Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a graphite crucible clamp. Background Technology

[0002] During the use of graphite crucibles, they often need to be handled and transferred. However, because graphite crucibles are brittle and have a smooth surface, handling them directly by hand can easily burn operators and may also cause the crucible to slip and break. Therefore, graphite crucible clamps have emerged. Most existing graphite crucible clamps are relatively simple in structure and usually only have basic clamping functions.

[0003] However, in actual use, the parts of the clamp that contact the crucible are prone to wear or damage due to frequent friction, collisions, and the effects of high-temperature environments. Once these parts are damaged, the entire clamp often needs to be scrapped, which not only increases the cost of use but also wastes resources. Moreover, because the crucible is used in a high-temperature environment, the parts of the clamp that contact the crucible are subject to thermal expansion and contraction. If the installation structure of the contact parts is not reasonable, it is easy for them to loosen, affecting the stability of the clamping.

[0004] Therefore, this application provides a graphite crucible fixture to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A graphite crucible clamp includes two staggered handles, one end of each handle is fixed with a jaw to form a clamping mechanism, the two jaws are arc-shaped concave structures adapted to the outer wall of the crucible, and the inner wall of the jaws is uniformly provided with multiple base frames, and a contact block is fitted on the side of the base frame away from the jaws.

[0007] One side of the base frame is provided with a mounting groove for the contact block to be inserted, and a stud is fixed on the other side of the base frame. The stud extends out of the clamp and is fitted with a fastening nut.

[0008] Optionally, a protective sleeve is provided at the end of the handle away from the gripper.

[0009] Optionally, a groove is provided in the middle of the inner wall of the mounting groove, and a heat-resistant rubber pad is embedded and fixed in the groove, the heat-resistant rubber pad abutting against the outer surface of the contact block.

[0010] Optionally, the fastening nut is threaded onto the stud and abuts against the outer edge of the clamp to fix the base frame.

[0011] Optionally, at least two sets of base frames and contact blocks are provided on the inner side of the gripper.

[0012] Optionally, a limiting piece is hinged to one end of one of the handles away from the gripper, and the limiting piece engages with the other handle to form a limiting position.

[0013] Optionally, the limiting piece has an L-shaped structure, and the inner wall of the end of the limiting piece is provided with a buffer pad for contacting the handle.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, thanks to the cooperation of the handle, gripper, base frame and contact block, when using the gripper to hold the graphite crucible, the contact block on the inner side of the base frame can be used to abut against the inner wall of the graphite crucible, which is convenient to replace it separately after damage, without scrapping the entire fixture.

[0016] In the above scheme, thanks to the heat-resistant rubber pads installed inside the base frame, the installation effect of the contact block inside the base frame can be guaranteed, and the contact block can be prevented from loosening due to thermal expansion and contraction, which would affect the clamping stability of the graphite crucible.

[0017] In the above solution, thanks to the setting of the limiting plate, the gripper can limit the two handles after clamping the graphite crucible, thus avoiding the problem of unstable clamping caused by operational errors.

[0018] In summary, this device reduces operating costs through a detachable contact block design, ensures clamping stability through heat-resistant rubber pads, and enhances clamping reliability through limiting plates. Overall, it offers the advantages of convenient use, low cost, and stable clamping, resulting in excellent performance. Attached Figure Description

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a graphite crucible clamp, which mainly consists of two staggered handles 1. A gripper 2 is fixed to one end of each handle 1, thus forming a clamping mechanism. The two grippers 2 adopt an arc-shaped concave structure design adapted to the outer wall of the crucible. This design allows for better contact with the outer wall of the crucible, increasing the contact area between the clamp and the crucible, and improving the stability and accuracy of the clamping. In practical applications, when the grippers 2 clamp the crucible, the arc-shaped concave structure can evenly distribute the clamping force, preventing excessive localized stress on the crucible and potential damage.

