Abstract
The utility model provides a quick burette clamp, which comprises a fastening mechanism and at least one clamping mechanism. The fastening mechanism moves up and down along an upright rod of a burette stand and can be connected with the burette stand in a positioned manner, the clamping mechanisms used for clamping burettes are fixedly connected with the fastening mechanism, each clamping mechanism consists of a main body fixedly connected with the fastening mechanism, two clamp arms extending outwards and telescopic rods are arranged on each main body, the telescopic rods are movably connected with the clamp arms, racks are arranged on bodies of the telescopic rods and are in meshed transmission with driving wheels with handles, and the driving wheels are rotationally fixed onto the main bodies. Due to the technical scheme, the quick burette clamp overcomes shortcomings that when an existing product is used, one person cannot clamp a burette easily due to higher strength of a spring, the burette cannot ascend and descend conveniently, tightness of the burette cannot be controlled easily, the burette is unstable and cannot be taken conveniently, and the like. When the quick burette clamp is used during an experiment, one person can easily and safely clamp and detach a burette.
Description
Technical field
Laboratory apparatus field under the utility model, particularly a kind of novel buret clamp device.
Background technology
Titration is a kind of very important experimental implementation in the scientific research, and buret need be by fixture or clamps on titration stand in titration outfit, and existing fixture mainly takes modes such as butterfly clamp, spring clip, spiral clamp, magnet absorption is fixing that buret is fixed; These existing fixed modes mostly exist to go up and down inconvenient; The bad control of degree of tightness, instability, the deficiencies such as inconvenience of taking; And damage buret during regular job easily; Gently then cause experimental error, lose time, heavy then damage laboratory apparatus.
Have spring buret clamp product now in use, because the spring dynamics is bigger, a people is difficult to accomplish the clamping of buret.When people does experiment, must another person help could accomplish the safe clamping of buret, also need others to help when dismantling buret, it is very inconvenient to operate.
Summary of the invention
The problem that the utility model will solve provides the buret clamp of a kind of conveniently clamping and dismounting buret.Utilize lever principle,, reduce operation firmly, make experimenter conveniently clamping and dismounting buret through the teeth transmission.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of quick buret clamp; Comprise the retention mechanism (1) that moves up and down and can be located by connecting along the buret stand vertical rod, and at least one group of clamping device that is used for the clamping buret that is fixedly connected with retention mechanism (1), every group of clamping device comprises the main body (3) that is fixedly connected with retention mechanism; Main body is provided with overhanging two jig arm (2), and each jig arm top is provided with grip block; Main body also is provided with the expansion link (4) with its flexible connection, and the expansion link body of rod is provided with tooth-strip part, with the driving wheel that have handle (7) (6) engaged transmission of rotational fixation on main body.
Said expansion link is provided with female component (5) away from the end of main body, and the cross section of female component can be any one of V-type, U type or arc.
The part of the corresponding buret of said grip block can be provided with groove.
Said jig arm can be arc.
The material of said buret clamp can be plastics or macromolecular material.
Said main body (3), jig arm (2) adopt once injection moulding with retention mechanism (1), are integral structure.
Said retention mechanism (1) comprises tube connector and the nut of screwing that has mesopore, and tube connector top is connected with the nut of screwing through screw thread, and the tube connector bottom is fixedly connected with clamping device.
Advantage and the good effect that the utlity model has are: overcome existing product in use, because the spring dynamics is bigger, a people is difficult to accomplish the clamping of buret; And it is inconvenient to go up and down; The bad control of degree of tightness, instability, the deficiencies such as inconvenience of taking; When doing experiment, a people can accomplish light, safe clamping and dismounting buret.
