Abstract

The utility model relates to a test bracket for supporting a sample piece. The utility model is characterized in that the test bracket comprises a base and at least three height-adjustable struts, and the struts are arranged in a polygonal shape and erected on the base. From top to bottom, each strut can be formed by sequentially connecting a plurality of short columns detachably, and the lowest short column is connected with the base by screw thread. Compared with the prior art, as the height of each strut is adjustable, when different shapes of the sample pieces are directly placed on the struts, different filling blocks do not need to tentatively pad to be the level state or the higher state, the required position requirements of the sample pieces can be met only by adjusting the height of the struts, and the height is conveniently and fast adjusted, thereby effectively ensuring the smooth and accurate test.

Description

A kind of test support that supports exemplar

Technical field

The utility model relates to a kind of support, specifically refers to a kind of test support that supports exemplar.

Background technology

At present, in the test of test sample, exemplar does not often have special-purpose bracing or strutting arrangement.For example, electroplate exemplar and adopt different cushion blocks to level up or the bed hedgehopping exemplar usually in the thickness test of electroplating exemplar.But because the shape of plating exemplar is usually very irregular; therefore adopting the mode of above-mentioned cushion block to be fixed up relatively wastes time and energy; and level up or bed hedgehopping after; because the instability of cushion block makes that electroplating the exemplar surface is difficult to reach the required levelness of test; to such an extent as to the phenomenon of leakage or test interruption appears in regular meeting in test process; the result causes work efficiency low, and influences accuracy of test.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned prior art present situation, provides a kind of and puts for difform exemplar, and regulate the test support of support exemplar easily and fast.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the test support of this support exemplar comprises base and at least three adjustable for height pillars, and each described pillar is arranged in polygon-shaped and stands upright on the described base.

As further improvement of the utility model, each described pillar can be from top to down be formed by connecting by a plurality of short columns dismountings successively, and the short column of below is threaded mutually with described base.Preferable scheme is that each described pillar can be formed by connecting by five short columns, wherein peg graft mutually and fix with bearing pin radially in the upper end of the lower end of first short column and second short column, the lower end of second short column is threaded mutually with the upper end of the 3rd short column, the upper end of the lower end of the 3rd short column and the 4th short column plugs, and by radial screw location, the upper end close-fitting grafting mutually of the lower end of described the 4th short column and the 5th short column.Such pillar can obtain bigger adjustable height scope.

The upper end of described first short column also is provided with a sheath, bumps firmly with exemplar avoiding.

Described pillar is preferably three or four, and is simple in structure like this, can satisfy simultaneously and support requirement.

Compared with prior art, because each pillar adjustable height of the present utility model, therefore when difform exemplar directly is put on each pillar, need not to level up or bed hedgehopping with different cushion blocks is tentative, as long as promptly can reach exemplar test desired position requirement by the height of regulating each pillar, and regulate easily and fast, can guarantee effectively to test successfully, carry out exactly.

Fig. 2 is the vertical view of base among Fig. 1;

Fig. 3 is the decomposing schematic representation of a pillar and base wherein among Fig. 1;

Fig. 4 is the right view of first short column and second short column among Fig. 3.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, the test support of this support exemplar comprises a base 1 and three adjustable for height pillars 2, and in the present embodiment, each pillar 2 is positioned at vertex of a triangle, promptly is arranged in triangle, and stands upright on the above-mentioned flat base 1.

In order to regulate the height of each pillar to greatest extent, in the present embodiment, each pillar is formed by connecting by five short column dismountings from top to down successively, promptly include first short column 21 from top to down successively, second short column 22, the 3rd short column 23, the 4th short column 24 and the 5th short column 25, their annexations each other are as follows: the lower end of first short column 21 is plugged in the jack of upper end of second short column 22, and have radial hole a in the plugging position of first short column and second short column, see also Fig. 3 and Fig. 4, radially bearing pin 3 is plugged in this radial hole, so that first short column and second short column fix after pegging graft; The lower end of second short column 22 has external thread, and the upper end of the 3rd short column 23 has screw hole, and the lower end of second short column is threaded in the screw of the 3rd short column upper end; The lower end of the 3rd short column 23 is plugged in the axially extending bore of the 4th short column, and on the sidewall of the 4th short column, have a screw 241 radially, one screw 3 is screwed onto this radially in the screw, the sidewall of the head of screw 3 and the 3rd short column 23 offsets, so that after the 3rd short column is plugged on the 4th short column, position by this screw; Directly insert in the lower end through hole of the 4th short column 24 upper end of the 5th short column 25, and both are that interference is joined; The lower end of the 5th short column 25 then has external thread, and accordingly, the lower end that has three screw 11, the five short columns 25 of distribution triangular in shape on the base 1 is threaded in the corresponding screw.

For fear of the exemplar of damaging, also be provided with the sheath 4 of a plastic material in the upper end of above-mentioned first short column.

During use, as long as the exemplar of Different Rule directly is put on the pillar, it is short to rotate second short column or the 5th post then as required; Perhaps rotary screw is regulated the 3rd short column and is inserted into the degree of depth in the 4th short column, promptly can change the relative position between each short column, has finally regulated the height of each pillar, puts requirement thereby can reach the required exemplar of test apace.

Except the foregoing description, the utility model can also include other embodiments, adopt four as pillar, perhaps each pillar is threaded successively by two, three or four short columns and forms, and perhaps adopts the stretching structure of antenna to reach adjustable for height purpose between each short column.The technical scheme that all employing equivalents or equivalent substitute mode form all should fall within the protection domain of the utility model claim.
