Technical Field
[0001] This utility model relates to the field of drawing display technology, and in particular to a hanging device for drawing display. Background Technology
[0002] An architectural elevation is an orthographic projection of a building, projected onto a vertical projection plane. An architectural section is an orthographic projection of a building, obtained by assuming a vertical cut along the building, based on the cutting position and projection direction indicated on the architectural plan. An architectural plan is a horizontal section obtained by imagining a horizontal cut above the windowsill, removing the top portion, and projecting the remaining portion as an orthographic view. Construction drawings, also known as "construction drawings," are drawings that represent the overall layout of a project, the building's external shape, internal arrangement, structural details, interior and exterior finishes, materials, equipment, and construction requirements.
[0003] When displaying drawings, hanging equipment is required. However, some existing drawing hanging equipment cannot automatically rewind the drawings, which means that manual rewinding is required, resulting in inconvenience.
[0004] To address the aforementioned issues, a hanging device for displaying drawings is proposed. Utility Model Content
[0005] The purpose of this invention is to at least solve one of the technical problems in the prior art that the drawings cannot be automatically rolled up effectively, and to provide a hanging device for displaying drawings that can solve the problems in the background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a suspension device for displaying drawings, comprising a fixed block, two support blocks fixedly installed at the bottom of the fixed block, the two support blocks having identical structures, a winding shaft rotatably connected inside the support block, a winding disc fixedly installed at one end of the winding shaft inside the support block, a pull rope wound on the surface of the winding disc, one end of the pull rope slidingly through the support block and extending to the outside of the support block, and a counterweight fixedly installed at one end of the pull rope.
[0007] Preferably, the counterweight has a sliding plate internally connected to it, and a connecting slide rod is fixedly installed on one side of the sliding plate.
[0008] Preferably, a clamping plate is fixedly installed at one end of the connecting slide rod that passes through the counterweight block.
[0009] Preferably, a return spring is movably sleeved on the connecting slide rod. The end of the return spring near the moving plate is fixedly connected to the moving plate, and the end of the return spring away from the moving plate is fixedly connected to the inside of the counterweight block. The winding shaft is also provided with a moving plate, a connecting slide rod, a return spring, and a clamping plate.
[0010] Preferably, two hooks are fixedly installed on the fixing block.
[0011] Preferably, a disc is fixedly sleeved on the winding shaft, and a torsion spring is movably sleeved on the surface of the winding shaft. The end of the torsion spring near the disc is fixedly connected to the disc, and the end of the torsion spring away from the disc is fixedly connected to the support block.
[0012] Preferably, a connecting block is fixedly installed on one side of the support block, and a sliding fixing rod is fixedly installed on one side of the counterweight block. The upper end of the sliding fixing rod is inclined, and the sliding fixing rod is slidably connected inside the connecting block.
[0013] Preferably, the connecting block has a sliding rod inside, and a tension spring is movably sleeved on the rod. The end of the tension spring near the connecting block is fixedly connected to the connecting block, and the end of the tension spring away from the connecting block is fixedly connected to the rod. A torsion spring is provided on the surface of the sliding fixed rod, and one end of the rod is slidably inserted into the torsion spring.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This suspension device for displaying drawings first rotates the winding shaft, causing the torsion spring to deform and thus fix the drawing to the winding shaft and counterweight. Then, the winding shaft is not rotated, allowing it to return to its original position through the torque of the torsion spring, thus winding the drawing onto the winding shaft. This facilitates the winding of the drawing, improving the convenience of drawing winding and transportation.
[0016] This suspension device for displaying drawings allows the connecting slide rod to move the movable plate inside the counterweight, thereby compressing the return spring and placing the drawing between the clamping plate and the counterweight. When the clamping plate is no longer pulled, it and the connecting slide rod return to their original positions due to the spring force, thus clamping the drawing. One end of the drawing is fixed to the winding shaft in the same way, thus securing the drawing and improving the ease of fixing it. Attached Figure Description

[0024] 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.
[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0026] Please see Figure 1-5 This utility model provides a technical solution: a suspension device for displaying drawings, including a fixed block 1, two support blocks 6 fixedly installed at the bottom of the fixed block 1, the two support blocks 6 having the same structure, a winding shaft 3 rotatably connected inside the support block 6, a winding disc 14 fixedly installed at one end of the winding shaft 3 inside the support block 6, a pull rope 11 wound on the surface of the winding disc 14, one end of the pull rope 11 slidingly passing through the support block 6 and extending to the outside of the support block 6, a counterweight block 4 fixedly installed at one end of the pull rope 11, a movable plate 16 slidably connected inside the counterweight block 4, a connecting slide rod 15 fixedly installed on one side of the movable plate 16, a clamping plate 5 fixedly installed at one end of the connecting slide rod 15 passing through the counterweight block 4, a return spring 17 movably sleeved on the connecting slide rod 15, the end of the return spring 17 near the movable plate 16 fixedly connected to the movable plate 16, and the end of the return spring 17 away from the movable plate 16 fixedly connected to the inside of the counterweight block 4, the winding shaft 3 also having a movable plate 16, a connecting slide rod 15, a return spring 17 and a clamping plate 5.
