Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost drawing auxiliary tools, in particular to an engineering cost drawing display scroll. Background Art

[0002] Drawings of construction projects are key documents for construction and are also key information for investment units to evaluate costs. The content of the drawings about project costs includes not only the type, quantity and size of building materials in different construction locations, but also information such as the cost under different production plans.

[0003] Therefore, it is the responsibility of the construction unit and the operating unit to protect the integrity of architectural drawings.

[0004] In the prior art, in order to ensure the clarity of engineering cost drawings, the drawings are usually rolled up when they are stored to avoid damage to the drawings caused by wrinkles. However, after the drawings are rolled up and stored, they are easily rolled up due to the rolling marks when they are displayed. Other items are needed to flatten the drawings for easy display. However, after the display is completed, the rolling marks are flattened, which will cause the speed of rolling up the drawings to be reduced, and the drawings are easily damaged during rolling up, so it is difficult to effectively protect the drawings. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a drawing display scroll for engineering cost so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A drawing display scroll for engineering cost includes a connecting shaft, both ends of which are rotatably connected to positioning disks, and arc-shaped cover plates are provided on opposite sides of the two positioning disks. A storage shaft is rotatably installed in the middle of one of the positioning disks, and the outer surface of the storage shaft is connected to a drawing rack, storage chains are embedded on both sides of the drawing rack, and a fixed frame is provided at the upper end of the drawing rack.

[0008] Furthermore, a plurality of evenly distributed magnets are embedded in the planar ends of the two arc-shaped cover plates.

[0009] Furthermore, positioning rails are arranged on both sides of the upper end of the drawing rack, and an embedding groove for installing the storage chain is opened at the upper end of the positioning rails.

[0010] Furthermore, the storage chain includes a plurality of first movable parts and a plurality of second movable parts connected in sequence, the first movable part includes a first rotating shaft and two first mounting plates, the first mounting plates are fixed at both ends of the first rotating shaft, and the two sides of the first rotating shaft are rotatably connected to the groove wall of the embedded groove.

[0011] Furthermore, the second movable member includes a second rotating shaft and a second mounting plate, one end of the second mounting plate is fixed to the middle of the outer surface of the second rotating shaft, and the other end of the second mounting plate is sleeved on the middle of the first rotating shaft.

[0012] Furthermore, damping sleeves are provided in the middle of the first mounting plate and the second mounting plate.

[0013] In summary, the present invention includes at least one of the following beneficial technical effects:

[0014] 1. The engineering cost drawing display reel increases the rotational friction between the first movable part and the second movable part by setting a damping sleeve, so that the chain forms a rigid chain after the stretching is completed. After the drawing frame is fully stretched, the drawing frame is prevented from curling due to its own elasticity when it is unfolded, thereby facilitating the display of drawings;

[0015] 2. The engineering cost drawing display scroll has two arc-shaped cover plates that can be quickly interlocked with each other through the setting of magnets, which is used to fix the two arc-shaped cover plates and facilitate the unfolding of the two arc-shaped cover plates, so as to achieve the effect of quickly replacing the drawings on the drawing rack, and enable the device to be repeatedly used.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0023] Reference Figure 1-Figure 4 The utility model discloses a drawing display scroll for engineering cost, including a connecting shaft 1, both ends of the connecting shaft 1 are rotatably connected with positioning disks 2, and arc-shaped cover plates 3 are arranged on opposite sides of the two positioning disks 2. A storage shaft 4 is rotatably installed in the middle of one of the positioning disks 2, and a drawing frame 5 is connected to the outer surface of the storage shaft. Storage chains 6 are embedded on both sides of the drawing frame 5, and a fixed frame 7 is arranged on the upper end of the drawing frame 5.

[0024] In this embodiment, when in use, the drawings to be saved are placed on the upper end of the drawing rack 5, and the fixed frame 7 is clamped on the upper end of the drawing rack 5 to fix the drawings. Since the fixed frame 7 and the drawing rack 5 are both made of flexible transparent materials (such as polystyrene plastic, PE polyethylene and other highly transparent plastic materials), the drawings for display can be easily observed through the fixed frame 7. By setting the storage chain 6, the drawing rack 5 can be rolled up, and when flattened, the gravity of the chain can make the drawing rack 5 more flat, preventing the drawing rack 5 from curling up, making it difficult to observe the drawings, and by setting the connecting shaft 1 and the two positioning plates 2, the two arc-shaped cover plates 3 can be buckled with each other to form a larger barrel shape, which is used to protect the drawings and prevent the drawings from being compressed and deformed.

[0025] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a plurality of evenly distributed magnets 8 are embedded in the planar ends of the two arc-shaped cover plates 3 .

[0026] In this embodiment, the magnet 8 is provided to fix the two arc-shaped cover plates 3, so that the two arc-shaped cover plates 3 are easy to unfold and close, and it is easy to replace the drawings on the drawing rack 5, so that the device can be reused many times.

[0027] In a further preferred embodiment of the present invention, Figure 1-4As shown, positioning rails 51 are provided on both sides of the upper end of the drawing rack 5 , and an embedding groove 52 for installing the storage chain 6 is opened at the upper end of the positioning rails 51 .

A guide groove for installing the positioning guide rail 51 is provided at a position on the bottom side of the fixed frame 7 corresponding to the positioning guide rail 51. When in use, the drawing is placed in the middle of the drawing frame 5, and the fixed frame 7 is placed on the upper end of the drawing, and the guide groove and the positioning guide rail 51 are engaged with each other, thereby achieving the effect of enclosing and fixing the drawing.

[0030] In this embodiment, the storage chain 6 formed by sequentially connecting the first movable member 61 and the second movable member 62 allows the drawing rack 5 to be rolled up at the same speed on both sides when rolled up, thereby preventing the drawing rack 5 from deviating.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the second movable member 62 includes a second rotating shaft 621 and a second mounting piece 622 , one end of the second mounting piece 622 is fixed to the middle of the outer surface of the second rotating shaft 621 , and the other end of the second mounting piece 622 is sleeved on the middle of the first rotating shaft 611 .

[0034] In this embodiment, by setting the damping sleeve 9, the friction between the first mounting plate 612 and the second rotating shaft 621 is increased, so that the chain forms a rigid chain after stretching, so that the drawing rack 5 can be fully stretched, and the drawing rack 5 is prevented from curling due to its own elasticity when unfolded, thereby achieving the purpose of facilitating the display of drawings.

[0035] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
