Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat preservation and heating devices, and in particular to a hinge for a steam pressure cooker. Background Technology
[0002] Existing steam pressure cookers typically have separate pot bodies and lids. Because the lids are quite thick, the pot body and lid are usually separate components. Once the lid is opened, it completely separates from the pot body, requiring a large area to place, which is very inconvenient. Utility Model Content
[0003] To address the aforementioned technical problems in the background art, this utility model provides a hinge for a steam pressure cooker, used to connect the pot body and the lid. When the lid is opened, it does not detach from the pot body, making it convenient to use.
[0004] The technical solution of this utility model is as follows: This utility model is a hinge for a steam pressure cooker, which is special in that: the hinge for the steam pressure cooker includes a hinge frame and a hinge connected to each other. One end of the hinge frame is connected to the pot lid, and the hinge is set on the upper part of the pot body. The end of the hinge connected to the hinge frame is provided with a protrusion. A hinge shaft is provided on both sides of the protrusion. The end of the hinge frame connected to the hinge is provided with a groove. The protrusion is engaged in the groove. On both sides of the groove, corresponding to the position of the hinge shaft, there are waist-shaped holes. The outer ends of the two hinge shafts are respectively inserted into the waist-shaped holes.
[0005] Furthermore, the contact surfaces at the bottom of the groove and the sides of the bottom of the protrusion are arc surfaces that are lower in the front and higher in the back.
[0006] Furthermore, the hinge frame is U-shaped, and a lid locking ring that can rotate relative to the lid is provided on the outside of the lid, with one side of the lid locking ring located inside the U-shaped hinge frame.
[0007] Furthermore, the hinge shaft is machined onto the hinge and is an integral part of the hinge structure.
[0008] This utility model provides a hinge for a steam pressure cooker. The hinge frame and hinges are connected to the pot body and lid respectively. The hinge shaft and oblong hole allow for adjustment of the distance between the hinge frame and the hinge, thus adjusting the distance between the lid and the pot body. This ensures sufficient clearance at the connection point, allowing the lid to open or close along one side of the pot body. The contact surfaces at the bottom of the groove and the sides of the protrusion are arc-shaped surfaces, lower in the front and higher in the back. When the lid is open, the arc surfaces interact, and the gap between the oblong hole and the lid naturally lifts it. When the lid is closed, the arc surfaces interact again, and the lid naturally lowers, making opening and closing convenient. Attached Figure Description

[0011] The annotations in the attached figures are explained as follows:
[0012] 1. Lid locking ring; 2. Pot body; 3. Hinge frame; 4. Groove; 5. Protrusion; 6. Hinge shaft; 7. Waist-shaped hole; 8. Hinge. Detailed Implementation
[0013] The overall scheme of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0014] See Figure 1 , 2 In a specific embodiment of this utility model, one side of the pot lid is connected to the pot body via a hinge frame 3 and a hinge 8. A protrusion 5 is provided at the end where the hinge 8 connects to the hinge frame 3, and hinge shafts 6 are respectively provided on both sides of the protrusion 5. A groove 4 is provided at the end where the hinge frame 3 connects to the hinge 8, and the protrusion 5 is engaged in the groove 4. Waist-shaped holes 7 are respectively provided on both sides of the groove 4 corresponding to the positions of the hinge shafts 6. The outer ends of the two hinge shafts 6 are respectively inserted into the waist-shaped holes 7. The contact surfaces between the bottom of the groove 4 and the bottom sides of the protrusion 5 are arc-shaped surfaces that are lower in the front and higher in the back. The hinge shafts 6 are circumferentially fitted with the gaps in the waist holes, and also fit with the arc-shaped surfaces of the bottom of the groove 4 and the upper and lower contact surfaces of the bottom of the protrusion 5. When the pot lid is opened, the arc-shaped surfaces interact to lift the pot lid. The hinge shafts 6 on the hinge 8 are actually machined onto the hinge 8 and are integral with it.
[0015] In a preferred embodiment of this utility model, the steam pressure cooker includes a lid and a pot body 2. The lid is mounted on the pot body 2, and a lid locking ring 1 is located on the outer side of the lid. The center of the lid locking ring 1 and the center of the lid are movably connected by a top bolt, allowing the lid locking ring 1 to rotate relative to the lid via the top bolt. The hinge frame 3 is U-shaped, with one side of the lid locking ring 1 located inside the U-shaped hinge frame 3. An annular outer protrusion is provided on the outer side of the pot opening of the pot body 2, with outer protrusions spaced apart on the annular outer protrusion. An inner protrusion is provided on the inner side of the lower end of the lid locking ring 1, corresponding to the outer protrusions, spaced apart. By rotating the lid locking ring 1, the inner protrusion can be engaged below the outer protrusions. When the lid is closed, the inner protrusion at the lower end of the lid locking ring 1 is engaged in the gap between the outer protrusions. The lid locking ring 1 is equipped with a handle. Rotating the handle clockwise causes the lid locking ring 1 to rotate, and the inner protrusion at the lower end of the lid locking ring 1 screws into the lower part of the outer protrusion, locking the lid. When the lid is opened, rotating the lid locking ring 1 in the opposite direction causes the inner protrusion to disengage from the outer protrusion and be positioned in the gap between the outer protrusions, allowing the lid to be opened.
[0016] When the lid is opened, the lid is naturally lifted by the interaction of the hinge shaft 6 and the oblong hole 7, as well as the interaction of the arc surfaces of the bottom of the groove 4 and the bottom of the protrusion 5. When the lid is closed, the lid naturally moves down by the interaction of the hinge shaft 6 and the oblong hole 7, as well as the interaction of the arc surfaces of the bottom of the groove 4 and the bottom of the protrusion 5. The lid is easy to open and close.
[0017] The content of this utility model and the technical content not specifically described in the above embodiments are the same as the prior art.
[0018] The above are merely specific embodiments disclosed in this utility model, but the scope of protection disclosed in this utility model is not limited thereto. The scope of protection disclosed in this utility model shall be determined by the scope of protection of the claims.
