Description

Technical Field

[0001] The utility model belongs to the field of couplet production, and particularly relates to a ceramic couplet. Background Art

[0002] Currently, the materials for making couplets include paper, wooden boards, bamboo boards, metal plates, etc. These couplets made of these materials all have common defects: they will fade, deteriorate, and rot after a long time, affecting the beauty. Especially when applied to outdoor scenes such as scenic spots, the above-mentioned defects will occur soon after being exposed to sunlight and rain.

[0003] For the couplets of the prior art, due to the light weight of the materials used, they are relatively easy to install, and can be glued or hung with hanging rings. Summary of the Utility Model

[0004] In view of the above problems, the utility model aims to provide a couplet that does not fade, is not easy to deteriorate, and does not rot.

[0005] The vocabulary mentioned in this case is defined as follows:

[0006] Couplet body: a carrier for carrying works such as characters or paintings. In this case, the carrier is fired ceramics.

[0007] Body segment: having the same material as the couplet body, and can be regarded as small segments obtained by dividing the couplet body. At least two body segments are butted together to form a complete couplet body.

[0008] Non-display surface: on the couplet body, at least one surface is used to carry works such as characters and paintings, which is called the display surface. On the contrary, the surface that is not used to carry works is called the non-display surface.

[0009] In addition, the up, down and other direction words, as well as the length, width, thickness and other words of the couplet mentioned in this case are referenced with the state when the couplet is normally hung, which conforms to the daily life habits and is the direction determined for the convenience of description, and does not constitute a limitation on the structure.

[0010] The technical solution for the utility model to solve the problem is:

[0011] A couplet, comprising:

[0012] A couplet body, the couplet body being made of ceramic material; blind holes are opened on the non-display surface of the couplet body;

[0013] A supporting member, a bonding layer is provided between the supporting member and the non-display surface of the couplet body, and the bonding layer bonds and fixes the supporting member and the couplet body; through holes are provided on the supporting member corresponding to the positions of the blind holes;

[0014] A hanging part, the hanging part is fixedly connected to the supporting member;

[0015] An anchoring assembly, which includes an anchoring rod fixedly arranged in a blind hole and passing through a through hole, and a locking member that cooperates with the anchoring rod to lock the supporting member and the couplet body.

[0016] In the above solution, the couplet body is made by high-temperature firing of ceramic materials. The characteristics of ceramics determine that the works on the display surface of the couplet will never fade, the couplet is not easy to deteriorate or rot, has a long service life, and the aesthetic degree remains unchanged throughout the life cycle.

[0017] During the firing process of the ceramic couplet, there are extremely many technological problems to be overcome. For example, during the high-temperature firing process of the long strip-shaped clay blank, problems such as cracking, warping, and deformation caused by uneven shrinkage of the blank will occur, and there are also problems such as uneven internal and external heat absorption due to the excessive thickness of the clay blank. It is precisely because of these problems that no one has ever invented a couplet made of ceramic materials since the couplet appeared thousands of years ago.

[0018] After the inventor of this case invented the ceramic couplet, a new problem arose: Since ceramic is used as the material of the couplet body, its weight is much heavier than that of traditional materials, and it is difficult to hang. Subsequently, in response to this further encountered problem, structural designs such as a supporting member and an anchoring assembly are adopted to improve the hanging safety.

[0019] Further, the couplet body is spliced by at least two body segments, and grooves are opened on the opposite end faces of adjacent two body segments;

[0020] It further includes a connecting member. The two ends of the connecting member are respectively inserted into the grooves of two adjacent body segments, and the connecting member is fixedly connected with the inner wall of the groove through an adhesive;

[0021] The opposite end faces of adjacent two body segments are fixedly connected through an adhesive.

[0022] The above further solution is a solution to reduce the production cost. Because the couplet is relatively long, the process of making an integral couplet body is difficult, the finished product rate is slightly low, the clay blank is difficult to form and wastes a lot. Therefore, using ceramic to fire body segments with small sizes and splicing multiple body segments into a couplet body is more conducive to reducing costs and production difficulties.

