Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a safety protection device for construction engineering. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities. During the construction process of a construction project, it is necessary to separate the construction area from the outside world through protective devices to prevent non-construction workers from breaking in during construction. During the construction process of the project, the safety of passing personnel and vehicles must be guaranteed to avoid unnecessary trouble and safety accidents. Most of the safety protection devices used in some construction projects now use protective fences for blocking and protection.

[0003] However, some existing protective fences are large in size, poor in flexibility and practicality, and cannot be stored. They take up a lot of space when not in use and are inconvenient to carry and transport. To this end, we propose a safety protection device for construction projects to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safety protection device for construction engineering, comprising two boxes, a rectangular block is fixedly connected to the top of one of the boxes on the left, a vertical plate is fixedly connected to the top of the other box, two cross bars are rotatably connected to the left side of the vertical plate, the left ends of the two cross bars are fixedly connected to trapezoidal blocks, the two cross bars are fixedly connected to T-shaped blocks on the sides close to each other, the outer sides of the T-shaped blocks are slidably connected to sliders, the two sliders are fixedly connected to a first round rod on the sides close to each other, the outer sides of the two first round rods are slidably sleeved with the same second round rod, a spring is fixedly connected between the second round rod and the corresponding slider, the spring is movably sleeved on the outer side of the corresponding first round rod, and the inner wall of the two boxes on the side away from each other is rotatably connected to an X-shaped fence.

[0006] Further preferably, a vertical block is fixedly connected to the top of the crossbar, and a convex groove is provided on the right side of the rectangular block.

[0007] Further preferably, the sides of the boxes that are away from each other are fixedly connected with a transverse plate, and the bottom of the second round rod is fixedly connected with a support rod.

[0010] Further preferably, the bottom of the box is rotatably connected to two rollers, and a handle is fixedly connected to one side of the two boxes away from each other.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the building is no longer needed to be protected, the two handles are pushed, and the box drives the X-shaped fence to move and rotate, so that the trapezoidal block is squeezed, and the trapezoidal block drives the corresponding T-shaped block to move through the cross bar, so that the sliding of the slider is squeezed against the spring, and when the trapezoidal block moves to the second half of the convex groove, the spring that loses the squeezing force resets the trapezoidal block and resets it, and when it needs to be used again, the two vertical blocks are pinched, and the vertical blocks drive the trapezoidal block to move through the cross bar, and the handles are pulled to drive the X-shaped fence to move, and when it is unfolded to a suitable length, the screw is tightened to fix the box, so that the protective device is small in size during use, has high flexibility and practicality, can be stored, occupies a small amount of space when not in use, and is easy to carry and transport.
