Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a hinge for a ceramic oven. Background Technology

[0002] A ceramic oven is an oven that uses ceramic material as its main structure or cooking surface. The hinge of a ceramic oven is a key component that connects the oven door and the oven body. It allows the oven door to open and close smoothly and ensures the stability and safety of the oven door.

[0003] Currently, the hinges of ceramic ovens are prone to jamming and damage due to increased friction coefficients in the bearings and opening / closing shafts over prolonged use, affecting the user experience and reducing overall product performance and user experience. Furthermore, the spring components are susceptible to damage and loss of elasticity due to high oven temperatures, corrosive substances, and prolonged use, thus reducing their durability. Therefore, those skilled in the art have provided a hinge for ceramic ovens to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hinge for a ceramic oven. Through the inclusion of a lubrication device, the hinge effectively lubricates the contact surfaces of the bearing and its inner ring with the hinge shaft, reducing the coefficient of friction and preventing jamming and uneven operation during prolonged use, which could damage the product and negatively impact the user experience. This improves overall product performance and user experience while reducing maintenance costs. Furthermore, the cobalt-based alloy spring assembly provides high-temperature stability, corrosion resistance, and fatigue resistance, enabling continuous operation in high-temperature environments. It also prevents the spring assembly from being corroded by corrosive substances and maintains its elasticity, thus enhancing its durability. Finally, the protective ceramic coating provides extremely high hardness, high-temperature resistance, and a certain degree of corrosion resistance, preventing deformation or damage during daily use and further improving the equipment's durability and reliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hinge for a ceramic oven, comprising a lower hinge cover and an upper hinge cover. The upper hinge cover is fitted inside the lower hinge cover, near the upper center. An opening / closing shaft is located at the lower front end of the upper hinge cover. Bearings are located on both sides of the outer center of the opening / closing shaft. Arc-shaped grooves are located at the rear rear end of the upper center of both side walls of the lower hinge cover. An upper cover shaft pressure rod is located at the rear rear end of the lower center of the upper hinge cover. Grooves are located at the front and rear rear ends of the lower center of both sides of the lower hinge cover. A lower cover shaft fixing rod is located at the lower center of the lower hinge cover. Spring shafts are provided on both sides of the center of the end face. Spring assemblies are provided on both sides of the center of the upper end face of the lower cover shaft fixing rod. Upper cover blocks are provided on both sides of the center of the hinge upper cover. Three first connecting holes are arranged horizontally at the center of the front end face of the two upper cover blocks. Lower cover adjusting blocks are provided on the upper side of the center of the two inner side walls of the hinge lower cover. Three second connecting holes are arranged horizontally at the center of the front end face of the two lower cover adjusting blocks. Bolts are provided on the lower side of the center of one side wall of the two lower cover adjusting blocks. Lubrication devices are provided on the upper side of the center of the two sides of the hinge lower cover. A protective coating is provided on the outer surface of the hinge lower cover.

[0006] The above technical solution, through the setting of the lubrication device, enables lubrication of the contact surfaces of the bearing and bearing inner ring with the opening and closing shaft, and reduces the coefficient of friction. This avoids jamming and unevenness during long-term use, which could lead to damage and affect the user experience, thereby improving the overall performance and user experience of the product and reducing maintenance costs.

[0007] Furthermore, the lubrication device includes an oil injection nozzle, a connecting pipe, multiple first through holes, and multiple second through holes. The oil injection nozzle is located at the center of one side of the lower hinge cover. The connecting pipe is located at the output end of the oil injection nozzle, and the output end passes through the lower hinge cover and the upper end face of the bearing outer ring in sequence to the inside of the bearing outer ring. The multiple first through holes are respectively located at the center of the lower inner wall of the bearing outer ring, and the multiple second through holes are respectively located at the center of the upper and lower inner walls of the bearing inner ring.

[0008] The above technical solution delivers lubricating oil to the connecting pipe via the grease nipple, then to the outer ring of the bearing via the connecting pipe, then to the bearing interior via the first through hole, and finally to the inner ring of the bearing and the contact surface between the inner ring and the opening / closing shaft via the second through hole. This ensures lubrication of the bearing and the contact surface between the inner ring and the opening / closing shaft, reduces the coefficient of friction, and prevents jamming and uneven operation during prolonged use, thus avoiding damage and impacting the user experience. This improves the overall performance and user experience of the product and reduces maintenance costs.

[0009] Furthermore, the two ends of the opening and closing shaft pass through the upper hinge cover and the lower hinge cover respectively and extend to the side wall of the lower hinge cover. The opening and closing shaft and the lower hinge cover are rotatably connected by a bearing, and the outer ring of the bearing is fixedly connected to the lower hinge cover.

[0010] The above technical solution enables the opening and closing of the upper and lower hinge covers, as well as the opening and closing of the oven door and the oven body, through the opening and closing shaft and bearing.

