Technical Field

[0001] The utility model belongs to the technical field of safety fences, in particular to an assembly and connection structure of a construction safety fence. Background Art

[0002] During the construction of a building, in order to prevent pedestrians from entering the construction site without protection, it is necessary to install a safety fence around the construction site. Since the length of the fence required to be laid is long, multiple safety fences need to be connected to each other. At this time, a splicing connection structure is required to stably connect adjacent safety fences.

[0003] In the Chinese utility model patent with publication number CN220599451U, a quick-disassembly protective net is disclosed, which can realize the convenient installation of the protective net body on one side of the fixed column. Similarly, it is also convenient for the quick disassembly of the protective net body and the fixed column, which is convenient for assembly;

[0004] However, after searching and studying, it is found that the protective net proposed in the above patent document still has some defects and shortcomings in actual installation and application: in the process of laying safety fences in reality, there are still connections at corners, but the protective net connection structure proposed in the above technical solution can only be connected and installed along a straight line, which is not convenient for firmly connecting adjacent safety fences at corners. The connection strength of the protective net at the corner is weak, which is difficult to meet the actual assembly and installation requirements of the safety fence. Therefore, it is urgent to improve the existing safety fence assembly connection structure and provide an assembly connection structure for construction safety fences. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and to provide an assembly connection structure for construction safety fences that has a reasonable design, a simple structure, and is convenient for firmly connecting adjacent fences at corners, so as to solve the problems in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A modular connection structure for a construction safety fence, comprising a fence main body, a docking assembly fixedly connected to the right end of the fence main body, a second column fixedly connected to the left end of the fence main body, a socket opened inside the bottom end of the second column, a top cover installed on the top end of the second column, a vertical groove opened on the left side wall of the top of the second column, a horizontal groove opened on the top front side wall of the second column, the horizontal groove is located at the top position of the vertical groove, and a locking assembly is installed inside the top end of the second column.

[0008] As a preferred embodiment, the docking assembly includes a first column, an insertion shaft and a square groove. The first column is fixedly connected to the right end of the fence body, the insertion shaft is fixedly connected to the bottom of the right end of the first column, and a square groove is opened at the top of the right end of the first column.

[0009] As a preferred embodiment, the plug shaft and the plug socket are adapted to each other.

[0010] As a preferred implementation, the top cover and the second column form a disassembly structure through bolts, and the vertical groove and the horizontal groove are connected to each other.

[0011] As a preferred embodiment, the locking assembly includes a threaded rod, a movable block, a fixed column, a sleeve, a spiral bevel and a positioning rod. The threaded rod bearing is connected to the top of the second column. The outer thread of the threaded rod is sleeved with the movable block. The front end outer wall of the movable block is welded and fixed with the fixed column. The outer movable sleeve of the movable block is provided with a sleeve. The bottom outer wall of the sleeve is provided with a spiral bevel. The top outer wall of the sleeve is fixedly connected with the positioning rod. A limit rod is provided on the right side of the threaded rod. The top of the limit rod is welded and fixed to the second column, and the limit rod is slidably connected to the movable block.

[0012] As a preferred embodiment, the sleeve is slidably located inside the top end of the second column, the end of the fixed column away from the movable block is guided and slidably located inside the spiral bevel, and the positioning rod is an inverted "L" shaped structure.

[0013] As a preferred embodiment, the bottom of the vertical section of the positioning rod is plugged and connected to the first column through a square groove, and the cross-sections of the vertical section of the positioning rod and the square groove are both square structures. Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the solution of the utility model:

[0015] By inserting the plug shaft into the socket opened inside the bottom end of the second column from top to bottom, the initial docking of two adjacent safety fences can be achieved. Then, the threaded rod is manually rotated to control the movable block to drive the fixed column to move down synchronously along the limit rod. At this time, the fixed column can squeeze the spiral bevel, so that the sleeve drives the positioning rod to rotate 90 degrees from the horizontal groove to the vertical groove. Then, when the threaded rod continues to rotate, the movable block can be controlled to drive the sleeve and the positioning rod to move down steadily along the vertical groove synchronously, so that the bottom of the vertical section of the positioning rod is inserted into the square groove opened at the top of the right end of the first column, and the stable assembly of two adjacent safety fences can be completed. The installation is quick and the operation is convenient.

[0016] Before controlling the positioning rod to move down and insert into the square groove, the two adjacent safety fences can be controlled to rotate around the insertion axis according to actual installation requirements, so that the two adjacent safety fences can be placed on the same straight line or arranged perpendicular to each other. Then, the positioning rod can be controlled to be inserted into the square groove to lock the states of the two safety fences, thereby facilitating a stable locking connection between adjacent fences at the corners. Compared with the solution in the patent literature that can only be connected in a straight line direction, the assembled connection structure proposed by the present device is more in line with actual usage and has greater practicality.

[0028] like Figure 1-7 As shown, the assembly and connection structure of the construction safety fence of the utility model includes a fence body 1, the right end of the fence body 1 is fixedly connected with a docking assembly 2, the left end of the fence body 1 is fixedly connected with a second column 3, the bottom end of the second column 3 is provided with a socket 4, the top end of the second column 3 is installed with a top cover 5, the top left side wall of the second column 3 is provided with a vertical groove 7, the top front side wall of the second column 3 is provided with a horizontal groove 8, the horizontal groove 8 is located at the top position of the vertical groove 7, and the top end of the second column 3 is installed with a locking assembly 9.

