Description

Technical Field

[0001] The utility model relates to the field of drawing storage, in particular to a drawing storage device for highway cost estimation. Background Art

[0002] Highway cost estimation drawings are professional drawings used for cost estimation and budget preparation in highway construction projects. Such drawings contain key information about highway construction projects, aiming to help cost engineers accurately calculate various project costs and ensure that the budget is reasonable and meets actual construction requirements. In highway construction projects, engineers need to use storage devices to carry construction drawings for easy reference at the construction site.

[0003] When carrying construction drawings, multi-slot drawing cylinders are commonly used. Engineers roll up the construction drawings and store them in multiple placement slots inside the drawing cylinder and carry them with them. However, when it is necessary to retrieve the construction drawings, since the placement slots of the drawing cylinder are relatively deep, it is necessary to insert fingers into the placement slots to take out the construction drawings. This method is likely to rub or scratch the fingers, causing discomfort, or to flip the drawing cylinder to pour out the construction drawings from the placement slots. This method is likely to cause other construction drawings to pour out together, not only resulting in the mixing of construction drawings, but also possibly causing the order of the construction drawings to be disordered, increasing the time and difficulty of finding the construction drawings.

[0004] Therefore, there is a particular need for a drawing storage device for highway cost estimation to solve the above problems. Content of the Utility Model

[0005] In order to overcome the drawback that the placement slots of the drawing cylinder are relatively deep and it is inconvenient to retrieve construction drawings, the utility model provides a drawing storage device for highway cost estimation.

[0006] The utility model is achieved through the following technical means: A drawing storage device for highway cost estimation includes a base, a storage cylinder, a cylinder cover, a rotating shaft and a torsion spring. The lower part of the outside of the storage cylinder is fixedly connected with a base in a circular ring structure. The upper part of the outside of the storage cylinder is rotatably connected with a rotating shaft. A cylinder cover is fixedly connected to the rotating shaft and covers the upper part of the outside of the storage cylinder. Torsion springs are sleeved on both the left and right ends of the rotating shaft, and the two ends of the torsion spring are respectively connected with the storage cylinder and the cylinder cover. A locking component is arranged between the cylinder cover and the storage cylinder. A plurality of placement slots of different sizes are opened inside the storage cylinder. A pushing component is also included, and a pushing component for pushing out construction drawings is arranged inside the storage cylinder.

[0007] Furthermore, the pushing component includes a large gear, a small gear, a lead screw and a moving plate. A large gear and two small gears are rotatably connected to the lower part inside the storage cylinder, and the two small gears are respectively located on the left and right sides of the large gear and mesh with it. A lead screw is fixedly connected inside the small gear, and the upper end of the lead screw is rotatably connected to the upper part inside the storage cylinder. A moving plate is threadedly connected between the two lead screws.

[0008] Furthermore, the locking assembly includes a limiting block, a wedge-shaped clamping block, Spring I, a button, a connecting rod, a push plate, and Spring II. The front side of the upper part outside the storage cylinder is fixedly connected with the limiting block. The front side of the center inside the cylinder cover is slidably connected with the wedge-shaped clamping block. The wedge-shaped clamping block is clamped with the limiting block, so that the cylinder cover is fixed to the upper part outside the storage cylinder. Symmetrically distributed Spring I is connected between the wedge-shaped clamping block and the cylinder cover. The upper part inside the limiting block is slidably connected with the button. The rear side of the button is fixedly connected with the left-and-right distributed connecting rods. The connecting rods are slidably connected with the limiting block. A push plate is fixedly connected between the rear ends of the two connecting rods. The push plate slides inside the limiting block and is located in front of the wedge-shaped clamping block. A Spring II for assisting in resetting is sleeved outside the connecting rod. The two ends of Spring II are respectively connected with the button and the limiting block.

[0009] Furthermore, it further includes a handle. The outside of the storage cylinder is fixedly connected with the left-and-right distributed handles.

[0010] Furthermore, it further includes a transparent plate. A circular transparent plate for viewing the internal situation is embedded and connected inside the cylinder cover.

[0011] Furthermore, it further includes a label slot. The upper part inside the placement slot is fixedly connected with the label slot.

[0012] Furthermore, it further includes a knob. The center position of the bottom outside the storage cylinder is rotatably connected with the knob, and the knob is fixedly connected with the large gear.

[0013] From the above description of the structure of the present invention, the design starting point, concept, and advantages of the present invention are as follows:

[0014] By providing a pushing assembly in the present invention, when the large gear is rotated clockwise to be in positive meshing with the small gear, the small gear drives the lead screw to rotate, driving the moving plate to move upward, and pushing out the construction drawings in the placement slot, thus facilitating engineers to take the required construction drawings and effectively solving the problem that it is inconvenient to access the construction drawings due to the relatively deep placement slot.

[0015] By providing a locking assembly in the present invention, when the cylinder cover is rotated downward to close the storage cylinder, Spring I returns to its original state accordingly, prompting the wedge-shaped clamping block to move forward and be clamped with the limiting block, realizing the locking of the cylinder cover, which can ensure that the cylinder cover will not be easily opened in the closed state and guarantee the safe storage of the construction drawings.

