Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

The figure shows a strength and durability tester for furniture product quality inspection, including a horizontal working base plate 1 and a control cabinet 2. The characteristics of the horizontal working base plate are that the horizontal working base plate is a rectangular plate, an array of threaded holes 3 are arranged on the horizontal working base plate, a durability component 4 is arranged on each side of the horizontal working base plate, and a strength loading device 5 is arranged on one side of the horizontal working base plate. The durability component and the strength loading device are both fixedly connected to the horizontal working base plate by a column 6, and two through grooves 7 and 8 are opened at the bottom of the column. The two through grooves are perpendicular to each other, and the column is connected to the threaded holes on the horizontal working base plate by screws through the through grooves. The durable component is composed of an electric cylinder 9, a force sensor 10, a loading pad 11, a first support 12, a second support 13, a bearing 14, a guide rod 15, an electric cylinder fixing seat 16, a third support 17, a column locking seat 18, and an image recognition module 19. The electric cylinder is connected to the column locking seat by the electric cylinder fixing seat through the third support, the column locking seat is fixed to the column, the electric cylinder output rod is connected to the first support, the first support is connected to the force sensor, a loading pad is fixed on the top of the force sensor, the second support is fixed on the electric cylinder, a bearing is fixedly installed on the second support, the guide rod is connected to the first support through the bearing, and the image recognition module is fixedly installed on the first support. The strength loading device is composed of a hand wheel 20, a screw rod 21, a nut block 22, a digital dynamometer 23, a first support plate 24, a guide rail 25, a slider 26, a locking screw with a handle 27, a second support plate 28, a tension rope 29, a first pulley 30, a second pulley 31, a first connecting member 32, a locking seat 33, a movable pulley rod 34, and a third pulley 35. The first connecting member is fixedly connected to the first support plate and the second support plate at both ends, the locking seat is fixedly connected to the middle of the first connecting member, and the locking seat is connected to the column 6. A guide rail is installed on the upper part between the first support plate and the second support plate. A screw is installed at the lower part, a nut block is installed at the top of the screw, a handwheel is installed at the other end of the screw, a slider is slidably connected to the guide rail, a locking screw with a handle is installed on the slider corresponding to the guide rail, a second pulley and a first pulley arranged up and down are installed at the lower end of the second support plate, a movable pulley rod movable vertically is fixedly installed on the outer side of the second support plate, a third pulley movable up and down along the movable pulley rod is installed on the movable pulley rod, a digital dynamometer is installed on the nut block, the digital dynamometer is wound by a tensile rope around the second pulley, and the first and third pulleys are connected to the sample 36 to be tested.

During the test, the touch screen on the control cabinet is used to set the loading force value, loading sequence, loading frequency and number of loading times, etc. The sample to be tested is fixed in the middle of the horizontal working base plate, and the electric cylinder outputs, and the force is applied to the tested position on the sample through the loading pad (for example, the electric cylinders on the four durable components in Figure 1 are loaded on the four sides of the table panel respectively, and the force is applied in a cycle in turn). The image recognition module is used to identify whether there is damage or abnormality such as fracture or crack at the loading position.

During the loading process, image recognition determines that there is damage or abnormality such as breakage or cracking. The control cabinet can be used to control the test pause, record the number of loading times, and issue a sound alarm.

One end of the tension rope is connected to the digital dynamometer, and the other end is connected to the sample under test through the gap between the first pulley and the second pulley, so that horizontal force can be applied. If a certain angle of force needs to be applied to the sample, one end of the tension rope can be connected to the digital dynamometer, and the other end can be connected to the sample under test through the gap between the first pulley and the second pulley, and then bypass the third pulley to connect to the sample under test. The loading angle can be changed by changing the position of the third pulley.

By shaking the handwheel, the lead screw drives the nut block and the digital dynamometer to move backward, and the tensile rope applies force to the sample. When the force requirement is reached, the locking belt handle locks the screw, and the position of the slider and the nut block is locked to help achieve a stable force value. The loading time is up to complete the test.

It can be used for strength test of furniture, such as furniture lock strength test. When the furniture lock is locked, horizontal force is applied to the drawer or door, 30° force in the horizontal direction, -30° force in the horizontal direction, and force loading in different directions is achieved through the pulley to test the locking strength of the furniture lock in the furniture.
