The present invention provides a kind of adjustable graphite crucible clamp with self-locking device, including left side arm, right arm, fixed pin, link block, pull rod, pawl, spring, ratchet, lock-screw, concentric reducer and operating stick.Left side arm, right arm are linked together with fixed pin, and the rear end of right arm is linked together by link block and pull rod, and ratchet mechanism is provided on pull rod, and the effect of lock-screw is to fix ratchet, prevent its rotation.The present invention is a kind of adjustable graphite crucible clamp with self-locking device, is suitble to the crucible of plurality of specifications；Pull rod is pushed and pulled to clamp crucible by operator, is not needed manually to apply grip to clamp crucible, is alleviated the labor intensity of operator；The features such as ratchet mechanism energy automatic locking pull rod, crucible are not easy to loosen, fall off, and crucible will not be overturned, can quickly and safely be taken out crucible from heating furnace by when taking-up.
Description
Technical field
The present invention relates to graphite product fields, more specifically to a kind of adjustable graphite crucible with self-locking device
Fixture.
Background technique
Traditional crucible clamp be it is scissor, fulcrum is in centre.Crucible is clamped with nose curvature；Hold rear end
Handle, when use, can apply two kinds of power, and a kind of to be inwardly used to clamp crucible or crucible cover, another kind is that crucible etc. is held upwards
It rises.Though this crucible purposes is wide, for single pair clamps crucible, all there is disadvantage in structure and force mechanism.It is applied and is held by hand
Power clamps crucible, increases the labor intensity of operator, if hand apply grip it is inadequate when, crucible takes off easily from crucible tongs
It falls, easily overturns crucible, be unfavorable for quickly smoothly takeing out crucible.
Summary of the invention
The present invention provides a kind of adjustable graphite crucible fixture with self-locking device in view of the deficiency of the prior art.
The invention adopts the following technical scheme:
A kind of adjustable graphite crucible clamp with self-locking device, including left side arm, right arm, link block, pull rod, ratchet
Mechanism and operating stick；The ratchet mechanism is arranged on pull rod；The middle-end of the left side arm and right arm is connected by fixed pin
It is connected together, the rear end end of the right arm is linked together by link block and pull rod；The left side arm and right side
Arm front is divided into arranged symmetrically, and respectively semi arch, the left side arm and right arm rear portion are divided into asymmetric setting.
The above-mentioned adjustable graphite crucible clamp with self-locking device, it is preferred that it further include lock screw, the locking spiral shell
Follow closely fixed ratchet wheel mechanism；The ratchet is with a thickness of 3mm.
The above-mentioned adjustable graphite crucible clamp with self-locking device, it is preferred that further include φ 15- φ 20mm concentric reducer.
In use, holding operating stick on the other hand, and pawl tail portion is gently pinned with thumb, so that pawl is detached from ratchet, while another
Pull rod to being pushed forward, is driven left and right side arm to open by one hand by link block；When pull rod pulls back, driven by link block left
Right arm is shunk, so that left side arm 1 and the front end semi arch portion retracts of right arm 2 be made to clamp crucible.After clamping crucible, spine
Mechanism automatic locking pull rod is taken turns, prevents pull rod from moving forward.As long as at this moment operator apply upward strength can steadyly incite somebody to action
Crucible end, which is risen, takes out.By replacement link block and pin hole, the size that adjustable left and right side arm opens, so as to adapt to difference
The crucible of specification.
Beneficial effects of the present invention are as follows: the configuration of the present invention is simple is skillfully constructed, using pull rod and ratchet mechanism by crucible
It clamps, does not need manually to apply grip to clamp crucible, alleviate the labor intensity of operator, and crucible is not easy to loosen, take off
It falls, the features such as crucible will not be overturned, can quickly and safely be taken out crucible from heating furnace by when taking-up.

Specific embodiment
For a further understanding of the present invention, the preferred embodiments of the invention are made below in conjunction with embodiment and comparative example
Further detailed description, but embodiments of the present invention are not limited to this.
Embodiment 1
A kind of adjustable graphite crucible clamp with self-locking device, including left side arm, right arm, link block, pull rod, ratchet
Mechanism and operating stick；The ratchet mechanism is arranged on pull rod；The middle-end of the left side arm and right arm is connected by fixed pin
It is connected together, the rear end end of the right arm is linked together by link block and pull rod；The left side arm and right side
Arm front is divided into arranged symmetrically, and respectively semi arch, the left side arm and right arm rear portion are divided into asymmetric setting.
The above-mentioned adjustable graphite crucible clamp with self-locking device, it is preferred that it further include lock screw, the locking spiral shell
Follow closely fixed ratchet wheel mechanism.
The above-mentioned adjustable graphite crucible clamp with self-locking device, it is preferred that further include φ 15- φ 20mm concentric reducer.
As shown in figures 1 to 6, a kind of adjustable graphite crucible clamp with self-locking device, structure include left side arm 1, right side
