[0001]
[Industrial application fields]
The present invention relates to a stud fixing tool that is attached to a member to which a stud is fixed by engaging with a stud having a screw or a peripheral groove formed on an outer peripheral surface thereof, and is suitable for attaching other mounting parts to the member. And a component mounting structure.
[0002]
[Prior art]
For example, there is a stud fixing tool that holds a fuel pipe or a brake pipe of an automobile on a panel such as a vehicle body as a stud fixing tool that attaches a mounting part to a member to which the stud is fixed by locking to a screw stud or the like. This stud fixture is often used because it eliminates the need for drilling holes in the panel. In the stud fixture, if the stud locking part is sufficiently depressed, the stud is sufficiently latched. However, if the stud is not sufficiently depressed, the stud is not completely locked and the pipe cannot be attached. Become imperfect. Therefore, it is desirable that it can be confirmed that the stud locking portion is sufficiently pushed into the stud.
[0003]
One stud fixture that meets this demand is disclosed in Japanese Patent Laid-Open No. 7-83357. The stud fixing device has a stud locking portion formed with a stud receiving hole through which the stud penetrates, and the outlet of the stud receiving hole is broken by the stud when the stud fixing device is in a proper mounting position. By confirming visually that the film is blocked and the film is torn or to hear the bursting sound to be broken, it can be found that it is a normal mounting position. Japanese Patent Application Laid-Open No. 7-174127 discloses a stud fixing tool including a movable cover that displays a normal insertion state by bulging deformation caused by a stud protruding operation at an outlet portion of a stud receiving hole of a stud locking portion. According to this stud fixing tool, when the stud is completely pushed down to the predetermined depth position of the stud receiving hole, the movable cover is changed in shape so as to bulge upward, and the operator determines whether or not this change has occurred. By this, it is possible to confirm the mounting of the stud fixing tool. Further, Japanese Patent Laid-Open No. 7-217633 discloses that a stud receiving hole in which a stud receiving hole in which a stud is received and from which a tip of the stud extends is formed is closed at the stud outlet of the stud receiving hole. A pair of elongated elastic pieces extending in the manner described above is provided, and the elastic pieces are pushed out by the positions of the studs protruding from the outlet portion to close the stud receiving holes, and depending on the positions, the elastic pieces are pushed into the stud locking portions. Stud fixtures are disclosed that allow visual inspection of whether or not is appropriate.
[0004]
[Problems to be solved by the invention]
The stud fixing tool described above is preferable because it has a confirmation means that the stud locking portion is sufficiently pushed into the stud. However, there is room for improvement in these stud fixtures. Usually, in the mounting operation to the stud, a finger or the like is applied to the exit portion of the stud receiving hole of the stud locking portion to push the stud locking portion into the stud. In the stud fixing tool described above, at the outlet portion of the stud receiving hole, a film (Japanese Patent Laid-Open No. 7-83357), a movable cover (Japanese Patent Laid-Open No. 7-174127), and a pair of elongated elastic pieces (Japanese Patent Laid-Open No. 7-217633) Therefore, it is not possible to attach a finger directly to the exit portion, so skill is required to install the stud fixture in a balanced manner. Further, in the case of a film (Japanese Patent Laid-Open No. 7-83357) or a movable cover (Japanese Patent Laid-Open No. 7-174127), if the film or the movable cover is damaged, the function of confirming the original push into the stud is lost. Further, since the stud fixing tool has a film, a movable cover, and a pair of elongated elastic pieces at the outlet portion of the stud receiving hole, the stud is not necessary for confirming that the stud is sufficiently pushed. It is necessary to reach the outlet of the stud receiving hole. For this reason, the height of the stud engaging portion becomes high corresponding to the length of the stud, and the stud fixing tool becomes larger than necessary.
Accordingly, an object of the present invention is a stud fixing tool capable of confirming that the stud is sufficiently pushed, and does not require skill in the mounting operation, and the stud locking portion can be kept low in height. It is to provide a fixture.
[0005]
[Means for Solving the Problems]
In order to achieve such an object, according to the present invention, there is provided a stud fixture that can be attached to a member to which the stud is fixed by engaging with a stud having a screw or a circumferential groove formed on the outer peripheral surface thereof. A pair of stud locking portions formed with stud receiving holes through which the studs pass, and a portion of the stud locking portion in front of the outlet of the stud receiving holes is closed to close the path of the studs. Opening and closing pieces are provided, and the pair of opening and closing pieces are formed to be raised on both sides in the direction of opening the stud path by the tips of studs extending to the outlet, and each opening and closing piece is raised by the tips of the studs. tip of the opening and closing piece are dimensioned not to protrude from said stud receiving hole outlet in a state, the stud engagement part, the closing piece stud A shape from the outlet side of the stud receiving hole can be seen the leading face of the stud in the state of being caused by the end, the stud fastener is provided, characterized in that.
