Description

Technical Field

[0001] The utility model relates to the technical field of climbing auxiliary accessories, in particular to a flat belt universal joint. Background Art

[0002] In rope technology, universal joints are primarily used to connect ropes (or cables) to loads. They can also be used to connect sling loops and carabiners, as well as other climbing equipment such as safety belts and ropes. They rotate with the force applied to the rope, preventing entanglement and thus improving overall safety. Universal joints are crucial in high-risk activities such as industrial, mountaineering, and rock climbing, and their design and application play a vital role in ensuring safety in outdoor activities.

[0003] Universal joints currently on the market typically utilize an aluminum alloy design with ball bearings. Their freely rotating design effectively prevents rope entanglement caused by uneven force in complex and changing outdoor environments. However, inertia often makes their rotational speed difficult to control. Furthermore, the lack of anti-slip features on the attachment points of the universal joints means that the carabiners attached to them are prone to slipping and wiggling when used with large movements, compromising user safety and climbing efficiency, and failing to meet user requirements.

[0016] In order to more clearly illustrate the structural features, technical means and specific purposes and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0017] This embodiment: Figure 1-2As shown, the flat belt universal joint includes a hanging point portion 10 and a connecting portion 20. The hanging point portion 10 is used to connect a mountaineering buckle, and the connecting portion 20 is used to connect a flat belt. The hanging point portion 10 is rotatably mounted on the connecting portion 20 through a rotating pin 21. A ball bearing is provided in the hanging point portion 10. The rotating pin 21 is provided in the connecting portion 20 and passes through the connecting portion 20 and is inserted into the ball bearing, so that the hanging point portion 10 and the connecting portion 20 are rotatably connected. A silicone gasket 20 is provided on the outer sleeve of the rotating pin 21 to increase the damping during rotation, avoid the difficulty in controlling the rotation speed caused by inertia, and effectively slow down the rotation speed. The hanging point portion 10 is provided with an annular hanging point 11, and the inner ring of the annular hanging point 11 is equipped with a silicone ring 12. When it is buckled with the mountaineering buckle, the connection is firm, preventing sliding and swinging when the use range is large, effectively ensuring the safety of the user and the efficiency of climbing, meeting the use requirements, and the connecting portion 20 It is in the shape of an inverted U, and a detachable fixing pin 23 is installed between its two side walls.
