Accompanying drawing with reference to the embodiment of the present invention is explained and illustrated to the technical scheme of the embodiment of the present invention, but under
State embodiment and be only the preferred embodiments of the present invention, and not all.Based on the embodiment in embodiment, those skilled in the art
On the premise of not making creative work, obtained other embodiment, broadly falls into protection scope of the present invention.
Embodiment 1.
The present invention provides a kind of snap arm leading screw tension grip.
In the present embodiment, snap arm leading screw tension grip, snap arm leading screw tension grip is installed on static load test
Machine, including the towing plate 1 for drawing snap arm leading screw to be measured, pull towing plate 1 pull bar 2, pull pull bar 2 pull plate 3 with
And for snap arm leading screw tension grip being connected to the connector 4 of dead load tester；Connector 4 is welded in pull plate 3,
Pull plate 3 using rectangular slab and is provided with two the first connecting holes, and two the first connecting holes are located at respectively in rectangular slab minor face
The position of point, towing plate 1 using rectangular slab and is provided with two the second connecting holes, and two the second connecting holes are located at respectively near rectangle
The position at plate minor face midpoint, the central spot of towing plate 1 is provided with through hole 11, in order to through the leading screw in snap arm leading screw to be measured.Draw
Bar 2 is provided with two, and the two ends of pull bar 2 are located at the first connecting hole and the second connection in the hole, the fixation of pull bar 2 and pull plate 3 respectively
There is two ways, a kind of mode is not passed through the first connecting hole or the second connecting hole for pull bar 2, now pull bar 2 is using the side of welding
Formula is fixing with towing plate 1 or pull plate 3；Another way is that pull bar 2 passes through the first connecting hole or the second connecting hole, the present embodiment
Using this kind of mode.
Pull plate 3 includes the first inner surface, and towing plate 1 includes the second inner surface, the first inner surface just to the second inner surface,
Second inner surface is provided with two pieces of cushion blocks 12, is symmetrically welded in the both sides of through hole 11, close to a group leader side of towing plate 1, uses
To protect the projection in the middle part of snap arm in snap arm leading screw to be measured.
Also include the first nut 5, for increasing intensity, the first nut 5 is provided with four, and the cylinder of pull bar 2 is provided with screw thread, four
