Description

Technical Field

[0001] This utility model belongs to the field of crucible support frame technology, specifically relating to a support frame suitable for pressure-resistant and fold-resistant graphite crucibles. Background Technology

[0002] Graphite crucibles are widely used in the field of non-ferrous metal smelting. The main components of graphite crucibles are natural flake graphite and binders. They have the advantages of fast heat conduction, high temperature resistance, good thermal stability, and non-reaction with the molten material. They are used as melting and casting vessels for non-ferrous metals. Graphite crucibles require a special graphite crucible support frame to fix them in place during use.

[0003] According to the published patent CN218410662U, a crucible handling device and muffle furnace equipment are disclosed, including a crucible support and fixing holes. The crucible support has multiple fixing holes, each for placing a crucible. The crucible support supports and fixes the crucible. A handling fork engages with the crucible support, allowing the crucible support to be moved into or out of the furnace chamber. The crucible handling device of this application, through the engagement of the crucible support and the handling fork, can move multiple crucibles in or out at once, improving efficiency. Furthermore, the crucibles placed within the fixing holes are stable and reliable, and are not easily tipped over.

[0004] However, there are still some shortcomings. For example, most of the existing crucibles are integral, which is inconvenient for operators to store. This results in the crucible support frame taking up a large area when not in use, and the fixing holes inside the support frame are of a single size, making it inconvenient to fix crucibles of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a support frame suitable for pressure-resistant and flexurally resistant graphite crucibles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support frame suitable for pressure-resistant and fold-resistant graphite crucibles, comprising a support frame body, with extension mechanisms provided on both sides of the support frame body, a first fixing hole opened inside the support frame body, the extension mechanism including extension plates hinged to both sides of the support frame body, the extension plates having a storage groove, a shaft hole and a second fixing hole opened inside, the storage groove and the shaft hole being integrally formed, the second fixing hole being located between the two storage grooves, a movable shaft being rotatably connected inside the shaft hole, a second support leg being fixedly connected between the two movable shafts, a first magnetic plate being fixedly connected to the inner top of the storage groove, and a second magnetic plate being embedded in the inner bottom of the support frame body.

[0007] As a further improvement of this utility model, the second support leg has two states: one is a vertical state and the other is a horizontal state.

[0008] As a further embodiment of this utility model: both the first fixing hole and the second fixing hole are circular in shape, and the diameter of the first fixing hole is smaller than the diameter of the second fixing hole.

[0009] As a further embodiment of this utility model: the second support leg is rectangular in shape, and when the second support leg is in a horizontal state, it is stored inside the storage groove. The second support leg is made of iron material.

[0010] As a further improvement of this utility model: the bottom of the support frame body is fixedly connected with a first support leg, and the number of the first support legs is four.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This support frame, suitable for pressure-resistant and flexurally resistant graphite crucibles, features an extension mechanism that allows for lengthening of the main body, facilitating the placement of multiple graphite crucibles for operation. Different sizes of crucibles can be secured using varying dimensions of the first and second fixing holes, enhancing the overall versatility of the support frame. The extension plate can be folded away, reducing the overall footprint of the support frame and allowing for easy storage and transportation. Both the main body and the extension plate are constructed from manganese steel, ensuring high strength and excellent pressure and flexural resistance. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 1-4 This utility model provides a support frame suitable for pressure-resistant and fold-resistant graphite crucibles, including a support frame body 1, an extension mechanism 2 on both sides of the support frame body 1, a first fixing hole 4 inside the support frame body 1, and a first support leg 3 fixedly connected to the bottom of the support frame body 1, the number of the first support leg 3 being four.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the extension mechanism 2 includes extension plates 5 hinged to both sides of the support frame body 1. The extension plates 5 have storage slots 6, shaft holes 7, and second fixing holes 12 inside. The storage slots 6 and shaft holes 7 are integrally formed. The second fixing holes 12 are located between the two storage slots 6. A movable shaft 8 is rotatably connected inside the shaft hole 7. A second support leg 9 is fixedly connected between the two movable shafts 8. A first magnetic plate 10 is fixedly connected to the inner top of the storage slots 6. A second magnetic plate 11 is embedded in the inner bottom of the support frame body 1. The second support leg 9 has two states: one is a vertical state and the other is a horizontal state. The first fixing hole 4 and the second fixing hole 12 are both circular in shape. The diameter of the first fixing hole 4 is smaller than the diameter of the second fixing hole 12. The second support leg 9 is rectangular in shape. When the second support leg 9 is in the horizontal state, it is stored inside the storage slots 6. The second support leg 9 is made of iron.

[0022] Working principle and usage process of this utility model:

[0023] In use, the extension plates 5 hinged on both sides of the support frame body 1 can be unfolded and laid flat, so that the extension plates 5 and the support frame body 1 are at the same horizontal height, thus extending the length of the support frame body 1. The extension plates 5 have a second fixing hole 12 inside, which is larger in diameter than the first fixing hole 4 inside the support frame body 1, allowing for the placement of larger crucibles. When used in conjunction with the first fixing hole 4, crucibles of different sizes can be fixed, effectively improving the applicability of the crucibles. After the extension plates 5 are unfolded horizontally, the second support leg 9 can be flipped out from inside the storage slot 6, so that the second support leg 9 is in a position of... The vertical angle supports the extension plate 5, improving its stability. When storing it later, the second support leg 9 is flipped inside the storage slot 6, making it horizontal. When the second support leg 9 is horizontal, one side of it is magnetically connected to the first magnetic plate 10, fixing the folded second support leg 9. After the second support leg 9 is folded, the extension plate 5 can be flipped. When the bottom of the extension plate 5 is attached to the bottom of the support frame body 1, the other side of the second support leg 9 is magnetically connected to the second magnetic plate 11, fixing the folded extension plate 5.

[0024] Although 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 alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
