Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a protective device for building construction. Background Technology

[0002] A search revealed that Chinese Patent No. 202020939590.5 discloses a protective device for building construction. This device is movably connected between two U-shaped guardrails via a limiting block and a movable rod, allowing the protective width of the device to be freely changed. This solves the problem that existing protective devices generally have a fixed length and are difficult to adjust the protective width according to the needs of different sites, resulting in insufficient flexibility in use.

[0003] In the field of construction, workers often use protective devices at construction sites to warn and protect pedestrians and vehicles. However, the internal structure of existing protective devices is basically fixed and it is not easy to achieve a foldable function. This results in the protective devices taking up a large area, making it inconvenient for workers to carry or store them, which greatly reduces the convenience of the protective devices.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a protective device for construction, including a base plate 1 and screws 2. Screws 2 are movably inserted into the outer side of the base plate 1. Through the cooperation of four sets of screws 2, workers can control a pre-prepared electric screwdriver to rotate the screws 2 downwards along the interior of the base plate 1 until a portion of the screw 2 passes through the lower surface of the base plate 1, and finally firmly rotates into the ground. This effectively fixes the base plate 1 to the ground, improving the stability of the device during use. A fixing block 3 is fixedly connected to the outer side of the upper surface of the base plate 1, and a rod is movably inserted into the top of the outer side of the fixing block 3. 4. A tension spring 5 is sleeved on the outer side of the outer surface of the insertion rod 4. A short shaft 6 is movably inserted into the bottom of the outer side of the fixing block 3. A first protective plate 7 is fixedly connected to the inner end of the short shaft 6. An insertion hole 8 is opened at the bottom of the outer side of the first protective plate 7. The insertion rod 4 is movably inserted into the insertion hole 8. A second protective plate 9 is provided on the upper surface of the first protective plate 7. A hinge 10 is provided on the inner side of the back of the first protective plate 7 and the second protective plate 9. A connecting groove 11 is opened at the bottom of the outer side of the second protective plate 9. A limit hole 12 is opened on the inner wall of the connecting groove 11. A connecting block 13 is fixedly connected to the upper surface of the first protective plate 7. A limit rod 14 is movably inserted into the outer side of the connecting block 13. By controlling the limiting rod 14 to move out of the limiting hole 12, the fixation of the second protective plate 9 is released. Then, the second protective plate 9 is controlled to rotate 180 degrees to the rear. Then, the insertion rod 4 is controlled to be pulled out of the insertion hole 8. Then, the first protective plate 7 is controlled to rotate 90 degrees to the front. This realizes the folding function of the device, reducing the footprint of the device and making it easier for staff to carry or store, greatly improving the convenience of the device. The limiting rod 14 is movably inserted into the limiting hole 12. The inner end of the limiting rod 14 is fixedly connected to the moving block 15. The moving block 15 is slidably connected to the connecting block 13. The front side of the outer surface of the moving block 15 A handheld rod 16 is fixedly connected and extends through the front of the connecting block 13. A short rod 17 is fixedly connected to the inner side of the moving block 15. A return spring 18 is sleeved on the outer surface of the short rod 17. The reaction force generated by the compression of the return spring 18 continuously compresses the moving block 15 outward, causing the moving block 15 to drive the limiting rod 14 to move outward along the inside of the connecting block 13 until the limiting rod 14 passes through the outer side of the connecting block 13 and is finally firmly inserted into the inside of the limiting hole 12. This improves the fixing effect between the connecting block 13 and the second protective plate 9 and indirectly ensures the stability of the device when it is used.

[0025] In order to facilitate the operation of the handheld lever 16 by the staff, a through groove is provided in the middle of the front side of the connecting block 13. The inner diameter of the through groove is adapted to the outer diameter of the handheld lever 16, which facilitates the operation of the handheld lever 16 by the staff.

