[0006] As mentioned above, the outer wall at the top end of the measuring column is connected through one side of the bottom surface of the upper base, and the top of the outer wall of the measuring column is connected to one side of the inner part of the upper base in a sliding manner.

[0007] As mentioned above, a plurality of limit sliding bars are fixedly connected to both sides of the interior of the test frame, and the center of the outer wall of the limit sliding bar is slidably connected to the limit support.

[0008] As described above, the limit supports are respectively located on both sides of the outer wall of the upper base, and both sides inside the limit supports are slidably connected to the center of the outer wall of the limit slide rod. The center of the outer wall of the limit slide rod is connected through the inner side of the limit support, and the center of the outer wall of the limit slide rod is slidably connected to the inner side of the limit support.

[0009] As described above, limit slide frames are respectively fixedly connected to both sides of the top of the test frame, and the limit slide frames are located on both sides of the outer wall of the bidirectional lead screw. One end of the outer wall of the bidirectional lead screw is connected through the inner side of the inner wall of the test frame, and one end of the outer wall of the bidirectional lead screw is connected through and fixedly connected to the outer wall of the output end of the driving motor through the inner side of the inner wall of the test frame.

[0013] First, the present utility model sets limit supports on both sides of the upper base, and the limit slide rod passes through its interior to ensure that the upper base can only move vertically along the slide rod. The measuring column is placed on one side of the lower base and is slidably connected to the upper base. During the compression test, the upper base presses the ice pad along the slide rod, and the degree of extrusion is recorded by observing the bottom surface and the scale of the measuring column, thereby improving the accuracy and reliability of the test, ensuring the stability and accuracy of the vertical movement of the upper base during the subsequent test process of the device, avoiding measurement errors caused by tilting or offset, and further facilitating the subsequent compression detection of the ice pad by the driving motor for the device.

The limit carriage restricts the horizontal movement of the limit top plate. The bidirectional lead screw drives the limit top plate to move towards the center. The movable support rods between the upper movable support and the lower movable support are arranged crosswise and cooperate with the limit slide rod to push the upper base to press the ice pad. The pressure sensor and the measuring column jointly record the compression amount of the ice pad. Thus, through the close cooperation between the movable support rod and the limit slide rod, the compressive resistance test of the ice pad is realized, ensuring the standardization and automation of the test process, greatly improving the repeatability and accuracy of the test. By controlling the rotation of the bidirectional lead screw with the drive motor, the horizontal movement speed of the limit top plate and the magnitude of the pressure applied can be precisely controlled to ensure the consistency of the conditions for each test and avoid the uncertainty caused by manual operation in the traditional test method.

Detailed Description of the Preferred Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, the present utility model provides a technical solution: an ice pad compressive simulation test device, including a test frame 1, a lower base 2 is fixedly connected to the bottom end inside the test frame 1, and an upper base 201 is slidably connected to the center inside the test frame 1. The upper base 201 is located at the center of the top of the lower base 2, and the center of the top of the lower base 2 is slidably connected to the upper base 201. A measuring column 202 is fixedly connected to the center of the top surface of the lower base 2, and the top of the outer wall of the measuring column 202 is located on one side inside the upper base 201. A pressure display screen 203 is fixedly connected to one side of the bottom of the test frame 1, and a driving motor 3 is fixedly connected to the top end of one side of the test frame 1. A bidirectional lead screw 301 is rotatably connected to the top end inside the test frame 1, and both ends of the outer wall of the bidirectional lead screw 301 are rotatably connected to the top end inside the test frame 1 through the output end of the driving motor 3. The upper base 201 is located at the center inside the test frame 1, and both sides of the outer wall of the upper base 201 are slidably connected to the center inside the test frame 1 through the output end of the driving motor 3 and the threads on the outer wall of the bidirectional lead screw 301.

