Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a handrail. Background Technology

[0002] To prevent slippery floors from causing falls and injuries, handrails are usually installed in bathrooms or shower areas. Most handrails on the market are installed and fixed to the wall using wall-locking elbows at both ends of the handrail body. The handrail body often has a non-slip handrail surface tube to improve grip stability. The handrail surface tube, along with decorative washers, is securely installed between the wall-locking elbows at both ends of the handrail body.

[0003] However, in actual use, due to the inherent characteristics of plastic, it will shrink to a certain extent after long-term use. The originally tightly clamped plastic handrail tube will shrink due to the shrinkage of its length, resulting in a gap between the handrail tube and the washer, which will eventually cause the handrail tube to rotate, greatly reducing the stability of the handrail.

[0004] If the handrail rotates while the user is climbing, the body's center of gravity will not be effectively supported, which may cause a fall and pose a safety hazard to the user. This is especially true for special groups such as the elderly, children, or people with mobility impairments, whose consequences are more serious. Utility Model Content

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. Compared with the prior art, this utility model sets at least one anti-rotation structure between the handrail surface tube and the handrail body. The anti-rotation structure is embedded in the mounting groove, so that the handrail surface tube and the handrail body form a circumferential limiting fit, thereby restricting the relative rotation between the handrail surface tube and the handrail body. This effectively solves the problem of the handrail surface tube rotating due to the shrinkage of the plastic material, and improves the stability and safety of the handrail.

[0026] 2. Compared with the prior art, the anti-rotation structure of this utility model is detachably provided on the inner wall of the handrail surface tube or the outer wall of the handrail body. The anti-rotation structure is detachable, which facilitates the installation, maintenance and replacement of the handrail, and improves the practicality and service life of the handrail.

[0027] 3. Compared with the prior art, this utility model provides a snap-fit ​​structure on the outer wall of the handrail body or the inner wall of the handrail surface tube, so that the anti-rotation structure can be detachably installed on the handrail surface tube or the handrail body through the snap-fit ​​structure, which facilitates installation and disassembly operations and reduces the difficulty of installation and maintenance; in addition, the snap-fit ​​part can be snapped into the first opening to enhance the connection stability between the anti-rotation structure and the handrail surface tube or the handrail body, prevent the anti-rotation structure from loosening or falling off during use, and ensure the long-term stability and reliability of the handrail.

[0028] 4. Compared with the prior art, the base of this utility model is a strip structure adapted to the mounting groove and extends along the axial direction, so that the anti-rotation structure can better adapt to the shape and size of the mounting groove and improve the stability of the anti-rotation structure in the mounting groove; the anti-rotation structure can form a multi-point connection with the handrail surface tube or handrail body through multiple snap-fit ​​parts, which improves the reliability and stability of the connection.

[0029] 5. Compared with the prior art, the horizontal cross-sectional width of the end of the rib near the base of this utility model is greater than the horizontal cross-sectional width of the end away from the base, which makes the fit between the rib and the first opening tighter, improves the snap-fit ​​effect, and enhances the anti-rotation performance of the anti-rotation structure; in addition, the distribution position of the rib corresponds to the distribution position of the first opening, ensuring the precise positioning and fit of the anti-rotation structure during the installation process, avoiding installation problems caused by position deviation, and improving the accuracy and reliability of installation.

[0030] 6. Compared with the prior art, the present invention can firmly fix the washer and the bend by the tight fit between the bolt and the first nut insert, thereby enhancing the fixing effect and overall stability of the handrail.

[0031] 7. Compared with the prior art, this utility model, by setting second nut inserts inside both ends of the pipe body and screwing the bolt inserts to the second nut inserts, fixes the pipe body and the bend in place. This connection method further enhances the connection strength and stability between the pipe body and the wall-locking elbow assembly. Compared with simple welding or other connection methods, it can provide a more uniform stress distribution, making the pipe body and the bend tightly connected and less prone to loosening. This effectively prevents loosening or damage to the connection parts due to long-term use or external forces, and improves the service life and reliability of the handrail.

[0032] 8. Compared with the prior art, the wall-locking elbow assembly of this utility model includes a matching expansion head and a locking member. The locking member extends into the third opening on the washer and is fixedly connected to the expansion head. The expansion fastener can extend into the wall and form a tight frictional fixing effect with the wall through the expansion principle, thereby establishing a more solid connection between the handrail and the wall. This effectively enhances the stability of the handrail on the wall, prevents the handrail from loosening or shifting due to external forces, and provides users with a safer and more reliable climbing environment.

