Description
Technical field
The invention belongs to quality testing field, more particularly, to a kind of baby walker impact strength test platform.
Background technology
With the increasingly raising of people's living standard, the quality and safety of infant article has obtained the weight of more and more people
Depending on, baby walker is a kind of widely used children education equipment, can help child's study walking, while to the standing of child and
Balanced capacity study is all very helpful, but due to the use of go-kart being child, while go-kart is continuous in use
Movement, this allows for go-kart may occur at any time to clash into.This requires that go-kart must have outstanding structure design
With the qualified strength of materials, realize, when child uses go-kart, in the face of the shock that may occur at any time, providing perfect to child
Protection.Under prior art conditions, baby walker can safely will according to standard GB/T 14749-2006 baby walker
Ask carries out crashworthiness test to baby walker, but in actual use, due to baby walker and its similar product
Species is various, and market in urgent need one kind can meet plurality of specifications baby walker striking experiment needs, while it is little to take up room, plus
Speed is apart from short and convenient to use impact strength test platform.
The content of the invention
In view of this, it is contemplated that proposing a kind of baby walker impact strength test platform, to realize meeting
Plurality of specifications baby walker striking experiment needs, while it is little to take up room, acceleration distance is short, and convenient to use hits
Hit intensity test platform.
To reach above-mentioned purpose, the technical scheme is that what is be achieved in that:
A kind of baby walker impact strength test platform, including platform cabinet 1, go-kart to be tested 2, power set and
Speed measuring device;
Go-kart to be tested 2 is horizontally set on the platform upper surface 12 of platform cabinet 1;Power set include counterweight 5 and
Pulley mechanism, counterweight 5 pull 2 impact platform cabinet of go-kart to be tested, 1 side wall, speed measuring device to be arranged on weight by pulley mechanism
Immediately below code 5, the horizontal range of go-kart to be tested 2 to 1 side wall of platform cabinet is equal to counterweight 5 to the perpendicular of speed measuring device speed measuring point
Straight distance.
It is to realize regulation test speed is accelerated under short distance that the design principle of the present invention is, power source adopts action potential
Principle (0.5* (the m of conversionCounterweight+mGo-kart)=mCounterweightgh,mCounterweightFor the weight of counterweight, mGo-kartFor the weight of go-kart, h is counterweight
Height of drop), allow counterweight freely falling body to drive tested baby walker to accelerate, go-kart can be allowed in short time short distance
Reach the speed of regulation;Acceleration distance is far smaller than that motor or cylinder accelerate;
Further, it is and few based on the frictional dissipation in action potential transfer process, can accurately by calculating counterweight
Height of drop obtaining final stroke speed, its deviation is in the range of standard is allowed.The experiment success rate of the present invention is high,
The velocity measurement mechanisms of equipment are used only to verify actual stroke speed in the range of standard is required, this is different from prior art
Motor or cylinder accelerate, velocity measurement mechanisms need in time monitoring control release power source.
In the practical application of the present embodiment, counterweight 5 pulls 2 impact platform cabinet of go-kart to be tested by pulley mechanism
1 side wall, go-kart to be tested 2 to 1 side wall of platform cabinet horizontal range be equal to counterweight 5 to speed measuring device speed measuring point it is vertical away from
