Description

Technical Field

[0001] The utility model belongs to the field of saggers, and in particular relates to a sagger. Background Art

[0002] The current graphite saggers have the following disadvantages: 1. There are often problems of material leakage, cracking and fracture at the joints. The processing is difficult, the splicing process is complicated, and the cost reduction is relatively limited, which brings a lot of inconvenience to practical applications; 2. The combined structure of the graphite sagger is relatively complicated, and the shell will be broken during transportation or placement. The outer surface of the graphite sagger lacks a fastening structure, resulting in its poor stability.

[0003] A Chinese utility model patent discloses a combined graphite sagger (publication number: CN202220426658.9), which includes a bottom plate, a plurality of side plates, a plurality of graphite square columns and nails. The plurality of side plates are vertically arranged on the bottom plate along the four sides of the bottom plate and enclosed with the bottom plate to form a box structure with a cavity. The joints of any two adjacent side plates are clamped by a male and female port. The plurality of graphite square columns are respectively arranged along the joints between the side plate and the bottom plate, and between the side plates; the graphite square columns, the bottom plate and the side plates are all provided with connection holes, and the bottom plate, the side plates and the graphite square columns are fixedly connected by the screws and the connection holes. The graphite sagger has a simple structure, is easy to process, and has a greatly reduced cost. The application of the graphite square columns makes the overall mechanical properties of the graphite sagger very excellent, overcoming the stress concentration problem of the corners of the graphite sagger in the prior art. However, the patented combined graphite sagger is connected by bolts, which is prone to loosening, has a short service life, and has problems such as leakage, cracking, and fracture at the joints. The rotating connecting turntable is designed in the middle of the top surface, and each turntable is connected to the corresponding notched clamping ring through a limiting mechanism. The structure is complex and the mass production efficiency is low, which cannot meet the market demand.

[0004] A Chinese utility model patent discloses a combined graphite sagger (publication number: CN218545311U), which adopts a large-area dovetail groove and a dovetail structure to achieve mutual combination. It is processed by graphite material. Due to its thick thickness, it can be spliced ​​through large dovetail grooves and dovetails. Once the thickness requirement is stricter, when the wall thickness of about 7mm is adopted, the dovetail grooves and dovetail structures arranged in this way are difficult to process on the one hand, and on the other hand, they affect the strength of the structure, because the large-area grooves on the thinner plate will affect the strength.

[0005] Therefore, the technical problems to be solved by the utility model patent are the high cost of the existing integrated sagger, the poor structural properties of the spliced ​​sagger, the short lifespan, etc. In addition, the thinning thickness is conducive to the user to increase the output and achieve the purpose of reducing costs and increasing efficiency.

More preferably, the N2 side plates are symmetrically distributed, so that the sagger is a regular quadrilateral, a regular hexagon, a regular octagon...a regular N2 polygon;

[0045] Each of the edges 11 of the cardinality is provided with a side plate Ⅰ2. Taking N2 as 4 as an example, the first edge 11 and the third edge 11 are provided with a side plate Ⅰ2, and the edge 11 of the cardinality is provided with a limiting structure Ⅰ111, and the corresponding side plate Ⅰ2 is provided with a limiting matching structure Ⅰ21 that matches the limiting structure Ⅰ111. After the limiting structure Ⅰ111 and the limiting matching structure Ⅰ21 match, the bottom plate 1 and the side plate Ⅰ2 are limited in the thickness direction of the bottom plate 1 (refer to the attached Figure 1 Relative movement in the Z direction;

[0046] Each even-numbered side 11 is provided with a side plate II3. Taking N2 as 4 as an example, the second side 11 and the fourth side 11 are provided with side plates II3, and the even-numbered sides 11 are provided with a limiting structure II112. The corresponding side plate II3 is provided with a limiting matching structure II31 that matches the limiting structure II112. After the limiting structure II112 matches the limiting matching structure II31, the bottom plate 1 and the side plate II3 are limited along the plane direction of the bottom plate 1 (refer to the attached Figure 1 The bottom plate 1 and the side plate II3 are allowed to move relative to each other along the thickness direction of the bottom plate 1 (see the attached Figure 1 Relative movement in the Z direction;

[0047] The side edge of the side plate I2 is provided with a limiting structure III22, and the side edge of the side plate II3 is provided with a limiting matching structure III32 that matches the limiting structure III22. After the limiting structure III22 and the limiting matching structure III32 match, the side plate I2 and the side plate II3 are limited in the thickness direction of the side plate I2 (refer to the attached Figure 1 Relative movement in the X direction;

[0048] The side of the side plate I2 is also provided with a limiting groove I23 connected to the limiting structure III22, and the side of the side plate II3 is also provided with a limiting groove II33 connected to the limiting matching structure III32. Figure 1After the limit groove I23 and the limit groove II33 are moved and matched, the limit groove I23 and the limit groove II33 are connected, and the limit block 4 is embedded in the limit groove I23 and the limit groove II33, and the limit block 4 limits the side plate I2 and the side plate II3 along the thickness direction of the bottom plate 1 (refer to the attached Figure 1 Relative movement in the Z direction;

[0049] After the limit block 4 is installed, the limit block 4 and the limit structure III22 and the limit matching structure III32 limit the movement of the side plate II3 in the Z direction. At this time, the limit structure II112 and the limit matching structure II31 limit the movement of the side plate II3 in the X direction and the Y direction, and the side plate II3 is locked on the bottom plate 1 and the side plate I2. At the same time, the limit structure III22 and the limit matching structure III32 limit the movement of the side plate I2 in the Y direction and the X direction, and the limit structure I111 and the limit matching structure II31 limit the movement of the side plate I2 in the Z direction. They restrict and lock each other. Finally, N1 side plates I2, N1 side plates II3, the bottom plate 1 and the limit block 4 cooperate to form the sagger with zero degree of freedom.

