Description

Technical Field

[0001] The utility model relates to the technical field of project management, in particular to a file storage box for project management. Background Art

[0002] When multiple engineering projects are being constructed at the same time, a project management file storage box is set up to facilitate the staff to separately store different project materials, and to facilitate the staff to store the completed project materials and avoid confusion of materials.

[0003] During the use of existing devices, the storage part cannot be automatically restored, and some of the automatic reset devices need to use electronic control equipment to work during use, which increases the difficulty of installing the electronic control equipment and the potential safety hazards. In addition, when some existing devices are used, there is a collision between the box and the cabinet, which leads to damage after use. Utility Model Content

[0004] The purpose of the utility model is to provide a file storage box for project management, which is used to overcome the above-mentioned defects in the prior art.

[0005] The foldable drawer is a kind of file storage box for project management of the utility model, comprising an outer box, wherein the outer box is provided with drawers that can slide back and forth and are evenly distributed, and a handle is fixed on the front surface of the drawer, and the left and right ends of the outer box are fixed with two guide slides distributed up and down, and the rear end of each guide slide is fixed with a limit block, and a card slot is opened in the front end of each limit block away from the drawer end. The outer box and the front end part of the four limit blocks are fixed with a card block, and the card block can be elastically engaged with the side wall of the card slot, and the outer box and the left and right ends of the drawer are fixedly connected with two fixed wire drums, and a fixed disk is provided between two adjacent fixed wire drums, and the fixed disk is fixedly connected to the outer box by a fixing rod, and a torsion spring rod is fixed on the fixed disk, and the torsion spring rod extends left and right and passes through the two adjacent fixed wire drums, and a rotating disk that can rotate is provided in the fixed wire drum. The cam is provided with a plurality of springs, each of which is connected to a pair of cams, and the plurality of cams have respective springs, each of which is connected to a pair of cams with a spring that is adapted to move the cam forward and backward.

[0006] The beneficial effects of the utility model are:

[0007] When the drawer is automatically reset by the pulling force at the pull wire, the spring buffer plate at the extension groove will be synchronously mobilized to reset, so that under the abutment between the spring buffer plate and the shock-absorbing plate, the spring connected to the spring buffer plate is used for buffering, thereby reducing the impact force and better maintaining the abutment surface between the outer box and the drawer.

[0008] The slide bar is slidably arranged in the inner cavity of the buffer cylinder, and the impact force received by the spring buffer plate and the shock absorbing plate is further buffered and reduced through interception between the buffer spring and the slide bar.

[0009] During the movement of the sliding rod, the gap between the sliding rod and the inner cavity of the buffer tube gradually decreases, thereby limiting the exchange speed of the high-viscosity lubricating oil. The closer the two are, the smaller the gap is, the slower the exchange speed of the high-viscosity lubricating oil is, and the slower the movement speed of the sliding rod is, until the sliding rod slowly stops, thereby preventing the drawer from colliding with the abutment surface of the outer box, thereby realizing the automatic reset function of the drawer.

A spring buffer plate 24 capable of sliding forward and backward, the spring buffer plate 24 can abut against the shock absorbing plate 25, a high-viscosity lubricating oil is provided in the buffer cylinder 19, the rear end portion of the inner cavity of the buffer cylinder 19 is constricted, the portion of the slide rod 26 located in the buffer cylinder 19 is arranged in a frustum, the portion of the slide rod 26 located in the buffer cylinder 19 and the rear end portions of the slide rod 26 and the buffer cylinder 19 are connected with a buffer spring 27, the drawer 11 and the outer box 10 are both fixed with magnets 21, and the two adjacent magnets 21 cooperate with each other by magnetic force;

[0024] When in use, the drawer 11 is pulled out of the outer box 10 by holding the handle 12 on the front end surface of the drawer 11. The drawer 11 slides forward and backward in cooperation with the outer box 10 through four guide slides 14 distributed up, down, left and right. In the process of pulling out the drawer 11, the user needs to overcome the magnetic attraction between two adjacent magnets 21 and the pulling force of the drawer 11 at the pull wire 18;

[0025] When the drawer 11 is pulled out, the drawer 11 drives the fixedly connected limit block 15 to move outward through the guide slide 14, so that the card slot 22 on the limit block 15 is engaged with the card block 23 fixedly connected to the outer box 10. The elastic engagement of the card block 23 with the limit block 15 supports the drawer 11 to offset the pulling force from the pull wire 18, so that the drawer 11 is statically opened and arranged at the outer box 10, and the user can take or put materials into the drawer 11;

[0026] When the limit block 15 is unable to abut against the block 23, the tension at the pull wire 18 is provided by the torsion spring connecting the torsion spring rod 28 and the turntable at the fixed wire drum 16. After the drawer 11 is pulled out of the outer box 10, the torsion spring connected between the turntable at the fixed wire drum 16 and the outer periphery of the torsion spring rod 28 elastically deforms, and the torsion force at the torsion spring gradually increases. After the user releases the handle 12, the drawer 11 moves backward under the tension at the pull wire 18. During the process, the tension provided by the pull wire 18 gradually decreases, and the shock absorbing plate 25 is first inserted into the opening 13 to fit with the spring buffer plate 24. , and pushes the spring buffer plate 24 to overcome the spring force and slide forward to perform the first layer of buffering. After the damping plate 25 is subjected to the reaction force at the spring buffer plate 24, the slide bar 26 fixedly connected to the damping plate 25 moves backward, and the buffer spring 27 is stretched by the tension. During the movement of the slide bar 26, the gap between the slide bar 26 and the inner cavity of the buffer cylinder 19 gradually decreases, thereby limiting the exchange speed of the high-viscosity lubricating oil. The closer the two are, the smaller the gap is, the slower the exchange speed of the high-viscosity lubricating oil is, and the slower the movement speed of the slide bar 26 is, until the slide bar 26 slowly stops;

[0027] The drawer 11 is relatively stably arranged on the outer box 10 and remains in a stationary state through the magnetic attraction between two adjacent magnets 21 .

[0028] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
