Description

Back door lock fixing device on car rear wall reinforcement plate

technical field

The utility model relates to an automobile part, in particular to a back door lock fixing device on an automobile rear wall reinforcement plate.

Background technique

With the development of the economy and the improvement of people's living standards, the automobile has become one of the important means of transportation for people to travel, and the parts on the automobile are indispensable components of the automobile. The back door lock fixing device on the reinforcement plate of the rear wall of the car is one of them. The traditional back door lock fixing device is fixed by the shape of the fixing plate, which is inconvenient to fix, and the nut plate fixing plate is relatively small. The contact area of the plate is relatively small, it is not easy to weld during welding, and the welding tongs interfere with the workpiece, resulting in low production efficiency.

As mentioned above, the prior art has the following deficiencies: the back door lock fixing device is fixed by the fixed plate surface, which is inconvenient to fix, and the nut plate fixed plate is relatively small, so the contact area with the nut plate is relatively small, and it is not easy to weld when welding. It is easy to be welded, and the welding tongs interfere with the workpiece, resulting in low production efficiency.

Contents of the invention

The utility model solves the problem that the back door lock fixing device in the prior art is fixed by the fixed plate surface, which is inconvenient to fix, and the nut plate fixed plate is relatively small, so the contact area with the nut plate is relatively small, and it is not easy to weld Welding, and interference between the welding tongs and the workpiece, and low production efficiency, a back door lock fixing device on the rear wall reinforcement plate of the automobile that does not interfere with the welding tongs and the workpiece and has high production efficiency is provided.

The above-mentioned technical purpose of the utility model is mainly solved by the following technical solutions: a back door lock fixing device on the rear wall reinforcement plate of an automobile, including a back door lock fixing plate, on which a back door lock nut plate is connected, the The nut plate is fixedly connected on the back door lock fixing plate through the nut plate fixing plate, and it is characterized in that the lower side of the back door lock fixing plate is provided with positioning bumps, and the two ends of the nut plate fixing plate are provided with positioning gaps, and the positioning The protruding point is adapted to the positioning notch, and the nut plate fixing plate is widened. In this way, when preparing for welding, the positioning bumps of the back door lock fixing plate and the positioning gap of the nut plate fixing plate are used for positioning, so that the positioning is more accurate, and then welding tongs will not produce welding tongs and workpieces. The problem of interference, and the original relatively small nut plate fixing plate is widened, so that it will not be difficult to weld due to the small contact area during spot welding.

Preferably, the two ends of the nut plate are provided with positioning holes, and the middle of the nut plate is shaped like a few characters. The nut plate fixing plate is in the shape of a few characters, and this shape is adapted to the nut plate in the middle of the shape of a few characters, and the two are assembled into a cross shape. The nut plate in a few characters is to match the shape of the back door lock fixing plate, and then use the positioning holes at both ends to fix it on the back door lock fixing plate, so that it is fixed more firmly.

The utility model is ingeniously conceived. Compared with the prior art, the utility model has the following beneficial effects through the cooperation of the positioning notch and the positioning bump:

It is convenient to fix, and the nut plate fixing plate is widened, so that the contact area with the nut plate is relatively large, and it is easy to weld during welding, and the welding tongs do not interfere with the workpiece, and the production efficiency is high.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model.

Detailed ways

The technical solutions of the present utility model will be further described below through the embodiments and in conjunction with the accompanying drawings.

Example 1. See Fig. 1, this example is a kind of back door lock fixing device on the automobile back wall reinforcement plate, comprises back door lock fixing plate 1, is connected with back door lock nut plate 2 on it, and this nut plate 2 passes through the nut plate fixing plate 3 is fixedly connected to the back door lock fixing plate 1, the lower side of the back door lock fixing plate 1 is provided with a positioning bump 4, and the two ends of the nut plate fixing plate 3 are provided with positioning gaps 5, the positioning bump 4 and the The positioning gap 5 is adapted, the positioning bump 4 is in the shape of up and down, and the positioning gap 5 is an arc-shaped mouth. Utilize the positioning of the positioning bump 4 and the positioning gap 5 for welding on a fixed electric welding machine. It can prevent the welding tongs and the workpiece from interfering, and the production efficiency is improved; and the nut plate fixing plate 3 is widened, which increases the contact area between the nut plate fixing plate 3 and the back door lock fixing plate 1, making welding easy .

Wherein, the two ends of the nut plate 2 are provided with positioning holes 6, and the middle of the nut plate 2 is shaped like a few characters. Described nut plate fixing plate 3 becomes several fonts, and this shape and the middle nut plate 2 that forms several fonts are adapted, and both become cross after assembling. The nut plate is fixedly connected with the back door lock fixing plate 1 through the positioning hole 6, and the nut plate fixing plate 3 is fixed on the back door lock fixing plate 1 by welding.

It is obvious to those skilled in the art that the present utility model can be changed in many ways, and such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art are intended to be included within the scope of this claim.
