Description

Technical Field

[0001] The utility model relates to the technical field of experimental appliances, and more specifically to a safety protection structure for an alcohol lamp used in pharmaceutical chemistry experiments. Background Art

[0002] The alcohol lamp is a commonly used instrument in chemical experiments. The existing alcohol lamp mainly consists of a lamp body and a wick, and the wick is inserted into a ceramic ring, and the ceramic ring is placed at the opening of the alcohol lamp. When adding fuel, the ceramic ring can be taken out to expose the opening of the lamp body for adding.

[0003] However, the existing alcohol lamp lacks a positioning mechanism. When in use, it is directly placed on the desktop and is prone to tipping over when subjected to external forces. After tipping over, the fuel inside the lamp body will leak, causing safety accidents. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a safety protection structure for an alcohol lamp used in pharmaceutical chemistry experiments to solve the problems existing in the above-mentioned background art.

A ceramic ring is placed on the upper surface of the lamp body, and a hemp rope is embedded inside the ceramic ring. A suction cup is fixedly connected to the lower surface of the positioning base, a connecting pipe is fixedly connected to the upper surface of the suction cup, a mounting hole is opened on the upper surface of the positioning base, and the surface of the connecting pipe is fixedly connected to the inner wall of the mounting hole. A sleeve is fixedly connected to the upper surface of the positioning base, and the surface of the connecting pipe is fixedly connected to the inner wall of the sleeve. A threaded pipe is threadedly connected to the surface of the sleeve, a turntable is rotatably connected to the inner top wall of the threaded pipe, a T-shaped sealing plug is fixedly connected to the lower surface of the turntable, and the lower surface of the T-shaped sealing plug abuts against the upper surface of the connecting pipe. A ventilation hole is opened on the surface of the threaded pipe. The lamp body is detachably installed on the upper surface of the positioning base, and the suction cup adsorbs the desktop, which can ensure the stable placement of the lamp body.

[0006] Further, a circular groove is opened on the upper surface of the positioning base, a circular mounting seat is fixedly connected to the lower surface of the lamp body, and the surface of the circular mounting seat abuts against the inner wall of the circular groove. A T-shaped groove is opened on the inner wall of the circular groove, a T-shaped plug is slidably connected to the inner wall of the T-shaped groove, a first spring is fixedly connected to the opposite surfaces of the T-shaped plug and the T-shaped groove. The upper surface and the lower surface of the T-shaped plug are both arc-shaped, and a positioning groove adapted to the T-shaped plug is opened on the surface of the circular mounting seat. The surface of the T-shaped plug abuts against the inner wall of the positioning groove. The setting of the T-shaped plug and the first spring facilitates the disassembly and assembly of the lamp body on the positioning base.

[0007] Further, an installation ring is fixedly connected to the surface of the ceramic ring, and a connecting sleeve is fixedly connected to the surface of the installation ring. A fixing ring is fixedly connected to the surface of the top of the lamp body. The surface of the fixing ring abuts against the inner wall of the connecting sleeve. A T-shaped sliding groove is formed in the surface of the fixing ring, and a T-shaped inserting rod is slidably connected to the inner wall of the T-shaped sliding groove. A second spring is fixedly connected to the opposite surfaces of the T-shaped inserting rod and the T-shaped sliding groove. The end face of the T-shaped inserting rod is arc-shaped, and a hemispherical groove is formed in the inner wall of the connecting sleeve. The surface of the T-shaped inserting rod abuts against the inner wall of the hemispherical groove. Through the T-shaped inserting rod and the second spring, the connecting sleeve can be connected to the fixing ring, preventing the ceramic ring from directly falling off the lamp body.

[0008] The technical effects and advantages of the present utility model are as follows:

[0009] 1. For the safety protection structure of the alcohol lamp used in pharmaceutical chemistry experiments, rotate the threaded pipe, and the threaded pipe drives the T-shaped sealing plug to disengage from the connecting pipe. At this time, press the positioning base tightly against the tabletop, and the gas in the suction cup is discharged through the vent holes on the connecting pipe and the threaded pipe. After the suction cup is completely pressed against the tabletop, reverse the threaded pipe, and the threaded pipe drives the T-shaped sealing plug to press tightly against the connecting pipe to seal the connecting pipe. At this time, the suction cup sucks tightly against the tabletop, which can ensure the stable placement of the alcohol lamp on the tabletop and prevent it from being knocked over.

[0010] 2. For the safety protection structure of the alcohol lamp used in pharmaceutical chemistry experiments, place the circular mounting seat in the circular groove. At this time, the upper arc surface of the T-shaped insertion block is stressed and received in the T-shaped groove. Then rotate the circular mounting seat. When the positioning groove moves to the position of the T-shaped insertion block, the elastic force of the first spring pushes the T-shaped insertion block into the positioning groove, facilitating the disassembly and assembly of the lamp body on the positioning base.

[0011] 3. For the safety protection structure of the alcohol lamp used in pharmaceutical chemistry experiments, rotate the installation ring, and the installation ring drives the connecting sleeve to rotate. At this time, the arc surface of the T-shaped insertion rod is stressed and received, and the second spring is compressed. The T-shaped insertion rod moves out of the hemispherical groove, and the ceramic ring can be removed, facilitating the addition of fuel in the lamp body. When the fuel is not added, at this time, the T-shaped insertion rod is inserted into the hemispherical groove under the elastic force of the second spring, which can prevent the direct detachment of the ceramic ring after the lamp body is tilted and avoid fuel leakage.
