The center of the column beam is provided with a top hook 2, the center of the lower beam of the brace rod 3 is provided with a hanging ring 8, which changes the spring dial hand balance into a spring table balance, not only ensures the precision of the spring hand balance, but also facilitates the weighing, and the manufacturing cost is only 60% of the existing spring table balance. After the implementation, the wood beam scale has a wide market, and is an urgent need replacement product for eliminating the wood beam scale in 1997.
Description
The utility model relates to a kind of spring scale hand scale special stand, belongs to the used a kind of utility appliance of measuring apparatus.
Existing spring scale hand scale does not have special stand, when claiming thing, can only be portable, and firmly many if alleged material is heavier, the frequent use not only consumes one's strength, and places inconvenience, limited its usable range.
The purpose of this utility model is to provide a kind of spring scale hand scale special stand, and spring scale hand scale is fixed on it, becomes the spring scale counter scale, both guaranteed the precision of spring scale hand scale, limit cheating again, both be applicable to fixedly stand, also be suitable for huckster.
Technical solution of the present utility model is, this spring scale hand scale special stand, comprise base 9, the column 4 that is connected as a single entity with this base, its special character is, be provided with strut 3 in the framework that column 4 forms, four groups of forks of four groups of forks by being positioned at their fronts of strut 3 and column 4, back are hinged; Two groups of left and right both sides that are distributed in column, strut epimere of four groups of forks (front or rear), two groups of left and right both sides that are distributed in column, strut hypomere in addition.Every group of fork is made of short fork 6, long fork 7.One end of short fork 6 is hinged on the strut 3, and the other end is hinged with an end of long fork 7, and the other end of long fork 7 and column 4 are hinged, about two groups of forks with the common central axis line symmetry of strut 3, column 4.The initial angle of short fork 6 and long fork 7 is 5 °≤α<90 °.The skyhook 2 of fixedlying connected with it is established in the center of end floor beam on the column 4.The suspension ring 8 of fixedlying connected with it are established in the center of 3 times end floor beams of strut.Column 4 is that the rod member of flute profile constitutes by xsect.The two vertical beam lower ends made from the flute profile rod member are fixedly connected on the base 9, and their upper end is connected as one by crossbeam, and skyhook 2 is fixed on the geometric center point of crossbeam.Slot on the crossbeam, so that strut 3 slides in groove.Column 4 also can be made of four vertical beams, five crossbeams, and the lower end of four perpendicular roots is fixedly connected on the base 9, and the upper end connects as one by five crossbeams, and wherein one is positioned at the middle part, so that fixing skyhook 2.A kind of version of strut 3 is, is that the rod member of flute profile is processed into the rectangle closure frame by xsect, wherein fixed tray support and suspension ring 8 respectively on the geometric center point of upper and lower crossbeam.Another kind of version is, it is by four vertical beams, and upper and lower each five crossbeam constitute a rectangle closure frame, and wherein each crossbeam is positioned at the middle part up and down, and is parallel with two crossbeams that are positioned at limit portion, with other two beam vertical.Difference fixed tray support and suspension ring 8 on the geometric center point of the upper and lower crossbeam in the middle part of being positioned at.
The technical program mode preferably is to make in every group of fork, the length sum of the length of long fork 7 and short fork 6 is greater than 1.25 times of the metering spring impulse stroke of waiting to hang spring scale hand scale, and the initial angle α of the two is less than 45 °, greater than 5 °, can avoid like this dead point occurring at the volley and be stuck, guarantee fork and strut 3 motions flexibly, guarantee to wait to hang the maximum range of metering spring hand scale.The effect of eight groups of forks, the one, strut 3 is connected on the column 4, the 2nd, guarantee strut 3 and wait to hang spring scale hand scale no matter have or not weight, be in equilibrium state all the time, make and wait to hang spring balance and neither rotate, do not tilt yet.Both guarantee the precision of scale, and avoided illegal businessman to carry out the activity of few jin of weak point two again.In case because scale and support Installation and Debugging are accurate, any wrongful operation all will make the strut out of trim, at this moment, spring balance shows the weight of material, and is little than actual weight.At this moment because size, the structure of eight groups of forks are the same, during installation, make about them again, all around symmetry, symmetrical two groups of forks partner mutually and extremely cut with scissors, thereby in same plane, just formed up and down two pairs of dead hinges, thus guarantee that the hand scale can not vacillate now to the left, now to the right or tilt in the course of the work, can not rock back and forth or tilt forward and back yet, make and wait that the central axis of pacifying the hand scale overlaps all the time with the central axis of bearing, thereby can accurately weigh the weight of article.
Because the proposition of the technical program makes spring scale hand scale that special stand arranged, and has guaranteed the precision of scale, helps the weighing of weight again, has also alleviated manual labor, has enlarged the range of application of spring scale hand scale, prevent illegal businessman's cheating, lead the consumer into a trap.And cost is low, only is 60% of spring scale counter scale.
Accompanying drawing and drawing explanation:
The structural representation of an embodiment of Fig. 1-the utility model;
The vertical view of Fig. 2-Fig. 1;
Fig. 3-user mode reference diagram of the present utility model.
Wherein: the 1-scale pan, 2-skyhook, 3-strut, 4-column, 5-hand scale, the short fork of 6-, the long fork of 7-, 8-suspension ring, 9-base.
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying the utility model.As Fig. 1~shown in Figure 3, it is that the rod member of flute profile processes that the strut 3 of present embodiment, column 4 are xsect.The lower end and the chassis 9 of 4 two vertical beams of column are fixedly connected, and upper end and crossbeam join, and establish groove on the crossbeam, so that strut 3 can be slided within it, skyhook 2 is fixed on the central point of set groove cover plate.Strut 3 is that suspension ring 8 are established in the center of sill by two vertical beams and two rectangle closure frames that crossbeam constitutes, and the tray supporter connecting hole is established in the center of entablature, so that tray supporter is connected on it.Strut 3 is articulated as one by 8 groups of forks with column 4, as shown in Figure 1.The short fork 6 of four groups of forks of front is followed successively by C, D, D ', C ' with the pin joint of strut 3, long fork 7 is followed successively by A, B, B ', A ' with the pin joint of column 4, short fork 6 is followed successively by E, F, F ', E ' with the public pin joint of long fork 7, long fork 7 and short fork 6 sums are to wait to hang 1.25 times of spring scale hand scale spring travel, are 5cm here.Their initial angle α is 30 ° (strut 3 is the same with the annexation of column 4 back).Principle of work is, at first the drop handle with spring scale hand scale hangs on the skyhook 2, and hook is connected with suspension ring 8, and at this moment spring scale hand scale is fixed on the support, and will adjust the zero-bit of pointer.If object is placed on the pallet 1, then the weight of object presses down strut 3, and strut 3 makes the pointer rotation of spring scale hand scale, indication weighed object weight again by suspension ring 8.When strut moved down, the long fork of every group of fork was respectively around an A, B, A ', B ' swing, and short fork 6 is done plane motion around a C, D, C ', D ' respectively.Because making a concerted effort of long fork 7 and short fork 6 is vertical with gravity direction all the time, so make a concerted effort the size of object gravity is not had to influence,, thereby guaranteed that the hand scale can not vacillate now to the left, now to the right or tilt again because of left and right sides fork group symmetry, guaranteed weighing precision.
