Abstract
Description
Technical Field
[0001] This utility model relates to the field of oven technology, specifically to a high-temperature oven using copper alloy tubes. Background Technology
[0002] Copper alloy pipes are tubular materials composed of copper and other elements (such as aluminum, nickel, zinc, etc.). They belong to a type of non-ferrous metal pipe and are usually drawn seamless pipes. An oven is a device or appliance used for baking food. It typically uses a heat source (such as electricity, gas, or charcoal) to generate heat and transfers the heat to the food through radiation, convection, or conduction to achieve the purpose of cooking, drying, or heating. By placing copper alloy pipes in an oven for baking, the strength of the pipes can be improved, and the service life of the pipes can be extended.
[0003] For example, in an oven with Chinese patent publication number CN220124505U, the second protrusion disengages from the locking groove, the first protrusion slides to the second end of the mounting groove, and the second end of the mounting groove extends in the direction toward the locking groove. At this time, the side table is in a folded position, reducing the space occupied by the oven when it is not in use.
[0004] The oven described in the aforementioned patent can only reduce the space occupied during use. However, in existing ovens, the high internal temperature causes heat to be transferred to the oven surface, which can cause burns if people accidentally touch it. Therefore, an improved device is needed to address this problem. Utility Model Content

Detailed Implementation
[0019] 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.
[0020] Please see Figure 1-4 This utility model provides an embodiment of a high-temperature oven for producing copper alloy tubes, comprising a support device 3, with positioning devices 2 fixedly installed at the top of both ends of the support device 3, and a covering device 1 slidably sleeved on the top of the support device 3. The covering device 1 includes an arc-shaped cover plate 4, a locking key 5, and a side rail 6. The locking key 5 is symmetrically fixedly installed inside the top of the arc-shaped cover plate 4, and the side rail 6 is fixedly installed on the side end of the arc-shaped cover plate 4. The positioning device 2 includes a return spring 7, a displacement support rod 8, a pull rod 9, a support cavity 10, and a limit key 11. The return spring 7 is symmetrically fixedly installed inside the bottom of the support cavity 10. The displacement support rod 8 slides through the top of the support cavity 10 and connects to the top of the return spring 7. The limit key 11 is symmetrically fixedly installed on the top of the displacement support rod 8. The pull rod 9 slides through the bottom of the support cavity 10 and connects to the center of the bottom of the displacement support rod 8.
[0021] The support device 3 includes a support frame 12, a furnace cover 13, a chassis 14, support feet 15, and a handle 16. The furnace cover 13 is rotatably hinged to the top rear end of the chassis 14. The handle 16 is fixedly installed at the front end of the furnace cover 13. The support frame 12 is symmetrically fixedly installed at the top of the furnace cover 13. The support feet 15 are fixedly installed at both ends of the chassis 14. Ventilation holes are provided at both ends of the furnace cover 13 to facilitate the exhaust of flue gas.
[0022] The support cavity 10 is fixedly installed at the top of both ends of the furnace cover 13, and the key 5 is slidably inserted into the top of the support frame 12, which can support the arc cover plate 4 to slide in a straight line.
[0023] The top of the support frame 12 has a slot for inserting the key 5 into the top of the support frame 12.
[0024] The top of the limit key 11 is horizontally aligned with the top of the support frame 12. When the limit key 11 moves upward to the limit position, it can close the side of the support frame 12 near the support foot 15.
[0025] The rounded cover plate 4, the key 5, and the side rail frame 6 are all made of solid wood to reduce the efficiency of heat transfer.
[0026] Working principle: During use, the copper alloy pipe can be placed on the mesh frame on the chassis 14 for heating, allowing the copper alloy pipe to be fired. Subsequently, when the furnace cover 13 and the chassis 14 are in working condition, the internal temperature will be transferred to the surface of the furnace cover 13. At this time, the arc-shaped cover plate 4 can be moved onto the furnace cover 13. When the locking key 5 enters from the inlet of the support frame 12, it can press the limiting key 11 to move downward. The limiting key 11 is set at a 45° angle near the top of the side end of the support foot 15, which improves the smoothness of the locking key 5 passing through the limiting key 11. Furthermore, when the locking key... When the limit key 11 is pressed, the limit key 11 and the displacement support rod 8 can be pressed to move downwards. Then, when the locking key 5 slides into the slot inside the top of the support frame 12, it can support the arc cover plate 4 to slide in a straight line on the furnace cover 13. Then, the arc cover plate 4 has a groove that matches the handle 16 at the end opposite to the side rail frame 6, so that the two arc cover plates 4 can fit together. When the two arc cover plates 4 fit together, the end of the locking key 5 near the side rail frame 6 can be moved to be flush with the surface of the end of the support frame 12 near the support foot 15. At this time, the limit key... 11 will disengage from the locking key 5. The elasticity of the return spring 7 will cause the limiting key 11 to return upwards, allowing it to contact the surface of the locking key 5 near the side rail 6. This prevents the locking key 5 from falling out of the support frame 12. Since both the locking key 5 and the arc-shaped cover plate 4 are made of solid wood, heat transfer from the furnace lid 13 to the arc-shaped cover plate 4 is prevented, thus protecting the furnace lid 13. Subsequently, when the arc-shaped cover plate 4 needs to be removed, the pull rod 9 can be pulled downwards, allowing the limiting key 11 to move below the locking key 5. Then, the arc-shaped cover plate can be removed. 4. Pull outwards to remove the arc-shaped cover plate 4 from the furnace cover 13. When in use, the arc-shaped cover plate 4 is located on the outer ring of the furnace cover 13, which can prevent personnel from touching the furnace cover 13. At the same time, the fact that both the arc-shaped cover plate 4 and the locking key 5 are made of solid wood can reduce the heat transfer to the locking key 5 and the arc-shaped cover plate 4, thus preventing personnel from accidentally touching the furnace cover 13 and protecting the furnace cover 13. Meanwhile, the locking key 5 is T-shaped and slides in the slot inside the top of the support frame 12, which can prevent the arc-shaped cover plate 4 from falling off, thus completing the work.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
