Description

Wire drawing crucible cover

Technical Field

The utility model relates to a crucible technical field, concretely relates to wire drawing crucible lid.

Background

The crucible is an important component of a chemical instrument, is a container for melting and refining metal liquid and heating and reacting solid and liquid, is a basis for ensuring smooth chemical reaction, has more specifications, is not limited by production scale, batch size and variety of melting substances when in application, can be selected at will, has stronger applicability, and can ensure the purity of the melted substances, and in the process of using the crucible, if the crucible needs to be heated by isolating air, the crucible cover needs to be used for sealing the crucible, but the traditional crucible cover and the handle are designed into an integrated structure, so that the surface temperature of the handle can be overhigh in the process of heating and melting the object, thereby causing the hands of workers to generate heat easily when the object is melted and the crucible cover needs to be detached, and further causing the hand scald accidentally when the object is seriously, the crucible cover is not easy to operate safely, so that a drawbench crucible cover is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a wire drawing crucible lid possesses and prevents to operate with the handle advantage such as serious that generates heat, has solved because the integrative design between traditional crucible lid and the handle to easily lead to the handle to generate heat and seriously be unfavorable for the problem of safe snatching the operation.

The utility model discloses a wire drawing crucible lid, including crucible lid main part, there is the flange crucible lid main part outside along annular integrated into one piece, the left and right sides at flange top all runs through and sets up and is equipped with the grab bar that is used for carrying out the operation to the crucible lid main part between first opening and two first openings, the first mica plate of the equal fixedly connected with in the left and right sides of first opening bottom, grab bar position in first open-ended inside and the outside leaves the clearance through between first opening and the flange, the left and right sides of grab bar surface all contacts along the bottom of annular fixedly connected with second mica plate and the top of flange, leave the space between the inboard top of grab bar and the top of crucible lid main part.

Through the design of the technical scheme, the grabbing rod can be kept in a near normal temperature state all the time, and the crucible cover main body or the convex plate is prevented from leading a large amount of heat into the surface of the grabbing rod to cause serious heating.

As a further design of the utility model, grab the surface of grabbing the pole and be close to the position department at second mica plate top along annular fixedly connected with becket.

Through the design of the technical scheme, the protection effect on the second mica plate can be realized, and the situation that the second mica plate is accidentally deformed when the grabbing rod is subjected to strong pressure is prevented.

As a further design of the utility model, the top of flange and the position department of being close to first opening top all set up the spacing groove that plays the joint restriction effect to two second mica plates respectively.

Through the design of the technical scheme, the limiting effect on the second mica plate can be realized, and the grabbing rod is prevented from contacting the convex plate through the first opening.

As a further design of the utility model, two the equal integrated into one piece in one side that the becket kept away from each other has the dead lever, the bottom fixedly connected with backup pad of dead lever, two the backup pad is located the left and right sides position department of crucible cover main part below respectively.

Through the design of the technical scheme, the crucible cover is more favorably placed, and the situation that the crucible cover main body is inconvenient to place due to overhigh surface temperature after being separated from a crucible after being used is prevented.

As a further design of the utility model, the surface of the grab bar is run through and is provided with a plurality of second openings.

Through the design of the technical scheme, the contact area between the grabbing rod and the outside air is effectively increased, so that the heat dissipation effect of the grabbing rod is better, meanwhile, the friction between the hand of a worker and the grabbing rod can be increased, and the grabbing operation of the grabbing rod by the worker is facilitated.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses, through will grabbing the pole and setting up in two first open-ended insides and leave gapped design between them, can effectually cover the main part to the crucible and grab and play the thermal-insulated effect of separation between the pole, prevent to grab direct contact between pole and the crucible cover main part, simultaneously, first mica plate and second mica plate can effectually play the heat effect of hindering heat to what crucible cover main part and flange were derived for grab the pole and can keep nearly normal atmospheric temperature state throughout, more favourable staff carries out safe operation to the crucible cover main part.

2. The utility model discloses, structural design through the spacing groove can realize the restriction effect to the second mica plate for the outside of grabbing the pole through first opening all the time and leave the clearance between the flange, prevent direct contact between first opening and the flange, through the structural design of becket, dead lever and backup pad, more be favorable to the staff to place the processing to this crucible cover after dismantling, prevent to dismantle the back to this crucible cover, because the too high condition that leads to placing inconvenience appears of surface temperature.
