There are many types of shoe sole materials, which can be divided into natural sole materials and synthetic sole materials. The sole plays a very important role in the construction of a shoe and is an indispensable part. Therefore, finished shoe soles need to be tested and analyzed to ensure their quality.

An amplitude controller is fixedly connected to the end of the frame. This utility model has a simple structure, is convenient for testing, and is easy to implement. It has significant practicality, can improve work efficiency and quality, ensures the cleanliness of the work platform, and has huge economic benefits and broad market prospects, making it worthy of widespread use.

[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This shoe sole durability testing device, by setting up a connecting rod, a rope, a round rod, a movable rod, a piston, a spring, a rope, and a round tube, allows the shoe sole to be placed properly. Then, an electric push rod is activated to apply stable pressure to the sole for durability testing. Simultaneously, the piston moves upward, allowing air in the cavity to enter through the round tube and slotted holes, increasing the airflow area. This results in the internal pressure of the cavity being lower than the external pressure of the sole, thus pressing the sole firmly against the upper surface of the placement platform using the pressure difference. This ensures stable placement, improves testing stability, and avoids errors in the test results caused by deviation during testing.

[0016] 2. This shoe sole durability testing device, by setting up a round rod three, a hinge frame, a pressure plate, a spring two, a round sleeve one, a movable rod two, and a spring three, can cause the piston one to move upward when adsorbing the shoe sole, thereby driving the rope two to pull the movable rod two downward. This causes the pressure plate to rotate clockwise around the hinge of the hinge frame by a certain angle. After the pressure plate rotates, it will press the upper surface of the shoe sole, thereby improving the positioning effect of the shoe sole.

[0017] 3. This shoe sole durability testing device, by setting up a fixed rod, a simulation mold, an air bladder, an L-shaped tube, a connecting cavity, a second round sleeve, a second piston, a third movable rod, a fourth spring, and a pressure block, allows the shoe to be fitted onto the simulation mold. When the pressure plate rotates, its arc surface will press against the inclined surface of the pressure block, causing the pressure block to move to the right and push the third movable rod to slide. The third movable rod will drive the second piston to the right, thereby pushing the air in the second round sleeve into the air bladder through the connecting cavity and the L-shaped tube, causing the air bladder to expand. The expanded air bladder will then compress against the inner wall of the shoe, thus ensuring that the shoe is securely fitted onto the simulation mold for testing, improving the stability of the testing.

[0018] 4. This shoe sole durability testing device, by setting up a connecting frame, rack, gear, ratchet, trapezoidal locking block, movable rod four and spring five, can make the rotating rod rotate 90 degrees clockwise with the gear when the gear moves up and meshes with the rack, so as to replace different pressure components without manual replacement and improve the efficiency of testing.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7 One embodiment of the present invention is: a shoe sole durability testing device, including a base 1, a column 2 and a crossbeam 3, the bottom of the column 2 is connected to the top of the base 1, the crossbeam 3 is connected to the right outer wall of the column 2, and a placement platform 5 is provided on the top of the base 1.

