Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a building handrail corner connector. Background Art

[0002] A handrail is a component located at the upper end of a railing or balustrade and on the side wall of a stairway for people to hold on to. Its form and material selection must not only meet people's requirements for climbing and a comfortable feel, but also meet the requirements of being a decorative component. It is commonly made of hardwood, plastic, reinforced concrete, terrazzo, marble, and metal profiles. There is no uniform standard for its form, and the specific method is determined by the detailed construction drawings. Indoor stair handrails take into account the comfort of people when holding on, and generally use wooden handrails. The size is related to the human body size. The primary function of a railing handrail is to prevent people from falling from heights or stairs, especially in high-altitude areas such as high floors, roofs, balconies, and bridges. In complex or crowded public buildings, handrails can guide the direction of pedestrian flow, reduce congestion and the occurrence of accidents. On stairs or ramps, handrails provide pedestrians with assistance in going up or down, especially for people carrying heavy objects or with weak physical strength. This function is particularly important.

[0003] In modern life, escalators generally use wood as escalator handrails. Plastic handrails also feel good, but have poor durability and are no longer widely used. Metal handrails have good durability and wear resistance and can be processed into various shapes. They are mostly used in public buildings. The disadvantage is that they feel poor when used in winter and people are generally reluctant to touch them. Therefore, wooden handrails are more commonly used. Since wood is a natural material, the unevenness of its texture and hardness may make it difficult to achieve a perfect joint during processing. Wood splinters or cracks at corners are common problems, especially in hard miscellaneous woods. These sharp objects can easily injure the user's hands. In addition, wooden handrails may be deformed due to changes in ambient temperature and humidity, further exacerbating the unevenness problem at the joints. The size standardization of wood materials is low, and products from different batches or suppliers may have slight size differences, which brings limitations to the selection and replacement of handrail connection components.

[0022] 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 only 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.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] See Figure 1-Figure 4The invention discloses a corner connector for a building handrail, wherein the first shell 1 is a structural frame, which wraps and protects the internal mechanical components from the influence of the external environment. Because the bottom of the long sliding block 201 is in close contact with the outer wall of the first extension clamping plate 202, when external pressure acts on the protrusion above the long sliding block 201, the extension mechanism of the first extension clamping plate 202 is triggered, so that the outer part of the first extension clamping plate 202 extends outward to expand the clamping range. This process significantly increases the width that the first extension clamping plate 202 can clamp, so that the component can be integrated. The body is better fixed on the handrail and can be better connected to the corner of the handrail. In order to ensure that the first extension splint 202 can be reset after being extended, a spring 203 is installed in the gap below the first extension splint 202 inside the first shell 1. This spring 203 not only provides the necessary resilience for the first extension splint 202, but also allows the connector to have a certain degree of adjustability under different stair handrail widths, thereby improving the plasticity of the entire component, enabling it to better adapt to the needs of different buildings, but also ensuring that the connector can maintain good performance even after repeated use.

[0025] At the corners of the connector, in order to cope with the different pressures and forces that the building handrail is subjected to at the corners, the cone block 204 arranged inside the second shell 5 has a polygonal cone shape. This design is to optimize the mechanical properties at the corners and ensure the stability and safety of the handrail at the corners. When external forces act, the cone block 204 can guide these forces to be more effectively transmitted to the second extended splint 205. Due to the structural advantages of the cone block 204, the second extended splint 205 can be smoothly extended from the second shell 5 when subjected to force. This process not only enhances the expansion ability of the handrail at the corners, but also ensures the flexibility and accuracy of adjustment during installation. In actual building applications, this design means that installers can quickly and accurately adjust the angle and length of the handrail according to the specific building structure and user needs, making the handrail system not only more visually harmonious, but also more functionally user-friendly. The use of the cone block 204 and the second extended splint 205 at the corners improves the overall performance of the handrail system, enabling it to exhibit high stability and reliability when subjected to forces in different directions.

[0026] A cushion 4 is bonded to the first extension splint 202. The cushion 4 is made of materials such as natural rubber, nitrile rubber, and EPDM. The cushion 4 has high elasticity and tear strength and is suitable for applications requiring high wear resistance and elasticity. Nitrile rubber is widely used in environments requiring oil resistance due to its excellent oil resistance, while EPDM has excellent heat resistance, aging resistance, and ozone resistance. These rubber materials can not only provide sufficient cushioning effects but also ensure durability in various environments. At the same time, when the first extension splint 202 is extended, the cushion 4 is bonded to the first extension splint. 202, so the protective property of the cushion 4 is always present on the first extended splint 202. The cushion 4 can absorb and disperse the force generated by the impact. When the human body comes into contact with the sharp angle at the corner of the escalator, the cushion 4 plays a buffering role, significantly reducing the possibility of injury. By covering the sharp edges, the probability of any part of the body coming into direct contact with hard objects is reduced, providing an additional layer of safety protection for the user. Children and the elderly are more susceptible to injuries from bumps due to their physiological characteristics. The use of the cushion 4 is especially important for people of these two age groups, and can provide them with more safety protection in daily life.

[0027] See Figure 3 、 Figure 5 As shown, after the clamping assembly 2 is fixed to the escalator handrail, the fixing block 303 installed on the fixing assembly 3 at the bottom of the first extension splint 202 is rotatably connected to the telescopic rod 302 through the rotating shaft 301. Since the sliding rod 304 is installed on the telescopic rod 302, the sliding rod 304 is extended to the corresponding length of the extension of the first extension splint 202. After that, the telescopic rod 302 is rotated to insert the screw 305 into the corresponding slot at the bottom of the other end of the first extension splint 202 and rotate it to connect. This ensures that the escalator connector will not fall off due to accidental touch during the fixing process.

[0028] Working principle: When external pressure acts on the protrusion above the long sliding block 201, the extension mechanism of the first extension splint 202 will be triggered, so that the outer part of the first extension splint 202 extends outward to expand the clamping range. This process significantly increases the width that the first extension splint 202 can clamp, so that the entire component can be better fixed on the handrail and can be better connected to the handrail corner. In order to ensure that the first extension splint 202 can be reset after being extended, a spring 203 is installed in the gap below the first extension splint 202 inside the first shell 1. This spring 203 not only provides the necessary rebound force for the first extension splint 202, but also allows the connector to have a certain degree of adjustability under different stair handrail widths. At the corner of the connector, in order to cope with the different pressures and forces that the building handrail is subjected to at the corner, the cone block 204 arranged inside the second shell 5 has a polygonal cone shape. This design In order to optimize the mechanical properties at the corners and ensure the stability and safety of the handrail at the corners, when external forces act, the cone block 204 can guide these forces to be more effectively transmitted to the second extension splint 205. Due to the structural advantages of the cone block 204, the second extension splint 205 can be smoothly extended from the second shell 5 when subjected to force. After the clamping assembly 2 is fixed to the escalator handrail, the fixed block 303 installed at the bottom of the first extension splint 202 is rotated and connected to the telescopic rod 302 through the rotating shaft 301. Because the sliding rod 304 is installed on the telescopic rod 302, after extending the sliding rod 304 to the corresponding length of the expanded width of the first extension splint 202, the telescopic rod 302 is rotated to insert the screw 305 into the corresponding slot at the bottom of the other end of the first extension splint 202 and rotate it to connect. This ensures that the escalator connector will not fall off due to accidental touch during fixation.
