Description

Technical Field

[0001] The invention relates to the field of tension testing, in particular to a multi-directional heel tension testing machine. Background Art

[0002] High heels are a common type of shoe in women's daily life. By raising the height of the heels, the wearer can naturally stand on tiptoe, thereby raising the center of gravity of the body and increasing the wearer's height, making the wearer appear taller and more charming, and therefore they are loved by thousands of women.

[0003] The strength of the fixation between the heel and the sole of a high-heeled shoe directly affects the quality of the high-heeled shoe. Traditional heel strength tests usually conduct a tensile test on the heel in one direction from the toe to the heel. However, during walking, the heel is subjected to force in multiple directions, and the tensile test in other directions of the heel is easily overlooked. Therefore, it is necessary to conduct multi-directional strength tests on the heels of different types of high-heeled shoes, so as to provide important reference data for the quality evaluation and design development of high-heeled shoes. Summary of the invention

[0004] In order to overcome the shortcomings of the background technology, the purpose of the present invention is to design a multi-directional heel tensile testing machine, which fixes the heels of high-heeled shoes at multiple angles through a clamp, thereby performing multi-directional tensile tests on the heels, thereby providing important reference data for quality evaluation and design development of high-heeled shoes.

[0005] The technical solution adopted by the present invention is: a multi-directional heel tension testing machine, including a box body, a test bench on the box body, a moving block on the test bench, a turning platform and a transmission mechanism on the test bench, the turning platform and the transmission mechanism are respectively arranged at two ends of the test bench, a steering mechanism is arranged below the turning platform, a sole clamp is arranged above the turning platform, the transmission mechanism includes a moving seat, a sensor and a heel clamp, a screw rod and a motor are arranged in the box body, the moving seat is installed on the screw rod, one end of the screw rod is connected to the motor, one end of the sensor is connected to the moving seat, and the other end is connected to the heel clamp, so that the heel clamp and the sole clamp are on the same plane.

[0006] By adopting the above technical scheme, the box body is divided into a turning table part for fixing the sample shoes, and a transmission mechanism part for tensile testing. The sample shoes are fixed by the sole clamps above the turning table, and the force direction of the sample shoes is adjusted by the steering mechanism below the turning table, so as to meet the multi-angle tensile test requirements of the sample shoes. The heels are fixed by the heel clamps on the transmission mechanism, and the heel clamps are connected to the moving seat through the sensor, so that the heel clamps and the sole clamps are located at the same relative position on the same plane, so that the tensile direction is consistent with the test direction of the sensor, and the moving seat is moved by the transmission of the motor and the screw rod, thereby driving the sole clamps to apply tension to the sample shoes, and the tensile value is reflected by the sensor, so as to meet the test requirements.

[0007] The present invention is further configured such that the turning platform is rectangular as a whole and has a first mounting groove at one end and a mounting hole at the other end; the sole clamp is connected to the turning platform via the first mounting groove; and the steering mechanism is connected to the turning platform via the mounting hole.

[0008] By adopting the above technical solution, the sole clamp is connected to the turning platform through the first mounting groove, and the position can be adjusted through the first mounting groove to meet the testing of different shoe types. The mounting hole is arranged at one end of the turning platform, so that the heel of the sample shoe is close to the axis of the transmission shaft, so that the adjustment range of the heel clamp is reduced when testing other directions of the heel.

[0009] The present invention is further configured such that the steering mechanism includes a transmission shaft, a worm and a handwheel, one end of the transmission shaft is connected to the steering platform in a threaded manner, the other end of the transmission shaft is provided with a turbine, the worm is connected to the turbine and the axial direction of the worm is perpendicular to the axial direction of the transmission shaft, one end of the worm is connected to the handwheel, and the handwheel is installed on one side outside the box.

[0010] By adopting the above technical solution, the transmission shaft is connected to the handwheel through the turbine and the worm. The direction of the turning table on the transmission shaft is controlled by turning the handwheel, so that the turning table can be turned to the specified direction. The self-locking feature of the worm mechanism ensures that the turning table will not turn due to the pulling force of the heel clamp during the test, thereby reducing interference items in the test.

