Abstract

The climbing steel wire rope is an important part of an engineering structure, and the climbing rope needs to be fixed through a turnbuckle during installation. The prior spiral buckle has two types of closed and opened buckles, wherein the former has complex operation and the latter has potential safety hazard. The invention comprises a rod body, a closed ring, an open ring, a pre-tightening thread, a lock catch pin shaft and a spring buckle head; the spring buckle head is fixed at the opening of the split ring through a lock catch pin shaft, and the climbing rope can enter or be taken out of the split ring through pressing the spring buckle head. The invention has the advantages that: compared with the prior full-closed climbing rope turnbuckle, the climbing rope clamp is fixed when leaving a factory, the rope clamp is not required to be fixed during installation, and the rope clamp is not required to be loosened during disassembly; compared with the opening climbing rope turnbuckle, the spring buckle head ensures that the climbing rope cannot fall off from the opening ring during working, thereby not only improving the working efficiency of installation and disassembly, but also ensuring the safety during working.

Description

Anti-drop turnbuckle

Technical Field

The invention belongs to the technical field of construction machinery, relates to operating equipment for buildings, and particularly relates to an anti-falling turnbuckle.

Background

The turnbuckle has wide application range, and can be applied to industries of engineering, factories, transportation and the like with various sizes from families. The former spiral buckle has two types of closed and opened buckles, the former has complex operation, and the latter has potential safety hazard when in use. Therefore, the research and development of a novel anti-falling screw fastener have important significance.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides an anti-falling turnbuckle for engineering projects.

According to the technical scheme provided by the invention: the anti-falling screw fastener comprises a rod body, a closed ring, an open ring, a pre-tightening thread, a lock catch pin shaft and a spring fastener head; the rod body is a long annular rod piece, the end heads of the closed ring and the open ring are provided with the pre-tightening threads, and the closed ring and the open ring are connected to the rod body through the pre-tightening threads; the spring buckle head is fixed at the opening of the split ring through a lock catch pin shaft, and the climbing rope can enter or be taken out of the split ring through pressing the spring buckle head.

The invention has the advantages that: compared with the prior full-closed climbing rope turnbuckle, the climbing rope clamp is fixed when leaving a factory, the rope clamp is not required to be fixed during installation, and the rope clamp is not required to be loosened during disassembly; compared with the opening climbing rope turnbuckle, the spring buckle head ensures that the climbing rope cannot fall off from the opening ring during working, thereby not only greatly improving the working efficiency of installation and disassembly, but also ensuring the safety during working.

Description of reference numerals: 1-rod body, 2-closed ring, 3-split ring, 4-pre-tightening thread, 5-locking pin shaft and 6-spring buckle head.

Detailed Description

The invention is further illustrated by the following specific figures and examples.

As shown in fig. 1: the invention mainly comprises a rod body 1, a closed ring 2, an open ring 3, a pre-tightening thread 4, a lock catch pin shaft 5 and a spring buckle head 6; the rod body 1 is a long annular rod piece, the end heads of the closed ring 2 and the open ring 3 are provided with the pre-tightening threads 4, and the closed ring 2 and the open ring 3 are connected to the rod body 1 through the pre-tightening threads 4; the spring buckle head 6 is fixed at the opening of the split ring 3 through a lock catch pin shaft 5, and the climbing rope can enter or be taken out of the split ring 3 by pressing the spring buckle head 6.

In particular, the application is as shown in fig. 1. When the climbing rope is installed, one end of the climbing rope is sleeved on the closed ring 2 to be fixed, the other end of the climbing rope enters the open ring 3 by pressing the spring buckle head 6, the climbing rope is fastened by rotating the pre-tightening thread 4, and the pre-tightening force can be adjusted to enable the climbing rope to meet the fastening requirement; when the device is disassembled, the pre-tightening threads 4 are rotated reversely to loosen the climbing rope, and the climbing rope is taken out of the split ring 3 by pressing the spring buckle head 6 to complete the disassembly.
