Brief description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure：1- bases；2- drawer type the storage box；3- support bars；4- rotating shafts；5- levers；6- slip caps；7- lock plungers；
8- mounts ring；9- sheet rubbers；10- calibrates regulation cock.
Specific embodiment：
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by what is shown in accompanying drawing
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With new scope.Additionally, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily mixing
Confuse concept of the present utility model.
As shown in figure 1, this specific embodiment uses following technical scheme：It includes base 1, drawer type the storage box 2, branch
Strut 3, rotating shaft 4, lever 5, slip cap 6, lock plunger 7, mounting ring 8, sheet rubber 9, calibration regulation cock 10；The front end peace of base 1
Equipped with drawer type the storage box 2, the inside of drawer type the storage box 2 is placed with several counterweights, and the upper end of base 1 is provided with support bar 3,
The upper end of support bar 3 is connected by rotating shaft with the middle part of lever 5, and the two ends of bar bar 5 are mounted on calibrating regulation cock 10, lever 5
Both sides be socketed with slip cap 6, the upper end of slip cap 6 is provided with lock plunger 7, and the lower end of slip cap 6 is provided with mounting ring 8,
The inside of mounting ring 8 is provided with sheet rubber 9, and sheet rubber 9 and offers cross bath.
Further, the upper and lower side of described lever 5 is mounted on wear plate.
Further, the bottom of described base 1 is provided with slipmat.
The operation principle of this specific embodiment is：When using, two slip caps 6 are slided into middle part or same size
Arm of force distance, now see whether lever balances, when out-of-balance, by adjust calibration regulation cock 10 realize calibration, experiment
When, arm of force distance is adjusted by slip cap 6, after the completion of regulation, locked by lock plunger 7, then corresponding counterweight is mounted
In mounting ring 8, after mounting, realized by the cross bath on sheet rubber 9 spacing, prevent counterweight from rocking and influence measurement data,
Operation is quick with regulation, efficiency high.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
