Abstract
The utility model discloses sample tongs with rotatable clamping parts. The sample tongs are provided with handles, tong arms and the clamping parts which are formed by the fact that a pair of tong bodies which are symmetrical in shape are connected through a hinge pin. The clamping parts and the tong arms are connected through hinge pins. The sample tongs with the rotatable clamping parts further comprise a driving mechanism which is connected with the clamping parts and can enable the clamping parts to rotate. The driving mechanism is pull rods which are connected with one side or two sides of the clamping parts through the hinge pins, or motors which are connected with one side or two sides of the clamping parts through a pair of gears and hinge pins which are mutually meshed. The sample tongs with the rotatable clamping parts can be turned over by clamping objects in an area with narrow space or in the sample forging process, the sample tongs are used, different requirements will be met in metallurgical industry production and experiments, and great convenience is brought about for the production and the experiments.
Description
Technical field
The utility model relates to a kind of laboratory or on-the-spot use clamping device, when relating in particular to heating vessel such as a kind of crucible that in the laboratory, is used for the various appearance and sizes of clamping in high-temperature heater or on-the-spot forging metal piece for the rotatable assay pliers of clamping part of clamping metal derby.
Background technology
Assay pliers is a kind of instrument for cold and hot samples such as heating vessels such as clamping crucible or metal derbies.At present, the kind of test pincers is a lot, generally has following characteristics: have long handle, curved surface or plane that the front end of long handle has jaw or matches with the gripped object shape.In use, a kind of mode is to use the sheet segment of jaw gripping sidewall of crucible or test button, and another kind of mode is to use curved surface or planar section clamping or holder to get crucible or metal derby body part.
At present, existing assay pliers all is that clamping, holder are got, heating vessel such as mobile crucible or clamping when forging, moving metal piece, and can't realize the function with the gripped object upset, especially in the narrow and small burner hearth in spaces such as vertical tube furnace.In iron and steel metallurgical industry, some production or laboratory experiment, for satisfy to produce, requirement of experiment, heated material must be overturn, and utilize present existing assay pliers, in the narrow and small burner hearth or space in space, very difficult realization maybe can't realize.
China's utility model patent " novel crucible tongs " (publication number CN 102078829 A) discloses a kind of crucible tongs that use in the laboratory.These crucible tongs mainly comprise: a pair of caliper of symmetry connects and composes by bearing pin mutually, and the termination of crucible tongs clamping part is the arc of fitting with the crucible outer surface.This crucible tongs retained part and caliper can't rotate for fixedlying connected, and realize the upset of heating vessels such as crucible by the whole upset of crucible tongs but be used in the horizontal pipe heating furnace, but can't be used for vertical tubular heater.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, convenient and practical, rotatable assay pliers of retained part, overcome existing assay pliers retained part and the fixed shortcoming that is connected of being connected to of caliper, especially can make gripped object realize overturning in the time of can or forging sample in narrow and small zone, space, utilize this assay pliers, in metallurgy industry production, experiment, will satisfy different requirements, and give and produce, test and bring great convenience.
The utility model is achieved by following technical proposals:
The rotatable assay pliers of a kind of clamping part: the handle, tong arm and the clamping part that have the caliper of a pair of shape symmetry to be formed by connecting by bearing pin; It is characterized in that: clamping part is connected by bearing pin with tong arm, also comprises being connected the driving mechanism that can make the clamping part rotation with clamping part.
Described driving mechanism is the pull bar that is connected by bearing pin with the clamping part one or both sides;
Or described driving mechanism is the motor that is connected with bearing pin with a pair of gear of clamping part one or both sides by mutual interlock;
Described assay pliers handle, its profile are quadrangle or the circles of a pair of shape symmetry, and wherein a side is bigger, and opposite side is less relatively;
The purpose of this design: meet the staff structure and have directionality.Assay pliers should be the side that thumb is held in little shape in use, and other four fingers are held in a side of big shape, and the another hand is handled rotating mechanism in a side of little shape.
Described assay pliers clamping part, the shape that its profile is complementary for the profile with gripped object, and one deck asbestos are cohered in the clamping part inboard;
The purpose of this design: the profile of clamping part profile and gripped object is complementary, and the way of contact of the two is face contact like this, makes clamping more firm, and can avoid the two to make the gripped object fragmentation because of a contact or line contact when the clamping brittle body.One deck asbestos are cohered in the clamping part inboard, can make the contact of the two play certain cushioning effect, assay pliers more is applicable in hot environment uses, and can avoid the high temperature vessel to burst because directly contacting cold caliper chilling.
At present, the assay pliers structure of using in metallurgy industry is single, retained part is connected with being connected to of tong arm is fixed, retained part can not rotate, therefore assay pliers can not make gripped object realize upset, especially in narrow and small zone, space, therefore exist and to satisfy production, experimental requirements.If can design a kind of simple in structure, convenient and practical assay pliers, especially can make gripped object realize the assay pliers that overturns in the time of can or forging sample in narrow and small zone, space, different production, requirement of experiment will be satisfied, give and produce, test and bring great convenience, reduce production, experimental cost greatly, create remarkable economic efficiency and social benefit.
