Wheel is connect with the input terminal of lever, and the lever is located on the second layer bracket of section bar support, the output end and pressure of the lever
Plate is fixedly connected.
In one embodiment of the invention, piston rod, the piston rod position are equipped between the cylinder and weight beam
In in the cylinder, and the piston rod can according to need and stretch.
In one embodiment of the invention, the first layer bracket of the section bar support is square bracket.
In one embodiment of the invention, the second layer bracket of the section bar support is square bracket open at one end.
In one embodiment of the invention, the second layer bracket contact point of the lever and the section bar support is lever branch
Point need to only be adjusted the position of balance pivot when needing to adjust different size of test force.
In one embodiment of the invention, the section bar support bottom end is equipped with third layer bracket, makes the structure of section bar support
It is more stable.
In one embodiment of the invention, pass through steel between the cylinder, weight beam, pulley and the input terminal of lever
Cord connection.
As described above, arrangements for automotive doors durability test apparatus of the invention, has the advantages that the present invention using cylinder
Electric cylinders are replaced with piston rod, and adjust the size of power output, strong flexibility, and convenient in carrying using the mode of adjustment balance pivot
Safety, save the cost.

Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
Please refer to Fig. 1.It should be clear that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate
The revealed content of specification is not intended to limit the invention enforceable so that those skilled in the art understands and reads
Qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size,
It does not influence still fall in disclosed technology contents under the effect of present invention can be generated and the purpose that can reach
It obtains in the range of capable of covering.Meanwhile cited such as "upper", "lower", "left", "right", " centre " and " one " in this specification
Term, be merely convenient to being illustrated for narration, rather than to limit the scope of the invention, the change of relativeness or
Adjustment, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of arrangements for automotive doors durability test apparatus, comprising: section bar support 1, cylinder 2, bullet
Spring dynamometer 3, pulley 4, lever 6, pressing plate 7, the section bar support 1 are double-layer scaffold, the first layer bracket of the section bar support 1
Be equipped with strut 8, the cylinder 2 is located on the strut 8 with weight beam 3, the weight beam 3 by pulley 4 and
The input terminal of lever 6 connects, and the lever 6 is located on the second layer bracket of section bar support 1, the output end and pressure of the lever 6
Plate 7 is fixedly connected.The piston rod 9 of cylinder 2 stretches out when starting, and the input terminal of lever 6 is because gravity naturally droops, the output of lever 6
End slightly tilts, so that pressing plate 7 be made to be detached from sample test face.When the piston rod 9 of cylinder 2 is withdrawn, 3 stress of weight beam is stretched
Long, when up being lifted the input terminal of lever 6 to horizontal position by pulley 4, the pressing plate 7 on the output end of lever 6 starts to connect
Touch test sample surface, continue to withdraw with 2 piston rod of cylinder, weight beam 3 generates bigger deformation, lever 6 it is defeated
Enter force value is held constantly to increase, the power that pressing plate 7 passes to sample test face also constantly increases, until the piston rod 9 of cylinder 2 is recovered to
Bottom, 3 deformation of weight beam reach maximum, and the power that pressing plate 7 passes to sample test face also reaches maximum.Because of the stroke of cylinder 2
Constant, the largest deformation of weight beam 3 is constant, i.e. the maximum, force of the input terminal of guarantee lever 6 is constant, as long as at this moment adjusting thick stick
The position of bar fulcrum 5, changes 6 fulcrum both ends length ratio of lever, i.e., changeable pressing plate 7 passes to the force value in sample test face.?
During 2 piston rod of cylinder withdraws or stretches out, weight beam 3 adds the tune to 2 input air pressure of cylinder as buffering
Section, can be realized required load and release time.If the output end of lever 6 can be realized by certain pulley blocks again
The output of different directions different size force value.
Specifically, being equipped with piston rod 9 between the cylinder 2 and weight beam 3, the piston rod 9 is located at the cylinder 2
It is interior, and the piston rod 9 can according to need and stretch.
Specifically, the first layer bracket of the section bar support 1 is square bracket.
Specifically, the second layer bracket of the section bar support 1 is square bracket open at one end.
Specifically, the second layer bracket contact point of the lever 6 and the section bar support 1 is balance pivot 5, when needing to adjust
When whole different size of test force, the position of balance pivot 5 need to be only adjusted.
Specifically, 1 bottom end of section bar support is equipped with third layer bracket, keep the structure of section bar support 1 more stable.
Specifically, being connected between the cylinder 2, weight beam 3, pulley 4 and the input terminal of lever 6 by wirerope.
In conclusion a kind of arrangements for automotive doors durability test apparatus provided by the invention, replaces electricity using cylinder and piston rod
Cylinder, and the size of power output is adjusted using the mode of adjustment balance pivot, simple and reliable for structure, strong flexibility is low in cost, can
Replicability is strong.
So the present invention effectively overcomes various shortcoming in the prior art and has high industrial utilization value.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
