Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a temperature controller. Background Art

[0002] A thermostat is a series of automatic control components that physically deform within a switch in response to ambient temperature changes, producing specific effects and switching the device on or off. Alternatively, a temperature protector transmits the temperature to a temperature controller, which then issues a switch command, thereby controlling the device's operation to achieve the desired temperature and energy savings. In existing technology, thermostats are a key component widely used in home appliances, industrial equipment, and other fields. Their performance stability directly impacts the reliability and efficiency of the entire system.

[0003] In traditional thermostat designs, a circuit board is usually used as a transitional connector between the mounting base and the metal adjustment part. Poor contact may occur due to long-term operation or environmental changes, affecting the stable transmission of current, thereby reducing the overall reliability of the thermostat. When connecting traditional thermostats to external wires, the wires often need to be manually fixed and then tightened with screws. This process can easily cause the wires to loosen due to improper operation, affecting the stability of the circuit. Utility Model Content

[0032] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a thermostat of the present invention in conjunction with the accompanying drawings.

[0033] like Figures 1-8 As shown, an embodiment of the present invention provides a thermostat, including a thermostat housing 100 for protecting internal parts, a metal adjustment part 150 for controlling and adjusting the temperature is installed inside the thermostat housing 100, and a sealing back plate 140 for fastening and installing is provided on one side of the thermostat housing 100, and the sealing back plate 140 and the thermostat housing 100 are connected and fastened by screws, the metal adjustment part 150 is installed on the upper end of the sealing back plate 140, and the metal adjustment parts 150 on both sides are connected by a connector 152 installed on the back, and the lower end of the metal adjustment part 150 is connected to the connecting wire through a mounting seat 151.

[0034] The lower end of the thermostat housing 100 is provided with a connecting jack 160 for installing the connecting wire. The side of the thermostat housing 100 is provided with a positioning hole 130 for fixing the wire inserted into the connecting jack 160. The positioning hole 130 and the connecting jack 160 match the notches opened on the side and lower end of the mounting base 151, and are fixed to the mounting base 151 and the internal wire by screws inserted into the positioning hole 130.

[0035] The mounting base 151 and the metal adjustment portion 150 are directly connected, eliminating the need for a PCB transition connection, reducing welding points, making the current more stable, and making product integration more reliable.

[0036] Furthermore, a mounting block 110 for adjusting internal parts is arranged on the surface of the thermostat housing 100, and an adjusting cap 120 for adjusting the detection range of the metal adjusting part 150 is rotatably mounted on the upper end of the mounting block 110. A cross opening is provided at the upper end of the adjusting cap 120 for adjusting the control range of the metal adjusting part 150. An identification portion is arranged on the surface of the mounting block 110 around the adjusting cap 120 to display the numerical value. The cross opening has higher adaptability and can be adapted to a cross or flat-head screwdriver or tool for adjustment.

[0037] Furthermore, a mounting ear 141 for mounting the thermostat housing 100 is installed at the upper end of the outer side of the sealing back plate 140, and a right-angle piece 142 for assisting in fixing the thermostat housing 100 is provided at the lower end of the sealing back plate 140. The thermostat housing 100 can be fixed by guide rails or screws using the mounting ear 141 and the right-angle piece 142, and the fixing method is more flexible.

[0038] A telescopic frame 200 for temporarily fixing the connecting wire is movably installed on one side of the connecting jack 160. The telescopic frame 200 is connected to one side of the inner cavity of the connecting jack 160. The telescopic frame 200 includes a snap-fit ​​frame 210 movably installed at the bottom of the inner cavity of the thermostat housing 100 and a push rod 220 fixedly installed at the lower end of the snap-fit ​​frame 210 for pushing the snap-fit ​​frame 210 to move. A telescopic spring 230 for driving the snap-fit ​​frame 210 to rebound is movably installed on one side of the snap-fit ​​frame 210. One end of the telescopic spring 230 is installed in the inner cavity of the thermostat housing 100.

[0039] When connecting the mounting base 151 to the wires, the wires can be placed one by one into the connecting jack 160. When placing the wires, the push rod 220 installed on one side can be pushed to push the snap-fit ​​frame 210 to move. After the wires are inserted, the telescopic spring 230 pushes the snap-fit ​​frame 210 to rebound, thereby clamping and fixing the wires, making it convenient to tighten with screws without the need for hand-held assistance.

[0040] Furthermore, one end of the locking frame 210 is arranged in an arc shape, which is used to lock and fix the connecting wires. An anti-slip gasket 212 is arranged inside the arc frame to increase friction and fix it. The anti-slip gasket 212 can be arranged in a wavy or U-shaped shape to increase the contact surface and thus increase friction for better fixation.

[0041] A fastening portion 300 for fastening the telescopic frame 200 is provided on one side of the telescopic frame 200. The fastening portion 300 includes a movable frame 310 for fastening the clamping frame 210. The movable frame 310 is movably installed inside a through groove 211 opened on the inner side of the clamping frame 210. The movable frame 310 can be arranged in a U shape, and the clamping frame 210 is installed inside the U-shaped groove. A rotating portion 320 for adjusting the position of the movable frame 310 is installed in the middle of the movable frame 310.

[0042] The rotating part 320 includes a moving tube 321 fixedly installed in the middle of the moving frame 310 and an adjusting screw 322 threadedly installed inside the moving tube 321 for pushing the moving tube 321 to move. The end of the adjusting screw 322 is positioned and installed by a bearing. The end of the adjusting screw 322 is also fixedly installed with a first bevel gear 323 for rotationally adjusting the adjusting screw 322. One side of the first bevel gear 323 is meshed with a second bevel gear 324 for driving the first bevel gear 323 to rotate. One side of the second bevel gear 324 is connected to the rotating member through a connecting rod. A cross notch can be opened on the surface of the rotating member to facilitate the rotation of the rotating member.

[0043] After the wire is installed, the second bevel gear 324 is driven to rotate by the rotating member, which drives the first bevel gear 323 installed on one side to rotate, and then drives the adjusting screw 322 to rotate, and then drives the moving tube 321 installed on one side by a thread to move, and pushes the moving frame 310 to move to one side, fixes the movably installed locking frame 210, clamps the wire, and further fixes it to prevent the wire from loosening and falling.

[0044] Furthermore, rotating wheels 311 for positioning the locking frame 210 are installed on the upper and lower sides of the mobile frame 310. The inner side of the rotating wheel 311 is installed in contact with the outer side of the locking frame 210. The rotating wheel 311 is installed on the upper and lower sides of the mobile frame 310 through the middle axis. The locking frame 210 can be limited by the rotating wheel 311 to avoid misalignment between the locking frame 210 and the mobile frame 310.

[0045] A thermostat working principle: direct connection between the mounting base 151 and the metal adjustment part 150, without the need for a circuit board PCB transition connection, reducing welding points, making the current more stable, and making product integration more reliable.
