[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2 An embodiment of the utility model is: a double-layer water-cooled high and low temperature test box, including a bottom plate 1, a box body 2 is fixedly connected to the top of the bottom plate 1, a heater 3 is arranged at the rear end of the box body 2, a water cooler 4 is arranged at the rear end of the box body 2, an experimental chamber 5 is opened on the inner wall of the box body 2, and an experimental chamber 2 6 is opened on the inner wall of the box body 2 below the experimental chamber 1 5, the temperature inside the experimental chamber 1 5 and the experimental chamber 2 6 is adjusted by the heater 3 and the water cooler 4, a placement plate 7 is slidably connected to the inner wall of the experimental chamber 1 5, the number of the placement plates 7 is set to two, and the other placement plate 7 is slidably connected to the inner wall of the experimental chamber 2 6, and the setting of the two placement plates 7 ensures that the objects inside the experimental chamber 1 5 and the experimental chamber 2 6 can be well placed.

[0032] Reference Figure 2 - Figure 4A clamping mechanism 8 is arranged above the placement plate 7, and four groups of clamping mechanisms 8 are arranged on each placement plate 7, and the four groups of clamping mechanisms 8 are respectively arranged at the four corners of the placement plate 7. By setting the number of clamping mechanisms 8, it is ensured that objects with lighter weight can be clamped at multiple angles to ensure the fixing effect. The clamping mechanism 8 includes a screw rod 81 and a slide rod 82. The bottom end of the screw rod 81 is rotatably connected to the top end of the placement plate 7, and the bottom end of the slide rod 82 is fixedly connected to the top end of the placement plate 7. The outer wall of the slide rod 82 is penetrated and slidably connected with a connecting ring 83. The shape of the connecting ring 83 is approximately that of two circular rings connected. A limiting groove 84 is opened on the surface of the connecting ring 83. The limiting groove 84 is opened in the area where the connecting ring 83 is outside the screw rod 81, and the shape of the limiting groove 84 is a shape formed by connecting a circular groove at the top and multiple vertical grooves at the bottom.

[0033] Reference Figure 2 - Figure 4 The outer wall of the sliding rod 82 above the connecting ring 83 passes through and is slidably connected with a block 85, the inner wall of the block 85 passes through and is threadedly connected to the outer wall of the screw rod 81, and the block 85 is provided with a tooth that fits with the limiting groove 84 in the area above the limiting groove 84. The bottom end of the block 85 is elastically connected to the top of the connecting ring 83 through a spring 86, one end of the spring 86 is fixedly connected to the bottom end of the block 85, and the other end of the spring 86 is fixedly connected to the top of the connecting ring 83. A moving rod 87 is provided inside the limiting groove 84, and the length of the moving rod 87 is consistent with the depth of the limiting groove 84, and the number of vertical grooves at the bottom end of the limiting groove 84 is a positive integer multiple of the moving rod 87. By setting the multiple, it is ensured that when the moving rod 87 moves to different positions, all the moving rods 87 have a matching limiting groove 84.

[0034] Reference Figure 2 - Figure 4 The end of the moving rod 87 away from the connecting ring 83 is fixedly connected to a swivel 88, and the shape of the swivel 88 is annular. The outer wall of the swivel 88 is fixedly connected to a swivel rod 89. An extension component 9 is arranged inside the swivel rod 89. The extension component 9 includes a sliding rod 91, and the sliding rod 91 is slidably connected to the inner wall of the swivel rod 89. A slot 92 is provided at the top of the sliding rod 91. The shape of the slot 92 is a tooth shape composed of a plurality of triangles. The shape of the bottom end of the positioning block 93 matches the shape of the slot 92. The matching shape setting ensures that when the positioning block 93 moves downward, the sliding rod 91 cannot move. The extension component 9 also includes a positioning block 93, and the top of the positioning block 93 is rotatably connected to a threaded rod 94, which passes through and is threadedly connected to the top of the swivel rod 89.

[0035] Working principle: When in use, the staff first opens the door of the box 2, and then pulls out the placement plate 7. When a light object needs to be fixed, the staff first places the object on the top of the placement plate 7, and then observes whether the edge of the object can directly contact the edge of the rotating rod 89.

[0036] When the length of the rotating rod 89 is not enough, the staff first pulls the sliding rod 91 outward. When the sliding rod 91 is pulled out to the appropriate position, the staff rotates the threaded rod 94 to increase the area of ​​the threaded rod 94 that enters the interior of the sliding rod 91, thereby allowing the threaded rod 94 to drive the positioning block 93 to move downward, so that the locking teeth at the lower end of the positioning block 93 enter the locking groove 92, thereby ensuring that the sliding rod 91 does not move during use.

[0037] When the length adjustment of the sliding rod 91 is completed, the staff first moves the swivel 88 upward so that the moving rod 87 is located in the circular ring area above the limiting groove 84. At this time, the staff can rotate the swivel 88 normally. When the swivel 88 is rotated to the appropriate position, the staff puts the moving rod 87 into the appropriate area below the limiting groove 84. At this time, since the moving rod 87 cannot move horizontally, the swivel 88 cannot rotate.

[0038] At this time, the staff rotates the screw rod 81 so that the screw rod 81 drives the block 85 to move downward. When the sliding rod 91 is not in contact with the object, the block 85 moves downward, driving the spring 86 to move downward, thereby driving the connecting ring 83 to move downward through the elastic force of the spring 86. At the same time, the rotating ring 88 and the moving rod 87 move downward under the action of gravity. When the sliding rod 91 contacts the object, the connecting ring 83 cannot continue to move downward, so only the block 85 moves downward at this time, and the spring 86 contracts.

[0039] When the block 85 moves downward alone, the teeth below the block 85 enter the area below the limiting groove 84. Therefore, the upper area of ​​the moving rod 87 is occupied by the block 85 at this time. Therefore, the swivel 88 cannot rotate during the experiment, so a better fixing effect can be achieved for lighter objects.

[0040] When the experimental object does not need to be fixed, the rotating rod 89 only needs to be rotated to a horizontal position and fixed, so as to prevent the rotating rod 89 from contacting the object and not affecting the object experiment.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
