Abstract

PURPOSE:To facilitate the furnishing of a belt member and check simply the condition of fitting, by providing the turning movement regulating claw portions of the belt member at such a location where the belt member can make a turning movement in the regular belt member fitting direction only when a fixing pin has been completely inserted. CONSTITUTION:Such belt member 20 turning movement regulating claw portions 23 as to protrude in the belt member 20 width direction and become wider than the interval between bracket plates 22, are provided in the vicinity of a fixing pin 21 winding around portion 20a at one end of the member 20, and arrangement is made so that the member 20 may be turned in the regular fitting direction (B direction) from the insertion direction (A direction) only when the pin 21 is in the condition of having been completely inserted. At the time of the pin 21 having been incompletely inserted, the member 20 claw portions 23 get caught at the bracket plates 22 to make a detour, so the opposite side end portion of the belt member does not reach a car body fitting bracket 24, and the pin 21 being in the condition of having been incompletely inserted is recognized easily.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a fuel tank mounting structure.

<Prior art> As a conventional fuel tank mounting structure, for example,
There are some as shown in Fig. 9 and Fig. 9.
(Refer to Publication No.-93521).

■ is the fixing pin, and there are heads 1 on both ends to prevent it from falling off.
It has a. And 2 is a fixed bracket,
It has a pair of opposing left and right bracket plates 3.4. These left and right bracket plates 3.4 have horizontal notches 3a, 4a for inserting the fixing pin l, and horizontal notches 3a, 4a, respectively.
Continuous diagonal notches 3b and 4b are formed. Further, horizontal notches 3a and 4a for insertion are arranged at different levels in the left and right bracket plates 3.4 from the viewpoint of preventing them from falling off. Reference numeral 5 denotes a belt member, one end of which is locked to the fixing bracket 2 by the above-mentioned fixing pin l, and the other end is attached to the vehicle body by fastening means such as bolts, thereby attaching the fuel tank F to the lower surface of the vehicle body.

Furthermore, Fig. 10 shows another conventional example (Utility Model Application No.
(See Publication No. 1726.25).

A fixing pin 6 has a head 6a at one end and a through hole 6b into which a split pin 7 for preventing falling off is inserted and fixed at the other end. 8 is a fixed bracket, and a pair of opposing left and right bracket plates 9.10 have fixed pins 1.
It has round holes 9a and 10a for insertion. Reference numeral 11 denotes a belt member, and the fuel tank F is attached to the lower surface of the vehicle body by this belt member 11 in the same manner as in the previous example.

<Problems to be Solved by the Invention> However, in the first example above, although it has the advantage of being inexpensive and easy to work with, the fixing pin 1 is inserted in an incomplete state (as shown by the two-dot chain line in Fig. 9). Since it is difficult to detect even if the fixing pin 1 is inserted completely, there is a problem in that it takes a lot of man-hours to check whether the fixing pin 1 is completely inserted.

In the latter example, although incomplete insertion of the fixing pin 6 can be prevented, the fixing pin 6 is inserted into the round holes 9a and 10a, which are difficult to insert, and the split pin 7 is inserted to prevent it from falling off.
It was difficult to work because it had to be installed.

SUMMARY OF THE INVENTION Therefore, the present invention solves the above-mentioned problems and provides a fuel tank mounting structure in which a belt member can be easily and securely mounted, and the state in which the belt member is mounted can be easily checked.

Means for Solving the Problem> In order to achieve the above object, the fuel tank mounting structure according to the present invention has a pair of bracket plates mounted facing each other on the vehicle body, each having an insertion hole for inserting a fixing pin. and a fixing hole that prevents the fixing pin from falling off,
One end of the belt member inserted between the brackets is locked by the fixing pin inserted into the insertion hole, the fixing pin is moved to the fixing hole, and the belt member is rotated about the fixing pin. In a fuel tank mounting structure in which the fuel tank is attached to the lower surface of the vehicle body using the belt member, the other end of the belt member is secured to the vehicle body, and the fuel tank is attached near one end of the belt member in the width direction than the distance between the pair of fixed bracket plates. a protruding claw part is provided in the belt member, and the distance from the center of the fixing pin inserted into one end of the belt member to the claw part is set within the rotation range of the belt member, of the fixing pin located in the fixing hole. This is slightly larger than the distance from the center to the farthest point of the bracket plate.

Effect> According to the fuel tank mounting structure according to the present invention, the claw portion protruding in the width direction of the belt member is provided near the fixing pin mounting position of the belt member, so that the width of the belt member is wider than the gap between the bracket plates. It was formed to be large. Then, only when the fixing pin is fully inserted into the fixing hole, the hook from the fixing pin to the hook can be rotated from the insertion direction to the normal belt member installation direction without getting caught on the bracket plate. Set the interval. For this reason, when the fixing pin is incompletely inserted (meaning the fixing pin is not in the fixing hole), the claw of the heald member gets caught on the bracket plate, causing the belt member to move further than the normal mounting position. , the end of the belt member on the opposite side of the fixing pin cannot reach the attachment position to the vehicle body. This makes it easy to detect that the fixing pin is incompletely inserted.

