Description

Technical Field

[0001] The utility model relates to the technical field of stair handrails, in particular to a stair guardrail. Background Art

[0002] Stair handrails are the support rods of stair railings. Stair handrails are classified by material into: stair polymer handrails, stair wrought iron handrails, stair stainless steel handrails, stair glass handrails, stair solid wood handrails, and stair copper handrails.

[0003] Building handrails are generally composed of inclined horizontal railings and vertical railings. After long-term use, the guardrails of the building will be damaged, and the missing railings will cause large gaps, which will be dangerous when pedestrians pass by. The existing wooden building handrails are generally connected by bolts or mortise and tenon structures. The integrity of the attached body is relatively strong, which makes the later installation of vertical railings of the same length more troublesome and inconvenient to maintain. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a stair guardrail that can easily replace a single vertical railing and facilitate maintenance.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] By adopting the above technical solution, the installation mechanism, the plug-in slot, the plug-in block, the sliding block, and the handrail cooperate to facilitate the connection between the bottom railing and the handrail. When the bottom railing is damaged, the bottom railing can be easily replaced separately.

[0008] In a preferred example, the utility model can be further configured as follows: telescopic rods are provided in the two springs, and the two telescopic rods are respectively fixedly connected between the two spring slots and the two connecting blocks.

[0009] By adopting the above technical solution, the telescopic rod can prevent the spring from being compressed or bending and deforming when it recovers elastically.

[0011] By adopting the above technical solution, the adjustment mechanism can drive the bottom railing and the sliding block to move, thereby adjusting the position of the bottom railing.

[0012] In a preferred example, the utility model can be further configured as follows: each group of the adjustment mechanism also includes a cross slot and a limit rod, the cross slot is opened on one side of the limit block, the limit rod is fixedly connected between the side walls of the adjustment slot, and the sliding rod is slidably connected to the circumferential side of the limit rod.

[0013] By adopting the above technical solution, the limit block is rotated through the cross groove, and the protruding teeth on the circumferential side of the limit block rotate with the limit block. The limit block abuts against the circumferential side of the adjustment groove, so the position of the bottom railing can be limited.

[0014] In a preferred example, the utility model can be further configured as follows: a plurality of the bottom railings are provided with connecting mechanisms, and a plurality of groups of connecting mechanisms are respectively connected to a plurality of connecting plates, each group of the connecting mechanisms includes a slot, a block and a plurality of limit screws, the slot is opened on one side of the bottom railing, the block is fixedly connected to the upper end of the connecting plate, the block is slidably connected to the limit screw, and a plurality of the limit screws are respectively threadedly connected to both sides of the bottom railing.

[0015] By adopting the above technical solution, the connecting mechanism can facilitate the connection between the bottom railing and the connecting plate.

[0016] In a preferred example, the utility model can be further configured as follows: a plurality of connecting screws are disposed above the plurality of connecting plates, and the plurality of connecting screws are threadedly passed through the lower ends of the plurality of connecting plates respectively.

The insert block is inserted into the plug-in slot. The connecting block is squeezed by the inner wall of the plug-in slot and shrinks into the spring slot. The spring is in a compressed state. When the connecting block reaches the connecting slot, the spring pushes the connecting block back to its original position due to its own elastic recovery, which facilitates the connection between the bottom railing and the handrail. When the bottom railing is damaged, the bottom railing can be easily replaced separately.

[0020] 2. A connecting mechanism, a bottom railing and a connecting plate are provided. When the bottom railing slides in the installation groove, the card block is inserted into the card slot, so that the bottom railing and the connecting plate are locked together. The limit screw is rotated into the bottom railing, and the hexagonal edge on the bottom railing can fit the card block. The limit screw restricts the two sides of the card block to prevent the card block from leaving the card slot, thereby fixing the bottom railing and the connecting plate.
