Description

Technical Field

[0001] The utility model relates to the technical field of parasols, in particular to an umbrella pole connecting structure of a parasol. Background Art

[0002] In order to facilitate transportation, the upright pole of a parasol is usually composed of an upright upper pole and a lower pole that are detachably connected. When not in use, the upper pole and the lower pole can be split into two parts for easy storage and transportation. At present, the detachable installation of the upper pole and the lower pole of the common parasol is mostly a jumping bean spring structure connected after the two poles are sleeved. The jumping beans are metal jumping beans, and the umbrella pole is also made of metal material. During disassembly and assembly, there is contact friction between the jumping beans and the jumping bean holes on the umbrella pole. This contact friction will cause damage to the outer surface of the metal jumping beans, and the corresponding part of the umbrella pole will also be damaged to a certain extent. The metal jumping beans and the corresponding damaged parts of the umbrella pole are exposed. If damaged, these exposed parts will rust, affecting the connection and disassembly, and It is not beautiful; there is a certain gap between the jumping beans and the jumping bean holes. Pressing the jumping beans directly with your hand may pinch the meat, which is unsafe to operate; in addition, in order to facilitate the sleeve installation of the two rods, the outer diameters of the two rods are usually designed to be large and small, so that the rod with a small outer diameter can be directly inserted into the rod with a large outer diameter. From the perspective of strength, the rod with a small outer diameter is slightly weaker than the rod with a large outer diameter. Then, after the whole umbrella pole is connected, there will be a certain impact on the strength of the entire umbrella pole, and the strength of the upper and lower parts will also be inconsistent. Summary of the Invention

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] As shown in the figure, a parasol pole connection structure includes two poles (1, 9) with the same outer diameter, wherein one pole 1 has a coaxially arranged reducing connecting tube 111 that can be inserted into the other pole 9, the reducing connecting tube 111 is sleeved with the corresponding other pole 9 to form a connecting portion L and is connected through a jumping bean spring mechanism, the jumping bean spring mechanism includes a jumping bean 2 and a spring 3, the spring 3 is arranged in the connecting portion L, one end of the jumping bean 2 is a mounting end 21 elastically supported by the spring 3, the other end of the jumping bean 2 is an extending end 22 extending out of the connecting portion L, the outside of the connecting portion L is fully surrounded by a protective shell 4, the extending end 22 is located in the protective shell 4, a snap button 5 is pressably provided on the protective shell 4, one end of the snap button 5 is extended into the protective shell 4 and abuts against the extending end 22, and the other end of the snap button 5 is extended out of the protective shell 4.

[0021] In this specific embodiment, the side of the reduced diameter connecting tube 111 is provided with a first positioning hole 11 for the protruding end 22 to extend out, and the side of the rod body 9 that is sleeved with the reduced diameter connecting tube 111 is provided with a second positioning hole 91 for the protruding end 22 to extend out. After the reduced diameter connecting tube 111 is sleeved with the corresponding rod body 9, the first positioning hole 11 and the second positioning hole 91 are coaxially connected, and the protruding end 22 extends from the first positioning hole 11 and the second positioning hole 91 and is arranged outside the connecting portion L. When the snap button 5 is pressed to move the jumping bean 2 inward and compress the spring 3, the protruding end 22 of the jumping bean 2 only needs to be separated from the second positioning hole 91 provided on the outside to achieve the disassembly between the two rod bodies (1, 9).

[0022] In this specific embodiment, an anti-slip bracket 6 is provided within the reduced diameter connecting tube 111, and the spring 3 is mounted within the anti-slip bracket 6. The anti-slip bracket 6 is provided with an anti-slip mounting hole 61 coaxial with the first positioning hole 11 and the second positioning hole 91. The anti-slip mounting hole 61 allows the protruding end 22 to be extended and mounted. The mounting end 21 is provided with an anti-slip limiter 211. The size of the anti-slip limiter 211 is larger than the inner diameter of the anti-slip mounting hole 61. The protruding end 22 extends from the anti-slip mounting hole 61. The anti-slip limiter 211 is limited within the anti-slip bracket 6. The anti-slip bracket 6 can be used to increase the wall thickness of the connection for mounting the jumping bean 2, which can effectively prevent the jumping bean 2 from entering the rod body as a whole when the user applies pressure on the jumping bean 2, causing it to get stuck and unable to rebound. At the same time, a stable installation position is provided for the spring 3.

[0023] In this embodiment, a spring positioning post 62 is provided within the anti-slip bracket 6. The spring positioning post 62 is positioned opposite the anti-slip mounting hole 61. One end of the spring 3 is mounted on the spring positioning post 62, and the other end of the spring 3 is mounted on the anti-slip stop 211. The spring positioning post 62 ensures a stable installation of the spring 3, preventing it from shifting in position and causing failure of the elastic support.

[0024] In this embodiment, the spring 3 has a V-shaped structure, with insertion portions 31 provided at both ends of the spring 3. The spring positioning column 62 and the mounting end 21 of the jumping bean 2 each have a socket (621, 210) for inserting and installing the corresponding insertion portion 31. The two insertion portions 31 are respectively inserted and installed in the corresponding sockets (621, 210). The structure is simple, easy to install, and stable.

[0025] In this specific embodiment, the anti-dropout bracket 6 is an annular structure, and the anti-dropout bracket 6 is tightly mounted in the reduced diameter connecting pipe 111. The structure is simple, easy to manufacture, and convenient to install and disassemble.

[0026] In this specific embodiment, the protective shell 4 is formed by butting together two half shells 401. A positioning mounting post 402 is provided in the half shell 401. Two positioning mounting holes 10 are provided on the rod body (1, 9). After the two half shells 401 are butted together, the two positioning mounting posts 402 are respectively inserted into one positioning mounting hole 10 and fixedly connected by a connecting member 7. The structure is simple, and a detachable connection and installation between the protective shell 4 and the rod body is achieved, which facilitates the assembly of the various components.

[0027] In this embodiment, the connecting member 7 is a connecting bolt, wherein one positioning and mounting column 402 has a through-hole 403, and the other positioning and mounting column 402 is provided with a matching mounting screw hole 404. The structure is simple, installation and removal are relatively convenient, and the cost is low.

[0028] In this specific embodiment, a crank 8 is provided on the protective shell 4, so that the protective shell 4 can be directly used as a crank shell of a parasol, and one object can be used for multiple purposes.

[0029] In this embodiment, the protective shell 4 and the snap button 5 are both made of plastic, which is low in cost and safer to operate.

[0030] In this specific embodiment, the snap button 5 includes a pressing portion 51 and a limiting portion 52. The protective shell 4 is provided with a snap button mounting hole 46 through which the pressing portion extends. The limiting portion 52 is larger than the inner diameter of the snap button mounting hole 46. The limiting portion 52 is positioned within the protective shell 4 and abuts against the protruding end 22, thereby achieving a stable connection and installation of the snap button 5 on the protective shell 4.