[0033] 9. Compared with the prior art, the present invention provides an anti-slip structure on the outside of the handrail surface tube, such as protrusions, grooves, holes, particles, etc. These anti-slip structures can effectively increase the friction between the user's hand and the handrail surface tube, thereby preventing the user from slipping when holding the handrail with wet or slippery hands, reducing the risk of falling due to slipping, greatly improving the safety of the handrail in actual use, and enhancing the user experience.

[0034] 10. Compared with the prior art, the anti-slip structure of this utility model has a variety of arrangement methods, such as arranging along the axial direction of the handrail tube, arranging along the circumferential direction, arranging along the staggered direction, or arranging densely in a local area. This diverse arrangement method can be flexibly selected according to the actual use scenario and needs, so as to effectively play the anti-slip role under different force directions and use conditions.

[0035] 11. Compared with the prior art, the present invention can avoid wear caused by the contact between the pipe body and the elbow assembly by using washers fitted on both ends of the pipe body, thereby further improving the service life of the handrail. Attached Figure Description

Detailed Implementation

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] Please see Figures 1 to 3 The present invention is a handrail, including a handrail surface tube 100 and a handrail body 200, and at least one anti-rotation structure 300 is provided between the handrail surface tube 100 and the handrail body 200.

[0044] The handrail surface tube 100 is sleeved on the outside of the handrail body 200; one of the inner wall of the handrail surface tube 100 and the outer wall of the handrail body 200 is provided with a mounting groove 110, and the other of the inner wall of the handrail surface tube 100 and the outer wall of the handrail body 200 is provided with an anti-rotation structure 300; the anti-rotation structure 300 is embedded in the mounting groove 110, so that the handrail surface tube 100 and the handrail body 200 form a circumferential limiting fit to restrict the relative rotation between the handrail surface tube 100 and the handrail body 200.

[0045] This utility model provides at least one anti-rotation structure 300 between the handrail surface tube 100 and the handrail body 200. The anti-rotation structure 300 is embedded in the mounting groove 110, which forms a circumferential limiting fit between the handrail surface tube 100 and the handrail body 200, thereby restricting the relative rotation between the handrail surface tube 100 and the handrail body 200. This effectively solves the problem of the handrail surface tube 100 rotating due to the shrinkage of the plastic material, and improves the stability and safety of the handrail.

[0046] Preferably, the anti-rotation structure 300 is detachably or integrally formed on the inner wall of the handrail surface tube 100 or the outer wall of the handrail body 200, and the mounting groove 110 extends along the axial direction of the handrail surface tube 100 or the handrail body 200.

[0047] The anti-rotation structure 300 can be detached, integrally formed, or fixed to the inner wall of the handrail surface tube 100 or the outer wall of the handrail body 200 by welding or other means. In this embodiment, the anti-rotation structure 300 is detachable, which facilitates the installation, maintenance and replacement of the handrail and improves the practicality and service life of the handrail.

[0048] In this embodiment, the handrail body 200 includes a tube 210, and a handrail surface tube 100 is sleeved on the outside of the tube 210. One of the inner wall of the handrail surface tube 100 and the outer wall of the tube 210 is provided with a mounting groove 110, and the other of the inner wall of the handrail surface tube 100 and the outer wall of the tube 210 is provided with an anti-rotation structure 300, forming a circumferential limiting fit between the handrail surface tube 100 and the tube 210 to restrict relative rotation between them. Specifically, in this embodiment, the inner wall of the handrail surface tube 100 is provided with a mounting groove 110, and the outer wall of the tube 210 is provided with a detachable anti-rotation structure 300.

[0049] Furthermore, the outer wall of the handrail body 200 or the inner wall of the handrail surface tube 100 is provided with a snap-fit ​​structure, and the anti-rotation structure 300 is detachably provided on the handrail surface tube 100 or the handrail body 200 through the snap-fit ​​structure.

[0050] The snap-fit ​​structure includes a first opening 211 provided on either the handrail surface tube 100 or the handrail body 200; in this embodiment, specifically, the snap-fit ​​structure includes a first opening 211 provided on the tube body 210.

