Universities and colleges, costly, the enterprise of these financial strains or the big of inclined literal arts, special secondary school universities and colleges are often for fluid pressure type material stretching-machine price
Doing stretching experiment will entrust other unit to carry out, and cause bigger difficulty to it, and fluid pressure type material stretching-machine there is also
Some defects of its own are difficult to overcome, hydraulic system easy permeability during such as pressurize, and its hydraulic part maintenance cost is higher etc..
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of letter simple in construction, easy to operate, with low cost
Easily stretchable experimental provision.
The technical solution adopted in the utility model is：A kind of simple stretch experimental provision, including counterweight component, load-bearing branch
Frame, fixed pulley group, tightrope I, tightrope II, running block and specimen holder fixture；Described fixed pulley group is fixedly mounted on load-bearing
On support, tightrope I one end is fixed on fixed pulley group or running block, and running block is connected into by tightrope I with fixed pulley group
One, the tightrope I other end is connected with counterweight component；Tightrope II upper end is connected with running block, and lower end is pressed from both sides with specimen holder
The upper end connection of tool, the lower end of specimen holder fixture is connected with support bracket bottom.
In above-mentioned simple stretch experimental provision, in addition to safety rope, the upper end of safety rope is connected with tightrope II lower ends, pacified
The lower end restricted entirely is connected with support bracket bottom.
In above-mentioned simple stretch experimental provision, provided with three runners, the tightrope I other end at the top of described support bracket
Three runners are bypassed, are connected with counterweight component.
In above-mentioned simple stretch experimental provision, in three runners at the top of described support bracket, most one of inner side
It can move.
In above-mentioned simple stretch experimental provision, the length of described safety rope is more than after specimen holder fixture clamping test specimen
Length, the difference of the length after the length and specimen holder fixture clamping test specimen of safety rope is less than counterweight component bottom from the ground
Distance.
In above-mentioned simple stretch experimental provision, described tightrope I and tightrope II includes the core of wire quality, core
Outside is wrapped with torsade.
In above-mentioned simple stretch experimental provision, described support bracket is welded using square steel tube.
Compared with prior art, the beneficial effects of the utility model are：The utility model design principle is simple, operation side
Just, overall structure is simple, compact, and manufacturing process is simple, and cost and maintenance cost are cheap, and be particularly suitable for use in cash-starved small enterprise
Big, the special secondary school universities and colleges of industry and some inclined literal arts.
Brief description of the drawings

Fig. 2 is the structural representation of support bracket of the present utility model.
In figure：1- counterweight components, 2- support brackets, 3- fixed pulley groups, 4- tightropes I, 5- running block, 6- specimen holders folder
Tool, 7- safety ropes, 8- tightropes II, 11- counterweight, 21- runners.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As Figure 1-Figure 2, the utility model include counterweight component 1, it is support bracket 2, fixed pulley group 3, tightrope I 4, dynamic
Assembly pulley 5, specimen holder fixture 6, safety rope 7 and tightrope II 8, described support bracket 2 are welded using square steel tube, are held
The top of weight support 2 is provided with three runners 21, and one of most inner side can move in three runners 21, can be according to different use works
Condition is adaptively moved.
Described fixed pulley group 3 is fixedly mounted on support bracket 2, and running block 5 passes through tightrope I 4 and fixed pulley group 3
Series connection is integral.Tightrope I 4 one end is fixed in fixed pulley group 3, can also be fixed on running block 5.Tightrope I's 4 is another
One end bypasses three runners 21 at the top of support bracket 2, is connected with counterweight component 1, positioned at the side of support bracket 2.Described
Tightrope II 8 upper end is connected with the bottom of support bracket 2, and lower end connects with the upper end of specimen holder fixture 6 and safety rope 7 respectively
Connect, the lower end of specimen holder fixture 6 and safety rope 7 is connected with the bottom of support bracket 2.Described tightrope I 4 and tightrope II 8 is wrapped
Include and be wrapped with torsade on the outside of the core of wire quality, core.The length of described safety rope 7 is more than the clamping of specimen holder fixture 6
The difference of length after length after test specimen, the length and the clamping test specimen of specimen holder fixture 6 of safety rope 7 is less than the bottom of counterweight component 1
