[0022] This utility model proposes a handrail connection structure 1000.

[0023] Please see Figure 1 , Figure 2 as well as Figure 5In one embodiment of this utility model, the handrail connecting structure 1000 connects the horizontal handrail 5 and the vertical handrail 4 respectively. The handrail connecting structure 1000 includes a first connector 1 and a second connector 2. The first connector 1 has a through groove 11, which is configured to fit onto the outside of the vertical handrail 4. The second connector 2 is detachably connected to the first connector 1.

[0025] The handrail connection structure 1000 provided by this utility model solves the problems of inconvenient installation, difficult disassembly, and unstable connection of traditional handrail connection structures 1000 by adopting a detachable connection method of the first connector 1 and the second connector 2. Specifically, the first connector 1 has a through groove 11, which is configured to fit onto the outside of the vertical handrail 4. This design allows the vertical handrail 4 to be firmly fixed in the first connector 1, ensuring the stability of the vertical handrail 4. The second connector 2 is detachably connected to the first connector 1, and the second connector 2 has a notch 21, which is configured to connect with the peripheral wall of the horizontal handrail 5. This design allows the horizontal handrail 5 to fit tightly with the second connector 2, thereby achieving a firm connection between the horizontal handrail 5 and the vertical handrail 4. Through the detachable connection of the first connector 1 and the second connector 2, users can easily install and disassemble the handrail, improving installation efficiency and maintenance convenience. Furthermore, even if the vertical handrail 4 and the horizontal handrail 5 are not connected at a 90-degree angle during actual use, the arc-shaped design of the end of the first connecting piece 1 corresponding to the end connecting the second connecting piece 2, and the arc-shaped design of the end of the second connecting piece 2 corresponding to the end connecting the first connecting piece 1, can accommodate different angle connection requirements between the horizontal handrail 5 and the vertical handrail 4. This connection method can adapt to handrails of different sizes and shapes, avoids the fire risk caused by on-site welding, improves installation efficiency and maintenance convenience, and ensures the stability and reliability of the handrail.

[0026] In one embodiment of the present invention, the first connecting member 1 includes a cylindrical body 12 and a first connecting part 13. The cylindrical body 12 has a through groove 11. The first connecting part 13 is located at one end of the bottom wall of the cylindrical body 12 and is connected to the cylindrical body 12. The first connecting part 13 is arc-shaped and is connected to the second connecting member 2. The cylindrical body 12 is sleeved on the vertical handrail 4.

[0027] In this embodiment, combined with Figure 2To facilitate installation and disassembly, the cylinder 12 has a through groove 11, through which the vertical handrail 4 is fitted into the cylinder 12. The cylinder 12 is a hollow structure, and its outer diameter can be set to approximately 50.5 mm. The distance between the two opposite walls of the through groove 11 is approximately 47.5 mm. The distance between the end of the first connecting part 13 furthest from the cylinder 12 and the end of the first connecting part 13 closest to the cylinder 12 is 33.5 mm. The shape and size of the through groove 11 match the vertical handrail 4, achieving fixation and support of the vertical handrail 4 through a tight fit. The first connecting part 13 is located at one end of the bottom wall of the cylinder 12 and is connected to the cylinder 12. It can be understood that the connection between the first connecting part 13 and the cylinder 12 includes, but is not limited to, threaded connection, snap-fit ​​connection, welding, and can also be connected by integral molding, which can be set according to specific needs. The first connecting part 13 is connected to the second connecting part 2 by bolt connection, screw connection, etc. Furthermore, in order to achieve a tight connection between the cylinder 12 and the vertical handrail 4, fastening holes are also provided on the cylinder 12, and fasteners such as bolts and screws are passed through the fastening holes for fixation.

[0028] In one embodiment of the present invention, the first connecting part 13 includes a first mating section 131 and a first connecting section 132 connected to each other. The first connecting section 132 is connected to the cylinder 12, and the first mating section 131 is connected to the second connecting member 2. The first mating section 131 is arc-shaped, and the first connecting section 132 is square-shaped.

[0029] In this embodiment, combined with Figure 2 and Figure 3 The first mating section 131 is arc-shaped, which effectively increases the contact area, improves the stability and firmness of the connection, reduces stress concentration, and extends service life. Simultaneously, the arc-shaped first mating section 131 can also achieve a certain self-centering function through shape matching, ensuring the accuracy of the connection. The first connecting section 132 is square-shaped and connects to the cylinder 12. The square design provides sufficient structural strength and support, ensuring that the first connecting part 1 will not deform or loosen under external force. The square structure also facilitates processing and installation, forming a stable connection with the cylinder 12. It is understood that even if the vertical handrail 4 and the horizontal handrail 5 are not connected at a 90-degree angle in actual use, the arc-shaped first mating section 131, combined with the arc-shaped second mating section 231 described in the next embodiment, allows the connection of the first mating section 131 and the second mating section 231 to accommodate different angle connection requirements between the horizontal handrail 5 and the vertical handrail 4. At the same time, the curved surface can reduce stress concentration points and avoid damage or loosening of the connection parts due to excessive local stress.

[0030] In one embodiment of the present invention, the second connecting member 2 includes a mounting member 22 and a second connecting part 23. The mounting member 22 has a notch 21. The second connecting part 23 is located at the end of the mounting member 22 away from the notch 21 and is connected to the mounting member 22. The second connecting part 23 is arc-shaped and is connected to the first connecting member 1. The mounting member 22 is connected to the crossbar handrail 5.

