Embodiment 1

[0038] A wood-plastic guardrail, comprising a handrail 1 and a railing 2, the bottom of the handrail 1 is provided with an installation groove 3 adapted to the top of the railing 2 along the length direction of the handrail, the railing 2 is hollow to form an installation cavity, and the installation groove 3 A frame-shaped connector is provided, and the frame-shaped connector is a square connector. The frame-shaped connector includes a top mounting plate 4 and a frame wall plate 5, the mounting plate 4 is fixed on the mounting groove 3 by screws, and the frame-shaped connector is sheathed in the mounting cavity. A limiting groove 31 is arranged on the top surface of the installation groove 3 , and a limiting rib 41 adapted to the limiting groove 31 is arranged on the top of the installation plate 4 . The mounting plate 4 is fixed on the mounting groove 3 by two screws. Two screws further prevent the frame connector from turning. Clamping ribs 51 are provided on the outer su...

Embodiment 2

[0041] The difference from the above embodiment is that the limiting groove 31 is a single groove set concentrically with the installation groove 3 , and the top surface of the installation groove 3 is evenly distributed along the limiting groove 31 with ruled lines 32 .

Embodiment 3

[0043] The difference from the above embodiment is that the top surface of the mounting groove 3 is evenly distributed along the limiting groove 31 with equalizing grooves 33 interlaced with the limiting grooves 31, and the top of the mounting plate 4 is provided with the equalizing grooves 33 Adapted equal ribs 42. The center of the mounting plate 4 is provided with mounting holes for passing screws.

[0044] Due to the intersecting arrangement of the limiting groove and the equalizing groove, it is ensured that the connecting piece will not rotate. During design, the depth of the equalizing groove can be greater than the depth of the limit groove, so that the positioning stability of the frame-shaped connector can be ensured under the premise of ensuring the strength of the handrail.

Abstract

The invention belongs to the field of guardrails, and particularly relates to a wood-plastic guardrail simple in structure and convenient to install. The guardrail comprises an armrest and a railing. The bottom of the armrest is provided with an installation groove matched with the top of the railing in the length direction of the armrest, the railing is hollow to form an installation cavity, a frame-shaped connection element is arranged on the installation groove and comprises an instillation plate on the top and a frame wall plate, the installation plate is fixed to the installation groove through screws, and the frame-shaped connection element is arranged in the installation cavity in a sleeved mode. The top face of the installation groove is provided with a limiting groove, the top of the installation plate is provided with a limiting rib matched with the limiting groove, and the installation plate is fixed to the installation groove through the two screws. The railing is connected with the armrest through the frame-shaped connection element. Due to the fact that the shape of the frame-shaped connection element is matched with the installation cavity, when the guardrail is installed, people only need to direct connect the installation cavity with the frame-shaped connection element in a sleeved mode to position the railing, and the railing is installed in order and can not rotate. The guardrail is simple in structure and convenient to machine and install, parts are concise, and the installed guardrail is stable and orderly.

Description

technical field [0001] The invention belongs to the field of guardrails, in particular to a wood-plastic guardrail with simple structure and convenient installation. Background technique [0002] The existing guardrails on the market are either simply manually positioned and spliced ​​and then directly fixed with screws. Due to too many human factors, the splicing of the guardrails is often not neat enough, some of the guardrails are twisted, or the guardrails are loose, or the existing guardrails with Railings with metal inner cores have a complex structure and high cost, and workers cannot accurately and evenly distribute the railings, and it is troublesome to adjust the distance between the railings. And there will be a phenomenon that the railings are dispatched. For example, the application publication number CN 103046467 A discloses a wood-plastic guardrail with a metal inner core, which includes a column and a fence made of wood-plastic. The fence is composed of uppe...
