Description

Technical Field

[0001] This utility model relates to the field of handrail technology, specifically to a high-strength stair handrail. Background Technology

[0002] Handrails are commonly used on moving objects or in places where slip prevention is necessary. Many handrails in vehicles and homes are made of ordinary steel, which has poor corrosion resistance and low strength, frequently leading to handrail damage and injuries. Patent CN202122178329.5 discloses a high-strength stair handrail. Through a limiting slot, the end of the handrail is installed into the limiting slot, passing through a through-hole. The beveled opening is then rotated into the limiting slot. As it gradually extends into the limiting slot, the clamp gets closer and closer to the handrail. When fully extended into the limiting slot, the clamp is tightly pressed against the handrail, thus securing it. However, if a break occurs at the welded joint, although the handrail will not wobble, the exposed break can easily cause abrasions if someone accidentally touches it. Therefore, we propose a high-strength stair handrail. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a high-strength stair handrail.

[0004] The technical solution adopted by this utility model to solve its technical problem is a high-strength stair handrail, including diagonal bars and horizontal bars. An elbow is assembled between the diagonal bar and the horizontal bar, and the bottom surface of the elbow, the bottom surface of the diagonal bar, and the bottom surface of the horizontal bar are all equipped with support rods for support. There are multiple sets of support rods. The side of the elbow opposite to the diagonal bar and the side of the elbow opposite to the horizontal bar are equipped with a tapered seat and a tapered tube that are connected to each other. The tapered seat and the tapered tube are welded together. The outer periphery of the tapered tube and the tapered seat are integrally constructed with a ring body. A buckle seat is fastened between the two sets of ring bodies. The outer periphery of the buckle seat is integrally constructed with lugs for fastening. There are multiple sets of lugs. Fastening bolts for fixing are assembled between the two sets of lugs.

[0005] A rubber ring is snapped between the elbow and the diagonal bar and between the elbow and the crossbar, located on the outer periphery of the buckle seat. An aluminum shell layer is assembled on the outer periphery of the rubber ring. Plastic rings are bonded between the aluminum shell layer and the elbow, between the aluminum shell layer and the crossbar, and between the aluminum shell layer and the diagonal bar. Rivets for fastening are riveted to the outer periphery of the aluminum shell layer, and there are multiple sets of rivets.

[0006] By adopting the above technical solution, when installing the handrail, the tapered tubes at both ends of the elbow can be connected with the tapered seats at the outer ends of the crossbar and diagonal bar. After the connection is completed, welding is convenient, and the welding position is located between the two sets of rings on the outer side of the tapered tube and the tapered seat. Then, the buckle seat is taken out so that it can fit with the ring and be locked on the outer circumference of the tapered tube and the tapered seat. Then, the fastening bolts are connected to the two sets of lugs on the outer circumference of the buckle seat to facilitate the fastening of the buckle seat. The buckle seat can also wrap and protect the welding position, reducing the impact caused by the breakage of the welding position.

[0007] After the buckle seat is positioned correctly, rubber rings and aluminum shells of appropriate length can be cut to fit around the welded joint between the elbow and the diagonal bar or the elbow and the crossbar. The aluminum shell is then secured with rivets, and welding is performed at the opening after the aluminum shell is rolled up. Simultaneously, the plastic ring pre-fitted around the elbow and diagonal bar or crossbar can be moved and heat-sealed to fix it in place at the gap between the aluminum shell and the elbow or the crossbar or diagonal bar. After grinding the edges, the elbow installation is complete. This process also protects the buckle seat, creating an internal structure between the buckle seat and the welded area. This reduces the risk of corrosion and breakage at the welded joint and ensures more stable operation of the handrail.

[0008] Specifically, the outer peripheral surfaces of the elbow, the diagonal bar, and the crossbar are all integrally constructed with anti-slip teeth.

[0009] By adopting the above technical solution, the anti-slip teeth can improve the tightness of the plastic ring during heat sealing, so that the plastic ring can more firmly seal and protect the gap.

[0010] Specifically, a sponge pad located between the two sets of rings is bonded to the inner circumference of the buckle.

[0011] By adopting the above technical solution, the sponge pad has good elasticity, so that when the buckle seat is installed on the outer periphery of the two sets of rings, it will not affect the welding layer of the welding part between the tapered seat and the tapered tube.

[0012] Specifically, both the tapered seat and the outer circumferential surface of the tapered tube are provided with grooves that fit with the buckle seat, and a rubber pad is adhered in the groove.

