Problems solved by technology

At present, some of the existing devices have the function of bearing rotation, and can also fix the rotation range, but they cannot effectively restore the original state. The reduction causes the rotating device to lose the original position recovery function, and some structures are complicated and the cost is too high

Abstract

The invention discloses a two-way rotating automatic reset spring elastic rotating shaft device and a handle using the same. The two-way rotating automatic reset spring elastic rotating shaft device comprises a main mandrel, an elastic body, limiting baffles and a casing, wherein the main mandrel penetrates through a perforation of the elastic body; two bumping posts of the main mandrel are respectively butted against two pins of the elastic body; the main mandrel penetrates through central holes of the two limiting baffles; the limiting baffles are fixed to the casing; the two pins of the elastic body respectively penetrate into clamping grooves of the corresponding limiting baffles; and an angle corresponding to the radian of each clamping groove is 90-135 degrees. According to the two-way rotating automatic reset spring elastic rotating shaft device provided by the invention, the free rotation of the main mandrel and the automatic reset of the main mandrel can be realized; and even if an elastic coefficient of the elastic body changes, the influence on the reset of the main mandrel can be avoided. In addition, the two-way rotating automatic reset spring elastic rotating shaft device is concise in design and convenient for assembly and mass production, so that the cost is low. The handle with the two-way rotating automatic reset spring elastic rotating shaft device is flexible in steering and can automatically reset.

Description

technical field [0001] The invention relates to a rotating shaft device capable of bidirectional rotation and automatic reset under the action of external force and a handle using the rotating shaft device. Background technique [0002] The existing bearing and rotating shaft device have the function of rotation, but cannot return to the original position after the rotation force is applied. In some special fields, such as the manipulation device of equipment with entertainment function, the elastic rotation device of mechanical equipment, etc., a device with bidirectional rotation function is often required, especially on the movable handle device in entertainment motion control. At present, some of the existing devices have the function of bearing rotation, and can also fix the rotation range, but they cannot effectively restore the original state. Even if there is a direction control device with automatic reset function, it will be affected by the aging of the elastic bod...
