Technical Field
[0001] The utility model relates to the technical field of heat preservation, in particular to a double-layer iron box with heat preservation function. Background Art
[0002] A tangential key is a mechanical connection device, usually used on rotating equipment or mechanical shafts. The main function of a tangential key is to transmit torque. A single-sided tangential key transmits unidirectional torque, while a double-sided tangential key transmits torque in both positive and negative directions. When assembling a tangential key, it needs to be cold-assembled, which requires a double-layer iron box. The double-layer iron box is a device specifically used to cool the tangential key.
[0003] Some existing double-layer iron boxes lack insulation cotton inside, which makes it difficult to keep the temperature inside the iron box low for a long time because there is no insulation cotton to insulate the tangential key when it is placed in the double-layer iron box, and it is difficult to prevent the slow evaporation of liquid nitrogen, resulting in the failure of cold installation of the tangential key. Therefore, those skilled in the art provide a double-layer iron box with insulation function to solve the problems raised in the above background technology. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a double-layer iron box with a heat preservation function. Heat preservation cotton is fixedly connected to the inside of the double-layer iron box, so that the inside of the iron box can be kept at a low temperature continuously under the action of the heat preservation cotton, and the evaporation of liquid nitrogen can be effectively slowed down, thereby facilitating the subsequent cold installation of the tangential key.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-layer iron box with heat preservation function, comprising an iron box module, a sealing cover module is magnetically arranged on the upper surface of the iron box module, a heat insulation layer is fixedly connected to the outer surface of the iron box module, the iron box module comprises an iron box body, and heat preservation cotton is fixedly connected to the bottom end and both sides of the iron box body;
[0006] Fixed blocks are fixedly connected to the surfaces of both sides of the inner wall of the iron box body, and sandwich panels are clamped on the upper surfaces of the multiple fixed blocks. The thermal insulation layer includes a base layer, and a vacuum layer is fixedly connected to the upper surface of the base layer. The upper surface of the vacuum layer is fixedly connected to the insulation layer, and the upper surface of the insulation layer is fixedly connected to the outer metal shell.
[0007] Through the above technical scheme, the tangential keys can be well insulated by the heat-insulating cotton inside the iron box body, and with the cooperation of the fixed plate and the sandwich plate, more tangential keys can be installed in the iron box to avoid wasting the space inside the iron box. Because the iron box is filled with liquid nitrogen, and the temperature of the liquid nitrogen is very low, because an insulation layer is fixedly connected to the surface of the iron box body, the liquid nitrogen can be kept in a low temperature state for a long time under the action of the insulation layer, so that the function of the liquid nitrogen will not disappear in a short time.
[0008] Furthermore, a scale groove is provided on the front end surface of the iron box body, and a magnetic attraction layer is fixedly connected to the upper end surface of the iron box body;
[0009] Through the above technical solution, the amount of liquid nitrogen inside the iron box can be observed under the action of the scale groove, and the iron box body and the sealing cover body can be conveniently fixed together by magnetic attraction under the action of the magnetic attraction layer.
[0010] Furthermore, a buoyancy ball is movably arranged on one side surface of the bottom end of the inner part of the iron box body, and two first grooves are arranged on the bottom end surface of the iron box body;
[0011] Through the above technical solution, the amount of liquid nitrogen contained in the iron box body can be understood under the action of the buoyancy ball. The main function of the first groove is to place the tangential key.
[0012] Furthermore, two second grooves are provided on the upper surface of the sandwich plate, and plug blocks are fixedly connected to both side surfaces of the lower end of the sandwich plate away from the center;
[0013] Through the above technical solution, the tangential key is placed under the action of the second groove, and the sandwich plate is fixed inside the iron box body under the action of the insert block.
[0014] Furthermore, the sealing cover module comprises a sealing cover body, and handles are fixedly connected to the front and rear surfaces of the upper end of the sealing cover body;
[0015] Through the above technical solution, the sealing cover body can be easily taken under the action of the handle, thereby avoiding the inconvenience of taking the sealing cover body due to the relatively heavy sealing cover body.
[0016] Furthermore, a liquid nitrogen replenishing pipeline is fixedly connected to a surface on one side of the upper end of the sealing cover body;
[0017] Through the above technical solution, liquid nitrogen can be replenished inside the iron box body through the action of the liquid nitrogen replenishment pipeline.
[0018] Furthermore, an exhaust pipe is fixedly connected to the other side surface of the upper end of the sealing cover body;
[0019] Through the above technical solution, the exhaust duct can effectively ensure that the internal air and the external atmosphere are connected to each other.
[0020] The utility model has the following beneficial effects:
[0021] 1. The utility model proposes a double-layer iron box with heat preservation function. Because the tangential key takes a long time to cool down and the temperature of liquid nitrogen is very low, the tangential key needs to be kept warm during the cooling process. By using heat preservation cotton to keep it warm, the liquid nitrogen can be kept at a low temperature in the iron box continuously, and the evaporation of liquid nitrogen can be slowed down. At the same time, the temperature of the tangential key inside the iron box can be prevented from changing under the action of the heat preservation cotton.
[0022] 2. The utility model proposes a double-layer iron box with heat preservation function. A heat-insulating layer is fixedly connected to the outer wall of the iron box body. The interaction between the vacuum layer and the outer metal shell can effectively prevent external heat from entering the interior of the iron box body. At the same time, the heat conduction and heat radiation can be further reduced under the action of the heat-insulating layer, so that when the staff needs to carry the iron box after wearing gloves, they will not be frozen because of the liquid nitrogen inside the iron box.
