scaffolding protection device

Abstract

This invention relates to a scaffolding safety device for installation on a scaffold. The scaffold has a plurality of straight bars and a plurality of crossbars, with each crossbar connected at both ends to two of the straight bars. Each crossbar includes a first crossbar and a second crossbar. The scaffolding safety device has a guardrail body and a telescopic device. The guardrail body has a base bar located at the bottom of the guardrail body. The base bar has a fixed end and an extending end, with the fixed end detachably mounted on the first crossbar. The telescopic device protrudes along the length of the base bar from the extending end, and a locking portion of the telescopic device is detachably mounted on the second crossbar of the scaffold. By incorporating the telescopic device, the overall length of the scaffolding safety device is adjustable, adapting to scaffolds of different sizes and increasing its practicality.

Claims

1. A scaffolding protection device for mounting on a scaffold; the scaffolding having a plurality of straight bars and a plurality of crossbars; each crossbar having its two ends connected to two of the straight bars, the crossbars including a first crossbar and a second crossbar; the scaffolding protection device comprising: a guardrail body having: a base bar disposed at the bottom of the guardrail body; the base bar having: a fixed end and an extension end, the fixed end and the extension end being opposite ends of the base bar, and the fixed end being detachably mounted on the first crossbar; a telescopic device protruding from the extension end of the base bar and movably along the length direction of the base bar, and the telescopic device having: a connecting portion movably disposed from the extension end of the base bar and along the length direction of the base bar; a locking portion connected to the connecting portion and protruding from the base bar, and detachably mounted on the second crossbar of the scaffolding.

2. The scaffolding protection device as claimed in claim 1, wherein the connecting portion is movably inserted through the extension end of the base pole; and the locking portion is used to detachably lock the second crossbar of the scaffolding.

3. The scaffolding protection device as described in claim 1 or 2, wherein the locking part has a front sidewall and a rear sidewall, the front sidewall and the rear sidewall being spaced apart along a width direction that is not parallel to the length direction of the base rod; the front sidewall and the rear sidewall are used to clamp one of the straight rods.

4. The scaffolding protection device as described in claim 1 or 2, wherein a locking groove is recessed on the side of the locking portion away from the extension end; the telescopic device has a protrusion disposed at the opening of the locking groove and extending downward to partially cover the opening of the locking groove; the protrusion and a bottom groove wall of the locking groove are used to clamp the second crossbar.

5. The scaffolding protection device as claimed in claim 3, wherein a locking groove is recessed on one side of the front sidewall away from the extension end; the telescopic device has a protrusion disposed at the opening of the locking groove and extending downward to partially cover the opening of the locking groove; the protrusion and a bottom groove wall of the locking groove are used to clamp the second crossbar.

6. The scaffolding protection device as claimed in claim 1 or 2, wherein the guardrail body has a hook portion disposed at the fixed end of the base bar and used to hang on the first crossbar of the scaffolding.

7. The scaffolding protection device as claimed in claim 6, wherein the telescopic device has a limiting portion that is spaced apart from the locking portion along a width direction that is not parallel to the length direction, and the limiting portion and the locking portion together form a hook limiting groove; when the locking portion of the scaffolding protection device is disposed on the second crossbar, and the hook of another scaffolding protection device is hung on the second crossbar, the hook of the other scaffolding protection device is located in the hook limiting groove of the scaffolding protection device.

8. The scaffolding protection device as claimed in claim 1 or 2, wherein the base pole has a base pole fitting portion disposed at the extended end of the base pole; the telescopic device has a telescopic fitting groove recessed into the surface of the telescopic device and extending along the length direction of the base pole; wherein, The bottom rod fitting part can be slidably inserted into the telescopic fitting groove.

9. The scaffolding protection device as claimed in claim 8, wherein the telescopic fitting groove has an abutment groove wall located at one end of the telescopic fitting groove near the base rod and abutting against the base rod fitting portion to restrict the telescopic device from moving away from the base rod.

10. The scaffolding protection device as described in claim 1 or 2, having a fixing member that passes through the base pole and abuts against the telescopic device to restrict relative movement between the telescopic device and the base pole.
