[0001] This application relates to the field of connection structures, and more particularly to a telescopic connection structure and a human body pillow. Background Technology

[0002] In many fields such as machinery manufacturing, building assembly, and furniture production, the connection and fixation between components are crucial for realizing product functionality. Telescopic connection structures, with their ability to flexibly adjust connection lengths and adapt to different assembly requirements, have gained widespread application. For example, in furniture assembly, telescopic connection structures can easily adjust the spacing between components, improving installation efficiency.

[0003] However, existing telescopic connection structures lack reliable expansion mechanisms and have limited fixing methods. Under external impact or long-term vibration, the fixing columns are prone to loosening or even falling off, reducing the service life and safety of the connection structure. Furthermore, in most connection structures, the fit between the elastic structure and the fixing column is not tight enough, making it difficult to effectively transfer loads and meet the requirements of complex working conditions. Therefore, a new telescopic connection structure is urgently needed to solve the problems of unstable connections and poor adaptability in existing technologies. Utility Model Content

[0038] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] To address the aforementioned technical problems, this application provides a telescopic connection structure for the stable connection and positioning of components.

[0040] Please see Figures 1-7 The telescopic connection structure provided in this application includes:

[0041] The main body 01, the fixing post 02, the mounting hole 03 and the elastic structure 04 are provided. The mounting hole 03 is provided on the main body 01. The fixing post 02 is telescopically sleeved in the mounting hole 03. The elastic structure 04 is provided on the main body 01. The fixing post 02 is provided with a limiting part. The elastic structure 04 is used to cooperate with the limiting part through elasticity and limit the fixing post 02 to a predetermined position on the mounting hole 03.

[0042] The main body 01 is provided with mounting holes 03, and the fixing post 02 is fitted into the mounting holes 03. The elastic structure 04 is installed on the main body 01 and corresponds to the limiting part on the fixing post 02. In the initial state, the fixing post 02 may be in a retracted or extended position, and the elastic structure 04 is in a natural state or has a certain preload.

[0043] Specifically, when it is necessary to extend the fixed post 02, an outward pulling force is applied to the fixed post 02. At this time, the limiting part on the fixed post 02 interacts with the elastic positioning part 041 of the elastic structure 04. When the elastic positioning part 041 is subjected to the external force brought about by the movement of the fixed post 02, it undergoes elastic deformation, generating elastic force. As the fixed post 02 extends, the elastic positioning part 041 is gradually compressed or deformed. When the fixed post 02 reaches the predetermined extension position, the elastic positioning part 041, under the action of its own elastic restoring force, embeds itself into the corresponding limiting groove on the fixed post 02. At this time, the elastic positioning part 041 and the limiting groove are tightly fitted, and the friction and clamping force generated by the elastic force restrict the fixed post 02 to this extension position, preventing it from automatically retracting.

[0044] When it is necessary to retract the fixed post 02, an inward thrust is applied to the fixed post 02, so that the elastic positioning part 041, under the action of its own elastic restoring force, is embedded in the corresponding limiting groove on the fixed post 02, thereby restricting the fixed post 02 to the retracted position.

[0045] By inserting the fixing post 02 into the mounting hole 03, a fixed connection between components is achieved. Combined with the tight fit between the elastic structure 04 and the fixing post 02, a multi-layered and stable connection is formed compared to the traditional single fixing method. When faced with external impact or long-term vibration, the fixing post 02 is not easy to loosen or fall off, which enhances the stability and reliability of the connection structure and extends its service life. In addition, the connection method of inserting the fixing post 02 into the mounting hole 03 is simple to operate, facilitates the quick connection and fixation between components, improves assembly efficiency, and reduces labor costs.

[0046] In an optional embodiment, the elastic structure 04 includes an elastic positioning part 041 and a mounting part 042, the elastic positioning part 041 and the mounting part 042 are fixedly connected, and the mounting part 042 is fixedly mounted on the main body 01.