[0023] Further, the thickness of the couplet body is greater than or equal to 2 cm. The ceramic couplet of the present utility model is different from other ceramic paintings, ceramic tiles, etc. with a thickness within 8 mm. The thickness is not less than 2 cm. On the one hand, it is the requirement of the production process, and on the other hand, it focuses more on outdoor application scenarios to ensure the product strength.

[0024] Further, the weight of the couplet body is greater than or equal to 30 catties.

[0025] Preferably, the lower end length of the supporting member exceeds the lower end length of the couplet body, and / or,

[0026] A rubber pad is provided at the lower end of the supporting member.

[0027] This preferred solution is to prevent the ceramic couplet body from being damaged when accidentally falling. When falling, the lower end of the supporting member first touches the ground, playing a certain buffering role. Or the rubber pad plays a buffering role.

[0028] Furthermore, the blind hole is made by drilling. For a ceramic couplet, it is impossible to open holes before firing, otherwise, due to the shrinkage of the mud blank during the firing process, the hole diameter will change or the hole will be deformed. Therefore, it is necessary to drill holes after firing into ceramics. However, drilling holes in ceramics is extremely difficult and often causes the ceramics to crack. So, this case adopts a new drilling method.

[0029] Preferably, the blind hole is made by submerging the couplet body in water and then drilling.

[0030] Specifically, the locking member is a nut, and the outer diameter of the nut is larger than the aperture of the through hole;

[0031] The anchoring rod is a threaded rod. One end of the anchoring rod is fixedly connected to the inner wall of the blind hole through an adhesive, and the other end of the anchoring rod passes through the through hole and is in threaded cooperation with the locking member to lock the supporting member and the couplet body.

[0032] Specifically, the hanging part is a hanging ring, which is arranged at the upper end of the supporting member.

[0033] Specifically, the connecting member is a metal block. The connecting member plays a role in pulling adjacent body segments.

[0034] Preferably, the width of the supporting member is the same as that of the couplet body. Generally, the supporting member is provided on the back of the ceramic couplet body, and the two side surfaces and the upper and lower end surfaces of the couplet body do not need to be provided, which are the display surfaces that can be shown.

[0035] The method for making a ceramic couplet includes the following steps:

[0036] A) Fire the ceramic couplet body, and then carve works on the display surface of the couplet body;

[0037] In this step, a disc-shaped mud blank must be fired into ceramics and then cut into the shape of a couplet; the cutting step can be carried out before or after carving the works;

[0038] C) Fix the hanging part and the supporting member; bond the couplet body and the supporting member with a through hole through an adhesive, and open blind holes on the non-display surface of the couplet body; the timing of the fixed connection between the hanging part and the supporting member can be carried out at any time before the bonding of the couplet body and the supporting member;

[0039] There are two processes for opening blind holes in this step:

[0040] The first process: a) Drilling blind holes is carried out before bonding the couplet body to the supporting member. The process is as follows: immerse the couplet body in water, and directly drill blind holes on the non-display surface of the couplet body with a drill bit by means of underwater drilling. Then, bond the non-display surface of the couplet body with drilled blind holes to the supporting member with through holes through an adhesive, and wait for the adhesive to dry completely.

[0041] The second process: b) Drilling blind holes is carried out after bonding the couplet body to the supporting member. The process is as follows: bond the non-display surface of the couplet body to the supporting member with through holes through an adhesive, and after the adhesive dries completely, directly drill blind holes at the through holes with a special drill bit. During the drilling process, coolant must be continuously used for cooling.

[0042] D) Installing the anchoring component. The process is as follows: after the couplet body and the supporting member have been firmly bonded, apply glue in the blind holes, then insert one end of the anchor rod into the blind hole and keep the other end of the anchor rod passing through the through hole. After the anchor rod inserted into the blind hole is firmly bonded in the blind hole, the supporting member and the couplet body are fitted and locked through a locking member.

[0043] As mentioned above, during the firing process of the ceramic couplet, problems such as cracking and warping of the long strip-shaped clay blank will occur during the high-temperature firing process, resulting in no one ever inventing a ceramic couplet. In the above step A), firing the ceramic with a disc-shaped clay blank is one of the important innovations of this case. Since the disc-shaped clay shrinks equally during the high-temperature firing process, the fired ceramic does not crack or warp, and the yield is high.

