Description

Technical Field

[0001] The present invention relates to the technical field of anti-skid testing, and more particularly to a temperature-controlled anti-skid testing box and a testing method. Background Art

[0002] Shoe anti-slip testers are specialized equipment used to test the anti-slip performance of shoes. This type of equipment is essential for evaluating the sole material, design, and overall shoe safety performance. Anti-slip performance is very important for many types of shoes, especially when walking on wet or slippery surfaces. The anti-slip performance of shoes directly affects the safety of the wearer. Existing anti-slip testers are all tested at room temperature and cannot change the temperature of the test surface. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention proposes a temperature-controlled anti-skid test box and a test method, in which the temperature in the test box is controlled by a freezing tube and a thermostat, so that the anti-skid test of the test shoes can be performed under low and high temperature environments.

[0004] According to a first aspect of the present invention, a temperature-controlled anti-slip test box is provided, and the technical solution is as follows:

[0005] A temperature-controlled anti-skid test box includes a control box, a test box, a fixed component, and a power component. The fixed component is slidably arranged in the test box, and is used to fix a shoe to be tested and drive the shoe to be tested to slide. The movable end of the power component is connected to the fixed component, and is used to drive the fixed component to slide. The control box is arranged on one side of the test box, and the control box is connected to the control end of the power component, and is used to control the movement of the power component. A pressure sensor and a test base plate are arranged at the bottom of the test box. The pressure sensor is located below the test base plate and is used to detect the pressure of the test shoe on the test base plate. The test base plate is provided with a bottom groove, and a freezing pipe is arranged in the bottom groove. The freezing pipe and the pressure sensor are electrically connected to the control box respectively.

[0006] According to a second aspect of the present invention, a skid resistance test method is provided, and the technical solution is as follows:

[0007] A skid resistance test method comprising the following steps:

[0008] Place the test base plate or test plate in the test box and fix the test shoe between the lower cleat and the upper cleat;

[0009] The height of the test shoe is adjusted by the crossbar so that the sole of the test shoe contacts the test bottom plate or the test plate. After the pressure sensor determines that the pressure reaches the target pressure, the position of the crossbar is fixed by the fastener;

[0010] The controller adjusts the temperature in the test box to the preset temperature through the thermostat;

[0011] The controller drives the test shoe to slide on the test bottom plate or the test plate by controlling the extension and retraction of the telescopic rod, and jointly determines the friction coefficient of the test shoe through the force of the test shoe driven by the telescopic rod and the pressure of the pressure sensor.

[0012] In summary, the above technical solution has the following beneficial effects: the bottom groove of the test base plate of the present application is used to hold water. When testing is required on an ice surface, the control box freezes the water into an ice surface through a freezing tube, and the temperature in the test box is also reduced to a lower temperature. In a low-temperature environment, the control box controls the test shoes to perform anti-skid performance tests on the ice surface through fixed components, thereby achieving the anti-skid condition of the test shoes in a low-temperature ice environment. When it is necessary to perform anti-skid tests on footwear in a high-temperature environment, a test plate is placed in the test box, and then the temperature in the test box is adjusted to a higher temperature through a thermostat to achieve anti-skid tests on test shoes in a high-temperature environment.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 3 As shown, a temperature-controlled anti-skid test box 20 includes a control box 10, a test box 20, a fixing component 30, and a power component 40. The fixing component 30 is slidably arranged in the test box 20, and is used to fix the shoes to be tested and drive the shoes to be tested to slide. The movable end of the power component 40 is connected to the fixing component 30, and is used to drive the fixing component 30 to slide. The control box 10 is arranged on one side of the test box 20, and the control end of the control box 10 and the power component 40 are connected, and are used to control the action of the power component 40. A pressure sensor 22 and a test base plate 21 are arranged at the bottom of the test box 20. The pressure sensor 22 is located below the test base plate 21 and is used to detect the pressure of the test shoe acting on the test base plate 21. The test base plate 21 is provided with a bottom groove 211, and a freezing pipe 212 is arranged in the bottom groove 211. The freezing pipe 212 and the pressure sensor 22 are electrically connected to the control box 10 respectively. The bottom groove 211 of the test base plate 21 of the present application is used to hold water. When testing is required on an ice surface, the control box 10 freezes the water into ice through the freezing tube 212, and the temperature in the test box 20 is also reduced to a lower temperature. In a low-temperature environment, the control box 10 controls the test shoe to perform an anti-slip performance test on the ice surface through the fixing component 30, thereby achieving the anti-slip condition of the test shoe in a low-temperature ice environment.

