Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a ski boot board release force testing device. Background Technology

[0002] In skiing, the fastening system between ski boots and skis needs to release with appropriate force when a skier falls or suffers an accidental impact. This can prevent the ski boots from accidentally falling off due to insufficient release force, which would affect skiing safety, or avoid serious injuries such as ligament sprains and fractures due to excessive release force.

[0003] The ski boot release force testing equipment mainly consists of a frame, a loading system, force sensors, a data acquisition and control system, and a simulated ski platform. The frame provides stable support for the equipment; the loading system simulates the impact and torsional forces during skiing using electric cylinders or hydraulic devices; high-precision force sensors monitor and collect force data in real time at the moment of release; the data acquisition and control system processes and analyzes the data and compares it with standard parameters; and the simulated ski platform is used to mount and fix the skis and ski boots to be tested.

[0004] However, in actual use, most of the traditional equipment used for testing ski boot boards has a clamping structure that is only compatible with specific models of ski boot boards. It is not universal for ski boot boards of different sizes and shapes. When changing the test object, the clamps need to be changed frequently, resulting in low equipment utilization. In view of this, we propose a ski boot board release force testing device. Utility Model Content

[0005] The purpose of this invention is to provide a ski boot board release force testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ski boot board release force testing device includes a working platform, a support fixedly mounted on the bottom of the working platform, and a testing component disposed on the working platform, the testing component comprising:

[0008] A telescopic hydraulic device is provided, with one end of the telescopic hydraulic device fixedly installed above the working platform. A top plate is fixedly installed on the piston end of the telescopic hydraulic device, and a tension hydraulic device is fixedly installed on the top plate. A tension sensor is fixedly installed on the piston end of the tension hydraulic device.

[0009] The mounting cylinder has one end fixedly mounted on the other end of the tension sensor, and a square tube fixedly mounted on the other end of the mounting cylinder. A motor is fixedly mounted on the square tube, and a drive gear is fixedly mounted on the output end of the motor. A double-threaded rod is rotatably mounted on the square tube, and a secondary gear is fixedly mounted on the double-threaded rod.

[0010] A sliding rod is fixedly installed on the square tube. A clamping arm is threadedly installed on the double-ended threaded rod. A limit groove is opened on the working platform. A sliding cylinder is fixedly installed on the working platform. A limit plate is slidably installed on the sliding cylinder. A handle is fixedly installed on the limit plate.

[0011] In a further embodiment, the telescopic hydraulic device, clamping arm, slide cylinder, and limiting plate are provided in multiple sets, with the limiting plate positioned above the limiting groove.

[0012] In a further embodiment, the tension hydraulic device, tension sensor, mounting cylinder, square cylinder, motor, drive gear, double-threaded rod, auxiliary gear, slide bar, and clamping arm are positioned directly above the limiting groove.

[0013] In a further embodiment, the driving gear meshes with the auxiliary gear, the clamping arm slides on the slide rod, and the driving gear and the auxiliary gear are disposed inside the square tube.

[0014] In a further embodiment, the working platform is provided with an auxiliary component, the auxiliary component including a mounting slot, the working platform having a mounting slot and a sliding groove, one end of a spring rod being fixedly installed inside the working platform, the other end of the spring rod having a slider being fixedly installed, and a clamping block being fixedly installed on the slider.

[0015] In a further embodiment, multiple sets of the mounting groove, slide, spring rod, slider, and clamping block are provided.

[0016] In a further embodiment, the spring rod is disposed inside the mounting groove, the slider slides inside the mounting groove, the clamping block slides inside the groove, and the two ends of the clamping block are designed with rounded corners.

[0017] Compared with the prior art, this utility model provides a ski boot board release force detection device, which has the following beneficial effects:

[0018] 1. This ski boot separation force testing device, designed to improve the efficiency and reliability of ski equipment quality testing, incorporates a testing component. This component, in conjunction with a telescopic hydraulic device, drives the top plate to rise and fall, adjusting the tension sensor to a suitable height. The telescopic hydraulic device applies a vertically upward tension through the tension sensor, simulating the separation process of the ski boot from the binding. A motor drives the active gear to mesh with the secondary gear, rotating a double-ended threaded rod. This causes symmetrically distributed clamping arms to slide towards each other along the sliding rod. The precision of the threaded transmission achieves adaptive clamping of the ski boot. The sliding rod guide structure of the clamping arms ensures uniform distribution of clamping force, avoiding testing errors caused by clamping misalignment. Simultaneously, multiple sets of limiting plates, through the sliding cylinder and the limiting groove of the working platform, can quickly restrain the ski boot. Combined with real-time data feedback from the tension sensor, this enables accurate capture of the peak separation force.

[0019] 2. In order to improve the compatibility of the ski boot board separation force testing device with different models of ski boot boards, the device is equipped with an auxiliary component. This component, together with the spring rod, pushes the slider to slide in the installation groove through elastic deformation, so that the clamping block extends along the groove and fits against the bottom edge of the ski boot board to form multi-point support. The rounded corner design of the clamping block facilitates the quick installation of the ski boot board, while providing pre-tightening force to prevent the ski boot board from warping due to uneven force during testing.

