Description

[Detailed Description of the Invention] The present invention relates to an improvement of a jacking device mounting device. In the conventional jacking device, as shown in FIG. 1, a bracket 2 is welded to a floor panel 1 of a vehicle body. A two-pronged piece 3 is fixed to the bracket 2, and a bolt 4 is passed through between the two-pronged piece 3 and the bracket 2.

When installing the jack 5, the jack base 6 is placed on the bracket 2, and then the butterfly nut 7 is screwed onto the bolt 4, and the jack 5 is clamped between the bracket 2 and the fork part 3, thereby fixing it to the vehicle body. can.

However, in order to make the jack base 6 into a shape that will not shift due to vibrations when the vehicle is running, the bracket 2 must be press-formed, and since the two-pronged portion 3 is welded to the bracket 2, the number of machining steps is increased accordingly. increases,
Furthermore, there was a drawback that the number of parts increased.

In view of these drawbacks, the following mounting method is also available.

In other words, a bolt hole is drilled in the floor panel 1, a bolt is passed through the hole, and the bolt head is directly connected to the lower surface of the floor panel, and a bolt insertion hole is pre-drilled in the jack base 6 at the bolt thread portion protruding from the upper surface of the floor panel. In this method, the base 6 is tightened and fixed with nuts through the bolt holes, but in this case, since bolt holes are drilled in the floor panel, there is a problem that rainwater from the bottom of the floor panel can enter the vehicle interior through the bolt holes.

The present invention has been devised in view of the above, and in which a jacking device having a jacking base at the bottom of the jacking body is attached to a car body floor panel, a bracket having a horizontal surface portion having a substantially horizontal plane is provided on the car body floor panel, A hole for bolt insertion is drilled in the horizontal surface of the bracket, and the bolt head is connected to the lower surface of the horizontal surface to secure the bolt, and the threaded portion of the bolt protruding from the upper surface of the horizontal surface is passed through. forming a bolt through hole in the jacking base, and inserting the bolt into the bolt through hole of the jacking base when the jacking device is installed;
The object of the present invention is to provide a mounting device for a jacking device, characterized in that the jacking device is mounted on the bracket by screwing a nut onto the bolt.

For this reason, by simply forming a hole for the bolt to pass through the jack base and fixing a bolt head to the bottom of the bracket fixed to the vehicle floor panel to penetrate this hole, rainwater can enter from outside the vehicle. It is possible to obtain a jack mounting device which can prevent the above-mentioned damage and has an extremely simple structure, and has an excellent effect of reducing costs and making it commercially advantageous.

Next, the present invention will be explained in detail based on the embodiment shown in FIGS. 2 to 4. First, reference numeral 8 is a jack base at the bottom of the jack body 9, 10 is a base for operating the jack, and 11 is a floor panel F of the vehicle body. This bracket is provided on the rear inclined surface and has a horizontal surface portion 11'.

12 is a bolt that is inserted into a hole drilled in the bracket 11 and its head is welded to the bottom surface of the horizontal surface portion 11 of the bracket; 13 is a bush that is fitted into the outer periphery of the bolt; 14
15 is a bolt through hole drilled in the jack base 8, and a butterfly nut 15 is screwed onto the bolt 12.

Since this embodiment is configured as described above, when mounting the jacking device on the bracket 11, the bolt 12 is inserted into the port 1 [through hole 14] of the jacking base 8, and then the butterfly nut 15 is screwed onto the bolt 12. By doing this, attach the jack base 8 to the bracket 11 and the butterfly nut 1.
It can be held between 5 and 5.

On the other hand, when the jacking device is to be used after being removed from the bracket 11, it is sufficient to simply loosen the butterfly nut 15 and remove the jacking base 8 from the bolt 12.

According to the device of this embodiment, the horizontal surface portion 11' of the bracket 11
Insert the bolt 12 into the hole drilled in the horizontal surface part 11.
'Since the bolt head is connected to the lower surface, it is possible to prevent rainwater from entering the vehicle interior from outside the vehicle.
