Description

Technical Field

[0001] The utility model relates to the technical field of handrails, in particular to a barrier-free anti-slip handrail. Background Art

[0002] Handrails are protrusions that are usually installed on stairs, railings, balconies, etc., which are both practical and decorative. They are components for people to hold on to when walking. The application scenarios of handrails are also very wide. For example, in barrier-free places such as corridors, especially for people with inconvenient walking or disabled people, the anti-slip performance of handrails is a key consideration for manufacturers. To solve this problem, the conventional operation method is to put a nylon sleeve on the inner core of the handrail to increase the friction with the hand through the nylon sleeve, thereby playing an anti-slip role. However, this method cannot avoid the problem of radial rotation of the nylon sleeve on the inner core pipe. It relies more on the friction between the inner wall of the nylon sleeve and the inner core pipe. Once the hand grip is greater than the friction, the nylon sleeve is easily rubbed. Moreover, as time goes by, the nylon sleeve is deformed, and the gap between it and the inner core pipe becomes larger and larger, making it impossible to fix the nylon sleeve. Instead, it affects people's grip on the handrail. It often happens that the elderly or disabled people fall down when they grip the handrail. Just like the nylon sleeve on the bus handrail, after a period of use, it has no anti-slip effect at all. In order to increase the friction between the nylon sleeve and the inner core pipe, the manufacturer chooses to add a number of vertical ribs or bumps on the inner core pipe to increase the friction by increasing the contact area. However, this method still cannot solve the problem of rotation of the nylon sleeve once the hand grip is greater than the friction. Utility Model Content

[0003] The utility model provides a barrier-free anti-skid handrail to make up for the deficiencies of the prior art. The utility model has a reasonable structural design and is easy to operate. A snap-on connection method is adopted, so that the nylon tube sleeve can be firmly fixed on the outer wall of the inner core main tube. Even if the hand gripping force is greater than the friction between the nylon tube sleeve and the inner core main tube, the radial rotation of the nylon tube sleeve can be effectively prevented. On the other hand, deformation of the nylon tube sleeve caused by long-term rotation is avoided, thereby ensuring the normal grip of the elderly, avoiding falls caused by the slipping of the nylon tube sleeve, extending the service life of the handrail, and solving many problems existing in the prior art.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A barrier-free anti-skid handrail comprises an inner core main pipe and a nylon pipe sleeve. A limiting mechanism matched with the nylon pipe sleeve is arranged on the inner core main pipe, the limiting mechanism comprises at least one clamping keel arranged on the outer wall of the inner core main pipe along the length direction of the inner core main pipe, a clamping groove matched with the clamping keel is arranged on the inner wall of the nylon pipe sleeve corresponding to the position of the clamping keel; and a plurality of anti-skid rubber strips are arranged on the outer wall of the nylon pipe sleeve.

[0006] Optionally, the clamping keels are in three groups and are evenly arranged along the circumferential direction of the inner core main pipe.

[0007] Optionally, the inner core main tube comprises an inner tube and an outer tube which are coaxially arranged, and the inner tube is connected to the outer tube via a plurality of reinforcing ribs arranged along the circumferential direction thereof.

[0008] Optionally, the limiting mechanism includes at least one groove keel arranged on the outer wall of the inner core main pipe along the length direction of the inner core main pipe, and a clamping convex strip matching the groove keel is provided on the inner wall of the nylon tube sleeve corresponding to the position of the groove keel.

[0009] The utility model adopts the above technical scheme, and has the advantages of reasonable structural design and convenient operation. It adopts a snap-on connection method, which can firmly fix the nylon tube sleeve on the outer wall of the inner core main tube. Even if the hand gripping force is greater than the friction between the nylon tube sleeve and the inner core main tube, it can effectively prevent the nylon tube sleeve from rotating radially. On the other hand, it avoids deformation of the nylon tube sleeve due to long-term rotation, thereby ensuring the normal grip of the elderly, avoiding falls caused by the slipping of the nylon tube sleeve, and extending the service life of the handrail.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In the description of this specification, the descriptions with reference to the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" and the like mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

[0018] Embodiment 1:

[0019] like Figure 1-3As shown, a barrier-free anti-slip handrail includes an inner core main pipe 1 and a nylon pipe sleeve 2. A limiting mechanism matching with the nylon sleeve 2 is provided on the inner core main pipe 1, and the limiting mechanism includes at least one clamping keel 3 arranged on the outer wall of the inner core main pipe 1 along the length direction of the inner core main pipe 1, and a clamping groove 4 matching with the clamping keel 3 is provided on the inner wall of the nylon pipe sleeve 2 corresponding to the position of the clamping keel 3; and a plurality of anti-slip rubber strips 5 are provided on the outer wall of the nylon pipe sleeve 2.

[0020] Optionally, the clamping keels 3 are in three groups and are evenly arranged along the circumference of the inner core main tube 1. The cross-section of the three groups of clamping keels 3 is triangular, which has the highest stability and can maximize the support effect of the inner core main tube 1 on the nylon tube sleeve 2 from all angles.

[0021] Optionally, the inner core main tube 1 comprises an inner tube 101 and an outer tube 102 which are coaxially arranged, and the inner tube 101 is connected to the outer tube 102 via a plurality of reinforcing ribs 103 arranged along the circumferential direction thereof.

[0022] When the handrail is in use, people hold the nylon tube sleeve 2 of the handrail with their hands, and the friction between the hands and the anti-skid rubber strips 5 can be increased through the anti-skid rubber strips 5 to prevent slipping as much as possible. When the elderly or disabled hold the handrail, they will bear their own body weight, and their holding force will be greater, so that the nylon tube sleeve 2 is forced to rotate on the inner core main tube 1. The nylon sleeve 2 is preferably fixed to the outer wall of the inner core main pipe 1 by the snap-fitting keel 3 and the snap-fitting groove 4. On the other hand, the deformation of the nylon sleeve 2 caused by long-term rotation is avoided, thereby ensuring the normal grip of the elderly, avoiding the situation of falling due to the slipping of the nylon sleeve 2, extending the service life of the handrail, and solving many problems existing in the prior art.

[0023] Embodiment 2:

[0024] like Figure 4As shown: Optionally, the limiting mechanism includes at least one groove keel 6 arranged on the outer wall of the inner core main pipe 1 along the length direction of the inner core main pipe 1, and a clamping convex strip 7 matching the groove keel 6 is arranged on the inner wall of the nylon tube sleeve 2 at the position corresponding to the groove keel 6. This arrangement can firmly fix the nylon tube sleeve 2 on the outer wall of the inner core main pipe 1 through the mutual cooperation of the groove keel 6 and the clamping convex strip 7, and even if the hand grip force is greater than the friction between the nylon tube sleeve 2 and the inner core main pipe 1, it can effectively prevent the nylon tube sleeve 2 from rotating radially, solving many problems existing in the prior art.