[0044] How to drill holes is another important innovation of the present utility model. If holes are directly drilled on the couplet body, cracks are easily drilled. The drilling method of the first process a) of the present utility model not only does not produce cracks, but also due to the drill bit being immersed in water, the cooling condition is good, and the service life of the drill bit is longer. In the second process b) of the present utility model, due to the constraint of the supporting member and the adhesive on the couplet body, and the adhesive layer itself has a certain flexibility and has a shock-absorbing effect, cracks are not easily generated during the drilling process.

[0045] In a preferred solution, when the couplet body is composed of at least two body segments, after step A) and before step C), it further includes:

[0046] Step B) splicing the body segments into an integral couplet body. The process includes opening grooves on the opposite end faces of each adjacent two body segments, respectively inserting the two ends of the connecting member into the grooves of the two adjacent body segments, and fixedly connecting the connecting member to the inner wall of the groove through an adhesive; then fixedly connecting the opposite end faces of the adjacent body segments through an adhesive, positioning and pressing the bonding seam on a fixture, and waiting for the adhesive to dry completely.

[0047] In a preferred embodiment, the locking member in step D) is a nut, and the outer diameter of the nut is greater than the aperture of the through hole; the anchoring rod is a threaded rod, and the anchoring rod is in threaded engagement with the locking member to tightly lock the supporting member and the couplet body together.

[0048] The remarkable effects of the present utility model are as follows:

[0049] First, a ceramic couplet that is not afraid of sun and rain and whose display surface of the couplet never fades is proposed. This kind of couplet is not easy to deteriorate or rot, has a long service life, and maintains its aesthetic appearance throughout its life cycle.

[0050] Second, in view of the characteristics that the ceramic couplet body is heavy and thick, a structure and manufacturing method that can improve the hanging safety are designed. The supporting member is bonded to the couplet body, and at the same time, it is tightly locked through the anchoring assembly to form a double fixation structure, ensuring that such a heavy ceramic couplet body can be hung.

[0051] Third, in view of the difficulty in drilling holes in ceramics and the easy occurrence of cracks before installing the anchoring assembly, the first process a) of underwater drilling is adopted, which can avoid the occurrence of cracks, has a high passing rate of drilling, and increases the service life of the drill bit. The second process b) of drilling is adopted, and cracks are not easily generated during the drilling process. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0060] Embodiment 1

[0061] As Figures 1 to 3 shown, where Figure 1 what is seen is the back side, and the front side is not shown. The front side is the display surface carrying the work. A couplet includes a couplet body 1, blind holes 2, a supporting member 3, an adhesive layer 4, a hanging part 5, and an anchoring assembly 6.

[0062] The couplet body 1 is made of ceramic material. Blind holes 2 are formed on the non-display surface of the couplet body 1.

[0063] An adhesive layer 4 is provided between the supporting member 3 and the non-display surface of the couplet body 1. The adhesive layer 4 bonds and fixes the supporting member 3 and the couplet body 1. Through holes are provided on the supporting member 3 corresponding to the positions of the blind holes 2. The material of the supporting member 3 is preferably a stainless steel plate.

[0066] Specifically, the locking member 62 is a nut, such as a flange nut, and the outer diameter of the nut is larger than the aperture of the through hole.

[0067] The anchoring rod 61 is a threaded rod. One end of the anchoring rod 61 is fixedly connected to the inner wall of the blind hole 2 through an adhesive, and the other end of the anchoring rod 61 passes through the through hole and is in threaded cooperation with the locking member 62 to lock the supporting member 3 and the couplet body 1.

[0068] The thickness of the couplet body 1 is 3 - 5 cm.

[0069] The weight of the couplet body 1 is 30 - 50 catties.

[0070] To increase buffering and avoid cracking after falling, the lower end length of the supporting member 3 exceeds the lower end length of the couplet body 1, and / or

[0071] a rubber pad is provided at the lower end of the supporting member 3.

[0072] The suspension part 5 is a hanging loop and is arranged at the upper end of the supporting part 3.

