Description

Starting door force measuring handle for single board skiing training

Technical Field

The invention relates to the technical field of sports equipment, in particular to a starting door force measuring handle for single-board skiing training.

Background

The starting gate is an important device for the skiing competition, comprises a timing system and a release device, can accurately record starting time and ensure that a player starts at the same time when necessary, the timing starting system also prompts the player through a signal lamp and countdown sound when controlling starting, and the player can push and pull the starting gate forcibly by utilizing upper limb strength during speed analogy competition, so that extra acceleration can be obtained. Therefore, how to exert force on the starting door is an important skill for speed skiing, and top athletes can strengthen training for the action. However, current skiing training analogue means structure is complicated, and the price is expensive, mostly skiing shank original place exercise, and similar treadmill is not strong to upper limbs training pertinence, is unfavorable for the practitioner to carry out upper limbs and holistic cooperation training to do not accurate its power state and power size when making the action.

Therefore, the starting door force measuring handle for the snowboarding training can detect the pulling force value of an athlete in real time and is convenient to analyze and record data.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a starting door force measuring handle for snowboarding training.

In order to achieve the purpose, the invention adopts the following technical scheme:

veneer skiing training is with starting dynamometry handle, including being used for the coupling assembling of being connected with starting the door, fixedly connected with fixed block on the coupling assembling, it draws pressure sensor to be provided with a plurality of groups between fixed block and the movable block, it contradicts with fixed block lateral wall and movable block lateral wall simultaneously to draw pressure sensor, the fixed block is equipped with the sleeve pipe with the movable block overcoat, the sleeve pipe with movable block fixed connection.

Further, coupling assembling includes two splint and bolt group, and two splint set up respectively in two relative lateral walls of the stand of starting door, and two splint pass through bolt group's connection, fixed connection in the stand of starting door.

Further, the fixed block tip with coupling assembling fixed connection, the fixed block with the surface that the movable block closes on each other is the plane for the pressure sensor is drawn in the installation, the tip fixed connection of movable block in on the sleeve pipe, the fixed block and the outer surface structure and the intraductal wall of sleeve pipe looks adaptation of movable block.

Furthermore, the end part of the fixed block is a cylinder, the end part of the movable block is a cylinder, and the radius of the end part of the movable block is larger than that of the end part of the fixed block.

Furthermore, the tension and pressure sensors are S-beam tension and pressure sensors, and the two groups of tension and pressure sensors are respectively arranged at two ends of the movable block plane structure.

Compared with the prior art, the invention has the beneficial effects that:

by the arrangement of the invention, the device capable of measuring the power-assisted pulling force of both hands of a sportsman in real time when the snowboarding starts in the snowboarding training is provided; the invention is based on the appearance of the existing starting door booster, carries out new design on the basis of not changing the appearance and hand feeling of the booster, integrates components such as a sensor, a control circuit and the like, is simple, convenient and reliable to install and operate and has high integration level; through the tension and pressure sensor, the handle has good force measurement consistency, the tension value of the athlete can be transmitted on line in real time, the analysis and the data recording are convenient, the analysis of the explosive force of the athlete, the time and the balance of both hands are convenient, and the method has very high guiding significance for the technical improvement of the athlete.