[0027] Pulling the clamping plate 5 causes the connecting slide rod 15 to slide the moving plate 16 inside the counterweight block 4, which in turn compresses the return spring 17, placing the drawing between the clamping plate 5 and the counterweight block 4. Then, the clamping plate 5 is no longer pulled, and the clamping plate 5 and the connecting slide rod 15 are reset by the elastic force of the return spring 17, thus clamping the drawing. One end of the drawing is fixed to the winding shaft 3 in the same way, thereby fixing the drawing and improving the convenience of fixing the drawing.
[0028] Two hooks 2 are fixedly installed on the fixing block 1.
[0029] The hook 2 makes it easy to hang the device at a designated location, thereby improving the convenience of hanging the device.
[0030] A disc 13 is fixedly sleeved on the winding shaft 3, and a torsion spring 12 is movably sleeved on the surface of the winding shaft 3. The end of the torsion spring 12 near the disc 13 is fixedly connected to the disc 13, and the end of the torsion spring 12 away from the disc 13 is fixedly connected to the support block 6.
[0031] When winding the drawing, first rotate the winding shaft 3, then deform the torsion spring 12, thereby fixing the drawing on the winding shaft 3 and the counterweight 4. Then stop rotating the winding shaft 3, and let the winding shaft 3 return to its original position through the torsion of the torsion spring 12, so that the drawing is wound on the winding shaft 3, which makes it easier to roll up the drawing, improves the convenience of rolling up the drawing, and facilitates the transportation of the drawing.
[0032] A connecting block 7 is fixedly installed on one side of the support block 6, and a sliding fixing rod 10 is fixedly installed on one side of the counterweight block 4. The upper end of the sliding fixing rod 10 is inclined. The sliding fixing rod 10 is slidably connected inside the connecting block 7. An insert rod 9 is slidably connected inside the connecting block 7. A tension spring 8 is movably sleeved on the insert rod 9. The end of the tension spring 8 near the connecting block 7 is fixedly connected to the connecting block 7, and the end of the tension spring 8 away from the connecting block 7 is fixedly connected to the insert rod 9. A torsion spring 12 is opened on the surface of the sliding fixing rod 10, and one end of the insert rod 9 is slidably inserted into the torsion spring 12.
[0033] When unfolding the drawing, pulling the insert rod 9 stretches the tension spring 8, causing the insert rod 9 to disengage from the inside of the torsion spring 12. This prevents the insert rod 9 from fixing the sliding fixed rod 10 and the counterweight 4. The weight of the counterweight 4 then pulls the drawing, causing the winding shaft 3 to rotate and the torsion spring 12 to deform. Simultaneously, as the winding shaft 3 rotates, the pull rope 11 is released, making it easier to unfold the drawing and improving the convenience of unfolding the drawing.
[0034] Working principle:
[0035] Pulling the clamping plate 5 causes the connecting slide rod 15 to slide the moving plate 16 inside the counterweight block 4, which in turn compresses the return spring 17, placing the drawing between the clamping plate 5 and the counterweight block 4. Then, the clamping plate 5 is no longer pulled, and the clamping plate 5 and the connecting slide rod 15 are reset by the elastic force of the return spring 17, thus clamping the drawing. One end of the drawing is fixed to the winding shaft 3 in the same way, thereby fixing the drawing.
[0036] First, rotate the winding shaft 3 to deform the torsion spring 12, thereby fixing the drawing on the winding shaft 3 and the counterweight 4. Then, stop rotating the winding shaft 3 and allow it to reset through the torque of the torsion spring 12, so that the drawing is wound on the winding shaft 3, making it easier to roll up the drawing.
[0037] When unfolding the drawing, pulling the insert rod 9 stretches the tension spring 8, causing the insert rod 9 to disengage from the inside of the torsion spring 12. This prevents the insert rod 9 from fixing the sliding fixed rod 10 and the counterweight 4. The drawing is then pulled by the weight of the counterweight 4, causing the winding shaft 3 to rotate and the torsion spring 12 to deform. At the same time, as the winding shaft 3 rotates, the pull rope 11 is unloaded, making it easier to unfold the drawing.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
