Description

Reverse clamping crucible tongs

Technical Field

The utility model relates to a crucible tongs, in particular to a reverse clamping crucible tongs.

Background

The current conventional crucible tongs generally include a pair of clamp arm that alternately set up and the clamping part that the clamp arm front end formed and the clamping part that the clamp arm rear end formed to, mainly press from both sides the crucible through the strength of finger and wrist when using, hold the clamping part and inwards move relatively when exerting oneself and realize the centre gripping, the clamping part outwards moves relatively when loosening the power and loosens, and current this kind of structure mainly has following problem: on the one hand, the force of a user is too large, and the crucible is easy to crush when being clamped at high temperature; on the other hand, the force of the user is too small, so that the crucible slides off; on the other hand, when the long crucible tongs are required to be clamped from the high-temperature furnace, the long crucible tongs are large and heavy, the strength of a user is not well mastered, and the long crucible tongs are inconvenient to use.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a reverse crucible clamping pliers which is time-saving, labor-saving, reliable in clamping and convenient to operate and use.

In order to solve the technical problems, the reverse crucible holding forceps comprise two forceps arms hinged through a hinge shaft, the front sides of the hinge shafts of the two forceps arms form a holding part with a clamping opening, elastic pieces for enabling the holding parts of the two forceps arms to relax outwards under the condition of not being subjected to external force are arranged between the rear sides of the hinge shafts of the two forceps arms, meanwhile, the holding parts of the two forceps arms are closed, the tail ends of the two forceps arms form the holding parts, and the elastic pieces can be stressed and compressed through operation of the holding parts, so that the clamping opening of the holding parts is opened.

The elastic piece is a spring transversely arranged between the two clamp arms.

Limiting blocks are arranged on the inner sides of the two clamp arms, and the springs are arranged between the two limiting blocks.

The clamping part comprises two arc-shaped sections respectively connected to the two clamp arms and clamping plates connected to the arc-shaped sections, and a clamping opening is formed between the two clamping plates.

The inner side end face of the clamping plate is provided with saw teeth.

One of the forceps arms is provided with an anti-skid sleeve positioned at the grasping part.

The clamp arm comprises a long clamp arm and a short clamp arm, and the anti-slip sleeve is arranged on the long clamp arm.

After adopting foretell structure, through the articulated clamp arm of two mutual articulated and the articulated shaft rear side of two clamp arms that set up between be used for making the gripping portion of two clamp arms outwards relaxation under not receiving external force state, make the closed elastic component of clamping part of two clamp arms simultaneously, thereby the support effect of elastic support power has been utilized ingenious when pressing from both sides to get the crucible, thereby can make the clamping opening of elastic component atress compression messenger clamping part open through operating the gripping portion, the effect of finger and wrist has significantly reduced, press from both sides and get labour saving and time saving, need not worry too big or the undersize of forcing, not only effectively avoided pressing from both sides the garrulous problem of crucible because of the too big problem of user's dynamics and the too little problem that can make the crucible landing of user's dynamics when pressing from both sides, moreover the auxiliary support effect of elastic component can also make the dynamics of user can accurate control, and is convenient to use reliable.

FIG. 2 is a schematic view showing a closed state structure of the reverse holding crucible tongs of the present utility model.

Detailed Description

The reverse holding crucible tongs of the present utility model will be described in further detail with reference to the drawings and detailed description.

As shown in the drawing, the reverse clamping crucible tongs of the present utility model comprises two tongs arms 2 hinged by a hinge shaft 1, the front sides of the hinge shafts of the two tongs arms 2 (the left direction in fig. 1 is defined as the front side) form a clamping part 3 with a clamping opening, the clamping part 3 comprises two arc sections 7 respectively connected with the two tongs arms and clamping plates 8 connected with the arc sections, the clamping opening is formed between the two clamping plates, an elastic part 4 for enabling the clamping parts of the two tongs arms 2 to be outwards relaxed under the condition of not being subjected to external force is arranged between the rear sides of the hinge shafts of the two tongs arms 2 (the right Fang Fangwei in fig. 1 is defined as the rear side), the elastic part 4 can be a spring transversely arranged between the two tongs arms 2, the tail ends of the two tongs arms 2 form a clamping part 5, the clamping parts of the two clamp arms 2 are closed by the elastic force of the springs in a normal state, when the crucible is clamped, the clamping mouth of the clamping part can be opened by applying an inward acting force to the clamping parts 5 formed at the tail ends of the two clamp arms 2, and the crucible can be clamped by loosening hands (if necessary, the reliable clamping of the crucible can be realized by applying a small auxiliary acting force outwards after the clamping), so that the clamping operation can be realized by the reset capability of the springs in the clamping process in normal case, the reliable clamping of the crucible can be realized by applying a small operation force even if the auxiliary operation force is applied, the operation force of a user is reduced (the operation strength of fingers and wrists is reduced), the operation is time-saving and labor-saving, when the crucible is required to be put down, the clamping mouth of the clamping part is opened by applying an inward acting force to the clamping parts 5, and the elastic piece is stressed to be compressed at the moment, the crucible releasing operation can be completed.

Further, limiting blocks 6 are arranged on the inner sides of the two clamp arms 2, and springs are arranged between the two limiting blocks, so that the reliability of spring installation and the stability in the use process are guaranteed.

Still further, the inner end surface of the clamping plate 8 is provided with serrations 9, whereby the reliability of the clamping can be increased.

Still further, the arm 2 includes a long arm and a short arm, and the long arm is provided with an anti-slip cover 10 at the grip portion 5, thereby playing a role of anti-scalding and anti-slip.