[0050] The sagger provided by the utility model is composed of multiple plates and multiple limit blocks 4. It only needs to process different grooves and protrusions on the plates to form the above-mentioned limit structures and limit matching structures. Through a specific installation sequence, multiple plates can be mutually restricted and locked to finally form a sagger with zero degree of freedom. No fasteners are required, and no through holes required for fastening are required. Therefore, there will be no loosening, short service life, cracking, and fracture problems. In addition, the sagger provided by the utility model, after multiple limit structures and limit matching structures and the limit blocks 4 are matched with the limit grooves Ⅰ23 and the limit grooves Ⅱ33, the inner wall and outer wall of the sagger are both planar structures, so it is equivalent to a standard sagger, without any redundant materials, and provides a sagger that is fixed by locking the plates together, has a simple structure, is easy and quick to assemble, has a stable and reliable structure, and does not add any materials.

[0051] In an exemplary embodiment, the limiting structure I111 is a dovetail groove or a dovetail, and the limiting matching structure I21 is a dovetail or a dovetail groove, that is, when the limiting structure I111 is a dovetail groove, the limiting matching structure I21 is a dovetail, and vice versa, when the limiting structure I111 is a dovetail, the limiting matching structure I21 is a dovetail groove; in this embodiment, the limiting structure I111 and the limiting matching structure I21 adopt the matching relationship of the dovetail groove and the dovetail, which can achieve that both can only move along the Y direction, and are limited in other directions, and have an anti-fool effect. Note that the utility model is not limited to the limiting structure I111 and the limiting matching structure I21 using dovetail grooves and dovetails, and similar limiting structures with limiting functions such as convex grooves and convex blocks can also be used.

[0052] In one of the embodiments, the limiting structures Ⅰ111 and the limiting matching structures Ⅰ21 are arranged in multiple groups along the length direction of the edge 11, thereby strengthening the connection strength between the side panel Ⅰ2 and the bottom panel 1.

[0053] In one embodiment, the limiting structure II112 is a slot or a block, and the limiting matching structure II31 is a block or a slot, that is, when the limiting structure II112 is a slot, the limiting matching structure II31 is a block, and vice versa, when the limiting structure II112 is a block, the limiting matching structure II31 is a slot. Preferably, the slot and the block are matched, and then after the slot and the block match, the side plate II3 can be limited to move in the X direction and the Y direction. When they are not matched, the limiting in the X direction and the Y direction is achieved by the two adjacent side plates I and their limiting structures III22 and limiting matching structure III32. The depth direction of the slot is in the same direction as the thickness direction of the bottom plate 1, so that the side plate II3 can only move in the Z direction. In addition, the matching of the slot and the block can also extend the gap path length between the side plate II3 and the bottom plate 1 to avoid material leakage.

[0054] In one of the embodiments, the limiting structure II112 and the limiting matching structure II31 are arranged in multiple groups along the length direction of the edge 11, thereby strengthening the connection strength between the side panel II3 and the bottom panel 1.

[0055] In one embodiment, the limiting structure III22 is a single-sided dovetail groove or a single-sided dovetail, and the limiting matching structure III32 is a single-sided dovetail or a single-sided dovetail groove, that is, when the limiting structure III22 is a single-sided dovetail groove, the limiting matching structure III32 is a single-sided dovetail, and vice versa, when the limiting structure III22 is a single-sided dovetail, the limiting matching structure III32 is a single-sided dovetail groove; one end of the single-sided dovetail groove is an oblique groove, and the other end is a straight groove; one end of the single-sided dovetail is an oblique block, and the other end is a straight block; after the oblique block of the single-sided dovetail is matched with the oblique groove of the single-sided dovetail groove, there is a gap between the straight fast end of the single-sided dovetail and the straight groove end of the single-sided dovetail groove, that is, the size of the single-sided dovetail groove is longer than that of the single-sided dovetail, at this time, the single-sided dovetail can be inserted into the single-sided dovetail groove along the Z direction for matching, and can also be moved along the opposite direction of Z to make the single-sided dovetail out of the matching of the single-sided dovetail groove;

[0056] When the limiting structure III22 is a single-sided dovetail groove, refer to the attached Fig. 9 The limiting groove Ⅰ23 is an L-shaped groove arranged at the end of the single-sided dovetail groove, refer to the attached Figure 6 , the limiting groove II 33 is formed by the interval between the single-sided dovetail and the end of the single-sided dovetail groove;

