Description

Technical Field

[0001] The utility model relates to the technical field of flask clip devices, in particular to a flask clip with self-locking, convenient use and detachable structure. Background Technique

[0002] Beaker clips are specifically designed for clamping heated beakers. Beaker clips are steel products plated with nickel and chromium on the surface, and the heads are sleeved with rubber tube sleeves. Clips for clamping round-bottom flasks are generally called flask clips, flask stands, and pliers. It usually consists of a clamping device and a bolt fixing device, and can clamp the flask on the laboratory stand for high-temperature heating tests or other chemical experiments. The clamping device of the flask clip generally adopts a spring or screw adjustment structure, which can flexibly adjust the tightness of clamping the bottle to ensure the stability and safety of the operation.

[0003] However, it still has some disadvantages. For example, during the process of chemical experiment operations, devices for fixing flasks are often used. The existing devices for fixing flasks mainly consist of an iron stand, a crosshead, and a flask clip. None of the three can be missing, and the assembly is rather troublesome and time-consuming, reducing the experimental efficiency. At the same time, the commonly used crosshead is fixed on the column by using double-notch screws. This fixing method of the crosshead makes the screw and the iron column in point contact and fit. If the screw is not tightened enough, or the screw and the iron column do not fit at a stable point, the connection will become loose. If the experimenter does not turn the notch at the end inserted into the experimental instrument upwards during use, it is easy to make the glass instrument unstable and fall, and then the chemical reagent will spill out, causing a greater potential safety hazard.

[0004] To solve the above problems, a flask clip with self-locking, convenient use and detachable structure is proposed in this application. Content of the Utility Model
