Embodiment
For making those skilled in the art understand the technical solution of the utility model better, the utility model fall-down test device is described in further detail below in conjunction with the drawings and specific embodiments.
In the utility model, this fall-down test device comprise bracing frame 7, forked lift platform 4, base plate 6 and before sales kit (SK) 5 falls, be arranged at sales kit (SK) 5 wait to fall baffle plate 1 under the angle, this test unit also includes baffle plate and withdraws mechanism, described baffle plate is withdrawn mechanism and is connected with baffle plate 6, and baffle plate is withdrawn mechanism can make baffle plate 1 waiting to fall under the angle and remove from sales kit (SK) in sales kit (SK) 5 processes.
Embodiment 1:
As shown in Figure 1, in the present embodiment, described baffle plate is withdrawn mechanism and is comprised that hawser 3 and rope are around mechanism, one end of described hawser 3 is fixed on the bracing frame 7, its other end is walked around rope and is connected with baffle plate 6 around mechanism, described rope is connected the forked root of lifting platform 4 around mechanism, hawser 3 one section placement vertically between mechanism at bracing frame 7 and rope, and hawser 3 is placed at one section along continuous straight runs of rope between mechanism and baffle plate 1.
In the present embodiment, described rope includes pulley 2 around mechanism, and hawser 3 is walked around from pulley 2, and the axle of pulley 2 is connected the forked root of lifting platform 4, the one section vertically placement of hawser 3 between bracing frame 7 and pulley 2, the one section along continuous straight runs of hawser 3 between pulley 2 and baffle plate 1 placed.
In the present embodiment, an end of hawser 3 is fixed on the top of bracing frame 7, and the other end of hawser 3 is walked around pulley 2 backs and is connected with baffle plate 1.
Wherein, the length of hawser 3 is greater than the top of bracing frame 7 distance to base plate 6, and less than sales kit (SK) 5 fall rear wheel to the distance at bracing frame top with fall front wheel 2 arrive sales kit (SK) 5 apart from sum.
In the present embodiment, pulley 2 also can be replaced by a smooth iron, and an end of iron is connected the forked root of lifting platform 4, after hawser 3 is walked around from iron, is connected with baffle plate 1.
Use the fall-down test device in the present embodiment to test.Before falling, as shown in Figure 2, the baffle plate 1 that will connect hawser 3 earlier is placed on forked two yokes lifting platform 4, and make baffle plate 1 be placed on sales kit (SK) 5 wait to fall under the angle, hold sales kit (SK) 5 from the below, hawser 3 is walked around pulley 2 and is fixed at the top of bracing frame 7.When falling, the forked platform 4 of lifting is subjected to the downward hyperbar of test unit, and the initial velocity that causes with gravity and air pressure drops down prior to sales kit (SK) 5, and sales kit (SK) 5 is done the movement of falling object, because lifting platform 4 falls prior to sales kit (SK) 5, thereby does not influence the freely falling body falling process of sales kit (SK) 5; Meanwhile, pulley 2 and forked synchronized movement of lifting platform 4, the length of hawser 3 immobilizes, and forked whereabouts of lifting platform 4 causes pulley 2 to follow the whereabouts, along with pulley 2 lower whorls, then elongated by hawser 3 length vertically of pulley 2, and length in the horizontal direction shortens, baffle plate 1 shortens along with hawser 3 length in the horizontal direction and laterally moves to the direction of pulley 2, because forked falling speed of lifting platform 4 is faster than sales kit (SK) 5, therefore baffle plate 1 vertical direction except be subjected to action of gravity also be subjected to pulley 2 by hawser 3 to the downward component of its vertical direction that applies, so baffle plate 1 is vertically moving downward with the speed greater than acceleration of gravity G, its falling speed is also fast than sales kit (SK) 5, therefore can not influence the falling process of sales kit (SK) 5 freely falling bodies; In falling process, baffle plate 1 is gradually near the forked root of lifting platform 4, thereby shift out sales kit (SK) 5 under, and move to a side (as shown in Figure 3) close with pulley 2, making sales kit (SK) 5 fall the back in the mode of the movement of falling object directly bumps with base plate 6, finish angle fall-down test process, thus the accuracy of warranty test.
The utility model shifts out the sales kit (SK) bottom by adopting hawser and pulley with baffle plate, bump between sales kit (SK) 5 and the baffle plate 1 when having avoided V shape fall-down test device to carry out the angle fall-down test, make baffle plate not only play the supporting role before falling but also do not influence sales kit (SK) and fall the generation of colliding between back and the base plate, solved the inaccurate problem of test findings that causes because sales kit (SK) and baffle plate bump.This device be particularly suitable for big weight product carry out fall-down test the time use.
Embodiment 2:
Present embodiment is with the difference of embodiment 1: the structure that described baffle plate is withdrawn mechanism is different.
In the present embodiment, baffle plate is withdrawn mechanism and is comprised spring, and an end of described spring is connected with the forked root of lifting platform 4, and its other end is connected with baffle plate 1, and the natural length of described spring is less than the forked root of platform 4 and the distance between the baffle plate 1 of lifting.
Other structures in the present embodiment are all identical with embodiment 1, repeat no more here.
Before falling, baffle plate 1 is arranged under the sales kit (SK) 5, because the natural length of spring is lifted the root of platform 4 and the distance between the baffle plate 1 less than forked, so spring is in extended state; When falling, the rapid resilience of spring, baffle plate 1 being pulled away from the below of sales kit (SK) 5, sales kit (SK) 5 falls the back in the mode of the movement of falling object and directly bumps with base plate 6, finishes test.
To withdraw the advantage of mechanism be the bottom that can guarantee that baffle plate 1 can shift out sales kit (SK) 5 more quickly in falling process to baffle plate in the present embodiment.Disclosed technical scheme among this embodiment 2 is applicable to the bigger fall-down test of sales kit (SK) 5 weight, unlikelyly so that sales kit (SK) 5 can compress baffle plate 1 under original state is pulled back by spring force.
In above-mentioned disclosed two embodiment, baffle plate 1 is arranged on forked two yokes lifting platform 4 horizontally slidingly, makes that when forked baffle plate 1 together moves downward with the forked platform 4 of lifting when lifting platform 4 and being fallen by brute force to be higher than acceleration of gravity G.Here; should be appreciated that; shape of lifting platform described in the utility model is not limited to above-mentioned forked, and any design has the difformity opening and need to use baffle plate and baffle plate to withdraw the device that falls that mechanism guarantees the accuracy of angle fall-down test to include in protection domain of the present utility model.
Be understandable that above embodiment only is the illustrative embodiments that adopts for principle of the present utility model is described, yet the utility model is not limited thereto.For those skilled in the art, under the situation that does not break away from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement also are considered as protection domain of the present utility model.
