Description

Technical Field

[0001] The utility model relates to the technical field of anti-skid testing machines, in particular to a dynamic anti-skid testing machine for shoes. Background Art

[0002] The dynamic anti-slip tester for shoes is a device used to test the anti-slip performance of shoes. This device can simulate the sliding of shoes on different friction surfaces to evaluate the anti-slip performance of shoes. The device can simulate different friction surfaces, such as wet, dry, oily, etc. During the test, the tester will place the shoes on the test platform and apply a certain amount of pressure to simulate the weight of the human body when walking. Then, the tester simulates the walking of the human body on different friction surfaces by controlling the sliding speed and direction. Through the test of the dynamic anti-slip tester, the anti-slip performance data of the shoes can be obtained. These data can be used to evaluate the quality, safety and performance of the shoes in different environments.

[0003] However, current testing machines can only move vertically up and down when fixing shoes, so many of them can only be used for shoes with flat bottoms. Since there is no way to adjust the angle of the shoes after they are fixed so that the front and back of the shoes can contact at the same time, when the heels are too high, incomplete contact is likely to occur, and shoes with non-flat bottom structures cannot be tested.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-6 As shown, the utility model provides a dynamic anti-skid testing machine for shoes, which is mainly used to test the anti-skid property of shoes. In addition to testing flat shoes, it can also adjust the angle of the shoes after being fixed by adjusting the fixture adjustment plate 11 to meet the needs of shoes with different sole heights. The specific structure mainly includes a panel 1 and a main frame 2 fixed on all sides and facing upward. The test operation is performed on the surface of the panel 1, which is the main platform for the test operation. Above the panel 1 is a main frame 2 supporting other structures, which is mainly used to fix the cylinder 15 for controlling the fixture bracket 10, and a hood 31 for protecting the clutch 26 and the servo motor 27 is added. A supporting and fixed base frame 17 is connected to the bottom of the panel 1. The base frame 17 can be provided with multiple spaces for placing items. Four directional wheels 18 fixed at the four corners are also provided at the bottom of the base frame 17. The test machine can be pushed to different places by the directional wheels 18 and locked so as not to move.

[0024] The surface of the panel 1 is provided with two slide rails 3, and at least two sliders 4 that move forward and backward are connected between the two slide rails 3. The surfaces of all the sliders 4 are commonly connected with a test base plate 5 that moves synchronously. Therefore, the test base plate 5 and the sliders 4 should be locked and fixed. The test base plate 5 is a medium in contact with the sole before the test. After the sole is pressed on the surface, it is moved to test its anti-slip property. The movement of the test base plate 5 mainly depends on the synchronous movement of the sliders 4 on the slide rails 3. Before the sole contacts the test base plate 5, different liquids can be sprayed on the surface of the test base plate 5 to test different anti-slip effects, including spraying water, oil, etc.

[0025] The surface of the panel 1 is provided with two shields 19 fixed on the outside of the two slide rails 3, and a front sample shield 20 for shielding the front end of the test base plate 5 and a rear sample shield 21 for shielding the rear end of the test base plate 5 are connected between the shields 19 on both sides. As the test base plate 5 moves, protective sample shields are set at the front and rear ends. In addition to protecting the two outer ends of the test base plate 5, the shields can also protect the first synchronous belt 8 at the bottom that drives the slider 4 to move.

[0026] A front synchronous wheel 6 fixed at the front end and a rear synchronous wheel 7 fixed at the rear end are provided between the two slide rails 3, a first synchronous belt 8 driving all the sliders 4 to move synchronously is connected between the front synchronous wheel 6 and the rear synchronous wheel 7, an assembly groove 22 for placing and fixing the first synchronous belt 8 is provided on the surface of the slider 4, the connection position of the first synchronous belt 8 driving the slider 4 to move at the bottom is fixed front and back, and a front synchronous wheel 6 and a rear synchronous wheel 7 rotating back and forth synchronously are respectively provided at the front end, and the two synchronous wheels 7 can allow the first synchronous belt 8 to move forward or reversely under the control of an external clutch 26 and a servo motor 27, thereby enabling the test base plate 5 to have the action of advancing and retreating and resetting. During the test, the test base plate 5 moves from the front synchronous wheel 6 to one end of the rear synchronous wheel 7.

