In order to solve the technical problems, the colorimetric tube for preventing the cap from falling comprises a colorimetric tube, wherein a fixing plug is clamped on the colorimetric tube, a fixing cap is fixed at the top of the fixing plug, a groove is formed in the surface of the colorimetric tube, and a column head is fixed at the top of the groove and positioned on the colorimetric tube;
The top of fixed cap is fixed with two solid fixed rings, and is provided with fixed rope on the solid fixed ring, be provided with two fixed slots with fixed rope looks adaptation on the fixed cap, just be located one side of fixed slot on the fixed cap and be fixed with first stopper, just be located the opposite side of fixed slot on the fixed cap and be fixed with the second stopper.
Preferably, the surface of the fixed plug and the inner wall of the colorimetric tube are both provided with frosting.
Preferably, the colorimetric tube is provided with a scale.
Preferably, the number of the column heads is six.
Preferably, the number of the first limiting blocks is four, and the number of the second limiting blocks is four.
Compared with the related art, the colorimetric tube for preventing the cap from falling off has the following advantages that
The beneficial effects are that:
the utility model provides a colorimetric tube for preventing a cap from falling, which is characterized in that two fixing ropes are respectively penetrated through two fixing ropes, the fixing ropes are clamped between a first limiting block and a second limiting block along a fixing groove on the fixing cap, two ends of the fixing ropes are respectively wound around a column head and a groove on the colorimetric tube and are bound and fixed, the colorimetric tube is heated, a fixing plug is prevented from falling off, and the problems that a cover of the existing colorimetric tube is simply clamped on the colorimetric tube, a firm fixing mechanism is lacked, the cover is unstable when a heating tube is heated, and the falling off risk is caused, so that the safety problem is caused are solved.
