Description

Technical Field

[0001] The utility model provides a radiation-proof can, belonging to the technical field of radioactive drug storage equipment, and particularly relates to a radiation-proof can with an easily openable lid. Background Art

[0002] Radioactive drugs refer to drugs containing radioactive isotopes, which are used for radionuclide scanning, treatment or diagnosis. They mainly include radioactive isotope drugs and radioactive labeled drugs. The storage of radioactive drugs should comply with relevant regulations and guidelines. Generally, radioactive drugs should be stored in specific radioactive drug storage rooms, which must meet strict safety standards, such as having lead shielding to reduce radiation and having an appropriate ventilation system, etc.

[0003] When it is necessary to take out the radiation-proof can, medical staff need to wear protective gloves, place the radioactive drugs in the shielding workbench, and then open the storage can of the drugs. Currently, the sealing methods of existing storage cans are mostly integrated sealing connections or connections with the help of other structures such as bolt interfaces and buckle structures. It is inconvenient for medical staff to open, time-consuming and laborious. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the embodiments of the present application provide a radiation-proof can with an easily openable lid, which solves the problem that the lid of the storage can of radioactive drugs in the prior art is not easy to open.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a radiation-proof can with an easily openable lid, including a storage can, a sealing lid structure is arranged above the storage can, the sealing lid structure includes a sealing ball placed above the storage can, a regulating air valve is connected above the sealing ball through a main spring, and an air release valve is arranged on one side of the regulating air valve and penetrates through the sealing structure.

[0006] Preferably: an air valve pipe is sleeved outside the sealing ball and is placed inside the sealing lid structure and corresponds to the main spring, and an inclined surface corresponding to the sealing ball is arranged at one end of the air valve pipe close to the sealing ball.

[0007] Preferably: the regulating air valve includes an air valve seat placed inside the air valve pipe and fixedly connected to one end of the main spring away from the sealing ball, and an air valve plate penetrated by the connecting rod is connected between the air valve seats through uniformly distributed connecting rods.

[0008] Preferably: a piston plate is arranged on the side of the air valve plate away from the storage can and is placed inside itself, the diameter of the piston plate is larger than that of the air valve seat and corresponds to the air valve pipe, and a tension spring is arranged below the piston plate and is fixedly connected to the air valve plate inside the air valve plate.

[0009] Preferably: one end of the air valve pipeline away from the storage tank is connected to a T-shaped pressing plate through a pressing spring, the pressing plate is placed in the sealing cover structure, and arc-shaped vents placed in the sealing cover structure are arranged around the pressing plate.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] The utility model provides a sealing cover structure placed above the storage tank, and drives the sealing ball to move up and down with the help of a main spring inside the sealing cover structure. When the regulating air valve is pressed down, the main spring is driven downward to drive the sealing ball to support the bottom air outlet of the sealing cover structure. The internal gas regulating air valve in the sealed space increases with the regulating air valve downstream, and the air pressure increases and passes through the regulating air valve to the outside. After the regulating air valve is loosened, the internal air is emptied, the sealing ball leaves the air outlet, and the gas inside the storage tank enters the sealing cover structure. After repeating the above operation until most of the gas in the tank is discharged, the internal and external pressures make the sealing cover structure support the storage tank to achieve sealing. However, when the tube body needs to be opened, the air release valve is opened to balance the air pressure, and the sealing cover structure can be easily opened.

[0012] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and study, or may be taught from the practice of the present invention to some extent.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific implementation manners and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] As Figure 1 and Figure 2 shown, a radiation-proof can with an easily openable lid body includes a storage tank 1, and is characterized in that: a sealing cover structure 2 is provided above the storage tank 1, and the sealing cover structure 2 includes a sealing ball 21 placed above the storage tank 1. An air valve pipeline 12 corresponding to the main spring 22 is sleeved outside the sealing ball 21 and is placed inside the sealing cover structure 2. An inclined plane 13 corresponding to the sealing ball 21 is provided at one end of the air valve pipeline 12 close to the sealing ball 21. An adjusting air valve 23 is connected above the sealing ball 21 through the main spring 22, and an air release valve 11 penetrating the sealing structure 2 is provided on one side of the adjusting air valve 23.

