Description

Technical Field

[0001] This utility model relates to the technical field of handrail support components, and in particular to an adjustable handrail support component. Background Technology

[0002] In public facilities, transportation vehicles, medical equipment, or furniture, handrails are key components that provide support and safety. Their installation needs to be adapted to diverse scenario requirements. In existing technologies, handrail support components usually adopt a fixed structure, that is, the connection position between the main body of the support component and the handrail is predetermined by welding, bolt fixing, or integral molding.

[0003] When handrail support components are in use, existing handrail support components typically adopt a fixed structure, which cannot be adjusted in terms of spacing or size after installation. This results in the same model of product only being able to fit handrails of specific specifications, leading to poor versatility. Such designs have significant limitations when dealing with handrails of different widths, heights, or with limited installation space. For example, the handrails of seats in public places need to be compatible with various models of seat frames, while the installation space of handrails in transportation vehicles (such as wheelchairs and buses) is often limited by the structure. Traditional fixed support components cannot meet the versatility requirements, resulting in the need for additional customization or structural adjustments during installation, which increases manufacturing costs and usage complexity.

[0004] Therefore, to address the aforementioned problem of inconvenience in matching handrails of different installation sizes, an adjustable handrail support can be designed. When using the handrail support, the user first needs to pull the positioning mechanism outward. At this time, the connecting cylinder is in an adjustable unlocked state. Then, the user pushes the connecting cylinder inward. When the connecting cylinder moves to the target position and the distance between it and the fixed cylinder matches the current handrail specification, the user releases the positioning mechanism to lock the connecting cylinder. At this time, the distance between the connecting cylinder and the fixed cylinder is fixed, and the handrail support is adjusted. In summary, this technical solution, through innovative mechanical structure design, achieves flexible adjustment and reliable fixation of the handrail support while ensuring support strength. Specifically, by adjusting the distance between the connecting cylinder and the fixed cylinder laterally, it can match handrails of different widths or installation sizes, solving the problem of the single specification of traditional fixed support components and improving the versatility and practicality of the product. Utility Model Content

[0005] To overcome the problem that existing handrail support components typically use a fixed structure, resulting in the same model of product only being compatible with handrails of specific specifications, thus having poor versatility and being inconvenient to match handrails of different installation sizes.

[0006] The technical solution of this utility model is as follows: an adjustable handrail fulcrum support, including a support body, the outer shape of the support body is rectangular, two sets of fixed cylinders are fixedly arranged in the inner cavity on the back, and a connecting cylinder is also included. Two sets of horizontally adjustable connecting cylinders are arranged in the inner cavity on the back of the support body. The connecting cylinders and the fixed cylinders are the same size. The two sets of fixed cylinders and the two sets of connecting cylinders are fixedly connected by vertical plates.

[0007] Preferably, when the handrail fulcrum support is in use, the user first needs to pull the positioning mechanism outward. At this time, the connecting cylinder is in an adjustable unlocked state. Then, the user pushes the connecting cylinder inward. When the connecting cylinder moves to the target position and the distance between it and the fixed cylinder matches the current handrail specification, the user releases the positioning mechanism to lock the connecting cylinder. At this time, the distance between the connecting cylinder and the fixed cylinder is fixed, and the handrail fulcrum support is adjusted. In summary, this technical solution, through the innovative design of the mechanical structure, achieves flexible adjustment and reliable fixation of the handrail fulcrum support while ensuring support strength. Specifically, by adjusting the distance between the connecting cylinder and the fixed cylinder laterally, it can match handrails of different widths or installation sizes, solving the problem of the single specification of traditional fixed support components and improving the versatility and practicality of the product.

[0008] Preferably, a connecting plate is fixedly installed on the outer circumferential surface of both the fixed cylinder and the connecting cylinder. A transverse sliding groove is opened through the connecting plate on the outer wall of the fixed cylinder, and a sliding rod is fixedly installed inside the sliding groove. A C-shaped frame is fixedly installed at the end of the connecting plate on the outer wall of the connecting cylinder, and the middle crossbar of the C-shaped frame passes through the side wall of the sliding rod and is slidably connected to the sliding rod.

