Abstract
A pair of tongs holding high-temperature crucible from inside belongs to the technical field of metal smelting tools and is used for holding a high-temperature crucible from inside. The utility model adopts the technical scheme as follows: the tongs include handles, a pin shaft, clamp heads and a spring. On each side, the handle and the clamp head are integrated, and the joint part of the handle and the clamp is bent inwards. The buckling joint parts of the handles and the clamp heads on two sides are overlapped, the pin shaft is arranged in the overlapping position, and the spring is mounted between the handles on the two sides. In the tongs adopting the structure, when in use, the handles on the two sides can be folded inwards, and the clamp heads on the two sides extend outwards simultaneously, so that the high-temperature crucible can be held from the inside of the high-temperature crucible. Therefore, the pair of tongs avoids the inconvenience that handles of the traditional crucible need to be opened outwards when the crucible needs to be held from inside, and is more convenient, labor-saving, safer and more reliable.
Description
Technical field
The utility model relates to a kind of high-temperature crucibles pincers, belongs to crucible operation tool technical field.
Background technology
Crucible is that enterprise, scientific research institution are engaged in the equipment that often uses in various material smeltings and melt production, the scientific research.In use, because high temperature need be gone into stove and the operation of coming out of the stove with crucible tongs clamping crucible.Crucible tongs generally all are to carry out clamping from the crucible outside now, are useful for Muffle furnace.Then impracticable to high temperature process furnances, the internal diameter of tube furnace and the crest clearance of crucible are little, therefore need the operation that a kind of crucible tongs are gone into stove and come out of the stove from the inboard clamping crucible of crucible.
Summary of the invention
The utility model technical issues that need to address provide a kind of can be more fixedly crucible, convenient and strength-saving, safe and reliable high-temperature crucibles pincers from inboard clamping crucible.
The technical scheme that solves the problems of the technologies described above is:
A kind of high-temperature crucibles pincers from inboard clamping crucible, it is made up of handle, bearing pin, chuck and spring, its improvements are, the handle of each side and chuck are an overall structure, the joint portion of handle and chuck bends inwards, the bending joint portion of the handle of both sides and chuck is overlapping, and bearing pin is installed in overlapping, and spring is installed between two side handles.
After the utility model adopts this structure, two side handles inwardly close up in use, the both sides chuck is outwards expansion simultaneously, outwards clamp crucible from the inboard of high-temperature crucibles, just can avoid using existing crucible tongs outwards to open the inconvenience of handle need be the time like this from inboard clamping crucible, convenient laborsaving, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: handle 1,4, bearing pin 3, chuck 2,6, spring 7.
The specific embodiment
Show among the figure that the utility model is made up of handle 1,4, bearing pin 3, chuck 2,6 and spring 7.
Show among the figure that the handle 1 of a side and chuck 2 are an overall structure, the handle 4 of opposite side and chuck 6 also are an overall structure, and bearing pin 3 is installed in the joint portion of two side handles 1,4 and chuck 2,6, and spring 7 is installed between two side handles 1,4.Adopt such structure, method of clamping and general crucible tongs are very different: when general crucible tongs inwardly closed up at handle, chuck also inwardly closed up, the outside of clamping crucible; And the handle of the utility model in both sides be when inwardly closing up, and chuck will outwards open, in order to the inboard of outside clamping crucible.
When using the utility model, both hands or one hand are held handle 1,4, and chuck 2,6 is extend into high-temperature crucibles inside, and the handle 1,4 of holding with a firm grip then proposes crucible, last release handle 1,4, and spring 7 will make crucible tongs restore to the original state.Can be more fixing crucible, convenient and strength-saving, safe and reliable.
