Description

Technical Field

[0001] The present application relates to the field of display racks, and in particular to a display rack for drawings used in engineering cost. Background Art

[0002] During the cost assessment process at the construction site, cost engineers are required to perform calculations and comparisons with reference to architectural drawings at the construction site in order to derive the construction and construction costs of the corresponding buildings.

[0003] At present, when cost engineers use drawings at construction sites, they usually spread them out directly on the ground at the construction site. Since there are sharp objects such as stones on the ground at the construction site, the drawings are easily worn or even punctured during use. In addition, when encountering strong winds or rainy days, the drawings spread out on the ground are easily blown away or wetted, making the overall use of the drawings inconvenient. Therefore, there is room for improvement. Utility Model Content

[0004] In order to facilitate cost engineers to use drawings at construction sites while reducing the possibility of drawings being damaged, the present application provides a display stand for engineering cost drawings.

[0005] The present application provides a display stand for engineering cost drawings, which adopts the following technical solution:

[0007] By adopting the above technical solution, when cost engineers use drawings at the construction site, they can stick the architectural drawings on the drawing display board by adhesive tape, etc., so as to unfold the drawings through the drawing display stand. Compared with the traditional way of unfolding the drawings on the ground, the drawings are displayed on the drawing display stand to reduce the wear of the drawings by sharp debris such as stones on the ground during use. By setting the rain shield, the rain shield can be used to limit the contact of rainwater with the drawings on the drawing display board, thereby reducing the situation where the drawings on the drawing display board are wetted by rainwater when the drawings are used on rainy days; by setting a number of universal wheels at the bottom of the base, it is convenient to move the drawing display stand to a specified position according to actual needs; by setting the counterweight block, it is convenient to improve the overall stability of the base, so as to reduce the subsequent overturning of the drawing display stand due to external force.

[0008] Preferably, the bracket includes two telescopic rods arranged opposite to each other, the telescopic rod includes a support sleeve vertically connected to the base, a support rod is inserted into the support sleeve, a main limit bolt is threaded through the outer periphery of the support sleeve, one end of the main limit bolt is tightly set against the support rod; both ends of the drawing display board are respectively connected to the two support rods through a connecting assembly.

[0009] By adopting the above technical solution, the overall height of the drawing display board can be adjusted by adjusting the length of the telescopic rod, so that the cost engineer can adjust the height of the drawing display board according to actual needs during subsequent use, which is beneficial to improving the overall applicability of the drawing display stand.

[0010] Preferably, the connecting assembly includes a connecting pin horizontally connected to the end of the drawing display board, and the connecting assembly also includes a connecting sleeve connected to the support rod, the connecting pin is rotatably inserted into the connecting sleeve, and the outer periphery of the connecting sleeve is also threaded with a secondary limiting bolt, and one end of the secondary limiting bolt is tightly set against the outer periphery of the connecting pin.

[0012] Preferably, one side of the drawing display board is a display surface, and a transparent protective plate is detachably mounted on the display surface.

[0013] By adopting the above technical solution, after the drawings are adhered to the display surface of the drawing display board, the transparent protective plate is installed on the drawing display surface, and the transparent protective plate is used to wrap and protect the drawings, thereby further isolating rainwater or debris such as welding slag sparks at the construction site from contacting the drawings on the drawing display board, thereby facilitating the normal use of the drawings in harsh environments.

[0014] Preferably, a surface of the transparent protective plate close to the drawing display board is provided with a plurality of magnetic protrusions, and a plurality of magnetic grooves are provided on the display surface of the drawing display board corresponding to the plurality of magnetic protrusions, and the magnetic protrusions are inserted into and magnetically engaged with the corresponding magnetic grooves.

[0016] Preferably, a plurality of limiting sleeves are provided on the upper surface of the base corresponding to the plurality of counterweight blocks, and the counterweight blocks are inserted into the corresponding limiting sleeves.

[0017] By adopting the above technical solution, the counterweight block can be detachably connected to the base, so that the counterweight block does not need to be integrally formed with the base. When the drawing display stand is subsequently moved to a different position, the counterweight block can be removed from the base first to reduce the overall weight of the drawing display stand, thereby facilitating the overall movement of the drawing display stand.

[0018] Preferably, the base is provided with a plurality of through holes for inserting steel drills.

[0019] By adopting the above technical solution, when the drawing display stand is used on a soil ground, a steel chisel or other connector can be inserted into the through hole and driven into the ground to further limit the position of the drawing display stand and reduce the possibility of the drawing display stand tipping over due to external force during subsequent use.

[0020] Preferably, a plurality of LED light tubes are installed on the bottom side of the rain shield.

[0021] By adopting the above technical solution, the drawing display board and drawings on the bottom side of the rain shield can be illuminated by LED light tubes, making it convenient to use the drawing display stand in dim light or at night.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the cost engineer uses the drawings, he can unfold the drawings and stick them to the drawing display board with tape, so that the drawings can be placed on the drawing display board, which is convenient for the cost engineer to use the drawings at the construction site; by setting the rain shield on the top of the bracket, the rain shield is used to shield the drawing display board and the drawings glued to the drawing display board, so as to reduce the situation where rainwater contacts the drawings on rainy days and causes the drawings to be soaked and damaged.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a drawing display stand for engineering cost, referring to Figure 1 and Figure 2 , comprising a base 1, a bracket 2 and a drawing display board 3, wherein the bracket 2 is vertically supported on the base 1, and the drawing display board 3 is installed on the bracket 2. A rain shield 4 is also installed on the top of the bracket 2, and the rain shield 4 is located above the drawing display board 3, and the projection of the rain shield 4 on the horizontal plane covers the projection of the drawing display board 3 on the horizontal plane.

[0034] The drawings can be unfolded by sticking them on the drawing display board 3 with adhesive tape, which is convenient for cost engineers to use the drawings at the construction site, and there is no need to place the drawings on the ground, which reduces the risk of the drawings being easily damaged. The provision of the rain shield 4 facilitates shielding the drawings stuck on the drawing display board 3, so as to reduce the risk of the drawings being wetted by rainwater in subsequent rainy days.

[0035] A plurality of universal wheels 10 are installed at the bottom of the base 1, so that the drawing display stand can be flexibly moved to any area through the universal wheels 10 on the base 1. A plurality of counterweights 12 are installed on the base 1, so that the overall weight of the base 1 can be increased through the counterweights 12, thereby improving the overall stability of the drawing display stand and reducing the overturning of the drawing display stand in windy weather. In this embodiment, the counterweights 12 are all cylindrical steel blocks, and the outer periphery of the counterweights 12 is painted with anti-rust paint to reduce the counterweights 12 from rusting and damage.

[0036] The base 1 is welded with a plurality of limiting sleeves 11 corresponding to the plurality of counterweights 12. The bottom end of the counterweight 12 is inserted into the corresponding limiting sleeve 11, so that the counterweight 12 can be detachably mounted on the base 1. On the one hand, the counterweight 12 is reliably connected to the base 1. On the other hand, when the drawing display rack is subsequently moved, the counterweight 12 can be temporarily pulled out of the limiting sleeve 11 to facilitate the movement of the drawing display rack. A gripping ring 121 is welded on the top of each counterweight 12 to facilitate the movement of the counterweight 12 through the gripping ring 121.

[0037] The base 1 is also provided with a plurality of through holes 13 for inserting steel chisels. When the blueprint display stand is used on a muddy ground, the steel chisel can be inserted into the through holes 13 and driven into the ground to further limit the position of the base 1, thereby further limiting the overturning of the blueprint display stand due to external forces.