[0030] Please see Figures 1-7 This utility model provides a technical solution:

[0031] A ski boot board release force testing device includes a working platform 1, with a bracket 2 fixedly installed at the bottom of the working platform 1. In one embodiment of this utility model, a testing component 3 is provided on the working platform 1. The testing component 3 includes a telescopic hydraulic device 31. One end of the telescopic hydraulic device 31 is fixedly installed above the working platform 1. A top plate 32 is fixedly installed on the piston end of the telescopic hydraulic device 31. A tension hydraulic device 33 is fixedly installed on the top plate 32. A tension sensor 34 is fixedly installed on the piston end of the tension hydraulic device 33. One end of the tension sensor 34 is fixedly installed on the other end of the tension sensor 34. A square tube 36 is fixedly installed on the other end of the mounting tube 35. A motor 37 is fixedly installed on the square tube 36. A drive gear 38 is fixedly installed on the output end of the motor 37. A double-threaded rod 39 is rotatably installed on the square tube 36. A secondary gear 310 is fixedly installed on the double-threaded rod 39. A sliding rod 311 is fixedly installed on the square tube 36. A clamping arm 312 is threaded onto the rod 39. A limit groove 313 is provided on the working platform 1. A slide cylinder 314 is fixedly installed on the working platform 1. A limit plate 315 is slidably installed on the slide cylinder 314. A handle 316 is fixedly installed on the limit plate 315. Multiple sets of telescopic hydraulic devices 31, clamping arms 312, slide cylinders 314 and limit plates 315 are provided. The limit plate 315 is located above the limit groove 313. A tension hydraulic device 33, a tension sensor 34, a mounting cylinder 35, a square cylinder 36, a motor 37, a drive gear 38, a double-threaded rod 39, a secondary gear 310, a slide rod 311 and clamping arms 312 are located directly above the limit groove 313. The drive gear 38 meshes with the secondary gear 310. The clamping arm 312 slides on the slide rod 311. The drive gear 38 and the secondary gear 310 are located inside the square cylinder 36.

[0032] In this embodiment, the ski boot to be tested is first placed on the work platform 1 and slid inside the limiting groove 313. The operator pushes the limiting plate 315 with the handle 316 to quickly restrict the position of the ski boot. Then, the telescopic hydraulic device 31 is activated, its piston end extends, and pushes the top plate 32 upward, adjusting the tension sensor 34, mounting cylinder 35, square cylinder 36, and other components to a suitable height, so that the clamping arm 312 is aligned with the appropriate position of the ski boot. Next, the motor 37 is started, and its output end drives the drive gear 38 to rotate. The drive gear 38 meshes with the secondary gear 310, driving the double-threaded rod 39 to rotate. Since the clamping arm 312 is threadedly mounted on the double-threaded rod 39 and slides on the slide rod 31, the clamping arm 312 is used to quickly restrict the position of the ski boot. On the 1st, the rotation of the double-ended threaded rod 39 causes the symmetrically distributed clamping arms 312 to slide towards each other along the slide rod 311, achieving adaptive clamping of the ski boot. The precision of the threaded transmission ensures that the clamping force is evenly distributed, avoiding detection errors caused by clamping misalignment. After the clamping arms 312 clamp the ski boot, the tension hydraulic device 33 is activated, and its piston end extends upward, applying a vertically upward tension through the tension sensor 34 to simulate the process of the ski boot board separating from the binding. The tension sensor 34 monitors the tension magnitude in real time and feeds the data back to the control system. As the tension gradually increases, when it reaches the separation force threshold of the ski boot board, the ski boot board begins to separate. Throughout the process, the control system accurately records the peak value of the tension, i.e., the separation force of the ski boot board.

[0033] In one embodiment of this utility model, an auxiliary component 4 is provided on the working platform 1. The auxiliary component 4 includes a mounting groove 41. The working platform 1 has a mounting groove 41 and a sliding groove 42. One end of a spring rod 43 is fixedly installed inside the working platform 1, and a slider 44 is fixedly installed on the other end of the spring rod 43. A clamping block 45 is fixedly installed on the slider 44. Multiple sets of mounting groove 41, sliding groove 42, spring rod 43, slider 44 and clamping block 45 are provided. The spring rod 43 is located inside the mounting groove 41, the slider 44 slides inside the mounting groove 41, and the clamping block 45 slides inside the sliding groove 42. The two ends of the clamping block 45 are designed with rounded corners.

[0034] In this embodiment, when the ski boot to be tested is placed inside the limiting groove 313, the auxiliary component 4 starts to work. The spring rod 43 pushes the slider 44 to slide in the mounting groove 41 through elastic deformation, so that the clamping block 45 extends along the sliding groove 42 and fits the bottom edge of the ski boot. Since the clamping block 45 has rounded corners at both ends, it is convenient to quickly install the ski boot. At the same time, multiple sets of clamping blocks 45 form multi-point support, providing pre-tightening force for the ski boot and preventing the ski boot from warping due to uneven force during testing.
