Description
The utility model multipurpose chemical experimental stand is the carrier base that is used for installing various chemical experiment devices, is applicable to all kinds of schools chemistry teaching lecture experiment and chemical scientific experiment.
What be used at present chemical experiment device is installed is iron stand (being Square seat bracket), and iron stand generally only can be installed an instrument, and the experiment that device is complicated slightly often needs many iron stand amalgamations to use.Heat if desired in the experimentation and use alcolhol burner, generally make base, or hand-held alcolhol burner experimentizes with the wooden unit that thickness does not wait.The iron clamp of clamping instrument, dependence screws the ingot-shaped nut and fixes.Regulate inconvenience, waste time and energy, the integral experiment device that is assembled into, inconvenience is moved and dystopy.
The purpose of this utility model provides a kind of multipurpose chemical experimental stand; the simple cost of the structure of signing an undertaking is not high; good stability; can various chemical experiment devices be installed separately, easily, be convenient to again unload and rotatable stand, it is time-consuming many to solve the existing installation experimental provision of all kinds of schools chemical experiment; regulate not convenient; moving and the dystopy problem of complicated integral experiment device saved chemical teaching demonstration experimental period, promotes the demonstration effect.
Design design of the present utility model; at the various devices of having studied all kinds of schools chemistry lecture experiment and student experiment in group; adopt following scheme to realize: multipurpose chemical experimental frame primary structure has rotation parallel-moving type platform iron ring, rotary connector, adjustable hanging column group, main folder, sub-folder, extension clamp, clip, simple and easy clip, hanger, asbestos rack, cruciform joint, T junction, stator, column, tripod base.
Rotation parallel-moving type platform iron ring is called for short the platform iron ring, mainly is made of guide rail, sliding platform, button arm plastics clamp screw button.The needs that being used for the shelf rest alcolhol burner in experiment, supplies experiment to heat are set in during use on the column of tripod base, stator is housed down is used for the location, can do comprehensive adjusting.Upper-lower position is regulated, mobile stator.Position adjustments on the horizontal direction, the translation gliding platform is along the reciprocal translation of guide rail.Stop knob is tightened in the 360 ° of rotations about column is done of button arm, promptly is fixed.
Rotary connector mainly is made of turning cylinder, brace, movable brace.Turning cylinder and brace cast solid, rotary axle box is contained on the column, the bottom is equipped with and is accepted axle sleeve, be equipped with on the brace and hitch pile crown, movable brace adopts connecting screw to link to each other with brace, is drilled with the main folder jack, the sub-folder jack on the movable brace, little key is housed in the main folder jack, and clamping screw is equipped with in the side.Turning cylinder, accept axle sleeve, stop knob all is equipped with in sub-folder jack side, the location is used when being used for clamping.Rotary connector be used to peg graft main folder, sub-folder and hitch adjustable hanging column group.Be socketed in during use on the column of tripod base, in experiment, can locate respectively behind main folder, the sub-folder clamping laboratory apparatus and take a seat in main folder hole and sub-folder hole, be milled with the line of rabbet joint on the main folder handle, partly match with little keyhole internal projection during insertion, therefore main folder is once hand-hole, no matter go up, promptly be in duty where.Main folder also can be made 90 ° of pitch tilt around connecting screw and regulate, and the moving part of rotary connection can be done 360 ° of space rotations around column, needs braking then to tighten stop knob and gets final product the removable axle sleeve of accepting of up-down adjustment.
Adjustable hanging column group is the second mate altogether, mainly is made of hanging column, horizontal rod, is respectively applied for simple and easy clip, clip or the extension clamp that connects the clamping instrument by " ten " font joint or " T " font joint.Hanging column group (1) is socketed on the socket pile crown on the rotary connector, and hanging column can be made reciprocal translational adjustment along horizontal rod, also can make lift adjustment by cruciform joint.Hanging column group body is done 360 ° around the socket pile crown and is horizontally rotated, and the simple and easy clip or the clip that are installed on the hanging column can be done translation, lifting and rotation adjusting equally.It is identical with above-mentioned hanging column group (1) that hanging column group (7) is socketed on the column of tripod base its all regulatory functions.The structure of two hanging column groups is different variant because of the hanging sleeve position, purpose of design is: hanging column group (1) is to be socketed on the socket pile crown of rotary connector, hanging column group body is liftable not, so design allows its hanging column do lifting by cruciform joint, also can spin upside down, to increase adjustable range.Hanging column group (7) is to be enclosed within on the column of tripod base, hanging column group body can be on column lift adjustment, so design hanging column group (7) be fixed, with the increase stability.Two hanging column groups are sleeved on respectively on the different pile crowns and are not pind down mutually during for loading and unloading instrument in experiment.
Main folder mainly is made of clamp holder.The clamp holder of main folder is milled with straight trough, is located by connecting with main folder hole in the rotary connector, and matches with little key in the jack.The folder body is connected, presses by the elastic card of spring washer with clamp holder, so behind the main folder hand-hole, no matter where; The folder body rotates to any direction and all need not to fix separately, just is placed on duty.
Sub-folder, the folder body adopts screw to fix with being connected of clamp holder, therefore, except having conventional regulatory function, can also do 180 ° of adjustings of turning one's head.
Extension clamp, clamp holder has been attacked screw thread, matches with " T " font connector, is socketed on the adjustable hanging column group.
Simple and easy clip is for the multiple receiving vessel that needs in the clamping experiment, as conical flask etc.Clip is for the usefulness of clamping diameter less than 10 millimeters miniature instrument.
Hanger mainly is made of horizontal rod, hanger, pallet, gas washing rack for test tube.Hanger is socketed on (accessory of adjustable hanging column) on the horizontal rod, can rotate around column, and bottom puts and puts pallet, and in order to placing employed bottle Bottle ﹠ Can jar in the experiment, the gas washing rack for test tube is hooked on the cross bar of hanger, for the usefulness that inserts the gas washing test tube that needs in the experiment.It is flexible that hanger totally can be done translation along horizontal rod, can upper and lower lift adjustment, also can do 360 ° of rotations around column.
Column is on the tripod base, but column cooperates closely turn with base, desire is fixing then screw stop knob can.Asbestos rack frame is put and is put asbestos gauge on the platform iron ring.The "T"-shaped joint of cruciform joint is used to patch the horizontal rod of clip etc.Stator is used for fixing platform iron ring, horizontal rod etc.
Sample of the present utility model through practical probation prove a tool stand can be separately and very flexible, easily install existing just, various experimental provisions in the senior chemistry textbook, also be applicable to university chemistry basic course lecture experiment.The overall experimental provision of the contained seat of multipurpose chemical experimental stand or a certain local experimental provision can both be regulated by any space free in its activity scope, and can rotate demonstration; Adopt this practical stand to make lecture experiment, each student is observation experiment all sidedly, and all might obtain best observation place, use the utility model to compare with using former brandreth, each class demonstration can be saved time 1～2 minute to two, 30 minutes, the experimental provision complexity uses the utility model to feel convenient more, and it is many more to save time.
