Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to a protective fence for construction engineering. Background Technology

[0002] Protective fences are a common warning device. In the construction industry, protective fences are often used to warn unauthorized personnel not to enter the construction area. There are many types of protective fences, including modular protective fences, which are generally composed of two parts: posts and railings. They are widely used due to their ease of handling.

[0003] Existing modular protective fences are installed with the fences and posts running parallel to each other, with no obvious connection between adjacent fences and the connection points between the fences and posts being directly exposed. As a result, a single fence can be unlocked and removed from the middle, making the overall anti-theft device ineffective. Therefore, a new type of protective fence for construction projects is proposed to solve the above problems. Utility Model Content

[0011] The locking assembly includes a spring piece, the front end of which is fixedly connected to the inner wall of the fixing plate, and a triangular block is fixedly connected to the top end of the spring piece. The inner wall of the positioning sleeve is provided with a locking groove, and the triangular block and the locking groove are adapted to each other.

[0012] As a further description of the above technical solution:

[0013] The triangular block is set as a right triangle with the inclined plane facing backward.

[0014] As a further description of the above technical solution:

[0015] Multiple sets of positioning plates and positioning sleeves are provided, and the multiple sets of positioning plates and positioning sleeves are symmetrically arranged with the center line of the baffle as the axis of symmetry.

[0016] As a further description of the above technical solution:

[0031] Reference Figure 2 - Figure 4The outer wall of the fixing rod 6 is fitted with a positioning sleeve 3 to seal the top opening of the fixing hole 13. The top of the positioning sleeve 3 is fixedly connected to a baffle 4 to block the top opening of the slot 12. The left end of the fixing plate 7 is provided with a positioning plate 9 for fixing the positioning sleeve 3. The positioning plate 9 is L-shaped, and the positioning sleeve 3 is L-shaped. The left end of the L-shaped positioning sleeve 3 can be inserted into the interior of the positioning plate 9 by plugging, thus fixing the positioning sleeve 3 and preventing it from moving up and down. The inner wall of the fixing plate 7 is provided with a locking component 8 for fixing the positioning sleeve 3. The locking component 8 includes a spring piece 81 for moving the triangular block 82. The front end of the spring piece 81 is fixed. The spring piece 81 is made of plastic and has elastic deformation capability. The top of the spring piece 81 is fixedly connected to the inner wall of the fixed plate 7. The positioning sleeve 3 is provided with a locking groove 83 to accommodate the triangular block 82. The triangular block 82 and the locking groove 83 are compatible. When the triangular block 82 is inserted into the locking groove 83, the front face of the triangular block 82 will contact the front face of the inner wall of the locking groove 83. In this way, the positioning sleeve 3 will be restricted from moving backward. The triangular block 82 is set as a right triangle with the inclined surface facing backward. When the inclined surface of the triangular block 82 is squeezed, the triangular block 82 will be forced to move downward.

[0032] Reference Figure 2 - Figure 4 Multiple sets of positioning plates 9 and positioning sleeves 3 are provided. The multiple sets of positioning plates 9 and positioning sleeves 3 are symmetrically arranged with the center line of the baffle 4 as the axis of symmetry. The two sets of positioning sleeves 3 will respectively close the two sets of fixing holes 13. The bottom end of the left buckle 5 is flush with the top end of the right buckle 2, and the top end of the left buckle 5 is flush with the top end of the fixing rod 6. The two sets of adjacent protective frames 1 can be connected to the inside of the slot 12 at the same time through the left buckle 5 and the right buckle 2. When disassembly is required, the protective frame 1 on the right side of the fixing rod 6 must be removed first, and then the other set of protective frames 1 on the left side can be removed. The outer wall of the upright 14 is fitted with a plastic buckle 11 for fixing the sign 10. The front end of the plastic buckle 11 is fixedly connected to the sign 10 for warning pedestrians.

[0033] Working principle: When installing the entire device, first fix the fixing rod 6 and fixing plate 7 to the installation point through the fixing hole 13. Then, insert the right buckle 2 at the right end of one set of protective frames 1 into the slot 12. Then insert the left buckle 5 at the left end of another set of protective frames 1 into the slot 12. This completes the installation of the two sets of protective frames 1. When inserting the right protective frame 1, make sure to insert the right buckle 2 on the right side of the protective frame 1 into the slot 12 at the front end of the other set of fixing rods 6 at the same time. The installation can be completed by doing this in sequence. When disassembling, the direction needs to be adjusted and disassembled from right to left.

[0034] After installation, the positioning sleeve 3 can be inserted into the top of the fixing plate 7. The positioning sleeve 3 can seal the top of the fixing hole 13, thus preventing the bolt inside the fixing hole 13 from moving upward and loosening. At the same time, during the insertion of the positioning sleeve 3, the positioning sleeve 3 will press the inclined surface of the triangular block 82, forcing it to move downward. After the positioning sleeve 3 is inserted, the spring piece 81 will drive the triangular block 82 to move upward and insert into the interior of the locking groove 83. At this time, the positioning sleeve 3 will be fixed, and the baffle 4 will block the top of the slot 12 and close the top opening of the slot 12.
