Description

Technical Field

[0001] This utility model relates to the field of vacuum pressure vessel technology, and in particular to an easy-open vacuum pressure vessel. Background Technology

[0002] A vacuum pressure tank is a device that uses the compressibility of air inside the tank to regulate and store water volume and maintain the required pressure. When opening a pressure tank, the pressure must be released first, and then the lid must be opened. Although the pressure has been released, there is still a "residual" pressure difference between the lid and the tank body. In other words, the tank body still exerts a suction force on the lid. Furthermore, there is no assist structure on the pressure tank. In addition, the lid itself is heavy, making it very difficult for users to open the lid, especially for large pressure tanks. This requires users to exert a lot of force to open the lid, slowing down the opening speed and causing inconvenience for users.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a pusher structure set on the side of the tank. After the can lid is unlocked, the pusher structure first pushes the can lid to unfold from the tank body, eliminating the suction force generated by the pressure difference that restricts the can lid, providing assistance to the user in opening the pressure tank. Then the user can open the pressure tank more effortlessly, quickly and easily, providing more convenience for the user in using the pressure tank.

[0014] 2. The limiting slide rod and limiting slide groove of this utility model are designed so that when the toothed plate is pushed to slide, the limiting slide rod will also slide in the limiting slide groove.

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0027] An easy-open vacuum pressure vessel includes a vessel body 1. A shell 2 is provided on one side of the surface of the vessel body 1. A stepper motor 7 is fixedly installed at the bottom of the inner cavity of the shell 2. A special-shaped gear 8 is fixedly installed on the output shaft of the stepper motor 7. A sliding cavity 3 is opened on one side of the inner cavity of the shell 2. A pusher tooth plate 4 located inside the shell 2 is slidably installed in the inner cavity of the sliding cavity 3. The pusher tooth plate 4 meshes with the special-shaped gear 8. A baffle 5 that slides inside the sliding cavity 3 is fixedly installed on one side of the pusher tooth plate 4. A spring 6 is fixedly connected to one side of the baffle 5. The end of the spring 6 away from the baffle 5 is fixedly connected to the inner wall of the sliding cavity 3. An adapter block 13 is provided on one side of the shell 2.

[0028] The specific usage process is as follows: A booster structure is installed on the side of the tank body 1. This booster structure is used to push the tank cover 17, reducing the resistance to opening the tank cover 17 and providing more assistance to the user in opening the tank cover 17, ensuring that the user can open the pressure tank more easily. This booster structure consists of a pusher plate 4, a baffle 5, a spring 6, a stepper motor 7, a special gear 8, a limit slide bar 9, and other transmission structures. During use, the pressure tank is first depressurized according to regulations. After the pressure inside the tank reaches a safe value, the stepper motor 7 is started. The stepper motor 7 will drive the special gear 8 to rotate. The special gear 8 will drive the pusher plate 4 to move inside the outer shell 2. Finally, under the push of the pusher plate 4, the adapter block 1 will be pushed. 3. When the can is pushed open, the adapter block 13 will move the secondary lock 16 away. Finally, the secondary lock 16 will move the can lid 17 away from the can body 1. With the assistance of mechanical power, the suction force generated by the can body 1 on the can lid 17 can be canceled out, and the can lid 17 can also be pushed open partly. At this time, it is more convenient and less effort for the user to manually open the can lid 17. Then the user can continue to open the can lid 17 outwards. By reducing the resistance of the can body 1 on the can lid 17, the user can complete the opening of the can lid 17 more quickly, providing convenience for the user's work. Among them, the pushing toothed plate 4 will simultaneously drive the baffle 5 and the limiting slide bar 9 to move together. The limiting slide bar 9 is also in The outer casing 2 slides within the sliding cavity 3, while the limiting slide rod 9 also slides within the limiting groove 10. In this way, the outer casing 2 can limit the movement of the pushing gear plate 4, ensuring the stability of its movement and guaranteeing that the pushing gear plate 4 always meshes with the non-circular gear 8. The limiting groove 10, in turn, limits the movement of the limiting slide rod 9, ensuring its stability and further limiting the movement of the pushing gear plate 4. Simultaneously, the baffle 5 also moves within the sliding cavity 3 and moves along with the pushing gear plate 4, compressing the spring 6. After the can lid 17 is opened, and after the irregular gear 8 and the push tooth plate 4 are temporarily disengaged, the baffle 5 will be pushed back to its original position under the action of the spring 6. Then the baffle 5 will drive the push tooth plate 4 to reset for the next use. When the push tooth plate 4 resets, it will also drive the limiting slide rod 9 to slide and reset in the limiting slide groove 10, which also plays a limiting role in the reset work of the push tooth plate 4, ensuring the smooth operation of the push tooth plate 4 and providing convenience for the user. It should be noted that there is a part of the surface of the irregular gear 8 without teeth, so there will be a gap in the meshing transmission with the push tooth plate 4, so that the push tooth plate 4 can be quickly reset by the spring 6.