[0051] The anti-rotation structure 300 includes at least a base 310 and a snap-fit ​​part fixed on the base 310, the snap-fit ​​part being able to snap into the first opening 211.

[0052] This invention provides a snap-fit ​​structure on the outer wall of the handrail body 200 or the inner wall of the handrail surface tube 100, allowing the anti-rotation structure 300 to be detachably mounted on the handrail surface tube 100 or the handrail body 200 via the snap-fit ​​structure. This facilitates installation and disassembly, reducing the difficulty of installation and maintenance. Furthermore, the snap-fit ​​part can engage with the first opening 211, enhancing the connection stability between the anti-rotation structure 300 and the handrail surface tube 100 or the handrail body 200, preventing the anti-rotation structure 300 from loosening or falling off during use, and ensuring the long-term stability and reliability of the handrail.

[0053] In this embodiment, the base 310 is a strip-shaped structure that is adapted to the mounting groove 110 and extends axially along the handrail surface tube 100 or the handrail body 200. The base 310 can be embedded in the mounting groove 110. The base 310 is provided with a plurality of snap-fit ​​parts, which are vertically disposed on the base 310. The snap-fit ​​structure is provided with a plurality of first openings 211, which are axially spaced on the handrail surface tube 100 or the handrail body 200.

[0054] The base 310 of this utility model is a strip-shaped structure adapted to the mounting groove 110 and extends along the axial direction, so that the anti-rotation structure 300 can better adapt to the shape and size of the mounting groove 110 and improve the stability of the anti-rotation structure 300 in the mounting groove 110; the anti-rotation structure 300 can form a multi-point connection with the handrail surface tube 100 or the handrail body 200 through multiple snap-fit ​​parts, which improves the reliability and stability of the connection.

[0055] Preferably, the snap-fit ​​part is a rib 320, and the horizontal cross-sectional width of the end of the rib 320 near the base 310 is greater than the horizontal cross-sectional width of the end away from the base 310; the distribution position of the rib 320 corresponds to the distribution position of the first opening 211.

[0056] In this invention, the horizontal cross-sectional width of the end of the rib 320 near the base 310 is greater than the horizontal cross-sectional width of the end away from the base 310, making the fit between the rib 320 and the first opening 211 tighter, improving the snap-fit ​​effect and enhancing the anti-rotation performance of the anti-rotation structure 300. Furthermore, the distribution position of the rib 320 corresponds to the distribution position of the first opening 211, ensuring the precise positioning and fit of the anti-rotation structure 300 during installation, avoiding installation problems caused by positional deviations, and improving the accuracy and reliability of installation.

[0057] Preferably, the number of first openings 211 is equal to the number of ribs 320.

[0058] In this embodiment, when there are multiple ribs 320, the spacing between adjacent ribs 320 is adapted to the spacing between corresponding adjacent first openings 211, allowing the ribs 320 to extend into the corresponding first openings 211 to form a limiting fit. It should be noted that the spacing between adjacent ribs 320 is equally and / or proportionally set, and correspondingly, the spacing between adjacent first openings 211 is equally and / or proportionally set. The cooperation of multiple ribs 320 and multiple first openings 211 in this invention forms a multi-point limiting structure. This multi-point limiting method can distribute the force more evenly, making the axial and circumferential constraints between the handrail surface tube 100 and the tube body 210 more uniform and stable, thereby more effectively preventing the handrail surface tube 100 from rotating, further optimizing the structural performance of the handrail, and improving its stability in actual use.

[0059] Preferably, the anti-rotation structure 300 includes a base 310 and three ribs 320 fixed on the base 310, with the spacing between adjacent ribs 320 being equal.

[0060] The distribution of the reinforcing ribs 320 in this invention corresponds to the distribution of the first openings 211. Furthermore, when there are multiple reinforcing ribs 320, the spacing between adjacent ribs 320 matches the spacing of the corresponding first openings 211, allowing the reinforcing ribs 320 to smoothly and accurately extend into their respective openings, forming a stable limiting fit. This not only ensures the installation precision and positioning accuracy of the anti-rotation structure 300, but also effectively avoids the risk of rotation due to improper installation, further improving the stability and safety of the handrail.

