Description

Technical Field

[0001] This utility model relates to the field of umbrella technology, specifically to an umbrella nest structure and an umbrella. Background Technology

[0002] With continuous technological advancements, umbrella design has undergone numerous evolutions, transforming from simple rain protection tools into modern products with multiple functions such as rain protection, sunshade, and wind resistance. However, existing umbrellas still have shortcomings, particularly in terms of structural stability, as many designs do not adequately consider external forces (such as strong winds and impacts).

[0003] The opening and closing mechanism of traditional umbrellas relies on a simple spring-loaded buckle design, which cannot effectively prevent the spring-loaded buckle from unlocking when the umbrella is open. Especially under severe external force conditions, this can easily lead to instability of the umbrella canopy and affect the protective effect of the umbrella. Utility Model Content

[0040] Example 1

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides an umbrella nest structure, including an upper nest 10 and a lower nest 11. At least one latching portion 102 is provided on the outer surface of the upper nest 10; the lower nest 11 includes a sliding sleeve 111 that slides along the umbrella's central rod and a locking sleeve 112 fitted over the sliding sleeve 111. The locking sleeve 112 is provided with a travel limiting portion 1122 that restricts the axial sliding of the sliding sleeve 111; the locking sleeve 112 is provided with a locking portion 1121 that engages with the latching portion 102; one end of the sliding sleeve 111 is provided with at least one unlocking portion 1112 that separates the locking portion 1121 from the latching portion 102; the upper nest 10 is provided with a clearance notch 103 at the latching portion 102 to avoid the unlocking portion 1112.

[0042] Specifically, the upper canopy 10 is fixedly mounted at the top of the umbrella's central rod, and the sliding sleeve 111 of the lower canopy 11 is tightly fitted with the central rod, allowing it to slide along its axial direction. When the umbrella is opened, the sliding sleeve 111 slides upward, thereby causing the locking sleeve 112, which is fitted outside the sliding sleeve 111, to move upward together until the locking part 1121 and the buckle part 102 automatically engage, achieving a stable lock on the umbrella in the open state. When the umbrella is closed, the sliding sleeve 111 slides downward, avoiding the notch 103 to ensure that the unlocking part 1112 can pass smoothly. When the unlocking part 1112 moves downward until it abuts against the locking part 1121, it pushes the locking part 1121 outward, unlocking the locking part 1121 from the buckle part 102. The sliding sleeve 111 continues to drive the locking sleeve 112 downward, separating it from the upper canopy 11, thus achieving the effect of convenient umbrella closure.

[0043] Since the locking part 1121 and the buckle part 102 are axially engaged, when subjected to external force, the force is transmitted along the axis, avoiding lateral and radial separation forces. This allows the umbrella to remain stable when subjected to external impact and is not easily loosened by external forces such as wind.

[0044] Furthermore, since the locking sleeve 112 is provided with a travel limit part 1122 to restrict the axial sliding of the sliding sleeve 111, it can ensure that the sliding sleeve 111 slides within a certain travel range, preventing excessive movement of the sliding sleeve 111 that could cause structural damage, while also improving safety. When the sliding sleeve 111 slides downwards to the bottom of the travel limit part 1122, the relative position of the sliding sleeve 111 and the locking sleeve 112 is fixed. Therefore, the unlocking part 1112 always abuts against the locking part 1121, ensuring that the locking part 1121 is opened. At this time, if the sliding sleeve 111 continues to slide downwards, it can drive the locking sleeve 112 downwards, thus smoothly separating it from the upper nest 10 and achieving rapid umbrella closure. Similarly, when the sliding sleeve 111 slides upwards to the top of the travel limit part 1122, it can drive the locking sleeve 112 upwards, achieving umbrella opening.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the latching part 102 is a latching tooth, and the locking part 1121 is a latching groove or a latching hole; or, the latching part 102 is a latching groove or a latching hole, and the locking part 1121 is a latching tooth. In a preferred embodiment, the latching part 102 is an outwardly protruding latching tooth, the locking part 1121 is a latching hole, and the bottom surface of the latching tooth is provided with a guide slope. When the locking part 1121 approaches the latching part 102, the guide slope allows the latching tooth to gradually enter the latching hole without applying excessive force, thus achieving a smooth and stable engagement.

