Description

Technical Field

[0001] The utility model relates to the technical field of anti-skid testing of soles, in particular to a sole anti-skid testing device for footwear inspection. Background Art

[0002] The soles of shoes are in constant contact with the ground. If the anti-slip performance of the soles is poor, people will easily slip while walking in the shoes, and it will be difficult for people to walk on sloped roads. Therefore, during the shoemaking process, the anti-slip performance of the soles needs to be tested. The quality of the shoes can be judged based on the anti-slip performance of the soles, thereby improving the practicality of the shoes.

[0003] Patent announcement number CN221284804U discloses a sole anti-slip test device for footwear testing; the sole is placed on the test bench directly below the test plate, and then the hydraulic cylinder controls the downward movement of the test plate through the first telescopic rod, and the test groove at the bottom of the test plate covers half of the sole, and the pull plate drives the movement of the movable plate and the test plate through the driving rod, and the pull plate squeezes the driving plate, spring and second telescopic rod, and then releases the pull plate. When the spring resets, the pull plate, driving rod, movable plate, test plate and sole are pushed to move through the driving plate, and the monitoring device on the top of the test bench is used. Each time the driving plate is squeezed, the second pointer at the bottom of the driving plate can point to the number on the monitoring scale, so that the force of each push can be consistent, thereby ensuring the accuracy of the detection; and the first pointer on the outer wall of the test plate points to the number on the monitoring scale, so that the distance moved by the sole on the test bench can be intuitively seen. However, when the above-mentioned device tests the sole, half of the sole is covered by the test groove at the bottom of the test plate. However, the specifications of the test groove are not adjustable, so that the device cannot be applied to soles of different sizes, reducing the practicality of the device. Summary of the Invention

[0004] In order to improve the problem that the above-mentioned existing equipment, when testing the sole, covers half of the sole through the test groove at the bottom of the test plate, but the specifications of the test groove are not adjustable, so that the equipment cannot be applied to soles of different sizes, reducing the practicality of the equipment, the utility model provides a sole anti-slip testing device for footwear testing.

[0005] The utility model provides a sole anti-slip testing device for footwear testing, which adopts the following technical solutions:

[0006] A sole anti-slip testing device for footwear inspection includes a test bench, a vertical plate is installed at the center of the top of the test bench, a moving mechanism is provided at the upper end of the vertical plate, a second electric push rod is installed at the bottom of the left side of the moving mechanism, a clamping seat is installed at the bottom of the second electric push rod, a reserved groove is provided at the bottom of the clamping seat, a first electric push rod is installed at both ends of the inner wall of the reserved groove, two groups of the first electric push rods are installed at the ends close to each other, a fixing mechanism is provided at the end of the moving mechanism away from the second electric push rod, and a driving mechanism is provided at the bottom of the fixing mechanism.

[0007] By adopting the above technical solution, the sole to be tested is placed inside the reserved groove, and then the first electric push rod is controlled to extend. The extension of the first electric push rod drives the splint to move toward the sole until the two sets of splints clamp and fix the sole. The right end of the movable mechanism is fixed by the second electric push rod, and the fixing mechanism is driven to move to the right by the driving mechanism. When the fixing mechanism moves, it drives the movable mechanism to move to the right. After moving to a certain distance, the fixing effect on the movable mechanism is released by the fixing mechanism, and the movable mechanism moves to the left and then drives the sole to move to the left by the second electric push rod and the clamping seat. The anti-slip performance of the sole can be effectively detected by the distance moved by the sole on the test bench.

[0008] Optionally, the movable mechanism includes a movable rod, which is passed through the upper end of the vertical plate, the left end of the movable rod is connected to the mounting seat, the outer wall of the movable rod is provided with a reset spring, and the reset spring is located between the mounting seat and the vertical plate, and the right end of the movable rod is connected to the fixed seat.

[0009] By adopting the above technical solution, when the fixed seat moves to the right, the fixed seat drives the mounting seat to move to the right through the movable rod and compresses the reset spring. When testing is required, the fixed seat is released, and under the elastic force of the reset spring, the mounting seat moves to the left and can drive the sole below to move to the left.

[0010] Optionally, the fixing mechanism includes a shell, a bidirectional screw rod is connected to the interior of the shell, a forward and reverse motor for driving the bidirectional screw rod to rotate is installed on the top of the shell, both ends of the outer wall of the bidirectional screw rod are screwed with a second nut, the left ends of the two groups of second nuts are screwed with a connecting rod, and the ends of the two groups of connecting rods facing away from the second nut are installed with a movable plate, a limiting groove matching the connecting rod is opened on the left side of the shell, and a clamping mechanism is provided between the movable plate and the fixed seat.

