Description

Technical Field

[0001] This utility model relates to the field of high-temperature connection device technology, specifically a high-temperature connection device for an oven. Background Technology

[0002] In the high-temperature environment of an oven, a "temperature bursting element" typically refers to a safety protection device used to monitor or prevent overheating. Its core function is to trigger an alarm or cut off the heating system physically or electrically when the internal temperature of the oven exceeds a set safety threshold, thus preventing equipment damage or safety accidents.

[0003] The prior art patent document with publication number CN210218938U provides a high-temperature resistant connecting pipe, including an inner layer, an outer layer, and an intermediate layer disposed between the inner layer and the outer layer. The outer layer is provided with a plurality of outer ring grooves, and each outer ring groove is provided with a fixing ring. A fixing component is provided between the fixing ring and the outer ring groove. The fixing component includes a through hole disposed on the fixing ring, a bolt that penetrates the through hole and is detachably connected to the bottom of the groove, and a limiting ring groove disposed along the periphery of the through hole. This utility model is applicable to the field of connecting pipe technology.

[0004] Although the device has many beneficial effects, it still has the following problems: Although the heating system is cut off when the temperature of the pipe section is too high, it takes a long time for the pipe to cool down naturally, or the oven can be used for a short time due to the rapid temperature rise. The heat dissipation effect of the connecting pipe is poor. At the same time, when the connecting device is not in use and needs to be idle, the internal pipes are relatively fragile and may be damaged by foreign objects if left unused for a long time. The protection effect when idle is poor. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues, such as the poor heat dissipation of the connecting pipes when the temperature is too high (although the heating system is shut off, it takes a long time for the pipes to cool down naturally, or the oven's operating time is short due to the rapid temperature rise), and the poor protection effect of the connecting pipes when the device is not in use and needs to be idle, the internal pipes are relatively fragile and may be damaged by foreign objects if left unattended for a long time.

[0008] Therefore, the purpose of this utility model is to provide a high-temperature connecting device for an oven. A movable plate is fixedly connected to the sides of the first and second connecting flanges. A heat-absorbing copper ring is provided on the outer circumference of the movable plate. Simultaneously, the heat-absorbing copper ring, together with a fixed ring and a protective ring on its inner circumference, forms a movable groove. This allows the protective plate with a limit ring to freely stretch and move, preventing pipe jamming and allowing the heat emitted by the connecting device to be absorbed by the heat-absorbing copper ring, extending the service life of the connecting device or accelerating the cooling time after the heating system is cut off, resulting in better heat dissipation. Furthermore, an installation groove is provided on the inner circumference of the first and second connecting flanges of the connecting device. A filter screen is fixedly connected inside the installation groove, and a cover plate is connected to the outer circumference via a rotating shaft block. This allows the cover plate to be closed when the device is not in use to prevent damage from foreign objects entering the connecting device. During use, the filter plate also prevents foreign objects or dust from entering the connecting device, providing good internal protection.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural schematic diagram of an embodiment of a high-temperature connection device for an oven, including:

[0034] Please see Figures 1-4 This embodiment of a high-temperature connection device for an oven includes an outer flexible hose 5. A heat-absorbing copper ring 18 is provided on the surface of the outer flexible hose 5. A fixing ring 19 is welded to the outer circumference of the heat-absorbing copper ring 18. A protective ring 20 is welded to the outer circumference of the fixing ring 19. A movable groove 16 is formed inside the protective ring 20 and the heat-absorbing copper ring 18. A movable plate 15 is slidably connected inside the movable groove 16. A limit ring 17 is welded to the outer circumference of the movable plate 15. A first connecting flange 1 and a second connecting flange 2 are bonded and fixed to both sides of the outer flexible hose 5. A heat dissipation hole 21 is formed inside the outer surface of the protective ring 20.

[0035] It is worth noting that, in order to protect the internal explosion temperature tube 4 of the connecting device during operation and idle time, specifically, the first connecting flange 1 and the second connecting flange 2 are provided with mounting grooves 11 inside, and a filter screen 12 is welded inside the mounting grooves 11. A rotating shaft block 7 is welded to the outer circumference of the first connecting flange 1 and the second connecting flange 2. The two sides of the rotating shaft block 7 are connected to the cover plate 8 through the rotating shaft. The outer circumference of the cover plate 8 is glued and fixed with a buckle 9. The surface of the buckle 9 is magnetically connected with a locking buckle 10. The back of the locking buckle 10 is glued and fixed to the first connecting flange 1 and the second connecting flange 2.

