Abstract
The utility model discloses a deadweight lever switching device used for a deadweight lever combined type force standard machine, which comprises a lever loading frame, an upper tray, a lower tray, a connection rod and a lifting and falling mechanism, wherein the lever loading frame comprises an upper cross beam of the frame and a lower cross beam of the frame; the upper tray is arranged on the lower cross beam of the frame; the connection rod passes through the central part of the lower cross beam of the frame and is vertical with the lower cross beam of the frame; one end of the connection rod is connected with the upper tray, and the other end of the connection rod is connected with the lower tray; and the lifting and falling mechanism is arranged below the lower tray and connected with the connection rod. The device can enable the deadweight lever combined type force standard machine to switch easily, conveniently and quickly between a deadweight machine and a lever machine, and the device has the advantages of simple structure, saved time and labor, reduced wear, long service life and the like.
Description
Technical field
The utility model relates to a kind of force standard machines apparatus field, particularly relates to the dead weight lever switching device shifter for dead weight lever combined type force standard machine.
Background technology
Dead weight lever combined type force standard machine is that invented in the last few years a kind of can be as Dead Weigh Force Standard Machine, the multi-functional device for measuring force that can use as Lever-type Standard Force Measuring Machine again.But the reaction frame of traditional dead weight lever combined type force standard machine hang below the tie-beam, between the tension and compression space, when using as the dead weight machine, to unload reaction frame, and load onto again reaction frame when using as Lever-type Standard Force Measuring Machine, waste time and energy, cause easily wearing and tearing and error, cause the manpower and materials waste, affected machine service life.
The utility model content
For above-mentioned deficiency of the prior art, the utility model fundamental purpose provides a kind of simple in structure, can the efficient and convenient device that allows dead weight lever compounding machine switch between dead weight machine and Lever machine.
For achieving the above object, the utility model adopts following technical scheme: a kind of dead weight lever switching device shifter, be used for dead weight lever combined type force standard machine, comprise lever-loading framework, top tray, lower tray, connecting link and elevating mechanism, described lever-loading framework comprises frame upper beam and framework sill, described framework sill is provided with top tray, and described connecting link runs through in the middle part of the described framework sill and perpendicular to described framework sill; Described connecting link one end connects top tray, and the other end of described connecting link connects lower tray; Described elevating mechanism is located at described lower tray below and is connected described connecting link.Preferably, described lever-loading framework acts on the lever of dead weight lever combined type force standard machine, and whole device is fixed on the dead weight entablature partly of dead weight lever combined type force standard machine.
Dead weight lever switching device shifter described in the utility model is used for dead weight lever combined type force standard machine, described lever-loading framework acts on the lever of dead weight lever combined type force standard machine, and whole dead weight lever switching device shifter is fixed on the dead weight entablature partly of dead weight lever combined type force standard machine.
During use, the switching that dead weight lever combined type force standard machine carries out is realized in the position that changes top tray and lever-loading framework and lower tray and elevating mechanism by elevating mechanism between dead weight machine and Lever machine.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the utility model dead weight lever switching device shifter;
Fig. 2 is that the utility model dead weight lever switching device shifter is assemblied in the structural representation on the dead weight lever combined type force standard machine;
Each parts mark is as follows among the figure: 1-lever-loading framework, 2-top tray, 3-lower tray, 4-elevating mechanism, 5-connecting link, 6-lever, 10-frame upper beam, 11-framework sill.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
Please refer to Fig. 1 and Fig. 2, embodiment of the present utility model: a kind of dead weight lever switching device shifter, be used for dead weight lever combined type force standard machine, comprise lever-loading framework 1, top tray 2, lower tray 3, connecting link 5 and elevating mechanism 4, lever-loading framework 1 comprises frame upper beam 10 and framework sill 11, framework sill 11 is provided with top tray 2, and connecting link 5 runs through framework sill 11 middle parts and perpendicular to framework sill 11; Connecting link 5 one ends connect top tray 2, and the other end of connecting link 5 connects lower tray 3; Elevating mechanism 4 is located at lower tray 3 belows and is connected connecting link 5.
Dead weight lever switching device shifter in the present embodiment is used for dead weight lever combined type force standard machine, lever-loading framework 1 acts on the lever 6 of dead weight lever combined type force standard machine, and whole dead weight lever switching device shifter is fixed on the dead weight entablature partly of dead weight lever combined type force standard machine.
In use, when dead weight lever combined type force standard machine uses as the dead weight machine, start elevating mechanism 4 drive connecting links 5 picking-up top tray 2 top tray 2 and lever-loading framework 1 are thrown off, namely do not keep in touch with lever 6, then test, finish the effect of dead weight machine.And when dead weight lever combined type force standard machine uses as Lever machine, start elevating mechanism 4 drive connecting links 5 lower tray 3 and elevating mechanism 4 are disconnected, i.e. disconnection contacts with dead weight part loading frame, and then begins to test, and finishes the function of Lever machine.
Being different from traditional dead weight lever combined type force standard machine need to load and unload reaction frame and switch between dead weight machine and Lever machine, dead weight lever switching device shifter of the present utility model only need to utilize elevating mechanism 4, the switching of dead weight lever combined type force standard machine between dead weight machine and Lever machine realized in the position that changes top tray 2 and lever-loading framework 1 and lower tray 3 and elevating mechanism 4, have simple in structure, easy to operate, time saving and energy saving, reduce wear, increase the characteristics such as serviceable life.
More than dead weight lever switching device shifter that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; all will change in specific embodiments and applications; in sum; this description should not be construed as restriction of the present utility model, and all any changes of making according to the utility model design philosophy are all within protection domain of the present utility model.
