Description

Technical Field

[0001] The present application relates to the field of handrails, and in particular to a railing handrail with adjustable pole distance. Background Art

[0002] Railings are facilities installed in buildings, bridges, stairs and other places to support and protect people's safety. They are usually composed of handrails and supporting structures, which can be made of metal, wood, plastic and other materials. In architectural design, railings are also an important decorative element that can enhance the beauty and practicality of the building.

[0003] A railing handrail is disclosed in the related art, referring to Figure 1 , including a gate-shaped main rod 1, on which a plurality of auxiliary rods 2 are evenly arranged. Both the auxiliary rod 2 and the main rod 1 are hollow inside and have a circular tubular cross-section. The auxiliary rod 2 and the main rod 1 are usually assembled by welding.

[0004] Since the auxiliary rod is welded to the main rod, the distance between two adjacent auxiliary rods cannot be adjusted. Workers usually can only increase the number of auxiliary rods to ensure the protective distance, resulting in a large number of auxiliary rods used and obvious deficiencies. Utility Model Content

[0005] In order to improve the problem that the number of auxiliary rods used cannot be flexibly adjusted, the present application provides a railing handrail with adjustable rod distance.

[0006] The present application provides a railing handrail with adjustable pole distance, which adopts the following technical solution:

[0007] A railing handrail with adjustable pole distance comprises a main pole and a plurality of auxiliary poles. A sliding groove is provided on the top of the main pole, and the ends of the auxiliary poles extend from the sliding groove into the main pole and slideably cooperate with the main pole.

[0008] By adopting the above technical solution, workers manually slide the auxiliary rods according to the actual application site of the railing handrails to adjust the distance between two adjacent auxiliary rods, and then use the appropriate number of auxiliary rods. On the one hand, it can improve the applicability of the railing handrails to different application scenarios, and on the other hand, it can save the use of auxiliary rods.

[0009] Optionally, a positioning ring located inside the main rod is provided at the end of the auxiliary rod, the axis of the positioning ring is perpendicular to the axis of the auxiliary rod, and the outer side wall of the positioning ring is tightly attached to and slidably fits with the inner wall of the main rod.

[0010] By adopting the above technical solution, the positioning ring is in close contact with the inner wall of the main rod, thereby limiting the auxiliary rod to a certain extent, reducing the possibility of its tilting and twisting, and ensuring the stability of the overall assembly process of the railing handrail.

[0011] Optionally, a polytetrafluoroethylene layer is arranged on the inner wall of the main rod.

[0012] By adopting the above technical solution, the friction coefficient of polytetrafluoroethylene is small, thereby improving the smoothness of the inner wall of the main rod, which is beneficial to improving the smoothness of workers manually sliding the positioning ring.

[0013] Optionally, the positioning ring is made of an elastic metal sheet, and the main rod is provided with a mounting notch for the positioning ring to be placed in.

[0014] By adopting the above technical solution, during installation, the worker manually flattens the positioning ring, inserts most of it into the main rod through the installation groove, and then releases it. The positioning ring automatically restores its deformation and presses against the inner wall of the main rod, so that the positioning ring is automatically constrained in the main rod.

[0015] Optionally, an elastic covering sheet for covering the installation slot is provided on the main rod.

[0016] By adopting the above technical solution, the elastic covering sheet covers the installation slot, thereby reducing the possibility of external impurities and garbage entering the main rod.

[0017] Optionally, a rivet head is riveted on the main rod, and the elastic covering sheet is rotatably sleeved on the rivet head.

[0018] By adopting the above technical solution, before disassembling the auxiliary rod, the worker first moves it to deform it and then rotates it, so as to offset the elastic cover sheet from the installation slot, thereby facilitating the disassembly and assembly of the auxiliary rod.

[0019] Optionally, the installation slot is opened on the main rod in an arc shape relative to the axis thereof, and the angle between the two ends of the installation slot in the arc direction and the axis of the main rod is not greater than 90°.

[0020] By adopting the above technical solution, the connection strength of the main rod relative to the installation groove is guaranteed, and the overall stability of the railing handrail is enhanced.

[0021] Optionally, anti-slip patterns are arranged on the elastic covering sheet.

[0022] By adopting the above technical solution, the arrangement of the anti-slip pattern makes it convenient for workers to manually move the elastic covering sheet.

[0023] To sum up, the present application includes the following beneficial technical effects: workers manually slide the auxiliary rods according to the actual application site of the railing handrails to adjust the distance between two adjacent auxiliary rods, and then use an appropriate number of auxiliary rods. On the one hand, it can improve the applicability of the railing handrails to different application scenarios, and on the other hand, it can save the use of auxiliary rods.

[0028] The following is combined with Figure 2-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a railing handrail with adjustable pole distance.

