Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot chamber lead canister cap removal technology, and in particular to a cap removal structure for doubling the stroke of a nuclear medicine hot chamber lead canister. Background Technology
[0002] In the field of nuclear medicine, hot-cell lead containers play a crucial role in storing various radioactive materials and ensuring the safety of the operating environment and personnel. With the continuous development of the nuclear medicine industry, higher demands are placed on the convenience, efficiency, and safety of hot-cell lead container operation. In the daily use of lead containers, the opening and closing of the lid is a frequent and critical operation. Most existing hot-cell lead container lid-opening structures are designed based on conventional mechanical transmission principles, with relatively fixed and short opening strokes. Commonly, simple linkage mechanisms or single-stage telescopic devices are used to achieve the lid-opening action. This is inconvenient when a larger opening is needed for easier handling of internal radioactive samples, equipment maintenance, and other operations. To address these issues, a lid-opening structure with doubled stroke for nuclear medicine hot-cell lead containers is proposed. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a doubling-stroke capping structure for lead containers in nuclear medicine hot chambers. The structure includes a base plate, a blocking block below the base plate, a pulley at the upper end of the blocking block, a contact block above the blocking block, a connecting rod fixedly mounted on the upper surface of the contact block, a lifting block fixedly mounted above the connecting rod, a folding rod mounted on the lifting block, a guide rod sleeved on the lifting block, an operating plate at the upper end of the guide rod, and a slide rail fixedly mounted on the base plate, with the slide rail located on the slide rail.
[0004] Furthermore, the blocking block is fixedly installed on the external operating table. The cross-section of the contact block is trapezoidal with a left-longer and right-shorter shape, with the upper end horizontal and fixedly connected to the connecting rod. It also has an arc-shaped groove on the left side. The slide rail is double-rail shaped, and the base plate has an opening between the two tracks of the slide rail. The slide block is located on the two tracks. There are two sets of folding rods, which are located on both sides of the lifting block. The upper end of each set of folding rods is connected to the operating plate through a pivot, the lower end is connected to the slide block through a pivot, and the middle part is connected to the lifting block through a pivot, forming a figure-eight shape.
[0005] Furthermore, a limit plate is provided at the right end of the slide rail, and a can placement plate is provided on the right side of the limit plate. The can placement plate is fixedly mounted on the base plate, and a can body is placed on the can placement plate. A cover is provided on the operation plate.
[0006] Furthermore, an adjusting bolt is provided at the upper end of the slide block, and an adjusting bolt is provided on the right side of the slide block.
[0007] The beneficial effects of this utility model are:
[0008] This invention involves placing an uncapped lead can on a can-placement tray and pushing a base plate to the right. The base plate moves the entire structure to the right. During this movement, a contact block encounters a blocking block fixed to an external operating platform. The conical surface of the contact block contacts the pulley of the blocking block, causing the contact block to move upwards. The clamping block then moves the connecting rod and lifting block upwards. The lifting block, through two sets of figure-eight folding rods, doubles the distance the operating plate rises. During this process, the operating plate lifts the cap off the can. When the pulley of the blocking block contacts the groove of the contact block, the contact block is restrained by the blocking block and remains stationary. The base plate continues to move to the right. At this time, the contact block, connecting rod, lifting block, folding rod, operating plate, and slide remain in place. The base plate drives the slide rail and the can placement tray to continue moving. The can placement tray causes the can body to separate from the cover, thus removing the cover. Adjusting the adjusting bolt at the top of the slide can adjust the lifting height of the lifting block, thereby adjusting the height of the cover. Adjusting the distance between the adjusting bolt on the right side of the slide and the limiting plate can adjust the distance between the cover and the can. When it is necessary to close the cover, the base plate is moved in the opposite direction, and the above process is reversed to realize the closing action. This increases the height when the cover separates, making it easier to handle internal radioactive samples, equipment maintenance, and other operations, thus improving safety.

[0017] This utility model provides a doubling capping structure for lead containers in nuclear medicine hot chambers, characterized by including a base plate 1, a blocking block 2 disposed below the base plate 1, a pulley at the upper end of the blocking block 2, a contact block 3 disposed above the blocking block 2, a connecting rod 4 fixedly disposed on the upper surface of the contact block 3, a lifting block 5 fixedly disposed above the connecting rod 4, a folding rod 6 disposed on the lifting block 5, a guide rod 7 sleeved on the lifting block 5, an operating plate 8 disposed at the upper end of the guide rod 7, and a slide block 10 fixedly disposed at the lower end, a slide rail 9 fixedly disposed on the base plate 1, and the slide block 10 located on the slide rail 9;
[0018] Furthermore, the blocking block 2 is fixedly installed on the external operating table. The cross-section of the contact block 3 is a trapezoid with a longer left side and a shorter right side. The upper end is horizontal and is fixedly connected to the connecting rod 4. There is an arc-shaped groove on the left side. The slide rail 9 is double-rail. The base plate 1 has an opening between the two tracks of the slide rail 9. The slide seat 10 is located on the two tracks. There are two sets of folding rods 6, which are located on both sides of the lifting block 5. The upper end of each set of folding rods 6 is connected to the operating plate 8 through a rotating shaft, the lower end is connected to the slide seat 10 through a rotating shaft, and the middle part is connected to the lifting block 5 through a rotating shaft, forming an 8-shape.
[0019] Furthermore, a limit plate 11 is provided at the right end of the slide rail 9, and a can placement plate 14 is provided on the right side of the limit plate 11. The can placement plate 14 is fixedly mounted on the base plate 1, and a can body 13 is provided on the can placement plate 14. A cover 12 is provided on the operation plate 8.
[0020] Furthermore, an adjusting bolt 15 is provided at the upper end of the slide 10, and an adjusting bolt 15 is provided on the right side of the slide 10.
[0021] Example 2
[0022] In use, place the uncapped lead can on the can placement tray 14, push the base plate 1 to the right, and the base plate 1 will move the entire structure to the right. During this pushing, the contact block 3 will encounter the blocking block 2 fixed to the external operating table. The conical surface of the contact block 3 will contact the pulley of the blocking block 2, causing the contact block 3 to move upward. The clamping block will then move the connecting rod 4 and the lifting block 5 upward. The lifting block 5 will double the distance the operating plate 8 rises through two sets of figure-eight folding rods 6. During this process, the operating plate 8 will lift the cap 12 from the can body 13. When the pulley of the blocking block 2 contacts the groove of the contact block 3, the contact block 3 will be restricted by the blocking block 2, thus maintaining its position. While holding the position still, the base plate 1 continues to move to the right. At this time, the contact block 3, connecting rod 4, lifting block 5, folding rod 6, operating plate 8, and slide 10 remain in the same position. The base plate 1 drives the slide rail 9 and can placement tray 14 to continue moving. The can placement tray 14 drives the can body 13 to separate from the lid 12, thus removing the lid. Adjusting the adjusting bolt 15 at the upper end of the slide 10 can adjust the lifting height of the lifting block 5, thereby adjusting the height of the lid 12. Adjusting the distance between the adjusting bolt 15 on the right side of the slide 10 and the limiting plate 11 can adjust the distance between the lid 12 and the can 13. When it is necessary to close the lid, the base plate 1 is moved in the opposite direction, and the above process is reversed to realize the closing action.
