Description

Technical Field

[0001] This utility model belongs to the field of crucible technology, specifically a crucible that is easy to handle. Background Technology

[0002] Crucibles are indispensable high-temperature reaction vessels in fields such as chemistry and materials science. They are usually made of high-temperature resistant materials (such as ceramics, graphite, metals or corundum) and have excellent thermal stability and chemical inertness.

[0003] The currently used crucibles have a cylindrical structure and are not equipped with handles, relying entirely on external tools, such as crucible tongs, for clamping. However, due to the lack of dedicated grip protrusions, grooves, or precise positioning structures, operators need to continuously apply significant clamping force to maintain stability during manual handling and transfer. Prolonged operation can easily lead to muscle fatigue, significantly increasing the risk of operational errors. In addition, relying solely on crucible tongs is not only laborious but also prone to causing the crucible to wobble, affecting experimental accuracy. Furthermore, the excessively smooth outer surface of the crucible limits the clamping contact area, further exacerbating the slippage of tools such as crucible tongs, causing great inconvenience for operators to handle crucibles safely and efficiently. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a crucible that is easy to handle, thus offering the advantage of convenient handling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crucible that is easy to handle, comprising a crucible body, a base plate fixedly installed on the outer surface of the crucible body, a through hole opened in the interior of the base plate, a top plate fixedly installed on the outer surface of the crucible body above the base plate, an L-shaped block movably fitted inside the through hole, a heat insulation block fixedly connected to the right end of the L-shaped block, a handle fixedly connected to the right end of the heat insulation block, a movable locking plate movably fitted inside the handle, the left end of the movable locking plate penetrating through the heat insulation block and extending to the outside of the heat insulation block and movably fitted with the inner wall of the heat insulation block, the bottom of the movable locking plate movably connected to the top of the L-shaped block, the outer surface of the movable locking plate movably connected to the bottom of the top plate, a circular plate fixedly connected to the right end of the movable locking plate, a first spring fixedly connected to the right end of the circular plate, the right end of the first spring fixedly connected to the inner wall of the handle, and a connecting rod fixedly connected to the top of the movable locking plate.

[0006] As a preferred embodiment of this utility model, a push plate is fixedly connected to the top of the connecting rod, the bottom of the push plate is movably connected to the outer surface of the handle, and the top of the push plate is provided with anti-slip texture.

[0007] As a preferred embodiment of this invention, a side plate is fixedly connected between the bottom plate and the top plate, and the outer surface of the side plate is fixedly connected to the outer surface of the crucible body.

[0008] As a preferred embodiment of this invention, a flow guide groove is fixedly fitted inside the top left side of the crucible body, and an anti-slip sleeve is fixedly fitted on the right side of the outer surface of the handle.

[0009] In a preferred embodiment of this invention, a card block is movably sleeved inside the movable card plate, and a movable plate is fixedly connected to the bottom of the card block. The outer surface of the movable plate is movably sleeved with the inner surface of the movable card plate.

[0010] As a preferred embodiment of this utility model, a second spring is fixedly connected to the bottom of the movable plate, and the bottom end of the second spring is fixedly connected to the bottom of the inner surface of the movable plate.

[0011] As a preferred embodiment of this utility model, an inclined block is fixedly installed inside the grip between the locking block and the connecting rod. The outer surface of the inclined block is movably connected to the outer surface of the locking block and the connecting rod, respectively. A fixing block is fixedly installed on the left side of the inclined block. A pressing block is movably sleeved on the outer surface of the fixing block. The bottom of the pressing block is movably connected to the top of the locking block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a handle and a movable clamping plate, allows operators to pick up the crucible body and perform operations such as flipping and tilting simply by holding the handle when handling the crucible body. This avoids the need to maintain a clamping action for a long time when using crucible tongs, making it more convenient for operators. When it is necessary to heat the crucible body, simply move the movable clamping plate to the right to disconnect the connection between the crucible body and the handle, preventing heat from being transferred to the handle during heating.

[0014] 2. This utility model, by setting a locking block, an inclined block, and a pressing block, ensures that when the crucible body is connected to the handle, the locking block is located to the left of the inclined block, preventing the locking block from moving left or right. This, in turn, fixes the moving locking plate, allowing it to be stably inserted between the L-shaped block and the top plate. This prevents the L-shaped block from moving upward and dislodging from the through hole, thus ensuring a stable connection between the crucible body and the handle. This improves safety during use. Furthermore, when it is necessary to disassemble the crucible body, simply pressing the pressing block releases the connection between the crucible body and the handle. The operation is simple and convenient for operators. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 7As shown, this utility model provides a crucible that is easy to handle, including a crucible body 1. A base plate 2 is fixedly installed on the outer surface of the crucible body 1. A through hole 3 is opened inside the base plate 2. A top plate 4 located above the base plate 2 is fixedly installed on the outer surface of the crucible body 1. An L-shaped block 5 is movably sleeved inside the through hole 3. A heat insulation block 6 is fixedly connected to the right end of the L-shaped block 5. A handle 7 is fixedly connected to the right end of the heat insulation block 6. A movable locking plate 8 is movably sleeved inside the handle 7. The left end of the movable locking plate 8 passes through the heat insulation block 6 and extends to the outside of the heat insulation block 6 and is movably sleeved with the inner wall of the heat insulation block 6. The bottom of the movable locking plate 8 is movably connected to the top of the L-shaped block 5. The outer surface of the movable locking plate 8 is movably connected to the bottom of the top plate 4. A circular plate 9 is fixedly connected to the right end of the movable locking plate 8. A first spring 10 is fixedly connected to the right end of the circular plate 9. The right end of the first spring 10 is fixedly connected to the inner wall of the handle 7. A connecting rod 11 is fixedly connected to the top of the movable locking plate 8.

