Description

  The present invention relates to a mounting structure for a mounting component that can easily mount a mounted component on a fixed seat formed on a mounting member such as a vehicle interior or a vehicle interior.

Conventionally, bolts and nuts are commonly used as attachment means when attaching a part to be attached to a fixed seat of an attachment member (see, for example, Patent Document 1).
The apparatus for attaching a counterweight in a construction machine or the like described in Patent Document 1 is such that when a part to be attached (counterweight) is fixed to an attachment member (frame) with a bolt and a nut, the bolt is rotated and screwed onto the nut. When mating, the nut may rotate with the bolt. In order to prevent the nut from rotating, an anti-rotation plate is integrally formed on the mounting bracket.

Japanese Patent Laid-Open No. 6-300023 (FIG. 1)

  In a mounting bracket for a counterweight mounting device in a construction machine or the like as in Patent Document 1, a detent plate portion bent in an L shape with respect to a washer plate portion is applied to one place on the outer peripheral surface of a nut. This prevents the nut from rotating with the bolt.

  However, in such bolts and nuts, when the bolts are screwed into the nuts, the nuts can be prevented from rotating together with the bolts, but the nuts on the opposite surface of the frame to the bolts are screwed together. If the nuts are not attached while gripping the nuts by hand, the nuts may fall.

  Thus, conventionally, when a nut that is one fixing member and a bolt that is the other fixing member are screwed to each other, an operator must screw the nut while holding both the nut and the bolt. Therefore, there was a problem that workability was bad.

  In particular, when a mounted part (counterweight) or a mounting member (frame) is large, a bolt placed on the front side thereof and a nut placed on the back side thereof are used by one worker. When holding and bolting at the same time by hand, it is difficult to tighten the bolt because the hand does not reach the nut.

  Then, this invention makes it a subject to provide the attachment structure of the attachment components which can attach to-be-attached components easily to the attachment member which consists of panel materials etc., for example.

As a means for solving the problem, the invention of the mounting part mounting structure according to claim 1 fixes the mounted part to the mounting member by screwing one fixing member and the other fixing member. The mounting member is integrally formed with a fixed seat on the surface of the mounting member, and the fixed seat is formed on the seat surface. The other fixing member is disposed with an attachment part interposed therebetween, and a holding portion for holding and locking the one fixing member is formed on the back surface side of the seating surface, and the other fixing member is a bolt The one fixing member includes a nut having a flange portion and the bolt is screwed thereto, and the holding portion is formed with an opening formed on a side surface of the fixing seat and within the opening. And an engagement space portion with which the nut engages. A pair of L-shaped support pieces that form a part of the space and sandwich the nut inserted in the engagement space, and the pair of L-shaped support pieces from the pair of L-shaped support pieces toward the back surface of the seating surface. Protruding portions are formed to form convex portions that hold the flange portion with the back surface, and through holes into which the bolts are inserted are formed on the seat surface .

  According to the invention of the mounting structure for mounting parts described in claim 1, the mounting member is formed with the holding portion that holds the one fixing member on the fixing seat and prevents the rotation. For this reason, when an operator screws one fixing member and the other fixing member, by holding the one fixing member on the holding portion, the one fixing member is screwed without being gripped by hand. Can be made. As a result, the one fixing member and the other fixing member can easily fix the mounted component to the mounting member, so that the workability of the mounting work can be improved.

According to the invention of mounting structure for fitting according to claim 1, one of the fixing member, by being inserted into the engaging space part from the opening, it is held engaged with the holding portion. Even if the other fixing member is inserted into the holding portion through the through hole of the seating surface of the fixing seat and rotated, one fixing member is held by the holding portion and does not rotate together with the other fixing member. It is easily screwed into one fixing member. For this reason, when the other fixing member is screwed to one fixing member to fix the attached component to the mounting member, it is not necessary to grasp one fixing member by hand, thereby improving the workability of the mounting work. Can be made.
