lifting number numeral for start to train button be pressed after and
Terminate before training button is pressed, the number that the measured value of pressure sensor is zero is (as shown in figure 4, now not only sliding block is lifted
Rise, balancing weight is also picked up, weight lifting standard.)；When the measured value of laser range sensor is from the state more than or equal to given threshold
When changing into the state less than given threshold, it is designated as once；When the measured value of pressure sensor changes into zero from non-zero values,
It is designated as once.The given threshold is A-10cm；When the A is that the sliding block abuts the limited block, the laser ranging passes
The measured value of sensor.
Described to terminate after training button to be pressed, the display numeral of the weight lifting total degree and standard weight lifting number is
Zero.So end training button can be pressed so as to which numeral be reset after terminating to train.
The total degree of weight lifting and the number of standard weight lifting so can be intuitively shown, trainer is more beneficial for and grasps training
Effect.
