Description

Technical Field

[0001] This application relates to the field of experimental equipment, and in particular to a high-temperature thermal stability testing furnace. Background Technology

[0002] A high-temperature thermal stability testing furnace is an experimental device widely used in materials science, metallurgy, electronics, ceramics, and aerospace fields. It is primarily used to test and analyze the thermal stability, heat resistance, oxidation behavior, and thermal expansion characteristics of materials under high-temperature conditions. Its working principle typically involves heating the furnace cavity to a set temperature using heating elements, and then subjecting samples placed inside the furnace to long-term or short-term thermal exposure tests under constant temperature conditions. A high-temperature thermal stability testing furnace generally consists of a furnace body, heating elements, an insulation layer, a control system, and an outer shell.

[0003] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: During the operation of the test furnace, some areas of the outer shell may reach high temperatures due to heat conduction, especially at the joint between the furnace door and the furnace body. When loading samples, observing the test status, or performing maintenance, operators may accidentally come into contact with the high-temperature parts, resulting in serious burns. Therefore, improvements are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a high-temperature thermal stability testing furnace, aiming to solve the aforementioned problems.

[0005] A high-temperature thermal stability testing furnace includes a furnace body and a furnace door hinged to the furnace body. A base is installed below the furnace body, a connecting strip is installed on the upper surface of the base, a protective strip is connected to the connecting strip, a protective groove is provided on the base for the anti-slip strip to be inserted, a support groove is provided on the upper surface of the base, a support rod is rotatably connected in the support groove, and a limiting groove is provided on the lower surface of the connecting strip for the support rod to be inserted.

[0006] By adopting the above technical solution, when the furnace body starts to run, the connecting strip is pulled up, and the connecting strip drives the protective strip to move up, so that the support rod is rotated out of the support groove and locked into the limiting groove, thereby blocking the outside of the furnace door, avoiding accidental contact by test personnel, and reducing the occurrence of personnel injuries.

[0007] Optionally, a fixing magnet is connected to the connecting strip, and a metal block for the fixing magnet to be attracted is embedded in the base.

[0008] By adopting the above technical solution, the fixed magnet on the connecting strip is attracted to the metal block, thereby improving the connection strength of the connecting strip.

[0009] Optionally, one end of the support rod is connected to a resilient fastening block, which abuts against the bottom wall of the limiting groove.

[0010] By adopting the above technical solution, when the support rod is inserted into the limiting groove, the fastening block can press against the bottom wall of the limiting groove, thereby improving the installation firmness of the support rod and preventing the support rod from accidentally falling out of the limiting groove.

[0011] Optionally, a clearance groove is provided on the bottom wall of the support groove, a drive plate is provided in the clearance groove, and a drive spring is connected between the drive plate and the bottom wall of the clearance groove.

[0012] By adopting the above technical solution, the drive plate can quickly push the support rod out of the support groove under the action of the drive spring, thereby facilitating the improvement of the installation efficiency of the support rod.

[0013] Optionally, the lower end face of the base is connected to several casters.

[0014] By adopting the above technical solution, testers can quickly move the base using the casters, thereby quickly adjusting the position of the test furnace according to the test needs, saving time and effort.

[0015] Optionally, the base is threaded with at least two fixing screws along the vertical direction, and the lower end of each fixing screw is rotatably connected to a fixing suction cup.

[0016] By adopting the above technical solution, when it is necessary to restrict the movement of the base, the fixing screw is rotated so that the fixing screw presses the fixing suction cup tightly, and the fixing suction cup is attached to the external tabletop, thus restricting the movement of the base.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. When the furnace body starts running, pull the connecting strip up. The connecting strip will move the protective strip up, and the support rod will rotate out of the support groove and be inserted into the limiting groove, thereby blocking the outside of the furnace door to prevent test personnel from accidentally touching it and reduce the occurrence of personnel injuries.