[0047] In this embodiment, the elastic positioning part 041 is made of high-strength metal wire with good elastic recovery performance, and the mounting part 042 is made of engineering plastic injection molding. High-strength metal wire and durable engineering plastic are selected as the materials of the elastic structure 04. These materials have good elastic recovery performance and fatigue resistance, ensuring that the elastic structure 04 is not easily damaged during long-term use.

[0048] Specifically, the mounting part 042 is also provided with a slot 012. The shape and size of the slot 012 match the end of the elastic positioning part 041. By embedding the end of the elastic positioning part 041 into the slot 012, the elastic positioning part 041 and the mounting part 042 are fixedly connected.

[0049] In an optional embodiment, the elastic positioning part 041 is a protruding structure and the limiting part is a limiting groove. When the fixing post 02 extends or retracts to a specific position, the protruding structure is embedded in the limiting groove under elastic action.

[0050] Based on any of the above embodiments, the bent elastic positioning part 041 further forms a protruding structure. This protruding structure has a certain elastic deformation capability, can undergo elastic deformation and store energy when subjected to force, and can quickly return to its original shape when the external force disappears. The protruding structure is shaped like a smooth hemispherical shape. The smooth surface reduces the friction when in contact with the limiting part of the fixing post 02, and at the same time avoids scratching the surface of the fixing post 02.

[0051] The fixed column 02 is provided with a limiting part. In this embodiment, the limiting part is a limiting groove. Through the cooperation of the protruding structure and the limiting groove, the fixed column 02 is accurately positioned to avoid the fixed column 02 from becoming loose or displaced.

[0052] When the fixed post 02 extends or retracts, the protruding structure of the elastic positioning part 041 undergoes elastic deformation as the fixed post 02 moves. When the fixed post 02 extends or retracts to a specific position, the protruding structure quickly returns to its original shape under its own elastic action and embeds into the corresponding limiting groove, thereby completing the extension or retraction of the fixed post.

[0053] In an optional embodiment, the limiting groove includes a first limiting groove 05 and a second limiting groove 06; when the fixing post 02 is in the extended position, the protruding structure cooperates with the first limiting groove 05; when the fixing post 02 is in the retracted position, the protruding structure cooperates with the second limiting groove 06.

[0054] Based on any of the above embodiments, the limiting groove further includes a first limiting groove 05 and a second limiting groove 06. Both the first limiting groove 05 and the second limiting groove 06 are formed on the surface of the fixed post 02, and are both processed by precision milling, with smooth groove wall surfaces to ensure smoothness when the limiting groove and the protruding structure are engaged.

[0055] When the fixing post 02 extends to the extended position, the protruding structure of the elastic positioning part 041 engages with the first limiting groove 05 under elastic action, thereby restricting the fixing post 02 to the extended position. When the fixing post 02 retracts to the retracted position, the protruding structure cooperates with the second limiting groove 06, restricting the fixing post 02 to the retracted position. The depth of the limiting groove is 2-3 mm, and the width is slightly larger than the diameter of the protruding structure, allowing the protruding structure to smoothly engage and disengage.

[0056] In this embodiment, the precision machining and reasonable size design of the limiting groove, as well as its good fit with the protruding structure, reduce mutual wear and improve the durability of the entire telescopic connection structure.

[0057] In an optional embodiment, the fixing post 02 includes a first end and a second end, and the first end and / or the second end is provided with a limiting structure.

[0058] The fixing post 02 in this embodiment includes a first end and a second end. The fixing post 02 is cylindrical in shape and is made of high-strength metal materials such as stainless steel or aluminum alloy to ensure that it has high mechanical strength and corrosion resistance.

[0059] The limiting structure features a simple design, employing common mechanical structures and processing techniques, making it easy to manufacture and install. Meanwhile, the selection of high-strength materials ensures the durability of the limiting structure during long-term use, reducing product maintenance costs.