Embodiment A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

F is a fuel tank, and 2o is a belt member.

The belt member 20 is made of a rigid material that does not expand or contract and has a shape that corresponds to the shape of the lower surface of the fuel tank F, as shown in FIG. At one end thereof, there is a wrapped portion 2°a for the fixing pin 21, and near this wrapped portion 2Oa, it protrudes in the width direction of the belt member 20 and has a width wider than the interval between both bracket plates 22 and 22, which will be described later. A claw portion 23 for restricting rotation of the belt member 20 is provided. The other end of the belt member 20 is attached to a mounting bracket 2 of the vehicle body.
4 is formed with a through hole 20b for bolting. The fixing pin 21 also has heads 21a and 2 at both ends.
1b, and one head 21b has a tapered tip to facilitate insertion into the winding portion 20a of the belt member 20 (see FIG. 3).

A fixing bracket 25 is fixed to the lower surface of the vehicle body. This fixing bracket 25 has the aforementioned pair of opposing bracket plates 22,22, and this bracket plate 22 has an insertion hole for inserting a fixing pin having a diameter at least larger than the head 21b of the fixing pin 21. 2
2a, and heads 21a, 2 which are provided continuously thereto.
A fixing hole 22b having a diameter smaller than 1b but larger than the shaft portion 21c is formed through the introduction portion 22C (length m). Here, m is set to be sufficiently longer than α (indicating the gap between the edge of the bracket plate 22 and the claw part 23) so that the fixing pin 21 does not fall off (see FIGS. 5 and 5). (See Figure 6). In the rotation range R of the belt member 20 between the insertion direction of the belt member 20 (direction A in FIG. 3) and the normal mounting direction of the belt member 20 (direction B in FIG. 4), L= The claw portion 23 is formed at a position L from the center of the fixing pin 21 so as to satisfy the relationship A+α (see FIGS. 5 and 6). Here, l is the rotation range (belt member 20
The distance to the farthest point of the bracket plate 22 in R between the insertion direction and the regular belt member 20 attachment direction is shown.

Next, a procedure for attaching the fuel tank F using the belt member 20 will be explained.

Insert one end of the belt member 20 between both bracket plates 22 of the fixed bracket 25, and insert the fixing pin 21 through the insertion hole 22a of the bracket plate 22 into the wrapped portion 20 of the belt member 20.
Insert into a. Then, the fixing pin 21 is pulled down from the insertion hole 22a through the introduction part 22c to the fixing hole 22b, so that the belt member 20 is fully inserted (the fixing pin 21 is inserted into the fixing hole 22b).
b) (see Figures 3 and 4). In this way, the fixing pin 21 is attached to the fixing hole 22b.
When it is pulled down to the position indicated by the solid line, it is fully inserted, so as shown in Fig.
It can be rotated freely to the regular belt member attachment position. next,
The other end of the belt member 20 is bolted to a mounting bracket 24 on the vehicle body.

In this way, the claw portion 23 is provided near the mounting position of the fixing pin 21 on the belt member 20, and only when the fixing pin 21 is fully inserted can the belt member 20 be moved from the insertion direction (direction A in the figure) to the normal mounting direction ( Since the fixing pin 21 is configured to rotate in the direction B in the figure, when the fixing pin 21 is incompletely inserted, the belt member 2
Since the claw portion 23 of the belt member 0 will be caught on the bracket plate 22 and take a long detour (see FIG. 7), the opposite end of the belt member will not be able to reach the mounting bracket 24 of the vehicle body. As a result, it is easily recognized that the fixing pin 21 is incompletely inserted, thereby eliminating the need for a check process and reducing the number of man-hours.

In the above embodiment, the belt member 20 is made of a rigid material with no flexibility, but the invention is not limited to this. If the claw portion 23 is rigid, the other parts are made of a flexible material with no elasticity. A similar effect can be obtained by using parts.

<Effects of the Invention> The fuel tank mounting structure according to the present invention has the content as described above, and the belt member is attached only when the fixing pin is completely inserted near the fixing pin attachment position of the belt member. A claw portion for restricting rotation of the belt member is provided at a position where the belt member can rotate from the insertion direction to the normal belt member attachment direction. Therefore, when the fixing pin is incompletely inserted, the claw part of the belt member gets caught on the edge of the bracket plate.
The other end of the belt member cannot reach the fixing position to the vehicle body. This makes it easy to check whether the fixing pin is fully inserted, eliminating the need for a check process, and reducing the number of man-hours.
