[0007] A first clamping arm;

[0008] A second clamping arm, which is arranged opposite to the first clamping arm along a first direction to form a clamping space for clamping the thermostat; and

[0015] In one embodiment, the elastic connecting portion has a second limiting portion protruding along the first direction, and the second limiting portion can abut against the main body along the axial direction of the fixing hole to prevent the elastic connecting portion from disengaging from the fixing hole.

[0016] In one embodiment, when the first clamping arm and / or the second clamping arm has a first limiting portion, the elastic connecting portion further includes a transition portion connected between the first limiting portion and the second limiting portion, and the transition portion can have a radial gap with the fixing hole when the elastic connecting portion is elastically clamped with the fixing hole.

[0017] In one embodiment, the second limiting portion includes at least two, and the at least two second limiting portions respectively protrude from both sides of the elastic connecting portion along the first direction.

[0018] In one embodiment, the second limiting portion is formed by bending at least part of the elastic connecting portion outward along the first direction.

[0025] For the above-mentioned thermostat fixing structure and temperature regulation device, when it is necessary to install the thermostat on the body, the operator can apply force to the first clamping arm and the second clamping arm in the direction of approaching each other, causing the elastic connecting part to deform. At this time, the elastic connecting part can be inserted into the fixing hole. After that, the operator no longer applies force to the first clamping arm and the second clamping arm. At this time, under the action of the elastic restoring force, the elastic connecting part can be clamped in the fixing hole of the body, so as to clamp the thermostat located in the clamping space and keep it in the clamping space, so that the thermostat is firmly fixed on the body through the thermostat fixing structure.

[0041] Figure 1 The structural schematic diagram of the thermostat fixing structure in an embodiment of the present application is shown, Figure 2 The partial structural schematic diagram of the temperature adjustment device in an embodiment of the present application is shown. For ease of description, the drawings only show the structures related to the embodiments of the present invention.

[0042] Referring to the drawings, an embodiment of the present application provides a thermostat fixing structure 100, which includes a first clamping arm 10, a second clamping arm 20 and an elastic connecting portion 30. The thermostat fixing structure 100 of the present application is used to fix the thermostat 200 to the body 300. A fixing hole 310 ( Figure 3 shown) is provided on the body 300, and the thermostat fixing structure 100 can cooperate with the fixing hole 310 to fix the thermostat 200 to the body 300. Specifically, the body 300 can be the body of an oven or the body 300 of other applicable thermostat fixing structures, which is not limited herein.

[0043] The second clamping arm 20 is arranged opposite to the first clamping arm 10 along the first direction to form a clamping space 40 for clamping the thermostat 200. Both ends of the elastic connecting portion 30 are respectively connected to one end of the first clamping arm 10 and one end of the second clamping arm 20. Among them, the elastic connecting portion 30 can deform along the first direction under an external force to elastically snap into the fixing hole, so as to provide a force for keeping the thermostat 200 clamped in the clamping space 40.

[0044] Thus, as Figure 3 shown, when the thermostat 200 needs to be installed on the body 300, the operator can apply force to the first clamping arm 10 and the second clamping arm 20 in the direction of approaching each other, prompting the elastic connecting portion 30 to deform. At this time, the elastic connecting portion 30 can extend into the fixing hole 310. After that, the operator no longer applies force to the first clamping arm 10 and the second clamping arm 20. As Figure 4 shown, at this time, under the action of the elastic restoring force, as Figure 6 shown, the elastic connecting portion 30 can be clamped to the fixing hole 310 of the body 300, so as to clamp the thermostat 200 located in the clamping space 40 and keep it in the clamping space 40, so that the thermostat 200 is firmly fixed on the body 300 through the thermostat fixing structure 100.

[0045] The thermostat fixing structure 100 of the present application is convenient to operate and does not require additional tools to fix the thermostat 200 on the body 300. Therefore, the fixing efficiency is improved.

[0046] Please refer to Figure 1 again. Specifically, in the embodiment of the present application, the first clamping arm 10, the second clamping arm 20 and the elastic connecting portion 30 are integrally formed. Specifically, the first clamping arm 10, the second clamping arm 20 and the elastic connecting portion 30 are formed by bending a spring piece. In some embodiments, the material of the thermostat fixing structure 100 is stainless steel, that is, the material of the spring piece is stainless steel.

