At present, the front lower protective device installed on the truck is generally integral. When a part breaks, it needs to be replaced as a whole, thereby increasing the cost of use. During installation, it needs to be hoisted by a small crane, and a kind of vehicle type is equipped with a kind of protective device, which not only increases the technological investment, but also cannot realize the generalization of the product, which is the weak point in the prior art. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a front lower protection device for trucks with strong versatility and easy replacement in view of the deficiencies in the prior art. the

This program is realized through the following technical measures: the front lower protective device for the truck includes a hollow protective beam, the protective beam is fixedly connected with an adjusting bracket, and the adjusting bracket is fixedly connected with a fixed installation bracket; There is a horizontal adjustment flat hole matched with the adjustment bracket. The adjustment bracket includes a U-shaped bracket and an inclined bracket fixedly connected with it. The U-shaped bracket is provided with a positioning hole matched with the horizontal adjustment flat hole. The side of the inclined bracket is provided with longitudinally arranged Positioning holes, the side of the fixed mounting bracket is provided with through holes corresponding to the number and positions of the positioning holes on the inclined support, and the top surface is provided with vehicle frame mounting holes. the

The two ends of the protective crossbeam are arc-shaped ends matching the shape of the bumper, so that the protective crossbeam can be close to the bumper, which improves the aesthetics of the vehicle and reduces the drag coefficient of the vehicle. the

A reinforcing rib is provided between the U-shaped bracket and the inclined bracket to enhance the impact resistance of the whole device. the

Lightening holes are also provided on the side of the above-mentioned fixed mounting bracket to reduce the weight of the fixed mounting bracket and reduce the weight of the entire protective device. the

The cross-section of the above-mentioned protective beam is rectangular. the

The beneficial effect of this scheme can be known from the description of the above scheme. In the front lower protective device for trucks, the fine adjustment of the X-axis direction of the entire device is realized through the horizontal adjustment flat hole, and the Y-axis of the entire device is realized through the adjustment bracket and the fixed mounting bracket. The movement in the Z-axis direction can be conveniently adjusted according to different models, and its versatility improves the flexibility of installation. The device is a split structure with a simple structure. It can be installed separately during installation, which saves the extra investment caused by the overall hoisting of a small crane. It does not need to be replaced as a whole, thereby reducing the cost of use. It has high strength and is safe and reliable. It can be seen that, compared with the prior art, the utility model has substantive features and progress, and the beneficial effects of its implementation are also obvious. the

Detailed ways

In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings. the

A front lower protective device for a truck, as shown in the figure, it includes a hollow protective beam 1 with a rectangular cross section, the protective beam 1 is fixedly connected with an adjustment bracket 3, and the adjustment bracket 3 is fixedly connected with a fixed installation bracket 2. The protective beam 1 is a steel stamping part. The two ends of the protective beam 1 are arc-shaped ends matching the shape of the bumper. The fillet radius of the arc-shaped end is 300mm. The protective beam 1 can be attached to the bumper to Improve the aesthetics of the vehicle and reduce the drag coefficient of the vehicle. The upper and lower end faces of the protective crossbeam 1 are provided with horizontal adjustment flat holes 4 matched with the adjustment bracket 3 . the

The adjusting bracket 3 includes a U-shaped bracket 9 and an inclined bracket 6 fixedly connected thereto. The U-shaped bracket 9 is stuck on the outside of the protective beam 1 . A reinforcing rib 7 is arranged between the U-shaped bracket 9 and the inclined bracket 6 . The upper and lower end surfaces of the U-shaped bracket 9 are provided with positioning holes 8 that cooperate with the flat holes 4 for horizontal adjustment, and the side of the inclined bracket 6 is provided with multiple rows of longitudinally arranged positioning holes 5 . the

The bottom of the fixed mounting bracket 2 sides is provided with through holes 12 corresponding to the number and positions of the positioning holes 5 on the inclined bracket 6, the top of the fixed mounting bracket 2 sides is provided with a lightening hole 11, and the top surface of the fixed mounting bracket 2 is provided with Vehicle frame installation hole 10, vehicle frame installation hole 10 cooperates with connecting bolt and vehicle frame is fixedly installed on the fixed installation bracket 2. the

During installation, at first the fixed mounting bracket 2 is installed on the lower wing surface of the vehicle frame, and the lower wing surface of the vehicle frame is punched with standard holes with a spacing of 50mm, so that the fixed mounting bracket 2 can be moved along the Y-axis direction of the vehicle. Then the adjusting bracket 3 is connected with the fixed mounting bracket 2 through bolts, and the fixed mounting bracket 2 can be moved along the Z-axis direction of the vehicle as required. Finally, the protective crossbeam 1 is installed. Since the horizontal adjustment flat hole 4 is provided on the protective crossbeam 1, it is beneficial for installation and fine-tuning along the X-axis direction of the vehicle. the

The technical features not described in the utility model can be realized by the prior art, and will not be repeated here. the
