Description

Technical Field

[0001] This utility model relates to the field of steamer lid technology, and in particular to a rotary pressing steamer lid that can be quickly opened and closed. Background Technology

[0002] In food processing (such as liquor distillation, grain cooking, and traditional Chinese medicine extraction) and chemical refining, the still pot is a core piece of equipment. The efficiency of opening and closing the lid and the reliability of the seal directly affect the continuity of the production process and the quality of the product. Traditional still pot lids mostly rely on manual or simple mechanical operation. It is necessary to ensure that the high-temperature steam inside the still does not leak out and to maintain a stable process pressure while achieving convenient opening and closing of the lid. Especially in intermittent production scenarios (such as liquor brewing where each batch of distillation requires multiple openings of the lid to add and remove materials, and traditional Chinese medicine extraction where the cooking status of materials needs to be checked regularly), the need for "rapid opening and closing" of the lid is even more urgent.

[0003] Currently, the mainstream steamer lid opening and closing technologies in the industry are mostly based on the design concept of "manual mechanical transmission" or "single power drive". From the perspective of mechanical structure, common solutions include: First, "bolt fastening structure", that is, 4 to 8 bolt holes are evenly distributed around the edge of the steamer lid, and bolt seats are set at the upper opening of the steamer body. When closing, the bolts need to be manually passed through the holes of the lid and the seat of the steamer body one by one and tightened. The axial pressure of the bolts makes the lid sealing gasket fit against the steamer body. Second, "lever-driven structure", long-handled levers are installed on both sides of the steamer lid. The ends of the levers are hinged to the brackets at the bottom of the steamer body. When closing, the levers are manually pressed down, and the lid is pressed against the steamer body by lever principle. Some solutions will be equipped with 1 to 2 positioning pins to prevent the lid from shifting. In essence, all of them require multiple steps to build the sealing pressure between the lid and the steamer body to ensure that steam does not leak out.

[0004] In existing technologies, the "bolt-fastening" and "lever-operated" structures have significant problems with low opening and closing efficiency. Taking a medium-sized steamer with a diameter of 1 meter as an example, when using the bolt-fastening structure, tightening 8 bolts manually requires one operation at a time, and each bolt needs to be rotated 5-8 times to reach the sealing pressure, which takes about 2-3 minutes. Even with the lever-operated structure, although there is no need to repeatedly tighten the bolts, in order to ensure reliable sealing, the lever angle needs to be adjusted manually and pressed into place multiple times. Moreover, the operating force of a single lever is relatively large, which is difficult for a single person to complete quickly. If frequent opening and closing is required, it will greatly increase the labor intensity of manual labor and prolong the production interval time, affecting the overall production efficiency. Therefore, a rotary pressing steamer lid that can be opened and closed quickly is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary pressing pot lid that can be opened and closed quickly. It aims to improve the problem that the locking structure of the pot lid in the prior art requires "multi-step, long-stroke" operation, resulting in low opening and closing efficiency, high manual labor intensity, and inability to meet the "quick opening and closing" requirements of intermittent production scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary pressing steamer lid that can be quickly opened and closed includes a pot body and a connecting pipe. The pot body is rotatably connected to the lid, the top of the lid is fixedly connected to a handle, the top of the lid is fixedly connected to a steam pipe, and the side wall of the pot body is provided with a locking component.

[0008] The locking assembly includes a fixing frame fixedly connected to the outer wall of the pot body. A locking rod is rotatably connected inside the fixing frame. A snap fastener is fixedly connected to the side wall of the pot lid and engages with the locking rod. A support plate is fixedly connected to one side of the locking rod. A sliding shaft is slidably connected inside the support plate. A snap-fit ​​post is fixedly connected to one end of the sliding shaft and engages with a groove inside the fixing frame. A spring is sleeved on the outer wall of the sliding shaft. One end of the spring is fixedly connected to the side wall of the support plate, and the other end is fixedly connected to the side wall of the snap-fit ​​post. A connecting assembly is provided on the outer wall of the steam pipe.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a connecting ring and a connecting plate, both of which are slidably connected to the outer wall of the steam pipe, and the connecting ring is rotatably connected to the side wall of the connecting plate.

