As shown in fig. 1 to 5, the drawing display device provided by the utility model mainly comprises a support plate 1, a display plate 2 and a support assembly 3. Specifically, the support assembly 3 is composed of two support arms 31, a support bar 32 and a plug-in bar 33.

One end of each support arm 31 is hinged to the surface of the support plate 1, and the other end is hinged to the support assembly 3. The first surface 311 of the support arm 31 is provided with a plurality of equally spaced slots 312. These slots 312 may be used to receive the support rods 32.

In addition, the second surface 313 of the support arm 31 is provided with a receptacle 314 for inserting the docking rod 33. Whereas the lower surface of the display board 2 is provided with a spacer 5.

In the actual use process, when the drawing showing device is folded (shown in figure 1), the drawing showing device is similar to a briefcase in shape and is convenient to carry. When the drawing sheet is to be displayed, the support plate 1 is first placed on the ground or other plane. The display board 2 is then lifted and the support arm 31 is dynamically adjusted to the proper position. When the display board 2 is lifted to an appropriate height, the support bar 32 is inserted into the card slot 312 so that the support bar 32 can stably support the support arm 31.

Next, the angle of display board 2 relative to support arm 31 may be adjusted as desired and docking rod 33 inserted into a different receptacle 314. At this time, the support for the display board 2 can be released, so that the cushion block 5 of the display board 2 is contacted with the insertion rod 33, and the display board 2 is in a stable state. And then, the engineering drawing to be displayed is paved on the display board 2, so that the engineering drawing can be conveniently displayed and checked. The utility model is simple and convenient to operate, and the utility model completely depends on the mechanical structure to realize the display of the drawing and the folding of the drawing, thereby having extremely high reliability. After the drawing is displayed, the display device is folded so as to be convenient to store and carry.

As an alternative embodiment, in order to enhance portability, the present utility model provides handles 4 on the support plate 1 and the display plate 2. Specifically, when the drawing sheet display apparatus is in a folded state (as shown in fig. 1), the two handles 4 correspond to each other. Thus, the user can easily carry the drawing presentation device by holding the two handles 4 like carrying briefcases. The design ensures that the device has great convenience in moving and carrying, and the application flexibility of the device in various construction sites is obviously improved.

As an alternative embodiment, the support bar 32 is designed as a bar body of a rectangular closed loop formed by bending. This structural design allows the support bar 32 to provide stable support while increasing the strength and durability of the structure, thereby improving the overall stability and service life of the drawing display device.

As an alternative embodiment, the clamping groove 312 is designed as a circular tube structure with an opening. When the support bar 32 is positioned in the clamping groove 312, the clamping groove 312 partially surrounds the support bar 32, thereby realizing stable support.

Specifically, when the display device needs to be unfolded, the support bar 32 is lifted first, so that the side of the support bar 32 away from the support plate 1 corresponds to the opening of the clamping groove 312. Subsequently, the support bar 32 is pushed into the card slot 312. During this process, the openings of the slots 312 undergo a slight elastic deformation to accommodate and receive the support rods 32. When the support bar 32 completely enters the clamping groove 312, the clamping groove 312 partially surrounds the support bar 32, thereby realizing stable support.

The design not only simplifies the operation process, but also enhances the supporting stability, and simultaneously utilizes the elastic deformation of the clamping groove 312, so that the supporting rod 32 can be more tightly matched with the clamping groove 312, and the stability of the display device is further improved. The supporting arm 31 may be, but not limited to, plastic, and the clamping groove 312 and the supporting arm 31 are integrally formed, and the plastic has the characteristics of light weight and easy manufacturing.

As an alternative embodiment, the surface of the display board 2 is made of a magnetic metal plate, such as iron, cobalt, nickel or alloys thereof, which have good magnetic properties. At least one magnet 6 is attached to the surface of the display board 2.

Specifically, when the engineering drawing needs to be displayed on the surface of the display board 2 (refer to fig. 1 and 5), the engineering drawing is first tiled on the surface of the display board 2. In this example, the number of magnets 6 is two and they are placed at the corners of the drawing sheet. Because magnet 6 can adsorb the surface at magnetic metal plate, consequently engineering drawing is fixed between magnet 6 and show board 2, has ensured the stability of drawing in the show in-process.

The design utilizes the adsorption force between the magnetic metal and the magnet, so that the fixing mode of the drawing is simplified, the display effect of the drawing is ensured, and the convenience and the efficiency of operation are greatly improved.