[0011] Furthermore, the two ends of the lower cover shaft fixing rod pass through four channels to the outside of the channels and are slidably connected to the four channels respectively;

[0012] The above technical solution allows for the sliding connection between the lower cover shaft fixing rod and the channel, thus enabling the lower cover shaft fixing rod to move.

[0013] Furthermore, both of the lower cover adjusting blocks are L-shaped, and the two bolts pass through the two lower cover adjusting blocks and the hinge lower cover respectively, extending to the outside of the hinge lower cover;

[0014] The above technical solution uses L-shaped lower cover adjustment blocks and bolts to fix the lower cover adjustment blocks to the hinged lower cover and to the oven body.

[0015] Furthermore, both spring assemblies are made of cobalt-based alloys;

[0016] The above technical solution utilizes a spring assembly made of cobalt-based alloy, which possesses high-temperature stability, corrosion resistance, and fatigue resistance, enabling continuous operation in high-temperature environments. This prevents the spring assembly from being corroded by corrosive substances and ensures the retention of elasticity during use, thereby improving the durability of the spring assembly.

[0017] Furthermore, the protective coating is a ceramic coating;

[0018] The above technical solution utilizes a ceramic coating to provide protection, resulting in extremely high hardness, high-temperature resistance, and a certain degree of corrosion resistance. This prevents deformation or damage during daily use, thereby improving the durability and reliability of the equipment.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, when the hinge of the ceramic oven is used, the lubrication device is set to ensure that the contact surface between the bearing and the inner ring of the bearing and the opening and closing shaft is lubricated, and the coefficient of friction is reduced. This avoids jamming and non-smooth operation during long-term use, which would cause damage and affect the user experience. As a result, the overall performance of the product and the user experience are improved, and maintenance costs are reduced.

[0021] 2. In this utility model, the spring assembly, made of cobalt-based alloy, has high-temperature stability, corrosion resistance and fatigue resistance, which meets the requirements for continuous operation in high-temperature environments, avoids the spring assembly from being corroded by corrosive substances, and ensures the elasticity is maintained during use, thereby improving the durability of the spring assembly.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4This utility model provides an embodiment of a hinge for a ceramic oven, comprising a lower hinge cover 1 and an upper hinge cover 2. The upper hinge cover 2 is fitted inside the lower hinge cover 1, near the upper center. An opening / closing shaft 3 is located at the lower front end of the upper hinge cover 2. Bearings 4 are located on both sides of the outer center of the opening / closing shaft 3. Arc-shaped grooves 5 are located at the rear rear end of the upper center of both side walls of the lower hinge cover 1. An upper cover shaft pressure rod 6 is located at the rear rear end of the lower center of the upper hinge cover 2. Grooves 7 are located at the front and rear rear ends of the lower centers of both sides of the lower hinge cover 1. The lower cover 1 has a lower cover shaft fixing rod 8 located at the lower center. The lower end face of the lower cover shaft fixing rod 8 has spring shafts 9 located on both sides. The upper end face of the lower cover shaft fixing rod 8 has spring assemblies 10 located on both sides. The spring assemblies 10 are made of cobalt-based alloy, which gives them high-temperature stability, corrosion resistance and fatigue resistance, allowing them to work continuously in high-temperature environments. This prevents the spring assemblies 10 from being corroded by corrosive substances and ensures that the elasticity is maintained during use, thereby improving the durability of the spring assemblies 10.

[0031] The hinge upper cover 2 has upper cover blocks 11 at the center of both sides. Each upper cover block 11 has three first connecting holes 12 arranged horizontally at the center of its front face. The hinge lower cover 1 has lower cover adjusting blocks 13 at the upper center of both inner side walls. Each lower cover adjusting block 13 has three second connecting holes 14 arranged horizontally at the center of its front face. Bolts 15 are located at the lower end of one side wall of each lower cover adjusting block 13, near the front and rear. Lubrication devices 16 are located at the upper center of both sides of the hinge lower cover 1. The lubrication devices 16 ensure proper lubrication of the bearing 4. The inner ring of the bearing 4 is lubricated on the contact surface with the opening and closing shaft 3, which reduces the coefficient of friction and avoids jamming and unevenness during long-term use, thus preventing damage and affecting the user experience. This improves the overall performance and user experience of the product and reduces maintenance costs. The outer surface of the hinge lower cover 1 is provided with a protective coating 17. The ceramic protective coating 17 gives it extremely high hardness, high temperature resistance and a certain degree of corrosion resistance, preventing deformation or damage during daily use, thereby improving the durability and reliability of the equipment.

