Description

Technical Field

[0001] This utility model relates to the field of snap-action thermostat technology, specifically a snap-action thermostat. Background Technology

[0002] A snap-action thermostat is a temperature control device based on the principle of bimetallic strip deformation under heat. It achieves circuit switching through a momentary mechanical action and is widely used in overheat protection and precise temperature control scenarios for household appliances and industrial equipment. When the temperature of the main component of the product increases or decreases, the heat generated is transferred to the bimetallic disc. When the set operating temperature is reached, the thermostat quickly activates, causing the contacts to open or close through the mechanism, thereby connecting or disconnecting the circuit and controlling the circuit. When used as overheat protection for motors, snap-action thermostats are connected in series with the motor. They can effectively prevent the burning out of the motor's heating elements and the resulting fire accidents, and have a very wide range of applications.

[0003] In practical use, the aforementioned snap-action thermostat requires screws or other fasteners to connect and install the thermostat's housing to the equipment. However, the metal contact surface on the top of the housing of various thermostats is easily deformed by pressure, which can prevent the normal transfer of temperature. Furthermore, excessive external pressure can also cause the internal metal sheet to deform, resulting in accidental contact of the switch and affecting the normal use of the thermostat. Therefore, we propose a snap-action thermostat. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this invention is to provide a snap-action temperature controller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snap-action thermostat, comprising a main frame, with auxiliary supports fixed to both sides of the bottom end of the main frame, the main frame including a bottom shell frame, pin frames fixed to both sides of the bottom end of the bottom shell frame, a mounting bracket fixed to the top surface of the bottom shell frame, mounting holes provided at both ends of the mounting bracket, a top shell frame fixed to the top surface of the mounting bracket, a snap-fit ​​groove provided to the top surface of the top shell frame, a switch contact fixed to the center of the top surface of the snap-fit ​​groove, an inner metal sheet attached to the top surface of the switch contact, an outer metal cover snapped around the top surface of the snap-fit ​​groove, a void layer provided inside the top surface of the outer metal cover, and support rods arranged inside the void layer.

[0007] Furthermore, the bottom shell frame is fixedly connected to the top shell frame via a mounting bracket, and the mounting holes are symmetrically distributed along both ends of the mounting bracket.

[0008] Furthermore, the top shell frame is fastened to the outer metal cover via a snap-fit ​​groove, and the outer metal cover and the inner metal sheet are aligned vertically.

[0009] Furthermore, the center of the inner metal sheet is aligned with the center of the switch contact, and the inner metal sheet and the outer metal cover are two metal composite layers with different coefficients of thermal expansion.

[0010] Furthermore, the void layer is evenly opened along the inside of the top of the outer metal cover, and the support rods are evenly arranged along the inside of the void layer.

[0011] Furthermore, the auxiliary support includes a support pile, the top of which is fixed along both sides of the bottom surface of the base frame, and the bottom end of the support pile is threadedly connected to a threaded shaft. The bottom end of the threaded shaft is fixed with a support seat, and the bottom surface of the support seat is fitted with a rubber pad.

[0012] Furthermore, the support base forms a threaded structure with the support pile body through a threaded shaft, and the rubber pad is evenly attached to the bottom surface of the support base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This snap-action thermostat consists of a mounting bracket, a top shell bracket, and an outer metal cover. A buffer zone is formed by a gap layer inside the metal cover. When subjected to external stress, it can work with the gap layer to form an external buffer. Therefore, while the internal metal sheet structure is deformed under external pressure, it will not be affected. Furthermore, there are equidistant support rods arranged in a ring around the perimeter of the gap layer, which can maintain the structural support of the outer metal cover under compression, play a protective role, and keep the thermostat structure stable in use.