[0073] The width of the supporting part 3 is the same as that of the couplet body 1. That is, the supporting part can be arranged on the back of the ceramic couplet body 1, and it is not necessary to arrange it on the two side surfaces and the upper and lower end surfaces of the couplet body 1, which are the display surfaces that can be shown.

[0074] The method for manufacturing the ceramic couplet in this embodiment includes the following steps:

[0075] A) Fire the ceramic couplet body 1, and then carve works on the display surface of the couplet body 1;

[0076] In this step, it is necessary to use a disc-shaped clay blank to fire into ceramics and then cut it into the shape of a couplet; the cutting step can be carried out before or after carving the works;

[0077] C) Fix and connect the suspension part 5 and the supporting part 3; bond the couplet body 1 and the supporting part 3 with a through hole through an adhesive, and drill blind holes 2 on the non-display surface of the couplet body 1; the fixing and connecting time of the suspension part 5 and the supporting part 3 can be carried out at any time before the couplet body 1 and the supporting part 3 are bonded;

[0078] There are two processes for drilling the blind holes 2 in this step:

[0079] The first process a) Drilling the blind holes is carried out before bonding the couplet body 1 and the supporting part 3. The process is to immerse the couplet body 1 in water and directly drill the blind holes 2 on the non-display surface of the couplet body 1 by using a drill bit in the way of underwater drilling, and then bond the non-display surface of the couplet body 1 with the drilled blind holes 2 and the supporting part 3 with a through hole through an adhesive and wait for the adhesive to dry completely;

[0080] The second process b) Drilling the blind holes is carried out after bonding the couplet body 1 and the supporting part 3. The process is to bond the non-display surface of the couplet body 1 and the supporting part 3 with a through hole through an adhesive, and after the adhesive dries completely, directly drill the blind holes 2 at the through hole with a special drill bit, and the coolant must be continuously cooled during the drilling process;

[0081] D) Install the anchoring assembly 6. The process is that after the couplet body 1 and the supporting part 3 are firmly bonded, apply glue in the blind holes 2, then insert one end of the anchor rod 61 into the blind holes 2 and keep the other end of the anchor rod 61 passing through the through hole. After the anchor rod 61 inserted into the blind holes 2 is firmly bonded in the blind holes 2, make the supporting part 3 and the couplet body 1 fit and lock through the locking part 62.

[0082] Embodiment 2

[0083] The solution of this embodiment is basically the same as that of Embodiment 1, and the differences are as follows: As Figures 4 - 5As shown, the couplet body 1 is formed by splicing at least two body segments 11. Grooves 12 are formed on the facing end faces of two adjacent body segments 11. A connecting member 7 is further included. The two ends of the connecting member 7 are respectively inserted into the grooves 12 of two adjacent body segments 11, and the connecting member 7 is fixedly connected to the inner wall of the groove 12 through an adhesive; the facing end faces of two adjacent body segments 11 are fixedly connected through an adhesive.

[0084] The corresponding processing technology for the above structural solution further includes, after step A) and before step C) in Embodiment 1:

[0085] Step B) Splice the body segments 11 into an integral couplet body 1. The process includes forming grooves 12 on the facing end faces of every two adjacent body segments 11, respectively inserting the two ends of the connecting member 7 into the grooves 12 of two adjacent body segments 11, and fixedly connecting the connecting member 7 to the inner wall of the groove 12 through an adhesive; then fixedly connecting the facing end faces of adjacent body segments 11 through an adhesive, keeping the adhesive joint positioned and tightened on a fixture, and waiting for the adhesive to dry completely.

[0086] The connecting member 7 is a metal block. The connecting member 7 serves to pull adjacent body segments.

[0087] Embodiment 2 is a solution for reducing production costs. Since the couplet is relatively long, the process of manufacturing an integral couplet body is difficult, the yield rate is slightly low, the forming of the clay blank is difficult, and there is a lot of waste. Therefore, using ceramic firing to make body segments 11 with small sizes and splicing multiple body segments 11 into a couplet body 1 is more conducive to reducing costs and manufacturing difficulty.

[0088] It should be noted that the terms "include" and "have" and any of their variations are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.