[0033] Multiple base frames 3 are evenly arranged on the inner wall of the gripper 2, and a contact block 4 is fitted onto the side of each base frame 3 away from the gripper 2. The contact block 4 directly contacts the outer wall of the graphite crucible and plays a crucial role in the clamping process. The contact block 4 can be made of high-temperature resistant and wear-resistant materials, such as ceramics or special alloys, to ensure stable operation for a long time in high-temperature environments and to prevent wear. A mounting groove 301 is provided on one side of the base frame 3 for the contact block 4 to be embedded. The size and shape of the mounting groove 301 match the contact block 4 to ensure that the contact block 4 can be accurately embedded. A groove is provided in the middle of the inner wall of the mounting groove 301, and a heat-resistant rubber pad 303 is fitted and fixed in the groove, abutting against the outer surface of the contact block 4. The heat-resistant rubber pad 303 can be made of high-temperature resistant materials such as silicone rubber, which has good elasticity and heat resistance. The heat-resistant rubber pad 303 effectively ensures the installation of the contact block 4 within the base frame 3. Since the graphite crucible is exposed to high temperatures during use, the contact block 4 is subject to thermal expansion and contraction. The heat-resistant rubber pad 303 buffers this effect, preventing the contact block 4 from loosening and ensuring the clamping stability of the graphite crucible. When the contact block 4 expands due to heat, the heat-resistant rubber pad 303 can be compressed, providing expansion space for the contact block 4; when the contact block 4 cools and contracts, the heat-resistant rubber pad 303 can return to its original shape, continuing to tightly adhere to the contact block 4 and preventing it from shaking.

[0034] A stud 302 is fixed to the other side of the base frame 3, extending beyond the gripper 2 and fitted with a fastening nut 5. The fastening nut 5 is threaded onto the stud 302 and abuts against the outer edge of the gripper 2, thus securing the base frame 3. When the contact block 4 needs to be replaced due to wear or other reasons, simply loosen the fastening nut 5, remove the base frame 3 from the gripper 2, and replace the contact block 4 with a new one. This eliminates the need to scrap the entire fixture, significantly reducing operating costs. Furthermore, this detachable design facilitates maintenance and extends the fixture's lifespan. At least two sets of base frames 3 and contact blocks 4 are provided inside the gripper 2, increasing the contact area between the fixture and the crucible and improving clamping stability. In practical applications, the number of base frames 3 and contact blocks 4 can be appropriately increased based on the size and weight of the crucible to achieve better clamping performance.

[0035] A protective sleeve 101 is fitted onto the end of the handle 1 furthest from the gripper 2. The protective sleeve 101 can be made of materials such as rubber. Rubber has good heat insulation and anti-slip properties, which can protect the operator's hands from burns and also make it easier for the operator to grip the handle 1. The surface of the protective sleeve 101 can be designed with anti-slip texture to further increase the stability of the grip and prevent the handle 1 from slipping from the hand during operation.

[0036] In another embodiment of this utility model, such as Figure 4 As shown, the difference from the above embodiment is that:

[0037] A limiting plate 6, L-shaped in structure, is hinged to the end of one handle 1 furthest from the gripper 2. The inner wall of the limiting plate 6 has a buffer pad 7 for contacting the handle 1; the buffer pad 7 can be made of soft materials such as sponge or rubber. After the gripper 2 holds the graphite crucible, the limiting plate 6 is rotated to engage with the other handle 1, thus creating a limiting position and preventing instability caused by operational errors. The buffer pad 7 reduces collisions and wear between the limiting plate 6 and the handle 1, extending the clamp's lifespan. Simultaneously, the buffer pad 7 increases the friction between the limiting plate 6 and the handle 1, making the limiting position more secure. In actual operation, when clamping the crucible, the operator holds both handles 1, aligns the gripper 2 with the graphite crucible, and tightens the handles 1 to clamp the crucible. At this point, the contact block 4 is in close contact with the outer wall of the crucible, completing the clamping operation. Then, the limiting plate 6 is rotated to engage with the other handle 1, ensuring clamping stability. When it is necessary to release the crucible, first rotate the limiting piece 6 back to its original position, and then release the handle 1.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
