The purpose is to provide a fuel tank. [Structure] A resin fuel tank with a clip, characterized in that a fixing clip 5 for fixing a hose, a harness or the like formed at the time of molding the resin fuel tank 1 is integrally provided so as to project from the tank surface. tank.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resin fuel tank with a clip in which a clip for fixing a hose or a harness attached to a fuel tank is integrally formed with a fuel tank.

[0002]

[Prior art]

 In order to fix a piping hose, a harness and the like to a fuel tank of an automobile or the like, a fixing clip A is attached to the top surface of the fuel tank B as shown in FIG. The fixing clip A has a cylindrical shape formed by injection molding or the like, and is composed of a pair of holding portions D having an insertion portion C opened at the top and a base portion E thereof. When the clip A is attached to the fuel tank B made of resin, the lower surface of the base E is welded and fixed by hot plate welding F or the like.

[0003]

[Problems to be solved by the device]

 However, since the conventional fixing clip A as described above needs to be manufactured separately from the fuel tank B made of resin, and the work of welding and fixing the same to the fuel tank B is also required, the productivity is low and There was a problem that it would lead to higher costs.

[0004]

[Means for solving problems]

 The present invention was made in order to solve the above-mentioned conventional problems. By separately molding a fixing clip at the time of molding a resin fuel tank, a separate clip manufacturing process and a clip welding process are performed. The purpose of the present invention is to provide a product that can be manufactured at a low price by omitting the above.The main point is to provide a resin fuel tank with a clip for fixing a hose, harness, etc. It is a resin fuel tank with a clip, which is integrally provided so as to project from the tank surface.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a perspective view of a resin fuel tank with a clip according to the present invention, FIG. 2 is an enlarged cross-sectional view of an essential part of FIG. 1, FIG. 3 is an explanatory view of the first manufacturing process of the clip portion, and FIG. 5 is a vertical sectional view showing another embodiment of the clip, FIG. 6 is a vertical sectional view showing a clip of still another embodiment, and FIG. 7 is a resin fuel tank with a clip. It is a perspective view of other examples.

In the figure, reference numeral 1 is a resin fuel tank, a pipe 3 is attached to an upper wall surface 2 of the resin tank in an upright state, and a tip portion of the fuel tank is bent in parallel with the upper wall surface 2. A hose 4 such as an inlet or an outlet is connected to the tip portion. Numeral 5 is a fixing clip for sandwiching and fixing the hose 4, which has a pair of elastic forces in the upper wall surface 2 of the resin fuel tank 1 having a cylindrical shape protruding from the surface and having the insertion portion 6 opened at the upper portion. It is composed of the holding portions 7, 7, and is integrally formed with the fuel tank 1.

Next, the production of the fixing clip 5 will be described with reference to FIGS. 3 and 4. At the time of blow molding of the resin fuel tank 1, the fixing clip is attached to the upper surface of the upper wall surface 2. The solid solid portion 8 of the clip, which is almost the same as the outer shape of 5, is projected and simultaneously molded. At this time, if the clip solid portion 8 is set so as to be located at the seam of the mold, a burr 9 is formed on the clip solid portion 8 along the dividing line of the mold. Then, after the blow molding, the burr 9 is scraped off. At this time, the solid clip portion 8 is simultaneously processed into the same shape as the fixing clip 5, and the fixing clip 5 is formed integrally with the tank. The fuel manufacturing tank 1 is formed.

FIG. 5 shows an embodiment in which two fixing clips 5 are formed side by side, and FIG. 6 shows a fixing clip in which a circular hole 10 for inserting the hose 4 is formed. 5 is another embodiment. Incidentally, FIG. 7 shows an embodiment in which the fixing clip 5 is provided on the side wall surface 11 of the resin fuel tank 1. Other points of the embodiment shown in FIGS. Is the same as.

In addition to the case where the fixing clip 5 is formed at the same time as the burr 9 is scraped off after the blow molding of the fuel tank 1 as described above, when the fixing clip 5 has a simple shape. Can be formed simultaneously with blow molding of the fuel tank 1.

[0010]

[Effect of device]

 As described above, in the resin fuel tank with a clip according to the present invention, a fixing clip such as a hose or a harness formed at the time of molding the resin fuel tank is protruded from the tank surface and integrally formed with the resin fuel tank. Since the configuration is provided, the number of parts and the manufacturing process can be reduced. Therefore, there are various effects that the productivity is improved and the product can be provided at a low price.
