[0025] Embodiment 1

[0026] like Figure 1-Figure 4 As shown, the utility model proposes a temperature control device for optical fiber devices, including a temperature control frame 1, a placement plate 6, a fixing plate 7, an adjustment and fixing mechanism and a temperature sensing component. The four corners inside the temperature control frame 1 are provided with guide pillars 8, and a placement plate 6 is slidably arranged between the four guide pillars 8. A fixing plate 7 fixedly connected to the temperature control frame 1 is arranged above the placement plate 6, and the fixing plate 7 is arranged as a hollow structure. A through hole 2 is opened on the top of the temperature control frame 1, and a fan 5 facing the fixing plate 7 is arranged in the through hole 2. A notch 3 is opened at the bottom of the temperature control frame 1, and an adjustment and fixing mechanism is arranged in the notch 3, which is used to drive the placement plate 6 to slide on the guide pillars 8. A temperature sensing component is also arranged on the placement plate 6 for sensing the temperature of the optical fiber device on the placement plate 6.

[0027] like Figure 2 As shown, the adjustment and fixing mechanism includes a bidirectional screw rod 9, a slider 10 and a connecting rod 11. The bidirectional screw rod 9 is rotatably set in the notch 3, and the slider 10 is threadedly connected thereon. The connecting rod 11 is rotatably connected between the slider 10 and the placement plate 6; there are two groups of sliders 10, which are respectively connected to the two sides of the bidirectional screw rod 9 with reverse threads, and one end of the bidirectional screw rod 9 passes through the temperature control frame 1 and is provided with a handle 12.

[0028] The bidirectional screw rod 9 is rotated by the handle 12 , and during the rotation, the slider 10 drives one end of the connecting rod 11 to move linearly, and the other end of the connecting rod 11 supports the placement plate 6 , so that it moves vertically under the limit of the guide column 8 .

[0029] Embodiment 2

[0030] like Figure 1-Figure 4 As shown, the utility model proposes a temperature control device for optical fiber components. Based on the above embodiment, this embodiment also records in detail the specific structural components of the temperature sensing component and the connection method between the temperature sensing component and the temperature control frame 1.

[0031] like Figure 3 and Figure 4 As shown, the temperature sensing component includes a mounting plate 13, a thermistor 14 and a pressing piece. A pressing piece is arranged at the bottom of the mounting plate 13, and a thermistor 14 is arranged on the side. The thermistor 14 is arranged in contact with the optical fiber device to be temperature-controlled, and a pull ring 20 is arranged on the side of the mounting plate 13 away from the thermistor 14, and the mounting plate 13 can be pulled to move by the pull ring 20.

[0032] like Figure 4 As shown, the pressing member includes a limiting column 15, a sliding sleeve 16 and a compression spring 17. A strip groove 18 is opened on the placing plate 6. The limiting column 15 is horizontally arranged in the strip groove 18, and a sliding sleeve 16 is slidably arranged thereon. The sliding sleeve 16 is connected to the mounting plate 13. The compression spring 17 is sleeved on the limiting column 15, and one end of the compression spring 17 is in contact with the sliding sleeve 16.

[0033] like Figure 1 As shown, a controller 19 is provided on one side of the temperature control rack 1, and the thermistor 14 and the fan 5 are both connected to the controller 19. When the temperature of the optical fiber device is too high, the thermistor 14 senses the heat and generates a feedback voltage which is transmitted to the controller 19. The controller 19 processes the feedback voltage and finally feeds it back to the fan 5. The fan 5 dissipates the heat of the optical fiber device to achieve temperature control.

[0034] In summary, when the utility model is in use, the pull ring 20 is pulled by one hand, and the pull ring 20 drives the mounting plate 13 and the thermistor 14 to move, so that the sliding sleeve 16 squeezes the compression spring 17, and the optical fiber device to be temperature-controlled is placed on the placement plate 6 with the other hand, and then the handle 12 is turned, and the handle 12 drives the bidirectional screw rod 9 to rotate. During the rotation process, the bidirectional screw rod 9 drives the slider 10 to move synchronously in the opposite direction, and the slider 10 drives one end of the connecting rod 11 to make linear movement, and the other end of the connecting rod 11 drives the placement plate 6 and the optical fiber device to move upward synchronously until the optical fiber device is clamped between the fixing plate 7 and the placement plate 6. , that is, the installation of the optical fiber device is completed, and then the pull ring 20 is loosened, and the installation plate 13 is reset under the action of the elastic restoring force of the compression spring 17, so that the varistor is in contact with the optical fiber device. During the temperature control process, a reasonable temperature range is set by the controller 19, and the temperature of the optical fiber device is monitored by the thermistor 14. When the temperature is too high, the thermistor 14 senses the heat and generates a feedback voltage which is transmitted to the controller 19. After the feedback voltage is processed by the controller 19, it is finally fed back to the fan 5. The fan 5 will dissipate the heat of the optical fiber device to achieve temperature control.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