[0011] As a further description of the above technical solution:

[0012] A second connecting ring is rotatably connected to the other side of the connecting plate, and a sealing ring is fixedly connected to the bottom of the connecting pipe.

[0013] As a further description of the above technical solution:

[0014] The sealing ring contacts the top of the steam pipe, and a connecting bracket is fixedly connected to one side of the connecting ring.

[0015] As a further description of the above technical solution:

[0016] The connecting frame is rotatably connected to a transmission frame, and a support block is fixedly connected to one side of the connecting ring.

[0017] As a further description of the above technical solution:

[0018] The support block is rotatably connected to a fixed plate, and the outer wall of the transmission frame is rotatably connected to the inside of the fixed plate.

[0019] As a further description of the above technical solution:

[0020] A lever is fixedly connected to the outer wall of the fixing plate. The lever is in the shape of an inclined panel and is made of hard rubber.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pulling the sliding shaft to make it slide inside the support plate, the locking column is driven to move. When the locking column moves, it will disengage from the fixed frame to achieve quick unlocking, thereby achieving the effect of quickly unlocking the pot lid. This solves the problem of low opening and closing efficiency caused by the need for multiple steps in the locking structure of the pot lid in the prior art, and improves the opening and closing efficiency of the pot lid and the overall operating efficiency of the equipment in intermittent production scenarios.

[0023] 2. In this utility model, by attaching the connecting pipe to the steam pipe, and by moving the lever to make the connecting ring one and the connecting ring two press towards the center simultaneously, the effect of quickly connecting the steam pipe is achieved. This solves the problem that the existing steam pipe connection of the pot requires multiple steps for alignment and tightening, which leads to long connection time and easily affects the stability of the process inside the pot due to connection delay. This improves the connection efficiency of the pot steam system. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a rotary pressing pot lid that can be quickly opened and closed, including a pot body 1 and a connecting pipe 5. A pot lid 2 is rotatably connected inside the pot body 1. A handle 3 is fixedly connected to the top of the pot lid 2. The handle 3 has a U-shaped structure, and its two ends are firmly connected to the top surface of the pot lid 2 by welding. The height and spacing of the handle 3 are ergonomically designed to ensure that the operator can exert force smoothly when holding it and avoid direct contact between the hand and the hot surface of the pot lid 2 when opening the lid. A steam pipe 4 is fixedly connected to the top of the pot lid 2. The steam pipe 4 has a cylindrical hollow structure. Its lower end vertically penetrates the pot lid 2 and communicates with the inside of the pot lid 2. The connection is sealed by welding to prevent steam from leaking from the gap. The upper end of the steam pipe 4 extends to the top of the pot lid 2 for docking with external pipes or equipment. A locking component is provided on the side wall of the pot body 1 to realize the quick locking and unlocking of the pot lid 2.

[0033] The locking assembly includes a fixing frame 7, which is fixedly connected to the outer wall of the pot body 1 and has an L-shaped structure. Its vertical section is fixedly connected to the preset mounting hole on the outer wall of the pot body 1 by bolts, and its horizontal section extends towards the center of the pot body 1. The end of the horizontal section is machined with a circular through hole. A locking rod 8 is rotatably connected inside the fixing frame 7. The locking rod 8 is a cylindrical long rod structure. Its rod body is rotatably connected to the circular through hole in the horizontal section of the fixing frame 7 through a bearing, so that the locking rod 8 can rotate freely around its own axis. At the same time, one end of the locking rod 8 extends to the side of the pot lid 2, and the other end extends outward from the fixing frame 7, which is convenient for the operator to rotate and operate.

