[0018] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0019] 1. In this invention, by setting up a gas distribution device, a motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel then drives a cam to rotate through a connecting block and a rotating plate. The cam rotates within a rectangular groove, causing it to press against the rectangular groove. This causes the rectangular groove to cause a connecting block to oscillate in a circular motion, which in turn causes the connecting block to oscillate the gas delivery pipe.

[0020] 2. In this invention, by setting a locking device, the closed cover door is closed, causing the locking block to move between the upper and lower support plates. Then, a bolt is inserted and tightened, causing the bolt to move the top sleeve downwards. This causes the top sleeve to press against the travel block, which in turn causes the travel block to slide in the transmission groove. This causes the transmission block to press the locking block to move to one side, so that the locking block causes the cover door to fit tightly against the furnace body, thereby improving the sealing performance.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6This invention provides a technical solution: a multi-channel gas distribution structure for a quartz furnace, including a furnace body 2 and a cover door 1. One side of the cover door 1 is attached to one side of the furnace body 2, and the cover door 1 is connected to the furnace body 2 via a hinge. A top groove 3 is provided on the top of the furnace body 2, and a gas distribution device 4 is provided on the top of the furnace body 2. The gas distribution device 4 includes a motor 405 and multiple second rotating grooves 418. Second rotating rods 416 are rotatably connected in the second rotating grooves 418, and two corresponding second rotating rods 416 are connected to each other. A support sleeve 415 is connected, and an air supply pipe 411 is driven within the support sleeve 415. A cam 410 is driven by the output shaft of a motor 405. A connecting block 419 is connected to the top of the air supply pipe 411, and a rectangular groove 413 is opened on the top of the connecting block 419. The cam 410 rotates in the rectangular groove 413, causing the air supply pipe 411 to swing. A worm gear 404 is connected to the output shaft of the motor 405, and multiple worm wheels 407 are threadedly connected to the outer wall of the worm gear 404. A connecting block 408 is connected to the bottom of the worm wheel 407, and a rotating... The moving plate 409 is connected at its bottom to the top of the cam 410. The protrusion of the cam 410 fits against the inner wall of the rectangular groove 413. Multiple second rotating grooves 418 are respectively opened on both sides of the top groove 3. The inner wall of the support sleeve 415 has two first rotating grooves 417, and a first rotating rod 414 is rotatably connected in the first rotating groove 417. An air supply pipe 411 is connected between the two first rotating rods 414. A metal telescopic pipe 412 is connected to the outer wall of the air supply pipe 411. The air distribution device 4 also includes a protective cover 401. The bottom of the 01 is connected to the top of the furnace body 2, and both sides of the furnace body 2 are connected to fixed plates 406. One side of the motor 405 is connected to one side of one of the fixed plates 406, and the other end of the worm gear 404 is rotatably connected to one side of the other fixed plate 406. The top of the protective cover 401 has multiple upper through grooves 402, and the inner wall of the upper through groove 402 is rotatably connected to the outer wall of the connecting block 408. One side of the protective cover 401 has multiple side through grooves 403, and one end of the metal telescopic tube 412 extends out of the protective cover 401 through the side through groove 403.

[0030] In a specific implementation, a gas distribution device 4 is provided. The output shaft of the motor 405 drives the worm gear 404 to rotate, which in turn drives multiple worm wheels 407 to rotate. The worm wheels 407 then drive the connecting block 408 to rotate, which in turn drives the rotating plate 409 to rotate. The rotating plate 409 drives the cam 410 to rotate. The cam 410 rotates within the rectangular groove 413, causing it to press against the side wall of the rectangular groove 413. This causes the rectangular groove 413 to drive the connecting block 419 to rotate circumferentially. The first rotating rod 414 rotates within the first rotating groove 417, and the second rotating rod 416 rotates within the second rotating groove 418. This causes the connecting block 419 to drive the gas delivery pipe 411 to swing, thereby increasing the gas delivery range of the gas delivery pipe 411. This improves the uniformity of the protective gas flow within the furnace body 2, thus ensuring the protective effect of the protective gas. By providing a metal telescopic pipe 412, the metal telescopic pipe 412 can withstand high temperatures, avoiding the influence of other materials that are not heat-resistant on the gas delivery effect.

[0031] A locking device 5 is connected to one side of the furnace body 2. The locking device 5 includes an upper support plate 503, a lower support plate 504, and a locking block 505. One side of the upper support plate 503 and one side of the lower support plate 504 are connected to one side of the outer wall of the furnace body 2, and one side of the locking block 505 is connected to one side of the cover door 1. The locking block 505 is located between the upper support plate 503 and the lower support plate 504. A stroke groove 507 is formed in the locking block 505, and transmission grooves 508 are formed on both sides of the inner wall of the stroke groove 507. A transmission block 509 is slidably connected inside 508, and a stroke block 510 is connected between the two transmission blocks 509. Both the upper support plate 503 and the stroke block 510 have through holes, and a nut 506 is embedded in the lower support plate 504. A bolt 502 is threaded into the nut 506. A top sleeve 501 is connected to the outer wall of the bolt 502, and the bottom of the bolt 502 passes through the through holes in the upper support plate 503 and the stroke block 510. The bottom of the top sleeve 501 abuts against the top of the stroke block 510.

[0032] In a specific implementation, by setting a locking device 5, the cover door 1 is closed. The movable wheels at the bottom of the cover door 1 make it easier to push the cover door 1, and the movable wheels support the cover door 1, preventing the cover door 1 from bending at the hinge due to its weight, which would affect the sealing effect of the cover door 1. The cover door 1 drives the locking block 505 to move between the upper support plate 503 and the lower support plate 504. Then, the bolt 502 is inserted, and the wrench is used to turn the bolt 502 into the nut 506. This causes the bolt 502 to drive the top sleeve 501 to move downward, so that the top sleeve 501 presses the stroke block 510. The stroke block 510 drives the transmission block 509 to slide in the transmission groove 508, which in turn causes the transmission block 509 to press the locking block 505 to move to one side. This makes the locking block 505 cause the cover door 1 to fit tightly against the furnace body 2, thereby improving the sealing performance.

[0033] Working principle: During use, when closing the cover door 1, pushing the cover door 1 causes the locking block 505 to move between the upper support plate 503 and the lower support plate 504. Then, the bolt 502 is inserted and tightened, causing the bolt 502 to move the top sleeve 501. This causes the top sleeve 501 to press down on the travel block 510, which in turn moves the transmission block 509. The transmission block 509 then moves the locking block 505 to one side, thus pulling the cover door 1 and ensuring a tight seal between the cover door 1 and one side of the furnace body 2. Subsequently, the motor 405 drives the worm gear 404 to rotate, which in turn drives the worm wheel 407 to rotate. The worm wheel 407 drives the connecting block 408 to rotate, which in turn drives the rotating plate 409 to rotate. This causes the rotating plate 409 to drive the cam 410 to rotate, which in turn causes the cam 410 to press against the rectangular groove 413. This causes the rectangular groove 413 to drive the connecting block 419 to oscillate in a circular motion. This causes the connecting block 419 to drive the gas conveying block to oscillate, thereby increasing the gas conveying range of the gas conveying pipe 411 and improving the uniformity of the protective gas flow in the furnace body 2, thus ensuring the protective effect of the protective gas.
