[0021] To make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, rather than all of the embodiments. The components of the embodiment of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiment of the present application. It should be noted that, in the absence of conflict, the various features in the embodiment of the present application can be combined with each other, and the combined embodiment is still within the protection scope of the present application.

[0022] Most of the existing thermocouple annealing cabinet wire suspension structures use platinum hooks, which mainly have the following problems: the platinum hook is in point contact with the annealed wire, and the contact area is small. When the oxide layer or impurities on the surface of the annealed wire are thick, it will cause a small current to fail to conduct. When the current continues to increase, it may cause the wire temperature to rise suddenly, which is easy to burn the annealed wire. To solve the above problems, the embodiment of the present application changes the point contact of the suspended wire to line contact.

[0023] like Figure 1As shown, the embodiment of the present application provides a thermocouple cleaning annealing cabinet suspension module, including: a mounting shaft 20 fixed on a mounting structure, an electrode 210 is formed at the bottom of the mounting shaft 20, the mounting shaft 20 is used to connect a power supply, a pure platinum sheet 30 is sleeved on the outer side of the electrode 210, and a clamping module is arranged at the end of the mounting shaft 20; the clamping module includes a pressing handle 50 and a spring 520 sleeved on the mounting shaft 20, the pressing handle 50 can move along the axis of the mounting shaft 20, the spring 520 is arranged inside the pressing handle 50, and the pressing handle 50 is close to the mounting structure. The end of the spring 520 is connected to the mounting shaft 20 and the clamping end, respectively, so as to press the clamping end against the pure platinum sheet 30; a corundum gasket 40 is also arranged between the clamping end and the pure platinum sheet 30, and the corundum gasket 40 is arranged close to the clamping end, and a corundum tube 220 is arranged on the surface of the mounting shaft 20 between the corundum gasket 40 and the pure platinum sheet 30, which is used to suspend the thermocouple wire on the outer peripheral side of the corundum tube 220.

[0024] The pressing handle 50 of the embodiment of the present application is an aluminum pressing handle 50, and the pure platinum sheet 30 is a 99.9% pure platinum sheet 30. When it is necessary to hang the even wire, the aluminum pressing handle 50 is pulled outward, and the even wire is hung between the corundum gasket 40 and the pure platinum sheet 30. After hanging, the aluminum pressing handle 50 is released, and the spring 520 inside the aluminum pressing handle 50 is used to press the even wire between the corundum gasket 40 and the pure platinum sheet 30. Figure 2 It is a schematic diagram of the structure of the corundum gasket 40 and the pure platinum sheet 30 being pressed tightly together. Figure 3 It is a schematic diagram of the structure in which the aluminum pressing handle 50 is pulled outward.

[0025] Specifically, the pressing handle 50 extends two oppositely arranged handles 510 in a direction perpendicular to the mounting axis 20, and the handle 510 forms a first pressing surface toward the mounting structure, and the pressing module further includes a button 60 near one end of the handle 510, and the surface of the button 60 forms a second pressing surface. To facilitate pulling up the aluminum pressing handle 50, the embodiment of the present application is provided with anti-slip textures on the second pressing surface.

[0026] like Figure 4 As shown, the diameter of the button 60 is larger than the diameter of the mounting shaft 20, so that it is sleeved on the end of the mounting shaft 20. One end of the button 60 is inserted into the pressing handle 50, and the button 60 is inserted into the shaft wall of the pressing handle 50 to form a step groove. The spring 520 rests on the step groove, and the button 60 and the mounting shaft 20 are fixed by a threaded connection.

[0027] Specifically, the mounting structure includes a ceramic insulating terminal 10, a mounting shaft 20 passing through the ceramic insulating terminal 10, and being threadedly connected to the electrode 210 through a connecting nut 240 and a connecting wire 230 on the side of the ceramic insulating terminal 10 away from the electrode 210, wherein the connecting nut 240 is threadedly mounted on the mounting shaft 20, and the connecting wire 230 is mounted on the outer peripheral side of the connecting nut 240, and the connecting wire 230 is used to energize the electrode 210.

[0029] Specifically, the surface of the aluminum pressing handle 50 is anodized to reduce its conductivity while making it beautiful and safe.

[0030] Thermocouple cleaning annealing cabinet hanging modules are arranged in pairs in the annealing cabinet.

[0031] The utility model changes the point contact of the even wire during suspension into line contact. When the even wire needs to be suspended, the aluminum pressure handle 50 is pulled outward, and the even wire is suspended between the corundum gasket 40 and the pure platinum sheet 30. After the suspension is completed, the aluminum pressure handle 50 is released, and the even wire is pressed between the corundum gasket 40 and the pure platinum sheet 30 by using the spring 520 inside the aluminum pressure handle 50. Compared with the traditional platinum hook, the contact area is larger and more stable. When the even wire expands during the heating process, the spring 520 will deform accordingly according to the expansion of the even wire, and will not damage the even wire due to the pressing. At the same time, the even wire is ensured to be in close contact with the pure platinum sheet 30. The electrode 210 adopts a brass gold-plated electrode 210, which has good conductivity and heat dissipation. At the same time, the gold plating treatment prolongs the service life of the brass electrode 210. The surface of the aluminum pressure handle 50 is anodized to reduce its conductivity, and it is beautiful and safe.

[0032] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
