Description
Technical field
The utility model belongs to field of exercise equipment, and in particular to it is a kind of using high frequency lasers rangefinder check weighing, test the speed
Force exerciser.
Background technology
Force exerciser used at present generally connects counterweight to carry out strength building using drawstring around pulley blocks, matches
Weight, group number, speed are the parameters of strength building key, and traditional force exerciser can not acquire these parameters, strength is caused to instruct
White silk is ineffective, and in order to solve this problem, those skilled in the art increase various parameters on force exerciser
Harvester, but current parameter acquisition devices mostly there is complicated, of high cost, gathered data it is inaccurate lack
Fall into, such as installation weighing sensor acquisition counterweight parameter in the force exerciser that has, due to counterweight using when will produce impact, make
Inaccurate at weighing sensor gathered data, weighing sensor is fragile, while user only can just know after pulling counterweight
The total weight of road itself selection.
Utility model content
Utility model aims to solve the parameter acquisition devices of prior art force exerciser there are it is complicated,
Defect of high cost, gathered data is inaccurate, provide it is a kind of using high frequency lasers rangefinder check weighing, the force exerciser that tests the speed,
Its method for using laser ranging acquires counterweight, the velocity information of group number, drawstring, is not influenced by counterweight impact, gathered data
Accurately.
The utility model is achieved by the following technical solution:
It is i.e. a kind of using high frequency lasers rangefinder check weighing, the force exerciser that tests the speed, including portal frame and weight stack, gantry
Frame is equipped with pulley blocks, and drawstring connect around pulley blocks with weight stack bolt, and weight stack is all provided on each weight stack equipped with multiple
There is pin hole, it is characterised in that portal frame is equipped with high frequency time laser range finder, and high frequency time laser range finder is located at the upper of weight stack
Side or lower section, Laser emission are rectified on the outside of the front end of pin hole or rear end.
The pin hole position of each weight stack of the utility model is identical, i.e., multiple pin hole vertical arrays are straight at one
Line, when weight stack bolt is inserted into pin hole, handle and/or front end can be exposed outside pin hole, and high frequency time laser range finder can be examined
Handle or the front end pin dew part for measuring weight stack bolt, by measuring the distance between counterweight pin, so that it may to calculate counterweight
Group number, and then obtain the data of counterweight.
Using the utility model, user is not necessarily to just can know that the total weight itself selected after pulling counterweight.
The high frequency time laser range finder of the utility model is prior art commercial product, can send out swashing for high frequency time
Light can not only measure the distance between weight stack bolt (static state), calculate the group number of weight stack, and then obtain counterweight
The data of sheet weight can also detect the distance change of weight stack bolt (dynamic), calculate the acceleration of weight stack movement, into
And the speed of drawstring can be calculated.
This programme is only with 1 high frequency time laser range finder, so that it may to acquire the speed letter of counterweight, group number, drawstring simultaneously
Breath does not use contact type measurement, and the position of high frequency time laser range finder can flexibly install, and is not influenced by weight stack impact,
Measurement result is accurate.
The high frequency time laser range finder of the utility model is the commercial product of prior art maturation, can be with the prior art
The microcontroller or processor signal of force exerciser connect, and the data of acquisition are shown on a display screen.
The utility model has the advantages that reasonable for structure, easy to use, measurement result is accurate, with long service life.

Specific implementation mode
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows:The top of portal frame 2 be equipped with pulley blocks 3, drawstring 4 bypass pulley blocks 3 after with weight stack
Bolt 10 connects, and when weight stack bolt 10 is inserted into weight stack, front end can expose a part, high frequency time laser from 8 front end of pin hole
Rangefinder 1 is mounted on the top of portal frame 2, and Laser emission end is downward, face pin hole, i.e. 10 exposed division of face weight stack bolt
Point.
When the utility model is used, high frequency time laser range finder 1 and acquisition module or directly with the control of force exerciser
Device connection processed carries out data acquisition, and the Laser emission of high frequency time laser range finder 1 rectifies 8 front end of pin hole to weight stack 7, when
When weight stack bolt 10 is inserted into the pin hole 8 of weight stack 7,10 front end of weight stack bolt can stretch out pin hole 8, acquisition module or controller
Instruction is sent out to high frequency time laser range finder 1 according to cycle T, high frequency time laser range finder 1 can detect weight stack bolt 10
Elevation information, while this information is passed into controller, controller is converted into group number, the weight data of weight stack, makes every
One user is very clear to the counterweight currently selected at the first time, without just showing weight after pulling counterweight.Work as use
When person pulls weight stack, high frequency time laser range finder 1 can detect the height change of weight stack 7, be become using the height detected
Change and calculates the speed that weight stack 7 moves to get the speed of drawstring 6 is gone out.
The utility model is not limited to above example, as the position of laser range finder can also be arranged under weight stack
Side, Laser emission end can also be directed toward the handle of weight stack bolt.