[0057] Alternatively, when the limiting matching structure III 32 is a single-sided dovetail, the limiting groove I 23 is formed by the interval between the single-sided dovetail and the end of the single-sided dovetail groove, and the limiting groove II 33 is an L-shaped groove arranged at the end of the single-sided dovetail groove;

[0058] After the single-sided dovetail and the single-sided dovetail groove are matched, the limiting groove I23 and the limiting groove II33 are aligned, and the limiting block 4 fills the notches of the limiting groove I23 and the limiting groove II33, wherein the limiting block is an L-shaped structure, one part of which is matched with the limiting groove I23, and the other part is matched with the limiting groove II33, and limits the single-sided dovetail and the single-sided dovetail groove along the thickness direction of the bottom plate 1 (i.e. Figure 1 In this embodiment, the single-sided dovetail is a protrusion on the side of the side plate, and the single-sided dovetail groove is a groove on the side plate opposite to the side plate. At this time, the side surface of the side plate with the single-sided dovetail is matched in parallel with the end surface of the side plate with the single-sided dovetail groove. At this time, after the limit block 4 is matched with the limit groove I 23 and the limit groove II 33, the gap formed by the interval between the L-shaped groove and the single-sided dovetail and the end of the single-sided dovetail groove is made up, thereby ensuring the integrity of the sagger.

[0059] In one embodiment, a limiting structure IV24 is further provided on the side of the side panel I2, and a limiting matching structure IV34 matching with the limiting structure IV24 is further provided on the side of the side panel II3. The limiting structure IV24 and the limiting matching structure IV34 are slidably engaged with each other along the thickness direction of the bottom plate 1, so that the engagement of the limiting structure III22 and the limiting matching structure III32 can be realized synchronously. After the limiting structure IV24 and the limiting matching structure IV34 are engaged, the side panels I2 and II3 are limited in the thickness direction of the side panels II3 (attached Figure 1 Such arrangement can, on the one hand, enhance the structural strength of the limit fixation, and on the other hand, extend the gap path length between the side plate II3 and the side plate I2 to avoid material leakage.

[0060] In one embodiment, the limiting structure IV24 is a vertical protrusion disposed toward the side plate II3, and the limiting matching structure IV34 is a vertical groove disposed toward the side plate I2;

[0061] Alternatively, the limiting structure IV24 is a vertical groove arranged toward the side plate II3, and the limiting matching structure IV34 is a vertical protrusion arranged toward the side plate I2. The matching of the vertical protrusion and the vertical groove increases the matching area, improves the stability of the connection and improves the effect of avoiding material leakage.

[0062] In one embodiment, the limiting structure IV24 is provided with a group at the upper and lower ends of the side plate I2, and the limiting matching structure IV34 is provided with a group at the upper and lower ends of the side plate II3, so as to further improve the stability of the connection and improve the effect of avoiding leakage.

[0063] In one of the embodiments, the bottom plate 1, side plate I2, side plate II3 and limit block 4 are made of carbon-carbon composite material.

[0064] The utility model also provides a method for assembling the above-mentioned sagger, which is characterized by comprising the following steps:

[0065] S1, through the cooperation of the limiting structure I111 and the limiting matching structure I21, one of the side panels I2 is installed on each cardinality of the edge 11 of the bottom plate 1, at this time, the side panel I2 can only move toward the outside of the bottom plate 1;

[0066] S2, the side plate II3 moves toward the bottom plate 1 along the thickness direction of the bottom plate 1 ( Figure 1 The limiting structure II112 and the limiting matching structure II31 as well as the limiting structure III22 and the limiting matching structure III32 are matched at the same time. At this time, the limiting groove I23 and the limiting groove II33 are connected; and the side plate II3 can only move away from the bottom plate 1 along the thickness direction of the bottom plate 1 ( Figure 1 Z direction shown);

[0067] S3, repeat step S2 to complete the installation of all side panels II3;

[0068] S4, embed the limit block 4 into the limit groove Ⅰ23 and the limit groove Ⅱ33 to limit the movement of the side plate Ⅱ3 along the thickness direction of the bottom plate 1. At this time, the degree of freedom of the bottom plate 1, N1 side plates Ⅰ2 and N1 side plates Ⅱ3 is zero.

[0069] The assembling method of the sagger does not require the aid of fastening tools and can be completed by manual labor combined with lifting equipment. The entire assembly process is convenient and fast.

[0070] In one embodiment, the following steps are also included:

[0071] S5, treating the joints of the assembled saggers, such as bonding or filling with fillers, to improve the connection stability and the leak-proof effect.

[0072] In the embodiment with the limiting structure IV24 and the limiting matching structure IV34, before step S1, the side panel II3 is first placed between two adjacent side panels I2, and the side panel II3 is higher than the two side panels I2 by a distance of a limiting groove II33. At this time, the limiting structure IV24 and the limiting matching structure IV34 are matched with each other along the thickness direction of the side panel I2 by bringing the two side panels I2 closer to each other, so as to complete the matching of the limiting structure IV24 and the limiting matching structure IV34.

[0073] The above is only an embodiment and does not limit the present invention in any way.
