Description

Technical Field

[0001] This utility model relates to the field of building auxiliary facilities technology, specifically a folding edge protection railing. Background Technology

[0002] Chinese patent document CN209799443U discloses an edge protection railing, which proposes a horizontal bar between adjacent posts. Two fixing plates are located at the ends of the horizontal bar, with their semi-circular recesses facing each other. One end of the two fixing plates is connected together, while the other end leaves a space for the posts to move in. The horizontal bar connects to the two fixing plates at a position away from the space. Springs are arranged opposite each other within the two fixing plates. Parallel connecting plates are respectively provided at the ends of the two fixing plates away from the horizontal bar. The edges of the connecting plates away from the fixing plates have grooves facing inwards. Connecting components for moving the two connecting plates relative to each other are provided within the grooves. The connecting components include a first spring, with abutment plates at both ends that abut against the surfaces of the connecting plates opposite to each other. The fixing plates can resist the elastic force of the first spring to move relative to each other, thereby clamping the posts and fixing the horizontal bar. The fixing method is convenient and simple.

[0003] When the above-mentioned solutions and existing technologies are used for edge protection railings, the standard length of the conventional railing is usually 2m. When protecting the edge of foundation pits or large-span buildings, the length of a single conventional railing panel is often too small, requiring multiple handling, positioning and installation, which generates a lot of manpower. In addition, traditional fences are single panels connected by posts in the middle, which requires installation and disassembly, making them very troublesome and unable to meet the actual needs of use.

[0004] Therefore, this utility model proposes a foldable edge protection railing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a foldable edge protection railing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding edge protection railing, comprising a support base, a pivot, and a folding auxiliary component;

[0007] The upper end face of the support base is provided with a rotating shaft, and a limiting sleeve is fitted on the rotating shaft;

[0008] A movable sleeve is provided above the limiting sleeve, and the movable sleeve is movably connected to the rotating shaft. The movable sleeve is also connected to the grid, and the grid is fixedly provided with fences at equal intervals. The folding auxiliary component is provided on the rotating shaft.

[0009] Preferably, the folding auxiliary component includes a fixing rod and an external thread; a limiting sleeve is provided above the movable sleeve, and the limiting sleeve is movably connected to the rotating shaft, and a fixing rod is provided at the end of the rotating shaft, and the upper and lower outer walls of the fixing rod are both provided with external threads.

[0010] Preferably, a limiting ring is provided on the fixing rod via an external thread connection, and the limiting ring is provided with positioning grooves at equal intervals.

[0011] Preferably, a first reinforcing plate is provided above the limiting ring, and a second reinforcing plate is provided above the first reinforcing plate. Both the first and second reinforcing plates are fixedly provided with fixing holes, and the first and second reinforcing plates are movably inserted into the fixing rod through the provided fixing holes.

[0012] Preferably, positioning holes are provided at equal intervals on both the first reinforcing plate and the second reinforcing plate.

[0013] Preferably, a positioning ring is provided above the second reinforcing plate, and a fixing hole is fixedly provided on the positioning ring, and a positioning rod is provided below the positioning ring.

[0014] Preferably, the positioning ring is movably inserted into the fixed rod, and the positioning rod located below the positioning ring passes through the first reinforcing plate and the second reinforcing plate and connects to the positioning groove on the limiting ring.

[0015] Preferably, the positioning ring is fixedly connected to the first reinforcing plate and the second reinforcing plate by a fixing nut.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting folding auxiliary components on the support base of the connecting end of the edge protection railing, the railings are hinged together. The flip-up connection structure allows for long-length folding or extension transfer, which can be carried out by crane. The top of each grid is designed with a limit to ensure that several adjacent grids are in a straight line. The first and second reinforcing plates at the top of each grid are thickened to prevent excessive stress during transfer, which could cause deformation and shorten the service life, thus meeting the actual use requirements.