[0034] A latching buckle 6 is fixedly connected to the side wall of the pot lid 2. The latching buckle 6 has a U-shaped block structure, with its opening facing the locking rod 8. The width of the internal groove of the latching buckle 6 matches the diameter of the locking rod 8. When the pot lid 2 is closed, rotating the locking rod 8 allows the rod body of the locking rod 8 to engage with the internal groove of the latching buckle 6, initially locking the pot lid 2 and the pot body 1. The latching buckle 6 engages with the locking rod 8. A support plate 9 is fixedly connected to one side of the locking rod 8. A sliding shaft 10 is slidably connected inside the support plate 9. One end of the sliding shaft 10 is fixedly connected to a latching post 11. The latching post 11 fits into the internal slot of the fixing frame 7, locking... The locking column 11 is cylindrical, and its diameter matches the diameter of the pre-set slot on the horizontal section of the fixing frame 7. When the locking rod 8 rotates to the locking position in the locking buckle 6, pushing the sliding shaft 10 can insert the locking column 11 into the slot of the fixing frame 7, thereby restricting the rotation of the locking rod 8 and preventing the locking rod 8 from accidentally loosening after locking. A spring 12 is sleeved on the outer wall of the sliding shaft 10. One end of the spring 12 is fixedly connected to the side wall of the support plate 9, and the other end of the spring 12 is fixedly connected to the side wall of the locking column 11. A connecting component is provided on the outer wall of the steam pipe 4, which is a key structure for realizing the quick sealing connection between the steam pipe 4 and the connecting pipe 5.

[0035] Reference Figure 4 and Figure 5 The connecting assembly includes a connecting ring 13 and a connecting plate 14, both of which are annular structures. Both are slidably connected to the outer wall of the steam pipe 4, allowing them to slide up and down along the axis of the steam pipe 4. Simultaneously, the connecting ring 13 is rotatably connected to the lower side wall of the connecting plate 14 via an annular bearing, meaning the connecting plate 14 can move up and down synchronously with the sliding of the connecting ring 13. Furthermore, the connecting plate 14 can rotate freely around the axis of the connecting ring 13, facilitating the adjustment of the position of subsequent components. Both the connecting ring 13 and the connecting plate 14 are slidably connected to the outer wall of the steam pipe 4. The connecting ring 13 is rotatably connected to the side wall of the connecting plate 14. The connecting ring 15 is rotatably connected to the other side of the connecting plate 14. The bottom of the connecting pipe 5 is fixedly connected to the sealing ring 21. The sealing ring 21 is an annular elastic structure with an outer diameter slightly smaller than the outer diameter of the connecting pipe 5. The lower surface of the sealing ring 21 is in contact with the end face of the top of the steam pipe 4. When the connecting pipe 5 and the steam pipe 4 are connected, the sealing ring 21 is compressed, thereby filling the gap between the two and achieving a seal.

[0036] The sealing ring 21 contacts the top of the steam pipe 4. A connecting frame 16 is fixedly connected to one side of the connecting ring 2 15. A transmission frame 17 is rotatably connected inside the connecting frame 16. A support block 18 is fixedly connected to one side of the connecting ring 13. The support block 18 is a block structure with a U-shaped groove machined on its top. The fixing plate 19 is rotatably connected to the U-shaped groove of the support block 18 by a pin, so that the fixing plate 19 can be rotated around the pin. The fixing plate 19 is rotatably connected inside the support block 18. The outer wall of the transmission frame 17 is rotatably connected to the inside of the fixing plate 19. A lever 20 is fixedly connected to the outer wall of the fixing plate 19. The lever 20 is in the shape of an inclined plate, and its inclination direction is adapted to the rotation direction of the fixing plate 19. The operator can turn the lever 20 by using a hard rubber material.

[0037] Working principle: When using this quick-opening and closing rotary pressing pot lid, firstly, the user places the lid 2 against the pot body 1. Then, by rotating the lid 2, it is rotatably connected to the pot body 1 through the threaded action. Simultaneously, by pulling the sliding shaft 10, it slides inside the support plate 9, thereby causing the locking pin 11 to disengage from the fixing frame 7 and unlock. Then, the locking lever 8 is moved to engage with the locking buckle 6 on the outer wall of the lid 2. At the same time, the force of pulling the sliding shaft 10 is released, and the elastic restoring force of the spring 12 pushes the locking pin... The retaining column 11 is re-engaged into the fixing frame 7 to achieve locking, thus providing convenient operation for the user when opening and closing the pot lid 2. When it is necessary to connect the steam pipe 4 and the connecting pipe 5, the user can press the steam pipe 4 and the connecting pipe 5 together. The sealing ring 21 can ensure the sealing of the connection. Then, by moving the lever 20, it drives the connecting ring 13 and the connecting ring 25 to be squeezed towards the center at the same time to deform and fit tightly with the connection of the steam pipe 4 and the connecting pipe 5, thereby achieving the effect of quickly connecting the steam pipe 4 and the connecting pipe 5.
