Description

An anti-tip poster stand

technical field

The utility model relates to a poster frame, in particular to an anti-dumping poster frame.

Background technique

Although the existing poster racks are relatively simple in structure and relatively low in cost, they are easy to topple over. In addition to damaging the posters, the toppling of poster racks also affects the appearance of the city. Some poster stands use the principle of the stability of the triangle, which can indeed solve the problem of posters being easy to fall to a certain extent, but such a structure can only slow down the possibility of falling in a certain direction, and the opposite direction is still There is a relatively large possibility of dumping, and obviously this structure is unreasonable on some important occasions, so people need a more stable structure.

Utility model content

Aiming at the problems existing in the existing poster racks, the technical problem to be solved by the utility model is to provide an anti-tipping poster rack which can keep stable.

The technical problem to be solved by the utility model is achieved through such a technical scheme, which includes a poster frame, a column, a load-bearing block and a tripod, the poster frame is fixed on the top of the column, and the column at the bottom of the column is movably inserted into the center hole of the load-bearing block Inside, the load block is a square prism, and a tripod is respectively hinged on the four sides of the base of the load block. There are fixed rods.

Technical effect of the present utility model:

Because the utility model is equipped with tripods on the four sides of the base of the load-bearing block, the tripod adopts the outline surface of a tumbler. To ensure stability and ability to regain balance and avoid tipping.

Description of drawings

The accompanying drawings of the utility model are as follows:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of the connection between the weight block and the tripod in Fig. 1 .

In the figure: 1. Poster stand; 2. Column; 3. Weight block; 4. Tripod; 5. Fixing rod.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figures 1 and 2, the utility model includes a poster frame 1, a column 2, a load-bearing block 3 and a tripod 4, the poster frame 1 is fixed on the top of the column 2, and the cylinder at the bottom of the column 2 is movably connected to the load-bearing block 3 In the center hole, the weight block 3 is a square prism, and a tripod 4 is respectively hinged on the four sides of the base of the weight block 3 . Fixed rods 5 are connected between the sides or the sides of the load-bearing blocks.

The poster frame 1 is used for clamping posters; a small-diameter and low-density manufacturing method is adopted in order to reduce the quality of the poster frame, and at the same time, the design of the umbrella pole is modeled, so that the height of each pole can be adjusted according to the size of the poster. Length, so as to realize the adaptability to posters of different sizes, and at the same time, each rod can be retracted when not in use, so as to achieve the purpose of reducing the occupied space;

The column 2 plays the role of supporting the poster frame 1 and connecting the load-bearing block 3, and the column can rotate in the center hole of the load-bearing block 3.

The weight block 3 is used to increase the weight of the bottom so that the center of gravity of the whole structure is lowered so that the poster frame is not easy to fall. The load-bearing block 3 can be self-contained, or it can be a cavity for placing the load-bearing block. When in use, the load-bearing block is put into it, and the load-bearing block is taken out when not in use, thereby greatly reducing the weight of the poster frame mechanism, thereby facilitating handling and transportation.

The shape of the bottom surface of the tripod 4 is the outline surface of a tumbler, and the four-branched tripod is used to avoid the entire curved surface of the tumbler and save materials.

The fixed rod 5 is used to fix the relative position of the tripod 4 with respect to the side of the weight block 3, and one end of the fixed rod 1 is fixed on the base of the side of the weight block 3 or on the side of the weight block 3, and the other end is connected to the side of the tripod 4. A pin rod cooperates and fastens. When not in use, the fixing rod can be lifted up, and then the tripod 4 can be folded to reduce the occupied space.
