The specific embodiment

As shown in drawings, quick clamp device of large nozzle of zinc pot described in the utility model comprises pot body 2 and the giant 10 that is installed in pot body 2 front ends.Front end at pot body 2 is installed with giant sleeve pipe 15.As Fig. 5, shown in Figure 6, giant sleeve pipe 15 is a tubular body, and its inner chamber is gone into son with the zinc pot in the pot body 2 and is communicated with, and the front end of giant sleeve pipe 15 has external screw thread, and by the sleeve pipe platen 17 that has been threaded.The front opening of giant sleeve pipe 15 is inner small and outside big horn mouth, can make things convenient for the plug-in mounting of giant 10.As Fig. 7, sleeve pipe pressing plate 99 shown in Figure 8 be fixedly mounted on the front end of pot body 2, be pressed in giant sleeve pipe 15 above, play the fixedly effect of giant sleeve pipe 15.Be inserted into as Figure 11, giant 10 shown in Figure 12 in the horn mouth of front end of giant sleeve pipe 15.The rear end of giant 10 has the plug that the horn mouth with giant sleeve pipe 15 adapts, and this plug is inserted in the horn mouth of front end of giant sleeve pipe 15.Have external screw thread on the giant of plug front, and giant ring flange 6 is installed by this external screw thread.

Pot on giant sleeve pipe 15 is installed with baffle plate 19 on the body 2, baffle plate 19 an axle sleeve longitudinally each side is set, make it lay respectively at the both sides of giant 10.One axle center 20 respectively is installed in axle sleeve, and axle center 20 can be rotated in axle sleeve, and axle sleeve is stretched out at the two ends up and down in axle center 20.Shown in Figure 17,18, the top in axle center 20 has the square key of locating usefulness, and the side of hypomere has the key noise.The upper end in axle center 20 is by the fixedly connected

compressor arm

21,22 of going up of square key.As Figure 19-shown in Figure 21, the front end of

last compressor arm

21,22 has the corresponding keyway of square key with 20 tops, axle center, and is installed in the top in axle center 20 by this keyway, and axle center 20 can be rotated with last compressor arm 21,22.In this keyway, also be provided with bolt hole, be used for fixing to connect and go up

compressor arm

21,22 and axle center 20.The hypomere in axle center 20 passes through the fixedly connected compressor arm 24 down of keyway.As Figure 22, shown in Figure 23, following compressor arm 24 is a torus, its center has axis hole, be used for installing axle center 20, certainly, also be provided with keyway in the axis hole, when axle center 20 is installed in the axis hole, forward keyway on the axle center 20 and the keyway on the axis hole to same direction, in keyway, install flat key and promptly can compressor arm 24 can be rotated the fixed-site of axle center 20 and following compressor arm 24 with axle center 20.Have in a following side of compressor arm 24 and to compress pawl, compress pawl and be stuck on the giant ring flange 6.

Certainly,, and set up the boss of being convenient to catching, the pawl that compresses that presses down on the tight bar 24 directly is stuck on the giant 10 at its outer wall if suitably strengthen the diameter of giant 10.

Be connected with adjustable screw rod 25 between the last compressor arm 21,22.As Figure 28, shown in Figure 29, one end of screw rod 25 is a polished rod, the other end is threaded, the centre has the pin 27 of projection, and a threaded end is by the block 23 that has been threaded, as Figure 24-shown in Figure 27, block 23 is the triangle wedge shape, its center is threaded the hole, has internal thread in the screwed hole, can be installed in a threaded end on the screw rod 25.Polished end is set with the polished rod block, and the structure of polished rod block 26 and block 23 are similar, just do not have internal thread; The end of

last compressor arm

21,22 has screw hole, and have the triangle groove that the triangle wedge shape with block 23 and polished rod link stopper 26 adapts, the two ends of screw rod 25 are inserted into respectively in the screw hole, and for the ease of the end activity of screw rod 25 freely, this screw hole is designed to slotted hole.Block 23 and polished rod block 26 are positioned at the inboard of

compressor arm

21,22, make it can promote

compressor arm

21,22 when mobile laterally on screw rod 25 and rotate to both sides.

During use, giant sleeve pipe 15, sleeve pipe platen 17, baffle plate 19, axle center 20,

last compressor arm

21,22, following compressor arm 24, screw rod 25, block 23 and polished rod block 26 are in place successively.When giant 10 is installed, as long as giant 10 is inserted in the horn mouth of giant sleeve pipe 15 front ends, the pawl that compresses of following compressor arm 24 is stuck on the giant ring flange 6, with instrument rotary screw 25 block 23 is moved laterally, the

last compressor arm

21,22 that will promote both sides when block 23 is mobile laterally rotates to both sides,

last compressor arm

21,22 can drive down compressor arm 24 rotations again when rotating, thereby with 6 lockings of giant ring flange, giant 10 is inserted in the giant sleeve pipe 15 tightly.

In the time of dismounting giant 10,, giant 10 can be extracted out from giant sleeve pipe 15 as long as contra rotating screw 25 unclamps compressor arm 24 down.

The bell-mouthed cooperation can make its joint tightr between giant 10 and the giant sleeve pipe 15, avoid to remedy the wearing clearance that frequent dismounting causes automatically on the other hand because errors of processing technique causes leakage.But, the defective of relatively having required great effort when bell-mouthed cooperation has also brought dismounting, therefore, when dismounting giant 10, unclamp after the following compressor arm 24, if can not directly giant 10 be extracted out, can use instrument revoling tube platen 17, giant 10 will be ejected in the time of 17 rotations of sleeve pipe platen.

Certainly, in the utility model, can adopt multiple mode with being connected of screw rod 25 between the

last compressor arm

21,22, as long as can make

compressor arm

21,22 separately by rotary screw 25 to both sides.
