Description

TECHNICAL FIELD

The utility model relates to a tensioning device for fastening and fixing cargo in a vehicle, a trailer, an airplane, a ship and another means of transport, in particular a lashing hook for a tensioning device that is secured against loosening and a vehicle safety tensioning device with such a lashing hook.

STATE OF THE ART

A vehicle safety tensioner usually consists of, among other things, a tensioner main device, a long lashing strap and a short lashing strap. The main device often uses the principle of a ratchet mechanism, which prevents reverse rotation. A driving pawl is driven directly by means of a handle and a ratchet wheel is pushed through the driving pawl, which directly drives a main rotating shaft, thereby tensioning a lashing strap wound on the main rotating shaft. A brake pawl prevents the ratchet wheel from rotating backwards, allowing a specific tension to be maintained on the lashing strap to secure cargo. A lashing hook is connected to one end of the long and short lashing straps and is connected to a corresponding anchor point of a vehicle or other means of transport. While driving a vehicle, vibration or bumping is inevitable, especially on routes with poor road conditions. In a conventional tensioning device, a lashing hook is directly connected to a corresponding anchor point of a vehicle and constant swinging and bumping generates strong shocks that act directly on the lashing hook and could exceed the load-bearing capacity of the lashing hook, so that there is a risk of the lashing hook breaking. Furthermore, constant swinging and bumping could cause the tension on the lashing strap to gradually decrease and even the lashing strap to detach from the main device, so that there is insufficient lashing force available for cargo and a shift occurs. Therefore, there is a major security risk. As stated above, an improvement to an existing vehicle safety tensioner is desired.

DETAILED DESCRIPTION

The utility model will be discussed in more detail below with reference to the accompanying drawings using specific exemplary embodiments.

First embodiment:

How out 1 until 3 results, the lashing hook secured against loosening for a tensioning device according to the present exemplary embodiment comprises a lashing hook body and a hook 2 provided on the lashing hook body. The hook 2 and the lashing hook body are designed to be split and the hook 2 is removably connected to the lashing hook body. The lashing hook body includes a U-shaped connecting ring 11 and a connecting rod. The connecting rod is mounted on the opening side of the U-shaped connecting ring 11 and thus forms a closed connecting ring together with the U-shaped connecting ring 11. As the connecting rod in the present embodiment, a bolt 12 which passes through opposite side walls of the opening side of the U-shaped connecting ring 11 and is connected and fixed via a nut 13 is used.
