Description

Technical Field

[0001] This invention relates to the field of engineering drawing tools, specifically a storage device for drawing tools used in engineering cost budgeting. Background Technology

[0002] Construction cost refers to the total cost of completing a construction project, covering the financial investment from the initial planning to the final acceptance. It is a core aspect of construction management, directly affecting the economic benefits and feasibility of the project. The total cost of construction costs includes investment estimates, design budgets, construction drawing budgets, and final settlements. The calculation method for construction cost requires drawing, and drawing tools are usually stored in a toolbox.

[0003] Based on the above findings of the inventors, the existing main shortcomings are as follows: the current drawing toolboxes need to be carried by hand, and the weight of the drawing toolboxes is relatively large. Carrying them for a long time will cause arm pain. In addition, the toolboxes can only be used as storage for drawing tools, and their function is limited. When measuring and drawing in construction, the drawings do not have a panel for support, which will affect the effect of the engineering cost drawing and lead to errors in the engineering cost budget. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing drawing toolboxes, which require carrying by hand, are heavy, and cause arm pain after prolonged carrying. Furthermore, the toolboxes can only be used for storing drawing tools, which is a single function. When conducting measurement and drawing in construction, the lack of a support panel on the drawings affects the quality of the engineering cost drawing and leads to errors in the engineering cost budget. Therefore, this invention proposes a storage device for drawing tools used in engineering cost budgeting.

[0005] To address the above problems, the present invention provides a storage device for drawing tools used in engineering cost budgeting.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a storage device for drawing tools for engineering cost budgeting, the structure of which includes a box, the top of the box being rotatably connected to a top cover, the top of the top cover being provided with three tool boxes, and drawing pen boxes being provided on both sides of the box. The interior of the box is provided with a sliding groove, and slide rails are provided on both sides of the sliding groove. The two slide rails slide in conjunction with the box. The rear bottom of the box is provided with two mounting grooves, and pulleys are provided in the two mounting grooves respectively. The pulleys can be rotated to adjust the direction.

[0007] Furthermore, the interior of the suitcase is provided with three small storage slots and one large storage slot. Both sides of the suitcase have inner slots, and the rear ends of the two inner slots are fixedly connected to the lifting handle.

[0008] Furthermore, the lifting handle includes two telescopic tubes fixedly installed at the rear ends of the two inner grooves, the end faces of the two telescopic tubes are fixedly connected to two connecting tubes, and the two connecting tubes are fixedly connected to the handle tube.

[0009] Furthermore, the box also includes four support structures at the bottom, which are fixedly installed on the four sides of the bottom of the box, and the bottom of the box is also provided with two fixing straps.

[0010] Furthermore, the fixing straps securely install the two support structures together.

[0011] Furthermore, the support structure includes a support base fixed to the bottom of the box, the support base being rotatably connected to the telescopic rod, the telescopic rod being movably engaged with the support tube, and a fixed guide ring being provided at the end of the support tube, the fixed guide ring being threadedly engaged with the end face of the support tube.

[0012] Furthermore, a cross groove is provided at the top of the support tube, and the outer surface of the support tube at the lower end of the cross groove is threaded, and a rubber foot pad is provided at the bottom of the support tube.

[0013] Furthermore, the end face of the fixed guide ring is tapered, and the tapered end face of the fixed guide ring can compress the support tube and deform it inward through the cross groove to clamp the telescopic rod. Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes the pulleys on both sides of the rear end of the box to flip down and contact the ground. Then, by pulling the handle tube, two telescopic tubes are extended outward, allowing the staff to move the box by pulling it, making it convenient to carry the storage device for drawing tools.

[0015] 2. This invention utilizes the flip-top cover and the top of the box to form a platform, and then pulls the box outward to take out drawing tools and drawings from the large and small storage slots and place them on the platform for engineering cost drawing.

[0016] 3. This invention utilizes the telescopic rods in the four support structures to flip downwards and lock into the end face of the support base. The length of the support tube is then adjusted by pulling it downwards, so that the telescopic rods support the bottom of the box. At the same time, the length of the support tube extending outwards can be adjusted according to the height of the staff, so that the staff can draw in a comfortable posture on the end face of the box.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] Example 1: Please refer to Figures 1-5 The specific embodiments of the present invention are as follows: Its structure includes a box body 1, the top of which is rotatably connected to a top cover 4, the top of which is provided with three tool boxes 2, and drawing pen boxes 3 are provided on both sides of the box body 1. The interior of the box body 1 is provided with a sliding groove 11, and the two sides of the sliding groove 11 are respectively provided with slide rails 12. The two slide rails 12 are slidably engaged with the pull-out box 13. The bottom of the rear end of the box body 1 is provided with two mounting grooves 14, and the two mounting grooves 14 are respectively provided with pulleys 15. The pulleys 15 can be rotated to adjust the direction. By flipping the top cover 4 outward by 180 degrees, the top of the box 1 can be connected to the top cover 4 to form a platform, allowing staff to place drawings on the top for engineering cost budgeting, which improves the convenience of drawing in construction projects. The pull box 13 can hold drawing tools and drawings, and the pull box 13 is supported by two slide rails 12 to be pulled outward, which facilitates the storage of drawing tools during the drawing process.

