Specifically, the grab rail 400 may be made of a metal material such as stainless steel or aluminum alloy, so as to ensure the strength requirement of the safety handrail and improve the safety of users during use. However, it can be appreciated that metallic materials such as stainless steel are relatively cool when used in low temperature environments (e.g., winter), and the user experiences poor touch and cool when using the materials. The outer sleeve 500 made of non-metal material is further sleeved outside the grab rail 400 in this embodiment, so as to avoid too low external temperature of the grab rail 400 in low temperature environment and improve the experience of the user.

Referring to fig. 11 and 12, fig. 12 is a cross-sectional view of fig. 10, in which the inner wall of the outer sleeve 500 has a third limiting plane 520, the third limiting plane 520 extends to the end surface along the axial direction of the outer sleeve, and the second limiting plane 430 further includes a third limiting structure 420, and when the outer sleeve 500 is sleeved on the outer wall of the grab bar 400, the third limiting plane 520 and the second limiting plane 430 are mutually attached, thereby preventing the outer sleeve 500 from rotating relative to the grab bar 400. Specifically, it can be appreciated that the second limiting plane 430 is formed on the outer wall of the grab rail 400 to form the second limiting structure 410 and the third limiting structure 420, so that the structure of the grab rail 400 is simpler, the processing cost is lower, and the manufacturing cost of the safety handrail of the embodiment is reduced.

Referring to fig. 5 and 7, fig. 5 is a schematic structural view of the second connecting member in fig. 4, and in some embodiments, the fixing base 200 has a second connecting hole 240 (as shown in fig. 7), and the second connecting member 320 is screwed to an inner wall of the second connecting hole 240. Specifically, the inner wall of the second connecting hole 240 is provided with an internal thread, the second connecting piece 320 is provided with an external thread (as shown in fig. 5), the second connecting piece 320 is connected with the fixing base 200 by threads, and the length of the second connecting piece 320 exposed out of the fixing base 200 can be adjusted by adjusting the length of the second connecting piece 320 screwed into the second connecting hole 240, so that the distance between the accommodating groove 321 and the end of the fixing base 200 facing the grab bar 400 can be adjusted, and the grab bar 400 can be abutted against the fixing base 200 when being locked on the second connecting piece 320 by the limiting piece 330, thereby improving the stability of the grab bar 400.

Referring to fig. 4 and fig. 6, fig. 6 is a schematic structural diagram of the elastic clamping member in fig. 4, and in some embodiments, the limiting member 330 and the elastic member 340 are integrally formed into an elastic clamping member 350, and the elastic clamping member 350 is disposed in the accommodating groove 321. For example, the elastic clamping member 350 is configured as a metal spring, and one end of the metal spring is disposed in the accommodating groove 321 and partially protrudes out of the accommodating groove 321 in a natural stretching state. It can be appreciated that, by the elastic clamping member 350 with an integral structure, not only the production of parts in the manufacturing process can be reduced, but also the assembly steps can be reduced, thereby reducing the manufacturing cost of the safety handrail of the embodiment. Further, the metal elastic sheet may be configured as an arch structure, when in installation, both ends of the metal elastic sheet are in contact with the bottom wall of the accommodating groove 321, both ends of the metal elastic sheet are distributed along the axial direction of the second connecting piece 320, and in a natural stretching state, the metal elastic sheet is partially exposed out of the accommodating groove 321. When the second connecting piece 320 extends into the first connecting hole 311, the side surface of the arch structure is an arc surface, so that the arch structure can automatically deform towards the axis of the second connecting piece 320 when being propped against the hole edge of the first connecting hole 311, without manual pressing, and the connection between the first connecting piece 310 and the second connecting piece 320 is simpler.

It can be appreciated that, in the above embodiment, in order to prevent the elastic clamping member 350 from falling from the accommodating groove 321 during the installation process of the second connecting member 320 and the first connecting member 310, the elastic clamping member 350 needs to be fixedly connected with the second connecting member 320, or the opening of the accommodating groove 321 needs to be upward, so that the assembling step of the safety handrail of the present embodiment, that is, the connecting step between the elastic clamping member 350 and the second connecting member 320, or the step of adjusting the notch direction of the accommodating groove 321, is increased. Based on this, in order to improve the assembly efficiency of the safety handrail of the present embodiment, the accommodating groove 321 has a profile extending along the circumferential direction of the second connecting member 320 (as shown in fig. 5), the radian of the accommodating groove 321 is greater than pi/2, the elastic clamping member 350 is in an annular structure (as shown in fig. 6), the radian of the elastic clamping member 350 is greater than pi/2, the elastic clamping member 350 is clamped in the accommodating groove 321, no fixed connection is required between the elastic clamping member 350 and the second connecting member 320, and no adjustment of the notch direction of the accommodating groove 321 is required, so that the elastic clamping member 350 can be ensured not to fall off. Specifically, the elastic clamping member 350 is in an annular structure, the two ends of the elastic clamping member 350 form the bayonet 352, and in the assembling process, the elastic clamping member 350 is forced to deform the elastic clamping member 350 to expand the bayonet 352, so that the elastic clamping member 350 is sleeved in the accommodating groove 321 of the second connecting member 320, the second connecting member 320 extends into the first connecting hole 311, and meanwhile, the elastic clamping member 350 is extruded along the radial direction of the second connecting member 320, so that the elastic clamping member 350 extends into the first connecting hole 311 along with the second connecting member 320.

Referring to fig. 6, the inner wall or the outer portion of the elastic catching member 350 is provided with a groove 351 on the basis of the above-described embodiment. Specifically, it can be appreciated that by providing the groove 351 on the elastic clamping member 350, the thickness of the elastic clamping member 350 at the groove 351 can be reduced, so that the elastic clamping member 350 is easier to deform, so that the elastic clamping member 350 can be more easily sleeved on the second connecting member 320, and can also more easily extend into the first connecting hole 311, so that the safety handrail of the embodiment is easier to assemble. Similarly, in some embodiments, the inner wall or the outer portion of the elastic clamping member 350 is provided with the groove 351, and further, the groove 351 of the inner wall and the groove 351 of the outer wall are disposed opposite to each other, so that the thickness of the elastic clamping member 350 at the groove 351 is thinner, so that the elastic clamping member 350 is more deformable.

It should be noted that, the thickness of the elastic clamping member 350 is reduced by adopting the form of the groove 351 instead of directly adopting the thinner elastic clamping member 350, so as to ensure that when the elastic clamping member 350 is clamped in the clamping groove 312, the first connecting member 310 and the second connecting member 320 have sufficient contact areas with the elastic clamping member 350, thereby improving the reliability of the elastic clamping member 350.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
