Description

Technical Field

[0001] This utility model relates to the technical field of microbiology, specifically to a high-pressure sterilizer with an easy-to-lock lid. Background Technology

[0002] In critical fields of microbial control such as medical treatment, food processing, and biological research, sterilization is essential to thoroughly eliminate pathogenic microorganisms, putrefactive microorganisms, and stubborn spores in the environment or on carriers. This ensures the safety of medical procedures, the shelf life of food, and the accuracy of experimental results. Currently, most autoclaves on the market use single or multiple independent bolts, buckles, or screw-on handles to lock the lid and body. During operation, each locking component must be manually tightened or fastened. This is not only cumbersome and time-consuming, but also prone to uneven force at each locking point, leading to poor sealing between the lid and body and pressure leakage during sterilization. Furthermore, some locking structures lack clear guidance and positioning mechanisms, making it easy for misalignment between the locking components and locking holes to occur during assembly, increasing the difficulty of operation and failing to meet the actual requirements of autoclaves for ease of operation and reliable sealing. Therefore, there is an urgent need for an autoclave with a lid that is easy to lock. Utility Model Content

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes an autoclave body 1 and a lid 2. The lid 2 is abutted at the feed inlet on the upper part of the autoclave body 1. A rubber ring 13 is fixedly installed at the bottom of the lid 2 and abutted at the upper part of the autoclave body 1. The rubber ring 13 has good elasticity. When the lid 2 is pressed down and the rubber ring 13 abuts against the autoclave body 1, the rubber ring 13 will be squeezed and deformed, tightly filling the gap between the lid 2 and the autoclave body 1, preventing the leakage of high temperature and high pressure steam in the autoclave, ensuring that the pressure and temperature in the autoclave reach the standard required for sterilization, thereby ensuring the sterilization effect. It also includes: Vertical rod 3, there are two vertical rods 3, which are fixedly installed on the left and right sides of the upper part of the autoclave body 1 respectively. The upper end of the right vertical rod 3 is rotatably mounted with a rotating frame 4 through a rotating shaft, and the rotating frame 4 is abutted against the upper end of the left vertical rod 3. Handwheel 5, the handwheel 5 is suspended above the rotating frame 4, and a rotating rod 6 is fixedly installed at the bottom of the handwheel 5. The lower end of the rotating rod 6 passes through the rotating frame 4 and is inserted into the pot lid 2 through the bearing. The pot lid 2 is provided with a convenient locking mechanism 7 that is connected to the body 1 of the high pressure sterilizer. Guide rod 8, there are two guide rods 8, which are fixedly installed on the left and right sides of the upper part of the pot lid 2 respectively, and the upper end of the guide rod 8 is movably inserted on the rotating frame 4, and the rotating frame 4 is provided with a positioning mechanism 9; The convenient locking mechanism 7 includes: Rotating disk 7-1, the rotating disk 7-1 is fixedly sleeved on the rotating rod 6, and the rotating disk 7-1 is located inside the pot lid 2. Several arc-shaped grooves 7-2 with equal rounded corners are opened on the rotating disk 7-1, and guide blocks 7-3 are movably arranged in the arc-shaped grooves 7-2. Several fixing rods 7-4 are evenly distributed on the upper part of the autoclave body 1 with equal rounded corners. Reinforcing ribs 12 are fixedly installed on the fixing rods 7-4 and are also fixedly installed on the upper part of the autoclave body 1. The reinforcing ribs 12 can improve the structural strength of the connection between the fixing rods 7-4 and the autoclave body 1, enabling them to better resist the radial and axial forces applied by the insert rods 7-5 during the locking process. Several insert rods 7-5 with equal rounded corners are inserted into the lid 2. Guide blocks 7-3 are fixedly installed on the insert rods 7-5, and one end of each insert rod 7-5 is movably inserted into the fixing rod 7-4. Within the through groove 7-6 on -4, the convenient locking mechanism 7 can simultaneously lock and limit the lid 2 at multiple positions on the autoclave body 1 with a single operation, greatly improving operational efficiency and convenience. An inclined groove 10 is provided above the opening of the through groove 7-6, and one end of the insertion rod 7-5 is provided with a chamfer 11 that cooperates with the inclined groove 10. When the lid 2 is locked onto the autoclave body 1, the cooperation of the inclined groove 10 and the chamfer 11 can force the lid 2 down, ensuring that the rubber ring 13 is evenly compressed, further improving the sealing between the lid 2 and the autoclave body 1. The positioning mechanism 9 includes: A pull rod 9-1 is movably mounted on the rotating frame 4. A handle 9-2 is fixedly mounted on the upper end of the pull rod 9-1, and the lower end of the pull rod 9-1 is movably inserted into the vertical rod 3 on the left side. An abutment plate 9-3 is fixedly sleeved on the pull rod 9-1, and the abutment plate 9-3 is movably mounted in the groove 9-4 opened at the bottom of the rotating frame 4. The abutment plate 9-3 abuts against the upper end of the vertical rod 3 on the left side. Spring 9-5 is fixedly installed in groove 9-4, and the lower end of spring 9-5 is fixedly installed on contact plate 9-3. When it is necessary to lock the lid 2 onto the body 1 of the autoclave, the positioning mechanism 9 can realize the positioning of the rotating frame 4, ensure the accuracy of the alignment between the insertion rod 7-5 and the through groove 7-6, and reduce the difficulty of locking.

