With the improvement of people's living standards, people's consumption of cars is increasing, and the market of auto parts is getting bigger and bigger. Before auto parts are put into mass production, they will be subjected to a large number of harsh environment simulation experiments. Among them, temperature experiment is an important experimental environment, which can simulate extreme high temperature and extreme low temperature, observe the state of parts under extreme temperature, and judge whether they meet the standards;
[0003] However, some inferior parts are prone to explosion and melting under extremely high temperature conditions.

[0013] A temperature test chamber also includes an experimental method, which includes the following steps:
[0014] Step 1: Make sure the temperature test chamber has been properly installed and powered on, check whether the test chamber is clean, whether the installation frame and its support wires are in good condition, prepare the parts to be tested, and ensure that they meet the test requirements;
[0015] Step 2: Open the box cover to expose the experimental chamber, and place the components on the support wires between the mounting frames to ensure that the components are stable and will not slip off the support wires;

Through the winding and releasing mechanism of the support wire, the test environment can be quickly cleaned and reset, thereby shortening the preparation time between two adjacent tests and greatly improving the test efficiency.
[0023] 2. The design of the support line allows the parts to be stably supported during the test. At the same time, when the parts melt or deform, the melted materials can pass through the support line smoothly, reducing the contamination of the test chamber and the impact on subsequent tests.
[0024] 3. After the test is completed, the mounting frame can be slid out of the experimental cavity, which is convenient for thorough cleaning and maintenance of the support wire. In addition, by rotating the rotating mechanism in the opposite direction, the support wire can be easily withdrawn from the second storage cavity and rewound back into the first storage cavity, further simplifying the cleaning process.
[0025] 4. The rotating mechanism realizes precise control of the second winding rod by means of helical tooth meshing. At the same time, the design of the limit plate and arc-shaped lock ensures the stability of the rotating rod during the rotation process, prevents accidental sliding or loosening, and improves the accuracy and reliability of the test.
[0026] 5. Since the support wire can remain straight and stably support the parts, it can reduce the test errors caused by shaking or instability of parts and improve the accuracy and reliability of the test results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0038] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0039] like Figure 1-8 As shown, a temperature test box of the present invention includes a body 1, an experimental chamber 11 is provided on the upper side of the body 1, a box cover 12 matching the experimental chamber 11 is provided on the front side of the body 1, a control panel 13 is provided on the right side of the body 1, a mounting frame 14 is slidably mounted in the experimental chamber 11, a first storage chamber 15 and a second storage chamber 16 are respectively provided on the front and rear sides of the mounting frame 14, a first winding rod 2 is rotatably mounted in the first storage chamber 15, a reset mechanism matching the first winding rod 2 is provided in the first storage chamber 15, a plurality of support wires 21 are wound and connected to the outer surface of the first winding rod 2, a plurality of first through holes 22 are provided on the outer surface of the first storage chamber 15, a second winding rod 23 is rotatably mounted in the second storage chamber 16, a plurality of second through holes 24 are provided on the outer surface of the second storage chamber 16, a plurality of support wires 21 pass through the plurality of first through holes 22 and the plurality of second through holes 24 in sequence to be connected to the second winding rod 23, and a rotating mechanism matching the second winding rod 23 is provided on the upper side of the mounting frame 14.
[0040] When it is necessary to conduct temperature tests on parts, the staff can open the box cover 12 to expose the experimental chamber 11, and then place the parts on the several support wires 21 between the installation frames 14. After closing the box cover 12, the control panel 13 is used to control the body 1 to start working, and the temperature in the experimental chamber 11 is changed to realize the testing of the parts. After the high-temperature test on the parts, if the parts melt, the melted materials can pass through the several support wires 21, and when the experiment is completed, the staff can remove the materials from the several support wires 21. At this time, the staff starts the rotating mechanism, and the rotating mechanism drives the second winding rod 23 to start rotating. During the rotation process, the second winding rod 23 simultaneously winds the several support wires 21, so that the several support wires 21 are pulled out of the first storage chamber 15 and stored in the second storage chamber 16. During the pulling process of the support wires 21, the first winding rod 2 is driven to rotate, thereby driving the reset mechanism to start contracting. The function of the reset mechanism is to keep the several support wires 21 in a straight state. When the part that carried the material last time After the support wire 21 is received in the second storage chamber 16, the staff can stop starting the rotating mechanism, stop rotating the second winding rod 23, and stop winding the support wire 21. At this time, the staff can immediately place new materials that need to be tested on the support wire 21, so that the material can be effectively put into the test process again, which can shorten the time of two adjacent component temperature tests and improve the test efficiency. When all experiments are completed, the staff can slide the installation frame 14 out of the test chamber 11. At this time, the staff can clean the support wire 21, and after the staff reversely rotates the rotating mechanism, the support wire 21 is reversely removed from the surface of the second winding rod 23 and withdrawn from the second storage chamber 16. At the same time, the reset mechanism begins to extend, driving the first winding rod 2 to start resetting and rotating, and winding the support wire 21 withdrawn from the second storage chamber 16, so that the support wire 21 can be gradually received in the first storage chamber 15 again. In the process of the support wire 21 gradually being received from the second storage chamber 15 into the first storage chamber 15, the staff can clean the surface of the support wire 21.
