Abstract

The utility model provides a test tube fixed, which is characterized by comprising a base, a stand column, a network ring and a test tube network; the stand column is vertically arranged on the base; a straight arm is arranged on the network ring; the front end of the straight arm is connected with the stand column in a slid fit way; the network ring is fastened with the stand column through a fastening screw; and the test tube network is installed on the network ring. A lantern ring in slide fit with the stand column is arranged at the front end of the straight arm on the network ring; a screw hole is arranged on the lantern ring wall; and the network ring is fastened with the stand column through the fastening screw and the lantern ring. Meshes on the test tube network are waved to be in different sizes according to sizes of test tubes; the test tube fixed mount has simple structure and low cost, is convenient and safe to use and can fix multiple test tubes for heating at the same time; and separation distance between the test tube and a heater can be regulated, and the work efficiency and the test consistency can be improved.

Description

A kind of test tube fixed mount

Technical field

The utility model belongs to the testing equipment technical field, is that the test tube fixture is used in a kind of laboratory specifically.

Background technology

At present in the laboratory usually with fixing test tube such as agrafe, rack for test tube, iron ring; Some basic experiments are arranged; Needing to be equipped with the test tube of reagent (reagent) heats after fixing again; At present common way has: the one, earlier with the fixing test tube of test tube clamp, with cotton rope etc. test tube clamp is fixed on above the heater together with test tube again; The 2nd, earlier, hand test tube clamp by the experimenter again and heat with the fixing test tube of test tube clamp; The 3rd, be placed on test tube fixedly and heat in the agrafe.The drawback of these three kinds of methods is: first method operates cumbersome, needs fixing twice; Second method is heated by the hand-held test tube clamp of experimenter, and operating efficiency is low, and danger coefficient is big; The third method is because fixing agrafe internal diameter big (generally being used for fixing flask, condensing reflux pipe etc.), and the diameter of test tube is all smaller, especially some more tiny low capacity test tubes is heated when testing, and test tube is difficult for fixation.

Summary of the invention

The utility model provides a kind of test tube fixed mount to the problems referred to above that prior art exists, and both easy and simple to handle, safety can conveniently heat the test tube fixation, and can heat simultaneously a plurality of test tubes again to test tube.

The purpose of the utility model realizes through following technical scheme:

A kind of test tube fixed mount is characterized in that comprising base, column, net ring, test tube net, and column vertically is set on the base; On the net ring straight-arm is arranged; The front end of straight-arm and column sliding connection make the net ring fastening with column with trip bolt, on the said net ring test tube net are installed.

A kind of improvement to technique scheme: the front end of straight-arm has the collar that is slidingly matched with column on the said net ring, on the cover ring wall screw hole is set, and the net ring is fastening through trip bolt and the collar and column.

Another kind to technique scheme improves: on the said column dovetail groove is set, the front end of straight-arm is the dovetail shaped that cooperates with said dovetail groove on the said net ring, on the said column screw hole is set, and the collar is connected and fixed by trip bolt and column.

A kind of improvement to technique scheme pilot scale pipe network: be evenly distributed with small through hole on the said net ring, cotton rope is weaved into said test tube net via small through hole, and described cotton rope is spring steel wire, iron wire or resistant to elevated temperatures cotton rope.

Another kind to technique scheme pilot scale pipe network improves: described test tube net is a wire netting, and described net ring is a becket, and the test tube net is welded on the net ring.

Further improvement to technique scheme: described net ring is circle, rectangle or polygon ring.

The advantage and the good effect of the utility model are:

The test tube fixed rack structure of the utility model is simple, cost is low, and is easy to use, safe, can fix a plurality of test tubes and heat simultaneously, and the spacing of test tube and heater can be regulated, and has improved the uniformity of operating efficiency and experiment.

Description of drawings

Fig. 1 is the user mode figure of a kind of test tube fixed mount of the utility model;

Fig. 2 is the structural representation of circular net ring in a kind of test tube fixed mount of the utility model.

The specific embodiment

Referring to Fig. 1, Fig. 2, the embodiment of a kind of test tube fixed mount of the utility model mainly is made up of base 1, column 2, net ring 3, test tube net 4; On the net ring 3 straight-arm 5 is arranged; There is the collar 6 that is slidingly matched with column the end of straight-arm 5, on the collar 6 trip bolt is arranged, and on the net ring 3 test tube net 4 is installed.Screw 7 is arranged on the wall of the described collar 6, and net ring 3 kinks are also fastening through screw 7 with trip bolt on column 2.Net ring 3 can be circle, rectangle or polygon ring, is evenly distributed with some small through hole 8 on the net ring 3, and cotton rope is weaved into test tube net 4 via small through hole 8.Cotton rope is resistant to elevated temperatures ropes such as spring steel wire, iron wire.Test tube net 4 also can be weaved into net earlier and be welded on the net ring 3 again, and the width of mesh of test tube net 4 can be weaved into different mesh sizes according to the concrete thickness of test tube.

Net ring 3 also can adopt the mode of being slidingly connected such as dovetail groove to be connected with column 2.As: on column 2, dovetail groove is set, the front end of straight-arm 5 is the dovetail shaped that cooperates with said dovetail groove on the said net ring 3, on the column 2 screw hole is set, and net ring 3 is fastening through trip bolt and column 2.

During use, earlier the collar on the straight-arm 56 is enclosed within on the column 2, adjusts height, and tighten trip bolt, locking net ring 3 height.With being housed, one of the reagent reagent or many test tubes are inserted in the netted hole of test tube net 4; Since the netted hole size less than the diameter of test tube in addition the netting twine rope have elasticity; Just can be fixed on test tube between the cotton rope firmly; On the base below the test tube 1, place heaters such as alcolhol burner, heating jacket, just can be simultaneously one or many test tubes be continued uniform heating.

Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of having done, remodeling, interpolation or replacement also should belong to the protection domain of the utility model.