As an alternative embodiment, display board 2 comprises a board body 21, two movable boards 22, a guide bar 23, two racks 24 and a gear 25; the plate body 21 is internally provided with a transmission cavity 211 and a sliding cavity 212. The gear 25 is provided inside the transmission chamber 211 and is rotatable. The guide rod 23 is slidably mounted within the sliding chamber 212. Two movable plates 22 are respectively installed at both sides of the plate body 21 and are respectively fixedly connected with one end of a guide rod 23. The two racks 24 are fixedly connected with the two movable plates 22, respectively, and are meshed with the gears 25, respectively. The surface of the plate body 21 and the surface of the movable plate 22 are both magnetic metal plates, such as iron, cobalt, nickel or alloys thereof.

Specifically, in a normal state, the two movable plates 22 are attached to both sides of the plate body 21. When one of the movable plates 22 is pulled, it moves away from the plate body 21 and drives the guide rod 23 and the rack 24 to protrude from the inside of the plate body 21. This arrangement allows the guide rod 23 and the sliding chamber 212 to provide a good guide for the movement of the movable plate 22. During the movement of the rack 24, it drives the pinion 25 in rotation, which in turn moves the other rack 24 in the opposite direction. Thus, pulling one of the movable plates 22 can cause the two movable plates 22 to move away from the plate body 21 at the same speed.

Referring to fig. 5, in practical application, if the engineering drawing is longer, the movable plates 22 can be pulled to separate the two movable plates 22 from each other, then the engineering drawing is tiled on the surfaces of the two movable plates 22, and the engineering drawing is fixed in place by using the magnet 6. This design enables the display board 2 to accommodate drawings of different lengths, thereby improving the practicality of the drawing display device.

As an alternative embodiment, the end of the rack 24 remote from the movable plate 22 is provided with a stop 26. As shown in fig. 5, the limiting portion 26 is mainly designed to limit the moving distance of the movable plate 22. When the limit 26 contacts the gear 25, it indicates that the movable plate 22 has reached the maximum movement distance and cannot be pulled any further. The maximum length of the engineering drawing that can be displayed by the display device is also the length that is formed between the two movable plates 22 in this state.

As an alternative embodiment, the side of the support plate 1 is provided with at least one slot 11, and the marking pen 12 is inserted into the slot 11. This arrangement allows the marker pen 12 to be located where it is convenient for the operator to access, enhancing the utility of the display device. When referring to or displaying an engineering drawing, an engineer or designer may need to make notes or marks on the drawing, such as marking out parts that need special attention, or marking out parts that have been completed or need modification. These labels facilitate a clear and quick understanding and execution of design or engineering instructions on the drawings, as well as communication and collaboration among team members. Therefore, the marking pen 12 and the display device are integrated together, so that the working efficiency can be improved, and the inconvenience caused by the fact that a marking tool cannot be found can be avoided.

In particular, the utility model is mainly used for displaying and consulting engineering drawings, and in the field of practical application, the engineering drawings are large in size and size, and certain difficulties exist in carrying and consulting. For example, in an engineering construction site, engineers need to frequently watch drawings, and the existing drawing display device is large in size and inconvenient to carry, and if the workers only hold the drawings with hands, the drawing display device is very inconvenient. In addition, the information on the engineering drawing is complex, and frequent labeling and annotation are required, which is often not considered by the existing display device.

The drawing display device provided by the utility model provides an effective solution to the problems. For example, it is portable and can be conveniently folded and carried; the display area can be adjusted according to the size of the drawing; meanwhile, the drawing annotating device is also provided with an annotating pen, so that a user can conveniently annotate and annotate the drawing. Therefore, the technical scheme of the utility model is highly relevant to the actual situation of the application field, and can effectively solve the technical problem in the actual application.

Although the main application scene of the utility model is to show engineering drawings, the design and implementation of the utility model have high universality and adaptability. In particular, the display device can be widely applied to various scenes needing to display large-scale paper data. For example, it may be used to present various paintings, whether in schools, museums, or public activities. The display area can be adjusted according to the requirement, and the display objects can be stably fixed, so that the display area is very suitable for displaying large-size paintings. At the same time, its portability also allows it to be conveniently carried and deployed, whether indoors or outdoors. In addition, the display device can be used for displaying various large-size maps, posters, advertisements and the like.

Therefore, although the present utility model is shown in the engineering drawings as a main application scenario, its application scope is not limited thereto. The high universality and the adaptability of the paper document display device can be widely applied to various scenes needing to display large-size paper documents.

The exemplary embodiments of the present application may be combined with each other, and exemplary embodiments obtained by combining also fall within the scope of the present application.

The present application has been described with particular application to the principles and embodiments thereof, the description of the above examples being only for aiding in the understanding of the method of the present application and its core ideas; meanwhile, those skilled in the art will have variations in the specific embodiments and application scope in light of the ideas of the present application, and the present description should not be construed as limiting the present application in view of the above.
