[0024] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless there is a conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: Figures 1-4 As shown, the utility model provides a multi-axis turntable high and low temperature test box, including a lifting mechanism 2, and a rotating mechanism 1 is fixedly installed on the top of the lifting mechanism 2;

[0027] The rotating mechanism 1 includes two fixed blocks 101 and two bar blocks 102. A crossbar 103 is fixedly installed between the opposite sides of the outer walls of the two fixed blocks 101. The outer wall of the crossbar 103 is movably sleeved with two first rotating blocks 104. The tops of the two first rotating blocks 104 are fixedly installed with electric push rods 105. The output ends of the two electric push rods 105 are fixedly installed with second rotating blocks 106. A rotating rod 107 is fixedly installed between the opposite sides of the outer walls of the two bar blocks 102. The outer wall of the rotating rod 107 is movably sleeved with a placement plate 108. The bottom of the placement plate 108 is fixedly installed with two concave blocks 109. , and the outer walls of the two second rotating blocks 106 are rotatably connected to the inner walls of the two concave blocks 109, a fixed plate 110 is fixedly installed on the top of the placement plate 108, and two electric telescopic rods 111 are fixedly installed on one side of the outer wall of the fixed plate 110, and a splint 112 is fixedly installed between the output ends of the two electric telescopic rods 111, and two limiting grooves 113 are provided on the top of the placement plate 108, and the inner walls of the two limiting grooves 113 are movably embedded with sliding blocks 114, and the tops of the two sliding blocks 114 are fixedly connected to the bottom of the splint 112, and a strip plate 115 is fixedly installed on the top of the placement plate 108.

[0028] The effect achieved by the entire embodiment 1 is as follows: the product to be tested is placed on the placement plate 108 and close to the strip plate 115, and then the two electric telescopic rods 111 are started. Since the two sliding blocks 114 installed at the bottom of the clamping plate 112 are movably embedded in the two limiting grooves 113, the clamping plate 112 is stably moved to one side and the product is limited between the strip plate 115 and the clamping plate 112. Then, the electric push rods 105 installed on the two first rotating blocks 104 are started, so that the two second rotating blocks 106 are driven to rotate inside the two concave blocks 109. Since the two concave blocks 109 are installed on the placement plate 108, the two second rotating blocks 106 are driven to rotate inside the two concave blocks 109. The bottom of the placement plate 108 is placed, and the placement plate 108 is movably mounted on the rotating rod 107 installed between the two bar blocks 102, and then the two first rotating blocks 104 are also movably mounted on the cross bar 103 installed between the two fixed blocks 101, so that the placement plate 108 can be driven to rotate on the rotating rod 107 through the extension and contraction of the two electric push rods 105, so that the product limited on the placement plate 108 can be rotated at various angles, so that the product can be subjected to high and low temperature simulation experiments during the rotation process, which improves the diversity of test tests and has high practicality, thereby improving the test accuracy of the high and low temperature test.

[0029] Example 2: Figure 2-Figure 4 As shown, the lifting mechanism 2 includes a test box body 201, a heater 202 is provided on the top of the test box body 201, a refrigerator 203 is provided on the top of the test box body 201, two rectangular plates 204 are fixedly installed on the inner surface wall of the test box body 201, and a forward and reverse motor 205 is fixedly installed on the top of the two rectangular plates 204. A threaded rod 206 is fixedly installed on the top of the two forward and reverse motors 205. A concave support plate 207 is threadedly connected between the outer walls of the two threaded rods 206. The inner surface wall of the test box body 201 is fixedly mounted on the inner surface wall of the test box body 201. Four strip grooves 208 are opened, and the inner walls of the four strip grooves 208 are movably embedded with strip sliders 209, and one side of the outer wall of the four strip sliders 209 is fixedly connected to the outer wall of the concave support plate 207. Two limit plates 210 are fixedly installed on the inner wall of the test box body 201, and a temperature sensor 211 is fixedly installed on one side of the inner wall of the test box body 201. The top of the concave support plate 207 is fixedly connected to the bottom of the two fixed blocks 101, and the top of the concave support plate 207 is fixedly connected to the bottom of the two strip blocks 102.

[0030] The effect achieved by the entire embodiment 2 is that the two forward and reverse motors 205 installed on the two rectangular plates 204 are started, so that they drive the two threaded rods 206 to rotate inside the two limit plates 210. Since the concave support plate 207 is threadedly connected to the two threaded rods 206, the four strip sliders 209 installed on both sides of the concave support plate 207 are movably embedded in the four strip grooves 208, so that the concave support plate 207 can move up and down stably on the two threaded rods 206, and then the corresponding gas is injected into the interior of the test box body 201 through the heater 202 or the refrigerator 203. Under the interaction between the temperature sensor 211 and the controller provided in the outside, it can be ensured that the interior of the test box body 201 is within the appropriate temperature range, and the product can be subjected to high and low temperature simulation experiments during the lifting process, further improving the test accuracy of the high and low temperature test.

[0031] Working principle: First, open the door of the test chamber, place the product to be tested on the placement plate 108 and against the strip plate 115, then start the two electric telescopic rods 111, and under the action of the two limiting grooves 113 and the two sliding blocks 114, drive the clamping plate 112 to move stably, and limit the product between the clamping plate 112 and the strip plate 115, then inject the corresponding gas into the test chamber body 201 through the heater 202 or the refrigerator 203, and under the interaction of the temperature sensor 211 and the controller provided in the outside, make the temperature inside the test chamber within the appropriate temperature range for the test, then start the two electric push rods 105, through the extension and contraction of the two electric push rods 105, make the two first rotating blocks 104 rotate on the cross bar 103, and then the two second rotating blocks 106 rotate in the two concave blocks 109 installed at the bottom of the placement plate 108, so that the product can be placed. The placing plate 108 can rotate on the rotating rod 107, thereby driving the multi-angle rotation of the product on the placing plate 108, and performing high and low temperature simulation experiments during the rotation process, thereby improving the accuracy of the test. Secondly, when the forward and reverse motors 205 installed on the two rectangular plates 204 are started, under the action of the four strip grooves 208 and the four strip sliders 209 and the two limit plates 210, the concave supporting plate 207 is driven to move up and down stably on the two threaded rods 206, and the product can also be subjected to high and low temperature tests during the lifting process, further improving the diversity and practicality of high and low temperature simulation experiments on the product. In general, through the action of the rotating mechanism 1 and the lifting mechanism 2, the product can be subjected to high and low temperature simulation experiments during the rotation and lifting process, which is highly practical, thereby improving the accuracy of the simulation experiment detection of the product by the multi-axis turntable high and low temperature test chamber.