[0029] Based on the above structure, the docking assembly 2 includes a first column 21, an insertion shaft 22 and a square groove 23. The first column 21 is fixedly connected to the right end of the fence body 1. The insertion shaft 22 is fixedly connected to the bottom of the right end of the first column 21, and a square groove 23 is opened at the top of the right end of the first column 21.

[0030] In this embodiment, the arrangement of the insertion shaft 22 and the square groove 23 facilitates the butt connection between the first column 21 and the second column 3 between two adjacent safety fences.

[0031] On the basis of the above structure, the insertion shaft 22 and the insertion hole 4 are adapted to each other.

[0032] In this embodiment, by inserting the insertion shaft 22 into the inner side of the insertion hole 4, the connection and rotation adjustment of two adjacent safety fences are facilitated.

[0033] On the basis of the above structure, the top cover 5 and the second column 3 form a disassembly structure through bolts 6, and the vertical groove 7 and the horizontal groove 8 are connected to each other.

[0034] In this embodiment, the top cover 5 is provided to facilitate shielding and hiding of the locking assembly 9, thereby preventing pedestrians from arbitrarily operating the locking assembly and causing unstable connection of the safety fence.

[0035] On the basis of the above structure, the locking assembly 9 includes a threaded rod 91, a movable block 92, a fixed column 93, a sleeve 94, a spiral bevel 95 and a positioning rod 96. The threaded rod 91 is bearing-connected to the top inner part of the second column 3, the outer thread of the threaded rod 91 is sleeved with the movable block 92, the front end outer wall of the movable block 92 is welded and fixed with the fixed column 93, the outer movable sleeve of the movable block 92 is provided with a sleeve 94, the bottom outer wall of the sleeve 94 is provided with a spiral bevel 95, the top outer wall of the sleeve 94 is fixedly connected with the positioning rod 96, and a limit rod 97 is provided on the right side of the threaded rod 91, the top of the limit rod 97 is welded and fixed to the second column 3, and the limit rod 97 is slidably connected to the movable block 92.

[0036] Based on the above structure, the sleeve 94 slides inside the top of the second column 3, the end of the fixed column 93 away from the movable block 92 is guided and slid inside the spiral inclined groove 95, and the positioning rod 96 is an inverted "L" shape structure.

[0037] In this embodiment, the movable block 92 is controlled by the threaded rod 91 to move steadily downward along the limit rod 97. At this time, the spiral inclined groove 95 can be squeezed by the fixed column 93, so that the sleeve 94 drives the positioning rod 96 to rotate from the horizontal groove 8 to the vertical groove 7. Then, the movable block 92 can be controlled to drive the sleeve 94 and the positioning rod 96 to move steadily downward along the vertical groove 7 synchronously, and the bottom of the vertical section of the positioning rod 96 is inserted into the square groove 23, so as to complete the stable connection between the two adjacent safety fences.

[0038] On the basis of the above structure, the bottom of the vertical section of the positioning rod 96 is plugged and connected to the first column 21 through the square groove 23, and the cross-sections of the vertical section of the positioning rod 96 and the square groove 23 are both square structures.

[0039] In this embodiment, since the vertical section of the positioning rod 96 and the square groove 23 are both square structures in cross-section, two adjacent safety fences that are in the same straight line or in a perpendicular state can be locked and docked, facilitating the stable connection between adjacent fences at the corners.

[0040] The working principle of the utility model is as follows:

[0041] When in use, first insert the plug shaft 22 fixedly connected to the right end bottom of the first upright post 21 on the right side of a safety fence into the socket 4 opened at the bottom of the second upright post 3 on the left side of the other safety fence, to complete the preliminary docking of the two adjacent safety fences, then manually rotate the threaded rod 91 to control the movable block 92 to drive the fixed column 93 to move steadily downward along the limit rod 97, at this time, the positioning rod 96 is located in the restricted position in the horizontal groove 8 and cannot move downward with it, so the downward moving fixed column 93 can squeeze the spiral inclined groove 95, and make the sleeve 94 drive the positioning rod 96 to rotate 90°, so that the positioning rod 96 rotates from the horizontal groove 8 to the vertical groove 7, and then continue to control the threaded rod 91 to rotate, so that the movable block 92 can drive the fixed column 93, the sleeve 94 and the positioning rod 96 to move steadily downward along the vertical groove 7 synchronously, so that the bottom of the vertical section of the positioning rod 96 is inserted into the square groove 23 opened at the top of the right end of the first upright post 21, and the stable assembly of the two adjacent safety fences can be completed, which is quick to install and easy to operate;

[0042] Before assembling adjacent safety fences, the two adjacent safety fences can be controlled to rotate around the insertion shaft 22 according to actual installation requirements, so that the two adjacent safety fences are on the same straight line or are arranged perpendicular to each other, and then the bottom of the vertical section of the positioning rod 96 is controlled to be inserted into the square groove 23 to lock the two safety fences. Compared with the solution in the patent document that can only connect the safety fences in a straight line, the present device also facilitates the stable locking connection between the adjacent fences at the corners. The assembly connection structure proposed by the present device is more in line with the actual use and more practical.

[0043] After the safety fence is assembled, the top cover 5 can be fixedly installed on the top of the second column 3 by bolts 6, so as to isolate and protect the top of the threaded rod 91 and prevent random operation by strangers from affecting the connection stability of the safety fence.

[0044] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