A locking component is provided between the cylinder cover 4 and the storage cylinder 2. A plurality of placement slots 14 of different sizes are provided inside the storage cylinder 2 for storing construction drawings of different sizes. The transparent plate 5 is directly above all the placement slots 14. A label slot 15 is connected to the upper part inside the placement slot 14 by adhesion for placing label paper with construction drawing information, and the label slot 15 is a hidden design to ensure that the construction drawing is not blocked by the label slot 15 when it is pushed out. It also includes a pushing component, and a pushing component for pushing out the construction drawing is provided inside the storage cylinder 2.

[0027] Refer to Figures 6 - 8 As shown in the figure, the pushing component includes a knob 16, a large gear 17, a small gear 18, a lead screw 19, and a moving plate 20. A large gear 17 and two small gears 18 are rotatably connected to the lower part inside the storage cylinder 2, and the two small gears 18 are respectively located on the left and right sides of the large gear 17 and mesh with it. The knob 16 is rotatably connected to the center position of the bottom outside the storage cylinder 2, and the knob 16 is fixedly connected to the large gear 17 to facilitate rotating the large gear 17. The lead screw 19 is connected to the inside of the small gear 18 by welding, and the upper end of the lead screw 19 is rotatably connected to the upper part inside the storage cylinder 2. A moving plate 20 is threadedly connected between the two lead screws 19, and the moving plate 20 is in full sliding contact with a plurality of placement slots 14 to ensure that the construction drawing is smoothly pushed out.

[0028] Refer to Figure 1 、 Figures 3 - 5As shown, the locking assembly includes a limit block 101, a wedge-shaped block 8, a spring I9, a button 10, a connecting rod 11, a push plate 12 and a spring II13. The front side of the upper outer part of the storage cylinder 2 is connected to the limit block 101 by welding, and the wedge-shaped block 8 is slidably connected to the center of the front side of the cylinder cover 4. The wedge-shaped block 8 is engaged with the limit block 101, so that the cylinder cover 4 is fixed to the upper outer part of the storage cylinder 2, and the front side of the wedge-shaped block 8 is provided with an inclined surface. When contacting the limit block 101, it is first squeezed and moved backward and then engaged in the limit block 101. The wedge-shaped block 8 and the cylinder cover 4 are connected with springs I9 which are symmetrically distributed, a button 10 is slidably connected to the upper part of the limit block 101, and the rear side of the button 10 is connected with connecting rods 11 which are distributed on the left and right sides by welding, the connecting rods 11 are slidably connected to the limit block 101, and a push plate 12 is connected between the rear ends of the two connecting rods 11 by welding, the push plate 12 slides inside the limit block 101 and is located in front of the wedge-shaped block 8, and a spring II 13 for auxiliary resetting is sleeved on the outside of the connecting rod 11, and the two ends of the spring II 13 are respectively connected to the button 10 and the limit block 101.

[0029] Initially, the torsion spring 7 is in a compressed state. When the device needs to be used to store construction drawings, the engineer first presses the button 10 to make the connecting rod 11 drive the push plate 12 to move backward, and the spring II 13 is compressed accordingly. The push plate 12 squeezes the wedge-shaped block 8 to move backward and disengage from the limit block 101, and the spring I 9 is compressed accordingly, thereby achieving the loosening of the cylinder cover 4. The torsion spring 7 then returns to its original shape, prompting the rotating shaft 6 to drive the cylinder cover 4 to rotate upward to open the storage cylinder 2. Then the button 10 is released, and the spring II 13 returns to its original shape, prompting the connecting rod 11 to drive the push plate 12 to move forward and reset, and put the sorted construction drawings into the placement slot 14, so that the construction drawings contact the movable plate 20. After putting them in, put the label paper with the construction drawing information into the label slot 15, and then turn the cylinder cover 4 downward to close the storage cylinder 2, and the torsion spring 7 is deformed accordingly. The spring Ⅰ9 then returns to its original state, prompting the wedge-shaped block 8 to move forward and engage with the limit block 101, thereby locking the tube cover 4. Finally, hold any handle 3 with your hand and carry the storage tube 2 to the construction site. When you need to take the construction drawings, repeat the above steps to open the storage tube 2, then pinch the knob 16 with your hand to rotate the large gear 17 clockwise to make it mesh with the small gear 18 in the positive direction, so that the small gear 18 drives the screw rod 19 to rotate, driving the movable plate 20 to move upward, and push out the construction drawings in the placement slot 14. After pushing them out, check the label paper, take the required construction drawings, and then rotate the large gear 17 counterclockwise to make it mesh with the small gear 18 in the opposite direction, so that the small gear 18 drives the screw rod 19 to reverse, driving the movable plate 20 to move downward and reset, so that the construction drawings are stored in the placement slot 14 again, and repeat the above steps to close the storage tube 2.