[0036] Next, to facilitate the positioning and connection of the first connecting flange 1 and the second connecting flange 2, specifically, the first connecting flange 1 and the second connecting flange 2 are welded to both sides of the movable plate 15, and connecting rings 6 are welded to the sides of the first connecting flange 1 and the second connecting flange 2.

[0037] Meanwhile, to ensure the normal operation of the internal explosion temperature tube 4, the internal explosion temperature tube 4 is specifically bonded and fixed inside the outer flexible hose 5, and the first connecting flange 1 and the second connecting flange 2 are provided on both sides of the internal explosion temperature tube 4.

[0038] Furthermore, in order to install the connecting device on the side wall of the oven, specifically, the first connecting flange 1 and the second connecting flange 2 are provided with mounting holes 3 inside, and the mounting holes 3 are distributed in a ring at equal intervals inside the first connecting flange 1 and the second connecting flange 2.

[0039] It is worth noting that, in order to allow the outer flexible tube 5 to retract, specifically, connecting rings 6 are bonded and fixed to both sides of the implosion temperature tube 4, and the outer flexible tube 5 is bonded and fixed to the outer circumference of the connecting rings 6.

[0040] Finally, to protect the cover plate 8 of the connecting device, specifically, an external frame 13 is welded to the front of the cover plate 8, and a protective bracket 14 is welded inside the external frame 13. The external frame 13 is specifically a circular steel frame. When subjected to impact, the steel structure disperses the impact force around the frame, thereby achieving an impact resistance effect. The protective bracket 14 is a frame that needs to be installed inside the external frame 13 and used in conjunction with the external frame 13. Through the cooperation between the frame rod of the protective bracket 14 and the external frame 13, and with the external frame 13 having more directions to disperse the impact force, the impact resistance of the external frame 13 is further enhanced.

[0041] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0042] Combination Figures 1-4 The specific usage process of the high-temperature connection device for an oven according to this embodiment is as follows:

[0043] 1: When using this type of high-temperature oven connection device, the connection device first needs to be installed on the side wall of the oven. First, pull the cover plate 8 to separate the buckle 9 from the lock 10. Then, align the first connecting flange 1 or the second connecting flange 2 of the connection device with the mounting hole 3 on the side wall of the oven. After alignment, drive the bolt into the first connecting flange 1 or the second connecting flange 2, thereby installing the connection device on the side wall of the oven.

[0044] 2. After installation, the oven can be used immediately. During operation, the oven will generate high temperatures, which will be transferred through the internal explosion temperature tube 4. As the temperature of the internal explosion temperature tube 4 rises, the heat-absorbing copper ring 18 on the outer circumference of the outer hose 5 can continuously absorb the heat emitted by the internal explosion temperature tube 4 and the outer hose 5, thereby extending the oven's operating time. After prolonged use, when the internal temperature of the oven reaches a certain level, the internal explosion temperature tube 4 will cut off the heating system. The internal explosion temperature tube 4 is usually used to trigger safety protection when the temperature or pressure rises abnormally, and cuts off the heating system through mechanical or electrical linkage. After the heating system is cut off, since the heating system no longer generates heat, heat can be continuously dissipated through the heat dissipation holes 21 inside the protection ring 20, which accelerates the rate at which the heat-absorbing copper ring 18 absorbs and dissipates heat, thereby reducing downtime and increasing production efficiency. At the same time, the movable plate 15 will extend and retract synchronously along the groove when the outer hose 5 retracts, thereby preventing the connection device from jamming. The movable plate 15 can also be made of a material with good heat absorption, such as aluminum plate.

[0045] 3: Simultaneously, when the device is in use, the filter screen 12 is fixed inside the first connecting flange 1 and the second connecting flange 2 through the mounting groove 11. When the oven is running, the filter screen 12 can intercept impurities, dust or foreign objects, preventing foreign objects from entering the internal explosion temperature tube 4 and causing damage to the internal explosion temperature tube 4. At the same time, when the connecting device is not used for a long time and needs to be idle, the connecting device can be removed from the oven, and the cover plate 8 can be closed by the locking buckle 10 and the snap buckle 9, thereby preventing foreign objects from entering the internal explosion temperature tube 4 when the connecting device is idle and causing damage to the internal explosion temperature tube 4. At the same time, the top of the cover plate 8 is also fixedly connected to the external frame 13 and the protective bracket 14, thereby protecting the cover plate 8 and preventing the cover plate 8 from being deformed or damaged.

[0046] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
