Abstract
The utility model relates to a kind of from clamping crucible tongs.A kind of from clamping crucible tongs, its structure comprises heat insulating anti-skidding pincers and holds head, tong arm, fulcrum, cylindrical shell, plunger, spring, it is characterized in that: described tong arm upper end is provided with heat insulating anti-skidding pincers and holds head, lower end is connected by cutting with scissors to retrain with plunger top, fulcrum is positioned at inside tong arm, plunger is positioned at cylindrical shell and moves vertically, and plunger base has step, has spring between plunger base step and cylinder body bottom.Clamp crucible by spring tension, reach and operate when hand-held space, position is little, and automatically can keep the object of crucible clamp position.
Description
Technical field
The utility model belongs to crucible operation tool field, is specifically related to a kind of from clamping crucible tongs.
Background technology
At present in each large enterprises, scientific research institutions, crucible tongs are a kind of equipment often used.In use at present, bar thick stick principle is often adopted.According to lever principle, the arm of force and power have irreconcilable contradiction, and when hand-held position can not be opened because operating space is limited, the use of lever crucible tongs is just limited to.And experimenter is when long-time artificial clamping crucible, the muscular fatigue that long-time firmly clamping crucible can cause, causes crucible and drops, the perils such as contents spillage.Therefore need that a kind of to be not only applicable to hand-held space, position little, and can from the crucible of clamping.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of from clamping crucible tongs, and this device keeps crucible clamp position by spring to slide block mechanism tension force.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of from clamping crucible tongs, its structure comprises heat insulating anti-skidding pincers and holds head, tong arm, fulcrum, cylindrical shell, plunger, spring, it is characterized in that: described tong arm upper end is provided with heat insulating anti-skidding pincers and holds head, lower end is connected by cutting with scissors to retrain with plunger top, fulcrum is positioned at inside tong arm, and plunger is positioned at cylindrical shell and moves vertically, and plunger base has step, there is spring between plunger base step and cylinder body bottom, clamp crucible by spring tension.
Design principle of the present utility model:
The utility model mainly improves the bar thick stick principle of traditional crucible tongs, adds a slider-crank mechanism, completes crucible tongs gripping arm opening and closing movement with slide block movement.Specifically, when plunger moves upward, by fulcrum 3 position-limiting action and separate bottom clamping limb, and due to the hinge constraint bottom pivot distance clamping limb near, plunger motion small part is apart from just clamping limb being opened greatly.When plunger moves downward, cylinder inboard wall is to the inside power of clamping limb one, and then clamping crucible.When crucible needs to clamp temporarily, the tension force that spring gives plunger downward all the time, and then ensure that crucible tongs can clamp crucible always.
The beneficial effects of the utility model:
Can be found out by above-mentioned principle design, the one that the utility model provides is simple from clamping crucible tongs structure, and maintenance is easily, practical.When long-time clamping crucible, spring tension clamping crucible can be adopted, avoid experimenter's firmly muscular fatigue of causing of clamping crucible for a long time.And only need to promote plunger a little and can discharge crucible, easy and simple to handle, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram from clamping crucible tongs of the utility model embodiment 1.In figure, 1 heat insulating anti-skidding pincers hold head, 2 tong arms, 3 fulcrums, 4 cylindrical shells, 5 plungers, 6 springs.
Detailed description of the invention
Embodiment 1
A kind of from clamping crucible tongs, its structure comprises that heat insulating anti-skidding pincers hold 1, tong arm 2, fulcrum 3, cylindrical shell 4, plunger 5, spring 6, it is characterized in that: described tong arm 2 upper end is provided with heat insulating anti-skidding pincers and holds 1, lower end is connected by cutting with scissors to retrain with plunger 5 top, fulcrum 3 is positioned at inside tong arm 2, and plunger 5 is positioned at cylindrical shell 4 and moves vertically, has step bottom plunger 5, there is spring 6 between bottom plunger 5 bottom stage and cylindrical shell 4, clamp crucible by spring tension.
The undeclared part related in the utility model is same as the prior art or adopt prior art to be realized.