[0027] In this implementation scheme, by setting the seal cover structure 2 above the storage tank 1, the main spring 22 inside the seal cover structure 2 drives the seal ball 21 to move up and down. When pressing the regulating air valve 23, the main spring 22 is pressed down to drive the seal ball 21 to block the air outlet hole at the bottom end of the seal cover structure 2. The internal gas regulating air valve 23 is in the sealed space. As the downstream of the regulating air valve 23, the air pressure increases and passes through the regulating air valve 23 into the outside. After releasing the regulating air valve 23, since the internal air is emptied, the seal ball 21 leaves the air outlet hole, and the gas inside the storage tank 1 enters the inside of the seal cover structure 2. After repeating the above operations until most of the gas in the tank is exhausted, the internal and external pressures make the seal cover structure 2 hold against the storage tank 1 to achieve sealing. However, when the pipe needs to be opened, open the seal on the air release valve 11, and after balancing the air pressure, the seal cover structure 2 can be easily opened.

[0028] As Figure 3 , 4 , as shown in Figure 5, the regulating air valve 23 includes the following components: an air valve seat 24, which is placed inside the air valve pipe 12 and fixedly connected to one end of the main spring 22 away from the seal ball 21. A plurality of air valve seats 24 are connected to each other through uniformly distributed connecting rods 25, and the connecting rods 25 penetrate through the air valve plate 26. On the side of the air valve plate 26 away from the storage tank 1, there is a piston plate 27. The piston plate 27 is placed inside the air valve plate 26, its diameter is larger than that of the air valve seat 24, and it corresponds to the air valve pipe 12. Inside the air valve plate 26, there is a tension spring 28 fixedly connected, and the tension spring 28 is located below the piston plate 27. One end of the air valve pipe 12 away from the storage tank 1 is connected to a T-shaped pressing plate 15 through a pressing spring 14. The pressing plate 15 is placed inside the seal cover structure 2, and its periphery is surrounded by an arc-shaped ventilation hole 16 located inside the seal cover structure 2.

[0029] In this implementation scheme, it should be noted that there is a through hole with a diameter larger than that of the air valve plate 26 on the upper end of the air valve seat 24, which is only for illustration in the figure. When the pressing plate 15 compresses the pressing spring 14 to drive the air valve seat 24 to press down, a sealed space is formed inside the air valve pipe 12 due to the action of the seal ball 21 and the air valve plate 26. Thus, the internal pressure gradually increases as the space becomes smaller, pushing the air valve plate 26 up to the upper end of the air valve seat 24 and continuing to push open the piston plate 27, stretching the tension spring 28. The exhausted gas passes through the air valve pipe 12 into the ventilation hole 16 and is discharged. When the pressing plate 15 is released, the seal ball 21 leaves the inclined plane 13, and the gas inside the storage tank 1 fills the air valve pipe 12. The bottom end of the air valve seat 24 holds against the air valve plate 26 and drives it to rise to prevent the gas from leaking through the piston plate 27.

[0030] In use, the seal cover structure 2 is correctly installed above the storage tank 1, ensuring that the positions of the sealing ball 21, the air valve pipe 12, and the main spring 22 are matched. Press the regulating air valve 23. At this time, the main spring 22 will drive the sealing ball 21 to move downward to the bottom end of the seal cover structure 2, sealing the air outlet hole to ensure sealing. Continuously press the regulating air valve 23 to make the valve plate 26 move downward, compressing the internal space of the air valve, increasing the internal pressure. The gas is extruded through the regulating air valve 23, passes through the air valve pipe 12, and enters the arc-shaped ventilation holes 16 around the pressing plate 15, and is released into the external environment. Release the pressing plate 15, and the sealing ball 21 will leave the inclined surface 13 in the air valve pipe 12, enabling the gas inside the storage tank 1 to enter the air valve pipe 12. With the help of the valve plate 26, the valve seat 24 drives the piston plate 27 and the tension spring 28 to rise together, sealing the gas inlet to prevent external gas from entering the storage tank 1. Repeatedly press and release the regulating air valve 23 to ensure that most of the gas inside the storage tank 1 is discharged, and verify whether the seal cover structure 2 fits tightly against the storage tank 1 until it is in a sealed state. When it is necessary to open the radiation-proof tank, first open the seal on the air release valve 11 to balance the internal and external air pressures. After the air pressures are balanced, the seal cover structure 2 can be easily opened to take out or put in the required contents.