[0006]
[Action]
When the stud is fully pushed into the stud receiving hole, the pair of opening and closing pieces of the stud locking portion hardly protrudes from the top of the housing portion when opened on both sides by the protruding operation of the stud, but opens on both sides. When viewed from the exit direction of the stud receiving hole, the entire tip surface of the stud, i.e., the tip of the stud, looks round, and the operator can know the proper pushing state to the stud, while the stud tip surface is partially If it can be seen, the push is insufficient, so the operator only needs to push further, and in this way, the degree of push into the stud is easily known by observing the stud tip that can be seen through the opening and closing piece. And ensure that the stud is pushed to a sufficient position.
[0007]
In the present invention, the stud receiving hole can be formed as a long hole, and each open / close piece can be formed of a plate-like body extending in the longitudinal direction of the elongated hole-shaped stud receiving hole. The error can be absorbed. In addition, a guide for guiding the stud to the center of the pair of opening / closing pieces can be formed in the stud locking portion at the base of each opening / closing piece. As a result, the opening and closing pieces are opened in a well-balanced manner, and the tip end surface of the stud is more reliably confirmed. In addition, the fixture can be formed to have a color that contrasts with the stud, and the tip end surface of the stud can be confirmed more reliably. Similarly, you may make it have the color which makes the front end surface of a stud contrast with an opening-and-closing piece.

[0009]
The pipe holding portions 9 provided on both sides of the stud engaging portion 6 are formed by a substantially U-shaped groove 10 opened upward, and an elastic claw 11 extends obliquely from the upper portion toward the bottom surface and is pushed in. The pipes are not pulled out. The pipe holding portions 9 are formed with grooves 10 having various sizes so as to support pipes having various diameters. A stud receiving hole 5 for receiving the screw stud 2 is formed in the stud locking portion 6. The stud receiving hole 5 is formed as a long hole that is long in a direction parallel to the longitudinal direction of the pipe 7 held by the pipe holding portion 9 (direction perpendicular to the paper surface of FIG. 6). On the entrance side of the stud receiving hole 5 (upper part in FIG. 1), a first locking claw 13 is formed to be locked to the threaded portion of the received stud. The first locking claws 13 are arranged to face each other across the axis of the stud receiving hole 5, and each locking claw is formed by a plate-like body extending in the longitudinal direction of the stud receiving hole 5. In addition, a pair of second locking claws 14 are formed below the first locking claws 13 to strengthen the locking to the studs. In addition, the stud locking portion 6 is formed with a pair of spring pieces 15 for preventing rattling at the entrance portion of the stud receiving hole 5 so as to sandwich the receiving hole 5 so that the stud fixing tool is pressed against the panel. When installed, it prevents rattling and strengthens the retainer.
[0010]
A pair of opening / closing pieces 18 and 18 are provided at the stud engaging portion 6 in front of the outlet 17 of the stud receiving hole 5 (upper side in FIG. 5 and the like) so as to close the course of the stud. The pair of opening / closing pieces 18 and 18 normally closes the stud receiving hole 5, but are formed to be raised on both sides in the direction of opening the stud path, that is, the stud receiving hole 5, by the tip of the stud extending to the outlet 17. Has been. Each open / close piece 18 is formed in such a size that the tip of the open / close piece does not protrude from the outlet 17 of the stud receiving hole 5 in a state where it is raised by the stud tip (see FIG. 7A). Each opening / closing piece 18 is formed of a plate-like body extending in the longitudinal direction of the elongated hole-shaped stud receiving hole 5, and the position of the stud fixing tool 1 in the longitudinal direction of the pipe can be adjusted. Mutual distance errors can be absorbed.
[0011]
A pair of rib-shaped guides 19 for guiding the stud 3 to the center of the pair of opening / closing pieces 18, 18 are formed on the inner wall of the stud locking portion 6 at the root portion of each opening / closing piece 18. By the pair of guides 19, 19, the stud axis is evenly locked to the pair of first locking claws 13, and the studs are equally locked to the pair of second locking claws 14, and the locking force is strengthened. In addition, the stud 3 is guided to the center of the pair of opening and closing pieces 18 and 18 so that the opening and closing pieces 18 are opened in a well-balanced manner, and visual confirmation of the tip end surface of the stud at the time of opening is further ensured. Further, the entire stud fixing tool 1, the stud locking portion 6, or at least the opening / closing piece 18 is formed so as to have a color that contrasts with the tip end surface of the stud, Confirmation may be made more reliable. Similarly, the front end surface of the stud may have a color that makes a contrast with the opening / closing piece 18, the stud locking portion 6, or the entire stud fixture 1.
[0012]
The pair of opening / closing pieces 18 are normally in a posture to close the stud receiving hole 5, but are pushed by the tip of the stud that has entered the stud receiving hole 5 and are raised from the posture to close the stud receiving hole. When the opening / closing piece 18 is raised, the tip end surface of the stud can be seen from the outlet side of the stud receiving hole 5. The pair of opening / closing pieces 18 into which the stud engaging portion 6 is pushed into the stud to a sufficient position can be opened widely so that the entire front end surface of the stud can be seen (that is, the round end surface can be seen). If the push-in is insufficient, the entire tip surface of the stud cannot be seen. Therefore, the operator can know whether or not the stud locking portion 6 is sufficiently pushed by the shape of the tip surface.
