[0002] A temperature control box is a device used to monitor and control temperature. It uses built-in temperature sensors and controllers to achieve precise temperature control, thereby ensuring that related equipment or systems operate within the normal operating temperature range and preventing problems caused by overheating or overcooling.

[0003] In the prior art, there is a temperature control box assembly and a refrigeration device using the same (Publication No.: CN105451489B).

This temperature control box assembly is not only waterproof but also highly reliable.

[0004] However, during actual use, it needs to be connected to an external circuit. At this time, the connector on the temperature control box that is connected to the outside world will be in direct contact with the external environment. Impurities such as dust or water in the external environment will easily enter the temperature control box along the connector, thereby causing damage to the thermostat. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5 As shown, the utility model proposes a main transformer integrated temperature control box with a protective box cover, comprising: a control panel 1, a protective box cover 2, a protective frame 3, a sealing bottom plate 4, an arc blocking plate 6 and a sealing assembly.

[0023] The protective box cover 2 is installed on one side of the control panel 1 by fastening bolts. In actual use, the thermostat needs to be placed in the protective box cover 2, and the thermostat is connected to the control panel 1 to display the temperature control coefficient. A waterproof setting is adopted between the protective box cover 2 and the control panel 1, and the setting can be constructed using existing technology. A wiring groove is provided on the protective box cover 2 for connecting the thermostat connector in the temperature control box with the external circuit. A protective frame 3 is installed on the protective cover 2, and a sealing bottom plate 4 is provided on the protective frame 3. The protective frame 3 and the sealing bottom plate 4 form a relatively closed space outside the wiring groove. A sealing arc plate 6 is installed on the protective frame 3 and the sealing bottom plate 4. The corresponding two sealing arc plates 6 form a cylinder for limiting the circuit. The sealing arc plate 6 is inclined, that is, the cylinder composed of the two corresponding sealing arc plates 6 is also inclined, which can prevent water from flowing into the protective frame 3 along the external circuit.

[0024] The airbag 7 is provided with a sealing assembly on the blocking arc plate 6. The sealing assembly uses an airbag as a sealing element, and the airbag 7 is inflated to complete the sealing between the two blocking arc plates 6 to prevent external impurities from entering the protective frame 3. The sealing assembly is composed of an airbag 7, an air guide main pipe 8, a push rod 9, a piston and a limit bolt 10. The airbag 7 is arranged on the inner wall of the blocking arc plate 6, and the air guide main pipe 8 is arranged on the blocking arc plate 6. A branch pipe is installed on the air guide main pipe 8, and the branch pipe is connected to the airbag 7. The push rod 9 is slidably installed on the air guide main pipe 8, and the piston is arranged in the air guide main pipe 8. The piston is connected to the push rod 9. A plurality of threaded grooves are provided on the push rod 9, and the limit bolt 10 is threadedly installed on the air guide main pipe 8. One end of the limit bolt 10 extends into the corresponding threaded groove and is adapted to the threaded groove. By setting the limit bolt 10 and the threaded groove, the movement of the push rod 9 can be limited to ensure the inflation stability of the airbag 7, and then ensure the protection effect of the temperature control box.

[0025] A wire trough seat 5 is installed on the sealing bottom plate 4, and a plurality of wire clamps are provided on the wire trough seat 5. The wire clamps are made of plastic and are deformable, which is convenient for clamping the lines. The number of wire trough seats 5 can be set to multiple, so that the lines can be clamped and limited as needed, thereby making the lines arranged in an orderly manner in the protective frame 3 to avoid messy placement of the lines.

[0026] A holding block 11 is installed on the sealing bottom plate 4, and a holding groove is provided on the holding block 11. An adjusting block 12 is installed on the protective frame 3, and a receiving groove is provided on the adjusting block 12. A clamping block 13 is provided on the adjusting block 12, and the clamping block 13 is slidably connected to the inner wall of the receiving groove. One side of the clamping block 13 extends into the clamping groove and adapts to the clamping groove. A return spring 14 is provided in the receiving groove, and the return spring 14 is connected to the clamping block 13. A push button 15 is slidably installed on the adjusting block 12, and the push button 15 is connected to the clamping block 13. The clamping block 13 is set to be inclined toward the side of the holding block 11, so that the holding block 11 can push the clamping block 13 to move toward the receiving groove.

[0027] In this embodiment, the thermostat is placed in the protective box cover 2, and the connector connecting the thermostat to the outside world is connected to the external circuit through the cable groove. The wire clamp on the wire groove seat 5 can clamp and limit the wire to ensure that the wire is placed neatly. After the wire is arranged, the sealing bottom plate 4 can be pushed to the bottom of the protective frame 3 to complete the sealing operation on the outside of the cable groove, thereby preventing foreign matter such as dust or water from entering the temperature control box through the connector.

[0028] During the process of pushing the sealing bottom plate 4 upward, the clamping block 13 is pushed by the clamping block 11 into the receiving groove. After the sealing bottom plate 4 is completely in contact with the bottom of the protective frame 3, the clamping block 13 enters the clamping groove of the clamping block 11 under the action of the return spring 14, thereby completing the connection between the sealing bottom plate 4 and the protective frame 3. Similarly, when disassembling, it is only necessary to pull the push button 15 to drive the clamping block 13 out of the clamping groove, so that the sealing bottom plate 4 can be separated from the protective frame 3. This can improve the maintenance efficiency of the temperature control box and the connection with the external circuit;

[0029] After the sealing bottom plate 4 is connected to the protective frame 3, first rotate the limit bolt 10 to disengage the corresponding threaded groove, and then push the push rod 9 to drive the piston to move, pushing the airflow in the air guide main pipe 8 into the airbag 7, so that the airbag 7 expands, so that the space between the corresponding two sealing arc plates 6 can be blocked, or the airbag 7 can be made to contact the surface of the external line more closely. In summary, the sealing effect in the protective frame 3 can be further guaranteed, thereby improving the safety of the temperature control box.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
