Benefits of technology

The adjustable tie-down ratchet has several advantages. First, it has an adjusting buckle made up of an adjustable base and a positional base. This allows for easy adjustment of the mainframe's position based on different using conditions. Second, the ratchet has a movable shaft and a fixed shaft that connect the binding strap to the mainframe. This allows for easy winding and interlacing of the binding strap on the shafts. Lastly, the ratchet is simple and practical, making it convenient to operate and adjust the mainframe's position.

Problems solved by technology

Because practical service environments and situations are different, if the position of the mainframe just intervenes with other article, the binding operation is inconvenient, even the mainframe or the goods are instable, and certain potential safety hazards exist, e.g., the goods easily drop, or the mainframe is loosened so that the binding strap is loosened and released, etc.

embodiment 1

[0023]As shown in FIGS. 1-8, an adjustable tie-down ratchet in this Embodiment comprises a mainframe 1 and a binding strap 2 installed on the mainframe 1, wherein the mainframe 1 comprises an adjusting buckle 4 composed of the adjustable base 4a and the positional base 4b connected with the adjustable base 4a, a handle 12 movably attached to the adjustable base 4a and a transmission mechanism disposed in the adjustable base 4a and activated by the handle 12 and can prevent reversing.

[0024]In this embodiment, the adjustable base 4a is connected with the positional base 4b by a screw 46 and a nut 47, of course, the screw 46 and the nut 47 can also be replaced by a rivet shaft. The adjustable base 4a can be connected with the positional base 4b by other means.

[0025]The adjustable base 4a and the positional base 4b are respectively provided with a left sheet and a right sheet which are arranged symmetrically, the two front-back corresponding left sheets in the adjustable base 4a and the...

embodiment 2

[0032]As shown in FIG. 9, in this embodiment, the binding strap is divided into two sections, which are respectively a tensioning strap 16 and an adjusting strap 17. A hook 3 is respectively fixed at the outer end of the tensioning strap 16 and the outer end of the adjusting strap 17, the inner end of the tensioning strap 16 is a free end and is connected to the main rotating shaft 8, and the inner end of the adjusting strap 17 is a free end and is connected to the movable shaft 6 and the fixed shaft 5. During adjustment, the adjusting strap 17 can be adjusted in the arrow direction of the figure, and its adjusting method is same as the binding strap adjusting method in Embodiment 1. In addition, the tensioning operation of the tensioning strap 16 is same as that of the binding strap in Embodiment 1, and thus is not described herein.

[0033]Described above are merely preferred embodiments of the present invention. It should be noted that many modifications or improvements may be made ...

Abstract

An adjustable tie-down ratchet includes a mainframe and a binding strap, wherein the mainframe includes an adjusting buckle, a handle and a transmission mechanism; a fixed shaft and a movable shaft are arranged on the rear part of the adjusting buckle for connecting the binding strap; an adjusting groove is formed at the rear part of the adjusting buckle; each adjusting groove defines a locking position and a adjusting position; the movable shaft can movably sliding in the adjusting grooves, and the fixed shaft is fixed below the adjusting grooves. In the present invention, the binding strap is movably connected with the mainframe, so that the position of the mainframe can be adjusted according to needs under different usage conditions, the operation is convenient, and the overall device is simple and practical.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a tie-down ratchet used in an automobile, a truck, a trailer or a motorcycle for conveniently binding and fixing goods.BACKGROUND OF THE INVENTION[0002]The conventional tie-down ratchet is composed of a tensioning device mainframe, a long binding strap, a short binding strap and the like. The mainframe adopts the anti-reverse ratchet wheel mechanism principle, a handle directly drives a driving pawl, the driving pawl pushes ratchet wheels, the ratchet wheels directly drive a main rotating shaft, the binding strap wound around the main rotating shaft is thus tensioned, a locking pawl prevents the ratchet wheels from reversing, and certain tension can be kept on the binding strap to bind and fix goods. In addition, one end of the long binding strap in the existing tie-down ratchet is provided with a hook, and the other end is a free end and penetrates through the mainframe in operation; one end of the short binding strap is ...
