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. The bulge 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
The present invention relates to a kind of foldable bar vertical pipe, particularly a kind of aluminium forging or aluminium die casting, hidden arc-engaging rotary knob locking type foldable handle stem.
Technical background
Foldable bar vertical pipe in the market, be difficult to seek the foldable bar vertical pipe of circular arc engaging lock compact form, hidden arc-engaging rotary knob locking type foldable handle stem is had never heard of especially, " the semicircle engagement hangs tight the locking type folding handle rod " that the design people formerly designs, although proposed relevant locking scheme, but on the production technology of structure, also be not suitable for aluminium forging or the sort of medium-to-high grade foldable bar vertical pipe of aluminium die casting, also deposit space to be improved in the moulding.
Summary of the invention
Purpose of the present invention, be to provide a kind of structure be fit to aluminium forging or the hidden arc-engaging rotary knob locking type foldable handle stem of aluminium Die Casting.The object of the present invention is achieved like this: hidden arc-engaging rotary knob locking type foldable handle stem, comprise upper-part, standpipe, lower member, screw cylinder and knob bolt, it is characterized in that: a shape depression is arranged at the bottom of upper-part, door shape recess becomes the planar projection of cylindrical side, prominence band slotted hole, on upper-part, be provided with a pair of perforation with slotted hole vertical, to being installed with the screw cylinder in the perforation, be screwed with the knob bolt in the screw cylinder, the top of upper-part is connected with standpipe, one key seat is arranged at the upper-part bottom, the top of lower member is the dustpan shape, a pair of earclip respectively is with in middle part and bottom, the a pair of earclip at lower member middle part and the key seat of upper-part are rotatably connected, the door shape depression of the bead of lower member dustpan shape and upper-part matches, the inner arc of lower member dustpan shape is meshed with the planar projection of cylindrical side of upper-part door shape recess, one U font opening is arranged at the top of lower member, the U font opening of lower member is corresponding with the slotted hole of upper-part, screw the knob bolt, can or unclamp upper-part and lower member locking.
The invention has the beneficial effects as follows: the door shape depression of upper-part is coincide with the dustpan shape bead of lower member to be cooperated, with with the inner arc of the planar projection of cylindrical side of upper-part door shape recess and lower member dustpan shape to engagement, so that the firmness behind the hidden arc-engaging rotary knob locking type foldable handle stem interlocking is better than in the market other foldable bar vertical pipe, this product adopts aluminium forging or aluminium die casting, makes the aesthetics of this product and class higher.
