Description

Technical Field

[0001] The present invention relates to the technical field of synthetic diamonds, and more specifically, to a furnace body structure of a synthetic diamond crystal growth device. Background Art

[0002] Synthetic diamonds are polycrystalline diamonds formed by the polymerization of diamond crystals with a diameter of 10 to 30 nanometers. The molecular structure of synthetic diamonds is not the complete octahedral structure of natural diamonds but a complex structure, which will cause phosphorescence. There are two methods for the production of synthetic diamonds: the high-temperature and high-pressure synthesis method and the chemical vapor deposition synthesis method. The high-temperature and high-pressure synthesis method means that temperature and pressure are still two key factors in crystal manufacturing. Professional diamond jewelry experts introduced that the method is to manufacture diamonds in a ceramic container rather than underground. Water pressure provides high pressure, and electricity generates high temperature, causing carbon to form crystals around a seed crystal with a diameter of 1 mm made of natural diamonds. The chemical vapor deposition synthesis method means that after natural gas and nitrogen are heated, a carbon plasma is formed in a pressure chamber the size of a dishwasher. The plasma is continuously deposited on the carbon bottom layer at the bottom of the pressure chamber and gradually accumulates and hardens to form diamond wafers, which are then cut into gemstone shapes. Currently, the chemical vapor deposition synthesis method is generally used to produce synthetic diamonds.

[0003] Due to the dependence on a multi-layer sealing design, the furnace body structure of traditional diamond crystal growth devices requires cumbersome sealing steps during each opening and closing, such as repeatedly calibrating the position of the sealing ring or adjusting the pressure balance. Operators need to manually adjust components multiple times, resulting in a long start-up and shutdown time for the device. This complex operation process not only significantly extends the crystal growth cycle but also increases the frequency of manual intervention, affecting the overall production efficiency. In addition, frequent sealing maintenance and precision requirements further exacerbate the inconvenience of use, making the operation time-consuming and laborious. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a furnace body structure of a synthetic diamond crystal growth device, which can realize automatic opening and closing of the furnace body.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] The furnace body structure of a synthetic diamond crystal growth device includes a chassis. A top cover is provided on the upper side of the chassis. Support columns are fixedly installed between the top cover and the chassis. An upper cover is arranged between the top cover and the chassis.

An airbag one is fixedly installed between the slider and the inner wall of the first chute.

[0008] A limiting cavity is opened inside the pressing rod. A shape memory alloy is slidably connected inside the limiting cavity. An anti-slip pad is arranged at one end of the shape memory alloy. A first connecting pipe is communicated between the limiting cavity and the airbag one.

[0009] The buckle mechanism includes a reinforcing member arranged outside the fixing component. The reinforcing member includes a support member arranged on the upper side of the first chute. The support member is fixedly connected with the chassis. A transmission rod is rotatably connected to the upper end of the support member.

[0010] Support shafts are fixedly installed on both sides of the first wedge block. A second chute is opened on the front end surface of the transmission rod. The support shafts are slidably connected with the second chute. A clamping plate is fixedly installed at the other end of the transmission rod.

[0011] Both the fixing component and the reinforcing member are provided with three groups and are arranged in a ring and dispersed.

[0012] The buckle mechanism further includes a sealing member arranged inside the chassis. The sealing member includes a groove opened on the lower end surface of the upper cover. A slot corresponding to the upper cover is opened on the upper end surface of the chassis. A convex ring is fixedly installed in the slot corresponding to the groove.

[0013] A slide rail is fixedly installed between the top cover and the chassis. An extrusion plate is slidably connected inside the slide rail. One end of the extrusion plate is fixedly connected with the upper cover. An airbag two is fixedly installed between the extrusion plate and the lower end surface inside the slide rail.

[0014] Both inner walls on two sides of the slot are fixedly installed with third air bags. A transition cavity is communicated and arranged between the two groups of third air bags. A second communication pipe is communicated and arranged between the transition cavity and the second air bag.

