Description

Technical Field

[0001] The utility model relates to the technical field of test chamber devices, in particular to a high-temperature aging test chamber. Background Art

[0002] In many fields such as automobiles, aviation, electromechanical and scientific research, in order to ensure the working performance and service life of electrical and electronic products or components, high-temperature aging tests are often carried out on them to test and determine the parameters and performance in high-temperature environments. Therefore, high-temperature aging test chambers are used accordingly. However, for existing test chambers, due to structural and design limitations, when multiple components are placed in different positions in the test chamber, the heat differences of the multiple components are often large, resulting in inconsistent high-temperature aging tests on different components, and thus resulting in large differences in test results. This will undoubtedly bring difficulties to subsequent test statistics and analysis, and also greatly affect the performance of existing test chambers.

[0003] For example, a new type of high-temperature aging test box with the announcement number CN107999151A includes a bracket and a box body arranged on the bracket, a box door is provided on the front side wall of the box body, and a motor and a reducer connected to the output shaft end of the motor are respectively provided at the external bottom end of the box body. The output shaft of the reducer is vertically arranged upward and extends to the interior of the box body, and a horizontally arranged turntable is also provided at the top end of the output shaft of the reducer. At the same time, a plurality of universal ball bearings are provided at the bottom end of the turntable, and the universal ball bearings are tightly fitted to the bottom wall of the box body.

[0004] Through structural design, the above-mentioned device greatly reduces the thermal differences between multiple test components, thereby effectively improving its own performance. However, the design of the above-mentioned device makes it difficult to effectively observe the internal test components. In such tests, real-time observation of the objects is a very important step. In addition, the high temperature inside can easily increase the internal air pressure. In special circumstances, the air pressure needs to be effectively discharged to avoid explosions caused by high air pressure. Utility Model Content

[0005] The purpose of the present invention is to provide a high-temperature aging test chamber to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-temperature aging test chamber, comprising a test chamber body, a fixing bolt installed on the surface of the test chamber body, and a rotating shaft inserted inside the fixing bolt, and a closing cover assembled on the outside of the rotating shaft, a top cover plate assembled on the upper end of the test chamber body, and a fitting block mounted on the surface of the top cover plate, and a rotating machine mounted on the upper end of the fitting block, a driving power supply installed on the back side of the rotating machine, and a control panel assembled on the surface of the driving power supply.

[0007] Preferably, a transmission module is installed on the surface of the test box, a thermal resistor is installed inside the transmission module, and an air supply mechanism is installed outside the thermal resistor.

[0008] Preferably, a through opening is provided on the side surface of the test box, and a steel protective glass is inserted into the through opening.

[0009] Preferably, a handle is mounted on the surface of the closing cover, and an engaging ring is assembled at a corresponding position of the closing cover.

[0010] Preferably, a pressure relief pipe is installed on the bottom surface of the test box, and a plurality of inertial springs are inserted into the interior of the pressure relief pipe, and the inertial springs are connected to the bottom cover plate.

[0011] Preferably, a plurality of universal wheels are installed on the surface of the test box.

[0012] Preferably, the lower end of the rotating machine is connected to a temperature-resistant rotating shaft, and a carrier plate is assembled on the surface of the temperature-resistant rotating shaft, while an auxiliary bearing is installed on the upper end of the temperature-resistant rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Compared with other high-temperature aging test chambers, this device provides an observation position for test personnel by installing tempered glass on the side, and a rotating display plate is installed inside. Since the internal high temperature generates heat through resistance and releases it through the heat dissipation port, the installation of the rotating mechanism can keep the heating degree of most objects consistent.