[0011] By adopting the above technical solution, the forward and reverse motors drive the bidirectional screw to rotate when working, and the rotation of the bidirectional screw drives the two sets of second nuts to move up and down. When the second nuts move, the connecting rod drives the two sets of movable plates to move closer or farther away, thereby clamping or loosening the fixed seat.

[0012] Optionally, the clamping mechanism includes two groups of clamping blocks, which are respectively installed at one end of the two groups of movable plates close to each other, and the top and bottom of the fixing seat are provided with clamping grooves that are clamped with the clamping blocks.

[0013] By adopting the above technical solution, when the movable plate is fitted and connected to the fixing seat, the clamping block is clamped in the inside of the clamping slot, so that the connection between the movable plate and the fixing seat is more secure.

[0014] Optionally, the driving mechanism includes a bearing seat, which is installed at the right end of the top of the test bench, and connecting plates are installed at both ends of the top of the bearing seat, and a one-way screw is connected between the two groups of connecting plates. A servo motor for driving the one-way screw to rotate is installed on the outer side of the connecting plate at the right end, and a first nut is screwed to the outer wall of the one-way screw, and the top of the first nut is connected to the bottom of the shell, and the bottom of the first nut is connected to a slider, and a slide groove is opened on the top of the bearing seat, and the slide groove is slidably connected to the slider.

[0015] By adopting the above technical solution, the servo motor drives the one-way screw to rotate when it is working, and the one-way screw drives the first nut to move to the right. When the first nut moves, it drives the slider to slide inside the slide groove, thereby limiting the first nut and driving the movement when the first nut moves.

[0016] Optionally, a baffle is sleeved on the right end of the outer wall of the one-way screw rod.

[0017] By adopting the above technical solution, the position of the first nut is limited by the baffle, thereby ensuring that the distance of each movement is consistent, thereby ensuring the accuracy of the detection.

[0018] Optionally, pointers are connected to the front and rear sides of the clamping seat, and scale lines are engraved on the front and rear sides of the top of the test bench.

[0019] By adopting the above technical solution, the distance the sole moves on the test bench can be intuitively seen by pointing the pointer to the number on the scale line.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] Through the mutual cooperation of the clamping seat, the splint, the first electric push rod and the reserved groove, the sole to be tested is placed inside the reserved groove, and the sole is clamped and fixed by two sets of splints, which makes it convenient for the device to clamp soles of different specifications, thereby improving the universality of the device.

[0022] One end of the movable mechanism is fixed by the mutual cooperation of the clamping mechanism and the fixing mechanism, and the fixing mechanism is driven to move by the driving mechanism, thereby driving the movable mechanism to move, thereby facilitating the movement of the sole at the bottom of the clamping seat, so that the device does not require manual operation by the staff during the test process, thereby improving the practicality of the device.

[0028] The following is combined with Figure 1-3 The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3The present invention provides an embodiment of a sole anti-slip testing device for footwear inspection, comprising a test bench 7, a vertical plate 5 mounted at the center of the top of the test bench 7, a movable mechanism 9 disposed at the upper end of the vertical plate 5, the movable mechanism 9 comprising a movable rod 902, the movable rod 902 being horizontally passed through the upper end of the vertical plate 5, the left end of the movable rod 902 being fixedly connected to a mounting seat 904, the outer wall of the movable rod 902 being sleeved with a return spring 903, and the return spring 903 being located between the mounting seat 904 and the vertical plate 5, the right end of the movable rod 902 being fixedly connected to a fixed seat 901. When the fixed seat 901 moves to the right, the fixed seat 901 drives the mounting seat 904 to move to the right through the movable rod 902 and compresses the return spring 903. When testing is required, the fixed seat 901 is released, and under the elastic force of the return spring 903, the mounting seat 904 moves to the left, thereby driving the sole below to move to the left.

[0030] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 A second electric push rod 10 is mounted on the bottom of the left side of the moving mechanism 9. A clamping base 1 is fixedly mounted on the bottom of the second electric push rod 10. Pointers 14 are fixedly connected to the front and rear sides of the clamping base 1. Scale lines 13 are engraved on the front and rear sides of the top of the test bench 7. The distance the sole has moved on the test bench 7 can be intuitively seen by the number indicated by the pointer 14 on the scale lines 13.