[0041] The reset mechanism includes cavities 3 arranged on the left and right inner walls of the first receiving chamber 15 , and the two ends of the first winding rod 2 extend into the two cavities 3 respectively. The two cavities 3 are both provided with first coil springs 31 connected to the first winding rod 2 .
[0042] When the support wire 21 is pulled out from the first storage chamber 15, the first winding rod 2 drives the first coil springs 31 on both sides to start to contract. Through the extension of the coil springs 31, the support wires 21 are kept in a straight state, so that the parts that need to be tested can be supported. When the support wire 21 is withdrawn from the second storage chamber 16, the coil spring 31 can be extended to drive the first winding rod 2 to return to rotation, so that the support wires 21 can be returned to the original state and wound.
[0043] The rotating mechanism includes a first bevel tooth 32 connected to the outer surface of the second winding rod 23, a rotating rod 33 is rotatably mounted on the inner wall of the upper side of the second storage chamber 16, a second bevel tooth 34 meshing with the first bevel tooth 32 is provided on the lower side of the rotating rod 33, a handle 35 is installed on the upper side of the rotating rod 33 through the mounting frame 14, an inner cavity 36 matching the position of the rotating rod 33 is provided in the mounting frame 14, the rotating rod 36 passes through the inner cavity 36, a limiting plate 37 is provided on the outer surface of the rotating rod 36, a plurality of arc grooves 38 are provided on the outer surface of the limiting plate 37, a telescopic rod 39 is provided on the inner wall of the inner cavity 36, a first spring 391 is sleeved on the outer surface of the telescopic rod 39, and an arc-shaped locking piece 392 matching the plurality of arc grooves 38 is provided on the end of the telescopic rod 39.
[0044] When the staff turns the handle 35, the rotating rod 33 can be driven to rotate. During the rotation of the rotating rod 33, the second bevel gear 34 can be driven to start rotating. Since the second bevel gear 34 is meshed with the first bevel gear 32, the first bevel gear 32 can be driven to rotate. The first bevel gear 32 drives the first winding rod 2 to rotate. With this design, the staff can drive the first winding rod 2 to rotate by turning the handle 35. When the staff rotates in two directions respectively, the first winding rod 2 can be driven to rotate in two directions respectively. In the process of rotating the rotating rod 36, the limiting plate 37 can be driven to rotate. Since the outer surface of the limiting plate 37 is provided with a plurality of arc grooves 38 , so the outer surface of the limit plate 37 continuously abuts against the arc-shaped locking piece 382. When the protruding portion contacts the arc-shaped locking piece 382, it pushes the arc-shaped locking piece 382 to start moving, driving the first spring 391 and the telescopic rod 39 to contract. When the arc-shaped groove 38 matches the position of the arc-shaped locking piece 382, the arc-shaped locking piece 382 can be driven to lock into the arc-shaped groove 38 under the action of the extension of the first spring 391. With this design, the staff can limit the limit plate 37 without turning the handle 35, thereby limiting the rotating rod 33. Therefore, the second winding rod 23 will not rotate easily, thereby effectively maintaining the supporting force for the material.
[0045] A plurality of connecting rods 4 are provided on the lower surface of the mounting frame 14 , and a plurality of connecting rods 4 are jointly equipped with an inclined plate 41 , baffles are provided on both sides of the inclined plate 41 , a connecting frame 42 is connected to the lower side of the inclined plate 41 , and a storage box 43 is buckled on the lower side of the connecting frame 42 .