The electric push rod 41 is installed at the top of the crossbeam 3 and its output end extends through the crossbeam 3 to the bottom of the crossbeam 3 and is connected to the top of the adjustment component 42. The replacement component 43 is located at the bottom of the adjustment component 42. The top of the placement platform 5 is provided with an annular groove and the interior is provided with a cavity 51. The top of the inner wall of the cavity 51 is provided with a strip hole 52. The top of the base 1 is provided with an adsorption component 6, which includes a connecting rod 61, a rope 62, a round rod 63, a movable rod 64, a piston 65, and a spring 66. The connecting rod 61 is connected to the left side of the adjusting component 42. The round rod 63 is connected to the inside of the rectangular groove 21. The rope 62 passes through the round rod 63 and is movably connected to it. The two ends of the rope 62 are connected to the top of the movable rod 64 and the left end of the connecting rod 61, respectively. The bottom of the movable rod 64 extends through the bottom of the inner wall of the rectangular groove 21 to the inside of the circular cavity 22 and is connected to the top of the piston 65. The spring 66 is located inside the circular cavity 22 and is sleeved on the outer wall of the movable rod 64. The L-shaped hole 23 is connected to the cavity 51 through the round tube 68. The left and right ends of the round tube 68 are connected to the right outer wall of the column 2 and the left outer wall of the placement platform 5, respectively. Movable rod 64 is slidably connected to column 2; the outer wall of piston 65 is slidably connected to the inner wall of cavity 22; both ends of spring 66 are connected to the top of the inner wall of cavity 22 and the top of piston 65, respectively; a pressure sensor is installed at the bottom of placement platform 5; a hinge frame 610 is connected to the top of placement platform 5, and a pressure plate 611 is hinged inside the hinge frame 610; one end of spring 612 is connected to the bottom of pressure plate 611, and the other end of spring 612 is connected to the top of placement platform 5; rope 67 is connected to the bottom of piston 65. One end of the rope 67 passes through the L-shaped hole 23 and the round tube 68, extending into the cavity 51 and through the top of the inner wall of the cavity 51 to the bottom of the pressure plate 611. The L-shaped hole 23 and the cavity 51 are respectively connected to the round rod 2 and the round rod 3 69. The rope 67 passes through the round rod 2 and the round rod 3 69 and is movably connected to them. The top of the pressure plate 611 is connected to the round sleeve 613. The inside of the round sleeve 613 is slidably connected to one end of the movable rod 614, and the bottom end of the movable rod 614 passes through the pressure plate 611. 1. Sliding connection with pressure plate 611; bottom end of movable rod 2 614 connected to the other end of rope 2 67; spring 3 615 installed inside circular sleeve 1 613, with both ends of spring 3 615 connected to the top of movable rod 2 614 and the top of inner wall of circular sleeve 1 613 respectively; the circular rod 1 63 is configured so that when connecting rod 61 moves down, rope 1 62 pulls movable rod 1 64 up; spring 1 66 is configured so that when rope 1 62 does not apply upward pulling force to movable rod 1 64, it drives piston 1 65 to reset and move down; L-shaped hole 23 and circular tube 6 The setting of 8 allows the circular cavity 22 to communicate with the cavity 51, allowing air in the cavity 51 to enter the circular cavity 22. The setting of the second and third circular rods 69 allows the second rope 67 to pull the second movable rod 614 downward when the piston 1 65 moves upward, thereby causing the pressure plate 611 to rotate. The annular groove is similar to the shape of a shoe sole. When the shoe sole cannot be placed flat to seal the strip hole 52, the shoe sole is placed upward and the shoe edge is inserted into the annular groove to achieve the effect of sealing the strip hole 52. If the shoe edge cannot fit to form a seal, water can be added to the annular groove to seal it. Working principle: By placing the shoe sole on the upper surface of the placement platform 5, the electric push rod 41 is activated to apply stable pressure to the shoe sole for durability testing. When the shoe sole is placed, the strip hole 52 is blocked and sealed. When the electric push rod 41 is activated, it drives the connecting rod 61 to move down through the adjusting component 42. When the connecting rod 61 moves down, it pulls the movable rod 64 up through the rope 62. When the movable rod 64 moves up, it drives the piston 65 to move up. When the piston 65 moves up, the air in the cavity 51 enters the cavity 22 through the round tube 68 and the L-shaped hole 23, which increases the air circulation area. As a result, the pressure inside the cavity 51 is less than the pressure outside the shoe sole. The shoe sole is then pressed tightly against the upper surface of the placement platform 5 by the pressure difference, making it stable and improving the stability of the test. This avoids errors in the test results caused by deviation during the test. Furthermore, during the testing of the sole, the piston 65 moves upward, reducing the pressure inside the cavity 51 and adsorbing and pressing the sole. At the same time, the rope 67 pulls the movable rod 614 downward when the piston 65 moves upward, causing the pressure plate 611 to rotate clockwise around the hinge of the hinge frame 610 by a certain angle. After the pressure plate 611 rotates, it will press the upper surface of the sole, thereby improving the positioning effect of the sole. Furthermore, rope 62 is loosely positioned inside the rectangular groove 21, allowing the detection component 4 room to move downwards. This prevents the detection component 4 from being unable to move downwards due to rope 62 being too short. When the detection component 4 applies pressure to the sole, even when the pressure reaches its maximum value, piston 65 does not move to the highest point. Moreover, piston 65 moves upwards to adhere and press the sole even before the detection component 4 contacts it. When the sole is doubly fixed, spring 612 is in a stretched state. The elastic force of spring 612 is less than that of spring 615, causing rope 67 to... When the movable rod 614 is pulled down, the spring 612 is stretched first, and the pressure plate 611 rotates. At the same time, the arrangement of the sleeve 613, the movable rod 614, and the spring 615 ensures that after the pressure plate 611 rotates to its maximum angle, the bottom right arc surface of the pressure plate 611 contacts the upper surface of the shoe sole. If the rope 67 continues to pull the movable rod 614, the spring 615 will be stretched to provide cushioning and prevent the rope 67 from being pulled after the pressure plate 611 has pressed against the shoe sole, which would cause motion interference and prevent the piston 65 from moving upward.

