Description

The movable support bracket of urban track traffic sand table

Technical field

The utility model relates to a kind of urban track traffic sand table, more precisely a kind of movable support bracket of urban track traffic sand table.

Background technique

In the urban track traffic operation management specialty of School of Economics and Business Management, often can use the urban track traffic sand table, be used for visually the student being carried out the guidance of urban transportation operation management.Yet existing urban track traffic sand table need to manually be carried, because its volume is larger, weight is also larger, operates very inconveniently, and dangerous, causes easily the damage of sand table.

The model utility content

The utility model mainly is to solve the existing technical problem of prior art, thereby provides a kind of simple in structure, and cost is lower, the movable support bracket of urban track traffic sand table easy to use.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of movable support bracket of urban track traffic sand table, described carrier comprises two supporting bars, a dunnage and two universal rolling wheels, described two supporting bars layout that is parallel to each other, one end of described supporting bar is provided with runner, the two ends of described dunnage are connected with the top of described supporting bar, and described two universal rolling wheels are connected with the bottom of described dunnage.

As the utility model preferred embodiment, described carrier also comprises one first suspension rod, one second suspension rod and a suspension hook, the bottom of described the first suspension rod is connected with the top of described dunnage, one end of described the second suspension rod and the top of described the first suspension rod are rotationally connected, and the other end of described suspension hook and described the second suspension rod is rotationally connected.

As the utility model preferred embodiment, described carrier also comprises a hydraulic lift, and the two ends of described hydraulic lift are connected with the middle part of described the first suspension rod and described the second suspension rod respectively.

As the utility model preferred embodiment, described carrier also comprises a U-shaped grab bar, described U-shaped grab bar and mutual vertical connection of the top of described dunnage.

Therefore the movable support bracket of urban track traffic sand table of the present utility model is simple in structure, easy to use, and the user can freely move it in the classroom, convenient teaching.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

It is a kind of simple in structure that the utility model provides, and cost is lower, the movable support bracket of urban track traffic sand table easy to use.

Such as Fig. 1, Fig. 3, shown in Figure 4, a kind of movable support bracket of urban track traffic sand table, this carrier comprises two supporting bars 1, a dunnage 2 and two universal rolling wheels 3, these two supporting bars 1 layout that is parallel to each other, one end of this supporting bar 1 is provided with runner 11, the two ends of this dunnage 2 are connected with the top of this supporting bar 1, and these two universal rolling wheels 3 are connected with the bottom of this dunnage 2.

Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this carrier also comprises one first suspension rod 4, one second suspension rod 5 and a suspension hook 7, the bottom of this first suspension rod 4 is connected with the top of this dunnage 2, one end of this second suspension rod 5 and the top of this first suspension rod 4 are rotationally connected, and this suspension hook 7 is rotationally connected with the other end of this second suspension rod 5.

Such as Fig. 1, Fig. 2, shown in Figure 4, this carrier also comprises a hydraulic lift 6, and the two ends of this hydraulic lift 6 are connected with the middle part of this first suspension rod 4 and this second suspension rod 5 respectively.

Such as Fig. 1, Fig. 3, shown in Figure 4, this carrier also comprises a U-shaped grab bar 8, this U-shaped grab bar 8 and mutual vertical connection of the top of this dunnage 2.

The movable support bracket of the urban track traffic sand table of this model utility simple in structure, easy to use, the user can freely move it in the classroom, convenient teaching.

Below only with a mode of execution mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to simultaneously external more function module, thereby expands to greatest extent its function.

The above only be embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