[0015] This snap-action thermostat can be connected to a wired connection via pin brackets on both sides of the bottom. During wiring, the support stake can be adjusted according to the distance between the bottom housing and the installation environment. By rotating the threaded shaft, the distance between the support base and the support stake can be lengthened or shortened to achieve the adjustment purpose. In conjunction with the rubber pad, friction and insulation are maintained, ensuring the stability of the bottom housing and the installation environment after wiring, thereby further improving the stability during use.

Detailed Implementation

[0021] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0022] It should also be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0023] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0024] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This utility model provides, for example Figure 1-4The shown snap-action thermostat includes a main frame 1, with auxiliary brackets 2 fixed on both sides of the bottom end of the main frame 1. The main frame 1 includes a bottom shell frame 101, with pin brackets 102 fixed on both sides of the bottom end of the bottom shell frame 101. A mounting bracket 103 is fixed on the top surface of the bottom shell frame 101. Mounting holes 104 are provided at both ends of the mounting bracket 103. A top shell frame 105 is fixed on the top surface of the mounting bracket 103. A snap-fit ​​groove 106 is provided on the top surface of the top surface of the snap-fit ​​groove 106. A switch contact 107 is fixed at the center of the top surface of the snap-fit ​​groove 106. An inner metal sheet 108 is attached to the top surface of the switch contact 107. An outer metal cover 109 is snapped around the top surface of the snap-fit ​​groove 106. A gap layer 110 is provided inside the top surface of the outer metal cover 109. A support rod 111 is arranged inside the gap layer 110.

[0027] To prevent the internal metal plate 108 from deforming due to external pressure and causing accidental activation during use, such as... Figure 1-3 As shown, this snap-action thermostat consists of a mounting bracket 103, a top shell bracket 105, and an outer metal cover 109. A buffer area can be formed by the gap layer 110 inside the metal cover 109. When subjected to external stress, it can work with the gap layer 110 to form an external buffer. Therefore, while deformed under external pressure, it will not affect the internal structure of the inner metal sheet 108. Furthermore, there are equidistant support rods 111 arranged in a ring around the perimeter of the gap layer 110, which can maintain the structural support of the outer metal cover 109 body under compression, play a protective role, and keep the thermostat structure stable in use.

[0028] like Figure 1-4 As shown, the auxiliary support 2 includes a support pile 201. The top of the support pile 201 is fixed along both sides of the bottom surface of the bottom shell 101. The bottom end of the support pile 201 is threadedly connected to a threaded shaft 202. The bottom end of the threaded shaft 202 is fixed to a support seat 203. The bottom surface of the support seat 203 is attached to a rubber pad 204.

[0029] To ensure stable operation of the overall snap-action thermostat after wiring at the bottom, such as Figure 1-4 As shown, this snap-action thermostat can be connected to a wired connection via pin brackets 102 on both sides of the bottom. During the wiring process, the support stake 201 can be adjusted according to the distance between the bottom shell 101 and the installation environment. By rotating the threaded shaft 202, the distance between the support base 203 and the support stake 201 can be extended or shortened, thereby achieving the adjustment purpose. In conjunction with the rubber pad 204, while maintaining friction and insulation, the bottom shell 101 and the installation environment are kept stable after wiring, thereby further improving the stability during use.

[0030] In summary, when using this snap-action thermostat, the user first attaches the mounting bracket 103 and the outer metal cover 109 on the top surface of the thermostat to the heat source of the installed equipment. The mounting bracket 103 is then secured using threaded fasteners through the mounting holes 104 at both ends. The thermostat's pin holder 102 is then connected to the wiring. Simultaneously, the length of the auxiliary bracket 2 is adjusted to maintain the support base 203 in the installation environment, ensuring the wiring is stable. During use, when the outer metal cover 109 is compressed at the point where it contacts the heat source, the stress is buffered by the internal void layer 110. When the outer metal cover 109 is deformed by compression, its surface deforms, but the internal inner wall remains undeformed due to the void layer 110 structure, thus not affecting the structure of the inner metal sheet 108, maintaining stable operation.

[0031] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