[0009] Preferably, the inner wall of the inner cavity on the back of the support body is provided with two sets of transverse guide grooves, a guide rod is fixedly installed inside the guide groove, a guide block that can slide laterally is sleeved on the side wall of the guide rod, and the outer end of the guide block is fixedly connected to the bottom surface of the connecting cylinder protrusion plate.

[0010] Preferably, a support plate is fixedly installed on the inner wall of the back cavity of the support body, and a fixing plate is fixedly installed between the two sets of connecting cylinders. A through groove is opened inside the fixing plate, and the support plate is installed inside the through groove.

[0011] Preferably, a fixing block and a support block are fixedly installed on the side wall of the fixing plate. The fixing block and the support block are the same size, and both have through holes and are on the same horizontal axis.

[0012] Preferably, a positioning rod is slidably installed inside the fixed plate, and multiple sets of horizontally arranged positioning holes are opened inside the support plate. One end of the positioning rod is engaged with the through hole and the positioning hole inside the support block.

[0013] Preferably, a positioning ring is fixedly provided on the side wall of the other end of the positioning rod, and a positioning spring is fixedly provided on the inner wall of the positioning ring. One end of the positioning spring is fixedly connected to the side wall of the fixing block, and the positioning spring is sleeved on the outside of the positioning rod.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using the handrail fulcrum support component, the user first needs to pull the positioning mechanism outward. At this time, the connecting cylinder is in an adjustable unlocked state. Then, the user pushes the connecting cylinder inward. When the connecting cylinder moves to the target position and the distance between it and the fixed cylinder matches the current handrail specification, the user releases the positioning mechanism to lock the connecting cylinder. At this time, the distance between the connecting cylinder and the fixed cylinder is fixed, and the handrail fulcrum support component is adjusted. In summary, this technical solution, through innovative mechanical structure design, achieves flexible adjustment and reliable fixation of the handrail fulcrum support component while ensuring support strength. Specifically, by adjusting the distance between the connecting cylinder and the fixed cylinder laterally, it can match handrails of different widths or installation sizes, solving the problem of the single specification of traditional fixed support components and improving the versatility and practicality of the product.

[0016] 2. Simply pull the positioning rod to unlock, and push the connecting cylinder to release for automatic locking. The operation is simple, requiring no complicated tools or professional personnel, lowering the barrier to entry. The sliding cooperation between the C-shaped frame and the slide rod, and the guiding constraint between the guide block and the guide rod, together ensure the smooth lateral movement of the connecting cylinder, preventing skewing or shaking during adjustment and ensuring support stability. The positioning rod also engages with the positioning hole of the support plate and the through hole of the support block, forming a double locking mechanism. Combined with the elastic restoring force of the positioning spring, it effectively prevents accidental loosening caused by vibration or external force, improving safety. All components are integrated into the inner cavity of the support body, resulting in a compact structure that does not occupy additional external space, making it suitable for scenarios with limited installation space.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] This application can effectively solve the problem of adapting and installing handrail support components with handrails of different specifications. Based on the connection method of the handrail support components, it improves the adaptability and installation effect of the handrail support components.

[0025] However, in this embodiment, the connection method of the handrail support point is improved based on the handrail support point support member. Please refer to [link / reference needed]. Figure 1 and Figure 2 This utility model provides an embodiment: an adjustable handrail fulcrum support, including a support body 1, the support body 1 having a rectangular outer shape, and two sets of fixing cylinders 2 fixedly disposed in the inner cavity on its back side, and also including a connecting cylinder 3, the inner cavity on the back side of the support body 1 being provided with two sets of horizontally adjustable connecting cylinders 3, the connecting cylinders 3 having the same size as the fixing cylinders 2, and the two sets of fixing cylinders 2 and the two sets of connecting cylinders 3 being fixedly connected by vertical plates.