[0013] By adopting the above technical solution, the groove and the buckle seat fit together, which facilitates the improvement of the stability of the buckle seat after installation.

[0014] Specifically, the outer circumferential surfaces of the elbow, the diagonal bar, and the crossbar are all provided with annular grooves that fit the rubber ring.

[0015] By adopting the above technical solution, the annular groove can easily fit into the rubber ring, which facilitates the improvement of the stability of the rubber ring after installation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of crossbars, diagonal bars, elbows, tapered seats, tapered tubes, rings, buckle seats, lugs, and fastening bolts, allows the tapered tubes at both ends of the elbows to connect with the tapered seats at the outer ends of the crossbars and diagonal bars during handrail installation. This connection facilitates welding, with the welding position located between the two sets of rings on the outer sides of the tapered tubes and tapered seats. The buckle seats, which are easy to open and close, fit snugly against the rings and are secured to the outer circumference of the tapered tubes and tapered seats. Fastening bolts are then used to connect the buckle seats to the two sets of lugs on the outer circumference of the buckle seats, facilitating fastening and protecting the welded area, thus reducing the impact of weld breakage.

[0018] 2. The technical solution of this application, through the design of rubber rings, aluminum shell layers, rivets, and plastic rings, allows for the cutting of rubber rings and aluminum shell layers of appropriate lengths after the buckle seat is installed. This enables the flexible rubber rings and aluminum shell layers to wrap around the welding points between the elbow and the diagonal bar or the elbow and the crossbar, facilitating a proper fit. The rivets then fix the aluminum shell layer in place, and welding is performed at the opening after the aluminum shell layer is rolled up. Simultaneously, the plastic rings pre-fitted around the elbow and diagonal bar or crossbar can be moved, and heat-sealed to fix the plastic rings in the gaps between the aluminum shell layer and the elbow or the crossbar or diagonal bar. After grinding the edges, the elbow installation is complete. This design also facilitates the protection of the buckle seat, creating an internal structure between the buckle seat and the welded area. This not only reduces the risk of corrosion and breakage at the welded area but also protects the welded area, resulting in more stable operation of the handrail. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a high-strength stair handrail, including a diagonal bar 3 and a horizontal bar 2. An elbow 4 is fitted between the diagonal bar 3 and the horizontal bar 2. Support rods 1 for support are fitted on the bottom surfaces of the elbow 4, the diagonal bar 3, and the horizontal bar 2. Multiple sets of support rods 1 are provided. Conical seats 5 and conical tubes 6 are fitted on the opposite sides of the elbow 4 and the opposite sides of the elbow 4 and the horizontal bar 2. The conical seats 5 and conical tubes 6 are welded together. A ring 7 is integrally formed on the outer periphery of both the conical tube 6 and the conical seat 5. The two sets of rings 7 are interlocked. There is a buckle seat 8, and the outer circumference of the buckle seat 8 is integrally constructed with lugs 9 for fastening, and there are multiple sets of lugs 9. Fastening bolts 10 for fixing are assembled between two sets of lugs 9. A rubber ring 11 located on the outer circumference of the buckle seat 8 is snapped between the elbow 4 and the diagonal bar 3 and between the elbow 4 and the cross bar 2. An aluminum shell layer 12 is assembled on the outer circumference of the rubber ring 11. A plastic ring 14 is bonded between the aluminum shell layer 12 and the elbow 4, between the aluminum shell layer 12 and the cross bar 2, and between the aluminum shell layer 12 and the diagonal bar 3. Rivets 19 for fastening are riveted to the outer circumference of the aluminum shell layer 12, and there are multiple sets of rivets 19.

[0027] When using the handrail, the tapered tubes 6 at both ends of the outer side of the elbow 4 can be connected with the tapered seats 5 at the outer side of the crossbar 2 and the diagonal bar 3. After the connection is completed, welding is convenient. The welding position is located between the two sets of rings 7 on the outer side of the tapered tube 6 and the tapered seat 5. Then, the buckle seat 8, which is easy to open and close, is taken so that the buckle seat 8 can fit with the ring 7 and be locked on the outer periphery of the tapered tube 6 and the tapered seat 5. Then, the fastening bolts 10 are connected to the two sets of lugs 9 on the outer periphery of the buckle seat 8 to facilitate the fastening of the buckle seat 8 and to protect the welded position, reducing the impact caused by the welded position breaking.

