Description

Technical Field

[0001] The utility model relates to the technical field of mountaineering equipment, in particular to a fatigue durability testing device for mountaineering crutch. Background Art

[0002] Trekking poles are assistive devices used in mountaineering. They offer numerous benefits for outdoor hiking and trekking, such as improved walking stability and reduced leg strain. However, over time, the locking pins that secure the extended poles can become ineffective, compromising their safety. To improve product quality, a test device was designed to determine the service life of the locking pins. Utility Model Content

[0003] The purpose of the utility model is to provide a fatigue durability testing device for a trekking pole, which has a reasonable structural design and can effectively test the service life of a fixed locking structure of a telescopic trekking pole.

[0004] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is:

[0005] A fatigue durability test device for a mountaineering crutch comprises a gantry support, a cylinder, a slider, a slide plate, and a counting pad. The gantry support comprises a top plate, a base, and a side support. The top of the cylinder is fixed to the lower end of the top plate of the gantry support via a pin, and the piston rod of the cylinder is fixedly connected to the top of the slider via bolts and nuts.

[0006] The slider is slidably connected to the slide plate, and both ends of the slide plate are fixedly connected to the side brackets. A counter I is fixedly provided on the slide plate. A top pin is provided on the slider, which contacts and connects with the top of the telescopic trekking pole. A binding belt is provided on the slider to fix the trekking pole.

[0007] The counting pad is fixed above the base, and the technical pad is provided with a counter II.

[0008] Furthermore, adjustment hole plates are provided on both sides of the slider, and adjustment holes are provided at different heights. The two ends of the top pin are pin rods with threads, which can be inserted and fixed in the adjustment holes at different heights. The middle lower end of the top pin is in contact with the top of the telescopic trekking pole.

[0009] The slide plate is fixedly provided with a T-shaped slide rail, the slider is provided with a T-shaped slide groove, and the T-shaped slide rail is slidably connected to the T-shaped slide groove.

[0010] The counting pad includes an upper plate, a lower plate, a guide column, a guide sleeve, a counter II, and a spring. The lower plate is fixedly connected to the base. Four guide columns are fixed to the lower end of the upper plate. The guide columns are connected to the guide sleeve through springs. The spring is arranged in the guide sleeve and sleeved on the guide column. Counter II is fixed on the lower plate.

[0011] Furthermore, a groove for limiting the position of the trekking pole is provided at the lower end of the slider, the depth of the groove is less than the maximum diameter of the trekking pole body, the groove contacts the trekking pole body, and the trekking pole is fixed to the slider by a binding belt.

[0012] The counter type I is an infrared recognition type, which counts once when the slider passes downward; the counter type II is an in-place contact type, which counts once when the base is pressed downward by the trekking pole.

[0013] Working Principle: When the cylinder extends, it drives the slider downward along the carriage plate. The bottom of the fixed telescopic trekking pole comes into contact with the counting pad, and the ejector pin on the slider drives the pole downward. When the bottom of the pole touches the upper plate, the spring is compressed, and the upper plate stops when the lower end reaches the guide sleeve. At this time, Counter II on the counting pad completes a count, and Counter I on the carriage also completes a count. When the cylinder returns, it drives the telescopic trekking pole upward, returning to the origin and entering the next cycle. Counters I and II, as well as the cylinder drive circuit, are connected to the controller. When the accumulated data of Counters I and II disagree, the controller sends a signal to stop the machine.

[0014] The beneficial effects of the utility model are:

[0015] The entire test device has a simple and reasonable structure and can effectively test the service life of the fixed locking structure of the telescopic trekking pole. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-2 Further explanation of this utility model:

[0020] like Figure 1-2 The device for testing fatigue durability of a mountaineering crutch shown in the figure comprises a gantry support 1, a cylinder 3, a slider 4, a carriage plate 2, and a counting pad 8. The gantry support 1 comprises a top plate, a base, and a side support. The top of the cylinder 3 is fixed to the lower end of the top plate of the gantry by a pin, and the piston rod of the cylinder 3 is fixedly connected to the top of the slider 4 by a bolt and nut.

[0021] The slider 4 is slidably connected to the carriage plate 2, and both ends of the carriage plate 2 are fixedly connected to the side brackets. A counter I 7 is fixedly provided on the carriage plate 2. A top pin 5 is provided on the slider 4, which contacts and connects with the top of the telescopic trekking pole 9; a binding belt 6 is provided on the slider 4 to fix the trekking pole 9;

[0022] The counting pad 8 is fixed above the base, and the technical pad is provided with a counter II 16.

[0023] Furthermore, adjustment hole plates are provided on both sides of the slider 4, and adjustment holes are provided at different heights. Both ends of the top pin 5 are pin rods with threads, which can be inserted and fixed in the adjustment holes at different heights. The middle lower end of the top pin 5 is in contact with the top of the telescopic trekking pole.

[0024] The slide plate 2 is fixedly provided with a T-shaped slide rail, and the slider 4 is provided with a T-shaped slide groove, and the T-shaped slide rail is slidably connected to the T-shaped slide groove.

[0025] The counting pad 8 includes an upper plate 11, a lower plate 15, a guide post 12, a guide sleeve 14, a counter II 16, and a spring 13. The lower plate 15 is fixedly connected to the base. Four guide posts 12 are fixed to the lower end of the upper plate 11. The guide posts 12 are connected to the guide sleeve 14 through a spring 13. The spring 13 is arranged in the guide sleeve 14 and is sleeved on the guide post 12. The counter II 16 is fixed to the lower plate 15.

[0026] Furthermore, a groove for limiting the position of a trekking pole is provided at the lower end of the slider 4. The depth of the groove is less than the maximum diameter of the trekking pole shaft. The groove contacts the trekking pole shaft, and the trekking pole is fixed to the slider 4 by a binding belt 6. The binding belt 6 can be made of 201 stainless steel cable ties, self-locking 4.6*200 marine low-temperature resistant metal cable ties.

[0027] The counter I7 is of infrared recognition type, and counts once when the slider 4 passes downward; the counter II16 is of in-position contact type, and counts once when the base is pressed downward by the trekking pole.

[0028] Working Principle: When cylinder 3 extends, it drives slider 4 downward along the carriage plate. The bottom of the fixed telescopic trekking pole flexibly contacts counter pad 8, and ejector pin 5 on slider 4 drives the pole downward. When the bottom of the pole touches upper plate 11, spring 13 is compressed, and the pole stops when the lower end of the upper plate reaches guide sleeve 14. At this point, counter II in counter pad 8 completes a count, and counter I on the carriage also completes a count. When cylinder 3 returns, it drives the telescopic trekking pole upward, returning to the origin and entering the next cycle. Counter I 7 and counter II 16, along with the cylinder drive device, can be connected to a controller via an electrical circuit. When the accumulated data of counters I and II disagree, the controller sends a signal to stop the cylinder.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in the technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention without paying any creative labor.