[0024] By arranging a limit support 205 on each side of the outer wall of the upper base 201, and passing the limit slide bar 204 through one side inside the limit support 205, by passing the limit slide bar 204 through the inside of the limit support 205, penetrating and slidingly connecting to one side inside the limit support 205, the limit support 205 and the upper base 201 can only move vertically along the outer wall of the limit slide bar 204 during movement, realizing the limit of the sliding trajectory of the upper base 201. By placing the measuring column 202 on one side of the top surface of the lower base 2, and the top of the outer wall of the measuring column 202 penetrates and slides inside one side of the upper base 201. When the device is performing a compressive test on the ice pad and driving the upper base 201 to press on the top surface of the ice pad along the limit slide bar 204, the corresponding position between the bottom surface of the upper base 201 and the scale on the outer wall of the measuring column 202 can be observed to accurately record the extrusion formation of the ice pad. After placing the ice pad at the center of the top surface of the lower base 2, by activating the drive motor 3 at the top end of one side of the test frame 1, the output end of the drive motor 3 drives the bidirectional lead screw 301 to rotate at the top end inside the test frame 1. Given that a set of corresponding limit slide frames 302 are arranged at the top end inside the test frame 1, and both sides of the top of the test frame 1 limit the limit top plate 303 through the limit slide frames 302, the limit top plate 303 can only move horizontally along the outer wall of the limit slide frame 302 during movement. Then, as the bidirectional lead screw 301 is driven by the output end of the drive motor 3, the bidirectional lead screw 301 drives a set of limit top plates 303 on both sides of the top of the test frame 1 to move towards the center of the outer wall of the bidirectional lead screw 301 along the outer wall of the limit slide frame 302 at the same time. And because a plurality of upper movable supports 304 and lower movable supports 305 are respectively arranged on the bottom surface of the limit top plate 303 and the top surface of the upper base 201, by arranging movable support rods 306 between the upper movable supports 304 and the lower movable supports 305, crossing the movable support rods 306 and cooperating with the limit slide bar 204, when the limit top plate 303 moves towards the center of the outer wall of the bidirectional lead screw 301, through the movable support rods 306 at both ends of its bottom cooperating with the limit slide bar 204, the upper base 201 is pushed to press on the top surface of the ice pad. Since a pressure sensor is arranged at the top end inside the lower base 2, the pressure is displayed through the display screen 203. At the same time of pressure detection, the limit compression amount of the ice pad can be recorded in cooperation with the measuring column 202. Thus, through the close cooperation between the movable support rods 306 and the limit slide bar 204, the compressive resistance test of the ice pad is realized, ensuring the standardization and automation of the test process, greatly improving the repeatability and accuracy of the test. By controlling the rotation of the bidirectional lead screw 301 through the drive motor 3, the horizontal movement speed of the limit top plate 303 and the magnitude of the pressure application can be accurately controlled, ensuring the consistency of the conditions for each test, avoiding the uncertainty caused by manual operation in the traditional test method, improving the reliability of the data and the test efficiency, and providing an important scientific basis for evaluating the performance of the ice pad product.

[0025] Such asFigures 1-4 As shown, the outer wall of the top end of the measuring column 202 is connected through the bottom surface of one side of the upper base 201, and the top of the outer wall of the measuring column 202 is slidably connected to one side inside the upper base 201. On both sides inside the test rack 1, a plurality of limiting slide rods 204 are fixedly connected at the same time, and the center of the outer wall of the limiting slide rod 204 is slidably connected with a limiting support 205. The limiting supports 205 are respectively located on both sides of the outer wall of the upper base 201, and both sides inside the limiting support 205 are slidably connected with the center of the outer wall of the limiting slide rod 204. The center of the outer wall of the limiting slide rod 204 penetrates and is connected to one side inside the limiting support 205, and the center of the outer wall of the limiting slide rod 204 is slidably connected to one side inside the limiting support 205.

[0026] By arranging a limiting support 205 on each side of the outer wall of the upper base 201 and passing the limiting slide rod 204 through one side inside the limiting support 205, through passing the limiting slide rod 204 through the inside of the limiting support 205, penetrating and slidably connecting with one side inside the limiting support 205, the limiting support 205 and the upper base 201 can only move vertically along the outer wall of the limiting slide rod 204 during movement, realizing the limitation of the sliding track of the upper base 201. By placing the measuring column 202 on one side of the top surface of the lower base 2 and making the top of the outer wall of the measuring column 202 penetrate and slide with one side inside the upper base 201, when the device is performing a compressive test on the ice pad and driving the upper base 201 to press against the top surface of the ice pad along the limiting slide rod 204, the corresponding position between the bottom surface of the upper base 201 and the scale on the outer wall of the measuring column 202 can be observed to accurately record the extrusion formation of the ice pad, thereby improving the accuracy and reliability of the test, ensuring the stability and accuracy of the vertical movement of the upper base 201 during the subsequent test process of the device, avoiding measurement errors caused by tilting or offset, and facilitating the subsequent compressive test of the ice pad by the driving motor 3 of the device.

[0027] Such as Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, on both sides of the top of the test rack 1, there are respectively fixedly connected with limit sliding frames 302, and the limit sliding frames 302 are located on both sides of the outer wall of the bidirectional lead screw 301. One end of the outer wall of the bidirectional lead screw 301 is penetrated and connected with one side of the inner wall of the test rack 1, and one end of the outer wall of the bidirectional lead screw 301 is penetrated and fixedly connected with the outer wall of the output end of the driving motor 3. At the top inside the test rack 1, there is a set of corresponding limit top plates 303 slidably connected through the limit sliding frames 302 at the same time, and the limit top plates 303 are respectively located at both ends of the outer wall of the bidirectional lead screw 301. One end of the outer wall of the bidirectional lead screw 301 is penetrated and connected with the center inside the limit top plate 303, and the bidirectional lead screw 301 is rotationally connected with the center inside the limit top plate 303 through the external thread on the outer wall. At both ends of the top surface of the limit top plate 303 and on both sides of the top surface of the upper base 201, there are respectively fixedly connected with a plurality of upper movable supports 304 and lower movable supports 305. The center inside the upper movable support 304 is rotationally connected with a movable support rod 306, and the bottom end inside the movable support rod 306 is rotationally connected with the center inside the lower movable support 305. The movable support rods 306 cross each other.