[0061] In this embodiment, the outer surface of the handrail tube 100 is provided with an anti-slip structure 120. The anti-slip structure 120 includes at least one of the following: protrusions, grooves, holes, and particles. The arrangement of the anti-slip structure 120 includes at least one of the following: axial arrangement along the handrail tube 100, circumferential arrangement along the handrail tube 100, staggered arrangement along the handrail tube 100, and dense arrangement in a local area of ​​the handrail tube 100 (e.g., dense arrangement in key gripping areas).

[0062] This invention provides an anti-slip structure 120, such as protrusions, grooves, holes, or particles, on the outside of the handrail surface tube 100. These anti-slip structures 120 can effectively increase the friction between the user's hand and the handrail surface tube 100, thereby preventing the user from slipping when holding the handrail with wet or slippery hands, reducing the risk of falls caused by slipping, greatly improving the safety of the handrail in actual use, and enhancing the user experience.

[0063] Preferably, the anti-slip structure 120 is a strip-shaped protrusion, and is arranged along the axial direction of the handrail surface tube 100.

[0064] In this embodiment, the handrail body 200 also includes washers 260, which are sleeved on both ends of the tube 210. The handrail surface tube 100 abuts against the wall-locking elbow assembly 220 through the washers 260.

[0065] This utility model uses washers 260, which are sleeved on both ends of the pipe body 210 and abut against the wall-locking elbow assembly 220, to prevent wear caused by the pipe body 210 and the elbow assembly abutting against each other, thereby further improving the service life of the handrail.

[0066] Please see Figure 4 and Figure 5 The handrail body 200 of this utility model also includes two wall-locking elbow assemblies 220 respectively disposed at both ends of the tube body 210; the wall-locking elbow assembly 220 includes at least a bent pipe 221, a gasket 230 and a bolt 240;

[0067] The bend 221 has a first nut insert 221a inside one end and a bolt insert 221b inside the other end. The washer 230 has a second through hole 231.

[0068] Bolt 240 is inserted into the second opening 231 in sequence and screwed into the first nut insert 221a to fix the washer 230 and the bend 221.

[0069] This utility model, through the tight fit between the bolt 240 and the first nut insert 221a, can firmly fix the washer 230 and the bend 221 of the wall-locking elbow assembly 220, thereby enhancing the fixing effect and overall stability of the handrail.

[0070] In this embodiment, a second nut insert 210a is provided inside both ends of the pipe body 210, and a bolt insert 221b is screwed to the second nut insert 210a to fix the pipe body 210 and the bend 221.

[0071] Preferably, the first nut insert 221a is formed by embedding a nut inside the bent tube 221 during the injection molding process of the bent tube 221, and the bolt insert 221b is formed by embedding a bolt 240 inside the bent tube 221 during the injection molding process of the bent tube 221. The second nut insert 210a is formed in a similar manner.

[0072] This invention provides a fixed connection between the pipe body 210 and the bend 221 by providing second nut inserts 210a inside both ends of the pipe body 210 and screwing bolt inserts 221b to the second nut inserts 210a. This connection method further enhances the connection strength and stability between the pipe body 210 and the wall-locking elbow assembly 220. Compared with simple welding or other connection methods, it provides a more uniform stress distribution, ensuring a tight bond between the pipe body 210 and the bend 221 that is not easily loosened. This effectively prevents loosening or damage to the connection due to long-term use or external forces, thus improving the service life and reliability of the handrail.

[0073] In this embodiment, the wall-locking elbow assembly 220 also includes an expansion fastener 250, and the gasket 230 is also provided with a third through hole 232.

[0074] The expansion fastener 250 includes a mating expansion head 251 and a locking member 252. The locking member 252 extends into the third opening 232 and is fixedly connected to the expansion head 251, forming a two-way locking structure that extends into the gasket 230 and the external mounting hole (e.g., mounting hole on a wall or floor).

[0075] Preferably, the locking element 252 is a screw.

[0076] This utility model's wall-locking elbow assembly 220 includes a cooperating expansion head 251 and a locking member 252. The locking member 252 extends into the third opening 232 on the washer 230 and is fixedly connected to the expansion head 251. The expansion fastener 250 can extend into the wall and, through the principle of expansion, forms a tight frictional fixing effect with the wall, thereby establishing a more solid connection between the handrail and the wall. This effectively enhances the stability of the handrail on the wall, prevents the handrail from loosening or shifting due to external forces, and provides users with a safer and more reliable climbing environment.
