Description

Ball-milling mouth connection structure

Technical Field

The utility model relates to a glass instrument technical field specifically is a ball mill mouth connection structure.

Background

Glassware occupies an important position in chemical laboratories. From a standard 24# ground flask to a custom set of small test sets, various ground and seals connect the various units of the instrument to enable it to function as a closed whole. Ball-milling is a common form of milling, which has three major advantages: firstly, the frosted sealing surface is spherical, so that a certain torsion is allowed to be carried out at the joint, and a large tolerance is provided for the combined installation of the glass instrument; in addition, the sealing surface is shorter, which provides convenience for occasions requiring shorter length-diameter ratio; finally, the sealing surface angle is small, thus allowing relatively large forces in the vertical direction, which is advantageous for mounting relatively heavy medium and large condenser tubes and the like.

Current laboratory is fixed for the clip with the fixed mode that is used for ball mill mouth junction usually, has that the leakproofness is poor, intensity is low, unstable problem, leads to the experiment circulation liquid seepage easily, the going on of the experiment of being not convenient for.

SUMMERY OF THE UTILITY MODEL

The utility model provides a ball mill mouth connection structure has solved the technical problem who proposes in the above-mentioned background art to the not enough of prior art.

In order to achieve the above object, the utility model provides a following technical scheme: a ball mill mouth connection structure comprising:

the ball milling device comprises a first glass tube, a ball milling part is arranged at the tail end of the first glass tube, a hole cover is arranged on the first glass tube in a sleeved mode, and internal threads are arranged inside the hole cover;

the front end of the second glass tube is provided with a groove grinding opening, the groove grinding opening is matched with the ball milling part, external threads are arranged on the periphery of the groove grinding opening, internal threads of the hole cover are matched with the external threads of the groove grinding opening, and the aperture of the through hole on the hole cover is smaller than the diameter of the ball milling part.

Preferably, a sealing gasket is further arranged in the open hole cover.

Compared with the prior art, the utility model provides a ball grinds mouth connection structure possesses following beneficial effect:

the utility model provides a ball-milling mouth connection structure sets up standard size's screw thread in the periphery of recess mill mouth, go into first glass pipe with the trompil lid cover, insert ball-milling portion in the recess mill mouth, again will open the handhole door and screw up with the recess mill mouth and realize threaded connection, through the cooperation of handhole door and seal gasket, make seal gasket support the shoulder of ball-milling portion and be connected with further enhancement ball-milling portion and recess mill mouth, realize the purpose that the high strength is sealed, thereby avoid the liquid seepage, the guarantee experiment normally goes on.
