It is an important foundation for establishing work and living spaces. However, existing methods for testing the load-bearing and impact resistance performance of furniture are limited. Traditional load-bearing tests rely on manual labor and simple tools, such as placing heavy objects directly on the surface of furniture for testing. This is inefficient, and the accuracy and consistency of test results are difficult to guarantee. Furthermore, it is difficult to control the placement and force of heavy objects when operating them manually. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a furniture load-bearing testing device, comprising: a support base 1; a first linear module 4 slidably disposed on the top of the support base 1, with a top sliding platform 5 mounted on the sliding slide of the first linear module 4; a limiting clamp 8 symmetrically slidably disposed on the top of the top sliding platform 5; a limiting frame 10 symmetrically slidably disposed inside the limiting clamp 8; a first support frame 2 mounted on the top of the support base 1 by bolts, with a second cylinder 11 mounted on the top of the first support frame 2, and the output end of the second cylinder 11 fixedly connected to a first support plate 13; a pressure sensor 25 mounted on the bottom of the first support plate 13, with a pressure plate 15 mounted on the bottom end of the pressure sensor 25; and a storage bag 17 placed above the support base 1, with multiple counterweights 18 disposed inside the storage bag 17.
[0027] It should be noted that in this embodiment, the furniture requiring load-bearing capacity testing is placed on the top sliding table 5. The device is centrally controlled by an external controller, and powered by an external power supply. The output of cylinder 7 drives the limiting clamp 8 to slide on the top sliding table 5. The output of servo motor 21 drives the bidirectional lead screw 19 to rotate. When the bidirectional lead screw 19 rotates, it drives the outer symmetrical sliding slider 20 to move. When the sliding slider 20 moves, it drives the limiting frame 10 to slide and adjust on one side of the limiting clamp 8. The limiting frame 10 restricts the movement of the furniture. The controller sends a command to the driver of servo motor 21, and the driver controls the servo motor 21 to work. The encoder detects the motion state of servo motor 21 and transmits the signal to the driver. In a closed loop, the position of the limiting frame 10 is adjusted. The position of the top sliding table 5 is adjusted by the sliding table of linear module 4. The main components of the linear module include: guide rail: providing linear guidance to ensure motion accuracy and stability; slider: moving along the guide rail, bearing the load and realizing linear displacement; transmission component: converting power into linear motion. The movement is achieved through a lead screw; the drive device provides the power source and controls the speed and position of the slider; the support base and bearings; and the outer casing and protective device. The top sliding table 5 adjusts the position of the furniture. The output of cylinder 11 drives support plate 13, pressure sensor 25, and pressure plate 15 downwards. Pressure plate 15 detects the furniture's load-bearing capacity. After detection by pressure sensor 25 and pressure plate 15, the sliding table of linear module 23 moves linear module 4 and top sliding table 5 as a whole, thus moving top sliding table 5... Move the furniture to a position below the storage bag 17, adjust the position of the furniture on the top sliding table 5 using the first linear module 4, place the counterweight 18 inside the storage bag 17, and drive the second support plate 14, connecting rope 16 and storage bag 17 upward through the output end of the third cylinder 12 to lift the storage bag 17 and counterweight 18 to a high position. Then, the third cylinder 12 lowers the second support plate 14, connecting rope 16, storage bag 17 and counterweight 18, dropping the storage bag 17 and counterweight 18 onto the furniture to perform an impact resistance test on the furniture.

Multiple fourth-level limiting rods 22 are symmetrically fixed to the top of the first support plate 13, and the fourth-level limiting rods 22 are slidably connected to the first support frame 2.
[0031] It should be noted that in this embodiment, the output end of cylinder 12 drives the second support plate 14 to move, the second support plate 14 drives the second limit rod 24 to slide in a limited position with the second support frame 3, and the output end of cylinder 11 drives the first support plate 13 and the fourth limit rod 22 to move, the fourth limit rod 22 slides in a limited position with the first support frame 2, thereby improving the stability of the adjustment.
[0032] In one embodiment, such as Figures 1 to 6 As shown, a bidirectional lead screw 19 is rotatably installed inside the limiting clamp box 8. A movable slider 20 is symmetrically installed on the outside of the bidirectional lead screw 19. The movable slider 20 is slidably connected to the limiting clamp box 8.