[0026] In order to extend the service life of the tension spring 5 and the return spring 18, this utility model sets the number of tension spring 5 and return spring 18 to two sets and one set, respectively. The tension spring 5 and the return spring 18 are both made of silicon manganese spring steel. Springs made of silicon manganese spring steel have good return effect and are not easily deformed, thus extending the service life of tension spring 5 and return spring 18.

[0027] In order to facilitate the movement of the movable block 15 along the interior of the connecting block 13, a moving groove is provided inside the connecting block 13. The inner diameter of the moving groove is adapted to the outer diameter of the movable block 15, which facilitates the movement of the movable block 15 along the interior of the connecting block 13.

[0028] In order to improve the stability of the connection between the fixing block 3 and the base plate 1, this utility model has a triangular block fixedly connected to the bottom of the outer side of the fixing block 3. The lower surface of the triangular block is fixedly connected to the upper surface of the base plate 1. The triangular block increases the connection area between the fixing block 3 and the base plate 1, thereby improving the stability of the connection between the fixing block 3 and the base plate 1.

[0029] To ensure that the connecting block 13, limiting rod 14, moving block 15, handheld rod 16, and short rod 17 are not easily damaged during use, the materials used to make the connecting block 13, limiting rod 14, moving block 15, handheld rod 16, and short rod 17 are all stainless steel. Stainless steel has high hardness and is not easily deformed, thus ensuring that the connecting block 13, limiting rod 14, moving block 15, handheld rod 16, and short rod 17 are not easily damaged during use.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0031] During use, the operator uses a pre-prepared electric screwdriver to rotate screw 2 downwards along the inside of the base plate 1 until it is inserted into the ground, thus fixing the base plate 1 to the ground and completing the installation of the device. This provides protection for the construction site. Then, when folding the device, the operator controls the hand lever 16 to move the moving block 15 and the limiting rod 14 inwards along the inside of the connecting block 13. Simultaneously, the moving block 15 moves the short rod 17 inwards to press the return spring 18 until the limiting rod 14 moves out of the limiting hole 12, releasing the connection between the connecting groove 11 and the connecting block 13. The first protective plate 7 is fixed, and the second protective plate 9 is released. Then, due to the hinge 10, the second protective plate 9 can rotate. Then, the second protective plate 9 is rotated 180 degrees to the rear, so that the back of the second protective plate 9 is in close contact with the back of the first protective plate 7. Then, the insertion rod 4 is moved outward from the inside of the insertion hole 8, and the tension spring 5 is stretched outward to release the fixation between the fixing block 3 and the first protective plate 7. Then, the first protective plate 7 is controlled to drive the short shaft 6 to rotate 90 degrees forward along the inside of the fixing block 3 until the front of the first protective plate 7 is in close contact with the upper surface of the base plate 1. This completes the folding of the device.

[0032] In summary, this construction safety device, by controlling the limiting rod 14 to move out of the limiting hole 12, releases the fixation on the second protective plate 9, then controls the second protective plate 9 to rotate 180 degrees to the rear, then controls the insertion rod 4 to pull out of the insertion hole 8, and then controls the first protective plate 7 to rotate 90 degrees to the front, thus realizing the folding function of the device, reducing the footprint of the device, making it easier for workers to carry or store, and greatly improving the convenience of the device.

[0033] The protective device for construction uses the reaction force generated by the compression of the return spring 18 to continuously compress the moving block 15 outward, causing the moving block 15 to drive the limiting rod 14 to move outward along the inside of the connecting block 13 until the limiting rod 14 passes through the outer side of the connecting block 13 and is finally firmly inserted into the inside of the limiting hole 12. This improves the fixing effect between the connecting block 13 and the second protective plate 9, and indirectly ensures the stability of the device when it is used.

[0034] This construction safety device, through the cooperation of four sets of screws 2, allows workers to control a pre-prepared electric screwdriver to rotate the screws 2 downwards along the inside of the base plate 1 until part of the screw 2 passes through the lower surface of the base plate 1 and is finally firmly rotated into the ground. This effectively fixes the base plate 1 to the ground and improves the stability of the device when it is in use.
