Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and in particular to a steering mechanism and a parasol. Background Art

[0002] Center-column umbrellas, a popular choice among consumers, are a key category of parasols. However, they also have their drawbacks in practical use. Since morning and afternoon sunlight falls at a specific angle, and the center-column umbrella's canopy is perpendicular to the ground, sunlight can penetrate the center-column during these times, preventing it from providing adequate shade. A system that could freely adjust the canopy's vertical angle to the ground would effectively block the morning and afternoon sunlight. Adjusting the angle requires a steering mechanism. Existing steering mechanisms on the market use a single button design, resulting in a poor user experience and weak steering strength. These mechanisms can cause wobbling after prolonged use. Furthermore, existing steering mechanisms have a central crossbar, which interferes with the drawstrings when the parasol is opened and closed, causing friction. This can wear out the drawstrings over time, impacting their lifespan and the number of times the parasol can be opened and closed. This new steering mechanism, however, is hollow in the center and does not interfere with the drawstrings. Summary of the Invention

[0003] A first object of the present invention is to provide a steering mechanism that is easy to operate and can conveniently realize the flipping and positioning of a first steering body and a second steering body through an elastic locking mechanism.

[0004] The second purpose of the present invention is to provide a parasol, which can easily adjust the position of the umbrella surface through the setting of a steering mechanism, thereby achieving a better sunshade effect; at the same time, it can also avoid wear of the pull rope during operation.

[0030] Combine Figures 1 to 5As shown, this embodiment provides a steering mechanism, including a first steering body 1, a second steering body 2, and an elastic locking mechanism for locking and unlocking the first steering body 1 and the second steering body 2 when they are flipped over; wherein, the first steering body 1 and the second steering body 2 are hinged to each other and are hollow through-set. In order to facilitate the pivoting of the first steering body 1 and the second steering body 2, preferably, a pivot groove 11 is provided at the end of the first steering body 1, and the pivot end of the second steering body 2 is inserted into the pivot groove 11 and connected by radially arranged pivot shafts 31 and 32. In order to prevent the pull rope (for driving the pull rope) from passing through the hollow through-set cavity of the first steering body 1 and the second steering body 2 The opening and closing of the umbrella canopy) generates friction with the pivot shaft 3. It is further preferred that two pivot shafts 31 and 32 are provided and are coaxially arranged on opposite sides of the pivot groove 11, so that there is no pivot shaft at the hollow position, thereby effectively avoiding friction with the pull rope, and then effectively improving the service life of the pull rope; in addition, in order to limit the flipping angle between the first steering body 1 and the second steering body 2, a limiting portion 11 for limiting the flipping angle of the second steering body 2 is further provided on the inner wall of the pivot groove 11. The limiting portion 11 is a protrusion protruding from the inner wall of the pivot groove 11. When the second steering body 2 flips to this position, its flipping can be restricted by this protrusion.

When the first steering body 1 and the second steering body 2 are in a coaxial position, the positioning groove and the positioning protrusion arranged on the top of the elastic locking piece are in a clamped state, that is, the first steering body 1 and the second steering body 2 are locked by the elastic locking piece.

[0032] Furthermore, the above-mentioned elastic locking member includes a locking member 51 arranged axially along the first steering body, a baffle 53 arranged at the lower end of the cavity of the first steering body 1, and a spring 52 arranged between the baffle 53 and the locking member 51; in order to make the locking member 51 move axially along the first steering body 1 smoother, this embodiment also provides guide protrusions 511 on both opposite sides of the two ends of the locking member 51, and an inclined wall is provided on the same side of the guide protrusion 511, and the inclined wall is slidably matched with the positioning groove 12 provided in the cavity of the first steering body 1, so as to better position and guide the locking member 51, thereby avoiding abnormalities such as jamming during axial movement along the first steering body 1.

[0033] There are two elastic locking members 51 with the above-mentioned structural design, and the locking members 51 are respectively cooperated with the buttons 4 provided on the side wall of the first steering body 1. When the two buttons 4 are pressed synchronously, the two elastic locking members 51 are separated from the second steering body 2 by the action of the two buttons 4. At this time, the first steering body 1 and the second steering body 2 are in an unlocked state; when the two buttons 4 are released synchronously, the elastic locking members 51 are engaged with the second steering body 2 by the action of the two buttons 4. At this time, the first steering body 1 and the second steering body 2 are in a locked state.

[0034] Furthermore, in order to facilitate the movement of the above-mentioned two locking members 51 by pressing the two buttons 4, the two buttons 4 in this embodiment are both slidably matched with the corresponding locking members 51 through a wedge-shaped structure; specifically, the wedge-shaped structure includes a wedge-shaped protrusion 512 that is inclined and extends outward from the side wall of the locking member 51, and a wedge-shaped groove provided on the inner wall of the button 4, and the wedge-shaped protrusion 512 slides with the wedge-shaped groove; when the button 4 is radially pressed, the wedge-shaped protrusion 512 is squeezed by the wedge-shaped groove and moves along the axial direction of the first steering body 1 toward one end away from the second steering body 2.

[0035] In addition, in order to facilitate the connection between the two buttons 4 and the corresponding locking members 51 and prevent the buttons 4 from falling off the side wall of the first steering body 1, it is preferred that male buckles 513 are provided on the upper and lower sides of the wedge-shaped protrusion 512 of the above-mentioned locking member 51, and the male buckle 513 is engaged with the female buckle 41 provided on the inner wall of the button 4.

[0036] This embodiment also provides a parasol, including any one of the steering mechanisms mentioned above. The steering mechanism not only facilitates the adjustment of the angle of the umbrella portion connected to the second steering body 2, but also avoids friction between the pull rope passing through the steering mechanism for controlling the opening and closing of the umbrella portion and its structure, thereby effectively improving the quality and service life of the parasol.
