Description

Technical Field

[0001] This utility model relates to the field of drawing display scrolls, specifically a drawing display scroll for engineering cost estimation. Background Technology

[0002] Construction cost drawings are architectural or engineering design drawings that detail the quantities of each part of the project. Based on the quantities and market prices, the cost of the project is calculated. When not in use, they are usually rolled up and stored in a storage container.

[0003] In the existing technology, when engineering cost drawings are needed, the drawings need to be completely taken out of the storage tube and then unfolded. During the unfolding process, one person needs to pull the end of the drawing while another person unrolls it, which is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a scroll for displaying engineering cost drawings in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scroll for displaying engineering cost drawings, including a storage tube, one end of which is open, and a connecting cap is threaded to the open end of the storage tube. A sliding mechanism extending into the interior of the storage tube is provided on the outer periphery of the storage tube, and a winding mechanism is rotatably mounted on one end of the sliding mechanism. A clamping mechanism for clamping the top edge of the drawing is mounted on the winding mechanism.

[0007] As a further embodiment of this utility model: the winding mechanism includes a winding shaft rotatably connected to the center of the slide plate, and baffles are fixedly installed at both ends of the outer side of the winding shaft. The winding shaft located between the two baffles has a semi-cylindrical structure.

[0008] As a further embodiment of this utility model: the clamping mechanism includes a clamping plate that is connected to the top of the semi-cylindrical take-up shaft. The clamping plate has a planar structure at the joint position with the take-up shaft. Bolts are fixedly installed at both ends of the bottom of the clamping plate, and nuts are threaded onto the outer wall of the bolts.

[0009] As a further embodiment of this utility model: an anti-detachment plate is integrally formed at the end of the winding shaft away from the opening of the storage tube, and the diameter of the anti-detachment plate is larger than the diameter of the winding shaft.

[0010] As a further improvement of this utility model, two magnetic plates are fixedly installed on the outer periphery of the storage tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a magnetic suction plate and a winding mechanism, when it is necessary to unfold the drawing, the magnetic suction plate and the magnetic suction component are magnetically attracted to fix the storage tube. Then, the winding mechanism is pulled out, and a single person can rotate and unfold the drawing without the need for two people to operate, making it more convenient to use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this embodiment of the utility model, a drawing display scroll for engineering cost includes a storage tube 1. One end of the storage tube 1 is open. A connecting cap 4 is threadedly connected to the open end of the storage tube 1. A sliding mechanism extending into the storage tube 1 is provided on the outer periphery of the storage tube 1. A winding mechanism is rotatably installed on one end of the sliding mechanism. A clamping mechanism for clamping the top edge of the drawing is installed on the winding mechanism.

[0019] In this embodiment: when rewinding the engineering cost drawings, the top of the drawings is aligned with the clamping mechanism, and then the clamping mechanism is tightened to grip the top of the drawings. Then, the rewinding mechanism is rotated to rewind the drawings onto the rewinding mechanism. After rewinding is complete, the rewinding mechanism is pushed into the storage cylinder 1. After the rewinding mechanism is fully pushed in, the connecting cover 4 can be threaded onto the opening end of the storage cylinder 1 to prevent the rewinding mechanism from sliding outward.

[0020] When displaying the drawings, unscrew the connecting cover 4 and pull the winding mechanism out of the storage tube 1. At this time, the drawings can be unfolded and displayed for staff to view. In this way, the storage tube 1 can be kept separate from the winding mechanism, avoiding the problem of the storage tube 1 being lost.

[0021] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 The sliding mechanism includes a groove 2 formed on the outer wall of the storage tube 1, and a slide plate 5 extending through the inner cavity of the storage tube 1 on the outer periphery of the storage tube 1. The groove 2 and the slide plate 5 are slidably connected.

[0022] In this embodiment: when the drawing is pulled out, by pushing the portion of the slide plate 5 located on the outer periphery of the storage tube 1 to move, the slide plate 5 can move along the length direction of the storage tube 1. The moving slide plate 5 can push the winding mechanism to move outward until the winding mechanism drives the drawing to be completely moved out of the storage tube 1. At this time, the winding mechanism can be rotated to unfold the drawing.

[0023] Please refer to this carefully. Figure 2 and Figure 3 The winding mechanism includes a winding shaft 7 rotatably connected to the center of the slide plate 5. Both ends of the outer side of the winding shaft 7 are fixedly installed with baffles 8. The winding shaft 7 located between the two baffles 8 has a semi-cylindrical structure. The end of the winding shaft 7 away from the opening of the storage tube 1 is integrally formed with an anti-detachment plate 6. The diameter of the anti-detachment plate 6 is larger than the diameter of the winding shaft 7.

[0024] In this embodiment: when winding or unwinding the drawing, rotating one end of the winding shaft 7 will cause the drawing to rotate synchronously. Different directions of rotation will achieve winding and unwinding respectively.

[0025] Please refer to this carefully. Figure 3 The clamping mechanism includes a clamping plate 9 that is connected to the top of the semi-cylindrical take-up shaft 7. The clamping plate 9 has a planar structure at the joint position with the take-up shaft 7. Bolts are fixedly installed at both ends of the bottom of the clamping plate 9, and nuts are threaded on the outer wall of the bolts.

[0026] In this embodiment: when fixing the top of the drawing, the top edge of the drawing is placed between the top of the clamping plate 9 and the top of the semi-cylindrical part of the winding shaft 7, and then the nut is tightened on the outer wall of the bolt. At this time, the clamping plate 9 and the winding shaft 7 cooperate to clamp the top edge of the drawing. After clamping, the winding shaft 7 can be rotated to wind up the drawing.

[0027] Please refer to the diagram carefully. Two magnetic plates 3 are fixedly installed on the outer periphery of the storage tube 1.

[0028] In this embodiment: Before unfolding the drawing, the storage tube 1 is taken out of the waterproof packaging, and then the magnetic plate 3 is attached to the magnetic component. At this time, the position of the storage tube 1 is limited. Afterwards, when pulling out the winding mechanism, no additional operation is required to fix the drawing, making it more convenient to unfold and display.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