[0029] Therefore, a booster structure is installed on the side of the tank. After the lid is unlocked, the booster structure pushes the lid off the tank, eliminating the suction force generated by the pressure difference that restricts the lid. This provides assistance to the user in opening the pressure tank, allowing the user to open the pressure tank more easily, quickly, and conveniently.

[0030] A limiting slide rod 9 is fixedly connected to one side of the push tooth plate 4, and a limiting slide groove 10 adapted to the limiting slide rod 9 is provided on one side of the inner cavity of the outer shell 2.

[0031] Specifically, the limiting slide rod 9 and the limiting slide groove 10 are designed so that when the toothed plate 4 is pushed to slide, the limiting slide rod 9 will also slide within the limiting slide groove 10. In this way, the limiting slide rod 9 and the limiting slide groove 10 work together to limit the movement of the toothed plate 4, ensuring the stability of the toothed plate 4 during its movement.

[0032] A positioning groove 11 is provided on one side of the outer shell 2, and a positioning block 12 fixed on the tank body 1 is slidably installed in the inner cavity of the positioning groove 11.

[0033] Specifically, the positioning groove 11 and the positioning block 12 are set up such that the positioning block 12 is fixedly connected to the tank body 1, and when installing the outer shell 2, it is necessary to ensure that the positioning block 12 is inserted into the positioning groove 11 on the outer shell 2. This can limit the outer shell 2 and also help the installation of the outer shell 2, ensuring that the subsequent installation of bolts is smoother and more accurate, thus providing convenience for the user's installation work.

[0034] The positioning block 12 has a main locking component 14 located on the outside of the outer shell 2 on one side. The outer shell 2 is detachably mounted on the main locking component 14. The main locking component 14 is fixedly mounted on the tank body 1. The adapter block 13 has a secondary locking component 16 that is adapted to the main locking component 14 fixedly connected to one side.

[0035] Specifically, the main locking component 14 and the auxiliary locking component 16 are combined to form a lock for the pressure tank, used to lock the tank cover 17. This is existing technology, and the specific details will not be elaborated in the text. For details, please refer to the existing pressure tank lock structures on the market to ensure the normal operation of the pressure tank and provide convenience for users.

[0036] Multiple guide blocks 15 are fixedly installed on the top and bottom of the main locking component 14, and one side of the auxiliary locking component 16 extends between the upper and lower guide blocks 15.

[0037] Specifically, the guide blocks 15, with four guide blocks 15 distributed vertically, can guide and limit the opening and closing of the secondary lock 16. When the secondary lock 16 is connected to the main lock 14, it can accurately guide the secondary lock 16 and provide support for the secondary lock 16, ensuring the tightness and stability of the connection between the secondary lock 16 and the main lock 14, thus providing convenience for the user's work.

[0038] One end of the tank body 1 is provided with a tank cover 17, the auxiliary locking member 16 is fixedly installed on the tank cover 17, and a movable corner block 18 is fixedly installed on one side of the tank cover 17. The tank cover 17 is movably installed on the tank body 1 through the movable corner block 18.

[0039] Specifically, regarding the can lid 17 and the movable corner block 18, one end of the movable corner block 18 is fixedly connected to the can lid 17, and the other end is movably installed on the can body 1. In this way, the can lid 17 can be opened and closed by being movably installed on the can body 1 through the movable corner block 18, just like a hinge, thus providing convenience for users to open the can lid and for users to use it.

[0040] A sealing ring 19 is fixedly installed on one side of the can lid 17. The sealing ring 19 is inserted into the inside of the can body 1. Support blocks 20 are fixedly connected to both sides of the bottom of the can body 1.

[0041] Specifically, the sealing ring 19 and the supporting base block 20 are designed such that the supporting base block 20 is located at the bottom of the tank body 1 to support the tank body 1, thereby lifting the tank body 1 off the ground, preventing the tank body 1 from getting damp and rusted, and extending the service life of the supporting base block 20. The sealing ring 19 is fixed on the tank cover 17. When the tank cover 17 is closed, the sealing ring 19 will extend into the tank body 1, which can play a positioning role for the tank cover 17, preventing the tank cover 17 from moving freely, and also play a sealing role for the closure of the tank cover 17 and the tank body 1, ensuring the sealing performance of the pressure tank and providing convenience for users.

[0042] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