[0027] Both sides of the front synchronous wheel 6 and the rear synchronous wheel 7 are provided with bearing seats 23 fixed on the surface of the panel 1, and a driving shaft 24 inserted and fixed in the middle and inserted into the bearing seats 23 on both sides for rotation. The driving shaft 24 is inserted through the rear synchronous wheel 7 and one end is also inserted with a synchronously rotating auxiliary synchronous wheel 25. A clutch 26 and a servo motor 27 are provided on the surface of the panel 1. A second synchronous belt 28 is connected between the clutch 26 and the auxiliary synchronous wheel 25. A third synchronous belt 29 is connected between the servo motor 27 and the clutch 26. The servo motor 27 provides sliding power, and drives the first synchronous belt 8 through the clutch 26 and the second synchronous belt 28.

[0028] A suspended cross-shaped fixture test plate 9 is provided above the test base plate 5, and fixture brackets 10 are connected to both sides of the fixture test plate 9 for synchronously pressing down on the test base plate 5. The fixture test plate 9 is used to fix the position of the shoe, and is generally assembled in the shoe with a shoe last, and then the shoe last is assembled under the fixture test plate 9, so that the sole is suspended above the test base plate 5. A plurality of fixing holes 30 are provided on the surface of the fixture test plate 9, and the user can fix the shoe in different positions for testing, and finally press down the fixture bracket 10 to make the sole contact with the test base plate 5, and then control the test base plate 5 to move to test its anti-slip property after contact. When pressing down, the user also needs to pay attention to the maximum distance when the fixture bracket 10 is pressed down.

[0029] A fixture adjustment plate 11 for adjusting the angle of the fixture test plate 9 is also provided between the fixture test plate 9 and the fixture bracket 10. The fixture adjustment plate 11 is provided with an arc groove 12 which is locked after rotation. The upper part of the fixture adjustment plate 11 is connected to the fixture bracket 10 and the tightness can be adjusted, and the lower part rotates with the fixed position of the upper part as the base point. The arc groove 12 also takes the fixed position of the upper part of the fixture adjustment plate 11 as the center of the circle. As the lower part of the fixture adjustment plate 11 rotates to different angles, it is locked with the fixture bracket 10 at a specified position in the arc groove 12 to complete the adjustment of the angle of the fixture test plate 9. The angle can be adjusted according to the different heights of the front and back of the sole.

[0030] Two sensor seats 13 are movably connected to the front end of the clamp bracket 10, a first sensor 14 is connected between the clamp bracket 10 and the sensor seat 13, a cylinder 15 is connected to the top of the clamp bracket 10, and the other end of the cylinder 15 is fixed to the bottom of the main frame 2 to control the lifting of the clamp bracket 10, and a second sensor 16 is connected between the cylinder 15 and the main frame 2. As the test base plate 5 moves, the first sensor 14 is mainly used to identify the force in the horizontal direction. At the same time, the second sensor 16 is used to identify the force pressing vertically downward on the surface of the test base plate 5. The user can get the anti-slip effect of the shoes based on the data obtained by the sensors in two directions.

[0031] Compared with the traditional technology, the present technical solution adds a fixture adjustment plate 11 which can adjust the angle of the sole between the fixture bracket 10 and the fixture test plate 9, so as to better adjust the contact between different soles and the test base plate 5, and can meet the testing needs of shoes with heels of different heights. At the same time, the first sensor 14 and the second sensor 16 are used to sense the forces in two directions respectively, so as to quickly obtain the anti-slip test data of the shoe in order to obtain the test results.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
