[0030] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0031] Embodiment 1:

[0032] This embodiment provides a safety net assembly for a scaffolding, characterized by comprising:

[0033] A main sliding rod 1, with the upper and lower ends of the main sliding rod 1 fixed to the scaffolding;

[0034] A fixed component 2, with the fixed component 2 fixed to the lower end of the main sliding rod 1;

[0035] A sliding component 3, with the sliding component 3 slidably arranged on the main sliding rod 1 and fixed to the main sliding rod 1 by a pin;

[0036] A mounting rod 4, with one end of the mounting rod 4 pivotally connected to the fixed component 2;

[0037] A diagonal tension rod 5, with one end of the diagonal tension rod 5 pivotally connected to the middle position of the mounting rod 4 and the other end pivotally connected to the sliding component 3;

[0038] Wherein, a safety net 6 is installed between two adjacent mounting rods 4 on the scaffolding.

[0039] The main body slide bar 1 is made of a hollow metal square bar, and a cross-shaped fastener is provided at each of the upper and lower ends of the main body slide bar 1. The main body slide bar 1 is fixed to the steel pipe of the scaffolding through the cross-shaped fastener, and the main body slide bar 1 can be disassembled and installed at any time through the cross-shaped fastener; the fixing component 2 is provided with a square fixing part, the fixing part is sleeved outside the main body slide bar 1, and the fixing component 2 is fixed to the main body slide bar 1 by two bolts passing through the fixing sleeve and the main body slide bar 1, and multiple installation reserved holes can be set to change the position of the fixing component 2; a sliding component 3 is also provided on the main body slide bar 1. The sliding component 3 is provided with a square sliding part, the sliding part is sleeved on the main body slide bar 1, and can slide on the main body slide bar 1. Pivoting parts with the same angle are provided on both the sliding part and the fixing part. When it is necessary to fix the sliding component 3, it is fixed by a pin passing through the sliding part and the main body slide bar 1. The pin can be disassembled and installed at any time, and a number of pin holes are provided on the main body slide bar 1 for fixing the sliding component 3 at different positions; one end of the installation rod 4 is pivotally connected to the first pivoting part 7 on the fixing component 2, and an inclined pulling part is provided at the middle position of the installation rod 4. One end of the inclined pulling rod 5 is pivotally connected and fixed to the inclined pulling part, and the other end of the inclined pulling rod 5 is pivotally connected and fixed to the second pivoting part in the sliding component 3. And the length of the inclined pulling rod 5 should be less than that of the installation rod 4. Preferably, the length of the inclined pulling rod 5 is half of the length of the installation rod 4, which can make the inclined pulling rod 5 control the swinging angle of the installation rod 4 larger and occupy less space when sliding. When using an inclined pulling rod 5 with the same length as the installation rod 4, when the installation rod 4 is retracted, the upper end of the inclined pulling rod 5 will be very high, which will unnecessarily extend the length of the main body slide bar 1; this structure is installed on the supporting steel pipes of several scaffolding, and a safety net 6 with a suitable size is provided between two adjacent installation rods 4.

[0040] During use, the angle of the installation rod 4 is changed by adjusting the position of the sliding component 3 on the main body slide bar 1. When the safety net 6 is perpendicular to the building, the effective area of the safety net 6 is the largest. When the safety net 6 is swung upward for adjustment, the dropped objects received by the safety net 6 can slide onto the platform of the scaffolding under the action of gravity, without the need for people to pick them up, avoiding danger; in the event of a typhoon, hail or other bad weather, by adjusting the sliding component 3 to slide upward, the installation rod 4 is made parallel to the scaffolding support rod, so that the safety net 6 is retracted to prevent damage caused by wind and hail and prevent damage to the safety net 6.

[0041] Embodiment 2:

[0042] This embodiment provides a protective net assembly for a scaffolding. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0043] At least two installation rods 4 are provided on the fixing component 2 at the turning point, and corresponding inclined pulling rods 5 are also provided between the sliding component 3 and the installation rods 4.

[0044] At the turning point of the scaffolding, the protective net component needs to be added with the following structure: there are at least two mounting rods 4 provided on the fixing component 2, and corresponding diagonal tension rods 5 are provided between the sliding component 3 and the mounting rods 4. For example, three first pivoting parts 7 with an included angle of 45 degrees are provided on the fixing component 2, and three second pivoting parts corresponding to the positions of the first pivoting parts 7 on the fixing component 2 are provided on the sliding component 3, and diagonal tension rods 5 and mounting rods 4 that cooperate with each other and are pivoted are provided. A triangular safety net 6 is provided between two adjacent mounting rods 4, so that the protective net can also be installed at the bending part of the scaffolding, and there is no unprotected dead angle in the effective range of the protective net.

[0045] At least two first pivoting parts 7 are provided on the fixing component 2, and a reinforcing rib plate 8 is provided between the two first pivoting parts 7.

[0046] Since the overall weight of the protective component is basically supported by the first pivoting part 7, the load-bearing capacity of the first pivoting part 7 is stronger through the reinforcing rib plate 8 and it is not easily damaged.

[0047] Embodiment 3:

[0048] This embodiment provides a protective net component for a scaffolding. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0049] It further includes:

[0051] And a first adjusting hole 10 for adjusting the position of the first limiting part 9 is provided on the main body sliding rod 1.

[0052] The arranged first limiting part 9 can prevent the lowest position of the sliding component 3. When the sliding component 3 abuts against the first limiting part 9, the mounting rod 4 is in a horizontal state, so that the safety net 6 is unfolded to the maximum, and the sliding component 3 cannot move downwards any more, resulting in the safety net 6 tilting outwards and not having the bearing capacity; and a first adjusting hole 10 is provided upwards at the position of the first limiting part 9 on the main body sliding rod 1. The number of the first adjusting holes 10 is at least two. By setting a plurality of first adjusting holes 10 as required, different lowest positions can be set for the sliding component 3.

[0053] The safety net 6 includes:

[0054] Two first net bodies 11, one side of the first net body 11 is arranged on the mounting rod 4;

[0055] A second net body 12, the second net body 12 is arranged between the two first net bodies 11 through a zipper.

[0056] The safety net 6 is divided into three parts. The first net bodies 11 on both sides are fixedly installed on the installation rods 4, and both sides of the second net body 12 are respectively connected to the first net bodies 11 through a zipper, making the safety net 6 easier to disassemble and install. Since the second net body 12 is most of the main body of the safety net 6, it is more likely to be damaged. By providing the second net body 12, the safety net 6 does not need to be replaced entirely, reducing replacement and saving costs, and the replacement is time-saving and labor-saving.

[0057] The inclined pull rod 5 includes a first telescopic rod 13 and a second telescopic rod 14. The second telescopic rod 14 is slidably arranged in the first telescopic rod 13 and fixed by bolts. A plurality of second adjustment holes 15 for adjusting the length of the inclined pull rod 5 are provided on the second telescopic rod 14.

[0058] The inclined pull rod 5 is arranged to be a telescopic structure. When the sliding assembly 3 is restricted and cannot move, the angle of the installation rod 4 can be adjusted by adjusting the length of the inclined pull rod 5. And a plurality of second adjustment holes 15 are provided on the second telescopic rod 14, and the second adjustment holes 15 enable the inclined pull rod 5 to be adjusted to more lengths.

[0059] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive.
