Description
Technical field
The utility model relates to crucible tongs technical field, particularly relates to a kind of safety-type crucible tongs.
Background technology
Crucible tongs are a kind of fixtures for clamping, moving, overturn crucible, and conventional crucible tongs are for being scissor crucible tongs, and scissor crucible tongs are clamped crucible outer wall or clamped crucible inside and outside wall, use the grip in hand, crucible gripping from burner hearth is gone out.Existing crucible tongs material in crucible is heavier, crucible is also had at high temperature to come out of the stove (usually at this moment temperatures as high in Muffle furnace: about 1000 degree), crucible outer wall becomes fragile, at this moment the grip in hand controls very consummate, slightly carelessness or hand in grip apply improper, just can occur crucible topple even breakage etc. danger.Now conventional crucible is all big up and small down truncated cone-shaped structure, in order to prevent breaking, also a kind of C shape crucible tongs are had, comprise C shape split ring and handle, the inner radii of C shape split ring is between crucible bottom radius and crucible top radius, during use, C shape split ring is stuck in crucible from crucible lower end, then move up, when mobile, the radius of crucible constantly increases, when moving to crucible exterior radius and being equal with C shape split ring radius, both clampings, clamping, but there is opening portion due to C shape split ring, after clamping with crucible, at mobile crucible, when toppling over crucible, the angle that one suitable must be kept between the two, if time under the opening of C shape split ring is tilted to, then easily relatively rotate between crucible and crucible tongs when toppling over crucible, slide, thus cause potential safety hazard.
Utility model content
The utility model in order to overcome crucible tongs of the prior art clamping unstable, use unsafe deficiency, provide and a kind ofly clamp stability and safety, safety-type crucible tongs easy to use.
To achieve these goals, the utility model adopts following technical scheme:
A kind of safety-type crucible tongs, comprise C shape ring and handlebar, one end of described handlebar is fixedly connected with the center, periphery of C shape ring, the opening two ends of described C shape ring are respectively equipped with arc jig arm, the inner and the C shape ring of described arc jig arm are rotationally connected, the radius of a circle that the intrados of described arc jig arm is corresponding with the intrados of C shape ring is equal, the inner of described arc jig arm stretches out formation connecting rod, the outer end of connecting rod is provided with connecting ring, connecting ring is connected with steel strand wires, described handlebar is provided with slide block, the outer end of described steel strand wires is fixedly connected with slide block, the junction of described arc jig arm and C shape ring is provided with torsion spring.Slide block is stirred during use, slide block pulls steel strand wires, arc jig arm is opened under the pulling function of steel strand wires, again C shape ring is stuck on crucible, then slide block is unclamped, arc jig arm is retracted for clearance under the effect of torsion spring, then move up along crucible, until crucible external diameter and C shape ring minor diameter fit, this completes the clamping of crucible, location, then just can rotate, topple over crucible, because the openend of C shape ring is subject to the spacing of arc jig arm, therefore crucible is more stable with coordinating of C shape ring, during use, crucible not easily and between crucible tongs rotates, slippage, use safer.
As preferably, the outside of described C shape ring is also provided with U-shaped guide holder, and described handlebar is provided with retainer ring in its one end near C shape ring, and retainer ring is provided with two pilot holes, and described steel strand wires are fixedly connected with slide block through U-shaped guide holder, pilot hole successively.U-shaped guide holder, pilot hole are all carry out spacing, guide effect to steel strand wires.
As preferably, the outer end of described handlebar is provided with heat insulation handle, and described handlebar is provided with caging bolt, the position of described slide block between caging bolt and heat insulation handle, also be provided with back-moving spring between slide block and heat insulation handle, described slide block side is provided with driving lever.During use, four heat insulation handles of finger grip, thumb stirs driving lever, thus slide block is moved towards outer end pull steel strand wires, driving lever is unclamped after C shape ring snaps in crucible, slide block moves under the effect of back-moving spring, and fit with crucible outer wall in arc jig arm clamping inner side, spacing, very easy to use, safety.
As preferably, the outer end of described heat insulation handle is provided with link.Link is convenient to crucible tongs and is hung.
Therefore, the utility model has clamping stability and safety, beneficial effect easy to use.
Accompanying drawing explanation
Fig. 1 is a kind of view of the present utility model.
Fig. 2 is arc jig arm open mode schematic diagram in the utility model.
In figure: C shape ring 1, handlebar 2, heat insulation handle 3, link 30, arc jig arm 4, connecting rod 5, connecting ring 6, steel strand wires 7, slide block 8, U-shaped guide holder 9, retainer ring 10, pilot hole 11, caging bolt 12, back-moving spring 13, driving lever 14, crucible 15.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of safety-type crucible tongs as depicted in figs. 1 and 2, comprise C shape ring 1 and handlebar 2, the right-hand member of handlebar 2 is fixedly connected with the center, periphery of C shape ring 1, the outer end of handlebar 2 is provided with heat insulation handle 3, the outer end of heat insulation handle is provided with link 30, the opening two ends of C shape ring 1 are respectively equipped with arc jig arm 4, the inner and the C shape ring of arc jig arm are rotationally connected, the junction of arc jig arm and C shape ring is provided with torsion spring, two arc jig arm naturally come closer under the effect of torsion spring, the radius of a circle that the intrados of arc jig arm 4 is corresponding with the intrados of C shape ring 1 is equal, the intrados of C shape ring is major arc, the inner of arc jig arm 4 stretches out and forms connecting rod 5, the outer end of connecting rod is provided with connecting ring 6, connecting ring is connected with steel strand wires 7, handlebar is provided with slide block 8, the outside of C shape ring 1 is also provided with U-shaped guide holder 9, the right-hand member of handlebar 2 is provided with retainer ring 10, retainer ring is provided with two pilot holes 11, two steel strand wires 7 are respectively successively through U-shaped guide holder 9, pilot hole 11 is fixedly connected with slide block 8, handlebar 2 is provided with caging bolt 12, and the position of slide block 8 between caging bolt and heat insulation handle, is also provided with back-moving spring 13 between slide block and heat insulation handle, and slide block side is provided with driving lever 14.
By reference to the accompanying drawings, using method of the present utility model is as follows: before use, crucible tongs are in the state shown in Fig. 1, during use, four refer to grip heat insulation handle, thumb stirs slide block, slide block is moved to the left and pulls steel strand wires, two arc jig arm outer end under the pulling function of steel strand wires opens up into state as shown in Figure 2, again C shape ring is stuck in the lower end of crucible 15, then slide block is unclamped, arc jig arm is the state shown in retracted for clearance to Fig. 1 under the effect of torsion spring, now crucible is in C shape ring inside, move up along crucible, until crucible external diameter and C shape ring minor diameter fit, this completes the clamping of crucible, location, then just can rotate, topple over crucible, because the openend of C shape ring is subject to the spacing of arc jig arm, therefore crucible is more stable with coordinating of C shape ring, during use, crucible not easily and between crucible tongs rotates, slippage, use safer.Therefore, the utility model has clamping stability and safety, beneficial effect easy to use.
