Abstract
The utility model discloses an explosion-proofing protective sleeve for test tube heating in a laboratory. The explosion-proofing protective sleeve comprises a fixed outer sleeve and a movable inner sleeve, wherein two threaded holes are formed in the inner side wall of the fixed outer sleeve, a threaded rod is matched in the two threaded holes, one end of the threaded rod is bonded with a hemispherical rubber pad, the other end of the threaded rod is bonded with a rotary handle, two sliding grooves are also symmetrically formed in the inner side wall of the fixed outer sleeve, two rubber balls are bonded on the outer wall of the movable inner sleeve, and the rubber balls are arranged in the sliding grooves in a matching manner; when the explosion-proofing protective sleeve is used, a test tube is arranged inside the fixed outer sleeve in a sheathing manner, the threaded rod is adjusted to enable the rubber pad to act on the outer wall of the test tube for fixation, and then the movable inner sleeve is adjusted according to the length of the test tube, so that the whole test tube, except the bottom for the heating, is wrapped, when the test tube is broken due to proper heating, and a solution in the test tube only can flow down along the explosion-proofing protective sleeve without splashing, and therefore, the explosion-proofing protective sleeve can effectively protect workers and protect the laboratory environment.
Description
Technical field
The utility model relates to a kind of heating test-tube explosive-proof protector cover of use for laboratory.
Background technology
Laboratory is when carrying out chemical substance detection; conventionally can use test tube; and by heating and analyze being encapsulated in the liquid of test tube; in prior art, conventionally adopt test tube clamp to carry out test tube clamping; then heat; this class mode of heating; bad or heat when inhomogeneous in test tube material; can cause tube breaking; cause its inner spray solution of loading to come, laboratory environment is polluted, simultaneously the dangerous property of the heated liquid possibility of part; easily human body is damaged, so be not suitable for promoting the use of.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of heating test-tube explosive-proof protector cover of use for laboratory, and this device can be protected in to heating test-tube, avoids the solution in vitro loaded to cause damage to human body.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of heating test-tube explosive-proof protector cover of use for laboratory, comprise fixed jacket and movable inner sleeve, described fixed jacket and moving sleeve are, lower penetrating body, on the madial wall of described fixed jacket, take fixed jacket as symmetrical centre point, be symmetrically arranged with two screwed holes, in two screwed holes, be combined with threaded rod, threaded rod one end extends to fixed jacket outside, the other end is positioned at fixed jacket inside, it extends on the end face of that one end of fixed jacket inwall and is bonded with a hemispheric rubber blanket, it extends on that one end of fixed jacket outside and is bonded with a handle, on the madial wall of described fixed jacket, be also symmetrically arranged with two chutes, the sealing of chute bottom, top has opening, the outer wall gluing of described movable inner sleeve has two ball, ball is engaged in chute.
As preferred technical scheme, on the outer wall of described fixed jacket, be enclosed with skid resistant course, described skid resistant course is the surperficial rubber sleeve with antiskid particles.
As preferred technical scheme, the outer wall of described movable inner sleeve and the inwall of fixed jacket fit.
As preferred technical scheme, the diameter of described ball is not less than the width of chute.
The beneficial effects of the utility model are: during use, test tube sleeve is located to fixed jacket inside, by regulating threaded rod, rubber blanket is acted on test tube outer wall, play fixation, then according to the length of test tube, regulate movable inner sleeve, make that test tube is whole to be wrapped, can be for the bottom of heating to reserving, improper while causing tube breaking in heating, invisible spectro solution can only flow down along this device, and can not flash, do not come, this device has effectively been protected relevant staff, protected the environment in laboratory simultaneously, and simple to operate, simple in structure, be applicable to promoting the use of.
