Description

Technical Field

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

[0002] Handrails, as a common auxiliary support device, are widely used in homes, hospitals, nursing homes, and other places, especially in bathroom environments, providing necessary support and assistance for the elderly, disabled, or those with mobility impairments. However, existing bathroom handrail designs still have some shortcomings in practical applications. Traditional bathroom handrails usually adopt a one-piece design. While this design is simple and straightforward in structure, the large size of the one-piece handrail results in a large packaging volume, occupies a lot of space, and thus leads to relatively high logistics and transportation costs. In addition, the installation and disassembly of this type of handrail are often complex and time-consuming, making it difficult to flexibly adjust to specific environments and individual needs. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a handrail that is portable, easy to install and remove, saving logistics costs and improving user experience.

[0004] A handrail according to a first aspect of the present invention includes:

[0005] The L-shaped connecting pipe includes a first connecting section and a second connecting section that are perpendicularly connected to each other, and the ends of the first connecting section and the second connecting section are respectively provided with locking mechanisms;

[0006] The tube assembly includes a first tube and a second tube. The ends of the first tube and the second tube are provided with engaging portions. The engaging portions are adapted to the locking mechanism. The locking mechanism can be detachably connected to the engaging portions along the axial direction.

[0007] A handrail according to an embodiment of the present invention has at least the following beneficial effects: the locking mechanisms at the ends of the first and second connecting sections are adapted to the engaging portions on the tube assembly, achieving a detachable connection along the axial direction. This design greatly simplifies the installation process of the handrail, allowing users to quickly and easily assemble or disassemble it without the need for complex tools. The locking mechanism ensures a firm connection between the first and second tubes and the L-shaped connecting tube, preventing loosening or separation caused by vibration or external force during daily use. This not only enhances the overall stability of the handrail but also extends its service life. Due to the L-shaped connecting tube design, the position and direction of the handrail can be flexibly adjusted according to actual needs, thereby making more effective use of limited space. It is especially suitable for places with special spatial layout requirements, such as residences, hospitals, and nursing homes. The modular design allows for the separate transportation of components, which greatly reduces packaging volume and transportation costs.

[0008] According to some embodiments of the present invention, the locking mechanism includes a guide seat, a locking piece, and an elastic element arranged sequentially. The guide seat is provided with a guide slope, the locking piece is movably mounted on the guide slope, the engaging part includes a square shaft, the guide seat is provided with a first through groove, the locking piece is provided with a second through groove, and the elastic element drives the locking piece to move toward the guide seat.

[0009] In the unlocked state, the locking piece is flush with the square axis to make the first through slot and the second through slot connected;

[0010] In the locked state, the locking piece is flush with the guide ramp to close the first and second through slots. This ensures that in the unlocked state, the locking piece is flush with the square axis, allowing the first and second through slots to connect, thus enabling quick unlocking. This design greatly simplifies user operation, allowing the unlocking or locking process to be completed without complicated steps. When in the locked state, the locking piece is flush with the guide ramp, closing the first and second through slots and forming a stable locking mechanism. This not only prevents unintended unlocking due to accidental collisions or external forces but also enhances the security of the entire connection system.

[0011] According to some embodiments of this utility model, the engaging part further includes an outer bushing, which is disposed on one side of the square shaft. The locking mechanism further includes an inner bushing, with the guide seat and the locking piece disposed within the inner bushing. The outer bushing and the inner bushing are mutually adapted. The design of the outer and inner bushings provides an additional support layer for the entire locking mechanism, increasing the overall rigidity and stability of the connection point. This double-layer sleeve design can effectively resist external forces from all directions, ensuring that the handrail is not prone to loosening or deformation during use, thereby improving the stability and durability of the overall structure.

[0012] According to some embodiments of this utility model, the outer bushing is provided with a first reset hole, and the inner bushing is provided with a second reset hole. When the outer bushing is fully installed on the inner bushing, the centers of the first reset hole and the second reset hole are collinear. When unlocking is required, the reset hole acts on the locking piece, causing it to move precisely to a position flush with the square shaft, ensuring that the first through groove and the second through groove are connected, forming an exit channel for the square shaft.

[0013] According to some embodiments of this utility model, the first reset hole and the second reset hole are provided with decorative covers. This can prevent dust, moisture, and other impurities from entering the interior of the reset holes, thereby avoiding potential damage to the locking mechanism or affecting its normal function.

[0014] According to some embodiments of this utility model, the surfaces of the square shaft, the first through groove, and the second through groove are provided with anti-slip teeth. This makes the contact between the square shaft and the first and second through grooves more stable, ensuring a secure connection and preventing loosening.