On the premise of maintaining high sealing performance, the opening and closing operation steps of the improved structure are reduced to a single trigger action, reducing the complexity of manual operation and simultaneously improving the operation efficiency and running stability of the equipment.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 5 , a furnace body structure of an artificial diamond crystal growth device, including a chassis 1, a top cover 2 is arranged on the upper side of the chassis 1, support columns 3 are fixedly installed between the top cover 2 and the chassis 1, an upper cover 4 is arranged between the top cover 2 and the chassis 1, a support sliding rod 5 is fixedly installed on the outer surface of the upper cover 4, the support sliding rod 5 is slidably connected with the support column 3, a motor 6 is fixedly installed on the upper end surface of the chassis 1, a threaded rod 7 is fixedly installed at the end of the output shaft of the motor 6, the upper end of the threaded rod 7 is rotatably connected with the top cover 2, a threaded sliding rod 8 is fixedly installed on the outer surface of the upper cover 4, one end of the threaded sliding rod 8 is in screw drive connection with the threaded rod 7, a buckle mechanism is arranged on the upper side of the chassis 1, the buckle mechanism includes a fixing component arranged on the upper side of the upper cover 4, the fixing component includes a cross bar 9 fixedly installed on the outer surface of the upper cover 4, a first wedge block 10 is fixedly installed at the end of the cross bar 9, a first chute 11 is opened on the upper end surface of the chassis 1, a slider 12 is slidably connected inside the first chute 11, a spring 13 is fixedly installed between the slider 12 and the inner wall of the first chute 11, a second wedge block 14 is fixedly installed on the upper end surface of the slider 12 corresponding to the first wedge block 10, and a pressing rod 15 is fixedly installed at one end of the second wedge block 14.

[0027] When the top cover 2 needs to be closed, by starting the motor 6, the threaded rod 7 rotates. The threaded rod 7 is in screw drive connection with the threaded sliding rod 8 fixedly installed on the outer surface of the upper cover 4. Therefore, the threaded sliding rod 8 will carry the upper cover 4 down, and the lower edge of the upper cover 4 is embedded into the slot 31, so that the convex ring 30 is inserted into the groove 29. While the upper cover 4 is descending, the first wedge block 10 will be carried down by the cross bar 9. When the first wedge block 10 descends, it will collide and slide with the second wedge block 14 on the slider 12, and drive the slider 12 to slide inward inside the first chute 11, and drive the pressing rod 15 to displace inward to abut against the upper cover 4. The three pressing rods 15 synchronously abut against the upper cover 4 for fixation.

[0028] The fixing component includes a reinforcing member arranged inside the pressing rod 15. The reinforcing member includes a pressing ring 16 fixedly installed on the lower side of the outer surface of the upper cover 4, and an air bag 17 is fixedly installed between the slider 12 and the inner wall of the first chute 11.

[0029] A limiting cavity 18 is provided inside the compression bar 15. A shape memory alloy 20 is slidably connected inside the limiting cavity 18. An anti-slip pad is provided at one end of the shape memory alloy 20. A first communication pipe 19 is provided for communication between the limiting cavity 18 and the first airbag 17.

[0030] Secondly, when the slider 12 displaces inside the first chute 11, it will squeeze the first airbag 17, causing the gas inside the first airbag 17 to enter the inside of the limiting cavity 18 through the first communication pipe 19, and causing the shape memory alloy 20 inside the limiting cavity 18 to extend, so that the lower end of the shape memory alloy 20 presses down against the pressing ring 16, providing a vertical downward pressure, thereby improving the fixing effect on the upper cover 4.

[0031] The buckle mechanism includes a reinforcement member provided outside the fixing component. The reinforcement member includes a support member 21 provided on the upper side of the first chute 11. The support member 21 is fixedly connected to the chassis 1. The upper end of the support member 21 is rotatably connected to a transmission rod 23.

[0032] Support shafts 22 are fixedly installed on both sides of the first wedge block 10. A second chute 24 is provided on the front end face of the transmission rod 23. The support shafts 22 are slidably connected to the second chute 24. A clamping plate 25 is fixedly installed at the other end of the transmission rod 23.

[0033] Both the fixing component and the reinforcement member are provided with three groups and are arranged in a ring in a dispersed manner.

[0034] The support shafts 22 on the first wedge block 10 synchronously descend with the upper cover 4. The support shafts 22 are slidably connected to the second chute 24 on the transmission rod 23. When the support shafts 22 slide down, the transmission rod 23 will deflect upward around the support member 21 towards the upper cover 4, so that the clamping plate 25 at the upper end of the transmission rod 23 is in close contact with the upper cover 4. Similarly, the three groups of clamping plates 25 are synchronously in close contact with the upper cover 4, improving the fixing effect on the upper cover 4.

[0035] The buckle mechanism further includes a sealing member provided inside the chassis 1. The sealing member includes a groove 29 provided on the lower end face of the upper cover 4. A slot 31 corresponding to the upper cover 4 is provided on the upper end face of the chassis 1. A convex ring 30 is fixedly installed in the slot 31 corresponding to the groove 29.