[0011] The present invention is further configured such that the sole clamp is provided with an upper clamp block, a lower clamp block, a connecting rod and a handle, both ends of the upper clamp block are provided with connecting rods, the upper clamp block is connected to the lower clamp block through the connecting rod, the handle is fitted with the upper end of the upper clamp block and the handle is connected to the connecting rod in a threaded manner.

[0012] By adopting the above technical solution, the toe of the sample shoe is fixed by the pressure between the upper clamp block and the lower clamp block. The upper clamp block is limited by the connecting rods at both ends so that the upper clamp block and the lower clamp block are misaligned when fixed. The handle can adjust the tightness of the upper clamp block and the lower clamp block on the sample shoe through the thread, thereby meeting the needs of replacing the sample shoe.

[0013] The present invention is further configured such that the heel clamp comprises a first mounting clamp, a second mounting clamp and a first universal joint, the first mounting clamp is provided with a first connecting pin, the second mounting clamp is provided with a second connecting pin, one end of the first universal joint is connected to the first mounting clamp, and the other end is connected to the second mounting clamp.

[0014] By adopting the above technical solution, a hole matching the first connecting pin is punched in the heel of the sample shoe before the installation process. The first connecting pin passes through the hole in the heel and is connected to the first mounting clamp, so that the heel cannot be separated from the first mounting clamp. A first universal joint is installed between the first mounting clamp and the second mounting clamp. The steering joint on the first universal joint ensures that the pulling direction of the sample shoe remains unchanged during rotation. The second mounting clamp is connected to the sensor through the second connecting pin.

[0015] The present invention is further configured such that the first mounting clamp and the second mounting clamp are overall in a "U" shape, the first connecting pin and the second connecting pin are respectively connected to the first mounting clamp and the second mounting clamp in a threaded connection manner, and the first universal joint is connected to the first mounting clamp at one end and to the second mounting clamp at the other end through a nut in a threaded connection manner.

[0016] By adopting the above technical solution, the first connecting pin passes through the heel of the sample shoe, the first mounting clamp is connected to the first connecting pin and its "U"-shaped structure is used to avoid interference between the heel and the heel clamp, thereby reducing interference factors in the tension test, and the steering joint on the first universal shaft is used to ensure that the direction of tension remains unchanged during the rotation of the sample shoe. The second connecting pin passes through the connecting hole of the second universal shaft, and the second mounting clamp is connected to the second connecting pin and its "U"-shaped structure is used to compensate for the angle of the sample shoe after the angle is adjusted, thereby avoiding the interference of the connecting parts affecting the test results.

[0017] The present invention is further configured such that the sensor is a pressure sensor, one end of the pressure sensor is provided with a connecting shaft, the other end is provided with a second universal shaft, the connecting shaft is connected to the moving seat, and the universal shaft is connected to the second connecting pin.

[0018] By adopting the above technical solution, a pressure sensor is installed between the heel clamp and the movable seat to effectively read the tension value on the heel of the sample shoe. One end of the pressure sensor is fixed to the movable seat through a connecting shaft, and the other end is connected to the second connecting pin through a second universal joint, thereby satisfying the angle compensation after the sample shoe is adjusted, avoiding the test results being affected by the interference of the connecting parts.

[0019] The present invention is further configured such that the movable seat is in an "L" shape as a whole, a second mounting groove is provided on the movable seat, and the connecting shaft is connected to the movable seat in a threaded manner through the second mounting groove.

[0020] By adopting the above technical solution, the movable seat, through its "L" shape, satisfies the requirement that the test direction of the pressure sensor is parallel to the plane of the test bench. The connecting shaft is fixed to the movable seat through the second mounting groove, and is threadedly connected to meet the requirement of adjusting the lateral position of the pressure sensor, thereby meeting the requirement of compensating for the position of the sample shoe after the angle is adjusted.