[0018] When using this invention, to lock the lid 2, pull the handle 9-2 upwards. The handle 9-2 moves the pull rod 9-1 upwards, and the pull rod 9-1 compresses the spring 9-5 through the contact plate 9-3. Then, rotate the rotating frame 4 to the upper end of the left vertical rod 3, and release the handle 9-2. This causes the spring 9-5 to return to its original position and extend, pushing the contact plate 9-3 downwards. The contact plate 9-3 then moves the pull rod 9-1 downwards and inserts it into the left vertical rod 3, thus positioning the rotating frame 4. Then, rotate the handwheel 5. The handwheel 5, through the rotating rod 6, drives the rotating disk 7-1 to rotate inside the lid 2. The arc groove 7-2 on the rotating disk 7-1 pushes the internal guide block 7-3, causing all the insert rods 7-5 to move synchronously into the pot. The lid 2 moves outward, causing the end of the insertion rod 7-5 to insert into the through groove 7-6 of the corresponding fixing rod 7-4. During insertion, the chamfer 11 at the end of the insertion rod 7-5 slides along the inclined groove 10 above the through groove 7-6. This inclined surface cooperation converts the radial locking force into a downward component force, forcing the lid 2 to move slightly downward, thereby tightly pressing the bottom rubber ring 13 and achieving synchronous and forced sealing of the autoclave. To unlock, simply turn the handwheel 5 in the opposite direction to drive the insertion rod 7-5 to exit the through groove 7-6 synchronously. The lid 2 rises slightly under the rebound force of the rubber ring 13, releasing the seal. Finally, the handle 9-2 can be pulled to unlock the rotating frame 4 and flip it to one side to open the autoclave body 1.

[0019] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. With the convenient locking mechanism 7, all the plug rods 7-5 can be driven to lock synchronously by simply turning the handwheel 5. There is no need to manually operate the locking parts one by one, which greatly simplifies the operation process, shortens the operation time, and significantly improves the efficiency of the autoclave. 2. By utilizing the combination of chamfer 11 and inclined groove 10, the radial force can be converted into a downward component force during the locking process, forcibly pressing down the pot lid 2 to uniformly compress the rubber ring 13, tightly filling the gap between the pot lid 2 and the body, effectively preventing the leakage of high temperature and high pressure steam, and ensuring the pressure and temperature conditions required for sterilization. 3. The positioning mechanism 9, through the cooperation of the pull rod 9-1, the spring 9-5 and the contact plate 9-3, can quickly achieve the positioning and fixation of the rotating frame 4, ensuring that the insertion rod 7-5 and the through groove 7-6 are accurately aligned, avoiding the problem of component misalignment during assembly, reducing the difficulty of locking operation and reducing operational errors; 4. The reinforcing rib plate 12 on the fixing rod 7-4 can enhance its connection strength with the autoclave body 1 and effectively resist the radial and axial forces generated when the insertion rod 7-5 is locked.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
