Embodiment Construction

[0023] The handwheel (9) is adhered to the rotating shaft (6), and the three pairs of supports (14) on the upper part of the bushing (8) are respectively connected to the three claws (10) through pins (11), and the rotating shaft (6) passes through the lock nut (7) and the shaft sleeve (8), and the rotating shaft (6) can rotate freely in the lock nut (7) and the shaft sleeve (8), the notch-shaped protrusion (13) on the head of the rotating shaft (6) ) and the upper notch (12) of the quick-change joint (1) for circumferential positioning, the lock nut (7) is connected with the quick-change joint (1) through threads, and the rotating shaft (6) and the quick-change joint (1) Press it tightly for axial positioning. The quick-change joint (1) links to each other with the side bars (2) by pins (3), and the bars on both sides (2) link to each other with the two bottom bars (4) and between the two bottom bars by pins (5).

Abstract

The invention belongs to the field of biological experiment and chemical experiment equipment, in particular to an Erlenmeyer flask cleaner capable of rapidly replacing brush heads. It is mainly composed of a hand wheel, a rotating shaft, a side rod, a bottom rod, a quick change joint and a lock nut. The rotating shaft and the quick-change connector cooperate with the notch-shaped protrusion through the notch, and the threaded connection between the quick-change connector and the lock nut compresses the rotating shaft and the quick-change connector, which can realize quick replacement of the brush head to adapt to different types of Erlenmeyer flasks For cleaning, the three claws are evenly distributed on the outside of the shaft sleeve in the circumferential direction. When in use, the automatic centering function of the three claws can limit the rotating shaft of the conical flask cleaner to the central axis of the conical flask, so that the cleaning force is even. The invention can quickly clean the bottom and side of the conical flask at the same time, has the characteristics of good cleaning effect and high efficiency, and the brush head can be quickly replaced, and the brush head can be used for one device, saving resources.

Description

technical field [0001] The invention belongs to the field of biological experiment and chemical experiment equipment, in particular to an Erlenmeyer flask cleaner capable of rapidly replacing brush heads. technical background [0002] The Erlenmeyer flask is a glass vessel with a small mouth and a large bottom made of hard glass with a triangular longitudinal section. Commonly used are 50ml, 100ml, 200ml, 500ml, 1000ml, 2000ml and other different specifications, widely used in biological experiments and chemical experiments. [0003] At present, the cleaning tool of the Erlenmeyer flask is mainly a brush. A brush is made by twisting a wire and holding bristles. It is characterized by fewer bristles on the head, thinner and softer grip parts, and a straight rod structure. [0004] Due to the structural characteristics of the Erlenmeyer flask, the mouth is small, the cavity is large, and there are many specifications. It is relatively difficult to clean the bottom and sides...
