[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1, as Figure 1 - Figure 4 As shown, the utility model provides a low heat leakage flexible connection low temperature thermostat, including a low temperature thermostat 1, an inner cavity of the low temperature thermostat 1 is provided with a placement frame 6, a bidirectional screw 9 is provided below the inner cavity of the low temperature thermostat 1, both sides of the outer circle of the bidirectional screw 9 are sleeved with screw sleeves 10, the top of the outer surface of the screw sleeve 10 and both sides of the bottom of the placement frame 6 are fixedly connected with a connecting frame 14, the inner cavity of the connecting frame 14 is provided with a fixing block 15, the two corresponding fixing blocks 15 are fixedly connected by a support rod 13, both sides of the placement frame 6 are fixedly connected with a limiting block 12, both sides of the inner cavity of the low temperature thermostat 1 are provided with a limiting groove 11, one side of the placement frame 6 is rotatably connected with a mounting baffle 7 through a hinge, and both sides of the low temperature thermostat 1 are rotatably connected with a sealing plate 2 through a hinge.

[0024] In this embodiment, when in use, a person places the object to be cooled inside the placement frame 6, and starts the motor 5. The motor 5 drives the bidirectional screw rod 9 to rotate, thereby driving the two screw sleeves 10 to approach each other, so that the connecting frames 14 on the upper parts of the two screw sleeves 10 approach each other, pushing the support rod 13 to rotate, and the connecting frame 14 at the other end of the support rod 13 is connected to the placement frame 6. The rotation of the support rod 13 will cause the placement frame 6 to move upward, and the upward displacement of the support rod 13 drives the coolant inside the placement frame 6 to approach the output port of the low-temperature thermostat 1. Through structural design and the use of a flexible connection method, the connection between the coolant inside the placement frame 6 and the output port of the low-temperature thermostat 1 is achieved. This flexible connection method allows the coolant to be closer to the output port of the low-temperature thermostat 1 more accurately, thereby improving the cooling efficiency, and can ensure that the coolant is closely fitted to the output port of the low-temperature thermostat 1, thereby reducing the possibility of heat leakage. This flexible connection method helps to improve the energy efficiency ratio of the low-temperature thermostat 1 and reduce energy consumption.

[0025] Embodiment 2, as Figure 1 - Figure 4 As shown, the inner cavity of the placement frame 6 is provided with two mounting clamps 17 , and one side of the mounting clamps 17 is fixedly connected to the inner wall of the adjacent placement frame 6 through a plurality of springs 16 .

[0026] One end of the bidirectional screw rod 9 is rotatably connected to the inner wall of the adjacent cryostat 1 through a shaft sleeve, and the other end of the bidirectional screw rod 9 passes through the inner wall of the adjacent cryostat 1 through the shaft sleeve and extends to one side of the cryostat 1.

[0027] A motor 5 is fixedly mounted on one side of the low-temperature thermostat 1 , and an output shaft of the motor 5 is drivingly connected to an extended end of a bidirectional lead screw 9 .

[0028] Both sides of the fixing block 15 are rotatably connected to the inner wall of the adjacent connecting frame 14 via a rotating shaft, and the outer surface of the limiting block 12 is slidably connected to the inner cavity of the corresponding limiting groove 11 .

[0029] A guide frame 18 is fixedly connected to one side of the mounting clamp 17 , and a roller 19 is disposed in the inner cavity of the guide frame 18 .

[0030] Both ends of the roller 19 are rotatably connected to the inner wall of the adjacent guide frame 18 through a rotating shaft.

[0031] An armrest 3 is fixedly connected to one side of the sealing plate 2 , a handle 8 is fixedly connected to one side of the mounting baffle 7 , and a fixed base 4 is fixedly connected to each of the four corner positions at the bottom of the low-temperature thermostat 1 .

[0032] In this embodiment, when in use, the operator pulls the handle 8 and opens the mounting baffle 7 by rotating the hinge, so as to place the coolant in the placement frame 6, align the coolant with the opening of the placement frame 6, and allow the coolant to pass through the roller 19 inside the guide frame 18 and enter between the two mounting clamping plates 17. The design of the roller 19 can help the coolant to enter between the mounting clamping plates 17 more smoothly. As the coolant gradually enters, the spring 16 between the mounting clamping plates 17 will be squeezed to generate a certain elastic force. The operator can gently push or adjust the position of the coolant to make it reach a suitable position between the two mounting clamping plates 17. The elastic force of the spring 16 can help fix the position of the coolant and prevent it from sliding or moving. Through the structural design, the coolant can be ensured to maintain a stable position at the output port to prevent it from moving or tilting due to vibration, impact or other external forces. This stability is necessary to ensure good contact between the coolant and the output port of the cryostat 1 and maximize the heat exchange efficiency, avoiding the coolant from accidentally falling off or sliding at the output port. Within a certain range, it can adapt to coolants of different sizes and shapes, which enables the cryostat 1 to handle a wider variety of coolants and improve the versatility and flexibility of the equipment.

[0033] How it works

[0034] When in use, personnel place the object to be cooled inside the placement frame 6, and start the motor 5. The motor 5 drives the bidirectional screw rod 9 to rotate, thereby driving the two screw sleeves 10 to approach each other, so that the connecting frames 14 on the two screw sleeves 10 approach each other, pushing the support rod 13 to rotate, and the connecting frame 14 at the other end of the support rod 13 is connected to the placement frame 6. The rotation of the support rod 13 will cause the placement frame 6 to move upward, and the upward displacement of the support rod 13 drives the coolant inside the placement frame 6 to approach the output port of the low-temperature thermostat 1. Through the structural design and the use of a flexible connection method, the connection between the coolant inside the placement frame 6 and the output port of the low-temperature thermostat 1 is achieved. The flexible connection method allows the coolant to be more accurately close to the output port of the cryostat 1, thereby improving the cooling efficiency and ensuring that the coolant fits tightly with the output port of the cryostat 1, thereby reducing the possibility of heat leakage. This flexible connection method helps to improve the energy efficiency ratio of the cryostat 1 and reduce energy consumption. The coolant that is not clamped and fixed may move or tilt at the output port due to vibration, impact or other external forces, resulting in unstable contact between the coolant and the output port. The coolant cannot effectively absorb or release heat, thereby affecting its cooling effect. The coolant that is not clamped and fixed may accidentally fall off or slide, causing damage to the coolant. This increases the cost, and clamping and fixing coolants of different sizes is also crucial for the low-temperature thermostat 1 to handle different coolants. The personnel pulls the handle 8 and opens the installation baffle 7 by rotating the hinge to place the coolant in the placement frame 6, aligns the coolant with the opening of the placement frame 6, and allows it to pass through the roller 19 inside the guide frame 18 and enter between the two installation clamps 17. The design of the roller 19 can help the coolant enter between the installation clamps 17 more smoothly. As the coolant gradually enters, the spring 16 between the installation clamps 17 will be squeezed to generate a certain elastic force, and the personnel can gently push or adjust the position of the coolant. , so that it reaches a suitable position between the two mounting clamps 17. The elastic force of the spring 16 can help fix the position of the coolant and prevent it from sliding or moving. Through the structural design, it can ensure that the coolant maintains a stable position at the output port to prevent it from moving or tilting due to vibration, impact or other external forces. This stability is necessary to ensure good contact between the coolant and the output port of the cryostat 1 and maximize the heat exchange efficiency, avoiding the coolant from accidentally falling off or sliding at the output port. Within a certain range, it can adapt to coolants of different sizes and shapes, which enables the cryostat 1 to handle a wider variety of coolants and improves the versatility and flexibility of the equipment.
