DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application claimed, but merely represents selected embodiments of the application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0033] Reference should be made to Figures 1-3 The embodiment provides a wasp nest 3 locking structure, comprising: a middle rod 1, two limiters 2, a nest 3 and a ring-shaped buckle 4; the two limiters 2 are arranged axially along the middle rod 1, the end portions of the two limiters 2 are provided with guide inclined surfaces 21, and the outer periphery of the limiter 2 is provided with a locking groove 22; the nest 3 is an integral molding structure, is slidably sleeved on the middle rod 1 and is provided with a limiting groove 31 matched with the limiter 2; the ring-shaped buckle 4 is elastically clamped on the nest 3 and sleeved on the middle rod 1 through a clamping structure, the inner side of the ring-shaped buckle 4 is provided with a radially protruding locking block 41, the buckle can axially slide along the middle rod 1 and has a radial elastic expansion and contraction degree of freedom; when the nest 3 moves axially along the middle rod 1, the guide inclined surface 21 and the locking block 41 are radially extruded, driving the buckle to produce radial displacement until the locking block 41 is clamped into the locking groove 22.

[0034] Since the limiters 2 and the nest 3 are locked through the cooperation of the guide inclined surfaces 21 and the locking block 41, when the locking block 41 is clamped into the locking groove 22, a stable locking state can be provided, and the position of the nest 3 can be well fixed when the umbrella is opened or closed, effectively preventing the nest 3 from accidentally sliding on the middle rod 1. Moreover, the nest 3 is an integral molding structure, which reduces the complex assembly steps, reduces the assembly cost, and improves the use stability of the nest 3 when assembling with the middle rod 1, the limiter 2 and the ring-shaped buckle 4.

[0035] In addition, the nest 3 of the embodiment is integrated with a ring-shaped buckle 4, which has a radial elastic expansion and contraction degree of freedom along the middle rod 1, that is, the radial movement of the locking block 41 relative to the middle rod 1 can be achieved by pressing the ring-shaped buckle 4. Therefore, when in use, the nest 3 can be separated from the limiter 2 by pressing the ring-shaped buckle 4 to make the locking block 41 disengage from the locking groove 22, and the opening or closing of the umbrella can be achieved by pushing the nest 3 up or down. In this way, the opening or closing mechanism of the umbrella is integrated on the nest 3, which greatly simplifies the mechanism for controlling the opening and closing of the umbrella, making the use of the umbrella more convenient. When the ring-shaped buckle 43 is unlocked and separated from the limiter 2, the pressure applied to the ring-shaped buckle 43 can be released, and at this time the locking block 41 will move to fit the middle rod 1 until it recontacts the guide inclined surface 21.

[0036] In the embodiment, the honeycomb 3 is provided with a through hole 32, the middle rod 1 is inserted into the through hole 32, the inner side wall of the through hole 32 is provided with a mounting groove 33, and the annular buckle ring 4 is clamped in the mounting groove 33. The honeycomb 3 has a cylindrical structure as a whole, the through hole 32 penetrates the honeycomb 3, the upper end of the honeycomb 3 is provided with a groove for fixing the umbrella rib, and the outer circumferential side of the honeycomb 3 is provided with a plurality of stripe grooves which can be used for anti-skid and decoration. The shape of the through hole 32 can be designed according to the shape of the limiting piece 2, that is, the limiting groove 31 can be part of the through hole 32. The shape of the mounting groove 33 is matched with the annular buckle ring 4, and the mounting groove 33 surrounds the inner side wall of the through hole 32.

[0037] The through hole 32 can ensure that the honeycomb 3 can slide along the axis of the middle rod 1, and the mounting groove 33 can position and limit the annular buckle ring 4, so that the annular buckle ring 4 can be accurately installed to the predetermined position during assembly and avoid being separated from the honeycomb 3. The through hole 32 and the mounting groove 33 make the assembly of the components more orderly.

[0038] In the embodiment, the inner side wall of the mounting groove 33 is further provided with an extension groove 34 which extends outward along the radial direction of the middle rod 1, and the outer side of the annular buckle ring 4 is provided with a buckle 43 which is clamped in the extension groove 34. The extension groove 34 extends to the end of the honeycomb 3 away from the groove, which facilitates mold forming. The extension groove 34 and the mounting groove 33 form a stepped structure, that is, they have a certain depth difference, the buckle 43 has a triangular structure, and the annular buckle ring 4 itself has a certain deformability, that is, the annular buckle ring 4 can be deformed by extruding opposite sides of the annular buckle ring 4, so that the buckle 43 can be inserted into the mounting groove 33 and the extension groove 34.