[0026] Please see Figure 3 and Figure 4Both the fixed cylinder 2 and the connecting cylinder 3 have connecting plates fixedly installed on their outer circumferential surfaces. A transverse sliding groove 4 is formed through the connecting plate on the outer wall of the fixed cylinder 2, and a sliding rod 5 is fixedly installed inside the sliding groove 4. A U-shaped frame 6 is fixedly installed at the end of the connecting plate on the outer wall of the connecting cylinder 3. The middle horizontal bar of the U-shaped frame 6 passes through the side wall of the sliding rod 5 and is slidably connected to the sliding rod 5. The middle horizontal bar of the U-shaped frame 6 slides laterally along the side wall of the sliding rod 5, ensuring that the moving direction of the connecting cylinder 3 is always consistent with the transverse axis of the support body 1, avoiding deviation. Two sets of transverse guide grooves 7 are formed on the inner wall of the back cavity of the support body 1. The guide grooves 7 are fixed inside... A guide rod 8 is provided, and a guide block 9 that can slide laterally is sleeved on the side wall of the guide rod 8. The outer end of the guide block 9 is fixedly connected to the bottom surface of the convex plate of the connecting cylinder 3. The cooperation between the guide rod 8 and the guide block 9 further constrains the movement trajectory of the connecting cylinder 3, so that it can only move smoothly along the preset lateral path and prevent tilting or jamming. A support plate 17 is fixedly provided on the inner wall of the back cavity of the support body 1. A fixing plate 16 is fixedly provided between the two sets of connecting cylinders 3. A through groove is opened inside the fixing plate 16. The support plate 17 is set inside the through groove. The fixing plate 16 uses the through groove to achieve smooth sliding along the support plate 17.

[0027] Please see Figure 2 and Figure 5 A fixing block 10 and a support block 11 are fixedly installed on the side wall of the fixing plate 16. The fixing block 10 and the support block 11 are the same size. Both have through holes that are located on the same horizontal axis. The positioning rod 12 engages with the positioning hole 13 of the support plate 17 and the through hole of the support block 11, forming a double locking mechanism. The positioning rod 12 is slidably installed inside the fixing plate 16. The support plate 17 has multiple sets of horizontally arranged positioning holes 13 that are opened through it. One end of the positioning rod 12 engages with the through hole inside the support block 11 and the positioning hole 13. Simultaneously, it engages with the positioning hole 13 of the support plate 17 and the through hole of the support block 11, forming a double locking mechanism. A positioning ring 14 is fixedly installed on the side wall of the other end of the positioning rod 12. A positioning spring 15 is fixedly installed on the inner wall of the positioning ring 14. One end of the positioning spring 15 is fixedly connected to the side wall of the fixing block 10, and the positioning spring 15 is sleeved on the outside of the positioning rod 12. The positioning spring 15 generates a retraction force due to the elastic deformation recovery, which pulls the positioning ring 14 and the positioning rod 12 to move towards the support plate 17. One end of the positioning rod 12 is reinserted into the positioning hole 13 at the corresponding position of the support plate 17.

[0028] When the handrail fulcrum support is in use, firstly, the user needs to pull the positioning rod 12 outward. After the positioning rod 12 is subjected to external force, one end of it comes out of the positioning hole 13 corresponding to the support plate 17. At the same time, the positioning ring 14 on the side wall of the positioning rod 12 moves accordingly. At this time, the positioning spring 15 is in a stretched state. Since the positioning rod 12 is properly matched with the through hole inside the support block 11, when the positioning rod 12 is disengaged from the positioning hole 13, the locking relationship between the support block 11 and the fixing plate 16 is released, and the connecting cylinder 3 is in an adjustable unlocked state.

