[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0023] The following describes the fixing device for the external steel mesh frame according to an embodiment of the present invention.

[0024] like Figures 1 to 3 As shown, the fixing device for the external steel mesh frame of this utility model embodiment includes: metal plate 1, fastener 2, bolt 3, nut 4 and clip.

[0025] First, let's describe the metal plate 1 and the fastener 2. The metal plate 1 has a first arc-shaped groove 11 near its rear end, and a through hole 12 is formed on the front side of the first arc-shaped groove 11. The rear end of the fastener 2 is hinged to the rear end of the metal plate 1. The fastener 2 has a second arc-shaped groove 21 near its front end. The first arc-shaped groove 11 and the second arc-shaped groove 21 cooperate to accommodate the crossbar 7. The front end of the fastener 2 has a notch 22. The front, back, left, and right sides are... Figure 1 As shown in the attached figures, please refer to the other accompanying figures. Figure 1 .

[0026] like Figure 2 As shown, a first arc-shaped groove 11 is stamped or machined near the rear end of the metal plate 1. The first arc-shaped groove 11 is used to fit the side of the crossbar 7 of the scaffold. A through hole 12 is opened in front of the first arc-shaped groove 11.

[0027] The fastener 2 has a corresponding second arc-shaped groove 21. When fastened, the first arc-shaped groove 11 and the second arc-shaped groove 21 together form a complete circular or elliptical hole, which holds the crossbar 7 tightly. The front end of the fastener 2 has a notch 22.

[0028] The rear end of fastener 2 is hinged to the rear end of metal plate 1, making it easy to connect metal plate 1 and fastener 2.

[0029] Next, the bolt 3 and nut 4 will be described. The bolt 3 passes through the through hole 12 and the notch 22 from below and is threadedly connected to the nut 4 above.

[0030] During installation, first, engage the first arc-shaped groove 11 of the metal plate 1 with the crossbar 7. Then, rotate the fastener 2 so that its second arc-shaped groove 21 also engages with the crossbar 7. Next, pass the bolt 3 through the through hole 12 of the metal plate 1 and the recess 22 of the fastener 2 from below, and finally tighten the nut 4. Tighten the nut 4 with a wrench to ensure that the metal plate 1 and the fastener 2 tightly clamp the crossbar 7.

[0031] Finally, the snap fastener is described. The snap fastener is attached to the front end of the metal plate 1, and has a locking slot to engage the frame 81. The snap fastener can be the upper snap fastener 51 and / or the lower snap fastener 52, as described later.

[0032] The snap-fit ​​frame 81 of the outer steel mesh frame ensures a secure connection between the outer steel mesh frame and the fixing device.

[0033] The above-mentioned fixing device for the external scaffold steel mesh uses the arc-shaped grooves on the metal plate 1 and fastener 2 to engage and be locked by bolts 3 and nuts 4, which can firmly hold the horizontal bars 7 of the scaffold. Simultaneously, a specialized snap-fit ​​structure stably secures the frame 81 of the steel mesh, providing double fixing and effectively preventing the steel mesh from loosening or falling off. This ensures a firm and reliable connection between the external scaffold steel mesh and the horizontal bars 7 of the scaffold.

[0034] The system employs hinged fasteners 2 and bolts 3 for fastening, eliminating the need for complex tools. Installation and disassembly can be completed quickly by hand or with a simple wrench, significantly improving construction efficiency. This results in convenient and efficient disassembly.

[0035] The snap-fit ​​design can adapt to different installation positions and orientations of the frame 81, offering good versatility and thus good applicability.

[0036] In some embodiments of this utility model, the buckle further includes an upper buckle 51. The upper buckle 51 includes a first vertical plate and a first horizontal plate. The bottom end of the first vertical plate is connected to the front end of the metal plate 1, and the front end of the first horizontal plate is connected to the top end of the first vertical plate. The first horizontal plate, the first vertical plate, and the front end of the metal plate 1 form an upper latch.

[0037] like Figure 1 and Figure 3 As shown, the upper latch of the upper buckle 51 can conveniently and stably engage the upper frame 81 of the outer frame steel mesh.

[0038] Furthermore, the buckle also includes a lower buckle 52. The lower buckle 52 includes a second vertical plate and a second horizontal plate. The top of the second vertical plate is connected to the front end of the metal plate 1, and the front end of the second horizontal plate is connected to the bottom end of the second vertical plate. The second horizontal plate, the second vertical plate, and the front end of the metal plate 1 form a lower latch.

