[0002] Existing scaffolding systems, constructed using metal frames, suffer from inconvenient assembly and disassembly, as well as instability. Therefore, it is necessary to strengthen the mutual tension and overall stability of the scaffolding on both sides to prevent excessive pressure on one side and tilting caused by worker movement and objects during construction. Simultaneously, the outer guardrails should be easy to assemble and disassemble while providing protection, and should distribute pressure evenly on both sides to prevent overall instability. Thus, a convenient guardrail structure for scaffolding assembly and disassembly is needed to address these issues. Utility Model Content

[0011] Preferably, the number of connectors is four, and two connectors are connected to both ends of one link.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The scaffolding features a conveniently assembled and disassembled guardrail structure. Through the installation of couplings, semi-square boxes, connectors, and connecting rods, the couplings on the device clamp onto the outer wall of the support frame. The connectors are connected inside the overlapping semi-square boxes, allowing two diagonally opposite connectors to connect to the same connecting rod. This ensures that when the entire device is under pressure, the cross-linking rods pull the supports on both sides together, preventing excessive pressure on one side and tilting.

By setting up limiting hoops, connecting nails, and sleeve hoops, when the two sleeve hoops on the device are clamped on the outer wall of the support, the two limiting hoops at the bottom are sleeved on the outer wall of the support and connected together by connecting nails. This allows the limiting hoops on the device to limit the sleeve hoops at the bottom, thereby stabilizing the sleeve hoops on the outer wall of the support. Attached Figure Description

[0021] 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.
[0022] Please see Figure 1-5 A scaffolding guardrail structure that is easy to assemble and disassemble includes: a support 1, a joint tube 2 connected to the top of the support 1, a mating groove 3 opened in the inner cavity of the joint tube 2, a connecting frame 4 connected to the outer wall of the support 1, a footrest 5 provided on one side of the support 1, a foot plate 6 provided on the inner wall of the footrest 5, an overlapping wall 7 connected to the outer wall of the footrest 5, a limiting hoop 8 sleeved on the outer wall of the support 1, a connecting nail 9 connected to the inner wall of the limiting hoop 8, a sleeve hoop 10 sleeved on the outer wall of the support 1, an inner arc wall 11 provided on the inner wall of the sleeve hoop 10, an extension wall 12 connected to the outer wall of the sleeve hoop 10, a semi-square box 13 connected to the outer wall of the extension wall 12, a through hole 14 opened in the outer wall of the semi-square box 13, a connecting screw 15 connected to the outer wall of the semi-square box 13, a connector 16 placed in the inner cavity of the semi-square box 13, and a connecting rod 17 connected to the outer wall of the connector 16.
[0023] The inner wall size of the connector tube 2 is adapted to the outer wall size of the bracket 1, and the bracket 1 is connected to another bracket 1 through the connector tube 2. The inner wall size of the connector tube 2 is adapted to the outer wall size of the bracket 1, so that when the bracket 1 on the device is laid on the construction site, it needs to be raised upwards. Another bracket 1 is used to support the top of the bracket 1 in the inner cavity of the connector tube 2, so that the bottom bracket 1 is connected to the top bracket 1 through the connector tube 2, thereby allowing the bracket 1 to be raised another layer.
[0024] The foot pedal 6 has drainage holes on its outer wall, and these holes are evenly distributed on the outer wall of the foot pedal 6. By having drainage holes on the outer wall of the foot pedal 6, when some impurities fall onto the outer wall of the foot pedal 6 during the construction process, some of the impurities will seep downward through the drainage holes on the outer wall of the foot pedal 6, thus preventing them from accumulating on the outer wall of the foot pedal 6.
[0025] Among them, there are several overlapping walls 7, and the inner wall of several overlapping walls 7 is adapted to the size of the outer wall of the connecting frame 4. Through several overlapping walls 7 on the device, the foot pedal 5 on the device is connected to the outer wall of the connecting frame 4 by multiple overlapping walls 7 on both sides, and the inner wall of the overlapping wall 7 is adapted to the curvature of the outer wall of the connecting frame 4, so that the foot pedal 5 on the device is stably placed between the connecting frames 4 on both sides.
[0026] Among them, the limiting clamps 8 are symmetrically arranged on the outer wall of the bracket 1, and the connecting nails 9 pass through the outer walls of the two limiting clamps 8. The limiting clamps 8 are symmetrically arranged on the outer wall of the bracket 1 through the device, so that the two limiting clamps 8 on the device are clamped on the outer wall of the bracket 1, and the limiting clamps 8 in the clamped state are connected by the two connecting nails 9, so that the limiting clamps 8 on the device are stably sleeved on the outer wall of the bracket 1.
[0027] Wherein; the sleeve 10 is connected to the half square box 13 through the extension wall 12, and the two half square boxes 13 overlap to form a square box. The sleeve 10 on the device is connected to the half square box 13 through the extension wall 12, so that when the two sleeve 10 on the device overlap, the half square box 13 on the other side will also overlap, so that when the half square box 13 on the device overlaps, the interior forms a square.
[0028] The through hole 14 is simultaneously opened on the inner and outer walls of the semi-square box 13 and the connector 16, and the outer wall of the connecting screw 15 is the same size as the inner wall of the through hole 14. By opening the through hole 14 on the inner and outer walls of the semi-square box 13 and the connector 16, the through hole 14 on the device is opened on the outer wall of the semi-square box 13 in a horizontal or vertical manner, and passes through the inner and outer walls of the connector 16 at the same time, so that the connecting screw 15 on the device is connected to the inner cavity of the through hole 14, thereby connecting the connector 16 and the semi-square box 13.
[0029] There are four connectors 16, and two connectors 16 are connected to both ends of a link 17. Through the four connectors 16 on the device, every two connectors 16 are connected to the same link 17. The four connectors 16 are set on the outer walls of the two supports 1. The same link 17 is connected by diagonal connectors 16, so that the link 17 on the device forms a cross shape between the two supports 1, thereby causing the link 17 on the device to pull the two supports 1.
[0030] The working principle is as follows: First, by setting up structures such as limiting clamps 8, connecting nails 9, and sleeve clamps 10, when the two sleeve clamps 10 on the device are clamped to the outer wall of the support 1, the two limiting clamps 8 at the bottom are sleeved on the outer wall of the support 1 and connected together by the connecting nails 9. This allows the limiting clamps 8 on the device to limit the sleeve clamps 10 at the bottom, thereby stabilizing the sleeve clamps 10 on the outer wall of the support 1. Then, by setting up sleeve clamps 10, semi-square boxes 13, connectors 16, and connecting rods 17... The structure allows the sleeve clamp 10 on the device to clamp onto the outer wall of the bracket 1, and the connector 16 is connected inside the overlapping half-square box 13, so that the two diagonally opposite connectors 16 are connected to the same connecting rod 17. Thus, when the device as a whole is under pressure, the cross connecting rod 17 pulls the brackets 1 on both sides to avoid excessive pressure on one side and tilting, so that the pressure is evenly distributed and the instability on one side is avoided. In addition, the front and rear connecting rods 17 are connected by threads, which is simple to operate and easy to disassemble and assemble.
