Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and particularly to the field of edge opening protection technology, specifically referring to an edge opening protection fixing device. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] Edge openings typically refer to incompletely enclosed edges or openings on a construction site. These areas may be temporarily unsealed due to construction needs, but they pose a risk of falls and other accidents. Therefore, construction sites usually have safety measures in place, such as guardrails, safety nets, covers, or other protective facilities, to prevent people from falling or slipping through these openings or edges and causing injury.

[0004] For example, Chinese utility model patent (publication number CN217871940U) discloses a protective fixing device for edge openings, including a device body. The device body includes a first protective railing, a second protective railing, a stabilizing device, and a fixing device. The second protective railing is inserted and installed at the right end of the first protective railing. A set of stabilizing devices is installed at the bottom of the first and second protective railings respectively. The first protective railing includes a first vertical bar, a first guardrail post, and a second guardrail post. The first and second guardrail posts are installed in a row at equal intervals at the right end of the first vertical bar. The right ends and interiors of the first and second guardrail posts are hollow structures. The second protective railing includes a second vertical bar, a first connecting rod, and a second connecting rod. The first and second connecting rods are installed in a row at equal intervals at the left end of the second vertical bar. The surfaces of the first and second connecting rods have several sets of fixing holes distributed horizontally at equal intervals. This device can be used to enclose openings of different diameters, thus facilitating use by workers.

[0005] While the aforementioned technical solutions can effectively enclose openings of different diameters, the aforementioned edge-protection and fixing devices are placed on the outside of the opening for protection. If the device is lightweight, it is easily moved, resulting in poor protection. If the device is heavy, construction workers frequently pass through the opening due to commuting or construction needs, requiring frequent movement of the device, which is difficult, time-consuming, and laborious, thus causing inconvenience in use.

[0073] When it is necessary to disassemble the guardrail 1, hold the left handle 206 and apply force to the left, causing the left slider 203 to move to the left, compressing the left elastic element 205 and causing the left pin 204 to move to the left. Pull the right end of the left pin 204 out of the left slot 101 to the left. Hold the right handle 306 and apply force to the right, causing the right slider 303 to move to the right, compressing the right elastic element 305 and causing the right pin 304 to move to the right. Pull the left end of the right pin 304 out of the right slot 102 to the right. At this time, the guardrail 1 can be removed.

[0074] With the left limiting component 4 present, the left slider 203 moves to the left, also causing the first left stop 410 to move to the left. When the upper part of the first left stop 410 approaches the lower right side of the first left limiting block 408, by applying force to the first left handle 406 and the second left handle 407, the left sleeve 403 rotates horizontally counterclockwise (viewed from above). Through the left side wall of the left front groove 411 and the right side wall of the left rear groove 412, the front and rear ends of the left sliding rod 405 move upward, thereby causing the left moving rod 404 to move upward, which in turn causes the first left limiting block 408 to move upward and compress the left vertical elastic member 409. Thus, the lower part of the first left limiting block 408 will not block the upper left movement of the first left stop 410. The upper part of the left stop 410 can continue to move to the left, passing under the lower part of the first left limit block 408. After the upper part of the first left stop 410 has completely passed, the left sleeve 403 is reset by rotating the first left handle 406 and the second left handle 407 horizontally clockwise (viewed from above). Under the elastic force of the left vertical elastic member 409, the first left limit block 408 moves down, driving the front and rear ends of the left moving rod 404 and the left sliding rod 405 to move down and reset. After the first left limit block 408 moves down, it blocks the upper part of the first left stop 410 from moving to the right, thus limiting it. At this time, the first left stop 410 is in the first working position, and the right end of the left pin 204 is located on the left side of the left slot 101.

[0075] With the right limiting component 5 present, the right slider 303 moves to the right, also causing the first right stop block 510 to move to the right. When the upper part of the first right stop block 510 approaches the lower left side of the first right limiting block 508, by applying force to the first right handle 506 and the second right handle 507, the right sleeve 503 rotates horizontally clockwise (viewed from above). Through the right side wall of the right front groove 511 and the left side wall of the right rear groove 512, the front and rear ends of the right sliding rod 505 move upward, thereby causing the right moving rod 504 to move upward, which in turn causes the first right limiting block 508 to move upward and compress the right vertical elastic member 509. Thus, the lower part of the first right limiting block 508 will not block the upper part of the first right stop block 510 from moving to the right. The upper part of the right stop block 510 can continue to move to the right, passing under the lower part of the first right limit block 508. After the upper part of the first right stop block 510 has completely passed, the right sleeve 503 is reset by rotating the first right handle 506 and the second right handle 507 horizontally counterclockwise (viewed from above). Under the elastic force of the right vertical elastic member 509, the first right limit block 508 moves down, driving the front and rear ends of the right moving rod 504 and the right sliding rod 505 to move down and reset. After the first right limit block 508 moves down, it blocks the upper part of the first right stop block 510 from moving to the left, thus limiting it. At this time, the first right stop block 510 is in the second working position, and the left end of the right pin 304 is located on the right side of the right slot 102.

[0076] When the first left stop 410 is in the first working position and the first right stop 510 is in the second working position, the guardrail 1 can be easily removed and placed.

[0077] Therefore, compared with the prior art, the present invention has the following beneficial effects:

[0078] 1. This utility model, through the setting of guardrails, left fixing components and right fixing components, can effectively protect the openings near the edge, and at the same time realize the effect of convenient disassembly and assembly of guardrails, which greatly facilitates the movement of construction personnel.
