It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] Example

[0028] like Figure 1-5 As shown, a high-temperature constant-temperature heating device for a nonlinear optical crystal of a laser comprises a heat preservation chamber 1, a heating block 14 is fixedly connected to the inner bottom end of the heat preservation chamber 1, an insulating door 2 is rotatably connected to one side of the heat preservation chamber 1, a pair of shafts 3 are rotatably connected to the inner wall of the heat preservation chamber 1, a connecting frame 4 is fixedly connected to one end of the pair of shafts 3 close to each other, a connecting strip 5 is arranged on one side of the connecting frame 4 close to each other, a connecting rod 6 is fixedly connected to one side of the connecting strip 5 close to each other, a connecting ring 7 is fixedly connected between the connecting rods 6, four threaded rods 71 ​​are evenly distributed and threadedly connected to the outer circumferential surface of the connecting ring 7, a connecting block 72 is rotatably connected to one end of the four threaded rods 71, and a dense heat insulation cotton 73 is fixedly connected to one side of the connecting block 72;

[0029] A mounting base 11 is fixedly connected to one side of the insulation bin 1, a motor 12 is fixedly connected to one side of the mounting base 11, an output end of the motor 12 is connected to an axis rod 3 on one side, a central control module 8 is fixedly connected to the upper end of the insulation bin 1, and a temperature monitoring probe 9 is fixedly connected to the inner wall of the insulation bin 1.

[0030] When in use, first place the crystal in the middle of the connecting ring 7 with one hand, and use the other hand to rotate the threaded rod 71 on one side, so that the dense heat insulation cotton 73 on one side is close to the crystal, and then change hands to continue the operation. After the threaded rod 71 on the other side is tightened, the four threaded rods 71 ​​cooperate with the dense heat insulation cotton 73 to tightly clamp the crystal, and then close the insulation door 2, turn on the motor 12 and the heating block 14, the heating block 14 can heat the crystal, and the motor 12 can drive the crystal to rotate. Since the edge of the crystal is clamped and limited, and the crystal is located in a suspended position in the middle of the heat preservation chamber 1, the upper and lower sides of the crystal can be heated during the rotation process, thereby further improving the efficiency and uniformity of crystal heating;

[0031] During the heating process, the temperature monitoring probe 9 can monitor the temperature in the heat preservation chamber 1 and cooperate with the central control module 8 to automatically adjust the heating block 14, thereby achieving constant temperature heating of the crystal.

[0032] The heat preservation chamber 1 and the heat preservation door 2 are both made of thickened materials and are filled with heat insulation cotton to improve the heat preservation effect.

[0033] like Figure 1-4As shown, the connecting frame 4 and the connecting strip 5 are slidably connected, a pair of connecting tubes 41 are fixedly connected to one side of the connecting frame 4, a spring 42 is fixedly connected to the inner wall of the connecting tube 41, a connecting seat 43 is fixedly connected to one side of the spring 42, a ball 44 is movably connected to one side of the connecting seat 43, and a pair of notches 51 are provided at one side of the connecting strip 5, and the notches 51 match the outer spherical surface of the ball 44.

[0034] When in use, the connecting ring 7 can slide on the connecting frame 4 through the connecting strip 5. When a person is clamping or disassembling a crystal, the connecting ring 7 can be pulled out from the heat preservation chamber 1 to prevent the narrow space in the heat preservation chamber 1 from affecting the operation of the person, making it convenient for the person to clamp and disassemble the crystal.

[0035] When the connecting strip 5 and the connecting frame 4 are slidably engaged, the ball 44 will be engaged in the slot 51, and under the pressure of the spring 42, the ball 44 can tightly press against the slot 51, thereby limiting the connecting strip 5 to prevent the connecting strip 5 from automatically sliding off during the rotation. A person can apply a certain force to pull the connecting ring 7 out from the outside.

[0036] like Figure 2 and 5 As shown, a cover body 31 is fixedly connected to the outer circumference of the shaft rod 3 on one side. The cover body 31 is filled with cooling oil 32 . A heat pipe 33 is fixedly connected to the outer circumference of the cover body 31 .

[0039] When in use, the sealing effect and the heat preservation effect between the heat insulation door 2 and the heat preservation chamber 1 are improved by the circular heat insulation strip 21 .

[0040] like Figure 1-2 As shown, a magnetic lock 13 is fixedly connected to one side of the heat preservation chamber 1, and a metal block 22 is fixedly connected to one side of the heat insulation door 2. The magnetic lock 13 is adsorbed on the metal block 22, and the magnetic lock 13 is electrically connected to the central control module 8.

[0041] When in use, the magnetic lock 13 contains an electromagnet, which generates magnetic force by turning the power on and off, thereby adsorbing the metal block 22. The turning on and off of the magnetic lock 13 is controlled by the central control module 8, and the insulating door 2 can be opened and closed by pressing the button on the central control module 8.

[0042] In summary, the specific working process of this scheme is: first, place the crystal in the middle of the connecting ring 7 with one hand, and use the other hand to rotate the threaded rod 71 on one side, so that the dense heat insulation cotton 73 on one side is close to the crystal, and then change hands to continue the operation. After the threaded rod 71 on the other side is tightened, the four threaded rods 71 ​​cooperate with the dense heat insulation cotton 73 to tightly clamp the crystal, and then close the insulation door 2, turn on the motor 12 and the heating block 14, the heating block 14 can heat the crystal, and the motor 12 can drive the crystal to rotate. Since the edge of the crystal is clamped and limited, and the crystal is located in a suspended position in the middle of the heat preservation chamber 1, the upper and lower sides of the crystal can be heated during the rotation process, thereby further improving the efficiency and uniformity of crystal heating;

[0043] The connecting ring 7 can slide on the connecting frame 4 through the connecting strip 5. When personnel clamp or disassemble the crystal, the connecting ring 7 can be pulled out from the heat preservation chamber 1 to prevent the narrow space in the heat preservation chamber 1 from affecting the personnel's operation, making it convenient for personnel to clamp and disassemble the crystal.
