Description

Technical Field

[0001] This utility model relates to the field of refractory brick technology, and in particular to an irregularly shaped refractory brick. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials with specific shapes and sizes. Based on their manufacturing process, refractory bricks can be classified into fired bricks, unfired bricks, electrofused bricks (cast bricks), and refractory insulating bricks; based on their shape and size, they can be classified into standard bricks, common bricks, and special-shaped bricks. They can be used as high-temperature building materials and structural materials for kilns and various thermal equipment, and can withstand various physicochemical changes and mechanical actions at high temperatures.

[0003] Patent document CN202122455196.1 discloses an irregularly shaped refractory brick. In this design, when two sets of irregularly shaped refractory bricks are joined in parallel, a protrusion is inserted into a groove. Before insertion, a fixing rod is placed in a circular hole, and the bottom of the hole is blocked with one hand. The circular hole and fixing rod are then slowly inserted into the groove. The fixing rod slides within the groove, moving to one side with the protrusion. After the protrusion is fully inserted into the groove, the fixing rod slides down into the groove, acting as a stop and limiter to prevent the protrusion and groove from falling off. While this irregularly shaped refractory brick is easy to connect, its relatively large size makes it inconvenient to handle during stacking and movement, and it is prone to slipping during stacking. Therefore, improvements to the irregularly shaped refractory brick are needed to address this issue. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem that irregularly shaped refractory bricks are inconvenient to handle and easy to slip during stacking and moving in the prior art. Therefore, this utility model proposes an irregularly shaped refractory brick.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An irregularly shaped refractory brick includes a brick body, one end of which is provided with an insert block, and one end of the top of the brick body is provided with a limiting groove that cooperates with the insert block. Two sets of protrusions are installed on the upper surface of the brick body, with two protrusions in each set. One protrusion has a thumb hole and the other protrusion has a four-finger hole.

[0007] In some embodiments, the insert block is provided with a first serrated groove on both sides, and the limiting groove is provided with a second serrated groove on both sides, wherein the first serrated groove and the second serrated groove cooperate with each other.

[0008] In some embodiments, the bottom of the brick body has a groove that matches the protrusion.

[0009] In some embodiments, two sets of protrusions are symmetrically arranged on both sides of the brick body along its length, and two protrusions in the same set are symmetrically arranged on both sides of the brick body along its width.

[0010] In some embodiments, the longitudinal section of the insert is T-shaped.

[0011] In some embodiments, a weight-reducing hole is provided through the upper surface of the brick body, and the weight-reducing hole is configured as two holes and evenly distributed on the upper surface of the refractory brick body.

[0012] In some embodiments, both the thumb hole and the four-finger hole are inclined.

[0013] Compared with the prior art, the present invention provides an irregularly shaped refractory brick, which has the following beneficial effects.

[0014] This invention facilitates the handling of bricks by using the thumb hole and four-finger hole on the protrusion. The worker inserts their thumb into the thumb hole and the other fingers into the four-finger hole to pick up the brick. Then, one end of the brick with the insert block is inserted into the other end of the brick with the limiting groove. At the same time as insertion, the second serrated groove and the first serrated groove are locked together, enabling quick installation between the two irregularly shaped refractory bricks, improving the assembly efficiency, and achieving a fast and stable splicing effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A type of irregularly shaped refractory brick includes a brick body 1. One end of the brick body 1 has an insert block 2, and the top end of the brick body 1 has a limiting groove 3 that mates with the insert block 2. Two sets of protrusions 4 are installed on the upper surface of the brick body 1, with two protrusions in each set. One protrusion 4 has a thumb hole 5, and the other protrusion 4 has a four-finger hole 6. Through this structure, the thumb hole 5 and the four-finger hole 6 on the protrusions 4 work together to facilitate the handling of the brick body 1. The worker inserts their thumb into the thumb hole 5 and then inserts the remaining fingers into the four-finger hole 6 to pick up the brick body 1, making it easier to handle and move, thus improving safety during use.

[0026] Furthermore, the insert block 2 has a first serrated groove 7 on both sides facing each other, and the limiting groove 3 has a second serrated groove 8 on both sides facing each other, with the first serrated groove 7 and the second serrated groove 8 cooperating with each other.

[0027] Please refer to this again. Figure 3 The bottom of the brick 1 is provided with a groove 9 that matches the protrusion 4. One brick 1 is placed on top of another brick 1, so that the protrusion 4 is inserted into the groove 9, thereby completing the combination of brick 1 and brick 1.

[0028] In this embodiment, two sets of protrusions 4 are symmetrically arranged on both sides of the brick body 1 along its length, and two protrusions 4 in the same set are symmetrically arranged on both sides of the brick body 1 along its width, which facilitates staggered installation between brick bodies 1.

[0029] Specifically, the longitudinal section of the insert 2 is T-shaped, and the limiting groove 3 cooperates with the insert 2. When the insert 2 is inserted into the limiting groove 3, it prevents the joint of the brick body 1 from shaking.

[0030] It is worth mentioning that two weight-reducing holes 10 are provided through the upper surface of the brick body 1, and these holes are evenly distributed on the upper surface of the refractory brick body. By providing weight-reducing holes 10, it is possible to reduce the weight of the irregularly shaped refractory brick without affecting its use.

[0031] Please refer to this again. Figure 4 Both the thumb hole 5 and the four-finger hole 6 are angled. This makes it easy to insert the thumb into the thumb hole 5 or the other fingers into the four-finger hole 6.

[0032] The working principle of this utility model is as follows:

[0033] This invention facilitates the handling of brick 1 by using the thumb hole 5 and four-finger hole 6 on the protrusion 4. Specifically, the worker inserts their thumb into the thumb hole 5 and then inserts the remaining fingers into the four-finger hole 6 to pick up the brick 1, making it easier to handle and move, thus improving safety. Then, one end of one brick 1 with the insert block 2 is inserted into the end of another brick 1 with the limiting groove 3. Simultaneously, the second serrated groove 8 engages with the first serrated groove 7, allowing for quick installation between the two irregularly shaped refractory bricks and further improving the stability of the assembled irregularly shaped refractory bricks.

[0034] After the same layer of irregularly shaped refractory bricks is assembled, one brick 1 is placed on top of another brick 1, so that the protrusion 4 is inserted into the groove 9, thereby completing the combination of brick 1 and brick 1.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
