Description

Technical Field

[0001] This utility model relates to the field of safety net technology, specifically an adjustable safety net for building construction. Background Technology

[0002] Safety nets are protective devices used in high-altitude operations or construction. They are used to prevent people from falling or objects from falling. Safety nets generally have advantages such as long service life, blocking falling objects, and easy installation, and are therefore widely used in construction and other fields.

[0003] When using safety nets, their length needs to be adjusted according to the needs of the construction site. However, most existing safety nets require workers to adjust them, and the adjustment process involves removing and installing the safety nets from different steel pipes, which slows down the installation efficiency and reduces construction efficiency. Therefore, an adjustable safety net for construction is proposed to solve the above-mentioned problems. Utility Model Content

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.

[0027] In the embodiments, by Figure 1-4 An adjustable safety net for building construction is provided. The present invention includes an outer shell 1, a motor 2 fixedly connected inside the outer shell 1, a horizontal shaft 3 fixedly connected to the output end of the motor 2, a first gear 4 fixedly connected to the outer side of the horizontal shaft 3, a support block 5 fixedly connected to the left side of the outer shell 1, a threaded long rod 6 rotatably connected inside the support block 5, a short shaft 7 fixedly connected to the top of the threaded long rod 6, a second gear 8 fixedly connected to the outer side of the short shaft 7, the first gear 4 and the second gear 8 meshing with each other, a moving block 9 threadedly connected to the outer side of the threaded long rod 6, a horizontal block 10 fixedly connected to the left side of both the support block 5 and the moving block 9, and a base 11 fixedly connected to the top and bottom of both horizontal blocks 10, wherein a safety net body 12 is provided on the opposite side of the two bases 11.

[0028] A load-bearing block is fixedly connected to the right side of the outer casing 1, and the inside of the load-bearing block is equipped with a number of bolts;

[0029] The support block 5 has a positioning groove 13 inside, and a positioning block 14 is fixedly connected to the bottom of the support block 5.

[0030] The positioning slot 13 allows the positioning block 14 to be inserted into the support block 5.

[0031] The inner part of the outer casing 1 is rotatably connected to a threaded short rod 15, and the outer side of the threaded short rod 15 is threadedly connected to a limit block 16;

[0032] The limiting block 16 can be extended and retracted through the threaded short rod 15;

[0033] The interior of the outer casing 1 is provided with a steel pipe 17, and the bottom of the threaded short rod 15 is fixedly connected to an extension shaft 18;

[0034] The threaded short rod 15 can be rotated by extending the shaft 18;

[0035] The bottom of the extension shaft 18 is fixedly connected to a first locking block 19, and a second locking block 20 is locked inside the first locking block 19;

[0036] The second locking block 20 enables the first locking block 19 to drive the extension shaft 18 to rotate;

[0037] The bottom of the second card block 20 is fixedly connected to a handle 21, which is located at the bottom of the outer casing 1;

[0038] The second locking block 20 can be easily rotated under force by the throttle 21.

[0039] Working principle:

[0040] Step 1: Move the outer shell 1 laterally so that the steel pipe 17 is inside the outer shell 1. Then, engage the second locking block 20 with the first locking block 19 and turn the handle 21 to make the handle 21 drive the second locking block 20 to rotate. The rotation of the second locking block 20 drives the first locking block 19 to rotate. The first locking block 19 drives the threaded short rod 15 to rotate through the extension shaft 18. The rotation of the threaded short rod 15 drives the limiting block 16 to extend, thereby limiting the steel pipe 17 inside the outer shell 1. Then, connect the bolts to the construction site so that the outer shell 1 can easily bear the force.

[0041] Step 2: Restart motor 2, causing the output end of motor 2 to drive the horizontal shaft 3 to rotate. The rotation of the horizontal shaft 3 drives the first gear 4 to rotate, which in turn drives the short shaft 7 to rotate through the second gear 8. The rotation of the short shaft 7 drives the threaded rod 6 to rotate, which in turn drives the moving block 9 to rise and fall. This causes the moving block 9 to move the base 11 through the bottom horizontal block 10, allowing the distance between the two bases 11 to be adjusted. This facilitates the adaptation of safety net bodies 12 of different sizes. Multiple outer support blocks 5 are connected in series through the positioning block 14 and the positioning groove 13, so that the base 11 on the opposite side of the two horizontal blocks 10 can be used to install the safety net body 12, making the safety net body 12 a whole.
