Description

Technical Field

[0001] This utility model belongs to the technical field of pressure cooker accessories, specifically relating to a folding buckle handle for a pressure cooker. Background Technology

[0002] The widespread use of pressure cookers has placed higher demands on the design of pot handles. An ideal pot handle should possess many advantages, such as convenient operation, reliable locking, and compact structure. However, some existing pressure cooker handle designs still have significant shortcomings.

[0003] Currently, a typical micro-pressure cooker handle on the market uses a double-layered film design with a T-shaped groove as a track. The lid is secured by pushing and pulling the upper film in one direction. While this design is simple, it reveals several flaws in practical use: First, its locking mechanism relies primarily on the displacement of the upper film to hold the lid, providing relatively weak locking force. This makes it difficult to effectively resist the upward force exerted on the lid when the pressure inside the pot increases, posing safety hazards and the risk of incomplete sealing. Second, to accommodate the T-shaped groove and sufficient pushing and pulling stroke, the overall size of the handle is relatively long, wasting valuable kitchen space during storage and contradicting the modern trend of compact and integrated kitchenware design.

[0004] Therefore, there is an urgent need in this field for a new micro-pressure cooker handle solution that is more reliable and more compact in structure to overcome the aforementioned limitations of the prior art. Utility Model Content

[0005] The present invention aims to provide a folding buckle handle for a micro pressure cooker to solve the technical problem of insufficient locking force of existing pot handles leading to sealing failure, while also overcoming the technical problems of their long structure and inconvenient storage.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The folding buckle handle of the pressure cooker includes a fixed base and a handle body. The fixed base has convex shafts on both the left and right sides. The handle body includes a handle part, and two arm plates are connected to the rear side of the handle part. The two arm plates are rotatably mounted on two convex shafts respectively. A locking key is installed in the middle of the fixed base, and a locking groove is provided in the middle of the rear side of the handle to cooperate with the locking key. When the locking key acts on the locking groove, it can restrict the handle body from rotating around the convex axis. A retaining strip also extends from the rear side of the handle. When the handle body is rotated to the pressing position, the retaining strip is used to press the lid of the micro pressure cooker tightly against the outer edge of the top of the pot body.

[0007] Furthermore, the locking key includes a button and a spring. A mounting groove is provided in the middle of the fixing base, and the button and spring are located in the mounting groove. The spring is connected to the inner wall of the button and the mounting groove.

[0008] Furthermore, the cross-section of the convex shaft is oblong, and each arm plate is provided with a guide groove and a circular groove on its side. The guide groove and the circular groove are connected, and the convex shaft slides from the guide groove into the circular groove.

[0009] Compared with existing technologies, the advantages of this invention are as follows: This invention, through the linkage design of "rotational clamping" and "automatic button locking," utilizes the continuous pressure provided by the spring and the hard obstruction of the mechanical locking mechanism to achieve a stable and reliable double locking of the pot lid. This effectively resists the steam pressure inside the pot, fundamentally solving the steam leakage problem caused by insufficient locking force in existing technologies, significantly improving sealing and safety. Secondly, the unique folding structure allows the handle to rotate inwards and retract, greatly reducing the lateral space occupied by the handle, facilitating storage and carrying, and meeting the compact requirements of modern kitchenware.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] The present invention will be further described in detail below with reference to the embodiments.

[0013] like Figure 1-4 As shown, the folding buckle handle of the micro pressure cooker of this utility model is mainly composed of three parts: a fixed base 1, a handle body 2, and a locking key 3. The folding, pressing, and locking functions of the handle are achieved through a clever mechanical structure.

[0014] The fixing base 1 is fixedly installed on the outside of the lid of the pressure cooker by fasteners such as screws or rivets. The fixing base 1 has integrally formed protruding shafts 4 on both its left and right sides, the cross-section of which is preferably oblong. A mounting groove 5 is formed in the middle of the fixing base 1.

[0015] The locking key 3 consists of a button 6 and a spring 7, and is housed in the mounting groove 5 of the fixing base 1. One end of the spring 7 abuts against the inner wall of the mounting groove 5, and the other end provides support for the button 6, so that the button 6 partially protrudes from the mounting groove 5 in its natural state.

[0016] The handle body 2 includes a handle portion 8 for user gripping. Two parallel arm plates 9 are connected to the rear side of the handle portion 8, forming a U-shaped structure that spans across both sides of the fixed base 1. Each arm plate 9 has a guide groove 10 and a circular groove 11 on its side, and the guide groove 10 and the circular groove 11 are interconnected. During assembly, the guide groove 10 on the arm plate 9 is aligned with the convex shaft 4 of the fixed base 1, allowing the convex shaft 4 to slide into the guide groove 10 and finally engage in the circular groove 11. Since the cross-section of the convex shaft 4 is oblong, when it is located in the circular groove 11, it provides axial restraint to prevent the handle body 2 from falling off, while also allowing the handle body 2 to rotate smoothly around the axis of the convex shaft 4. The handle body 2 can rotate around the convex shaft 4 within a range of 0 to 90 degrees, enabling switching between a vertical unfolded position and a horizontal folded position.

[0017] A locking groove 12 is provided in the middle of the rear side of the handle 8. When the user presses down on the handle body 2, rotating it from the folded position to the pressed position, the locking groove 12 will move to a position directly opposite the locking button 3 on the fixing base 1. Under the elastic force of the spring 7, the button 6 will automatically pop out and lock into the locking groove 12, forming mechanical interference, thereby effectively limiting the rotational movement of the handle body 2 caused by the steam pressure inside the pot, and achieving reliable locking.

[0018] A retaining strip 13 extends from the rear side of the handle 8. When the handle body 2 is rotated to the pressed position and locked by the locking key 3, the retaining strip 13 presses precisely against the outer edge of the top of the pressure cooker, thereby pressing the entire lid tightly against the outer edge of the top of the pot. The downward pressure applied by the retaining strip 13 forces the lid sealing ring to deform, thereby achieving a micro-pressure sealing effect inside the pot.

[0019] When it is necessary to open the pot lid, the user only needs to manually press the button 6 of the locking button 3 to overcome the force of the spring 7 and disengage it from the locking groove 12 of the handle part 8, thereby releasing the rotation restriction on the handle body 2. Subsequently, the handle body 2 can be easily rotated back to the folded position under the user's operation, and the locking strip 13 will be lifted, no longer pressing the pot lid, at which point the pot lid can be removed.

[0020] In addition, the handle body 2 can be folded inward independently and flat against both sides of the pot body, which greatly reduces the overall storage space and makes it easy to store.

[0021] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