[0039] like Figure 1 and Figure 3As shown, the lower latch of the lower buckle 52 can conveniently and stably engage the lower frame 81 of the outer frame steel mesh.

[0040] The buckle includes an upper buckle 51 and a lower buckle 52. The upper buckle 51 is composed of a first vertical plate and a first horizontal plate, which together with the front end of the metal plate 1 form an upper latch. The lower buckle 52 is composed of a second vertical plate and a second horizontal plate, which together with the front end of the metal plate 1 form a lower latch. The upper buckle 51 and the lower buckle 52 are located on the left and right sides of the metal plate 1, respectively. The frame 81 of the outer steel mesh can be snapped into the upper or lower latch as needed, thereby realizing the quick connection between the steel mesh and the fixing device.

[0041] Furthermore, the upper buckle 51 and the lower buckle 52 are respectively provided on the left and right sides of the metal plate 1.

[0042] like Figure 1 As shown, the upper buckle 51 is set on the right side of the metal plate 1, and the lower buckle 52 is set on the left side of the metal plate 1.

[0043] Furthermore, the metal plate 1, the upper buckle 51, and the lower buckle 52 are integrally formed.

[0044] The steel plate can be cut in the left and right directions at its end to form a left part and a right part. The left part is bent downwards to form a lower buckle 52, and the right part is bent upwards to form an upper buckle 51. The unbent part is used to form the metal plate 1. This increases the ease of manufacturing and reduces costs.

[0045] In some embodiments of this utility model, a strip-shaped insertion hole 13 in the front-rear direction is formed near the front end of the metal plate 1, and the fixing device also includes a pin 6. The pin 6 is inserted into the insertion hole, and the width of the pin 6 in the front-rear direction gradually increases from the bottom to the top. The width of the top of the pin 6 in the front-rear direction is greater than the length of the strip-shaped insertion hole 13, and the width of the bottom of the pin 6 in the front-rear direction is less than the length of the strip-shaped insertion hole 13.

[0046] like Figure 1 and Figure 3 As shown, to prevent the frame 81 from accidentally dislodging from the latch, a strip-shaped insertion hole 13 in the front-rear direction is opened near the front end of the metal plate 1. A wedge-shaped pin 6 can be inserted into this insertion hole. The width of the pin 6 gradually increases from bottom to top. After the frame 81 is inserted into the latch, the pin 6 is inserted from the bottom (the narrower end) of the strip-shaped insertion hole 13. Since the top width of the pin 6 is greater than the length of the strip-shaped insertion hole 13, when the pin 6 is struck to a certain depth, its wider part will form an interference fit with the hole wall of the strip-shaped insertion hole 13, and abut against the frame 81 and the steel mesh 82 that are already inserted into the latch, using friction and pressure to prevent the frame 81 and the steel mesh 82 from dislodging from the latch.

[0047] Furthermore, an anti-loosening protrusion 61 is formed on the bottom side of the pin 6.

[0048] like Figure 1 and Figure 3 As shown, the bottom side of the pin 6 is provided with an anti-detachment protrusion 61, which can be locked on the outside of the strip socket 13 to prevent the pin 6 from being completely lost after passing through the strip socket 13.

[0049] Furthermore, the pin 6 has a strip-shaped notch 62 in the front-to-back direction at a position adjacent to the anti-detachment protrusion 61.

[0050] like Figure 1 and Figure 3 As shown, a strip-shaped notch 62 is formed on the pin 6. This notch 62 increases the elasticity of the pin 6, making it easier to undergo elastic deformation when inserted into the strip-shaped socket 13, thereby facilitating installation and ensuring a locking effect.

[0051] In some embodiments of this utility model, one end of the strip-shaped socket 13 is formed into an arc shape.

[0052] like Figure 2 As shown, the end of the strip-shaped socket 13 can be machined into an arc shape to better match the shape of the pin 6 and disperse stress.

[0053] In some embodiments of this utility model, a connecting hole 14 is formed at the rear end of the metal plate 1, and an insert 23 is formed at the rear end of the fastener 2. The insert 23 can be inserted into the connecting hole 14 and can rotate so that the fastener 2 and the metal plate 1 are hinged.

[0054] like Figure 2 As shown, the rear end of the metal plate 1 is provided with a connecting hole 14. The rear end of the fastener 2 is provided with an insert 23. By inserting the insert 23 into the connecting hole 14, the fastener 2 and the metal plate 1 are hinged, allowing the fastener 2 to rotate around the insert 23.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
