Description

Technical Field

[0001] The utility model relates to a handrail structure for supporting. Background Art

[0002] Handrails are widely used in various public places, especially for people with limited mobility. Handrails are generally installed on steel structures or walls. If they are installed on walls, expansion anchors must be buried first, and then the ends of the handrails are welded to the expansion anchors or steel structures. After welding, a decorative cover is usually spot welded to the weld to improve the aesthetics. However, since the welded ends of the handrails are relatively thin and have low supporting capacity, thicker plates must be used to meet the needs, resulting in high costs. Utility Model Content

[0003] The utility model aims to provide an armrest base structure with a more stable structure and a higher supporting capacity, thereby improving the safety of use.

[0004] The handrail base structure described in the utility model includes a handrail rod and a decorative cover sleeved on the end of the handrail rod, and also has a fixedly installed base and a gasket made of non-metallic material. The base is an annular metal sheet and is arranged on the inner side of the decorative cover. The side of the base facing the wall is provided with an inwardly concave positioning groove, the middle part of the positioning groove is annular and has a plurality of grooves extending radially outward, the gasket is arranged in the positioning groove and has an extension portion extending along each groove, and the base is also provided with a mounting hole for bolts to pass through and fix, and two or more mounting holes are evenly arranged along the ring of the base.

[0005] Furthermore, the positioning groove is recessed from one side of the base to protrude from the other side, and the positioning groove has two or more grooves extending radially outward.

[0006] Furthermore, there are four grooves and they are distributed in a cross-shaped structure.

[0007] Furthermore, the base between adjacent grooves is provided with the aforementioned mounting holes.

[0008] Furthermore, a bottom pad is provided on the side of the gasket facing the wall, and a mounting hole corresponding to the base is opened on the bottom pad.

[0009] Furthermore, the base pad and the gasket are integrally formed.

[0010] Furthermore, a ring with an annular protrusion is provided in the middle of the base, a positioning groove is provided on the outer side of the ring, and the ends of the handrail rod pass through the ring and are welded and fixed to each other.

[0011] The handrail base structure described in the utility model first drills the holes required for installation on the wall and installs the expansion anchor bolts, then puts the gasket into the positioning groove of the base, and passes the installation hole of the base through the expansion anchor bolt and locks it with a nut, so that the inner side of the gasket is pressed against the wall surface; then, insert the end of the handrail rod with the decorative cover into the annular through hole of the base, and finally cover the decorative cover after the handrail rod and the base are welded and fixed; similarly, the handrail rod and the base can be welded and fixed to each other first, and then the gasket is inserted and installed on the wall; and when the handrail needs to be removed, the nut can be directly removed. This handrail base structure arranges the base and the gasket in the original internal space of the decorative cover, which can better utilize the space and will not increase the volume of the handrail; when people use the handrail, most of the force will be transmitted to the wall through the base and the gasket, thereby reducing the force on the welding point of the handrail, greatly improving its supporting capacity and structural strength, and the arrangement of the gasket can not only prevent the base from sliding, but also transmit the force more effectively and evenly.

[0021] Embodiment 1, as Figure 1-3 shown.

[0022] The handrail base structure of the present embodiment includes a handrail rod 1 and a decorative cover 2 sleeved on the end of the handrail rod, and also has a fixedly installed base 3 and a gasket 4 made of non-metallic material. The base is an annular metal sheet and is arranged on the inner side of the decorative cover. An inwardly concave positioning groove 5 is provided on the side of the base facing the wall. The middle part of the positioning groove is annular and has a plurality of grooves extending radially outward. The gasket is arranged in the positioning groove and an extension portion 6 is extended along each groove. The base is also provided with a mounting hole 7 for bolts to pass through and fix, and two or more mounting holes are evenly arranged along the ring of the base.

[0023] like Figure 1-3 As shown, both ends of the handrail rod are installed with decorative covers, bases and gaskets; when installing the handrail, first drill the holes required for installation on the wall and install expansion anchors, then put the gasket into the positioning groove of the base, and pass the installation hole of the base through the expansion anchor and lock it with a nut to make the inner side of the gasket press against the wall; then, insert the end of the handrail rod with the decorative cover into the annular through hole of the base, and finally weld the handrail rod and the base and cover it with the decorative cover; similarly, the handrail rod and the base can be welded and fixed to each other first, and then the gasket is placed and installed on the wall; when the handrail needs to be disassembled, the nut can be directly removed.

[0024] In the armrest base structure, the positioning groove 5 is recessed from one side of the base 3 to the other side and protrudes, and the positioning groove extends radially outward with two or more grooves. Figure 3The four grooves shown form a cross-shaped structure, and the base between adjacent grooves is provided with the above-mentioned mounting holes 7, which can not only improve the structural strength of the base, thereby further improving the supporting capacity, but also make the end of the expansion anchor bolt and the nut hidden between the raised parts on the other side of the groove, so as to make fuller use of the internal space of the decorative cover, reduce the thickness of the decorative cover, and improve the aesthetics of the handrail. In addition, a ring 8 with an annular protrusion is provided in the middle of the base 3, and the positioning groove 5 is provided on the outside of the ring. The end of the handrail rod 1 passes through the ring and is welded and fixed to each other, so as to better place and position the gasket, improve the anti-slip performance and force transmission effect, and also increase the welding area between the base and the handrail rod, and improve the structural strength and supporting strength.

[0025] Embodiment 2, as Figure 4-6 shown.

[0026] In the armrest base structure of this embodiment, a base pad 9 is provided on the side of the gasket 4 facing the wall, and a mounting hole 7 corresponding to the base 3 is opened on the base pad; and the base pad 9 is integrally formed with the gasket 4; the rest is the same as the first embodiment.

[0027] The armrest base structure, through the provision of the base pad, can improve the anti-slip and sealing performance between the armrest and the wall, and form insulation between the armrest and the wall to avoid leakage and prevent static electricity from harming users. It can also fit more closely with the decorative cover, thereby facilitating the installation of the decorative cover and improving the aesthetics.

[0028] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
