Description

Landscape sand table

Technical Field

The utility model relates to a show apparatus field, concretely relates to landscape sand table.

Background

The garden sand table is in an intuitive, three-dimensional and three-dimensional expression form, is greatly different from a two-dimensional plane garden scheme or a construction drawing, is made of a material object into a three-dimensional model, visually displays the concept, function, form and structure of garden landscape design, and has super-strong three-dimensional space expression. The garden sand table adopts a miniature form, vividly shows gardens, and transmits and expresses garden design ideas in a unique form.

Because gardens sand table is generally used for carrying out the show of view in the gardens for the visitor in advance, consequently the size of sand table is generally great in order to improve the bandwagon effect for the sand table is difficult for the immigration indoor after the preparation is accomplished, and it is indoor to need the manpower to be in the sand table behind slope or the vertical state usually, operates inconvenient and hard. Meanwhile, if the sand table is directly manufactured at the placing position of the sand table, the placing place is easily messy, and the placing position of the sand table is usually the position necessary for visitors, so that the viewing experience of visitors is easily influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a convenient to use just does benefit to the landscape sand table of removal and transportation.

The utility model provides a technical scheme that above-mentioned problem adopted is:

the utility model provides a landscape sand table, includes the carriage and is used for the platform that the model was put, the both sides of the bottom of platform rotate with the limit post of the both sides of carriage respectively and are connected, and the both sides of the bottom of platform are slided by external drive and are set up in the sliding tray of limit post, the central point of the both sides of platform all realizes being connected with articulated mode through the connecting rod with the both ends at the top of carriage, and when not using, platform and carriage are located the coplanar, are 90 contained angles during the use between platform and the carriage.

As the further improvement of the technical scheme, the bottom of the platform is rotatably arranged on the side columns by the two sides of the bottom of the platform through the sliding blocks, the sliding blocks are rotatably connected with the platform, and the supporting frame is provided with a first driving module for driving the sliding blocks to move linearly. During the use, through the bottom rectilinear movement of sliding block rectilinear movement drive platform, because all articulated between the central point of the both sides of platform and the both ends at the top of carriage have the connecting rod for at the bottom rectilinear movement's of platform in-process, the platform takes place to rotate under the effect of connecting rod, thereby reaches the purpose that the platform becomes the expansion state by the folded state.

As a further improvement of the technical scheme, a supporting piece is arranged on the platform in a rotating mode and is of a telescopic structure, the supporting piece comprises a rotating piece and a sliding piece, one end of the rotating piece is hinged to the platform, the sliding piece is connected to the other end of the rotating piece in a sliding mode, and a second driving module used for driving the sliding piece to move linearly is arranged on the rotating piece. The telescopic structure of the supporting piece is beneficial to reducing the size of the device, and the device is convenient to move and transport.

As a further improvement of the technical scheme, the sliding block is cylindrical, and a rod groove for accommodating the connecting rod is formed in the sliding block.

As a further improvement of the technical scheme, the limit holes used for limiting the rotation of the connecting rods are formed in the side columns, so that the included angle between the control platform and the supporting frame when the control platform and the supporting frame are used is facilitated, and the phenomenon that the model is shifted or toppled due to the fact that the platform inclines is avoided.

Compared with the prior art, the utility model, have following advantage and effect:

the utility model discloses a deformation structure between platform and the carriage does benefit to the device and draws in the back and get into indoorly, has avoided because the too big indoor condition of unable entering of size under the sand table display state, convenient to use and reduction work degree of difficulty. Simultaneously, because the platform can switch between the state of expanding and drawing in, reduced the degree of difficulty of removal and transportation, and sand table maker can be in advance with the fixed sand table that will make the completion on the show position of sand table is taken to the sand table after placing the model on the platform directly in, avoided carrying out sand table at the show position of sand table and made the problem that leads to the place in disorder.
