Description

Technical Field

[0001] This application relates to the field of umbrella parts technology, and in particular to an umbrella and its shaft guide anti-rotation structure. Background Technology

[0002] Umbrellas are one of the most common tools in people's daily lives. They not only protect against rain but also provide shade and wind protection in hot or windy weather. Different angles of rain and sunlight necessitate adjusting the umbrella handle to tilt the canopy. However, holding the umbrella at an angle for extended periods can cause hand fatigue. Therefore, to better meet these needs, a design was developed that allows for a change in the canopy angle by rotating the umbrella shaft while keeping the handle angle constant. This design incorporates an angle-adjusting component within the shaft, enabling tilting of the canopy without changing the handle angle, unlike a fixed, one-piece shaft.

[0003] For example, document CN202320327075.5 discloses a simple fishing umbrella bend. Addressing the issue that existing traditional fishing umbrellas cannot adjust the angle, it proposes the following solution: It includes a steering component, with a first rivet passing through its interior. A threaded rod passes through the outer wall of the first rivet, and the threaded rod rotates 180 degrees within the steering component. A second connecting member is fixedly connected to one side of the steering component. A fixing ring and the first connecting member are threadedly connected to the outer wall of the threaded rod, with the fixing ring located between the steering component and the first connecting member. A second rivet passes through the outer wall of the first connecting member.

[0004] The above-mentioned technical solution achieves multi-angle sun protection and rain protection through the umbrella bend. However, when the umbrella surface is tilted, the locking stability between the umbrella surface and the umbrella pole is insufficient, and the specific tilt angle of the umbrella surface is prone to change, which cannot meet the functions of sun protection and rain protection at specific angles.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0060] According to the first aspect of this application, referring to Figures 1 to 9 This disclosure provides an umbrella pole guide anti-rotation structure 100, including: a first body 110, a second body 120, a third body 130, a sliding component 140, a connecting rod 150, and a button 160.

[0061] Reference Figures 1 to 4 The first body 110 includes a convex connector 111 at one end and can be connected to other parts of the umbrella or umbrella pole at the other end. The first body 110 comprises zinc alloy and powder metallurgy material, wherein the convex connector 111 comprises powder metallurgy. Specifically, the convex connector 111 is located at the end of the first body 110 near the second body 120. The convex connector 111 has a plurality of tooth-like structures and a plurality of pool-like structures circumferentially distributed at one end of the first body 110. (Refer to...) Figure 4 The second body 120 is primarily made of powder metallurgy. One end of the second body 120 near the first body 110 has a concave interface 121 corresponding to the convex connector 111. The convex connector 111 and the concave interface 121 can employ a toothed structure that meshes with each other. The other end of the second body 120 away from the first body 110 includes an abutting portion 122. The third body 130 has a receiving cavity 131 and a button through-hole 132. The second body 120 is at least partially disposed within the receiving cavity 131. The maximum circumferential dimension of the second body 120 is the same as the circumferential dimension of the outer surface of the third body 130, while the circumferential dimension of the abutting portion 122 is the same as or slightly smaller than the circumferential dimension of the inner surface of the third body 130, allowing the abutting portion 122 to move relative to the inner surface of the receiving cavity 131.

[0062] The second body 120 is located between the first body 110 and the third body 130, which are connected by a connecting rod 150. One end of the connecting rod 150 has a corresponding threaded hole 151 with the convex connector 111 of the first body 110, and the other end of the connecting rod 150 has a corresponding threaded hole 151 with the first body 110. The connecting rod 150 is connected to the convex connector 111 and the first body 110 by an M6*18 screw. The connecting rod 150 is mainly made of iron.

[0063] A sliding component 140 is disposed within the receiving cavity 131, and is configured to control the second body 120 to be in a locked or unlocked state. A button 160 is disposed within a button through-hole 132, and includes a limiting surface 161. Pressing the button 160 controls the umbrella pole guide anti-rotation structure 100 to be in a locked or unlocked state. When in the unlocked state, the second body 120 can move relative to the first body 110, and the first body 110 can rotate a certain angle in a specific direction relative to the second body 120. When in the locked state, the second body 120 is fixed relative to the first body 110, and the first body 110 cannot continue to rotate relative to the second body 120, thus keeping the first body 110 in a fixed state relative to the second body 120.