[0027] The interior of the pull-out box 13 is provided with three small storage slots 132 and one large storage slot 131. Both sides of the pull-out box 13 are provided with inner slots 133, and the rear ends of the two inner slots 133 are respectively fixedly connected to the lifting handle 134. The drawing tools are stored in the small storage compartment 132, and the engineering drawings are stored in the large storage compartment 131, which facilitates the storage of the drawing tools and drawings.

[0028] The lifting handle 134 includes two telescopic tubes 1341 fixedly installed at the rear ends of two inner grooves 133. The end faces of the two telescopic tubes 1341 are fixedly connected to two connecting tubes 1342, and the two connecting tubes 1342 are fixedly connected to the handle tube 1343.

[0029] Based on the above embodiments, the specific working principle is as follows: the four support structures 5 are flipped down to adjust their length and provide stable support to the bottom of the box 1. Then, the top cover 41 is flipped down to form a platform with the top of the box 1. Then, the drawing tools and drawings are taken out from the large storage slot 131 and the small storage slot 132 by pulling the box outward and placing them on the platform for engineering cost drawing. After the meeting is completed, the pull-out box 13 can be pushed back into the inner groove 133 and fixed by the buckles at both ends of the outer side of the inner groove 133 to prevent the pull-out box 13 from moving outward during transportation. The top cover 4 can be flipped to fit together with the top of the box body 1 and fixed by the two buckles at the front end of the box body 1. Then, the pulleys 15 on both sides of the rear end of the box body 1 can be flipped down to contact the ground. Then, by pulling the handle tube 1343, the two telescopic tubes 1341 can be extended outward, so that the staff can pull the box body 1 to move it, which is convenient for carrying the drawing tool storage device.

[0030] Example 2: Please refer to Figures 6-7 The specific embodiments of the present invention are as follows: The box body 1 also includes four support structures 5 at the bottom, the support structures 5 are fixedly installed on the four sides of the bottom of the box body 1, and the bottom of the box body 1 is also provided with two fixing straps 6. The two supporting structures 5 are secured by two fixing straps 6, making it easy to carry the box 1.

[0031] The fixing straps 6 securely install the two supporting structures 5 together.

[0032] The support structure 5 includes a support base 54 fixed to the bottom of the box 1. The support base 54 is rotatably connected to the telescopic rod 52. The telescopic rod 52 is movably engaged with the support tube 51. The end of the support tube 51 is provided with a fixed guide ring 53, which is threadedly engaged with the end face of the support tube 51. The telescopic rods 52 in the four sets of support structures 5 rotate downwards, and the support tubes 51 extend to the end of the telescopic rods 52, so that the bottom of the support tubes 51 can be supported on the ground. Then, the rotating and fixing guide rings 53 squeeze the end face of the support tubes 51 to deform inwards, increasing the friction between the support tubes 51 and the telescopic rods 52, fixing the length of the support tubes 51, and providing stable support for the bottom of the box 1.

[0033] The top of the support tube 51 is provided with a cross groove 512, the lower end of the cross groove 512 is provided with a thread 511 on the outer surface of the support tube 51, and the bottom of the support tube 51 is provided with a rubber foot pad 513. By providing a cross groove 512 at the top of the support tube 51, the top end of the support tube 51 can be deformed by compression.

[0034] The end face of the fixed guide ring 53 is tapered. The tapered end face of the fixed guide ring 53 can compress the support tube 51 and deform it inward through the cross groove 512 to clamp the telescopic rod 52.

[0035] Based on the above embodiments, the specific working principle is as follows: The bottom of the box 1 is supported by the support structure 5. The telescopic rods 52 in the four support structures 5 can be flipped down and locked onto the end face of the support base 54. Then, the length of the support tube 51 is adjusted by pulling it down, so that the telescopic rods 52 support the bottom of the box 1 horizontally. Then, by rotating the fixed guide ring 53 and engaging with the thread 511 on the end face of the support tube 51, the tapered end face of the fixed guide ring 53 is squeezed into the cross groove 512, which increases the friction between the support tube 51 and the telescopic rod 52, preventing the support tube 51 from retracting into the telescopic rod 52, improving the stability of the support for the box 1, and allowing the staff to draw engineering cost drawings on the platform formed by the support of the box 1 and the top cover 4. The support structure 5 can be folded and rotated at the bottom of the box 1 and fixed by the fixing strap 6.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
