Description

Technical Field

[0001] This utility model relates to the field of engineering decoration technology, and in particular to a single-line handrail. Background Technology

[0002] A handrail is an auxiliary support device installed in specific areas of a building, primarily in bathrooms and toilets. Its main function is to provide users with a point of support for their hands, helping to maintain balance and reducing the risk of accidental falls, making it especially suitable for the elderly, children, and people with mobility impairments.

[0003] Structurally, handrails consist of a load-bearing main body, mounting components, and auxiliary structures. The load-bearing main body is mostly rod-shaped or plate-shaped and is fixed to the wall or glass support surface by the mounting components. The auxiliary structures are used to enhance the convenience and safety of use, making them facilities that improve the safety and humanization of the venue.

[0004] Existing handrails are fixed to the supporting surface through mounting components, relying on the rigidity of the main structure to transfer force and support users, thus preventing falls when unsupported. However, the mounting components of existing handrails mostly use metal connectors that are in direct contact with the supporting surface, exposing these metal connectors to the environment during use. When used in the humid environment of a bathroom, moisture can easily penetrate the handrail through the gaps between the connectors and the supporting surface. Furthermore, prolonged contact with moisture can cause oxidation of the metal connectors, leading to gradual corrosion and affecting the structural stability and lifespan of the handrail, thus reducing safety during use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a straight handrail, which aims to improve the problem that when the existing technology is applied to the humid environment of the bathroom, moisture can easily penetrate into the handrail through the gap between the connector and the support surface, causing the connector to gradually corrode and reducing the safety of use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a single-bar handrail, comprising two main rods, with a force-bearing frame fixedly connected to the outer side of each of the two main rods, and an installation mechanism provided at the upper and lower ends of the front side of each of the two force-bearing frames, the installation mechanism being used to install the handrail on the inner side of the glass panel of the bathroom, and a length adjustment mechanism being provided between the two main rods, the length adjustment mechanism being used to adjust the overall length of the handrail;

[0007] The installation mechanism includes multiple mounting bolts. Mounting grooves are provided at the upper and lower front ends of both load-bearing frames. Threaded grooves are provided at the inner ends of the mounting grooves, which are threaded to the ends of the corresponding mounting bolts. Stainless steel pressure blocks are slidably connected to the outer sides of the mounting bolts. Circular rubber sheets are fixedly connected to the upper and lower front ends of both load-bearing frames and the rear sides of the stainless steel pressure blocks. Rubber sleeves are fitted inside the mounting grooves, and the mounting bolts pass through the interior of the rubber sleeves. The rubber sleeves prevent the mounting bolts from colliding with the glass plate.

[0008] As a further description of the above technical solution:

[0009] The length adjustment mechanism includes two fixed sleeves, which are respectively fixedly connected to the inner sides of two main rods. A solid column is fixedly connected inside each of the two fixed sleeves. An adjusting rod is slidably connected between each of the two fixed sleeves and the two solid columns. Multiple positioning holes are equidistantly opened at the bottom of the adjusting rod. A fastening screw passes through the bottom of each of the two fixed sleeves. The ends of the two fastening screws pass through the two positioning holes and are threaded to the bottom of the two solid columns.

[0010] As a further description of the above technical solution:

[0011] The mounting mechanism also includes multiple conical pressure rings, which are respectively fixedly connected to the outer front side of multiple mounting bolts, and the shape of the multiple conical pressure rings is conical.

[0020] As a further description of the above technical solution:

[0021] The adjusting rod has a hollow interior and an anti-slip exterior.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the installation bolt passes through the rubber sleeve and is threadedly connected to the installation groove. When rotated, the stainless steel pressure block is pushed close to the force-bearing frame.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model is provided: a single-bar handrail, including two main rods 1, with a force-bearing frame 2 fixedly connected to the outer side of each of the two main rods 1, and an installation mechanism 3 provided at the upper and lower ends of the front side of each of the two force-bearing frames 2. The installation mechanism 3 is used to install the handrail on the inner side of the glass panel of the bathroom. A length adjustment mechanism 4 is provided between the two main rods 1, and the length adjustment mechanism 4 is used to adjust the overall length of the handrail.