[0039] The clamping design of the extension groove 34 and the buckle 43 further strengthens the fixation of the annular buckle ring 4 in the honeycomb 3. When the umbrella is opened or closed, the buckle 43 clamped in the extension groove 34 can effectively prevent the annular buckle ring 4 from accidentally moving in the radial direction. Moreover, the clamping of the buckle 43 and the extension groove 34 can provide clear assembly instructions for the assembly workers during assembly, ensuring the accuracy of assembly.

[0040] The side wall of the honeycomb 3 in the embodiment is provided with a positioning hole 35 which communicates with the mounting groove 33, the positioning hole 35 is provided with a button 5 which is connected with the annular buckle ring 4, and the button 5 is opposite to the lock block 41. The button 5 and the annular buckle ring 4 can be an integrally formed structure.

[0041] A button 5 is arranged in the positioning hole 35 and opposite to the lock block 41, and is connected with the annular buckle 4, which provides great convenience for the user to operate the opening and closing of the umbrella. When the user wants to open or close the umbrella, he only needs to press the button 5 to easily change the locking state of the lock block 41 and the lock slot 22. Since the button 5 is arranged in the positioning hole 35 and opposite to the lock block 41, the operation of the button 5 is targeted. Only when the user accurately presses the button 5, the locking state of the lock block 41 can be affected. This helps to prevent the locking structure of the umbrella from being accidentally unlocked or locked due to accidental touch during normal use, ensuring the stability and safety of the umbrella during use.

[0042] In the embodiment, the clamping structure includes a mounting column 42 arranged on the outer side of the annular buckle 4 and opposite to the lock block 41, and a resilient member (not shown in the figure) sleeved on the mounting column 42, one end of the resilient member abutting against the annular buckle 4 and the other end abutting against the inner wall of the mounting groove 33. The resilient member is a metal spring.

[0043] The resilient member in the clamping structure can provide a continuous and stable locking force, and the elastic force of the resilient member helps to maintain the close clamping state of the lock block 41 and the lock slot 22 when the lock block 41 is clamped into the lock slot 22. When the umbrella is opened or closed, whether it is slightly shaken or pulled by a certain degree of external force, this stable locking force can ensure the position of the honeycomb 3 on the middle rod 1 fixed, preventing accidental unlocking.

[0044] Please refer to Figure 1 As a first embodiment, the limiting member 2 is a flat block, the lock slot 22 is located on the surface of the flat block, and the flat block is provided with a guide inclined surface 21 on both ends in the axial direction of the middle rod 1. Since the limiting groove 31 can be part of the through hole 32, the shape of the through hole 32 in this embodiment is a combination of a circular hole matched with the middle rod 1 and a hole matched with the flat block.

[0045] The flat block has two symmetrically arranged guide inclined surfaces 21, which can facilitate the installation and disassembly of the honeycomb 3, that is, the flat block does not need to be removed when disassembling or assembling the honeycomb 3. The flat block can also further limit the honeycomb 3. When the honeycomb 3 is clamped on the flat block, on the one hand, it can be limited by the lock slot 22 to avoid sliding along the axial direction of the middle rod 1; on the other hand, the two sides of the flat block can also limit the honeycomb 3 to avoid rotating relative to the middle rod 1, which can further improve the stability of the honeycomb 3 in cooperation with the fixation of the umbrella rib.

The shape of the perforation 32 in this embodiment is matched with the shape of the cuboid block 6, and at this time, the perforation 32 and the limiting groove 31 are the same structure.

[0047] The cuboid block 6 as the limiting member 2 has good structural stability in the shape. When various forces in the use process of the umbrella are borne, the structure of the cuboid can uniformly disperse stress, reduce the possibility of local deformation or damage, help to ensure the long-term reliability of the locking structure, and prolong the service life of the umbrella.

[0048] It should be noted that when the limiting member 2 is a rectangular block, the edges of the cuboid block 6 are all provided with arc-shaped transition corners. The edges of the cuboid block 6 are all provided with arc-shaped transition corners, which can effectively avoid the edges causing scratches to the user or the assembly worker during the assembly, use or maintenance of the umbrella, and improve the use safety.

The shape of the perforation 32 in this embodiment is matched with the shape of the cylindrical block 6, and at this time, the perforation 32 and the limiting groove 31 are the same structure.

[0050] The cylindrical block 7 has good adaptability in space, can form a relatively harmonious spatial relationship with the middle rod 1 and the honeycomb 3, and compared with other shapes of the limiting member 2, the cylindrical shape will not produce sharp corners to interfere with other components, which is beneficial to realize efficient layout in limited space.
