Description

Technical Field

[0001] The utility model relates to the technical field of toolboxes, in particular to a budget toolbox for engineering cost management. Background Art

[0002] During work, construction project cost estimators often need to consult a large number of technical and economic materials and books to obtain various data, and always use drawing and calculation tools such as a ruler, an eraser, and a pencil. During the calculation process, various calculation formulas also need to be memorized. However, when using a writing pad for writing outdoors with the existing budget toolbox for engineering cost management, the box body may need to be placed on the ground. However, when the box body is placed on the ground, its height is relatively low, which is inconvenient for construction project cost estimators to write when using it.

[0003] The existing Chinese patent with the publication number of CN221542589U discloses a budget toolbox for engineering cost management, including a box body and a cover plate. A storage groove is opened at the inner top of the box body, and the cover plate is arranged above the box body; a hinge groove is opened at the bottom of one end of the cover plate, and a hinge block is hinged inside the hinge groove through a first pin shaft. One end of the hinge block extending out of the hinge groove is fixedly connected with a first support rod; a groove is opened at the top of the box body, and a second support rod is hinged inside the groove through a second pin shaft. The budget toolbox for engineering cost management of the utility model has a simple structure and is convenient to use. The cover plate and the box body are connected through the first support rod and the second support rod, and limit ball blocks and limit ball grooves for limit locking are arranged at the joints between the support rods and the cover plate and the box body, so that the cover plate can be flipped and adjusted after being opened. Until the first support rod and the second support rod are fully unfolded, the cover plate can be supported, enabling the staff to write on the cover plate.

[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: the device uses the cover plate as a writing table, and the size of the cover plate is limited by the box body and cannot be expanded according to the use requirements, and improvement is needed; therefore, a budget toolbox for engineering cost management is proposed for the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figures 1-4 As shown, a project cost management budget toolbox includes a box body 1 and a hinged box cover 2. A buckle is provided at the other end of the hinged part of the box body 1 and the box cover 2 for fixation. Extension plates 3 are respectively rotatably connected to both sides of the box cover 2 through damping rotating shafts. A writing assembly 4 is installed on the extension plates 3, the box body 1 and the box cover 2. The writing assembly 4 includes two U-shaped limit frames 41 and slide grooves 42. The limit frames 41 penetrate through the extension plates 3, and the slide grooves 42 are opened at one end of the extension plates 3 far from the box body 1. A connecting frame 43 is slidably connected inside the slide grooves 42, and both ends of the connecting frame 43 are fixedly connected to the limit frames 41. Card slots 6 are symmetrically opened on both sides of the box body 1. The box body 1 is used to place tools such as pens and papers required for project cost. When project cost budgeting is required, the top of the box cover 2 can be used for writing. By rotating the extension plates 3 upward and inserting the limit frames 41 into the card slots 6, the extension plates 3 can be kept horizontal to expand the writing range.

[0028] The side walls of the connecting frame 43 are symmetrically and fixedly connected with tension springs 44, and the other ends of the tension springs 44 are fixedly installed inside the slide grooves 42. When the limit frames 41 are inserted into the card slots 6, the limit frames 41 are tightly pressed against the card slots 6 through the tension springs 44, improving the connection stability between the extension plates 3 and the box cover 2. When it is necessary to remove the extension plates 3, pull the limit frames 41 out of the card slots 6 and then rotate the extension plates 3 downward for storage.

[0029] The writing assembly 4 further includes two U-shaped legs 45. The widths of the two legs 45 decrease from outside to inside, and the lengths of the two legs 45 are the same.

[0030] Both ends of the outrigger 45 are rotatably connected to a fixed seat 46 through damping rotating shafts, and the fixed seat 46 is fixedly installed at the bottom of the box body 1. The outrigger 45 is stored at the bottom of the box body 1 by damping force. By rotating and unfolding the outrigger 45 to abut against the ground, the height of the box cover 2 can be increased, improving the comfort during writing.

[0031] A limiting protrusion 47 is fixedly connected to the side wall of the fixed seat 46. The rotation angle of the outrigger 45 is limited by the limiting protrusion 47, so that the two outriggers 45 are distributed in a V-shaped manner to support the box body 1.

[0032] Embodiment 2

[0033] Comparing with Embodiment 1, please refer to Figure 5 As shown, the present utility model provides another implementation manner. A handle assembly 5 is installed above the box body 1. The handle assembly 5 includes two grips 51. One end of each grip 51 is fixedly connected with a first connecting rope 52 and a second connecting rope 53 respectively.

[0034] The end of the first connecting rope 52 away from the grip 51 is fixedly connected to the box body 1. The end of the second connecting rope 53 away from the grip 51 is fixedly connected with a clamping plate 54, and the clamping plate 54 is made of ferromagnetic material. By inserting the clamping plate 54 into the inside of the slot 57, the user can hold the grip 51 to move the toolbox. When writing is needed, the clamping plate 54 is taken out from the inside of the mounting seat 56 to prevent the handle assembly 5 from affecting the user's writing on the box cover 2.

[0035] A flexible sleeve 55 is fixedly connected to the surface of the grip 51, and the flexible sleeve 55 improves the comfort when holding the grip 51.

[0036] The handle assembly 5 further includes two mounting seats 56. A slot 57 is formed inside the mounting seat 56. A magnetic block is embedded in the side wall of the slot 57. The mounting seat 56 is fixedly installed on the side wall of the box body 1. The clamping plate 54 is adsorbed by the magnetic block, so that the clamping block is fixed in the slot 57.

[0037] Working principle: The box body 1 is used to place tools such as pens and papers required for engineering cost. When cost budgeting is needed, the top of the box cover 2 can be used for writing. By rotating the extension plate 3 upward and inserting the limiting frame 41 into the inside of the card slot 6, the extension plate 3 is kept horizontal to expand the writing range.

[0038] When the limiting frame 41 is inserted into the inside of the card slot 6, the limiting frame 41 tightly abuts against the card slot 6 through the tension spring 44, improving the connection stability between the extension plate 3 and the box cover 2. When the extension plate 3 needs to be removed, the limiting frame 41 is pulled out of the card slot 6, and then the extension plate 3 can be rotated downward and stored.

[0039] The outrigger 45 is retracted at the bottom of the box body 1 by damping force, and the height of the box cover 2 can be increased by rotating and unfolding the outrigger 45 to abut against the ground, thereby improving the comfort during writing.

[0040] By inserting the clamping plate 54 into the interior of the slot 57, the magnetic block adsorbs the clamping plate 54, so that the clamping block is fixed in the slot 57, enabling the user to hold the handle 51 and move the toolbox. When writing is required, the clamping plate 54 is taken out from the interior of the mounting seat 56 to prevent the handle assembly 5 from affecting the user's writing on the box cover 2.
