However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1 - Figure 8 An energy-saving boron nitride synthesis sintering furnace shown includes a furnace body 1, a cavity 2 is movably installed in the inner cavity of the furnace body 1, two frame-shaped support frames 3 are symmetrically arranged below the cavity 2, the bottom of the frame-shaped support frame 3 is fixedly connected to the inner wall of the furnace body 1, two slide bars 4 are symmetrically installed at the bottom of the cavity 2, the slide bars 4 correspond to the frame-shaped support frame 3, and the slide bars 4 are slidably installed on the surface of the frame-shaped support frame 3, the cavity 2 is movably installed inside the furnace body 1 through the slide bars 4 and the frame-shaped support frame 3, which is convenient for the installation of the cavity 2, and the cavity 2 can move inside the furnace body 1, which is convenient for the staff to perform daily maintenance operations on the cavity 2, and a pushing mechanism 6 is arranged on the top of the inner cavity of the furnace body 1, and a first rack 8 is fixedly arranged on the top of the cavity 2, and the first rack 8 cooperates with the pushing mechanism 6. Two expansion bins 5 are symmetrically arranged in the middle of the furnace body 1, a plane table 17 is arranged inside the expansion bin 5, a clamping and positioning mechanism 7 is arranged on the surface of the plane table 17, a sliding table 13 is slidably arranged at the bottom of the inner cavity of the furnace body 1, a third rack 24 is arranged on the side of the sliding table 13, the sliding table 13 cooperates with the clamping and positioning mechanism 7 through the third rack 24, and under the action of the pushing mechanism 6, half of the cavity 2 can be pushed to the outside of the furnace body 1, so as to facilitate the maintenance of the inside of the cavity 2 by the staff, and can remove the dust and dirt inside the cavity 2, and under the action of the clamping and positioning mechanism 7, when the cavity 2 is installed in the furnace body 1 or extended from the furnace body 1, the cavity 2 will be clamped to ensure the stability and safety of the cavity 2 during use.

[0026] The pushing mechanism 6 includes a first gear 10, which is arranged above the cavity 2, and the first rack 8 is meshed with the bottom of the first gear 10. A center rod 11 is arranged through the middle of the first gear 10, and the end of the center rod 11 is rotatably installed on the inner wall of the furnace body 1 through a rotating shaft. A second rack 9 is slidably arranged above the first gear 10, and the second rack 9 is meshed with the top of the first gear 10. The end of the second rack 9 is connected to a first pushing rod 12. When the first pushing rod 12 pulls the second rack 9, the first pushing rod 12 and the second rack 9 will move toward the rear of the furnace body 1 at the same time. Since the top and bottom of the first gear 10 are respectively meshed with the second rack 9 and the first rack 8, the first gear 10 will rotate clockwise during the backward movement of the second rack 9, and the first rack 8 will also drive the cavity 2 to move forward.

[0027] The sliding table 13 is located between the two frame-shaped support frames 3, and the end of the sliding table 13 is connected to the second pushing rod 16. The clamping and positioning mechanism 7 includes a second gear 14, and the second gear 14 is rotatably set on the surface of the plane table 17. The second gear 14 is set in the middle of the frame-shaped support frame 3, and the end of the second gear 14 passes through the frame-shaped support frame 3, so that when the sliding table 13 cooperates with the clamping and positioning mechanism 7, it will not be affected by the frame-shaped support frame 3. The third rack 24 is meshed with the second gear 14, and a clamping bar 15 is fixedly installed at one end of the top of the second gear 14. The end face of the clamping bar 15 is close to the outer surface of the cavity 2. When the second pushing rod 16 pulls the sliding table 13, the second pushing rod 16 and the sliding table 13 will move toward the rear of the furnace body 1 at the same time. At this time, the third rack 24 on the side of the sliding table 13 will drive the second gear 14 to rotate. When the second gear 14 rotates, the clamping bar 15 clamped on the outer surface of the cavity 2 will also rotate, and the clamping bar 15 does not apply an extrusion force to the cavity 2.

[0028] Both ends of the top of the clamping strip 15 are installed with protrusions 26, and the outer surface of the cavity 2 is provided with a groove 25, which corresponds to the protrusion 26, so that the clamping strip 15 has a better clamping effect on the cavity 2, ensuring the stability of the cavity 2 in the furnace body 1 and improving the work quality.

