Connection, is respectively equipped with buffer, the load guide rod upper end is arranged with a crash panel, the crash panel bottom surface in the load guide rod both sides
It is in contact with each buffer.
Described four angles of base end face are respectively equipped with a foot pad.
Each seat guide rod is vertically mounted on base two ends, respectively this guide rod upper end be respectively cooperating with a fixed seat with it is upper
Crossbeam corresponding end is connected.
The specimen holder two ends are slidably connected on corresponding seat guide rod by a linear bearing respectively, on the specimen holder
Provided with a sample setting area, the sample setting area is enclosed to set by some fixed blocks to be formed.
Described connecting rod one end is hinged with oscillating bearing, and the connecting rod other end is hinged with deviation wheel.
The crash panel coordinates a connection piece to be sheathed on load guide rod upper end.
The beneficial effects of the utility model are：Its motor via reducer band movable eccentric wheel rotates, and eccentric wheel passes through even
Extension bar promotes the upper and lower motion of specimen holder, when specimen holder is moved upwards, sample will be promoted to impact on counterweight, Ran Hou
Under the guiding of seat guide rod, counterweight drives buffer shock plate to move upwards by load guide rod, adjusts the position of entablature,
Specimen holder is set crash panel is departed from buffer when moving to peak, impact strength now is just equal to the lotus of counterweight
Weight, and then fixed load impact fatigue test is carried out to sample；The load mode generation that the utility model passes through the counterweight of fixed heavy burden
The side that the fixed load for having replaced conventional test device to be combined using actuator (making moving cell), strength sensor and capture card is impacted
Method, realize high speed impact remain constant load not with tested sample be recessed and reduce impulsive force, improve fixed load
The stability of impact, reduction fault rate, reduction are safeguarded and after cost so that fixed load impact becomes more practical, quick, height
Effect；The utility model can be used for the fixed load shock-testing of the multi-class products such as foam, spring bag, seat, using scope more
To be extensive.