[0030] Reference Figure 2 The pole-spacing adjustable railing handrail comprises a gate-shaped main pole 1, on which a plurality of mutually parallel auxiliary poles 2 are evenly spaced and arranged, and both the auxiliary poles 2 and the main pole 1 are hollow inside and have a circular tubular cross-section.

[0031] Reference Figure 2 and Figure 3 A slide groove 101 is provided at the top of the main rod 1 along the arrangement direction of the plurality of auxiliary rods 2, and the end of the auxiliary rod 2 extends from the slide groove 101 into the main rod 1 and slidably cooperates with the main rod 1.

[0032] Each auxiliary rod 2 can slide relative to the main rod 1, so that workers can use a suitable number of auxiliary rods 2 and adjust the distance between two adjacent auxiliary rods 2 according to the actual application site requirements of the railing handrail. On the one hand, it can improve the applicability of the railing handrail to different scenes, and on the other hand, it can also save the use of auxiliary rods 2.

[0033] Reference Figure 2 and Figure 3 A positioning ring 3 located inside the main rod 1 is welded to the end of the auxiliary rod 2, the axis of the positioning ring 3 is perpendicular to the axis of the auxiliary rod 2, and the outer side of the positioning ring 3 is tightly attached to the inner wall of the main rod 1 and slides in cooperation.

[0034] Since the positioning ring 3 has a certain length relative to its circumference, the outer circumferential wall of the positioning ring 3 will have a larger area in contact with the inner wall of the main rod 1, and then the positioning ring 3 will have a certain limiting and restraining effect on the auxiliary rod 2, reducing the possibility of tilting and twisting of the auxiliary rod 2 during the overall assembly of the railing handrail.

[0035] Reference Figure 2 and Figure 3The inner wall of the main rod 1 is coated with a polytetrafluoroethylene layer. The friction coefficient of polytetrafluoroethylene is small, so the smoothness of the inner wall of the main rod 1 is improved, and the smoothness of the positioning ring 3 when moving in the main rod 1 is improved.

[0036] Reference Figure 2 and Figure 3 The positioning ring 3 is made of an elastic metal sheet, and a mounting slot 102 for the positioning ring 3 to be placed is provided on the main rod 1. The mounting slot 102 is provided on the main rod 1 in an arc shape relative to the circumferential direction of the axis thereof.

[0037] During installation, the worker manually flattens the positioning ring 3, inserts most of the ring body of the positioning ring 3 into the main rod 1 through the installation slot 102, and then loosens it. At this time, the positioning ring 3 automatically restores its deformation, so that the positioning ring 3 fits tightly against the inner wall of the main rod 1 by itself.

[0038] Reference Figure 2 and Figure 3 The angle between the two ends of the mounting slot 102 and the axis of the main rod 1 is not greater than 90°. This ensures the structural strength of the main rod 1 relative to the mounting slot 102 on the one hand, and reduces the possibility of the positioning ring 3 accidentally detaching from the main rod 1 from the mounting slot 102 due to force deformation on the other hand.

[0039] Reference Figure 2 and Figure 3 A rivet head 5 is riveted on the outer wall of the main rod 1 at a position next to the installation slot 102 , and an elastic covering sheet 4 for covering the installation slot 102 is rotatably sleeved on the rivet head 5 .

[0040] The elastic covering piece 4 covers the installation slot 102 , thereby reducing the possibility of large-scale garbage from the outside accidentally entering the main pole 1 .

[0041] Reference Figure 2 and Figure 3 The elastic cover sheet 4 is provided with anti-slip grooves 6. When disassembling the auxiliary rod 2, the worker manually moves the elastic cover sheet 4 to deform and rotate it to a certain angle, thereby making the elastic cover sheet 4 staggered with the installation slot 102, thereby facilitating the disassembly and assembly of the auxiliary rod 2.

[0042] This application is particularly suitable for places where children are present. Workers adjust the distance between two adjacent auxiliary rods 2 and the main rod 1 and the auxiliary rod 2 to no more than 11 cm, so as to provide a strong protection function for children. In the actual installation process, the bottom ends of the main rod 1 and the auxiliary rod 2 will be connected to other components.

[0043] The implementation principle of the adjustable pole distance handrail of the embodiment of the present application is as follows: when disassembling and assembling the auxiliary pole 2, the worker manually moves the elastic cover sheet 4 to deform and rotate it to a certain angle, thereby causing the elastic cover sheet 4 to be offset from the installation slot 102. After that, the worker manually pinches the positioning ring 3, inserts most of the ring body of the positioning ring 3 into the main pole 1 through the installation slot 102, and then releases it. At this time, the positioning ring 3 automatically restores its deformation, so that the positioning ring 3 automatically adheres to the inner wall of the main pole 1. According to the actual application site requirements of the handrail, the worker takes a suitable number of auxiliary poles 2 and adjusts the distance between two adjacent auxiliary poles 2, and then the handrail can be installed as a whole in the required site.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
