DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0024] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0025] As Figure 1 - Figure 8 shown, an energy-saving boron nitride synthesis and sintering furnace includes a furnace body 1. A cavity 2 is movably installed in the inner cavity of the furnace body 1. Two frame-shaped support brackets 3 are symmetrically arranged below the cavity 2. The bottom of the frame-shaped support bracket 3 is fixedly connected to the inner wall of the furnace body 1. Two sliding bars 4 are symmetrically installed at the bottom of the cavity 2. The sliding bars 4 correspond to the frame-shaped support brackets 3, and the sliding bars 4 are slidably installed on the surface of the frame-shaped support brackets 3. The cavity 2 is movably installed in the furnace body 1 through the sliding bars 4 and the frame-shaped support brackets 3, which is convenient for the installation of the cavity 2. 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. A pushing mechanism 6 is arranged at the top in the inner cavity of the furnace body 1. A first rack 8 is fixedly arranged at the top of the cavity 2. The first rack 8 cooperates with the pushing mechanism 6. Two expansion chambers 5 are symmetrically arranged in the middle of the furnace body 1. A flat table 17 is arranged inside the expansion chamber 5. A clamping and positioning mechanism 7 is arranged on the surface of the flat table 17. A sliding table 13 is slidably arranged at the bottom in 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. 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 staff to maintain the inside of the cavity 2, and the dust and dirt inside the cavity 2 can be removed. And under the action of the clamping and positioning mechanism 7, when the cavity 2 is installed in the furnace body 1 or extends out of the furnace body 1, the cavity 2 will be clamped, ensuring the stability and safety of the cavity 2 during use.

[0026] The pushing mechanism 6 includes a first gear 10. The first gear 10 is arranged above the cavity 2. The first rack 8 meshes with the bottom of the first gear 10. A central rod 11 is arranged through the middle of the first gear 10. The end of the central 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. The second rack 9 meshes with the top of the first gear 10. The end of the second rack 9 is connected to a first push rod 12. When the first push rod 12 pulls the second rack 9, the first push rod 12 and the second rack 9 will move backward to the rear of the furnace body 1 at the same time. Since the top and bottom of the first gear 10 mesh with the second rack 9 and the first rack 8 respectively, during the backward movement of the second rack 9, the first gear 10 will rotate clockwise, and at the same time, the first rack 8 will also drive the cavity 2 to move forward.

[0027] The sliding table 13 is located between two frame-shaped support brackets 3. A second push rod 16 is connected to the end of the sliding table 13. The clamping and positioning mechanism 7 includes a second gear 14. The second gear 14 is rotatably arranged on the surface of the flat table 17. The second gear 14 is arranged in the middle of the frame-shaped support bracket 3, and the end of the second gear 14 passes through the frame-shaped support bracket 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 bracket 3. The third rack 24 meshes with the second gear 14. One end at the top of the second gear 14 is fixedly installed with a clamping strip 15. The end face of the clamping strip 15 is close to the outer surface of the cavity 2. When the second push rod 16 pulls the sliding table 13, the second push rod 16 and the sliding table 13 will move backward 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. After the second gear 14 rotates, the clamping strip 15 clamped on the outer surface of the cavity 2 will also rotate, and the clamping strip 15 will not apply extrusion pressure to the cavity 2.

[0028] Both ends at the top of the clamping strip 15 are installed with protrusions 26. Grooves 25 are formed on the outer surface of the cavity 2. The grooves 25 correspond to the protrusions 26, so that the clamping effect of the clamping strip 15 on the cavity 2 is better, ensuring the stability of the cavity 2 in the furnace body 1 and improving the working quality.

[0029] A cylinder 27 is installed on the back of the furnace body 1. The output end of the cylinder 27 is provided with a connecting rod 28. 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 penetrate through the furnace body 1. The end of the upper push rod 29 is fixedly connected to the first push rod 12. 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. 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 outwards, the output end of the cylinder 27 will drive the connecting rod 28 to move backward to the rear of the furnace body 1, and the connecting rod 28 will drive the upper push rod 29 and the lower push rod 30 to move backward to the rear of the furnace body 1 at the same time. 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. Through the telescopic movement of the output end of the cylinder 27, the movement of the pushing mechanism 6 and the clamping and positioning mechanism 7 can be driven simultaneously.

[0030] Seals 31 are installed on the surfaces of the upper push rod 29 and the lower push rod 30. After the output end of the cylinder 27 contracts, the seals 31 on the surfaces of the upper push rod 29 and the lower push rod 30 will closely adhere to the surface of the furnace body 1, ensuring the sealing performance 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.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention.
