Description

Technical Field

[0001] The utility model belongs to the technical field of sole testing devices, and in particular relates to a rigidity testing device for a flexing part of a sole. Background Art

[0002] The flexion rigidity refers to the force required to fix the forefoot of the entire shoe and bend the heel of the shoe to a specified angle along the bending line at a certain angular velocity. It is an important basis for evaluating the bending state and tension of the flexion part during the wearing of shoes. The flexion rigidity of footwear products depends on factors such as the hardness and thickness of the sole material and the structural design of the shoe. It determines the bending amplitude and structural changes of the flexion part of the shoe during wearing and use, and even to a certain extent determines the gait and stride of the wearer when walking.

[0003] Therefore, a device for testing the rigidity of the flexion part of the sole is provided. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a rigidity testing device for the flexion part of the sole.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A sole flexion part rigidity testing device comprises a clamping mechanism, a bending mechanism and a driving mechanism, wherein the driving mechanism drives the bending mechanism to rotate relative to the clamping mechanism;

[0007] The clamping mechanism is used to clamp the forefoot of the whole shoe. The clamping mechanism includes a clamping force-applying member, a hard base, a cushion block and a pressure block. The pressure block is located at the end of the clamping force-applying member. The hard base is located below the pressure block and forms a space for placing the forefoot of the whole shoe between the pressure block and the cushion block. The cushion block is located inside the forefoot of the whole shoe for support.

[0008] The bending mechanism includes an articulated rod, an articulated plate, a slide rail, a rear lifting plate and a force sensor. The articulated plate is hinged to a hard base via the articulated rod, the slide rail is arranged on the surface of the articulated plate, the rear lifting plate is slidably connected to the slide rail, and the force sensor is located inside the rear lifting plate.

[0009] It is further defined that the driving mechanism adopts a motor, and such a structural design makes the motor easy to control.

[0010] It is further specified that the pressure block does not contact the shoe upper surface other than the clamping part. With such a structural design, during the test, if the shoe upper surface other than the clamping part contacts the clamping mechanism, the force value recorded by the force sensor will become larger and cannot accurately reflect the actual value.

[0011] It is further defined that the hardness of the pressing block is greater than 75 Shore A. Such a structural design enables the pressing block to meet various test requirements.

[0012] It is further defined that when the sample to be measured is a men's shoe, the length dimension of the pressing block is 60±1mm, the width dimension is 60±1mm, and the height dimension is 25±1mm. With such a structural design, the men's shoes are wider, and the aforementioned dimensions are more suitable for men's shoes.

[0013] It is further defined that when the measured sample is women's shoes or children's shoes, the length dimension of the pressing block is 45±1mm, the width dimension is 45±1mm, and the height dimension is 25±1mm. With such a structural design, the size of women's shoes or children's shoes is smaller than that of men's shoes, and the above dimensions are more suitable for women's shoes or children's shoes.

[0014] It is further defined that the height of the hinged portion of the hinged plate and the hard base does not exceed the plane of the hard base. When the bending mechanism remains horizontal, the upper surface of the rear lifting plate and the surface of the hard base remain on the same horizontal plane. Such a structural design allows the shoes to be placed stably.

[0015] The beneficial effects of the utility model are as follows: a sole flexion part rigidity testing device is provided, which is used for general daily-wear shoes and has the advantages of simple structure, easy operation and accurate test results. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-4 As shown, a sole flexion part rigidity testing device of the utility model comprises a clamping mechanism, a bending mechanism and a driving mechanism, wherein the driving mechanism drives the bending mechanism to rotate relative to the clamping mechanism;

[0026] The clamping mechanism is used to clamp the forefoot of the whole shoe. The clamping mechanism includes a clamping force member 11, a hard base 12, a cushion block 13 and a pressing block 14. The pressing block 14 is located at the end of the clamping force member 11. The hard base 12 is located below the pressing block 14 and forms a space for placing the forefoot of the whole shoe between the cushion block 13 and the forefoot of the whole shoe for support.

[0027] The bending mechanism includes a hinge rod 21, a hinge plate 22, a slide rail 23, a rear lifting plate 24 and a force sensor 25. The hinge plate 22 is hinged to the hard base 12 through the hinge rod 21. The slide rail 23 is arranged on the surface of the hinge plate 22. The rear lifting plate 24 is slidably connected to the slide rail 23. The force sensor 25 is located inside the rear lifting plate 24.

[0028] In this embodiment:

[0029] When conducting the test, first confirm the bending line of the specimen;

[0030] Then, the sample is installed. According to the size of the sample, a pad 13 of appropriate specifications is selected. The pad 13 is placed in the forefoot part of the shoe. The width direction of the pad 13 is parallel to the bending line and its rear edge is 10mm in front of the bending line. The forefoot part of the sample is placed in the clamping mechanism so that the rigidity test bending line is parallel to the hinge axis of the edge of the hard base 12 and on the same vertical plane. According to the size of the sample, the position of the rear lifting plate 24 is adjusted along the slide rail 23 so that the center point of the force sensor 25 and the point 30mm from the heel to the toe on the central axis of the insole are on the same vertical line. The pressing block 14 is pressed tightly with a clamping pressure of 800±50N.

[0031] During the test, the driving mechanism starts from the horizontal plane 0° angle position, rotates the rear lifting plate 24 around the hinged part at an angular speed of 180±6° / min, and drives the rear lifting plate 24 to lift the heel of the sample until the angle reaches the specified force value. Figure 4 The scene in which the rear lifting plate 24 is rotated by an angle a is shown;

[0032] The force sensor 25 is located inside the rear lifting plate 24 and has an accuracy of ±1% within the range of 0-50N.

[0033] Preferably, the drive mechanism adopts a motor, and such a structural design makes the motor easy to control. In fact, other structural shapes of the drive mechanism can also be specifically considered according to specific circumstances.

[0034] Preferably, the pressing block 14 does not contact the shoe upper surface other than the clamping part. With such a structural design, during the test, if the shoe upper surface other than the clamping part contacts the clamping mechanism, the force value recorded by the force sensor 25 will become larger and cannot accurately reflect the actual value. In fact, other structural shapes that prevent the measured value from deviating can also be considered according to specific circumstances.

[0035] Preferably, the hardness of the pressing block 14 is greater than 75 Shore A. Such a structural design enables the pressing block 14 to meet various test requirements. In fact, other structural shapes of the pressing block 14 can also be considered according to specific circumstances.

[0036] Preferably, when the sample to be measured is a male shoe, the length dimension of the pressing block 14 is 60±1 mm, the width dimension is 60±1 mm, and the height dimension is 25±1 mm. With such a structural design, the male shoe is wider, and the aforementioned dimensions are more suitable for male shoes. In fact, other structural shapes of the pressing block 14 can also be considered according to specific circumstances.

[0037] Preferably, when the sample to be measured is a woman's shoe or a child's shoe, the length dimension of the pressing block 14 is 45±1 mm, the width dimension is 45±1 mm, and the height dimension is 25±1 mm. With such a structural design, the size of the woman's shoe or the child's shoe is smaller than that of the man's shoe, and the aforementioned dimensions are more suitable for the woman's shoe or the child's shoe. In fact, other structural shapes of the pressing block 14 can also be considered according to specific circumstances.

[0038] Preferably, the height of the hinged portion of the hinge plate 22 and the hard base 12 does not exceed the plane of the hard base 12. When the bending mechanism is kept horizontal, the upper surface of the rear lifting plate 24 and the surface of the hard base 12 are kept on the same horizontal plane. Such a structural design allows the shoes to be placed stably. In fact, other stable placement structures can also be considered according to specific circumstances.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