[0034] The mounting mechanism 3 includes multiple mounting bolts 31. The upper and lower ends of the front sides of the two load-bearing frames 2 are provided with mounting grooves 32. The inner ends of the multiple mounting grooves 32 are provided with threaded grooves, which are threaded to the ends of the corresponding mounting bolts 31. The outer sides of the multiple mounting bolts 31 are slidably connected with stainless steel pressure blocks 33. The upper and lower ends of the front sides of the two load-bearing frames 2 and the rear sides of the multiple stainless steel pressure blocks 33 are fixedly connected with circular rubber sheets 34. The interior of the multiple mounting grooves 32 is fitted with rubber sleeves 35. The multiple mounting bolts 31 pass through the interior of the rubber sleeves 35. The multiple rubber sleeves 35 are used to prevent the mounting bolts 31 from colliding with the glass plate. The mounting mechanism 3 also includes multiple conical pressure rings 36. The multiple conical pressure rings 36 are fixedly connected to the outer front side of the multiple mounting bolts 31. The multiple conical pressure rings 36 are all designed with a conical shape.

[0035] Specifically, in the installation mechanism 3, the mounting grooves 32 at the upper and lower ends of the front side of the force-bearing frame 2 provide space for installation, and the inner end threaded groove is threadedly connected to the end of the mounting bolt 31; the stainless steel pressure block 33 is slidably connected to the outside of the mounting bolt 31, and it and the circular rubber sheet 34 on the front side of the force-bearing frame 2 respectively adhere to both sides of the glass plate.

[0036] During installation, the mounting bolt 31 passes through the rubber sleeve 35, and the rubber sleeve 35 is fitted inside the mounting groove 32 to prevent the mounting bolt 31 from directly contacting and colliding with the glass plate; rotating the mounting bolt 31 causes it to move axially along the threaded groove, pushing the stainless steel pressure block 33 closer to the force-bearing frame 2.

[0037] During the movement of the stainless steel pressure block 33, the circular rubber sheet 34 is squeezed and deformed, filling the gap between the glass plate and the component; the conical pressure ring 36 rotates with the mounting bolt 31, and its conical design concentrates the pressure in the center of the stainless steel pressure block 33, ensuring uniform force distribution.

[0038] When the mounting bolt 31 is tightened to the preset position, the stainless steel pressure block 33 and the force-bearing frame 2 form a clamping force on the glass plate through the circular rubber sheet 34. The friction of the rubber sheet prevents the components from sliding, thus fixing the handrail to the glass plate. The rubber sleeve 35 isolates the mounting bolt 31 from the glass plate during installation to avoid scratches caused by metal contact. The conical pressure ring 36 enhances the contact stability between the mounting bolt 31 and the stainless steel pressure block 33 and prevents slippage.

[0039] The two main rods 1 are connected by a length adjustment mechanism 4, which can adjust the overall length according to the spacing of the bathroom glass panels; the force-bearing frame 2 transmits the force of the main rods 1, and the multi-point fixing design of the installation mechanism 3 distributes the load and improves the overall installation strength;

[0040] The elastic deformation of the circular rubber sheet 34 can adapt to the slight unevenness of the glass plate surface, ensuring that the clamping force of each installation point is consistent, while preventing water from entering the handrail and causing the mounting bolt 31 to rust after long-term use. The engagement of the mounting bolt 31 with the threaded groove provides adjustable clamping force to accommodate glass plates of different thicknesses.

[0041] The length adjustment mechanism 4 works in conjunction with the installation mechanism 3 to enable the handrail to adapt to different installation scenarios while ensuring the structural stability after installation and ensuring that the handrail does not loosen when subjected to external forces during use.

[0042] The symmetrical design of the mounting mechanism 3 balances the forces on the two main rods 1, preventing excessive force on one side from causing installation failure; the rigid structure of the stainless steel pressure block 33 ensures effective transmission of clamping force, while the flexible properties of the circular rubber sheet 34 protect the glass plate from damage, achieving stable installation of the handrail in the bathroom environment and preventing moisture from entering the handrail and causing the mounting bolts 31 to rust.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The length adjustment mechanism 4 includes two fixed sleeves 41, which are fixedly connected to the inner sides of the two main rods 1 respectively. A solid column 42 is fixedly connected inside each of the two fixed sleeves 41. An adjustment rod 43 is slidably connected between the two fixed sleeves 41 and the two solid columns 42. Multiple positioning holes 44 are equidistantly opened at the bottom of the adjustment rod 43. Fastening screws 45 pass through the bottom of each of the two fixed sleeves 41. The ends of the two fastening screws 45 pass through the inside of the two positioning holes 44 and are threaded to the bottom of the two solid columns 42 respectively. The length adjustment mechanism 4 also includes multiple anti-slip grooves 46, which are equidistantly opened on the outer sides of the two fixed sleeves 41 respectively.

