[0014] 3. Beneficial effects

[0015] Compared with the prior art, the utility model has the advantages that:

[0016] This solution involves setting up a storage cylinder, rack, limiting rod, and limiting spring. After the device is put into use, it is moved above the furniture. The weight of the base pulls the rack downwards until the base reaches the top of the furniture. Workers then pull the levers on the outer wall of the storage cylinder one by one, causing the limiting rods to disengage from under each set of counterweights. This allows counterweights (one and two as a group) to slide down onto the base one by one, gradually increasing the weight on the top of the furniture until deformation occurs. The weight of the base is then added to the weight of each set of counterweights (one and two) to determine the furniture's load-bearing capacity. The data is generated by the staff connecting a ratchet wrench to the prismatic shaft on one side of the drive box. The ratchet wrench drives the cylindrical gear to rotate, causing the weighted chassis to lift counterweight one and counterweight two into the storage cylinder. As they enter the storage cylinder, one side of the top of each counterweight two will push the inclined edge of one end of the limit rod one by one until all counterweight one and counterweight two are inside the storage cylinder. One end of the limit rod will then stop the bottom of each set of counterweight two. Other furniture can then be tested. This device effectively improves the convenience of furniture load-bearing tests and allows staff to conduct load-bearing tests in different scenarios. Attached Figure Description
