Abstract

The invention relates to a hidden circular arc meshing knob locking-type riser for a folding handle which comprises an upper component, a riser, a lower component, a screw hole cylinder and a knob bolt. The lower part of the upper component is provided with a portal sunk part. The position of the portal sunk part is provided with a bulge which is of a shape of a lateral surface of a cylinder. Thebulge is provided with a slot hole. The slot hole of the upper component is provided with a through hole in the vertical direction. The screw hole cylinder is inserted in the through hole. The knob bolt is screwed in the screw hole cylinder. The upper part of the upper component is connected with the riser. The base of the upper component is provided with a pin seat. The upper part of the lower component is of a dustpan shape. The middle part and the lower part of the lower component are respectively provided with a pair of ear clips. The pair of ear clips at the middle part of the lower component is rotatablely connected with the pin seat of the upper component. The dustpan-shaped edge opening of the lower component is in fit with the portal sunk part of the upper component. The dustpan-shaped inner arc of the lower component is meshed with the bulge which is of the shape of the lateral surface of the cylinder at the portal sunk part of the upper component. The top of the lower component is provided with a U-shaped opening. The U-shaped opening of the lower component corresponds to the slot hole of the upper component. The upper component and the lower component can be locked or loosened by screwing the knob bolt.

Description

technical field [0001] The invention relates to a folding handle riser, in particular to an aluminum forging or aluminum die-casting folding handle riser with hidden circular arc engaging knob locking type. technical background [0002] Currently on the market, it is difficult to find a folding handle riser with arc engagement locking type, and the hidden arc engagement knob locking folding handle riser is unheard of. Although a related locking scheme has been proposed, it is still not suitable for mid-to-high-end folding handle stems of aluminum forging or aluminum die-casting in terms of structural production technology, and there are also defects in shape. Room for improvement. Contents of the invention [0003] The object of the present invention is to provide a hidden circular arc engaging knob locking type folding handle riser with a structure suitable for aluminum forging or aluminum die-casting production. The purpose of the present invention is achieved in thi...