[0036] A slide rail 26 is fixedly installed between the top cover 2 and the chassis 1. A pressing plate 27 is slidably connected inside the slide rail 26. One end of the pressing plate 27 is fixedly connected to the upper cover 4. An airbag two 28 is fixedly installed between the pressing plate 27 and the lower end face inside the slide rail 26.

[0037] Airbag threes 33 are fixedly installed on both inner walls of the two sides of the slot 31. A transition cavity 32 is provided for communication between the two airbag threes 33. A second communication pipe 34 is provided for communication between the transition cavity 32 and the airbag two 28.

[0038] The upper cover 4 descends, causing the extrusion plate 27 to descend. The extrusion plate 27 will then descend inside the slide rail 26 and squeeze the second airbag 28, causing the gas inside the second airbag 28 to enter the two groups of third airbags 33 respectively through the second connecting pipe 34 and the transition cavity 32. The two groups of third airbags 33 expand to fill the gap between the upper cover 4 and the chassis 1, improving the airtightness of the device.

[0039] Sealing rubber strips are fixedly installed inside both the convex ring 30 and the groove 29, and an anti-slip pad is fixedly installed on the inner wall of the clamping plate 25.

[0040] Due to relying on a multi-layer sealing design, the furnace body structure of traditional diamond crystal growth equipment requires cumbersome sealing steps during each opening and closing, such as repeatedly calibrating the position of the sealing ring or adjusting the pressure balance. Operators need to manually adjust components multiple times, resulting in a long start-up and shutdown time for the equipment. This complex operation process not only significantly prolongs the crystal growth cycle but also increases the frequency of manual intervention, affecting the overall production efficiency. In addition, frequent sealing maintenance and precision requirements further exacerbate the inconvenience of use, making the operation time-consuming and laborious. Therefore, in this solution, a buckle mechanism is set up to automatically open the furnace body, and the fixing effect and stability of the furnace body are strengthened under the action of the fixing component and the reinforcement. At the same time, elastic sealing components are added at the key joint surfaces, and the gaps are filled through pressure-adaptive deformation, reducing the repeated calibration steps required for traditional multi-layer sealing. On the premise of maintaining high airtightness, the opening and closing operation steps of the improved structure are reduced to a single trigger action, reducing the complexity of manual operation and simultaneously improving the operation efficiency and running stability of the equipment.

[0041] Usage method: When the top cover 2 needs to be closed, by starting the motor 6, the threaded rod 7 rotates. The threaded rod 7 is in spiral transmission connection with the threaded slide rod 8 fixedly installed on the outer surface of the upper cover 4. Therefore, the threaded slide rod 8 will carry the upper cover 4 downwards and embed the lower edge of the upper cover 4 into the slot 31, causing the convex ring 30 to insert into the groove 29. When the upper cover 4 descends, it will carry the wedge block 10 downwards through the cross bar 9. When the wedge block 10 descends, it will collide and slide with the wedge block 14 on the slider 12 and drive the slider 12 to slide inwards inside the first chute 11, and drive the pressure rod 15 to displace inwards and abut against the upper cover 4. The three pressure rods 15 simultaneously abut against the upper cover 4 for fixation;

[0042] Secondly, when the slider 12 displaces inside the first chute 11, it will squeeze the first airbag 17, causing the gas inside the first airbag 17 to enter the inside of the limiting cavity 18 through the first connecting pipe 19, and causing the shape memory alloy 20 inside the limiting cavity 18 to extend, and the lower end of the shape memory alloy 20 presses downwards against the pressure ring 16 to provide a vertical downward pressure, thereby improving the fixing effect on the upper cover 4;

[0043] The support shaft 22 on the first wedge block 10 synchronously follows the upper cover 4 to descend. The support shaft 22 is slidably connected to the second chute 24 on the transmission rod 23. When the support shaft 22 slides downward, it will cause the transmission rod 23 to deflect upward around the support member 21 towards the upper cover 4. Furthermore, the clamping plate 25 at the upper end of the transmission rod 23 will be in close contact with the upper cover 4. Similarly, the three groups of clamping plates 25 are synchronously in close contact with the upper cover 4, improving the fixing effect on the upper cover 4;

[0044] The descent of the upper cover 4 drives the extrusion plate 27 to descend. The extrusion plate 27 will then descend inside the slide rail 26 and squeeze the second airbag 28, causing the gas inside the second airbag 28 to enter the two groups of third airbags 33 respectively through the second connecting pipe 34 and the transition cavity 32. The two groups of third airbags 33 expand to fill the gap between the upper cover 4 and the chassis 1, improving the airtightness of the device.

[0045] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