[0064] When the umbrella pole guide anti-rotation structure 100 is in the unlocked state, the limiting surface 161 and the sliding component 140 are not in contact. At this time, the sliding component 140 can slide within the receiving cavity 131. Since the second body 120 is connected to the sliding component 140, the second body 120 can slide relative to the third body 130, thereby allowing the first body 110 to rotate relative to the second body 120 at a certain angle. When the umbrella pole guide anti-rotation structure 100 is in the locked state, one end of the sliding component 140 is in contact with the abutment part 122, and the other end is in contact with the limiting surface 161. At this time, both ends of the sliding component 140 are restricted, and the sliding component 140 can no longer slide within the receiving cavity 131. At this time, the second body 120 is also locked, and the first body 110 cannot rotate relative to the second body 120, thereby locking the first body 110.

[0065] In some embodiments, refer to Figure 4 The second body 120 is provided with a hollow connecting through hole 123, and the connecting rod 150 passes through the connecting through hole 123. At this time, the connecting rod 150 is located in the middle part of the umbrella rod guide anti-rotation structure 100 in the circumference. On the one hand, it can improve the connection stability between the first body 110 and the third body 130. On the other hand, it can make full use of the space between the first body 110, the second body 120 and the third body 130, and reduce the overall volume of the umbrella rod guide anti-rotation structure 100.

[0066] In some embodiments, refer to Figure 5 The sliding assembly 140 includes a first slider 141, a second slider 142, and a guide spring 143. The first slider 141 is mainly made of iron, and the second slider 142 is mainly made of aluminum alloy. The first slider 141 contacts the abutment portion 122, and the second slider 142 is located on the side of the first slider 141 away from the abutment portion 122. The second slider 142 has a slider cavity 1421, and the guide spring 143 is at least partially disposed in the slider cavity 1421. One end of the guide spring 143 is connected to the second slider 142, and the other end is connected to the second body 120. When the button 160 is pressed and the umbrella pole guide anti-rotation structure 100 is in the unlocked state, the force generated by rotating the first body 110 will be transmitted sequentially to the second body 120 and the sliding component 140. When the first body 110 rotates to the required angle, under the action of the guide spring 143, the second slider 142 will give way to the movement space of the button 160. At this time, by pressing the button 160, the limiting surface 161 will contact the second slider 142, thus locking the umbrella pole guide anti-rotation structure 100.

[0067] In some embodiments of this application, reference is made to Figures 6 to 9 The button 160 includes a locking part 162 and an unlocking part 163, with a limiting surface 161 located between the locking part 162 and the unlocking part 163. The limiting surface 161 is flat, and the part of the second slider 142 that contacts the limiting surface 161 is also flat. The parts of the second slider 142 that contact the limiting surface 161 also have corresponding inclined surfaces. The flat structure provides stronger support, thus ensuring strong locking of the first body 110 and improving the stability of the umbrella rod guide anti-rotation structure 100 in the locked state.

[0068] In some embodiments of this application, the umbrella pole guide anti-rotation structure 100 further includes a return spring 170, disposed within the receiving cavity 131, with one end connected to the first body 110 and the other end connected to the unlocking part 163. When the unlocking part 163 is pressed to unlock the umbrella pole guide anti-rotation structure 100, the return spring 170 provides a force opposite to the pressing direction to the button 160. When the first body 110 rotates to a specific state, the pressure on the unlocking part 163 of the button 160 is released. Under the action of the return spring 170, the locking part 162 can easily enter a preset position, completing the locking of the umbrella pole guide anti-rotation structure 100. Due to the presence of the return spring 170, the pressing area of ​​the unlocking part 163 is larger than the pressing area of ​​the locking part 162, making the pressing more comfortable when the umbrella pole guide anti-rotation structure 100 is unlocked. The reset spring 170 is set on the lower side of the locking part 162 as needed, making full use of the receiving cavity 131 of the third body 130. At the same time, it makes the entire button 160 have better force balance. When the button 160 is pressed, the force on the unlocking part 163 is relatively more uniform, thus extending the service life of the button 160.

[0069] According to a second aspect of this disclosure, an umbrella is provided, which can be a dual-purpose umbrella, a fishing umbrella, or other types of umbrellas.