[0044] Specifically, in the length adjustment mechanism 4, two fixed sleeves 41 are fixed to the inner side of the two main rods 1 respectively, and solid columns 42 are fixed inside each. The adjusting rod 43 is slidably connected between the fixed sleeves 41 and the solid columns 42. The positioning hole 44 at the bottom of the adjusting rod 43 cooperates with the fastening screw 45 at the bottom of the fixed sleeve 41. The end of the fastening screw 45 passes through the positioning hole 44 and is threaded to the bottom of the solid column 42.

[0045] When adjusting the length of the handrail, loosen the fastening screw 45 to disengage it from the positioning hole 44 and the solid column 42, thereby releasing the lock on the adjusting rod 43; external force is applied to the two main rods 1, causing the fixing sleeve 41 to slide along the axial direction of the adjusting rod 43, thus changing the distance between the two main rods 1.

[0046] During the sliding process of the fixed sleeve 41, the solid column 42 and the adjusting rod 43 remain in contact to ensure a stable sliding trajectory. When the target length is reached, the fastening screw 45 at the bottom of the fixed sleeve 41 is aligned with the corresponding positioning hole 44 of the adjusting rod 43. The fastening screw 45 is tightened so that it passes through the positioning hole 44 and is threadedly connected to the solid column 42 to achieve length locking.

[0047] The anti-slip groove 46 on the outside of the fixed sleeve 41 increases the friction for hand gripping, making it easier to apply force during adjustment; the solid column 42 provides a threaded connection base for the fastening screw 45, enhancing the locking strength; the sliding fit between the adjusting rod 43 and the fixed sleeve 41 allows the length adjustment range to be determined by the length of the adjusting rod 43 and the number of positioning holes 44; the equidistant distribution of multiple positioning holes 44 provides multiple adjustment options to adapt to different bathroom glass panel spacings;

[0048] The threaded connection between the fastening screw 45 and the solid column 42 generates axial pressure, which clamps the adjusting rod 43 between the fixing sleeve 41 and the solid column 42, preventing slippage due to vibration during use; the anti-slip groove 46 assists in applying force during adjustment, preventing hand slippage and affecting operating efficiency.

[0049] The length adjustment mechanism 4 works in conjunction with the installation mechanism 3. The sliding adjustment of the adjustment rod 43 provides the installation mechanism 3 with an installation base that can accommodate different spacings. The clamping force of the installation mechanism 3 fixes the adjusted length. The fixing sleeve 41 transmits the force on the main rod 1 to the adjustment rod 43, dispersing the torque generated during use.

[0050] The solid column 42 enhances the structural rigidity of the fixed sleeve 41 and prevents the fixed sleeve 41 from deforming when the adjusting rod 43 slides; the fit between the positioning hole 44 and the fastening screw 45 ensures the length accuracy after each adjustment and prevents loosening or deviation.

[0051] The anti-slip groove 46 is designed to facilitate adjustment and enhance the friction on the side of the armrest during daily use, thereby improving grip safety; the rigid material of the adjustment rod 43 ensures that it will not bend when the main rod 1 is under load, thus ensuring the overall structural stability.

[0052] The multi-position adjustment function of the length adjustment mechanism 4, combined with the adaptability of the installation mechanism 3, enables the handrail to adapt to various bathroom layouts; through mechanical locking and sliding cooperation, precise control and stable maintenance of the length are achieved, providing flexible support for the installation and use of the handrail.

[0053] Reference Figure 1 , Figure 3 and Figure 4 Both load-bearing frames 2 adopt an eight-shaped design and a symmetrical shape with a smooth exterior. Multiple stainless steel pressure blocks 33 have cover caps 5 that are snapped onto their front sides. The internal dimensions of the cover caps 5 match the external diameter of the stainless steel pressure blocks 33. The bottom of both main rods 1 are fixedly connected to hooks 6, and the hooks of both hooks 6 are designed to be inward. The adjusting rod 43 has a hollow interior and an anti-slip exterior.

