Description

Technical Field

[0001] The utility model relates to the technical field of crucible storage equipment, and more specifically, to a crucible rack that is convenient for taking and placing. Background Technique

[0002] A crucible is a cup-shaped vessel used in laboratories for high-temperature heating of solids. There are many types and specifications of crucibles, which are not restricted by production scale, batch size, and the variety of smelted substances during application. They can be arbitrarily selected, have strong applicability, and can ensure the purity of the smelted substances. When not in use, crucibles are usually placed in a rack for storage.

[0003] In the existing published technology, the application number is: CN202021097123.9, a crucible rack for a muffle furnace that is convenient for taking and placing, which discloses support columns, brackets, and support frames. The brackets and support frames are respectively fixedly connected to the support columns, and the brackets are located above the support frames; a clamping part is provided on the support columns; several placement rings for placing crucibles are provided on the brackets. After the crucible is placed in the placement ring, a part of it protrudes above the placement ring, and the bottom of the crucible presses on the support frame, and the crucible is supported by the support frame.

[0004] The existing racks still have certain disadvantages when in use: Most traditional crucible racks are composed of multiple groups of metal strips welded to each other. The overall structure is non-adjustable and non-detachable. It can be used for placing different numbers of crucibles. However, when the number of placed crucibles is small, it is easy to cause waste of space, resulting in a large floor area, which is inconvenient for personnel to place other objects in a limited space, making the overall use flexibility not very good. Moreover, it is not very convenient to take out the crucibles subsequently. And when the crucible is placed, there is a certain height difference between it and the bottom surface of the supporting structure. Direct placement is likely to cause damage to the crucible due to impact, making the protection effect during placement not very ideal and not conducive to better placement and use.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0033] In one embodiment, a limiting groove 11 is provided through the middle position of the surface of the limiting plate 9, and a plurality of fixed plates 4 are installed around the surface of the limiting groove 11 and the surface of the accommodating groove 2. A movable plate 5 is slidably connected to the inner position of the fixed plate 4, and a clamping plate 6 is fixedly installed at one end of the movable plate 5. The other end of the movable plate 5 is located inside the fixed plate 4 and is connected to a second spring 23. The second spring 23 is provided to clamp the crucible between the clamping plates 6 by its own compression and deformation reset, thereby expanding the application range of the device and facilitating better use.

[0034] In one embodiment, a limiting groove 11 is provided through the middle position of the surface of the limiting plate 9, and a plurality of fixed plates 4 are installed around the surface of the limiting groove 11 and the surface of the accommodating groove 2. A movable plate 5 is slidably connected to the inner position of the fixed plate 4, and a clamping plate 6 is fixedly installed at one end of the movable plate 5. The other end of the movable plate 5 is located inside the fixed plate 4 and is connected to a second spring 23.

[0035] In one embodiment, a limiting groove 11 is provided through the middle position of the surface of the limiting plate 9, and a plurality of fixed plates 4 are installed around the surface of the limiting groove 11 and the surface of the accommodating groove 2. A movable plate 5 is slidably connected to the inner position of the fixed plate 4, and a clamping plate 6 is fixedly installed at one end of the movable plate 5.

[0036] In one embodiment, a plurality of groups of legs 22 are symmetrically welded around the bottom of the support plate 1 , and the entire device can be fixed by the legs 22 , so as to enhance the overall stability in use.

[0037] In one embodiment, the pull plate 8 is a T-shaped structure. The T-shaped structure is provided to facilitate personnel to move the pull plate 8 through the long strip on the top, thereby facilitating the assembly or separation of the structure and ensuring the convenience of use of the structure.

[0038] In one embodiment, a slot is provided at the top of the adjustment slot 7 for movement of the pull plate 8, and the slot size is larger than the structural size of the bottom surface of the pull plate 8 and smaller than the size of the first spring 10. The slot structure on the surface of the adjustment slot 7 is provided to ensure smooth movement of the pull plate 8 while preventing the first spring 10 from detaching from the inside of the adjustment slot 7 when squeezed, thereby ensuring normal use of the structure.

[0039] Working principle: During actual use, the structures for placing crucibles all adopt a monomeric independent design, which can select different numbers of structures according to the different numbers of crucibles to be placed subsequently. This can improve the overall flexibility of use and avoid waste of space caused by a small number of crucibles carried due to the fixed structure, enhancing the overall use effect. And when multiple groups of structures need to be connected, the docking head 18 on its surface can be inserted into the positioning groove 16 on the other side. At this time, the insertion rod 15 in the positioning groove 16 is inserted into the opening in the docking head 18 to achieve the splicing operation of the structures, so as to facilitate subsequent personnel to perform synchronous movement operations on the structures. When the structures need to be disassembled, only by dragging the pull plate 8 can the first spring 10 be compressed to make the insertion rod 15 disengage from the docking head 18. At this time, the structures can be easily dispersed, facilitating subsequent use. After all adjustments are completed, personnel can first pull the pull rod 13 to move the top block 17 upward as a whole. Then, personnel can place the crucible into the limiting groove 11. At this time, the bottom of the crucible will abut against the surface of the top block 17. Then, slowly move the pull rod 13, which can synchronously move the crucible and the top block 17 downward, so that the crucible will not be damaged by impact due to sudden falling during movement, improving the placement protection effect of the crucible. And when the crucible moves to the bottom, the airbag can buffer the crucible, reducing the impact force during contact, thereby improving the overall protection effect. Moreover, after the crucible is placed in the limiting groove 11, the moving plate 5 can be squeezed, causing the second spring 23 connected to it to be compressed accordingly. Subsequently, through the deformation and reset of the second spring 23, the clamping plate 6 can be abutted against the surface of the crucible, enabling the limiting groove 11 to clamp and fix crucibles of different sizes, improving the versatility of the structure and thus enhancing the overall use effect. When the crucible is taken out subsequently, only by pulling the pull rod 13 can the crucible be lifted as a whole by the upward movement of the top block 17, facilitating personnel to take it out, improving the overall taking efficiency and being convenient for better use. The overall device has the advantages of flexible structure, convenient loading and unloading, and placement protection.
