Technical Field

[0001] This utility model belongs to the field of building foundation pit safety protection technology, specifically a building foundation pit safety protection device. Background Technology

[0002] Construction engineering refers to a series of technical activities, including planning, design, construction, and management, for the purpose of building or constructing structures. It involves knowledge and technology from multiple disciplines, including but not limited to structural engineering, civil engineering, architecture, electrical engineering, mechanical engineering, and project management. Construction engineering generally requires the excavation of foundation pits during foundation construction, and safety railings are usually installed next to the foundation pits for safety protection.

[0003] Chinese utility model patent CN208024077U discloses a foundation pit guardrail for construction, including posts, horizontal bars, vertical bars, a base, a fixing rod, and a support rod. Two horizontal bars are horizontally parallel at both ends between two posts, with both ends hinged to the posts. One end of the fixing rod is riveted to the horizontal bar, and the other end is riveted to the post. The lower end of the post is inserted and fixed to the base, and the support rod is riveted to the post. A battery and a control board are fixedly installed inside the post, and a warning light and a buzzer are fixedly installed at the top of the post. The warning light design of this utility model can more clearly alert passersby to safety at night, and the buzzer design can further remind those who deliberately ignore safety warnings. The solar charging panel design allows the guardrail to operate normally without an external power source.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the pit guardrail is inconvenient to adjust its length during use and is not easy to reduce storage space when idle.

[0005] Therefore, those skilled in the art have proposed safety protection devices for building foundation pits to address the problems raised in the background art. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a safety protection device for building foundation pits, which solves the problems of existing foundation pit guardrails being inconvenient to adjust in length during use and difficult to reduce storage space when not in use.

[0007] The safety protection device for building foundation pit includes a first hollow column, a first connecting rod disposed at one end of the first hollow column, a second hollow column disposed below the first hollow column, and a second connecting rod disposed below the first connecting rod. The lower surface of the first hollow column is provided with a limiting component for limiting it on the second hollow column, and one end of the first hollow column is provided with an installation component for installing it on the first connecting rod.

[0008] The limiting component includes a plurality of uniformly distributed cylinders fixedly connected to the lower surface of the first hollow column and a cylindrical tube slidably connected to the surface of the cylinders, with the lower ends of the plurality of cylinders fixedly connected to the upper surface of the second hollow column.

[0009] Preferably, a plurality of uniformly distributed cylinders are fixedly connected to the lower surface of the first connecting rod, and a cylinder is slidably connected to the surface of the cylinder, the lower end of the cylinder being fixedly connected to the upper surface of the second connecting rod.

At this time, the insertion rod is located in the insertion hole at the top inside the cylinder, effectively reducing the space occupied when not in use. When unfolding, simply slide the cylinder inside the cylinder, and the insertion rod is located in the insertion hole at the bottom inside the cylinder, thus unfolding the device for use. Compared with existing foundation pit guardrails, this device can effectively reduce the space occupied when not in use, achieving the effect of facilitating unfolding, use, and storage.

[0013] Preferably, the mounting assembly includes solid rods slidably connected within the first hollow column and the second hollow column. One end of each of the two solid rods is fixedly connected to one end of the first connecting rod and the second connecting rod, respectively. A plurality of evenly distributed through grooves are provided in the solid rod located within the first hollow column. Limiting rods are slidably connected within the through grooves. The lower end of each limiting rod is slidably connected within the solid rod located within the second hollow column, and a plurality of limiting rods are provided.

[0014] Preferably, a limiting groove is formed in the inner top wall of the first hollow column, and a limiting block is slidably connected in the limiting groove. The lower end of the limiting block is fixedly connected to the upper surface of the solid rod.

[0015] Preferably, the lower surfaces of the second hollow column and the second connecting rod are provided with mounting grooves, and two symmetrically arranged mounting blocks are rotatably connected in the mounting grooves. The mounting blocks are provided with mounting holes.

[0016] Preferably, a connecting block is fixedly connected to one end of both the first hollow column and the first connecting rod, and the connecting block has a plurality of symmetrically arranged threaded holes.

[0017] With the above technical solution, when in use, the mounting block is rotated to fit the mounting block to the ground, and then the device can be installed on the ground with bolts through the mounting holes. Two devices can be used together by bolting through the threaded holes on the connecting block. The length of the device can be adjusted by sliding the solid rod in the first hollow column, and the two solid rods can be used as a guardrail by inserting the limiting rod into the through groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model allows the height of the first hollow column to be lowered by sliding the cylinder inside the cylinder, thereby reducing the height of the device and making it easier to store. At this time, the insertion rod is located in the insertion hole at the top inside the cylinder, effectively reducing the space occupied when not in use. When unfolding, simply slide the cylinder inside the cylinder, and the insertion rod is located in the insertion hole at the bottom inside the cylinder, thus unfolding the device for use. Compared with existing foundation pit guardrails, this device can effectively reduce the space occupied when not in use, and achieves the effect of convenient unfolding and storage.

[0020] 2. This utility model uses a rotating mounting block to fit the mounting block to the ground. Then, the device can be installed on the ground with bolts through the mounting holes.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown: This utility model provides a safety protection device for building foundation pits, including a first hollow column 1, a first connecting rod 3 disposed at one end of the first hollow column 1, a second hollow column 2 disposed below the first hollow column 1, and a second connecting rod 4 disposed below the first connecting rod 3.

[0037] A connecting block 106 is fixedly connected to one end of the first hollow column 1 and the first connecting rod 3. Several symmetrically arranged threaded holes 107 are opened in the connecting block 106.

[0038] As can be seen from the above, when in use, the mounting block 202 is rotated to fit the mounting block 202 to the ground. Then, the device can be installed on the ground with bolts through the mounting hole 203. Two devices can be used together by bolts through the threaded hole 107 on the connecting block 106.