[0024] like Figure 4-Figure 6As shown, the fixing assembly 30 includes a transverse slide 31, a longitudinal slide 32, a transverse rod 33, a longitudinal rod 34, an upper clamp 35, a lower clamp 36 and a tensioning member 37; a sliding rod 23 extending in the horizontal direction is arranged in the test box 20, and the transverse slide 31 is provided with a transverse sliding opening for the sliding rod 23 to pass through, so as to slide along the sliding rod 23; there are two longitudinal slides 32 and they are respectively arranged on both sides of the sliding plate, and the two longitudinal slides 32 are provided with longitudinal sliding openings 321 in the vertical direction, and the transverse rod 33 passes through the two longitudinal sliding openings 321 for sliding in the vertical direction along the longitudinal openings; both ends of the transverse rod 33 exceed the longitudinal sliding openings 321, and both sides of the transverse rod 33 are provided with fasteners 331, and the fasteners 331 are used to fix the transverse rod 33 position; the longitudinal rod 34 is arranged on the cross rod 33, the upper splint 35 is arranged below the longitudinal rod 34, the upper splint 35 is provided with a connecting hole 351, and the lower splint 36 is provided with a connecting rod 361, the lower splint 36 is located below the upper splint 35, the connecting rod 361 is arranged through the connecting hole 351, and the connecting rod 361 fixes the lower splint 36 to the upper splint 35 through a tensioning member 37; the power component 40 is a telescopic rod, the fixed end of the telescopic rod is connected to the control box 10, the movable end of the telescopic rod is connected to the longitudinal slide 32, and the telescopic rod is used to drive the sliding frame to move along the extension direction of the sliding rod 23; a controller 11 is provided in the test box 20, and the controller 11 is electrically connected to the telescopic rod and the freezing pipe 212 respectively. After the test shoe is put on the lower clamp plate 36, let the lower clamp plate 36 cooperate with the upper clamp plate 35 to clamp the test shoe, tighten the lower clamp plate 36 by the nut and the connecting rod 361, adjust the height of the cross bar 33 to let the test shoe apply the specified pressure on the test base plate 21, and judge whether the pressure meets the requirements by the pressure sensor 22, and then fix the height position of the cross bar 33 by the fastener 331 to maintain the pressure of the test shoe on the test base plate 21. Finally, the fixing assembly 30 is driven to slide by the power assembly 40, so as to perform an anti-skid test on the test shoe. Specifically, the length of the sliding rod 23 is greater than the length of the horizontal slide plate 31, so that the two ends of the sliding rod 23 exceed the longitudinal slide opening 321, and the two ends of the sliding rod 23 are fixed to the longitudinal slide plate 32 by the fasteners 331. The fastener 331 is a nut, and the two ends of the sliding tube have threads.

[0025] like Figure 7 and Figure 8As shown, the connecting hole 351 on the upper clamping plate 35 is two waist-shaped holes, and two connecting rods 361 on the lower clamping plate 36 are provided corresponding to the two waist-shaped holes; the tensioning member 37 includes a front block 371, a rear block 372 and a tightening tooth 373, and the front block 371 and the rear block 372 are respectively provided with a waist-shaped hole for the connecting rod 361 to pass through, and the front block 371 is provided with a tightening channel 3711 on the side facing the rear block 372, and a rack 3721 extends from the side of the rear block 372 facing the front block 371, and the tightening tooth 373 is arranged in the tightening channel 3711 and meshes with the rack 3721, and the upper end of the tightening tooth 373 passes through the front block 371 and extends to the outside of the front block 371 to form a rotating handle, and the tightening tooth 373 is used to drive the rear block 372 to move along the tightening channel 3711, so that the front block 371 and the rear block 372 clamp the two connecting rods 361. Because the upper and sole of the test shoe are designed at different angles, sometimes the sole of the test shoe does not completely fit the test base plate 21 after the test shoe is fixed on the upper clamp plate 35 and the lower clamp plate 36. The waist-shaped hole of the tensioning member 37 and the upper clamp plate 35 is used to allow the connecting rod 361 on the lower clamp plate 36 to rotate, thereby changing the angle between the lower clamp plate 36 and the test base plate 21, so as to adapt to the soles with different tilt angles. After the angle of the lower clamp plate 36 is changed, the top surface of the connecting rod 361 and the upper clamp plate 35 are no longer perpendicular, and cannot be fixed by the nut. Therefore, the tensioning member 37 is used to close to the top surface of the upper clamp plate 35, and then the distance between the front block 371 and the rear block 372 is adjusted to tighten the two connecting rods 361, so that the lower clamp plate 36 can maintain the adjusted tilt angle.

[0026] A telescopic chamber 12 is provided in the control box 10. The side of the telescopic chamber 12 facing the test box 20 is connected to the test box 20.

In order to avoid the influence of the wear of the ice surface on the test results, the ice on the ice surface can be melted by the ironing block 14 and then re-frozen with a cooling pipe to make the ice surface smooth again.

[0027] The test base plate 21 is detachably connected to the test box 20. A power node 111 is provided on one side of the control box 10 facing the test box 20.

When the test base plate 21 is arranged at the bottom of the test box 20, the power node 213 contacts the power node 111, and the power node 111 is electrically connected to the controller 11. A test board 24 for detachably connecting to the test box 20 is also included. The test base plate 21 can be replaced, and the test board 24 can be made of any material, such as pressed ceramic floor tiles, glass, stainless steel plates, wooden boards, marble slabs, etc. When it is necessary to test on an ice surface, the test base plate 21 is placed in the test box 20. After the power node 213 is connected to the power node 111, the controller 11 controls the freezing pipe 212 to energize and cool. When it is not necessary to test on the ice surface, the test board 24 is replaced for testing.

The temperature sensor 113 is used to feedback whether the temperature in the test box 20 reaches the preset temperature. The thermostat 112 and the temperature sensor 113 are respectively connected to the controller 11 by telecommunication. After the test base plate 21 is replaced with a test plate 24 made of other materials, the thermostat 112 can control the control box 10 to generate high temperature, thereby testing the anti-skid performance of footwear at high temperature.

[0029] A box door 17 is provided on one side of the test box 20 , and the box door 17 is used to control the opening and closing of the test box 20 .
