Description

Technical Field

[0001] This invention relates to the field of pressure cooker technology, specifically to a clamp-type pressure cooker lid structure. Background Technology

[0002] Pressure cookers can be used to cook a variety of ingredients and are widely used in homes, companies, and school canteens. Their sealing clamp structure allows the pressure inside the pot to increase rapidly in a short time, making food cook faster and more delicious.

[0003] Patent application number CN202121352675.4 discloses a stand-up lid, cookware, and pressure cooker, whose stand-up structure adopts a rack and pinion gear structure. Patent application number CN201820837433.6 discloses a clamp-type pressure cooker, whose internal opening and closing structure is composed of multiple parts and has a relatively complex structure. Patent application number CN201922081952.1 discloses a clamp-type pressure cooker, which uses a toothed gear with a tooth groove to drive the drive plate to move, and is also connected to two springs. The above-mentioned existing products are all stand-up clamp structures, but these structures require many parts and have high manufacturing costs. When one part malfunctions, such as the spring failing after long-term use, it will directly cause the entire structure to be unable to open and close. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a clamp-type pressure cooker lid structure, which is simple in structure, low in cost, easy to operate, long in service life and easier to maintain.

[0005] To solve the above problems, the present invention adopts the following technical solution: A clamp-type pressure cooker lid structure includes a lid body, clamps, a panel, and a vertical plate. The vertical plate is hinged to the panel, and the panel is fixed to the lid body. The clamps are movably disposed between the panel and the lid body. A rotating seat and a movable plate are placed between the panel and the lid body. One end of the vertical plate passes through the movable plate, and the rotating seat passes through the movable plate and the clamps. When the vertical plate is rotated, the movable plate moves left and right, which in turn rotates the rotating seat, causing the clamps to tighten or loosen.

[0006] A further technical solution is that the movable plate is provided with an arc-shaped groove and an oblong hole. The arc-shaped groove is penetrated by a rotating seat, and the oblong hole is penetrated by a vertical plate. A lever on the vertical plate penetrates the oblong hole. When the vertical plate rotates, the lever moves the movable plate, and the movable plate moves left and right inside the panel. The rotating seat, through the arc-shaped groove, drives the clamps to move left and right between the lid body and the panel to tighten or loosen.

[0007] A further technical solution is that the movable plate is provided with two oblong holes, and a limiting post is fixed on the inner side of the panel. The limiting post passes through the two oblong holes, which allows the movable plate to be limited to move laterally in the left and right directions between the pot lid body and the panel, thereby increasing its stability when moving left and right.

[0008] A further technical solution is that there are also three waist-shaped holes distributed on the four corners of the movable plate, and a fixing post is fixed on the inner side of the panel. The fixing post passes through the three waist-shaped holes. After the four fixing posts pass through the four waist-shaped holes, they are connected to the fixing posts with bolts threaded on them. The diameter of the bolt end is greater than the width of the fixing post, so that the movable plate can only move left and right on the fixing post and will not detach from the fixing post, and the distance that the movable plate can move left and right is limited.

[0009] A further technical solution is that the inner side of the panel has protrusions, the limiting post is vertically fixed on the protrusions, the rotating seat is penetrated by the limiting post, the limiting post can rotate around the limiting post axis, and the protrusions can make the rotating seat have a distance from the inner wall of the panel, so that the rotating seat will not interfere with the inner wall of the panel when rotating.

[0010] A further technical solution is that the clamp has four oblong holes and guide slots distributed on it. The four oblong holes are penetrated by a rotating seat. When the rotating seat rotates, the clamp can be moved left and right through the four oblong holes to tighten or loosen the pot body. Guide posts are fixed on the left and right sides of the bottom of the panel. The guide posts penetrate the guide slots. The function of the guide posts is to be locked with lock nuts after penetrating the pot lid body. In this way, the panel and the pot lid body can be fixedly connected. The guide slots and guide posts can play a lateral guiding role when the clamp moves left and right between the panel and the pot lid body, so that the clamp will not deviate.

[0011] A further technical solution is that the rotating seat includes a rotating plate and uprights. The uprights are provided in two and are vertically fixed on both sides of the rotating plate. The two uprights pass through two arc-shaped grooves and simultaneously pass through the waist-shaped holes on the two clamps. In this way, when the rotating plate rotates, it can drive the clamps to tighten or loosen.

[0012] A further technical solution is that a lever is fixed to the side of the connection between the upright plate and the panel, which is used to move the movable plate left and right.

[0013] A further technical solution is that reinforcing ribs are distributed between the actuating rod and the upright plate to increase the strength of the actuating rod.

[0014] A further technical solution is that the panel has grooves distributed on it, and the upright plate, and the connection between the upright plate and the panel, also has flanges distributed on it, which can make the upright plate rotate more smoothly.

[0015] The beneficial effects of this invention are: the clamp-type pressure cooker lid structure of this invention drives the movable plate to move left and right after rotating the upright plate, the movable plate moves left and right to drive the rotating seat to rotate, and the rotating seat to tighten or loosen the clamp. The entire structure involves very few parts compared to pressure cooker products on the market, making it very convenient to operate. At the same time, because there are fewer parts, the manufacturing cost is lower, it is easier to replace parts and maintain them later, and the service life is also longer.