[0031] In this embodiment, combined with Figure 2 and Figure 5 The mounting component 22 is used to fix the horizontal handrail 5. The mounting component 22 has a notch 21, the shape and size of which match the outer peripheral wall of the horizontal handrail 5. Through the tight fit between the notch 21 and the horizontal handrail 5, the mounting component 22 can firmly fix the horizontal handrail 5, ensuring its stability during use. Due to the design of the notch 21, even if the horizontal handrail 5 is set at an angle in actual use (not a 90-degree connection), the mounting component 22 can still maintain a tight connection with the horizontal handrail 5 through the notch 21, adapting to different angle installation requirements. The second connecting part 23 can withstand the force and torque from the horizontal handrail 5 and the vertical handrail 4, ensuring the stability of the entire connection structure during use. Through a tight connection with the first mating section 131 of the first connecting component 1, the second connecting part 23 can transmit the force of the horizontal handrail 5 to the vertical handrail 4, forming a stable connection system. It is understood that the connection relationship between the mounting component 22 and the second connecting part 23 includes, but is not limited to, welding, bolting, snap-fitting, etc., and can also be connected by integral molding. Furthermore, in order to ensure the connection between the mounting component 22 and the crossbar handrail 5, the mounting component 22 is provided with multiple screw holes along its circumference, and fasteners such as bolts and screws are passed through the screw holes to connect with the crossbar handrail 5.

[0032] In one embodiment of the present invention, the second connecting part 23 includes a second mating section 231 and a second connecting section 232 connected to each other. The second connecting section 232 is connected to the mounting member 22, and the second mating section 231 is connected to the first connecting member 1. The second mating section 231 is arc-shaped, and the second connecting section 232 is square-shaped.

[0033] In this embodiment, combined with Figure 4 To enhance angular adaptability, the second mating section 231 is arc-shaped. This design allows the second connector 2 to fit tightly with the arc-shaped design of the first mating section 131 of the first connector 1. The arc-shaped surface can adapt to different angle changes, reducing connection problems caused by angle deviations. The second connecting section 232 is square-shaped and firmly connected to the mounting part 22. The square shape has high torsional and bending resistance, effectively withstanding the force from the crossbar handrail 5 and ensuring connection stability.

[0034] In one embodiment of this utility model, the inner wall of the notch 21 is arc-shaped.

[0035] In this embodiment, combined with Figure 1 To enhance angle adaptability, the notch 21 of the arc-shaped inner wall can accommodate the installation requirements of the crossbar handrail 5 at different angles. The arc-shaped inner wall can evenly distribute the stress at the connection points, preventing damage or loosening of the connection points due to excessive local stress.

[0036] In one embodiment of the present invention, the handrail connection structure 1000 further includes a fastener 3, which passes through the first connector 1 and is connected to the second connector 2.

[0037] In this embodiment, combined with Figure 1 To facilitate the installation and disassembly of the first connector 1 and the second connector 2, fasteners 3 mechanically and tightly connect the first connector 1 and the second connector 2 together. Common fasteners 3 include bolts, screws, and clips. These fasteners 3 apply preload to ensure that there is no relative movement between the two connectors, thereby improving the stability of the connection.

[0038] In one embodiment of the present invention, the first connector 1 has a first connecting hole 14, the second connector 2 has a second connecting hole 24, and the fastener 3 passes through the first connecting hole 14 and the second connecting hole 24 for fixation.

[0039] In this embodiment, combined with Figures 2 to 4 To enhance the connection strength, fasteners 3 are used to secure the fasteners by passing through the first connecting hole 14 and the second connecting hole 24, ensuring a firm connection between the first connecting member 1 and the second connecting member 2, significantly improving the connection strength and preventing loosening or detachment. It is understood that the type of fastener 3 can be bolts, screws, etc., and is not limited here. In one embodiment, the first connecting hole 14 is circular, and the shape of the second connecting hole 24 is adapted to the shape of the first connecting hole 14. The circular connecting hole can tightly fit with the circular fastener 3 (such as bolts, screws, etc.), ensuring that the fastener 3 can be accurately aligned and firmly fixed during installation. The machining of circular holes is relatively simple and can be easily completed using standard drilling tools, without the need for complex machining processes, thus reducing production costs.

[0040] In one embodiment of the present invention, the first connector 1 includes a cylindrical body 12, and the cylindrical body 12 has a first screw hole 15 that penetrates its inner cavity. The first screw hole 15 is configured to connect with the vertical handrail 4.

[0041] In this embodiment, combined with Figure 3 and Figure 5To enhance the connection strength, the first screw hole 15 penetrates the inner cavity of the cylinder 12, allowing the vertical handrail 4 to be firmly connected to the first connector 1 via screws. This significantly improves the fixing strength of the vertical handrail 4 and prevents it from loosening or falling off. It is understood that the diameter of the first screw hole 15 is approximately 8.5mm.

[0042] In one embodiment of the present invention, the second connector 2 includes a mounting member 22, which has a plurality of spaced second screw holes 25. The second screw holes 25 communicate with the notch 21 and are configured to connect with the peripheral wall of the crossbar handrail 5.

[0043] In this embodiment, combined with Figure 4 and Figure 5 To enhance connection strength, the design of multiple screw holes allows the crossbar handrail 5 to be securely connected to the mounting part 22 via multiple screws, significantly improving the strength and stability of the connection and preventing the crossbar handrail 5 from loosening or falling off during use. The number of second screw holes 25 includes, but is not limited to, 2 or 4. It is understood that the mounting part 22 is arc-shaped, with a second screw hole 25 at each opposite end. The diameter of the second screw hole 25 can be approximately 2.6 mm, and the distance between two adjacent second screw holes 25 is 14.4 mm.
