Description

The three-dimensional adjustable test tube rack

The utility model relates to a kind of laboratory occasion that is used for that is made of fixing parts such as plate holder, spring clip plate, straight-bar, elastic hose, tightening steel wire and tightening wheel and clamps test tool, clamps the three-dimensional adjustable test tube rack of utensils such as chemical test test tube in particular for chemical laboratory.

At present, when chemistry, physics laboratory or factory floor experimentize, employed stand for experiment has a variety of, the support of these experiment usefulness mainly is made up of fixed head, straight-bar, cross bar and adjusting screw etc., general structure is vertically to be shaped on straight-bar on the fixed head, the cross bar that but cover system up-down adjustment is slided on the straight-bar, cross bar is made up of many intersections, but every cross bar two ends are shaped on the clip of clamping test tube or other clipped objects; In addition, also have knockdown experimental stand, the design feature of these stands generally is arranged to form by many pack supports, and its group number can be chosen with the experiment place, and is more flexible and changeable.But no matter be separate unit support or combination stand, in use, clipped object all is subjected to certain restriction in the adjusting of locus, especially when clipped object need move towards to be not straight line laterally vertically regulating simultaneously, the current experiments bracket adjustment is got up and is bothered more, and, often make some chemical experiment when installing instruments device, incur loss through delay experimental period because the time of regulating takies longlyer.End is got up, and (platform) frame that the current experiments chamber is used has the structure clumsiness, uses to regulate not nimblely, and the space orientation range of adjustment is little, outstanding shortcoming such as lose time.

Goal of the invention of the present utility model is to overcome the shortcoming that exists in the prior art, seeking to design and produce a kind of its straight-bar adopts and can combine by directly crooked flexible metal conduit and steel wire, novelty simple in structure, adjusted is convenient, the adjusting spatial dimension is big, time saving and energy saving, especially can be directly be elastic hose and arbitrarily choose the space orientation of clipped object with hand by the bent support bar, realize the purpose of the disposable adjusting success of three dimensions.

In order to realize the foregoing invention purpose, the utility model mainly is made up of fixing parts such as plate holder, fixed screw, spring clip plate, straight-bar, elastic hose, bracing frame, tightening wheel, jig plate and clamping screw.Fixedly plate holder, fixed screw and the spring clip plate trinity, fixedly leave the space between plate holder and the spring clip plate, can insert experiment table top etc. so that stand is fixed on the firm stylobate, spring clip plate and fixedly the screw hole of plate holder mate with fixed screw; Straight-bar one end by clamping in spring clip plate, the other end docks with elastic hose, the other end of elastic hose is shaped on bracing frame, be shaped on tightening wheel and wire clip in the frame of frame bracing frame, the other end of frame bracing frame is shaped on Trinitarian rigidity jig plate and clamping screw, the space can fold up check bar, test tube or other clipped objects in the jig plate, and whole test tube rack can be adjusted the orienting station of clipped object in the space by stirring bracing frame.

The utility model is compared with the current experiments stand, have novel structure simple, regulate easy to operate, space orientation flexibly, accurately, can save advantages such as experimental period and manpower, can be occasion such as laboratory a kind of desirable experimental stand be provided.

Fig. 1 is the structural principle synoptic diagram of the utility model.

Be further described below in conjunction with accompanying drawing.The utility model adopts common process method processing and fabricating to form, material of main part is selected the corrosion resistant metal rigid material for use, and mainly containing fixedly, plate holder 1, fixed screw 2, spring clip plate 3, straight-bar 4, elastic hose 5, tightening wheel 6, wire clip 7, jig plate 8, clamping screw 9, bracing frame 10, tightening steel wire 12 and tightening handle 13 are formed by combining.Leave the space between straight tabular fixedly plate holder 1 and the horse-hof shape spring clip plate 3,, be convenient to make fixedly plate holder 1 and spring clip plate 3 clampings and its whole test tube rack is stabilized on the experiment table (table) by regulating fixed screw 2 in order to inserting experiment table desktop or other matrixes; Regulate fixed screw 2 simultaneously and can also make horse-hof shape spring clip plate 3 degrees of tightness, so that clamping straight-bar, straight-bar 4 inserts in the horse-hof shape spring clip plate 3, its other end and snakeskin shape becket shell type elastic hose 5 are affixed, the other end of elastic hose 5 and frame bracing frame 10 are affixed, be shaped on the mechanism of the clamping tightening steel wire 12 of tightening wheel 6 and wire clip 7 compositions in the frame of bracing frame 10, the other end of frame bracing frame 10 and horse-hof shape jig plate 8 and clamping screw 9 are made adjustable integrative-structure, can clipped object 11 be taken out or clamp degree of tightness jig plate 8 by rotating clamping screw 9; Clipped object 11 can be single test tube, also can be the combination experiment bar that contains a plurality of anchor clamps ends.

Snakeskin shape becket shell type elastic hose 5 can adopt the rigid hose of the similar desk lamp branching rod structure in the routine techniques, cover system tightening steel wire 12 in its heart cavity, the weldering of tightening steel wire 12 1 ends is on straight-bar 4, the other end is threaded the back clamping in wire clip 7 with tightening wheel 6, and can pick and place by stirring tightening handle 13, when the turn tightening takes turns 6, can in certain distance, regulate the tightness of tightening steel wire, make elastic hose stable strong more, so that stablize the location of clipped object 11 in the space.
