Counterweight fixing device 3 is controlled to drive test counterweight 2 to rise or fall.In order to reach labour-saving purpose, the free end of test lever 6
Distance to fulcrum is more than the end that is connected with counterweight fixing device 3 to the distance of fulcrum, that is, for depressing free end power
Arm is more than the arm of force of test counterweight 2 and counterweight fixing device 3.
The process of test will be described in detail in detail by tested handbarrow 7 below, the bottom that handbarrow 7 has scalable cooperation is solid
Determine handrail 7.1 and top movable handrail 7.2.In order that the result of test more prepares, tested handbarrow 7 is except fixing handrail
7.1st, outside scalable handrail 7.2, also installed simulation load 7.3 additional.
In test mode, the lower pressure side pushing test lever 6 drives counterweight fixing device 3 to rise, by tested hand push
After car 7 is placed on test position (lower section of the movable machine frame 1.1 of frame 1), unclamp test lever 6, counterweight fixing device 3 and test
Counterweight 2 declines together, and what now whole gravity of test counterweight 2 and its fixing device 3 acted directly on tested handbarrow 7 can
On flexible armrest 7.2, to scalable 7.2 1 downward pressure of handrail, simulate handbarrow 7 scalable handrail during carrying out
The 7.2 downward power being subject to.
When the model of tested handbarrow 7 changes, the distance on its scalable handrail 7.2 top to ground is also therewith
Change, the distance on therefore counterweight fixing device 3 bottom to ground changes with the need therewith.This meets this needs and asks,
In barrow armrest test device of the present utility model, frame 1 is telescopic connection, fixes pipeline section 1.2 and movable pipeline section 1.1
For tubular structure, fixing pipeline section 1.2 size is larger, takes off regulating bolt 1.3, movable pipeline section 1.1 can be fixed in pipeline section 1.2 and stretch
Contracting, now the distance on counterweight fixing device 3 bottom to ground also changes therewith, after being adjusted to suitable distance, by regulating bolt
1.3 also cross movable pipeline section 1.1 and the hole fixing pipeline section 1.2, you can so that the two is fixed.
In sum, barrow armrest test device of the present utility model at least has advantages below：
(1) frame both sides are respectively arranged with guider, test counterweight can be controlled to move up and down along guide, and survey