[0015] 2. In addition, the device is equipped with an independent pressure relief pipe at the bottom of the box. When the internal air pressure is too high, it will push the inertial spring to move outward, pushing the bottom cover plate out of the gap to relieve pressure, so as to prevent the internal air pressure from exceeding the specified range. At the same time, universal wheels are installed on the outside of the device to provide good transportation effect for the device. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Figure 1 This is an oblique-angle side overview of the device. The main body is an experimental box 1. A fixing bolt 7 is installed on the surface of the experimental box, and a rotating shaft 6 is inserted inside the fixing bolt 7. One end of the fixing bolt 7 is assembled to the surface of the experimental box 1 by welding, and the rotating shaft 6 and the surface end cover are matched to provide it with a rotating effect on the fixing bolt 7. At the same time, a closing cover 8 is assembled on the outside of the rotating shaft 6. A top cover plate is assembled at the upper end of the experimental box, and a fitting block 5 is installed on the surface of the top cover plate. At the same time, a rotating machine 4 is installed at the upper end of the fitting block 5. A transmission shaft is inserted inside the rotating machine 4, and its transmission shaft is connected to the inside of the experimental box 1 to provide it with rotation ability. A driving power supply 3 is installed on the back side of the rotating machine 4, and a control panel is assembled on the surface of the driving power supply 3;

[0023] Figure 2 This is a small-angle bottom overview of the device. The main body is a test box. A transmission module 13 is installed on the surface of the test box, and a thermal resistor is installed inside the transmission module 13. At the same time, an air supply mechanism 16 is installed on the outside of the thermal resistor. The air supply mechanism 16 consists of a fan, which mainly transports the heat generated by the thermal resistor to the inside. The transmission modules 13 are respectively installed on the sides of the test box 1, of which the back is the main module, and the thermal resistor installed inside is the main resistor, providing the main heat energy for the interior. A through hole is provided on the side surface of the test box, and a steel protective glass is inserted on the through hole. The installation of transparent tempered glass 2 allows the experimenter to observe the changes in the required experimental object from the beginning to the end of heating. A handle is installed on the surface of the closing cover 8, and a meshing ring is assembled at the corresponding position of the closing cover 8. The meshing ring is designed along the edge of the closing cover 8 to ensure the airtightness of the internal space and prevent heat loss.

[0024] Figure 3This is a general view of the internal structure of the device. The main body is a test box. A pressure relief pipe 12 is installed on the bottom of the test box, and several inert springs 11 are inserted inside the pressure relief pipe 12. The inert spring 11 is a spring with greater resistance, and a smaller air pressure cannot move or push it open. At the same time, the inert spring 11 is connected to the bottom cover plate 10. The installation of the inert spring 11 allows the internal air pressure to reach a certain value, which will automatically push the inert spring 11 slightly open, releasing the internal air pressure to ensure that the internal air pressure is constant. Several universal wheels 9 are installed on the surface of the test box, and the lower end of the rotating machine 4 is connected to the temperature-resistant rotating shaft 14, and the surface of the temperature-resistant rotating shaft 14 is equipped with a carrier plate 15. At the same time, an auxiliary bearing 17 is installed at the upper end of the temperature-resistant rotating shaft 14, and a stabilizing seat is installed at the bottom of the rotating shaft. The stabilizing seat is used to ensure the stability of the device in the vertical direction. The auxiliary bearing 17 is welded to the lower surface of the top cover plate to provide the necessary support.

[0025] During actual use, first grasp the handle to open the closed cover 8, place the objects to be used for high-temperature aging test on the upper end of the carrier plate 15, then close the closed cover 8, turn on the driving power supply 3, and with the operation of the transmission module 13 and the rotating machine 4, the internal thermal resistor begins to generate heat, and the several air supply mechanisms 16 installed inside it transport the heat to the inside, and the rotating machine 4 drives the transmission shaft to rotate the internal shaft of the experimental box 1, and the carrier plate 15 rotates slowly, so that the objects placed on the upper end are heated evenly, and the experimenter observes the changes in the internal objects from the tempered glass 2 on both sides. As the temperature rises, the internal air pressure reaches the limit value at any time. At this time, the air pressure will push open the bottom cover plate 10 connected to the inertia spring 11 at the bottom to release the air pressure, ensuring that the internal air pressure is at a safe value.

[0026] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