[0060] In an optional embodiment, the limiting structure on the first end includes a thread disposed on the fixed post 02 and a nut 07 that engages with the thread.

[0061] Based on any of the above embodiments, the limiting structure on the first end further includes a thread on the fixed post 02 and a nut 07 that mates with the thread. The thread is a standard metric thread, and the pitch is determined according to the size of the fixed post 02 and the stress conditions. The nut 07 is a hexagonal nut, the material of which matches the fixed post 02, and the position of the fixed post 02 is locked by rotating the nut 07.

[0062] The nut 07 provided on the first end of the fixed column 02 is used to prevent the fixed column 02 from dislodging from the mounting hole 03 when the fixed column 02 is adjusted in position by telescoping.

[0063] In an optional embodiment, the limiting structure on the second end includes a pile head 08 disposed on the fixed post 02, the diameter of the pile head 08 being larger than the diameter of the mounting hole 03.

[0064] The limiting structure on the second end includes a pile head 08 mounted on the fixed post 02. The pile head 08 is integrally formed with the fixed post 02 by forging or machining. The diameter of the pile head 08 is larger than the diameter of the mounting hole 03, forming a blocking structure. When the fixed post 02 is inserted into the mounting hole 03, the pile head 08 is locked outside the mounting hole 03, preventing the fixed post 02 from coming out of the mounting hole 03 and ensuring the stability of the fixed post 02 during use.

[0065] In an optional embodiment, an accessory is also included, which is connected to the fixing post 02.

[0066] In this embodiment, the accessories are designed in various types according to actual usage needs, including but not limited to brackets and hangers. The accessories are made of lightweight yet high-strength materials, such as engineering plastics or aluminum alloys, to reduce overall weight while ensuring structural strength, making them easy for users to use and carry. The connection positions between the accessories and the fixing post 02 are rationally arranged according to the overall structure and usage requirements of the human pillow.

[0067] In an optional embodiment, the connection between the accessory and the fixed post is a detachable connection.

[0068] The detachable connection method allows accessories to be replaced or adjusted at any time according to user needs, and facilitates the use of accessories with different functions in different scenarios, improving the flexibility of the body pillow. When an accessory is damaged, it is not necessary to replace the entire body pillow; only the damaged accessory needs to be replaced, reducing usage costs and resource waste.

[0069] In an optional embodiment, the accessory includes a connecting buckle 09 and a strap 010. The strap 010 is connected to the connecting buckle 09. The connecting buckle 09 is provided with a connecting port and a first through hole 091. When the connecting buckle 09 is connected to the fixing post 02, the fixing post 02 is inserted into the connecting port, and the strap 010 passes through the first through hole 091 and is connected to the connecting buckle 09.

[0070] Based on any of the above embodiments, the connecting buckle 09 is further made of high-strength and elastic polycarbonate material, integrally molded by injection molding. The connecting buckle 09 is triangular, and the connection port on the connecting buckle 09 that connects to the fixing post 02 is a circular through hole 092. The diameter of the through hole 092 is customized according to the outer diameter of the fixing post 02, and is larger than the diameter of the fixing post 02, so that the fixing post 02 can be easily inserted into the circular through hole 092, ensuring that the fixing post 02 can be easily inserted and maintain a tight fit after being inserted, avoiding loosening. A ring of anti-slip texture is provided on the inner wall of the connection port to increase the friction between the connecting buckle 09 and the fixing post 02 and enhance the connection stability.

[0071] Meanwhile, the strap 010 is an elastic strap. The elastic strap is connected to the connecting buckle 09 through the first through hole 091, thereby fixing the elastic strap to the component. The elastic strap is made of a blend of highly elastic natural rubber and polyester fiber, and the surface is treated with micro-textured material to enhance the friction with the contacting object.

[0072] The high elasticity of elastic straps allows them to adapt to external objects of different shapes and sizes, providing a stable clamping force through their own elastic deformation.