[0046] In this embodiment, the locking part 1121 is made of an elastic material. When the unlocking part 1112 moves downward to abut against the locking part 1121, the locking part 1121 expands outward under the elastic force, thus unlocking. At the same time, when the sliding sleeve 111 slides upward to separate the unlocking part 1112 from the locking part 1121, the elastic locking part 1121 can quickly return to its original shape to facilitate engagement with the snap-fit ​​part 102 and ensure good locking performance even after multiple uses.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the unlocking part 1112 is a protrusion structure with protrusions on the outer and inner sides. The protrusion structure increases the contact area. The inner protrusion of the protrusion structure can be provided with a slope to ensure that the protrusion structure can smoothly pass through the avoidance notch 103 when the sliding sleeve 111 is pulled down. At the same time, during the sliding sleeve 111's downward movement, the inner protrusion of the protrusion structure can abut against the outer wall of the upper socket 10, thereby opening the locking part 1121 to a greater extent and making the locking sleeve 112 disengage more smoothly. In a preferred embodiment, two protrusion structures are provided, and the two protrusion structures are symmetrically distributed to ensure balanced force during unlocking. During the sliding process, they abut against the locking part 1121, generating an outward pushing force, so that the latching part 102 and the locking part 1121 can be smoothly separated.

[0048] In addition, the protrusion structure overlaps with the end face of the locking part 1121 when the locking part 1121 and the latching part 102 are engaged, further preventing the sliding sleeve 111 from sliding down when the locking part 1121 and the latching part 102 are engaged, thus ensuring stability.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, the travel limiting part 1122 is a groove provided on the inner side of the locking sleeve 112, and the outer side of the sliding sleeve 111 is provided with a limiting protrusion 1111 that slides axially within the groove. The cooperation between the groove and the limiting protrusion 1111 can precisely control the movement range of the sliding sleeve 111, ensuring that the sliding sleeve 111 moves smoothly within the specified travel range and avoiding structural damage due to excessive sliding. At the same time, when the limiting protrusion 1111 moves to the bottom of the groove, the relative position of the sliding sleeve 111 and the locking sleeve 112 is fixed. Therefore, the unlocking part 1112 always abuts against the locking part 1121, and the locking part 1121 is opened. If the sliding sleeve 111 continues to slide down, it can drive the locking sleeve 112 to slide down and thus smoothly separate from the upper socket 10, ensuring a smooth unlocking process. Similarly, when the sliding sleeve 111 slides upward until the limit protrusion 1111 is stopped by the top of the travel limit part 1122, it can drive the locking sleeve 112 to slide upward, thereby opening the umbrella.

[0050] like Figure 1 and Figure 2 As shown, in this embodiment, a first pivot groove 104 is provided on the outer side of the upper nest 10, and a second pivot groove 113 is provided on the outer side of the locking sleeve 112. The first pivot groove 104 and the second pivot groove 113 are used to fix the umbrella frame. The umbrella frame is connected to the middle notch of the pivot groove, and the end of the umbrella frame can be provided with a protruding part that fits tightly with the notch. The protruding part is inserted into the notch of the pivot groove and fixed by a fastener. The fastener can be a wire or a buckle.

[0051] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, one end face of the upper nest 10 is provided with a cavity structure 101 for accommodating the umbrella's central rod, and the other end face of the upper nest 10 is provided with a threaded hole 105 extending through the cavity structure 101. The threaded hole 105 can be used to install other components (such as top decorations or other accessories). Through the threaded connection, these components can be more firmly fixed to the top surface of the upper nest 10 of the umbrella, preventing the components from loosening or falling off due to external forces or wind during use.

[0052] like Figure 2 and Figure 4 As shown, in this embodiment, the other end of the sliding sleeve 111 is provided with a radially extending stepped portion 1113 and a handle portion 1114 for hand gripping. The stepped portion 1113 is located between the handle portion 1114 and the locking sleeve 112. The sliding sleeve 111 slides upward until the stepped portion 1113 is in contact with the locking sleeve 112, thereby facilitating the upward movement of the locking sleeve 112, so that the buckle portion 102 and the locking portion 1121 are engaged. The umbrella can be automatically opened and closed by a motor and cable, or it can be manually operated by the handle portion 1114 to switch between opening and closing, allowing the user to easily complete the locking and unlocking process.

[0053] like Figure 2 As shown, in this embodiment, a concave annular groove 1115 is provided between the handle portion 1114 and the step portion 1113. The design of the concave annular groove 1115 allows the user to grip the handle portion 1114 more naturally, and the fingers can find a suitable grip position in the annular groove 1115, providing better control during operation.

[0054] Example 2

[0055] An umbrella includes the umbrella canopy structure described in Embodiment 1. Through optimized structural design, it offers convenient opening and closing operations and ensures the stability of the umbrella during use, thereby improving the user experience.

[0056] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
