This patent document relates to rope guide equipment and, in particular, to a plug-in rope guide protective shell.
Automobile winches are mainly used for off-road vehicles, agricultural vehicles, ATV sport vehicles, yachts, and other special vehicles. They are self-protection and traction devices for vehicles and ships. The automobile winch has a rope guide for guiding and winding a strand rope onto a reel or a drum. In the related art, a protective shell is mounted on the rope guide through a bolt connection or adhesive connection to protect the rope guide. However, the adhesive connection has poor stability, which tends to cause the protective shell to fall off, and the bolt connection has the problem of inconvenient mounting and detachment of the protective shell.
In some aspects, a plug-in rope guide protective shell, according to embodiments of the present technology, includes a shell body having an inner cavity for accommodating a rope guide, the rope guide having a guide opening penetrating the rope guide in a first direction, and a plug-in member connected to the shell body and arranged in the inner cavity of the shell body, the plug-in member being configured to be inserted in the guide opening.
The subject matter described in this patent document can be implemented in specific ways that provide one or more of the following features.
Embodiments of the present technology are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below, by referring to the accompanying drawings, are exemplary and are intended to explain the present technology but cannot be interpreted as limitations to the present technology.
Hereinafter, referring to

In other embodiments, the wall surface defining the guide opening may be provided with two abutting parts extending in the up-down direction, and the two abutting parts are spaced apart in the up-down direction. An upper end face of the abutting part located below is the second abutting surface, and a lower end face of the abutting part located above is the first abutting surface.
The plug-in member 3 includes a first plug-in part 31 and a second plug-in part 32 spaced apart in the second direction. The first plug-in part 31 and the second plug-in part 32 can move relative to each other to provide a movable position and a connection position. In the connection position, the first abutting surface 22 abuts against the first plug-in part 31, and the second abutting surface 23 abuts against the second plug-in part 32. In the movable position, the first abutting surface 22 is separated from the first plug-in part 31, and the second abutting surface 23 is separated from the second plug-in part 32.
Specifically, as shown in
In the connection position, the first abutting surface 22 abuts against the first plug-in part 31 and the second abutting surface 23 abuts against the second plug-in part 32 so that the first plug-in part 31 and the second plug-in part 32 are inserted in the guide opening 21 and the plug-in member 3 will not come out of the guide opening 21 due to the friction between the first abutting surface 22 and the first plug-in part 31 and the friction between the second abutting surface 23 and the second plug-in part 32.
In the movable position, the first abutting surface 22 is separated from the first plug-in part 31, and the second abutting surface 23 is separated from the second plug-in part 32 so that the first plug-in part 31 and the second plug-in part 32 can be inserted into or detached from the guide opening 21 in the front-rear direction.
It may be understood that the first plug-in part and the second plug-in part are not limited to the shape of a sheet, and in other embodiments, the first plug-in part and the second plug-in part are rod-shaped.
In some embodiments, the first plug-in part 31 has a first engaging portion 311 at an end in the first direction, and the second plug-in part 32 has a second engaging portion 321 at an end in the first direction.