[0073] In an optional embodiment, a groove 011 is provided at the opening of the mounting hole 03 near the second end, and the position of the groove 011 is aligned with the position of the limiting structure at the second end.

[0074] Based on any of the above embodiments, a groove 011 is further provided at the opening of the mounting hole 03 near the second end, and the position of the groove 011 is aligned with the position of the limiting structure at the second end. The width of the groove 011 is slightly larger than the diameter of the pile head 08. When the fixing column 02 is installed in place, the pile head 08 is partially embedded in the groove 011, further enhancing the stability of the fixing column 02, and also facilitating the removal of the fixing column 02. By using the groove 011 to hold the pile head 08, the fixing column 02 can be pulled out. In addition, with the pile head 08 partially embedded in the groove 011, the fixing column 02 and other components on the main body 01 are all on the same horizontal plane.

[0075] In an optional embodiment, the elastic structure 04 is formed by bending a metal wire.

[0076] The diameter of the metal wire is set at 1.2-1.5 mm to ensure both sufficient elastic deformation capacity and structural strength. Using a CNC bending machine, the metal wire is bent into a preset geometric shape to form an elastic positioning part 041 with a specific curvature and protrusion. The elastic structure 04 formed by bending the metal wire is compact in size. By precisely controlling the bending shape of the metal wire and the size of the limiting groove, accurate positioning of the fixing post 02 in the extended and retracted positions can be achieved.

[0077] In an optional embodiment, the positioning part is disposed on both sides of the mounting hole 03, and a second through hole 013 is provided on both sides of the mounting hole 03, with the positioning part protruding from the second through hole 013.

[0078] In this embodiment, the positioning parts of the elastic structure 04 are symmetrically arranged on both sides of the mounting hole 03, forming a double-sided positioning structure. The mounting hole 03 on the main body 01 is used for the telescopic movement of the fixing post 02, and its diameter is designed according to the size of the fixing post 02 to ensure that the fixing post 02 can telescopically move smoothly. Second through holes 013 are symmetrically opened on both sides of the mounting hole 03, and the second through holes 013 are adapted to the positioning parts. The edges of the second through holes 013 are finely polished to prevent wear during the movement of the positioning parts.

[0079] The positioning part is fixedly connected to the main body 01 through a special installation process. Specifically, the bottom of the positioning part is fixed to the main body 01 by welding or high-strength bonding. During installation, ensure that the positioning part protrudes accurately from the second through hole 013 and that the positioning parts on both sides are at the same horizontal height. When the fixing post 02 is inserted into the mounting hole 03, the positioning parts on both sides simultaneously cooperate with the limiting grooves on the fixing post 02, limiting the fixing post 02 from both sides and preventing the fixing post 02 from moving axially or radially within the mounting hole 03.

[0080] This application provides a human pillow, including: a human pillow body and... Figures 1 to 7 The telescopic connection structure is provided on both sides of the main body of the human pillow. (This is one of the embodiments described above.)

[0081] The human pillow provided in this embodiment includes a main body and a telescopic connecting structure. The main body of the human pillow adopts an ergonomic design, using soft and supportive materials to conform to the curves of the neck and head, providing comfortable support for the user. The telescopic connecting structure is located on both sides of the main body of the human pillow.

[0082] The telescopic connection structure is securely connected to the main body of the human body pillow through a specific installation method. For example, an embedded installation method is used, with mounting grooves reserved on both sides of the main body of the human body pillow, into which the fixing components of the telescopic connection structure are embedded.

[0083] The telescopic connection structure also includes accessories that connect to the fixing post 02. The accessories include a connecting buckle 09 and a strap. The strap is elastic and its length can be adjusted according to actual needs, making it convenient for users to fix the pillow in different positions, such as on a chair back or bedside, increasing the flexibility and adaptability of the pillow's use.