[0028] After the buckle seat 8 is installed in the correct position, rubber rings 11 and aluminum shell layers 12 of appropriate length can be cut so that the bendable rubber rings 11 and aluminum shell layers 12 can wrap around the welding position between the elbow 4 and the diagonal bar 3 or the elbow 4 and the crossbar 2, and fit easily in this position. Then, rivets 19 are used to fix the position of the aluminum shell layer 12 and weld it at the opening after the aluminum shell layer 12 is rolled up. At the same time, the plastic ring 14 pre-fitted around the elbow 4 and the diagonal bar 3 or the crossbar 2 can be moved and fixed to the gap between the aluminum shell layer 12 and the elbow 4 and the aluminum shell layer 12 and the crossbar 2 or the diagonal bar 3 by heat sealing. After grinding the edges, the installation of the elbow 4 is completed, which also facilitates the protection of the buckle seat 8. The buckle seat 8 and the welding part have an internal structure, which not only reduces the possibility of corrosion and breakage at the welding part, but also protects the welding part, making the handrail operate more stably.

[0029] like Figure 2 and Figure 3 As shown, the outer circumferential surfaces of the elbow 4, the diagonal bar 3, and the crossbar 2 are all integrally constructed with anti-slip teeth 17.

[0030] When in use, the anti-slip teeth 17 facilitate the tightening of the plastic ring 14 during heat sealing, enabling the plastic ring 14 to more securely seal and protect the gap.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, a sponge pad 16 located between the two sets of rings 7 is bonded to the inner circumference of the buckle.

[0032] When in use, the sponge pad 16 has good elasticity, so that when the buckle seat 8 is installed on the outer periphery of the two sets of rings 7, it will not affect the welding layer of the welding part between the tapered seat 5 and the tapered tube 6.

[0033] like Figure 2 and Figure 3 As shown, both the tapered seat 5 and the tapered tube 6 have grooves 15 on their outer circumferential surfaces that fit with the buckle seat 8, and a rubber pad 18 is glued inside the groove 15.

[0034] During use, the groove 15 and the buckle seat 8 fit together, which helps to improve the stability of the buckle seat 8 after installation.

[0035] like Figure 2 and Figure 3 As shown, the outer circumferential surfaces of the elbow 4, the diagonal bar 3, and the crossbar 2 are all provided with annular grooves 13 that fit with the rubber ring 11.

[0036] During use, the annular groove 13 can easily fit into the rubber ring 11, which helps to improve the stability of the rubber ring 11 after installation.

[0037] The working principle and usage process of this utility model are as follows: First, install the corresponding structural components in appropriate positions. When installing the handrail, the tapered tubes 6 at both ends of the outer side of the elbow 4 can be connected to the tapered seats 5 at the outer ends of the crossbar 2 and diagonal bar 3. This connection facilitates welding, and the welding position is located between the two sets of rings 7 on the outer side of the tapered tube 6 and the tapered seat 5. Then, take the easily openable buckle seat 8, allowing it to fit snugly against the rings 7 and be secured to the outer circumference of the tapered tube 6 and the tapered seat 5. Then, use the fastening bolts 10 to connect with the two sets of lugs 9 on the outer circumference of the buckle seat 8, facilitating the tightening of the buckle seat 8 and ensuring that the buckle seat 8 can protect the welded area, reducing the impact of weld breakage. After installing the buckle seat 8, a rubber ring 11 of appropriate length can be cut. The aluminum shell layer 12 allows the bendable rubber ring 11 and aluminum shell layer 12 to wrap around the welding position between the elbow 4 and the diagonal bar 3 or the elbow 4 and the crossbar 2, and to easily fit in this position. Then, the position of the aluminum shell layer 12 is fixed by rivets 19, and welding is performed at the opening after the aluminum shell layer 12 is rolled up. At the same time, the plastic ring 14 pre-fitted on the outer periphery of the elbow 4 and the diagonal bar 3 or the crossbar 2 can be moved. The plastic ring 14 is fixed in the gap between the aluminum shell layer 12 and the elbow 4 and the aluminum shell layer 12 and the crossbar 2 or the diagonal bar 3 by heat sealing. After grinding the edges, the installation of the elbow 4 is completed, and it is convenient to protect the buckle seat 8. The buckle seat 8 and the welding part have an internal structure, which not only reduces the possibility of corrosion and breakage at the welding part, but also protects the welding part, so that the handrail can operate more stably.
