A rock climbing safety aid

Abstract

The invention relates to a rock climbing safety auxiliary device, which comprises a T-shaped sleeve, a screw rod arranged in the T-shaped sleeve, and a nut sleeved on the top of the screw rod. The screw rod is provided with grooves for accommodating staples, The ball hinge seat, spring, and T-shaped sleeve are provided with a hole for the staple to pass through. When in use, the climbing safety auxiliary device is inserted into a suitable rock seam, the nut is rotated, the screw rises, and the staple is released from the T-shaped The hole of the sleeve goes out, and then gets stuck on the inner wall of the rock crevice. The ball hinge seat and the spring can slide in the groove on the screw rod, so as to ensure that as many pitons as possible are clamped. The device can effectively guarantee the safety of rock climbing and prevent accidents from happening.

Description

【Technical field】 [0001] The invention relates to a rock climbing safety auxiliary device, in particular to an auxiliary device capable of improving rock climbing safety, and belongs to the field of sports equipment. 【Background technique】 [0002] Rock climbing is a popular adventure sport among young people. With corresponding safety devices, rock climbers can climb rock walls with bare hands. At present, there are many products related to the safety of assisted rock climbing, including rock ropes, safety belts, locks, etc., and how to ensure a firm grip on the rock wall is a very important safety consideration. The current commercially available products or patents on this Climbers insert the expansion nail into the rock crevice, and use the expansion principle to make the expansion nail clamp the inner wall of the rock crevice.

Problems solved by technology

At present, there are many products related to the safety of assisted rock climbing, including rock ropes, safety belts, locks, etc., and how to ensure a firm grip on the rock wall is a very important safety consideration. The current commercially available products or patents on this Climbers insert the expansion nail into the rock crevice, and use the expansion principle to make the expansion nail clamp the inner wall of the rock crevice. However, this method has a large potential safety hazard, because the rock wall belongs to Rocky mountain, the inner walls of its rock crevices are mostly jagged structures (see the appended description of the present invention). Figure 2b ), when the expansion nail expands to withstand the edge of the inner wall of the sawtooth, the rock climber thinks that it has been pressed tightly. Since the edge of the inner wall of the sawtooth is likely to be a thin-walled structure, it is easy to collapse and collapse under the action of a large impact force, which will cause Serious safety problem. At the same time, the expansion nail relies on the expansion force to press the inner wall of the rock crevice. After all, it relies on friction. Since the surface of the expansion nail itself is relatively smooth, and the inner wall of the rock crevice of the nature of the rock is relatively smooth, it will be smoother when it is subjected to a greater impact force. Slipping will occur under certain circumstances, which is also very dangerous; the expansion nails inserted into the rock cracks during the final rock climbing process will not be taken out, which will lead to fewer and fewer rock cracks available for latercomers, or the old expansion left in the early stage Nails are corroded, weathered and damaged. If the latecomers mistakenly think that it is safe to use directly, it will also cause very serious safety problems.
