Description

Pulley convenient to install fast Technical Field The application relates to the technical field of vehicle rescue, in particular to a pulley convenient to install quickly. Background When a vehicle fails and cannot run by itself, it is often necessary to transport it to a repair site by means of a rescue vehicle. At present, a common rescue mode is to connect a rescue vehicle with a fault vehicle by using a pulley and a trailer shackle. The existing pulley for vehicle rescue connection has one end which is a pulley body for connecting a fault vehicle, and one end far away from the pulley body forms a connecting ring for connecting a trailer shackle or a rope. This construction has the problem that, in practice, the pulley is not removable and the trailer shackle or rope must be passed through the coupling ring when the trailer shackle or rope is to be coupled. In an actual rescue scene, the condition that the connection state needs to be adjusted possibly happens, at the moment, the trailer needs to be opened or the rope is untied to be adjusted according to the existing pulley structure, and the operation mode is inconvenient, the operation difficulty of rescue workers is increased, and the operation process is time-consuming. Disclosure of utility model In order to solve the technical problems, the application provides a pulley convenient to install quickly, which comprises a pulley body, a pulley shaft, a first connecting cover body and a second connecting cover body; The first connecting cover body and the second connecting cover body are respectively covered on two sides of the wheel body; The wheel axle sequentially passes through the centers of the first connecting cover body, the wheel body and the second connecting cover body; the first connecting cover body comprises a first cover part and a first hook part which are integrally formed; The second connecting cover body comprises a second cover part and a second hook part which are integrally formed; the first hook part and the second hook part are enclosed together to form a connecting ring for connecting a trailer shackle or a rope; The first connecting cover body and the second connecting cover body are detachably connected. In some embodiments of the present application, a first clamping groove is formed on an end surface of the first hook portion, which is close to the second hook portion, a first clamping block is formed on an end surface of the second hook portion, which is close to the first hook portion, and when the first connecting cover body and the second connecting cover body are both covered on two sides of the wheel body, the first clamping block is clamped in the first clamping groove. In some embodiments of the present application, a second clamping block is formed on an end surface of the first hook portion, which is close to the second hook portion, a second clamping groove is formed on an end surface of the second hook portion, which is close to the first hook portion, and when the first connecting cover body and the second connecting cover body are both covered on two sides of the wheel body, the second clamping block is clamped in the second clamping groove. In some embodiments of the present application, a first reinforcing portion is formed at a connection portion between the first cover portion and the first hook portion. In some embodiments of the present application, a second reinforcing portion is formed at a connection portion between the second cover portion and the second hook portion. In some embodiments of the present application, the opening directions of the first hook portion and the second hook portion are away from each other. Compared with the prior art, the pulley convenient to install quickly has the advantages that the pulley convenient to install quickly comprises a pulley body, a pulley shaft, a first connecting cover body and a second connecting cover body; the first connecting cover body and the second connecting cover body are respectively arranged on two sides of the wheel body in a covering mode, the wheel shaft sequentially penetrates through the first connecting cover body, the wheel body and the center of the second connecting cover body, the first connecting cover body comprises a first cover portion and a first hook portion which are integrally formed, the second connecting cover body comprises a second cover portion and a second hook portion which are integrally formed, the first hook portion and the second hook portion are jointly enclosed to form a connecting ring for connecting a trailer shackle or a rope, the first connecting cover body and the second connecting cover body are detachably connected, and therefore when a connecting state needs to be adjusted, the first connecting cover body or the second connecting cover body can be opened, the first connecting cover body and the second connecting cover body can be separated, the first hook portion and the second hook portion can be separate