[0054] Specifically, the support frame 2 adopts a figure-eight symmetrical design, which can distribute the force transmitted by the main rod 1 and enhance the stability of contact with the glass plate; the smooth external design avoids bumps and damage during use; the cover cap 5 that snaps into the front of the stainless steel pressure block 33 has an internal size that matches the stainless steel pressure block 33, which can cover the mounting bolt 31, prevent water stains from entering and affecting the structure, and improve the aesthetics; the hook 6 fixed at the bottom of the main rod 1 has an inward-facing design at the bend, which makes it easy to hang items and prevents the hung items from slipping; the hollow design of the adjusting rod 43 reduces the overall weight, and the external anti-slip process increases the friction of hand contact and improves the grip stability during use.

[0055] Working principle: Before installation, adjust the handrail length according to the spacing between the bathroom glass panels: Loosen the fastening screw 45 of the length adjustment mechanism 4 so that it is disengaged from the positioning hole 44 and solid column 42 of the adjustment rod 43; Hold the anti-slip groove 46 on the outside of the fixing sleeve 41 and apply external force to make the two main rods 1 drive the fixing sleeve 41 to slide along the adjustment rod 43 until the spacing between the two main rods 1 matches the spacing between the glass panels; Align the fastening screw 45 with the corresponding positioning hole 44, tighten the screw so that it passes through the positioning hole 44 and is threaded to the solid column 42 to complete the length locking;

[0056] After length adjustment, proceed with installation and fixation: Place the support frame 2 against the inner side of the glass plate, ensuring the stainless steel pressure block 33 of the installation mechanism 3 and the support frame 2 are located on opposite sides of the glass plate; the installation bolt 31 passes through the rubber sleeve 35, with its end connected to the threaded groove inside the installation slot 32; rotate the installation bolt 31 to push the stainless steel pressure block 33 closer to the support frame 2, causing the circular rubber sheet 34 to deform under pressure; the conical pressure ring 36 concentrates the pressure at the center of the stainless steel pressure block 33, ensuring uniform force; when tightened to the preset position, the circular rubber sheet 34 tightly adheres to the glass plate, forming a clamping force, completing the installation;

[0057] After installation, the cover cap 5 is snapped onto the front of the stainless steel pressure block 33 to cover the mounting bolt 31; during use, the force on the main rod 1 is distributed to the glass plate through the figure-eight force frame 2, and the smooth external design avoids bumps; the hand grips the external anti-slip area of ​​the mounting mechanism 3, and the main rod 1 supports the body; the hook 6 can hang items, and the inward-curved hook prevents slipping;

[0058] If the length needs to be adjusted, repeat the above length adjustment steps: loosen the fastening screw 45, slide the fixing sleeve 41 to the new position, and lock it again; during maintenance, remove the cover cap 5 to check or replace the mounting bolt 31.

[0059] The hollow design of the mounting mechanism 3 reduces weight, and the rubber sleeve 35 isolates the metal and glass plate to prevent scratches and corrosion; the multi-positioning hole 44 design of the length adjustment mechanism 4 provides multiple position options, and the solid column 42 enhances the locking strength; the figure-eight symmetrical structure of the force-bearing frame 2 balances the force and improves stability.

[0060] The cover cap 5 prevents water stains from entering the mounting bolt 31, extending its service life; the anti-slip technology of the adjusting rod 43 enhances grip safety, and the elasticity of the circular rubber sheet 34 adapts to the unevenness of the glass plate, ensuring consistent clamping force; the inward design of the hook 6 combines practicality and safety, and the anti-slip groove 46 of the fixing sleeve 41 facilitates adjustment; all components achieve force transmission, dispersion and locking through mechanical cooperation, ensuring that the handrail does not loosen or deform when bearing external force;

[0061] The overall structure is adaptable to different bathroom layouts. With its adjustable length, stable installation, and safe use, it meets the needs for support and hanging items in the bathroom environment, while also being anti-collision, anti-rust, and easy to maintain.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