[0019] 2. After the support rod is inserted into the limiting groove, the fastening block can press against the bottom wall of the limiting groove, thereby improving the installation stability of the support rod and preventing the support rod from accidentally falling out of the limiting groove.

[0020] 3. The test personnel can quickly move the base using the casters, thereby quickly adjusting the position of the test furnace according to the test needs, saving time and effort.

[0021] 4. When it is necessary to restrict the movement of the base, rotate the fixing screw to press the fixing screw into the fixing suction cup, so that the fixing suction cup is attached to the external tabletop, thus restricting the movement of the base. Attached Figure Description

[0030] This application discloses a high-temperature thermal stability testing furnace. (Refer to...) Figure 1 and Figure 2 It includes the furnace body 1 and the furnace door 2 hinged to the furnace body 1.

[0031] Reference Figure 2 , Figure 3 and Figure 4A base 3 is installed below the furnace body 1. A connecting strip 4 is installed on the upper surface of the base 3, and a protective strip 5 is fixedly connected to the lower surface of the connecting strip 4. A protective groove is provided on the base 3 for the anti-slip strip to be inserted. A fixing magnet 42 is fixedly connected to the connecting strip 4. A metal block 32, which is made of iron, is embedded in the base 3 for the fixing magnet 42 to be attracted. A support groove 31 is provided on the upper surface of the base 3. A support rod 6 is rotatably connected in the support groove 31. A limiting groove 41 is provided on the lower surface of the connecting strip 4 for the support rod 6 to be inserted. One end of the support rod 6 is connected to a flexible fastening block 61, which is made of fluororubber and abuts against the bottom wall of the limiting groove 41. When the furnace body 1 starts operating, pulling up the connecting strip 4 causes the protective strip 5 to move upward, rotating the support rod 6 out of the support groove 31 and locking it into the limiting groove 41, thereby blocking the outside of the furnace door 2 to prevent accidental contact by test personnel and reduce the risk of injury. The fixing magnet 42 on the connecting strip 4 is attracted to the metal block 32, thereby improving the connection firmness of the connecting strip 4. After the support rod 6 is locked into the limiting groove 41, the fastening block 61 can press against the bottom wall of the limiting groove 41, thereby improving the installation firmness of the support rod 6 and preventing the support rod 6 from accidentally falling out of the limiting groove 41.

[0032] Reference Figure 2 and Figure 3 A clearance groove 33 is provided on the bottom wall of the support groove 31. A drive plate 34 is installed in the clearance groove 33. A drive spring 35 is fixedly connected between the drive plate 34 and the bottom wall of the clearance groove 33. The drive spring 35 presses against the support rod 6. Under the action of the drive spring 35, the drive plate 34 can quickly push the support rod 6 out of the support groove 31, thereby improving the installation efficiency of the support rod 6.

[0033] Reference Figure 1 and Figure 2 The base 3 is equipped with casters 7 at the four corners of its lower end face. The test personnel can quickly move the base 3 using the casters 7, thereby quickly adjusting the position of the test furnace according to the test requirements, saving time and effort.

[0034] Reference Figure 1 and Figure 2 The base 3 has two fixing screws 8 connected vertically, and each fixing screw 8 has a fixing suction cup 81 rotatably connected to its lower end. When it is necessary to restrict the movement of the base 3, the fixing screws 8 are rotated so that they press the fixing suction cups 81 tightly, and the fixing suction cups 81 are attached to the external tabletop, thus restricting the movement of the base 3.

[0035] The implementation principle of a high-temperature thermal stability testing furnace in this application embodiment is as follows: when the furnace body 1 starts to run, the connecting strip 4 is pulled up, the connecting strip 4 drives the protective strip 5 to move up, and the support rod 6 is rotated out from the support groove 31 and locked into the limiting groove 41, thereby blocking the outside of the furnace door 2, avoiding accidental contact by the test personnel, and reducing the occurrence of personnel injury.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
