The transmission mechanism includes a first bevel gear fixedly provided on the outer wall of the threaded rod, a second bevel gear meshingly connected to one side of the first bevel gear, and a rotating rod fixed in the second bevel gear. The crank handle is fixed at one end of the rotating rod away from the second bevel gear. The first bevel gear and the second bevel gear are both located inside the base. A ring is fixedly provided on the outer wall of the rotating rod, and the ring is rotatably connected in the base.

[0011] By adopting the above technical solution, people will drive the rotating rod and the second bevel gear to rotate after shaking the handle, and the second bevel gear will drive the meshing first bevel gear to rotate after rotating, and the first bevel gear will drive the threaded rod to rotate after rotating.

[0012] Optionally, the protection mechanism includes a nut threaded on the top of the threaded rod, and a soft component fixed on the top of the outer wall of the nut.

[0013] By adopting the above technical solution, when people accidentally touch the top of the threaded rod during construction, the soft part will provide buffer protection for people, making it difficult for people to get injured, and the nut makes it convenient to disassemble and assemble the soft part at the top of the threaded rod.

[0014] In summary, the present invention has at least one of the following beneficial effects:

[0015] 1. By shaking the handle and cooperating with the transmission of the transmission mechanism, the threaded rod can be driven to rotate, and in conjunction with the limit of the vertical pole, the guardrail can be driven to move up and down to adjust the height of the guardrail. The height-adjusted guardrail can meet the protection needs of people of different heights and has a wide range of applications. On the whole, people only need to shake the handle to complete the height adjustment process of the guardrail, which is simple and practical.

[0016] 2. Through the protection of soft parts, people are not easily injured after accidentally touching the top of the threaded rod during construction, which improves safety. The nut facilitates the disassembly and assembly of the soft parts at the top of the threaded rod, and people can remove parts such as guardrails and protective nets from the scaffolding body as a whole for maintenance and replacement, which is convenient for use.

[0022] The following is combined with Figure 1-4 The utility model is described in further detail.

[0023] The utility model embodiment discloses a scaffolding guardrail structure, referring to Figure 1-3 , including a scaffolding body 1, a guardrail installed on the top of the scaffolding body 1, and an adjustment mechanism installed on the top of the scaffolding body 1 and used to adjust the height of the guardrail. A plurality of vertical poles 2 are fixedly provided at the top edge of the scaffolding body 1. The guardrail includes a guardrail 21 slidably arranged between adjacent vertical poles 2. Two adjacent vertical poles 2 can limit the guardrail 21 so that the guardrail 21 can only be raised and lowered.

[0024] Reference Figure 1 , Figure 2 and Figure 4 A collar 22 is fixedly provided on both sides of the guardrail 21, and the collar 22 is slidably provided on the outer wall of the upright 2. A protective net 23 is fixedly provided on one side of the guardrail 21. The collar 22 can connect the guardrail 21 with the upright 2. The guardrail 21 is in the shape of a "mouth", and the protective net 23 can fill and block the internal gap of the guardrail 21 to improve the protective effect of the guardrail.

[0025] Reference Figure 1-3 The adjusting mechanism includes a base 3 fixedly installed at the top edge of the scaffolding body 1, and a threaded rod 31 rotatably arranged in the base 3. A bearing 32 is fixedly arranged at the bottom inner side of the base 3. The bottom end of the threaded rod 31 is rotatably connected in the bearing 32. The bearing 32 can connect the base 3 and the threaded rod 31 and reduce the resistance of the threaded rod 31 during rotation. Multiple adjusting mechanisms can be set, and several uprights 2 and multiple adjusting mechanisms can protect multiple sides of the scaffolding body 1.

[0026] Reference Figure 1-3The guardrail 21 is threaded on the outer wall of the threaded rod 31. People can drive the guardrail 21 to move up and down by rotating the threaded rod 31 and cooperating with the vertical rod 2 to limit the guardrail 21.

[0027] Reference Figure 1-3 A crank 36 for driving the threaded rod 31 to rotate is provided on one side of the base 3. A transmission mechanism is provided between the threaded rod 31 and the crank 36. The transmission mechanism includes a first bevel gear 33 fixed to the outer wall of the threaded rod 31, a second bevel gear 34 meshingly connected to one side of the first bevel gear 33, and a rotating rod 35 fixed in the second bevel gear 34. The crank 36 is fixed at one end of the rotating rod 35 away from the second bevel gear 34. The first bevel gear 33 and the second bevel gear 34 are both located inside the base 3.

[0028] When people shake the crank 36, the rotating rod 35 and the second bevel gear 34 are driven to rotate. When the second bevel gear 34 rotates, the meshed first bevel gear 33 is driven to rotate. When the first bevel gear 33 rotates, the threaded rod 31 is driven to rotate.

[0029] Reference Figure 1-3 A ring 37 is fixedly provided on the outer wall of the rotating rod 35, and the ring 37 is rotatably connected in the base 3. The ring 37 can connect the rotating rod 35 and the base 3, so that the rotating rod 35 can rotate on the base 3 without detaching.

[0030] Reference Figure 1-2 A protective mechanism is provided at the top of the threaded rod 31. The protective mechanism includes a nut 4 threadedly arranged at the top of the threaded rod 31, and a soft component 41 fixedly arranged at the top of the outer wall of the nut 4. The protective mechanism can be installed at the top of the threaded rod 31 through the nut 4 thread. The soft component 41 is made of rubber, silicone and other materials with certain elasticity and softness. When people accidentally touch the top of the threaded rod 31 during construction, people can be buffered and protected, so that people are not easily injured.

[0031] The implementation principle of the guardrail structure of a scaffold in the embodiment of the utility model is:

[0032] When people need to adjust the height of the guardrail, they can shake the crank 36 to drive the rotating rod 35 and the second bevel gear 34 to rotate. The second bevel gear 34 rotates to drive the meshing first bevel gear 33 to rotate. The first bevel gear 33 rotates to drive the threaded rod 31 to rotate. The threaded rod 31 rotates to cooperate with the vertical rod 2 to limit the guardrail 21, and can drive the guardrail 21, the protection net 23 and the ring 22 to move up and down as a whole, so as to adjust the protection height of the guardrail;

[0033] When people accidentally touch the top of the threaded rod 31 during construction, the soft part 41 will provide buffer protection for people, making it less likely for people to get hurt. People can rotate the nut 4 to remove the protection mechanism from the top of the threaded rod 31 as a whole, and then continue to raise the guardrail. When the guardrail 21 is detached from the top of the threaded rod 31, people can remove the guardrail 21, the protection net 23 and the ring 22 as a whole from the scaffold body 1 for maintenance and replacement.

[0034] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