Detailed Implementation

[0019] The preferred embodiments of the present invention will be described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the scope of protection of the present invention.

[0020] See Figures 1 to 12 As shown, a clamp-type pressure cooker lid structure includes a lid body 7, clamps 3, a panel 2, and a vertical plate 1. The vertical plate 1 is hinged to the panel 2, and the panel 2 is fixed to the lid body 7. The clamps 3 are movably disposed between the panel 2 and the lid body 7. A rotating seat 5 and a movable plate 6 are placed between the panel 2 and the lid body 7. One end of the vertical plate 1 passes through the movable plate 6, and the rotating seat 5 passes through the movable plate 6 and the clamps 3. When the vertical plate 1 is rotated, the movable plate 6 moves left and right. The left and right movement of the movable plate 6 causes the rotating seat 5 to rotate, and the rotation of the rotating seat 5 causes the clamps 3 to tighten or loosen.

[0021] The movable plate 6 has an arc-shaped groove 18 and an oblong hole 21. The arc-shaped groove 18 is penetrated by the rotating seat 5, and the oblong hole 21 is penetrated by the upright plate 1. The actuating rod 13 on the upright plate 1 passes through the oblong hole 21. When the upright plate 1 rotates, the actuating rod 13 actuates the movable plate 6, causing the movable plate 6 to move left and right within the panel 2. The rotating seat 5, passing through the arc-shaped groove 18, drives the clamp 3 to move left and right between the lid body 7 and the panel 2 to tighten or loosen the clamp. The movable plate 6 also has an oblong hole 19. A limiting post 17 is fixed inside the panel 2, passing through the oblong hole 19. This allows the movable plate 6 to be limited to lateral movement between the lid body 7 and the panel 2, increasing its stability during left and right movements. The movable plate 6 has four oblong holes 20 at its four corners. A fixing post 16 is fixed to the inner side of the panel 2, passing through the oblong holes 20. The four fixing posts 16 are threaded onto the fixing posts 16 with bolts. The diameter of the bolt end is larger than the width of the fixing post 16, ensuring that the movable plate 6 can only move left and right on the fixing posts 16 without detaching from them, and limiting the lateral movement distance of the movable plate 6. A boss 15 is distributed on the inner side of the panel 2, and a limiting post 17 is vertically fixed to the boss 15. The rotating seat 5 is penetrated by the limiting post 17, allowing the limiting post 17 to rotate axially around it. The boss 15 ensures that there is a distance between the rotating seat 5 and the inner wall of the panel 2, preventing interference between the rotating seat 5 and the inner wall of the panel 2 during rotation.

[0022] The clamp 3 has oblong holes 4 and guide slots 8. The oblong holes 4 are penetrated by the rotating seat 5. When the rotating seat 5 rotates, the clamp 3 can move left and right through the oblong holes 4 to tighten or loosen the pot body. Guide posts 9 are fixed on the left and right sides of the bottom of the panel 2. The guide posts 9 penetrate the guide slots 8. The function of the guide posts 9 is to pass through the pot lid body 7 and lock it with the locking nut 22. In this way, the panel 2 and the pot lid body 7 can be fixedly connected. The guide slots 8 and guide posts 9 can provide lateral guidance when the clamp 3 moves left and right between the panel 2 and the pot lid body 7, so that the clamp 3 will not deviate. The rotating seat 5 includes a rotating plate 51 and uprights 52. There are two uprights 52, which are vertically fixed on both sides of the rotating plate 51. The two uprights 52 pass through two arc-shaped slots 18 and also pass through the oblong holes 4 on the two clamps 3. In this way, when the rotating plate 51 rotates, it can tighten or loosen the clamp 3. A lever 13 is fixed to the side of the connection between the upright plate 1 and the panel 2, which is used to move the movable plate 6 left and right. Reinforcing ribs 14 are also distributed between the lever 13 and the upright plate 1 to increase the strength of the lever 13. The panel 2 has slots 10, and the upright plate 1, located at the connection between the upright plate 1 and the panel 2, also has flanges 23, which can make the rotation of the upright plate 1 smoother.

[0023] In this embodiment, when the lid needs to be tightened or loosened on the pot body, a connecting block 11 is provided on the panel 2, located outside the flange 23. The connection end between the upright plate 1 and the panel 2 is hinged through a rotating shaft 12. That is, after the upright plate 1 is inserted into the connecting block 11, the rotating shaft 12 is inserted to achieve a rotatable connection with the panel 2. After the rotating shaft 12 is inserted, it passes through the connecting block 11 and finally is press-fitted or threadedly connected to the upright plate 1. Then, the upright plate 1 is rotated, and the actuating rod 13 at the end of the upright plate 1 moves the movable plate 6, causing the movable plate 6 to move left and right within the panel 2. The left and right movement of the movable plate 6 causes the arc groove 18 to press against the upright rod 52 on the rotating seat 5, and causes the rotating seat 5 to rotate along the central axis. The upright rod 52 passes through the waist-shaped hole 4 on the clamp 3, and finally causes the clamp 3 to move left and right between the panel 2 and the pot lid body 7 to tighten or loosen the pot body. And when the upright plate 1 rotates, as Figure 12 As shown, it can stand upright on a plane.

[0024] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without creative effort should be covered within the scope of protection of the present invention.
