Description

Technical Field

[0001] The utility model relates to the technical field of tungsten alloy protective cans, in particular to a tungsten alloy protective can. Background Art

[0002] Tungsten alloy is an alloy composed of tungsten as the base and other elements. Among metals, tungsten has the highest melting point, and has good high-temperature strength and creep resistance, as well as thermal conductivity, electrical conductivity and electron emission properties. Tungsten alloy products are the best material for shielding parts. They are easy to process and non-toxic, and are an environmentally friendly material. Compared with traditional shielding materials, tungsten alloy shielding parts have great value and are often used in the storage and transportation of radioactive drugs.

[0003] Authorization announcement number CN216671210U describes a tungsten alloy marking canister for radiopharmaceuticals, comprising a tungsten alloy canister and a housing. The canister comprises a canister body and a canister lid. The canister body is a thick-walled, open canister-shaped structure with external threads A at the upper opening and external threads B at the lower outer end. The canister lid is located on the upper portion of the canister body and has internal threads A corresponding to the external threads A on its inner side. The housing is used to house the tungsten alloy canister and is made of tungsten alloy shielding material. The housing comprises a shell and a shielding lid. The shell is a rectangular, enclosed structure with a marking surface on the front end and multiple mounting slots on the upper end. This utility model utilizes the cavities formed by the shielding lid to shield and protect multiple tungsten alloy canisters, further preventing radiation leakage and providing enhanced protection.

[0004] Although the above tungsten alloy tank solves certain problems, it still has the following disadvantages:

[0005] (1) The lid is connected to the tank body only by threaded connection. If the lid is hit during transportation, it may easily cause the lid to rotate, affecting the overall sealing of the protective tank.

[0006] (2) The lid and the tank body are connected by threaded connection. While the threads are used for connection, the threads must also ensure the sealing of the tank body, and high precision is required in production and processing. Utility Model Content

[0032] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figures 1 to 6 As shown, this embodiment proposes a tungsten alloy protective tank, including a tank body 1, a mounting ring block 2, an upper cover 3, a spring 4, a positioning mechanism 5, a sealing ring block 6, a cavity 7, a locking slot 8, a sealing block 9 and a locking buckle 10 connected to the lower side of the upper cover 3.

[0036] Among them, the tank body 1 is made of tungsten alloy, and medical radioactive materials are placed inside it for transportation. A sealing ring block 6 is fixedly connected to the upper end of the tank body 1. The sealing ring block 6 and the tank body 1 are integrated. An annular mounting ring block 2 is fixedly connected to the upper side of the tank body 1 by bolts. The mounting ring block 2 is also made of tungsten alloy. A cavity 7 is opened inside the mounting ring block 2. The mounting ring block 2 is sleeved on the outside of the sealing ring block 6. The outer upper end of the mounting ring block 2 is flush with the upper end of the sealing ring block 6. Four evenly distributed locking slots 8 are opened on the outer upper side of the mounting ring block 2. Each locking slot 8 is connected by a circular hole with a slightly larger radius and an arc-shaped groove.

[0037] When the upper cover 3 needs to be opened, the upper cover 3 is rotated in the opposite direction to allow the lock catch 10 to be rotated out of the arc-shaped groove in the lock catch slot 8.

[0038] In order to prevent the upper cover 3 from rotating due to collision during transportation and causing the upper cover 3 to fall off from the tank body 1, a connecting hole 11 is opened on one side of the upper end of the outer part of the upper cover 3, and a positioning screw 501 is connected to the internal thread of the connecting hole 11. After the positioning screw 501 is tightened downward, it can pass from the upper side of the upper cover 3 into the inside of the positioning hole 502 opened on the upper side of the outer part of the tank body 1 after rotation and locking, preventing the upper cover 3 and the tank body 1 from rotating relative to each other at will, and positioning the upper cover 3 and the tank body 1. Since the four locking buckles 10 are fixedly connected to the lower end of the upper cover 3, four positioning holes 502 are also correspondingly provided on the mounting ring block 2. In this way, no matter at which angle the upper cover 3 is covered on the upper side of the tank body 1, after locking, the positioning screw 501 can be controlled to move downward by turning the knob 14 to achieve positioning.

[0039] Example 2:

[0040] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0041] In order to make the upper cover 3 and the tank body 1 as airtight as possible after being tightened between the upper cover 3 and the tank body 1, a sealing block 9 used in conjunction with the sealing ring block 6 is fixedly connected to the lower end of the upper cover 3, and four spring pieces 4 are set on the upper side of the interior of the cavity 7. The four spring pieces 4 are at a certain distance from the upper side of the interior of the cavity 7. The upper side of one end is fixedly connected to the upper side of the cavity 7, and the other end is tilted upward, and each spring piece 4 is located directly below the lock buckle slot 8, and a lock buckle 1 is provided on the upper side of each spring piece 4. 0 uses a sliding slot 12, which has the same shape as the lock slot 8, but the end of the sliding slot 12 away from the upper side of the inner part of the connection cavity 7 is a semicircular shape, which facilitates the entry of the lock 10. After the lock 10 enters the interior of the cavity 7, the circular block at the lower end of the lock 10 passes through the semicircular part inside the sliding slot 12. As the upper cover 3 rotates, the spring piece 4 squeezes the upper cover 3 downward as a whole through the lock 10, so that the upper cover 3 can always be subjected to the external force of fitting downward on the tank body 1 to ensure sealing.

[0042] Example 3:

[0043] The solution in Example 2 is further introduced below in conjunction with a specific working method, as described below:

[0044] A connecting block 15 is fixedly connected to the upper side of the upper cover 3. A semicircular handle 13 is also provided on the upper side of the upper cover 3. The lower ends of the handle 13 are hinged to the two sides of the outside of the connecting block 15 respectively. The handle 13 facilitates the movement of the tungsten alloy protective tank and the rotation of the upper cover 3.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