[0023] Please see Figure 1-7Based on the above embodiments, in another embodiment of the present invention, a positioning component 7 is provided on the top of the placement platform 5. The positioning component 7 includes a fixing rod 71 and a simulation mold 72. A threaded groove is provided on the top of the placement platform 5. The bottom of the fixing rod 71 is threaded into the inside of the threaded groove. The simulation mold 72 is connected to the top of the fixing rod 71. The bottom right side of the pressure plate 611 is provided with an arc surface. A connecting cavity 75 is provided inside the fixing rod 71. Airbags 73 are connected to the front and rear sides of the outer wall of the simulation mold 72. One end of an L-shaped tube 74 is connected to the outer wall of each airbag 73, and the other end of the L-shaped tube 74 is connected to the connecting cavity 75. The connecting cavity 75 is connected to a circular sleeve 7. 6. The second circular sleeve 76 is located on the left side of the fixed rod 71. The second circular sleeve 76 is slidably connected to the third movable rod 78, and the third movable rod 78 passes through the left end of the second circular sleeve 76. The end of the third movable rod 78 located inside the second circular sleeve 76 is connected to the second piston 77, and the outer wall of the second piston 77 is slidably connected to the inner wall of the second circular sleeve 76. The outer wall of the third movable rod 78 is fitted with the fourth spring 79, and the two ends of the fourth spring 79 are respectively connected to the left outer wall of the second piston 77 and the left side of the inner wall of the second circular sleeve 76. The left end of the third movable rod 78 is connected to the pressure block 710, and the pressure block 710 is provided with an inclined surface, and the inclined surface on the pressure block 710 contacts the bottom arc surface on the right side of the pressure plate 611.

[0024] Working principle: The simulation mold 72 resembles the shape of a foot, making it convenient to place the shoe cover to be tested on the simulation mold 72, so that the sole of the shoe faces upward for durability testing. By setting the bottom of the fixing rod 71 into the threaded groove to fix the simulation mold 72, the device can test individual soles or complete shoes, improving the applicability of the device. When the electric push rod 41 is activated after the shoe is placed on the simulation mold 72, the rope 67 pulls the movable rod 614 to rotate the pressure plate 611. When the pressure plate 611 rotates, its arc surface will squeeze the inclined surface of the pressure block 710, causing the pressure block 710 to move to the right and push the movable rod 78 to slide. The movable rod 78 drives the piston 77 to move to the right, thereby pushing the air in the circular sleeve 76 through the connecting cavity 75 and the L-shaped tube 74 into the airbag 73, causing the airbag 73 to inflate. The inflated airbag 73 squeezes against the inner wall of the shoe, thereby making the shoe securely placed on the simulation mold 72 for testing, improving the stability of the test. Furthermore, after the shoe is fitted onto the simulation mold 72, the sole has a certain height, which reduces the rotation angle of the pressure plate 611 when it rotates, thus preventing it from detaching when the pressure block 710 is squeezed, avoiding the inability to reset after detachment. The distance that piston 2 77 moves to the right is just enough to push the airbag 73 to inflate and fix the test shoe. When the pressure block 710 is not squeezed, spring 4 79 drives piston 2 77 to reset, causing the airbag 73 to contract, making it easy to remove the shoe.