[0015] According to some embodiments of this utility model, the square shaft is a wedge-shaped block, and the first through groove and the second through groove are wedge-shaped grooves. The wedge structure can disperse pressure when subjected to force, and the connection can remain stable even under large external forces, reducing the risk of damage caused by external impacts.

[0016] According to some embodiments of this utility model, two locking pieces are provided, arranged side by side. By using two locking pieces arranged side by side, the stability and load-bearing capacity of the locking mechanism can be significantly increased. Compared with the design of a single locking piece, the double locking pieces can distribute the load more evenly, reduce the risk of failure caused by local stress concentration, and thus ensure a more robust and reliable connection.

[0017] According to some embodiments of this utility model, the surfaces of the L-shaped connecting tube, the first tube body, and the second tube body are provided with staggered diamond-shaped anti-slip protrusions. This improves safety and increases the tactile comfort of the contact surface. Compared with a smooth surface, the slightly raised texture can reduce the pressure points when the palm directly contacts hard materials, dispersing pressure and making the grip more comfortable and natural.

[0018] According to some embodiments of this utility model, the first tube and the second tube are straight tubes. Straight tubes can further save space in logistics transportation and reduce logistics costs.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] Reference Figures 1 to 4 A handrail, comprising:

[0031] The L-shaped connecting pipe 100 includes a first connecting section 130 and a second connecting section 140 that are perpendicularly connected to each other, and the ends of the first connecting section 130 and the second connecting section 140 are respectively provided with locking mechanisms.

[0032] The tube assembly includes a first tube 110 and a second tube 120. The ends of the first tube 110 and the second tube 120 are provided with engaging portions. The engaging portions are adapted to a locking mechanism. The locking mechanism can form a detachable connection with the engaging portions along the axial direction.

[0033] The locking mechanisms at the ends of the first connecting section 130 and the second connecting section 140 are adapted to the engaging parts on the tube assembly, achieving a detachable connection along the axial direction. This design greatly simplifies the installation process of the handrail, allowing users to quickly and easily assemble or disassemble it without the need for complex tools. The locking mechanism ensures a firm connection between the first tube 110 and the second tube 120 and the L-shaped connecting tube 100, preventing loosening or separation caused by vibration or external force during daily use. This not only enhances the overall stability of the handrail but also extends its service life. Due to the design of the L-shaped connecting tube 100, the position and direction of the handrail can be flexibly adjusted according to actual needs, thereby making more effective use of limited space. It is especially suitable for places with special spatial layout requirements, such as residences, hospitals, and nursing homes. The modular design allows for the separate transportation of components, which greatly reduces packaging volume and transportation costs.

[0034] The locking mechanism includes a guide seat 180, a locking piece 250 and an elastic element 190 arranged in sequence. The guide seat 180 is provided with a guide slope. The locking piece 250 is movably installed on the guide slope. The engaging part includes a square shaft 170. The guide seat 180 is provided with a first through groove 230. The locking piece 250 is provided with a second through groove 240. The elastic element 190 drives the locking piece 250 to move toward the guide seat 180.

[0035] In the unlocked state, the locking piece 250 is flush with the square shaft 170 so that the first through slot 230 and the second through slot 240 are connected;

[0036] In the locked state, the locking piece 250 is flush with the guide ramp, closing the first through slot 230 and the second through slot 240. This ensures that in the unlocked state, the locking piece 250 is flush with the square shaft 170, allowing the first through slot 230 and the second through slot 240 to conduct, thus enabling quick unlocking. This design greatly simplifies user operation, allowing the unlocking or locking process to be completed without complicated steps. When in the locked state, the locking piece 250 is flush with the guide ramp, closing the first through slot 230 and the second through slot 240, forming a stable locking mechanism. This not only prevents unintended unlocking due to accidental collisions or external forces but also enhances the security of the entire connection system.

[0037] The engaging part also includes an outer bushing 150, which is disposed on one side of the square shaft 170. The locking mechanism also includes an inner bushing 160, a guide seat 180, and a locking piece 250 disposed within the inner bushing 160. The outer bushing 150 and the inner bushing 160 are mutually compatible. The design of the outer bushing 150 and the inner bushing 160 provides an additional support layer for the entire locking mechanism, increasing the overall rigidity and stability of the connection point. This double-layer sleeve design can effectively resist external forces from all directions, ensuring that the handrail is not prone to loosening or deformation during use, thereby improving the stability and durability of the overall structure.