[0047] It should be noted that the spring piece has a certain width, which can provide sufficient elastic deformation force for the elastic connecting portion 30, and can make the clamping areas of the first clamping arm 10 and the second clamping arm 20 in contact with the thermostat 200 larger, improving the clamping stability.

[0048] In order to enable the operator to operate in place and not affect the clamping ability of the first clamping arm 10 and the second clamping arm 20 when operating to extend the elastic connecting portion 30 into the fixing hole 310 and elastically clamp it, in some embodiments, the first clamping arm 10 is provided with a first limiting portion 11, and the first limiting portion 11 can abut against the body 300 along the axial direction of the fixing hole 310 to limit the movement of the first clamping arm 10. In another embodiment, the second clamping arm 20 may also have a first limiting portion 11. In other embodiments, both the first clamping arm 10 and the second clamping arm 20 may have a first limiting portion 11, which is not limited here.

[0049] Further, the first limiting portion 11 protrudes from the elastic connecting portion 30 along a second direction perpendicular to the first direction. Protruding from the elastic connecting portion 30 along the second direction can avoid being affected by the change in the relative position relationship between the first clamping arm 10 and the second clamping arm 20, and changing the abutting relationship of its main body 300. Therefore, the first limiting portion 11 can always maintain abutment with the main body 300 after the elastic connecting portion 30 extends into the fixing hole 310, reducing the operation difficulty and improving the operation stability.

[0050] Furthermore, there are at least two first limiting portions 11, and two of the first limiting portions 11 are respectively located on both sides of the first clamping arm 10 or the second clamping arm 20 along the second direction. In this way, the abutting and limiting relationship between the first limiting portion 11 and the main body 300 can be made more reliable.

[0051] Specifically in the embodiment of the present application, the width of the first clamping arm 10 is greater than the width of the elastic connecting portion 30. In this way, the first limiting portion 11 can be formed on one side of the first clamping arm 10 close to the elastic connecting portion 30. Similarly, the first limiting portion 11 of the second clamping arm 20 can also be formed in this way, which can simplify the structures of the first clamping arm 10 and the second clamping arm 20.

[0052] As Figure 5 shown, in some embodiments, when the elastic connecting portion 30 is elastically clamped with the fixing hole 310, at least part of it extends into one side of the fixing hole 310, and the first clamping arm 10 and the second clamping arm 20 are located on the other side of the fixing hole 310. In this way, the elastic connecting portion 30 can be more stably elastically clamped in the fixing hole 310, ensuring reliable fixation of the thermostat 200.

[0053] Further, the elastic connecting portion 30 has a second limiting portion 31 protruding along the first direction, and the second limiting portion 31 can abut against the main body 300 along the axial direction of the fixing hole 310 to prevent the elastic connecting portion 30 from detaching from the fixing hole 310. It should be noted that when the elastic connecting portion 30 is deformed by force and passes through the fixing hole 310, the second limiting portion 31 can change its position along the first direction so that the elastic connecting portion 30 can smoothly pass through the fixing hole 310. After the external force is withdrawn, the second limiting portion 31 can return to its original position under the restoring force of the elastic connecting portion 30, thereby preventing the elastic connecting portion 30 from detaching from the fixing hole 310. By providing the second limiting portion 31, it is possible to prevent the elastic connecting portion 30 from easily detaching from the fixing hole 310 under the action of an external force, and causing displacement or instability in the fixation of the thermostat 200 relative to the main body 300.

[0054] Furthermore, there are at least two second limiting portions 31, and at least two second limiting portions 31 protrude from both sides of the elastic connecting portion 30 along the first direction. In this way, the abutting and limiting relationship between the second limiting portion 31 and the main body 300 can be made more reliable.

[0055] Specifically, in the embodiments of the present application, the second limiting portion 31 is formed by bending at least a part of the elastic connecting portion 30 outward along the first direction. In this way, the overall structure of the elastic connecting portion 30 can be simplified. Specifically, the cross-sectional shape of the second limiting portion 31 along the first direction is arc-shaped.