[0025] Please see Figure 1-7Based on the above embodiments, in another embodiment of the present invention, the outer wall of the connecting rod 61 is connected to the front and rear sides of the limiting plate, and each limiting plate is slidably connected to the limiting rod 44. The two ends of each limiting rod 44 are respectively connected to the bottom of the crossbeam 3 and the top of the base 1. The adjusting assembly 42 includes a return frame 421, a motor 422, a lead screw 423 and a return moving rod 424. The motor 422 is installed at the right end of the return frame 421, and the left end of the lead screw 423 is rotatably connected to the left side of the inner wall of the return frame 421 through a bearing. The output of the motor 422 is... The left end of the shaft is connected to the right end of the lead screw 423, and the lead screw 423 passes through the return-shaped moving rod 424 and is threadedly connected to the return-shaped moving rod 424. The return-shaped moving rod 424 passes through the return-shaped frame 421 and is slidably connected to the return-shaped frame 421. The outer wall of the return-shaped frame 421 is connected to the front and rear sides of the connecting plate 425. The replacement component 43 includes a mounting block 431, a rotating rod 432, and four insert blocks 433. The rear end of the rotating rod 432 is rotatably connected to the front of the connecting plate 425 on the rear side of the return-shaped moving rod 424 through a resistance rotating shaft. The rotating rod 432 passes through the return-shaped moving rod 424. The front connecting plate 425 is rotatably connected to the connecting plate 425. The mounting block 431 is fixedly sleeved on the outer wall of the rotating rod 432. The mounting block 431 has slots on its four sides, and four insert blocks 433 are respectively inserted into the corresponding slots. Each insert block 433 is connected to the mounting block 431 by bolts, and four different pressure members are installed on one side of the outer wall of the four insert blocks 433. The front of the crossbeam 3 is provided with a rotating assembly 8, which includes a connecting frame 81, a rack 82, and a gear 83. The connecting frame 81 is connected to the front of the crossbeam 3, and the rack 82 is connected to the gear 83. 82 is connected to the front of the connecting frame 81. Gear 83 is rotatably sleeved on the outer wall of rotating rod 432. A circular groove is opened on the back of gear 83. A groove is opened on the top of rotating rod 432. The groove is slidably connected to movable rod 46. A trapezoidal locking block 85 is connected to the top of movable rod 46. A ratchet 84 is connected to the inner wall of the circular groove. A spring 5 87 is set inside the groove. The two ends of spring 5 87 are respectively connected to the bottom of movable rod 46 and the bottom of the inner wall of the groove. The top of trapezoidal locking block 85 fits into one of the radial grooves on the inner wall of ratchet 84.

[0026] Working principle: By integrating four different pressure components onto the mounting block 431, the device eliminates the need for repeated disassembly and replacement of different pressure components for testing. Replacement is achieved simply by rotating the mounting block 431, with each rotation being 90 degrees. The four different pressure components can simulate different road surfaces, thus enabling durability testing of shoe soles on various road conditions, improving the device's practicality. Activating the electric push rod 41 moves the mounting block 431 upwards, which in turn moves the rotating rod 432 upwards. The rotating rod 432 then moves the gear 83 upwards. As the gear 83 moves upwards, it meshes with the rack 82, causing clockwise rotation. After rotating 90 degrees, the rotating rod 432 stops moving upwards. Activating the electric push rod 41 again then moves the pressure components... When the component moves down for inspection, and gear 83 meshes with rack 82 and rotates clockwise, the top of trapezoidal locking block 85 is engaged in the radial groove of ratchet 84. This prevents ratchet 84 from pressing the inclined surface of trapezoidal locking block 85 when it rotates with gear 83. As a result, rotating rod 432 rotates clockwise with gear 83. When rotating rod 432 rotates clockwise, different pressure components can be replaced, allowing it to be tested vertically downwards. After replacement, gear 83 moves down, and the radial groove of ratchet 84 presses the inclined surface of trapezoidal locking block 85, compressing spring 87. Trapezoidal locking block 85 bounces repeatedly, preventing rotating rod 432 from rotating counterclockwise when gear 83 moves down. This avoids the mounting block 431 rotating again after the pressure component is replaced. Furthermore, by starting the motor 422, the lead screw 423 is driven to rotate in both directions. The lead screw 423, through the return-shaped moving rod 424 and the two connecting plates 425, drives the pressure component on the mounting block 431 to move left and right to adjust its position, so that the device can detect different positions on the sole of the shoe. The rotating rod 432 is installed through a damping rotating shaft, so that the mounting block 431 does not rotate when there is no force. Thus, after rotating to adjust different pressure components, the mounting block 431 does not rotate, so that the pressure component is detected vertically downwards.
