The present invention relates to a hook of a fuel filler lock which is mounted on a side outer-panel inside a fuel filler door of a vehicle body, in particular a fuel. The hook structure of an automobile fuel filler lock is adapted to enhance the durability of the fuel filler lock by changing the structure of the hook fitted into the filler lock.

In general, the vehicle is composed of a chassis, which forms the main part of the vehicle, such as an engine, a power transmission device, and a suspension, and a vehicle body which not only surrounds each of the above-described components but also supports and forms the exterior of the vehicle.

In the vehicle body, as shown in FIG. 1, a main panel constituting the rear corner portion of the vehicle body is called a quarter panel 10, and a fuel having a predetermined shape is formed at one side of the quarter panel 10. The filler door 11 is provided, and there is a side out panel 12 therein, and the fuel filler lock 13 is attached thereto.

Here, the fuel filler lock to be mounted on the side-out panel is fixed to the hook and the spring inside the fuel filler lock by a pin, so that when the fuel filler door is opened, the cable connected to the hook tip of the fuel filler lock ( It is opened by the operation of the hook by the pull of (not shown), and when closed, the hook is fitted into the locking groove of the fuel filler door by the elastic force of the spring.

The hook structure of the vehicle fuel filler lock according to the related art has a hollow rectangular housing 21, as shown in FIG. 3, and the housing 21 has a hook 22 having an H-shaped cross section. In the hook 22, there is a spring 23 for operating the hook 22, and the hook 22 and the spring 23 are horizontally disposed by the pin 24 in the form of a thin rod. It is a structure that is fastened and fixed to 21.

In the conventional fuel filler lock having the above structure, the hook 22 and the spring 23 and the hook 22 and the spring 23 are coupled to the housing 21 in the horizontal direction by the pin 24. Since the assembly of the fuel filler lock is difficult because the housing 21 is located on the same line, it is difficult to assemble the fuel filler lock, and the structure fastened by the pin 24 as described above has the durability of the fuel filler lock due to the vibration of the vehicle. There is a structural problem that the pin 24 is removed by weakening.

Accordingly, the present invention has been made in order to solve the above problems, by modifying the hook structure of the fuel filler lock to remove the fastening by the pin and insert the hook directly into the housing, thereby assembling the fuel filler lock The object is to provide a hook for an automobile fuel filler lock that is made simple.

The present invention for achieving the above object, there is a hollow rectangular housing in the fuel filler lock, each of the inner side of the inner side of the housing is formed with a fitting groove, the housing has a Y-shaped cross section The hook has a built-in, and each of the protrusions are formed at both ends around the central portion of the hook, the double portion of the spring is fitted through the hook, respectively, the hook and the spring formed integrally with each other The protrusion is fixedly seated by being forcibly inserted into the fitting groove of the housing.

Therefore, the hook structure inserted into the housing of the fuel filler lock has a structure in which the spring and the hook are integrally inserted into the housing in the vertical direction without fastening by a pin, thereby simplifying the assembly of the fuel filler lock and enhancing durability. It is to be made.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

2 is a cross-sectional view showing the hook structure of the vehicle fuel filler lock according to the present invention, the fuel filler lock has a hollow rectangular housing (1), each of the fitting grooves in the middle of the inner side of both sides of the housing (1) (1a) is formed, the housing (1) is provided with hooks (2) formed with projections (2a) at both ends of the center around the central portion, respectively, and double spring (3) on the projection (2a) The hooks 2 and the springs 3 which are respectively fitted through the hooks 2, and the hooks 2 and the springs 3 integrally formed with each other are forcibly fitted into the fitting grooves 1a of the housing 1. It is designed to be fixed and seated.

In the hook structure of the fuel filler lock as described above, the material of the housing (1) in order to easily fit the projection (2a) formed in the center portion of the hook (2) to the fitting groove (1a) formed in the housing (1) Molded with elastic vinyl chloride (PVC), the hook formed with the protrusions should be made of a material of hard plastics.

In addition, the double structure of the spring (3) is the elastic force is reinforced to facilitate the operation of the hook (2), and the c-shaped connecting portion of the spring (3) is mediated through the central portion of the hook (2) It will be mounted to the bar, it will be preferable to form a groove in the center portion of the hook (2) to be fixed in the state the c-shaped connecting portion of the spring 3 is fitted.

As described above, the hook structure of the vehicle fuel filler lock according to the present invention is formed in a form in which the shape of the hook is directly inserted into the housing integrally with the spring, thereby eliminating the structure that is fastened by the pins. Easy to assemble, the durability of the hook is to increase the effect.