[0029] Subsequently, the user pushes the connecting cylinder 3 inward. During the lateral movement, the connecting cylinder 3 slides relative to the sliding rod 5 inside the connecting plate of the outer wall of the fixed cylinder 2 through the C-shaped frame 6 at the end of its outer wall connecting plate. The middle crossbar of the C-shaped frame 6 slides laterally along the side wall of the sliding rod 5, ensuring that the moving direction of the connecting cylinder 3 is always consistent with the lateral axis of the support body 1, avoiding deviation. At the same time, the guide block 9 fixed on the bottom surface of the convex plate of the connecting cylinder 3 slides laterally along the guide rod 8 on the inner wall of the support body 1. The cooperation between the guide rod 8 and the guide block 9 further constrains the moving trajectory of the connecting cylinder 3, so that it can only move smoothly along the preset lateral path, preventing tilting or jamming.

[0030] When the connecting cylinder 3 moves to the target position and the distance between it and the fixed cylinder 2 matches the current handrail specifications, the user releases the positioning rod 12. The previously stretched positioning spring 15 recovers its elastic deformation and generates a retraction force, pulling the positioning ring 14 and the positioning rod 12 towards the support plate 17. One end of the positioning rod 12 is reinserted into the positioning hole 13 at the corresponding position of the support plate 17, and at the same time passes through the through hole inside the support block 11, realizing the secondary locking between the connecting cylinder 3 and the support plate 17. Through the double engagement of the positioning rod 12 with the positioning hole 13 and the through hole of the support block 11, the distance between the connecting cylinder 3 and the fixed cylinder 2 is fixed, and the handrail fulcrum support is adjusted.

[0031] This technical solution achieves the following core advantages through modular design and mechanical linkage: it can be unlocked by simply pulling the positioning rod 12 and automatically locked by pushing the connecting cylinder 3 and releasing it. The operation steps are simple and do not require complicated tools or professional personnel, thus lowering the threshold for use. The sliding cooperation between the C-shaped frame 6 and the slide rod 5, and the guiding constraint between the guide block 9 and the guide rod 8, together ensure the stability of the lateral movement of the connecting cylinder 3, avoid skewing or shaking during adjustment, and ensure the stability of the support. The positioning rod 12 also engages with the positioning hole 13 of the support plate 17 and the through hole of the support block 11 to form a double locking mechanism. Combined with the elastic restoring force of the positioning spring 15, it effectively prevents accidental loosening caused by vibration or external force, improving the safety of use. All components are integrated into the inner cavity of the main body 1 of the support, with a compact structure that does not occupy additional external space, making it suitable for scenarios with limited installation space.

[0032] In summary, this technical solution, through innovative mechanical structure design, achieves flexible adjustment and reliable fixation of the handrail fulcrum support while ensuring support strength. Specifically, by adjusting the distance between the connecting cylinder 3 and the fixed cylinder 2 laterally, it can match handrails of different widths or installation sizes, solving the problem of the single specification of traditional fixed support components and improving the versatility and practicality of the product.

[0033] Through the above steps, when the handrail support is in use, the user first needs to pull the positioning mechanism outward. At this time, the connecting cylinder 3 is in an adjustable unlocked state. Then, the user pushes the connecting cylinder 3 inward. When the connecting cylinder 3 moves to the target position and the distance between it and the fixed cylinder 2 matches the current handrail specification, the user releases the positioning mechanism to lock the connecting cylinder 3. At this time, the distance between the connecting cylinder 3 and the fixed cylinder 2 is fixed, and the handrail support is adjusted. In summary, this technical solution, through the innovative design of the mechanical structure, achieves flexible adjustment and reliable fixation of the handrail support while ensuring support strength. Specifically, by adjusting the distance between the connecting cylinder 3 and the fixed cylinder 2 laterally, handrails of different widths or installation sizes can be matched, solving the problem of the single specification of traditional fixed support components and improving the versatility and practicality of the product.
