Portable construction site drawing display device and use method

Abstract

The invention provides a portable construction site drawing display device and a use method, and relates to a drawing display device. The portable construction site drawing display device comprises an upper cylinder and a lower cylinder, wherein an upper inner cylinder is rotationally connected into the upper cylinder through a bearing, internal threads are arranged in the upper inner cylinder and meshed with the surface of a sliding block, a drawing display mechanism is connected to the sliding block and used for unfolding and displaying a drawing, a lower inner cylinder is rotatably connected in the lower cylinder through a bearing, internal threads are arranged in the lower inner cylinder and meshed with a ground guide cone, a transmission piece is connected between the upper inner cylinder and the lower inner cylinder, the transmission piece is connected with the upper inner cylinder and the lower inner cylinder, and the transmission piece is rotated to drive the sliding block in the upper inner cylinder to move up and down and drive the ground guide cone in the lower inner cylinder to move up and down. According to the portable construction site drawing display device and the use method, the drawing is stored in the upper cylinder, the upper cylinder and the lower cylinder are connected with the transmission piece, the transmission piece rotates, the drawing display mechanism in the upper cylinder ascends, and the ground guide cone in the lower cylinder descends, so that the device is fixed, the drawing is displayed, and the portable construction site drawing display device is portable to carry and convenient to store.

Description

technical field [0001] The invention relates to the field of drawing display, in particular to a portable display device for construction site drawings and a use method. Background technique [0002] At present, the construction site needs to refer to a large number of construction drawings, and the size of the drawings is generally too large to be read and displayed by hand. Therefore, the construction site usually needs to purchase a construction drawing display device to display the drawings to improve construction efficiency. However, the existing drawing display devices are generally large in size and difficult to carry and fix. For example, the Chinese patent with the publication number CN205609153U and the publication date of 2016.09.28 discloses a bulletin board that is convenient for students to manage and use, including There are universal wheels, connecting support frames, sleeves, set screws, telescopic rods, promotional boards, etc. Although this device can be u...

However, the existing drawing display devices are generally large in size and difficult to carry and fix. For example, the Chinese patent with the publication number CN205609153U and the publication date of 2016.09.28 discloses a bulletin board that is convenient for students to manage and use, including There are universal wheels, connecting support frames, sleeves, set screws, telescopic rods, promotional boards, etc. Although this device can be used portablely through universal wheels, it is not suitable for moving on complex road conditions on the construction site, and it is difficult to Fixed on the changing ground environment and terrain, which will affect the display effect of construction drawings
