Description

Technical field

[0001] The utility model relates to the technical field of guardrails, in particular to a temporary guardrail that is easy to install. [Background Technology]

[0002] During the later decoration and renovation stage of building construction or the main steel structure construction stage, corresponding guardrails need to be installed on the edges of high floors to protect people from falling (for example, floor-to-ceiling windows and other locations are in a hollow state when there is no glass installed and no decorative railings).

[0003] Existing standardized edge guardrails (such as punched steel guardrails) are not adjustable in length and height. Installation typically requires drilling holes in the wall or ground foundation, which are then secured with bolts and other accessories. This makes them difficult to install and remove, and the holes often require repair. Therefore, a temporary guardrail that is easy to install is proposed to address these issues. [Utility Model Content]

[0004] The purpose of the utility model is to provide a temporary guardrail that is easy to install, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A temporary guardrail that is easy to install, comprising two upper and lower parallel telescopic cross bars and a telescopic railing disposed between the two telescopic cross bars; the telescopic cross bars comprise a plurality of first sleeves and a plurality of connecting rods, wherein the first sleeves are provided with movable cavities within which two limit sliders are slidably disposed; the connecting rod is located between two adjacent first sleeves, and the ends of the connecting rod respectively extend into corresponding first sleeves and are fixedly connected to the nearest limit slider;

[0007] The ends of the two ends of each telescopic cross bar are connecting rods, and the outer ends of the connecting rods at both ends of the telescopic cross bar are provided with U-shaped mounting heads opening outward, and the front side panels of the U-shaped mounting heads are provided with fixing bolts;

[0008] The first sleeves of the two telescopic cross bars are correspondingly arranged above and below, and the corresponding sides of the upper and lower first sleeves are respectively provided with facing rotating mounting heads, and both ends of each telescopic railing are rotatably mounted on the two corresponding rotating mounting heads above and below.

[0009] As a preferred solution, the fixing bolt passes through the front panel of the U-shaped mounting head from front to back and is threadedly connected thereto, and an extrusion plate is rotatably provided on the inner end of the fixing bolt.

[0010] As a preferred solution, anti-slip protrusions are provided on the inner wall of the U-shaped mounting head.

[0011] As a preferred solution, a rotatable mounting seat is fixedly provided at the middle position of the U-shaped mounting head facing the telescopic cross bar, and the connecting rod at the end of the telescopic cross bar is rotatably connected to the rotatable mounting seat of the corresponding U-shaped mounting head.

[0012] As a preferred solution, the first sleeve and the connecting rod have the same length.

[0013] As a preferred solution, the telescopic railing includes a vertical rod and a second sleeve, the lower end of the vertical rod and the upper end of the second sleeve are sleeved on each other, and the two are threadedly connected.

[0014] It can be seen from the technical solution provided by the above utility model that the utility model provides a temporary guardrail that is easy to install, and the beneficial effects are:

[0015] 1. Two telescopic crossbars arranged horizontally one above the other serve as the basic structure of the guardrail. The telescopic crossbars are formed by splicing together multiple first sleeves and multiple connecting rods, which can be extended and retracted to adjust the length of the guardrail. Rotating mounting heads are provided at both ends of the first sleeves for mounting the telescopic railings, which are used to adjust the height of the guardrail.

[0016] 2. U-shaped mounting heads are set at both ends of the telescopic crossbar, which can be fixed on the wall at the gap of the outer wall or on the steel structure beams and columns with fixing bolts, making installation and disassembly easy.

[0017] 3. The guardrail can be retracted and adjusted when not in use or disassembled, which is convenient for turnover.