[0032] Lubrication device 16 includes an oil nozzle 1601, a connecting pipe 1602, multiple first through holes 1603, and multiple second through holes 1604. The oil nozzle 1601 is located at the center of one side of the hinge lower cover 1. The connecting pipe 1602 is located at the output end of the oil nozzle 1601, and the output end passes through the hinge lower cover 1 and the upper end face of the outer ring of the bearing 4 to the inside of the outer ring of the bearing 4. The multiple first through holes 1603 are respectively located at the center of the lower inner wall of the outer ring of the bearing 4, and the multiple second through holes 1604 are respectively located at the center of the upper and lower inner walls of the inner ring of the bearing 4. Lubricating oil is delivered through the oil nozzle 1601. The lubricant is then conveyed through the connecting pipe 1602 to the outer ring of the bearing 4, then through the first through hole 1603 to the inside of the bearing 4, and then through the second through hole 1604 to the inner ring of the bearing 4 and the contact surface between the inner ring of the bearing 4 and the opening and closing shaft 3. This ensures lubrication of the bearing 4 and the contact surface between the inner ring of the bearing 4 and the opening and closing shaft 3, reduces the coefficient of friction, and prevents jamming and unevenness during long-term use, which could lead to damage and affect the user experience. This improves the overall performance and user experience of the product and reduces maintenance costs.

[0033] The two ends of the opening and closing shaft 3 pass through the upper hinge cover 2 and the lower hinge cover 1 respectively, extending to the side wall of the lower hinge cover 1. The opening and closing shaft 3 and the lower hinge cover 1 are rotatably connected by a bearing 4. The outer ring of the bearing 4 is fixedly connected to the lower hinge cover 1. The opening and closing shaft 3 and the bearing 4 enable the opening and closing between the upper hinge cover 2 and the lower hinge cover 1, and also enable the opening and closing between the oven door and the oven body. The two ends of the lower cover shaft fixing rod 8 pass through four channels 7 respectively, extending to the outside of the channels 7, and are respectively connected to the four channels. The two lower cover adjusting blocks 13 are L-shaped. Two bolts 15 pass through the two lower cover adjusting blocks 13 and the hinge lower cover 1 respectively to the outside of the hinge lower cover 1. The lower cover adjusting blocks 13 are L-shaped, and the bolts 15 pass through them to the outside of the hinge lower cover 1. The lower cover adjusting blocks 13 are L-shaped, and the bolts 15 pass through them to fix the lower cover adjusting blocks 13 and the hinge lower cover 1, and also to fix them to the oven body.

[0034] Both spring assemblies 10 are made of cobalt-based alloy. The cobalt-based alloy material of the spring assemblies 10 gives them high-temperature stability, corrosion resistance, and fatigue resistance, allowing them to work continuously in high-temperature environments. This prevents the spring assemblies 10 from being corroded by corrosive substances and ensures that their elasticity is maintained during use, thereby improving the durability of the spring assemblies 10. The protective coating 17 is a ceramic coating. The ceramic protective coating 17 gives it extremely high hardness, high-temperature resistance, and a certain degree of corrosion resistance, preventing deformation or damage during daily use, thereby improving the durability and reliability of the equipment.

[0035] Working principle: When the hinge of the ceramic oven is in use, the lower cover adjusting block 13 is L-shaped, and the bolt 15 passes through it, which satisfies the fixation between the lower cover adjusting block 13 and the lower cover 1 of the hinge, and also satisfies the fixation between the lower cover adjusting block 13 and the oven body. Then, the opening and closing shaft 3 and the bearing 4 satisfy the opening and closing between the upper cover 2 and the lower cover 1 of the hinge, and also satisfy the opening and closing between the oven door and the oven body. Then, the lubricating oil is delivered to the connecting pipe 1602 through the oil nozzle 1601, and then delivered to the inner ring of the bearing 4 through the connecting pipe 1602. Then, it is delivered to the inner ring of the bearing 4 through the first through hole 1603, and then to the inner ring of the bearing 4 and the contact surface between the inner ring of the bearing 4 and the opening and closing shaft 3 through the second through hole 1604, which satisfies the requirement of the bearing 4 and the inner ring of the bearing 4 in contact with the opening and closing shaft 3. The contact surfaces of the shaft 3 are lubricated, reducing the coefficient of friction and preventing jamming and unevenness during prolonged use, which could damage the product and affect the user experience. This improves the overall performance and user experience of the product and reduces maintenance costs. Next, the spring assembly 10, made of cobalt-based alloy, possesses high-temperature stability, corrosion resistance, and fatigue resistance, meeting the requirements for continuous operation in high-temperature environments. This prevents the spring assembly 10 from being corroded by corrosive substances and ensures that its elasticity is maintained during use, thereby improving the durability of the spring assembly 10. Finally, the protective coating 17 with ceramic coating provides it with extremely high hardness, high-temperature resistance, and a certain degree of corrosion resistance, preventing deformation or damage during daily use and thus improving the durability and reliability of the equipment.
