Definitions

• the invention relates to a handle turning device for a stroller. Background technique
• the handle of a stroller is usually an umbrella handle (see FIG. 10).
• the umbrella handle is fixedly connected to the push rod, and the angle of the umbrella handle cannot be changed.
• the pusher since the heights of the pushers are different, there may be a phenomenon in which a tall pusher bends the cart while a short pusher raises his arm to push the cart, and the user feels inconvenient.
• the pusher After a long time push, the pusher also wants to change the posture and angle of the hand, so this umbrella handle cannot be suitable for users of various heights, and it cannot make the pusher comfortable with the wrist.
• An object of the present invention is to provide an umbrella handle pusher rotating device of an umbrella handle cart with an adjustable angle between the umbrella handle and the push rod.
• the technical solution of the present invention is that it includes a hook-shaped curved umbrella handle and a push rod connected to the umbrella handle, and the umbrella handle and the push rod are cooperatively connected by a rotating shaft, so that the umbrella handle is wound around the rotating shaft.
• the axis line of the rotating shaft is parallel to the axis line of the push rod; a position locking device is provided between the umbrella handle and the push rod.
• the position pinning device is provided with a connecting portion between the push rod and the umbrella handle.
• the connecting portion is a protrusion on one side inserted into a depression on the other side, and the protrusion or depression is formed by the rotation shaft.
• the center of the axis is arranged in a circumferential direction.

• FIG. 9 is a reduced structural diagram of Embodiment 2 of the present invention.
• Figure] 0 is a three-dimensional knot of the umbrella stroller; of which:
• the invention relates to an umbrella handle push handle rotating device for an umbrella handle cart, which comprises an umbrella handle handle (1) And a push rod (6) connected to the umbrella handle (1), the umbrella handle (1) and the push rod (6) are connected by a rotating shaft (9) to make the umbrella handle (1) revolvable
• the rotation shaft (9) rotates, and the axis line of the rotation shaft (9) is parallel to the axis line of the push rod (6), and preferably coincides; the umbrella handle (1) and the push rod (6) are arranged
• the position-stabilizing device may have a variety of medlars. In this embodiment, only three structures are described.
• the position locking device is provided with a connecting portion between the push rod (6) and the umbrella handle (1), and the connecting portion is a protrusion on one side of the umbrella handle (1) is inserted into the push rod (6) -side Inside the depression, or the opposite structure equivalent to the equivalent replacement; the pusher (6) -side protrusion is inserted into the depression on the side of the umbrella handle (1), and the protrusion or depression is the rotation shaft (9)
• the center of the axis is arranged in a circumferential direction as the center of the circle.
• An elastic device is provided between the push rod (6) and the umbrella handle (1) to make the connecting portion exceed the contact.
• the position pinning device is that the end surface of the umbrella handle (1) is provided with end teeth (10) arranged in a radial pattern, and the end surface of the push rod (6) is also provided The same end teeth as the end teeth (10) on the umbrella handle (1), the end teeth on the push rod (6) and the end teeth (10) on the umbrella handle (1) mesh with each other to form the At the connecting part, the cross section of the end face teeth is a triangular tooth or a trapezoidal tooth or an approximate triangular tooth or a trapezoidal tooth, so that the two end face teeth can slide relative to each other along the inclined surface that they contact to generate a rotation around the rotation axis (9) in the circumferential direction At the same time, axial movement occurs, so that the teeth on the end face bite and mesh with the next tooth to complete the angle adjustment of the umbrella handle (1).
• a spring (5) is provided between the push rod (6) and the umbrella handle (1) to make the end teeth of the two exceed the contact.
• the common shaft center of the umbrella handle (1) and the push rod (6) is provided with a turning pin (3), one end of the turning pin (3) is connected with the umbrella handle (1), and the turning pin (3) The other end is connected to one end of the pressure spring (5) sleeved on the rotating pin (3), and the other end of the pressure spring (5) is pressed against the push rod (6), so that the push rod (6) and the umbrella handle Push the end teeth between (1) above the contact.
• the position stabilizing device is that the end face of the push rod (6) is provided with a plurality of ball grooves (11) arranged in a circumferential direction with the axis of the shaft (9) as the center.
• the end surface of the umbrella handle (1) is provided with at least one elastic ball (8) that can be moved axially. It can be seen in Fig. 3 and 4 that two balls (8) are provided. A part of the ball (8) is embedded in the ball groove (11) to form the connection portion.
• a pivot pin (3) is provided at a common axis with the umbrella handle (1), and the umbrella handle (1) is provided with an axial spring hole (17), and the spring hole (17)
• a compression spring (7) is provided, and the outer end of the compression spring (7) is a ball (8).
• the ball (8) moves axially against the elastic force of the compression spring (7), and then enters the next ball groove to complete the angle adjustment of the umbrella handle.
• An equivalent alternative structure of the second embodiment is: the ball groove is set on the umbrella handle (1), and the ball and the spring hole are set on the push rod (6). 5 and FIG. 6 and FIG.
• the position stabilizing device is a ring-shaped outer ring (15) inserted in the inner sleeve (15) of the umbrella handle (1) on the push rod (6) ( 14) inside, the inner sleeve (15) is provided with at least one elastic bump (12) that can be moved radially, and two protrusions (12) are visible in FIG. 6 and FIG. 7, and the outer
• the inner wall surface of the bushing (14) is provided with a plurality of grooves (13) in a circumferential direction with the rotation axis (9) as a circle center, and the protrusions (12) are inserted in the grooves (13).
• the connecting portion is formed inside.
• the elastic bumps (12) are triangular teeth.
• An equivalent alternative structure of the third embodiment is as follows: the groove is provided on the umbrella handle (1), and the elastic projection is provided on the push rod (6) to form a structure inverted. There is also an equivalent replacement structure: a radial ball groove is provided on the umbrella handle (1), a radial spring hole is provided on the push rod (6), and a compression spring is arranged therein And balls on the free end of the spring. The spring forces at least a portion of the ball into engagement with the ball groove.
• the umbrella handle (1) is fixed with a turn (2). Since the umbrella handle (1) and the rotating sleeve (2) are rigidly connected as a whole, they are collectively referred to as an umbrella handle (1).
• a fixed sleeve (4) is fixed on the push rod (6). Similarly, since the push rod (6) and the fixed sleeve (4) are rigidly connected, they are collectively referred to as a push rod (6).