[0046] When the material being tested melts under high temperature, the melted material passes through the support lines 21 and falls on the inclined plate 41. Under the guidance of the inclined plate 41, the melted material flows downward, passes through the connecting frame 42 and falls into the storage box 43. In this way, the melted material can be collected for centralized processing later.
[0047] The left and right sides of the mounting frame 14 are both provided with storage tubes 44 that match the position of the first storage chamber 15. Slide blocks 45 are slidably and sealably installed in the two storage tubes 44. A second spring 46 is provided on the lower side of the slide block 45. A slide rod 47 that slides into the first storage chamber 15 is fixedly connected to the upper side of the slide block 45. A pressure block 48 is provided on the upper side of the slide rod 47. A cam 49 that matches the pressure block 48 is provided on the outer surface of the first winding rod 2. Ventilation pipes 5 are provided on the lower sides of the two storage tubes 44. The two ventilation pipes 5 are connected together and are equipped with a distribution pipe 51. The distribution pipe 51 is installed on the upper side of the inclined plate 41. The distribution pipe 51 is equipped with a plurality of nozzles 52 pointing to the lower side of the inclined plate 41.
[0048] During the rotation of the first winding rod 2, the cams 47 on both sides are driven to start rotating. During the rotation of the cams 47, the cams 47 continuously press downward against the pressure block 48. When the pressure block 48 moves downward, the slider 45 is driven downward by the slide rod 47 to squeeze the air in the storage tube 44, and the gas is rushed into the distribution pipe 51 through the ventilation pipe 5, and then sprayed out through a number of nozzles 52, so as to improve the flow state of the material on the inclined plate 41 and facilitate the material to enter the storage box 43. When the cam 47 cancels the pressure on the pressure block 48, it drives the slider 45 to reset in the storage tube 44 under the action of the extension of the second spring 46.
[0049] Support bars 53 are provided on the inner walls of the left and right sides of the experimental chamber 11 , and slide grooves 54 are provided on the opposite sides of the two support bars 53 . Slide bars 55 matching the slide grooves 54 are provided on the left and right sides of the installation frame 14 .
[0050] The slide bar 55 slides in the slide groove 54 , so when the installation frame 14 slides, it drives the slide bar 55 to slide in the slide groove 54 .
[0051] A pulling handle 56 is provided on the front side of the installation frame 14. The design of the pulling handle 56 facilitates the staff to pull the installation frame 14.
[0052] A temperature test chamber also includes an experimental method, which includes the following steps:
[0053] Step 1: Ensure that the temperature test chamber has been properly installed and powered on, check whether the test chamber 11 is clean, whether the mounting frame 14 and its support wires 21 are in good condition, prepare the components to be tested, and ensure that they meet the test requirements;
[0054] Step 2: Open the box cover 12 to expose the experimental chamber 11, and place the components on the support wires 21 between the mounting frames 14 to ensure that the components are stable and will not slip off the support wires;
[0055] Step 3: Close the box cover 12 to ensure that the experimental chamber 11 is sealed, set the required temperature conditions and test time through the control panel 13, start the test program, and the test box will start working to adjust the temperature in the experimental chamber 11 to the set value;
[0056] Step 4: During the test, regularly observe the operating status of the test box and the reaction of the components. If necessary, the temperature can be adjusted or the test time can be extended or shortened through the control panel 13;
[0057] Step 5: When the test reaches the preset time or meets other end conditions, the test box will automatically stop working, wait for the temperature in the test chamber 11 to drop to a safe range, open the box cover 12 to take out the tested parts, and perform necessary inspections or measurements;
[0058] Step 6: If melted materials or other residues are generated during the test of the parts, they need to be removed from the support wire 21 and cleaned. The rotating mechanism is used to wind or unwind the support wire 21. First, the used support wire 21 is wound onto the second winding rod 23 through the rotating mechanism, and a new support wire 21 is pulled out from the first storage chamber 15. When the support wire 21 needs to be cleaned or replaced, the mounting frame 14 can be slid out of the experimental chamber 11, and the rotating mechanism is rotated in the opposite direction to remove the support wire 21 from the second winding rod 23. At the same time, the reset mechanism will automatically extend to help rewind the support wire 21 onto the first winding rod 2. Clean the surface of the support wire 21 to ensure that there is no residue or dirt.
[0059] Step 7: Record key data during the test, such as temperature changes, component reactions, etc., analyze the test data, and evaluate the performance changes of components under different temperature conditions.
