Abstract
A kind of heat-resisting safety protection clamp, be made up of two tong arm interconnections, two tong arm infalls are provided with bearing pin, are mounted with security protection curved surface respectively at two tong arm nose curvature, install be connected with return spring in two tong arm rear ends.High temperature resistant friction lining block is mounted with inside described security protection curved surface.The utility model can increase the contact area of heat-resisting safety protection clamp and heating vessel, and clamping is stablized more, safely, reliably, prevent landing, avoids scalding, and easily simple to operate, guarantees that experiment is normally carried out, applied range.
Description
Technical field
The utility model belongs to chemical experiment technical field of tools, is specifically related to a kind of heat-resisting safety protection clamp.
Background technology
Chemical laboratory commonly use crucible tongs to clamp crucible heating or from thermal source as taken, put crucible gas lamp, electric furnace, muffle furnace, alcolhol burner.Traditional crucible tongs are intersected by two stainless steel tong arms or two fire-retardant, dysoxidizable hard material bar tong arms to form, and near pincers, there is a sweep at sharp place, main by this sweep clamping crucible.There are following defects in this crucible tongs: one, crucible tongs mainly assign to clamp crucible by bend, and what form sweep is the hard material that two diameters are less, therefore little with crucible contact area, cause crucible tongs clamp crucible time poor stability, be unfavorable for operation; Its two, other heating vessel is as young in triangular flask tripe is large, with the easier landing of crucible tongs clamping, smashes sample, laboratory technician even may be caused injured.So crucible tongs are except clamping except crucible, be difficult to the heating vessel being applied to other again.
Summary of the invention
Technical problem to be solved in the utility model is: solve above-mentioned prior art Problems existing, and a kind of heat-resisting safety protection clamp is provided, increase the contact area of heat-resisting safety protection clamp and heating vessel, clamping is more stable, safe, reliable, prevent landing, avoid scalding, and easily simple to operate, guarantee that experiment is normally carried out, applied range.
The technical solution adopted in the utility model is:
A kind of heat-resisting safety protection clamp, be made up of two tong arm interconnections, two tong arm infalls are provided with bearing pin, are mounted with security protection curved surface respectively at two tong arm nose curvature, install be connected with return spring in two tong arm rear ends.
In technique scheme, inside described security protection curved surface, be mounted with high temperature resistant friction lining block.
The beneficial effects of the utility model:
1, security protection curved surface and heating vessel contact area enlarge markedly, and making heat-resisting safety protection clamp more stable, safer when clamping heating vessel, more reliable, effectively preventing the landing of heating vessel, avoiding scalding, ensured the safety of operator.
2, range of application expands, and heat-resisting safety protection clamp not only can be applicable to clamp the large heating vessel of the end osculum such as crucible, also can be applied to the large heating vessel in the young ends such as triangular flask.
The rear tong arm of 3, heat-resisting safety protection clamp installs return spring additional, makes its more convenient, safety when operating, and have the function automatically returning to former duty
4, length shortens compared with former crucible tongs, operation of being more convenient for.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1-tong arm, 2-bearing pin, 3-return spring, 4-sweep, 5-security protection curved surface.
Detailed description of the invention
See Fig. 1, heat-resisting safety protection clamp of the present utility model, is made up of two tong arm interconnections, and two tong arm infalls are provided with bearing pin, is mounted with security protection curved surface respectively at two tong arm nose curvature, installs be connected with return spring in two tong arm rear ends.
High temperature resistant friction lining block is mounted with inside above-mentioned security protection curved surface.
