Description

The utility model belongs to the field of ladders.

Generally large trucks or military vehicles, due to the high height of the car body, are mostly equipped with ladders at the rear or side of the car body in order to facilitate personnel to get on and off the car body, and the usual car body ladders are all fixedly welded on the car body and cannot It can be folded at will, and it still occupies space when not in use, causing certain obstacles around the car body; there are many opportunities for military trucks or other trucks to carry loads, and conveying equipment is often provided with the vehicle for use in order to save manpower when moving goods. It is transported down and temporarily erected for use. This method is not only inefficient but also extremely inconvenient.

In view of the above-mentioned deficiencies, the utility model aims to:

1. Provide a multi-purpose ladder with considerable mobility that can hide the car body when not in use. When in use, the ladder can be pulled out for use, the ladder can be turned over, and one side has a pedal for people to get on and off the car body; The other side is equipped with rollers for conveying goods;

2. The provided ladder can form a four-link structure with a fixed upper end when it is stretched, and its pedals are always kept parallel to the top surface, and will not be inclined or unstable due to uneven ground;

3. The ladder can be taken down and used for other purposes when necessary.

The utility model is made up of ladder foot 9,10 and pedal 11, is characterized in that:

1. Open a space on the side or rear side of the car body, and fix a pair of groove rails 2 with opposite openings on both sides of the space; there are a square frame-shaped front rail body 3 and a rear rail body 4, with a The pivot 5 is connected and can make the front body rail 3 turn over, and the connection between the rear rail body 4 and the pivot 5 is locked by the wing bolt 7 and can be disassembled and separated; the connection between the rear rail body 4 and the pivot 5 is a The rotating part 8 can make the front rail body 3 rotate up and down along the rotating part 8 to form different angles with the rear rail body 4 .

2. The ladder 1 is composed of a pair of front ladder feet 9 and rear ladder feet 10. A number of pedals 11 are pivotally arranged between the front and rear ladder feet 9 and 10, so that the front and rear ladder feet 9 and 10 can be synchronized in parallel. Move, on the rear ladder feet 10, several rollers 12 are pivotally arranged in addition, and the upper ends of the front and rear ladder feet 10 are pivotally arranged on the front rail body 3 to be rotatable (Fig. 1).

3. When the utility model is in use (Fig. 2), firstly pull the ladder 1 and the front rail body 3 out of the vehicle body from the groove rail 2, and then stretch the ladder 1 downward so that the front rail body 3, front, and A fixed upper four-link structure is formed between the rear ladder feet 9, 10 and the pedals 11. As long as the front ladder feet 9 are in contact with the ground, the ladder 1 can be firmly supported, and each pedal 11 is always kept in contact with the front rail body 3. Parallel to adapt to uneven ground.

4. When the front and rear ladder feet 9 and 10 of the present utility model are in the horizontal position, they can be completely superimposed (Fig. 3) and (Fig. 6), and the front rail body 3 is turned over by the pivot 5 to make the rear ladder of the ladder 1 The roller 12 of pin 10 faces upwards, and then the rotating part 8 of rear rail body 4 makes ladder 1 rotate under the folded state and supports on the ground or other objects, as the usefulness of conveying articles.

5. When the ladder of the present utility model is used as a conveyor belt (Fig. 4), the roller 12 on the rear ladder foot 10 is replaced with a conveyor belt 6 for conveying articles.

6. When the ladder 1 is not in use, stack it and put it into the car body by the groove rail 2 and fix it (Figure 5). After loosening the nut of the wing bolt 7 on the rear rail body 4, the ladder 1 can be removed Use alone.

Compared with the prior art, the utility model has the advantages of:

1. The ladder of the utility model can be hidden in the car body when not in use, so that there are no obstacles around the car body;

2. The ladder of the utility model can be stably supported on the ground, and its pedal area is large and always parallel to the front rail body, which has high stability;

3. After the front and rear ladder feet of the ladder of the present utility model are completely overlapped, the rollers can be turned upward, or the rollers can be changed to conveyor belts or flat plates to transport objects;

4. Loosen the nut of the wing bolt, take out the front rail body and other parts, and the ladder can be used for other purposes independently.

Example:

1. Figure 2 shows that after the utility model is pulled out from the car body, the four-link structure is lowered so that the front ladder foot 9 touches the ground, and the pedal 11 is naturally parallel to the front rail body, which can be used as a ladder;

2. Figure 3 shows that after the utility model is pulled out from the car body, the front and rear ladder feet 9 and 10 are completely overlapped and the front rail body 3 is turned over by the pivot 5, so that the roller 12 of the rear ladder foot 10 of the ladder 1 Face upwards, and then rotate the rotating part 8 of the rear rail body 4 to make the ladder 1 rotate in a folded state and support it on the ground or other objects for conveying goods;

3. FIG. 4 is another embodiment of the utility model for conveying goods, that is, the roller 12 can be replaced with a conveyor belt or a flat plate 6.
