Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a circular handrail inwardly connected top L-shaped elbow. Background Art

[0002] In modern architectural design, handrails are not only an important component of safety protection, but also a key element of indoor or outdoor decoration. Traditionally, the elbows of handrails are usually installed directly on the inner and outer surfaces of aluminum alloy plates. Although this design is simple and easy to implement, it also has many problems. First, exposed screws are easily affected by the external environment, such as rust and wear, which can cause loosening or even falling off, posing a safety hazard to users. Second, exposed screw holes and screw marks seriously affect the overall aesthetics of the handrail. In addition, in some high-end occasions or places with high aesthetic requirements, such designs often fail to meet customer needs.

[0003] In recent years, with the improvement of people's living standards and the pursuit of a higher quality of life, the requirements for architectural details have become increasingly stringent. A variety of improved handrail elbow designs have appeared on the market, but many products still fail to effectively address the aforementioned issues. Therefore, the development of a new handrail elbow that is both safe and reliable and has a good visual effect is particularly urgent. Utility Model Content

[0004] The purpose of the utility model is to provide a circular handrail inner-connected top L-shaped elbow which has a reasonable structure, is safe and reliable, is easy to install and has a beautiful appearance.

[0005] The present application discloses an L-shaped elbow with an inward-connected top end of a circular handrail, which mainly includes an elbow body. A protruding joint is provided at one end of the elbow body. The joint gradually becomes smaller from the end close to the elbow body to the outside, and no welding, screws or other fastening are required during installation.

[0006] To further describe the above solution, the elbow body is L-shaped like a circular tube, and the diameter of the elbow body is greater than or equal to the diameter of the handrail connected to it, ensuring that the connection is smooth and beautiful.

[0007] On the basis of the above-mentioned solution, the joint extends into the interior of the elbow body to form a reinforcing rib, thereby ensuring a more stable connection and increasing the service life of the entire elbow.

[0008] Preferably, the cross-section of the joint is rectangular, with raised wedge surfaces on all sides, allowing the elbow to more firmly clamp the handrail to prevent sliding or falling off. A circular through-hole is opened in the center of the joint to ensure that it can withstand a certain amount of deformation when squeezing the wedge surface during installation.

[0009] Compared with the prior art, the present invention has the following significant advantages:

[0010] Enhanced Safety: By completely concealing the joints within the handrail, safety hazards caused by loose screws are avoided. At the same time, the rib design further enhances the strength of the connection, ensuring structural stability during long-term use.

[0011] Beautiful and elegant: Since all the fixings are cleverly hidden, the entire handrail looks more concise and smooth, without obvious screw marks, which greatly improves the overall appearance quality and is particularly suitable for application needs in high-end places.

[0012] Easy to install and maintain: Despite the complex internal structure design, the actual installation process is not complicated and the operation is simple and quick. If repairs or replacements are needed, it is also very convenient without damaging the original wall or other components.

[0013] Wide range of applications: This elbow is suitable for circular tubular handrails of different diameters made of various materials (such as stainless steel, aluminum), and is widely used in stairs, balcony guardrails, public facilities and other fields. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] See also Figure 1-Figure 5 As shown, the present invention provides a circular handrail-connected top L-shaped elbow, comprising an elbow body 1 with a protruding connector 2 at one end. The connector 2 tapers outward from the end closest to the elbow body 1, eliminating the need for welding, screws, or other fastening during installation. In this embodiment, the elbow body 1 is tubular and L-shaped, and its diameter is equal to or greater than the diameter of the handrail 4 to which it is connected, ensuring a smooth and aesthetically pleasing connection.

[0026] like Figure 2 As shown, the joint 2 extends into the interior of the elbow body 1 to form a reinforcing rib 22, which ensures a more stable connection and increases the service life of the entire elbow.

[0027] like Figure 1 、 2 As shown, the cross section of the joint 2 is rectangular, with raised wedge surfaces 21 on all sides, allowing the elbow to more firmly clamp the handrail 4 to prevent sliding or falling off. A circular through hole is opened in the center of the joint 2 to ensure that it can withstand a certain amount of deformation when squeezing the wedge surface 21 during installation.

[0028] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, its principle is further explained below in combination with the usage method.

[0029] like Figure 3 、 4 As shown in Figure 5, the end of the handrail 4 is equipped with an interface 41 that matches the connector 2 of the elbow body 1. When installing, align the connector 2 with the interface 41, use some buffering materials such as rotten clothes to abut the elbow body 1, and then knock the elbow body 1 to knock the connector 2 into the interface 41 of the handrail 4. After installation, Figure 4 、5 As shown, the other end of the elbow body 1 is against the wall 23. Since all the fixing parts are cleverly hidden, the entire handrail looks more simple and smooth, without obvious screw marks, which greatly improves the overall appearance quality.
