The longitudinal section of the fixing ring is in a side-standing conical shape, the top of the conical shape and the part facing the through hole are in smooth arc shapes, and the two sides of the conical shape and the inner wall of the inner pipe are connected through smooth transition arc shapes or are integrally formed.
When in use, one end of the brush rod with the brush bristles extends into a small-neck and large-belly glass instrument such as a flask, a conical flask and the like; for convenience of description, a flask or a conical flask is used in the following description to represent all glass apparatuses having similar small neck and big belly shapes; as the brush rod further enters the flask, the front end of the brush rod contacts the bottom of the flask. The brush rod penetrates through a through hole in the middle of the positioner, namely the positioner is sleeved outside the brush rod, and the rocker and the handle at the top end of the brush rod can be fixedly connected with the brush rod or detachably connected with the brush rod, so that the handle, the rocker and the brush rod can penetrate through the through hole of the positioner in two modes; the positioner is made of soft materials, such as rubber, particularly silica gel, the through hole has strong scalability, and the rocker-handle can be designed into a proper size so as to pass through the through hole; of course, the handle can be designed to be suitable for use, and then the handle and the rocking bar can be designed to be detachable, or the rocking bar and the brush rod can be detachable.
Furthermore, when the front end of the brush rod is abutted to the bottom of the flask, the positioner is aligned to the flask opening, the inner tube of the positioner extends into the flask opening, and the outer tube of the positioner is sleeved outside the flask opening. At the moment, the positioner is sleeved on the flask opening, the brush rod is limited in the through hole of the fixing ring of the positioner, the positioner is made of soft materials, and the brush rod cannot directly contact with the flask opening edge and cannot damage the flask. The glass instrument cleaning person holds the neck of the flask and the positioner with one hand and quickly shakes the rocker with the other hand, so that the front end of the brush rod is provided with bristles to clean the inner wall of the flask, particularly the inner wall of a big-belly part. The brush rod is generally formed by winding iron wires or steel wires, most of the positions of the front end of the brush rod, namely most of the brush rod entering the flask, are provided with bristles, and the brush rod is not easy to directly touch the inner wall of the flask to cause the flask damage; the upper part of the brush rod and the contact part of the upper part of the brush rod and the edge of the flask opening are separated by a soft positioner, and the flask cannot be damaged. Therefore, the test tube brush of the embodiment can sufficiently and comprehensively brush glassware such as a flask, and cannot damage the glassware.
Furthermore, the bottom end of the brush rod is provided with a special-shaped brush;
the special-shaped brush comprises a deformation rod, bristles are arranged on the deformation rod, and one end of the deformation rod is connected with the bottom end of the brush rod through a hinge;
the deformation rod comprises a middle rod and a bottom rod; the two ends of the middle rod are respectively provided with a hinge and are respectively connected with the brush rod and the bottom rod, and the middle rod is designed in an inclined mode and forms an obtuse included angle with the brush rod; one end of the bottom rod is provided with a hinge and is connected with the middle rod, and the bottom rod and the middle rod form an acute included angle;
the hinge is a spring hinge.
It should be noted that the spring hinge adopts the conventional technology, the spring hinge allows two rod members connected with the spring hinge to swing in the same plane, the rod members include a brush rod, a middle rod and a bottom rod, and the two planes allowed by the two hinges at the two ends of the middle rod to swing coincide, i.e. the bottom rod, the middle rod and the brush rod can only swing in the same plane. When the rocker is rotated in the above manner to rotate the brush rod in the instrument for brushing, the middle rod and the bottom rod are driven by the brush rod to make circular motion.
Furthermore, the hinge is a spring hinge, namely the middle rod and the brush rod form an obtuse included angle, and when the middle rod is not acted by external force, the middle rod keeps the state of the obtuse included angle with the brush rod; the centrifugal force is generated when the brush rod rotates, or the intermediate rod is blocked by the inner wall of the flask, and the intermediate rod is kept in a certain posture in a force balance state under the combined action of various forces including the torsional force of the return spring, the centrifugal force of the brush rod, the reaction force of the inner wall of the flask, the friction force and the like. Meanwhile, in the process of rotating the rocker, an operator can press down or pull up the brush rod, so that the middle rod and the bottom rod are lowered or lifted, and the bristles on the brush rod can brush other positions of the inner wall of the big-belly part such as a flask or a conical flask.
Further, the brush rod is limited by the fixer fixing ring in a wide range, i.e. not rigidly, and the brush rod has a larger freedom of movement, so that the rotation axis of the brush rod is not fixed when the brush rod rotates, and when the bottom rod rotates at the bottom of the flask or the conical flask, the rotation axes of the brush rod, the middle rod and the bottom rod are difficult to coincide with the central axis of the instrument, i.e. the bottom rod can perform all-round brushing on the inner wall of the bottom of the instrument in an eccentric or similar manner.
[ example 2 ]
As shown in figures 3 and 4, on the basis of the above embodiments, the brush rod of the present embodiment is provided with a stop at the top, and a spring is arranged below the stop and surrounds the outside of the brush rod.
