[0004] However, when the above-mentioned device is used, it detects the mattress rebound by pressing down on the pressure plate. It cannot simulate the dynamic pressure when people turn over and move around in bed, such as when a child jumps on the mattress and applies high-frequency pressure to the mattress. Therefore, it has certain limitations in the detection effect on the mattress. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mattress compression testing device, including a compression testing frame, a placement platform at the bottom of the compression testing frame, a mattress body placed on the placement platform, a linear drive assembly at the top of the compression testing frame, a bouncing simulation assembly on the linear drive assembly, and the linear drive assembly is used to drive the bouncing simulation assembly to move linearly along the surface of the mattress body, a pressure mold on the bouncing simulation assembly, and the bouncing simulation assembly is used to drive the pressure mold to alternately bounce up and down on the mattress body, and the bouncing simulation assembly is also provided with a depth adjustment assembly for adjusting the height of the pressure mold.

[0007] Preferably, the linear drive assembly includes a first threaded rod, which is rotatably connected to the top of the pressure testing frame. A first drive motor is provided on one side of the top of the pressure testing frame. The output end of the first drive motor is fixedly connected to one end of the first threaded rod. A slide is threadedly connected to the first threaded rod. T-shaped sliders are fixedly installed on both the front and rear sides of the top of the slide.

[0008] Preferably, the stomping simulation component includes multiple gear disks, which are distributed along a straight line at the bottom of the slide. Two adjacent gear disks mesh with each other. A second drive motor is provided on the right side of the bottom of the slide. The output end of the second drive motor is fixedly connected to one of the gear disks. A pin is fixedly connected to the off-axis of each gear disk. A horizontally arranged straight groove is slidably connected to the outer surface of the pin. A limiting frame corresponding to the straight groove is fixedly installed on the left side of the bottom of the slide. A vertically arranged limiting rod is fixedly installed on the limiting frame. A slip ring is fixedly connected to the side of the straight groove away from the gear disk. The slip ring is movably sleeved on the limiting rod, allowing the straight groove to slide vertically up and down along the limiting rod. A leg is fixedly installed at the bottom of the straight groove, and the pressing mold is vertically movably inserted into the leg.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a second drive motor to drive a gear disk to rotate, which in turn meshes with and drives the upper and lower gear disks to rotate. At the same time, a limiting rod and a slip ring limit the straight groove body, causing the insert on the gear disk to drive the straight groove body to move vertically up and down. This causes the pressure mold to step on the mattress body, achieving high-frequency pressure on the mattress body, simulating the dynamic pressure when people move the mattress a lot. Then, the rebound of the mattress body is observed and detected, thus the rebound effect of the mattress body under high-frequency pressure can be tested.

[0014] This invention, through the setting of a linear drive component and a depth adjustment component, enables the pressure mold to apply pressure to the entire surface of the mattress body for detection, expanding the detection range. At the same time, the connecting frame can drive the pressure mold to adjust its height up and down, thereby enabling the pressure mold to detect mattress bodies of different thicknesses. For mattress bodies of the same thickness, it can simulate users of different weights to create different depths of pressure, improving the diversity of mattress body detection methods.

[0024] Preferably, the linear drive assembly 4 includes a first threaded rod 41, which is rotatably connected to the top of the pressure testing frame 1.

A slide 43 is threadedly connected to the first threaded rod 41. T-shaped sliders 44 are fixedly installed on both the front and rear sides of the top of the slide 43. The slide 43 can slide linearly along the top of the pressure testing frame 1 through the T-shaped sliders 44.

[0025] Specifically, by driving the first threaded rod 41 to rotate through the first drive motor 42, the threaded rod 41 and the threaded transmission slide 43 move linearly, which allows the pressure mold 6 to apply pressure to the entire surface of the mattress body 3 for detection, thus expanding the detection range.

[0026] Preferably, the stomping simulation component 5 includes multiple gear disks 51, which are distributed along a straight line at the bottom of the slide 43. Two adjacent gear disks 51 mesh with each other. A second drive motor 52 is provided on the right side of the bottom of the slide 43. The output end of the second drive motor 52 is fixedly connected to one of the gear disks 51. A pin 53 is fixedly connected to the off-axis of each gear disk 51. A horizontally arranged straight groove 54 is slidably connected to the outer surface of the pin 53. A limiting frame 55 corresponding to the straight groove 54 is fixedly installed on the left side of the bottom of the slide 43. A vertically arranged limiting rod 56 is fixedly installed on the limiting frame 55. A slip ring 57 is fixedly connected to the side of the straight groove 54 away from the gear disk 51. The slip ring 57 is movably sleeved on the limiting rod 56, so that the straight groove 54 can slide vertically up and down along the limiting rod 56. A leg rod 58 is fixedly installed at the bottom of the straight groove 54, and the pressing mold 6 is vertically movably inserted into the leg rod 58.

[0027] Specifically, a gear disk 51 is driven to rotate by a second drive motor 52, which in turn meshes with the gear disk 51 to rotate vertically. At the same time, the limit rod 56 and the slip ring 57 limit the straight groove body 54, so that the insert 53 on the gear disk 51 drives the straight groove body 54 to move vertically up and down, so that the pressure mold 6 steps on the mattress body 3, simulating the dynamic pressure when people move the mattress a lot, and then the rebound of the mattress body 3 is observed and detected.

[0028] Preferably, multiple inserts 53 are alternately arranged on the gear disk 51, so that two adjacent pressure molds 6 can alternately jump up and down on the mattress body 3, thereby simulating the dynamic pressure on the mattress when a child jumps.

[0030] Specifically, following the same principle as the linear drive component 4 mentioned above, by increasing the drive of the third drive motor 71, the connecting frame 73 can drive the pressure mold 6 to adjust its height up and down. This allows the pressure mold 6 to test mattress bodies 3 of different thicknesses. For mattress bodies 3 of the same thickness, it can simulate users of different weights to create different depths of pressure, and then observe the rebound.

[0031] Preferably, the compression mold 6 is configured as a foot-shaped structure, which can further improve the detection effect of simulated jumping and stepping.

[0032] The working process of this utility model is as follows:

[0033] In use, the mattress body 3 is placed on the placement platform 2. Then, the first drive motor 42 drives the first threaded rod 41 to rotate, causing the threaded rod 41 to drive the slide 43 to move linearly. At the same time, the second drive motor 52 drives a gear disk 51 to rotate, which in turn meshes with the gear disk 51 to rotate vertically. Meanwhile, the limiting rod 56 and the slip ring 57 limit the straight groove body 54, causing the insert 53 on the gear disk 51 to drive the straight groove body 54 to move vertically up and down, so that the pressure mold 6 steps on the mattress body 3, simulating the dynamic pressure when people move the mattress significantly, thus completing the test.