[0025] The operator can pick up the crucible body 1 by holding the handle 7. When the crucible body 1 needs to be heated, the first spring 10 is in a stretched state, which can drive the circular plate 9 to move to the right under the elastic recovery action, so that the left end of the moving plate 8 moves to the right and enters the interior of the heat insulation block 6. At this time, the operator moves the handle 7 upward, so that the L-shaped block 5 moves upward and disengages from the interior of the through hole 3, so that the handle 7 can be moved to the right and the handle 7 is separated from the crucible body 1.

[0026] The top of the connecting rod 11 is fixedly connected to the push plate 12, the bottom of the push plate 12 is movably connected to the outer surface of the handle 7, and the top of the push plate 12 is provided with anti-slip texture 13.

[0027] By setting anti-slip texture 13, the anti-slip texture 13 can play an anti-slip role. The operator can push the push plate 12 to the left, thereby driving the connecting rod 11 to move to the left, and thus causing the moving plate 8 to move to the left.

[0028] A side plate 14 is fixedly connected between the bottom plate 2 and the top plate 4, and the outer surface of the side plate 14 is fixedly connected to the outer surface of the crucible body 1.

[0029] The inner side of the side plate 14 is inclined, which can serve as a guide, so that the L-shaped block 5 can be inserted more smoothly between the bottom plate 2 and the top plate 4.

[0030] The crucible body 1 has a flow guide groove 15 fixedly fitted inside the top left side, and the handle 7 has an anti-slip sleeve 16 fixedly fitted on the right side of the outer surface.

[0031] By setting the anti-slip sleeve 16, the operator can prevent slipping when holding the handle 7, making it more stable to pick up the crucible body 1.

[0032] The movable card plate 8 has a card block 17 movably sleeved inside, and a movable plate 18 is fixedly connected to the bottom of the card block 17. The outer surface of the movable plate 18 is movably sleeved with the inner surface of the movable card plate 8.

[0033] When the position of the locking block 17 is fixed and cannot move left or right, the moving locking plate 8 will be fixed, so that the handle 7 and the crucible body 1 can be stably connected together, avoiding accidents when picking up the crucible body 1.

[0034] The bottom of the movable plate 18 is fixedly connected to a second spring 19, and the bottom end of the second spring 19 is fixedly connected to the bottom of the inner surface of the movable plate 8.

[0035] When the locking block 17 moves downward, it will cause the movable plate 18 to move downward, thereby compressing the second spring 19. After being compressed, the second spring 19 can push the movable plate 18 and the locking block 17 upward to reset under the elastic recovery action.

[0036] The grip 7 has an inclined block 20 fixedly installed inside between the locking block 17 and the connecting rod 11. The outer surface of the inclined block 20 is movably connected to the outer surface of the locking block 17 and the connecting rod 11 respectively. A fixing block 21 is fixedly installed on the left side of the inclined block 20. A pressing block 22 is movably sleeved on the outer surface of the fixing block 21. The bottom of the pressing block 22 is movably connected to the top of the locking block 17.

[0037] The operator presses down the pressing block 22, causing the pressing block 22 to push the locking block 17 downward, causing the locking block 17 to disengage from the inclined block 20. At this time, the first spring 10 will pull the moving locking plate 8 to the left under the elastic recovery action.

[0038] Working principle and usage process of this utility model:

[0039] The operator can hold the handle 7 to pick up and flip the crucible body 1. When heating the crucible, the handle 7 needs to be removed. At this time, by pressing down the pressing block 22, the pressing block 22 pushes the locking block 17 downward, causing the locking block 17 to disengage from the inclined block 20, thereby releasing the fixing effect on the moving locking plate 8. At this time, the first spring 10 will pull the moving locking plate 8 to the right under the elastic recovery action, so that the left end of the moving locking plate 8 enters the interior of the heat insulation block 6. Then the operator moves the handle 7 upward, so that the L-shaped block 5 disengages from the interior of the through hole 3, and the handle 7 can be removed to heat the crucible body 1.

[0040] When it is necessary to connect the handle 7 to the crucible body 1, the L-shaped block 5 is inserted between the bottom plate 2 and the top plate 4. Then, the handle 7 is moved downward so that the bottom of the L-shaped block 5 is inserted into the through hole 3. Then, by pushing the push plate 12 to the left, the connecting rod 11 drives the moving plate 8 to move to the left, so that the left end of the moving plate 8 is inserted between the L-shaped block 5 and the top plate 4, thereby restricting the L-shaped block 5 and preventing it from moving upward. This ensures that the handle 7 is stably connected to the crucible body 1. When the moving plate 8 moves to the left, the inclined surface at the top of the locking block 17 will contact the bottom of the inclined block 20, causing the locking block 17 to be squeezed and pushed downward, thus moving the locking block 17 to the left side of the inclined block 20. At this time, the second spring 19 will push the locking block 17 upward to reset under the elastic recovery action, which can fix the moving plate 8.