[0029] A cylinder 27 is installed on the back of the furnace body 1, and a connecting rod 28 is provided at the output end of the cylinder 27. An upper push rod 29 and a lower push rod 30 are respectively installed at the upper and lower ends of the connecting rod 28. The surfaces of the upper push rod 29 and the lower push rod 30 both penetrate the furnace body 1. The end of the upper push rod 29 is fixedly connected to the first push rod 12, and the size of the upper push rod 29 is the same as that of the first push rod 12. The end of the lower push rod 30 is fixedly connected to the second push rod 16, and the size of the lower push rod 30 is the same as that of the second push rod 16. When the output end of the cylinder 27 extends outward, the output end of the cylinder 27 will drive the connecting rod 28 to move toward the rear of the furnace body 1, and the connecting rod 28 will simultaneously drive the upper push rod 29 and the lower push rod 30 to move toward the rear of the furnace body 1. At this time, the upper push rod 29 and the lower push rod 30 will simultaneously pull the first push rod 12 and the second push rod 16, and the movement of the pushing mechanism 6 and the clamping and positioning mechanism 7 can be driven at the same time through the telescopic movement of the output end of the cylinder 27.

[0030] The surfaces of the upper push rod 29 and the lower push rod 30 are both installed with seals 31. When the output end of the cylinder 27 is contracted, the surface seals 31 of the upper push rod 29 and the lower push rod 30 will be tightly attached to the surface of the furnace body 1, ensuring the sealing of the furnace body 1 and the working quality of the furnace body 1.

[0031] A cross bar 18 is connected between the two frame-shaped support frames 3 located deep in the furnace body 1. A lifting column 19 is movably arranged inside the cross bar 18. A limiting groove 20 is arranged inside the cross bar 18. A limiting plate 21 is arranged in the middle of the lifting column 19. The surface of the limiting plate 21 is movably engaged in the limiting groove 20. A locking groove 22 is provided at the bottom of the cavity 2. The top of the lifting column 19 is engaged in the locking groove 22. A slope 23 is provided in the middle of the sliding table 13 and the second pushing rod 16. When the cavity 2 is fully installed in the furnace body 1, the sliding table 13 is moved at the slope 23. Under the action, the top of the lifting column 19 will be stuck in the fixing groove 22, so that the position of the cavity 2 can be positioned, and the horizontal height of the slope 23 gradually increases from the surface of the sliding table 13 to the surface of the second pushing rod 16. In the process of the second pushing rod 16 and the sliding table 13 moving toward the rear of the furnace body 1 at the same time, the horizontal height of the slope 23 directly below the lifting column 19 continues to decrease, so that the lifting column 19 will move downward under the action of its own gravity, and the top of the lifting column 19 will be detached from the fixing groove 22, which is convenient for the extraction of the cavity 2.

[0032] Working principle: First, when the output end of the cylinder 27 extends outward, the output end of the cylinder 27 will drive the connecting rod 28 to move toward the rear of the furnace body 1, and the connecting rod 28 will simultaneously drive the upper push rod 29 and the lower push rod 30 to move toward the rear of the furnace body 1. At this time, the upper push rod 29 and the lower push rod 30 will simultaneously pull the first push rod 12 and the second push rod 16. Then, when the first push rod 12 pulls the second rack 9, the first push rod 12 and the second rack 9 will simultaneously move toward the rear of the furnace body 1. Since the top and bottom of the first gear 10 are respectively engaged with the second rack 9 and the first rack 8, the first gear 10 will rotate clockwise during the backward movement of the second rack 9. With the cooperation of the first gear 10 and the first rack 8, the cavity 2 will move forward. At the same time, when the second push rod 16 pulls the sliding table 13, the second push rod 16 and the sliding table 13 will move to the rear of the furnace body 1 at the same time. At this time, the third rack 24 on the side of the sliding table 13 will drive the second gear 14 to rotate. When the second gear 14 rotates, the clamping strip 15 clamped on the outer surface of the cavity 2 will also rotate. The clamping strip 15 does not apply an extrusion force to the cavity 2. Under the push of the cylinder 27 and the pushing mechanism 6, the cavity 2 will move forward as a whole. Then, when one-half of the cavity 2 moves to the outside of the furnace body 1, the rear end of the first rack 8 engages with the first gear 10. After the second gear 14 rotates and rotates again, the other end of the clamping strip 15 will be clamped on the surface of the cavity 2. At the same time, the protrusion 26 on the other side will also be stuck in the groove 25 to achieve the clamping of the cavity 2, so that the cavity 2 has a higher stability after being extended, which is convenient for the staff to clean the inside of the cavity 2, and the maintenance of the cavity 2 is convenient for subsequent work.
