Background

The traditional rotating handle design generally adopts a hardware rotating shaft finished product and realizes a rotating function by locking and attaching the hardware rotating shaft finished product on an upper/lower rotating body of the rotating handle through screws. This rotatory pivot discrete part of five metals is more, causes hardware mould and product group expense than higher, and the rotatory pivot occupation space of five metals is bigger, and little space handle still can't be practical, and the rotatory pivot of five metals is the electrodeless rotation mode of free state generally, can't reach the realization of stopping a function and rotatory feeling in the rotatory process, leads to partial user experience of product not good etc..

The existing scheme is that a hardware rotating shaft is mainly adopted to be locked on an upper/lower rotating body of a rotating handle through screws to realize a rotating function, and a hardware rotating shaft mold is divided into a plurality of pieces, so that the price of the mold and a single finished product is high. The rotation is generally a free rotation state, and the position can not be preset at a proper position, and meanwhile, the experience of rotating elastic hand feeling can not be met, so that the user experience of products is not good, and the like.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the handle device with the rotary pre-positioning function, the rotary pre-positioning function and the rotary hand feeling can be realized while the rotary action is finished in the using process, and meanwhile, the elastic force of the elastic body can be adjusted and replaced according to the hand feeling of different customers, so that the rotary hand feeling requirements of numerous customers are met. To achieve the above objects and other advantages in accordance with the present invention, there is provided a handle device with rotational pre-positioning, comprising:

the rotary sealing device comprises an upper rotary body, a lower rotary body nested in the upper rotary body, a central rotary supporting body fixed on the upper rotary body, a sealing base fixed on the lower rotary body and an elastic body fixed on the lower rotary body;

the middle of the lower rotating body is provided with a through hole, the central rotating support body is embedded in the through hole and fixed on the upper rotating body, the lower rotating body is at least provided with two elastomer mounting holes, and each elastomer mounting hole is internally provided with an elastomer.

Preferably, a central rotary support body installation area is arranged on the inner surface of the upper rotary body close to the lower rotary body, a screw fixing threaded hole is formed in the central rotary support body installation area, and one end face of the central rotary support body is in contact with the central rotary support body installation area and is fixed in the screw fixing threaded hole through screw fixing.

Preferably, the upper rotating body is provided with a plurality of grooves along the center of the upper rotating body as a circle center, the angle range of the included angle between each two grooves is adjustable, and the elastic body is matched with the grooves.

Preferably, the appearance piece is sleeved outside the upper rotating body, the upper rotating body is formed by double-material injection molding, and the appearance piece is fixedly connected with two rotating handles.

Preferably, the lower rotating body is formed by plastic injection, and the lower rotating body is in interference fit with the central rotating support body, so that the lower rotating body and the central rotating support body can rotate relatively.

Preferably, the elastomer includes an elastomer housing, a spring disposed in the elastomer housing, and an elastomer boss disposed on the spring, wherein the elastomer boss is disposed in the elastomer housing and moves in a vertical direction.

Compared with the prior art, the invention has the beneficial effects that: the upper rotating body 1 is driven to rotate through the force application rotating handle in the using process of the product, and the interference amount of the elastomer boss and the groove prepressing in the rotating process generates friction in the rotating motion to achieve hand feeling experience. When rotated into position, the elastomeric bosses spring back into the grooves to achieve a positional pre-fixing. The invention can realize the rotary pre-fixing of 360-degree division by a plurality of angles, and simultaneously can directly replace the elastic body to improve and optimize the pre-pressing amount and the pre-pressing pressure to finish the adjustment of the hand feeling comfort level, thereby facilitating the assembly and the maintenance, and saving the related materials, the labor and the after-sale maintenance cost.
