Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a conversion device that can be used to convert protective nets of different specifications. Background Technology

[0002] Climbing scaffolding has developed rapidly as a high-altitude safety product, especially all-steel attached lifting scaffolding. Due to the large number of manufacturers, the specifications of their all-steel safety nets vary, with sizes such as 1m*2m, 1.5m*2.5m, 2m*2m, and 1m*1.5m. This discrepancy in specifications leads to a large amount of unused safety net inventory, resulting in low turnover. Meanwhile, the safety nets available for ongoing scaffolding construction are insufficient, necessitating additional purchases and increasing construction safety costs. Utility Model Content

[0003] This invention proposes a conversion device that can be used to convert protective nets of different specifications, thereby improving the conversion of protective nets of different specifications and reducing the protection cost of construction.

[0004] The technical solution of this utility model is implemented as follows: A conversion device for converting protective nets of different specifications includes a connecting cylinder. One end of the connecting cylinder is fixed with a connecting plate along the axial direction. Two U-shaped buckles are provided at the end of the connecting plate away from the connecting cylinder. The opening ends of the two U-shaped buckles face the connecting cylinder. The two U-shaped buckles are located on both sides of the connecting plate. The connecting plate is also provided with a plug hole, which is located between the U-shaped buckle and the connecting cylinder. A pin is inserted into the plug hole. The other end of the connecting cylinder is connected to a connector through a corner fastener.

[0005] Furthermore, the insertion hole is an elongated hole, the pin is a right-angled trapezoidal plate, and a limiting hole is provided at the shorter end of the pin, into which a cotter pin is inserted.

[0006] Furthermore, the two U-shaped buckles are staggered, and the two U-shaped buckles are integrated with the connecting plate into a single structure.

[0007] Furthermore, the connector includes a cylinder, one end of which is connected to a corner fastener, and the other end is fixed with a connecting plate, on which strip-shaped holes are spaced apart.

[0008] Furthermore, the corner fastener is a cross-shaped fastener, which includes two clamps that are vertically and fixedly connected. One clamp is fixed to the cylinder, and the other clamp is fixed to the connecting cylinder.

[0009] Furthermore, the corner fastener includes a clamp fixed to the connecting cylinder, a support plate fixed to the clamp, and a connecting hole provided on the support plate.

[0010] Furthermore, the connector includes a connecting plate, on which strip-shaped holes are spaced apart.

[0011] The beneficial effects of this utility model are:

[0012] This utility model's conversion device assembles two protective nets of different specifications together using two U-shaped buckles. The use of insertion holes and pins prevents the net's frame from detaching from the U-shaped buckles. Corner fasteners and connectors connect the connecting cylinder to the uprights or horizontal bars of the scaffold, thus fixing the assembled protective net to the scaffold. This allows for arbitrary connection positions, enabling the conversion of different specifications of all-steel protective nets, improving the conversion efficiency of the protective net, and reducing construction protection costs.

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figure 2 and 5 As shown, a conversion device for converting protective nets of different specifications includes a connecting cylinder 1. A connecting plate 2 is fixed to one end of the connecting cylinder 1 along the axial direction. Two U-shaped buckles 3 are provided at the end of the connecting plate 2 away from the connecting cylinder 1. The open ends of the two U-shaped buckles 3 face the connecting cylinder 1. The two U-shaped buckles 3 are located on both sides of the connecting plate 2 and are staggered. The two U-shaped buckles 3 and the connecting plate 2 are integrated into one structure, that is, the end of the connecting plate 2 is cut along the axial direction and bent to both sides to form U-shaped buckles 3.

[0025] like Figure 2 , 3 As shown in Figure 5, the connecting plate 2 is also provided with a socket 4. The socket 4 is located between the U-shaped buckle 3 and the connecting cylinder 1. A pin 5 is inserted into the socket 4. The socket 4 is an elongated hole, and the pin 5 is a right-angled trapezoidal plate. A limiting hole 6 is provided at the shorter end of the pin 5. A cotter pin 7 is inserted into the limiting hole 6 so that the shorter end of the pin 5 passes through the socket 4. Then the cotter pin 7 passes through the limiting hole 6 to prevent the pin 5 from falling out of the socket 4.

[0026] like Figure 1 , 2 As shown in Figure 4, the other end of the connecting cylinder 1 is connected to a connecting member via a corner fastener. The connecting member includes a cylinder 8, one end of which is connected to the corner fastener, and the other end is fixed with a connecting plate 9. The connecting plate 9 has slotted holes 10. The corner fastener is a cross fastener 11, which includes two clamps 14. The two clamps 14 are vertically fixed together, one clamp 14 is fixed to the cylinder 8, and the other clamp 14 is fixed to the connecting cylinder 1.

[0027] The method of using the conversion device is as follows: Figure 2 As shown, place the frames 17 of the two protective nets on both sides of the connecting plate 2, then pull the connecting cylinder 1 so that the U-shaped buckle 3 is snapped onto the frame 17 of the protective net on the same side. Then, pass one end of the pin 5 through the insertion hole 4 to restrict the frame 17 of the protective net within the U-shaped buckle 3. Pass the cotter pin 7 through the limiting hole 6 to prevent the pin 5 from falling off. Connect the connector to the cylinder 8 through the corner fastener, and bolt the strip hole 10 on the connecting plate 9 to the upright 12 or horizontal bar 13 of the scaffold. Figure 1 and4 As shown.

[0028] Example 2

[0029] This embodiment is basically the same as Embodiment 1, except that: Figure 6 and 7 As shown, the corner fastener includes a clamp 14, on which a support plate 15 is fixed. The support plate 15 has a connecting hole 16. The connector includes a connecting plate 9, on which slotted holes 10 are spaced apart. The clamp 14 is fixed to the connecting cylinder 1. One end of the slotted hole 10 of the connecting plate 9 is bolted to the upright 12 or horizontal bar 13 of the scaffold, and the other end of the slotted hole 10 is bolted to the connecting hole 16.
