A construction site ground safety fence

Abstract

This utility model discloses a safety fence for construction site foundations, including a first post and a second post, and a first base fixedly installed at the bottom of the first post and the second post. The insertable guardrail is inserted into the storage channel. Through the design of the fixed guardrail, the insertable guardrail, the first post, and the second post, this utility model creates a storage channel within the fixed guardrail and inserts the insertable guardrail into it. By moving the insertable guardrail with the second post, the depth of insertion within the fixed guardrail can be adjusted. This allows for flexible adjustment of the overall length of the fence according to the actual area to be protected, enabling rapid expansion or contraction of the fence. This avoids safety loopholes caused by a fixed-length fence not being able to cover the area, and eliminates the need for frequent replacement of the entire fence due to changes in the protected area, reducing material waste and equipment idle costs.

[0030] In an optional embodiment: the fixing mechanism 12 includes a connecting block 1201, a fixing seat 1202, a connecting seat 1205, and a threaded post 1206. The fixing seat 1202 is fixedly connected to the side of the connecting block 1201. A limiting groove 20 adapted to the fixing seat 1202 is opened in the positioning insert 8. The fixing seat 1202 is inserted into the limiting groove 20. The connecting seat 1205 is fixedly connected to the end of the threaded post 1206. The threaded post 1206 is threadedly installed inside the connecting block 1201. A through hole is opened in the fixing seat 1202. One end of the threaded post 1206 passes through the through hole and is connected to the fixing guardrail 2. The end of the threaded post 1206 abuts against the side of the inserted guardrail 7.

[0031] It should be noted that the connecting block 1201, the fixing seat 1202, the retaining ring 1204 and the threaded post 1206 are used to fix the fixed guardrail 2 and the plug-in guardrail 7 after adjustment.

[0032] In an optional embodiment, the fixing mechanism 12 further includes a retaining edge 1203 and a retaining ring 1204. The retaining edge 1203 is fixedly connected to the top of the fixing seat 1202, the bottom of the retaining edge 1203 contacts the top of the positioning insert 8, the retaining ring 1204 is fixedly connected to the side of the connecting block 1201, and the connecting seat 1205 is disposed inside the retaining ring 1204.

[0033] It should be noted that the baffle 1203 serves to position the fixed seat 1202, preventing the fixed seat 1202 from falling out of the positioning block 8, while also facilitating the alignment of the threaded post 1206 with the through hole. The retaining ring 1204 ensures that the connecting seat 1205 is located within the retaining ring 1204, thereby preventing others from disassembling the connecting seat 1205 with tools.

[0034] In an optional embodiment, it also includes an adjustment handle 21, on the side of which a square post 22 is fixedly connected. The inside of the connecting seat 1205 is provided with a square groove 23 that is adapted to the square post 22, and the square post 22 is inserted into the square groove 23.

[0035] It should be noted that by adjusting the handle 21 in conjunction with the square post 22, the connector 1205 can be disassembled or installed using a suitable tool. After disassembling or installing the connector 1205, the adjustment handle 21 can be removed to prevent others from disassembling the connector 1205.

[0036] In an optional embodiment: the top and bottom of the plug-in guardrail 7 are provided with clearance grooves 14, and the surfaces of the clearance grooves 14 are fixedly connected in pairs to a number of blocks 10 corresponding to the positioning plugs 8, and the positioning plugs 8 are plugged into the two sets of blocks 10.

[0037] It should be noted that the stop block 10 is used to position the positioning plug 8, thereby improving the fixing effect of the positioning plug 8 after installation.

[0038] In an optional embodiment: the inner top and inner bottom of the storage channel 11 are fixedly installed with multiple sets of mounting seats 13 in a rectangular array, and each set of mounting seats 13 is movably installed with a roller 15, the surface of the roller 15 contacting the clearance groove 14.

[0039] It should be noted that by setting the roller 15, when adjusting the plug-in guardrail 7 from inside the fixed guardrail 2, the friction between the plug-in guardrail 7 and the fixed guardrail 2 is reduced, making it easier to adjust the plug-in guardrail 7 and the fixed guardrail 2.

[0040] In an optional embodiment, a second base 19 is also included. A movable seat 17 is fixedly installed on the top of the second base 19. The movable seat 17 is sleeved on the bottom of the fixed guardrail 2. Guide blocks 16 are fixedly connected to both sides of the fixed guardrail 2 near the movable seat 17. A guide groove 18 adapted to the guide groove 18 is opened in the movable seat 17. The guide blocks 16 are disposed inside the guide groove 18. The movable seat 17 is fixedly installed at the bottom of the fixed guardrail 2.

[0041] It should be noted that the guide block 16 and the guide groove 18 cooperate to position the movable seat 17, so that the movable seat 17 can be stably adjusted at the bottom. The movable seat 17 cooperates with the second base 19 to fix the fence again, thereby improving the installation effect of the fence.

[0042] The usage process of this utility model is as follows: When adjusting the length of the fence according to the actual size of the protected area, the fixing parts that fix the first base 4 and the second base 19 are disassembled, the adjustment handle 21 is rotated, and when the adjustment handle 21 is rotated, the connecting seat 1205 is rotated through the square column 22. When the connecting seat 1205 rotates, it moves out of the connecting block 1201, and the fixing seat 1202 is moved out of the positioning plug 8. The positioning plug 8 is moved out of the fixed guardrail 2. The second column 3 moves the insertion guardrail 7, thereby adjusting the depth of the insertion guardrail 7 in the fixed guardrail 2. Thus, the overall length of the fence can be flexibly adjusted according to the actual size of the protected area, and the fence can be quickly expanded or contracted.

[0043] After adjusting the fence, fine-tune the plug-in guardrail 7 so that the positioning hole 9 on the plug-in guardrail 7 is aligned with the positioning hole 9 on the fixed guardrail 2. Insert the positioning block 8 into the positioning hole 9. After the positioning block 8 is inserted into the positioning hole 9, one end of the positioning block 8 extends to the outside of the fixed guardrail 2. Insert the fixing seat 1202 into the limiting groove 20. The baffle 1203 contacts the top of the positioning block 8. By inserting the square post 22 into the square groove 23, rotate the adjusting handle 21 so that the threaded post 1206 is threaded into the connecting block 1201. After the end of the threaded post 1206 passes through the through hole and is inserted into the fixed guardrail 2, the end of the threaded post 1206 abuts against the side of the plug-in guardrail 7, thereby adjusting and fixing the fixed guardrail 2 and the plug-in guardrail 7.

[0044] Adjust the second base 19 so that it moves to the middle position between the fixed guardrail 2 and the plug-in guardrail 7 via the movable seat 17. Fix the movable seat 17 to the bottom of the fixed guardrail 2 using the fastener. Fix the first base 4 and the second base 19 to the ground using the fastener. At this point, the adjustment and fixing of the fence is completed.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