[0028] After placing the combined ice pad at the center of the top surface of the lower base 2, by activating the drive motor 3 located at the top end of one side of the test rack 1, the output end of the drive motor 3 drives the bidirectional lead screw 301 to rotate at the top end inside the test rack 1. Given that a set of corresponding limit slide frames 302 are provided at the top end inside the test rack 1, and both sides of the top of the test rack 1 limit the limit top plate 303 through the limit slide frames 302. The limit top plate 303 can only move horizontally along the outer wall of the limit slide frame 302 during movement. Then, as the bidirectional lead screw 301 is driven by the output end of the drive motor 3, the bidirectional lead screw 301 drives a set of limit top plates 303 on both sides of the top of the test rack 1 to move towards the center of the outer wall of the bidirectional lead screw 301 along the outer wall of the limit slide frame 302 simultaneously. And because a plurality of upper movable supports 304 and lower movable supports 305 are respectively provided on the bottom surface of the limit top plate 303 and the top surface of the upper base 201, by arranging the movable support rods 306 crosswise between the upper movable supports 304 and the lower movable supports 305 and cooperating with the limit slide rods 204, when the limit top plate 303 moves towards the center of the outer wall of the bidirectional lead screw 301, the upper base 201 is pushed to press the top surface of the ice pad through the cooperation of the movable support rods 306 at both ends of its bottom and the limit slide rods 204. Since a pressure sensor is provided at the top end inside the lower base 2 and the pressure is displayed through the display screen 203, the limit compression amount of the ice pad can be recorded in cooperation with the measuring column 202 while detecting the pressure. Thus, through the close cooperation between the movable support rods 306 and the limit slide rods 204, the compressive resistance test of the ice pad is realized, ensuring the standardization and automation of the test process, greatly improving the repeatability and accuracy of the test. By controlling the rotation of the bidirectional lead screw 301 through the drive motor 3, the horizontal movement speed of the limit top plate 303 and the magnitude of the pressure application can be precisely controlled, ensuring that the conditions of each test are consistent, avoiding the uncertainty caused by manual operation in the traditional test method, improving the reliability of the data and the test efficiency, and providing an important scientific basis for evaluating the performance of the ice pad product.

[0029] Working principle: By arranging a limit support 205 on each side of the outer wall of the upper base 201, and passing the limit slide bar 204 through one side inside the limit support 205. By passing the limit slide bar 204 through the inside of the limit support 205, penetrating and slidingly connecting with one side inside the limit support 205, when the limit support 205 and the upper base 201 move, they can only move vertically along the outer wall of the limit slide bar 204, realizing the limitation of the sliding trajectory of the upper base 201. By placing the measuring column 202 on one side of the top surface of the lower base 2, and the top of the outer wall of the measuring column 202 penetrates and slides inside one side of the upper base 201. When the device conducts a compressive test on the ice pad and drives the upper base 201 to press on the top surface of the ice pad along the limit slide bar 204, the corresponding position between the bottom surface of the upper base 201 and the scale on the outer wall of the measuring column 202 can be observed to accurately record the extrusion formation of the ice pad. After placing the ice pad at the center of the top surface of the lower base 2, by activating the drive motor 3 at the top end of one side of the test frame 1, the output end of the drive motor 3 drives the bidirectional lead screw 301 to rotate at the top end inside the test frame 1. In view of a set of corresponding limit slide frames 302 being arranged at the top end inside the test frame 1, and both sides of the top of the test frame 1 limit the limit top plate 303 through the limit slide frames 302. When the limit top plate 303 moves, it can only move horizontally along the outer wall of the limit slide frame 302. Then, as the bidirectional lead screw 301 is driven by the output end of the drive motor 3, the bidirectional lead screw 301 drives a set of limit top plates 303 on both sides of the top of the test frame 1 to move towards the center of the outer wall of the bidirectional lead screw 301 along the outer wall of the limit slide frame 302 at the same time. And because a plurality of upper movable supports 304 and lower movable supports 305 are respectively arranged on the bottom surface of the limit top plate 303 and the top surface of the upper base 201, by arranging movable support rods 306 between the upper movable supports 304 and the lower movable supports 305, crossing the movable support rods 306 and cooperating with the limit slide bar 204, when the limit top plate 303 moves towards the center of the outer wall of the bidirectional lead screw 301, through the cooperation of the movable support rods 306 at both ends of its bottom with the limit slide bar 204, the upper base 201 is pushed to press on the top surface of the ice pad. Because a pressure sensor is arranged at the top end inside the lower base 2, the pressure is displayed through the display screen 203. While detecting the pressure, the limit compression amount of the ice pad can also be recorded in cooperation with the measuring column 202. Thus, through the close cooperation between the movable support rods 306 and the limit slide bar 204, the compressive resistance test of the ice pad is realized.
