Description

Technical Field

[0001] The present application relates to the field of construction cost, and more specifically, to a novel device for collecting construction project cost data. Background Art

[0002] In the construction cost work, it is necessary to predict, calculate, analyze and other work on the materials, labor, design, etc. of the project, so it is necessary to collect and save the paper document data related thereto. The patent document with the prior art publication number CN212066155U provides a construction cost data collection and storage device. The device can place the file bags in front and back layers by setting up multiple file placement boxes and a pushing mechanism. Files that do not need to be frequently consulted are placed in the file placement box on the rear side, and files that need to be frequently consulted are placed in the file placement box on the front side. This makes it easy to query the files and can store more files.

[0003] In view of the above-mentioned related technologies, the inventor believes that although the file storage box can store file documents, it has a simple structure. Due to the different thicknesses of files of different categories, it is difficult for the device to stably clamp files of different thicknesses, and the placement stability is poor. Therefore, we propose a new type of construction project cost data collection device. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, this application provides a new type of construction project cost data collection device.

[0005] The present application provides a novel construction engineering cost data collection device, which adopts the following technical solution:

[0006] A novel construction project cost data collection device comprises a box body, a plurality of placement slots are connected to the box body, a pressure plate is elastically connected to the placement slots, the pressure plate is used to flatten documents, guide wheels are rotatably connected to both sides of the pressure plate, the guide wheels are in rolling contact with guide slots provided in the box body, and a rotating shaft is rotatably connected to the box body, one end of the rotating shaft passes through the box body and is fixedly connected to a rotating rod, a plurality of connecting rods are fixedly connected to the rotating shaft, and the connecting rods are used to drive the placement slots to move.

[0007] By adopting the above technical solution, when the placement slot is inside the box, the pressure plate can press and limit the documents in the placement slot. When the rotating rod is rotated, the rotation cooperates with the connecting rod to drive the placement slot to move. Multiple placement slots slide out of the box. The guide wheel cooperates with the guide slot to drive the pressure plate to rise, so that the pressure plate cancels the limit on the documents, making it easier to place or take documents.

[0008] Optionally, the bottom of the placement groove is a rectangular structure with four rollers, wherein the roller placement groove on one side is rotatably connected and rollingly connected to a slide groove opened on the box body, and the roller on the other side is rotatably connected to the box body and rollingly contacts the placement groove.

[0009] By adopting the above technical solution, the rollers can reduce the movement resistance and noise when the placement slot is translated, making it easier and smoother to use.

[0010] Optionally, the pressing plate is slidably connected to the placement slot, and the corners of the pressing plate are elastically connected to the placement slot via springs A.

[0011] By adopting the above technical solution, the guide groove has a bent structure. When the guide wheel is located at the lower end of the guide groove, the spring A is in a contracted state and drives the pressure plate to descend, so that the pressure plate can press and limit the placed documents to ensure stable placement.

[0012] Optionally, the lengths of the plurality of connecting rods increase sequentially from top to bottom, one side of the placement slot is fixedly connected to a limiting frame, and the connecting rod is slidably connected to the limiting frame.

[0013] By adopting the above technical solution, when the rotating shaft drives the multiple connecting rods to rotate, the connecting rods cooperate with the limit frames to open the multiple placement slots in a stepped shape, making it easy to take and place files on the multiple placement slots.

[0014] Optionally, both ends of the rotating shaft are sleeved with torsion springs, and both ends of the torsion springs are respectively connected and fixed to the rotating shaft and the box body.

[0015] By adopting the above technical solution, when the rotating shaft rotates to drive the placement slot to slide outward, the torsion spring accumulates force, and when the rotating shaft rotates in the opposite direction, the torsion spring is reset to facilitate driving the placement slot to slide in the opposite direction.

[0016] Optionally, one side of the box body is symmetrically structured with two door hingedly connected.

[0017] By adopting the above technical solution, the box door is hinged to the box body through the spring hinge. When the placement slot slides to the outside of the box body, the box door can be automatically pushed open. After the placement slot returns to the box body, the box door is automatically closed.

[0018] Optionally, a locking rod is slidably connected to the rotating rod, the locking rod is elastically connected to the rotating rod via a spring B, and a plurality of locking grooves for plugging and cooperating with the locking rod are provided on the box body.

[0019] By adopting the above technical solution, when the rotating rod is rotated to a certain angle to make the placement slot slide out of the box body, and when the placement slot is located in the box body, the spring B can drive the locking rod to descend and plug into the locking slot at the corresponding position. At this time, the rotating shaft cannot rotate, so that the placement slot remains stable.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. When the rotating shaft is driven to rotate by the rotating rod, the connecting rod cooperates with the driving frame to make multiple placement slots slide out of the box body and spread out in a stepped shape, which is convenient for taking and placing documents on the placement slots. After the placement slots are moved into the box body, the guide wheels roll along the guide slots, so that the spring A drives the pressure plate to descend, thereby automatically pressing and limiting the documents, and the stability is good.

[0022] 2. When the placement slot is unfolded or located in the box, spring B drives the lock rod to engage with the lock slot, so that the shaft cannot rotate, thereby keeping the placement slot stable and preventing accidental sliding, further improving stability.
