Description

Technical Field

[0001] The utility model relates to the field of construction equipment, in particular to a foldable scaffolding. Background Technique

[0002] The scaffolding is one of the auxiliary tools that must be applied in the ship repair industry construction operation, providing strong support for construction safety and operation efficiency. Under normal circumstances, when constructing and operating in the shipbuilding industry, traditional steel pipe scaffolding is used. In order to strengthen the protection, the guardrail is fixed, and the disassembly and assembly workload is large, making the scaffolding not easy to disassemble, store, and not conducive to the use of special painting in the cabin. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a foldable scaffolding to solve the current pain points in this field.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A foldable scaffolding includes a support arm. The support arm is fixed through an ear plate. A wooden board is fixedly installed on the support arm. A guardrail column is hinged on the outer side of the support arm. A fixed stop block is fixedly installed on the support arm below the guardrail column. The fixed stop block can block the lower end of the guardrail column to prevent the guardrail column from turning outwards. A movable plate is vertically slidably installed below the fixed stop block. A return spring is arranged on the movable plate. A retaining pile is fixedly installed at the outer end of the movable plate. The retaining pile can block the lower end of the guardrail column so that the upper part thereof will not fold inwards.

[0006] Further explanation, a lifting block is vertically slidably installed at the inner end of the support arm. A handle is hinged on the lifting block. A lifting hook is fixedly installed at the end of the handle. A lever is hinged in the middle of the support arm. The middle of the lever is hinged, and the two ends are respectively close to the movable plate and the lifting hook. When the handle rotates, the lever can be lifted by the lifting hook, so that the other end of the lever presses down.

[0007] Further explanation, a limiting groove is fixedly installed in the support arm below the lifting block. The lifting hook can be inserted into the limiting groove.

[0008] To sum up, the beneficial effect of the utility model compared with the prior art is that in the utility model, the scaffolding guardrail is of a foldable design. In the unfolded state, the lower end of the guardrail column is locked by the fixed stop block and the retaining pile, and can provide sufficient safety protection. As long as the handle is pulled, the guardrail column can be unlocked and folded inwards. At the same time, the handle is designed with a self-locking mechanism, and only when the handle is pulled up can it be turned, preventing accidental touch and causing danger. Description of the Drawings

[0009] By reading the following detailed description with reference to the accompanying drawings, the above and other objects, features, and advantages of the exemplary embodiments of the present utility model will become readily understood. In the drawings, several embodiments of the present utility model are shown in an exemplary rather than restrictive manner, wherein:

[0011] Explanation of reference numerals: 10, support arm; 11, ear plate; 12, guardrail; 13, fixed stop; 14, movable plate; 15, retaining pile; 16, return spring; 17, lever; 18, lifting block; 19, handle; 20, lifting hook; 21, limiting groove. Detailed implementation manners

[0012] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0013] A foldable scaffolding includes a support arm 10, the support arm 10 is fixed through an ear plate 11, a wooden board is fixedly installed on the support arm, a guardrail column 12 is hinged outside the support arm 10, a fixed stop 13 is fixedly installed on the support arm 10 below the guardrail column 12, the fixed stop 13 can block the lower end of the guardrail column 12 to prevent the guardrail column 12 from turning outwards, a movable plate 14 is vertically slidably installed on the lower side of the fixed stop 13, a return spring 16 is arranged on the movable plate 14, a retaining pile 15 is fixedly installed at the outer end of the movable plate 14, and the retaining pile 15 can block the lower end of the guardrail column 12 so that the upper part thereof will not fold inwards.

[0014] A lifting block 18 is vertically slidably installed at the inner end of the support arm 10, a handle 19 is hinged on the lifting block 18, a lifting hook 20 is fixedly installed at the end of the handle 19, a lever 17 is hinged in the middle of the support arm 10, the middle of the lever 17 is hinged, and the two ends are respectively close to the movable plate 14 and the lifting hook 20. When the handle 19 rotates, the lever 17 can be lifted by the lifting hook 20, so that the other end of the lever 17 presses down to press down the movable plate 14, so that the guardrail column 12 can be folded.
