Embodiment
For a further understanding of the utility model, the utility model preferred embodiment is retouched with reference to embodiment
State, but it is to be understood that these descriptions are simply to further illustrate feature and advantage of the present utility model, rather than to this practicality
The limitation of new claim.
It is the preferred embodiment of the resistance to static test device of low-tension distribution box of the present utility model as shown in Figure 1, it includes gold
Belong to and support 2 is installed on the base 1 of table top, base 1, the support 2 is used to fix guide rail 3.Guide rail 3 is set to two, and one end is solid
Due on base 1, other end connecting bracket 1.In the inside of guide rail 3, be provided with can be movable in guide rail movable part, the activity
Portion is connected with the chain in guide rail, is pumped under the drive of chain along guide rail.
The device also includes pressing plate 5 and the suspension bracket 4 for supporting pressing plate 5, wherein, the two ends of suspension bracket 4 respectively with guide rail 3
Movable part connection, pressing plate 5 positioned at the connector of center by being installed on suspension bracket 4.It is preferred that, pressing plate 5 is by metallic plate
It is made, its area is more than the area of low-voltage distribution roof box to be measured.Between pressing plate 5 and suspension bracket 4, provided with there is pressure sensor,
For gathering pressure of the pressing plate 5 to low-tension distribution box top plate to be measured.
On the other hand, the two ends of guide rail 3 are additionally provided with the sprocket wheel matched with chain, for support and drive chain.Wherein, position
Sprocket wheel in bottom is driven by motor.Specifically, motor includes AC gear motor 6 and stepping reducing motor, wherein exchange subtracts
