The invention discloses a surface treatment device for the internal thread of a building reinforcement sleeve, which comprises a base, an outer container is fixedly connected to the upper surface of the base, an inner container is fixedly connected to the inside of the outer container, and an outer container of the outer container of the base is fixedly connected. The surface is threadedly connected with multiple clamping mechanisms extending to the interior of the inner container. The multiple clamping mechanisms are located at one end of the inner container and are fixedly connected with a soft bucket. tube, and the upper end of the inner container is fixedly connected with a cylindrical cover tube. The surface treatment device for the internal thread of the building reinforcement sleeve proposed by the present invention is convenient to heat and keep warm the phosphating solution flowing into the horizontal electric furnace from the drain pipe by arranging a horizontal electric furnace under the base, so that its temperature can be kept at 85±5℃, by setting the liquid intake port, it is convenient to take the liquid next time for phosphating treatment, so that the device has the effect of recycling the phosphating solution and forms a cyclic phosphating system.

The invention relates to the field of experiment teaching, in particular to a dropper. The dropper comprises a cutting sleeve, a rubber head, a dropper body, a suction nozzle, a placement groove, a quantitative cap and a limiting piston. The cutting sleeve is arranged on the top of the rubber head. The bottom of the rubber head is connected with one port of the dropper body, and the other port of the dropper body is connected with the suction nozzle. The dropper body is composed of two arc glass sheets and two elastic sliding rails. The arc glass sheets and the elastic sliding rails are arranged in a spaced mode and connected in sequence to form the cylindrical dropper body. The limiting piston is arranged inside the dropper body. The outer diameter of the limiting piston is equal to the inner diameter of the dropper body. Scale marks are engraved in the arc glass sheets in the axial direction of the dropper body, and a plurality of clamping lock pieces are arranged on the elastic sliding rails; the placement groove and the quantitative cap are arranged at the upper portion of the dropper body; the plane where a notch of the placement groove is located is perpendicular to the dropper body and faces the suction nozzle; the quantitative cap is installed inside the placement groove. The dropper can achieve convenient quantitative liquid sampling, can lower the probability that fingers of a person are corroded by corrosive liquid, and is safe and practical.

The invention discloses a puncturing and liquid extracting mechanism. The puncturing and liquid extracting mechanism comprises a puncturing mechanism and a pipette, wherein the puncturing mechanism is arranged above an opening of a liquid storage tank; the upper part of the pipette sleeves the opening of the liquid storage tank, and the lower part of the pipette is inserted into the liquid storage tank and extends to the bottom of the liquid storage tank; the puncturing mechanism comprises a puncturing pipe, a blocking head, a liquid discharge mechanism and a linear driving mechanism, wherein the blocking head is connected with the linear driving mechanism; the lower end of the puncturing pipe penetrates through the blocking head; the blocking head drives the puncturing pipe to be inserted into a central hole of the pipette and is communicated with the pipette to form a seal structure; the blocking head and the upper part of the pipette are sealed. According to the invention, the puncturing mechanism and the pipette are matched, and after the puncturing pipe and the pipette are communicated, a liquid in the liquid storage tank can be pressed into the pipette by the liquid discharge mechanism and is discharged via the puncturing pipe; the discharged liquid amount is automatically controlled by operators according to the actual situation, so that the requirements of operators can be met well; moreover, liquid extraction is convenient and rapid.
