Detailed Description

The technical solution of the present invention will be further described with reference to the accompanying drawings.

An auxiliary assembly tool for a bayonet socket of a fuel filler box comprises a sleeve 10, a pipe orifice at the front end of the sleeve 10 is provided with a linear convex strip at the end face of a pin hole 2 on a bayonet socket 1 or a concave part which is matched with a side surface in a parallel axial direction on a molded surface in a clamping and sticking way, and the rear end of the sleeve 10 is provided with a handle 20. According to the different shapes of the end face of the bayonet socket 1, sleeves with different shapes can be manufactured, and the manufacturing method can be divided into two types:

when the end surface of the pin hole 2 of the bayonet holder 1 is provided with a straight convex strip, the concave part is a U-shaped or n-shaped notch 11 arranged on the pipe wall at the end surface of the sleeve 10, and at least two notches 11 are arranged in the circumferential direction, and the connecting line of the two notches passes through the pipe core. The gaps 11 are arranged at intervals of 4-6 in the circumferential direction. During assembly, the linear convex strip on the end face of the pin hole of the pin base is clamped in the notch 11, so that the auxiliary tool can be fixed at the position on the pin base, and then the auxiliary tool is pressed in and rotates to realize assembly operation.

When the end surface of the pin hole of the bayonet holder 1 is in a waist shape with parallel lateral planes in two axial directions, the section of the inner tube cavity of the sleeve 10 close to the tube end is a waist-shaped hole, and the waist-shaped hole comprises two straight hole walls which are parallel to each other.

Preferably, the handle 20 is arranged on the tail rod 30, and a transition rod 40 is arranged between the tail rod 30 and the sleeve 10 and arranged in the same core; the rod diameter of the transition rod 40 is smaller than the rod diameters of the tail rod 30 and the sleeve 10 at the two ends. The auxiliary tool materials are properly reduced under the condition of ensuring the service performance of the auxiliary tool, so that the cost is reduced, the structure is more reasonable, the weight is lighter, and the use is more convenient.

Further, the handle 20 is vertically arranged with the tail rod 30 and forms a small clearance type movable fit with the through hole of the tail rod 30. That is, the handle 20 can be pulled out a small amount of the through hole of the tail rod 30, which is more convenient to operate in the limited deployment space of the filler neck box.