[0038] The outer bushing 150 is provided with a first reset hole 210, and the inner bushing 160 is provided with a second reset hole 220. When the outer bushing 150 is fully installed on the inner bushing 160, the centers of the first reset hole 210 and the second reset hole 220 are collinear. When unlocking is required, the reset hole acts on the locking piece, causing it to move precisely to a position flush with the square shaft 170, ensuring that the first through groove 230 and the second through groove 240 are connected, forming an exit channel for the square shaft 170.

[0039] The first reset hole 210 and the second reset hole 220 are provided with decorative covers 200. These covers prevent dust, moisture, and other impurities from entering the reset holes, thereby avoiding potential damage to the locking mechanism or affecting its normal function.

[0040] The surfaces of the square shaft 170, the first through groove 230, and the second through groove 240 are provided with anti-slip teeth. This makes the contact between the square shaft 170 and the first through groove 230 and the second through groove 240 more stable, the connection more secure, and less prone to loosening.

[0041] The square shaft 170 is a wedge-shaped block, and the first through groove 230 and the second through groove 240 are wedge-shaped grooves. The wedge structure can disperse pressure when subjected to force, and the connection can remain stable even under large external forces, reducing the risk of damage caused by external impacts.

[0042] There are two locking plates 250, arranged side by side. By using two locking plates arranged side by side, the stability and load-bearing capacity of the locking mechanism can be significantly increased. Compared with the design of a single locking plate, the load can be distributed more evenly, reducing the risk of failure caused by local stress concentration, thereby ensuring a more robust and reliable connection.

[0043] The surfaces of the L-shaped connecting tube 100, the first tube body 110, and the second tube body 120 are provided with staggered diamond-shaped anti-slip protrusions. This improves safety and increases the tactile comfort of the contact surface. Compared to a smooth surface, the slightly raised texture reduces the pressure points when the palm directly contacts hard materials, dispersing pressure and making the grip more comfortable and natural. The first tube body 110 and the second tube body 120 are straight tubes. Straight tubes further save space during logistics and transportation, reducing logistics costs.

[0044] In this embodiment, the L-shaped connecting pipe 100 includes a first connecting section 130 and a second connecting section 140 that are perpendicular to each other. Locking mechanisms are provided at both ends. Each locking mechanism consists of a guide seat 180, a locking piece 250, and an elastic element 190. The guide seat 180 has a guide slope, and the locking piece 250 is movably mounted on the guide slope. Specifically, this embodiment provides two locking pieces 250 arranged side-by-side to enhance stability and load-bearing capacity.

[0045] The guide seat 180 has a first through groove 230, and the locking piece 250 has a second through groove 240. The elastic element 190 drives the locking piece 250 to move toward the guide seat 180. When in the unlocked state, the locking piece 250 is flush with the square shaft 170, making the first through groove 230 and the second through groove 240 connected; when in the locked state, the locking piece 250 is flush with the guide slope, closing the first through groove 230 and the second through groove 240.

[0046] The engaging part includes a square shaft 170, designed as a wedge-shaped block, with an outer bushing 150 located on one side of the square shaft 170. The locking mechanism also includes an inner bushing 160, a guide seat 180, and a locking piece 250 located within the inner bushing 160. The outer bushing 150 and the inner bushing 160 are mutually fitted and are respectively provided with a first reset hole 210 and a second reset hole 220. When fully installed, their centers are collinear, and decorative covers 200 are provided above these holes to protect them from external influences while maintaining aesthetics.

[0047] The surfaces of the L-shaped connecting pipe 100, the first pipe body 110, and the second pipe body 120 are provided with staggered diamond-shaped anti-slip protrusions, which increase friction and improve safety and hand comfort. The first pipe body 110 and the second pipe body 120 adopt a straight pipe design, which facilitates transportation and storage, saves space, and reduces logistics costs.

[0048] During installation, first align the engaging portions at the ends of the first tube 110 and the second tube 120 with the locking mechanism on the L-shaped connecting tube 100, and gently push them in until the locking piece 250 automatically springs back to the locking position under the action of the elastic element 190, thus completing the installation.

[0049] During the unlocking operation, use a tool to apply appropriate pressure through the first reset hole 210 and the second reset hole 220 to push the locking piece 250 to the unlock position, and then the first tube 110 or the second tube 120 can be easily pulled out for adjustment or replacement.

[0050] By increasing the number of locking mechanisms and optimizing their design, the robustness and stability of the handrail connections are ensured, reducing the risk of accidental loosening. Diamond-shaped anti-slip protrusions enhance grip comfort while simplifying installation and disassembly, making it convenient for users. The straight tube design not only reduces manufacturing costs but also optimizes logistics efficiency, aligning with modern environmental protection principles.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
