Technical Field
[0001] This utility model relates to the field of temperature controllers, and in particular to a temperature controller that is easy to assemble. Background Technology
[0002] Existing temperature controllers typically consist of two parts: a switching assembly and a power component. When the temperature is too high, the power component acts on the switching assembly, causing the switching assembly to disconnect and thus breaking the circuit.
[0003] The existing temperature controllers are extremely cumbersome to assemble during the production process, which affects production efficiency. At the same time, the complex connection between the switching components and the power components leads to inaccurate operation of the power components, which affects the disconnection protection function of the switching components. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a thermostat that is easy to assemble, including a switching mechanism. The switching mechanism includes a first terminal, a spring assembly, a stationary contact, a second terminal, and a support plate arranged sequentially from top to bottom. The spring assembly contacts the first terminal, and the stationary contact contacts the second terminal. It also includes a power component. The end of the support plate is provided with a locking slot. The power component is provided with a fixing rod, which engages with the locking slot, fixing the power component below the spring assembly. The power component is used to push the spring assembly upwards.
[0005] According to some embodiments of the present invention, the switching mechanism further includes a pressure plate, which is located above the reed assembly. An adjusting shaft is threaded onto the pressure plate, and a pressure rod is installed inside the adjusting shaft. The bottom end of the pressure rod contacts the reed assembly.
[0006] According to some embodiments of this utility model, a limit rod is vertically provided at the end of the pressure plate, a limit piece is fitted on the adjusting shaft, and a push piece is provided on the outer edge of the limit piece. The push piece contacts the limit rod, causing the adjusting shaft to stop rotating.
[0007] According to some embodiments of the present invention, the switching mechanism further includes rivets, which are sequentially fitted from top to bottom onto the pressure plate, the first terminal, the spring assembly, the stationary contact piece, the second terminal, and the support plate.
[0008] According to some embodiments of this utility model, the rivet is further fitted with three ceramic rings, which are respectively disposed between the pressure plate and the first terminal, between the spring assembly and the stationary contact piece, and between the second terminal and the support plate.
[0009] According to some embodiments of this utility model, a ceramic tube is also fitted onto the rivet.

The other end of the second reed is provided with a moving contact, and the stationary contact is provided with a stationary contact, which is used to contact the moving contact.
[0011] According to some embodiments of the present invention, the power component is equipped with a push rod, which is used to push the connecting end upward.
[0012] During production and assembly, the switching mechanism is assembled first. After assembly, the fixing rod of the power component is inserted into the support plate, fixing the power component below the spring assembly, which improves assembly efficiency and production efficiency. At the same time, it ensures that the power component is accurately installed below the switching assembly, so that the power component can accurately disconnect the switching assembly, enabling the temperature controller to effectively carry out protection work.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0016] In the description of this utility model, "more than" means two or more, and "greater than," "less than," "exceeding," etc., are understood to exclude the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.
[0017] Reference Figure 1 A conveniently assembled temperature controller includes a switching mechanism. The switching mechanism includes a first terminal 100, a reed assembly 200, a stationary contact 300, a second terminal 400, and a support plate 500 arranged sequentially from top to bottom. The reed assembly 200 contacts the first terminal 100, and the stationary contact 300 contacts the second terminal 400. The reed assembly 200 is used to contact the stationary contact 300. The controller also includes a power component 600. The end of the support plate 500 is provided with a bayonet 510. The power component 600 is provided with a fixing rod 610, which is inserted into the bayonet 510 to fix the power component 600 below the reed assembly 200. The power component 600 is used to push the reed assembly 200 upward.
[0018] During production and assembly, the switch mechanism is assembled first. After assembly, the fixing rod 610 of the power component 600 is inserted into the slot 510, fixing the power component 600 below the spring assembly 200, thus improving assembly efficiency and production efficiency. At the same time, it ensures that the power component 600 is accurately installed below the switch assembly, enabling the power component 600 to accurately disconnect the switch assembly, allowing the temperature controller to effectively perform its protective function.
[0019] In this embodiment, the power component 600 includes a diaphragm, a capillary tube, and a temperature sensing cylinder. The temperature sensing cylinder is in contact with the object being measured. As the temperature of the object being measured rises, the liquid inside the temperature sensing cylinder will expand to a certain extent. The liquid then enters the diaphragm through the capillary tube, thereby causing the deformation surface of the diaphragm to deform.
[0020] When the temperature of the object being measured decreases, the liquid inside the sensing cylinder stops expanding, stops entering the diaphragm, and returns to the sensing cylinder through the capillary tube.
[0021] Reference Figure 2 , 4 As shown, the switching mechanism also includes a pressure plate 700, which is located above the reed assembly 200. An adjusting shaft 800 is threaded onto the pressure plate 700, and a pressure rod 810 is installed inside the adjusting shaft 800. The bottom end of the pressure rod 810 contacts the reed assembly 200. By rotating the pressure rod 810, the height of the pressure rod 810 is changed.
[0022] Reference Figure 4As shown, the reed assembly 200 includes a first reed 210 and a second reed 220. One end of the first reed 210 contacts the first terminal 100, and the other end of the first reed 210 is connected to one end of the second reed 220 to form a connecting end 230. The connecting end 230 is located above the power member 600. The first reed 210 is provided with a first spring tongue 211, which contacts the bottom end of the pressure rod 810. The other end of the second reed 220 is provided with a moving contact 221, and the stationary contact 300 is provided with a stationary contact 310. The stationary contact 310 is used to contact the moving contact 221. The second reed 220 is provided with a second reed tongue 222, which is connected to the first reed tongue 211.
[0023] Under normal operating conditions, the first terminal 100 and the second terminal 400 connect the circuit and conduct normally. The stationary contact 310 and the moving contact 221 are in contact, thus connecting the circuit. However, when the temperature is too high, the power component 600 senses the temperature change and provides power to push the connecting end 230. Due to the power of the power component 600, the second spring 220 is deformed. At this time, the moving contact is disconnected from the stationary contact 310, and the circuit is broken, which serves to protect the circuit.
[0024] Reference Figure 3 As shown, a push rod 620 is mounted on the power component 600, which is used to push the connecting end 230 upward.
[0025] Reference Figure 3 As shown, a limit rod 710 is vertically provided at the end of the pressure plate 700, and a limit piece 820 is fitted on the adjusting shaft 800. A push piece 830 is provided on the outer edge of the limit piece 820. When the adjusting shaft 800 is rotated, the limit piece 820 can abut against the limit rod 710. At this time, the adjusting shaft 800 cannot be rotated, which effectively prevents the temperature controller from failing and provides better protection.
[0026] Reference Figure 2 As shown, during assembly, the pressure plate 700, the first terminal 100, the spring assembly 200, the stationary contact piece 300, the second terminal 400, and the support plate 500 are sequentially installed from top to bottom on the rivet 900.
[0027] To ensure insulation, three ceramic rings 910 are also fitted on the rivet 900. The first ceramic ring 910 is located between the pressure plate 700 and the first terminal 100, the second ceramic ring 910 is located between the spring assembly 200 and the stationary contact 300, and the third ceramic ring 910 is located between the second terminal 400 and the support plate 500.
[0028] To further improve insulation, a ceramic tube 920 is also fitted onto the rivet 900.
