Problems solved by technology

[0003] The hinges that are commonly seen at present usually only have the function of rotation, and their limit and self-locking functions are realized by an additional locking mechanism. The disadvantage is that an additional locking mechanism is required, which will not only increase the weight, but also reduce the structural reliability.
In addition, the locking mechanism does not have a buffer function, resulting in a large impact on the hinge at the moment of locking, so there are high requirements for the impact resistance of the product

Abstract

The invention provides an elastic self-locking hinge. The hinge is composed of a fixed end, a rotating end, a pin shaft, an elastic element and an adjusting element. The rotating end and the fixed end are connected together through the pin shaft, a flange gradually heightened in the circumferential direction of a pin shaft hole is arranged on the corresponding matched face of the rotating end and the fixed end, a groove gradually deepened in the circumferential direction of the pin shaft hole is formed in the corresponding matched face of the fixed end and the rotating end, and the flange is matched with the groove; the pin shaft is provided with an external thread, and the adjusting element is in threaded fit with the pin shaft; the pin shaft is sleeved with the elastic element, and the elastic element is located between the adjusting element and the rotating end; through design of the flange on the rotating end and the groove in the fixed end, the simple elastic element and the simple adjusting element are additionally arranged on the pin shaft, and the aim that the elastic self-locking hinge has the rotating, buffer, limiting and self-locking functions is achieved; and the elastic self-locking hinge further has the beneficial effects of being small in weight, small is size and high in reliability.

Description

technical field [0001] The invention relates to the technical field of mechanical connection, in particular to an elastic self-locking hinge, which has the functions of rotation, buffering, position limiting and self-locking. Background technique [0002] In mechanism design, hinges are often used. In special occasions, such as deploying the locking mechanism, the hinge also needs to have the functions of rotation, buffering, position limiting and self-locking at the same time. [0003] The hinges that are commonly seen at present usually only have the function of rotation, and their limit and self-locking functions are realized by an additional locking mechanism. The disadvantage is that an additional locking mechanism is required, which will not only increase the weight, but also reduce the structural reliability. . In addition, the locking mechanism does not have a buffer function, resulting in a large impact on the hinge at the moment of locking, so there is a high req...
