Description

Technical Field

[0001] This utility model relates to the field of stair handrail connectors, specifically an installation connector that can adapt to different stair handrail tilt angles. Background Technology

[0002] Staircases are structural components used for vertical transportation between floors in buildings. They facilitate movement between floors and when there are significant differences in elevation. Staircases are also necessary in multi-story and high-rise buildings where elevators and escalators are the primary means of vertical transportation. Handrails are an essential component of staircases; they are the supporting bars of the stair railing. Staircase handrails are classified by material as follows: polymer handrails, wrought iron handrails, stainless steel handrails, glass handrails, solid wood handrails, and copper handrails.

[0003] There are many types of stair handrail structures available today. Depending on the angle of inclination of the staircase, the handrail will also tilt at different angles. This necessitates the design of connectors that can be plugged into handrails with different inclination angles. This requires recalibrating the machines to ensure that the inclination angle of the internal plug-in end of the handrail connector is compatible with the site conditions. Alternatively, staircases and handrails with a pre-set inclination angle can be built according to a unified standard. This would allow the use of handrail connectors under the existing standard. However, most renovations nowadays tend to be more personalized, and homeowners must follow the inclination of the staircase they require.

[0004] Based on this, the present invention designs an installation connector that can adapt to different stair handrail tilt angles to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide an installation connector that can adapt to different stair handrail tilt angles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An installation connector adaptable to different stair handrail tilt angles includes a fixed-end mounting plate and a handrail end insertion pipe. The fixed-end mounting plate has hinged side plates installed on both sides of its front end. A hinge shaft is fixedly connected to the tail end of the handrail end insertion pipe. The two ends of the hinge shaft rotatably engage with the hinged side plates on both sides. Welded positioning through holes are provided at both the upper and lower ends of the handrail end insertion pipe. The handrail inserted inside the handrail end insertion pipe is fixed by positioning components passing through the welded positioning through holes at the upper and lower ends.

[0008] As a further embodiment of this utility model, the handrail inserted into the end fitting can also be welded to its upper and lower surfaces by passing through the edge of the welding positioning holes provided at the upper and lower ends.

[0009] As a further embodiment of this utility model, the positioning assembly includes a positioning screw, a washer, and a mating nut. There are two washers, which are respectively placed on the center of the outer surface of the upper and lower welding positioning through holes. The positioning screw passes through the upper washer and the welding positioning through hole, passes through the handrail insertion end, and exits through the lower washer and the welding positioning through hole. The mating nut is threaded to the top of the positioning screw and pressed against the bottom surface of the lower washer.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In practical application, this utility model involves installing the fixed end mounting plate on the supports at both ends of the staircase. One end of the handrail is then inserted into the handrail end connector. Another handrail connector is then inserted into the other end of the handrail. The inclination of the entire handrail is adjusted according to the staircase's slope. Once the inclination angles are aligned, the positioning screw inside the positioning assembly is inserted through the upper washer and the welding positioning hole. It then passes through the handrail insertion end and exits through the lower washer and the welding positioning hole. Finally, the mating nut is threaded onto the top of the positioning screw and pressed against the bottom surface of the lower washer, thus completing the positioning operation (applicable to handrails made of non-metallic materials). During this process, welding can also be performed between the end of the handrail end connector and the surface of the handrail end. Further welding is then performed on the handrail insertion end through the welding positioning hole.

[0012] This utility model features a handrail end insert that can rotate at any angle, allowing it to adapt to handrail installation at different tilt angles. It can serve as a universal component for handrail installation. The added positioning component also allows it to be used for non-metallic handrails. In conjunction with the welding positioning holes, it can also increase the number of welding positioning points for metallic handrails, thereby increasing the welding strength.

The fixed end mounting plate 1 has hinged side plates 2 installed on both sides of its front end. The handrail end insertion pipe 3 has a hinge shaft 4 fixedly connected to its tail end. The two ends of the hinge shaft 4 are rotatably connected between the two hinged side plates 2. The upper and lower ends of the handrail end insertion pipe 3 are provided with welding positioning through holes 5. The handrail inserted inside the handrail end insertion pipe 3 is fixed by positioning components 6 passing through the welding positioning through holes 5 at the upper and lower ends.

[0022] Through the above-described solution of this utility model, the handrail inserted into the handrail end insertion pipe 3 can also be welded to its upper and lower surfaces by passing through the edge of the welding positioning through hole 5 provided at the upper and lower ends.

The washer 8 has two parts, which are respectively placed on the center of the outer surface of the upper and lower welding positioning through holes 5. The positioning screw 7 is inserted into the upper washer 8 and the welding positioning through hole 5, passes through the handrail insertion end, and exits at the lower washer 8 and the welding positioning through hole 5. The mating nut 9 is threadedly connected to the top of the positioning screw 7 and pressed against the bottom surface of the lower washer 8.

[0024] According to the above-described solution of this utility model, the handrail connector is made entirely of stainless steel and its surface is coated with protective paint.

[0025] In practical applications, the fixed end mounting plate 1 is installed on the supports at both ends of the staircase. Then, one end of the handrail is inserted into the inside of the handrail end insertion pipe 3. Next, another handrail connector is inserted into the other end of the handrail. Then, according to the inclination of the staircase, the inclination of the entire handrail is adjusted. After the inclination angle is adjusted to be consistent, the positioning screw 7 inside the positioning component 6 is inserted into the upper washer 8 and the welding positioning through hole 5. Then, it passes through the handrail insertion end and exits through the lower washer 8 and the welding positioning through hole 5. Finally, the mating nut 9 is threaded onto the top of the positioning screw 7 and pressed against the bottom surface of the lower washer 8, thus completing the positioning operation (applicable to handrails made of non-metallic materials). During this process, welding operations can also be performed on the end of the handrail end insertion pipe 3 and the surface of the handrail end. Then, further welding operations are performed on the handrail insertion end through the welding positioning through hole 5.
