[0002] Bamboo wood flooring is a flooring material with bamboo or wood as the main raw material, which has many advantages and characteristics. Here are some key information about bamboo wood flooring: Bamboo wood flooring: It has good strength and toughness, and is usually processed through a compression process to form a hard board. It has the following advantages: Environmental protection: Bamboo grows quickly and is a renewable resource, which is more environmentally friendly than traditional wood. Durability: Bamboo wood flooring has high hardness and strong wear resistance, suitable for use in high-traffic areas. Aesthetics: The natural texture and color make it look elegant and suitable for a variety of interior styles. Comfort: It feels warm underfoot and has a certain degree of elasticity.

[0003] The structural strength test of bamboo wood flooring is an important part to ensure its safety and durability. The following are some of the main testing methods and standards: Static load test: By applying a constant weight, the deformation of the floor under a certain pressure is tested. Impact test: Simulate the impact that may be encountered in daily use to observe its ability to resist impact. Bending strength test: Measure the bending degree of the floor under a certain force to evaluate its load-bearing capacity. Shear strength test: Test the bonding strength between the floor layers to ensure the stability between the layers. Through these tests, the structural strength of the bamboo wood floor can be effectively evaluated to ensure that it meets the requirements of use.

[0004] The document with prior art publication number CN220568573U provides a transverse static bending strength detection device for bamboo and wood ecological boards. The transverse static bending strength detection of the test piece is completed by two supporting components installed on the bracket and the detection component. During the detection, the two protective covers are pulled to slide and assemble on the two guide rails to protect the test piece. The protective glass installed on the protective cover and the camera installed in the protective cover are used to observe the condition of the test piece during the detection. The two protective covers are used to protect the bamboo and wood debris from splashing out due to the high pressure, which facilitates subsequent cleaning and eliminates safety hazards.

A loading roller 702 is rotatably connected to the bottom of the load frame 7. A sponge 703 is fixedly connected to the bottom of the load frame 7. The sponge 703 is in frictional contact with the outer wall of the loading roller 702. A worm 704 is rotatably connected to one end of the load frame 7. A worm wheel 705 is fixedly connected to one end of the loading roller 702. The worm wheel 705 is meshingly transmitted with the worm 704. A universal joint B706 is fixedly connected to the other end of the worm 704. The other end of the universal joint B706 is rotatably connected to the load frame 7. A transmission wheel 707 is fixedly connected to one end of the universal joint B706. A rack 501 is fixedly connected to the fixed frame 5.

The spring B902 realizes the one-way transmission of the pushing teeth 901.

[0030] Working principle: When it is necessary to test the strength of the bamboo and wood board, first place the bamboo and wood board on the board rack 305. When it is necessary to place the board vertically, the two ends of the board are placed between the two auxiliary clamps 308. Under the action of the spring A309, the auxiliary clamps 308 clamp the board. Then the electric push rod 302 is used to drive the moving plate 303 to move upward. At this time, the pushing groove rack 304 on the moving plate 303 drives the connecting rod group 306 connected to the slide rod 307 to rotate, so that the board rack 305 drives the board to move upward, and cooperates with the fixing bar 201 to fix the board. Then the hydraulic cylinder 701 is used to drive the load frame 7 to move downward, and then the cover plate 8 will cover the detection cover 2, and then the loading roller 702 will press on the plate, and through continuous pressure, until the plate breaks, the strength test of the plate is realized. After the test is completed, the electric push rod 302 is used to drive the plate frame 305 to be retracted; Then, the hydraulic cylinder 701 is used to drive the load frame 7 to move upward and reset. Under the action of the rack 501, the transmission wheel 707 rotates, thereby driving the worm 704 connected to the universal joint B706 to rotate, so that the worm 704 drives the loading roller 702 connected to the worm wheel 705 to rotate. At this time, under the action of the sponge 703, the attached objects are cleaned; When the load frame 7 is moved up and reset, the pushing tooth 901 on the transmission frame 9 drives the one-way wheel 603 to rotate, so that the one-way wheel 603 drives the transmission rod 6 connected to the universal joint A602 to rotate, so that the transmission rod 6 drives the toggle rod 601 to rotate, so that the other end of the toggle rod 601 slides in the slide groove 402, thereby driving the limit plate 4 to move out of the detection cover 2. At this time, the rotating seat 301 does not contact the limit plate 4, and rotates under the action of its own weight, so that the broken plate and debris can fall into the receiving seat 101; When the tooth 901 is pushed off the one-way wheel 603, the tension spring A401 will drive the limit plate 4 to reset and insert it at the bottom of the rotating seat 301, support and limit the rotating seat 301, and then pull the material receiving seat 101 to take out the tested plate, and then release the material receiving seat 101, and the tension spring B102 will drive the material receiving seat 101 to reset.
