[0001] The utility model relates to the technical field of furniture detection equipment, in particular to a device for detecting the scratch resistance of furniture surfaces. Background Art

[0002] In the context of increasingly fierce competition, product quality has become the biggest competitive advantage. Traditional furniture surface scratch performance testing devices are often installed in a fixed position to test the scratching of the furniture pieces to be tested while they are rotating steadily;

[0003] However, in actual use, furniture often scratches against sharp objects at different degrees of inclination, causing damage to the furniture surface. For example, the furniture needs to be tilted and laid down during transportation, and the furniture surface is scratched by sharp objects during this process. In this way, the original testing equipment will have the defect of incomplete test results. For this reason, we propose a test device that changes the inclination angle between the furniture piece to be tested and the test needle, and simulates the scratching situation between the furniture piece to be tested and the test needle at different inclination angles to determine whether the scratching performance of the furniture piece is qualified.

[0027] The workbench 2 is also provided with an adjustment device for changing the inclination degree of the furniture piece to be inspected relative to the workbench 2, including a first mounting frame 4. There are two first mounting frames 4, and the two first mounting frames 4 are symmetrically installed on the upper end surface of the workbench 2. Threaded rods 5 and guide rods are arranged side by side in each first mounting frame 4. Each threaded rod 5 is sleeved with a screw nut 7. Two guide blocks are symmetrically arranged on the outer side of each screw nut 7. The two guide blocks are slidably connected to the outer side of the guide rod. One end of the threaded rod 5 is rotatably connected to the workbench 2 and is distributed vertically with the workbench 2. A motor 6 is arranged on the first mounting frame 4. The output end of the first mounting frame 4 is connected to the other end of the threaded rod 5, and the two ends of the guide rod are respectively connected to the workbench 2 and the first mounting frame 4.

[0028] In the actual working process, the furniture piece to be tested is clamped on the two clamping devices, and the two motors 6 are turned on asynchronously as needed. The output end of the motor 6 drives the threaded rod 5 to rotate. When the threaded rod 5 rotates, the external thread on the threaded rod 5 and the internal thread on the screw nut 7 engage with each other. At the same time, the guide block installed on one side of the screw nut 7 fits the guide rod, so that when the threaded rod 5 rotates, the screw nut 7 moves upward or downward. At this time, the adjustment devices on both sides of the workbench 2 adjust the clamping piece 10 to a suitable position, and turn on the test device. The scratch resistance of the furniture pieces to be tested with different inclination degrees is tested through the test device.

[0029] Preferably, the clamping device comprises a mounting ring 8, a connecting shaft 9 and a clamping member 10;

[0030] There are two groups of mounting rings 8, which are respectively mounted on the adjacent ends of the outer circumferences of the two screw nuts 7;

[0031] One end of the clamping member 10 is rotatably connected to the mounting ring 8 via the connecting shaft 9 .

[0032] When the two sides of the furniture piece to be inspected are respectively fastened to the two clamping devices, and the screw nuts 7 on the threaded rods 5 on both sides move up and down, the clamping device changes its inclination angle through the connecting shaft 9 as the screw nuts 7 move up and down through the cooperation between the mounting ring 8 and the connecting shaft 9. When the two clamping devices are not kept at the same height, the furniture piece to be inspected and the workbench 2 maintain a relative inclination.

[0033] Preferably, the detection device comprises a second mounting frame 11, a connecting rod 12, a fastening bolt 13, a locking nut and a test needle 14;

[0034] The second mounting frame 11 is slidably connected to the workbench 2 through the slide groove 3. The second mounting frame 11 is provided with a first through groove and a second through groove respectively. The connecting rod 12 is located in the first through groove and is slidably connected to the second mounting frame 11.

[0035] The fastening bolt 13 is located in the second through groove and passes through the connecting rod 12. The fastening bolt 13 passes through the outer peripheral surface of one end of the connecting rod 12 and is provided with an external thread that matches the locking nut. The connecting rod 12 is fastened to the second mounting frame 11 through the cooperation of the fastening bolt 13 and the locking nut.

[0036] By tightening the bolt 13 and cooperating with the second mounting frame 11 and the connecting rod 12, the connecting rod 12 can slide in the height direction on the second mounting frame 11 and be locked and fixed, so that the position of the test needle 14 can be adjusted to change the distance between the test needle and the furniture piece to be tested.

[0037] Preferably, the clamping members 10 are all U-shaped;

[0038] The clamping member 10 is provided with a threaded hole, and the furniture piece to be inspected is fastened to the clamping member 10 by bolts.

[0039] Preferably, two mounting blocks are symmetrically arranged on the lower end surface of the second mounting frame 11, and rollers are arranged on both sides of each mounting block;

[0040] A driving device for driving the roller to rotate and a controller for controlling the driving device are arranged in the mounting block, and a power supply is arranged in the detector 1. The power supply, the driving device and the controller are electrically connected.

[0041] Through the cooperation between the roller and the slide groove 33, the power supply provides power, and the driving device in the mounting block is controlled by the controller, so that the detection device reciprocates in the slide groove 3 through the cooperation between the roller and the mounting block, and effectively detects the furniture piece to be detected.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