[0013]
In order to attach the pipe to the panel using the stud fixing tool 1 having such a configuration, as shown in FIG. 6, first, a large number of pipes 7 are arranged at predetermined positions at the pipe holding portions 6 of the stud fixing tools 1. It is pushed into the groove 10 and gripped. Next, in a state where the stud fixture 1 is attached to a predetermined position of the plurality of pipes 7, the plurality of screw studs are brought into a certain position of a panel such as a vehicle body fixed to the predetermined position. FIG. 6 shows the relationship between one screw stud 3 fixed to the panel 2 and one stud fixture 1. For each stud fixing tool 1, an operation is performed in which the finger 21 or the like is applied to the outlet 17 of the stud receiving hole and the corresponding stud 3 is pushed in the direction of the arrow 22 as it is. By this pushing, the stud 3 enters the stud receiving hole 5 and is locked to the first locking claw 13 and the second locking claw 14, and the front end of the stud 3 is regulated by the guide 19 while being opened and closed. The pieces 18 are extruded to the outlet side, and the open / close pieces 18 are raised on both sides.
[0014]
This pushing must be performed until the stud locking portion 6 is sufficiently pressed against the panel 2. If the push-in is insufficient, the stud fixture 1 will be incompletely installed and the pipe 7 will be incompletely installed. FIGS. 7A and 7B show a state where the pressing is sufficiently performed. In FIG. 7 (A), when the tip 23 of the stud 3 is positioned at the outlet 17 of the stud receiving hole 5, the pair of opening and closing pieces 18, 18 are raised on both sides from the posture of closing the stud receiving hole, thereby opening the stud receiving hole. To do. 7 (B) shows a bottom view of the stud fixture 1 of FIG. 7 (A) when the push is sufficiently performed, and as shown in FIG. By visually observing the stud receiving hole 5 from the side, the entire tip 23 of the stud 3, that is, a round tip can be seen. If the stud tip 23 looks round, the operator can confirm that the stud fixture 1 has been fully pushed into the panel 2. In that case, the confirmation can be further facilitated by making the stud tip 23 white, for example, so that the opening / closing piece 18 and the stud tip 23 have different colors so as to make a contrast.
[0015]
8A and 8B show a state in which the stud locking portion 6 is not sufficiently pressed against the panel 2. If the push-in is insufficient, the opening and closing pieces 18, 18 are small. Therefore, as shown in the bottom view of FIG. 8B, when the operator looks at the stud receiving hole 5, the tip 23 of the stud 3 does not look round. Thus, when the whole stud front-end | tip 23 is not visible, it can confirm that pushing into the stud of the stud latching | locking part 6 is inadequate. In this case, the operator may push the stud locking portion 6 with a finger or the like near the outlet 17 of the stud receiving hole 5 on the bottom surface of the stud locking portion 6. After the pushing, it can be confirmed again from the outlet side of the stud receiving hole 5 that the tip 3 of the stud 3 is round. Thereby, it can ensure that the stud fixing tool 1 is pushed in to a sufficient position.
[0016]
In the above embodiment, the stud fixture is exemplified as a fixture for attaching a pipe, but other components may be attached. As an example, there is a clamp that holds a decorative part and is attached to a vehicle body panel, and there is another clamp that holds the other panel against the panel. Furthermore, the stud fixture does not need to attach other attachment parts. In the embodiment, the stud has been described as a screw stud having a screw formed on the outer peripheral surface, but may be a stud having a circumferential groove.
[0017]
【The invention's effect】
According to the stud fixing device of the present invention, when the stud is sufficiently pushed into the stud receiving hole, the pair of opening and closing pieces of the stud locking portion are opened from both sides by the stud protruding operation, and are not removed from the top of the housing portion. Although it hardly protrudes, it opens to both sides, and when viewed from the exit direction of the stud receiving hole, the entire tip end surface of the stud, that is, the tip of the stud looks round, and the operator can know the proper pushing state to the stud. On the other hand, if the stud tip surface is partially visible, the push-in is insufficient, so the operator only needs to push in further, and in this way, by visually observing the stud tip that can be seen from the open / close piece. The degree of pushing into the stud can be easily known, and the stud can be surely pushed into a sufficient position. And, when the pair of opening and closing pieces of the stud locking part are opened on both sides by the stud protruding operation, they hardly protrude from the top part of the housing part, so that a finger is directly applied to the outlet part of the stud receiving hole of the stud locking part. The stud fixing tool can be attached in a well-balanced manner, requiring no skill in the mounting operation, and the opening / closing piece does not protrude from the stud receiving hole, so that the height of the stud locking portion can be kept low. And the height of the stud fixture can be reduced.