[0031] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 , a reserved groove 4 is provided at the bottom of the clamping seat 1, and a first electric push rod 3 is fixedly installed at both ends of the inner wall of the reserved groove 4, and a clamping plate 2 is installed at the end of the two groups of first electric push rods 3 close to each other. A fixing mechanism 12 is provided at the end of the moving mechanism 9 away from the second electric push rod 10, and the fixing mechanism 12 includes a shell 1202, and the internal rotation of the shell 1202 is connected to a bidirectional screw rod 1207, and the top of the shell 1202 is installed with a screw rod for driving the bidirectional screw rod 1207 to rotate. The forward and reverse motor 1201 has a second screw nut 1206 screwed to both ends of the outer wall of the bidirectional screw rod 1207. The left ends of the two sets of second screw nuts 1206 are screwed to a connecting rod 1205. The ends of the two sets of connecting rods 1205 facing away from the second screw nuts 1206 are fixedly mounted with a movable plate 1204. The left side of the housing 1202 is provided with a limiting groove 1203 that matches the connecting rod 1205. A clamping mechanism 11 is provided between the movable plate 1204 and the fixed seat 901. When the forward and reverse motor 1201 is in operation, it drives the bidirectional screw rod 1207 to rotate. The rotation of the bidirectional screw rod 1207 drives the two sets of second screw nuts 1206 to move up and down. When the second screw nuts 1206 move, they drive the two sets of movable plates 1204 to move closer or further away via the connecting rod 1205, thereby clamping or releasing the fixed seat 901.

[0032] Please refer to the attached figure in the instruction manual Figure 2 The latching mechanism 11 includes two sets of latching blocks 1101, which are fixedly mounted on the adjacent ends of the two sets of movable plates 1204. The top and bottom of the fixed base 901 are each provided with a latching slot 1102 that latches with the latching blocks 1101. When the movable plates 1204 are snugly connected to the fixed base 901, the latching blocks 1101 latch into the inside of the latching slots 1102, making the connection between the movable plates 1204 and the fixed base 901 more secure.

[0033] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 A driving mechanism 6 is provided at the bottom of the fixing mechanism 12, and the driving mechanism 6 includes a bearing seat 606, which is installed at the right end of the top of the test bench 7. Connecting plates 601 are installed at both ends of the top of the bearing seat 606, and a one-way screw rod 604 is rotatably connected between the two sets of connecting plates 601. A servo motor 607 for driving the one-way screw rod 604 to rotate is installed on the outer side of the right end connecting plate 601. The outer wall of the one-way screw rod 604 is screwed with a first nut 602, and the top of the first nut 602 is connected to the bottom of the shell 1202. The bottom of the first nut 602 is fixedly connected to a slider 603, and a slide groove 605 is provided on the top of the bearing seat 606, and the slide groove 605 is slidably connected to the slider 603. When the servo motor 607 is in operation, it rotates the one-way screw 604, which in turn drives the first nut 602 to the right. The movement of the first nut 602 causes the slider 603 to slide within the slot 605, thereby limiting the position of the first nut 602. The movement of the first nut 602 also causes the movement of 1002. A baffle 8 is fixedly mounted on the right end of the outer wall of the one-way screw 604. This baffle 8 limits the position of the first nut 602, ensuring a consistent distance each time it moves, thus ensuring accurate detection.

[0034] Working principle: When in use, place the sole to be tested inside the reserved groove 4, and then control the first electric push rod 3 to extend. The first electric push rod 3 extends to drive the splint 2 to move toward the sole until the two sets of splints 2 clamp and fix the sole. Then the staff turns on the forward and reverse motor 1201. When the forward and reverse motor 1201 works, it drives the bidirectional screw rod 1207 to rotate. The bidirectional screw rod 1207 rotates to drive the two sets of second nuts 1206 to move and approach each other. When the second nut 1206 moves, it drives the movable plate 1204 to move and approach each other through the connecting rod 1205 until the two sets of movable plates 1204 are fitly connected with the fixed seat 901. At this time, the card block 1101 is inserted into the inside of the card slot 1102, so that the fixed seat 901 can be fixed.

[0035] Then turn on the servo motor 607. When the servo motor 607 is working, it drives the one-way screw 604 to rotate. Under the sliding cooperation of the slider 603 and the slide groove 605, the one-way screw 604 rotates to drive the first nut 602 to move to the right. When the first nut 602 moves, it drives the shell 1202 to move to the right. When the shell 1202 moves, it drives the fixed seat 901 to move to the right, and then the movable rod 902 can drive the mounting seat 904 to move to the right and compress the reset spring 903 until the first nut 602 abuts against the baffle 8. The position of the first nut 602 is limited by the baffle 8 to ensure that the distance of each movement is consistent, thereby ensuring the accuracy of the detection.

[0036] At this time, the forward and reverse motor 1201 is controlled to rotate in the opposite direction, so that the movable plate 1204 is separated from the fixed seat 901. Under the elastic force of the reset spring 903, the mounting seat 904 moves to the left, and then the sole can be driven to move to the left through the second electric push rod 10 and the clamping seat 1. The pointer 14 on the outer wall of the clamping seat 1 points to the number on the scale line 13, and the distance moved by the sole on the test bench 7 can be intuitively seen, which can effectively detect the anti-slip performance of the sole.

[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