[0056] In some embodiments, the elastic connecting portion 30 further includes a transition portion 32 connected between the first limiting portion 11 and the second limiting portion 31. When the elastic connecting portion 30 is elastically clamped in the fixing hole 310, the transition portion 32 can have a radial gap with the fixing hole 310. In this way, after the thermostat fixing structure 100 is fixed in the fixing hole 310, the operation of fixing the thermostat 200 to the thermostat fixing structure 100 can be carried out. Specifically, the transition portion 32 is recessed along the first direction. More specifically, the cross-sectional shape of the transition portion 32 is arc-shaped.

[0057] In the specific actual operation, the operator can apply force to the first clamping arm 10 and the second clamping arm 20 in the direction of approaching each other, so as to cause the elastic connecting portion 30 to deform. At this time, after the elastic connecting portion 30 is inserted into the fixing hole 310, due to the existence of the first limiting portion 11, the thermostat fixing structure 100 cannot move axially any more. At this time, the operator no longer applies force to the first clamping arm 10 and the second clamping arm 20, and under the action of the elastic restoring force, the thermostat fixing structure 100 moves axially, causing the second limiting portion 31 to abut against the edge of the fixing hole 310. At the same time, there is a radial gap between the transition portion 32 and the fixing hole 310. When the thermostat 200 enters the clamping space 40, due to the radial gap between the transition portion 32 and the fixing hole 310, the transition portion 32 can elastically deform, causing the first clamping arm 10 and the second clamping arm 20 to move away from each other, and the thermostat 200 is also clamped in the clamping space 40.

[0058] In order to make the thermostat 200 clamped more stably in the clamping space 40, in some embodiments, one side of the first clamping arm 10 facing the second clamping arm 20 has a first mating surface 12, and the inner profile shape of the first mating surface 12 matches the outer profile shape of the thermostat 200. One side of the second clamping arm 20 facing the first clamping arm 10 has a second mating surface 21, and the inner profile shape of the second mating surface 21 matches the outer profile shape of the thermostat 200. In other embodiments, the first mating surface 12 may also be provided only on the first clamping arm 10, or the second mating surface 21 may be provided only on the second clamping arm 20, which is not limited herein. Specifically, in the embodiments of the present application, the outer shape of the thermostat 200 is cylindrical, and both the first mating surface 12 and the second mating surface 21 are arc-shaped and match it.

[0059] In some embodiments, a first guiding portion 13 is provided at one end of the first clamping arm 10 away from the elastic connecting portion 30. The first guiding portion 13 is inclined away from the second clamping arm 20 along a first direction. Thus, the thermostat 200 can be guided into the clamping space 40. Similarly, a second guiding portion 22 is provided at one end of the second clamping arm 20 away from the elastic connecting portion 30. The second guiding portion 22 is inclined away from the first clamping arm 10 along the first direction. In other embodiments, the first clamping arm 10 and the second clamping arm 20 respectively have the first guiding portion 13 and the second guiding portion 22, which is not limited herein.

[0060] Based on the same inventive concept, the present application also provides a temperature regulating device, including a body 300, a thermostat 200, and the above-mentioned thermostat fixing structure 100.

[0061] Specifically, the temperature regulating device is an oven. More specifically, the body 300 has an inner cavity, and a fixing hole 310 is formed in the side wall of the inner cavity. The oven further includes a heating tube 320, and the heating tube 320 is also fixedly disposed through the side wall of the inner cavity and is located on one side of the fixing hole 310.

[0062] The thermostat fixing structure 100 and the temperature regulating device provided by the embodiments of the present application have the following beneficial effects:

[0063] When it is necessary to install the thermostat 200 on the body 300, the operator can apply force to the first clamping arm 10 and the second clamping arm 20 in the direction of approaching each other, causing the elastic connecting portion 30 to deform. At this time, the elastic connecting portion 30 can be inserted into the fixing hole 310. Thereafter, the operator no longer applies force to the first clamping arm 10 and the second clamping arm 20. At this time, under the action of the elastic restoring force, the elastic connecting portion 30 can be clamped in the fixing hole 310 of the body 300, so as to clamp the thermostat 200 located in the clamping space 40 and keep it in the clamping space 40, so that the thermostat 200 is stably fixed on the body 300 through the thermostat fixing structure 100.

[0064] The thermostat fixing structure 100 and the temperature regulating device of the present application are convenient to operate and do not require additional tools to fix the thermostat 200 on the body 300. Therefore, the fixing efficiency is improved.

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
